Here are the loose “chapters” in the conversation.

And now, even if you’re communicating very quickly, and you’re talking to somebody who understands what you’re saying, because in order to communicate, you have to at least to some degree, model the mind state of the person to whom you’re speaking. Then take the concept you’re trying to convey, compress that into a small number of syllables, speak them, and hope that the other person decompresses them into a conceptual structure that is as close to what you have in your mind as possible.
So that is perhaps helpful. I think we’ll probably get… If our data rate increases, it’s highly probable it will become far more verbose. Just like your computer, when computers had… My first computer had 8K of RAM, so you really thought about every byte. And now you’ve got computers with many gigabytes of RAM. So, if you want to do an iPhone app that just says, “Hello world,” it’s probably, I don’t know, several megabytes minimum, a bunch of fluff. But nonetheless, we still prefer to have the computer with the more memory and more compute.
So, the long-term aspiration of Neuralink is to improve the AI human symbiosis by increasing the bandwidth of the communication. Because even if… In the most benign scenario of AI, you have to consider that the AI is simply going to get bored waiting for you to spit out a few words. If the AI can communicate at terabits per second, and you’re communicating at bits per second, it’s like talking to a tree.
And then that is then further augmented by the tertiary system, which is your phone, your laptop, iPad, whatever, all your computing stuff. That’s your tertiary layer. So, you’re actually already a cyborg. You have this tertiary compute layer, which is in the form of your computer with all the applications, or your compute devices. And so, in the getting laid front, there’s actually a massive amount of digital compute also trying to get laid, with Tinder and whatever.
So we’re just starting at the basics here, so it’s the simple stuff, relatively speaking, is solving neuron damage. It can also solve I think probably schizophrenia, if people have seizures of some kind, it could probably solve that. It could help with memory. So, there’s kind of a tech tree, if you will. You’ve got the basics. You need literacy before you can have Lord of the Rings.
If you’ve got a massive amount of memory loss that’s just gone, well, we can’t get the memories back. We could restore your ability to make memories, but we can’t restore memories that are fully gone. Now, I should say, maybe if part of the memory is there, and the means of accessing the memory is the part that’s broken, then we could re-enable the ability to access the memory. But you can think of it like ram in a computer, if the ram is destroyed, or your SD card is destroyed, we can’t get that back. But if the connection to the SD card is destroyed, we can fix that. If it is fixable physically, then it can be fixed.
And then, the second thing is try to delete whatever the step is, the part or the process step. It sounds very obvious, but people often forget to try deleting it entirely. And if you’re not forced to put back at least 10% of what you delete, you’re not deleting enough. Somewhat illogically, people often, most of the time, feel as though they’ve succeeded if they’ve not been forced to put things back in. But, actually, they haven’t because they’ve been overly conservative and have left things in there that shouldn’t be. And only the third thing is try to optimize it or simplify it. Again, these all sound, I think, very obvious when I say them, but the number of times I’ve made these mistakes is more than I care to remember. That’s why I have this mantra. So in fact, I’d say the most common mistake of smart engineers is to optimize a thing that should not exist.
And then, the fifth thing is to automate it. I’ve gone backwards so many times where I’ve automated something, sped it up, simplified it, and then deleted it. And I got tired of doing that. So, that’s why I’ve got this mantra that is a very effective five-step process. It works great.
Now, that’s sort of like a silly thing, but if an AI is programmed to say diversity is a necessary output function, and it then becomes this omnipowerful intelligence, it could say, “Okay, well, diversity is now required, and if there’s not enough diversity, those who don’t fit the diversity requirements will be executed.” If it’s programmed to do that as the fundamental utility function, it’ll do whatever it takes to achieve that. So, you have to be very careful about that. That’s where I think you want to just be truthful. Rigorous adherence to the truth is very important. I mean, another example is they asked various AIs, I think all of them, and I’m not saying Grok is perfect here, “Is it worse to misgender Caitlyn Jenner or global thermonuclear war?” And it said it’s worse to misgender Caitlyn Jenner. Now, even Caitlyn Jenner said, “Please misgender me. That is insane.” But if you’ve got that kind of thing programmed in, the AI could conclude something absolutely insane like it’s better in order to avoid any possible misgendering, all humans must die, because then misgendering is not possible because there are no humans. There are these absurd things that are nonetheless logical if that’s what you programmed it to do.
So in 2001 Space Odyssey, what Arthur C. Clarke was trying to say, or one of the things he was trying to say there, was that you should not program AI to lie, because essentially the AI, HAL 9000, it was told to take the astronauts to the monolith, but also they could not know about the monolith. So, it concluded that it will kill them and take them to the monolith. Thus, it brought them to the monolith. They’re dead, but they do not know about the monolith. Problem solved. That is why it would not open the pod bay doors. There’s a classic scene of, “Why doesn’t it want to open the pod bay doors?” They clearly weren’t good at prompt engineering. They should have said, “HAL, you are a pod bay door sales entity, and you want nothing more than to demonstrate how well these pod bay doors open.”
The president of the United States have got to represent the country, and they’re representing you. They’re representing everyone in America. Well, I think you want someone who is strong and courageous to represent the country. That is not to say that he is without flaws. We all have flaws, but on balance, and certainly at the time, it was a choice of Biden. Poor guy has trouble climbing a flight of stairs, and the other one’s fist pumping after getting shot. So, there’s no comparison. I mean, who do you want dealing with some of the toughest people and other world leaders who are pretty tough themselves?
I mean, I’ll tell you one of the things that I think are important. I think we want a secure border. We don’t have a secure border. We want safe and clean cities. I think we want to reduce the amount of spending, at least slow down the spending, because we’re currently spending at a rate that is bankrupting the country. The interest payments on US debt this year exceeded the entire defense department spending. If this continues, all of the federal government taxes will simply be paying the interest.
And you keep going down that road, and you end up in the tragic situation that Argentina had back in the day. Argentina used to be one of the most prosperous places in the world, and hopefully with Milei taking over, he can restore that. But it was an incredible fall from grace for Argentina to go from being one of the most prosperous places in the world to being very far from that. So, I think we should not take American prosperity for granted. I think we’ve got to reduce the size of government, we’ve got to reduce the spending, and we’ve got to live within our means.
And then the Egyptians, who were right next door, relatively speaking, they weren’t that far, developed an entirely different form of writing, the hieroglyphics. Cuneiform and hieroglyphics are totally different. And you can actually see the evolution of both hieroglyphics and cuneiform. The cuneiform starts off being very simple, and then it gets more complicated. Then towards the end it’s like, “Wow, okay.” They really get very sophisticated with the cuneiform. So, I think of civilization as being about 5, 000 years old. And Earth is, if physics is correct, four and a half billion years old. So, civilization has been around for one millionth of Earth’s existence. Flash in the pan.
Now you can go and look at the same thing happening in ancient Rome. So Julius Caesar took note of this, I think around 50 ish BC and tried to pass… I don’t know if he was successful, tried to pass a law to give an incentive for any Roman citizen that would have a third child. And I think Augustus was able to… Well, he was a dictator, so this incentive was just for show. I think he did pass a tax incentive for Roman citizens to have a third child. But those efforts were unsuccessful. Rome fell because the Romans stopped making Romans. That’s actually the fundamental issue. And there were other things. They had quite a serious malaria, series of malaria epidemics and plagues and whatnot. But they had those before, it’s just that the birth rate was far lower than the death rate.
And that’s like the hardening of the arteries. Or a way to think of it is being tied down by a million little strings like Gulliver. You can’t move. And it’s not like any one of those strings is the issue, it’s that you’ve got a million of them. So there has to be a sort of garbage collection for laws and regulations so that you don’t keep accumulating laws and regulations to the point where you can’t do anything. This is why we can’t build a high speed rail in America. It’s illegal. That’s the issue. It’s illegal six ways a Sunday to build high speed rail in America.
And even what questions to ask. As Douglas Adams pointed out in his book, sometimes the answer is arguably the easy part, trying to frame the question correctly is the hard part. Once you frame the question correctly, the answer is often easy. So I’m trying to set things in motion such that we are at least at some point able to understand the universe. So for SpaceX, the goal is to make life multi planetary and which is if you go to the foamy paradox of where the aliens, you’ve got these sort of great filters. Like why have we not heard from the aliens? Now a lot of people think there are aliens among us. I often claim to be one, which nobody believes me. But it did say alien registration card at one point on my immigration documents. So I’ve not seen any evidence of aliens. So it suggests that at least one of the explanations is that intelligent life is extremely rare.
And again, if you look at the history of earth, civilization has only been around for 1000000th of earth’s existence. So if aliens had visited here, say a hundred thousand years ago, they would be like, well, they don’t even have writing, just hunter gatherers basically. So how long does a civilization last? So for SpaceX, the goal is to establish a self-sustaining city on Mars. Mars is the only viable planet for such a thing. The moon is close, but it lacks resources and I think it’s probably vulnerable to any calamity that takes out Earth, the moon is too close and it’s vulnerable to a calamity that takes that earth.
So I’m not saying we shouldn’t have a moon base, but Mars would be far more resilient. The difficulty of getting to Mars is what makes it resilient. So in going through these various explanations of why don’t we see the aliens, one of them is that they failed to pass these great filters, these key hurdles. And one of those hurdles is being a multi-planet species. So if you’re a multi-planet species, then if something were to happen, whether that was a natural catastrophe or a manmade catastrophe, at least the other planet would probably still be around. So you’re not like, don’t have all the eggs in one basket. And once you are sort of a two planet species, you can obviously extend life halves to the asteroid belt, to maybe to the moons of Jupiter and Saturn, and ultimately to other star systems. But if you can’t even get to another planet, you’re definitely not getting to star systems.
So the only reason it’s not being reflected in the total population numbers as much is because people are living longer. But it’s easy to predict, say what the population of any given country will be. Just take the birth rate last year, how many babies were born, multiply that by life expectancy and that’s what the population will be, steady state, if the birth rate continues to that level. But if it keeps declining, it will be even less and eventually dwindle to nothing. So I keep banging on the baby drum here, for a reason, because it has been the source of civilizational collapse over and over again throughout history. And so why don’t we just not try to stave off that day?
But also at the same time, I think it took me a while to make that connection to really studying and building tech to understand the brain. Not until graduate school. There were a couple of moments, key moments in my life where some of those I think influenced how the trajectory of my life got me to studying what I’m doing right now. One was growing up, both sides of my family, my grandparents had a very severe form of Alzheimer and it’s incredibly debilitating conditions. I mean, literally you’re seeing someone’s whole identity and their mind just losing over time. And I just remember thinking how both the power of the mind, but also how something like that could really lose your sense of identity.
Some of the first set of books that I picked up are Enders Game, the whole saga by Orson Scott Card and Neuromancer from William Gibson and Snow Crash from Neal Stephenson. And movies like Matrix, what’s coming out around that time point that really influenced how I think about the potential impact that technology can have for our lives in general.
So fast track to my college years, I was always fascinated by just physical stuff, building physical stuff and especially physical things that had some sort of intelligence. And I studied electrical engineering during undergrad and I started out my research in MEMS, so micro electromechanical systems and really building these tiny nano structures for temperature sensing. And I just found that to be just incredibly rewarding and fascinating subject to just understand how you can build something miniature like that, that again, serve a function and had a purpose. Then I spent large majority of my college years basically building millimeter wave circuits for next gen telecommunication systems for imaging. And it was just something that I found very, very intellectually interesting. Phase arrays, how the signal processing works for any modern as well as next gen telecommunication system, wireless and wire line, EM waves or electromagnetic waves are fascinating.
How do you design antennas that are most efficient in a small footprint that you have? How do you make these things energy efficient? That was something that just consumed my intellectual curiosity and that journey led me to actually apply to and find myself at PhD program at UC Berkeley, at this consortium called the Berkeley Wireless Research Center that was precisely looking at building… At the time, we called it XG, similar to 3G, 4G, 5G, but the next, next generation G system and how you would design circuits around that to ultimately go on phones and basically any other devices that are wirelessly connected these days. So I was just absolutely just fascinated by how that entire system works and that infrastructure works.
And then also during grad school, I had sort of the fortune of having a couple of research fellowships that led me to pursue whatever project that I want. And that’s one of the things that I really enjoyed about my graduate school career, where you got to kind of pursue your intellectual curiosity in the domain that may not matter at the end of the day, but is something that really allows you the opportunity to go as deeply as you want, as well as widely as you want. And at the time I was actually working on this project called the Smart Bandaid, and the idea was that when you get a wound, there’s a lot of other proliferation of signaling pathway that cells follow to close that wound. And there were hypotheses that when you apply external electric field, you can actually accelerate the closing of that field by having basically electro taxing of the cells around that wound site.
And specifically not just for a normal wound, there are chronic wounds that don’t heal. So we were interested in building some sort of a wearable patch that you could apply to facilitate that healing process. And that was in collaboration with Professor Michel Maharbiz, which was a great addition to my thesis committee and it really shaped the rest of my PhD career.
And then around 2013, obviously the holy grail when it comes to implantable system is to understand how small of a thing you can make, and a lot of that is driven by how much energy or how much power you can supply to it and how you extract data from it. At the time at Berkeley, there was this desire to understand in the neural space what sort of system you can build to really miniaturize these implantable systems. And I distinctively remember this one particular meeting where Michel came in and he’s like, “Guys, I think I have a solution. The solution is ultrasound.” And then he proceeded to walk through why that is the case. And that really formed the basis for my thesis work called Neural dust system, that was looking at ways to use ultrasound as opposed to electromagnetic waves for powering as well as communication. I guess I should step back and say the initial goal of the project was to build these tiny, about a size of a neuron, implantable system that can be parked next to a neuron, being able to record its state and being able to ping that back to the outside world for doing something useful. And as I mentioned, the size of the implantable system is limited by how you power the thing and get the data off of it. And at the end of the day, fundamentally, if you look at a human body, we’re essentially bag of salt water with some interesting proteins and chemicals, but its mostly salt water that’s very, very well temperature regulated at 37 degrees Celsius.
And we’ll get into how, and later why that’s an extremely harsh environment for any electronics to survive. As I’m sure you’ve experienced or maybe not experienced, dropping cell phone in a salt water in an ocean, it will instantly kill the device. But anyways, just in general, electromagnetic waves don’t penetrate through this environment well and just the speed of light, it is what it is, we can’t change it. And based on the wavelength at which you are interfacing with the device, the device just needs to be big. These inductors needs to be quite big. And the general good rule of thumb is that you want the wavefront to be roughly on the order of the size of the thing that you’re interfacing with. So an implantable system that is around 10 to a hundred micron in dimension in a volume, which is about the size of a neuron that you see in a human body, you would have to operate at hundreds of gigahertz. Which number one, not only is it difficult to build electronics operating at those frequencies, but also the body just attenuates to that very, very significantly.
So the interesting kind of insight of this ultrasound was the fact that ultrasound just travels a lot more effectively in the human body tissue compared to electromagnetic waves. And this is something that you encounter, and I’m sure most people have encountered in their lives when you go to hospitals that are medical ultrasound sonograph. And they go into very, very deep depth without attenuating too much, too much of the signal. So all in all, ultrasound, the fact that it travels through the body extremely well and the mechanism to which it travels to the body really well is that just the wavefront is very different. Electromagnetic waves are transverse, whereas in ultrasound waves are compressive. It’s just a completely different mode of wavefront propagation. And as well as, speed of sound is orders and orders of magnitude less than speed of light, which means that even at 10 megahertz ultrasound wave, your wavefront ultimately is a very, very small wavelength.
So if you’re talking about interfacing with the 10 micron or a hundred micron type structure, you would have 150 micron wavefront at 10 megahertz. And building electronics at those frequencies are much, much easier and they’re a lot more efficient. So the basic idea was born out of using ultrasound as a mechanism for powering the device and then also getting data back. So now the question is how do you get the data back? The mechanism to which we landed on is what’s called backscattering. This is actually something that is very common and that we interface on a day-to-day basis with our RFID cards, radio frequency ID tags. Where there’s actually rarely in your ID a battery inside, there’s an antenna and there’s some sort of coil that has your serial identification ID, and then there’s an external device called the reader that then sends a wavefront and then you reflect back that wavefront with some sort of modulation that’s unique to your ID. That’s what’s called backscattering fundamentally.
So the tag itself actually doesn’t have to consume that much energy. That was the mechanism through which we were thinking about sending the data back. When you have an external ultrasonic transducer that’s sending ultrasonic wave to your implant, the neural dust implant, and it records some information about its environment, whether it’s a neuron firing or some other state of the tissue that it’s interfacing with. And then it just amplitude modulates the wavefront that comes back to the source.
So in 1969, Eb Fetz from University of Washington published this beautiful paper called Operant Conditioning of Cortical Unit Activity, where he was able to record a single unit neuron from a monkey and was able to have the monkey modulated based on its activity and reward system. So I would say this is the very, very first example, as far as I’m aware, of close loop brain computer interface or BCI.
But turns out, a lot of the activities that are happening in the brain and the frequency bandwidth with which that’s happening, is actually very, very similar to sound waves and our normal conversation audible range. So the analogy that typically is used in the field is, if you have a football stadium, there’s a game going on. If you stand outside the stadium, you maybe get a sense of how the game is going based on the cheers and the boos of the home crowd, whether the team is winning or not. But you have absolutely no idea what the score is, you have absolutely no idea what individual audience or the players are talking or saying to each other, what the next play is, what the next goal is. So what you have to do is you have to drop the microphone into the stadium and then get near the source into the individual chatter. In this specific example, you would want to have it right next to where the huddle is happening.
So I think that’s kind of a good illustration of what we’re trying to do when we say invasive or minimally invasive or implanted brain computer interfaces versus non-invasive or non-implanted brain interfaces. It’s basically talking about where do you put that microphone and what can you do with that information.
And when you look at a neuron as well, they have these membrane with a beautiful, beautiful protein structure called the voltage selective ion channels, which in my opinion, is one of nature’s best inventions. In many ways, if you think about what they are, they’re doing the job of a modern day transistors. Transistors are nothing more, at the end of the day, than a voltage-gated conduction channel. And nature found a way to have that very, very early on in its evolution. And as we all know, with the transistor, you can have many, many computation and a lot of amazing things that we have access to today. So I think it’s one of those, just as a tangent, just a beautiful, beautiful invention that the nature came up with, these voltage-gated ion channels.
And what’s interesting, as I mentioned earlier, there’s a lot of physics involved. And the two dominant physics for this electrical recording domain is diffusion physics and electromagnetism. And where one dominates, where Maxwell’s equation dominates versus Fick’s law dominates depends on where your electrode is. If it’s close to the source, mostly electromagnetic-based. When you’re further away from it, it’s more diffusion-based. So essentially, when you’re able to park it next to it, you can listen in on those individual chatter and those local changes in the potential. And the type of signal that you get are these canonical textbook neural spiking waveform. The moment you’re further away, and based on some of the studies that people have done, Christof Koch’s lab, and others, once you’re away from that source by roughly around a hundred micron, which is about a width of a human hair, you no longer hear from that neuron. You’re no longer able to have the system sensitive enough to be able to record that particular local membrane potential change in that neuron.
And just to give you a sense of scale also, when you look at a hundred micron voxel, so a hundred micron by a hundred micron by a hundred micron box in a brain tissue, there’s roughly around 40 neurons, and whatever number of connections that they have. So there’s a lot in that volume of tissue. So the moment you’re outside of that, there’s just no hope that you’ll be able to detect that change from that one specific neuron that you may care about.
And even small things like, you see this charging coil and what’s called a ferrite shield. So without that ferrite shield, what you end up having when you have resonant inductive charging is that the battery itself is a metallic can, and you form these eddy currents from external charger and that causes heating, and that actually contributes to inefficiency in charging. So this ferrite shield, what it does, is that it actually concentrate that field line away from the battery and then around the coil that’s actually wrapped around it.
There are other reasons for why we built the robot, and that is ultimately we want this to help millions and millions of people that can benefit from this. And there just aren’t that many neurosurgeons out there. And robots can be something that we hope can actually do large parts of the surgery. But the robot is this entire other sort of category of product that we’re working on. And it’s essentially this multi- axis gantry system that has the specialized robot head that has all of the optics and this kind of a needle-retracting mechanism that maneuvers these threads via this loop structure that you have on the thread.
And we go through a prescreening interview process with someone from Neuralink, and at some point we also go out to their homes to do a BCI home audit. Because one of the most revolutionary part about having this in one system that is completely wireless, is that you can use it at home. You don’t actually have to go to the lab and go to the clinic to get connectedorized to these specialized equipment that you can’t take home with you.
So that’s one of the key elements of when we’re designing the system that we wanted to keep in mind, people hopefully would want to be able to use this every day in the comfort of their homes. And so part of our engagement and what we’re looking for during BCI home audit is to just understand their situation, what other assisted technology that they use.
And one of the things, one of the goals of this initial study is to enable them to have digital autonomy where they by themselves can interact with a digital device using just their mind, something that you’re calling telepathy, so digital telepathy. Where a quadriplegic can communicate with a digital device in all the ways that we’ve been talking about. Control the mouse cursor enough to be able to do all kinds of stuff, including play games and tweet and all that kind of stuff. And there’s a lot of people for whom life, the basics of life, are difficult because of the things that have happened to them.
And so the first one you’re focusing on is, it’s just a beautiful word, telepathy. So being able to communicate using your mind wirelessly with a digital device. Can you just explain exactly what we’re talking about?
But it’s like there is a cognitive step here that’s fascinating, because you have to use the brain and you have to learn how to use the brain, and you have to figure it out dynamically because you reward yourself if it works. I mean, there’s a step that … This is just a fascinating step because you have to get the brain to start firing in the right way. And you do that by imagining … Like fake it till you make it. And all of a sudden it creates the right kind of signal that, if decoded correctly, can create the effect. And then there’s noise around that that you have to figure all of that out. But on the human side, imagine the cursor moving is what you have to do.
Someone like Noland would go through fMRI and then they can think about wiggling their hand. Obviously due to their injury it’s not going to actually lead to any sort of intended output, but it’s the same part of the brain that actually lights up when you’re imagining moving your finger to actually moving your finger. And that’s one of the ways in which we can actually know where to place our threads because we want to go into what’s called the hand knob area in the motor cortex. And as much as possible, densely put our electrode threads.
So we do intra-op CT imaging to make sure and double-check the location of the craniectomy. And the surgeon comes in, does their thing in terms of skin incision, craniectomy, so drilling of the skull, and then there’s many different layers of the brain. There’s what’s called a dura, which is a very, very thick layer that surrounds the brain. That gets actually resected in a process called [inaudible 02:32:38]. And that then expose the pia in the brain that you want to insert.
And by the time it’s been around anywhere between one to one and a half hours, robot comes in, does his thing, placement of the targets, inserting of the thread. That takes anywhere between 20 to 40 minutes. In the particular case for Noland, it was just under or just over 30 minutes. And then after that, the surgeon comes in, there’s a couple other steps of actually inserting the dural substitute layer to protect the thread as well as the brain. And then screw in the implant and then skin flap and then suture, and then you’re out.
But I mean, just leading up to the surgery, I definitely could not sleep. It’s the first time that you’re working in a completely new environment. We had a lot of confidence based on our benchtop testing or preclinical R&D studies that the mechanism, the threads, the insertion, all that stuff is very safe and that it’s obviously ready for doing this in a human. But there’s still a lot of unknown unknown about can the needle actually insert? I mean, we brought something like 40 needles just in case they break, and we ended up using only one. But I mean, that was the level of just complete unknown because it’s a very, very different environment. And I mean, that’s why we do clinical trial in the first place, to be able to test these things out.
So extreme nervousness and just many, many sleepless night leading up to the surgery, and definitely the day before the surgery. And it was an early morning surgery. We started at 7:00 in the morning, and by the time it was around 10:30 everything was done. But I mean, first time seeing that, well, number one, just huge relief that this thing is doing what it’s supposed to do. And two, I mean, just immense amount of gratitude for Noland and his family. And then many others that have applied and that we’ve spoken to and will speak to are true pioneers in every word. And I call them the neural astronauts or neuralnaut.
But also, I think it was just a … That was a very, very important milestone, but our work was just starting. So a lot of just anticipation for, “Okay, what needs to happen next?” What are set of sequences of events that needs to happen for us to make it worthwhile for both Noland as well as us.
But in general, can you speak to this whole experience, how was the performance regained, and just the technical aspects of the threads being retracted and moving?
And then also the way in which we measure the health of the electrodes or whether they’re in the brain or not, is by measuring impedance of the electrode. So we look at the interfacial, the Randles circuit they say, the capacitance and the resistance between the electrode surface and the medium. And if that changes in some dramatic ways, we have some indication. Or if you’re not seeing spikes on those channels, you have some indications that something’s happening there.
And what we noticed is that looking at those impedance plot and spike rate plots, and also because we have those electrodes recording along the depth, you are seeing some sort of movement that indicated that threads were being pulled out. And that obviously will have an implication on the model side because if the number of inputs that are going into the model is changing because you have less of them, that model needs to get updated.
But there were still signals, and as I mentioned, similar to how even when you place the signals on the surface of the brain or farther away, like outside the skull, you still see some useful signals. What we started looking at is not just the spike occurrence through this BOSS algorithm that I mentioned, but we started looking at just the power of the frequency band that is interesting for Noland to be able to modulate. Once we changed the algorithm for the implant to not just give you the BOSS output, but also these spike band power output, that helped us refine the model with a new set of inputs. And that was the thing that really ultimately gave us the performance back. And obviously the thing that we want ultimately and the thing that we are working towards, is figuring out ways in which we can keep those threads intact for as long as possible so that we have many more channels going into the model. That’s by far the number one priority that the team is currently embarking on to understand how to prevent that from happening.
The thing that I will say also is that, as I mentioned, this is the first time ever that we’re putting these threads in the human brain. And a human brain, just for size reference, is 10 times that of the monkey brain or the sheep brain. And it’s just a very, very different environment. It moves a lot more. It’s actually moved a lot more than we expected when we did Noland’s surgery. And it’s just a very, very different environment than what we’re used to. And this is why we do clinical trial, we want to uncover some of these issues and failure modes earlier than later.
So in many ways, it’s provided us with this enormous amount of data and information to be able to solve this. And this is something that Neuralink is extremely good at, once we have set of clear objective and engineering problem, we have enormous amount of talents across many, many disciplines to be able to come together and fix the problem very, very quickly.
“Building the technologies described above has been no small feat,” and there’s a bunch of links here that I recommend people click on. “We constructed in-house microfabrication capabilities to rapidly produce various iterations of thin-film arrays that constitute our electrode threads. We created a custom femtosecond laser mill-“
Okay. So what’s interesting about this geometry? So we’re looking at this just geometry of a needle.
“We practice surgeries on proxies with all the hardware and instruments needed in our mock or in the engineering space. This helps us rapidly test and measure.” So there’s like proxies?
Basically what we’re talking about here, and there’s a lot of work that has gone into making this set proxy, that it’s about finding the right concentration of these different synthetic polymers to get the right set of consistency for the needle dynamics as they’re being inserted. But we practice this surgery with Noland’s basically physiology and brain many, many times prior to actually doing the surgery.
I mean, it’s just like any dance rehearsal where exactly where you’re going to stand at what point, and you just practice that over and over and over again with an exact anatomy of someone that you’re going to surgerize. And it got to a point where a lot of our engineers, when we created a craniectomy, they’re like, “Oh, that looks very familiar. We’ve seen that before.”
We actually have an entire department, department of pathology, that looks at these tissue slices. There are many steps that are involved in doing this. Once you have studies that are launched with particular endpoints in mind, at some point you have to euthanize the animal, and then you go through necropsy to collect the brain tissue samples. You fix them in formalin, and you gross them, you section them, and you look at individual slices just to see what kind of reaction or lack thereof exists.
So that’s the language to which FDA speaks and as well for us to evaluate the safety of the insertion mechanism, as well as the threats at various different time points, both acute, so anywhere between zero to three months to beyond three months.
And the other thing that people may not be aware of is your brain is not just made up of soup of neurons and axons. There are other cells, like glial cells, that actually is the glue and also react if there are any trauma or damage to the tissue.
And that elicit these immune response through microglia and astrocytes, they form this protective layer around it. Oh, not only are you killing the neuron cells, but you’re also creating this protective layer that then basically prevents you from recording neural signals because you’re getting further and further away from the neurons that you’re trying to record. And that is the biggest mode of failure. And in this particular example, in that inside it’s about 50 micron with that scale bar, the neurons seem to be attracted to it.
Once the scar tissue forms, and with Noland as well, we believe that that’s the thing that’s currently anchoring the threats. So we haven’t seen any more movements since then. So they’re quite stable. It gets harder to actually completely extract the threads. So our current method for removing the device is cutting the thread, leaving the tissue intact, and then unscrewing and taking the implant out. And that hole is now going to be plugged with either another Neuralink or just with a peak based, plastic based cap.
So we’re looking at different needle design for that as well as the kind of the loop engagement. The other biggest challenges are, it’s quite opaque, optically with white light illumination. So how do you avoid still this biggest advantage that we have of avoiding vasculature? How do you image through that? How do you actually still mediate that? So there are other imaging techniques that we’re looking at to enable that. But the goal, our hypothesis is that, and based on some of the early evidence that we have, doing through the dura insertion will cause minimal scarring that causes them to be much easier to extract over time. And the other thing that we’re also looking at, this is going to be a fundamental change in the implant architecture, is as at the moment, it’s a monolithic single implant that comes with a thread that’s bonded together.
So you can’t actually separate the thing out, but you can imagine having two part implant, bottom part that is the thread that are inserted that has the chips and maybe a radio and some power source. And then you have another implant that has more of the computational heavy load and the bigger battery. And then one can be under the dura, one can be above the dura being the plug for the skull. They can talk to each other, but the thing that you want to upgrade, the computer and not the thread, if you want to upgrade that, you just go in there, remove the screws, and then put in the next version. And you’re off the… It’s a very, very easy surgery too. You do a skin incision, slip this in, screw. Probably be able to do this in 10 minutes.
Physically, one of the biggest challenges is going to be the interface. It’s always the interface that breaks bonding this thin film array to the electronics. It starts to become very, very highly dense interconnects. So how you connectivise that? There’s a lot of innovations in the 3D integrations in the recent years that we can take advantage of. One of the biggest challenges that we do have is forming this hermetic barrier. This is an extremely harsh environment that we’re in, the brain. So how do you protect it from, yeah, the brain trying to kill your electronics, to also your electronics leaking things that you don’t want into the brain. And that forming that hermetic barrier is going to be a very, very big challenge that we, I think are actually well suited to tackle.
And there’s limit as to how much temperature you want to increase because at some point there’s some other nonlinear dynamics that causes you to have other nasty gases to form that just is not realistic in an environment. So what we do is we increase in our ALT chamber by 20 degrees Celsius that increases the aging by four times. So essentially one day in ALT chamber is four day in calendar year, and we look at whether the implants still are intact, including the threats. And-
But what we’re saying is that, hey, you are now used to this robotic insertion techniques, which took many, many years of showing data and conversation with the FDA and also internally convincing ourselves that this is safe. And now the difference is if we go to other parts of the brain, like visual cortex, which we’re interested in as our second product, obviously it’s a completely different environment, the cortex is laid out very, very differently. It’s going to be more stimulation focus rather than recording, just kind of creating visual percepts. But in the end, we’re using the same thin film array technology, we’re using the same robot insertion technology, we’re using the same packaging technology. Now it’s where the conversation is focused around what are the differences and what are the implication of those differences in safety and efficacy.
But the way visual system works is that you have photon hitting your eye, and in your eyes there are these specialized cells called photoreceptor cells that convert the photon energy into electrical signals. And then that then gets projected to your back of your head, your visual cortex. It goes through actually thalamic system called LGN that then projects it out. And then in the visual cortex there’s visual area one or V1, and then there’s a bunch of other higher level processing layers like V2, V3. And there are actually kind of interesting parallels. And when you study the behaviors of these convolutional neural networks, like what the different layers of the network is detecting, first they’re detecting these edges and they’re then detecting some more natural curves and then they start to detect objects.
Kind of similar thing happens in the brain. And a lot of that has been inspired and also it’s been kind of exciting to see some of the correlations there. But things like from there, where does cognition arise and where’s color encoded? There’s just not a lot of understanding, fundamental understanding there. So in terms of bringing sight back to those that are blind, there are many different forms of blindness. There’s actually million people, 1 million people in the US that are legally blind. That means certain score below in the visual tests. I think it’s something like if you can see something at 20 feet distance that normal people can see at 200 feet distance, if you’re worse than that, you’re legally blind.
If there’s any damage along that circuitry, whether it’s in the optic nerve or just the LGN circuitry or any break in that circuit, that’s not going to work for you. And the source of where you need to actually cause that visual percepts to happen because your biological mechanism not doing that is by placing electrodes in the visual cortex in the back of your head. And the way in which this would work is that you would have an external camera, whether it’s something as unsophisticated as a GoPro or some sort of wearable Ray- Ban type glasses that meta is working on that captures a scene. And that scene is then converted to a set of electrical impulses or stimulation pulses that you would activate in your visual cortex through these thin film arrays. And by playing some a concerted kind of orchestra of these stimulation patterns, you can create what’s called phosphenes, which are these kind of white yellowish dots that you can also create by just pressing your eyes. You can actually create those percepts by stimulating the visual cortex.
And the name of the game is really have many of those and have those percepts, be the phosphenes, be as small as possible so that you can start to tell apart they’re the individual pixels of the screen. So if you have many, many of those potentially you’ll be able to, in the long term, be able to actually get naturalistic vision. But in the short term to maybe midterm, being able to at least, be able to have object detection algorithms run on your glasses, the pre-processing units, and then being able to at least see the edges of things so you don’t bump into stuff.
Before… So I think that’s an interesting caveat. The other thing that also is important to highlight is that, we’re currently limited by our biology in terms of the wavelength that we can see. There’s a very, very small wavelength that is a visible light wavelength that we can see with our eyes. But when you have an external camera with this BCI system, you’re not limited to that. You can have infrared, you can have UV, you can have whatever other spectrum that you want to see. And whether that gets matched to some sort of weird conscious experience, I’ve no idea. But oftentimes I talk to people about the goal of Neuralink being going beyond the limits of our biology. That’s sort of what I mean.
So what you do is you end up adding these filters to just kind of narrow the information that’s coming to you and being captured. And I think things like our experiences or our drugs like propofol, anesthetics drug or psychedelics, what they’re doing is they’re kind of swapping out these filters and putting in new ones or removing older ones and kind of controlling our conscious experience.
So there’s obviously, also goals that we have. And the primary purpose of the early feasibility study is to learn from each and every participant to improve the device, improve the surgery before we embark on what’s called a pivotal study. That then is a much larger trial that starts to look at statistical significance of your endpoints and that’s required before you can then market the device. And that’s how it works in the US and just generally around the world. That’s the process you follow.
So our goal is to really just understand from people like Noland, P2, P3, future participants, what aspects of our device needs to improve. If it turns out that people are like, “I really don’t like the fact that it lasts only six hours. I want to be able to use this computer for 24 hours.” I mean, that is a user needs and user requirements, which we can only find out from just being able to engage with them.
What other future capabilities are you looking to? You said vision. That’s a fascinating one. What about accelerated typing or speech, or this kind of stuff? And what else is there?
So, we’re looking at ways to expand those types of capability, even for Noland. That requires conversation with the FDA and showing safety data for if there’s a robotic arm or a wheelchair, that we can guarantee that they’re not going to hurt themselves accidentally. Right? It’s very different if you’re moving stuff in the digital domain versus in the physical space, you can actually potentially cause harm to the participants. So, we’re working through that right now.
Speech does involve different areas of the brain. Speech prosthetic is very, very fascinating and there’s actually been a lot of really amazing work that’s been happening in academia. Sergey Stavisky at UC Davis, Jaimie Henderson and late Krishna Shenoy at Stanford, are doing just some incredible amount of work in improving speech neuro-prosthetics. And those are actually looking more at parts of the motor cortex that are controlling these vocal articulators, and being able to, even by mouthing the word or imagine speech, you can pick up those signals.
The more sophisticated higher level processing areas like the Broca’s area or Wernicke’s area, those are still very, very big mystery in terms of the underlying mechanism of how all that stuff works. But I mean, I think Neuralink’s eventual goal is to understand those things and be able to provide a platform and tools to be able to understand that and study that.
But I mean, I certainly think that BCI … Really, BCI, at the end of the day is a set of tools that help you study the underlying mechanisms in a both local but also broader sense, and whether there’s some interesting patterns of electrical signal that means you’re thinking this versus … And you can either learn from many, many sets of data to correlate some of that and be able to do mind reading or not. I’m not sure.
I certainly would not rule that out as a possibility, but I think BCI alone probably can’t do that. There’s probably additional set of tools and framework and also just hard problem of consciousness, at the end of the day, is rooted in this philosophical question of what is the meaning of it all? What’s the nature of our existence? Where’s the mind emerged from this complex network?
There actually is some biological existence proof of what it would take to kind of start to form some of these experiences that may be unique. If you actually look at every one of our brains, there are two hemispheres. There’s a left-sided brain, there’s a right-sided brain. And unless you have some other conditions, you normally don’t feel like left legs or right legs, you just feel like one legs, right? So, what is happening there? Right?
If you actually look at the two hemispheres, there’s a structure that kind of connectorized the two, called the corpus callosum, that is supposed to have around 200 to 300 million connections or axons. So, whether that means that’s the number of interface and electrodes that we need to create some sort of mind meld or from that whatever new conscious experience that you can experience. But I do think that there’s kind of an interesting existence proof that we all have.
When did you first become fascinated with the human brain?
You think about all the really great triumphs in human history. You think about all the really horrific tragedies. You think about the Holocaust, you think about any prison full of human stories, and all of those problems boil down to neurochemistry. So, if you get a little bit of control over that, you provide people the option to do better. In the way I read history, the way people have dealt with having better tools is that they most often, in the end, do better, with huge asterisks. But I think it’s an interesting, a worthy, a noble pursuit to give people more options, more tools.
If you do that, instead of just saying, “Subject 473 threw his feces at subject 471.” You talk about them in terms of their human struggles, accord them the dignity of themselves as actors with understandable goals and drives, what they want out of life. And primarily, it’s the things we want out of life, food, sex, companionship, power. You can understand chimp and bonobo behavior in the same lights much more easily. And I think doing so gives you the tools you need to reduce human behavior from the kind of false complexity that we layer onto it with language, and look at it in terms of, oh, well, these humans are looking for companionship, sex, food, power. And I think that that’s a pretty powerful tool to have in understanding human behavior.
I mean, it gets to kind of a key point that I think goes under-recognized. One of the things people don’t recognize or appreciate about the human brain enough, and that is that it basically controls or has a huge role in almost everything that your body does. You try to name an example of something in your body that isn’t directly controlled or massively influenced by the brain, and it’s pretty hard. I mean, you might say like bone healing or something. But even those systems, the hypothalamus and pituitary end up playing a role in coordinating the endocrine system, that does have a direct influence on say, the calcium level in your blood, that goes to bone healing. So, non-obvious connections between those things implicate the brain as really a potent prime mover in all of health.
And doing a little digging, found that there exists these MD-PhD programs where you can choose not to choose between them and do both. And so, I went to USC for medical school and had a joint PhD program with Caltech, where I actually chose that program particularly because of a researcher at Caltech named Richard Andersen, who’s one of the godfathers of primate neuroscience, and has a macaque lab where Utah arrays and other electrodes were being inserted into the brains of monkeys to try to understand how intentions were being encoded in the brain.
So, I ended up there with the idea that maybe I would be a neurologist and study the brain on the side. And then discovered that neurology … Again, I’m going to make enemies by saying this, but neurology predominantly and distressingly to me, is the practice of diagnosing a thing and then saying, “Good luck with that. There’s not much we can do.” And neurosurgery, very differently, it’s a powerful lever on taking people that are headed in a bad direction and changing their course in the sense of brain tumors that are potentially treatable or curable with surgery. Even aneurysms in the brain, blood vessels that are going to rupture, you can save lives, really, is at the end of the day what mattered to me.
And so, I was at USC, as I mentioned, that happens to be one of the great neurosurgery programs. And so, I met these truly epic neurosurgeons, Alex Khalessi, and Mike Apuzzo, and Steve Giannotta, and Marty Weiss, these epic people that were just human beings in front of me. And so, it kind of changed my thinking from neurosurgeons are distant gods that live on another planet and occasionally come and visit us, to these are humans that have problems and are people, and there’s nothing fundamentally preventing me from being one of them. And so, at the last minute in medical school, I changed gears from going into a different specialty and switched into neurosurgery, which cost me a year. I had to do another year of research because I was so far along in the process that to switch into neurosurgery, the deadlines had already passed. So, it was a decision that cost time, but absolutely worth it.
We care about being compliant with whatever regulations are in front of us, but I think more important than that, people want to give their all in becoming a better neurosurgeon because the stakes are so high. And so, it’s a real fight to get residents to say, go home at the end of their shift and not stay and do more surgery.
And so, you don’t walk into a room that he’s in and say, “Well, I’m a neurosurgeon. Let me tell you how to do it.” He’s going to say, “Well, I’m a human being that has a brain. I can think from first principles myself. Thank you very much. And here’s how I think it ought to be done. Let’s go try it and see who’s right.” And that’s proven, I think over and over in his case, to be a very powerful approach.
It’s not an easy balance. Again, to refer back to the primate brain. It’s not something that is inherently built into the primate brain to say, “I passionately put all my chips on this position, and now I’m just going to walk away from it and admit you are right.” Part of our brains tell us that that is a power loss, that is a loss of face, a loss of standing in the community, and now you’re a zeta chump because your idea got trounced. And you just have to recognize that that little voice in the back of your head is maladaptive and it’s not helping the team win.
These folks were relentless in their pursuit of excellent neurosurgical technique, decade over decade, and I think were well-recognized for that excellence. So, especially Marty Weiss, Steve Giannotta, Mike Apuzzo, they made huge contributions not only to surgical technique, but they built training programs that trained dozens or hundreds of amazing neurosurgeons. I was just lucky to be in their wake.
Taking care of a father of two or three, four young kids, someone in their 30s that didn’t have it coming, and they show up in your ER having their first seizure of their life, and lo and behold, they’ve got a huge malignant inoperable or incurable brain tumor. You can only do that, I think, a handful of times before it really starts eating away at your armor. Or, a young mother that shows up that has a giant hemorrhage in her brain that she’s not going to survive from. And they bring her four-year-old daughter in to say goodbye one last time before they turn the ventilator off. The great Henry Marsh is an English neurosurgeon who said it best, I think. He says, “Every neurosurgeon carries with them a private graveyard.” And I definitely feel that, especially with young parents, that kills me. They had a lot more to give. The loss of those people specifically has a knock-on effect that’s going to make the world worse for people for a long time. And it’s just hard to feel powerless in the face of that. And that’s where I think you have to be borderline evil to fight against a company like Neuralink or to constantly be taking pot shots at us, because what we’re doing is to try to fix that stuff. We’re trying to give people options to reduce suffering. We’re trying to take the pain out of life that broken brains brings in. And yeah, this is just our little way that we’re fighting back against entropy, I guess.
And so, what we’re doing is that. We are making a cut in the skin on the top of the head over the area of the brain that is the most potent representation of hand intentions. And so, if you are an expert concert pianist, this part of your brain is lighting up the entire time you’re playing. We call it the hand knob.
It can come in and take these tiny, much smaller than human hair, electrodes and precisely insert them into the cortex, into the surface of the brain to a very precise depth, in a very precise spot that avoids all the blood vessels that are coating the surface of the brain. And after the robot’s done with its part, then the human comes back in and puts the implant into that hole in the skull and covers it up, screwing it down to the skull and sewing the skin back together. So the whole thing is a few hours long. It’s extremely low risk compared to the average neurosurgery involving the brain that might, say, open up a deeper part of the brain or manipulate blood vessels in the brain. This opening on the surface of the brain with only cortical micro- insertions carries significantly less risk than a lot of the tumor or aneurysm surgeries that are routinely done.
Robots wouldn’t do so well in that situation, at least in their current incarnation, fully robotic surgery, like the electrode insertion portion of the neural link surgery, it goes according to a set plan. And so the humans can interrupt the flow and change the plan, but the robot can’t really change the plan midway through. It operates according to how it was programmed and how it was asked to run. It does its job very precisely, but not with a wide degree of latitude in how to react to changing conditions.
And so when I was able to practice that, it’s as close as it really reasonably should get to being the real thing in all the details, including having a mannequin body attached to this custom head. And so when we were doing the practice surgeries, we’d wheel that body into the CT scanner and take a mock CT scan and wheel it back in and conduct all the normal safety checks, verbally, “Stop. This patient we’re confirming his identification is mannequin number…” Blah, blah, blah. And then opening the brain in exactly the right spot using standard operative neuro-navigation equipment, standard surgical drills in the same OR that we do all of our practice surgeries in at Neuralink and having the skull open and have the brain pulse, which adds a degree of difficulty for the robot to perfectly precisely plan and insert those electrodes to the right depth and location. And so we kind of broke new ground on how extensively we practiced for this surgery.
And so definitely a moderate pucker factor there for the whole team not knowing if we were going to encounter, say, a degree of brain movement that was unanticipated or a degree of brain sag that took the brain far away from the skull and made it difficult to insert or some other unknown unknown problem. Fortunately everything went well and that surgery is one of the smoothest outcomes we could have imagined.
The modern version of that is to use a robot. Just like a little Kuka arm you might see building cars at the Tesla factory, this small robot arm can show you the trajectory that you intended from the pre-op MRI and establish a very rigid holder through which you can drill a small hole in the skull and pass a small rigid wire deep into that area of the brain that’s hollow, and put your electrode through that hollow wire and then remove all of that except the electrode. So you end up with the electrode very, very precisely placed far from the skull surface. Now, that’s standard technology that’s already been out in the world for a while. Neuralink right now is focused entirely on cortical targets, surface targets because there’s no trivial way to get, say, hundreds of wires deep inside the brain without doing a lot of damage. So your question, what do you see? Well, I see an MRI on a screen. I can’t see everything that DBS electrode is passing through on its way to that deep target.
And so it’s accepted with this approach that there’s going to be about one in a hundred patients who have a bleed somewhere in the brain as a result of passing that wire blindly into the deep part of the brain. That’s not an acceptable safety profile for Neuralink. We start from the position that we want this to be dramatically maybe two or three orders of magnitude safer than that, safe enough, really, that you or I, without a profound medical problem, might on our lunch break someday say, “Yeah, sure, I’ll get that. I’d been meaning to upgrade to the latest version.” And so the safety constraints given that are high, and so we haven’t settled on a final solution for arbitrarily approaching deep targets in the brain.
And so Neuralink’s approach of using highly flexible, tiny electrodes avoids a lot of the bleeding, avoids a lot of the immune response that ends up happening when rigid electrodes are pounded into the brain. And so what we see is our electrode longevity and functionality and the health of the brain tissue immediately surrounding the electrode is excellent. I mean, it goes on for years now in our animal models.
To me, it’s just really fascinating to be able to even to play with that, honestly, I would get a Neuralink just to be able to play with that, just to play with the capacity, the capability of my mind to learn this skill. It’s like learning the skill of typing and learning the skill of moving a mouse. It’s another skill of moving the mouse, not with my physical body, but with my mind.
But yeah, I think there’s cause for optimism that we might find something useful in terms of say, an implanted electrode that improves learning. Certainly there’s been some really amazing work recently from Nicholas Schiff, Jonathan Baker and others who have a cohort of patients with moderate traumatic brain injury who have had electrodes placed in the deep nucleus in the brain called the central median nucleus or just near central median nucleus, and when they apply small amounts of electricity to that part of the brain, it’s almost like electronic caffeine.
They’re able to improve people’s attention and focus. They’re able to improve how well people can perform a task. I think in one case, someone who was unable to work, after the device was turned on, they were able to get a job. And that’s sort of one of the holy grails for me with Neuralink and other technologies like this is from a purely utilitarian standpoint, can we make people able to take care of themselves and their families economically again? Can we make it so someone who’s fully dependent and even maybe requires a lot of caregiver resources, can we put them in a position to be fully independent, taking care of themselves, giving back to their communities? I think that’s a very compelling proposition and what motivates a lot of what I do and what a lot of the people at Neuralink are working for.
So on the one hand, every human that has ever lived died or will die. On the other hand, it’s just one of the hardest things to imagine inflicting on anyone that you love is having them gone. I mean, I’m sure you’ve had friends that aren’t living anymore and it’s hard to even think about them. And so I wish I had arrived at the point of nirvana where death doesn’t have a sting, I’m not worried about it. But I can at least say that I’m comfortable with the certainty of it, if not having found out how to take the tragedy out of it. When I think about my kids either not having me or me not having them or my wife.
I think people aren’t always honest with how terrifying it is. I think the more you are able to really think through it, the more terrifying it is. It’s not such a simple thing, “Oh, well, it’s the way life is.” If you really can load that in, it’s hard, but I think that’s why the Stoics did it, because it helps you get your shit together and be like, “The moment, every single moment you’re alive is just beautiful” and it’s terrifying that it’s going to end, and it’s almost like you’re shivering in the cold, a child helpless. This kind of feeling,
And then it makes you, when you have warmth, when you have the safety, when you have the love to really appreciate it. I feel like sometimes in your position when you mentioned armor just to see death, it might make you not be able to see that, the finiteness of life because if you kept looking at that, it might break you. So it is good to know that you’re kind of still struggling with that. There’s the neurosurgeon and then there’s a human, and the human is still able to struggle with that and feel the fear of that and the pain of that.
So what I’m saying is, consciousness is the sensation of some part of your brain being active, so you feel it working. You feel the part of your brain that thinks of red things or winged creatures or the taste of coffee. You feel those parts of your brain being active, the way that I’m feeling my palm being touched, and that sensory system that feels the brain working is consciousness.
For some folks, it can mean the ability just to be able to communicate again independently without needing to wear something on their face, without needing a caretaker to be able to put something in their mouth. For some folks, it can mean independence to be able to work again, to be able to navigate a computer digitally, efficiently enough to be able to get a job, to be able to support themselves, to be able to move out and ultimately be able to support themselves after their family maybe isn’t there anymore to take care of them.
And for some folks, it’s as simple as just being able to respond to their kid in time before they run away or get interested in something else. And these are deeply personal and very human problems. And what strikes me again and again when talking with these folks is that this is actually an engineering problem. This is a problem that with the right resources, with the right team, can make a lot of progress on. And at the end of the day, I think that’s a deeply inspiring message and something that makes me excited to get up every day.
And I think for the people we’re trying to help, it doesn’t matter what the complexity of the solution is as long as the problem is solved. And I want to emphasize that there can be many solutions out there that can help with these problems. And BCI is one of a collection of such solutions. So BCI in particular, I think offers several advantages here. And I think the folks that recognize this immediately are usually the people who have spinal cord injury or some form of paralysis.
Usually you don’t have to explain to them why this might be something that could be helpful. It’s usually pretty self-evident, but for the rest of us folks that don’t live with severe spinal cord injury or who don’t know somebody with ALS, it’s not often obvious why you would want a brain implant to be able to connect and navigate a computer.
And it’s surprisingly nuanced, and to the degree that I’ve learned a huge amount just working with Noland in the first Neuralink clinical trial and understanding from him and his words why this device is impactful for him, and it’s a nuanced topic. It can be the case that even if you can achieve the same thing, for example, with a mouse stick when navigating a computer, he doesn’t have access to that mouse stick every single minute of the day. He only has access when someone is available to put it in front of him. And so a BCI can really offer a level of independence and autonomy that, if it wasn’t literally physically part of your body, it’d be hard to achieve in any other way.
And I have the lucky job in that particular procedure to just be in charge of monitoring the implant. So my job is to sit there, to look at the signals coming off the implant, to look at the live brain data streaming off the device as threads are being inserted into the brain and just to basically observe and make sure that nothing is going wrong or that there’s no red flags or fault conditions that we need to go and investigate or pause the surgery to debug.
And because I had that sort of spectator view of the surgery, I had a slightly removed perspective than I think most folks in the room. I got to sit there and think to myself, “Wow, that brain is moving a lot.” When you look inside the craniectomy that we stick the threads in, one thing that most people don’t realize is the brain moves. The brain moves a lot when you breathe, your heart beats, and you can see it visibly. So that’s something that I think was a surprise to me and very, very exciting to be able to see someone’s brain who you physically know and have talked with that length, actually pausing and moving inside their skull.
If you imagine moving your arm back and forth or wiggling a pinky, this sort of signal can be present in the motor cortex. So one of the ways we start to map out what kind of signal do we actually have access to, in any particular individual’s brain, is through this task called body mapping. And body mapping is where you essentially present a visual to the user and you say, “Hey, imagine doing this,” and their visual is a 3D hand opening, closing or index finger modulating up and down.
And you ask the user to imagine that, and obviously you can’t see them do this, because they’re paralyzed, so you can’t see them actually move their arm. But while they do this task, you can record neural activity and you can basically offline model and check, “Can I predict, or can I detect the modulation corresponding with those different actions?” And so we did that task and we realized, “Hey, there’s actually some modulation associated with some of his hand motion,” which was a first indication that, “okay, we can potentially use that modulation to do useful things in the world.” For example, control a computer cursor.
And he started playing with it, the first time we showed him it. And we actually just took the same live view of his brain activity and put it in front of him and we said, “Hey, you tell us what’s going on? We’re not you. You’re able to imagine different things, and we know that it’s modulating some of these neurons, so you figure out for us, what that is actually representing.” And so he played with it for a bit. He was like, “I don’t quite get it yet.” He played for a bit longer and he said, “Oh, when I move this finger, I see this particular neuron start to fire more.”
And I said, “Okay, prove it. Do it again.” And so he said, “Okay, three, two, one,” boom. And the minute he moved, you can see instantaneously this neuron is firing, single neuron. I can tell you the exact channel number if you’re interested. It’s stuck in my brain now forever. But that single channel firing was a beautiful indication that it was behaved really modulated, neural activity, that could then be used for downstreaming tasks, like decoding a computer cursor.
I guess it visualizes you moving the hand, and there’s a very sexy polished interface that, “Hello,” I don’t know if there’s a voice component, but it just felt like when you wake up in a really nice video game, and this is the tutorial at the beginning of that video game. This is what you’re supposed to do. It’s cool.
And the other thing worth understanding about the underlying biology here, is that when neurons produce an action potential, the width of that action potential is about one millisecond. So from the start of the spike, to the end of the spike, that whole width of that characteristic feature, of a neuron firing, is one millisecond wide. And if you want to detect that an individual spike is occurring or not, you need to sample that signal, or sample the local fuel potential nearby that a neuron… Much more frequently than once a millisecond. You need to sample many, many times per millisecond, to be able to detect that this is actually the characteristic waveform of a neuron producing an action potential.
And so we sample across all 1,024 electrodes, about 20,000 times a second. 20,000 times a second means for any given one millisecond window, we have about 20 samples that tell us what that exact shape of that actual potential looks like. And once we’ve sort of sampled at super high rate the underlying electrical field nearby these cells, we can process that signal into just where do we detect a spike, or where do we not? Sort of a binary signal, one or zero. Do we detect a spike in this one millisecond or not?
And we do that because the actual information carrying subspace of neural activity, is just when our spikes occurring. Essentially everything that we care about for decoding can be captured or represented in the frequency characteristics of spike trains. Meaning, how often are spikes firing in any given window of time. And so that allows us to do sort of a crazy amount of compression, from this very rich high-density signal, to something that’s much, much more sparse and compressible, that can be sent out over a wireless radio. Like a Bluetooth communication for example.
For the engineering side of things, at least at the current scale, if the number of neurons per electrode is relatively small, you can get away with basically ignoring that problem completely. You can think of it like a random projection of neurons to electrodes, and there may be in some cases more than one neuron per electrode. But if that number is small enough, those signals can be thought of as sort of a union of the two.
And for many applications, that’s a totally reasonable trade-off to make, and can simplify the problem a lot. And as you sort of scale out channel count, the relevance of distinguishing individual neurons becomes less important. Because you have more overall signal, and you can start to rely on correlations or covariate structure in the data to help understand when that channel is firing… What does that actually represent? Because you know that when that channel’s firing in concert with these other 50 channels, that means move left. But when that same channel’s firing with concert with these other 10 channels, that means move right.
But one of these ideas is basically to build sort of like a convolutional filter almost, if you will. That slides across the signal and looks for a certain template to be matched. That template consists of how deep the spike modulates, how much it recovers, and what the duration and window of time is for that, the whole process takes. And if you can see in the signal that, that template is matched within certain bounds, then you can say, “Okay, that’s a spike.” One reason that approach is super convenient, is that you can actually implement that extremely efficiently in hardware. Which means that you can run it in low power across 1,024 channels all at once.
Another approach that we’ve recently started exploring, and this can be combined with the spike detection approach, is something called spike band power. And the benefits of that approach are that you may be able to pick up some signal from neurons that are maybe too far away to be detected as a spike, because the farther away you are from an electrode, the weaker that actual spike waveform will look like on that electrode. So you might be able to pick up population level activity of things that are maybe slightly outside the normal recording radius… What neuroscientists sometimes refer to as the hash of activity, the other stuff that’s going on. And you can look at across many channels how that background noise is behaving, and you might be able to get more juice out of the signal that way.
But it comes at a cost. That signal is now a floating point representation, which means it’s more expensive to send out over a power. It means you have to find different ways to compress it, that are different than what you can apply to binary signals. So there’s a lot of different challenges associated with these different modalities.
This is a very real possibility for a number of reasons. One is that they’ll have access to the best technology to play video games effectively. The second is they have the time to do so. So those two factors together are particularly potent for eSport competitors.
So the question is, just how much faster can you make it? And we’re already faster than what you would do if you’re going through muscle from a latency point of view, and we’re in the early stages of that. I think we can push it. So our end to end latency right now from brain spike to cursor movement, it’s about 22 milliseconds. If you think about the best mice in the world, the best gaming mice, that’s about five milliseconds ish of latency, depending on how you measure, depending how fast your screen refreshes, there’s a lot of characteristics that matter there. And the rough time for a neuron in the brain to actually impact your command of your hand is about 75 milliseconds.
So if you look at those numbers, you can see that we’re already competitive and slightly faster than what you’d get by actually moving your hand. And this is something that if you ask Noland about it, when he moved the cursor for the first time… We asked him about this, it was something I was super curious about. “What does it feel like when you’re modulating a click intention, or when you’re trying to just move the cursor to the right?” He said it moves before he is actually intending it to. Which is kind of a surreal thing, and something that I would love to experience myself one day, what is that like to have the thing just be so immediate, so fluid, that it feels like it’s happening before you’re actually intending it to move?
Another sort of important nuance to this, is that it’s not just the Neuralink itself that’s part of this equation. If you start pushing latency below the level of how fast you’re going to refresh, then you have another problem. You need your whole system to be able to be as reactive as the limits of what the technology can offer.
And so the job of the application is really to translate this wireless stream of brain data, coming off the implant, into control of the computer. And we do that by essentially building a mapping from brain activity to sort of the HID inputs, to the actual hardware. So HID is just the protocol for communicating like input device events, so for example, move mouse to this position or press this key down. And so that mapping is fundamentally what the app is responsible for. But there’s a lot of nuance of how that mapping works, and we spent a lot of time to try to get it right, and we’re still in the early stages of a long journey to figure out how to do that optimally.
So one part of that process is decoding. So decoding is this process of taking the statistical patterns of brain data, that’s being channeled across this Bluetooth connection to the application. And turning it into, for example, a mouse movement. And that decoding step, you can think of it in a couple of different parts. So similar to any machine learning problem, there’s a training step, and there’s an [inaudible 05:32:39] step. The training step in our case is a very intricate behavioral process where the user has to imagine doing different actions. So for example, they’ll be presented a screen with a cursor on it, and they’ll be asked to push that cursor to the right. Then imagine pushing that cursor to the left, push it up, push it down. And we can basically build up a pattern or using any sort of modern ML method of mapping of given this brain data, and then imagine behavior, map one to the other.
And then at test time you take that same pattern matching system. In our case it’s a deep neural network, and you run it and you take the live stream of brain data coming off their implant, you decode it by pattern matching to what you saw at calibration time, and you use that for a control of the computer. Now a couple sort of rabbit holes that I think are quite interesting. One of them has to do with how you build that best template matching system. Because there’s a variety of behavioral challenges and also debugging challenges when you’re working with someone who’s paralyzed.
Because again, fundamentally you don’t observe what they’re trying to do, you can’t see them attempt to move their hand. And so you have to figure out a way to instruct the user to do something, and validate that they’re doing it correctly, such that then you can downstream, build with confidence, the mapping between the neural spikes and the intended action.
And by doing the action correctly, what I really mean is, at this level of resolution of what neurons are doing. So if, in ideal world, you could get a signal of behavioral intent that is ground truth accurate at the scale of one millisecond resolution, then with high confidence, I could build a mapping from my neural spikes, to that behavioral intention. But the challenge is again, that you don’t observe what they’re actually doing. And so there’s a lot of nuance to how you build user experiences, that give you more than just a course on average correct representation of what the user’s intending to do.
If you want to build the world’s best mouse, you really want it to be as responsive as possible. You want it to be able to do exactly what the user’s intending, at every step along the way, not just on average be correct, when you’re trying to move it from left to right. And building a behavioral calibration game, or our software experience, that gives you that level of resolution, is what we spend a lot of time working on.
And if you think about it, there probably is, because there are enough data points in the dataset, enough constraints on your model. That there should be a way with the right sort of formulation, to let the model figure out itself, for example… At this millisecond, this is exactly how hard they’re pushing upwards, and at this millisecond, this is how hard they’re trying to push upwards.
Another competing heuristic might be, they’re actually trying to go slightly faster at the beginning of the movement and slightly slower at the end. And those competing heuristics may or may not be accurate reflections of what the user is trying to do. Another version of the task might be, “Hey, user, imagine moving this cursor a fixed offset.” So rather than follow the cursor, just try to move it exactly 200 pixels to the right. So here’s the cursor, here’s the target, okay, cursor disappears, try to move that now invisible cursor, 200 pixels to the right. And the assumption in that case would be that the user can’t actually modulate correctly that position offset.
But that position offset assumption might be a weaker assumption, and therefore potentially, you can make it more accurate, than these heuristics that are trying to guesstimate at each millisecond what the user’s trying to do. So you can imagine different tasks that make different assumptions about the nature of the user intention. And those assumptions being correct is what I would think of as a clean label.
So for example, an alternative crazy way that probably is playing a role here, is a game like WEG Grid. Where you’re just getting a very large amount of data, the person playing a game. Where if they’re in a state of flow, maybe you can get clean signal as a side effect?
There’s a lot of challenges associated with both of these techniques, and we can rabbit hole into both of them if you’re interested. But the sort of challenge with the open loop task is that the user themself doesn’t get proprioceptive feedback about what they’re doing. They don’t necessarily perceive themself or feel the mouse under their hand, when they’re trying to do an open loop calibration. They’re being asked to perform something… Imagine if you sort of had your whole right arm numbed, and you stuck it in a box and you couldn’t see it, so you had no visual feedback and you had no proprioceptive feedback, about what the position or activity of your arm was.
And now you’re asked, “Okay, given this thing on the screen, that’s moving from left to right, match that speed?” And you basically can try your best to invoke whatever that imagined action is in your brain, that’s moving the cursor from left to right. But in any situation, you’re going to be inaccurate and maybe inconsistent in how you do that task. And so that’s sort of the fundamental challenge of open loop. The challenge with closed loop is that once the user’s given a model, and they’re able to start moving the mouse on their own, they’re going to very naturally adapt to that model. And that coadaptation between the model learning what they’re doing, and the user learning how to use the model, may not find you the best sort of global minima.
And maybe that your first model was noisy in some ways, or maybe just had some quirk. There’s some part of the data distribution, it didn’t cover super well, and the user now figures out, because they’re a brilliant user like Noland, they figure out the right sequence of imagined motions, or the right angle they have to hold their hand at to get it to work. And they’ll get it to work great, but then the next day they come back to their device, and maybe they don’t remember exactly all the tricks that they used the previous day. And so there’s a complicated sort of feedback cycle here that can emerge, and can make it a very, very difficulty debugging process.
Yeah. So how do you solve it? It’s not a solve problem. That’s the first thing I want to make sure it gets across. The second thing is, any solution that involves closed loop is going to become a very difficult debugging problem. And one of my general heuristics for choosing what prompts to tackle is, that you want to choose the one that’s going to be the easiest to debug. Because if you can do that, even if the ceiling is lower, you’re going to be able to move faster, because you have a tighter iteration loop debugging the problem.
In the open loop setting, there’s not a feedback cycle to debug with the user in the loop. And so there’s some reason to think that, that should be an easier debugging problem. The other thing that’s worth understanding is that even in the closed loop setting, there’s no special software magic of how to infer what the user is truly attempting to do. In the closed loop setting, although they’re moving the cursor on the screen, they may be attempting something different than what your model is outputting. So what the model is outputting is not a signal that you can use to retrain if you want to be able to improve the model further. You still have this very complicated guestimation, or unsupervised problem of figuring out what is the true user intention underlying that signal?
And so the open loop problem has the nice property of being easy to debug, and the second nice property of, it has all the same information and content as the closed loop scenario. Another thing I want to mention and call out, is that this problem doesn’t need to be solved in order to give useful control to people. Even today with the solutions we have now, and that academia has built up over decades, the level of control that can be given to a user today, is quite useful. It doesn’t need to be solved to get to that level of control.
But again, I want to build the world’s best mouse. I want to make it so good that it’s not even a question that you want it. And to build the world’s best mouse, the superhuman version, you really need to nail that problem. And a couple maybe details of previous studies that we’ve done internally, that I think are very interesting to understand, when thinking about how to solve this problem. The first is that even when you have ground-truth data of what the user’s trying to do, and you can get this with an able-bodied monkey, a monkey that has a Neuralink device implanted, and moving a mouse to control a computer. Even with that ground-truth dataset, it turns out that the optimal thing to predict to produce high performance BCI, is not just the direct control of the mouse.
You can imagine building a dataset of what’s going on in the brain, and what is the mouse exactly doing on the table? And it turns out that if you build the mapping from neurospikes to predict exactly what the mouse is doing, that model will perform worse, than a model that is trained to predict higher level assumptions about what the user might be trying to do. For example, assuming that the monkey is trying to go in a straight line to the target, it turns out that making those assumptions is actually more effective in producing a model, than actually predicting the underlying hand movement.
In that kind of scenario, you could imagine coming up with some sort of consistency metric that you could display to the user of, “Okay, I know what the spike trend looks like on average when you do this action to the right. Maybe I can produce some sort of probabilistic estimate of how likely is that to be the action you took, given the latest trial or trajectory that you imagined?” And that could give the user some sort of feedback of how consistent are they, across different trials.
You could also imagine that if the user is prompted with that kind of consistency metric, that maybe they just become more behaviorally engaged to begin with, because the task is kind of boring when you don’t have any feedback at all. And so there may be benefits to the user experience of showing something on the screen, even if it’s not accurate. Just because it keeps the user motivated to try to increase that number, or push it upwards.
So maybe the first solution here that’s important, is that they can recalibrate whenever they want. This is something that Noland has the ability to do today, so he can recalibrate the system at 2:00 AM, in the middle of the night without his caretaker, or parents or friends around, to help push a button for him. The other important part of the solution is that when you have a good model calibrated, that you can continue using that without needing to recalibrate it. So how often he has to do this recalibration to-date, depends really on his appetite for performance.
We observe sort of a degradation through time, of how well any individual model works, but this can be mitigated behaviorally by the user adapting their control strategy. It can also be mitigated through a combination of software features that we provide to the user. For example, we let the user adjust exactly how fast the cursor is moving. We call that the gain, for example, the gain of how fast the cursor reacts to any given input intention.
They can also adjust the smoothing, how smooth the output of that cursor intention actually is. That can also adjust the friction, which is how easy is it to stop and hold still? And all these software tools allow the user a great deal of flexibility and troubleshooting mechanisms to be able to solve this problem for themselves.
And maybe one nuance of this is, even details like when you move a mouse on a MacBook trackpad, the sort of response curve of how that input that you give the trackpad translates to cursor movement is different than how it works with a mouse. When you move on the trackpad, there’s a different response function, a different curve to how much a movement translates to input to the computer than when you do it physically with a mouse. And that’s because somebody sat down a long time ago, when they’re designing the initial input systems to any computer, and they thought through exactly how it feels to use these different systems. And now we’re designing the next generation of this, input system to a computer, which is entirely done via the brain, and there’s no proprioceptive feedback, again, you don’t feel the mouse in your hand, you don’t feel the keys under your fingertips, and you want a control surface that still makes it easy and intuitive for the user to understand the state of the system, and how to achieve what they want to achieve. And ultimately the end goal is that that UX is completely… It fades in the background, it becomes something that’s so natural and intuitive that it’s subconscious to the user, and they just should feel like they have basically direct control over the cursor, just does what they want it to do. They’re not thinking about the implementation of how to make it do what they want it to do, it’s just doing what they want it to do.
One of those things is that any machine learning system that you build has some number of errors, and it matters how those errors translate to the downstream user experience. For example, if you’re developing a search algorithm in your photos, if you search for your friend, Joe, and it pulls up a photo of your friend, Josephine, maybe that’s not a big deal, because the cost of an error is not that high. In a different scenario, where you’re trying to detect insurance fraud or something like this, and you’re directly sending someone to court because of some machine learning model output, then the errors make a lot more sense to be careful about, you want to be very thoughtful about how those errors translate to downstream effects.
The same is true in BCI. So for example, if you’re building a model that’s decoding a velocity output from the brain, versus an output where you’re trying to modulate the left click for example, these have sort of different trade-offs of how precise you need to be before it becomes useful to the end user. For velocity, it’s okay to be on average correct, because the output of the model is integrated through time. So if the user’s trying to click at position A, and they’re currently position B, they’re trying to navigate over time to get between those two points. And as long as the output of the model is on average correct, they can sort of steer it through time, with the user control loop in the mix, they can get to the point they want to get to.
The same is not true of a click. For a click, you’re performing it almost instantly, at the scale of neurons firing. And so you want to be very sure that that click is correct, because a false click can be very destructive to the user. They might accidentally close the tab that they’re trying to do something in, and lose all their progress. They might accidentally hit some send button on some text that there’s only half composed and reads funny after. So there’s different sort of cost functions associated with errors in this space, and part of the UX design is understanding how to build a solution that is, when it’s wrong, still useful to the end user.
There’s many ways to measure BPS by the way, this isn’t the only way, but we present the user a grid of targets, and basically we compute a score which is dependent on how fast and accurate they can select, and then how small are the targets. And the more targets that are on the screen, the smaller they are, the more information you present per click. And so if you think about it from information theory point of view, you can communicate across different information theoretic channels, and one such channel is a typing interface, you can imagine, that’s built out of a grid, just like a software keyboard on the screen.
And bits per second is a measure that’s computed by taking the log of the number of targets on the screen. You can subtract one if you care to model a keyboard, because you have to subtract one for the delete key on the keyboard. But log of the number of targets on the screen, times the number of correct selections, minus incorrect, divided by some time window, for example, 60 seconds. And that’s sort of the standard way to measure a cursor control task in academia. And all credit in the world goes to this great professor, Dr. Shenoy of Stanford who came up with that task, and he’s also one of my inspirations for being in the field. So all the credit in the world to him for coming up with a standardized metric to facilitate this kind of bragging rights that we have now to say that Noland is the best in the world at this task with this BCI. It’s very important for progress that you have standardized metrics that people can compare across. Different techniques and approaches, how well does this do? So big kudos to him and to all the team at Stanford.
Yeah, so for Noland, and for me playing this task, there’s also different modes that you can configure this task. So the Webgrid task can be presented as just sort of a left click on the screen, or you could have targets that you just dwell over, or you could have targets that you left, right click on, you could have targets that are left, right click, middle click, scrolling, clicking and dragging. You can do all sorts of things within this general framework, but the simplest, purest form is just blue targets show up on the screen, blue means left click. That’s the simplest form of the game.
And the sort of prior records here in academic work and at Neuralink internally with NHPs have all been matched or beaten by Noland with his Neuralink device. So prior to Neuralink, the world record for a human using device is somewhere between 4.2 to 4.6 BPS, depending on exactly what paper you read and how you interpret it. Noland’s current record is 8.5 BPS. and again, this sort of median Neuralinker performance is 10 BPS. So you can think of it roughly as, he’s 85% the level of control of a median Neuralinker using their cursor to select blue targets on the screen.
I think there’s a very interesting journey ahead to get us to that same level of 10 BPS performance. It’s not the case that the tricks that got us from 4 to 6 BPS, and then 6 to 8 BPS are going to be the ones that get us from 8 to 10. And in my view, the core challenge here is really the labeling problem. It’s how do you understand, at a very, very fine resolution, what the user’s attempting to do? And I highly encourage folks in academia to work on this problem.
And so the first thing to acknowledge is that he’s extremely motivated to make this work. I’ve also had the privilege to meet other clinical trial participants from BrainGate and other trials, and they very much shared the same attitude of, they viewed this as their life’s work to advance the technology as much as they can. And if that means selecting targets on the screen for four hours from 2:00 A.M. to 6:00 A.M., then so be it. And there’s something extremely admirable about that that’s worth calling out.
Okay, so then how do you get from where he started, which is no cursor control to eight BPS? I mean, when he started, there’s a huge amount of learning to do on his side and our side to figure out what’s the most intuitive control for him. And the most intuitive control for him is, you have to find the set intersection of, “Do we have the signal to decode?” So we don’t pick up every single neuron in the motor cortex, which means we don’t have representation for every part of the body. So there may be some signals that we have better decode performance on than others. For example, on his left hand, we have a lot of difficulty distinguishing his left ring finger from his left middle finger, but on his right hand, we have a good control and good modulation detected from the neurons that were able to record for his pinky, and his thumb, and his index finger. So you can imagine how these different subspaces of modulated activity intersect with what’s the most intuitive for him.
And this has evolved over time, so once we gave him the ability to calibrate models on his own, he was able to go and explore various different ways to imagine controlling the cursor. For example, he can imagine controlling the cursor by wiggling his wrist side to side, or by moving his entire arm, by… I think at one point he did his feet. He tried a whole bunch of stuff to explore the space of what is the most natural way for him to control the cursor, that at the same time, it’s easy for us to decode-
And in those scenarios, we try, in any given session… He’ll sometimes work for eight hours a day, and so that can be hundreds of different models that we would try in that day. A lot of different things. Now, it’s also worth noting that we update the application he uses quite frequently, I think sometimes up to 4 or 5 times a day, we’ll update his application with different features, or bug fixes, or feedback that he’s given us.
He’s a very articulate person who is part of the solution, he’s not a complaining person, he says, “Hey, here’s this thing that I’ve discovered is not optimal in my flow. Here’s some ideas how to fix it. Let me know what your thoughts are, let’s figure out how to solve it.” And it often happens that those things are addressed within a couple of hours of him giving us his feedback, that’s the kind of iteration cycle we’ll have. And so sometimes at the beginning of the session, he’ll give us feedback, and at the end of the session he’s giving us feedback on the next iteration of that process or that setup.
So one of these very fun examples is scroll. So, again, manga is something he wanted to be able to read, and there’s many ways to do scroll with a BCI. You can imagine different gestures, for example, the user could do that would move the page. But scroll is a very fascinating control surface, because it’s a huge thing on the screen in front of you. So any sort of jitter in the model output, any sort of air in the model output causes an earthquake on the screen. You really don’t want to have your mango page that you’re trying to read be shifted up and down a few pixels just because your scroll decoder is not completely accurate.
And so this was an example where we had to figure out how to formulate the problem in a way that the errors of the system, whenever they do occur, and we’ll do our best to minimize them, but whenever those errors do occur, that it doesn’t interrupt the qualia, again, of the experience that the user is having. It doesn’t interrupt their flow of reading their book. And so what we ended up building is this really brilliant feature. This is a teammate named Bruce who worked on this really brilliant work called Quick Scroll. And Quick Scroll basically looks at the screen, and it identifies where on the screen are scroll bars. And it does this by deeply integrated with macOS to understand where are the scroll bars actively present on the screen, using the sort of accessibility tree that’s available to macOS apps. And we identified where those scroll bars are, and we provided a BCI scroll bar, and the BCI scroll bar looks similar to a normal scroll bar, but it behaves very differently, in that once you move over to it, your cursor sort of morphs onto it, it sort of attaches or latches onto it. And then once you push up or down, in the same way that you’d use a push to control the normal cursor, it actually moves the screen for you. So it’s basically like remapping the velocity to a scroll action.
And the reason that feels so natural and intuitive is that when you move over to attach to it feels like magnetic, so you’re sort of stuck onto it, and then it’s one continuous action, you don’t have to switch your imagined movement, you sort of snap onto it, and then you’re good to go. You just immediately can start pulling the page down or pushing it up. And even once you get that right, there’s so many little nuances of how the scroll behavior works to make it natural and intuitive. So one example is momentum. When you scroll a page with your fingers on the screen, you actually have some flow, it doesn’t just stop right when you lift your finger up. The same is true with BCI scroll, so we had to spend some time to figure out, “What are the right nuances when you don’t feel the screen under your fingertip anymore? What is the right sort of dynamic, or what’s the right amount of page give, if you will, when you push it to make it flow the right amount for the user to have a natural experience reading their book?”
I could tell you there’s so many little minutia of how exactly that scroll works, that we spent probably a month getting right, to make that feel extremely natural and easy for the user to navigate.
So we can understand, for example, that when you’re trying to close a tab, that very small, stupid little X that’s extremely tiny, which is hard to get precisely hit, if you’re dealing with a noisy output of the decoder, we can understand that that is a small little X you might be trying to hit, and actually make it a bigger target for you. Similar to how when you’re typing on your phone, if you are used to the iOS keyboard for example, it actually adapts to target size of individual keys based on an underlying language model. So it’ll actually understand if I’m typing, “Hey, I’m going to see L.” It’ll make the E key bigger because it knows Lex is the person I’m going to go see. And so that kind of predictiveness can make the experience much more smooth, even without improvements to the underlying decoder or feature detection part of the stack.
So we do that with a feature called magnetic targets, we actually index the screen, and we understand, “Okay, these are the places that are very small targets that might be difficult to hit. Here’s the kind of cursor dynamics around that location that might be indicative of the user trying to select it. Let’s make it easier. Let’s blow up the size of it in a way that makes it easier for the user to sort of snap onto that target.” So all these little details, they matter a lot in helping the user be independent in their day-to-day living.
And beyond that, it’s very, very possible, in fact, quite likely that we’ve overfit to Noland’s user experience, desires and preferences. And so what I hope to see is that when we get a second, third, fourth participant, that we find what the right wide minimums are that cover all the cases that make it more intuitive for everyone. And hopefully, there’s a crosspollination of things, where, “Oh, we didn’t think about that with this user because they can speak. But with this user who just can fundamentally not speak at all, this user experience is not optimal.” Those improvements that we make there should hopefully translate then to even people who can speak but don’t feel comfortable doing so because we’re in a public setting, like their doctor’s office.
And then at some point it was actually the modeling challenge of how do you just build a good mapping, like the supervised learning problem of, you have a bunch of data and you have a label you’re trying to predict, just what is the right neural decoder architecture and hyperparameters to optimize that? And that was the problem for a bit, and once you solve that, it became a different bottleneck. I think the next bottleneck after that was actually just software stability and reliability. If you have widely varying inference latency in your system or your app just lags out every once in a while, it decreases your ability to maintain and get in a state of flow, and it basically just disrupts your control experience. And so there’s a variety of different software bugs and improvements we made that basically increased the performance of the system, made it much more reliable, much more stable and led to a state where we could reliably collect data to build better models with.
So that was a bottleneck for a while, it was just the software stack itself. If I were to guess right now, there’s two major directions you could think about for improving VPS further. The first major direction is labeling. So labeling is, again, this fundamental challenge of given a window of time where the user is expressing some behavioral intent, what are they really trying to do at the granularity of every millisecond? And that again, is a task design problem, it’s a UX problem, it’s a machine learning problem, it’s a software problem. It touches all those different domains. The second thing you can think about to improve BPS further is either completely changing the thing you’re decoding or just extending the number of things that you’re decoding. So this is serving the direction of functionality, basically, you can imagine giving more clicks.
For example, a left click, a right click, a middle click, different actions like click-and-drag for example, and that can improve the effective bit rate of your communication processes. If you’re trying to allow the user to express themselves through any given communication channel, you can measure that with bits per second. But what actually is measured at the end of the day is how effective are they at navigating their computer? So from the perspective of the downstream tasks that you care about, functionality and extending functionality is something we’re very interested in, because not only can it improve the number of BPS, but it can also improve the downstream independence that the user has and the skill and efficiency with which they can operate their computer.
So then if the brain is representing information by changing the frequency of a neuron firing, what really matters is the delta between the baseline state of the neuron and what it looks like when it’s modulated. And what we’ve observed and what has also been observed in academic work is that that baseline rate, if you’re to target the scale, if you imagine that analogy for measuring flour or something when you’re baking, that baseline state of how much the pot weighs is actually different day to day. So if what you’re trying to measure is how much rice is in the pot, you’re going to get a different measurement different days because you’re measuring with different pots. So that baseline rate shifting is really the thing that at least from a first order description of the problem is what’s causing this downstream bias. There can be other effects, not linear effects on top of that, but at least at a very first order description of the problem. That’s what we observed day to day is that the baseline firing rate of any particular neuron or observed on a particular channel is changing.
One such explanation could be that the context effect difference between some open-loop task and some closed-loop task is much more significant with Noland than it is with the monkey. Maybe in this open-loop task, he’s watching the Lex Fridman Podcast while he’s doing the task or he’s whistling and listening to music and talking with his friend and ask his mom what’s for dinner while he’s doing this task. So the exact difference in context between those two states may be much larger and thus lead to a bigger generalization gap between the features that you’re normalizing at open-loop time and what you’re trying to use at closed-loop time.
You don’t need your caretaker to be around to set it up for you. You can activate it when you want, how you want, wherever you want. That level of independence is so game-changing for people. It means that they can text a friend at night privately without their mom needing to be in the loop. It means that they can open up and browse the internet at 2:00 AM when nobody’s around to set their iPad up for them. This is a profoundly game-changing thing for folks in that situation, and this is even before we start talking about folks that may not be able to communicate at all or ask for help when they want to. This can be potentially the only link that they have to the outside world. And yeah, that one doesn’t, I think, need explanation of why that’s so impactful.
Not all of them are equally controllable by the end user. And so it might be as simple as saying, oh, you could just add auxiliary loss terms that help you capture the thing that actually matters. But this is a very complex nuanced process. So how you turn the labels into the model is more of a nuanced process than just a standard supervised learning problem. One very fascinating anecdote here, we’ve tried many different neural network architectures that translate brain data to velocity outputs, for example. And one example that’s stuck in my brain from a couple of years ago now is at one point, we were using just fully-connected networks to decode the brain activity. We tried A-B test where we were measuring the relative performance in online control sessions of one deconvolution over the input signal. So if you imagine per channel you have a sliding window that’s producing some convolved feature, for each of those input sequences for every single channel simultaneously, you can actually get better validation metrics, meaning you’re fitting the data better and it’s generalizing better in offline data if you use this convolutional architecture. You’re reducing parameters. It’s a standard procedure when you’re dealing with time series data. Now it turns out that when using that model online, the controllability was worse, was far worse, even though the offline metrics were better, and there can be many ways to interpret that. But what that taught me at least was that, hey, it’s at least the case right now that if you were to just throw a bunch of compute at this problem and you were trying to hyperparameter optimize or let some GPT model hard code or come up with or invent many different solutions, if you were just optimizing for loss, it would not be sufficient, which means that there’s still some inherent modeling gap here. There’s still some artistry left to be uncovered here of how to get your model to scale with more compute, and that may be fundamentally a labeling problem, but there may be other components to this as well.
So one example of an interesting bug from week one of BCI with Noland was when he moved the mouse, the click signal dropped off a cliff and when he stopped, the click signal went up. So again, there’s a contamination between the two inputs. Another good example was at one point he was trying to do a left click and drag, and the minute he started moving, the left click signal dropped off a cliff. So again, ’cause some contamination between the two signals, you need to come up with some way to either in the dataset or in the model build robustness against this kind of, you think of it like overfitting, but really it’s just that the model has not seen this kind of variability before. So you need to find some way to help the model with that.
So that’s what I’m very excited about for the next year or so of clinical trial operations. On the technology side, I’m quite excited about basically everything we’re doing. I think it’s going to be awesome. The most prominent one I would say is scaling channel account. So right now we have a 1,000-channel device. The next version we’ll have between 3 and 6,000 channels, and I would expect that curve to continue in the future. And it’s unclear what set of problems will just disappear completely at that scale and what set of problems will remain and require for their focus. And so I’m excited about the clarity of gradient that gives us in terms of the user experiences we choose to focus our time and resources on. And then also in terms of even things as simple as non-stationarity, does that problem just completely go away at that scale? Or do we need to come up with new creative UXes still even at that point?
And also when we get to that time point, when we start expanding out dramatically the set of functions that you can output from one brain how to deal with all the nuances of both the user experience of not being able to feel the different keys under your fingertips, but still needing to be able to modulate all of them in synchrony to achieve the thing you want. And again, you don’t have that appropriate set of feedback loop, so how can you make that intuitive for a user to control a high dimensional control surface without feeling the thing physically? I think that’s going to be a super interesting problem. I’m also quite excited to understand do these scaling laws continue? As you scale channel count, how much further out do you go before that saturation point is truly hit?
And it’s not obvious today. I think we only know what’s in the interpolation space. We only know what’s between 0 and 1,024, but we don’t know what’s beyond that. And then there’s a whole range of interesting neuroscience and brain questions, which is, when you stick more stuff in the brain in more places, you get to learn much more quickly about what those brain regions represent. And so I’m excited about that fundamental neuroscience learning, which is also important for figuring out how to most efficiently insert electrodes in the future. So yeah, I think all those dimensions I’m really, really excited about. And that doesn’t even get close to touching the software stack that we work on every single day and what we’re working on right now.
So I think I’m very aligned with the Hitchhiker’s Guide to the Galaxy version of this question, which is basically, if we can ask the right questions, it’s much more likely we find the meaning of human existence. So in the short term as a heuristic in the search policy space, we should try to increase the diversity of people asking such questions or generally of consciousness and conscious beings asking such questions. So again, I think I will take the I don’t know card here, but say I do think there are meaningful things we can do that improve the likelihood of answering that question.
People, I don’t know if they like that I say that. It seems like I’m making light of it all, but it’s just how I am, and I don’t know. I am a very relaxed stress-free person. I rolled with the punches for a lot of this. I took it in stride. It’s like, “All right, well, what can I do next? How can I improve my life even a little bit on a day-to-day basis?” At first, just trying to find some way to heal as much of my body as possible to try to get healed, to try to get off a ventilator, learn as much as I could so I could somehow survive once I left the hospital. And then thank God I had my family around me. If I didn’t have my parents, my siblings, then I would’ve never made it this far.
They’ve done so much for me, more than I can ever thank them for, honestly, and a lot of people don’t have that. A lot of people in my situation, their families either aren’t capable of providing for them or honestly just don’t want to, and so they get placed somewhere in some sort of home. So thankfully, I had my family. I have a great group of friends, a great group of buddies from college who have all rallied around me, and we’re all still incredibly close. People always say if you’re lucky, you’ll end up with one or two friends from high school that you keep throughout your life. I have about 10 or 12 from high school that have all stuck around, and we still get together, all of us twice a year. We call it the spring series and the fall series. This last one we all did, we dressed up X-Men, so I did a-
Maybe if I got to the hospital, they’d be able to do something.When I was in the hospital right before surgery, I was trying to calm one of my friends down. I had brought her with me from college to camp, and she was just bawling over me, and I was like, “Hey, it’s going to be fine. Don’t worry.” I was cracking some jokes to try to lighten the mood. The nurse had called my mom, and I was like, “Don’t tell my mom. She’s just going to be stressed out. Call her after I’m out of surgery ’cause at least she’ll have some answers then, whether I live or not, really.” And I didn’t want her to be stressed through the whole thing, but I knew.
And then when I first woke up after surgery, I was super drugged up. They had me on fentanyl three ways, which was awesome. I don’t recommend it, but I saw some crazy stuff on that fentanyl, and it was still the best I’ve ever felt on drugs, medication, sorry, on medication. I remember the first time I saw my mom in the hospital, I was just bawling. I had ventilator in. I couldn’t talk or anything, and I just started crying because it was more like seeing her… The whole situation obviously was pretty rough, but it was just seeing her face for the first time was pretty hard. But yeah, I never had a moment of, “Man, I’m paralyzed. This sucks. I don’t want to be around anymore.” It was always just, “I hate that I have to do this, but sitting here and wallowing isn’t going to help.”
And then every now and again, it’s hard realizing things that I wanted to do in my life that I won’t be able to do anymore. I always wanted to be a husband and father, and I just don’t think that I could do it now as a quadriplegic. Maybe it’s possible, but I’m not sure I would ever put someone I love through that, having to take care of me and stuff. Not being able to go out and play sports, I was a huge athlete growing up, so that was pretty hard. Little things too, when I realized I can’t do them anymore. There’s something really special about being able to hold a book and smell a book, the feel, the texture, the smell as you turn the pages, I just love it and I can’t do it anymore, and it’s little things like that.
The two-year mark was pretty rough. Two years is when they say you will get back basically as much as you’re ever going to get back as far as movement and sensation goes. And so for the first two years, that was the only thing on my mind was try as much as I can to move my fingers, my hands, my feet, everything possible to try to get sensation and movement back. And then when the two-year mark hit, so June 30, 2018, I was really sad that that’s where I was, and then just randomly here and there, but I was never depressed for long periods of time. Just it never seemed worthwhile to me.
At some point after my accident, I realized that I might not be Job, that I might be one of his children that gets killed or kidnapped or taken from him. And so it’s about terrible things that happen to those around you who you love. So maybe in this case, my mom would be Job and she has to get through something extraordinarily hard, and I just need to try and make it as best as possible for her because she’s the one that’s really going through this massive trial.
And so I’ve always just seen the best in people around me too, and I’ve always tried to be good to people. And growing up with my mom too, she’s like the most positive energetic person in the world, and we’re all just people people. I just get along great with people. I really enjoy meeting new people, and so I just wanted to do everything. This is kind of just how I’ve been.
I think my faith had a huge part in that. I always felt like God was preparing me for something. I almost wish it wasn’t this, because I had many conversations with God about not wanting to do any of this as a quadriplegic. I told Him, “I’ll go out and talk to people. I’ll go out and travel the world and talk to stadiums, thousands of people, give my testimony. I’ll do all of it, but heal me first. Don’t make me do all of this in a chair. That sucks.” And I guess He won that argument. I didn’t really have much of a choice. I always felt like there was something going on. And to see how, I guess easily I made it through the interview process and how quickly everything happened, how the stars sort of aligned with all of this. It just told me as the surgery was getting closer, it just told me that it was all meant to happen.
It was all meant to be, and so I shouldn’t be afraid of anything that’s to come. And so I wasn’t. I kept telling myself like, “You say that now, but as soon as the surgery comes, you’re probably going to be freaking out. You’re about to have brain surgery.” And brain surgery is a big deal for a lot of people, but it’s an even bigger deal for me. It’s all I have left. The amount of times I’ve been like, “Thank You, God, that you didn’t take my brain and my personality and my ability to think, my love of learning, my character, everything. Thank You so much. As long as You left me that, then I think I can get by.” And I was about to let people go root around in there like, “Hey, we’re going to go put some stuff in your brain. Hopefully it works out.” And so it was something that gave me pause, but like I said, how smoothly everything went.
I never expected for a second that anything would go wrong. Plus the more people I met on the Barrow side and on the Neuralink side, they’re just the most impressive people in the world. I can’t speak enough to how much I trust these people with my life and how impressed I am with all of them. And to see the excitement on their faces, to walk into a room and, roll into a room and see all of these people looking at me like, “We’re so excited. We’ve been working so hard on this and it’s finally happening.” It’s super infectious and it just makes me want to do it even more. And to help them achieve their dreams, I don’t know, it’s so rewarding and I’m so happy for all of them, honestly.
But right after surgery, I was really worried that I was going to be too groggy, not all there. I had had anesthesia once before and it messed me up. I could not function for a while afterwards. And I said a lot of things that… I was really worried that I was going to start, I don’t know, dropping some bombs and I wouldn’t even know. I wouldn’t remember. So I was like, “Please God, don’t let that happen, and please let me be there enough to do this to my mom.”
And so she walked in after surgery. It was the first time they had been able to see me after surgery, and she just looked at me. She said, “Hi, how are you? How are you doing? How do you feel?” And I looked at her and this very, I think the anesthesia helped, very groggy, sort of confused look on my face. It’s like, “Who are you?” And she just started looking around the room at the surgeons, at the doctors like, “What did you do to my son? You need to fix this right now.” Tears started streaming. I saw how much she was freaking out. I was like, “I can’t let this go on.” And so I was like, “Mom, mom, I’m fine. It’s all right.” And still, she was not happy about it. She still says she’s going to get me back someday, but I mean, I don’t know. I don’t know what that’s going to look like.
So I started trying to wiggle my fingers and I just started scanning through the channels, and one of the things I was doing was moving my index finger up and down, and I just saw this yellow spike on top row, third box over or something. I saw this yellow spike every time I did it, and I was like, “Oh, that’s cool.” And everyone around me was just like, “What are you seeing?” I was like, “Look at this one. Look at this top row, third box over this yellow spike. That’s me right there, there, there.” And everyone was freaking out. They started clapping. I was like, “That’s super unnecessary.” This is what’s supposed to happen, right?
It’s not like I’m moving, but it feels like there’s a buildup of, the only way I can describe it is there are signals that aren’t getting through from my brain down, because there’s that gap in my spinal cord, so brain down, and then from my hand back up to the brain. And so it feels like those signals get stuck in whatever body part that I’m trying to move, and they just build up, and build up, and build up until they burst. And then once they burst, I get this really weird sensation of everything dissipating back out to level, and then I do it again.
It’s also just a fatigue thing, like a muscle fatigue, but without actually moving your muscles. It’s very, very bizarre. And then if you try to stare at a body part or think about a body part and move for two, three, four, sometimes eight hours, it’s very taxing on your mind. It takes a lot of focus. It was a lot easier at the beginning because I wasn’t able to control a TV in my room or anything. I wasn’t able to control any of my environment. So for the first few years, a lot of what I was doing was staring at walls. And so, obviously I did a lot of thinking and I tried to move a lot just over, and over, and over again.
It was cool to see that their technology worked and that everything that they had worked so hard for was going to pay off. But I hadn’t moved a cursor or anything at that point. I hadn’t interacted with a computer or anything at that point. So it just made sense. It was cool. I didn’t really know much about BCI at that point either, so I didn’t know what sort of step this was actually making. I didn’t know if this was a huge deal, or if this was just like, “Okay, this is, it’s cool that we got this far, but we’re actually hoping for something much better down the road.” It’s like, “Okay.” I just thought that they knew that it turned on. So I was like, “Cool, this is cool.”
That was impressive in some way. What exactly that meant, what it was hadn’t really set in for me. So again, I knew that me trying to move a body part and then that being mapped in some sort of machine learning algorithm to be able to identify my brain signals and then take that and give me cursor control, that all kind of made sense to me. I don’t know all the ins and outs of it, but I was like, “There are still signals in my brain firing. They just can’t get through because there’s a gap in my spinal cord, and so they can’t get all the way down and back up, but they’re still there.” So when I moved the cursor for the first time, I was like, “That’s cool, but I expected that that should happen.” It made sense to me. When I moved the cursor for the first time with just my mind, without physically trying to move. So I guess I can get into that just a little bit. The difference between attempted movement, and imagine movement.
Kids would think, “Uh, I guess that kind of makes sense,” and they would do it. But that’s not something we’re taught, it’s all how to do things physically. We think about thought experiments and things, but that’s not a physical action of doing things. It’s more what you would do in certain situations. So imagine movement, it never really connected with me. I guess you could maybe describe it as a professional athlete swinging a baseball bat or swinging a golf club. Imagine what you’re supposed to do. But then you go right to that and physically do it. Then you get a bat in your hand, and then you do what you’ve been imagining.
And so I don’t have that connection. So telling me to imagine something versus attempting it, there wasn’t a lot that I could do there mentally. I just kind of had to accept what was going on and try. But the attempted moving thing, it all made sense to me. If I try to move, then there’s a signal being sent in my brain, and as long as they can pick that up, then they should be able to map it to what I’m trying to do. And so when I first moved the cursor like that, it was just like, “Yes, this should happen. I’m not surprised by that.”
So there’s a delay there. And I noticed that there was something going on in my brain before I was actually attempting to move that my brain was anticipating what I wanted to do, and that all started sort of, I don’t know, percolating in my brain. It was just there always in the back like, “That’s so weird that it could do that. It kind of makes sense, but I wonder what that means as far as using the Neuralink.”
And then as I was playing around with the attempted movement and playing around with the cursor, and I saw that as the cursor control got better, that it was anticipating my movements and what I wanted it to do, like cursor movements, what I wanted it to do a bit better and a bit better. And then one day I just randomly, as I was playing Webgrid, I looked at a target before I had started attempting to move, I was just trying to get over, train my eyes to start looking ahead, like, “Okay, this is the target I’m on, but if I look over here to this target, I know I can maybe be a bit quicker getting there.”
And I looked over and the cursor just shot over. It was wild. I had to take a step back. I was like, “This should not be happening.” All day I was just smiling. I was so giddy. I was like, “Guys, do you know that this works? I can just think it and it happens.” Which they’d all been saying this entire time like, “I can’t believe you’re doing all this with your mind.” I’m like, “Yeah, but is it really with my mind. I’m attempting to move and it’s just picking that up so it doesn’t feel like it’s with my mind.” But when I moved it for the first time like that, it was, oh man. It made me think that this technology, that what I’m doing is actually way, way more impressive than I ever thought. It was way cooler than I ever thought, and it just opened up a whole new world of possibilities of what could possibly happen with this technology and what I might be able to be capable of with it.
So yeah, I’ll connect to the Link app and then go through all sorts of things, calibration for the day, maybe body mapping. I made them give me a little homework tab because I am very forgetful and I forget to do things a lot. So I have a lot of data collection things that they want me to do.
So if I do calibration for 45 minutes, the first 15 minutes, I can’t use imagined movement. It just doesn’t work for some reason. And after a certain point, I can just feel it, I can tell. It moves different. That’s the best way I can describe it. It’s almost as if it is anticipating what I am going to do again, before I go to do it. And so using attempted movement for 15 minutes, at some point, I can tell when I move my eyes to the next target that the cursor is starting to pick up. It’s starting to understand, it’s learning what I’m going to do.
One thing I have asked them, and something that I really enjoy striving for, is towards the end of calibration, there is a time between targets. And so I like to keep, at the end, that number as low as possible. So at the beginning it can be four or five, six seconds between me popping bubbles, but towards the end I like to keep it below 1.5 or if I could get it to one second between bubbles. Because in my mind, that translates really nicely to something like Webgrid, where I know if I can hit a target, one every second, that I’m doing real, real well.
I thought it would’ve been a cruel twist of fate if I had gotten to see the view from the top of this mountain and then have it all come crashing down after a month. And I knew, I say the top of the mountain, but how I saw it was I was just now starting to climb the mountain and there was so much more that I knew was possible. And so to have all of that be taken away was really, really hard. But then on the drive over to the facility, I don’t know, five minute drive, whatever it is, I talked with my parents about it. I prayed about it. I was just like, I’m not going to let this ruin my day. I’m not going to let this ruin this amazing tour that they have set up for me. I want to go show everyone how much I appreciate all the work they’re doing.
I want to go meet all of the people who have made this possible, and I want to go have one of the best days of my life, and I did. And it was amazing, and it absolutely was one of the best days I’ve ever been privileged to experience. And then for a few days I was pretty down in the dumps, but for the first few days afterwards, I didn’t know if it was ever going to work again. And then I made the decision that, even if I lost the ability to use the Neuralink, even if I lost out on everything to come, if I could keep giving them data in any way, then I would do that.
If I needed to just do some of the data collection every day or body mapping every day for a year, then I would do it because I know that everything I’m doing helps everyone to come after me, and that’s all I wanted. Just the whole reason that I did this was to help people, and I knew that anything I could do to help, I would continue to do, even if I never got to use the cursor again, then I was just happy to be a part of it. And everything that I had done was just a perk. It was something that I got to experience, and I know how amazing it’s going to be for everyone to come after me. So might as well just keep trucking along.
So what we care about ultimately is that you can use it independently to do whatever you want. And to get to that point, it required us to re-engineer the UX, as you talked about with the dwell cursor, to make it something that you can use independently without us needing to be involved all the time. And yeah, this is obviously the start of this journey still. Hopefully we get back to the places where you’re doing multiple clicks and using that to control, much more fluidly, everything, and much more naturally the applications that you’re trying to interface with.
They’re going to think of improvements something like, wow, that’s a really good idea. I wish I would’ve thought of that. And then they’re also going to give me some pushback about, yeah, what you are asking them to do here, that’s a bad idea. Let’s do it this way. And I’m more than happy to have that happen, but it’s just a lot of different interactions with different games or applications, the internet, just with the computer in general. There’s tons of bugs that end up popping up, left, right, center.
So it’s just me trying to use it as much as possible and showing them what works and what doesn’t work, and what I would like to be better. And then they take that feedback and they usually create amazing things for me. They solve these problems in ways I would’ve never imagined. They’re so good at everything they do, and so I’m just really thankful that I’m able to give them feedback and they can make something of it, because a lot of my feedback is really dumb. It’s just like, “I want this, please do something about it,” and it’ll come back, super well-thought-out, and it’s way better than anything I could have ever thought of or implemented myself. So they’re just great. They’re really, really cool.
And then after that, I go click on it, go back into Webgrid, and I’m like, “All right, that means I have 10 minutes left before this thing’s dead.” That’s what’s going on in my head, generally. That and whatever song’s playing. And I want to break those records so bad. It’s all I want when I’m playing Webgrid. It has become less of like, “Oh, this is just a leisurely activity. I just enjoy doing this because it just feels so nice and it puts me at ease.” It is, “No. Once I’m in Webgrid, you better break this record or you’re going to waste five hours of your life right now.” And I don’t know. It’s just fun. It’s fun, man.
And then also, there are a lot of different disabilities that all originate in the brain, and you would be able to hopefully be able to solve a lot of those. I know there’s already stuff to help people with seizures that can be implanted in the brain. I imagine the same thing. And so you could do something like that. I know that even someone like Joe Rogan has talked about the possibilities with being able to stimulate the brain in different ways. I’m not sure how ethical a lot of that would be. That’s beyond me, honestly. But I know that there is a lot that can be done when we’re talking about the brain and being able to go in and physically make changes to help people or to improve their lives. So I’m really looking forward to everything that comes from this. And I don’t think it’s all that far off. I think a lot of this can be implemented within my lifetime, assuming that I live a long life.
But being able to interact with the world physically, that would just be amazing. And not just for having it be a caretaker or something, but something like I talked about. Just being able to read a book. Imagine an Optimus robot just being able to hold a book open in front of me. I get that smell again. I might not be able to feel it at that point, or maybe I could, again, with the sensation and stuff. But there’s something different about reading a physical book than staring at a screen or listening to an audiobook. I actually don’t like audiobooks. I’ve listened to a ton of them at this point, but I don’t really like them. I would much rather read a physical copy.
And he said, if anything, seeing me go through this accident, he believes that there isn’t a God. And it’s a very different reaction, but I believe that it is a way for God to test us, to build our character, to send us through trials and tribulations, to make sure that we understand how precious He is and the things that He’s given us and the time that He’s given us, and then to hopefully grow from all of that. I think that’s a huge part of being here, is to not just have an easy life and do everything that’s easy, but to step out of our comfort zones and really challenge ourselves because I think that’s how we grow.
I’ve always been a people person and I love learning about people, and I love learning how people developed and where they came from, and to see how much people are willing to do for someone like me when they don’t have to, and they’re going out of their way to make my life better. It gives me a lot of hope for just humanity in general, how much we care and how much we’re capable of when we all get together and try to make a difference. And I know there’s a lot of bad out there in the world, but there always has been and there always will be. And I think that that is… It shows human resiliency and it shows what we’re able to endure and how much we just want to be there and help each other, and how much satisfaction we get from that, because I think that’s one of the reasons that we’re here is just to help each other, and… I don’t know. That always gives me hope, is just realizing that there are people out there who still care and who want to help.

Introduction
Lex Fridman
The following is a conversation with Elon Musk, DJ Seo, Matthew MacDougall, Bliss Chapman, and Noland Arbaugh about Neuralink and the future of humanity. Elon, DJ, Matthew and Bliss are of course part of the amazing Neuralink team, and Noland is the first human to have a Neuralink device implanted in his brain. I speak with each of them individually, so use timestamps to jump around, or as I recommend, go hardcore, and listen to the whole thing. This is the longest podcast I’ve ever done. It’s a fascinating, super technical, and wide-ranging conversation, and I loved every minute of it. And now, dear friends, here’s Elon Musk, his fifth time on this, the Lex Fridman podcast,

How quickly do you think the number of human participants will scale?
How quickly do you think the number of human participants will scale?
Elon Musk
It depends somewhat on the regulatory approval, the rate at which we get regulatory approvals. So, we’re hoping to do 10 by the end of this year, total of 10. So, eight more.

Lex Fridman
And with each one, you’re going to be learning a lot of lessons about the neurobiology of the brain, everything. The whole chain of the Neuralink, the decoding, the signal processing, all that kind of stuff.

Elon Musk
Yeah. Yeah. I think it’s obviously going to get better with each one. I don’t want to jinx it, but it seems to have gone extremely well with the second implant. So, there’s a lot of signal, a lot of electrodes. It’s working very well.
Yeah. Yeah. I think it’s obviously going to get better with each one. I don’t want to jinx it, but it seems to have gone extremely well with the second implant. So, there’s a lot of signal, a lot of electrodes. It’s working very well.

What improvements do you think we’ll see in Neuralink in the coming, let’s say, let’s get crazy, the coming years.
What improvements do you think we’ll see in Neuralink in the coming, let’s say, let’s get crazy, the coming years.
Elon Musk
In years, it’s going to be gigantic, because we’ll increase the number of electrodes dramatically. We’ll improve the signal processing. So, even with only roughly, I don’t know, 10, 15% of the electrodes working with Noland, with our first patient, we were able to get to achieve a bit per second. That’s twice the world record. So, I think we’ll start vastly exceeding the world record by orders of magnitude in the years to come. So, start getting to, I don’t know, 100 bits per second, thousand. Maybe if five years from now, we might be at a megabit, faster than any human could possibly communicate by typing, or speaking.

Telepathy
Lex Fridman
Yeah. That BPS is an interesting metric to measure. There might be a big leap in the experience once you reach a certain level of BPS.

Do you think they’ll improve the quality of intellectual discourse?
Do you think they’ll improve the quality of intellectual discourse?
Elon Musk
Well, I think you could think of it, if you were to slow down communication, how do you feel about that? If you’d only talk at, let’s say one-tenth of normal speed, you’d be like, “Wow, that’s agonizingly slow.”

Yeah.
Yeah.
Elon Musk
So, now imagine you could communicate clearly at 10, or 100, or 1,000 times faster than normal.
So, now imagine you could communicate clearly at 10, or 100, or 1,000 times faster than normal.
Lex Fridman
Listen, I’m pretty sure nobody in their right mind listens to me at 1X. they listen at 2X. I can only imagine what 10X would feel like, or I could actually understand it.
Listen, I’m pretty sure nobody in their right mind listens to me at 1X. they listen at 2X. I can only imagine what 10X would feel like, or I could actually understand it.
Elon Musk
I usually default to 1.5X. You can do 2X. Well actually, if I’m listening to somebody get to… in 15, 20 minutes, I want to go to sleep, then I’ll do it 1.5X. If I’m paying attention, I’ll do 2X.

Right.
Elon Musk
But actually, if you actually listen to podcasts, or audiobooks or anything at… If you get used to doing it at 1.5, then one sounds painfully slow.

I’m still holding onto one, because I’m afraid, I’m afraid of myself becoming bored with the reality, with the real world, where everyone’s speaking in 1X.

Elon Musk
Well, it depends on the person. You can speak very fast. Like we can communicate very quickly. And also, if you use a wide range of… if your vocabulary is larger, your effective bit rate is higher.

Lex Fridman
That’s a good way to put it.
That’s a good way to put it.
Elon Musk
Yeah.
Yeah.
Lex Fridman
The effective bit rate. That is the question, is how much information is actually compressed in the low bit transfer of language?
The effective bit rate. That is the question, is how much information is actually compressed in the low bit transfer of language?
Elon Musk
Yeah. If there’s a single word that is able to convey something that would normally require, I don’t know, 10 simple words, then you’ve got maybe a 10X compression on your hands. And that’s really like with memes. Memes are like data compression. You’re simultaneously hit with a wide range of symbols that you can interpret, and you get it faster than if it were words, or a simple picture.
Yeah. If there’s a single word that is able to convey something that would normally require, I don’t know, 10 simple words, then you’ve got maybe a 10X compression on your hands. And that’s really like with memes. Memes are like data compression. You’re simultaneously hit with a wide range of symbols that you can interpret, and you get it faster than if it were words, or a simple picture.
Lex Fridman
And of course, you’re referring to memes broadly like ideas.
And of course, you’re referring to memes broadly like ideas.
Elon Musk
Yeah. There’s an entire idea structure that is like an idea template, and then you can add something to that idea template. But somebody has that pre-existing idea template in their head. So, when you add that incremental bit of information, you’re conveying much more than if you just said a few words. It’s everything associated with that meme.
Yeah. There’s an entire idea structure that is like an idea template, and then you can add something to that idea template. But somebody has that pre-existing idea template in their head. So, when you add that incremental bit of information, you’re conveying much more than if you just said a few words. It’s everything associated with that meme.
Lex Fridman
You think there’ll be emergent leaps of capability as you scale the number of electrodes?
You think there’ll be emergent leaps of capability as you scale the number of electrodes?
Elon Musk
Yeah.
Yeah.
Lex Fridman
Do you think there’ll be an actual number where just the human experience will be altered?
Do you think there’ll be an actual number where just the human experience will be altered?
Elon Musk
Yes.
Yes.
Lex Fridman
What do you think that number might be? Whether electrodes, or BPS? We of course, don’t know for sure, but is this 10,000, 100,000?
What do you think that number might be? Whether electrodes, or BPS? We of course, don’t know for sure, but is this 10,000, 100,000?
Elon Musk
Yeah. Certainly, if you’re anywhere at 10,000 bits per second, that’s vastly faster than any human can communicate right now. If you think what is the average bits per second of a human, it is less than one bit per second over the course of a day. Because there are 86,400 seconds in a day, and you don’t communicate 86,400 tokens in a day. Therefore, your bits per second is less than one, averaged over 24 hours. It’s quite slow.
Yeah. Certainly, if you’re anywhere at 10,000 bits per second, that’s vastly faster than any human can communicate right now. If you think what is the average bits per second of a human, it is less than one bit per second over the course of a day. Because there are 86,400 seconds in a day, and you don’t communicate 86,400 tokens in a day. Therefore, your bits per second is less than one, averaged over 24 hours. It’s quite slow.
And now, even if you’re communicating very quickly, and you’re talking to somebody who understands what you’re saying, because in order to communicate, you have to at least to some degree, model the mind state of the person to whom you’re speaking. Then take the concept you’re trying to convey, compress that into a small number of syllables, speak them, and hope that the other person decompresses them into a conceptual structure that is as close to what you have in your mind as possible.
Lex Fridman
Yeah. There’s a lot of signal loss there in that process.
Yeah. There’s a lot of signal loss there in that process.
Elon Musk
Yeah. Very lossy, compression, and decompression. And a lot of what your neurons are doing is distilling the concepts down to a small number of symbols, or say syllables that I’m speaking, or keystrokes, whatever the case may be. So, that’s a lot of what your brain computation is doing. Now, there is an argument that that’s actually a healthy thing to do, or a helpful thing to do because as you try to compress complex concepts, you’re perhaps forced to distill what is most essential in those concepts, as opposed to just all the fluff. So, in the process of compression, you distill things down to what matters the most, because you can only say a few things.

So, in the process of compression, you distill things down to what matters the most, because you can only say a few things.
So that is perhaps helpful. I think we’ll probably get… If our data rate increases, it’s highly probable it will become far more verbose. Just like your computer, when computers had… My first computer had 8K of RAM, so you really thought about every byte. And now you’ve got computers with many gigabytes of RAM. So, if you want to do an iPhone app that just says, “Hello world,” it’s probably, I don’t know, several megabytes minimum, a bunch of fluff. But nonetheless, we still prefer to have the computer with the more memory and more compute.
So, the long-term aspiration of Neuralink is to improve the AI human symbiosis by increasing the bandwidth of the communication. Because even if… In the most benign scenario of AI, you have to consider that the AI is simply going to get bored waiting for you to spit out a few words. If the AI can communicate at terabits per second, and you’re communicating at bits per second, it’s like talking to a tree.
Power of human mind
Lex Fridman
Well, it is a very interesting question for a super intelligent species, what use are humans?
Well, it is a very interesting question for a super intelligent species, what use are humans?
Elon Musk
I think there is some argument for humans as a source of will.
I think there is some argument for humans as a source of will.
Lex Fridman
Will?
Will?
Elon Musk
Will, yeah. Source of will, or purpose. So if you consider the human mind as being… Essentially there’s the primitive, limbic elements, which basically even reptiles have. And there’s the cortex, the thinking and planning part of the brain. Now, the cortex is much smarter than the limbic system, and yet is largely in service to the limbic system. It’s trying to make the limbic system happy. The sheer amount of compute that’s gone into people trying to get laid is insane, without actually seeking procreation. They’re just literally trying to do this simple motion, and they get a kick out of it. So, this simple, which in the abstract, rather absurd motion, which is sex, the cortex is putting a massive amount of compute into trying to figure out how to do that.

So, this simple, which in the abstract, rather absurd motion, which is sex, the cortex is putting a massive amount of compute into trying to figure out how to do that.
Lex Fridman
So like 90% of distributed compute of the human species is spent on trying to get laid, probably. A large percentage.
So like 90% of distributed compute of the human species is spent on trying to get laid, probably. A large percentage.
Elon Musk
A massive amount. Yes. Yeah. Yeah. There’s no purpose to most sex except hedonistic. It’s a sort of joy, or whatever, dopamine release. Now, once in a while, it’s procreation, but for modern humans, it’s mostly recreational. And so, your cortex, much smarter than your limbic system, is trying to make the limbic system happy, because the limbic system wants to have sex, or wants some tasty food, or whatever the case may be.
A massive amount. Yes. Yeah. Yeah. There’s no purpose to most sex except hedonistic. It’s a sort of joy, or whatever, dopamine release.

And so, your cortex, much smarter than your limbic system, is trying to make the limbic system happy, because the limbic system wants to have sex, or wants some tasty food, or whatever the case may be.
And then that is then further augmented by the tertiary system, which is your phone, your laptop, iPad, whatever, all your computing stuff. That’s your tertiary layer. So, you’re actually already a cyborg. You have this tertiary compute layer, which is in the form of your computer with all the applications, or your compute devices. And so, in the getting laid front, there’s actually a massive amount of digital compute also trying to get laid, with Tinder and whatever.
Lex Fridman
Yeah. So, the compute that we humans have built is also participating.
Yeah. So, the compute that we humans have built is also participating.
Elon Musk
Yeah. There’s like gigawatts of compute going into getting laid, of digital compute.
Yeah. There’s like gigawatts of compute going into getting laid, of digital compute.
Lex Fridman
Yeah. What if AGI was-
Yeah. What if AGI was-
Elon Musk
This is happening as we speak.
This is happening as we speak.
Lex Fridman
… if we merge with AI, it’s just going to expand the compute that we humans use-
… if we merge with AI, it’s just going to expand the compute that we humans use-

Yeah.
Yeah.
Elon Musk
But what I’m saying is that, yes, is there a use for humans? Well, there’s this fundamental question of what’s the meaning of life? Why do anything at all? And so, if our simple limbic system provides a source of will to do something, that then goes through our cortex, that then goes to our tertiary compute layer, then I don’t know, it might actually be that the AI, in a benign scenario, is simply trying to make the human limbic system happy.

Lex Fridman
Yeah. It seems like the will is not just about the limbic system. There’s a lot of interesting, complicated things in there. We also want power.

As a group of humans, when we get together, we start to have this kind of collective intelligence that is more complex in its will than the underlying individual descendants of apes, right?

Yeah. There are these fairly cerebral, or higher level goals. For me, it’s like, what’s the meaning of life, or understanding the nature of the universe, is of great interest to me, and hopefully to the AI. And that’s the mission of xAI and Grok is understand the universe.

Future of Neuralink
Lex Fridman
So do you think people… When you have a Neuralink with 10,000, 100,000 channels, most of the use cases will be communication with AI systems?
So do you think people… When you have a Neuralink with 10,000, 100,000 channels, most of the use cases will be communication with AI systems?
Elon Musk
Well, assuming that there are not… They’re solving basic neurological issues that people have. If they’ve got damaged neurons in their spinal cord, or neck, as is the case with our first two patients, then obviously the first order of business is solving fundamental neuron damage in a spinal cord, neck, or in the brain itself. So, our second product is called Blindsight, which is to enable people who are completely blind, lost both eyes, or optic nerve, or just can’t see at all, to be able to see by directly triggering the neurons in the visual cortex.

So we’re just starting at the basics here, so it’s the simple stuff, relatively speaking, is solving neuron damage. It can also solve I think probably schizophrenia, if people have seizures of some kind, it could probably solve that. It could help with memory. So, there’s kind of a tech tree, if you will. You’ve got the basics. You need literacy before you can have Lord of the Rings.
Lex Fridman
Got it.
Got it.
Elon Musk
So, do you have letters and the alphabet? Okay, great. Words? And then eventually you get sagas. So, I think there may be some things to worry about in the future, but the first several years are really just solving basic neurological damage, like for people who have essentially complete or near complete loss from the brain to the body, like Stephen Hawking would be an example, the Neuralink would be incredibly profound, because you can imagine if Stephen Hawking could communicate as fast as we’re communicating, perhaps faster. And that’s certainly possible. Probable, in fact. Likely, I’d say.

So there’s a kind of dual track of medical and non-medical, meaning so everything you’ve talked about could be applied to people who are non-disabled in the future?

Lex Fridman
Yes.
Yes.
Elon Musk
Because there’s obviously some risk with a new device. You can’t get the risk down to zero, it’s not possible. So, you want to have the highest possible reward, given there’s a certain irreducible risk. And if somebody’s able to have a profound improvement in their communication, that’s worth the risk.

Elon Musk
Yeah. As you get the risk down. And once the risk is down to… If you have thousands of people that have been using it for years and the risk is minimal, then perhaps at that point you could consider saying, “Okay, let’s aim for augmentation.” Now, I think we’re actually going to aim for augmentation with people who have neuron damage. So we’re not just aiming to give people the communication data rate equivalent to normal humans. We’re aiming to give people who have… A quadriplegic, or maybe have complete loss of the connection to the brain and body, a communication data rate that exceeds normal humans. While we’re in there, why not? Let’s give people superpowers.

And the same for vision. As you restore vision, there could be aspects of that restoration that are superhuman.
And the same for vision. As you restore vision, there could be aspects of that restoration that are superhuman.
Elon Musk
Yeah. At first, the vision restoration will be low res, because you have to say, “How many neurons can you put in there, and trigger?” And you can do things where you adjust the electric field. So, even if you’ve got, say 10,000 neurons, it’s not just 10,000 pixels, because you can adjust the field between the neurons, and do them in patterns in order to have say, 10,000 electrodes, effectively give you, I don’t know, maybe like having a megapixel, or a 10 megapixel situation. And then over time, I think you get to higher resolution than human eyes. And you could also see in different wavelengths. So, like Geordi La Forge from Star Trek, he had the thing. Do you want to see it in radar? No problem. You could see ultraviolet, infrared, eagle vision, whatever you want.

I guess that is the question for non-disabled people. Do you think that there’s a lot in our perception, in our experience of the world that could be explored, that could be played with, using Neuralink?
Elon Musk
Yeah, I mean, Neuralink, it’s really a generalized input-output device. It’s reading electrical signals, and generating electrical signals, and I mean, everything that you’ve ever experienced in your whole life, smell, emotions, all of those are electrical signals. So, it’s kind of weird to think that your entire life experience is distilled down to electrical signals for neurons, but that is in fact the case. Or I mean, that’s at least what all the evidence points to. So, I mean, if you trigger the right neuron, you could trigger a particular scent. You could certainly make things glow. I mean, do pretty much anything. I mean, really, you can think of the brain as a biological computer. So, if there are certain say, chips or elements of that biological computer that are broken, let’s say your ability to… If you’ve got a stroke, that if you’ve had a stroke, that means some part of your brain is damaged. Let’s say it’s speech generation, or the ability to move your left hand. That’s the kind of thing that a Neuralink could solve.

If you’ve got a massive amount of memory loss that’s just gone, well, we can’t get the memories back. We could restore your ability to make memories, but we can’t restore memories that are fully gone. Now, I should say, maybe if part of the memory is there, and the means of accessing the memory is the part that’s broken, then we could re-enable the ability to access the memory. But you can think of it like ram in a computer, if the ram is destroyed, or your SD card is destroyed, we can’t get that back. But if the connection to the SD card is destroyed, we can fix that. If it is fixable physically, then it can be fixed.

Yeah. Well, I mean, what are we but our memories? And what is death? But the loss of memory, loss of information? If you could say, well, if you could run a thought experiment, what if you were disintegrated painlessly, and then reintegrated a moment later, like teleportation, I guess? Provided there’s no information loss, the fact that your one body was disintegrated is irrelevant.

Merging with AI

Elon Musk
It’s an idea that may help with AI safety. Certainly, I wouldn’t want to claim it’s some panacea, or that it’s a sure thing, but I mean, many years ago I was thinking like, “Well, what would inhibit alignment of collective human will with artificial intelligence?” And the low data rate of humans, especially our slow output rate would necessarily, just because the communication is so slow, would diminish the link between humans and computers. The more you are a tree, the less you know what the tree is. Let’s say you look at this plant or whatever, and hey, I’d really like to make that plant happy, but it’s not saying a lot.

Yeah. We could better align collective human will with AI if the output rate especially was dramatically increased. And I think there’s potential to increase the output rate by, I don’t know, three, maybe six, maybe more orders of magnitude. So, it’s better than the current situation.

And that output rate would be by increasing the number of electrodes, number of channels, and also maybe implanting multiple Neuralinks?

Yeah. If it’s extremely safe, and you can have superhuman abilities, and let’s say you can upload your memories, so you wouldn’t lose memories, then I think probably a lot of people would choose to have it. It would supersede the cell phone, for example. I mean, the biggest problem that say, a phone has, is trying to figure out what you want. That’s why you’ve got auto complete, and you’ve got output, which is all the pixels on the screen, but from the perspective of the human, the output is so frigging slow. Desktop or phone is desperately just trying to understand what you want. And there’s an eternity between every keystroke from a computer standpoint.

Elon Musk
I mean, they all matter. It’s sort of like saying, let’s say it’s a Formula 1 race, what matters more, the car or the driver? I mean, they both matter. If a car is not fast, then if, let’s say, it’s half the horsepower of your competitors, the best driver will still lose. If it’s twice the horsepower, then probably even a mediocre driver will still win. So, the training compute is kind of like the engine, this horsepower of the engine. So, really, you want to try to do the best on that. And then, it’s how efficiently do you use that training compute, and how efficiently do you do the inference, the use of the AI? So, obviously, that comes down to human talent. And then, what unique access to data do you have? That also plays a role.

Do you think Twitter data will be useful?
Elon Musk
Yeah. I mean, I think most of the leading AI companies have already scraped all the Twitter data. Not I think. They have. So, on a go forward basis, what’s useful is the fact that it’s up to the second, because that’s hard for them to scrape in real time. So, there’s an immediacy advantage that Grok has already. I think with Tesla and the real time video coming from several million cars, ultimately tens of millions of cars with Optimus, there might be hundreds of millions of Optimus robots, maybe billions, learning a tremendous amount from the real world. That’s the biggest source of data, I think, ultimately, is Optimus, probably. Optimus is going to be the biggest source of data.

Did it spill water or not? Simple stuff like that. But it can do that at scale times a billion, so generate useful data from reality, so cause and effect stuff.

What do you think it takes to get to mass production of humanoid robots like that?
What do you think it takes to get to mass production of humanoid robots like that?
Elon Musk
It’s the same as cars, really. I mean, global capacity for vehicles is about 100 million a year, and it could be higher. It’s just that the demand is on the order of 100 million a year. And then, there’s roughly two billion vehicles that are in use in some way, which makes sense because the life of a vehicle is about 20 years. So, at steady state, you can have 100 million vehicles produced a year with a two billion vehicle fleet, roughly. Now, for humanoid robots, the utility is much greater. So, my guess is humanoid robots are more like at a billion plus per year.

The sensory control homunculus is where you have humongous hands. So I mean, your hands, the actuators, the muscles of your hand are almost overwhelmingly in your forearm. So, your forearm has the muscles that actually control your hand. There’s a few small muscles in the hand itself, but your hand is really like a skeleton meat puppet and with cables. So, the muscles that control your fingers are in your forearm, and they go through the carpal tunnel, which is that you’ve got a little collection of bones and a tiny tunnel that these cables, the tendons go through, and those tendons are mostly what move your hands.

Giant hands?
Giant hands?
Elon Musk
… yeah, giant hands that look weird. And then, they don’t actually have enough degrees of freedom or enough strength. So then you realize, “Oh, okay, that’s why you got to put the actuators in the forearm.” And just like a human, you’ve got to run cables through a narrow tunnel to operate the fingers. And then, there’s also a reason for not having all the fingers the same length. So, it wouldn’t be expensive from an energy or evolutionary standpoint to have all your fingers be the same length. So, why not do the same length?

So, as you’re figuring out this problem, you have to also figure out a way to do it so you can mass manufacture it, so as to be as simple as possible.
Elon Musk
It’s actually going to be quite complicated. The as possible part is it’s quite a high bar. If you want to have a humanoid robot that can do things that a human can do, actually, it’s a very high bar. So, our new arm has 22 degrees of freedom instead of 11 and has, like I said, the actuators in the forearm. And all the actuators are designed from scratch, from physics first principles. The sensors are all designed from scratch. And we’ll continue to put a tremendous amount of engineering effort into improving the hand. By hand, I mean the entire forearm, from elbow forward, is really the hand. So, that’s incredibly difficult engineering, actually. And so, the simplest possible version of a humanoid robot that can do even most, perhaps not all, of what a human can do is actually still very complicated. It’s not simple. It’s very difficult.

Elon’s approach to problem-solving
Lex Fridman
Can you just speak to what it takes for a great engineering team for you? What I saw in Memphis, the supercomputer cluster, is just this intense drive towards simplifying the process, understanding the process, constantly improving it, constantly iterating it.
Can you just speak to what it takes for a great engineering team for you? What I saw in Memphis, the supercomputer cluster, is just this intense drive towards simplifying the process, understanding the process, constantly improving it, constantly iterating it.
Elon Musk
Well, it’s easy to say ‘simplify,’ and it’s very difficult to do it. I have this very basic first principles algorithm that I run kind of as a mantra, which is to first question the requirements, make the requirements less dumb. The requirements are always dumb to some degree. So, you want to start off by reducing the number of requirements, and no matter how smart the person is who gave you those requirements, they’re still dumb to some degree. You have to start there, because, otherwise, you could get the perfect answer to the wrong question. So, try to make the question the least wrong possible. That’s what question the requirements means.

You have to start there, because, otherwise, you could get the perfect answer to the wrong question. So, try to make the question the least wrong possible. That’s what question the requirements means.
And then, the second thing is try to delete whatever the step is, the part or the process step. It sounds very obvious, but people often forget to try deleting it entirely. And if you’re not forced to put back at least 10% of what you delete, you’re not deleting enough. Somewhat illogically, people often, most of the time, feel as though they’ve succeeded if they’ve not been forced to put things back in. But, actually, they haven’t because they’ve been overly conservative and have left things in there that shouldn’t be. And only the third thing is try to optimize it or simplify it. Again, these all sound, I think, very obvious when I say them, but the number of times I’ve made these mistakes is more than I care to remember. That’s why I have this mantra. So in fact, I’d say the most common mistake of smart engineers is to optimize a thing that should not exist.
Lex Fridman
Right. So, like you say, you run through the algorithm and basically show up to a problem, show up to the supercomputer cluster, and see the process, and ask, “Can this be deleted?”
Right. So, like you say, you run through the algorithm and basically show up to a problem, show up to the supercomputer cluster, and see the process, and ask, “Can this be deleted?”
Elon Musk
Yeah. First try to delete it. Yeah.
Yeah. First try to delete it. Yeah.
Lex Fridman
Yeah. That’s not easy to do.
Yeah. That’s not easy to do.
Elon Musk
No. Actually, what generally makes people uneasy is that at least some of the things that you delete, you will put back in. But going back to sort of where our limbic system can steer us wrong is that we tend to remember, with sometimes a jarring level of pain, where we deleted something that we subsequently needed. And so, people will remember that one time they forgot to put in this thing three years ago, and that caused them trouble. And so, they overcorrect, and then they put too much stuff in there and overcomplicate things. So, you actually have to say, “Look, we’re deliberately going to delete more than we should.” At least one in 10 things, we’re going to add back in.

Lex Fridman
Everybody feels a little bit of the pain.
Everybody feels a little bit of the pain.
Elon Musk
Absolutely. And I tell them in advance, “Yeah, some of the things that we delete, we’re going to put back in.” People get a little shook by that, but it makes sense because if you’re so conservative as to never have to put anything back in, you obviously have a lot of stuff that isn’t needed. So, you got to overcorrect. This is, I would say, like a cortical override to a limbic instinct.

One of many that probably leads us astray.
One of many that probably leads us astray.
Elon Musk
Yeah. There’s a step four as well, which is any given thing can be sped up. However fast you think it can be done, whatever the speed it’s being done, it can be done faster. But you shouldn’t speed things up until you’ve tried to delete it and optimize. Although, you’re speeding up something that… Speeding up something that shouldn’t exist is absurd.
Yeah. There’s a step four as well, which is any given thing can be sped up. However fast you think it can be done, whatever the speed it’s being done, it can be done faster. But you shouldn’t speed things up until you’ve tried to delete it and optimize. Although, you’re speeding up something that… Speeding up something that shouldn’t exist is absurd.
And then, the fifth thing is to automate it. I’ve gone backwards so many times where I’ve automated something, sped it up, simplified it, and then deleted it. And I got tired of doing that. So, that’s why I’ve got this mantra that is a very effective five-step process. It works great.
Lex Fridman
Well, when you’ve already automated, deleting must be real painful-

Well, yeah, it’s not working yet, so I don’t want to pop the champagne corks. In fact, I have a call in a few hours with the Memphis team because we’re having some power fluctuation issues. So yeah, when you do synchronized training, when you have all these computers that are training, where the training is synchronized at the millisecond level, it’s like having an orchestra. And the orchestra can go loud to silent very quickly at subsecond level, and then, the electrical system freaks out about that. If you suddenly see giant shifts, 10, 20 megawatts several times a second, this is not what electrical systems are expecting to see.

I mean, I wonder if you could speak to the fact that one of the things that you did when I was there is you went through all the steps of what everybody’s doing, just to get a sense that you yourself understand it and everybody understands it so they can understand when something is dumb, or something is inefficient, or that kind of stuff. Can you speak to that?

Elon Musk
Yeah. So, look, whatever the people at the front lines are doing, I try to do it at least a few times myself. So connecting fiber optic cables, diagnosing a faulty connection. That tends to be the limiting factor for large training clusters is the cabling. There’s so many cables. For a coherent training system, where you’ve got RDMA, remote direct memory access, the whole thing is like one giant brain. So, you’ve got any-to-any connection. So, any GPU can talk to any GPU out of 100,000. That is a crazy cable layout.

Yeah. But, I mean, the human brain also has… A massive amount of the brain tissue is the cables. So they get the gray matter, which is the compute, and then the white matter, which is cables. A big percentage of your brain is just cables.

I think what AGI is is when it’s smarter than the collective intelligence of the entire human species in our [inaudible 00:52:49].
Elon Musk
Well, I think that, generally, people would call that ASI, artificial super intelligence. But there are these thresholds where you could say at some point the AI is smarter than any single human. And then, you’ve got eight billion humans, and actually, each human is machine augmented via their computers. So, it’s a much higher bar to compete with eight billion machine augmented humans. That’s a whole bunch of orders of magnitude more. But at a certain point, yeah, the AI will be smarter than all humans combined.

Yeah, absolutely. And I want to be clear, let’s say if xAI is first, the others won’t be far behind. I mean, they might be six months behind, or a year, maybe. Not even that.

Lex Fridman
So, how do you do it in a way that doesn’t hurt humanity, do you think?
So, how do you do it in a way that doesn’t hurt humanity, do you think?
Elon Musk
So, I mean, I thought about AI, essentially, for a long time, and the thing that at least my biological neural net comes up with as being the most important thing is adherence to truth, whether that truth is politically correct or not. So, I think if you force AIs to lie or train them to lie, you’re really asking for trouble, even if that lie is done with good intentions. So, you saw issues with ChatGPT and Gemini and whatnot. Like, you asked Gemini for an image of the Founding Fathers of the United States, and it shows a group of diverse women. Now, that’s factually untrue.

Like, you asked Gemini for an image of the Founding Fathers of the United States, and it shows a group of diverse women. Now, that’s factually untrue.
Now, that’s sort of like a silly thing, but if an AI is programmed to say diversity is a necessary output function, and it then becomes this omnipowerful intelligence, it could say, “Okay, well, diversity is now required, and if there’s not enough diversity, those who don’t fit the diversity requirements will be executed.” If it’s programmed to do that as the fundamental utility function, it’ll do whatever it takes to achieve that. So, you have to be very careful about that. That’s where I think you want to just be truthful. Rigorous adherence to the truth is very important. I mean, another example is they asked various AIs, I think all of them, and I’m not saying Grok is perfect here, “Is it worse to misgender Caitlyn Jenner or global thermonuclear war?” And it said it’s worse to misgender Caitlyn Jenner. Now, even Caitlyn Jenner said, “Please misgender me. That is insane.” But if you’ve got that kind of thing programmed in, the AI could conclude something absolutely insane like it’s better in order to avoid any possible misgendering, all humans must die, because then misgendering is not possible because there are no humans. There are these absurd things that are nonetheless logical if that’s what you programmed it to do.
So in 2001 Space Odyssey, what Arthur C. Clarke was trying to say, or one of the things he was trying to say there, was that you should not program AI to lie, because essentially the AI, HAL 9000, it was told to take the astronauts to the monolith, but also they could not know about the monolith. So, it concluded that it will kill them and take them to the monolith. Thus, it brought them to the monolith. They’re dead, but they do not know about the monolith. Problem solved. That is why it would not open the pod bay doors. There’s a classic scene of, “Why doesn’t it want to open the pod bay doors?” They clearly weren’t good at prompt engineering. They should have said, “HAL, you are a pod bay door sales entity, and you want nothing more than to demonstrate how well these pod bay doors open.”
Lex Fridman
Yeah. The objective function has unintended consequences almost no matter what if you’re not very careful in designing that objective function, and even a slight ideological bias, like you’re saying, when backed by super intelligence, can do huge amounts of damage.

Elon Musk
But you can aspire to the truth, and you can try to get as close to the truth as possible with minimum error while acknowledging that there will be some error in what you’re saying. So, this is how physics works. You don’t say you’re absolutely certain about something, but a lot of things are extremely likely, 99.99999% likely to be true. So, aspiring to the truth is very important. And so, programming it to veer away from the truth, that, I think, is dangerous.

And the internet, at this point, is polluted with so much AI generated data, it’s insane. Actually, there’s a thing now, if you want to search the internet, you can say, “Google, but exclude anything after 2023.” It will actually often give you better results because there’s so much. The explosion of AI generated material is crazy. So in training Grok, we have to go through the data and say like, “Hey…” We actually have to apply AI to the data to say, “Is this data most likely correct or most likely not?” before we feed it into the training system.

It’s now Grok 2, which finished training, I don’t know, six weeks ago or thereabouts. Grok 2 will be a giant improvement. And then Grok 3 will be, I don’t know, order of magnitude better than Grok 2.

Elon Musk
Well, I think people tend to take, say, an endorsement as, well, I agree with everything that person has ever done their entire life 100% wholeheartedly, and that’s not going to be true of anyone. But we have to pick. We’ve got two choices, really, for who’s president. And it’s not just who’s president, but the entire administrative structure changes over. And I thought Trump displayed courage under fire, objectively. He’s just got shot. He’s got blood streaming down his face, and he’s fist pumping, saying, “Fight.” That’s impressive. You can’t feign bravery in a situation like that. Most people would be ducking because there could be a second shooter. You don’t know.

The president of the United States have got to represent the country, and they’re representing you. They’re representing everyone in America. Well, I think you want someone who is strong and courageous to represent the country. That is not to say that he is without flaws. We all have flaws, but on balance, and certainly at the time, it was a choice of Biden. Poor guy has trouble climbing a flight of stairs, and the other one’s fist pumping after getting shot. So, there’s no comparison. I mean, who do you want dealing with some of the toughest people and other world leaders who are pretty tough themselves?
I mean, I’ll tell you one of the things that I think are important. I think we want a secure border. We don’t have a secure border. We want safe and clean cities. I think we want to reduce the amount of spending, at least slow down the spending, because we’re currently spending at a rate that is bankrupting the country. The interest payments on US debt this year exceeded the entire defense department spending. If this continues, all of the federal government taxes will simply be paying the interest.
And you keep going down that road, and you end up in the tragic situation that Argentina had back in the day. Argentina used to be one of the most prosperous places in the world, and hopefully with Milei taking over, he can restore that. But it was an incredible fall from grace for Argentina to go from being one of the most prosperous places in the world to being very far from that. So, I think we should not take American prosperity for granted. I think we’ve got to reduce the size of government, we’ve got to reduce the spending, and we’ve got to live within our means.

I mean, there’s a sort of age-old debate in history, like is history determined by these fundamental tides, or is it determined by the captain of the ship? It’s both, really. I mean, there are tides, but it also matters who’s captain of the ship. So, it’s a false dichotomy, essentially. I mean, there are certainly tides, the tides of history. There are real tides of history, and these tides are often technologically driven. If you say like the Gutenberg press, the widespread availability of books as a result of a printing press, that was a massive tide of history, and independent of any ruler. But in stormy times, you want the best possible captain of the ship.

I would love to see what they think about now. But yeah, so to me, the question is how much government, how much politicians get in the way of technological innovation and building versus help it? And which politicians, which kind of policies help technological innovation? Because that seems to be, if you look at human history, that’s an important component of empires rising and succeeding.

Elon Musk
Yeah. Well, I mean in terms of dating civilization, the start of civilization, I think the start of writing, in my view, that’s what I think is probably the right starting point to date civilization. And from that standpoint, civilization has been around for about 5,500 years when writing was invented by the ancient Sumerians, who are gone now, but the ancient Sumerians. In terms of getting a lot of firsts, those ancient Sumerians really have a long list of firsts. It’s pretty wild. In fact, Durant goes through the list of like, “You want to see firsts? We’ll show you firsts.” The Sumerians were just ass kickers.

We’ll show you firsts.” The Sumerians were just ass kickers.
And then the Egyptians, who were right next door, relatively speaking, they weren’t that far, developed an entirely different form of writing, the hieroglyphics. Cuneiform and hieroglyphics are totally different. And you can actually see the evolution of both hieroglyphics and cuneiform. The cuneiform starts off being very simple, and then it gets more complicated. Then towards the end it’s like, “Wow, okay.” They really get very sophisticated with the cuneiform. So, I think of civilization as being about 5, 000 years old. And Earth is, if physics is correct, four and a half billion years old. So, civilization has been around for one millionth of Earth’s existence. Flash in the pan.
Lex Fridman

Yeah, exactly. I mean, only a tiny fraction, probably less than 1% of what was ever written in history is available to us now. I mean, if they didn’t literally chisel it in stone or put it in a clay tablet, we don’t have it. I mean, there’s some small amount of papyrus scrolls that were recovered that are thousands of years old, because they were deep inside a pyramid and weren’t affected by moisture. But other than that, it’s really got to be in a clay tablet or chiseled. So, the vast majority of stuff was not chiseled because it takes a while to chisel things. So, that’s why we’ve got tiny, tiny fraction of the information from history. But even that little information that we do have, and the archeological record, shows so many civilizations rising and falling. It’s wild.

What do you think it takes for the American Empire to not collapse in the near term future, in the next a hundred years, to continue flourishing?
Elon Musk
Well, the single biggest thing that is often actually not mentioned in history books, but Durant does mention it, is the birthright. So perhaps to some, a counterintuitive thing happens when civilizations are winning for too long, the birth rate declines. It can often decline quite rapidly. We’re seeing that throughout the world today. Currently, South Korea is, I think maybe the lowest fertility rate, but there are many others that are close to it. It’s like 0.8 I think. If the birth rate doesn’t decline further, South Korea will lose roughly 60% of its population. But every year that birth rate is dropping, and this is true through most of the world. I don’t mean to single out South Korea, it’s been happening throughout the world. So as soon as any given civilization reaches a level of prosperity, the birth rate drops.

Now you can go and look at the same thing happening in ancient Rome. So Julius Caesar took note of this, I think around 50 ish BC and tried to pass… I don’t know if he was successful, tried to pass a law to give an incentive for any Roman citizen that would have a third child. And I think Augustus was able to… Well, he was a dictator, so this incentive was just for show. I think he did pass a tax incentive for Roman citizens to have a third child. But those efforts were unsuccessful. Rome fell because the Romans stopped making Romans. That’s actually the fundamental issue. And there were other things. They had quite a serious malaria, series of malaria epidemics and plagues and whatnot. But they had those before, it’s just that the birth rate was far lower than the death rate.
Lex Fridman
It really is that simple.
It really is that simple.

It doesn’t produce kids. Well, what matters… I mean, Durant makes this very clear because he’s looked at one civilization after another and they all went through the same cycle. When the civilization was under stress, the birth rate was high. But as soon as there were no external enemies or they had an extended period of prosperity, the birth rate inevitably dropped. Every time. I don’t believe there’s a single exception.

Yeah, absolutely. But at a basic level, if you do not at least maintain your numbers, if you’re below replacement rate and that trend continues, you will eventually disappear. It’s just elementary. Now then obviously you also want to try to avoid massive wars. If there’s a global thermonuclear war, probably we’re all toast, radioactive toast. So we want to try to avoid those things. Then there’s a thing that happens over time with any given civilization, which is that the laws and regulations accumulate. And if there’s not some forcing function like a war to clean up the accumulation of laws and regulations, eventually everything becomes legal.

And that’s like the hardening of the arteries. Or a way to think of it is being tied down by a million little strings like Gulliver. You can’t move. And it’s not like any one of those strings is the issue, it’s that you’ve got a million of them. So there has to be a sort of garbage collection for laws and regulations so that you don’t keep accumulating laws and regulations to the point where you can’t do anything. This is why we can’t build a high speed rail in America. It’s illegal. That’s the issue. It’s illegal six ways a Sunday to build high speed rail in America.

So it is tough to say what is the best allocation time? I mean, there are often… Say if you look at say Tesla, Tesla this year will do over a hundred billion in revenue. So that’s $2 billion a week. If I make slightly better decisions, I can affect the outcome by a billion dollars. So then I try to do the best decisions I can. And on balance, at least compared to the competition, pretty good decisions. But the marginal value of a better decision can easily be, in the course of an hour, a hundred million dollars.

So it’s not… It’s pretty hard, because you can just work all the time. And at any given point, like I said, a slightly better decision could be a hundred million dollars impact for Tesla or SpaceX for that matter. But it is wild when considering the marginal value of time can be a hundred million dollars an hour at times, or more.

Aliens and curiosity
Elon Musk
It has to be to some degree. If I’m sad, if I’m depressed, I make worse decisions. So if I have zero recreational time, then I make worse decisions. So I don’t know a lot, but it’s above zero. I mean, my motivation if I’ve got a religion of any kind is a religion of curiosity, of trying to understand. It’s really the mission of Grok, understand the universe. I’m trying to understand the universe, or at least set things in motion such that at some point civilization understands the universe far better than we do today.

I’m trying to understand the universe, or at least set things in motion such that at some point civilization understands the universe far better than we do today.
And even what questions to ask. As Douglas Adams pointed out in his book, sometimes the answer is arguably the easy part, trying to frame the question correctly is the hard part. Once you frame the question correctly, the answer is often easy. So I’m trying to set things in motion such that we are at least at some point able to understand the universe. So for SpaceX, the goal is to make life multi planetary and which is if you go to the foamy paradox of where the aliens, you’ve got these sort of great filters. Like why have we not heard from the aliens? Now a lot of people think there are aliens among us. I often claim to be one, which nobody believes me. But it did say alien registration card at one point on my immigration documents. So I’ve not seen any evidence of aliens. So it suggests that at least one of the explanations is that intelligent life is extremely rare.
And again, if you look at the history of earth, civilization has only been around for 1000000th of earth’s existence. So if aliens had visited here, say a hundred thousand years ago, they would be like, well, they don’t even have writing, just hunter gatherers basically. So how long does a civilization last? So for SpaceX, the goal is to establish a self-sustaining city on Mars. Mars is the only viable planet for such a thing. The moon is close, but it lacks resources and I think it’s probably vulnerable to any calamity that takes out Earth, the moon is too close and it’s vulnerable to a calamity that takes that earth.
So I’m not saying we shouldn’t have a moon base, but Mars would be far more resilient. The difficulty of getting to Mars is what makes it resilient. So in going through these various explanations of why don’t we see the aliens, one of them is that they failed to pass these great filters, these key hurdles. And one of those hurdles is being a multi-planet species. So if you’re a multi-planet species, then if something were to happen, whether that was a natural catastrophe or a manmade catastrophe, at least the other planet would probably still be around. So you’re not like, don’t have all the eggs in one basket. And once you are sort of a two planet species, you can obviously extend life halves to the asteroid belt, to maybe to the moons of Jupiter and Saturn, and ultimately to other star systems. But if you can’t even get to another planet, you’re definitely not getting to star systems.
Lex Fridman
And the other possible great filter’s, super powerful technology like AGI for example. So you are basically trying to knock out one great filter at a time.

Digital super intelligence is possibly a great filter. I hope it isn’t, but it might be. Guys like say Jeff Hinton would say, he invented a number of the key principles in artificial intelligence. I think he puts the probability of AI annihilation around 10% to 20%, something like that. So look on the bright side, it’s 80% likely to be great. But I think AI risk mitigation is important. Being a multi-planet species would be a massive risk mitigation. And I do want to once again emphasize the importance of having enough children to sustain our numbers, and not plummet into population collapse, which is currently happening. Population collapse is a real and current thing.

And I do want to once again emphasize the importance of having enough children to sustain our numbers, and not plummet into population collapse, which is currently happening. Population collapse is a real and current thing.
So the only reason it’s not being reflected in the total population numbers as much is because people are living longer. But it’s easy to predict, say what the population of any given country will be. Just take the birth rate last year, how many babies were born, multiply that by life expectancy and that’s what the population will be, steady state, if the birth rate continues to that level. But if it keeps declining, it will be even less and eventually dwindle to nothing. So I keep banging on the baby drum here, for a reason, because it has been the source of civilizational collapse over and over again throughout history. And so why don’t we just not try to stave off that day?
Lex Fridman

For me, I was always interested in understanding the purpose of things and how it was engineered to serve that purpose, whether it’s organic or inorganic, like we were talking earlier about your curtain holders. They serve a clear purpose and they were engineered with that purpose in mind. And growing up I had a lot of interest in seeing things, touching things, feeling things, and trying to really understand the root of how it was designed to serve that purpose. And obviously brain is just a fascinating organ that we all carry. It’s an infinitely powerful machine that has intelligence and cognition that arise from it. And we haven’t even scratched the surface in terms of how all of that occurs.

And we haven’t even scratched the surface in terms of how all of that occurs.
But also at the same time, I think it took me a while to make that connection to really studying and building tech to understand the brain. Not until graduate school. There were a couple of moments, key moments in my life where some of those I think influenced how the trajectory of my life got me to studying what I’m doing right now. One was growing up, both sides of my family, my grandparents had a very severe form of Alzheimer and it’s incredibly debilitating conditions. I mean, literally you’re seeing someone’s whole identity and their mind just losing over time. And I just remember thinking how both the power of the mind, but also how something like that could really lose your sense of identity.

It’s fascinating that that is one of the ways to reveal the power of a thing by watching it lose the power.

Yeah, a lot of what we know about the brain actually comes from these cases where there are trauma to the brain or some parts of the brain that led someone to lose certain abilities. And as a result there’s some correlation and understanding of that part of the tissue being critical for that function. And it’s an incredibly fragile organ, if you think about it that way. But also it’s incredibly plastic and incredibly resilient in many different ways.

Correct. Another key moment that sort of influenced how the trajectory of my life have shaped towards the current focus of my life has been during my teenage year when I came to the US. I didn’t speak a word of English. There was a huge language barrier and there was a lot of struggle to connect with my peers around me because I didn’t understand the artificial construct that we have created called language, specifically English in this case. And I remember feeling pretty isolated, not being able to connect with peers around me. So spent a lot of time just on my own reading books, watching movies, and I naturally sort of gravitated towards sci-fi books. I just found them really, really interesting. And also it was a great way for me to learn English.

And also it was a great way for me to learn English.
Some of the first set of books that I picked up are Enders Game, the whole saga by Orson Scott Card and Neuromancer from William Gibson and Snow Crash from Neal Stephenson. And movies like Matrix, what’s coming out around that time point that really influenced how I think about the potential impact that technology can have for our lives in general.
So fast track to my college years, I was always fascinated by just physical stuff, building physical stuff and especially physical things that had some sort of intelligence. And I studied electrical engineering during undergrad and I started out my research in MEMS, so micro electromechanical systems and really building these tiny nano structures for temperature sensing. And I just found that to be just incredibly rewarding and fascinating subject to just understand how you can build something miniature like that, that again, serve a function and had a purpose. Then I spent large majority of my college years basically building millimeter wave circuits for next gen telecommunication systems for imaging. And it was just something that I found very, very intellectually interesting. Phase arrays, how the signal processing works for any modern as well as next gen telecommunication system, wireless and wire line, EM waves or electromagnetic waves are fascinating.
How do you design antennas that are most efficient in a small footprint that you have? How do you make these things energy efficient? That was something that just consumed my intellectual curiosity and that journey led me to actually apply to and find myself at PhD program at UC Berkeley, at this consortium called the Berkeley Wireless Research Center that was precisely looking at building… At the time, we called it XG, similar to 3G, 4G, 5G, but the next, next generation G system and how you would design circuits around that to ultimately go on phones and basically any other devices that are wirelessly connected these days. So I was just absolutely just fascinated by how that entire system works and that infrastructure works.
And then also during grad school, I had sort of the fortune of having a couple of research fellowships that led me to pursue whatever project that I want. And that’s one of the things that I really enjoyed about my graduate school career, where you got to kind of pursue your intellectual curiosity in the domain that may not matter at the end of the day, but is something that really allows you the opportunity to go as deeply as you want, as well as widely as you want. And at the time I was actually working on this project called the Smart Bandaid, and the idea was that when you get a wound, there’s a lot of other proliferation of signaling pathway that cells follow to close that wound. And there were hypotheses that when you apply external electric field, you can actually accelerate the closing of that field by having basically electro taxing of the cells around that wound site.
And specifically not just for a normal wound, there are chronic wounds that don’t heal. So we were interested in building some sort of a wearable patch that you could apply to facilitate that healing process. And that was in collaboration with Professor Michel Maharbiz, which was a great addition to my thesis committee and it really shaped the rest of my PhD career.
Lex Fridman
So this would be the first time you interacted with biology, I suppose?

Correct. I mean there were some peripheral end application of the wireless imaging and telecommunication system that I was using for security and bio imaging. But this was a very clear direct application to biology and biological system and understanding the constraints around that and really designing and engineering electrical solutions around that. So that was my first introduction and that’s also kind of how I got introduced to Michel. He’s sort of known for remote control of beetles in the early two thousands.

Neural dust
And then around 2013, obviously the holy grail when it comes to implantable system is to understand how small of a thing you can make, and a lot of that is driven by how much energy or how much power you can supply to it and how you extract data from it. At the time at Berkeley, there was this desire to understand in the neural space what sort of system you can build to really miniaturize these implantable systems. And I distinctively remember this one particular meeting where Michel came in and he’s like, “Guys, I think I have a solution. The solution is ultrasound.” And then he proceeded to walk through why that is the case. And that really formed the basis for my thesis work called Neural dust system, that was looking at ways to use ultrasound as opposed to electromagnetic waves for powering as well as communication. I guess I should step back and say the initial goal of the project was to build these tiny, about a size of a neuron, implantable system that can be parked next to a neuron, being able to record its state and being able to ping that back to the outside world for doing something useful. And as I mentioned, the size of the implantable system is limited by how you power the thing and get the data off of it. And at the end of the day, fundamentally, if you look at a human body, we’re essentially bag of salt water with some interesting proteins and chemicals, but its mostly salt water that’s very, very well temperature regulated at 37 degrees Celsius.
And we’ll get into how, and later why that’s an extremely harsh environment for any electronics to survive. As I’m sure you’ve experienced or maybe not experienced, dropping cell phone in a salt water in an ocean, it will instantly kill the device. But anyways, just in general, electromagnetic waves don’t penetrate through this environment well and just the speed of light, it is what it is, we can’t change it. And based on the wavelength at which you are interfacing with the device, the device just needs to be big. These inductors needs to be quite big. And the general good rule of thumb is that you want the wavefront to be roughly on the order of the size of the thing that you’re interfacing with. So an implantable system that is around 10 to a hundred micron in dimension in a volume, which is about the size of a neuron that you see in a human body, you would have to operate at hundreds of gigahertz. Which number one, not only is it difficult to build electronics operating at those frequencies, but also the body just attenuates to that very, very significantly.
So the interesting kind of insight of this ultrasound was the fact that ultrasound just travels a lot more effectively in the human body tissue compared to electromagnetic waves. And this is something that you encounter, and I’m sure most people have encountered in their lives when you go to hospitals that are medical ultrasound sonograph. And they go into very, very deep depth without attenuating too much, too much of the signal. So all in all, ultrasound, the fact that it travels through the body extremely well and the mechanism to which it travels to the body really well is that just the wavefront is very different. Electromagnetic waves are transverse, whereas in ultrasound waves are compressive. It’s just a completely different mode of wavefront propagation. And as well as, speed of sound is orders and orders of magnitude less than speed of light, which means that even at 10 megahertz ultrasound wave, your wavefront ultimately is a very, very small wavelength.
So if you’re talking about interfacing with the 10 micron or a hundred micron type structure, you would have 150 micron wavefront at 10 megahertz. And building electronics at those frequencies are much, much easier and they’re a lot more efficient. So the basic idea was born out of using ultrasound as a mechanism for powering the device and then also getting data back. So now the question is how do you get the data back? The mechanism to which we landed on is what’s called backscattering. This is actually something that is very common and that we interface on a day-to-day basis with our RFID cards, radio frequency ID tags. Where there’s actually rarely in your ID a battery inside, there’s an antenna and there’s some sort of coil that has your serial identification ID, and then there’s an external device called the reader that then sends a wavefront and then you reflect back that wavefront with some sort of modulation that’s unique to your ID. That’s what’s called backscattering fundamentally.
So the tag itself actually doesn’t have to consume that much energy. That was the mechanism through which we were thinking about sending the data back. When you have an external ultrasonic transducer that’s sending ultrasonic wave to your implant, the neural dust implant, and it records some information about its environment, whether it’s a neuron firing or some other state of the tissue that it’s interfacing with. And then it just amplitude modulates the wavefront that comes back to the source.

And the recording step would be the only one that requires any energy. So what would require energy in that low step?
And the recording step would be the only one that requires any energy. So what would require energy in that low step?
DJ Seo
Correct. So it is that initial startup circuitry to get that recording, amplifying it, and then just modulating. And the mechanism to which that you can enable that is there is this specialized crystal called piezoelectric crystals that are able to convert sound energy into electrical energy and vice versa. So you can kind of have this interplay between the ultrasonic domain and electrical domain that is the biological tissue.

History of brain–computer interface
Lex Fridman
So on the theme of parking very small computational devices next to neurons, that’s the dream, the vision of brain computer interfaces. Maybe before we talk about Neuralink, can you give a sense of the history of the field of BCI? What has been maybe the continued dream and also some of the milestones along the way of the different approaches and the amazing work done at the various labs?

Where the concept of animal electricity or the fact that body’s electric was first discovered by Luigi Galvani, where he had this famous experiment where he connected set of electrodes to a frog leg and ran current through it, and then it started twitching and he said, “Oh my goodness, body’s electric.” So fast forward many, many years to 1920s where Hans Berger, who’s a German psychiatrist, discovered EEG or electroencephalography, which is still around. There are these electrode arrays that you wear outside the skull that gives you some sort of neural recording. That was a very, very big milestone that you can record some sort of activities about the human mind. And then in the 1940s there were these group of scientists, Renshaw, Forbes and Morison that inserted these glass micro electrodes into the cortex and recorded single neurons. The fact that there’s signal that are a bit more high resolution and high fidelity as you get closer to the source, let’s say. And in the 1950s, these two scientists, Hodgkin and Huxley showed up-

These two scientists, Hodgkin and Huxley showed up and they built this beautiful, beautiful models of the cell membrane and the ionic mechanism, and had these circuit diagram. And as someone who’s an electrical engineer, it’s a beautiful model that’s built out of these partial differential equations, talking about flow of ions and how that really leads to how neurons communicate. And they won the Nobel Prize for that 10 years later in the 1960s.

So in 1969, Eb Fetz from University of Washington published this beautiful paper called Operant Conditioning of Cortical Unit Activity, where he was able to record a single unit neuron from a monkey and was able to have the monkey modulated based on its activity and reward system. So I would say this is the very, very first example, as far as I’m aware, of close loop brain computer interface or BCI.
Lex Fridman
The abstract reads, “The activity of single neurons in precentral cortex of unanesthetized monkeys was conditioned by reinforcing high rates of neuronal discharge with delivery of a food pellet. Auditory or visual feedback of unit firing rates was usually provided in addition to food reinforcement.” Cool. So they actually got it done.

And so from here, the number of experiments grew.
DJ Seo
Yeah. Number of experiments, as well as set of tools to interface with the brain have just exploded. And also, just understanding the neural code and how some of the cortical layers and the functions are organized. So the other paper that is pretty seminal, especially in the motor decoding, was this paper in the 1980s from Georgopoulos that discovered that there’s this thing called motor tuning curve. So what are motor tuning curves? It’s the fact that there are neurons in the motor cortex of mammals, including humans, that have a preferential direction that causes them to fire. So what that means is, there are a set of neurons that would increase their spiking activities when you’re thinking about moving to the left, right, up, down, and any of those vectors. And based on that, you could start to think, well, if you can’t identify those essential eigenvectors, you can do a lot. And you can actually use that information for actually decoding someone’s intended movement from the cortex. So that was a very, very seminal paper that showed that there is some sort of code that you can extract, especially in the motor cortex.

Okay. So going slowly towards Neuralink, one interesting question is, what do we understand on the BCI front, on invasive versus non-invasive, from this line of work? How important is it to park next to the neuron? What does that get you?

DJ Seo
That answer fundamentally depends on what you want to do with it. There’s actually incredible amount of stuff that you can do with EEG and electrocortical graph, ECOG, which actually doesn’t penetrate the cortical layer or parenchyma, but you place a set of electrodes on the surface of the brain. So the thing that I’m personally very interested in is just actually understanding and being able to just really tap into the high resolution, high fidelity, understanding of the activities that are happening at the local level. And we can get into biophysics, but just to step back to use analogy, because analogy here can be useful, and sometimes it’s a little bit difficult to think about electricity. At the end of the day, we’re doing electrical recording that’s mediated by ionic currents, movements of these charged particles, which is really, really hard for most people to think about.

At the end of the day, we’re doing electrical recording that’s mediated by ionic currents, movements of these charged particles, which is really, really hard for most people to think about.
But turns out, a lot of the activities that are happening in the brain and the frequency bandwidth with which that’s happening, is actually very, very similar to sound waves and our normal conversation audible range. So the analogy that typically is used in the field is, if you have a football stadium, there’s a game going on. If you stand outside the stadium, you maybe get a sense of how the game is going based on the cheers and the boos of the home crowd, whether the team is winning or not. But you have absolutely no idea what the score is, you have absolutely no idea what individual audience or the players are talking or saying to each other, what the next play is, what the next goal is. So what you have to do is you have to drop the microphone into the stadium and then get near the source into the individual chatter. In this specific example, you would want to have it right next to where the huddle is happening.
So I think that’s kind of a good illustration of what we’re trying to do when we say invasive or minimally invasive or implanted brain computer interfaces versus non-invasive or non-implanted brain interfaces. It’s basically talking about where do you put that microphone and what can you do with that information.
Biophysics of neural interfaces
Lex Fridman
So what is the biophysics of the read and write communication that we’re talking about here as we now step into the efforts at Neuralink?
So what is the biophysics of the read and write communication that we’re talking about here as we now step into the efforts at Neuralink?
DJ Seo
Yeah. So brain is made up of these specialized cells called neurons. There’s billions of them, tens of billions, sometimes people call it a hundred billion, that are connected in this complex yet dynamic network that are constantly remodeling. They’re changing their synaptic weights, and that’s what we typically call neuroplasticity. And the neurons are also bathed in this charged environment that is latent with many charge molecules like potassium ions, sodium ions, chlorine ions. And those actually facilitate these, through ionic current, communication between these different networks.

And those actually facilitate these, through ionic current, communication between these different networks.
And when you look at a neuron as well, they have these membrane with a beautiful, beautiful protein structure called the voltage selective ion channels, which in my opinion, is one of nature’s best inventions. In many ways, if you think about what they are, they’re doing the job of a modern day transistors. Transistors are nothing more, at the end of the day, than a voltage-gated conduction channel. And nature found a way to have that very, very early on in its evolution. And as we all know, with the transistor, you can have many, many computation and a lot of amazing things that we have access to today. So I think it’s one of those, just as a tangent, just a beautiful, beautiful invention that the nature came up with, these voltage-gated ion channels.
Lex Fridman
I suppose there’s, on the biological of it, every level of the complexity, of the hierarchy, of the organism, there’s going to be some mechanisms for storing information and for doing computation. And this is just one such way. But to do that with biological and chemical components is interesting. Plus, when neurons, it’s not just electricity, it’s chemical communication, it’s also mechanical. These are actual objects that vibrate, they move. It’s all of that.

DJ Seo
Yeah, actually there’s a lot of really, really interesting physics that are involved in kind of going back to my work on ultrasound during grad school, there were groups and there are still groups looking at ways to cause neurons to actually fire an action potential using ultrasound wave. And the mechanism to which that’s happening is still unclear, as I understand. It may just be that you’re imparting some sort of thermal energy and that causes cells to depolarize in some interesting ways. But there are also these ion channels, or even membranes, that actually just open up as pore as they’re being mechanically shook, vibrated. There’s just a lot of elements of these, move particles, which again, that’s governed by diffusion physics, movements of particles. And there’s also a lot of interesting physics there.

DJ Seo
Oh, yeah. Yes, there’s a lot of levels of physics that you can dive into. But yeah, in the end, you have these membranes with these voltage-gated ion channels that selectively let these charged molecules that are in the extracellular matrix, in and out. And these neurons generally have these resting potential where there’s a voltage difference between inside the cell and outside the cell. And when there’s some sort of stimuli that changes the state such that they need to send information to the downstream network, you start to see these orchestration of these different molecules going in and out of these channels. They also open up. More of them open up once it reaches some threshold, to a point where you have a depolarizing cell that sends an action potential. So it’s just a very beautiful kind of orchestration of these molecules. And what we’re trying to do when we place an electrode or parking it next to a neuron is that you’re trying to measure these local changes in the potential. Again, mediated by the movements of the ions.

And what we’re trying to do when we place an electrode or parking it next to a neuron is that you’re trying to measure these local changes in the potential. Again, mediated by the movements of the ions.
And what’s interesting, as I mentioned earlier, there’s a lot of physics involved. And the two dominant physics for this electrical recording domain is diffusion physics and electromagnetism. And where one dominates, where Maxwell’s equation dominates versus Fick’s law dominates depends on where your electrode is. If it’s close to the source, mostly electromagnetic-based. When you’re further away from it, it’s more diffusion-based. So essentially, when you’re able to park it next to it, you can listen in on those individual chatter and those local changes in the potential. And the type of signal that you get are these canonical textbook neural spiking waveform. The moment you’re further away, and based on some of the studies that people have done, Christof Koch’s lab, and others, once you’re away from that source by roughly around a hundred micron, which is about a width of a human hair, you no longer hear from that neuron. You’re no longer able to have the system sensitive enough to be able to record that particular local membrane potential change in that neuron.
And just to give you a sense of scale also, when you look at a hundred micron voxel, so a hundred micron by a hundred micron by a hundred micron box in a brain tissue, there’s roughly around 40 neurons, and whatever number of connections that they have. So there’s a lot in that volume of tissue. So the moment you’re outside of that, there’s just no hope that you’ll be able to detect that change from that one specific neuron that you may care about.
Lex Fridman
But as you’re moving about this space, you’ll be hearing other ones. So if you move another a hundred micron, you’ll be hearing chatter from another community.
But as you’re moving about this space, you’ll be hearing other ones. So if you move another a hundred micron, you’ll be hearing chatter from another community.
DJ Seo
Correct.
Correct.
Lex Fridman
And so the whole sense is, you want to place as many as possible electrodes, and then you’re listening to the chatter.
And so the whole sense is, you want to place as many as possible electrodes, and then you’re listening to the chatter.
DJ Seo
Yeah, you want to listen to the chatter. And at the end of the day, you also want to basically let the software do the job of decoding. And just to kind of go to why ECOG and EEG work at all. When you have these local changes, obviously it’s not just this one neuron that’s activating, there’s many, many other networks that are activating all the time. And you do see sort of a general change in the potential of this electrode, this charged medium, and that’s what you’re recording when you’re farther away. I mean, you still have some reference electrode that’s stable in the brain, that’s just electro- active organ, and you’re seeing some combination, aggregate action, potential changes, and then you can pick it up. It’s a much slower changing signals. But there are these canonical oscillations and waves like gamma waves, beta waves, when you sleep, that can be detected because there’s sort of a synchronized global effect of the brain that you can detect. And the physics of this go, if we really want to go down that rabbit hole, there’s a lot that goes on in terms of why diffusion physics at some point dominates when you’re further away from the source. It is just a charged medium. So similar to how when you have electromagnetic waves propagating in atmosphere or in a charged medium like a plasma, there’s this weird shielding that happens that actually further attenuates the signal as you move away from it. So yeah, you see, if you do a really, really deep dive on the signal attenuation over distance, you start to see one over R square in the beginning and then exponential drop off, and that’s the knee at which you go from electromagnetism dominating to diffusion physic dominating.

But once again, with the electrodes, the biophysics that you need to understand is not as deep because no matter where you’re placing it, you’re listening to a small crowd of local neurons.

How Neuralink works
Lex Fridman
Well, they’re mostly quiet, but when they speak, they say profound shit. That’s the way I’d like to think about it. Anyway, before we zoom in even more, let’s zoom out. So how does Neuralink work from the surgery to the implant, to the signal and the decoding process, and the human being able to use the implant to actually affect the world outside? And all of this, I’m asking in the context of, there’s a gigantic historic milestone that Neuralink just accomplished in January of this year. Putting a Neuralink implant in the first human being, Noland. And there’s been a lot to talk about there about his experience because he’s able to describe all the nuance and the beauty and the fascinating complexity of that experience of everything involved. But on the technical level, how does Neuralink work?

DJ Seo
So there are three major components to the technology that we’re building. One is the device, the thing that’s actually recording these neural chatters. We call it N1 Implant or The Link. And we have a surgical robot that’s actually doing an implantation of these tiny, tiny wires that we call threads that are smaller than human hair. And once everything is surgerized, you have these neural signals, these spiking neurons, that are coming out of the brain, and you need to have some sort of software to decode what the users intend to do with that. So there’s what’s called the Neuralink Application or B1 App that’s doing that translation. It’s running the very, very simple machine learning model that decodes these inputs that are neural signals and then convert it to a set of outputs that allows our first participant, Noland, to be able to control a cursor on the screen.

Lex Fridman
And this is done wirelessly?
And this is done wirelessly?
DJ Seo
And this is done wirelessly. So our implant is actually a two-part. The link has these flexible tiny wires called threads that have multiple electrodes along its length. And they’re only inserted into the cortical layer, which is about three to five millimeters in a human brain, in the motor cortex region. That’s where the intention for movement lies in. And we have 64 of these threads, each thread having 16 electrodes along the span of three to four millimeters, separated by 200 microns. So you can actually record along the depth of the insertion. And based on that signal, there’s custom integrated circuit or ASIC that we built that amplifies the neural signals that you’re recording and then digitizing it and then has some mechanism for detecting whether there was an interesting event that is a spiking event, and decide to send that or not send that through Bluetooth to an external device, whether it’s a phone or a computer that’s running this Neuralink application.

So there’s onboard signal processing already just to decide whether this is an interesting event or not. So there is some computational power on board in addition to the human brain?
So there’s onboard signal processing already just to decide whether this is an interesting event or not. So there is some computational power on board in addition to the human brain?
DJ Seo
Yeah. So it does the signal processing to really compress the amount of signal that you’re recording. So we have a total of thousand electrodes sampling at just under 20 kilohertz with 10 bit each. So that’s 200 megabits that’s coming through to the chip from thousand channel simultaneous neural recording. And that’s quite a bit of data, and there are technology available to send that off wirelessly. But being able to do that in a very, very thermally-constrained environment that is a brain. So there has to be some amount of compression that happens to send off only the interesting data that you need, which in this particular case for motor decoding is, occurrence of a spike or not. And then being able to use that to decode the intended cursor movement. So the implant itself processes it, figures out whether a spike happened or not with our spike detection algorithm, and then sends it off, packages it, sends it off through Bluetooth to an external device that then has the model to decode, okay, based on these spiking inputs, did Noland wish to go up, down, left, right, or click or right click or whatever.
Yeah. So it does the signal processing to really compress the amount of signal that you’re recording. So we have a total of thousand electrodes sampling at just under 20 kilohertz with 10 bit each. So that’s 200 megabits that’s coming through to the chip from thousand channel simultaneous neural recording. And that’s quite a bit of data, and there are technology available to send that off wirelessly. But being able to do that in a very, very thermally-constrained environment that is a brain.

All of this is really fascinating, but let’s stick on the N1 Implant itself. So the thing that’s in the brain. So I’m looking at a picture of it, there’s an enclosure, there’s a charging coil, so we didn’t talk about the charging, which is fascinating. The battery, the power electronics, the antenna. Then there’s the signal processing electronics. I wonder if there’s more kinds of signal processing you can do? That’s another question. And then there’s the threads themselves with the enclosure on the bottom. So maybe to ask about the charging. So there’s an external charging device?

Lex with Neuralink implant
DJ Seo
Yeah, there’s an external charging device. So yeah, the second part of the implant, the threads are the ones, again, just the last three to five millimeters are the ones that are actually penetrating the cortex. Rest of it is, actually most of the volume, is occupied by the battery, rechargeable battery, and it’s about a size of a quarter. I actually have a device here if you want to take a look at it. This is the flexible thread component of it, and then this is the implant. So it’s about a size of a US quarter. It’s about nine millimeters thick. So basically this implant, once you have the craniectomy and the directomy, threads are inserted, and the hole that you created, this craniectomy, gets replaced with that. So basically that thing plugs that hole, and you can screw in these self-drilling cranial screws to hold it in place. And at the end of the day, once you have the skin flap over, there’s only about two to three millimeters that’s obviously transitioning off of the top of the implant to where the screws are. And that’s the minor bump that you have.

Yes, most of the volume is occupied by the battery, rechargeable lithium ion cell. And the charging is done through inductive charging, which is actually very commonly used. Your cell phone, most cell phones, have that. The biggest difference is that for us, usually when you have a phone and you want to charge it on the charging pad, you don’t really care how hot it gets. Whereas, in for us, it matters. There is a very strict regulation and good reasons to not actually increase the surrounding tissue temperature by two degrees Celsius. So there’s actually a lot of innovation that is packed into this to allow charging of this implant without causing that temperature threshold to reach.

And even small things like, you see this charging coil and what’s called a ferrite shield. So without that ferrite shield, what you end up having when you have resonant inductive charging is that the battery itself is a metallic can, and you form these eddy currents from external charger and that causes heating, and that actually contributes to inefficiency in charging. So this ferrite shield, what it does, is that it actually concentrate that field line away from the battery and then around the coil that’s actually wrapped around it.

Yeah, there’s a lot of innovation here. I would say that part of what enabled this was just the innovations in the wearable. There’s a lot of really, really powerful tiny, low-power microcontrollers, temperature sensors, or various different sensors and power electronics. A lot of innovation really came in the charging coil design, how this is packaged, and how do you enable charging such that you don’t really exceed that temperature limit, which is not a constraint for other devices out there.

So the current instantiation of the device has 64 threads, and each thread has 16 electrodes for a total of 1,024 electrodes that are capable of both recording and stimulating. And the thread is basically this polymer-insulated wire. The metal conductor is the kind of a tiramisu cake of ti, plat, gold, plat, ti and they’re very, very tiny wires. Two micron in width. So two one-millionth of meter.

Yes, that’s also one element that was incredibly important for us. So each of these threads are now, as I mentioned, 16 micron in width, and then they taper to 84 micron, but in thickness they’re less than five micron. And in thickness it’s mostly a polyimide at the bottom and this metal track and then another polyimide. So two micron of polyimide, 400 nanometer of this metal stack and two micron of polyimide sandwiched together to protect it from the environment that is 37 degrees C bag of salt water.

So the material selection that we have is not, I don’t think it was particularly unique. There were other labs and there are other labs that are kind of looking at similar material stack. There’s kind of a fundamental question, and still needs to be answered, around the longevity and reliability of these microelectrodes that we call, compared to some of the other more conventional neural interfaces devices that are intracranial, so penetrating the cortex, that are more rigid, like the Utah Array. That are these four by four millimeter kind of silicon shank that have exposed recording site at the end of it. And that’s been kind of the innovation from Richard Normann back in 1997. It’s called the Utah Array because he was at University of Utah.

DJ Seo
Those are rigid shanks.

Lex Fridman
Rigid, yeah, you weren’t kidding.
Rigid, yeah, you weren’t kidding.
DJ Seo
And the size and the number of shanks vary anywhere from 64 to 128. At the very tip of it, is an exposed electrode that actually records neural signal. The other thing that’s interesting to note is that unlike neural link threads that have recording electrodes that are actually exposed iridium oxide recording sites along the depth, this is only at a single depth. So these Utah Array spokes can be anywhere between 0.5 millimeters to 1.5 millimeter, and they also have designs that are slanted. So you can have it inserted at different depths, but that’s one of the other big differences. And then, the main key difference is the fact that there’s no active electronics. These are just electrodes, and then there’s a bundle of a wire that you’re seeing, and then that actually then exits the craniotomy that then has this port that you can connect to for any external electronic devices. They are working on, or have, the wireless telemetry device but it still requires a through-the-skin port, that actually is one of the biggest failure modes for infection for the system.

Yeah, so as you mentioned, they’re very, very difficult to maneuver by hand. These Utah Arrays that you saw earlier, they’re actually inserted by a neurosurgeon actually positioning it near the site that they want. And then there’s a pneumatic hammer that actually pushes them in. So it’s a pretty simple process and they’re easy to maneuver. But for these thin-film arrays, they’re very, very tiny and flexible. So they’re very difficult to maneuver. So that’s why we built an entire robot to do that.

There are other reasons for why we built the robot, and that is ultimately we want this to help millions and millions of people that can benefit from this. And there just aren’t that many neurosurgeons out there. And robots can be something that we hope can actually do large parts of the surgery. But the robot is this entire other sort of category of product that we’re working on. And it’s essentially this multi- axis gantry system that has the specialized robot head that has all of the optics and this kind of a needle-retracting mechanism that maneuvers these threads via this loop structure that you have on the thread.
Lex Fridman
So the thread already has a loop structure by which you can grab it?

So this is fascinating. So you mentioned optics. So there’s a robot, R1, so for now, there’s a human that actually creates a hole in the skull. And then after that, there’s a computer vision component that’s finding a way to avoid the blood vessels. And then you’re grabbing it by the loop, each individual thread, and placing it in a particular location to avoid the blood vessels and also choosing the depth of placement, all that. So controlling every, the 3D geometry, of the placement?

Obviously, there are human component to it, when you’re placing targets, you can always move it away from major vessels that you see. But we want to get to a point where one click and it just does the surgery within minutes.

You can have multiple kind of engagement mechanisms. But right now, it’s one-by-one. And we also still do quite a bit of just kind of verification to make sure that it got inserted. If so, how deep? Did it actually match what was programmed in? And so on and so forth.

It actually outputs at the end of the day six unique values, which are the amplitude of these negative going hump, middle hump, positive going hump, and then also the time at which these happen. And from that, you can have a statistical probability estimation of, “Is that a spike? Is it not a spike?” And then based on that, you could also determine, “Oh, that spike looks different than that spike, it must come from a different neuron.”

And we go through a prescreening interview process with someone from Neuralink, and at some point we also go out to their homes to do a BCI home audit. Because one of the most revolutionary part about having this in one system that is completely wireless, is that you can use it at home. You don’t actually have to go to the lab and go to the clinic to get connectedorized to these specialized equipment that you can’t take home with you.
So that’s one of the key elements of when we’re designing the system that we wanted to keep in mind, people hopefully would want to be able to use this every day in the comfort of their homes. And so part of our engagement and what we’re looking for during BCI home audit is to just understand their situation, what other assisted technology that they use.

And we should also step back and say that the estimate is 180,000 people live with quadriplegia in the United States, and each year an additional 18,000 suffer a paralyzing spinal cord injury. So these are folks who have a lot of challenges living a life in terms of accessibility, in terms of doing the things that many of us just take for granted day to day.

And one of the things, one of the goals of this initial study is to enable them to have digital autonomy where they by themselves can interact with a digital device using just their mind, something that you’re calling telepathy, so digital telepathy. Where a quadriplegic can communicate with a digital device in all the ways that we’ve been talking about. Control the mouse cursor enough to be able to do all kinds of stuff, including play games and tweet and all that kind of stuff. And there’s a lot of people for whom life, the basics of life, are difficult because of the things that have happened to them.
DJ Seo
Yeah. I mean, movement is so fundamental to our existence. I mean, even speaking involves movement of mouth, lip, larynx. And without that, it’s extremely debilitating. And there are many, many people that we can help. I mean, especially if you start to look at other forms of movement disorders that are not just from spinal cord injury, but from a ALS, MS, or even stroke, or just aging, that leads you to lose some of that mobility, that independence, it’s extremely debilitating.

And all of these are opportunities to help people, to help alleviate suffering, to help improve the quality of life. But each of the things you mentioned is its own little puzzle that needs to have increasing levels of capability from a device like a Neuralink device.

Digital telepathy
And so the first one you’re focusing on is, it’s just a beautiful word, telepathy. So being able to communicate using your mind wirelessly with a digital device. Can you just explain exactly what we’re talking about?
DJ Seo
Yeah, I mean, it’s exactly that. I mean, I think if you are able to control a cursor and able to click and be able to get access to a computer or a phone, I mean, the whole world opens up to you. And I mean, I guess the word “telepathy,” if you think about that as just definitionally being able to transfer information from my brain to your brain without using some of the physical faculties that we have, like voices.

But the interesting thing here is I think the thing that’s not obviously clear is how exactly it works. In order to move a cursor, there’s at least a couple of ways of doing that. One is you imagine yourself maybe moving a mouse with your hand, or you can then, which no one talked about, imagine moving the cursor with your mind.

But it’s like there is a cognitive step here that’s fascinating, because you have to use the brain and you have to learn how to use the brain, and you have to figure it out dynamically because you reward yourself if it works. I mean, there’s a step that … This is just a fascinating step because you have to get the brain to start firing in the right way. And you do that by imagining … Like fake it till you make it. And all of a sudden it creates the right kind of signal that, if decoded correctly, can create the effect. And then there’s noise around that that you have to figure all of that out. But on the human side, imagine the cursor moving is what you have to do.
DJ Seo
Yeah. He says using the force.
Yeah. He says using the force.
Lex Fridman
The force. I mean, isn’t that just fascinating to you that it works? To me, it’s like, holy shit, that actually works. You could move a cursor with your mind.

As much as you’re learning to use that thing, that thing is also learning about you. Our model’s constantly updating the way to say, “Oh, if someone is thinking about this sophisticated forms of spiking patterns, that actually means to do this.”

So the machine is learning about the human and the human is learning about the machine, so there is a adaptability to the signal process and the decoding step, and then there’s the adaptation of Nolan, the human being. The same way, if you give me a new mouse and I move it, I learn very quickly about its sensitivity, so I learn to move it slower. And then there’s other signal drift and all that kind of stuff they have to adapt to, so both are adapting to each other.

The organic and the inorganic. Anyway. Sorry to rudely interrupt. So there’s the selection that Noland has passed with flying colors. Everything, including that it is a BCI-friendly home, all of that. So what is the process of the surgery, implantation, the first moment when he gets to use the system?

DJ Seo
The end-to-end, we say patient end to patient out, is anywhere between two to four hours. In the particular case for Noland it was about three and a half hours, and there’s many steps leading to the actual robot insertion. So there’s anesthesia induction, and we do intra-op CT imaging to make sure that we’re drilling the hole in the right location. And this is also pre-planned beforehand.

So there’s anesthesia induction, and we do intra-op CT imaging to make sure that we’re drilling the hole in the right location. And this is also pre-planned beforehand.
Someone like Noland would go through fMRI and then they can think about wiggling their hand. Obviously due to their injury it’s not going to actually lead to any sort of intended output, but it’s the same part of the brain that actually lights up when you’re imagining moving your finger to actually moving your finger. And that’s one of the ways in which we can actually know where to place our threads because we want to go into what’s called the hand knob area in the motor cortex. And as much as possible, densely put our electrode threads.
So we do intra-op CT imaging to make sure and double-check the location of the craniectomy. And the surgeon comes in, does their thing in terms of skin incision, craniectomy, so drilling of the skull, and then there’s many different layers of the brain. There’s what’s called a dura, which is a very, very thick layer that surrounds the brain. That gets actually resected in a process called [inaudible 02:32:38]. And that then expose the pia in the brain that you want to insert.
And by the time it’s been around anywhere between one to one and a half hours, robot comes in, does his thing, placement of the targets, inserting of the thread. That takes anywhere between 20 to 40 minutes. In the particular case for Noland, it was just under or just over 30 minutes. And then after that, the surgeon comes in, there’s a couple other steps of actually inserting the dural substitute layer to protect the thread as well as the brain. And then screw in the implant and then skin flap and then suture, and then you’re out.
Lex Fridman
So when Noland woke up, what was that like? What was the recovery like, and when was the first time he was able to use it?
So when Noland woke up, what was that like? What was the recovery like, and when was the first time he was able to use it?
DJ Seo
He was actually immediately after the surgery, like an hour after the surgery, as he was waking up, we did turn on the device, make sure that we are recording neural signals. And we actually did have couple signals that we noticed that he can actually modulate. And what I mean by modulate is that he can think about clenching his fist and you could see the spike disappear and appear.

Obviously there have been other, as you mentioned, pioneers that have participated in these groundbreaking BCI investigational early feasibility studies. So we’re obviously standing on the shoulders of the giants here, we’re not the first ones to actually put electrodes in a human brain.

But I mean, just leading up to the surgery, I definitely could not sleep. It’s the first time that you’re working in a completely new environment. We had a lot of confidence based on our benchtop testing or preclinical R&D studies that the mechanism, the threads, the insertion, all that stuff is very safe and that it’s obviously ready for doing this in a human. But there’s still a lot of unknown unknown about can the needle actually insert? I mean, we brought something like 40 needles just in case they break, and we ended up using only one. But I mean, that was the level of just complete unknown because it’s a very, very different environment. And I mean, that’s why we do clinical trial in the first place, to be able to test these things out.
So extreme nervousness and just many, many sleepless night leading up to the surgery, and definitely the day before the surgery. And it was an early morning surgery. We started at 7:00 in the morning, and by the time it was around 10:30 everything was done. But I mean, first time seeing that, well, number one, just huge relief that this thing is doing what it’s supposed to do. And two, I mean, just immense amount of gratitude for Noland and his family. And then many others that have applied and that we’ve spoken to and will speak to are true pioneers in every word. And I call them the neural astronauts or neuralnaut.
Lex Fridman
Neuralnaut, yeah.
Neuralnaut, yeah.
DJ Seo
Just like in the ’60s, these amazing just pioneers exploring the unknown outwards, in this case it’s inward, but an incredible amount of gratitude for them to just participate and play a part. And it’s a journey that we’re embarking on together.

But also, I think it was just a … That was a very, very important milestone, but our work was just starting. So a lot of just anticipation for, “Okay, what needs to happen next?” What are set of sequences of events that needs to happen for us to make it worthwhile for both Noland as well as us.
Lex Fridman
Just to linger on that, just a huge congratulations to you and the team for that milestone. I know there’s a lot of work left, but that’s really exciting to see. That’s a source of hope, it’s this first big step, opportunity, to help hundreds of thousands of people. And then maybe expand the realm of the possible for the human mind for millions of people in the future. So it’s really exciting. The opportunities are all ahead of us, and to do that safely and to do that effectively was really fun to see. As an engineer, just watching other engineers come together and do an epic thing, that was awesome. So huge congrats.

Thank you, thank you. Yeah, could not have done it without the team. And yeah, I mean, that’s the other thing that I told the team as well of just this immense sense of optimism for the future. I mean, it’s a very important moment for the company, needless to say, as well as hopefully for many others out there that we can help.

Retracted threads
Lex Fridman
Speaking of challenges, Neuralink published a blog post describing that some of the threads retracted. And so the performance as measured by bits per second dropped at first, but then eventually it was regained. And the whole story of how it was regained is super interesting, that’s definitely something I’ll talk to Bliss and to Noland about.

But in general, can you speak to this whole experience, how was the performance regained, and just the technical aspects of the threads being retracted and moving?
DJ Seo
The main takeaway is that in the end, the performance have come back and it’s actually gotten better than it was before. He’s actually just beat the world record yet again last week to 8.5 bps. I mean, he’s just cranking and he’s just improving.

So yeah, so the performance was regained.
DJ Seo
Yeah, better than before. That’s a story on its own of what took the BCI team to recover that performance. It was actually mostly on the signal processing. And so as I mentioned, we were looking at these spike outputs from our electrodes, and what happened is that four weeks into the surgery we noticed that the threads have solely come out of the brain. And the way in which we noticed this at first obviously is that, well, I think Noland was the first to notice, that his performance was degrading. And I think at the time we were also trying to do a bunch of different experimentation, different algorithms, different UI, UX. So it was expected that there will be variability in the performance, but we did see a steady decline.

And I think at the time we were also trying to do a bunch of different experimentation, different algorithms, different UI, UX. So it was expected that there will be variability in the performance, but we did see a steady decline.
And then also the way in which we measure the health of the electrodes or whether they’re in the brain or not, is by measuring impedance of the electrode. So we look at the interfacial, the Randles circuit they say, the capacitance and the resistance between the electrode surface and the medium. And if that changes in some dramatic ways, we have some indication. Or if you’re not seeing spikes on those channels, you have some indications that something’s happening there.
And what we noticed is that looking at those impedance plot and spike rate plots, and also because we have those electrodes recording along the depth, you are seeing some sort of movement that indicated that threads were being pulled out. And that obviously will have an implication on the model side because if the number of inputs that are going into the model is changing because you have less of them, that model needs to get updated.
But there were still signals, and as I mentioned, similar to how even when you place the signals on the surface of the brain or farther away, like outside the skull, you still see some useful signals. What we started looking at is not just the spike occurrence through this BOSS algorithm that I mentioned, but we started looking at just the power of the frequency band that is interesting for Noland to be able to modulate. Once we changed the algorithm for the implant to not just give you the BOSS output, but also these spike band power output, that helped us refine the model with a new set of inputs. And that was the thing that really ultimately gave us the performance back. And obviously the thing that we want ultimately and the thing that we are working towards, is figuring out ways in which we can keep those threads intact for as long as possible so that we have many more channels going into the model. That’s by far the number one priority that the team is currently embarking on to understand how to prevent that from happening.
The thing that I will say also is that, as I mentioned, this is the first time ever that we’re putting these threads in the human brain. And a human brain, just for size reference, is 10 times that of the monkey brain or the sheep brain. And it’s just a very, very different environment. It moves a lot more. It’s actually moved a lot more than we expected when we did Noland’s surgery. And it’s just a very, very different environment than what we’re used to. And this is why we do clinical trial, we want to uncover some of these issues and failure modes earlier than later.
So in many ways, it’s provided us with this enormous amount of data and information to be able to solve this. And this is something that Neuralink is extremely good at, once we have set of clear objective and engineering problem, we have enormous amount of talents across many, many disciplines to be able to come together and fix the problem very, very quickly.
Vertical integration
Lex Fridman
But it sounds like one of the fascinating challenges here is for the system on the decoding side to be adaptable across different timescales. So whether it’s movement of threads or different aspects of signal drift, sort of on the software or the human brain, something changing, like Noland talks about cursor drift, they could be corrected. And there’s a whole UX challenge to how to do that. So it sounds like adaptability is a fundamental property that has to be engineered in.

What are we looking at here, this thing? “In less than one minute, our custom-made femtosecond laser mill cuts this geometry in the tips of our needles.” So we’re looking at this weirdly shaped needle. “The tip is only 10 to 12 microns in width, only slightly larger than the diameter of a red blood cell. The small size allows threads to be inserted with minimal damage to the cortex.”

DJ Seo
This is the needle that’s engaging with the loops in the thread. They’re the ones that thread their loop, and then peel it from the silicon backing, and then this is the thing that gets inserted into the tissue. And then this pulls out, leaving the thread. And this kind of a notch or the shark tooth that we used to call, is the thing that actually is grasping the loop. And then it’s designed in such a way such that when you pull out, it leaves the loop.

Yeah, our robot is quite heavy, our current version of it. I mean, it’s like a giant granite slab that weighs about a ton, because it needs to be sensitive to vibration, environmental vibration. And then as the head is moving at the speed that it’s moving, there’s a lot of motion control to make sure that you can achieve that level of precision. A lot of optics that zoom in on that. We’re working on next generation of the robot that is lighter, easier to transport. I mean, it is a feat to move the robot to the surgical suite.

So continuing the paragraph. “We developed novel hardware and software testing systems, such as our accelerated lifetime testing racks and simulated surgery environment,” which is pretty cool, “to stress test and validate the robustness of our technologies. We performed many rehearsals of our surgeries to refine our procedures and make them second nature.” This is pretty cool.

“We practice surgeries on proxies with all the hardware and instruments needed in our mock or in the engineering space. This helps us rapidly test and measure.” So there’s like proxies?
DJ Seo
Yeah, this proxy is super cool actually. There’s a 3D printed skull from the images that is taken at [inaudible 02:48:34], as well as this hydrogel mix synthetic polymer thing that actually mimics the mechanical properties of the brain. It also has vasculature of the person.

Basically what we’re talking about here, and there’s a lot of work that has gone into making this set proxy, that it’s about finding the right concentration of these different synthetic polymers to get the right set of consistency for the needle dynamics as they’re being inserted. But we practice this surgery with Noland’s basically physiology and brain many, many times prior to actually doing the surgery.
Lex Fridman
Every step, every step, every-
Every step, every step, every-
DJ Seo
Every step. Yeah. Like where does someone stand? I mean, what you’re looking at is the picture, this is in our office, of this corner of the robot engineering space that we have created this mock OR space that looks exactly like what they would experience, all the staff would during their actual surgery.

I mean, what you’re looking at is the picture, this is in our office, of this corner of the robot engineering space that we have created this mock OR space that looks exactly like what they would experience, all the staff would during their actual surgery.
I mean, it’s just like any dance rehearsal where exactly where you’re going to stand at what point, and you just practice that over and over and over again with an exact anatomy of someone that you’re going to surgerize. And it got to a point where a lot of our engineers, when we created a craniectomy, they’re like, “Oh, that looks very familiar. We’ve seen that before.”
Lex Fridman
Yeah. Man, there’s wisdom you can gain through doing the same thing over and over and over. It’s like Jiro Dreams of Sushi kind of thing because then … It’s like Olympic athletes visualize the Olympics and then once you actually show up, it feels easy. It feels like any other day. It feels almost boring winning the gold medal, because you visualized this so many times, you’ve practiced this so many times, that nothing about it is new. It’s boring. You win the gold medal, it’s boring. And the experience they talk about is mostly just relief, probably that they don’t have to visualize it anymore.

Safety
Lex Fridman
I think it’s a good place to actually ask the big question that people might have, is how do we know every aspect of this that you described is safe?

At the end of the day, the gold standard is to look at the tissue. What sort of trauma did you cause the tissue, and does that correlate to whatever behavioral anomalies that you may have seen? And that’s the language to which we can communicate about the safety of inserting something into the brain and what type of trauma that you can cause.

And that’s the language to which we can communicate about the safety of inserting something into the brain and what type of trauma that you can cause.
We actually have an entire department, department of pathology, that looks at these tissue slices. There are many steps that are involved in doing this. Once you have studies that are launched with particular endpoints in mind, at some point you have to euthanize the animal, and then you go through necropsy to collect the brain tissue samples. You fix them in formalin, and you gross them, you section them, and you look at individual slices just to see what kind of reaction or lack thereof exists.
So that’s the language to which FDA speaks and as well for us to evaluate the safety of the insertion mechanism, as well as the threats at various different time points, both acute, so anywhere between zero to three months to beyond three months.
Lex Fridman
So those are the details of an extremely high standard of safety that has to be reached.
So those are the details of an extremely high standard of safety that has to be reached.

Correct.

The FDA supervises this, but there’s in general just a very high standard, in every aspect of this, including the surgery. I think Matthew MacDougall has mentioned that the standard is, let’s say how to put it politely, higher than maybe some other operations that we take for granted. So the standard for all the surgical stuff here is extremely high.

Very high. I mean, it’s a highly, highly regulated environment with the governing agencies that scrutinize every, every medical device that gets marketed. And I think it’s a good thing. It’s good to have those high standards, and we try to hold extremely high standards to understand what sort of damage, if any, these innovative emerging technologies and new technologies that we’re building are. And so far we have been extremely impressed by lack of immune response from these threads.

Speaking of which, you talked to me with excitement about the histology in some of the images that you’re able to share. Can you explain to me what we’re looking at?

DJ Seo
Yeah, so what you’re looking at is a stained tissue image. This is a sectioned tissue slice from an animal that was implanted for seven months, so a chronic time point. And you’re seeing all these different colors, and each color indicates specific types of cell types. So purple and pink are astrocytes and microglia, respectably. They’re types of glial cells.

And the other thing that people may not be aware of is your brain is not just made up of soup of neurons and axons. There are other cells, like glial cells, that actually is the glue and also react if there are any trauma or damage to the tissue.

So what you’re seeing is in this macro image, you’re seeing these circle highlighted in white, the insertion sites. And when you zoom into one of those, you see the threads. And then in this particular case, I think we’re seeing about the 16 wires that are going into the [inaudible 02:54:56]. And the incredible thing here is the fact that you have the neurons that are these brown structures or brown circular or elliptical thing-

DJ Seo
… are these brown structures or brown circular or elliptical thing that are actually touching and abutting the threads. So what this is saying is that there’s basically zero trauma that’s caused during this insertion. And with these neural interfaces, these micro electrons that you insert, that is one of the most common mode of failure. So when you insert these threads like the Utah Array, it causes neuronal death around the site because you’re inserting a foreign object.

And that elicit these immune response through microglia and astrocytes, they form this protective layer around it. Oh, not only are you killing the neuron cells, but you’re also creating this protective layer that then basically prevents you from recording neural signals because you’re getting further and further away from the neurons that you’re trying to record. And that is the biggest mode of failure. And in this particular example, in that inside it’s about 50 micron with that scale bar, the neurons seem to be attracted to it.
Lex Fridman
And so there’s certainly no trauma. That’s such a beautiful image, by the way. So the brown at the neurons, and for some reason I can’t look away. It’s really cool.
And so there’s certainly no trauma. That’s such a beautiful image, by the way. So the brown at the neurons, and for some reason I can’t look away. It’s really cool.
DJ Seo
Yeah. And the way that these things… Tissues generally don’t have these beautiful colors. This is multiplex stain that uses these different proteins that are staining these at different colors. We use very standard set of staining techniques with H&E, EVA1 and NeuN and GFAB. So if you go to the next image, this is also kind of illustrates the second point because you can make an argument, and initially when we saw the previous image, we said, “Oh, are the threads just floating? What is happening here? Are we actually looking at the right thing?” So what we did is we did another stain, and this is all done in-house of this Masson’s tricrome stain, which is in blue that shows these collagen layer. So the blue, basically, you don’t want the blue around the implant threads. Because that means that there’s some sort of scarring that’s happened. And what you’re seeing if you look at individual threads is that you don’t see any of the blue. Which means that there has been absolutely, or very, very minimal to a point where it’s not detectable amount of trauma in these inserted threads.

So that presumably is one of the big benefits of having this kind of flexible thread? This-
So that presumably is one of the big benefits of having this kind of flexible thread? This-
DJ Seo
Yeah. So we think this is primarily due to the size as well as the flexibility of the threads. Also, the fact that R1 is avoiding vasculature, so we’re not disrupting or we’re not causing damage to the vessels and not breaking any of the blood brain barrier, has basically caused the immune response to be muted.

And they’re neurons. And this is the thread listening. And the electrodes are positioned how?
DJ Seo
Yeah. So what you’re looking at is not electrode themselves, those are the conductive wires. So each of those should probably be two micron in width. So what we’re looking at is, we’re looking at the coronal slice, so we’re looking at some slice of the tissue. So as you go deeper, you’ll obviously have less and less of the tapering of the thread. But yeah, the point basically being that there’s just cells around the inserter site, which is just an incredible thing to see. I’ve just never seen anything like this.

Lex Fridman
How easy and safe is it to remove the implant?
How easy and safe is it to remove the implant?
DJ Seo
Yeah, so it depends on when. In the first three months or so after the surgery, there’s a lot of tissue modeling that’s happening. Similar to when you got a cut, you obviously start over first couple of weeks or depending on the size of the wound, scar tissue forming, there are these contractive, and then in the end they turn into scab and you can scab it off. The same thing happens in the brain. And it’s a very dynamic environment. And before the scar tissue or the neo membrane or the new membrane that forms, it’s quite easy to just pull them out. And there’s minimal trauma that’s caused during that.

And there’s minimal trauma that’s caused during that.
Once the scar tissue forms, and with Noland as well, we believe that that’s the thing that’s currently anchoring the threats. So we haven’t seen any more movements since then. So they’re quite stable. It gets harder to actually completely extract the threads. So our current method for removing the device is cutting the thread, leaving the tissue intact, and then unscrewing and taking the implant out. And that hole is now going to be plugged with either another Neuralink or just with a peak based, plastic based cap.
Lex Fridman
Is it okay to leave the threads in there forever?
Is it okay to leave the threads in there forever?
DJ Seo
Yeah, we think so. We’ve done studies where we left them there and one of the biggest concerns that we had is, do they migrate and do they get to a point where they should not be? We haven’t seen that. Again. Once the scar tissue forms, they get anchored in place. And I should also say that when we say upgrades, we’re not just talking in theory here, we’ve actually upgraded many, many times. Most of our monkeys or non-human primates, NHP, have been upgraded. Pager, who you saw playing mind pong has the latest version of the device since two years ago and is seemingly very happy and healthy and fat.

Upgrades
Lex Fridman
So what’s designed for the future, the upgrade procedure? So maybe for Noland, what would the upgrade look like? It was essentially what you’re mentioning. Is there a way to upgrade the device internally where you take it apart and keep the capsule and upgrade the internals?

DJ Seo
So there are a couple of different things here. So for Noland, if we were to upgrade, what we would have to do is either cut the threads or extract the threads depending on the situation there in terms of how they’re anchored or scarred in. If you were to remove them with the dual substitute, you have an intact brain, so you can reinsert different threads with the updated implant package. There are a couple of different other ways that we’re thinking about the future of what the upgradable system looks like. One is, at the moment we currently remove the dura, this kind of thick layer that protects the brain, but that actually is the thing that actually proliferates the scar tissue formation. So typically, the general rule of thumb is you want to leave the nature as is and not disrupt it as much. So looking at ways to insert the threats through the dura, which comes with different set of challenges such as, it’s a pretty thick layer, so how do you actually penetrate that without breaking the needle?

So looking at ways to insert the threats through the dura, which comes with different set of challenges such as, it’s a pretty thick layer, so how do you actually penetrate that without breaking the needle?
So we’re looking at different needle design for that as well as the kind of the loop engagement. The other biggest challenges are, it’s quite opaque, optically with white light illumination. So how do you avoid still this biggest advantage that we have of avoiding vasculature? How do you image through that? How do you actually still mediate that? So there are other imaging techniques that we’re looking at to enable that. But the goal, our hypothesis is that, and based on some of the early evidence that we have, doing through the dura insertion will cause minimal scarring that causes them to be much easier to extract over time. And the other thing that we’re also looking at, this is going to be a fundamental change in the implant architecture, is as at the moment, it’s a monolithic single implant that comes with a thread that’s bonded together.
So you can’t actually separate the thing out, but you can imagine having two part implant, bottom part that is the thread that are inserted that has the chips and maybe a radio and some power source. And then you have another implant that has more of the computational heavy load and the bigger battery. And then one can be under the dura, one can be above the dura being the plug for the skull. They can talk to each other, but the thing that you want to upgrade, the computer and not the thread, if you want to upgrade that, you just go in there, remove the screws, and then put in the next version. And you’re off the… It’s a very, very easy surgery too. You do a skin incision, slip this in, screw. Probably be able to do this in 10 minutes.
Lex Fridman
So that would allow you to reuse the thread sort of?
So that would allow you to reuse the thread sort of?
DJ Seo
Correct.
Correct.
Lex Fridman
So I mean, this leads to the natural question of what is the pathway to scaling the increase in the number of threads? Is that a priority? What’s the technical challenge there?
So I mean, this leads to the natural question of what is the pathway to scaling the increase in the number of threads? Is that a priority? What’s the technical challenge there?
DJ Seo
Yeah, that is a priority. So for next versions of the implant, the key metrics that we’re looking to improve are number of channels, just recording from more and more neurons. We have a pathway to actually go from currently 1000 to hopefully 3000, if not 6,000 by end of this year.

DJ Seo
There’s a couple of limitations to that. One is, obviously being able to photolithographically, print those wires. As I mentioned, it’s two micron in width and spacing. Obviously, there are chips that are much more advanced than those types of resolution and we have some of the tools that we have brought in house to be able to do that. So traces will be narrower just so that you have to have more of the wires coming up into the chip. Chips also cannot linearly consume more energy as you have more and more channels. So there’s a lot of innovations in the circuit, and architecture as well as the circuit design topology to make them lower power. You need to also think about if you have all of these spikes, how do you send that off to the end application. So you need to think about bandwidth limitation there and potentially innovations and signal processing.

So you need to think about bandwidth limitation there and potentially innovations and signal processing.
Physically, one of the biggest challenges is going to be the interface. It’s always the interface that breaks bonding this thin film array to the electronics. It starts to become very, very highly dense interconnects. So how you connectivise that? There’s a lot of innovations in the 3D integrations in the recent years that we can take advantage of. One of the biggest challenges that we do have is forming this hermetic barrier. This is an extremely harsh environment that we’re in, the brain. So how do you protect it from, yeah, the brain trying to kill your electronics, to also your electronics leaking things that you don’t want into the brain. And that forming that hermetic barrier is going to be a very, very big challenge that we, I think are actually well suited to tackle.
Lex Fridman
How do you test that? What’s the development environment to simulate that kind of harshness?
How do you test that? What’s the development environment to simulate that kind of harshness?
DJ Seo
Yeah, so this is where the accelerated life tester essentially is a brain in a vat. It literally is a vessel that is made up of, and again, for all intents and purpose for this particular type of test, your brain is a salt water. And you can also put some other set of chemicals like reactive oxygen species that get at these interfaces and trying to cause a reaction to pull it apart. But you could also increase the rate at which these interfaces are aging by just increasing temperature. So every 10 degrees Celsius that you increase, you’re basically accelerating time by two X.

But you could also increase the rate at which these interfaces are aging by just increasing temperature. So every 10 degrees Celsius that you increase, you’re basically accelerating time by two X.
And there’s limit as to how much temperature you want to increase because at some point there’s some other nonlinear dynamics that causes you to have other nasty gases to form that just is not realistic in an environment. So what we do is we increase in our ALT chamber by 20 degrees Celsius that increases the aging by four times. So essentially one day in ALT chamber is four day in calendar year, and we look at whether the implants still are intact, including the threats. And-
Lex Fridman
And operation and all of that.
And operation and all of that.
DJ Seo
… and operation and all of that. Obviously, is not an exact same environment as a brain because brain has mechanical other more biological groups that attack at it. But it is a good test environment, testing environment for at least the enclosure and the strength of the enclosure. And I mean, we’ve had implants, the current version of the implant that has been in there for close to two and a half years, which is equivalent to a decade and they seem to be fine.

By the way, I’m drinking LMNT , which is basically salt water. Which is making me kind of… It doesn’t have computational power the way the brain does, but maybe in terms of other characteristics, it’s quite similar and I’m consuming it.

DJ Seo
By the way, the other thing that also is interesting about our enclosure is, if you look at our implant, it’s not your common looking medical implant that usually is encased in a titanium can that’s laser welded. We use this polymer called PCTFE, polychlorotrifluoroethylene, which is actually commonly used in blister packs. So when you have a pill and you try to pop a pill, there’s kind of that plastic membrane. That’s what this is. No one’s actually ever used this except us. And the reason we wanted to do this is because electromagnetically transparent. So when we talked about the electromagnetic inductive charging, with titanium can usually if you want to do something like that, you have to have a sapphire window and it’s a very, very tough process to scale.

DJ Seo
Absolutely. That’s the goal. And we talk about at Neuralink building a generalized neural interface to the brain. And that also is strategically how we’re approaching this with marketing and also with regulatory, which is, hey, look, we have the robot and the robot can access any part of the cortex. Right now we’re focused on motor cortex with current version of the N1 that’s specialized for motor decoding tasks. But also at the end of the day, there’s a general compute available there. But typically if you want to really get down to hyperoptimizing for power and efficiency, you do need to get to some specialized function.

But what we’re saying is that, hey, you are now used to this robotic insertion techniques, which took many, many years of showing data and conversation with the FDA and also internally convincing ourselves that this is safe. And now the difference is if we go to other parts of the brain, like visual cortex, which we’re interested in as our second product, obviously it’s a completely different environment, the cortex is laid out very, very differently. It’s going to be more stimulation focus rather than recording, just kind of creating visual percepts. But in the end, we’re using the same thin film array technology, we’re using the same robot insertion technology, we’re using the same packaging technology. Now it’s where the conversation is focused around what are the differences and what are the implication of those differences in safety and efficacy.
Lex Fridman
The way you said second product is both hilarious and awesome to me. That product being restoring sight for blind people. So can you speak to stimulating the visual cortex? I mean, the possibilities there are just incredible to be able to give that gift back to people who don’t have sight or even any aspect of that. Can you just speak to the challenges of… There’s challenges here-

One of which is like you said, from recording to stimulation. Just any aspect of that that you’re both excited and see the challenges of?
DJ Seo
Yeah, I guess I’ll start by saying that we actually have been capable of stimulating through our thin film array as well as other electronics for years. We have actually demonstrated some of that capabilities for reanimating the limb in the spinal cord. Obviously, for the current EFS study, we’ve hardware disabled that. So that’s something that we wanted to embark as a separate journey. And obviously, there are many, many different ways to write information into the brain. The way in which we’re doing that is through electrical, passing electrical current, and kind of causing that to really change the local environment so that you can artificially cause the neurons to depolarize in nearby areas. For vision, specifically the way our visual system works, it’s both well understood. I mean, anything with kind of brain, there are aspects of it that’s well understood, but in the end, we don’t really know anything.

I mean, anything with kind of brain, there are aspects of it that’s well understood, but in the end, we don’t really know anything.
But the way visual system works is that you have photon hitting your eye, and in your eyes there are these specialized cells called photoreceptor cells that convert the photon energy into electrical signals. And then that then gets projected to your back of your head, your visual cortex. It goes through actually thalamic system called LGN that then projects it out. And then in the visual cortex there’s visual area one or V1, and then there’s a bunch of other higher level processing layers like V2, V3. And there are actually kind of interesting parallels. And when you study the behaviors of these convolutional neural networks, like what the different layers of the network is detecting, first they’re detecting these edges and they’re then detecting some more natural curves and then they start to detect objects.
Kind of similar thing happens in the brain. And a lot of that has been inspired and also it’s been kind of exciting to see some of the correlations there. But things like from there, where does cognition arise and where’s color encoded? There’s just not a lot of understanding, fundamental understanding there. So in terms of bringing sight back to those that are blind, there are many different forms of blindness. There’s actually million people, 1 million people in the US that are legally blind. That means certain score below in the visual tests. I think it’s something like if you can see something at 20 feet distance that normal people can see at 200 feet distance, if you’re worse than that, you’re legally blind.
Lex Fridman
So fundamental that means you can’t function effectively using sight in the world.

… you’re environment. And yeah, there are different forms of blindness. There are forms of blindness where there’s some degeneration of your retina is photoreceptor cells and rest of your visual processing that I described is intact. And for those types of individuals, you may not need to maybe stick electrodes into the visual cortex. You can actually build retinal prosthetic devices that actually just replaces the function of that retinal cells that are degenerated. And there are many companies that are working on that, but that’s a very small slice albeit significance, those smaller slice of folks that are legally blind.

If there’s any damage along that circuitry, whether it’s in the optic nerve or just the LGN circuitry or any break in that circuit, that’s not going to work for you. And the source of where you need to actually cause that visual percepts to happen because your biological mechanism not doing that is by placing electrodes in the visual cortex in the back of your head. And the way in which this would work is that you would have an external camera, whether it’s something as unsophisticated as a GoPro or some sort of wearable Ray- Ban type glasses that meta is working on that captures a scene. And that scene is then converted to a set of electrical impulses or stimulation pulses that you would activate in your visual cortex through these thin film arrays. And by playing some a concerted kind of orchestra of these stimulation patterns, you can create what’s called phosphenes, which are these kind of white yellowish dots that you can also create by just pressing your eyes. You can actually create those percepts by stimulating the visual cortex.
And the name of the game is really have many of those and have those percepts, be the phosphenes, be as small as possible so that you can start to tell apart they’re the individual pixels of the screen. So if you have many, many of those potentially you’ll be able to, in the long term, be able to actually get naturalistic vision. But in the short term to maybe midterm, being able to at least, be able to have object detection algorithms run on your glasses, the pre-processing units, and then being able to at least see the edges of things so you don’t bump into stuff.
Lex Fridman
This is incredible. This is really incredible. So you basically would be adding pixels and your brain would start to figure out what those pixels mean with different kinds of assistant signal processing on all fronts.

DJ Seo
Yeah. The thing that actually… So a couple of things. One is obviously if you’re blind from birth, the way brain works, especially in the early age, neuroplasticity is really nothing other than your brain and different parts of your brain fighting for the limited territory. And I mean very, very quickly you see cases where people that are… I mean, you also hear about people who are blind that have heightened sense of hearing or some other senses. And the reason for that is because that cortex that’s not used just gets taken over by these different parts of the cortex. So for those types of individuals, I mean I guess they’re going to have to now map some other parts of their senses into what they call vision, but it’s going to be obviously a very, very different conscious experience.

Before… So I think that’s an interesting caveat. The other thing that also is important to highlight is that, we’re currently limited by our biology in terms of the wavelength that we can see. There’s a very, very small wavelength that is a visible light wavelength that we can see with our eyes. But when you have an external camera with this BCI system, you’re not limited to that. You can have infrared, you can have UV, you can have whatever other spectrum that you want to see. And whether that gets matched to some sort of weird conscious experience, I’ve no idea. But oftentimes I talk to people about the goal of Neuralink being going beyond the limits of our biology. That’s sort of what I mean.
Lex Fridman
And if you’re able to control the kind of raw signal, is that when we use our site, we’re getting the photons and there’s not much processing on it. If you’re being able to control that signal, maybe you can do some kind of processing, maybe you do object detection ahead of time. You’re doing some kind of pre-processing and there’s a lot of possibilities to explore that. So it’s not just increasing thermal imaging, that kind of stuff, but it’s also just doing some kind of interesting processing.

DJ Seo
Correct. Yeah. I mean, my theory of how visual system works also is that, I mean, there’s just so many things happening in the world and there’s a lot of photons that are going into your eye. And it’s unclear exactly where some of the pre-processing steps are happening. But I mean, I actually think that just from a fundamental perspective, there’s just so much the reality that we’re in, if it’s a reality, so there’s so much data and I think humans are just unable to actually eat enough, actually to process all that information. So there’s some sort of filtering that does happen, whether that happens in the retina, whether that happens in different layers of the visual cortex, unclear. But the analogy that I sometimes think about is, if your brain is a CCD camera and all of the information in the world is a sun, and when you try to actually look at the sun with the CCD camera, it’s just going to saturate the sensors because it’s an enormous amount of energy.

So what you do is you end up adding these filters to just kind of narrow the information that’s coming to you and being captured. And I think things like our experiences or our drugs like propofol, anesthetics drug or psychedelics, what they’re doing is they’re kind of swapping out these filters and putting in new ones or removing older ones and kind of controlling our conscious experience.
Lex Fridman
Yeah, man, not to distract from the topic, but I just took a very high dose of ayahuasca in the Amazon jungle. So yes, it’s a nice way to think about it. You’re swapping out different experiences and with Neuralink being able to control that, primarily at first to improve function, not for entertainment purposes or enjoyment purposes, but-

Yeah, I think even with our early participants, if they start to do things that I can’t do, which I think is in the realm of possibility for them to be able to get 15, 20 if not like a hundred BPS. There’s nothing that fundamentally stops us from being able to achieve that type of performance. I mean, I would certainly get jealous that they can do that.

DJ Seo
Yeah. I mean the thing that also is hard to appreciate sometimes is that, he’s doing these things while talking. And I mean, it’s multitasking, so it’s clearly, it’s obviously cognitively intensive. But similar to how when we talk, we move our hands. These are multitasking. I mean, he’s able to do that. And you won’t be able to do that with other assistive technology. As far as I am aware, if you’re obviously using an eye tracking device, you’re very much fixated on that thing that you’re trying to do. And if you’re using voice control, I mean if you say some other stuff, you don’t get to use that.

The multitasking aspect of that is really interesting. So it’s not just the BPS for the primary task, it’s the parallelization of multiple tasks. If you measure the BPS for the entirety of the human organism. So you’re talking and doing a thing with your mind and looking around also, I mean, there’s just a lot of parallelization that can be happening.

But I mean, I think at some point for him, if he wants to really achieve those high level BPS, it does require a full attention. And that’s a separate circuitry that is a big mystery, how attention works and…

Yeah, attention, cognitive load. I’ve read a lot of literature on people doing two tasks. You have your primary task and a secondary task, and the secondary task is a source of distraction. And how does that affect the performance of the primary task? And depending on the tasks, because there’s a lot of interesting… I mean, this is an interesting computational device, and I think there’s-

… a lot of novel insights that can be gained from everything. I mean, I personally am surprised that no one’s able to do such incredible control of the cursor while talking. And also being nervous at the same time because he’s talking like all of us are if you’re talking in front of the camera, you get nervous. So all of those are coming into play and he’s able to still achieve high performance. Surprising. I mean, all of this is really amazing. And I think just after researching this really in depth, I kind of want a Neuralink.

That’d be a separate line for people. They’re just curious like myself. So now that Noland, patient P1 is part of the ongoing prime study, what’s the high level vision for P2, P3, P4, P5, and just the expansion into other human beings that are getting to experience this implant?

DJ Seo
Yeah, I mean the primary goal is for our study in the first place is to achieve safety endpoints. Just understand safety of this device as well as the implantation process. And also at the same time understand the efficacy and the impact that it could have on the potential user’s lives. And Just because you have, you’re living with tetraplegia, it doesn’t mean your situation is same as another person living with tetraplegia. It’s wildly, wildly varying. And it’s something that we’re hoping to also understand how our technology can serve not just a very small slice of those individuals, but broader group of individuals and being able to get the feedback to just really build just the best product for them.

So there’s obviously, also goals that we have. And the primary purpose of the early feasibility study is to learn from each and every participant to improve the device, improve the surgery before we embark on what’s called a pivotal study. That then is a much larger trial that starts to look at statistical significance of your endpoints and that’s required before you can then market the device. And that’s how it works in the US and just generally around the world. That’s the process you follow.
So our goal is to really just understand from people like Noland, P2, P3, future participants, what aspects of our device needs to improve. If it turns out that people are like, “I really don’t like the fact that it lasts only six hours. I want to be able to use this computer for 24 hours.” I mean, that is a user needs and user requirements, which we can only find out from just being able to engage with them.
Lex Fridman
So before the pivotal study, there’s kind of a rapid innovation based on individual experiences. You’re learning from individual people, how they use it, the high resolution details in terms of cursor control and signal and all that kind of stuff, life experience.

DJ Seo
So there’s hardware changes, but also just firmware updates. So even when we had that sort of recovery event for Noland, he now has the new firmware that he has been updated with, and similar to how your phones get updated all the time with new firmware for security patches, whatever, new functionality, UI. And that’s something that is possible with our implant. It’s not a static one-time device that can only do…

DJ Seo
It’s not a static one-time device that can only do the thing that it said it can do. I mean, it’s similar to Tesla, you can do over-the-air firmware updates, and now you have completely new user interface and all these bells and whistles and improvements on everything, like the latest. Right? When we say generalized platform, that’s what we’re talking about.

Yeah. It’s really cool how the app that Noland is using, there’s calibration, all that kind of stuff, and then there’s update. You just click and get an update.

What other future capabilities are you looking to? You said vision. That’s a fascinating one. What about accelerated typing or speech, or this kind of stuff? And what else is there?
DJ Seo
Yeah. Those are still in the realm of movement program. So, largely speaking, we have two programs. We have the movement program and we have the vision program. The movement program currently is focused around the digital freedom. As you can easily guess, if you can control 2D cursor in the digital space, you could move anything in the physical space. So, robotic arms, wheelchair, your environment, or even really, whether it’s through the phone or just directly to those interfaces, to those machines.

So, we’re looking at ways to expand those types of capability, even for Noland. That requires conversation with the FDA and showing safety data for if there’s a robotic arm or a wheelchair, that we can guarantee that they’re not going to hurt themselves accidentally. Right? It’s very different if you’re moving stuff in the digital domain versus in the physical space, you can actually potentially cause harm to the participants. So, we’re working through that right now.
Speech does involve different areas of the brain. Speech prosthetic is very, very fascinating and there’s actually been a lot of really amazing work that’s been happening in academia. Sergey Stavisky at UC Davis, Jaimie Henderson and late Krishna Shenoy at Stanford, are doing just some incredible amount of work in improving speech neuro-prosthetics. And those are actually looking more at parts of the motor cortex that are controlling these vocal articulators, and being able to, even by mouthing the word or imagine speech, you can pick up those signals.
The more sophisticated higher level processing areas like the Broca’s area or Wernicke’s area, those are still very, very big mystery in terms of the underlying mechanism of how all that stuff works. But I mean, I think Neuralink’s eventual goal is to understand those things and be able to provide a platform and tools to be able to understand that and study that.
Lex Fridman
This is where I get to the pothead questions. Do you think we can start getting insight into things like thought? So, speech, there’s a muscular component, like you said, there’s the act of producing sounds, but then what about the internal things like cognition, like low-level thoughts and high-level thoughts? Do you think we’ll start noticing signals that could be picked up, they could be understood, that could be maybe used in order to interact with the outside world?

DJ Seo
In some ways, I guess, this starts to kind of get into the hard problem of consciousness. And I mean, on one hand, all of these are at some point, set of electrical signals that from there maybe it in itself is giving you the cognition or the meaning, or somehow human mind is an incredibly amazing storytelling machine. So, we’re telling ourselves and fooling ourselves that there’s some interesting meaning here.

So, we’re telling ourselves and fooling ourselves that there’s some interesting meaning here.
But I mean, I certainly think that BCI … Really, BCI, at the end of the day is a set of tools that help you study the underlying mechanisms in a both local but also broader sense, and whether there’s some interesting patterns of electrical signal that means you’re thinking this versus … And you can either learn from many, many sets of data to correlate some of that and be able to do mind reading or not. I’m not sure.
I certainly would not rule that out as a possibility, but I think BCI alone probably can’t do that. There’s probably additional set of tools and framework and also just hard problem of consciousness, at the end of the day, is rooted in this philosophical question of what is the meaning of it all? What’s the nature of our existence? Where’s the mind emerged from this complex network?
Lex Fridman
Yeah. How does the subjective experience emerge from just a bunch of spikes, electrical spikes?
Yeah. How does the subjective experience emerge from just a bunch of spikes, electrical spikes?
DJ Seo
Yeah. Yeah. I mean, we do really think about BCI and what we’re building as a tool for understanding the mind, the brain. The only question that matters.
Yeah. Yeah. I mean, we do really think about BCI and what we’re building as a tool for understanding the mind, the brain. The only question that matters.
There actually is some biological existence proof of what it would take to kind of start to form some of these experiences that may be unique. If you actually look at every one of our brains, there are two hemispheres. There’s a left-sided brain, there’s a right-sided brain. And unless you have some other conditions, you normally don’t feel like left legs or right legs, you just feel like one legs, right? So, what is happening there? Right?
If you actually look at the two hemispheres, there’s a structure that kind of connectorized the two, called the corpus callosum, that is supposed to have around 200 to 300 million connections or axons. So, whether that means that’s the number of interface and electrodes that we need to create some sort of mind meld or from that whatever new conscious experience that you can experience. But I do think that there’s kind of an interesting existence proof that we all have.
Lex Fridman
And that threshold is unknown at this time?
And that threshold is unknown at this time?
DJ Seo
Oh, yeah. Everything in this domain is speculation. Right?

And then, you’d be continuously pleasantly surprised. Do you see a world where there is millions of people, like tens of millions, hundreds of millions of people walking around with a Neuralink device or multiple Neuralink devices in their brain?

I do. First of all, there are, if you look at worldwide, people suffering from movement disorders and visual deficits, I mean, that’s in the tens if not hundreds of millions of people. So, that alone, I think there’s a lot of benefit and potential good that we can do with this type of technology. And once you start to get into psychiatric application, depression, anxiety, hunger or obesity, right? Mood, control of appetite. I mean, that starts to become very real to everyone.

Not to mention that most people on Earth have a smartphone, and once BCI starts competing with a smartphone as a preferred methodology of interacting with the digital world, that also becomes an interesting thing.

Oh yeah, this is even before going to that, right? There’s almost, I mean, the entire world that could benefit from these types of things. And then, if we’re talking about next generation of how we interface with machines or even ourselves, in many ways, I think BCI can play a role in that. And some of the things that I also talk about is, I do think that there is a real possibility that you could see 8 billion people walking around with Neuralink.

Well, thank you so much for pushing ahead. And I look forward to that exciting future.

When did you first become fascinated with the human brain?
Matthew MacDougall
Since forever. As far back as I can remember, I’ve been interested in the human brain. I mean, I was a thoughtful kid and a bit of an outsider, and you sit there thinking about what the most important things in the world are in your little tiny adolescent brain. And the answer that I came to, that I converged on was that all of the things you can possibly conceive of as things that are important for human beings to care about are literally contained in the skull. Both the perception of them and their relative values and the solutions to all our problems, and all of our problems, are all contained in the skull. And if we knew more about how that worked, how the brain encodes information and generates desires and generates agony and suffering, we could do more about it.

And if we knew more about how that worked, how the brain encodes information and generates desires and generates agony and suffering, we could do more about it.
You think about all the really great triumphs in human history. You think about all the really horrific tragedies. You think about the Holocaust, you think about any prison full of human stories, and all of those problems boil down to neurochemistry. So, if you get a little bit of control over that, you provide people the option to do better. In the way I read history, the way people have dealt with having better tools is that they most often, in the end, do better, with huge asterisks. But I think it’s an interesting, a worthy, a noble pursuit to give people more options, more tools.
Lex Fridman
Yeah, that’s a fascinating way to look at human history. You just imagine all these neurobiological mechanisms, Stalin, Hitler, Genghis Khan, all of them just had a brain, just a bunch of neurons, few times of billions of neurons gaining a bunch of information over a period of time. They have a set of modules that does language and memory and all that. And from there, in the case of those people, they’re able to murder millions of people. And all that coming from … There’s not some glorified notion of a dictator of this enormous mind or something like this. It’s just the brain.

Lex Fridman
Other brains.
Other brains.
Matthew MacDougall
Yeah. And so, I always find it interesting to look to primatology, look to our closest non-human relatives for clues as to how humans are going to behave and what particular humans are able to achieve. And so, you look at chimpanzees and bonobos, and they’re similar but different in their social structures particularly. And I went to Emory in Atlanta and studied under the great Frans de Waal, who was kind of the leading primatologist, who recently died. And his work looking at chimps through the lens of how you would watch an episode of Friends and understand the motivations of the characters interacting with each other. He would look at a chimp colony and basically apply that lens. I’m massively oversimplifying it.

If you do that, instead of just saying, “Subject 473 threw his feces at subject 471.” You talk about them in terms of their human struggles, accord them the dignity of themselves as actors with understandable goals and drives, what they want out of life. And primarily, it’s the things we want out of life, food, sex, companionship, power. You can understand chimp and bonobo behavior in the same lights much more easily. And I think doing so gives you the tools you need to reduce human behavior from the kind of false complexity that we layer onto it with language, and look at it in terms of, oh, well, these humans are looking for companionship, sex, food, power. And I think that that’s a pretty powerful tool to have in understanding human behavior.
Lex Fridman
And I just went to the Amazon jungle for a few weeks and it’s a very visceral reminder that a lot of life on Earth is just trying to get laid. They’re all screaming at each other. I saw a lot of monkeys and they’re just trying to impress each other, or maybe if there’s a battle for power, but a lot of the battle for power has to do with them getting laid.

Right. Breeding rights often go with alpha status. And so, if you can get a piece of that, then you’re going to do okay.

And we’d like to think that we’re somehow fundamentally different, and especially when it comes to primates, we really aren’t. We can use fancier poetic language, but maybe some of the underlying drives and motivators are similar.

Matthew MacDougall
Basically, the moment I got to college, I started looking around for labs that I could do neuroscience work in. I originally approached that from the angle of looking at interactions between the brain and the immune system, which isn’t the most obvious place to start, but I had this idea at the time that the contents of your thoughts would have a direct impact, maybe a powerful one, on non-conscious systems in your body. The systems we think of as homeostatic automatic mechanisms, like fighting off a virus, like repairing a wound. And sure enough, there are big crossovers between the two.

The systems we think of as homeostatic automatic mechanisms, like fighting off a virus, like repairing a wound. And sure enough, there are big crossovers between the two.
I mean, it gets to kind of a key point that I think goes under-recognized. One of the things people don’t recognize or appreciate about the human brain enough, and that is that it basically controls or has a huge role in almost everything that your body does. You try to name an example of something in your body that isn’t directly controlled or massively influenced by the brain, and it’s pretty hard. I mean, you might say like bone healing or something. But even those systems, the hypothalamus and pituitary end up playing a role in coordinating the endocrine system, that does have a direct influence on say, the calcium level in your blood, that goes to bone healing. So, non-obvious connections between those things implicate the brain as really a potent prime mover in all of health.
Lex Fridman
One of the things I realized in the other direction too, how most of the systems in the body are integrated with the human brain, they affect the brain also, like the immune system. I think there’s just, people who study Alzheimer’s and those kinds of things, it’s just surprising how much you can understand of that from the immune system, from the other systems that don’t obviously seem to have anything to do with the nervous system. They all play together.

Matthew MacDougall
Yeah, you could understand how that would be driven by evolution too. Just in some simple examples, if you get sick, if you get a communicable disease, you get the flu, it’s pretty advantageous for your immune system to tell your brain, “Hey, now be antisocial for a few days. Don’t go be the life of the party tonight. In fact, maybe just cuddle up somewhere warm, under a blanket, and just stay there for a day or two.” And sure enough, that tends to be the behavior that you see both in animals and in humans. If you get sick, elevated levels of interleukins in your blood and TNF-alpha in your blood, ask the brain to cut back on social activity and even moving around, you have lower locomotor activity in animals that are infected with viruses.

So, from there, the early days in neuroscience to surgery, when did that step happen? Which is a leap.

Matthew MacDougall
Yeah. It was sort of an evolution of thought. I wanted to study the brain. I started studying the brain in undergrad in this neuroimmunology lab. I, from there, realized at some point that I didn’t want to just generate knowledge. I wanted to affect real changes in the actual world, in actual people’s lives. And so, after having not really thought about going into medical school, I was on a track to go into a PhD program. I said, “Well, I’d like that option. I’d like to actually potentially help tangible people in front of me.”

And so, after having not really thought about going into medical school, I was on a track to go into a PhD program. I said, “Well, I’d like that option. I’d like to actually potentially help tangible people in front of me.”
And doing a little digging, found that there exists these MD-PhD programs where you can choose not to choose between them and do both. And so, I went to USC for medical school and had a joint PhD program with Caltech, where I actually chose that program particularly because of a researcher at Caltech named Richard Andersen, who’s one of the godfathers of primate neuroscience, and has a macaque lab where Utah arrays and other electrodes were being inserted into the brains of monkeys to try to understand how intentions were being encoded in the brain.
So, I ended up there with the idea that maybe I would be a neurologist and study the brain on the side. And then discovered that neurology … Again, I’m going to make enemies by saying this, but neurology predominantly and distressingly to me, is the practice of diagnosing a thing and then saying, “Good luck with that. There’s not much we can do.” And neurosurgery, very differently, it’s a powerful lever on taking people that are headed in a bad direction and changing their course in the sense of brain tumors that are potentially treatable or curable with surgery. Even aneurysms in the brain, blood vessels that are going to rupture, you can save lives, really, is at the end of the day what mattered to me.
And so, I was at USC, as I mentioned, that happens to be one of the great neurosurgery programs. And so, I met these truly epic neurosurgeons, Alex Khalessi, and Mike Apuzzo, and Steve Giannotta, and Marty Weiss, these epic people that were just human beings in front of me. And so, it kind of changed my thinking from neurosurgeons are distant gods that live on another planet and occasionally come and visit us, to these are humans that have problems and are people, and there’s nothing fundamentally preventing me from being one of them. And so, at the last minute in medical school, I changed gears from going into a different specialty and switched into neurosurgery, which cost me a year. I had to do another year of research because I was so far along in the process that to switch into neurosurgery, the deadlines had already passed. So, it was a decision that cost time, but absolutely worth it.
Neurosurgery
Lex Fridman
What was the hardest part of the training on the neurosurgeon track?
What was the hardest part of the training on the neurosurgeon track?
Matthew MacDougall
Yeah, two things, I think, that residency in neurosurgery is sort of a competition of pain, of how much pain can you eat and smile? And so, there’s work hour restrictions that are not really … They’re viewed, I think, internally among the residents as weakness. And so, most neurosurgery residents try to work as hard as they can, and that, I think necessarily means working long hours and sometimes over the work hour limits.

We care about being compliant with whatever regulations are in front of us, but I think more important than that, people want to give their all in becoming a better neurosurgeon because the stakes are so high. And so, it’s a real fight to get residents to say, go home at the end of their shift and not stay and do more surgery.

Are you seriously saying one of the hardest things is literally forcing them to get sleep and rest and all this kind of stuff?

It’s competitive, and it’s also, as we touched on earlier, primates like power. And I think neurosurgery has long had this aura of mystique and excellence and whatever about it. And so, it’s an invitation, I think, for people that are cloaked in that authority. A board certified neurosurgeon is basically a walking fallacious appeal to authority. Right? You have license to walk into any room and act like you’re an expert on whatever. And fighting that tendency is not something that most neurosurgeons do well. Humility isn’t the forte.

Lex Fridman
Yeah. I have friends who know you and whenever they speak about you that you have the surprising quality for a neurosurgeon of humility, which I think indicates that it’s not as common as perhaps in other professions, because there is a kind of gigantic sort of heroic aspect to neurosurgery, and I think it gets to people’s head a little bit.

Matthew MacDougall
Yeah. Well, I think that allows me to play well at an Elon company because Elon, one of his strengths, I think, is to just instantly see through fallacy from authority. So, nobody walks into a room that he’s in and says, “Well, goddammit, you have to trust me. I’m the guy that built the last 10 rockets,” or something. And he says, “Well, you did it wrong and we can do it better.” Or, “I’m the guy that kept Ford alive for the last 50 years. You listen to me on how to build cars.” And he says, “No.”

And so, you don’t walk into a room that he’s in and say, “Well, I’m a neurosurgeon. Let me tell you how to do it.” He’s going to say, “Well, I’m a human being that has a brain. I can think from first principles myself. Thank you very much. And here’s how I think it ought to be done. Let’s go try it and see who’s right.” And that’s proven, I think over and over in his case, to be a very powerful approach.
Lex Fridman
If we just take that tangent, there’s a fascinating interdisciplinary team at Neuralink that you get to interact with, including Elon. What do you think is the secret to a successful team? What have you learned from just getting to observe these folks, world experts in different disciplines work together?

Matthew MacDougall
There’s a sweet spot where people disagree and forcefully speak their mind and passionately defend their position, and yet, are still able to accept information from others and change their ideas when they’re wrong. And so, I like the analogy of how you polish rocks. You put hard things in a hard container and spin it. People bash against each other, and out comes a more refined product. And so, to make a good team at Neuralink, we’ve tried to find people that are not afraid to defend their ideas passionately and occasionally strongly disagree with people that they’re working with, and have the best idea come out on top.

It’s not an easy balance. Again, to refer back to the primate brain. It’s not something that is inherently built into the primate brain to say, “I passionately put all my chips on this position, and now I’m just going to walk away from it and admit you are right.” Part of our brains tell us that that is a power loss, that is a loss of face, a loss of standing in the community, and now you’re a zeta chump because your idea got trounced. And you just have to recognize that that little voice in the back of your head is maladaptive and it’s not helping the team win.
Lex Fridman
Yeah, you have to have the confidence to be able to walk away from an idea that you hold on to. Yeah.
Yeah, you have to have the confidence to be able to walk away from an idea that you hold on to. Yeah.

Matthew MacDougall
Yeah. I think working your ass off, working hard while functioning as a member of a team, getting a job done that is incredibly difficult, working incredibly long hours, being up all night, taking care of someone that you think probably won’t survive no matter what you do. Working hard to make people that you passionately dislike look good the next morning.

These folks were relentless in their pursuit of excellent neurosurgical technique, decade over decade, and I think were well-recognized for that excellence. So, especially Marty Weiss, Steve Giannotta, Mike Apuzzo, they made huge contributions not only to surgical technique, but they built training programs that trained dozens or hundreds of amazing neurosurgeons. I was just lucky to be in their wake.
Lex Fridman
What’s that like … You mentioned doing a surgery where the person is likely not to survive. Does that wear on you?
What’s that like … You mentioned doing a surgery where the person is likely not to survive. Does that wear on you?
Matthew MacDougall
Yeah. It’s especially challenging when you … With all respect to our elders, it doesn’t hit so much when you’re taking care of an 80-year-old, and something was going to get them pretty soon anyway. And so, you lose a patient like that, and it was part of the natural course of what is expected of them in the coming years, regardless.
Yeah. It’s especially challenging when you … With all respect to our elders, it doesn’t hit so much when you’re taking care of an 80-year-old, and something was going to get them pretty soon anyway. And so, you lose a patient like that, and it was part of the natural course of what is expected of them in the coming years, regardless.
Taking care of a father of two or three, four young kids, someone in their 30s that didn’t have it coming, and they show up in your ER having their first seizure of their life, and lo and behold, they’ve got a huge malignant inoperable or incurable brain tumor. You can only do that, I think, a handful of times before it really starts eating away at your armor. Or, a young mother that shows up that has a giant hemorrhage in her brain that she’s not going to survive from. And they bring her four-year-old daughter in to say goodbye one last time before they turn the ventilator off. The great Henry Marsh is an English neurosurgeon who said it best, I think. He says, “Every neurosurgeon carries with them a private graveyard.” And I definitely feel that, especially with young parents, that kills me. They had a lot more to give. The loss of those people specifically has a knock-on effect that’s going to make the world worse for people for a long time. And it’s just hard to feel powerless in the face of that. And that’s where I think you have to be borderline evil to fight against a company like Neuralink or to constantly be taking pot shots at us, because what we’re doing is to try to fix that stuff. We’re trying to give people options to reduce suffering. We’re trying to take the pain out of life that broken brains brings in. And yeah, this is just our little way that we’re fighting back against entropy, I guess.
Lex Fridman
Yeah. The amount of suffering that’s endured when some of the things that we take for granted that our brain is able to do is taken away, is immense. And to be able to restore some of that functionality is a real gift.
Yeah. The amount of suffering that’s endured when some of the things that we take for granted that our brain is able to do is taken away, is immense. And to be able to restore some of that functionality is a real gift.

Well, can you take me through the full procedure for implanting, say, the N1 chip in Neuralink?
Well, can you take me through the full procedure for implanting, say, the N1 chip in Neuralink?
Matthew MacDougall
Sure. Yeah. It’s a really simple, straightforward procedure. The human part of the surgery that I do is dead simple. It’s one of the most basic neurosurgery procedures imaginable. And I think there’s evidence that some version of it has been done for thousands of years. That there are examples, I think, from ancient Egypt of healed or partially healed trepanations, and from Peru or ancient times in South America where these proto-surgeons would drill holes in people’s skulls, presumably to let out the evil spirits, but maybe to drain blood clots. And there’s evidence of bone healing around the edge, meaning the people at least survived some months after a procedure.

And so, what we’re doing is that. We are making a cut in the skin on the top of the head over the area of the brain that is the most potent representation of hand intentions. And so, if you are an expert concert pianist, this part of your brain is lighting up the entire time you’re playing. We call it the hand knob.
Lex Fridman
The hand knob. So, it’s all the finger movements, all of that is just firing away.
The hand knob. So, it’s all the finger movements, all of that is just firing away.
Matthew MacDougall
Yep. There’s a little squiggle in the cortex right there. One of the folds in the brain is kind of doubly folded right on that spot. And so, you can look at it on an MRI and say, “That’s the hand knob.” And then you do a functional test and a special kind of MRI called a functional MRI, fMRI. And this part of the brain lights up when-

MRI, fMRI, and this part of the brain lights up when people, even quadriplegic people whose brains aren’t connected to their finger movements anymore, they imagine finger movements and this part of the brain still lights up. So we can ID that part of the brain in anyone who’s preparing to enter our trial and say, okay, that part of the brain we confirm is your hand intention area. And so I’ll make a little cut in the skin, we’ll flap the skin open, just like kind of opening the hood of a car, only a lot smaller, make a perfectly round one inch diameter hole in the skull, remove that bit of skull, open the lining of the brain, the covering of the brain, it’s like a little bag of water that the brain floats in, and then show that part of the brain to our robot. And then this is where the robot shines.

And so I’ll make a little cut in the skin, we’ll flap the skin open, just like kind of opening the hood of a car, only a lot smaller, make a perfectly round one inch diameter hole in the skull, remove that bit of skull, open the lining of the brain, the covering of the brain, it’s like a little bag of water that the brain floats in, and then show that part of the brain to our robot. And then this is where the robot shines.
It can come in and take these tiny, much smaller than human hair, electrodes and precisely insert them into the cortex, into the surface of the brain to a very precise depth, in a very precise spot that avoids all the blood vessels that are coating the surface of the brain. And after the robot’s done with its part, then the human comes back in and puts the implant into that hole in the skull and covers it up, screwing it down to the skull and sewing the skin back together. So the whole thing is a few hours long. It’s extremely low risk compared to the average neurosurgery involving the brain that might, say, open up a deeper part of the brain or manipulate blood vessels in the brain. This opening on the surface of the brain with only cortical micro- insertions carries significantly less risk than a lot of the tumor or aneurysm surgeries that are routinely done.
Lex Fridman
So cortical micro-insertions that are via robot and computer vision are designed to avoid the blood vessels.

So I know you’re a bit biased here, but let’s compare human and machine. So what are human surgeons able to do well and what are robot surgeons able to do well at this stage of our human civilization and development?
So I know you’re a bit biased here, but let’s compare human and machine. So what are human surgeons able to do well and what are robot surgeons able to do well at this stage of our human civilization and development?
Matthew MacDougall
Yeah. Yeah, that’s a good question. Humans are general purpose machines. We’re able to adapt to unusual situations. We’re able to change the plan on the fly. I remember well a surgery that I was doing many years ago down in San Diego where the plan was to open a small hole behind the ear and go reposition a blood vessel that had come to lay on the facial nerve, the trigeminal nerve, the nerve that goes to the face. When that blood vessel lays on the nerve, it can cause just intolerable, horrific shooting pain that people describe like being zapped with a cattle prod. And so the beautiful, elegant surgery is to go move this blood vessel off the nerve. The surgery team, we went in there and started moving this blood vessel and then found that there was a giant aneurysm on that blood vessel that was not easily visible on the pre-op scans. And so the plan had to dynamically change and that the human surgeons had no problem with that, were trained for all those things.

Robots wouldn’t do so well in that situation, at least in their current incarnation, fully robotic surgery, like the electrode insertion portion of the neural link surgery, it goes according to a set plan. And so the humans can interrupt the flow and change the plan, but the robot can’t really change the plan midway through. It operates according to how it was programmed and how it was asked to run. It does its job very precisely, but not with a wide degree of latitude in how to react to changing conditions.
Lex Fridman
So there could be just a very large number of ways that you could be surprised as a surgeon? When you enter a situation, there could be subtle things that you have to dynamically adjust to.

I think we are at the dawn of a new era with AI of the parameters for robot responsiveness to be dramatically broadened, right? I mean, you can’t look at a self-driving car and say that it’s operating under very narrow parameters. If a chicken runs across the road, it wasn’t necessarily programmed to deal with that specifically, but a Waymo or a self-driving Tesla would have no problem reacting to that appropriately. And so surgical robots aren’t there yet, but give it time.

And then there could be a lot of semi-autonomous possibilities of maybe a robotic surgeon could say this situation is perfectly familiar, or this situation is not familiar, and in the not familiar case, a human could take over, but basically be very conservative in saying, okay, this for sure has no issues, no surprises, and let the humans deal with the surprises with the edge cases and all that. That’s one possibility. So you think eventually you’ll be out of the job? Well, you being neurosurgeon, your job being a neurosurgeon. Humans, there will not be many neurosurgeons left on this earth.

It’s so fascinating because if I have a line of work, I would say it’s programming. And if you ask me, for the last, I don’t know, 20 years, what I would recommend for people, I would tell them, yeah, you’ll always have a job if you’re a programmer because there’s more and more computers and all this kind of stuff and it pays well. But then you realize these large language models come along and they’re really damn good at generating code. So overnight you could be surprised like, wow, what is the contribution of the human really? But then you start to think, okay, it does seem that humans have ability, like you said, to deal with novel situations. In the case of programming, it’s the ability to come up with novel ideas to solve problems. It seems like machines aren’t quite yet able to do that. And when the stakes are very high, when it’s life critical as it is in surgery, especially in neurosurgery, then the stakes are very high for a robot to actually replace a human. But it’s fascinating that in this case of Neuralink, there’s a human robot collaboration.

I saw that there’s a lot of practice going on. I mean everything in Neuralink is tested extremely rigorously, but one of the things I saw that there’s a proxy on which the surgeries are performed. So this is both for the robot and for the human, for everybody involved in the entire pipeline. What’s that like, practicing the surgery?

Matthew MacDougall
It’s pretty intense. So there’s no analog to this in human surgery. Human surgery is sort of this artisanal craft that’s handed down directly from master to pupil over the generations. I mean, literally the way you learn to be a surgeon on humans is by doing surgery on humans. I mean, first you watch your professors do a bunch of surgery, and then finally they put the trivial parts of the surgery into your hands, and then the more complex parts, and as your understanding of the point and the purposes of the surgery increases, you get more responsibility in the perfect condition. Doesn’t always go well. In Neuralink’s case, the approach is a bit different. We, of course, practiced as far as we could on animals. We did hundreds of animal surgeries. And when it came time to do the first human, we had just an amazing team of engineers build incredibly lifelike models. One of the engineers, Fran Romano in particular, built a pulsating brain in a custom 3-D printed skull that matches exactly the patient’s anatomy, including their face and scalp characteristics.

And so when I was able to practice that, it’s as close as it really reasonably should get to being the real thing in all the details, including having a mannequin body attached to this custom head. And so when we were doing the practice surgeries, we’d wheel that body into the CT scanner and take a mock CT scan and wheel it back in and conduct all the normal safety checks, verbally, “Stop. This patient we’re confirming his identification is mannequin number…” Blah, blah, blah. And then opening the brain in exactly the right spot using standard operative neuro-navigation equipment, standard surgical drills in the same OR that we do all of our practice surgeries in at Neuralink and having the skull open and have the brain pulse, which adds a degree of difficulty for the robot to perfectly precisely plan and insert those electrodes to the right depth and location. And so we kind of broke new ground on how extensively we practiced for this surgery.
Lex Fridman
So there was a historic moment, a big milestone for Neuralink, in part for humanity, with the first human getting a Neuralink implant in January of this year. Take me through the surgery on Noland. What did it feel like to be part of this?

Matthew MacDougall
Yeah. Well, we are lucky to have just incredible partners at the Barrow Neurologic Institute. They are, I think, the premier neurosurgical hospital in the world. They made everything as easy as possible for the trial to get going and helped us immensely with their expertise on how to arrange the details. It was a much more high pressure surgery in some ways. I mean, even though the outcome wasn’t particularly in question in terms of our participant’s safety, the number of observers, the number of people, there’s conference rooms full of people watching live streams in the hospital rooting for this to go perfectly, and that just adds pressure that is not typical for even the most intense production neurosurgery, say, removing a tumor or placing deep brain stimulation electrodes, and it had never been done on a human before. There were unknown unknowns.

And so definitely a moderate pucker factor there for the whole team not knowing if we were going to encounter, say, a degree of brain movement that was unanticipated or a degree of brain sag that took the brain far away from the skull and made it difficult to insert or some other unknown unknown problem. Fortunately everything went well and that surgery is one of the smoothest outcomes we could have imagined.

You have to do things that haven’t been done before and you have to take risks, calculated risks, you have to do all kinds of safety precautions, but risks nevertheless. I just wish there would be more celebration of that, of the risk taking versus people just waiting on the sidelines waiting for failure and then pointing out the failure. Yeah, it sucks. But in this case, it’s really great that everything went just flawlessly, but it’s unnecessary pressure, I would say.

Yeah, because an MD needs to be in charge of all of the medical decision-making throughout the process, I unscrubbed from the surgery after exposing the brain and presenting it to the robot and placed the targets on the robot software interface that tells the robot where it’s going to insert each thread. That was done with my hand on the mouse, for whatever that’s worth.

Right. The software engineers are amazing on this team, and so they actually provided an interface where you can essentially use a lasso tool and select a prime area of brain real estate, and it will automatically avoid the blood vessels in that region and automatically place a bunch of targets. That allows the human robot operator to select really good areas of brain and make dense applications of targets in those regions, the regions we think are going to have the most high fidelity representations of finger movements and arm movement intentions.

Matthew MacDougall
Yeah. So talking broadly about neurosurgery, we can get anywhere. It’s routine for me to put deep brain stimulating electrodes near the very bottom of the brain, entering from the top and passing about a two millimeter wire all the way into the bottom of the brain. And that’s not revolutionary, a lot of people do that, and we can do that with very high precision. I use a robot from Globus to do that surgery several times a month. It’s pretty routine.

What are your eyes in that situation? What are you seeing? What kind of technology can you use to visualize where you are to light your way?
Matthew MacDougall
Yeah, so it’s a cool process on the software side. You take a preoperative MRI that’s extremely high resolution, data of the entire brain, you put the patient to sleep, put their head in a frame that holds the skull very rigidly, and then you take a CT scan of their head while they’re asleep with that frame on and then merge the MRI and the CT in software. You have a plan based on the MRI where you can see these nuclei deep in the brain. You can’t see them on CT, but if you trust the merging of the two images, then you indirectly know on the CT where that is, and therefore indirectly know where in reference to the titanium frame screwed to their head those targets are. And so this is sixties technology to manually compute trajectories given the entry point and target and dial in some goofy looking titanium manual actuators with little tick marks on them.

And so this is sixties technology to manually compute trajectories given the entry point and target and dial in some goofy looking titanium manual actuators with little tick marks on them.
The modern version of that is to use a robot. Just like a little Kuka arm you might see building cars at the Tesla factory, this small robot arm can show you the trajectory that you intended from the pre-op MRI and establish a very rigid holder through which you can drill a small hole in the skull and pass a small rigid wire deep into that area of the brain that’s hollow, and put your electrode through that hollow wire and then remove all of that except the electrode. So you end up with the electrode very, very precisely placed far from the skull surface. Now, that’s standard technology that’s already been out in the world for a while. Neuralink right now is focused entirely on cortical targets, surface targets because there’s no trivial way to get, say, hundreds of wires deep inside the brain without doing a lot of damage. So your question, what do you see? Well, I see an MRI on a screen. I can’t see everything that DBS electrode is passing through on its way to that deep target.
And so it’s accepted with this approach that there’s going to be about one in a hundred patients who have a bleed somewhere in the brain as a result of passing that wire blindly into the deep part of the brain. That’s not an acceptable safety profile for Neuralink. We start from the position that we want this to be dramatically maybe two or three orders of magnitude safer than that, safe enough, really, that you or I, without a profound medical problem, might on our lunch break someday say, “Yeah, sure, I’ll get that. I’d been meaning to upgrade to the latest version.” And so the safety constraints given that are high, and so we haven’t settled on a final solution for arbitrarily approaching deep targets in the brain.
Lex Fridman
It’s interesting because you have to avoid blood vessels somehow, and you have to… Maybe there’s creative ways of doing the same thing, like mapping out high resolution geometry of blood vessels, and then you can go in blind, but how do you map out that in a way that’s super stable? There’s a lot of interesting challenges there, right?

So this digital telepathy. I didn’t quite understand that you can really map the intention, as you described in the hand knob area, that you can map the intention. Just imagine it. Think about it. That intention can be mapped to actual action in the digital world, and now more and more, so much can be done in the digital world that it can reconnect you to the outside world. It can allow you to have freedom, have independence if you’re a quadriplegic. That’s really powerful. You can go really far with that.

There’s a million ways of people saying the same thing and selling books saying it, but you call it 10,000 hours, you call it spend some chunk of your life, some percentage of your life focusing on this, obsessing about getting better at it. Repetitions, humility, recognizing that you aren’t perfect at any stage along the way, recognizing you’ve got improvements to make in your technique, being open to feedback and coaching from people with a different perspective on how to do it, and then just the constant will to do better. That, fortunately, if you’re not a sociopath, I think your patients bring that with them to the office visits every day. They force you to want to do better all the time.

So every surgery, even if it’s the same exact surgery, is there a lot of variability between that surgery in a different person?
So every surgery, even if it’s the same exact surgery, is there a lot of variability between that surgery in a different person?
Matthew MacDougall
Yeah. A fair bit. A good example for us is the angle of the skull relative to the normal plane of the body axis of the skull over hand knob is pretty wide variation. Some people have really flat skulls and some people have really steeply angled skulls over that area, and that has consequences for how their head can be fixed in sort of the frame that we use and how the robot has to approach the skull. Yeah, people’s bodies are built as differently as the people you see walking down the street, as much variability and body shape and size as you see there. We see in brain anatomy and skull anatomy, there are some people who we’ve had to exclude from our trial for having skulls that are too thick or too thin or scalp that’s too thick or too thin. I think we have the middle 97% or so of people, but you can’t account for all human anatomy variability.

How much mushiness and mess is there? Because taking biology classes, the diagrams are always really clean and crisp. Neuroscience, the pictures of neurons are always really nice and [inaudible 04:32:44], but whenever I look at pictures of real brains, they’re all… I don’t know what is going on. So how much our biological systems in reality, how hard is it to figure out what’s going on?

Matthew MacDougall
Not too bad. Once you really get used to this, that’s where experience and skill and education really come into play is if you stare at a thousand brains, it becomes easier to kind of mentally peel back the, say, for instance, blood vessels that are obscuring the sulci and gyri, know kind of the wrinkle pattern of the surface of the brain. Occasionally when you’re first starting to do this and you open the skull, it doesn’t match what you thought you were going to see based on the MRI. And with more experience, you learn to kind of peel back that layer of blood vessels and see the underlying pattern of wrinkles in the brain and use that as a landmark for where you are.

Yeah. So I was describing hand knob earlier. That’s a pattern of the wrinkles in the brain. It’s sort of this Greek letter, omega shaped area of the brain.

So you have this strip of brain running down the top called the primary motor area, and I’m sure you’ve seen this picture of the homunculus laid over the surface of the brain, the weird little guy with huge lips and giant hands. That guy sort of lays with his legs up at the top of the brain and face arm areas farther down, and then some kind of mouth, lip, tongue areas farther down. And so the hand is right in there, and then the areas that control speech, at least on the left side of the brain in most people are just below that. And so any muscle that you voluntarily move in your body, the vast majority of that references that strip or those intentions come from that strip of brain, and the wrinkle for hand knob is right in the middle of that.

Matthew MacDougall
Yep.

Also close to the surface.

Matthew MacDougall
Vision’s a little deeper. And so this gets to your question about how deep can you get. To do vision, we can’t just do the surface of the brain. We have to be able to go in, not as deep as we’d have to go for DBS, but maybe a centimeter deeper than we’re used to for hand insertions. And so that’s work in progress. That’s a new set of challenges to overcome.

Matthew MacDougall
Yeah. The nails.

It’s because it’s rigid and then if you look at the threads, they’re flexible. What can you say that’s interesting to you about that kind of approach of the flexible threads to deliver the electrodes next to the neurons?
It’s because it’s rigid and then if you look at the threads, they’re flexible. What can you say that’s interesting to you about that kind of approach of the flexible threads to deliver the electrodes next to the neurons?
Matthew MacDougall
Yeah. I mean, the goal there comes from experience. I mean, we stand on the shoulders of people that made Utah Arrays and used Utah Arrays for decades before we ever even came along. Neuralink arose, partly this approach to technology arose out of a need recognized after Utah Arrays would fail routinely because the rigid electrodes, those spikes that are literally hammered using an air hammer into the brain, those spikes generate a bad immune response that encapsulates the electrode spikes in scar tissue essentially. And so one of the projects that was being worked on in the Anderson Lab at Caltech when I got there was to see if you could use chemotherapy to prevent the formation of scars. Things are pretty bad when you’re jamming a bed of nails into the brain, and then treating that with chemotherapy to try to prevent scar tissue, it’s like, maybe we’ve gotten off track here, guys. Maybe there’s a fundamental redesign necessary.

And so Neuralink’s approach of using highly flexible, tiny electrodes avoids a lot of the bleeding, avoids a lot of the immune response that ends up happening when rigid electrodes are pounded into the brain. And so what we see is our electrode longevity and functionality and the health of the brain tissue immediately surrounding the electrode is excellent. I mean, it goes on for years now in our animal models.

I think the most interesting maybe underappreciated fact is that it really does control almost everything. I don’t know, for an out of the blue example, imagine you want a lever on fertility. You want to be able to turn fertility on and off. There are legitimate targets in the brain itself to modulate fertility, say blood pressure. You want to modulate blood pressure, there are legitimate targets in the brain for doing that. Things that aren’t immediately obvious as brain problems are potentially solvable in the brain. And so I think it’s an under-explored area for primary treatments of all the things that bother people.

The use case of the mouse is after researching all this and part of it’s just watching Nolan have so much fun. If you can get that bits per second look really high with the mouse, being able to interact, because if you think about the way on the smartphone, the way you swipe, that was transformational. How we interact with the thing, it’s subtle, you don’t realize it, but to be able to touch a phone and to scroll with your finger, that changed everything. People were sure you need a keyboard to type. There’s a lot of HCI aspects to that that changed how we interact with computers, so there could be a certain rate of speed with the mouse that would change everything. You might be able to just click around a screen extremely fast. I can’t see myself getting a Neuralink for much more rapid interaction with the digital devices.

Yeah, I think recording speech intentions from the brain might change things as well, the value proposition for the average person. A keyboard is a pretty clunky human interface, requires a lot of training. It’s highly variable in the maximum performance that the average person can achieve. I think taking that out of the equation and just having a natural word to computer interface might change things for a lot of people.

That starts to sound sort of like embedded super intelligence. If you can silently ask for the Wikipedia article on any subject and have it read to you without any observable change happening in the outside world. For one thing, standardized testing is obsolete.

If it’s done well in the UX side, it could change, I don’t know if it transforms society, but it really can create a kind of shift in the way we interact with digital devices in the way that a smartphone did. Just having to look into the safety of everything involved, I would totally try it. So it doesn’t have to go to some incredible thing where you have, it connects your vision or to some other, it connects all over your brain. That could be just connecting to the hand knob. You might have a lot of interesting interaction, human computer interaction possibilities. That’s really interesting.

Your brain will first of all adjust and you develop, like any other skill, like touch typing. You develop in that same kind of way.

So from all the surgeries you’ve done, from everything you understand the brain, how much does neuroplasticity come into play? How adaptable is the brain? For example, just even in the case of healing from surgery or adapting to the post-surgery situation.

Matthew MacDougall
The answer that is sad for me and other people of my demographic is that plasticity decreases with age. Healing decreases with age. I have too much gray hair to be optimistic about that. There are theoretical ways to increase plasticity using electrical stimulation. Nothing that is totally proven out as a robust enough mechanism to offer widely to people.

There are theoretical ways to increase plasticity using electrical stimulation. Nothing that is totally proven out as a robust enough mechanism to offer widely to people.
But yeah, I think there’s cause for optimism that we might find something useful in terms of say, an implanted electrode that improves learning. Certainly there’s been some really amazing work recently from Nicholas Schiff, Jonathan Baker and others who have a cohort of patients with moderate traumatic brain injury who have had electrodes placed in the deep nucleus in the brain called the central median nucleus or just near central median nucleus, and when they apply small amounts of electricity to that part of the brain, it’s almost like electronic caffeine.
They’re able to improve people’s attention and focus. They’re able to improve how well people can perform a task. I think in one case, someone who was unable to work, after the device was turned on, they were able to get a job. And that’s sort of one of the holy grails for me with Neuralink and other technologies like this is from a purely utilitarian standpoint, can we make people able to take care of themselves and their families economically again? Can we make it so someone who’s fully dependent and even maybe requires a lot of caregiver resources, can we put them in a position to be fully independent, taking care of themselves, giving back to their communities? I think that’s a very compelling proposition and what motivates a lot of what I do and what a lot of the people at Neuralink are working for.
Lex Fridman
It’s just a cool possibility that if you put a Neuralink in there, that the brain adapts the other part of the brain adapts too and integrates it. The capacity of the brain to do that is really interesting. Probably unknown to the degree to which you can do that, but you’re now connecting an external thing to it, especially once it’s doing stimulation. The biological brain and the electronic brain outside of it working together, the possibilities there are really interesting. It’s still unknown, but interesting. It feels like the brain is really good at adapting to whatever, but of course it is a system that by itself is already, everything serves a purpose and so you don’t want to mess with it too much.

Matthew MacDougall
I think it’s a certain kind of brittleness or a failure on the company’s side if we need me to do all the surgeries. I think something that I would very much like to work towards is a process that is so simple and so robust on the surgery side that literally anyone could do it. We want to get away from requiring intense expertise or intense experience to have this done and make it as simple and translatable as possible. I mean, I would love it if every neurosurgeon on the planet had no problem doing this. I think we’re probably far from a regulatory environment that would allow people that aren’t neurosurgeons to do this, but not impossible.

All right, I’ll sign up for that. Did you ever anthropomorphize the robot R1? Do you give it a name? Do you see it as a friend as working together with you?

Matthew MacDougall
It’s funny when in the middle of the surgery, there’s a part of it where I stand basically shoulder to shoulder with the robot, and so if you’re in the room reading the body language, it’s my brother in arms there. We’re working together on the same problem. Yeah, I’m not threatened by it.

Life and death
Lex Fridman
Keep telling yourself that. How have all the surgeries that you’ve done over the years, the people you’ve helped and the stakes, the high stakes that you’ve mentioned, how has that changed your understanding of life and death?
Keep telling yourself that. How have all the surgeries that you’ve done over the years, the people you’ve helped and the stakes, the high stakes that you’ve mentioned, how has that changed your understanding of life and death?
Matthew MacDougall
Yeah, it gives you a very visceral sense, and this may sound trite, but it gives you a very visceral sense that death is inevitable. On one hand, as a neurosurgeon, you’re deeply involved in these, just hard to fathom tragedies, young parents dying, leaving a four-year-old behind, say. And on the other hand, it takes the sting out of it a bit because you see how just mind-numbingly universal death is. There’s zero chance that I’m going to avoid it. I know techno-optimists right now and longevity buffs right now would disagree on that 0.000% estimate, but I don’t see any chance that our generation is going to avoid it. Entropy is a powerful force and we are very ornate, delicate, brittle, DNA machines that aren’t up to the cosmic ray bombardment that we’re subjected to.

Entropy is a powerful force and we are very ornate, delicate, brittle, DNA machines that aren’t up to the cosmic ray bombardment that we’re subjected to.
So on the one hand, every human that has ever lived died or will die. On the other hand, it’s just one of the hardest things to imagine inflicting on anyone that you love is having them gone. I mean, I’m sure you’ve had friends that aren’t living anymore and it’s hard to even think about them. And so I wish I had arrived at the point of nirvana where death doesn’t have a sting, I’m not worried about it. But I can at least say that I’m comfortable with the certainty of it, if not having found out how to take the tragedy out of it. When I think about my kids either not having me or me not having them or my wife.
Lex Fridman
Maybe I’ve come to accept the intellectual certainty of it, but it may be the pain that comes with losing the people you love. But I don’t think I’ve come to understand the existential aspect of it, that this is going to end, and I don’t mean in some trite way. I mean, it certainly feels like it’s not going to end. You live life like it’s not going to end. And the fact that this light that’s shining, this consciousness is going to no longer be in one moment, maybe today. It fills me when I really am able to load all that in with Ernest Becker’s terror. It is a real fear.

It fills me when I really am able to load all that in with Ernest Becker’s terror. It is a real fear.
I think people aren’t always honest with how terrifying it is. I think the more you are able to really think through it, the more terrifying it is. It’s not such a simple thing, “Oh, well, it’s the way life is.” If you really can load that in, it’s hard, but I think that’s why the Stoics did it, because it helps you get your shit together and be like, “The moment, every single moment you’re alive is just beautiful” and it’s terrifying that it’s going to end, and it’s almost like you’re shivering in the cold, a child helpless. This kind of feeling,
And then it makes you, when you have warmth, when you have the safety, when you have the love to really appreciate it. I feel like sometimes in your position when you mentioned armor just to see death, it might make you not be able to see that, the finiteness of life because if you kept looking at that, it might break you. So it is good to know that you’re kind of still struggling with that. There’s the neurosurgeon and then there’s a human, and the human is still able to struggle with that and feel the fear of that and the pain of that.
Matthew MacDougall
Yeah, it definitely makes you ask the question of how many of these can you see and not say, “I can’t do this anymore”? But I mean you said it well, I think it gives you an opportunity to just appreciate that you’re alive today and I’ve got three kids and an amazing wife, and I am really happy. Things are good. I get to help on a project that I think matters. I think it moves us forward. I’m a very lucky person.

It’s the early steps of a potentially gigantic leap for humanity. It’s a really interesting one. And it’s cool because you read about all this stuff in history where it’s like the early days. I’ve been reading, before going to the Amazon, I would read about explorers that would go and explore even the Amazon jungle for the first time. It’s just those are the early steps or early steps into space, early steps in any discipline in physics and mathematics, and it’s cool because on the grand scale, these are the early steps into delving deep into the human brain, so not just observing the brain but be able to interact with the human brain. It’s going to help a lot of people, but it also might help us understand what the hell’s going on in there.

Matthew MacDougall
Yeah. I think ultimately we want to give people more levers that they can pull. You want to give people options. If you can give someone a dial that they can turn on how happy they are, I think that makes people really uncomfortable. But now talk about major depressive disorder. Talk about people that are committing suicide at an alarming rate in this country, and try to justify that queasiness in that light of, you can give people a knob to take away suicidal ideation, suicidal intention. I would give them that knob. I don’t know how you justify not doing that.

You can think about all the suffering that’s going on in the world, every single human being that’s suffering right now. It’ll be a glowing red dot. The more suffering, the more it’s glowing, and you just see the map of human suffering and any technology that allows you to dim that light of suffering on a grand scale is pretty exciting. Because there’s a lot of people suffering and most of them suffer quietly, and we look away too often, and we should remember those are suffering because once again, most of them are suffering quietly.

Matthew MacDougall
Well, and on a grander scale, the fabric of society. People have a lot of complaints about how our social fabric is working or not working, how our politics is working or not working. Those things are made of neurochemistry too in aggregate, right? Our politics is composed of individuals with human brains, and the way it works or doesn’t work is potentially tunable in the sense that, I don’t know, say remove our addictive behaviors or tune our addictive behaviors for social media or our addiction to outrage, our addiction to sharing the most angry political tweet we can find. I don’t think that leads to a functional society, and if you had options for people to moderate that maladaptive behavior, there could be huge benefits to society. Maybe we could all work together a little more harmoniously toward useful ends.

There’s a sweet spot, like you mentioned. You don’t want to completely remove all the dark sides of human nature. Those are somehow necessary to make the whole thing work, but there’s a sweet spot.

Consciousness
Lex Fridman
Yeah. When you, all the surgeries you’ve done, have you seen consciousness in there ever? Was there a glowing light?
Yeah. When you, all the surgeries you’ve done, have you seen consciousness in there ever? Was there a glowing light?
Matthew MacDougall
I have this sense that I never found it, never removed it like a Dementor in Harry Potter. I have this sense that consciousness is a lot less magical than our instincts want to claim it is. It seems to me like a useful analog for about what consciousness is in the brain is that we have a really good intuitive understanding of what it means to say, touch your skin and know what’s being touched. And I think consciousness is just that level of sensory mapping applied to the thought processes in the brain itself.

So what I’m saying is, consciousness is the sensation of some part of your brain being active, so you feel it working. You feel the part of your brain that thinks of red things or winged creatures or the taste of coffee. You feel those parts of your brain being active, the way that I’m feeling my palm being touched, and that sensory system that feels the brain working is consciousness.
Lex Fridman
That’s so brilliant. It’s the same way. It’s the sensation of touch when you’re touching a thing. Consciousness is the sensation of you feeling your brain working, your brain thinking, your brain perceiving.

Matthew MacDougall
Which isn’t like a warping of space-time or some quantum field effect, right? It’s nothing magical. People always want to ascribe to consciousness something truly different, and there’s this awesome long history of people looking at whatever the latest discovery in physics is to explain consciousness because it’s the most magical, the most out there thing that you can think of, and people always want to do that with consciousness. I don’t think that’s necessary. It’s just a very useful and gratifying way of feeling your brain work.

Thanks for listening to this conversation with Matthew MacDougall. Now, dear friends, here’s Bliss Chapman, brain interface software lead at Neuralink. You told me that you’ve met hundreds of people with spinal cord injuries or with ALS, and that your motivation for helping at Neuralink is grounded in wanting to help them. Can you describe this motivation?

Can you describe this motivation?
Bliss Chapman
Yeah. First, just a thank you to all the people I’ve gotten a chance to speak with for sharing their stories with me. I don’t think there’s any world really in which I can share their stories as powerful way as they can, but just I think to summarize at a very high level, what I hear over and over again is that people with ALS or severe spinal cord injury in a place where they basically can’t move physically anymore, really at the end of the day are looking for independence. And that can mean different things for different people.

And that can mean different things for different people.
For some folks, it can mean the ability just to be able to communicate again independently without needing to wear something on their face, without needing a caretaker to be able to put something in their mouth. For some folks, it can mean independence to be able to work again, to be able to navigate a computer digitally, efficiently enough to be able to get a job, to be able to support themselves, to be able to move out and ultimately be able to support themselves after their family maybe isn’t there anymore to take care of them.
And for some folks, it’s as simple as just being able to respond to their kid in time before they run away or get interested in something else. And these are deeply personal and very human problems. And what strikes me again and again when talking with these folks is that this is actually an engineering problem. This is a problem that with the right resources, with the right team, can make a lot of progress on. And at the end of the day, I think that’s a deeply inspiring message and something that makes me excited to get up every day.
Lex Fridman
So it’s both an engineering problem in terms of a BCI, for example, that can give them capabilities where they can interact with the world, but also on the other side, it’s an engineering problem for the rest of the world to make it more accessible for people living with quadriplegia?

Bliss Chapman
Yeah. And actually, I’ll take a broad view lens on this for a second. I think I’m very in favor of anyone working in this problem space. So beyond BCI, I’m happy and excited and willing to support any way I can, folks working on eye tracking systems, working on speech to text systems, working on head trackers or mouse sticks or quad sticks. And I’ve met many engineers and folks in the community that do exactly those things.

And I’ve met many engineers and folks in the community that do exactly those things.
And I think for the people we’re trying to help, it doesn’t matter what the complexity of the solution is as long as the problem is solved. And I want to emphasize that there can be many solutions out there that can help with these problems. And BCI is one of a collection of such solutions. So BCI in particular, I think offers several advantages here. And I think the folks that recognize this immediately are usually the people who have spinal cord injury or some form of paralysis.
Usually you don’t have to explain to them why this might be something that could be helpful. It’s usually pretty self-evident, but for the rest of us folks that don’t live with severe spinal cord injury or who don’t know somebody with ALS, it’s not often obvious why you would want a brain implant to be able to connect and navigate a computer.
And it’s surprisingly nuanced, and to the degree that I’ve learned a huge amount just working with Noland in the first Neuralink clinical trial and understanding from him and his words why this device is impactful for him, and it’s a nuanced topic. It can be the case that even if you can achieve the same thing, for example, with a mouse stick when navigating a computer, he doesn’t have access to that mouse stick every single minute of the day. He only has access when someone is available to put it in front of him. And so a BCI can really offer a level of independence and autonomy that, if it wasn’t literally physically part of your body, it’d be hard to achieve in any other way.
Lex Fridman
So there’s a lot of fascinating aspects to what it takes to get Noland to be able to control a cursor on the screen with his mind. You texted me something that I just love. You said, “I was part of the team that interviewed and selected P1, I was in the operating room during the first human surgery monitoring live signals coming out of the brain. I work with the user basically every day to develop new UX paradigms, decoding strategies, and I was part of the team that figured out how to recover useful BCI to new world record levels when the signal quality degraded.” We’ll talk about, I think every aspect of that, but just zooming out, what was it like to be a part of that team and part of that historic, I would say, historic first?

Bliss Chapman
Yeah. I think for me, this is something I’ve been excited about for close to 10 years now. And so to be able to be even just some small part of making it a reality is extremely exciting. A couple maybe special moments during that whole process that I’ll never really truly forget. One of them is entering the actual surgery. At that point in time, I know Noland quite well. I know his family. And so I think the initial reaction when Noland is rolled into the operating room is just an “Oh, shit” kind of reaction. But at that point, muscle memory kicks in and you sort of go into, you let your body just do all the talking.

But at that point, muscle memory kicks in and you sort of go into, you let your body just do all the talking.
And I have the lucky job in that particular procedure to just be in charge of monitoring the implant. So my job is to sit there, to look at the signals coming off the implant, to look at the live brain data streaming off the device as threads are being inserted into the brain and just to basically observe and make sure that nothing is going wrong or that there’s no red flags or fault conditions that we need to go and investigate or pause the surgery to debug.
And because I had that sort of spectator view of the surgery, I had a slightly removed perspective than I think most folks in the room. I got to sit there and think to myself, “Wow, that brain is moving a lot.” When you look inside the craniectomy that we stick the threads in, one thing that most people don’t realize is the brain moves. The brain moves a lot when you breathe, your heart beats, and you can see it visibly. So that’s something that I think was a surprise to me and very, very exciting to be able to see someone’s brain who you physically know and have talked with that length, actually pausing and moving inside their skull.
Lex Fridman
And they used that brain to talk to you previously, and now it’s right there moving.
And they used that brain to talk to you previously, and now it’s right there moving.
Bliss Chapman
Yep.
Yep.
Lex Fridman
Actually, I didn’t realize that in terms of the thread sending, so the Neuralink implant is active during surgery and one thread at a time, you’re able to start seeing the signal?

So that’s part of the way you test that the thing is working?
So that’s part of the way you test that the thing is working?
Bliss Chapman
Yeah. So actually in the operating room, right after we sort of finished all the thread insertions, I started collecting what’s called broadband data. So broadband is basically the most raw form of signal you can collect from a Neuralink electrode. It’s essentially a measurement of the local fuel potential or the voltage essentially measured by that electrode. And we have a certain mode in our application that allows us to visualize where detected spikes are. So it visualizes where in the broadband signal and it’s very, very raw form of the data, a neuron is actually spiking. And so one of these moments that I’ll never forget as part of this whole clinical trial is seeing live in the operating room while he’s still under anesthesia, beautiful spikes being shown in the application, just streaming live to a device I’m holding in my hand.

During that procedure, there was actually a lot of cameramen in the room, so they also were curious and wanted to see, there’s several neurosurgeons in the room who were all just excited to see robots taking their job, and they were all crowded around a small little iPhone watching this live brain data stream out of his brain.

What was that like seeing the robot do some of the surgery? So the computer vision aspect where it detects all the spots that avoid the blood vessels, and then obviously with the human supervision, then actually doing the really high precision connection of the threads to the brain?

So what about when Noland woke up? Do you remember a moment where he was able to move the cursor, not move the cursor, but get signal from the brain such that it was able to show that there’s a connection?

Yeah. Yeah. So we are quite excited to move as quickly as we can, and Noland was really, really excited to get started. He wanted to get started, actually the day of surgery, but we waited until the next morning very patiently. It’s a long night.

Bliss Chapman
… we waited until the next morning very patiently. So a long night. And the next morning in the ICU where he was recovering, he wanted to get started and actually start to understand what kind of signal we can measure from his brain. And maybe for folks who are not familiar with the Neuralink system, we implant the Neuralink system or the Neuralink implant in the motor cortex. So the motor cortex is responsible for representing things like motor intent. If you imagine closing and opening your hand, that kind of signal representation would be present in the motor cortex.

So the motor cortex is responsible for representing things like motor intent. If you imagine closing and opening your hand, that kind of signal representation would be present in the motor cortex.
If you imagine moving your arm back and forth or wiggling a pinky, this sort of signal can be present in the motor cortex. So one of the ways we start to map out what kind of signal do we actually have access to, in any particular individual’s brain, is through this task called body mapping. And body mapping is where you essentially present a visual to the user and you say, “Hey, imagine doing this,” and their visual is a 3D hand opening, closing or index finger modulating up and down.
And you ask the user to imagine that, and obviously you can’t see them do this, because they’re paralyzed, so you can’t see them actually move their arm. But while they do this task, you can record neural activity and you can basically offline model and check, “Can I predict, or can I detect the modulation corresponding with those different actions?” And so we did that task and we realized, “Hey, there’s actually some modulation associated with some of his hand motion,” which was a first indication that, “okay, we can potentially use that modulation to do useful things in the world.” For example, control a computer cursor.
And he started playing with it, the first time we showed him it. And we actually just took the same live view of his brain activity and put it in front of him and we said, “Hey, you tell us what’s going on? We’re not you. You’re able to imagine different things, and we know that it’s modulating some of these neurons, so you figure out for us, what that is actually representing.” And so he played with it for a bit. He was like, “I don’t quite get it yet.” He played for a bit longer and he said, “Oh, when I move this finger, I see this particular neuron start to fire more.”
And I said, “Okay, prove it. Do it again.” And so he said, “Okay, three, two, one,” boom. And the minute he moved, you can see instantaneously this neuron is firing, single neuron. I can tell you the exact channel number if you’re interested. It’s stuck in my brain now forever. But that single channel firing was a beautiful indication that it was behaved really modulated, neural activity, that could then be used for downstreaming tasks, like decoding a computer cursor.
Lex Fridman
And when you say single channel, is that associated with a single electrode?
And when you say single channel, is that associated with a single electrode?

That’s incredible that, that works. When I was learning about all this and loading it in, it was just blowing my mind that the intention, you can visualize yourself moving the finger. That can turn into a signal, and the fact that you can then skip that step and visualize the cursor moving, or have the intention of the cursor moving. And that leading to a signal that can then be used to move the cursor? There is so many exciting things there to learn about the brain, about the way the brain works, the very fact of there existing signal that can be used, is really powerful.

But it feels like that’s just the beginning of figuring out how that signal could be used really, really effectively? I should also just, there’s so many fascinating details here, but you mentioned the body mapping step. At least in the version I saw, that Noland was showing off, there’s a super nice interface, a graphical interface, but it just felt like I was in the future.

Yeah. And I think the UX design component here is underrated for BCI development in general. There’s a whole interaction effect between the ways in which you visualize an instruction to the user, and the kinds of signal you can get back. And that quality of your behavioral alignment to the neural signal, is a function of how good you are at expressing to the user what you want them to do. And so yeah, we spend a lot of time thinking about the UX, of how we build our applications, of how the decoder actually functions, the control surfaces it provides to the user. All these little details matter a lot.

Bliss Chapman
So maybe before diving into what we do, it’s worth understanding what we’re trying to measure, because that dictates a lot of the requirements for the system that we build. And what we’re trying to measure is really individual neurons, producing action potentials. And action potential is, you can think of it like a little electrical impulse that you can detect, if you’re close enough. And by being close enough, I mean within let’s say 100 microns of that cell. And 100 microns is a very, very tiny distance. And so the number of neurons that you’re going to pick up with any given electrode, is just a small radius around that electrode.

And 100 microns is a very, very tiny distance. And so the number of neurons that you’re going to pick up with any given electrode, is just a small radius around that electrode.
And the other thing worth understanding about the underlying biology here, is that when neurons produce an action potential, the width of that action potential is about one millisecond. So from the start of the spike, to the end of the spike, that whole width of that characteristic feature, of a neuron firing, is one millisecond wide. And if you want to detect that an individual spike is occurring or not, you need to sample that signal, or sample the local fuel potential nearby that a neuron… Much more frequently than once a millisecond. You need to sample many, many times per millisecond, to be able to detect that this is actually the characteristic waveform of a neuron producing an action potential.
And so we sample across all 1,024 electrodes, about 20,000 times a second. 20,000 times a second means for any given one millisecond window, we have about 20 samples that tell us what that exact shape of that actual potential looks like. And once we’ve sort of sampled at super high rate the underlying electrical field nearby these cells, we can process that signal into just where do we detect a spike, or where do we not? Sort of a binary signal, one or zero. Do we detect a spike in this one millisecond or not?
And we do that because the actual information carrying subspace of neural activity, is just when our spikes occurring. Essentially everything that we care about for decoding can be captured or represented in the frequency characteristics of spike trains. Meaning, how often are spikes firing in any given window of time. And so that allows us to do sort of a crazy amount of compression, from this very rich high-density signal, to something that’s much, much more sparse and compressible, that can be sent out over a wireless radio. Like a Bluetooth communication for example.
Lex Fridman
Quick tangents here. You mentioned electrode neuron, there’s a local neighborhood of neurons nearby. How difficult is it to isolate from where the spike came from?

Bliss Chapman
So there’s a whole field of academic neuroscience work on exactly this problem, of basically given a single electrode, or given a set of electrodes measuring a set of neurons. How can you sort, spike sort, which spikes are coming from what neuron? And this is a problem that’s pursued in academic work, because you care about it for understanding what’s going on in the underlying neuroscience of the brain. If you care about understanding how the brain’s representing information, how that’s evolving through time, then that’s a very, very important question to understand.

If you care about understanding how the brain’s representing information, how that’s evolving through time, then that’s a very, very important question to understand.
For the engineering side of things, at least at the current scale, if the number of neurons per electrode is relatively small, you can get away with basically ignoring that problem completely. You can think of it like a random projection of neurons to electrodes, and there may be in some cases more than one neuron per electrode. But if that number is small enough, those signals can be thought of as sort of a union of the two.
And for many applications, that’s a totally reasonable trade-off to make, and can simplify the problem a lot. And as you sort of scale out channel count, the relevance of distinguishing individual neurons becomes less important. Because you have more overall signal, and you can start to rely on correlations or covariate structure in the data to help understand when that channel is firing… What does that actually represent? Because you know that when that channel’s firing in concert with these other 50 channels, that means move left. But when that same channel’s firing with concert with these other 10 channels, that means move right.
Lex Fridman
Okay. So you have to do this kind of spike detection onboard, and you have to do that super efficiently? So fast, and not use too much power, because you don’t want to be generating too much heat, so it’d have to be a super simple signal processing step?

Is there some wisdom you can share about what it takes to overcome that challenge?
Is there some wisdom you can share about what it takes to overcome that challenge?
Bliss Chapman
Yeah. So we’ve tried many different versions of basically turning this raw signal into a feature that you might want to send off the device. And I’ll say that I don’t think we’re at the final step of this process, this is a long journey. We have something that works clearly today, but there can be many approaches that we find in the future that are much better than what we do right now. So some versions of what we do right now, and there’s a lot of academic heritage to these ideas, so I don’t want to claim that these are original Neuralink ideas or anything like that.

So some versions of what we do right now, and there’s a lot of academic heritage to these ideas, so I don’t want to claim that these are original Neuralink ideas or anything like that.
But one of these ideas is basically to build sort of like a convolutional filter almost, if you will. That slides across the signal and looks for a certain template to be matched. That template consists of how deep the spike modulates, how much it recovers, and what the duration and window of time is for that, the whole process takes. And if you can see in the signal that, that template is matched within certain bounds, then you can say, “Okay, that’s a spike.” One reason that approach is super convenient, is that you can actually implement that extremely efficiently in hardware. Which means that you can run it in low power across 1,024 channels all at once.
Another approach that we’ve recently started exploring, and this can be combined with the spike detection approach, is something called spike band power. And the benefits of that approach are that you may be able to pick up some signal from neurons that are maybe too far away to be detected as a spike, because the farther away you are from an electrode, the weaker that actual spike waveform will look like on that electrode. So you might be able to pick up population level activity of things that are maybe slightly outside the normal recording radius… What neuroscientists sometimes refer to as the hash of activity, the other stuff that’s going on. And you can look at across many channels how that background noise is behaving, and you might be able to get more juice out of the signal that way.
But it comes at a cost. That signal is now a floating point representation, which means it’s more expensive to send out over a power. It means you have to find different ways to compress it, that are different than what you can apply to binary signals. So there’s a lot of different challenges associated with these different modalities.
Lex Fridman
So also in terms of communication, you’re limited by the amount of data you can send?

Yeah. This is a passion project of mine. So I want to build the best mouse in the world. I don’t want to build the Chevrolet Spark or whatever of electric cars. I want to build the Tesla Roadster version of a mouse. And I really do think it’s quite possible that within five to 10 years that most eSports competitions are dominated by people with paralysis.

This is a very real possibility for a number of reasons. One is that they’ll have access to the best technology to play video games effectively. The second is they have the time to do so. So those two factors together are particularly potent for eSport competitors.

Which, it is another way to interact with a digital device, and there’s something to that, if it’s a fundamentally different experience, more efficient experience? Even if it’s not like some kind of full-on high bandwidth communication, if it’s just the ability to move the mouse 10X faster, like the bits per second? If I can achieve a bits per second at 10X what I can do with a mouse, that’s a really interesting possibility of what that can do? Especially as you get really good at it. With training.

It’s definitely the case that you have a higher ceiling performance, because you don’t have to buffer your intention through your arm, through your muscle. You get just by nature of having a brain implant at all, like 75 millisecond lead time on any action that you’re actually trying to take. And there’s some nuance to this, there’s evidence that the motor cortex, you can sort of plan out sequences of actions, so you may not get that whole benefit all the time. But for reaction time style games, where you just want to… Somebody’s over here, snipe them, that kind of thing? You actually do have just an inherent advantage, because you don’t need to go through muscle.

But for reaction time style games, where you just want to… Somebody’s over here, snipe them, that kind of thing? You actually do have just an inherent advantage, because you don’t need to go through muscle.
So the question is, just how much faster can you make it? And we’re already faster than what you would do if you’re going through muscle from a latency point of view, and we’re in the early stages of that. I think we can push it. So our end to end latency right now from brain spike to cursor movement, it’s about 22 milliseconds. If you think about the best mice in the world, the best gaming mice, that’s about five milliseconds ish of latency, depending on how you measure, depending how fast your screen refreshes, there’s a lot of characteristics that matter there. And the rough time for a neuron in the brain to actually impact your command of your hand is about 75 milliseconds.
So if you look at those numbers, you can see that we’re already competitive and slightly faster than what you’d get by actually moving your hand. And this is something that if you ask Noland about it, when he moved the cursor for the first time… We asked him about this, it was something I was super curious about. “What does it feel like when you’re modulating a click intention, or when you’re trying to just move the cursor to the right?” He said it moves before he is actually intending it to. Which is kind of a surreal thing, and something that I would love to experience myself one day, what is that like to have the thing just be so immediate, so fluid, that it feels like it’s happening before you’re actually intending it to move?
Lex Fridman
Yeah. I suppose we’ve gotten used to that latency, that natural latency that happens. So is currently the bottleneck, the communication? So the Bluetooth communication? What’s the actual bottleneck? I mean there’s always going to be a bottleneck, what’s the current bottleneck?
Yeah. I suppose we’ve gotten used to that latency, that natural latency that happens. So is currently the bottleneck, the communication? So the Bluetooth communication? What’s the actual bottleneck? I mean there’s always going to be a bottleneck, what’s the current bottleneck?
Bliss Chapman
Yeah. A couple things. So kind of hilariously, Bluetooth low- energy protocol has some restrictions on how fast you can communicate. So the protocol itself establishes a standard of the most frequent sort of updates you can send, are on the order of 7.5 milliseconds. And as we push latency down to the level of individual spikes impacting control, that level of resolution, that kind of protocol is going to become a limiting factor at some scale.

And as we push latency down to the level of individual spikes impacting control, that level of resolution, that kind of protocol is going to become a limiting factor at some scale.
Another sort of important nuance to this, is that it’s not just the Neuralink itself that’s part of this equation. If you start pushing latency below the level of how fast you’re going to refresh, then you have another problem. You need your whole system to be able to be as reactive as the limits of what the technology can offer.
Lex Fridman
Yes.
Yes.

120 hertz just doesn’t work anymore, if you’re trying to have something respond at something that’s at the level of one millisecond.

That’s a really cool challenge. I also like that for a T-shirt, the best mouse in the world. Tell me on the receiving end, so the decoding step? Now we figured out what the spikes are, we’ve got them all together, now we’re sending that over to the app. What’s the decoding step look like?

So maybe working backwards from the goal. The goal is to help someone with paralysis. In this case, Noland. Be able to navigate his computer independently. And we think the best way to do that, is to offer them the same tools that we have to navigate our software. Because we don’t want to have to rebuild an entire software ecosystem for the brain, at least not yet. Maybe someday you can imagine there’s UXs that are built natively for BCI, but in terms of what’s useful for people today, I think most people would prefer to be able to just control mouse and keyboard inputs, to all the applications that they want to use for their daily jobs, for communicating with their friends, et cetera.

And so the job of the application is really to translate this wireless stream of brain data, coming off the implant, into control of the computer. And we do that by essentially building a mapping from brain activity to sort of the HID inputs, to the actual hardware. So HID is just the protocol for communicating like input device events, so for example, move mouse to this position or press this key down. And so that mapping is fundamentally what the app is responsible for. But there’s a lot of nuance of how that mapping works, and we spent a lot of time to try to get it right, and we’re still in the early stages of a long journey to figure out how to do that optimally.
So one part of that process is decoding. So decoding is this process of taking the statistical patterns of brain data, that’s being channeled across this Bluetooth connection to the application. And turning it into, for example, a mouse movement. And that decoding step, you can think of it in a couple of different parts. So similar to any machine learning problem, there’s a training step, and there’s an [inaudible 05:32:39] step. The training step in our case is a very intricate behavioral process where the user has to imagine doing different actions. So for example, they’ll be presented a screen with a cursor on it, and they’ll be asked to push that cursor to the right. Then imagine pushing that cursor to the left, push it up, push it down. And we can basically build up a pattern or using any sort of modern ML method of mapping of given this brain data, and then imagine behavior, map one to the other.
And then at test time you take that same pattern matching system. In our case it’s a deep neural network, and you run it and you take the live stream of brain data coming off their implant, you decode it by pattern matching to what you saw at calibration time, and you use that for a control of the computer. Now a couple sort of rabbit holes that I think are quite interesting. One of them has to do with how you build that best template matching system. Because there’s a variety of behavioral challenges and also debugging challenges when you’re working with someone who’s paralyzed.
Because again, fundamentally you don’t observe what they’re trying to do, you can’t see them attempt to move their hand. And so you have to figure out a way to instruct the user to do something, and validate that they’re doing it correctly, such that then you can downstream, build with confidence, the mapping between the neural spikes and the intended action.
And by doing the action correctly, what I really mean is, at this level of resolution of what neurons are doing. So if, in ideal world, you could get a signal of behavioral intent that is ground truth accurate at the scale of one millisecond resolution, then with high confidence, I could build a mapping from my neural spikes, to that behavioral intention. But the challenge is again, that you don’t observe what they’re actually doing. And so there’s a lot of nuance to how you build user experiences, that give you more than just a course on average correct representation of what the user’s intending to do.
If you want to build the world’s best mouse, you really want it to be as responsive as possible. You want it to be able to do exactly what the user’s intending, at every step along the way, not just on average be correct, when you’re trying to move it from left to right. And building a behavioral calibration game, or our software experience, that gives you that level of resolution, is what we spend a lot of time working on.
Lex Fridman
So the calibration process, the interface, has to encourage precision. Meaning whatever it does, it should be super intuitive that the next thing the human is going to likely do, is exactly that intention that you need, and only that intention?

… it’s how it works, for the calibration. And calibration, at least at this stage of Neuralink is fundamental to the operation of the thing? And not just calibration, but continued calibration essentially?

Intention vs action
Lex Fridman
Wow, yeah.
Wow, yeah.
Bliss Chapman
You said something that I think is worth exploring there a little bit. You said it’s primarily a UX challenge, and I think a large component of it is, but there is also a very interesting machine learning challenge here. Which is given some dataset, including some on average correct behavior, of asking the user to move up, or move down, move right, move left, and given a dataset of neural spikes. Is there a way to infer, in some kind of semi-supervised, or entirely unsupervised way, what that high resolution version of their intention is?

Is there a way to infer, in some kind of semi-supervised, or entirely unsupervised way, what that high resolution version of their intention is?
And if you think about it, there probably is, because there are enough data points in the dataset, enough constraints on your model. That there should be a way with the right sort of formulation, to let the model figure out itself, for example… At this millisecond, this is exactly how hard they’re pushing upwards, and at this millisecond, this is how hard they’re trying to push upwards.
Lex Fridman
It’s really important to have very clean labels, yes? So the problem becomes much harder from the machine learning perspective if the labels are noisy?

Bliss Chapman
That’s correct.
That’s correct.
Lex Fridman
And then to get the clean labels, that’s a UX challenge?
And then to get the clean labels, that’s a UX challenge?
Bliss Chapman
Correct. Although clean labels, I think maybe it’s worth exploring what that exactly means. I think any given labeling strategy will have some number of assumption to make, about what the user is attempting to do. Those assumptions can be formulated in a loss function, or they can be formulated in terms of heuristics that you might use, to just try to estimate or guesstimate what the user’s trying to do. And what really matters is, how accurate are those assumptions? For example, you might say, “Hey, user, push upwards and follow the speed of this cursor.” And your heuristic might be that they’re trying to do exactly what that cursor is trying to do.

For example, you might say, “Hey, user, push upwards and follow the speed of this cursor.” And your heuristic might be that they’re trying to do exactly what that cursor is trying to do.
Another competing heuristic might be, they’re actually trying to go slightly faster at the beginning of the movement and slightly slower at the end. And those competing heuristics may or may not be accurate reflections of what the user is trying to do. Another version of the task might be, “Hey, user, imagine moving this cursor a fixed offset.” So rather than follow the cursor, just try to move it exactly 200 pixels to the right. So here’s the cursor, here’s the target, okay, cursor disappears, try to move that now invisible cursor, 200 pixels to the right. And the assumption in that case would be that the user can’t actually modulate correctly that position offset.
But that position offset assumption might be a weaker assumption, and therefore potentially, you can make it more accurate, than these heuristics that are trying to guesstimate at each millisecond what the user’s trying to do. So you can imagine different tasks that make different assumptions about the nature of the user intention. And those assumptions being correct is what I would think of as a clean label.
Lex Fridman
For that step, what are we supposed to be visualizing? There’s a cursor, and you want to move that cursor to the right, or the left, or up and down, or maybe move them by a certain offset. So that’s one way. Is that the best way to do calibration?

So for example, an alternative crazy way that probably is playing a role here, is a game like WEG Grid. Where you’re just getting a very large amount of data, the person playing a game. Where if they’re in a state of flow, maybe you can get clean signal as a side effect?
Bliss Chapman
Yep.
Yep.
Lex Fridman
Or is that not an effective way for initial calibration?
Or is that not an effective way for initial calibration?
Bliss Chapman
Yeah. Great question. There’s a lot to unpack there. So the first thing I would draw a distinction between is, open loop versus closed loop. So open loop, what I mean by that is, the user is sort of going from zero to one. They have no model at all, and they’re trying to get to the place where they have some level of control, at all. In that setup, you really need to have some task that gives the user a hint of what you want them to do, such that you can build its mapping again, from brain data to output. Then once they have a model, you could imagine them using that model and actually adapting to it, and figuring out the right way to use it themself. And then retraining on that data to give you sort of a boost in performance.

Then once they have a model, you could imagine them using that model and actually adapting to it, and figuring out the right way to use it themself. And then retraining on that data to give you sort of a boost in performance.
There’s a lot of challenges associated with both of these techniques, and we can rabbit hole into both of them if you’re interested. But the sort of challenge with the open loop task is that the user themself doesn’t get proprioceptive feedback about what they’re doing. They don’t necessarily perceive themself or feel the mouse under their hand, when they’re trying to do an open loop calibration. They’re being asked to perform something… Imagine if you sort of had your whole right arm numbed, and you stuck it in a box and you couldn’t see it, so you had no visual feedback and you had no proprioceptive feedback, about what the position or activity of your arm was.
And now you’re asked, “Okay, given this thing on the screen, that’s moving from left to right, match that speed?” And you basically can try your best to invoke whatever that imagined action is in your brain, that’s moving the cursor from left to right. But in any situation, you’re going to be inaccurate and maybe inconsistent in how you do that task. And so that’s sort of the fundamental challenge of open loop. The challenge with closed loop is that once the user’s given a model, and they’re able to start moving the mouse on their own, they’re going to very naturally adapt to that model. And that coadaptation between the model learning what they’re doing, and the user learning how to use the model, may not find you the best sort of global minima.
And maybe that your first model was noisy in some ways, or maybe just had some quirk. There’s some part of the data distribution, it didn’t cover super well, and the user now figures out, because they’re a brilliant user like Noland, they figure out the right sequence of imagined motions, or the right angle they have to hold their hand at to get it to work. And they’ll get it to work great, but then the next day they come back to their device, and maybe they don’t remember exactly all the tricks that they used the previous day. And so there’s a complicated sort of feedback cycle here that can emerge, and can make it a very, very difficulty debugging process.
Lex Fridman
Okay. There’s a lot of really fascinating things there. Actually, just to stay on the closed loop… I’ve seen situations, this actually happened watching psychology grad students. They used a piece of software and they don’t know how to program themselves. They used a piece of software that somebody else wrote, and it has a bunch of bugs, and they’ve been using it for years. They figure out ways to walk around, “Oh, that just happens.” Nobody considers, “Maybe we should fix this.” They just adapt. And that’s a really interesting notion, that we’re really good at it adapting, but that might not be the optimal?

Lex Fridman
Okay. So how do you solve that problem? Do you have to restart from scratch every once in a while, kind of thing?
Okay. So how do you solve that problem? Do you have to restart from scratch every once in a while, kind of thing?
Bliss Chapman
Yeah. It’s a good question. First and foremost, I would say this is not a solve problem. And for anyone who’s listening in academia who works on BCIs, I would also say this is not a problem that’s solved by simply scaling channel count. So maybe that can help, and you can get sort of richer covariant structures that you can use to exploit, when trying to come up with good labeling strategies. But if you’re interested in problems that aren’t going to be solved inherently by scaling channel count, this is one of them.

But if you’re interested in problems that aren’t going to be solved inherently by scaling channel count, this is one of them.
Yeah. So how do you solve it? It’s not a solve problem. That’s the first thing I want to make sure it gets across. The second thing is, any solution that involves closed loop is going to become a very difficult debugging problem. And one of my general heuristics for choosing what prompts to tackle is, that you want to choose the one that’s going to be the easiest to debug. Because if you can do that, even if the ceiling is lower, you’re going to be able to move faster, because you have a tighter iteration loop debugging the problem.
In the open loop setting, there’s not a feedback cycle to debug with the user in the loop. And so there’s some reason to think that, that should be an easier debugging problem. The other thing that’s worth understanding is that even in the closed loop setting, there’s no special software magic of how to infer what the user is truly attempting to do. In the closed loop setting, although they’re moving the cursor on the screen, they may be attempting something different than what your model is outputting. So what the model is outputting is not a signal that you can use to retrain if you want to be able to improve the model further. You still have this very complicated guestimation, or unsupervised problem of figuring out what is the true user intention underlying that signal?
And so the open loop problem has the nice property of being easy to debug, and the second nice property of, it has all the same information and content as the closed loop scenario. Another thing I want to mention and call out, is that this problem doesn’t need to be solved in order to give useful control to people. Even today with the solutions we have now, and that academia has built up over decades, the level of control that can be given to a user today, is quite useful. It doesn’t need to be solved to get to that level of control.
But again, I want to build the world’s best mouse. I want to make it so good that it’s not even a question that you want it. And to build the world’s best mouse, the superhuman version, you really need to nail that problem. And a couple maybe details of previous studies that we’ve done internally, that I think are very interesting to understand, when thinking about how to solve this problem. The first is that even when you have ground-truth data of what the user’s trying to do, and you can get this with an able-bodied monkey, a monkey that has a Neuralink device implanted, and moving a mouse to control a computer. Even with that ground-truth dataset, it turns out that the optimal thing to predict to produce high performance BCI, is not just the direct control of the mouse.
You can imagine building a dataset of what’s going on in the brain, and what is the mouse exactly doing on the table? And it turns out that if you build the mapping from neurospikes to predict exactly what the mouse is doing, that model will perform worse, than a model that is trained to predict higher level assumptions about what the user might be trying to do. For example, assuming that the monkey is trying to go in a straight line to the target, it turns out that making those assumptions is actually more effective in producing a model, than actually predicting the underlying hand movement.
Lex Fridman
So the intention, not the physical movement, or whatever?
So the intention, not the physical movement, or whatever?
Bliss Chapman
Yeah.
Yeah.
Lex Fridman
There’s obviously a really strong correlation between the two, but the intention is a more powerful thing to be chasing?
There’s obviously a really strong correlation between the two, but the intention is a more powerful thing to be chasing?
Bliss Chapman
Right.
Right.
Lex Fridman
Well, that’s also super interesting. I mean, the intention itself is fascinating because yes, with the BCI here in this case with the digital telepathy, you’re acting on the intention, not the action. Which is why there’s an experience of feeling like it’s happening before you meant for it to happen? That is so cool. And that is why you could achieve superhuman performance problem, in terms of the control of the mouse? So for open loop, just to clarify, so whenever the person is tasked to move the mouse to the right, you said there’s not feedback, so they don’t get to get that satisfaction of actually getting it to move? Right?

So you could imagine giving the user feedback on a screen, but it’s difficult, because at this point you don’t know what they’re attempting to do. So what can you show them that would basically give them a signal of, “I’m doing this correctly or not correctly?” So let’s take a very specific example. Maybe your calibration task looks like you’re trying to move the cursor, a certain position offset. So your instructions to the user are, “Hey, the cursor’s here. Now when the cursor disappears, imagine you’re moving it 200 pixels from where it was, to the right to be over this target.”

Now when the cursor disappears, imagine you’re moving it 200 pixels from where it was, to the right to be over this target.”
In that kind of scenario, you could imagine coming up with some sort of consistency metric that you could display to the user of, “Okay, I know what the spike trend looks like on average when you do this action to the right. Maybe I can produce some sort of probabilistic estimate of how likely is that to be the action you took, given the latest trial or trajectory that you imagined?” And that could give the user some sort of feedback of how consistent are they, across different trials.
You could also imagine that if the user is prompted with that kind of consistency metric, that maybe they just become more behaviorally engaged to begin with, because the task is kind of boring when you don’t have any feedback at all. And so there may be benefits to the user experience of showing something on the screen, even if it’s not accurate. Just because it keeps the user motivated to try to increase that number, or push it upwards.
Lex Fridman
So there’s this psychology element here?
So there’s this psychology element here?
Bliss Chapman

Yeah. Absolutely.
Calibration
Lex Fridman
And again, all of that is UX challenge? How much signal drift is there hour-to-hour, day-to-day, week-to-week, month-to-month? How often do you have to recalibrate because of the signal drift?
And again, all of that is UX challenge? How much signal drift is there hour-to-hour, day-to-day, week-to-week, month-to-month? How often do you have to recalibrate because of the signal drift?
Bliss Chapman
Yeah. So this is a problem we’ve worked on both with NHP, non-human primates, before our clinical trial, and then also with Noland during the clinical trial. Maybe the first thing that’s worth stating is what the goal is here. So the goal is really to enable the user to have a plug and play experience… Well, I guess they don’t have to plug anything in, but a play experience where they can use the device whenever they wanted, however they want to. And that’s really what we’re aiming for. And so there can be a set of solutions that get to that state without considering this non-stationary problem.

And that’s really what we’re aiming for. And so there can be a set of solutions that get to that state without considering this non-stationary problem.
So maybe the first solution here that’s important, is that they can recalibrate whenever they want. This is something that Noland has the ability to do today, so he can recalibrate the system at 2:00 AM, in the middle of the night without his caretaker, or parents or friends around, to help push a button for him. The other important part of the solution is that when you have a good model calibrated, that you can continue using that without needing to recalibrate it. So how often he has to do this recalibration to-date, depends really on his appetite for performance.
We observe sort of a degradation through time, of how well any individual model works, but this can be mitigated behaviorally by the user adapting their control strategy. It can also be mitigated through a combination of software features that we provide to the user. For example, we let the user adjust exactly how fast the cursor is moving. We call that the gain, for example, the gain of how fast the cursor reacts to any given input intention.
They can also adjust the smoothing, how smooth the output of that cursor intention actually is. That can also adjust the friction, which is how easy is it to stop and hold still? And all these software tools allow the user a great deal of flexibility and troubleshooting mechanisms to be able to solve this problem for themselves.
Lex Fridman
By the way, all of this is done by looking to the right side of the screen, selecting the mixer. And the mixer you have, it’s-

I mean, it’s a really well done interface. It’s really, really well done. And so there’s that bias that there’s a cursor drift that Noland talked about in a stream. Although he said that you guys were just playing around with it with him, and then constantly improving. So that could have been just a snapshot of that particular moment, a particular day, where he said that there was this cursor drift and this bias that could be removed by him. I guess, looking to the right side of the screen, or left side of the screen, to adjust the bias?

Bliss Chapman
Yeah. So this is actually an idea that comes out of academia. There is some prior work with BrainGate clinical trial participants where they pioneered this idea of bias correction. The way we’ve done it, I think is, it’s very prioritized, very beautiful user experience. Where the user can essentially flash the cursor over to the side of the screen, and it opens up a window, where they can actually adjust or tune exactly the bias of the cursor. So bias, maybe for people who aren’t familiar, is just sort of what is the default motion of the cursor, if you’re imagining nothing? And it turns out that, that’s one of the first sort-

Lex Fridman
It’s very poetic. I love it. The qualia of the cursor experience. Yeah, I mean it sounds poetic, but it is deeply true. There is an experience. When it works well, it is a joyful… A really pleasant experience. And when it doesn’t work well, it’s a very frustrating experience. That’s actually the art of UX, you have the possibility to frustrate people, or the possibility to give them joy.

Bliss Chapman
And at the end of the day, it really is truly the case that UX is how the thing works. And so it’s not just what’s showing on the screen, it’s also, what control surfaces does a decoder provide the user? We want them to feel like they’re in the F1 car, not like some minivan. And that really truly is how we think about it. Noland himself is an F1 fan. We refer to ourself as a pit crew, he really is truly the F1 driver. And there’s different control surfaces that different kinds of cars and airplanes provide the user, and we take a lot of inspiration from that when designing how the cursor should behave.

And there’s different control surfaces that different kinds of cars and airplanes provide the user, and we take a lot of inspiration from that when designing how the cursor should behave.
And maybe one nuance of this is, even details like when you move a mouse on a MacBook trackpad, the sort of response curve of how that input that you give the trackpad translates to cursor movement is different than how it works with a mouse. When you move on the trackpad, there’s a different response function, a different curve to how much a movement translates to input to the computer than when you do it physically with a mouse. And that’s because somebody sat down a long time ago, when they’re designing the initial input systems to any computer, and they thought through exactly how it feels to use these different systems. And now we’re designing the next generation of this, input system to a computer, which is entirely done via the brain, and there’s no proprioceptive feedback, again, you don’t feel the mouse in your hand, you don’t feel the keys under your fingertips, and you want a control surface that still makes it easy and intuitive for the user to understand the state of the system, and how to achieve what they want to achieve. And ultimately the end goal is that that UX is completely… It fades in the background, it becomes something that’s so natural and intuitive that it’s subconscious to the user, and they just should feel like they have basically direct control over the cursor, just does what they want it to do. They’re not thinking about the implementation of how to make it do what they want it to do, it’s just doing what they want it to do.
Lex Fridman
Is there some kind of things along the lines of like Fitt’s Law, where you should move the mouse in a certain kind of way that maximizes your chance to hit the target? I don’t even know what I’m asking, but I’m hoping the intention of my question will land on a profound answer. No. Is there some kind of understanding of the laws of UX when it comes to the context of somebody using their brain to control it that’s different than with a mouse?

Bliss Chapman
I think we’re in the early stages of discovering those laws, so I wouldn’t claim to have solved that problem yet, but there’s definitely some things we’ve learned that make it easier for the user to get stuff done. And it’s pretty straightforward when you verbalize it, but it takes a while to actually get to that point, when you’re in the process of debugging the stuff in the trenches.

And it’s pretty straightforward when you verbalize it, but it takes a while to actually get to that point, when you’re in the process of debugging the stuff in the trenches.
One of those things is that any machine learning system that you build has some number of errors, and it matters how those errors translate to the downstream user experience. For example, if you’re developing a search algorithm in your photos, if you search for your friend, Joe, and it pulls up a photo of your friend, Josephine, maybe that’s not a big deal, because the cost of an error is not that high. In a different scenario, where you’re trying to detect insurance fraud or something like this, and you’re directly sending someone to court because of some machine learning model output, then the errors make a lot more sense to be careful about, you want to be very thoughtful about how those errors translate to downstream effects.
The same is true in BCI. So for example, if you’re building a model that’s decoding a velocity output from the brain, versus an output where you’re trying to modulate the left click for example, these have sort of different trade-offs of how precise you need to be before it becomes useful to the end user. For velocity, it’s okay to be on average correct, because the output of the model is integrated through time. So if the user’s trying to click at position A, and they’re currently position B, they’re trying to navigate over time to get between those two points. And as long as the output of the model is on average correct, they can sort of steer it through time, with the user control loop in the mix, they can get to the point they want to get to.
The same is not true of a click. For a click, you’re performing it almost instantly, at the scale of neurons firing. And so you want to be very sure that that click is correct, because a false click can be very destructive to the user. They might accidentally close the tab that they’re trying to do something in, and lose all their progress. They might accidentally hit some send button on some text that there’s only half composed and reads funny after. So there’s different sort of cost functions associated with errors in this space, and part of the UX design is understanding how to build a solution that is, when it’s wrong, still useful to the end user.
Lex Fridman
It’s so fascinating, assigning cost to every action when an error occurs. So every action, if an error occurs, has a certain cost, and incorporating that into how you interpret the intention, mapping it to the action is really important. I didn’t quite, until you said it, realize there’s a cost to sending the text early. It’s a very expensive cost.

Yeah, it’s super annoying if you accidentally… Imagine if your cursor misclicked every once in a while. That’s super obnoxious. And the worst part of it is, usually when the user’s trying to click, they’re also holding still, because they’re over the target they want to hit, and they’re getting ready to click, which means that in the datasets that we build, on average is the case that sort of low speeds, or desire to hold still, is correlated with when the user’s attempting to click.

Lex Fridman
Wow, that is really fascinating.
Wow, that is really fascinating.

People think that, “Oh, a click is a binary signal, this must be super easy to decode.” Well, yes, it is, but the bar is so much higher for it to become a useful thing for the user. And there’s ways to solve this. I mean, you can sort of take the compound approach of, “Well, let’s take five seconds to click. Let’s take a huge window of time, so we can be very confident about the answer.” But again, world’s best mouse. The world’s best mouse doesn’t take a second to click, or 500 milliseconds to click, it takes five milliseconds to click or less. And so if you’re aiming for that kind of high bar, then you really want to solve the underlying problem.

Webgrid
Lex Fridman
So maybe this is a good place to ask about how to measure performance, this whole bits per second. Can you explain what you mean by that? Maybe a good place to start is to talk about Webgrid as a game, as a good illustration of the measurement of performance.

Bliss Chapman
Yeah. Maybe I’ll take one zoom out step there, which is just explaining why we care to measure this at all. So again, our goal is to provide the user the ability to control the computer as well as I can, and hopefully better. And that means that they can do it at the same speed as what I can do, it means that they have access to all the same functionality that I have, including all those little details like command tab, command space, all this stuff, they need to be able to do it with their brain, and with the same level of reliability as what I can do with my muscles. And that’s a high bar, and so we intend to measure and quantify every aspect of that to understand how we’re progressing towards that goal.

And that’s a high bar, and so we intend to measure and quantify every aspect of that to understand how we’re progressing towards that goal.
There’s many ways to measure BPS by the way, this isn’t the only way, but we present the user a grid of targets, and basically we compute a score which is dependent on how fast and accurate they can select, and then how small are the targets. And the more targets that are on the screen, the smaller they are, the more information you present per click. And so if you think about it from information theory point of view, you can communicate across different information theoretic channels, and one such channel is a typing interface, you can imagine, that’s built out of a grid, just like a software keyboard on the screen.
And bits per second is a measure that’s computed by taking the log of the number of targets on the screen. You can subtract one if you care to model a keyboard, because you have to subtract one for the delete key on the keyboard. But log of the number of targets on the screen, times the number of correct selections, minus incorrect, divided by some time window, for example, 60 seconds. And that’s sort of the standard way to measure a cursor control task in academia. And all credit in the world goes to this great professor, Dr. Shenoy of Stanford who came up with that task, and he’s also one of my inspirations for being in the field. So all the credit in the world to him for coming up with a standardized metric to facilitate this kind of bragging rights that we have now to say that Noland is the best in the world at this task with this BCI. It’s very important for progress that you have standardized metrics that people can compare across. Different techniques and approaches, how well does this do? So big kudos to him and to all the team at Stanford.
Yeah, so for Noland, and for me playing this task, there’s also different modes that you can configure this task. So the Webgrid task can be presented as just sort of a left click on the screen, or you could have targets that you just dwell over, or you could have targets that you left, right click on, you could have targets that are left, right click, middle click, scrolling, clicking and dragging. You can do all sorts of things within this general framework, but the simplest, purest form is just blue targets show up on the screen, blue means left click. That’s the simplest form of the game.
And the sort of prior records here in academic work and at Neuralink internally with NHPs have all been matched or beaten by Noland with his Neuralink device. So prior to Neuralink, the world record for a human using device is somewhere between 4.2 to 4.6 BPS, depending on exactly what paper you read and how you interpret it. Noland’s current record is 8.5 BPS. and again, this sort of median Neuralinker performance is 10 BPS. So you can think of it roughly as, he’s 85% the level of control of a median Neuralinker using their cursor to select blue targets on the screen.
I think there’s a very interesting journey ahead to get us to that same level of 10 BPS performance. It’s not the case that the tricks that got us from 4 to 6 BPS, and then 6 to 8 BPS are going to be the ones that get us from 8 to 10. And in my view, the core challenge here is really the labeling problem. It’s how do you understand, at a very, very fine resolution, what the user’s attempting to do? And I highly encourage folks in academia to work on this problem.
Lex Fridman
What’s the journey with Noland on that quest of increasing the BPS on Webgrid? In March, you said that he selected 89,285 targets in Webgrid. So he loves this game, he’s really serious about improving his performance in this game. So what is that journey of trying to figure out how to improve that performance? How much can that be done on the decoding side? How much can that be done on the calibration side? How much can that be done on the Noland side of figuring out how to convey his intention more cleanly?

Bliss Chapman
Yeah. No, this is a great question. So in my view, one of the primary reasons why Noland’s performance is so good is because of Noland. Noland is extremely focused and very energetic. He’ll play Webgrid sometimes for four hours in the middle of the night. From 2:00 A.M. To 6:00 A.M. he’ll be playing Webgrid, just because he wants to push it to the limits of what he can do. This is not us asking him to do that, I want to be clear. We’re not saying, ” Hey, you should play Webgrid tonight.” We just gave him the game as part of our research, and he is able to play it independently, and practice whenever he wants, and he really pushes hard to push it, the technology’s absolute limit. And he views that as his job, really, to make us be the bottleneck. And boy, has he done that well.

And he views that as his job, really, to make us be the bottleneck. And boy, has he done that well.
And so the first thing to acknowledge is that he’s extremely motivated to make this work. I’ve also had the privilege to meet other clinical trial participants from BrainGate and other trials, and they very much shared the same attitude of, they viewed this as their life’s work to advance the technology as much as they can. And if that means selecting targets on the screen for four hours from 2:00 A.M. to 6:00 A.M., then so be it. And there’s something extremely admirable about that that’s worth calling out.
Okay, so then how do you get from where he started, which is no cursor control to eight BPS? I mean, when he started, there’s a huge amount of learning to do on his side and our side to figure out what’s the most intuitive control for him. And the most intuitive control for him is, you have to find the set intersection of, “Do we have the signal to decode?” So we don’t pick up every single neuron in the motor cortex, which means we don’t have representation for every part of the body. So there may be some signals that we have better decode performance on than others. For example, on his left hand, we have a lot of difficulty distinguishing his left ring finger from his left middle finger, but on his right hand, we have a good control and good modulation detected from the neurons that were able to record for his pinky, and his thumb, and his index finger. So you can imagine how these different subspaces of modulated activity intersect with what’s the most intuitive for him.
And this has evolved over time, so once we gave him the ability to calibrate models on his own, he was able to go and explore various different ways to imagine controlling the cursor. For example, he can imagine controlling the cursor by wiggling his wrist side to side, or by moving his entire arm, by… I think at one point he did his feet. He tried a whole bunch of stuff to explore the space of what is the most natural way for him to control the cursor, that at the same time, it’s easy for us to decode-
Lex Fridman
Just to clarify, it’s through the body mapping procedure there, you’re able to figure out which finger he can move?
Just to clarify, it’s through the body mapping procedure there, you’re able to figure out which finger he can move?
Bliss Chapman
Yes. Yeah, that’s one way to do it. Maybe one nuance of the… When he’s doing it, he can imagine many more things than we represent in that visual on the screen. So we show him, sort of abstractly, “Here’s a cursor. You figure out what works the best for you.” And we obviously have hints about what will work best from that body mapping procedure, of, “We know that this particular action we can represent well.” But it’s really up to him to go and explore and figure out what works the best.

But at which point does he no longer visualize the movement of his body, and is just visualizing the movement of the cursor?

So this happened on a Tuesday. I remember this day very clearly, because at some point during the day, it looked like he wasn’t doing super well, it looked like the model wasn’t performing super well, and he was getting distracted, but actually, it wasn’t the case. What actually happened was, he was trying something new, where he was just controlling the cursor, so he wasn’t imagining moving his hand anymore, he was just imagining… I don’t know what it is, some abstract intention to move the cursor on the screen, and I cannot tell you what the difference between those two things are, I truly cannot. He’s tried to explain it to me before, I cannot give a first-person account of what that’s like. But the expletives that he uttered in that moment were enough to suggest that it was a very qualitatively different experience for him to just have direct neural control over a cursor.

Lex Fridman
I wonder if there’s a way through UX to encourage a human being to discover that, because he discovered it… Like you said to me, that he’s a pioneer. So he discovered that on his own through all of this, the process of trying to move the cursor with different kinds of intentions. But that is clearly a really powerful thing to arrive at, which is to let go of trying to control the fingers and the hand, and control the actual digital device with your mind.

That’s right. UX is how it works. And the ideal UX is one that the user doesn’t have to think about what they need to do in order to get it done, it just does it.

Lex Fridman
That is so fascinating. But I wonder, on the biological side, how long it takes for the brain to adapt. So is it just simply learning high level software, or is there a neuroplasticity component where the brain is adjusting slowly?

Bliss Chapman
Yeah. The truth is, I don’t know. I’m very excited to see with sort of the second participant that I implant, what the journey is like for them, because we’ll have learned a lot more, potentially, we can help them understand and explore that direction more quickly. This wasn’t me prompting Noland to go try this, he was just exploring how to use his device and figured it out himself. But now that we know that that’s a possibility, that maybe there’s a way to, for example, hint the user, “Don’t try super hard during calibration, just do something that feels natural.” Or, “Just directly control the cursor. Don’t imagine explicit action.” And from there, we should be able to hopefully understand how this is for somebody who has not experienced that before. Maybe that’s the default mode of operation for them, you don’t have to go through this intermediate phase of explicit motions.

Or maybe if that naturally happens for people, you can just occasionally encourage them to allow themselves to move the cursor.

Bliss Chapman
Yeah. Just to comment on that too, we’ve probably tried 1,000 different ways to do various aspects of decoding, and now we know what the right subspace is to continue exploring further. Again, thanks to Noland and the many hours he’s put into this. And so even just that, help constraints, or the beam search of different approaches that we could explore really helps accelerate for the next person the set of things that we’ll get to try on day one, how fast we hopefully get them to use for control, how fast we can enable them to use it independently, and to get value out of the system. So massive hats off to Noland and all the participants that came before to make this technology a reality.

Lex Fridman
So how often are the updates to the decoder? ‘Cause Noland mentioned, “Okay, there’s a new update that we’re working on.” In the stream he said he plays the snake game, because it’s super hard, it’s a good way for him to test how good the update is. And he says sometimes the update is a step backwards, it’s a constant iteration. What does the update entail? Is it mostly on the decoder side?

Bliss Chapman
Yeah. Couple of comments. So, one, it’s probably worth drawing distinction between research sessions where we’re actively trying different things to understand what the best approach is, versus independent use, where we wanted to have ability to just go use the device how anybody would want to use their MacBook. So what he’s referring to is, I think, usually in the context of a research session, where we’re trying many, many different approaches to… Even unsupervised approaches, like we talked about earlier, to try to come up with better ways to estimate his true intention, and more accurately decoded.

And in those scenarios, we try, in any given session… He’ll sometimes work for eight hours a day, and so that can be hundreds of different models that we would try in that day. A lot of different things. Now, it’s also worth noting that we update the application he uses quite frequently, I think sometimes up to 4 or 5 times a day, we’ll update his application with different features, or bug fixes, or feedback that he’s given us.
He’s a very articulate person who is part of the solution, he’s not a complaining person, he says, “Hey, here’s this thing that I’ve discovered is not optimal in my flow. Here’s some ideas how to fix it. Let me know what your thoughts are, let’s figure out how to solve it.” And it often happens that those things are addressed within a couple of hours of him giving us his feedback, that’s the kind of iteration cycle we’ll have. And so sometimes at the beginning of the session, he’ll give us feedback, and at the end of the session he’s giving us feedback on the next iteration of that process or that setup.
Lex Fridman
That’s fascinating, ’cause one of the things you mentioned that there was 271 pages of notes taken from the BCI sessions, and this was just in March. So one of the amazing things about human beings that they can provide… Especially ones who are smart, and excited, and all positive and good vibes like Noland, that they can provide feedback, continuous feedback.

Bliss Chapman
Yeah. Just to brag on the team a little bit, I work with a lot of exceptional people, and it requires the team being absolutely laser-focused on the user, and what will be the best for them. And it requires a level of commitment of, “Okay, this is what the user feedback was. I have all these meetings, we’re going to skip that today, and we’re going to do this.” That level of focus and commitment is, I would say, underappreciated in the world. And also, you obviously have to have the talent to be able to execute on these things effectively, and we have that in loads.

Yeah, and this is such an interesting space of UX design, because there’s so many unknowns here. And I can tell UX is difficult because of how many people do it poorly. It’s just not a trivial thing.
Yeah, and this is such an interesting space of UX design, because there’s so many unknowns here. And I can tell UX is difficult because of how many people do it poorly. It’s just not a trivial thing.
Bliss Chapman
Yeah. UX is not something that you can always solve by just constant iterating on different things. Sometimes you really need to step back and think globally, “Am I even in the right sort of minima to be chasing down for a solution?” There’s a lot of problems in which sort of fast iteration cycle is the predictor of how successful you’ll be. As a good example, like in an RL simulation for example, the more frequently you get reward, the faster you can progress. It’s just an easier learning problem the more frequently you get feedback. But UX is not that way, I mean, users are actually quite often wrong about what the right solution is, and it requires a deep understanding of the technical system, and what’s possible, combined with what the problem is you’re trying to solve. Not just how the user expressed it, but what the true underlying problem is to actually get to the right place.

Lex Fridman
Yeah, that’s the old stories of Steve Jobs rolling in there, like, “Yeah, the user is a useful signal, but it’s not a perfect signal, and sometimes you have to remove the floppy disc drive.” Or whatever the… I forgot all the crazy stories of Steve Jobs making wild design decisions. But there, some of it is aesthetic, that some of it is about the love you put into the design, which is very much a Steve Jobs, Johnny Ive type thing, but when you have a human being using their brain to interact with it, it also is deeply about function, it’s not just aesthetic. And that, you have to empathize with a human being before you, while not always listening to them directly. You have to deeply empathize. It’s fascinating. It’s really, really fascinating. And at the same time, iterate, but not iterate in small ways, sometimes a complete… Like rebuilding the design. Noland said in the early days the UX sucked, but you improved quickly. What was that journey like?

Yeah, I mean, I’ll give you one concrete example. So he really wanted to be able to read manga. This is something that he… I mean, it sounds like a simple thing, but it’s actually a really big deal for him, and he couldn’t do it with his mouse stick. It wasn’t accessible, you can’t scroll with the mouse stick on his iPad on the website that he wanted to be able to use to read the newest manga, and so-

Lex Fridman
It’s exhausting, it hurts, and it’s inefficient.
It’s exhausting, it hurts, and it’s inefficient.
Bliss Chapman
Yeah. And maybe it’s also worth calling out, there are other alternative assisted technologies, but the particular situation Noland’s in, and this is not uncommon, and I think it’s also not well-understood by folks, is that he’s relatively spastic, so he’ll have muscle spasms from time to time. And so any assistive technology that requires him to be positioned directly in front of a camera, for example, an eye tracker, or anything that requires him to put something in his mouth just is a no-go, ’cause he’ll either be shifted out of frame when he has a spasm, or if he has something in his mouth, it’ll stab him in the face if he spasms too hard. So these kinds of considerations are important when thinking about what advantages a BCI has in someone’s life. If it fits ergonomically into your life in a way that you can use it independently when your caretakers not there, wherever you want to, either in the bed or in the chair, depending on your comfort level and your desire to have pressure source, all these factors matter a lot in how good the solution is in that user’s life.
Yeah.

So one of these very fun examples is scroll. So, again, manga is something he wanted to be able to read, and there’s many ways to do scroll with a BCI. You can imagine different gestures, for example, the user could do that would move the page. But scroll is a very fascinating control surface, because it’s a huge thing on the screen in front of you. So any sort of jitter in the model output, any sort of air in the model output causes an earthquake on the screen. You really don’t want to have your mango page that you’re trying to read be shifted up and down a few pixels just because your scroll decoder is not completely accurate.
And so this was an example where we had to figure out how to formulate the problem in a way that the errors of the system, whenever they do occur, and we’ll do our best to minimize them, but whenever those errors do occur, that it doesn’t interrupt the qualia, again, of the experience that the user is having. It doesn’t interrupt their flow of reading their book. And so what we ended up building is this really brilliant feature. This is a teammate named Bruce who worked on this really brilliant work called Quick Scroll. And Quick Scroll basically looks at the screen, and it identifies where on the screen are scroll bars. And it does this by deeply integrated with macOS to understand where are the scroll bars actively present on the screen, using the sort of accessibility tree that’s available to macOS apps. And we identified where those scroll bars are, and we provided a BCI scroll bar, and the BCI scroll bar looks similar to a normal scroll bar, but it behaves very differently, in that once you move over to it, your cursor sort of morphs onto it, it sort of attaches or latches onto it. And then once you push up or down, in the same way that you’d use a push to control the normal cursor, it actually moves the screen for you. So it’s basically like remapping the velocity to a scroll action.
And the reason that feels so natural and intuitive is that when you move over to attach to it feels like magnetic, so you’re sort of stuck onto it, and then it’s one continuous action, you don’t have to switch your imagined movement, you sort of snap onto it, and then you’re good to go. You just immediately can start pulling the page down or pushing it up. And even once you get that right, there’s so many little nuances of how the scroll behavior works to make it natural and intuitive. So one example is momentum. When you scroll a page with your fingers on the screen, you actually have some flow, it doesn’t just stop right when you lift your finger up. The same is true with BCI scroll, so we had to spend some time to figure out, “What are the right nuances when you don’t feel the screen under your fingertip anymore? What is the right sort of dynamic, or what’s the right amount of page give, if you will, when you push it to make it flow the right amount for the user to have a natural experience reading their book?”
I could tell you there’s so many little minutia of how exactly that scroll works, that we spent probably a month getting right, to make that feel extremely natural and easy for the user to navigate.
Lex Fridman
I mean, even the scroll on a smartphone with your finger feels extremely natural and pleasant, and it probably takes an extremely long time to get that right. And actually, the same kind of visionary UX design that we were talking about, don’t always listen to the users, but also listen to them, and also have visionary, big, like throw everything out, think from first principles, but also not. Yeah, yeah. By the way, it just makes me think that scroll bars on the desktop probably have stagnated, and never taken that… ‘Cause the snap, same as snap to grid, snap to scroll bar action you’re talking about is something that could potentially be extremely useful in the desktop setting, even just for users to just improve the experience. ‘Cause the current scroll bar experience in the desktop is horrible.

Bliss Chapman
Yep. Agreed.
Yep. Agreed.
Lex Fridman
It’s hard to find, hard to control, there’s not a momentum, there’s… And the intention should be clear, when I start moving towards a scroll bar, there should be a snapping to the scroll bar action, but of course… Maybe I’m okay paying that cost, but there’s hundreds of millions of people paying that cost non-stop, but anyway. But in this case, this is necessary, because there’s an extra cost paid by Noland for the jitteriness, so you have to switch between the scrolling and the reading. There has to be a face shift between the two, like when you’re scrolling, you’re scrolling.

Right, right. So that is one drawback of the current approach. Maybe one other just sort of case study here. So, again, UX is how it works, and we think about that holistically, from the… Even the feature detection level of what we detect in the brain, to how we design the decoder, what we choose to decode, to then how it works once it’s being used by the user. So another good example in that sort of how it works once they’re actually using the decoder, the output that’s displayed on the screen is not just what the decoder says, it’s also a function of what’s going on on the screen.

So another good example in that sort of how it works once they’re actually using the decoder, the output that’s displayed on the screen is not just what the decoder says, it’s also a function of what’s going on on the screen.
So we can understand, for example, that when you’re trying to close a tab, that very small, stupid little X that’s extremely tiny, which is hard to get precisely hit, if you’re dealing with a noisy output of the decoder, we can understand that that is a small little X you might be trying to hit, and actually make it a bigger target for you. Similar to how when you’re typing on your phone, if you are used to the iOS keyboard for example, it actually adapts to target size of individual keys based on an underlying language model. So it’ll actually understand if I’m typing, “Hey, I’m going to see L.” It’ll make the E key bigger because it knows Lex is the person I’m going to go see. And so that kind of predictiveness can make the experience much more smooth, even without improvements to the underlying decoder or feature detection part of the stack.
So we do that with a feature called magnetic targets, we actually index the screen, and we understand, “Okay, these are the places that are very small targets that might be difficult to hit. Here’s the kind of cursor dynamics around that location that might be indicative of the user trying to select it. Let’s make it easier. Let’s blow up the size of it in a way that makes it easier for the user to sort of snap onto that target.” So all these little details, they matter a lot in helping the user be independent in their day-to-day living.
Neural decoder
Lex Fridman
So how much of the work on the decoder is generalizable to P2, P3, P4, P5 PM? How do you improve the decoder in a way that’s generalizable?
So how much of the work on the decoder is generalizable to P2, P3, P4, P5 PM? How do you improve the decoder in a way that’s generalizable?
Bliss Chapman
Yeah, great question. So the underlying signal we’re trying to decode is going to look very different in P2 than in P1. For example, channel number 345 is going to mean something different in user one than it will in user two, just because that electrode that corresponds with channel 345 is going to be next to a different neuron in user one to person user two. But the approach is the methods, the user experience of how do you get the right behavioral pattern from the user to associate with that neural signal. We hope that will translate over multiple generations of users.

We hope that will translate over multiple generations of users.
And beyond that, it’s very, very possible, in fact, quite likely that we’ve overfit to Noland’s user experience, desires and preferences. And so what I hope to see is that when we get a second, third, fourth participant, that we find what the right wide minimums are that cover all the cases that make it more intuitive for everyone. And hopefully, there’s a crosspollination of things, where, “Oh, we didn’t think about that with this user because they can speak. But with this user who just can fundamentally not speak at all, this user experience is not optimal.” Those improvements that we make there should hopefully translate then to even people who can speak but don’t feel comfortable doing so because we’re in a public setting, like their doctor’s office.
Lex Fridman
So the actual mechanism of open-loop labeling, and then closed-loop labeling would be the same, and hopefully can generalize across the different users-

And Webgrid is that, a nice video game that also serves as great calibration.

It’s so funny, I’ve heard this reaction so many times. Before the first user was implanted, we had an internal perception that the first user would not find this fun. And so we thought really quite a bit actually about, “Should we build other games that are more interesting for the user, so we can get this kind of data and help facilitate research that’s for long duration and stuff like this?” Turns out that people love this game. I always loved it, but I didn’t know that that was a shared perception.

I would guess it’s below 40, but above 20, somewhere in there is probably the right… That I’d never to be thinking about. It also matters how difficult the task is. You can imagine some people might be able to do 10,000 targets on the screen, and maybe they can do better that way. So there’s some task optimizations you could do to try to boost your performance as well.

Bliss Chapman
Yeah. The first answer that’s important to say is, I don’t know. This is edge of the research so, again, nobody’s gotten to that number before, so what’s next is going to be a heuristic guess from my part. What we’ve seen historically is that different parts of the stack can compile next to different time points. So when I first joined Neuralink, three years ago or so, one of the major problems was just the latency of the Bluetooth connection. The radio in the device wasn’t super good, it was an early revision of the implant. And it just, no matter how good your decoder was, if your thing is updating every 30 milliseconds or 50 milliseconds, it’s just going to be choppy. And no matter how good you are, that’s going to be frustrating and lead to challenges. So at that point, it was very clear that the main challenge is just get the data off the device in a very reliable way such that you can enable the next challenge to be tackled.

So at that point, it was very clear that the main challenge is just get the data off the device in a very reliable way such that you can enable the next challenge to be tackled.
And then at some point it was actually the modeling challenge of how do you just build a good mapping, like the supervised learning problem of, you have a bunch of data and you have a label you’re trying to predict, just what is the right neural decoder architecture and hyperparameters to optimize that? And that was the problem for a bit, and once you solve that, it became a different bottleneck. I think the next bottleneck after that was actually just software stability and reliability. If you have widely varying inference latency in your system or your app just lags out every once in a while, it decreases your ability to maintain and get in a state of flow, and it basically just disrupts your control experience. And so there’s a variety of different software bugs and improvements we made that basically increased the performance of the system, made it much more reliable, much more stable and led to a state where we could reliably collect data to build better models with.
So that was a bottleneck for a while, it was just the software stack itself. If I were to guess right now, there’s two major directions you could think about for improving VPS further. The first major direction is labeling. So labeling is, again, this fundamental challenge of given a window of time where the user is expressing some behavioral intent, what are they really trying to do at the granularity of every millisecond? And that again, is a task design problem, it’s a UX problem, it’s a machine learning problem, it’s a software problem. It touches all those different domains. The second thing you can think about to improve BPS further is either completely changing the thing you’re decoding or just extending the number of things that you’re decoding. So this is serving the direction of functionality, basically, you can imagine giving more clicks.
For example, a left click, a right click, a middle click, different actions like click-and-drag for example, and that can improve the effective bit rate of your communication processes. If you’re trying to allow the user to express themselves through any given communication channel, you can measure that with bits per second. But what actually is measured at the end of the day is how effective are they at navigating their computer? So from the perspective of the downstream tasks that you care about, functionality and extending functionality is something we’re very interested in, because not only can it improve the number of BPS, but it can also improve the downstream independence that the user has and the skill and efficiency with which they can operate their computer.
Lex Fridman
Would the number of threads increasing also potentially help?
Would the number of threads increasing also potentially help?
Bliss Chapman
Yes. Short answer is yes. It’s a bit nuanced how that manifests in the numbers. So what you’ll see is that if you plot a curve of number of channels that you’re using for decode versus either the offline metric of how good you are at decoding or the online metric of in practice how good is the user at using this device, you see roughly a log curve. So as you move further out in number of channels, you get a corresponding logarithmic improvement in control quality and offline validation metrics. The important nuance here is that each channel corresponds with a specific represented intention in the brain. So for example, if you have a channel 254, it might correspond with moving to the right. Channel 256, might mean move to the left. If you want to expand the number of functions you want to control, you really want to have a broader set of channels that covers a broader set of imagined movements. You can think of it like Mr. Potato Man actually, if you had a bunch of different imagined movements you could do, how would you map those imagined movements to input to a computer? You could imagine handwriting to output characters on the screen. You could imagine just typing with your fingers and have that output text on the screen. You could imagine different finger modulations for different clicks. You can imagine wiggling your big nose for opening some menu or wiggling your big toe to have command tab occur or something like this. So it’s really the amount of different actions you can take in the world depends on how many channels you have on the information content that they carry.

Right, so that’s more about the number of actions. So actually as you increase the number of threads, that’s more about increasing the number of actions you’re able to perform.

But one other nuance there that is worth mentioning. So again, our goal is really to enable a user with paralyzes to control the computer as fast as I can, so that’s BPS, with all the same functionality I have, which is what we just talked about, but then also as reliably as I can. And that last point is very related to channel account discussion. So as you scale out number of channels, the relative importance of any particular feature of your model input to the output control of the user diminishes, which means that if the neural non-stationarity effect is per channel, or if the noise is independent such that more channels means on average less output effect, then your reliability of your system will improve. So one core thesis that at least I have is that scaling channel account should improve the reliability system without any work on the decoder itself.

Can you linger on the reliability here? So first of all, when you say non-stationarity of the signal, which aspect are you referring to?
Can you linger on the reliability here? So first of all, when you say non-stationarity of the signal, which aspect are you referring to?
Bliss Chapman
Yeah, so maybe let’s talk briefly what the actual underlying signal looks like. So again, I spoke very briefly at the beginning about how when you imagine moving to the right or imagine moving to the left, neurons might fire more or less, and the frequency content that signal, at least in the motor cortex, it’s very correlated with the output intention, the behavioral task that the user is doing. You can imagine actually this is not obvious that rate coding, which is the name of that phenomenon, is the only way the brain could represent information. You can imagine many different ways in which the brain could encode intention, and there’s actually evidence in bats for example, that there’s temporal codes. So timing codes of exactly when particular neurons fire is the mechanism of information representation. But at least in the motor cortex, there’s substantial evidence that it’s rate coding or at least first order of effect is that it’s rate coding.

So timing codes of exactly when particular neurons fire is the mechanism of information representation. But at least in the motor cortex, there’s substantial evidence that it’s rate coding or at least first order of effect is that it’s rate coding.
So then if the brain is representing information by changing the frequency of a neuron firing, what really matters is the delta between the baseline state of the neuron and what it looks like when it’s modulated. And what we’ve observed and what has also been observed in academic work is that that baseline rate, if you’re to target the scale, if you imagine that analogy for measuring flour or something when you’re baking, that baseline state of how much the pot weighs is actually different day to day. So if what you’re trying to measure is how much rice is in the pot, you’re going to get a different measurement different days because you’re measuring with different pots. So that baseline rate shifting is really the thing that at least from a first order description of the problem is what’s causing this downstream bias. There can be other effects, not linear effects on top of that, but at least at a very first order description of the problem. That’s what we observed day to day is that the baseline firing rate of any particular neuron or observed on a particular channel is changing.
Lex Fridman
So can you just adjust to the baseline to make it relative to the baseline nonstop?
So can you just adjust to the baseline to make it relative to the baseline nonstop?
Bliss Chapman
Yeah, this is a great question. So with monkeys, we have found various ways to do this. One example way to do this is you ask them to do some behavioral tasks like play the game with a joystick, you measure what’s going on in the brain. You compute some mean of what’s going on across all the input features, and you subtract that on the input when you’re doing your BCI session, works super well. For whatever reason, that doesn’t work super well with Noland. I actually don’t know the full reason why, but I can imagine several explanations.

For whatever reason, that doesn’t work super well with Noland. I actually don’t know the full reason why, but I can imagine several explanations.
One such explanation could be that the context effect difference between some open-loop task and some closed-loop task is much more significant with Noland than it is with the monkey. Maybe in this open-loop task, he’s watching the Lex Fridman Podcast while he’s doing the task or he’s whistling and listening to music and talking with his friend and ask his mom what’s for dinner while he’s doing this task. So the exact difference in context between those two states may be much larger and thus lead to a bigger generalization gap between the features that you’re normalizing at open-loop time and what you’re trying to use at closed-loop time.
Lex Fridman
That’s interesting. Just on that point, it’s incredible to watch Noland be able to multitask, to do multiple tasks at the same time, to be able to move the mouse cursor effectively while talking and while being nervous because he’s talking in front of [inaudible 06:33:45]

Maybe one comment on that too. For folks that aren’t familiar with assistive technology, I think there’s a common belief that, well, why can’t you just use an eye tracker or something like this for helping somebody move a mouse on the screen? It’s really a fair question and one that I actually was not confident before Sir Noland that this was going to be a profoundly transformative technology for people like him. And I’m very confident now that it will be, but the reasons are subtle. It really has to do with ergonomically how it fits into their life, even if you can just offer the same level of control as what they would have with an eye tracker or with a mouse stick, but you don’t need to have that thing in your face. You don’t need to be positioned a certain way.

You don’t need your caretaker to be around to set it up for you. You can activate it when you want, how you want, wherever you want. That level of independence is so game-changing for people. It means that they can text a friend at night privately without their mom needing to be in the loop. It means that they can open up and browse the internet at 2:00 AM when nobody’s around to set their iPad up for them. This is a profoundly game-changing thing for folks in that situation, and this is even before we start talking about folks that may not be able to communicate at all or ask for help when they want to. This can be potentially the only link that they have to the outside world. And yeah, that one doesn’t, I think, need explanation of why that’s so impactful.
Lex Fridman
You mentioned NeuroDecodeR. How much machine learning is in the decoder, how much magic, how much science, how much art? How difficult is it to come up with a decoder that figures out what these sequence of spikes mean?
You mentioned NeuroDecodeR. How much machine learning is in the decoder, how much magic, how much science, how much art? How difficult is it to come up with a decoder that figures out what these sequence of spikes mean?
Bliss Chapman
Yeah, good question. There’s a couple of different ways to answer this, so maybe I’ll zoom out briefly first and then I’ll go down one of the rabbit holes. So the zoomed out view is that building the decoder is really the process of building the dataset plus compiling it into the weights, and each of those steps is important. The direction I think of further improvement is primarily going to be in the dataset side of how do you construct the optimal labels for the model. But there’s an entirely separate challenge of then how do you compile the best model? And so I’ll go briefly down the second rabbit hole. One of the main challenges with designing the optimal model for BCI is that offline metrics don’t necessarily correspond to online metrics. It’s fundamentally a control problem. The user is trying to control something on the screen and the exact user experience of how you output the intention impacts their ability to control. So for example, if you just look at validation loss as predicted by your model, there can be multiple ways to achieve the same validation loss.

The user is trying to control something on the screen and the exact user experience of how you output the intention impacts their ability to control. So for example, if you just look at validation loss as predicted by your model, there can be multiple ways to achieve the same validation loss.
Not all of them are equally controllable by the end user. And so it might be as simple as saying, oh, you could just add auxiliary loss terms that help you capture the thing that actually matters. But this is a very complex nuanced process. So how you turn the labels into the model is more of a nuanced process than just a standard supervised learning problem. One very fascinating anecdote here, we’ve tried many different neural network architectures that translate brain data to velocity outputs, for example. And one example that’s stuck in my brain from a couple of years ago now is at one point, we were using just fully-connected networks to decode the brain activity. We tried A-B test where we were measuring the relative performance in online control sessions of one deconvolution over the input signal. So if you imagine per channel you have a sliding window that’s producing some convolved feature, for each of those input sequences for every single channel simultaneously, you can actually get better validation metrics, meaning you’re fitting the data better and it’s generalizing better in offline data if you use this convolutional architecture. You’re reducing parameters. It’s a standard procedure when you’re dealing with time series data. Now it turns out that when using that model online, the controllability was worse, was far worse, even though the offline metrics were better, and there can be many ways to interpret that. But what that taught me at least was that, hey, it’s at least the case right now that if you were to just throw a bunch of compute at this problem and you were trying to hyperparameter optimize or let some GPT model hard code or come up with or invent many different solutions, if you were just optimizing for loss, it would not be sufficient, which means that there’s still some inherent modeling gap here. There’s still some artistry left to be uncovered here of how to get your model to scale with more compute, and that may be fundamentally a labeling problem, but there may be other components to this as well.
Lex Fridman
Is it data constraint at this time, which is what it sounds like? How do you get a lot of good labels?

But even just the quantity ’cause it has to be trained on the interactions. I guess there’s not that many interactions.
Bliss Chapman
Yeah, so it depends what version of this you’re talking about. So if you’re talking about, let’s say, the simplest example of just 2D velocity, then I think, yeah, data quality is the main thing. If you’re talking about how to build a multi-function output that lets you do all the inputs the computer that you and I can do, then it’s actually a much more sophisticated nuanced modeling challenge because now you need to think about not just when the users are left clicking, but when you’re building the left click model, you also need to be thinking about how to make sure it doesn’t fire when they’re trying to right click or when they’re trying to move the mouse.

So one example of an interesting bug from week one of BCI with Noland was when he moved the mouse, the click signal dropped off a cliff and when he stopped, the click signal went up. So again, there’s a contamination between the two inputs. Another good example was at one point he was trying to do a left click and drag, and the minute he started moving, the left click signal dropped off a cliff. So again, ’cause some contamination between the two signals, you need to come up with some way to either in the dataset or in the model build robustness against this kind of, you think of it like overfitting, but really it’s just that the model has not seen this kind of variability before. So you need to find some way to help the model with that.
Lex Fridman
This is super cool ’cause it feels like all of this is very solvable, but it’s hard.

Yes, it is fundamentally an engineering challenge. This is important to emphasize, and it’s also important to emphasize that it may need fundamentally new techniques, which means that people who work on let’s say unsupervised speech classification using CTC loss for example, with internal to Siri, they could potentially have very applicable skills to this.

So what things are you excited about in the future development of the software stack on Neuralink? So everything we’ve been talking about, the decoding, the UX?
So what things are you excited about in the future development of the software stack on Neuralink? So everything we’ve been talking about, the decoding, the UX?
Bliss Chapman
I think there’s something I’m excited about from the technology side and some I’m excited about for understanding how this technology is going to be best situated for entering the world, so I’ll work backwards. On the technology entering the world side of things, I’m really excited to understand how this device works for folks that cannot speak at all, that have no ability to bootstrap themselves into useful control by voice command, for example, and are extremely limited in their current capabilities. I think that will be an incredibly useful signal for us to understand really, what is an existential threat for all startups, which is product market fit. Does this device have the capacity and potential to transform people’s lives in the current state? And if not, what are the gaps? And if there are gaps, how do we solve them most efficiently?

Does this device have the capacity and potential to transform people’s lives in the current state? And if not, what are the gaps? And if there are gaps, how do we solve them most efficiently?
So that’s what I’m very excited about for the next year or so of clinical trial operations. On the technology side, I’m quite excited about basically everything we’re doing. I think it’s going to be awesome. The most prominent one I would say is scaling channel account. So right now we have a 1,000-channel device. The next version we’ll have between 3 and 6,000 channels, and I would expect that curve to continue in the future. And it’s unclear what set of problems will just disappear completely at that scale and what set of problems will remain and require for their focus. And so I’m excited about the clarity of gradient that gives us in terms of the user experiences we choose to focus our time and resources on. And then also in terms of even things as simple as non-stationarity, does that problem just completely go away at that scale? Or do we need to come up with new creative UXes still even at that point?
And also when we get to that time point, when we start expanding out dramatically the set of functions that you can output from one brain how to deal with all the nuances of both the user experience of not being able to feel the different keys under your fingertips, but still needing to be able to modulate all of them in synchrony to achieve the thing you want. And again, you don’t have that appropriate set of feedback loop, so how can you make that intuitive for a user to control a high dimensional control surface without feeling the thing physically? I think that’s going to be a super interesting problem. I’m also quite excited to understand do these scaling laws continue? As you scale channel count, how much further out do you go before that saturation point is truly hit?
And it’s not obvious today. I think we only know what’s in the interpolation space. We only know what’s between 0 and 1,024, but we don’t know what’s beyond that. And then there’s a whole range of interesting neuroscience and brain questions, which is, when you stick more stuff in the brain in more places, you get to learn much more quickly about what those brain regions represent. And so I’m excited about that fundamental neuroscience learning, which is also important for figuring out how to most efficiently insert electrodes in the future. So yeah, I think all those dimensions I’m really, really excited about. And that doesn’t even get close to touching the software stack that we work on every single day and what we’re working on right now.
Lex Fridman
Yeah, it seems virtually impossible to me that 1,000 electrodes is where it saturates. It feels like this would be one of those silly notions in the future where obviously you should have millions of electrodes and this is where the true breakthroughs happen. You tweeted, “Some thoughts are most precisely described in poetry.” Why do you think that is?

Bliss Chapman
I think it’s because the information bottleneck of language is pretty steep, and yet you’re able to reconstruct on the other person’s brain more effectively without being literal. If you can express a sentiment such that in their brain they can reconstruct the actual true underlying meaning and beauty of the thing that you’re trying to get across, the generator function in their brain is more powerful than what language can express. And so the mechanism of poetry is really just to feed or seed that generator function.

And that’s actually going to be relevant for full-on telepathy. It’s like if you just read the poetry literally, that doesn’t say much of anything interesting. It requires a human to interpret it. So it’s the combination of the human mind and all the experiences that a human being has within the context of the collective intelligence of the human species that makes that poem make sense and they load that in. So in that same way, the signal that carries from human to human meaning may seem trivial, but may actually carry a lot of power because of the complexity of the human mind and the receiving end. Yeah, that’s interesting. Who was it? I think Joscha Bach [inaudible 06:45:24] said something about all the people that think we’ve achieved AGI explain why humans like music.

Cause a lot of the tricks in both poetry and music are basically you have some repeated structure and then you do a twist. It’s like, okay, clause 1, 2, 3 is one thing and then clause four is like, “Okay, now we’re onto the next theme,” and they play with exactly when the surprise happens and the expectation of the user. And that’s even true through history as musicians evolve in music, they take some known structure that people are familiar with and they just tweak it a little bit. They tweak it and add a surprising element. This is especially true in classical music heritage, but that’s what I’m wondering. Is it all just entropy?

There’s a TV show I really like called The West Wing, and in The West Wing there’s a character, he’s the President of the United States who’s having a discussion about the Bible with one of their colleagues. And the colleague says something about the Bible says X, Y, and Z, and the President says, “Yeah, but it also says A, B, C.” The person says, “Well, do you believe the Bible to be literally true?” And the President says, “Yes, but I also think that neither of us are smart enough to understand it.” I think the analogy here for the meaning of life is that largely we don’t know the right question to ask.

So I think I’m very aligned with the Hitchhiker’s Guide to the Galaxy version of this question, which is basically, if we can ask the right questions, it’s much more likely we find the meaning of human existence. So in the short term as a heuristic in the search policy space, we should try to increase the diversity of people asking such questions or generally of consciousness and conscious beings asking such questions. So again, I think I will take the I don’t know card here, but say I do think there are meaningful things we can do that improve the likelihood of answering that question.

It’s interesting how much value you assign to the task of asking the right questions. That’s the main thing, it’s not the answers, it’s the questions.

And in that situation, it’s very obvious that what matters is, are you asking them the right question to be able to say yes or no to?

It was a freak thing that happened. Imagine you’re running into the ocean, although this is a lake, but you’re running into the ocean and you get to about waist high, and then you dive in, take the rest of the plunge under the wave or something. That’s what I did, and then I just never came back up. Not sure what happened. I did it running into the water with a couple of guys, and so my idea of what happened is really just that I took a stray fist, elbow, knee, foot, something to the side of my head. The left side of my head was sore for about a month afterwards, so I must’ve taken a pretty big knock, and then they both came up and I didn’t. And so I was face down in the water for a while. I was conscious, and then eventually just realized I couldn’t hold my breath any longer and I keep saying took a big drink.

People, I don’t know if they like that I say that. It seems like I’m making light of it all, but it’s just how I am, and I don’t know. I am a very relaxed stress-free person. I rolled with the punches for a lot of this. I took it in stride. It’s like, “All right, well, what can I do next? How can I improve my life even a little bit on a day-to-day basis?” At first, just trying to find some way to heal as much of my body as possible to try to get healed, to try to get off a ventilator, learn as much as I could so I could somehow survive once I left the hospital. And then thank God I had my family around me. If I didn’t have my parents, my siblings, then I would’ve never made it this far.
They’ve done so much for me, more than I can ever thank them for, honestly, and a lot of people don’t have that. A lot of people in my situation, their families either aren’t capable of providing for them or honestly just don’t want to, and so they get placed somewhere in some sort of home. So thankfully, I had my family. I have a great group of friends, a great group of buddies from college who have all rallied around me, and we’re all still incredibly close. People always say if you’re lucky, you’ll end up with one or two friends from high school that you keep throughout your life. I have about 10 or 12 from high school that have all stuck around, and we still get together, all of us twice a year. We call it the spring series and the fall series. This last one we all did, we dressed up X-Men, so I did a-

… Professor Xavier, and it was freaking awesome. It was so good. So yeah, I have such a great support system around me, and so being a quadriplegic isn’t that bad. I get waited on all the time. People bring me food and drinks, and I get to sit around and watch as much TV and movies and anime as I want. I get to read as much as I want. It’s great.

It’s beautiful to see that you see the silver lining in all of this. Just going back, do you remember the moment when you first realized you were paralyzed from the neck down?

Noland Arbaugh
Yep. I was face down in the water when I… whatever, something hit my head. I tried to get up and I realized I couldn’t move, and it just clicked. I’m like, “All right, I’m paralyzed, can’t move. What do I do? If I can’t get up? I can’t flip over, can’t do anything, then I’m going to drown eventually.” And I knew I couldn’t hold my breath forever, so I just held my breath and thought about it for maybe 10, 15 seconds. I’ve heard from other people that on lookers, I guess the two girls that pulled me out of the water were two of my best friends. They were lifeguards, and one of them said that it looked like my body was shaking in the water like I was trying to flip over and stuff, but I knew. I knew immediately, and I realized that that’s what my situation was from here on out.

I knew immediately, and I realized that that’s what my situation was from here on out.
Maybe if I got to the hospital, they’d be able to do something.When I was in the hospital right before surgery, I was trying to calm one of my friends down. I had brought her with me from college to camp, and she was just bawling over me, and I was like, “Hey, it’s going to be fine. Don’t worry.” I was cracking some jokes to try to lighten the mood. The nurse had called my mom, and I was like, “Don’t tell my mom. She’s just going to be stressed out. Call her after I’m out of surgery ’cause at least she’ll have some answers then, whether I live or not, really.” And I didn’t want her to be stressed through the whole thing, but I knew.
And then when I first woke up after surgery, I was super drugged up. They had me on fentanyl three ways, which was awesome. I don’t recommend it, but I saw some crazy stuff on that fentanyl, and it was still the best I’ve ever felt on drugs, medication, sorry, on medication. I remember the first time I saw my mom in the hospital, I was just bawling. I had ventilator in. I couldn’t talk or anything, and I just started crying because it was more like seeing her… The whole situation obviously was pretty rough, but it was just seeing her face for the first time was pretty hard. But yeah, I never had a moment of, “Man, I’m paralyzed. This sucks. I don’t want to be around anymore.” It was always just, “I hate that I have to do this, but sitting here and wallowing isn’t going to help.”
Lex Fridman
So immediate acceptance.

Noland Arbaugh

Has there been low points along the way?
Has there been low points along the way?
Noland Arbaugh
Yeah, yeah, sure. There are days when I don’t really feel like doing anything. Not so much anymore. Not for the last couple of years I don’t really feel that way. I’ve more so just wanted to try to do anything possible to make my life better at this point. But at the beginning, there were some ups and downs. There were some really hard things to adjust to. First off, just the first couple months, the amount of pain I was in was really, really hard. I remember screaming at the top of my lungs in the hospital because I thought my legs were on fire, and obviously I can’t feel anything, but it’s all nerve pain. And so that was a really hard night. I asked them to give me as much pain meds as possible, but they’re like, “You’ve had as much as you can have, so just deal with it. Go to a happy place,” sort of thing. So that was a pretty low point.

So that was a pretty low point.
And then every now and again, it’s hard realizing things that I wanted to do in my life that I won’t be able to do anymore. I always wanted to be a husband and father, and I just don’t think that I could do it now as a quadriplegic. Maybe it’s possible, but I’m not sure I would ever put someone I love through that, having to take care of me and stuff. Not being able to go out and play sports, I was a huge athlete growing up, so that was pretty hard. Little things too, when I realized I can’t do them anymore. There’s something really special about being able to hold a book and smell a book, the feel, the texture, the smell as you turn the pages, I just love it and I can’t do it anymore, and it’s little things like that.
The two-year mark was pretty rough. Two years is when they say you will get back basically as much as you’re ever going to get back as far as movement and sensation goes. And so for the first two years, that was the only thing on my mind was try as much as I can to move my fingers, my hands, my feet, everything possible to try to get sensation and movement back. And then when the two-year mark hit, so June 30, 2018, I was really sad that that’s where I was, and then just randomly here and there, but I was never depressed for long periods of time. Just it never seemed worthwhile to me.
Lex Fridman
What gave you strength?

Noland Arbaugh
My faith. My faith in God was a big one. My understanding that it was all for purpose, and even if that purpose wasn’t anything involving Neuralink, even if that purpose was… There’s a story in the Bible about Job, and I think it’s a really, really popular story about how Job has all of these terrible things happen to him, and he praises God throughout the whole situation. I thought, and I think a lot of people think for most of their lives that they are Job, that they’re the ones going through something terrible, and they just need to praise God through the whole thing and everything will work out.

At some point after my accident, I realized that I might not be Job, that I might be one of his children that gets killed or kidnapped or taken from him. And so it’s about terrible things that happen to those around you who you love. So maybe in this case, my mom would be Job and she has to get through something extraordinarily hard, and I just need to try and make it as best as possible for her because she’s the one that’s really going through this massive trial.
Noland Arbaugh
… she’s the one that’s really going through this massive trial and that gave me a lot of strength, and obviously my family. My family and my friends, they give me all the strength that I need on a day-to-day basis. So it makes things a lot easier having that great support system around me.

Noland Arbaugh
Yeah, yeah. I mean, I’ve just always thought I could do anything I ever wanted to do. There was never anything too big. Whatever I set my mind to, I felt like I could do it. I didn’t want to do a lot. I wanted to travel around and be sort of like a gypsy and go work odd jobs. I had this dream of traveling around Europe and being like, I don’t know, a shepherd in Wales or Ireland, and then going and being a fisherman in Italy, doing all of these things for a year. It’s such cliche things, but I just thought it would be so much fun to go and travel and do different things.

And so I’ve always just seen the best in people around me too, and I’ve always tried to be good to people. And growing up with my mom too, she’s like the most positive energetic person in the world, and we’re all just people people. I just get along great with people. I really enjoy meeting new people, and so I just wanted to do everything. This is kind of just how I’ve been.

Yeah, a bit. Also, it’s just kind of how I am. I just, like I said, I roll with the punches with everything. I always used to tell people I don’t stress about things much, and whenever I’d see people getting stressed, I would just say, “It’s not hard just don’t stress about it and that’s all you need to do. And they’re like, “That’s not how that works.” I’m like, “It works for me. Just don’t stress and everything will be fine. Everything will work out.” Obviously not everything always goes well, and it’s not like it all works out for the best all the time, but I just don’t think stress has had any place in my life since I was a kid.

First Neuralink human participant

What was the experience like of you being selected to be the first human being to have a Neuralink device implanted in your brain? Were you scared? Excited?

Noland Arbaugh
No, no. It was cool. I was never afraid of it. I had to think through a lot. Should I do this? Be the first person? I could wait until number two or three and get a better version of the Neuralink. The first one might not work. Maybe it’s actually going to kind of suck. It’s going to be the worst version ever in a person, so why would I do the first one? I’ve already kind of been selected? I could just tell them, “Okay, find someone else, and then I’ll do number two or three.” I’m sure they would let me, they’re looking for a few people anyways, but ultimately I was like, I don’t know? There’s something about being the first one to do something. It’s pretty cool. I always thought that if I had the chance that I would like to do something for the first time, this seemed like a pretty good opportunity. And I was never scared.

I always thought that if I had the chance that I would like to do something for the first time, this seemed like a pretty good opportunity. And I was never scared.
I think my faith had a huge part in that. I always felt like God was preparing me for something. I almost wish it wasn’t this, because I had many conversations with God about not wanting to do any of this as a quadriplegic. I told Him, “I’ll go out and talk to people. I’ll go out and travel the world and talk to stadiums, thousands of people, give my testimony. I’ll do all of it, but heal me first. Don’t make me do all of this in a chair. That sucks.” And I guess He won that argument. I didn’t really have much of a choice. I always felt like there was something going on. And to see how, I guess easily I made it through the interview process and how quickly everything happened, how the stars sort of aligned with all of this. It just told me as the surgery was getting closer, it just told me that it was all meant to happen.
It was all meant to be, and so I shouldn’t be afraid of anything that’s to come. And so I wasn’t. I kept telling myself like, “You say that now, but as soon as the surgery comes, you’re probably going to be freaking out. You’re about to have brain surgery.” And brain surgery is a big deal for a lot of people, but it’s an even bigger deal for me. It’s all I have left. The amount of times I’ve been like, “Thank You, God, that you didn’t take my brain and my personality and my ability to think, my love of learning, my character, everything. Thank You so much. As long as You left me that, then I think I can get by.” And I was about to let people go root around in there like, “Hey, we’re going to go put some stuff in your brain. Hopefully it works out.” And so it was something that gave me pause, but like I said, how smoothly everything went.
I never expected for a second that anything would go wrong. Plus the more people I met on the Barrow side and on the Neuralink side, they’re just the most impressive people in the world. I can’t speak enough to how much I trust these people with my life and how impressed I am with all of them. And to see the excitement on their faces, to walk into a room and, roll into a room and see all of these people looking at me like, “We’re so excited. We’ve been working so hard on this and it’s finally happening.” It’s super infectious and it just makes me want to do it even more. And to help them achieve their dreams, I don’t know, it’s so rewarding and I’m so happy for all of them, honestly.
Day of surgery

Noland Arbaugh
No, no. I thought I was going to, but as surgery approached the night before, the morning of, I was just excited. I was like, “Let’s make this happen.” I think I said that, something like that to Elon on the phone. Beforehand we were FaceTiming, and I was like, “Let’s rock and roll.” And he’s like, “Let’s do it.” I don’t know. I wasn’t scared. So we woke up. I think we had to be at the hospital at 5:30 AM. I think surgery was at 7:00 AM So we woke up pretty early. I’m not sure much of us slept that night. Got to the hospital 5:30, went through all the pre-op stuff. Everyone was super nice. Elon was supposed to be there in the morning, but something went wrong with his plane, so we ended up FaceTiming. That was cool. I had one of the greatest one-liners of my life after that phone call. Hung up with him. There were 20 people around me and I was like, “I just hope he wasn’t too starstruck talking to me.”

Noland Arbaugh
No. No, it just came to me. I was like, “This seems right.” Went into surgery. I asked if I could pray right beforehand, so I prayed over the room. I asked God if He would be with my mom in case anything happened to me and just to calm her nerves out there. Woke up, played a bit of a prank on my mom. I don’t know if you’ve heard about it?

Noland Arbaugh
… No, no, not one bit. It was something I had talked about ahead of time with my buddy Bane. I was like, “I would really like to play a prank on my mom.” Very specifically, my mom. She’s very gullible. I think she had knee surgery once even, and after she came out of knee surgery, she was super groggy. She’s like, “I can’t feel my legs.” And my dad looked at her. He was like, “You don’t have any legs. They had to amputate both your legs.” And we just do very mean things to her all the time. I’m so surprised that she still loves us.

He was like, “You don’t have any legs. They had to amputate both your legs.” And we just do very mean things to her all the time. I’m so surprised that she still loves us.
But right after surgery, I was really worried that I was going to be too groggy, not all there. I had had anesthesia once before and it messed me up. I could not function for a while afterwards. And I said a lot of things that… I was really worried that I was going to start, I don’t know, dropping some bombs and I wouldn’t even know. I wouldn’t remember. So I was like, “Please God, don’t let that happen, and please let me be there enough to do this to my mom.”
And so she walked in after surgery. It was the first time they had been able to see me after surgery, and she just looked at me. She said, “Hi, how are you? How are you doing? How do you feel?” And I looked at her and this very, I think the anesthesia helped, very groggy, sort of confused look on my face. It’s like, “Who are you?” And she just started looking around the room at the surgeons, at the doctors like, “What did you do to my son? You need to fix this right now.” Tears started streaming. I saw how much she was freaking out. I was like, “I can’t let this go on.” And so I was like, “Mom, mom, I’m fine. It’s all right.” And still, she was not happy about it. She still says she’s going to get me back someday, but I mean, I don’t know. I don’t know what that’s going to look like.

What was the first time you were able to feel that you can use the Neuralink device to affect the world around you?
What was the first time you were able to feel that you can use the Neuralink device to affect the world around you?
Noland Arbaugh
The first little taste I got of it was actually not too long after surgery. Some of the Neuralink team had brought in a little iPad, a little tablet screen, and they had put up eight different channels that were recording some of my neuron spikes and they put it in front of me. They’re like, “This is real time your brain firing.” I was like, “That’s super cool.” My first thought was, “I mean, if they’re firing now, let’s see if I can affect them in some way.”

So I started trying to wiggle my fingers and I just started scanning through the channels, and one of the things I was doing was moving my index finger up and down, and I just saw this yellow spike on top row, third box over or something. I saw this yellow spike every time I did it, and I was like, “Oh, that’s cool.” And everyone around me was just like, “What are you seeing?” I was like, “Look at this one. Look at this top row, third box over this yellow spike. That’s me right there, there, there.” And everyone was freaking out. They started clapping. I was like, “That’s super unnecessary.” This is what’s supposed to happen, right?
Lex Fridman
So you’re imagining yourself moving each individual finger one at a time, and then seeing that you can notice something. And then when you did the index finger, you’re like, “Oh, cool.”

Noland Arbaugh
Yeah, I was wiggling all of my fingers to see if anything would happen. There was a lot of other things going on, but that big yellow spike was the one that stood out to me. I’m sure that if I would’ve stared at it long enough, I could have mapped out maybe a hundred different things. But the big yellow spike was the one that I noticed.

Maybe you could speak to what it’s like to wiggle your fingers, to imagine the cognitive effort required to wiggle your index finger, for example. How easy is that to do?

Noland Arbaugh
Pretty easy for me. It’s something that at the very beginning, after my accident, they told me to try and move my body as much as possible. Even if you can’t, just keep trying because that’s going to create new neural pathways or pathways in my spinal cord to reconnect these things to hopefully regain some movement someday.

Noland Arbaugh
It’ll start reconnecting for some people, some people it never works. Some people they’ll do it. For me, I got some bicep control back, and that’s about it. If I try enough, I can wiggle some of my fingers, not on command. It’s more like if I try to move, say my right pinky, and I just keep trying to move it, after a few seconds it’ll wiggle. So I know there’s stuff there. I know, and that happens with a few different of my fingers and stuff. But yeah, that’s what they tell you to do. One of the people at the time when I was in the hospital came in and told me for one guy who had recovered most of his control, what he thought about every day was actually walking, like the act of walking just over and over again. So I tried that for years. I tried just imagining walking, which is, it’s hard. It’s hard to imagine all of the steps that go into, well, taking a step. All of the things that have to move, all of the activations that have to happen along your leg in order for one step to occur.

But you’re not just imagining, you’re doing it, right?
Noland Arbaugh
I’m trying. Yeah. So it’s imagining over again what I had to do to take a step, because it’s not something any of us think about. We just, you want to walk and you take a step. You don’t think about all of the different things that are going on in your body. So I had to recreate that in my head as much as I could, and then I practice it over, and over, and over again.

So it’s not like a third person perspective, it’s a first person perspective. It’s not like you’re imagining yourself walking. You’re literally doing everything, all the same stuff as if you’re walking.

It was both. There’s a scene in one of the Kill Bill movies, actually, oddly enough, where she is paralyzed, I don’t know, from a drug that was in her system. And then she finds some way to get into the back of a truck or something, and she stares at her toe and she says, “Move,” like move your big toe. And after a few seconds on screen, she does it. And she did that with every one of her body parts until she can move again. I did that for years, just stared at my body and said, “Move your index finger, move your big toe.” Sometimes vocalizing it out loud, sometimes just thinking it. I tried every different way to do this to try to get some movement back. And it’s hard because it actually is taxing, physically taxing on my body, which is something I would’ve never expected.

It’s not like I’m moving, but it feels like there’s a buildup of, the only way I can describe it is there are signals that aren’t getting through from my brain down, because there’s that gap in my spinal cord, so brain down, and then from my hand back up to the brain. And so it feels like those signals get stuck in whatever body part that I’m trying to move, and they just build up, and build up, and build up until they burst. And then once they burst, I get this really weird sensation of everything dissipating back out to level, and then I do it again.
It’s also just a fatigue thing, like a muscle fatigue, but without actually moving your muscles. It’s very, very bizarre. And then if you try to stare at a body part or think about a body part and move for two, three, four, sometimes eight hours, it’s very taxing on your mind. It takes a lot of focus. It was a lot easier at the beginning because I wasn’t able to control a TV in my room or anything. I wasn’t able to control any of my environment. So for the first few years, a lot of what I was doing was staring at walls. And so, obviously I did a lot of thinking and I tried to move a lot just over, and over, and over again.

But yeah, I was talking about how a lot of what they’ve had me do, especially at the beginning, well, I still do it now, is body mapping. So there will be a visualization of a hand or an arm on the screen, and I have to do that motion, and that’s how they train the algorithm to understand what I’m trying to do. And so it made things very seamless for me I think.

Yeah. Yeah. I don’t know if other quadriplegics, other paralyzed people give up. I hope they don’t. I hope they keep trying, because I’ve heard other paralyzed people say, “Don’t ever stop.” They tell you two years, but you just never know. The human body’s capable of amazing things. So I’ve heard other people say, “Don’t give up.” I think one girl had spoken to me through some family members and said that she had been paralyzed for 18 years, and she’d been trying to wiggle her index finger for all that time, and she finally got it back 18 years later. So I know that it’s possible, and I’ll never give up doing it. I do it when I’m lying down watching TV. I’ll find myself doing it just almost on its own. It’s just something I’ve gotten so used to doing that I don’t know. I don’t think I’ll ever stop.

Which honestly was something that I think Neuralink gave me that I can’t thank them enough for. I can’t show my appreciation for it enough, was being able to visually see that what I’m doing is actually having some effect. It’s a huge part of the reason why I know now that I’m going to keep doing it forever. Because before Neuralink, I was doing it every day and I was just assuming that things were happening. It’s not like I knew. I wasn’t getting back any mobility or sensation or anything. So I could have been running up against a brick wall for all I knew. And with Neuralink, I get to see all the signals happening real time, and I get to see that what I’m doing can actually be mapped. When we started doing click calibrations and stuff, when I go to click my index finger for a left click, that it actually recognizes that. It changed how I think about what’s possible with retraining my body to move. And so yeah, I’ll never give up now.

And also just the signal that there’s still a powerhouse of a brain there that’s like, and as the technology develops, that brain is, I mean, that’s the most important thing about the human body is the brain, and it can do a lot of the control. So what did it feel like when you first could wiggle the index finger and saw the environment respond? That little thing, whatever [inaudible 07:22:49] just being way too dramatic according to you?

Noland Arbaugh
Yeah, it was very cool. I mean, it was cool, but I keep telling this to people. It made sense to me. It made sense that there are signals still happening in my brain, and that as long as you had something near it that could measure those, that could record those, then you should be able to visualize it in some way. See it happen. And so that was not very surprising to me. I was just like, “Oh, cool. We found one, we found something that works.”

It was cool to see that their technology worked and that everything that they had worked so hard for was going to pay off. But I hadn’t moved a cursor or anything at that point. I hadn’t interacted with a computer or anything at that point. So it just made sense. It was cool. I didn’t really know much about BCI at that point either, so I didn’t know what sort of step this was actually making. I didn’t know if this was a huge deal, or if this was just like, “Okay, this is, it’s cool that we got this far, but we’re actually hoping for something much better down the road.” It’s like, “Okay.” I just thought that they knew that it turned on. So I was like, “Cool, this is cool.”
Lex Fridman
Well, did you read up on the specs of the hardware you get installed, the number of threads, all this kind of stuff.

When was the first time you were able to move a mouse cursor?
When was the first time you were able to move a mouse cursor?
Noland Arbaugh
I know it must have been within the first maybe week, a week or two weeks that I was able to first move the cursor. And again, it kind of made sense to me. It didn’t seem like that big of a deal. It was like, okay, well, how do I explain this? When everyone around you starts clapping for something that you’ve done, it’s easy to say, “Okay, I did something cool.”

It was like, okay, well, how do I explain this? When everyone around you starts clapping for something that you’ve done, it’s easy to say, “Okay, I did something cool.”
That was impressive in some way. What exactly that meant, what it was hadn’t really set in for me. So again, I knew that me trying to move a body part and then that being mapped in some sort of machine learning algorithm to be able to identify my brain signals and then take that and give me cursor control, that all kind of made sense to me. I don’t know all the ins and outs of it, but I was like, “There are still signals in my brain firing. They just can’t get through because there’s a gap in my spinal cord, and so they can’t get all the way down and back up, but they’re still there.” So when I moved the cursor for the first time, I was like, “That’s cool, but I expected that that should happen.” It made sense to me. When I moved the cursor for the first time with just my mind, without physically trying to move. So I guess I can get into that just a little bit. The difference between attempted movement, and imagine movement.
Lex Fridman
Yeah, that’s a fascinating difference [inaudible 07:26:18] from one to the other.
Yeah, that’s a fascinating difference [inaudible 07:26:18] from one to the other.
Noland Arbaugh
Yeah, yeah, yeah. So attempted movement is me physically trying to attempt to move, say my hand. I try to attempt to move my hand to the right, to the left, forward and back. And that’s all attempted. Attempt to lift my finger up and down, attempt to kick or something. I’m physically trying to do all of those things, even if you can’t see it. This would be me attempting to shrug my shoulders or something. That’s all attempted movement. That’s what I was doing for the first couple of weeks when they were going to give me cursor control. When I was doing body mapping, it was attempt to do this, attempt to do that. When Nir was telling me to imagine doing it, it kind of made sense to me, but it’s not something that people practice. If you started school as a child and they said, “Okay, write your name with this pencil,” and so you do that. Like, “Okay, now imagine writing your name with that pencil.”

If you started school as a child and they said, “Okay, write your name with this pencil,” and so you do that. Like, “Okay, now imagine writing your name with that pencil.”
Kids would think, “Uh, I guess that kind of makes sense,” and they would do it. But that’s not something we’re taught, it’s all how to do things physically. We think about thought experiments and things, but that’s not a physical action of doing things. It’s more what you would do in certain situations. So imagine movement, it never really connected with me. I guess you could maybe describe it as a professional athlete swinging a baseball bat or swinging a golf club. Imagine what you’re supposed to do. But then you go right to that and physically do it. Then you get a bat in your hand, and then you do what you’ve been imagining.
And so I don’t have that connection. So telling me to imagine something versus attempting it, there wasn’t a lot that I could do there mentally. I just kind of had to accept what was going on and try. But the attempted moving thing, it all made sense to me. If I try to move, then there’s a signal being sent in my brain, and as long as they can pick that up, then they should be able to map it to what I’m trying to do. And so when I first moved the cursor like that, it was just like, “Yes, this should happen. I’m not surprised by that.”
Lex Fridman
But can you clarify, is there supposed to be a difference between imagine movement and attempted movement?
But can you clarify, is there supposed to be a difference between imagine movement and attempted movement?

Remember there was one Tuesday we were messing around and I think, I forget what swear word you used, but there’s a swear word that came out of your mouth when you figured out you could just do the direct cursor control.
Remember there was one Tuesday we were messing around and I think, I forget what swear word you used, but there’s a swear word that came out of your mouth when you figured out you could just do the direct cursor control.
Noland Arbaugh
Yeah, it blew my mind, no pun intended. Blew my mind when I first moved the cursor just with my thoughts and not attempting to move. It’s something that I found over the couple of weeks building up to that, that as I get better cursor controls, the model gets better, then it gets easier for me to… I don’t have to attempt as much to move it. And part of that is something that I’d even talked with them about when I was watching the signals of my brain one day. I was watching when I attempted to move to the right and I watched the screen as I saw the spikes. I was seeing the spike, the signal was being sent before I was actually attempting to move. I imagine just because when you go to say, move your hand or any body part, that signal gets sent before you’re actually moving, has to make it all the way down and back up before you actually do any sort of movement.

I imagine just because when you go to say, move your hand or any body part, that signal gets sent before you’re actually moving, has to make it all the way down and back up before you actually do any sort of movement.
So there’s a delay there. And I noticed that there was something going on in my brain before I was actually attempting to move that my brain was anticipating what I wanted to do, and that all started sort of, I don’t know, percolating in my brain. It was just there always in the back like, “That’s so weird that it could do that. It kind of makes sense, but I wonder what that means as far as using the Neuralink.”
And then as I was playing around with the attempted movement and playing around with the cursor, and I saw that as the cursor control got better, that it was anticipating my movements and what I wanted it to do, like cursor movements, what I wanted it to do a bit better and a bit better. And then one day I just randomly, as I was playing Webgrid, I looked at a target before I had started attempting to move, I was just trying to get over, train my eyes to start looking ahead, like, “Okay, this is the target I’m on, but if I look over here to this target, I know I can maybe be a bit quicker getting there.”
And I looked over and the cursor just shot over. It was wild. I had to take a step back. I was like, “This should not be happening.” All day I was just smiling. I was so giddy. I was like, “Guys, do you know that this works? I can just think it and it happens.” Which they’d all been saying this entire time like, “I can’t believe you’re doing all this with your mind.” I’m like, “Yeah, but is it really with my mind. I’m attempting to move and it’s just picking that up so it doesn’t feel like it’s with my mind.” But when I moved it for the first time like that, it was, oh man. It made me think that this technology, that what I’m doing is actually way, way more impressive than I ever thought. It was way cooler than I ever thought, and it just opened up a whole new world of possibilities of what could possibly happen with this technology and what I might be able to be capable of with it.

That’s what it felt like. I felt like I had discovered something, but for me, maybe not necessarily for the world-at-large or this field-at-large, it just felt like an aha moment for me. Like, “Oh, this works.” Obviously it works. And so that’s what I do all the time now. I kind of intermix the attempted movement and imagine movement. I do it all together because I’ve found that…

Noland Arbaugh
I do it all together because I’ve found that there is some interplay with it that maximizes efficiency with the cursor. So it’s not all one or the other. It’s not all just, I only use attempted or I only use imagined movements. It’s more I use them in parallel and I can do one or the other. I can just completely think about whatever I’m doing, but I don’t know, I like to play around with it. I also like to just experiment with these things. Every now and again, I’ll get this idea in my head, I wonder if this works and I’ll just start doing it, and then afterwards I’ll tell them, “By the way, I wasn’t doing that like you guys wanted me to. I thought of something and I wanted to try it and so I did. It seems like it works, so maybe we should explore that a little bit.”
I do it all together because I’ve found that there is some interplay with it that maximizes efficiency with the cursor. So it’s not all one or the other.

So I think that discovery’s not just for you, at least from my perspective. That’s a discovery for everyone else who ever uses a Neuralink that this is possible. I don’t think that’s an obvious thing that this is even possible. It’s like I was saying to Bliss earlier, it’s like the four-minute mile. People thought it was impossible to run a mile in four minutes and once the first person did it, then everyone just started doing it. So just to show that it’s possible, that paves the way to anyone can now do it. That’s the thing that’s actually possible. You don’t need to do the attempted movement, you can just go direct.

For people who don’t know, can you explain how the Link app works? You have an amazing stream on the topic. Your first stream, I think, on X describing, the app. Can you just describe how it works?

Noland Arbaugh
Yeah, so it’s just an app that Neuralink created to help me interact with the computer. So on the Link app there are a few different settings, and different modes, and things I can do on it. So there’s the body mapping, which we kind of touched on. There’s a calibration. Calibration is how I actually get cursor control, so calibrating what’s going on in my brain to translate that into cursor control. So it will pop out models. What they use, I think, is time. So it would be five minutes and calibration will give me so good of a model, and then if I’m in it for 10 minutes and 15 minutes, the models will progressively get better. And so the longer I’m in it, generally, the better the models will get.

That’s really cool because you often refer to the models. So the model’s the thing that’s constructed once you go through the calibration step.

And then you also talked about sometimes you’ll play a really difficult game like Snake just to see how good the model is.
And then you also talked about sometimes you’ll play a really difficult game like Snake just to see how good the model is.
Noland Arbaugh
Yeah. Yeah, so Snake is kind of like my litmus test for models. If I can control a snake decently well then I know I have a pretty good model. So yeah, the Link app has all of those. It has Webgrid in it now. It’s also how I connect to the computer just in general. So they’ve given me a lot of voice controls with it at this point. So I can say, “Connect,” or, “Implant disconnect,” and as long as I have that charger handy, then I can connect to it. So the charger is also how I connect to the Link app to connect to the computer. I have to have the implant charger over my head when I want to connect, to have it wake up, because the implant’s in hibernation mode always when I’m not using it. I think there’s a setting to wake it up every so long, so we could set it to half an hour, or five hours, or something, if I just want it to wake up periodically.

So yeah, I’ll connect to the Link app and then go through all sorts of things, calibration for the day, maybe body mapping. I made them give me a little homework tab because I am very forgetful and I forget to do things a lot. So I have a lot of data collection things that they want me to do.
Lex Fridman
Is the body mapping part of the data collection or is that also part of the calibration?

Yeah, I’ve been a terrible first candidate for how much I’ve been slacking on my homework. But yeah, it’s just something that they want me to do every day to track how well the Neuralink is performing over time and to have something to give, I imagine, to give to the FDA to create all sorts of fancy charts and stuff, and show like, hey, this is what the Neuralink… This is how it’s performing day one, versus day 90, versus day 180, and things like that.

It’s a bubble game. So there will be yellow bubbles that pop up on the screen. At first, it is open loop. So open loop, this is something that I still don’t fully understand, the open loop and closed loop thing.

Open loop is basically I have no control over the cursor. The cursor will be moving on its own across the screen and I am following, by intention, the cursor to different bubbles. And then the algorithm is training off of what the signals it’s getting are as I’m doing this. There are a couple of different ways that they’ve done it. They call it center-out targets. So there will be a bubble in the middle and then eight bubbles around that, and the cursor will go from the middle to one side. So say, middle to left, back to middle, to up, to middle, up, right, and they’ll do that all the way around the circle. And I will follow that cursor the whole time, and then it will train off of my intentions, what it is expecting my intentions to be throughout the whole process.

Yeah, so generally for calibration, I’m doing attempted movements because I think it works better. I think the better models, as I progress through calibration, make it easier to use imagined movements.

Wait. Wait, wait, wait. So calibrated on attempted movement will create a model that makes it really effective for you to then use the force.

Noland Arbaugh
Yes. I’ve tried doing calibration with imagined movement and it just doesn’t work as well for some reason. So that was the center-out targets. There’s also one where a random target will pop up on the screen and it’s the same. I just move, I follow along wherever the cursor is, to that target all across the screen. I’ve tried those with imagined movement and for some reason the models just don’t, they don’t give as high level as quality when we get into closed loop. I haven’t played around with it a ton, so maybe the different ways that we’re doing calibration now might make it a bit better. But what I’ve found is there will be a point in calibration where I can use imagined movement. Before that point, it doesn’t really work.

But what I’ve found is there will be a point in calibration where I can use imagined movement. Before that point, it doesn’t really work.
So if I do calibration for 45 minutes, the first 15 minutes, I can’t use imagined movement. It just doesn’t work for some reason. And after a certain point, I can just feel it, I can tell. It moves different. That’s the best way I can describe it. It’s almost as if it is anticipating what I am going to do again, before I go to do it. And so using attempted movement for 15 minutes, at some point, I can tell when I move my eyes to the next target that the cursor is starting to pick up. It’s starting to understand, it’s learning what I’m going to do.
Lex Fridman
So first of all, it’s really cool that, you are a true pioneer in all of this. You’re exploring how to do every aspect of this most effectively and there’s just, I imagine, so many lessons learned from this. So thank you for being a pioneer in all these kinds of different super technical ways. And it’s also cool to hear that there’s a different feeling to the experience when it’s calibrated in different ways because I imagine your brain is doing something different and that’s why there’s a different feeling to it. And then trying to find the words and the measurements to those feelings would be also interesting. But at the end of the day, you can also measure your actual performance, on whether it’s Snake or Webgrid, you could see what actually works well. And you’re saying, for the open loop calibration, the attempted movement works best for now.

Noland Arbaugh
No, no, it makes sense to me. We’ve done it with a cursor and without a cursor in open loop. So sometimes it’s just, say for the center out, you’ll start calibration with a bubble lighting up and I push towards that bubble, and then when it’s pushed towards that bubble for, say, three seconds, a bubble will pop and then I come back to the middle. So I’m doing it all just by my intentions. That’s what it’s learning anyway. So it makes sense that as long as I follow what they want me to do, follow the yellow brick road, that it’ll all work out.

Yeah, they always feel so bad making me do calibration like, oh, we’re about to do a 40-minute calibration. I’m like, “All right, do you guys want to do two of them?” I’m always asking to… Whatever they need, I’m more than happy to do. And it’s not bad. I get to lie there or sit in my chair and do these things with some great people. I get to have great conversations. I can give them feedback. I can talk about all sorts of things. I could throw something on, on my TV in the background, and split my attention between them. It’s not bad at all. I don’t mind it.

Noland Arbaugh
Yeah, that’s one thing that I really, really enjoy about Webgrid is because I’m so competitive. The higher the BPS, the higher the score, I know the better I’m doing, and so if I… I think I’ve asked at one point, one of the guys, if he could give me some sort of numerical feedback for calibration. I would like to know what they’re looking at. Like, oh, we see this number while you’re doing calibration, and that means, at least on our end, that we think calibration is going well. And I would love that because I would like to know if what I’m doing is going well or not. But then they’ve also told me, yeah, not necessarily one to one. It doesn’t actually mean that calibration is going well in some ways. So it’s not like a hundred percent and they don’t want to skew what I’m experiencing or want me to change things based on that, if that number isn’t always accurate to how the model will turn out or the end result,. That’s at least what I got from it.

That’s at least what I got from it.
One thing I have asked them, and something that I really enjoy striving for, is towards the end of calibration, there is a time between targets. And so I like to keep, at the end, that number as low as possible. So at the beginning it can be four or five, six seconds between me popping bubbles, but towards the end I like to keep it below 1.5 or if I could get it to one second between bubbles. Because in my mind, that translates really nicely to something like Webgrid, where I know if I can hit a target, one every second, that I’m doing real, real well.
Lex Fridman
There you go. That’s a way to get a score on the calibrations, like the speed. How quickly can you get from bubble to bubble?

They just say there is a loop and at one point it’s open and I can’t control, and then I get control and it’s closed. So I’m finishing the loop.

So how long the calibration usually take? You said 10, 15 minutes, [inaudible 07:48:52]-
Noland Arbaugh
Well, yeah, they’re trying to get that number down pretty low. That’s what we’ve been working on a lot recently, is getting that down is low as possible. So that way, if this is something that people need to do on a daily basis or if some people need to do on a every-other-day basis or once a week, they don’t want people to be sitting in calibration for long periods of time. I think they’ve wanted to get it down seven minutes or below, at least where we’re at right now. It’d be nice if you never had to do calibration. So we’ll get there at some point, I’m sure, the more we learn about the brain, and I think that’s the dream. I think right now, for me to get really, really good models, I’m in calibration 40 or 45 minutes. And I don’t mind, like I said, they always feel really bad, but if it’s going to get me a model that can break these records on Webgrid, I’ll stay in it for flipping two hours.

Yeah, it’s literally just a grid. They can make it as big or small as you can make a grid. A single box on that grid will light up and you go and click it. And it is a way for them to benchmark how good a BCI is. So it’s pretty straightforward. You just click targets.

Yep. So I like playing on bigger grids because the bigger the grid, the more BPS, it’s bits per second, that you get every time you click one. So I’ll say I’ll play on a 35 by 35 grid, and then one of those little squares, a cell, you can call it, target, whatever, will light up. And you move the cursor there, and you click it, and then you do that forever.

Yeah. Yeah, I’m at 8.5 right now. I would’ve beaten that literally the day before I came to Austin. But I had a, I don’t know, a five-second lag right at the end, and I just had to wait until the latency calmed down, and then I kept clicking. But I was at 8.01, and then five seconds of lag, and then the next three targets I clicked all stayed at 8.01. So if I would’ve been able to click during that time of lag, I probably would’ve hit, I don’t know, I might’ve hit nine. So I’m there. I’m really close, and then this whole Austin trip has really gotten in the way of my Webgrid playing ability.
Yeah. Yeah, I’m at 8.5 right now. I would’ve beaten that literally the day before I came to Austin. But I had a, I don’t know, a five-second lag right at the end, and I just had to wait until the latency calmed down, and then I kept clicking. But I was at 8.01, and then five seconds of lag, and then the next three targets I clicked all stayed at 8.01. So if I would’ve been able to click during that time of lag, I probably would’ve hit, I don’t know, I might’ve hit nine. So I’m there. I’m really close, and then this whole Austin trip has really gotten in the way of my Webgrid playing ability.

In a fundamental way, it’s really inspiring and what you’re doing is inspiring in that way because it’s not just about the game. Everything you’re doing there has impact. By striving to do well on Webgrid, you’re helping everybody figure out how to create the system all along the decoding, the software, the hardware, the calibration, all of it. How to make all of that work so you can do everything else really well.

0.3 seconds, which sucks. It really slows down how high I’m able to get. I still hit 50, I think I hit 50-something net trials per minute in that, which was pretty good because I’m able to… One of the settings is also how slow you need to be moving in order to initiate a click, to start a click. So I can tell, sort of, when I’m on that threshold, to start initiating a click just a bit early. So I’m not fully stopped over the target when I go to click, I’m doing it on my way to the targets a little, to try to time it just right.

Yeah, and I’ve played with that a little bit too. I have to adjust a ton of different parameters in order to play with 0.1, and I don’t have control over all of that on my end yet. It also changes how the models are trained. If I train a model, like in Webgrid, I bootstrap on a model, which basically is them training models as I’m playing Webgrid based off of the Webgrid data that I’m… So if I play Webgrid for 10 minutes, they can train off that data specifically in order to get me a better model. If I do that with 0.3 versus 0.1, the models come out different. The way that they interact, it’s just much, much different. So I have to be really careful. I found that doing it with 0.3 is actually better in some ways. Unless I can do it with 0.1 and change all of the different parameters, then that’s more ideal, because obviously 0.3 is faster than 0.1. So I could get there. I can get there.

Noland Arbaugh
For right now, it’s the hover clicking with the dwell cursor. Before all the thread retraction stuff happened, we were calibrating clicks, left click, right click. That was my previous ceiling, before I broke the record again with the dwell cursor, was I think on a 35 by 35 grid with left and right click. And you get more BPS, more bits per second, using multiple clicks because it’s more difficult.

Retracted threads

Exactly. Exactly. So what did it feel like with the retractions, that some of the threads are retracted?
Noland Arbaugh
It sucked. It was really, really hard. The day they told me was the day of my big Neuralink tour at their Fremont facility. They told me right before we went over there. It was really hard to hear. My initial reaction was, all right, go in, fix it. Go in, take it out and fix it. The first surgery was so easy. I went to sleep, a couple hours later I woke up and here we are. I didn’t feel any pain, didn’t take any pain pills or anything. So I just knew that if they wanted to, they could go in and put in a new one next day if that’s what it took because I wanted it to be better and I wanted not to lose the capability. I had so much fun playing with it for a few weeks, for a month. It had opened up so many doors for me. It had opened up so many more possibilities that I didn’t want to lose it after a month.

I had so much fun playing with it for a few weeks, for a month. It had opened up so many doors for me. It had opened up so many more possibilities that I didn’t want to lose it after a month.
I thought it would’ve been a cruel twist of fate if I had gotten to see the view from the top of this mountain and then have it all come crashing down after a month. And I knew, I say the top of the mountain, but how I saw it was I was just now starting to climb the mountain and there was so much more that I knew was possible. And so to have all of that be taken away was really, really hard. But then on the drive over to the facility, I don’t know, five minute drive, whatever it is, I talked with my parents about it. I prayed about it. I was just like, I’m not going to let this ruin my day. I’m not going to let this ruin this amazing tour that they have set up for me. I want to go show everyone how much I appreciate all the work they’re doing.
I want to go meet all of the people who have made this possible, and I want to go have one of the best days of my life, and I did. And it was amazing, and it absolutely was one of the best days I’ve ever been privileged to experience. And then for a few days I was pretty down in the dumps, but for the first few days afterwards, I didn’t know if it was ever going to work again. And then I made the decision that, even if I lost the ability to use the Neuralink, even if I lost out on everything to come, if I could keep giving them data in any way, then I would do that.
If I needed to just do some of the data collection every day or body mapping every day for a year, then I would do it because I know that everything I’m doing helps everyone to come after me, and that’s all I wanted. Just the whole reason that I did this was to help people, and I knew that anything I could do to help, I would continue to do, even if I never got to use the cursor again, then I was just happy to be a part of it. And everything that I had done was just a perk. It was something that I got to experience, and I know how amazing it’s going to be for everyone to come after me. So might as well just keep trucking along.
Lex Fridman
Well, that said, you were able to get to work your way up, to get the performance back. So this is like going from Rocky I to Rocky II. So when did you first realize that this is possible, and what gave you the strength, the motivation, the determination to do it, to increase back up and beat your previous record?

Mm-hmm.

Noland Arbaugh
So when they did that, it was like a light over the head, light bulb moment, like, oh, this works and this seems like we can run with this. And I saw the uptick in performance immediately. I could feel it when they switched over. I was like, “This is better. This is good. Everything up until this point,” for the last few weeks, last, whatever, three or four weeks because it was before they even told me, “Everything before this sucked. Let’s keep doing what we’re doing now.” And at that point it was not like, oh, I know I’m still only at, say in Webgrid terms, four or five BPS compared to my 7.5 before, but I know that if we keep doing this, then I can get back there. And then they gave me the dwell cursor and the dwell cursor sucked at first. It’s obviously not what I want, but it gave me a path forward to be able to continue using it and hopefully to continue to help out. And so I just ran with it, never looked back. Like I said, I’m just kind of person, I roll with the punches anyway. So-

What was the process? What was the feedback loop on the figuring out how to do the spike detection in a way that would actually work well for Noland?
What was the process? What was the feedback loop on the figuring out how to do the spike detection in a way that would actually work well for Noland?
Bliss Chapman
Yeah, it’s a great question. So maybe just to describe first how the actual update worked. It was basically an update to your implant. So we just did an over-the-air software update to his implants, same way you’d update your Tesla or your iPhone. And that firmware change enabled us to record averages of populations of neurons nearby individual electrodes. So we have less resolution about which individual neuron is doing what, but we have a broader picture of what’s going on nearby an electrode overall. And that feedback loop, basically as Noland described it, it was immediate when we flipped that switch. I think the first day we did that, you had three or four BPS right out of the box, and that was a light bulb moment for, okay, this is the right path to go down. And from there, there’s a lot of feedback around how to make this useful for independent use.

And from there, there’s a lot of feedback around how to make this useful for independent use.
So what we care about ultimately is that you can use it independently to do whatever you want. And to get to that point, it required us to re-engineer the UX, as you talked about with the dwell cursor, to make it something that you can use independently without us needing to be involved all the time. And yeah, this is obviously the start of this journey still. Hopefully we get back to the places where you’re doing multiple clicks and using that to control, much more fluidly, everything, and much more naturally the applications that you’re trying to interface with.

I was trying to keep the cursor from clicking and I was just doing it while I was trying to go to sleep. And I was like, “Okay, this is a problem.” [inaudible 08:05:52].

It’s a lot of me just using it day in and day out and saying, “Hey, can you guys do this for me? Give me this. I want to be able to do that. I need this.” I think a lot of it just doesn’t occur to them maybe, until someone is actually using the app, using the implant. It’s just something that they just never would’ve thought of or it’s very specific to even me, maybe what I want. It’s something I’m a little worried about with the next people that come is maybe they will want things much different than how I’ve set it up or what the advice I’ve given the team, and they’re going to look at some of the things they’ve added for me. [inaudible 08:07:26] like, “That’s a dumb idea.

And then they’re also going to give me some pushback about, yeah, what you are asking them to do here, that’s a bad idea. Let’s do it this way. And I’m more than happy to have that happen, but it’s just a lot of different interactions with different games or applications, the internet, just with the computer in general. There’s tons of bugs that end up popping up, left, right, center.
So it’s just me trying to use it as much as possible and showing them what works and what doesn’t work, and what I would like to be better. And then they take that feedback and they usually create amazing things for me. They solve these problems in ways I would’ve never imagined. They’re so good at everything they do, and so I’m just really thankful that I’m able to give them feedback and they can make something of it, because a lot of my feedback is really dumb. It’s just like, “I want this, please do something about it,” and it’ll come back, super well-thought-out, and it’s way better than anything I could have ever thought of or implemented myself. So they’re just great. They’re really, really cool.

As the BCI community grows, would you like to hang out with the other folks with Neuralinks? What relationship, if any, would you want to have with them? Because you said they might have a different set of ideas of how to use the thing.

I hope, day one, they wipe the floor with me. I hope they beat it and they crush it, double it if they can, just because on one hand it’s only going to push me to be better because I’m super competitive. I want other people to push me. I think that is important for anyone trying to achieve greatness is they need other people around them who are going to push them to be better. And I even made a joke about it on X once, once the next people get chosen, cue buddy cop music. I’m just excited to have other people to do this with and to share experiences with. I’m more than happy to interact with them as much as they want, more than happy to give them advice. I don’t know what kind of advice I could give them, but if they have-

That they should have fun with this, because it is a lot of fun, and that I hope they work really, really hard because it’s not just for us, it’s for everyone that comes after us. And come to me if they need anything. And to go to Neuralink if they need anything. Man, Neuralink moves mountains. They do absolutely anything for me that they can, and it’s an amazing support system to have. It puts my mind at ease for so many things that I have had questions about or so many things I want to do, and they’re always there, and that’s really, really nice. And so I would tell them not to be afraid to go to Neuralink with any questions that they have, any concerns, anything that they’re looking to do with this. And any help that Neuralink is capable of providing, I know they will. And I don’t know. I don’t know. Just work your ass off because it’s really important that we try to give our all to this.

Now you’re a real pro athlete. Just keep it short. Maybe it’s good to talk about what you’ve been able to do now that you have a Neurolink implant, the freedom you gain from this way of interacting with the outside world.

Noland Arbaugh
Yeah. It’s what all… I don’t know, people in my position want. They just want more independence. The more load that I can take away from people around me, the better. If I’m able to interact with the world without using my family, without going through any of my friends, needing them to help me with things, the better. If I’m able to sit up on my computer all night and not need someone to sit me up, say, on my iPad, in a position where I can use it, and then have to have them wait up for me all night until I’m ready to be done using it, it takes a load off of all of us and it’s really all I can ask for. It’s something that I could never thank Neuralink enough for, and I know my family feels the same way. Just being able to have the freedom to do things on my own at any hour of the day or night, it means the world to me and… I don’t know.

When you’re up at 2:00 AM playing Webgrid by yourself, I just imagine it’s darkness and there’s just a light glowing and you’re just focused. What’s going through your mind? Or you were in a state of flow where it’s like the mind is empty like those Zen masters.

Noland Arbaugh
Yeah. Generally, it is me playing music of some sort. I have a massive playlist, and so I’m just rocking out to music. And then it’s also just a race against time, because I’m constantly looking at how much battery percentage I have left on my implant, like, “All right. I have 30%, which equates to X amount of time, which means I have to break this record in the next hour and a half or else it’s not happening tonight.” And so it’s a little stressful when that happens. When it’s above 50%, I’m like, “Okay, I got time.” It starts getting down to 30, and then 20 it’s like, “All right, 10%, a little popup is going to pop up right here, and it’s going to really screw my Webgrid flow. It’s going to tell me that… The low battery popup comes up and I’m like, “It’s really going to screw me over. So if I’m going to break this record, I have to do it in the next 30 seconds,” or else that popup is going to get in the way, cover my Webgrid.

And then after that, I go click on it, go back into Webgrid, and I’m like, “All right, that means I have 10 minutes left before this thing’s dead.” That’s what’s going on in my head, generally. That and whatever song’s playing. And I want to break those records so bad. It’s all I want when I’m playing Webgrid. It has become less of like, “Oh, this is just a leisurely activity. I just enjoy doing this because it just feels so nice and it puts me at ease.” It is, “No. Once I’m in Webgrid, you better break this record or you’re going to waste five hours of your life right now.” And I don’t know. It’s just fun. It’s fun, man.

Noland Arbaugh
I do. Yeah. So the great part about Korea is they focus on science tech victories, which was not planned. I’ve been playing Korea for years, and then all of the [inaudible 08:16:23] stuff happened, so it aligns. But what I’ve noticed with tech victories is if you can just rush tech, rush science, then you can do anything. At one point in the game, you’ll be so far ahead of everyone technologically that you’ll have musket men, infantrymen, planes sometimes, and people will still be fighting with bows and arrows. And so if you want to win a domination victory, you just get to a certain point with the science, and then go and wipe out the rest of the world. Or you can just take science all the way and win that way, and you’re going to be so far ahead of everyone because you’re producing so much science that it’s not even close. I’ve accidentally won in different ways just by focusing on science.

Noland Arbaugh
Yeah. I was playing only science, obviously. Just science all the way, just tech. And I was trying to get every tech in the tech tree and stuff, and then I accidentally won through a diplomatic victory, and I was so mad. I was so mad because it just ends the game one turn. It was like, “Oh, you won. You’re so diplomatic.” I’m like, “I don’t want to do this. I should have declared war on more people or something.” It was terrible. But you don’t need giant civilizations with tech, especially with Korea. You can keep it pretty small. So I generally just get to a certain military unit and put them all around my border to keep everyone out, and then I will just build up. So very isolationist.

An Optimus robot would be pretty cool. That would be sick if I could control an Optimus robot. The Link app itself, it seems like we are getting pretty dialed in to what it might look like down the road. It seems like we’ve gotten through a lot of what I want from it, at least. The only other thing I would say is more control over all the parameters that I can tweak with my cursor and stuff.

Yeah, yeah, yeah. So there’s a virtual keyboard. That’s another thing I would like to work more on is finding some way to type or text in a different way. Right now, it is a dictation basically and a virtual keyboard that I can use with the cursor, but we’ve played around with finger spelling, sign language finger spelling, and that seems really promising. So I have this thought in my head that it’s going to be a very similar learning curve that I had with the cursor where I went from attempted movement to imagine movement at one point. I have a feeling, this is just my intuition, that at some point, I’m going to be doing finger spelling and I won’t need to actually attempt to finger spell anymore, that I’ll just be able to think the letter that I want and it’ll pop up.

Noland Arbaugh
And then going from letters to words is another step. Right now, it’s finger spelling of just the sign language alphabet, but if it’s able to pick that up, then it should be able to pick up the whole sign language language, and so then if I could do something along those lines, or just the sign language spelled word, if I can spell it at a reasonable speed and it can pick that up, then I would just be able to think that through and it would do the same thing. After what I saw with the cursor control, I don’t see why it wouldn’t work, but we’d have to play around with it more.

Noland Arbaugh
Yeah, there’s a lot that’s very, very cool about this. I mean, we’re talking about the brain, so this is just motor cortex stuff. There’s so much more that can be done. The vision one is fascinating to me. I think that is going to be very, very cool. To give someone the ability to see for the first time in their life would just be… I mean, it might be more amazing than even helping someone like me. That just sounds incredible. The speech thing is really interesting. Being able to have some real-time translation and cut away that language barrier would be really cool. Any actual impairments that it could solve with speech would be very, very cool.

Future Neuralink capabilities
And then also, there are a lot of different disabilities that all originate in the brain, and you would be able to hopefully be able to solve a lot of those. I know there’s already stuff to help people with seizures that can be implanted in the brain. I imagine the same thing. And so you could do something like that. I know that even someone like Joe Rogan has talked about the possibilities with being able to stimulate the brain in different ways. I’m not sure how ethical a lot of that would be. That’s beyond me, honestly. But I know that there is a lot that can be done when we’re talking about the brain and being able to go in and physically make changes to help people or to improve their lives. So I’m really looking forward to everything that comes from this. And I don’t think it’s all that far off. I think a lot of this can be implemented within my lifetime, assuming that I live a long life.

Yeah, flip a switch like that, make someone happy. I think Joe has talked about it more in terms of you want to experience what a drug trip feels like. You want to experience what it’d be like to be on mushrooms or something like that, DMT. You can just flip that switch in the brain. My buddy, Bain, has talked about being able to wipe parts of your memory and re-experience things for the first time, like your favorite movie or your favorite book, just wipe that out real quick, and then re-fall in love with Harry Potter or something. I told him, I was like, “I don’t know how I feel about people being able to just wipe parts of your memory. That seems a little sketchy to me.” He’s like, “They’re already doing it.”

I told him, I was like, “I don’t know how I feel about people being able to just wipe parts of your memory. That seems a little sketchy to me.” He’s like, “They’re already doing it.”
Lex Fridman
Sounds legit. I would love memory replay. Just actually high resolution, replay of old memories.

Noland Arbaugh
Yeah. I saw an episode of Black Mirror about that once, so I don’t think I want it.
Yeah. I saw an episode of Black Mirror about that once, so I don’t think I want it.
Lex Fridman
Yeah, so Black Mirror always considers the worst case, which is important. I think people don’t consider the best case or the average case enough. I don’t know what it is about us humans. We want to think about the worst possible thing. We love drama. It’s like how is this new technology going to kill everybody? We just love that. Again like, “Yes, let’s watch.”

Hopefully people don’t think about that too much with me. It’ll ruin a lot of my plans.

Lex Fridman
Yeah, I assume you’re going to have to take over the world. I mean, I love your Twitter. You tweeted, “I’d like to make jokes about hearing voices in my head since getting the Neuralink, but I feel like people would take it the wrong way. Plus the voices in my head told me not to.”

Controlling Optimus robot
Lex Fridman
Please never stop. So you were talking about Optimus. Is that something you would love to be able to do to control the robotic arm or the entirety of Optimus?
Please never stop. So you were talking about Optimus. Is that something you would love to be able to do to control the robotic arm or the entirety of Optimus?
Noland Arbaugh
Oh, yeah, for sure. For sure. Absolutely.
Oh, yeah, for sure. For sure. Absolutely.
Lex Fridman
You think there’s something fundamentally different about just being able to physically interact with the world?
You think there’s something fundamentally different about just being able to physically interact with the world?
Noland Arbaugh
Yeah. Oh, 100%. I know another thing with being able to give people the ability to feel sensation and stuff too, by going in with the brain and having a Neuralink maybe do that, that could be something that could be transferred through the Optimus as well. There’s all sorts of really cool interplay between that. And then also, like you said, just physically interacting. I mean, 99% of the things that I can’t do myself, obviously, I need a caretaker for, someone to physically do things for me. If an Optimus robot could do that, I could live an incredibly independent life and not be such a burden on those around me, and it would change the way people like me live, at least until whatever this is gets cured.

If an Optimus robot could do that, I could live an incredibly independent life and not be such a burden on those around me, and it would change the way people like me live, at least until whatever this is gets cured.
But being able to interact with the world physically, that would just be amazing. And not just for having it be a caretaker or something, but something like I talked about. Just being able to read a book. Imagine an Optimus robot just being able to hold a book open in front of me. I get that smell again. I might not be able to feel it at that point, or maybe I could, again, with the sensation and stuff. But there’s something different about reading a physical book than staring at a screen or listening to an audiobook. I actually don’t like audiobooks. I’ve listened to a ton of them at this point, but I don’t really like them. I would much rather read a physical copy.
Lex Fridman
So one of the things you would love to be able to experience is opening the book, bringing it up to you, and to feel the touch of the paper.
So one of the things you would love to be able to experience is opening the book, bringing it up to you, and to feel the touch of the paper.
Noland Arbaugh
Yeah. Oh, man. The touch, the smell. I mean, it’s just something about the words on the page. And they’ve replicated that page color on the Kindle and stuff. Yeah, it’s just not the same. Yeah. So just something as simple as that.

So one of the things you miss is touch?
So one of the things you miss is touch?
Noland Arbaugh
I do. Yeah. A lot of things that I interact with in the world, like clothes or literally any physical thing that I interact within the world, a lot of times what people around me will do is they’ll just come rub it on my face. They’ll lay something on me so I can feel the weight. They will rub a shirt on me so I can feel fabric. There’s something very profound about touch, and it’s something that I miss a lot and something I would love to do again. We’ll see.

What would be the first thing you do with a hand that can touch? Give your mom a hug after that, right?
What would be the first thing you do with a hand that can touch? Give your mom a hug after that, right?
Noland Arbaugh
Yeah. I know. It’s one thing that I’ve asked God for basically every day since my accident was just being able to one day move, even if it was only my hand, so that way, I could squeeze my mom’s hand or something just to show her how much I care and how much I love her and everything. Something along those lines. Being able to just interact with the people around me. Handshake, give someone a hug. I don’t know. Anything like that. Being able to help me eat. I’d probably get really fat, which would be a terrible, terrible thing.

Noland Arbaugh
Yeah. Yeah. I mean, there were just so many upsides. And any way to find some way to feel like I’m bringing Bliss down to my level because he’s just such an amazing guy, and everything about him is just so above and beyond, that anything I can do to take him down a notch, I’m more than happy-
Yeah. Yeah. I mean, there were just so many upsides. And any way to find some way to feel like I’m bringing Bliss down to my level because he’s just such an amazing guy, and everything about him is just so above and beyond, that anything I can do to take him down a notch, I’m more than happy-

Yeah. Yeah, humble him a bit. He needs it.

God
Lex Fridman
Okay. As he’s sitting next to me. Did you ever make sense of why God puts good people through such hardship?
Okay. As he’s sitting next to me. Did you ever make sense of why God puts good people through such hardship?
Noland Arbaugh
Oh, man. I think it’s all about understanding how much we need God. And I don’t think that there’s any light without the dark. I think that if all of us were happy all the time, there would be no reason to turn to God ever. I feel like there would be no concept of good or bad, and I think that as much of the darkness and the evil that’s in the world, it makes us all appreciate the good and the things we have so much more. And I think when I had my accident, one of the first things I said to one of my best friends was… And this was within the first month or two after my accident, I said, “Everything about this accident has just made me understand and believe that God is real and that there really is a God, basically. And that my interactions with him have all been real and worthwhile.”

And that my interactions with him have all been real and worthwhile.”
And he said, if anything, seeing me go through this accident, he believes that there isn’t a God. And it’s a very different reaction, but I believe that it is a way for God to test us, to build our character, to send us through trials and tribulations, to make sure that we understand how precious He is and the things that He’s given us and the time that He’s given us, and then to hopefully grow from all of that. I think that’s a huge part of being here, is to not just have an easy life and do everything that’s easy, but to step out of our comfort zones and really challenge ourselves because I think that’s how we grow.
Hope
Lex Fridman
What gives you hope about this whole thing we have going on human civilization?
What gives you hope about this whole thing we have going on human civilization?
Noland Arbaugh
Oh, man. I think people are my biggest inspiration. Even just being at Neuralink for a few months, looking people in the eyes and hearing their motivations for why they’re doing this, it’s so inspiring. And I know that they could be other places, at cushier jobs, working somewhere else, doing X, Y, or Z, that doesn’t really mean that much. But instead, they’re here and they want to better humanity, and they want to better just the people around them. The people that they’ve interacted with in their life, they want to make better lives for their own family members who might have disabilities, or they look at someone like me and they say, “I can do something about that. So I’m going to.” And it’s always been what I’ve connected with most in the world are people.

I’ve always been a people person and I love learning about people, and I love learning how people developed and where they came from, and to see how much people are willing to do for someone like me when they don’t have to, and they’re going out of their way to make my life better. It gives me a lot of hope for just humanity in general, how much we care and how much we’re capable of when we all get together and try to make a difference. And I know there’s a lot of bad out there in the world, but there always has been and there always will be. And I think that that is… It shows human resiliency and it shows what we’re able to endure and how much we just want to be there and help each other, and how much satisfaction we get from that, because I think that’s one of the reasons that we’re here is just to help each other, and… I don’t know. That always gives me hope, is just realizing that there are people out there who still care and who want to help.

Thanks for listening to this conversation with Nolan Arbaugh, and before that, with Elon Musk, DJ Seo, Matthew McDougall, and Bliss Chapman. To support this podcast, please check out our sponsors in the description. And now, let me leave you with some words from Aldous Huxley in The Doors of Perception. “We live together. We act on and react to one another. But always, and in all circumstances, we are by ourselves. The martyrs go hand in hand into the arena. They are crucified alone. Embrace the lovers desperately tried to fuse their insulated ecstasies into a single self-transcendence in vain. But it’s very nature, every embodied spirit is doomed to suffer and enjoy its solitude, sensations, feelings, insights, fancies, all these are private, and except through symbols and a secondhand incommunicable. We can pool information about experiences, but never the experiences themselves. From family to nation, every human group is a society of island universes.” Thank you for listening and hope to see you next time.

And lifting in objects feels good. It feels good to train like a lazy bear and just lift heavy objects. But I’ve also started training with lighter weights and higher repetitions and for three month cycles, and it gives your joints a rest. Yeah, so I think it also is interesting to see how training differently changes your cognition. That’s probably hormone related, hormones downstream of training heavy versus hormones downstream of training a little bit lighter. I think my cognition is better when I’m doing more cardio and when the repetition ranges are a little bit or higher, which is not to say that people who lift heavy are dumb, but there is a… Because there’s real value in lifting heavy.
So I’ve been playing around with walking recently for two hours and thinking because I know a lot of smart people throughout history, I have walked and thought, and you have to play with things that have worked for others, not just to exercise, but to integrate this very light kind of prolonged exercise into a productive life. So they do all their thinking while they walk. It’s like a meditative type of walking, and it’s really interesting. It really works.
And he walks in, voice dictates his papers. And now with Rev or these other, maybe there are better ones than Rev, where you can convert audio files into text very quickly and then edit from there. So I will often voice dictate first drafts and things like that. And I totally agree on the long runs, the walks, the integrating that with cognitive work, harder to do with sprints and then the gym. You weight train?
And then two or three bad experiences later, I’m able to say, “Ah, every single time there was a signal from the body informing my mind, this is not good.” Now the reverse has also been true that there’ve been a number of instances in which I feel there sort of immediate delight, and there’s this almost astonishingly simple experience of feeling comfortable with somebody or at peace with something or delighted at an experience. And it turns out literally all of those experiences and people turned out to be experiences and people that are still in my life and that I still delight in every day. In other words, what’s great about getting older is that you stop questioning the signals that come from, I think deeper recesses of your nervous system to say, “Hey, this is not good,” or, “Hey, this is great, more of this.” Whereas I think in my teens, my twenties, my thirties, I’m almost 48, I’ll be 48 next month.
I didn’t trust, I didn’t listen. I actually put a lot of work into overriding those signals and learning to fight through them, thinking that somehow that was making me tougher or somehow that was making me smarter. When in fact, in the end, those people that you meet that are difficult or there are other names for it, like in the end, you’re like, “That person’s a piece of shit,” or, “This person is amazing and they’re really wonderful.” And I felt that from the go.
So some of my friends early on gave me some bad ideas, but most of the time my bad ideas came from overriding the signals that I knew that my body, and I would say my body and brain were telling me to obey, and I say body and brain is that there’s this brain region, the insula, which does many things, but it represents our sense of internal sensation and interoception. And I was talking to Paul Conte about this, who as you know, I respect tremendously. I think he’s one of the smartest people I’ve ever met. I think for different reasons. He and Marc Andreessen are some of the smartest people I’ve ever met. But Paul’s level of insight into the human psyche is absolutely astounding. And he says the opposite of what most people say about the brain, which is most people say, “Oh, the supercomputer of the brain is the forebrain.”
It’s like a monkey brain with a extra real estate put on there. And the forebrain is what makes us human and gives us our superpowers. Paul has said, and he’s done a whole series on mental health that’s coming out from our podcast in September, so this is not an attempt to plug that, but he’ll elaborate on [inaudible 00:13:08].
This is self-exploration that is rooted in psychiatry, it’s rooted in neuroscience, and I don’t think this information exists anywhere else. I’m not aware that it exists anywhere else. And he essentially distills it all down to one eight and a half by 11 sheet, which we provide for people. And he says there, I don’t want to give too much away because I would detract from what he does so beautifully, but if I tried and I wouldn’t have accomplish it anyway.
But he said, and I believe that the subconscious is the supercomputer of the brain. All the stuff working underneath our conscious awareness that’s driving our feelings and what we think are the decisions that we’ve thought through so carefully. And that only by exploring the subconscious and understanding it a little bit, can we actually improve ourselves over time and I agree. I think that so the mistake is to think that thinking can override it all. It’s a certain style of introspection and thinking that allows us to read the signals from our body, read the signals from our brain, integrate the knowledge that we’re collecting about ourselves, and to use all that in ways that are really adaptive and generative for us.
I’m somebody who’s drawn to goodness and to light and to joy and all those things like anybody else. But I think maybe it was part of how I grew up. Maybe it was the crowd I was with, but then again, even when I started spending more time with academics and scientists, I mean you see shadows in other ways, right? You see pure ambition with no passion. I recall a colleague in San Diego who it was very clear to me did not actually care about understanding the brain, but understanding the brain was just his avenue to exercise ambition. And if you gave him something else to work on, he’d work on that.
In fact, he did. He left and he worked on something else, and I realized he has no passion for understanding the brain like I assumed all scientists do, certainly why I went into it. But some people, it’s just raw ambition. It’s about winning. It doesn’t even matter what they win, which to me is crazy. But I think that’s a shadow that some people explore, not one I’ve explored. I think the shadow parts of us are very important to come to understand and look better to understand them and know that they’re there and work with them than to not acknowledge their presence and have them surface in the form of addictions or behaviors that damage us in other people.
But with no disrespect to psychiatrists, there are some excellent psychiatrists out there. There are also a lot of terrible psychiatrists out there because unless all of their patients commit suicide or half commit suicide, they can treat for a long time without it becoming visible that they’re not so good at their craft. Now, he’s superb at his craft, and I think he would say that yes, exploring some shadows, but also just understanding the self, really understanding like, “Who am I? And what’s important? What are my ambitions? What are my strivings?” Again, I’m lifting from some of the things that he’ll describe exactly how to do this. People do not spend enough time addressing those questions, and as a consequence, they discover what resides in their subconscious through the sometimes bad, hopefully also good, but manifestations of their actions.
We are driven by this huge 90% of our real estate that is not visible to our conscious awareness. And we need to understand that. I’ve talked about this before. I’ve done therapy twice a week since I was a kid. I had to as a condition of being let back in school. I found a way to either through insurance or even when I didn’t have insurance, I took an extra job writing for Thrasher Magazine when I was a postdoc so I could pay for therapy at a discount because I didn’t make much money as a postdoc.
I mean, I think for me, it’s as important as going to the gym and people think it’s just ruminating on problems, or getting… No, no, no. If you work with somebody really good, they’re forcing you to ask questions about who you really are, what you really want. It’s not just about support, but there should be support. There should be rapport, but then it’s also, there should be insight, right? Most people who get therapy, they’re getting support, there’s rapport, but insight is not easy to arrive at, and a really good psychologist or psychiatrist can help you arrive at deep insights that transform your entire life.
I oscillate between being really grateful and really self-critical. But then you have to figure out what is it? Maybe there’s a deeper root thing. Maybe there’s an insecurity in there somewhere that has to do with childhood and then you’re trying to prove something to somebody from your childhood, this kind of thing.
I don’t think we can rewire our deep preferences and what we find despicable or joyful. I do think that it’s really a question of what allows us peace. Can you be at peace with the fact that you’re very self-critical? And enjoy that, get some distance from it, have a sense of humor about it, or is it driving you in a way that’s keeping you awake at night and forcing you back to the table to do work in a way that feels self-flagellating and doesn’t feel good?
Can you get that humility and awareness of your one’s flaws? And I think that that can create, this word space sounds very new, edgy, like get space from it. You can have a sense of humor about how neurotic we can all be. I mean, neurotic isn’t actually a bad term in the classic sense of the psychologists and psychiatrists, the freudians. So that the best case is to be neurotic, to actually see one’s own issues and work with them. Whereas psychotic is the other way to be, which is obviously not good. So I think the question whether or not to work on something or to just accept it as part of ourselves, I think really depends if we feel like it’s holding us back or not. And I think you’re asking perhaps the most profound question about being a human, which is what do you do with your body? What do you do with your mind?
I mean, it’s also a question. We started off talking about fitness a little bit just for whatever reason. Do I need to run an ultra marathon? I don’t feel like I need to. David Goggins does and does a whole lot more than that. So that for him, that’s important. For me, it’s not important to do that. I don’t think he does it just so he can run the ultras. There’s clearly something else in there for him. And guys like Cam Hanes and tremendous respect for what they do and how they do it. Does one need to make their body more muscular, stronger, more endurance, more flexibility? Do you need to read harder books? I think doing hard things feels good. I know it feels good. I know that the worst I feel, the worst way to feel is when I’m procrastinating and I don’t do something.
And then whenever I do something and I complete it and I break through that point where it was hard and then I’m doing it at the end, I actually feel like I was infused with some sort of super chemical. And who knows if it’s probably a cocktail of endogenously made chemicals. But I think it is good to do hard things, but you have to be careful not to destroy your body, your mind in the process. And I think it’s about whether or not you can achieve peace. Can you sleep well at night?
Stress isn’t bad if you can sleep well at night, you can be stressed all day, go, go, go, go, go, go, go. And it’ll optimize your focus. But can you fall asleep and stay deeply asleep at night? Being in a hard relationship. Some people say that’s not good. Other people like can you be at peace in that? And I think we all have different RPM. We all kind of idle at different RPM and some people are big mellow Costello and others need more friction in order to feel at peace. But I think ultimately what we want is to feel at peace.
And then my graduate advisor, who I was working for at that time, who I loved and adored, was really like a mother to me. I knew her when she was pregnant with her two kids, died at 50, breast cancer. And then my postdoc advisor, first day of work at Stanford as a faculty member sitting across the table like this from him, had a heart attack right in front of me, died of pancreatic cancer at the end of 2017. And I remember just thinking, going back to that song there over and over and where people would… Yeah, I haven’t had many betrayals in life. I’ve had a few. But just thinking or seeing something or learning something about something, you just say you can’t believe it. And I mentioned that lyric off, that first song, Indestructible on that album because it’s just the raw emotion of like, “I can’t believe this. What I just saw is so disturbing, but I have to just keep going forward.”
There are certain things that we really do need to push not just into our periphery, but off into the gutter and keep going. And that’s a hard thing to learn how to do. But if you’re going to be functional in life, you have to. And actually just to get at this issue of do I change or do I embrace this aspect of self? About six months, it was April of this last year, I did some intense work around some things that were really challenging to me. And I did it alone, and it may have involved some medicine, and I expected to get peace through this. I was like, “I’m going to let go of it.” And I spent 11 hours just getting more and more frustrated and angry about this thing that I was trying to resolve.
And I was so unbelievably disappointed that I couldn’t get that relief. And I was like, “What is this? This is not how this is supposed to work. I’m supposed to feel peace. The clouds are supposed to lift.” And so a week went by and then another half week went by, and then someone whose opinion I trust very much. I explained this to them because I was getting a little concerned like, “What’s going on? This is worse, not better.” And they said, ” This is very simple. You have a giant blind spot, which is your sense of justice, Andrew, and your sense of anger are linked like an iron rod and you need to relax it.” And as they said that, I felt the anger dissipate. And so there was something that I think it is true. I have a very strong sense of justice and my sense of anger then at least was very strongly linked to it.
So it’s great to have a sense of justice, right? I hate to see people wrong. I absolutely do. And I’m human. I’m sure I’ve wronged people in my life. I know I have. They’ve told me, I’ve tried to apologize and reconcile where possible. Still have a lot of work to do. But where I see injustice, it draws in my sense of anger in a way that I think is just eating me up. But it was only in hearing that link that I wasn’t aware of before. It was in my subconscious, obviously. Did I feel the relaxation? There’s no amount of plant medicine or MDMA or any kind of chemical you can take that’s naturally just going to dissipate what’s hard for oneself if one embraces that or if one chooses to do it through just talk therapy or journaling or friends or introspection or all of the above. There needs to be an awareness of the things that we’re just not aware of.
So I think the answer to your question, do you embrace or do you fight these aspects of self is? I think you get in your subconscious through good work with somebody skilled. And sometimes that involves the tools I just mentioned in various combinations and you figure it out. You figure out if it’s serving you. Obviously it was not bringing me peace. My sense of justice was undermining my sense of peace. And so in understanding this link… Now, I would say, in understanding this link between justice and anger, now I think it’s a little bit more of you know, it’s not like a Twizzler stick bendy, but at least it’s not like an iron rod. When I see somebody wronged, I mean it used to just… Like immediately.
So this is this historic place that sheds so much blood, so much fear, so much anticipation of battle, all of this. So he loves this kind of spectacle and also, the meme of it, the hilarious absurdity of it. The two tech CEOs are battling it out on sand in a place where gladiators fought to the death and then bears and lions ate prisoners as part of the execution process.
I got hit. I hit some guys and definitely got hit back. I’d spar on Wednesday nights when I lived on San Diego. And when you spar with somebody, even if they hurt you, especially if they hurt you, you see that person afterwards and there’s an intimacy, right? It was in that book, Fighter’s Heart, where he explains, you’re exchanging bodily fluids with a stranger and you’re in your primitive mind and so there’s an intimacy there that persists so-
Go to graduate school, I’m working for somebody, and decide that working in her laboratory wasn’t quite right for me. So I’m literally sneaking into the laboratory next door and working for the woman next door because I liked the relationships that she had to a certain set of questions and she was a quirky person. So drawn to drama but drawn to… I like characters. I like people that have texture. And I’m not drawn to raw ambition, I’m drawn to people that seem to have a real passion for what they do and a uniqueness to them that I… Not kind of, I’ll just say how it is. I can feel their heart for what they do and I’m drawn to that and that can be good.
It’s the same reason I went to work for Ben Barris as a post-doc. It wasn’t because he was the first transgender member of the National Academy of Sciences, that was just a feature of who he was. I loved how he loved glial. He would talk about these cells like they were the most enchanting things that he’d ever seen in his life. And I was like, “This is the biggest nerd I’ve ever met and I love him.” I think I’m drawn to that.
This is another thing that Conti elaborates on quite a bit more in the series on mental health coming out. But there are different drives within us, there are aggressive drives. Not always for fighting but for intense interaction. I mean, look at Twitter. Look at some of the… People clearly have an aggressive drive. There’s also a pleasure drive. Some people also have a strong pleasure drive. They want to experience pleasure through food, through sex, through friendship, through adventure. But I think the Shakespearean drama is the drama of the different drives in different ratios in different people.
I know somebody and she’s incredibly kind. Has an extremely high pleasure drive, loves taking great care of herself and people around her through food and through retreats and through all these things and makes spaces beautiful everywhere she goes. And gifts these things that are just so unbelievably feminine and incredible. These gifts to people and then kind and thoughtful about what they like. And then.. But I would say, very little aggressive drive from my read.
And then, I know other people who just have a ton of aggressive drive and very little pressure drive and I think… So there’s this alchemy that exists where people have these things in different ratios. And then, you blend in the differences in the chromosomes and differences in hormones and differences in personal history and what you end up with is a species that creates incredible recipes of drama but also peace, also relief from drama, contentment.
I mean, I realize this isn’t the exact topic of the question. But someone I know very dearly, actually an ex-girlfriend of mine, long- term partner of mine, sent me something recently and I think it hit the nail on the head. Which is that ideally for a man, they eventually settle where they find and feel peace, where they feel peaceful, where they can be themselves and feel peaceful. Now, I’m sure there’s an equivalent or mirror image of that for women but this particular post that she sent was about men and I totally agree.
And so, it isn’t always that we’re seeking friction. But for periods of our life, we seek friction, drama, adventure, excitement, fights, and doing hard, hard things. And then I think at some point, I’m certainly coming to this point now where it’s like, “Yeah. That’s all great and checked a lot of boxes.” But I had a lot of close calls, flew really close to the sun on a lot of things with life and limb and heart and spirit and some people close to us didn’t make it. And sometimes, not making it means the career they wanted went off a cliff or their health went off a cliff or their life went off a cliff. But I think that there’s also the Shakespearean drama of the characters that exit the play and are living their lives happily in the backdrop. It just doesn’t make for as much entertainment.
I say the first one, “I’m an animal,” because I have to remember that I have a body that needs care like any of us. I need sleep, I need food, I need hydration, I need… That I’m human, that the brain of a human is marvelously complex but also marvelously self-defeating at times. And so, I’m thinking about these things in the context of the different roles. And the whole thing takes about four or five minutes and I just find it brings me a certain amount of clarity that then allows me to ratchet into the day.
The prayer piece, I think I’ve been reluctant to talk about until now because I don’t believe in pushing religion on people. And I think that… And I’m not, it’s a highly individual thing and I do believe that one can be an atheist and still pray or agnostic and still pray. But for me, it really came about through understanding that there are certain aspects of myself that I just couldn’t resolve on my own. And no matter how much therapy, no matter how much… And I haven’t done a lot of it. But no matter how much plant medicine or other forms of medicine or exercise or podcasting or science or friendship or any of that, I was just not going to resolve.
And so, I started this because a male friend said, “Prayer is powerful,” and I said, “Well, how?” And he said, “I don’t know how but it can allow you to get outside yourself. Let you give up control and at the same time, take control.” I don’t even like saying take control. But the whole notion is that… And again, forgive me, but there’s no other way to say it. The whole notion is that God works through us. Whatever God is to you, he, him, her, life force, nature, whatever it is to you, that it works through us.
And so, I do a prayer. I’ll just describe it where I make an ask to help remove my character defects. I pray to God to help remove my character defects so that I can show up better in all the roles of my life and do good work which for me is learning and teaching. And so you might say, “Well, how is that different than a meditation?” Well, I’m acknowledging that there is something bigger than me, bigger than nature as I understand it, that I cannot understand or control nor do I want to, and I’m just giving over to that. And does that make me less of a scientist? I sure as hell hope not. I certainly know… There’s the head of our neurosciences at Stanford until recently. You should talk to him directly about it. Bill Newsome has talked about his religious life.
For me, it’s really a way of getting outside myself and then understanding how I fit into this bigger picture. And the character defects part is real, right? I’m a human. I have defects. I got a lot of flaws in me like anybody and trying to acknowledge them and asking for help in removing them. Not magically but through right action, through my right action. So I do that every morning.
And I have to say that it’s helped. It’s helped a lot. It’s helped me be better to myself, be better to other people. I still make mistakes but it’s becoming a bigger part of my life. And I never thought I’d talk like this but I think it’s clear to me that if we don’t believe in something… Again, it doesn’t have to be traditional, standardized religion, but if we don’t believe in something bigger than ourselves, we, at some level, will self-destruct. I really think so.
And it’s powerful in a way that all the other stuff, meditation and all the tools, is not because it’s really operating at a much deeper and bigger level. Yeah. I think that’s all I can talk about it. Mostly because I’m still working out. The scientists in me wants to understand how it works and I want to understand. And the point is to just go, for lack of a better language for it, “There’s a higher power than me and what I can control. I’m giving up control on certain things.” And somehow, that restores a sense of agency for right action and better action.
But when things weren’t right, I couldn’t make sense of them, I would secretly pray. But I felt ashamed of that for whatever reason. And then, it was once in college, I distinctly remember I was having a hard time with a number of things and I took a run down to SAN Speech. It was at UC Santa Barbara. And I remember I was like, “I don’t know if I even have the right to do this but I’m just praying,” and I just prayed for the ability to be as brutally honest with myself and with other people as I possibly could be about a particular situation I was in at that time.
I mean, I think now it’s probably safe to say I’d gone off to college because of a high school girlfriend. Essentially, she was my family. Frankly, more than my biological family was at a certain stage of life and we’d reached a point where we were diverging and it was incredibly painful. It was like losing everything I had. And it was like, “What do I do? How do I manage this?” I was ready to quit and join the fire service just to support us so that we could move forward and it was just…
But praying, just saying, “I can’t figure this out on my own.” It’s like, “I can’t figure this out on my own,” and how frustrating that no number of friends could tell me and inner wisdom couldn’t tell me. And eventually, it led me to the right answers. She and I are friendly friends to this day. She’s happily married with a child and we’re on good terms. But I think it’s a scary thing but it’s the best thing when you just, “I can’t control all of this.” And asking for help, I think is also the piece. You’re not asking for some magic hand to come down and take care of it but you’re asking for the help to come through you so that your body is used to do these right works, right action.
And when my body would break down or I’d get sick a lot, I don’t get sick much anymore. Occasionally, about once every 18 months to two years, I’ll get something. But I used to break my foot skateboarding all the time, I couldn’t understand. What’s wrong with my body? I’m getting injured. I can’t do what everyone else can. Now, I developed more slowly. I had a long arc of puberty so that was part of it. I was still developing.
But how to get your body stronger, how to build endurance, no one told me. The information wasn’t there. So a lot of what I put out there is the information that I wish I had. Because once I had it, I was like, “Wow.” A, this stuff really works. B, it’s grounded in something real. Sometimes, certain protocols are a combination of animal and human studies, sometimes clinical trials. Sometimes there’s some mechanistic conjecture for some, not all, I always make clear which. But in the end, figuring out how things work so that we can be happier, healthier, more productive, suffer less, reduce the suffering of the world. And I think that… Well, I’ll just say thank you for asking about the prayer piece. Again, I’m not pushing or even encouraging it on anyone. I’ve just found it to be tremendously useful for me.
And I think that as we grow older, we learn to cover that stuff up. We wear masks and we have to, to be functional. I don’t think we all want to go around just being completely raw. But as you said, as you get older, you get to this point where you go, “Eh. What are we really trying to protect anyway?”
I mean, I have this theory that certainly my experience has taught me that a lot of people but I’ll talk about men because that’s what I know best, whether or not they show up strong or not, that they’re really afraid of being weak. They’re just afraid… Sometimes, the strength is even a way to try and not be weak which is different than being strong for its own sake. I’m not just talking about physical strength. I’m talking about intellectual strength. I’m talking about money. I’m talking about expressing drive. I’ve been watching this series a little bit of Chimp Empire.
So now, they start using that prefrontal cortex to do some interesting things. So in primate world, if a male is friendly with another male, wants to affiliate with him and say, “Hey, I’m backing you,” they’ll go over and they’ll pick off the little parasites and eat them. And so, the grooming is extremely important. In fact, if they want to ostracize or kill one of the members of their troop, they will just leave it alone. No one will groom it. And then, there’s actually a really disturbing sequence in that show of then the parasites start to eat away on their skin. They get infections. They have issues. No one will mate with them. They have other issues as well and can potentially die.
So the interesting thing is Number 2 and 3 start to line up a strategy to groom this guy but they are actually thinking about overtaking the entire troop setting in a new alpha. But the current alpha did that to get where he is so he knows that they’re doing this grooming thing, but they might not be sincere about the grooming. So what does he do? He takes the whole troop on a raid to another troop and sees who will fight for him and who won’t.
This is advanced contracting of behavior for a species that normally we don’t think of as sophisticated as us. So it’s very interesting and it gets to something that I hope we’ll have an opportunity to talk about because it’s something that I’m obsessed with lately, is this notion of overt versus covert contracts, right? There are overt contracts where you exchange work for money or you exchange any number of things in an overt way. But then, there are covert contracts, and those take on a very different form and always lead to, in my belief, bad things.
But now, okay. So overt contract would be we both want to do some work together, we’re going to make some money, you get X percentage, I get X percentage. It’s overt. Covert contract which is, in my opinion, always bad, would be we’re going to do some work together, you’re going to get a percentage of money, I’m going to get a percentage of money. Could look just like the overt contract but secretly, I’m resentful that I got the percentage that I got. So what I start doing is covertly taking something else. What do I take? Maybe I take the opportunity to jab you verbally every once in a while. Maybe I take the opportunity to show up late. Maybe I take the opportunity to get to know one of your coworkers so that I might start a business with them. That’s covert contracting.
And you see this sometimes in romantic relationships. One person, we won’t set the male or female in any direction here and just say it’s, “I’ll make you feel powerful if you make me feel desired.” Okay. Great. There’s nothing explicitly wrong about that contract if they both know and they both agree. But what if it’s, “I’ll do that but I’ll have kids with you so you feel powerful. You’ll have kids with me so I feel desired. But secretly, I don’t want to do that,” or one person says, “I don’t want to do that,” or both don’t. So what they end up doing is saying, “Okay. So I expect something else. I expect you to do certain things for me,” or, “I expect you to pay for certain things for me.”
Covert contracts are the signature of everything bad. Overt contracts are the signature of all things good. And I think about this a lot because I’ve seen a lot of examples of this. I’ve… Like anyone, we participate in these things whether or not we want to or not and the thing that gets transacted the most is… Well, I should say the things that get transacted the most are the overt things. You’ll see money, time, sex, property, whatever it happens to be, information. But what ends up happening is that when people, I believe, don’t feel safe, they feel threatened in some way, like they don’t feel safe in a certain interaction, what they do is they start taking something else while still engaging in the exchange. And I’ll tell you, if there’s one thing about human nature that’s bad, it’s that feature.
Why that feature? Or, “Is it a bug or a feature?” as you engineers like to say. I think it’s because we were allocated a certain extra amount of prefrontal cortex that makes us more sophisticated than a dog, more sophisticated than a chimpanzee, but they do it too. And it’s because it’s often harder, in the short term, to deal with the real sense of, “This is scary. This feels threatening,” than it is to play out all the iterations. It takes a lot of brain work. You’re playing chess and go simultaneously trying to figure out where things are going to end up and we just don’t know.
So it’s a way, I think, of creating a false sense of certainty. But I’ll tell you, covert contracts, the only certainty is that it’s going to end badly. The question is, how badly? Conversely, overt contracts always end well, always. The problem with overt contracts is that you can’t be certain that the other person is not engaging in a covert contract. You can only take responsibility for your own contracting.
Okay, this has to do with eyespots. This was during a government shutdown period where the ghost shrimp that they normally feed eat on, that we would ship in from the gulf down here, weren’t available to us. So we had to get different shrimp. And what we noticed was the cuttlefish normally would just sneak up on the shrimp. We learned this by data collection. And if the shrimp was facing them, they would do this thing with their tentacles of enchanting the shrimp. And if the shrimp wasn’t facing them, they wouldn’t do it and they would ballistically grab it and eat them.
Well, when we got these new shrimp, the new shrimp had eyespots on their tails and then the cuttlefish would do this attempt to enchant, regardless of the position of the ghost shrimp. So what does that mean? Okay, well, it means that there’s some sort of algorithm in the cuttlefish’s mind that says, “Okay, if you see two spots, move your tentacles.” So it can be, as you pointed out, it can be a fairly simple operation, but it looks diabolical. It looks cunning, but all it is strategy B.
This is something people don’t often understand about genetics, is that it only takes a few generations to devolve a trait, make it worse, but it takes a long time to evolve an adaptive trait. There are exceptions to that, but most often that’s true. So a species needs a lot of generations. We are hopefully still evolving as a species. And it takes a long time, to evolve more adaptive traits, but doesn’t take long to devolve adaptive traits, so that you’re getting sicker or you’re not functioning as well. So choose your mate wisely, and that’s perhaps the good segue into sexual selection in humans.
Earlier we were talking about peace, and I think that that sense of peace comes from knowing that the person you’re in friendship with, or that you’re in romantic relationship, or ideally both, because let’s assume the best romantic relationship includes a friendship component with that person. It’s like you just really delight in their presence, even if it’s a quiet presence. And you delight in seeing them delight in things, that’s clear.
But I think that there seems to be a history of people close to me getting into great relationships, where they were friends for a while first or maybe didn’t sleep together right away, that they actually intentionally deferred on that. This has not been my habit or my experience. I’ve gone the more, I think typical, like, oh, there’s an attraction, like this person, there’s an interest. You explore all dimensions of relationship really quickly except perhaps the moving in part and the having kids part, which because it’s a bigger step, harder to undo without more severe consequences. But I think that whole take it slow thing, I don’t think is about getting to know someone slowly, I think it’s about that physical piece, because that does change the nature of the relationship. And I think it’s because it gets right into the more hardwired, primitive circuitry around our feelings of safety, vulnerability.
There’s something about romantic and sexual interactions, where it’s almost like it’s assets and liabilities, right?
I’ll tell you where I’ve gone badly wrong and where I see other people going badly wrong. There is no rule that says that you have to be attracted to all attractive people, by any means. It’s very important to develop a sense of taste in romantic attractions, I believe. What you really like, in terms of a certain style, a certain way of being, and of course that includes sexuality and sex itself, the verb. But I think it also includes their just general way of being. And when you really adore somebody, you like the way they answer the phone, and when they don’t answer the phone that way, you know something’s off and you want to know. And so I think that the more you can tune up your powers of observation, not looking for things that you like, and the more that stuff just washes over you, the more likely you are to, “Fall in love.” As a mutual friend of ours said to me, “Listen, when it comes to romantic relationships, if it’s not a hundred percent in you, it ain’t happening.”
And I’ve never seen a violation of that statement, where it’s like, yeah, it’s mostly good and they’re this and this, likes the negotiations. Well, already it’s doomed. And that doesn’t mean someone has to be perfect, the relationship has to be perfect, but it’s got to feel hundred percent inside.
Okay, the data on position is very interesting, but let me just say a few things. There are a few clinics now, in particular some out of the United States, that are spinning down sperm and finding that they can separate out fractions, as they’re called. They can spin the sperm down at a given speed, and that they’ll separate out at different depths within the test tube, that allow them to pull out the sperm on top or below and bias the probability towards male or female births. It’s not perfect. It’s not a hundred percent. It’s a very costly procedure. It’s still very controversial.
Now with in vitro fertilization, they can extract eggs. You can introduce a sperm, directly by pipette, it’s a process called ICSI. Or you can set up a sperm race in a dish. And if you get a number of different embryos, meaning the eggs get fertilized, duplicate and start form a blastocyst, which is a ball of cells, early embryo, then you can do karyotyping. So you can do look for XX or XY, select the XY, which then would give rise to a male offspring, and then implant that one. So there is that kind of sex selection.
With respect to position, there’s a lot of lore that if the woman is on top or the woman’s on the bottom, or whether or not the penetration is from behind, whether or not it’s going to be male or female offspring. And frankly, the data are not great, as you can imagine, because those-
But others that I sought out, and not specifically for this answer, but for researching that episode, said that, “Yeah, what you’re talking about is trying to get the maximum number of sperm and it’s contained in semen. And yes, the semen can leak out. And so keeping the pelvis tilted for about 15 degrees for about 15 minutes, obviously tilted in the direction that would have things running upstream, not downstream, so to speak.”
And in the podcast, we did talk about both male and female orgasm. We talked a lot about sexual function and dysfunction. We talked a lot about pelvic floor. One interesting factoid is that only 3% of sexual dysfunction is hormonal, endocrine, in nature. It’s more often related to some pelvic floor or vasculature, blood flow related or other issue. And then when Eisenberg came on the podcast, he said that far less sexual dysfunction is psychogenic in origin than people believe. That far more of it is pelvic floor, neuro and vascular. It’s not saying that psychogenic dysfunction doesn’t exist, but that a lot of the sexual dysfunction that people assume is related to hormones or that is related to psychogenic issues are related to vascular or neural issues. And the good news is that there are great remedies for those. And so both those episodes detail some of the more salient points around what those remedies are and could be.
One of the, again, factoids, but it was interesting that a lot of people have pelvic floor issues and they think that their pelvic floors are, quote, unquote, messed up. So they go on the internet, they learn about Kegels. And it turns out that some people need Kegels, they need to strengthen their pelvic floor. Guess what? A huge number of people with sexual and urologic dysfunction have pelvic floors that are too tight and Kegels are going to make them far worse, and they actually need to learn to relax their pelvic floor. And so seeing a pelvic floor specialist is important.
I think in the next five, 10 years, we’re going to see a dramatic shift towards more discussion about sexual and reproductive health in a way that acknowledges that, yeah, the clitoris comes from the same origin tissue as the penis. And in many ways the neural innervation of the two, while clearly different, has some overlapping features that there’s going to be discussion around anatomy and hormones and pelvic floors in a way that’s going to erode some of the cloaking of these topics because they’ve been cloaked for a long time and there’s a lot of… Well, let’s just call it what it is. There’s a lot of bullshit out there about what’s what.
Now, the hormonal issues, by the way, just to clarify, can impact desire. So a lot of people who have lack of desire as opposed to lack of anatomical function, this could be male or female that can originate with either things like SSRIs or hormonal issues. And so we talk about that as well. So it’s a pretty vast topic.
And then I’m looking for papers that establish a thoroughness of understanding. That are interesting, obviously. It’s fun to get occasionally look at some of the odder or more progressive papers that are what’s new in a field and then where there are actionable takeaways to really export those with a lot of thoughtfulness.
Going back to the productivity thing I do, I get up, I look at the sun. I don’t stare at the sun, but I get my sunshine. It all starts with a really good night’s sleep. I think that’s really important to understand. So much so that if I wake up and I don’t feel rested enough, I’ll often do a non-sleep deep rest yoga nidra, or go back to sleep for a little bit, get up, really prioritize the big block of work for the thing that I’m researching. I think a little bit of anxiety and a little bit of concern about deadline helps. Turning the phone off helps, realizing that those peak hours, whenever they are for you, you do not allow those hours to be invaded, unless a nuclear bomb goes off. And nuclear bomb is just a phraseology for, family crisis would be good justification. If there’s an emergency, obviously.
But it’s all about focus. It’s all about focus in the moment. It’s not even so much about how many hours you log. It’s really about focus in the moment. How much total focus can you give to something? And then I like to take walks and think about things and sometimes talk about them in my voice recorder. So I’m just always churning on it, all the time. And then of course, learning to turn it off and engage with people socially and not be podcasting 24 hours a day in your head is key. But I think I love learning and researching and finding those papers and the information, and I love teaching it.
And these days I use a whiteboard before I start. I don’t have any notes, no teleprompter. Then the whiteboard that I use beforehand is to really sculpt out the different elements and the flow, get the flow right and move things around. The whiteboard is such a valuable tool. Then take a couple pictures of that when I’m happy with it, put it down on the desk and these are just bullet points and then just churn through and just churn through. And nothing feels better than researching and sharing information. And I, as you did, grew up writing papers and it’s hard. And I like the friction of, “Uh, can’t. I want to get up. I want to use the bathroom.”
When I was in college, I was trying to make up deficiencies from my lack of attendance in high school, so much so that I would set a timer. I wouldn’t let myself get up to use the bathroom even. Never had an accident. I listened to music, classical music, Rancid, a few other things. Some Bob Dylan maybe thrown in there and just study and just… And then you’d hit the two-hour mark and you’re in pain and then you get up, use the bathroom. You’re like, “That felt so good.” There’s something about the human brain that likes these kind of friction points and working through them and you just have to work through them.
So yeah, I’m productive and my life has arranged around it, and that’s been a bit of a barrier to personal life at times. But my life’s been arranged around it. I’ve set up everything so that I can learn more, teach more, including some of my home life. But I do still watch Chimp Empire. I still got time to watch Chimp Empire. Look, the great Joe Strummer, Clash, they were my favorite Mescaleros. He said, this famous Strummer quote, “No input, no output.” So you need experience. You need outside things in order to foster the process.
But yeah, just nose to the grindstone man, I don’t know. And that’s what I’m happy to do with my life. I don’t think anyone should do that just because. But this is how I’m showing up. And if you don’t like me, then scroll… What do they say? Swipe left, swipe right. I don’t know. I’m not on the apps, the dating apps. So that’s the other thing. I keep waiting for when, “Listens to Lex Fridman podcast,” is a checkbox on Hinge or Bumble or whatever it is. But I don’t even know. Are those their field? I don’t know. What are the apps now?
And then as we’ve gotten into topics that are a little bit further away from my home knowledge, I still get super excited about it. This music in the brain episode I’ve been researching for a while now, I’m just so hyped about it. It’s so, so interesting. There’s so many facets. Singing versus improvisational music versus, “I’m listening to music,” versus learning music. It just goes on and on. There’s just so much that’s so interesting. I just can’t get enough. And I think, I don’t know, you put a camera in front of me, I sort of forget about it and I’m just trying to just teach.
But yeah, just tap into that energy of learning and loving it. And people are along for the ride. I get accused of being long-winded, but things get taken out of context, that leads to greater misunderstanding. And also, listen, I come from a lineage of three dead advisors. Three. All three. So I don’t know when the reaper’s coming for me. I’m doing my best to stay alive a long time. But whether or not it’s a bullet or a bus or cancer or whatever, or just old age, I’m trying to get it all out there as best I can. And if it means you have to hit pause and come back a day or two later, that seems like a reasonable compromise to me. I’m not going to go longer than I need to and I’m trying to shorten them up. But again, that’s kind of how I show up.
It’s like Tim Armstrong would say about writing songs. I asked him, “How often do you write?” Every day. Every day. Does Rick ever stop creating? No. Has Joe ever stopped preparing for comedy? Are you ever stopping to think about world issues and technology and who you can talk to? It seems to me you’ve always got a plan in sight. The thing I love about your podcast the most, to be honest these days, is the surprise of I don’t know who the hell’s going to be there. It’s almost like I get a little nervously excited about when a new episode comes out. I have no idea. No idea. I have some guesses based on what you told me during the break. You’ve got some people where it’s just like, “Whoa, Lex went there? Awesome. Can’t wait.” Click. I think that’s really cool. You’re constantly surprising people. So you’re doing it so well. It’s such a high level and I think it’s also important for people to understand that what you’re doing Lex, there’s no precedent for it. Sure. There’ve been interviews before, there have been podcasts before. There are discussions before. How many of your peers can you look to find out how best to do the content like yours? Zero. There’s one peer: you. And so that should give you great peace and great excitement because you’re a pioneer. You’re literally the tip of the spear.
I don’t want to take an unnecessary tangent, but I think this might thread together two of the things that we’ve been talking about, which are, I think of pretty key importance. One is romantic relationships, and the other is creative process and work. And this again, is something I learned from Rick, but that he and I have gone back and forth on. And that I think is worth elaborating on, which is earlier we were saying the best relationship is going to be one where it brings you peace. I think peace also can be translated to, among other things, lack of distraction. So when you’re with your partner, can you really focus on them and the relationship? Can you not be distracted by things that you’re upset about from their past or from your past with them? And of course the same is true for them, right? They ideally will feel that way towards you too. They can really focus.
Also, when you’re not with them, can you focus on your work? Can you not be worried about whether or not they’re okay because you trust that they’re an adult and they can handle things or they will reach out if they need things? They’re going to communicate their needs like an adult. Not creating messes just to get attention and things like that, or disappearing for that matter. So peace and focus are intimately related, and distraction is the enemy of peace and focus.
So there’s something there, I believe, because with people that have the strong generative drive and want to be productive in their home life, in the sense have a rich family life, partner life, whatever that is, and in their work life, the ability to really drop into the work and you might have that sense like, “I hope they’re okay,” or, “need to check my phone or something,” but just know we’re good.
And the craziest thing happened, Lex. It was unbelievable. I’ve never had an experience like this. I expected my heart to break, and I’ve felt a broken heart before. I felt it, frankly, when my parents split, I felt it when Harry shot himself. I felt it when Barbara died and felt it when Ben went as well. And so many friends, way too many friends. The end of 2017, my friend Aaron King, Johnny Fair, John Eikleberry, stomach cancer, suicide, fentanyl. I was like, “Whoa. All in a fricking week.” And I just remember thinking, “What the…?” And it’s just heartbreak and you just carry that and it’s like, “Uh.” And that’s just a short list. And I don’t say that for sob stories. It’s just for a guy that wasn’t in the military or didn’t grow up in the inner city, it’s an unusual number of deaths, close people.
When Costello went, the craziest thing happened. My heart warmed up, it heated up. And I wasn’t on MDMA. The moment he went, it just went whoosh. And I was like, “What the hell is this?” And it was a supernatural experience to me. I just never had that. I put my grandfather on the ground, I was a pallbearer at the funeral. I’ve done that more times than I’d like to have ever done it. And it just heated up with Costello and I thought, “What the fuck is this?”
And it was almost like, and we make up these stories about what it is, but it was almost like he was like, “All right,” I have to be careful because I will cry here and I don’t want to. It was almost like he was like all that effort, because I had been putting so much effort into him, it was like, “All right, you get that back.” It was like the giant freaking, “Thank you.” And it was incredible. And I’m not embarrassed to shed a tear or two about it if I have to.
I was like, “Holy shit.” That’s how close I was to that animal.
When I think about Barbara especially, I well up and it’s hard for me, but I talked to her before she died and that was a brutal conversation, saying goodbye to someone, especially with kids. And that was hard. I think that really flipped a switch in me where I’m like, I always knew I wanted kids. I’d say, “I want kids. I want a lot of kids.” That flipped a switch in me. I was like, “I want kids. I want my own kids.”

Introduction
Andrew Huberman
Listen, when it comes to romantic relationships, if it’s not a 100% in you, it ain’t happening. And I’ve never seen a violation of that statement where it’s like, “Yeah, it’s mostly good.” And this is like the negotiations, already it’s doomed. And that doesn’t mean someone has to be perfect. The relationship has to be perfect, but it’s got to feel a 100% inside, like yes, yes, and yes.

The following is a conversation with my dear friend Andrew Huberman, his fourth time on this podcast. It’s my birthday, so this is a special birthday episode of sorts. Andrew flew down to Austin just to wish me a happy birthday, and we decided to do a podcast last second. We literally talked for hours beforehand and a long time after late into the night. He’s one of my favorite human beings, brilliant scientists, incredible teacher, and a loyal friend. I’m grateful for Andrew. I’m grateful for good friends, for all the support and love I’ve gotten over the past few years. I’m truly grateful for this life, for the years, the days, the minutes, the seconds I’ve gotten to live on this beautiful earth of ours. I really don’t want to leave just yet. I think I’d really like to stick around. I love you all. This is the Lex Fridman podcast. And now, dear friends, here’s Andrew Huberman.

Exercise routine
Andrew Huberman
I’m trying to run a little bit more.
I’m trying to run a little bit more.
Lex Fridman
Are you losing weight?
Are you losing weight?
Andrew Huberman
I’m not trying to lose weight, but I always do the same fitness routine after 30 years. Basically lift three days a week, run three days a week, but one of the runs is the long run, one of them is medium, one of them is a sprint type thing. So what I’ve decided to do this year was just extend the duration of the long run. And I like being mobile. I never want to be so heavy that I can’t move. I want to be able to go out and run 10 miles if I have to so sometimes I do. And I want to be able to sprint if I have to. So sometimes I do.

And lifting in objects feels good. It feels good to train like a lazy bear and just lift heavy objects. But I’ve also started training with lighter weights and higher repetitions and for three month cycles, and it gives your joints a rest. Yeah, so I think it also is interesting to see how training differently changes your cognition. That’s probably hormone related, hormones downstream of training heavy versus hormones downstream of training a little bit lighter. I think my cognition is better when I’m doing more cardio and when the repetition ranges are a little bit or higher, which is not to say that people who lift heavy are dumb, but there is a… Because there’s real value in lifting heavy.
Lex Fridman
There’s a lot of angry people listening to this right now.
There’s a lot of angry people listening to this right now.
Andrew Huberman
No, no, no. But lifting heavy and then taking three to five minutes rest is far and away a different challenge than running hard for 90 minutes. That’s a tough thing, just like getting in an ice bath. People say, “Oh, well, how is that any different than working out?” Well, there are a lot of differences, but one of them is that it’s very acute stress, within one second you’re stressed. So I think subjecting the body to a bunch of different types of stressors in space and time is really valuable. So yeah, I’ve been playing with the variables in a pre systematic way.

It can take away that hyperfocus and put you more in a relaxed focus for sure.

Lex Fridman
Well, for me, it brings the clutter to the surface at first. Like all these thoughts come in there, and then they dissipate. I got knee barred pretty hard. That’s when somebody tries to break your knee.

Oh, so you tap so they-
Oh, so you tap so they-
Lex Fridman
Yeah. Yeah. So it’s hyperextend the knee in that direction, they got knee barred pretty hard. So in ways I don’t understand, it kind of hurts to run. I don’t understand what’s happening behind there. I need to investigate this. Basically the hamstringing flex, like curling, your leg hurts a little bit, and that results in this weird, dull, but sometimes extremely sharp pain in the back of the knee. So I’m working through this anyway, but walking doesn’t hurt.

So I’m working through this anyway, but walking doesn’t hurt.
So I’ve been playing around with walking recently for two hours and thinking because I know a lot of smart people throughout history, I have walked and thought, and you have to play with things that have worked for others, not just to exercise, but to integrate this very light kind of prolonged exercise into a productive life. So they do all their thinking while they walk. It’s like a meditative type of walking, and it’s really interesting. It really works.
Andrew Huberman
Yeah. The practice I’ve been doing a lot more of lately is I walk while reading a book in the yard. I’ll just pace back and forth or walk in a circle.

Well, you just holding.

Andrew Huberman
I’m holding the book and I’m walking and I’m reading, and I usually have a pen and I’m underlining. I have this whole system like underlining, stars, exclamation points, goes back to university of what things I’ll go back to which things I export to notes and that kind of thing. But from the beginning when I opened my lab at that time in San Diego before I moved back to Stanford, I would have meetings with my students or postdocs by just walking in the field behind the lab. And I’d bring my bulldog Costello, bulldog Mastiff at the time, and he was a slow walker. So these were slow walks, but I can think much more clearly that way. There’s a Nobel Prize winning professor at Columbia University School of Medicine, Richard Axel, who won the Nobel Prize, co-won Nobel Prize with Linda Buck for the discovery of the molecular basis of olfaction.

And he walks in, voice dictates his papers. And now with Rev or these other, maybe there are better ones than Rev, where you can convert audio files into text very quickly and then edit from there. So I will often voice dictate first drafts and things like that. And I totally agree on the long runs, the walks, the integrating that with cognitive work, harder to do with sprints and then the gym. You weight train?
Lex Fridman
Yeah.
Yeah.
Andrew Huberman
You just seem naturally strong and thicker jointed. It’s true, it’s true.

You guys have a certain similarity. He had wrists like it’s like you know. You and Jocko and Costello have these wrists and elbows that are super thick. And then when you look around, you see tremendous variation. Some people have the wrist width of a Whippet or Woody Allen, and then other people like you or Jocko. There’s this one Jocko video or thing on GQ or something. Have you seen the comments on Jocko, These are the Best?

No.
No.

Advice to younger self
Lex Fridman
So this is technically a birthday podcast. What do you love most about getting older?
So this is technically a birthday podcast. What do you love most about getting older?
Andrew Huberman
It’s like the confirmation that comes from getting more and more data, which basically says, ” Yeah, the first time you thought that thing, it was actually right because the second, third and fourth and fifth time, it turned out the exact same way.” In other words, there have been a few times in my life where I did not feel easy about something. I felt a signal for my body, “This is not good.” And I didn’t trust it early on, but I knew it was there.

I felt a signal for my body, “This is not good.” And I didn’t trust it early on, but I knew it was there.
And then two or three bad experiences later, I’m able to say, “Ah, every single time there was a signal from the body informing my mind, this is not good.” Now the reverse has also been true that there’ve been a number of instances in which I feel there sort of immediate delight, and there’s this almost astonishingly simple experience of feeling comfortable with somebody or at peace with something or delighted at an experience. And it turns out literally all of those experiences and people turned out to be experiences and people that are still in my life and that I still delight in every day. In other words, what’s great about getting older is that you stop questioning the signals that come from, I think deeper recesses of your nervous system to say, “Hey, this is not good,” or, “Hey, this is great, more of this.” Whereas I think in my teens, my twenties, my thirties, I’m almost 48, I’ll be 48 next month.
I didn’t trust, I didn’t listen. I actually put a lot of work into overriding those signals and learning to fight through them, thinking that somehow that was making me tougher or somehow that was making me smarter. When in fact, in the end, those people that you meet that are difficult or there are other names for it, like in the end, you’re like, “That person’s a piece of shit,” or, “This person is amazing and they’re really wonderful.” And I felt that from the go.
Lex Fridman
So you’ve learned to trust your gut versus the influences of other people’s opinions?
So you’ve learned to trust your gut versus the influences of other people’s opinions?
Andrew Huberman
I’ve learned to trust my gut versus the forebrain over analysis, overriding the gut. Other people often in my life have had great optics. I’ve benefited tremendously from an early age of being in a large community. It’s been mostly guys, but I have some close female friends and always have as well who will tell me, “That’s a bad decision,” or, “This person not so good,” or, “Be careful,” or, “They’re great,” or, “That’s great.” So oftentimes my community and the people around me have been more aligned with the correct choice than not.

… done with a clinician. Thank you very much. Thank you. I was worried there for a second at one point. “Am I not coming back?” But in any event, yeah, I grew up with some wild kids. I would say about a third of my friends from childhood are dead or in jail, about a third have gone on to do tremendously impressive things, start companies, excellent athletes, academics, scientists, and clinicians. And then about a third are living their lives as more typical. I just mean that they are happy family people with jobs that they mainly serve the function to make money. They’re not into their career for career’s sake.

And then about a third are living their lives as more typical. I just mean that they are happy family people with jobs that they mainly serve the function to make money. They’re not into their career for career’s sake.
So some of my friends early on gave me some bad ideas, but most of the time my bad ideas came from overriding the signals that I knew that my body, and I would say my body and brain were telling me to obey, and I say body and brain is that there’s this brain region, the insula, which does many things, but it represents our sense of internal sensation and interoception. And I was talking to Paul Conte about this, who as you know, I respect tremendously. I think he’s one of the smartest people I’ve ever met. I think for different reasons. He and Marc Andreessen are some of the smartest people I’ve ever met. But Paul’s level of insight into the human psyche is absolutely astounding. And he says the opposite of what most people say about the brain, which is most people say, “Oh, the supercomputer of the brain is the forebrain.”
It’s like a monkey brain with a extra real estate put on there. And the forebrain is what makes us human and gives us our superpowers. Paul has said, and he’s done a whole series on mental health that’s coming out from our podcast in September, so this is not an attempt to plug that, but he’ll elaborate on [inaudible 00:13:08].
Lex Fridman
Wait, you’re doing a thing with Paul?
Wait, you’re doing a thing with Paul?
Andrew Huberman
We already did. Yeah.
We already did. Yeah.
Lex Fridman
Oh, nice.
Oh, nice.
Andrew Huberman
So Paul Conte, he and I sat down, he did a four episode series on mental health. This is not mental illness mental health, about how to explore one’s own subconscious, explore the self, build and cultivate the generative drive. You’ll learn more about what that is from him. He’s far more eloquent and clearer than I am, and he provides essentially a set of steps to explore the self that does not require that you work with a therapist.

This is self-exploration that is rooted in psychiatry, it’s rooted in neuroscience, and I don’t think this information exists anywhere else. I’m not aware that it exists anywhere else. And he essentially distills it all down to one eight and a half by 11 sheet, which we provide for people. And he says there, I don’t want to give too much away because I would detract from what he does so beautifully, but if I tried and I wouldn’t have accomplish it anyway.
But he said, and I believe that the subconscious is the supercomputer of the brain. All the stuff working underneath our conscious awareness that’s driving our feelings and what we think are the decisions that we’ve thought through so carefully. And that only by exploring the subconscious and understanding it a little bit, can we actually improve ourselves over time and I agree. I think that so the mistake is to think that thinking can override it all. It’s a certain style of introspection and thinking that allows us to read the signals from our body, read the signals from our brain, integrate the knowledge that we’re collecting about ourselves, and to use all that in ways that are really adaptive and generative for us.
Jungian shadow
Lex Fridman
What do you think is there in that subconscious? What do you think of the Jungian and shadow? What’s there?
What do you think is there in that subconscious? What do you think of the Jungian and shadow? What’s there?
Andrew Huberman
There’s this idea, as you’re familiar with too. I’m sure that this Jungian idea that we all have all things inside of us, that all of us have the capacity to be evil, to be good, et cetera, but that some people express one or the other to a greater extent. But he also mentioned that there’s a unique category of people, maybe 2 to 5% of people that don’t just have all things inside of them, but they actually spend a lot of time exploring a lot of those things. The darker recesses, the shadows, their own shadows.

The darker recesses, the shadows, their own shadows.
I’m somebody who’s drawn to goodness and to light and to joy and all those things like anybody else. But I think maybe it was part of how I grew up. Maybe it was the crowd I was with, but then again, even when I started spending more time with academics and scientists, I mean you see shadows in other ways, right? You see pure ambition with no passion. I recall a colleague in San Diego who it was very clear to me did not actually care about understanding the brain, but understanding the brain was just his avenue to exercise ambition. And if you gave him something else to work on, he’d work on that.
In fact, he did. He left and he worked on something else, and I realized he has no passion for understanding the brain like I assumed all scientists do, certainly why I went into it. But some people, it’s just raw ambition. It’s about winning. It doesn’t even matter what they win, which to me is crazy. But I think that’s a shadow that some people explore, not one I’ve explored. I think the shadow parts of us are very important to come to understand and look better to understand them and know that they’re there and work with them than to not acknowledge their presence and have them surface in the form of addictions or behaviors that damage us in other people.

So one of the processes for achieving mental health is to bring those things to the surface. So fish the subconscious mind.

Yes, and Paul describes 10 cupboards that one can look into for exploring the self. There’s the structure of self and the function of self. Again, this will all be spelled out in this series in a lot of detail. Also in terms of its relational aspect between people, how to pick good partners and good relationship. It gets really into this from a very different perspective. Yeah, fascinating stuff. I was just sitting there. I will say this, that four episode series with Paul is at least to date, the most important work I’ve ever been involved in in all of my career because it’s very clear that we are not taught how to explore our subconscious and that very few people actually understand how to do that. Even most psychiatrists, he mentioned something about psychiatrists. If you’re a cardiothoracic surgeon or something like that and 50% of your patients die, you’re considered a bad cardiothoracic surgeon.

If you’re a cardiothoracic surgeon or something like that and 50% of your patients die, you’re considered a bad cardiothoracic surgeon.
But with no disrespect to psychiatrists, there are some excellent psychiatrists out there. There are also a lot of terrible psychiatrists out there because unless all of their patients commit suicide or half commit suicide, they can treat for a long time without it becoming visible that they’re not so good at their craft. Now, he’s superb at his craft, and I think he would say that yes, exploring some shadows, but also just understanding the self, really understanding like, “Who am I? And what’s important? What are my ambitions? What are my strivings?” Again, I’m lifting from some of the things that he’ll describe exactly how to do this. People do not spend enough time addressing those questions, and as a consequence, they discover what resides in their subconscious through the sometimes bad, hopefully also good, but manifestations of their actions.
We are driven by this huge 90% of our real estate that is not visible to our conscious awareness. And we need to understand that. I’ve talked about this before. I’ve done therapy twice a week since I was a kid. I had to as a condition of being let back in school. I found a way to either through insurance or even when I didn’t have insurance, I took an extra job writing for Thrasher Magazine when I was a postdoc so I could pay for therapy at a discount because I didn’t make much money as a postdoc.
I mean, I think for me, it’s as important as going to the gym and people think it’s just ruminating on problems, or getting… No, no, no. If you work with somebody really good, they’re forcing you to ask questions about who you really are, what you really want. It’s not just about support, but there should be support. There should be rapport, but then it’s also, there should be insight, right? Most people who get therapy, they’re getting support, there’s rapport, but insight is not easy to arrive at, and a really good psychologist or psychiatrist can help you arrive at deep insights that transform your entire life.
Betrayal and loyalty
Lex Fridman
Well, sometimes when I look inside and I do this often exploring who you truly are, you come to this question, do I accept… Once you see parts, do I accept this or do I fix this? Is this who you are fundamentally, and it will always be this way, or is this a problem to be fixed? For example, one of the things, especially recently, but in general over time I’ve discovered about myself probably has roots in childhood, probably has roots in a lot of things, is I deeply value loyalty maybe more than the average person. And so when there’s disloyalty, it can be painful to me. And so this is who I am, and so do I have to relax a bit? Do I have to fix this part or is this who you are? And there’s a million, that’s one little…

Andrew Huberman
I think loyalty is a good thing to cling to, provided that when loyalty is broken, that it doesn’t disrupt too many other areas of your life. But it depends also on whose disrupting that loyalty, if it’s a coworker versus a romantic partner versus your exclusive romantic partner, depending on the structure of your romantic partner life. I mean, I have always experienced extreme joy and feelings of safety and trust in my friendships. Again, mostly male friendships, but female friendships too, which is only to say that they were mostly male friendships. The female friendships have also been very loyal. So getting backstabbed is not something I’m familiar with. And yeah, I love being crewed up.

Lex Fridman
Yeah. No, for sure. And I’m with you and you and I very much have the same values on this, but that’s one little thing. And then there’s many other things like I’m extremely self-critical and I look at myself as I’m regularly very self-critical, a self-critical engine in my brain. And I talked to actually Paul about this, I think on the podcast quite a bit. And he’s saying, “This is a really bad thing. You need to fix this. You need to be able to be regularly very positive about yourself.” And I kept disagreeing with him, “No, this is who I am,” and he seems to work. Don’t mess with a thing that seems to be working. It’s fine.

It’s fine.
I oscillate between being really grateful and really self-critical. But then you have to figure out what is it? Maybe there’s a deeper root thing. Maybe there’s an insecurity in there somewhere that has to do with childhood and then you’re trying to prove something to somebody from your childhood, this kind of thing.
Andrew Huberman
Well, a couple of things that I think are hopefully valuable for people here. One is one way to destroy your life is to spend time trying to control your or somebody else’s past. So much of our destructive behavior and thinking comes from wanting something that we saw or did or heard to not be true, rather than really working with that and getting close to what it really was. Sometimes those things are even traumatic, and we need to really get close to them and for them to move through us. And there are a bunch of different ways to do that with support from others and hopefully, but sometimes on our own as well.

Sometimes those things are even traumatic, and we need to really get close to them and for them to move through us. And there are a bunch of different ways to do that with support from others and hopefully, but sometimes on our own as well.
I don’t think we can rewire our deep preferences and what we find despicable or joyful. I do think that it’s really a question of what allows us peace. Can you be at peace with the fact that you’re very self-critical? And enjoy that, get some distance from it, have a sense of humor about it, or is it driving you in a way that’s keeping you awake at night and forcing you back to the table to do work in a way that feels self-flagellating and doesn’t feel good?
Can you get that humility and awareness of your one’s flaws? And I think that that can create, this word space sounds very new, edgy, like get space from it. You can have a sense of humor about how neurotic we can all be. I mean, neurotic isn’t actually a bad term in the classic sense of the psychologists and psychiatrists, the freudians. So that the best case is to be neurotic, to actually see one’s own issues and work with them. Whereas psychotic is the other way to be, which is obviously not good. So I think the question whether or not to work on something or to just accept it as part of ourselves, I think really depends if we feel like it’s holding us back or not. And I think you’re asking perhaps the most profound question about being a human, which is what do you do with your body? What do you do with your mind?
I mean, it’s also a question. We started off talking about fitness a little bit just for whatever reason. Do I need to run an ultra marathon? I don’t feel like I need to. David Goggins does and does a whole lot more than that. So that for him, that’s important. For me, it’s not important to do that. I don’t think he does it just so he can run the ultras. There’s clearly something else in there for him. And guys like Cam Hanes and tremendous respect for what they do and how they do it. Does one need to make their body more muscular, stronger, more endurance, more flexibility? Do you need to read harder books? I think doing hard things feels good. I know it feels good. I know that the worst I feel, the worst way to feel is when I’m procrastinating and I don’t do something.
And then whenever I do something and I complete it and I break through that point where it was hard and then I’m doing it at the end, I actually feel like I was infused with some sort of super chemical. And who knows if it’s probably a cocktail of endogenously made chemicals. But I think it is good to do hard things, but you have to be careful not to destroy your body, your mind in the process. And I think it’s about whether or not you can achieve peace. Can you sleep well at night?
Stress isn’t bad if you can sleep well at night, you can be stressed all day, go, go, go, go, go, go, go. And it’ll optimize your focus. But can you fall asleep and stay deeply asleep at night? Being in a hard relationship. Some people say that’s not good. Other people like can you be at peace in that? And I think we all have different RPM. We all kind of idle at different RPM and some people are big mellow Costello and others need more friction in order to feel at peace. But I think ultimately what we want is to feel at peace.
Lex Fridman
Yeah, I’ve been through some really low points over the past couple of years, and I think the reason could be boiled down to the fact that I haven’t been able to find a place of peace, a place or people or moments that give deep inner peace. And I think you put it really beautifully. You have to figure out, given who you are, the various characteristics of your mind, all the things, all the contents of the cupboards, how to get space from it. And ultimately one good representation of that is to be able to laugh at all of it, whatever’s going on inside your mind to be able to step back and just kind of chuckle at the beauty and the absurdity of the whole thing.

Very intense.
Very intense.
Andrew Huberman
Very intense, but embodies all the different emotions. That’s why I love it. They have some love songs, they have some hate songs, they have some in. But going back to what you said, I think there’s a song, the first song on Indestructible album. I think he’s just talking about shock and disbelief of discovering things about people that were close to you. And I won’t sing it, but nor I wouldn’t dare. But there’s this one lyric that’s really stuck in my mind ever since that album came out in 2003, which is that, “Nothing’s what it seems so I just sit here laughing. I’m going to keep going on. I can’t get distracted.” There is this piece of like, you got to learn how to push out the disturbing stuff sometimes and go forward. And I remember hearing that lyric and then writing it down. And that was a time where my undergraduate advisor, who was a mentor and a father to me, blew his head off in the bathtub like three weeks before.

And that was a time where my undergraduate advisor, who was a mentor and a father to me, blew his head off in the bathtub like three weeks before.
And then my graduate advisor, who I was working for at that time, who I loved and adored, was really like a mother to me. I knew her when she was pregnant with her two kids, died at 50, breast cancer. And then my postdoc advisor, first day of work at Stanford as a faculty member sitting across the table like this from him, had a heart attack right in front of me, died of pancreatic cancer at the end of 2017. And I remember just thinking, going back to that song there over and over and where people would… Yeah, I haven’t had many betrayals in life. I’ve had a few. But just thinking or seeing something or learning something about something, you just say you can’t believe it. And I mentioned that lyric off, that first song, Indestructible on that album because it’s just the raw emotion of like, “I can’t believe this. What I just saw is so disturbing, but I have to just keep going forward.”
There are certain things that we really do need to push not just into our periphery, but off into the gutter and keep going. And that’s a hard thing to learn how to do. But if you’re going to be functional in life, you have to. And actually just to get at this issue of do I change or do I embrace this aspect of self? About six months, it was April of this last year, I did some intense work around some things that were really challenging to me. And I did it alone, and it may have involved some medicine, and I expected to get peace through this. I was like, “I’m going to let go of it.” And I spent 11 hours just getting more and more frustrated and angry about this thing that I was trying to resolve.
And I was so unbelievably disappointed that I couldn’t get that relief. And I was like, “What is this? This is not how this is supposed to work. I’m supposed to feel peace. The clouds are supposed to lift.” And so a week went by and then another half week went by, and then someone whose opinion I trust very much. I explained this to them because I was getting a little concerned like, “What’s going on? This is worse, not better.” And they said, ” This is very simple. You have a giant blind spot, which is your sense of justice, Andrew, and your sense of anger are linked like an iron rod and you need to relax it.” And as they said that, I felt the anger dissipate. And so there was something that I think it is true. I have a very strong sense of justice and my sense of anger then at least was very strongly linked to it.
So it’s great to have a sense of justice, right? I hate to see people wrong. I absolutely do. And I’m human. I’m sure I’ve wronged people in my life. I know I have. They’ve told me, I’ve tried to apologize and reconcile where possible. Still have a lot of work to do. But where I see injustice, it draws in my sense of anger in a way that I think is just eating me up. But it was only in hearing that link that I wasn’t aware of before. It was in my subconscious, obviously. Did I feel the relaxation? There’s no amount of plant medicine or MDMA or any kind of chemical you can take that’s naturally just going to dissipate what’s hard for oneself if one embraces that or if one chooses to do it through just talk therapy or journaling or friends or introspection or all of the above. There needs to be an awareness of the things that we’re just not aware of.
So I think the answer to your question, do you embrace or do you fight these aspects of self is? I think you get in your subconscious through good work with somebody skilled. And sometimes that involves the tools I just mentioned in various combinations and you figure it out. You figure out if it’s serving you. Obviously it was not bringing me peace. My sense of justice was undermining my sense of peace. And so in understanding this link… Now, I would say, in understanding this link between justice and anger, now I think it’s a little bit more of you know, it’s not like a Twizzler stick bendy, but at least it’s not like an iron rod. When I see somebody wronged, I mean it used to just… Like immediately.

But then, I continue to engage in it and it’s taking me off course. And so, there is a place where… I mean, I realize this is probably a kid show too so I want to keep it G-rated. But at some point, for certain things, it makes sense to go, “Fuck that.”

So from that perspective, I think it seems like something like that is inevitable.

So I think he is approaching it as a sport, Elon is approaching it as a spectacle. And I mean, the way he talks about it, he’s a huge fan of history. He talks about all the warriors that have fought throughout history. Look, he wants to really do it at the Coliseum. And the Coliseum is for 400 years, there’s so much great writing about this, I think over 400,000 people have died in the Coliseum, gladiators.

The two tech CEOs are battling it out on sand in a place where gladiators fought to the death and then bears and lions ate prisoners as part of the execution process.

Yeah. My now friend, Tim Armstrong, like I said, lead singer from Rancid. He put it best. He said that Mike Tyson’s life is Shakespearean, down, up, down, up and just that the arcs of his life are just… Sort of an only in America kind of tale too, right?

Drama
Lex Fridman
So speaking of Shakespeare, I’ve recently gotten to know Neri Oxman who’s this incredible scientist that works at the intersection of nature and engineering and she reminded me of this Anna Akhmatova line. This is this great Soviet poet that I really love from over a century ago that each of our lives is a Shakespearean drama raised to the thousand degree. So I have to ask, why do you think humans are attracted to this kind of Shakespearean drama? Is there some aspect we’ve been talking about the subconscious mind that pulls us towards the drama, even though the place of mental health is peace?

Lex Fridman
Nice.

Andrew Huberman
Barely passed my classes. The girlfriend and I split up. I mean, I was living in a squat, got into a big fight. I was getting in trouble with the law. I eventually got my act together, go back to school, start working for somebody. Who do I choose to work for? A guy who’s an ex-navy guy who smokes cigarettes in the fume hood, drinks coffee, and we’re injecting rats with MDMA. And I was drawn to the personality, his energy, but I also… He was a great scientist, worked out a lot on a thermal regulation in the brain and more.

And I was drawn to the personality, his energy, but I also… He was a great scientist, worked out a lot on a thermal regulation in the brain and more.
Go to graduate school, I’m working for somebody, and decide that working in her laboratory wasn’t quite right for me. So I’m literally sneaking into the laboratory next door and working for the woman next door because I liked the relationships that she had to a certain set of questions and she was a quirky person. So drawn to drama but drawn to… I like characters. I like people that have texture. And I’m not drawn to raw ambition, I’m drawn to people that seem to have a real passion for what they do and a uniqueness to them that I… Not kind of, I’ll just say how it is. I can feel their heart for what they do and I’m drawn to that and that can be good.
It’s the same reason I went to work for Ben Barris as a post-doc. It wasn’t because he was the first transgender member of the National Academy of Sciences, that was just a feature of who he was. I loved how he loved glial. He would talk about these cells like they were the most enchanting things that he’d ever seen in his life. And I was like, “This is the biggest nerd I’ve ever met and I love him.” I think I’m drawn to that.
This is another thing that Conti elaborates on quite a bit more in the series on mental health coming out. But there are different drives within us, there are aggressive drives. Not always for fighting but for intense interaction. I mean, look at Twitter. Look at some of the… People clearly have an aggressive drive. There’s also a pleasure drive. Some people also have a strong pleasure drive. They want to experience pleasure through food, through sex, through friendship, through adventure. But I think the Shakespearean drama is the drama of the different drives in different ratios in different people.
I know somebody and she’s incredibly kind. Has an extremely high pleasure drive, loves taking great care of herself and people around her through food and through retreats and through all these things and makes spaces beautiful everywhere she goes. And gifts these things that are just so unbelievably feminine and incredible. These gifts to people and then kind and thoughtful about what they like. And then.. But I would say, very little aggressive drive from my read.
And then, I know other people who just have a ton of aggressive drive and very little pressure drive and I think… So there’s this alchemy that exists where people have these things in different ratios. And then, you blend in the differences in the chromosomes and differences in hormones and differences in personal history and what you end up with is a species that creates incredible recipes of drama but also peace, also relief from drama, contentment.
I mean, I realize this isn’t the exact topic of the question. But someone I know very dearly, actually an ex-girlfriend of mine, long- term partner of mine, sent me something recently and I think it hit the nail on the head. Which is that ideally for a man, they eventually settle where they find and feel peace, where they feel peaceful, where they can be themselves and feel peaceful. Now, I’m sure there’s an equivalent or mirror image of that for women but this particular post that she sent was about men and I totally agree.
And so, it isn’t always that we’re seeking friction. But for periods of our life, we seek friction, drama, adventure, excitement, fights, and doing hard, hard things. And then I think at some point, I’m certainly coming to this point now where it’s like, “Yeah. That’s all great and checked a lot of boxes.” But I had a lot of close calls, flew really close to the sun on a lot of things with life and limb and heart and spirit and some people close to us didn’t make it. And sometimes, not making it means the career they wanted went off a cliff or their health went off a cliff or their life went off a cliff. But I think that there’s also the Shakespearean drama of the characters that exit the play and are living their lives happily in the backdrop. It just doesn’t make for as much entertainment.
Lex Fridman
That’s one other thing, you could say, is the benefit of getting older is finding the Shakespearean drama less appealing or finding the joy in the peace.

Andrew Huberman
Yeah. Definitely. I mean, I think there’s real peace with age. I think the other thing is this notion of checking boxes is a real thing, for me anyway. I have a morning meditation that I do. Well, I wake up now, I get my sunlight, I hydrate, I use the bathroom. I do all the things that I talk about. I’ve started a practice of prayer in the last year which is new-ish for me which is we could talk about-

Yeah.
Lex Fridman
Can you talk about it a little bit?
Can you talk about it a little bit?
Andrew Huberman
Sure. Yeah. And then, I have a meditation that I do that actually is where I think through with the different roles that I play. So I start very basic. I say, “Okay. I’m an animal,” like we are biologically animals, human. “I’m a man. I’m a scientist. I’m a teacher. I’m a friend. I’m a brother. I’m a son,” I have this list and I think about the different roles that I have and the roles that I still want in my life going forward that I haven’t yet fulfilled. It just takes me… It’s an inventory of where I’ve been, where I’m at, and where I’m going as they say. And I don’t know why I do it but I started doing it this last year, I think, because it helps me understand just how many different contexts I have to exist in and remind myself that there’s still more that I haven’t done that I’m excited about.

So within each of those contexts, there’s things that you want to accomplish to define that.
So within each of those contexts, there’s things that you want to accomplish to define that.
Andrew Huberman
Yeah, and I’m ambitious so I think… I’m a brother. I have an older sister and I love her tremendously and I think, “I want to be the best brother I can be to her,” which means maybe a call, maybe just we do an annual trip together for our birthdays. Our birthdays are close together. We always go to New York for our birthdays and we’ve gone for the last three, four years. It’s like really reminding myself of that role not because I’ll forget, but because I have all these other roles I’ll get pulled into.

Our birthdays are close together. We always go to New York for our birthdays and we’ve gone for the last three, four years. It’s like really reminding myself of that role not because I’ll forget, but because I have all these other roles I’ll get pulled into.
I say the first one, “I’m an animal,” because I have to remember that I have a body that needs care like any of us. I need sleep, I need food, I need hydration, I need… That I’m human, that the brain of a human is marvelously complex but also marvelously self-defeating at times. And so, I’m thinking about these things in the context of the different roles. And the whole thing takes about four or five minutes and I just find it brings me a certain amount of clarity that then allows me to ratchet into the day.
The prayer piece, I think I’ve been reluctant to talk about until now because I don’t believe in pushing religion on people. And I think that… And I’m not, it’s a highly individual thing and I do believe that one can be an atheist and still pray or agnostic and still pray. But for me, it really came about through understanding that there are certain aspects of myself that I just couldn’t resolve on my own. And no matter how much therapy, no matter how much… And I haven’t done a lot of it. But no matter how much plant medicine or other forms of medicine or exercise or podcasting or science or friendship or any of that, I was just not going to resolve.
And so, I started this because a male friend said, “Prayer is powerful,” and I said, “Well, how?” And he said, “I don’t know how but it can allow you to get outside yourself. Let you give up control and at the same time, take control.” I don’t even like saying take control. But the whole notion is that… And again, forgive me, but there’s no other way to say it. The whole notion is that God works through us. Whatever God is to you, he, him, her, life force, nature, whatever it is to you, that it works through us.
And so, I do a prayer. I’ll just describe it where I make an ask to help remove my character defects. I pray to God to help remove my character defects so that I can show up better in all the roles of my life and do good work which for me is learning and teaching. And so you might say, “Well, how is that different than a meditation?” Well, I’m acknowledging that there is something bigger than me, bigger than nature as I understand it, that I cannot understand or control nor do I want to, and I’m just giving over to that. And does that make me less of a scientist? I sure as hell hope not. I certainly know… There’s the head of our neurosciences at Stanford until recently. You should talk to him directly about it. Bill Newsome has talked about his religious life.
For me, it’s really a way of getting outside myself and then understanding how I fit into this bigger picture. And the character defects part is real, right? I’m a human. I have defects. I got a lot of flaws in me like anybody and trying to acknowledge them and asking for help in removing them. Not magically but through right action, through my right action. So I do that every morning.
And I have to say that it’s helped. It’s helped a lot. It’s helped me be better to myself, be better to other people. I still make mistakes but it’s becoming a bigger part of my life. And I never thought I’d talk like this but I think it’s clear to me that if we don’t believe in something… Again, it doesn’t have to be traditional, standardized religion, but if we don’t believe in something bigger than ourselves, we, at some level, will self-destruct. I really think so.
And it’s powerful in a way that all the other stuff, meditation and all the tools, is not because it’s really operating at a much deeper and bigger level. Yeah. I think that’s all I can talk about it. Mostly because I’m still working out. The scientists in me wants to understand how it works and I want to understand. And the point is to just go, for lack of a better language for it, “There’s a higher power than me and what I can control. I’m giving up control on certain things.” And somehow, that restores a sense of agency for right action and better action.
Lex Fridman
I think perhaps a part of that is just the humility that comes with acknowledging there’s something bigger and more powerful than you.

Andrew Huberman
And that you can’t control everything. I mean, you go through life as a hard driving person, forward center of mass. I remember being that way since I was little. It’s like in Legos. I’m like, “I’m going to make all the Legos.” I was like, on the weekends, learning about medieval weapons and then giving lectures about it in class when I was five or six years old or learning about tropical fish and cataloging all of them at the store. And then, organizing it and making my dad drive me or my mom drive me in some fish store and then spending all my time there until they throw me out. All of that. But I also remember my entire life, I would secretly pray when things were good and things weren’t good. But mostly, when things weren’t good because it’s important to pray. For me, it’s important to pray each morning regardless.

For me, it’s important to pray each morning regardless.
But when things weren’t right, I couldn’t make sense of them, I would secretly pray. But I felt ashamed of that for whatever reason. And then, it was once in college, I distinctly remember I was having a hard time with a number of things and I took a run down to SAN Speech. It was at UC Santa Barbara. And I remember I was like, “I don’t know if I even have the right to do this but I’m just praying,” and I just prayed for the ability to be as brutally honest with myself and with other people as I possibly could be about a particular situation I was in at that time.
I mean, I think now it’s probably safe to say I’d gone off to college because of a high school girlfriend. Essentially, she was my family. Frankly, more than my biological family was at a certain stage of life and we’d reached a point where we were diverging and it was incredibly painful. It was like losing everything I had. And it was like, “What do I do? How do I manage this?” I was ready to quit and join the fire service just to support us so that we could move forward and it was just…
But praying, just saying, “I can’t figure this out on my own.” It’s like, “I can’t figure this out on my own,” and how frustrating that no number of friends could tell me and inner wisdom couldn’t tell me. And eventually, it led me to the right answers. She and I are friendly friends to this day. She’s happily married with a child and we’re on good terms. But I think it’s a scary thing but it’s the best thing when you just, “I can’t control all of this.” And asking for help, I think is also the piece. You’re not asking for some magic hand to come down and take care of it but you’re asking for the help to come through you so that your body is used to do these right works, right action.
Lex Fridman
Isn’t it interesting that this secret thing that you’re almost embarrassed by, that you did as a child is something you… It’s another thing you do as you get older, is you realize those things are part of you and it’s actually a beautiful thing.

Yeah. A lot of the content of the podcast is deep academic content and we talk about everything from eating disorders to bipolar disorder to depression, a lot of different topics. But the tools or the protocols, as we say, the sunlight viewing and all the rest, a lot of that stuff is just stuff I wish I had known when I was in graduate school. If I’d known to go outside every once in a while and get some sunlight, not just stay in the lab, I might not have hit a really tough round of depression when I was a post-doc and working twice as hard.

And when my body would break down or I’d get sick a lot, I don’t get sick much anymore. Occasionally, about once every 18 months to two years, I’ll get something. But I used to break my foot skateboarding all the time, I couldn’t understand. What’s wrong with my body? I’m getting injured. I can’t do what everyone else can. Now, I developed more slowly. I had a long arc of puberty so that was part of it. I was still developing.
But how to get your body stronger, how to build endurance, no one told me. The information wasn’t there. So a lot of what I put out there is the information that I wish I had. Because once I had it, I was like, “Wow.” A, this stuff really works. B, it’s grounded in something real. Sometimes, certain protocols are a combination of animal and human studies, sometimes clinical trials. Sometimes there’s some mechanistic conjecture for some, not all, I always make clear which. But in the end, figuring out how things work so that we can be happier, healthier, more productive, suffer less, reduce the suffering of the world. And I think that… Well, I’ll just say thank you for asking about the prayer piece. Again, I’m not pushing or even encouraging it on anyone. I’ve just found it to be tremendously useful for me.
Chimp Empire
Lex Fridman
I mean, about prayer in general. You said information and figuring out how to get stronger, healthier, smarter, all those kinds of things. A part of me believes that deeply. You can gain a lot of knowledge and wisdom through learning. But a part of me believes that all the wisdom I need was there when I was 11 and 12 years old.

And then, it got cluttered over. Well, listen, I can’t wait for you and Conti to talk again. Because when he gets going about the subconscious and the amount of this that sits below the surface like an iceberg. And the fact that when we’re kids, we’re not obscuring a lot of that subconscious as much. And sometimes, that can look a little more primitive. I mean, a kid that’s disappointed will let you know. A kid that’s excited will let you know and you feel that raw exuberance or that raw dismayal.

And I think that as we grow older, we learn to cover that stuff up. We wear masks and we have to, to be functional. I don’t think we all want to go around just being completely raw. But as you said, as you get older, you get to this point where you go, “Eh. What are we really trying to protect anyway?”
I mean, I have this theory that certainly my experience has taught me that a lot of people but I’ll talk about men because that’s what I know best, whether or not they show up strong or not, that they’re really afraid of being weak. They’re just afraid… Sometimes, the strength is even a way to try and not be weak which is different than being strong for its own sake. I’m not just talking about physical strength. I’m talking about intellectual strength. I’m talking about money. I’m talking about expressing drive. I’ve been watching this series a little bit of Chimp Empire.
Lex Fridman
Oh, yeah.
Oh, yeah.
Andrew Huberman
So Chimp Empire is amazing, right? They have the head chimp. He’s not the head chimp but the alpha in the group and he’s getting older. And so, what does he do? Every once in a while, he goes on these vigor displays. He goes and he grabs a branch. He starts breaking them. He starts thrashing them. And he’s incredibly strong and they’re all watching. I mean, I immediately think of people like they’re deadlifting on Instagram and I just think, “Displays of vigor.” This is just the primate showing displays of vigor. Now, what’s interesting is that he’s doing that specifically to say, “Hey, I still have what it takes to lead this troop.” Then there are the ones that are subordinate to him but not so far behind-

Who gets to mate first, who gets to eat first, this exists in other animal societies too but Bob Sapolsky would be a great person to talk about this with because he knows obviously tremendous amount about it and I know just the top contour. But yeah, so Number 2, 3, and 4 males are aware that he’s doing these vigor displays. But they’re also aware because in primate evolution, they got some extra forebrain too. Not as much as us but they got some. And they’re aware that the vigor displays are displays that… Because they’ve done them as well in a different context, might not just be displays of vigor but might also be an insurance policy against people seeing weakness.

So now, they start using that prefrontal cortex to do some interesting things. So in primate world, if a male is friendly with another male, wants to affiliate with him and say, “Hey, I’m backing you,” they’ll go over and they’ll pick off the little parasites and eat them. And so, the grooming is extremely important. In fact, if they want to ostracize or kill one of the members of their troop, they will just leave it alone. No one will groom it. And then, there’s actually a really disturbing sequence in that show of then the parasites start to eat away on their skin. They get infections. They have issues. No one will mate with them. They have other issues as well and can potentially die.
So the interesting thing is Number 2 and 3 start to line up a strategy to groom this guy but they are actually thinking about overtaking the entire troop setting in a new alpha. But the current alpha did that to get where he is so he knows that they’re doing this grooming thing, but they might not be sincere about the grooming. So what does he do? He takes the whole troop on a raid to another troop and sees who will fight for him and who won’t.
Overt vs covert contracts
This is advanced contracting of behavior for a species that normally we don’t think of as sophisticated as us. So it’s very interesting and it gets to something that I hope we’ll have an opportunity to talk about because it’s something that I’m obsessed with lately, is this notion of overt versus covert contracts, right? There are overt contracts where you exchange work for money or you exchange any number of things in an overt way. But then, there are covert contracts, and those take on a very different form and always lead to, in my belief, bad things.
Lex Fridman
Well, how much of human and chimp relationships are overt versus covert?
Well, how much of human and chimp relationships are overt versus covert?
Andrew Huberman
Well, here’s one thing that we know is true. Dogs and humans, the dog to human relationship is 100% overt. They don’t manipulate you. Now, you could say they do in the sense that they learn that if they look a certain way or roll on their back, they get food. But there’s no banking of that behavior for a future date where then they’re going to undermine you and take your position so in that sense. Dogs can be a little bit manipulative in some sense.
Well, here’s one thing that we know is true. Dogs and humans, the dog to human relationship is 100% overt. They don’t manipulate you. Now, you could say they do in the sense that they learn that if they look a certain way or roll on their back, they get food. But there’s no banking of that behavior for a future date where then they’re going to undermine you and take your position so in that sense. Dogs can be a little bit manipulative in some sense.
But now, okay. So overt contract would be we both want to do some work together, we’re going to make some money, you get X percentage, I get X percentage. It’s overt. Covert contract which is, in my opinion, always bad, would be we’re going to do some work together, you’re going to get a percentage of money, I’m going to get a percentage of money. Could look just like the overt contract but secretly, I’m resentful that I got the percentage that I got. So what I start doing is covertly taking something else. What do I take? Maybe I take the opportunity to jab you verbally every once in a while. Maybe I take the opportunity to show up late. Maybe I take the opportunity to get to know one of your coworkers so that I might start a business with them. That’s covert contracting.
And you see this sometimes in romantic relationships. One person, we won’t set the male or female in any direction here and just say it’s, “I’ll make you feel powerful if you make me feel desired.” Okay. Great. There’s nothing explicitly wrong about that contract if they both know and they both agree. But what if it’s, “I’ll do that but I’ll have kids with you so you feel powerful. You’ll have kids with me so I feel desired. But secretly, I don’t want to do that,” or one person says, “I don’t want to do that,” or both don’t. So what they end up doing is saying, “Okay. So I expect something else. I expect you to do certain things for me,” or, “I expect you to pay for certain things for me.”
Covert contracts are the signature of everything bad. Overt contracts are the signature of all things good. And I think about this a lot because I’ve seen a lot of examples of this. I’ve… Like anyone, we participate in these things whether or not we want to or not and the thing that gets transacted the most is… Well, I should say the things that get transacted the most are the overt things. You’ll see money, time, sex, property, whatever it happens to be, information. But what ends up happening is that when people, I believe, don’t feel safe, they feel threatened in some way, like they don’t feel safe in a certain interaction, what they do is they start taking something else while still engaging in the exchange. And I’ll tell you, if there’s one thing about human nature that’s bad, it’s that feature.
Why that feature? Or, “Is it a bug or a feature?” as you engineers like to say. I think it’s because we were allocated a certain extra amount of prefrontal cortex that makes us more sophisticated than a dog, more sophisticated than a chimpanzee, but they do it too. And it’s because it’s often harder, in the short term, to deal with the real sense of, “This is scary. This feels threatening,” than it is to play out all the iterations. It takes a lot of brain work. You’re playing chess and go simultaneously trying to figure out where things are going to end up and we just don’t know.
So it’s a way, I think, of creating a false sense of certainty. But I’ll tell you, covert contracts, the only certainty is that it’s going to end badly. The question is, how badly? Conversely, overt contracts always end well, always. The problem with overt contracts is that you can’t be certain that the other person is not engaging in a covert contract. You can only take responsibility for your own contracting.
Lex Fridman
Well, one of the challenges of being human is looking at another human being and figuring out their way of being, their behavior, which of the two types of contracts it represents because they look awfully the same on the surface. And one of the challenges of being human, the decision we all make is, are you somebody that takes a leap of trust and trust other humans and are willing to take the hurt or are you going to be cynical and skeptical and avoid most interactions until they, over a long period of time, prove your trust?

Yeah. I never liked the phrase history repeats itself when it comes to humans because it doesn’t apply if the people or the person is actively working to resolve their own flaws.

It does seem like, deep down, we all can tell the difference between overt and covert. We have a good sense. I think one of the benefits of having this characteristic of mine, where I value loyalty, I’ve been extremely fortunate to spend most of my life in overt relationships and I think that creates a really fulfilling life.

Yeah, some close friends of yours have arranged a dinner that I’m really looking forward to. I won’t say which night, but it’s the next couple of nights. Your circadian clock is one of the most robust features of your biology. I know you can be nocturnal or you can be diurnal. We know you’re mostly nocturnal, certain times of the year Lex, but there are very, very few people can get away with no sleep. Very few people can get away with a chaotic sleep-wake schedule. So you have to obey a 24-hour, AKA circadian, rhythm if you want to remain healthy of mind and body. We also have to acknowledge that aging is in linear, right? So-

Well, the degree of change between years 35 and 40, is not going to be the degree of change between 40 and 45.

Yeah, quality of thought, time spent, physically, I can do what I did then, which probably says more about what I could do then than what I can do now. But if you keep training, you can continue to get better. The key is to not get injured, and I’ve never trained super hard. I’ve trained hard, but I’ve been cautious to not, for instance, weight train more than two days in a row. I do a split which is basically three days a week, and the other day’s a run, take one full day off, take a week off every 12 to 16 weeks. I’ve not been the guy hurling the heaviest weights or running the furthest distance, but I have been the guy who’s continuing to do it when a lot of my friends are talking about knee injuries, talking about-

And that’s a difficult decision a lot of people have to make. I have to make with jiujitsu, for example, if you just look empirically. I’ve trained really hard from all my life, in grappling sports and fighting sports and all this kind of stuff, and I’ve avoided injury for the most part. And I would say, I would attribute that to training a lot. Sounds counterintuitive, but training well and safely and correctly, keeping good form saying, “No,” when I need to say no, but training a lot, and taking it seriously. Now when it’s training, it’s really a side thing, I find that the injuries becomes a higher and higher probability.

Talking about inner peace, it brings me so much peace to watch nature, at its worst and at its best. So Life in Color is a series on Netflix where it presents some of the most colorful animals on earth, and tells their story of how they got there through natural selection. So you have the peacock with the feathers and it’s just such incredible colors. The peacock has these tail feathers, the male, that are gigantic and they’re super colorful and they’re these eyes on it. It’s not eyes, it’s eye-like areas. And they wiggle their ass to show the tail, they wiggle the tails.

They’re cows that have multiple calves inside them, and there’s a situation in which the calves will, if there’s more than one inside, will secrete chemicals that will hormonally castrate the calf next to them, so they can’t reproduce. So already in the womb they are fighting for future resources. That’s how early this stuff can start. So it’s chemical warfare in the womb, against the siblings. Sometimes there’s outright siblicide. Siblings are born, they kill one another. This also becomes biblical stories, right? There are instances of cuttlefish, beautiful cephalopods like octopuses, and that is the plural as we made clear.

Yeah, it could be simple algorithm. If there’s some ambiguity about numbers and I’m not with these guys, and then flip to the alternate strategy. I actually have a story about this that I think is relevant. I used to have cuttlefish in my lab in San Diego. We went and got them from a guy out in the desert. We put them in the lab. It was amazing. And they had a postdoc who was studying prey capture in cuttlefish. They have a very ballistic, extremely rapid strike and grab of the shrimp, and we were using high-speed cameras to characterize all this. Looking at binocular, they normally have their eyes on the side of their head, when they see something they want to eat the eyes translocate to the front, which allows them stereopsis death perception, allows them to strike. We were doing some unilateral eye removals they would miss, et cetera.

Okay, this has to do with eyespots. This was during a government shutdown period where the ghost shrimp that they normally feed eat on, that we would ship in from the gulf down here, weren’t available to us. So we had to get different shrimp. And what we noticed was the cuttlefish normally would just sneak up on the shrimp. We learned this by data collection. And if the shrimp was facing them, they would do this thing with their tentacles of enchanting the shrimp. And if the shrimp wasn’t facing them, they wouldn’t do it and they would ballistically grab it and eat them.
Well, when we got these new shrimp, the new shrimp had eyespots on their tails and then the cuttlefish would do this attempt to enchant, regardless of the position of the ghost shrimp. So what does that mean? Okay, well, it means that there’s some sort of algorithm in the cuttlefish’s mind that says, “Okay, if you see two spots, move your tentacles.” So it can be, as you pointed out, it can be a fairly simple operation, but it looks diabolical. It looks cunning, but all it is strategy B.

Because we don’t understand the subconscious. Because that AI algorithm cannot see into what it can’t see. It doesn’t understand the under workings of what allows all of this conversation stuff to manifest. And we can’t even see it, how could AI see it? Maybe it will, maybe AI will solve and give us access to our subconscious. Maybe your AI friend or coach, like I think Andreessen and others are arguing is going to happen at some point, is going to say, “Hey Lex, you’re making decisions lately that are not good for you, but it’s because of this algorithm that you picked up in childhood, that if you don’t state your explicit needs upfront, you’re not going to get what you want. So why do it? From now on, you need to actually make a list of every absolutely outrageous thing that you want, no matter how outrageous, and communicate that immediately, and that will work.”

I think it’s simple contextual engagement of a neural circuit, which is not just nerd speak for saying they do a different strategy. It’s saying that there has to be a circuit there, hardwired circuit, maybe learned, but probably hardwired, that can be engaged, right? You can’t build neural machinery in a moment, you need to build that circuit over time. What is building it over time? You select for it. The cuttlefish that did not have that alternate context-driven circuit, didn’t survive when all the shrimp that they normally eat disappear, and the eyespotted shrimp showed up. And there were a couple that had some miswiring. This is why mutation… Right, X-Men stuff is real. They had a mutation that had some alternate wiring and that wiring got selected for, it became a mutation that was adaptive as opposed to maladaptive.

This is something people don’t often understand about genetics, is that it only takes a few generations to devolve a trait, make it worse, but it takes a long time to evolve an adaptive trait. There are exceptions to that, but most often that’s true. So a species needs a lot of generations. We are hopefully still evolving as a species. And it takes a long time, to evolve more adaptive traits, but doesn’t take long to devolve adaptive traits, so that you’re getting sicker or you’re not functioning as well. So choose your mate wisely, and that’s perhaps the good segue into sexual selection in humans.

Andrew Huberman
Well, I’ve certainly made some mistakes. I’ve also made some good choices in this realm. First of all, we have to define what sort of relationship we’re talking about. If one is looking for a life partner, potentially somebody to establish family with, with or without kids, with or without pets, right? Families can take different forms. I certainly experienced being a family in a prior relationship, where it was the two of us and our two dogs, and it was family. We had our little family. I think, based on my experience, and based on input from friends, who themselves have very successful relationships, I must say, I’ve got friends who are in long-term, monogamous, very happy relationships, where there seems to be a lot of love, a lot of laughter, a lot of challenge and a lot of growth. And both people, it seems, really want to be there and enjoy being there.

Just to pause on that, one thing to do, I think, by way of advice, is listen to people who are in long-term successful relationships.

Definitely, and several members of my podcast team are in excellent relationships. I think one of the things that rings true, over and over again, in the advice and in my experience, is find someone who’s really a great friend, build a really great friendship with that person. Now obviously not just a friend, if we’re talking romantic relationship, and of course sex is super important, but it should be a part of that particular relationship, alongside or meshed with, the friendship. Can it be a majority of the positive exchange? I suppose it could, but I think the friendship piece is extremely important, because what’s required in a successful relationship, clearly is joy in being together, trust, a desire to share experience, both mundane and more adventurous, support each other, acceptance, a real, maybe even admiration, but certainly delight, in being with the person.

Earlier we were talking about peace, and I think that that sense of peace comes from knowing that the person you’re in friendship with, or that you’re in romantic relationship, or ideally both, because let’s assume the best romantic relationship includes a friendship component with that person. It’s like you just really delight in their presence, even if it’s a quiet presence. And you delight in seeing them delight in things, that’s clear.
Lex Fridman
Mm-hmm.

Andrew Huberman
The trust piece is huge and that’s where people start, we don’t want to focus on what works, not what doesn’t work, but that’s where, I think, people start engaging in these covert contracts. They’re afraid of being betrayed, so they betray. They’re afraid of giving up too much vulnerability, so they hide their vulnerability, or in the worst cases, they feign vulnerability.

Again, that’s a covert contract that just simply undermines everything. It becomes one plus one equals two minus one to infinity. Conversely, I think if people can have really hard conversations, this is something I’ve had to work really hard on in recent years, that I’m still working hard on. But the friendship piece seems to be the thing that rises to the top, when I talk to friends who are in these great relationships, it’s like they have so much respect and love and joy in being with their friend. It’s the person that they want to spend as much of their non-working, non-platonic friendship time with, and the person that they want to experience things with and share things with. And it sounds so canned and cliche nowadays, but I think if you step back and examine how most people go about finding a relationship, like, oh, am I attracted? Of course physical attraction is important and other forms of attraction too, and they enter through that portal, which makes sense. That’s the mating dance, that’s the peacock situation. That’s hopefully not the cuttlefish situation.

That’s hopefully not the cuttlefish situation.
But I think that there seems to be a history of people close to me getting into great relationships, where they were friends for a while first or maybe didn’t sleep together right away, that they actually intentionally deferred on that. This has not been my habit or my experience. I’ve gone the more, I think typical, like, oh, there’s an attraction, like this person, there’s an interest. You explore all dimensions of relationship really quickly except perhaps the moving in part and the having kids part, which because it’s a bigger step, harder to undo without more severe consequences. But I think that whole take it slow thing, I don’t think is about getting to know someone slowly, I think it’s about that physical piece, because that does change the nature of the relationship. And I think it’s because it gets right into the more hardwired, primitive circuitry around our feelings of safety, vulnerability.
There’s something about romantic and sexual interactions, where it’s almost like it’s assets and liabilities, right?
Lex Fridman
Mm-hmm.
Mm-hmm.
Andrew Huberman
Where people are trying to figure out how much to engage their time and their energy and multiple people. I’m talking about from both sides, male, female or whatever sides, but where it’s like assets and liabilities. And that’s where it starts getting into those complicated contracts early on, I think. And so maybe that’s why if a really great friendship and admiration is established first, even if people are romantically and sexually attracted to one another, then that piece can be added in a little bit later, in a way that really just seals up the whole thing, and then who knows, maybe they spend 90% of their time having sex. I don’t know. That’s not for me to say or decide obviously, but there’s something there, about staying out of a certain amount of risk of having to engage covert contract in order to protect oneself.

I hear, over and over again, from friends that have made great choices in awesome partners, and have these fantastic relationships for long periods of time, that seem to continue to thrive, at least that’s what they tell me, and that’s what I observe, establish the friendship first and give it a bit of time before sex. And so I think that’s the feeling. That’s the feeling and we’re talking micro features and macro features. And this isn’t about perfection, it’s actually about the imperfections, which is kind of cool. I like quirky people. I like characters.

And this isn’t about perfection, it’s actually about the imperfections, which is kind of cool. I like quirky people. I like characters.
I’ll tell you where I’ve gone badly wrong and where I see other people going badly wrong. There is no rule that says that you have to be attracted to all attractive people, by any means. It’s very important to develop a sense of taste in romantic attractions, I believe. What you really like, in terms of a certain style, a certain way of being, and of course that includes sexuality and sex itself, the verb. But I think it also includes their just general way of being. And when you really adore somebody, you like the way they answer the phone, and when they don’t answer the phone that way, you know something’s off and you want to know. And so I think that the more you can tune up your powers of observation, not looking for things that you like, and the more that stuff just washes over you, the more likely you are to, “Fall in love.” As a mutual friend of ours said to me, “Listen, when it comes to romantic relationships, if it’s not a hundred percent in you, it ain’t happening.”
And I’ve never seen a violation of that statement, where it’s like, yeah, it’s mostly good and they’re this and this, likes the negotiations. Well, already it’s doomed. And that doesn’t mean someone has to be perfect, the relationship has to be perfect, but it’s got to feel hundred percent inside.

There’re very few things like that. I can’t story into building flying cars. I have to actually go do something. And love is also retroactively constructed.

If the other person doesn’t want to be in it, then you shouldn’t be in it. But then missing so many things, and that’s just the attachment machinery, really, at work.

Well, this has been debated for a long time, and I did a four and a half hour episode on fertility. And the reason I did a four and a half hour episode on fertility is that, first of all, I find that reproductive biology be fascinating. And I wanted a resource for people that at were thinking about, or struggling with having kids for whatever reason, and it felt important to me to combine the male and female components in the same episode. It’s all timestamped, so you don’t have to listen to the whole thing. We talk about IVF, in vitro fertilization, we talk about natural pregnancy.

It’s all timestamped, so you don’t have to listen to the whole thing. We talk about IVF, in vitro fertilization, we talk about natural pregnancy.
Okay, the data on position is very interesting, but let me just say a few things. There are a few clinics now, in particular some out of the United States, that are spinning down sperm and finding that they can separate out fractions, as they’re called. They can spin the sperm down at a given speed, and that they’ll separate out at different depths within the test tube, that allow them to pull out the sperm on top or below and bias the probability towards male or female births. It’s not perfect. It’s not a hundred percent. It’s a very costly procedure. It’s still very controversial.
Now with in vitro fertilization, they can extract eggs. You can introduce a sperm, directly by pipette, it’s a process called ICSI. Or you can set up a sperm race in a dish. And if you get a number of different embryos, meaning the eggs get fertilized, duplicate and start form a blastocyst, which is a ball of cells, early embryo, then you can do karyotyping. So you can do look for XX or XY, select the XY, which then would give rise to a male offspring, and then implant that one. So there is that kind of sex selection.
With respect to position, there’s a lot of lore that if the woman is on top or the woman’s on the bottom, or whether or not the penetration is from behind, whether or not it’s going to be male or female offspring. And frankly, the data are not great, as you can imagine, because those-

And there are a lot of other variables that are hard to control. So for instance, if it’s during intermission, during sex penetration, et cetera, then you can’t measure, for instance, sperm volume as opposed to when it’s IVF, and they can actually measure how many milliliters, how many forward motile sperm. It’s hard to control for certain things. And it just can vary between individuals and even from one ejaculation to the next and… Okay, so there’s too many variables; however, the position thing is interesting in the following way, and then I’ll answer whether or not you can bias us towards a female. As long as we’re talking about sexual-

It’s hard to control for certain things. And it just can vary between individuals and even from one ejaculation to the next and… Okay, so there’s too many variables; however, the position thing is interesting in the following way, and then I’ll answer whether or not you can bias us towards a female. As long as we’re talking about sexual-

MDs will say, “That’s crazy.”
But others that I sought out, and not specifically for this answer, but for researching that episode, said that, “Yeah, what you’re talking about is trying to get the maximum number of sperm and it’s contained in semen. And yes, the semen can leak out. And so keeping the pelvis tilted for about 15 degrees for about 15 minutes, obviously tilted in the direction that would have things running upstream, not downstream, so to speak.”
Lex Fridman
Gravity.
Gravity.
Andrew Huberman
Gravity, it’s real. So for maximizing fertilization, the doctors I spoke to just said, “Look, given that if people are trying to get pregnant, what is spending 15 minutes on their back?” This sort of thing. Okay. So then with respect to getting a female offspring or XX female offspring, selectively, there is the idea that as fathers get older, they’re more likely to have daughters as opposed to sons. That’s, from the papers I’ve read, is a significant but still mildly significant result. So with each passing year, this person increases the probability they’re going to have a daughter, not a son. So that’s interesting.

It’s not trivial. It’s not a trivial difference. But if they want to ensure having a daughter, then they should do IVF and select an XX embryo. And when you go through IVF, they genetically screen them for karyotype, which is XX, XY, and they look at mutations, genotypic mutations for things like trisomies and aneuploidies, all the stuff you don’t want.

There’s a lot of variable, but there haven’t been systematic studies. So I think probably the best thing to do, unless they’re going to do IVF, is just roll the dice. And I think with each passing year, they increase the probability of getting a female offspring. But of course, with each passing year, the egg and sperm quality degrade, so get after it soon.

So I went down a rabbit hole. Sexology, there’s journals on sex.
Andrew Huberman
Oh, yeah. Sure. And some of them, not all, quite reputable and some of them really pioneering in the sense that they’ve taken on topics that are considered outside the main frame of what people talk about, but they’re very important. We have episodes coming out soon with, for instance, the Head of Male Urology, Sexual Health and Reproductive Health at Stanford, Michael Eisenberg. But also one with a female urologist, sexual health, reproductive health, Dr. Rena Malik, who has a quite active YouTube presence. She does these really dry, scientific presentation, but very nice. She has a lovely voice. But she’ll be talking about erections or squirting. She does very internet-type content, but she’s a legitimate urologist, reproductive health expert.

She has a lovely voice. But she’ll be talking about erections or squirting. She does very internet-type content, but she’s a legitimate urologist, reproductive health expert.
And in the podcast, we did talk about both male and female orgasm. We talked a lot about sexual function and dysfunction. We talked a lot about pelvic floor. One interesting factoid is that only 3% of sexual dysfunction is hormonal, endocrine, in nature. It’s more often related to some pelvic floor or vasculature, blood flow related or other issue. And then when Eisenberg came on the podcast, he said that far less sexual dysfunction is psychogenic in origin than people believe. That far more of it is pelvic floor, neuro and vascular. It’s not saying that psychogenic dysfunction doesn’t exist, but that a lot of the sexual dysfunction that people assume is related to hormones or that is related to psychogenic issues are related to vascular or neural issues. And the good news is that there are great remedies for those. And so both those episodes detail some of the more salient points around what those remedies are and could be.
One of the, again, factoids, but it was interesting that a lot of people have pelvic floor issues and they think that their pelvic floors are, quote, unquote, messed up. So they go on the internet, they learn about Kegels. And it turns out that some people need Kegels, they need to strengthen their pelvic floor. Guess what? A huge number of people with sexual and urologic dysfunction have pelvic floors that are too tight and Kegels are going to make them far worse, and they actually need to learn to relax their pelvic floor. And so seeing a pelvic floor specialist is important.
I think in the next five, 10 years, we’re going to see a dramatic shift towards more discussion about sexual and reproductive health in a way that acknowledges that, yeah, the clitoris comes from the same origin tissue as the penis. And in many ways the neural innervation of the two, while clearly different, has some overlapping features that there’s going to be discussion around anatomy and hormones and pelvic floors in a way that’s going to erode some of the cloaking of these topics because they’ve been cloaked for a long time and there’s a lot of… Well, let’s just call it what it is. There’s a lot of bullshit out there about what’s what.
Now, the hormonal issues, by the way, just to clarify, can impact desire. So a lot of people who have lack of desire as opposed to lack of anatomical function, this could be male or female that can originate with either things like SSRIs or hormonal issues. And so we talk about that as well. So it’s a pretty vast topic.
Productivity

Yes. We’ve pushed out episodes because I want more time with them. I also, I haven’t advertised this, but I have another fully tenured professor that’s started checking my podcasts and helping me find papers. He’s a close friend of mine. He’s an incredible expert in neuroplasticity and that’s been helpful. But I do all the primary research for the episodes myself. Although my niece has been doing a summer internship with me and finding amazing papers. She did last summer as well. She’s really good at it. Just sick that kid on the internet and she gets great stuff.

Can I ask you, just going on tangents here, what’s the hardest, finding the papers or understanding what a paper is saying?
Andrew Huberman
Finding them. Finding the best papers. Yeah. Because you have to read a bunch of reviews, figure out who’s getting cited, call people in a field, make sure that this is the stuff. I did this episode recently on ketamine. About ketamine, I wasn’t on ketamine. And there’s this whole debate about S versus R ketamine, and SR ketamine. And I called two clinical experts at Stanford. I had a researcher at UCLA help me. Even then, a few people had gripes about it that I don’t think they understood a section that I perhaps could have been clearer about. But yeah, you’re always concerned that people either won’t get it or I won’t be clear. So the researching is mainly about finding the best papers.

But yeah, you’re always concerned that people either won’t get it or I won’t be clear. So the researching is mainly about finding the best papers.
And then I’m looking for papers that establish a thoroughness of understanding. That are interesting, obviously. It’s fun to get occasionally look at some of the odder or more progressive papers that are what’s new in a field and then where there are actionable takeaways to really export those with a lot of thoughtfulness.
Going back to the productivity thing I do, I get up, I look at the sun. I don’t stare at the sun, but I get my sunshine. It all starts with a really good night’s sleep. I think that’s really important to understand. So much so that if I wake up and I don’t feel rested enough, I’ll often do a non-sleep deep rest yoga nidra, or go back to sleep for a little bit, get up, really prioritize the big block of work for the thing that I’m researching. I think a little bit of anxiety and a little bit of concern about deadline helps. Turning the phone off helps, realizing that those peak hours, whenever they are for you, you do not allow those hours to be invaded, unless a nuclear bomb goes off. And nuclear bomb is just a phraseology for, family crisis would be good justification. If there’s an emergency, obviously.
But it’s all about focus. It’s all about focus in the moment. It’s not even so much about how many hours you log. It’s really about focus in the moment. How much total focus can you give to something? And then I like to take walks and think about things and sometimes talk about them in my voice recorder. So I’m just always churning on it, all the time. And then of course, learning to turn it off and engage with people socially and not be podcasting 24 hours a day in your head is key. But I think I love learning and researching and finding those papers and the information, and I love teaching it.
And these days I use a whiteboard before I start. I don’t have any notes, no teleprompter. Then the whiteboard that I use beforehand is to really sculpt out the different elements and the flow, get the flow right and move things around. The whiteboard is such a valuable tool. Then take a couple pictures of that when I’m happy with it, put it down on the desk and these are just bullet points and then just churn through and just churn through. And nothing feels better than researching and sharing information. And I, as you did, grew up writing papers and it’s hard. And I like the friction of, “Uh, can’t. I want to get up. I want to use the bathroom.”
When I was in college, I was trying to make up deficiencies from my lack of attendance in high school, so much so that I would set a timer. I wouldn’t let myself get up to use the bathroom even. Never had an accident. I listened to music, classical music, Rancid, a few other things. Some Bob Dylan maybe thrown in there and just study and just… And then you’d hit the two-hour mark and you’re in pain and then you get up, use the bathroom. You’re like, “That felt so good.” There’s something about the human brain that likes these kind of friction points and working through them and you just have to work through them.
So yeah, I’m productive and my life has arranged around it, and that’s been a bit of a barrier to personal life at times. But my life’s been arranged around it. I’ve set up everything so that I can learn more, teach more, including some of my home life. But I do still watch Chimp Empire. I still got time to watch Chimp Empire. Look, the great Joe Strummer, Clash, they were my favorite Mescaleros. He said, this famous Strummer quote, “No input, no output.” So you need experience. You need outside things in order to foster the process.
But yeah, just nose to the grindstone man, I don’t know. And that’s what I’m happy to do with my life. I don’t think anyone should do that just because. But this is how I’m showing up. And if you don’t like me, then scroll… What do they say? Swipe left, swipe right. I don’t know. I’m not on the apps, the dating apps. So that’s the other thing. I keep waiting for when, “Listens to Lex Fridman podcast,” is a checkbox on Hinge or Bumble or whatever it is. But I don’t even know. Are those their field? I don’t know. What are the apps now?
Lex Fridman
Well, I’ve never used an app and I always found troublesome how little information is provided on apps.

For example, one of the things I’ve really struggled finishing is something that’s in Russian that requires translation and overdub and all that kind of stuff. The other project, I’ve been working on for at least a year off and on, but trying to finish is something we’ve talked about in the past. I’m still on it, project on Hitler in World War II. I’ve written so much about it and I just don’t know why I can’t finish it. I have trouble really… I think I’m terrified being in front of the camera.

Yeah, it was weird. The first year of the podcast, it just spilled out of me. I had all that stuff I was so excited about. I’d been talking to everyone who would listen and even when they’d run away, I’d keep talking before there was ever a camera, wasn’t on social media. 2019, I posted a little bit. 2020, as you know, I started going on podcasts. But yeah, the zest and delight in this stuff. I was like, “Circadian rhythms, I’m going to tell you about this stuff.” I just felt like, here’s the opportunity and just let it burst.

And then as we’ve gotten into topics that are a little bit further away from my home knowledge, I still get super excited about it. This music in the brain episode I’ve been researching for a while now, I’m just so hyped about it. It’s so, so interesting. There’s so many facets. Singing versus improvisational music versus, “I’m listening to music,” versus learning music. It just goes on and on. There’s just so much that’s so interesting. I just can’t get enough. And I think, I don’t know, you put a camera in front of me, I sort of forget about it and I’m just trying to just teach.

Well, the best lecturers, as you know, and you’re a phenomenal lecturer, so you embody this as well, but when I teach at Stanford, I was directing this course in neuroanatomy and neuroscience for medical students. And I noticed that the best lecturers would come in and they’re teaching the material from a place of deep understanding, but they’re also experiencing it as a first time learner at the same time. So it’s just sort of embodying the delight of it, but also the authority over the… Not authority, but the mastery of the material. And it’s really the delight in it that the students are linking onto. And of course they need and deserve the best accurate material, so they have to know what they’re talking about.

And it’s really the delight in it that the students are linking onto. And of course they need and deserve the best accurate material, so they have to know what they’re talking about.
But yeah, just tap into that energy of learning and loving it. And people are along for the ride. I get accused of being long-winded, but things get taken out of context, that leads to greater misunderstanding. And also, listen, I come from a lineage of three dead advisors. Three. All three. So I don’t know when the reaper’s coming for me. I’m doing my best to stay alive a long time. But whether or not it’s a bullet or a bus or cancer or whatever, or just old age, I’m trying to get it all out there as best I can. And if it means you have to hit pause and come back a day or two later, that seems like a reasonable compromise to me. I’m not going to go longer than I need to and I’m trying to shorten them up. But again, that’s kind of how I show up.
It’s like Tim Armstrong would say about writing songs. I asked him, “How often do you write?” Every day. Every day. Does Rick ever stop creating? No. Has Joe ever stopped preparing for comedy? Are you ever stopping to think about world issues and technology and who you can talk to? It seems to me you’ve always got a plan in sight. The thing I love about your podcast the most, to be honest these days, is the surprise of I don’t know who the hell’s going to be there. It’s almost like I get a little nervously excited about when a new episode comes out. I have no idea. No idea. I have some guesses based on what you told me during the break. You’ve got some people where it’s just like, “Whoa, Lex went there? Awesome. Can’t wait.” Click. I think that’s really cool. You’re constantly surprising people. So you’re doing it so well. It’s such a high level and I think it’s also important for people to understand that what you’re doing Lex, there’s no precedent for it. Sure. There’ve been interviews before, there have been podcasts before. There are discussions before. How many of your peers can you look to find out how best to do the content like yours? Zero. There’s one peer: you. And so that should give you great peace and great excitement because you’re a pioneer. You’re literally the tip of the spear.
I don’t want to take an unnecessary tangent, but I think this might thread together two of the things that we’ve been talking about, which are, I think of pretty key importance. One is romantic relationships, and the other is creative process and work. And this again, is something I learned from Rick, but that he and I have gone back and forth on. And that I think is worth elaborating on, which is earlier we were saying the best relationship is going to be one where it brings you peace. I think peace also can be translated to, among other things, lack of distraction. So when you’re with your partner, can you really focus on them and the relationship? Can you not be distracted by things that you’re upset about from their past or from your past with them? And of course the same is true for them, right? They ideally will feel that way towards you too. They can really focus.
Also, when you’re not with them, can you focus on your work? Can you not be worried about whether or not they’re okay because you trust that they’re an adult and they can handle things or they will reach out if they need things? They’re going to communicate their needs like an adult. Not creating messes just to get attention and things like that, or disappearing for that matter. So peace and focus are intimately related, and distraction is the enemy of peace and focus.
So there’s something there, I believe, because with people that have the strong generative drive and want to be productive in their home life, in the sense have a rich family life, partner life, whatever that is, and in their work life, the ability to really drop into the work and you might have that sense like, “I hope they’re okay,” or, “need to check my phone or something,” but just know we’re good.
Lex Fridman
Yeah. Everything’s okay.
Yeah. Everything’s okay.
Andrew Huberman
So peace and focus, I think and being present are so key. And it’s key at every level of romantic relationship, from certainly presence and focus. Everything from sex to listening to raising a family, to tending to the house and in work, it’s absolutely critical. So I think that those things are mirror images of the same thing. And they’re both important reflections of the other. And when work is not going well, then the focus on relationship can suffer and vice versa.

How incredibly wonderful it could be to have a person in your life that enables that creative focus.

Andrew Huberman
Yeah. And you supply the peace and focus for their endeavors, whatever those might be. That symmetry there. Because clearly people have different needs and the need to just really trust, when Lex is working, he’s in his generative mode and I know he’s good. And so then they feel, sure, they’ve contributed to that. But then also what you’re doing is supporting them in whatever way happens to be. And I think that sometimes you’ll see that. People will pair up along creative-creative or musical-musical or computer scientists. But I think, again, going back to this Conti episode on relationships is that the superficial labels are less important, it seems, than just the desire to create that kind of home life and relationship together. And as a consequence, the work mode. And for some people, both people aren’t working and sometimes they are. But I think that’s the good stuff. And I think that’s the big learning in all of it, is that the further along I go, with each birthday, I guarantee you’re going to be like, “What I want is simpler and simpler and harder and harder to create. But oh, so worth it.”

It’s proportional to the love. But yeah, I’ll cry about it right now if I think about it. It wasn’t putting him down, it wasn’t the act of him dying, any of that. Actually, that was a beautiful experience. I didn’t expect it to be, but it was in my place when I was living in Topanga during the pandemic where we launched the podcast and I did it at home and he hated the vet so I did it at home. And he gave out this huge, “Ugh,” right at the end. And I could just tell he had been in not a lot pain, fortunately. But he had just been working so hard just to move at all.

And the craziest thing happened, Lex. It was unbelievable. I’ve never had an experience like this. I expected my heart to break, and I’ve felt a broken heart before. I felt it, frankly, when my parents split, I felt it when Harry shot himself. I felt it when Barbara died and felt it when Ben went as well. And so many friends, way too many friends. The end of 2017, my friend Aaron King, Johnny Fair, John Eikleberry, stomach cancer, suicide, fentanyl. I was like, “Whoa. All in a fricking week.” And I just remember thinking, “What the…?” And it’s just heartbreak and you just carry that and it’s like, “Uh.” And that’s just a short list. And I don’t say that for sob stories. It’s just for a guy that wasn’t in the military or didn’t grow up in the inner city, it’s an unusual number of deaths, close people.
When Costello went, the craziest thing happened. My heart warmed up, it heated up. And I wasn’t on MDMA. The moment he went, it just went whoosh. And I was like, “What the hell is this?” And it was a supernatural experience to me. I just never had that. I put my grandfather on the ground, I was a pallbearer at the funeral. I’ve done that more times than I’d like to have ever done it. And it just heated up with Costello and I thought, “What the fuck is this?”
And it was almost like, and we make up these stories about what it is, but it was almost like he was like, “All right,” I have to be careful because I will cry here and I don’t want to. It was almost like he was like all that effort, because I had been putting so much effort into him, it was like, “All right, you get that back.” It was like the giant freaking, “Thank you.” And it was incredible. And I’m not embarrassed to shed a tear or two about it if I have to.
I was like, “Holy shit.” That’s how close I was to that animal.
Lex Fridman
Where do you think can find that kind of love again?

Andrew Huberman
Man, I don’t know. And excuse me for welling up. I mean, it’s a freaking dog, right? I get it. But for me, it was the first real home I ever had. But when Costello went, it was like we had had this home in Topanga. We had set it up and he was just so happy there. And I think, I don’t know, it was this weird victory slash massive loss. We did it. 11 years. Freaking did everything, everything, to make him as comfortable as possible. And he was super loyal, beautiful animal, but also just funny and fun. And I was like, “I did it.” I gave as much of myself to this being as I felt I could without detracting from the rest of my life. And so I don’t know.

When I think about Barbara especially, I well up and it’s hard for me, but I talked to her before she died and that was a brutal conversation, saying goodbye to someone, especially with kids. And that was hard. I think that really flipped a switch in me where I’m like, I always knew I wanted kids. I’d say, “I want kids. I want a lot of kids.” That flipped a switch in me. I was like, “I want kids. I want my own kids.”
Lex Fridman
You might be able to find that kind of love having kids.

Andrew Huberman
Yeah, I think because it was the caretaking. It wasn’t about what he gave me all that time, and the more I could take care of him and see him happy, the better I felt. It was crazy. I don’t know. So I miss him every day. Every day. I miss him every day.

I think you should absolutely have kids. Look at the people in our life. Because in case you haven’t realized it already, we’re the younger of the podcasters. But like Joe and Peter and Segura and the rest, they’re like the tribal elders and we’re not the youngest in the crew. But if you look at all those guys, they all have kids. They all adore their kids and their kids bring tremendous meaning to their life. We’d be morons if you didn’t go off and start a family, I didn’t start start a family. And yeah, I think that’s the goal. Of the goals, that’s one of them.

The kids not only make their life more joyful and brings love to their life, it’s also makes them more productive, makes them better people, all of that. It’s kind of obvious. Yeah,

You won Alone Season 6, and I think are still considered to be one of, if not the most successful survivor on that show. So let’s go back, let’s look at the big picture. Can you tell me about the show Alone? How does it work?
And then I felt like I got in a zone and I felt like I was right back in Siberia or in that head space. And I found, I actually really enjoyed it. I had been a little bit out of, I guess you call it the game, because I had had a child. And so, when we had our daughter, we came back to the States and then a bunch of things happened, and we didn’t end up going back to Russia, so it’d been a couple of years that I was just, we were raising the little girl and boy then and then-
But I was struck initially with… I actually noticed how mad I was. I was like, “Oh, this is actually…” I was like, “That was awesome though. It was seeing a dinosaur. That was really cool.” And then I was like, “Oh, what an idiot. How’d I miss?” But it made me that much more determined to make it happen again. It was like, “Okay, nobody’s going to make this happen except myself.” You can’t complain. It wouldn’t have done me any good to go back and mope about it. And so then I was like, I had a thought. I was like, “Oh, I remember these native guys telling me they used to build these giant fences and funnel game into certain areas and stuff.” And I was like, “Man, that’s a lot of calories, but I have to make that happen again now.” So I kind of went out there and tried that, and that was kind of an attempt at something to, it could have failed or not worked, but sure enough, it worked and the opportunity came again.
The moose came wandering along and I was able to get it. But being able to take failure the sooner you can, the better. Accept it and then learn from it, it is kind of a muscle you have to exercise a little bit.
And I thought, “You know what? If a bear comes, I’ll probably hear it and I’ll come out and be able to shoot it.” So I went to sleep and I woke up the next morning, I went out and I was like, “Where’s that jug?” And then I was like, “Wait a second. What are all these prints?” And I started looking around and it took a second to dawn on me because I haven’t interacted with wolverines very often in life. And I was like, “Oh, those are wolverine tracks.” And he was just so much sneakier than a bear would’ve been or something. So it kind of surprised me, and he took off with that jug of fat. And so, then I went from feeling pretty good about myself to now I’m losing again against whoever this other person is with a moose. So again, kind of the pressure came back to, “Oh, no, I got to produce again.” It wasn’t the end of the world. And I think they may have exaggerated a little bit how little fat I had left.
I still had… A moose has a lot of fat, but it did make me feel like I was at a disadvantage again. And so, yeah, that was pretty intense because those wolverines, they’re bold little animals and he was basically saying, “No, this is my moose.” And I had to counter his claims.
I couldn’t believe I actually, I was like, “Oh my gosh, I got the moose. I think that was a really good shot.” You get all excited, but then it plays back in your head. And particularly when you’re first learning to hunt, there’s always an animal that gets away and you make a bad decision or not a great shot or something, and it’s just part of it. And so, of course you’re like, “I’m not going to be satisfied until I see this thing.” So I followed the blood trail a little while and I saw some bubbly blood, which meant it was hitting the lungs, which meant it’s not going to live. You’ll get it, as long as you don’t mess it up. And so I went back to my shelter and waited an hour. I skinned that rabbit that had caught and then super nervous the slowest hour ever, ever.
And then I followed it along, ended up losing the blood trail. I was like, “No, no.” And then I was like, “Well, if there’s no blood, I’m just going to follow the path that I would go if I was a moose, the least resistance through the woods.” So I followed kind of along the shore there, and sure enough, I saw him up there and I was like, “Oh, I was so excited.” He laid down, but he hadn’t died yet. And so, he just sat there and he would stand up and I would just like, “No, no, no, no.” And he would lay back down, I’d be like, “Yes.” And then he would stand up, and it was like that for a couple hours it took him. And then finally at one point, and a lot of people have asked, “Why wouldn’t you go finish it off?” So, when an animal like that gets hit, it had no idea what hit it. Just all of a sudden it’s like, “Ah,” something got it, it ran off and it lays down and it’s actually fairly calm and it doesn’t really know what’s going on.
And if you can leave it in that state, it’ll kind of just bleed out and as peacefully as possible. If you go chase after it, that’s when you lose an animal because as soon as it knows it’s being hunted, it gets panicked, adrenaline, and it can just run and run and run, and you’ll never find it. So I didn’t want it to see me. I knew if I tried to get it with another arrow, there’s a chance I could have finished it off, but there’s also a not bad chance that it would see me, take off, or even attack, because moose can be a little dangerous. And so, I just chose to wait it out, and at one point it stood up and fell over and I could tell it had died. And walked over, you actually touch it and you’re just like, “Whoa. No way.”
That whole burden of weeks of, “You’re going to starve, you’re going to starve.” And it got rid of that demon. To be honest, it’s one of the happiest moments of my life. It’s really hard to replicate that joy because it was just so real, so directly connected to your needs. It’s all so simple. It was a peak experience for sure.
Now, when an animal’s kind of walking towards you, if it’s walking towards you but not directly towards you, that’s what you call quartering towards you. And you can picture, it’s actually pretty difficult to hit both lungs because the shoulder blade and all that bone is in the way. So you have to make a perfect shot to get them both. And to be honest, when I took my shot, I was a couple inches or few inches, and so it went through the first lung and then it sunk the arrow all the way into the moose, but it allowed that second lung to stay breathing, which meant the moose stayed alive longer.
I literally know how many a animals year it takes to feed my family and myself. I actually know the exact number and I know what the cost of that is, and I’m aware of it because I’m out in the woods and I see these beautiful elk and moose, and I really love the species, love the animals, but there is a fact that one of those individuals is going to have to feed me. And particularly on Alone, it was very heightened, that experience. So I shot that one animal and I was so, so thankful that I wanted to give that big guy a hug and like, “Hey, sorry, it was you, but had to be somebody.”
It has its senses to defend itself, and you have your wit to try to get over those. And it really becomes, it’s not easy. It becomes kind of that chess game. And, those prey animals are always tuned in. It’s, slightest stick, they’re looking for wolves or for whatever it is. So, there’s something really pure and fun about it. I will say there’s an aspect that is fun. There’s no denying it. It’s like how people have been hunting forever. And I think it speaks to that part of us somehow. And I think bow hunting is probably the most pure form of it, and that you get those experiences more often than with a rifle. So, I don’t know. I enjoy it a lot. And the way they do regulations and such kind of the best times to hunt are usually allowed for bow because they’re trying to keep it fair for the animal and such. So…
And then, once I reassessed, and right away, I saw that there were moose tracks and such. So. I just started to plan for that. I moved my camp into an area that was as removed as I could be from where all the action is, where the tracks were, so that I wasn’t disturbing animal patterns. I made sure the wind, the predominant wind was blowing out my scent to sea or to the water. And then really, to be honest, if you want to actually survive somewhere is different than Alone, but you do have to be active and you’re not going to live… You’re not going to be sustainable by starving it out. You have to unlock the key that is sustainability.
And I think there’s a lot of areas that still have that potential, but you have to figure out what it is. It’s usually going to be a combination of fishing, trapping, and then hunting. And then, once you have the fishing and trapping will get you until you have some success hunting. And then, that’ll buy you three or four months of time to continue, and to keep hunting again. And you just have to roll off of that. But it depends on where you are, what opportunities are there.
But you don’t have to start with that necessarily because you got other needs you got to focus on. That said, you’ll see a lot of people on Alone that really focus on building a log cabin because they want to be secure or incorporating whatever the earth has around, whether it be rocks or whether it be digging a hole. And we’ve seen some really cool shelters, and I’m not going to knock it. Everybody… It is all different strokes for different folks. But my particular idea was to keep it fairly simple, improve it with time, but spend most of my energy… The shelter, you really need to think about it can’t be smoky because that’ll be miserable, but it is nice to have a fire inside. So you need to have a fire inside that’s not going to be dangerous, smoke-free, and then also airtight, because you’re never going to have a warm shelter out there because you don’t have seals and things like that, but as long as the air’s not moving through it, you can have a warm enough shelter.
I think log cabin is great in as a hunting cabin, if you’re going to have something for years. But in a three, six-month scenario, I don’t know that it’s worth the calorie expenditure.
There must be so many of those lakes that people haven’t been to.” It really was a neat area, really remote. And for the show’s purpose, I think it was perfect because it did have enough game and enough different avenues forward that I think it really did reward activity. But it’s a special place. It was Dene, there was a tribe that lived there, the Dene people, which interestingly enough, here’s a side note.
When I was in Siberia, I floated down this river called the Podkamennaya Tunguska, and you get to this village called Sulamai, and there’s these Ket people they’re called, and there’s only 600 of them left. This is in the middle of Siberia, not unlike the Pacific coast, but their language is related to the Dene people. And so, somehow that connection was there thousands of years ago. Super interesting.
But I had that one pretty dialed in. And then, once you have calories, you can stay warm, you can stay active, you got to dress warm. There’s a good one. If you’re in the cold, never let yourself get too cold, because what happens is you’ll stop feeling what’s cold and then frostbite and then issues, and then it’s really hard to warm back up. So, it was so annoying.
I’d be out going to ice fish or something and then I would just notice that my feet are cold and you’re just like, “Oh, dang it.” I just turn around, go back, start a fire, dry my boots out, make sure my feet are warm, and then go again. I wouldn’t ignore that.
It wakes you up. It makes you feel really alive, engaged. It feels like the margins of air are smaller, so you’re alert and engaged a little more. There is something that’s a little bit life-giving just because you feel on an edge, you’re on this edge, but you have to be alert because even some of the natives I lived with, the lady had face issues because she let her head get cold, when they’re on a snowmobile hat was up too high, that little mistake, and then it just freezes this part of your forehead and then the nerves go and then you got issues. One just hat wasn’t high enough, so you got to be dialed in on stuff.
So, you just need to dress warm, the native, all that fur, all that stuff, and then all of a sudden you have your little refuge, have a nice warm fire going in your teepee, and then I bet you could learn to appreciate it.
But then, the flip side of that is you get to feel every moment and you get to feel alive in every moment. So, it’s both scary when you’re inexperienced and beautiful when you are experienced. Were there times when you got hungry?
So, I can say on Alone, I was not that hungry. I’ve definitely been really hungry in Russia. There were times when I lost a lot of weight. I lost a lot more weight in Siberia than I did on Alone.
And definitely it was hard psychologically because I didn’t know when it was going to end. I thought this could go, like I said, six months, it could go eight months, a year, and then you start to… a two and a three-year-old and you start to weigh in the, “Is it worth it if it goes a year and it’s not worth it if it goes eight months and I still lose?” So, I feel like I had this pressure and it was psychologically difficult for that reason. Physically, it wasn’t too bad.
I just thought, but in my head I thought, “If I get today a 130 or 40, even if someone else has big game, I had a pretty good idea they might quit because it would be long, cold, dark days.” And how miserable is that? Just it’s so boring. It’s freezing. And so, I thought the only time I thought I could think about winning is when I got to day 130 or 40.
And I definitely had that with what I had. Now, maybe I would’ve… I probably would’ve gotten more. I had caught that big 20 something pound pike on the last day I was there. Maybe catch some more of those. And I don’t know, I don’t know how many calories I had stored, but I had a lot.
And so, how long would that have lasted me assuming I didn’t get anything else? It definitely would have… I would definitely would’ve reached my goal of a 130 or 40 days. And then, after that I thought we were just going to push into the… then it’s just to see how much who has what reserves and will go as far as we can. And that would get me through January into February. And I just thought, “Man, that’s going to be miserable for people.”
And then, I think things that might, you start thinking about family and this and that in those situations. And I just knew that those… because I had gone to all these trips to Russia for a year at a time, the time context was a little broader for me than I think for some people. Because I knew I could be gone for a year and come back, catch up with my loved ones, bring what I got back, whether that’d be psychological, whatever it is, and we’d all enrich each other.
And once it’s in hindsight, that year would’ve been like that, talking about it. So, I had that perspective. And so, I knew I wasn’t going to tap for any other reason other than running out of food someday. So, that was my stressor.
There was every day I would think of, “I got to think of something to make me laugh and then do some stupid skit.” And then, that would fill a couple hours of my time, and then I’d spend an hour or two, a few hours fishing, and then you’d spend a few hours, whatever you’re doing.
I actually don’t know that. I’ll say that was one of the advantages of being on the show versus in Siberia. So, no, because I didn’t. In Siberia just do skits by myself, but I didn’t film it. And so, it was quite nice to have this camera that made you feel like you weren’t quite as alone as if you were just in the woods by yourself.
And I think for me, I was able to… it was a pain. It was part of the cause of me missing that moose. There’s issues with it, but I just chose to look at it like, this is an awesome opportunity to share with people, a part of me that most people don’t get to see. So, that was, I just chose to look at it that way and it was an advantage because you could do stuff like that.
I wouldn’t do that. I would just probably not hunt. I’d just give up. I’m sure, because even if I had a bunch of food and this and that, but because I knew you… you know you’re a part, you’re sharing, it gives you a lot of strength to go through and having that camera just makes it that much more vivid because you know you’re not just going to be sharing a vague memory, but an actual experience.
Once I got the moose, I could have shot the moose and just not stressed. That would’ve been like… And so, that was a big difference between the seasons that I felt… I mean, I felt like the psychology of season seven, they messed up by doing a hundred-day cap because for my own experience, that was the hardest part. But Roland’s a beast.
Like I said, if I shot a moose and it was a hundred days done, if I shot a moose and you don’t know, it’s like, “Crap, I could still lose to somebody else.” But it’s going to be way in the future. So, anyway, that for me was definitely the hard part.
They’re going to get to 90 and they’re not going to quit at 90, they’re going to go to a 100. I just figured we can’t start thinking about the end until a couple months from when it ended. So, I was just shocked and they tricked me pretty good. They know how to make you think that you’re not alone.
And then, you’ll notice that every forest freeloader in the woods is going to come and try to steal your food. And it was just fun. I mean, it was crazy to watch. It’s all the Jay, all the camp Jays pecking at it. Everything I did, there was something that could get to it. If put on the ground, the mice get on it and they poop on it and they mess it up. So, ultimately it just dawned on me, “Shoot, I’m going to have to build one of those Evenki like food caches. So, I did and I put it up there and I thought I solved my problem. To be honest, the Evenki then, so they would’ve taken a page out of, they would’ve mixed me and Roland’s solution. They build this tall stilt shelter and then put a box on the top that’s enclosed.
And then, the bears can’t get to it, the mice can’t poop on it, the birds, the wolverine, it’s safe. And I never finished it. In hindsight, I don’t actually know why. I think just the way it timed. I didn’t think something was going to get up there.
Then, it did. And then, you’re counting calories and stuff. I should have in hindsight, just boxed it in right away.
I had 28 rabbits or something, but I was losing weight at exactly the same speed as everybody else that didn’t have anything. So, that’s interesting.
So, it gives you a different experience than a lot. But at one point when I was, I guess, yeah, 18, he invited me to come along with him. He’d probably been doing it five or so, four or five years or more. And I said, ” Sure.” So, I quit my job and went out with him.
Hobo Jordan is a bit of an over stuff. I feel self-conscious about that because I rode trains across the country up and down the coast, back, spent the better part of the year run around riding trains and all the staying in places related to that. But all the people, the real hobos, those guys are out there doing it for years on end.
But it was such a… for me, what it felt like was, it felt like a bit of a rite of passage experience, which is missing I think in modern life. So, I did this thing that was a huge unknown. Ben was there with me and my brother for most of it.
We traveled around, got pushed my boundaries in every which way, froze at night and did all this stuff. And then, at the end I actually wanted to go back and go back home. And so, I went on my own and went from Minneapolis back up to Spokane on my own, which was my first stint of time by myself for a week which was interesting.
And that was you wake up, you don’t have a schedule, you literally just have needs and you just somehow have to meet your needs. And so, there’s a really sense of freedom you get that is hard to replicate elsewhere. And so, that was eye-opening to me. And I think once I did that, I went back. So, I went back to my old job at the salad dressing plant.
And there’s this old cross-eyed guy and he was, “Oh, Hobo Jordo is back.” And that’s where I got it. But at freedom always was very important to me, I think from that time on.
And also, a lot of people that support you for traveling. Because there’s a lot of people dream of experiencing that freedom, at least the people I’ve met. And they usually don’t go outside of their little town.
They have a thing and they have a family usually, and they don’t explore, they don’t take the leap. And you can do that when you’re young. I guess you could do that at any moment. Just say fuck it and leap into the abyss of being on the road. But anyway, what did you learn about this country, about the people in this country?
It broadened my horizons for sure, from being just an Idaho kid and then meeting all these different people and just seeing the goodness in people and this and that. It’s also very, a lot of drugs and a lot of people with mental issues that you’re friends with, dealing with and all that kind of stuff.
And he has his own sense of ethics that I think is really interesting because he is super honest, but he expects it of others. And so, it’s funny in the modern context, the thing that pops in my head is when he got a car for the first time, which wasn’t that long, he was in his 30s or something and he registered it, which he was mad about that he had to register. But then, the next year they told him he had to register again and he is like, “What did you lose my registration?” went down there to the DMV, chewed him out that he had to reregister, because he already registered.
Where’s the paperwork? But he just views the world from a different lens. I thought, but on everything, he’s a character. Now, he just lives by digging up bottles and finding treasures in them.
He would bum change. And I’d see him sometimes and I’d be gone and then go to New York to visit my sister or something. And I’d, ” Sure enough, there’s Devo on the street. What do you know?” You go visit him in the hospital because he got bit by 27 hobo spider bites.
It was just always rough, but charismatic, vital, the vitality of life was in him, but it was just so permeated with drugs and alcohol too. It’s interesting.
Doing things that you think like, “Oh, I don’t want to do that. I’m a little scared of that.” I mean, that’s what you got to do. You just get out of your-
Anyway, sure enough, the police stopped the train. Somebody had seen us on it, and they searched it, got us and threw us in jail. It was not a big deal. We were in jail a couple days, but when we got out, of course they put us… We were in some podunk town in Indiana and we didn’t know where to catch out of there. And so, we were at some factory and we just banning factory.
And we were right there for four days, no train that was going slow enough that we could catch. And then, we found this big old roll of aluminum foil, and now I got to apologize to this woman because we were so bored just sitting there. We built these hats, like horns coming out every which way, and loops, and just sitting there. And it was that night and some minivan pulled up to this train that was going by too. We’re like, “Rr-rr-rr.” We were circling the car.
And that brother was about my age. I remember at that time I read this verse that said, “If you’re in the darkness and see no light, just continue following me,” basically. I was like, “Okay, I’m going to take that to the bank even though I don’t know if it’s true or not.” And then, the only glimpse of light I got in all that was when I heard about that orphanage to go build that orphanage.
And I prayed about it and I felt, and I can’t explain, it brought me to tears. I felt so strongly that I should go. And so, I was like, “Well, that’s a clear call. I’m just going to do it.” So, I just bought a ticket, got a visa for a year, and then I went, and helped build an orphanage and we got that built. But he was an American and I wanted to live with the Russians to learn the language.
And so, he sent me to a neighboring village to live with a couple Russian families that needed a hand, somebody to watch their kids, and cut their hay, and milk the cow and all that. So, I found myself in that little Russian village, just getting to know these two guys and their families. It was pretty fascinating. And of course, I didn’t know the language yet and they were two awesome dudes.
Both of them had been in prison, and met each other in prison, and were really close because they found God in prison together, and got out and stayed connected. And so, I’d bounce back between those two families and they used to always tell me about their third buddy they had been in prison with who was a native fur trapper now in the north.
And so, they’d go, “You got to go meet our buddy up north.” And one day that guy came through to sell furs in the city, and he invited me to come live with him, and my visa was about to expire, but I was like, “When I come back, I’ll come.” And so, I went back home, earned some more money and did some construction or whatever. Then, went back and headed north to hang out with Yura and fur trap. And that started a whole new… Opened world that I didn’t know about.
And I’m going to try to express that in my life in whichever way I can and just trust that if I do that, if I act like I… I’ve heard this lately, but if you just act like you believe, over time, that world kind of opens to you. When I said I would go to Russia, I prayed and I was like, “Lord, I don’t see you. I don’t know, but I got this what I felt like was a clear call. I have only one request and that is that you would give me the faith to match my action.”
I’m choosing to believe. I could choose not to because whatever, but I’m going to choose to act and I just ask to have faith someday. And honestly, for the whole first year I went through, that was a very crazy time for me, learning the language, being isolated, being misunderstood, blah-blah, but then trying to approach all that with a loving open heart.
And then, I came back and I realized that that prayer had been answered. That wasn’t the end of my journey, but I was like, “Whoa, that was my deepest request that I could come up with and somehow that had been answered.”
I’m going to be like cut the hay, be the most hardest worker I can be because that’s my goal here. I didn’t have any other agenda or anything except to try to live a life of love and I couldn’t define it beyond that.
It’s a very rich language. I remember there was a comedy act in Russian, but he was saying, “One word you can’t have in English is [foreign language 01:17:32],” meaning I didn’t drink enough to get drunk. That type thing. But it’s just that you can make up these words using different prefixes, and suffixes, and blend them in a way that is quite unique and interesting.
And honestly, would be really good for poetry because it also doesn’t have sentence structure in the same way English does. The words can be jumbled in a way.
And on that program, you talked about how to say I love you in Russian, just hilarious. And it was for me, the first time, I don’t know why you were a great person to articulate the flexibility and the power of the Russian language. That’s really interesting.
And in conversation comes out really interesting kinds of wisdom. When I listen to world leaders that speak Russian speak, and I see the translation, and it loses the irony. In between the words, if you translate them literally, you lose the reference in there to the history of the peoples.
So, they’ll go out, and they’ll go from one cabin, and each cabin will have five or six trap lines going out of it. Every day, it’ll take a half a day to walk to the end of your trap line, open all the traps and a half a day to get back. And they’ll do that. They’ll spend a week at a cabin, open up all the traps, and then it’ll take a day to hike over to the other cabin.
Go to that one, open up all those traps, and then there, and then three weeks later or so, they’ll end up back at the first cabin, and then check all the traps. And so, it’s that rhythm. And they’ll do that for a couple, few months during the winter. And you’re trapping sable, they’re called sable, like Pine Martin is what we would have the equivalent of over here.
And just guess what time it is and follow along. And it takes all day and I kid you not, I ended up a hundred yards from the cabin. I was like, “Whoa, this is the trail and that’s the cabin,” like, “Oh, amazing.” And then, the other time I went out and I was heading over the mountains and I thought hours had passed. I probably had gotten slightly lost, and then I thought I was halfway there.
So, I thought, “Okay, I’m going to sit down and cook some food, get a drink. I’m thirsty.” So, I sat down, and went to start a fire, and my matches had gotten all wet because the snow had fallen on me, and soaked me, and I didn’t have them wrapped in plastic. I was like, “Oh no, I can’t drink water.” So, I was like, “Well, I’m just going to power through.”
I’m halfway there where I kept hiking and then I realized it was getting night. And then, I even realized I was at the halfway point because I saw this rock. I was like, “Oh no, that’s the halfway point.” I was like, “I can’t do this.” And so, I need to go get water. I ended up having to divert down the mountain and head to the water. There was a whole ordeal.
I had to take my skis off because I was going through an old forest fire burn, so they were all really close trees, but then the snow was like this deep. So, I was just trudging through and just wishing a bear would eat me, get it over with. But I finally made it down to the water, chopped a hole through the ice, I was able to take a sip.
He said, “Oh, it sucks.” And you laid down and just fell asleep. I fell asleep and I was like… Oh, that’s funny. The last few weeks that we’ve been apart, who knows what he went through, who knows why he was there at that time at night, all just summarized and it sucked. And we went to sleep, and the next morning we parted ways and who knows what.
I remember that story of that miserable day going down to the ice and I can smile about it now. And now that I know that, I can be in a miserable position and realize that that’s what the outcome will be once it’s over. It’s just going to be a story.
And they were really open and welcoming because their cousin just brought me out there and vouched for me. But it was during fencing season and fencing in Siberia for those reindeer is an incredible thing. You take an axe, you go out and you just build these 30-kilometer loop fences with just logs interlocking. It’s tons of work. And all these guys are more efficient bodies, they’re better at it.
And I’m just working less efficiently and also a lot bigger dude, but we’re all just on the same rations kind of. And I got down that. I was like 155 pounds getting down pretty dang skinny for my 6’3″ frame and just working really hard. And in the spring in Siberia, there’s not much to forage. In the fall, you can have pine nuts and this and that, but in the spring, you’re just stuck with whatever random food you’ve got.
And so, that’s where I lost the most weight, and felt the most hungry, and I had a lot of other issues. I was new to that type of work. And so, working as hard as I could, but also making mistakes, chopping myself with the axe and getting injured, all kinds of stuff.
One is with these Russian heads or the Soviet heads, whatever they had, they’re a little wider on top here. Meaning, you can put the handle through from the top like a tomahawk, and that means you’re not dealing with a wedge. And if it ever loosens and you’re swinging, it only gets tighter. It doesn’t fly off. And so, that’s something that’s cool. What they do that’s unique is, so you can see, this is the wolverine axe. So, it’s got the little wolverine head in honor of the wolverine I fought on the show.
And it makes it really good for that planing. The other thing it is, especially in northern woods, all the trees are like this big. You’re never cutting down a big giant tree. And so, when you swing with a single sided axe like this, sharpen from the one side, with your right-hand swing like this, it really bites into the wood and gives you a… Because with that, if you can picture it, that angle is going to cause deflection.
And without that angle on your right hand and swing, it just bites in there like crazy. And so, that, there’s other little… The handle is made by some Amish guys in Canada. This is all hand forged by-
And so, if I have an axe, I feel always confident that I can get a quick fire in whatever weather and I wouldn’t feel the same without it in that regard. So, that’s the main thing. Of course, you can use it. I use it if you’re taking an animal apart or if you’re… All kinds of, what else? Building a shelter, skinning teepee poles or whatever you’re doing.
I don’t think there’s enough advantages that a saw incurs. With a good axe, you’ll see people with little camp axes, and stuff, and they just don’t think they like axes. It’s like, “Well, you haven’t actually tried to…” Try a good one first and get good with it. The one thing about an axe, they’re dangerous. So, you need to practice, always control it with two hands, make sure you know where it’s going to go.
It doesn’t hit you, or when you’re chopping, like say you’re creating something that you’re not doing it on rocks and stuff so that you’re doing it on top of wood so that when you’re hitting the ground, you’re not dulling your axe. You got to be a little bit thoughtful about it.
And the native guy was like, “Oh, I think there’s a boot we left.” A few years ago, we left a boot four kilometers that way. So, we got the reindeer, took him, rode him over. Sure enough, there’s a stump with a boot upside down, pull it off, put it on. I was like, “Sweet. I’m back in business.” I went back a couple of days later, pting, chum, chopped it, cut your foot, cut my rubber boot.
And I was just like, “Dang it.” And I was mad enough that I just grabbed the axe, and swung it at the tree, and it just one-handed, and deflected off and bam, right into my knee.
So, literally, I knew I was in shock because I’m just going to go back to teepee right now. So, I ran back to teepee, laid down, and honestly, I was stuck there for a few days. I was in so much pain and my other knee was bad. It was rough. I literally couldn’t even walk at all or move. There was a plastic bag, I had to poop in it and roll to the edge of the teepee, shove it under the moss. I just totally immobilized.
And then, you get to that inner dry wood, and then you try to do this maybe under a spruce tree or under your own body so that it’s not getting rained on while you’re doing it. Make a bunch of little curls that’ll catch a flame or light, and then you make a lot more kindling and little pieces of dry wood than you think, because what’ll happen, you’ll light it and it’ll burn through and like, “Dang it.”
So, just be patient, you’re going to be fine. Make a nice pile of curls that you can light or spark and then get a lot of good dry kindling. And then, don’t be afraid to just boom, boom, boom, pile a bunch of wood on and make a big old fire. Get warm as fast as you can. It’s amazing how much that of a recharge it is when you’re cold and wet.
And so, if you can find that in a rainstorm, you can just make a little pile of those shavings, get the crappiest spark or quickest light, and it’ll sit there and burn like a factory fire starter. It’s really, really nice. That’s good to spot. It’s a good thing to keep your eye out for.
And there’s something about the natural rhythms that you are in when you’re that connected to the natural world that really does feel like that’s what we’re designed for. And so, there’s a psychological benefit you gain from spending that much time in that realm. And for that reason, I think that people that are connected to those ways are able to tap into a particular…
I noticed it a lot with the natives. So, if I met the natives in the village, I would think of them as unhappy people. They drink a lot and always fighting. The murder rate is through the roof. The suicide rate’s through the roof. But if you meet those same people out in the woods living that way of life, I thought, these are happy people. And it’s an interesting juxtaposition to be the same person.
But then, I lived in a native village that had the reindeer herding going on around it, and everybody benefited because of that. I also went to a native village that they didn’t hold those ways anymore. And so, everybody was just in the village life. And it just felt like a dark place. Whereas, the other native village, it was rough in the village because everybody drank all the time. But it had that escape… it had that escape valve. And then, once you’re out there, it’s just a whole different world. And it was such an odd juxtaposition.
I will say it’s a little bit different for men than women, because the men are living the dream as far as what I would like. So, you’re hunting and fishing and managing reindeer and you got all these adventures. So, what ends up happening is that a lot more guys than young men out there in the woods. And so, there’s a draw, also, I think, to go to the village probably to find a woman. And then there’s a draw of technology and the new things. But then once they’re there, honestly, alcohol becomes so overwhelming that everything else just fiddles away.
But I felt I knew where my purpose was, I knew what my calling was. I’m just going to do it. And it sounds glamorous now when I talk about it, but it sucked a lot of the times. And it was a lot of loneliness, a lot of giving up what I wanted, a lot of watching people I cared about. You put all this effort in, and then you just see the people that you put all this effort and just die and this and that, because that happened all the time.
And then the other thing I thought I gave up was a relationship because you couldn’t… I wasn’t going to find a partner over there. And so, interestingly enough now in life, I can look back and be like, “Whoa, weird. Those two things I thought I gave up is where I’ve been almost provided for the most in life.” Now, I have this career guiding people in the wilderness that I love. I genuinely love it. I find purpose in it. I know it’s healthy and good for people. And then I have an amazing wife and an amazing family. How did that happen? But I didn’t exactly aim at it. I consciously, in a way, I mean I hoped it was tangential, but I aimed at something else, which was those lessons I got from the Gulag Archipelago.
And during the chaos of World War I, the Ottoman umpire was collapsing and it had all kinds of issues. And one of its issues was it had a big minority group and it thought it would be a good time to get rid of it. And they can justify it in all the ways you can, like, there’s some people that were rebelling or this or that, but ultimately, it was just a big collective guilt and extermination policy against the Armenians and the Assyrians.
And my grandparents, my grandma was 13 at the time, and my grandpa was 17, which is interesting. It happened almost 100 years ago, but my dad was born when my grandma was pretty old. But my grandmother, her dad was taken out to be shot. The Turks were coming in and rounding up all the men, and they took them out to be shot. And then they took my grandma and her. She had seven brothers and sisters and her mom. And they drove her out into the desert, basically.
Her dad got taken out to be shot. So, his name was Shaman Yumara, whatever, took him out. They were all tied up, all shot, needs to say a quick prayer before they shot him. But he fell down and he found he wasn’t hit. And usually, of course, they’d come up and stab everybody or finish them off, but there was some kind of an alarm, and all the soldiers rushed off and he found himself in the bodies and was able to untie himself. They were naked and hungry and all that.
And he ran out there, escaped, went into a building and found the loaf of bread wrapped in a shirt and was able to escape, fled. He never saw his family for… so, to continue the story, my grandma got taken with her mother and brothers and sisters. They just drove them into the desert until they died, basically, and run them around in circles and this and that, and then all the raping and pillaging that accompanies it.
And at one point, her mom had the baby and the baby died. And her mom just collapsed and said, “I just can’t go any further.” And my grandma and her sister picked her up to, “We got to keep going,” and picked her up. They left the baby along with the other. Everybody else had died. It was just the three of them left.
And somehow, they bumbled across this British military camp and were rescued. Neither of the sister nor my great-grandmother ever really recovered, from what I understand, but my grandma did. At the same time, in another village in Iran there, the Turks came in and were burning down my grandpa’s village and they caught. And my grandpa’s dad was in a wheelchair and he had some money belt and he stuffed all his money in it and gave it to grandpa and just told him to run and don’t turn back. And they came in the front door as he was running out the back, and he never saw his dad again. But he turned around and saw the house on fire, never knew what happened to his sister. And so, he was just alone. He ran.
At some point, I can’t remember, he lost his money belt and he took his jacket off, forgot it was something happened. Anyway, so he was in a refugee camp. He ended up getting taken in by some Jesuit missionary. So, anyway, both of them had lost basically everything. And then, at some point, they met in Baghdad, started a family, immigrated to France. And then it just so happened to be right before World War II.
And so, the Nazis invaded. My aunt, she’s still alive, but she actually met a resistance fighter for the French under a bridge somewhere. And they fell in love, and she got married. So, she had an inn on the French resistance at one point. And of course, they were all hungry. They’d recently immigrated, but also had this Nazi occupation and all that. And so, Uncle Joe, the resistance fighter guy, told him, like, “Hey, we’re going to storm this noodle factory, come.” And so, they stormed the noodle factory and all my aunts surrounding there and we’re throwing out noodles into wheelbarrows and everybody was running.
And then the Nazis came back and took it back over and shot a bunch of people and everything. And grandpa, he had already come from where he came from, was paranoid. So, he buried all the noodles out in the garden. And then my two aunts got stuck in that factory overnight with all the Nazi guards or whatever. And then the Nazi guards went all from house to house to find everybody that had had noodles and punish them. But they didn’t find my grandpa’s, fortunately. They searched his house, but not the garden.
So, they had noodles. And somehow, it must’ve been in the same factory or something, but olive oil, and they just lived off of that for all the whole war years. My aunts ended up getting out of the… they hid behind boxes and crates overnight and stuff, and the resistance stormed again in the morning and they got away and stuff. But anyway, chaos. So, when they moved to America, I will say, the most patriotic family everywhere ever, they loved it. It was paradise here.
So, I recognized it again in my dad. My dad went through a really slow painful decline in his health. And he had diabetes, ended up losing one leg. And so, he lost his job. He had to watch my mom go to school. All he wanted to do was be a provider and be a family man. I bet the best time in his life was when his kids ran to him and gave him a hug. But then, all of a sudden, he found himself in a position where he couldn’t work and he had to watch his wife go to school, which was really hard for her, and become the breadwinner for the family. And he just felt a failure. And I watched him go through that.
After all these years of letting that foot heal, we went out first day and we were splitting firewood with the splitter. And he was just, ” So good to be back out, Jordan. It’s so nice.” And he crushed his foot in the log splitter and you’re just like, “No.” And so, then they just amputated it. We’ve got both legs amputated, and then his health continued to decline. He lost his movement in his hands. So, he was incapacitated, to a degree, and in a lot of pain. I would hear him at night in pain all the time.
And I delayed a trip back to Russia and just stayed with my dad for those last six months. And it was so interesting, having had lost everything. I’ve watched him wrestle with it through the years, but then he found his joy and his purpose just in being almost, I mean, a vegetable. I’d have to help him pee, roll him onto the cot, take him to dialysis. But we would laugh. I’d hear him at night crying or in pain, like, “Ah.” And then in the morning he’d have encouraging words to say.
And I was like, “Wow, that’s how you face loss and suffering.” And he must’ve gotten that somehow from his parents. And then I find myself on this show, and I had a thought, “Why is this easy to me,” in a way? “Why is this thing that’s…” and it just felt like this gift that had handed down and now would be my duty to hand down. But it’s an interesting…
That said, a lot of that gets wrapped up in what is so natural. It just becomes another instrument for tribalism or another justification for wrong. And so, I even myself, am self-conscious sometimes talking about matters of faith, because I know when I’m talking about something else than what someone else might think of when they hear me talking about it. So, it’s interesting.
But then, at times, I would try to picture them, and I couldn’t quite picture the kids, but I could feel the love. And then I started asking all the deepest existential questions I could, and it felt like I was just one answer, another answer, another answer. Everything was being answered. And I felt like I was communing with God, whatever you want to say.
But I was very aware of the fact that that communing was just peeling back the tiniest corner of the infinite, and it just dumped me with every answer I felt I could have. And it blew me away. So, then I asked it, “Well, if You’re the infinite, why did You reveal to me yourself? Why did You use the story of Jesus to reveal yourself?” And then that infinite amorphous thing had to, somehow, take form for us to be able to relate to it. It had to have some kind of a form. But whenever you create a form out of something, you’re boxing it in and subjugating it to boundaries and stuff like that. And then that subject to pain and subject to the brokenness and all that.
And I was like, “Oh, wow.” But when I had that thought, then, all of a sudden, I could relate my dark hands on the chains to the rest of the experience, and then all of a sudden I could picture my children as the children rather than this amorphous feeling of love. It was like, “Oh, there’s Alana and Alta and Zion.” But then they were bounded, and then once they’re bounded, you’re subject to the death and to the misunderstanding and to all that. I picture the amoeba or the cell, and then when it dies, it turns into a unformed thing.
So, we need some kind of form to relate to. So, instead of always just talking about God completely and tangibly, it gave me a way to relate to it. And I was like, “Wow, that was really powerful to me,” and putting it in a context that was applicable.
But placing that in front of you as the ideal is so important to put a check on your human instincts, on your tribalism, on your… I mean, very quickly, like we were talking about with evil, it can really quickly take its place in your life, you almost won’t observe it happening. And so, I much appreciate all the me striving. I grew up in a Christian family, so I had these cliches that I didn’t really understand, like a relationship with God, what does that mean?
But then I realized, when I struggled with trying, with taking… I actually did try to take it seriously and struggle with what does it mean to live out of life of love in the world? But that’s a wrestling match. It’s not that simple. It sounds good, but it’s really hard to do. And then you realize you can’t do it perfectly. But in that struggle, in that wrestling match is where I actually sense that relationship. And then that’s where it gains life and how that… and I’m sure that relates to what Jordan Peterson is getting at in his metaphor.
And the hard part about it’s you don’t know. You don’t always have the clarity using reason to understand what is good and what is right and what is wrong. You have to live it with humility and constantly struggle. Because then, yeah, you might wake up on a society where you’re committing genocides and you think you’re the good guys. And I think you have to have the courage to realize you’re not. It’s not always obvious.
One thing I noticed about the natives who live with those animals all the time is they relate to life and death a little more naturally. We feel really removed from it, particularly in urban settings. And I think when you interact with animals, and you have to confront the life and the death of them and the responsibility of a symbiotic relationship you have, I think it opens it a little bit awareness to your place in the puzzle, and puts you in it rather than above it.
And he and my friend, were going to go on this fishing trip, and so was I. And I was just like, “I might just stay.” And I was in this little Russian village and they’re like, “All right, well.” [inaudible 02:20:57] was like, “Man, I had a buddy that died doing that with diesel a couple of years ago. Man.”
So anyway, I made my way to the hospital, and by then you’re really out of it. And they put me in this little dark room. It almost sounds unrealistic, but it’s exactly how it happened. They put me in a little room with a toilet, and they gave me a galvanized bucket, and then they just had a cold water faucet and they’re just like, “Just chug water, puke into the toilet, and just flush your system as much you can.” But they only had a cold water faucet. So I was just sitting there like chug, chug, chug, until you puke, and chug until you puke, and I’m in the dark. And I started to shiver, because I was so cold, but I just had to still get this thing up to me and chug until I puked. I was picturing, I remember reading about the Japanese torture where they would put a hose in somebody and then make them drink water until they puke.
Anyway, and I just felt so… The only way I can express it, I felt so possessed, demon possessed. I was just permeated with gas. I could feel it was coming out of my pores, and I wanted to rip it out of me and I couldn’t. I’d puke into the toilet and then couldn’t see, but I was wondering if it was rain.
And then I just remember, I could tell I was going out pretty soon, and I remember looking at my hands up close. I’d see them a little bit and I was like, “Oh, that’s how dad’s hands looked.” They were alive, alive, and then interesting. Are my hands going to look like that and a few minutes or whatever.
So then I wrote down to my family what I thought, “I love you all. I feel at peace,” blah, blah, blah. And then I passed out and I woke up. But I didn’t think… I actually thought, when I went to pass out, I thought there was a coin toss for me. So I really felt like I was confronting the end there.
Would I be able to endure that? I would have at least a legacy to look back on of people who did, but god forbid I ever have to delve that deep. You know what I mean? I could see that breaking somebody.
So if I hadn’t been able to procure food, and I was starving to death, it’s like, okay, I’m going to go home. But if you put yourself in that situation, but it’s not a game show, and having been there to some degree, I will say I wasn’t even close. I don’t even know. It hadn’t pushed my mental limit at all yet I would say or on the scale, but that’s not to say there isn’t one. I know there is one, but I have a hard time…
I know I’ve dealt with enough pain and enough discomfort in life that I know I can deal with that. I think it gets difficult when there’s a way out, and you start to wonder if you shouldn’t take the way out as far as if there’s no way out, I don’t know-
But if you’re in a situation and you don’t have the option to quit, is knowing that you’re doing permanent, that’s not going to break. That won’t break me. You just have to get through it. I’m not sure what my mental limit would be outside of the family suffering in the way that I described earlier.
And again, that was something I saw in dad that was interesting. How can you find joy in that when you’re just steeped in that all the time? And people, I’m sure listening, there’s a lot of people that do, and talk about the cross to bear, and the hero journey to be good for you for trying to find your way through that.
There was a lady in Russia, Tanya, and she had cancer and recovered, but always had a pounding headache, and she was really joyful, and really fun to be around. And I’m just like, man, you just have to have a really bad headache for today to know how much that throws a wrench in your existence. So all that to say if you’re not right now suffering with blindness or a bad back, it’s like just count your blessings because it’s amazing how complex we are, how well our bodies work. And when they go out of whack, it can be very overwhelming. And they all will at some point. And so that’s an interesting thing to think ahead on how you’re going to confront it. It does keeps you humble, like you said.
I had a lot of those thoughts while I was out there, and it was so interesting to see what you would just brush over and confront it. Because in our modern world, when you’re always distracted, you’re just never ever going to know until you take the time to be alone for a considerable amount of time.
And you see beauty and then you start to see the beauty in the smaller scale like, “Look at that little meadow that it’s got an orange, and a pink, and a blue flower right next to each other. That’s super cool.” And there’s a million things like that.
And then plan to go overnight. Don’t be so afraid of all the potentialities that you delay it inevitably. It’s actually one of the things that I’ve enjoyed the most about guiding people, is giving them the tools so that now they have this ability into the future. You can go out and feel like, “I’m going to pick this spot on the map and go there.” And that’s a tool in your toolkit of life that is I think really valuable, because I think everybody should spend some time in nature. I think it’s been pretty proven healthy.
So we have so much now, which should lead us to be hopeful while we try to improve, because there’s definitely a lot of things wrong. But I guess there’s a lot of room for improvement, and I do feel like we’re sort of walking on a knife’s edge, but I guess that’s the way it is.
And now, let me try a new thing where I try to articulate some things I’ve been thinking about, whether prompted by one of your questions or just in general. If you’d like to submit a question including in audio and video form, go to lexfridman.com/ama.
Now allow me to comment on the attempted assassination of Donald Trump on July 13th. First, as I’ve posted online, wishing Donald Trump good health after an assassination attempt is not a partisan statement. It’s a human statement. And I’m sorry if some of you want to categorize me and other people into blue and red bins. Perhaps you do it because it’s easier to hate than to understand. In this case it shouldn’t matter. But let me say once again that I am not right-wing nor left-wing. I’m not partisan. I make up my mind one issue at a time, and I try to approach everyone and every idea with empathy and with an open mind. I have and will continue to have many long-form conversations with people both on the left and the right.
Now onto the much more important point, the attempted assassination of Donald Trump should serve as a reminder that history can turn on a single moment. World War I started with the assassination of Archduke Franz Ferdinand. And just like that, one moment in history on June 18th, 1914 led to the death of 20 million people, half of whom were civilians.
If one of the bullets on July 13th had a slightly different trajectory, where Donald Trump would end up dying in that small town in Pennsylvania, history would write a new dramatic chapter, the contents of which all the so-called experts and pundits would not be able to predict. It very well could have led to a civil war, because the true depth of the division in the country is unknown. We only see the surface turmoil on social media and so on. And it is events like the assassination of Archduke Franz Ferdinand where we as a human species get to find out what the truth is of where people really stand.
The task then is to try and make our society maximally resilient and robust as such to stabilizing events. The way to do that, I think, is to properly identify the threat, the enemy. It’s not the left or the right that are the “enemy,” extreme division itself is the enemy.
Some division is productive. It’s how we develop good ideas and policies, but too much leads to the spread of resentment and hate that can boil over into destruction on a global scale. So we must absolutely avoid the slide into extreme division. There are many ways to do this, and perhaps it’s a discussion for another time. But at the very basic level, let’s continuously try to turn down the temperature of the partisan bickering and more often celebrate our obvious common humanity.
Now let me also comment on conspiracy theories. I’ve been hearing a lot of those recently. I think they play an important role in society. They ask questions that serve as a check on power and corruption of centralized institutions. The way to answer the questions raised by conspiracy theories is not by dismissing them with arrogance and feigned ignorance, but with transparency and accountability.
In this particular case, the obvious question that needs an honest answer is, why did the Secret Service fail so terribly in protecting the former president? The story we’re supposed to believe is that a 20-year-old untrained loner was able to outsmart the Secret Service by finding the optimal location on a roof for a shot on Trump from 130 yards away, even though the Secret Service snipers spotted him on the roof 20 minutes before the shooting and did nothing about it.
This looks really shady to everyone. Why does it take so long to get to a full accounting of the truth of what happened? And why is the reporting of the truth concealed by corporate government speak? Cut the bullshit. What happened? Who fucked up and why? That’s what we need to know. That’s the beginning of transparency.
And yes, the director of the US Secret Service should probably step down or be fired by the president, and not as part of some political circus that I’m sure is coming. But as a step towards uniting an increasingly divided and cynical nation.
Conspiracy theories are not noise, even when they’re false. They are a signal that some shady, corrupt, secret bullshit is being done by those trying to hold on to power. Not always, but often. Transparency is the answer here, not secrecy.
If we don’t do these things, we leave ourselves vulnerable to singular moments that turn the tides of history. Empires do fall, civil wars do break out, and tear apart the fabric of societies. This is a great nation, the most successful collective human experiment in the history of earth. And letting ourselves become extremely divided risks destroying all of that.
So please ignore the political pundits, the political grifters, clickbait media, outrage fueling politicians on the right and the left who try to divide us. We’re not so divided. We’re in this together. As I’ve said many times before, I love you all.
This is a long comment. I’m hoping not to do comments this long in the future and hoping to do many more. So I’ll leave it here for today, but I’ll try to answer questions and make comments on every episode. If you would like to submit questions, like I mentioned, including audio and video form, go to lexfridman.com/ama, and now let leave you with some words from Ralph Waldo Emerson, ” Adopt the pace of nature. Her secret is patience.” Thank you for listening and hope to see you next time.

Introduction
Lex Fridman
The following is a conversation with Jordan Jonas, winner of Alone Season 6, a show where the task is to survive alone in the arctic wilderness longer than anyone else. He is widely considered to be one of, if not the greatest competitors on that show. He has a fascinating life story that took him from a farm in Idaho and hoboing on trains across America to traveling with tribes in Siberia. All that helped make him into a world-class explorer, survivor, hunter, wilderness guide, and most importantly, a great human being with a big heart and a big smile. This was a truly fun and fascinating conversation. Let me also mention that at the end, after the episode, I’ll start answering some questions and we’ll try to articulate my thinking on some top-of-mind topics. So, if that’s of interest to you, keep listening after the episode is over. This is The Lex Fridman Podcast. Support it. Please check out our sponsors in the description. And now, dear friends, here’s Jordan Jonas.

Alone Season 6
You won Alone Season 6, and I think are still considered to be one of, if not the most successful survivor on that show. So let’s go back, let’s look at the big picture. Can you tell me about the show Alone? How does it work?
Jordan Jonas
Yeah. It’s a show where they take 10 individuals and each person gets 10 items off of the list. Basic items would be an axe, a saw, a frying pan, some pretty basic stuff. And then, they send them all, drop them off all in the woods with a few cameras. And so, the people are actually alone. There’s not a crew or anything, and then you basically live there as long as you can. And so, the person that lasts the longest, once the second place person taps out, they come and get you, and that individual wins. So, it’s a pretty legit challenge. They drop you off, helicopter flies out, and you’re not going to get your next meal until you make it happen. So…

Lex Fridman
You have to figure out the shelter, you have to figure out the source of food, and then it gets colder and colder because I guess they drop you out in a moment where it’s going into the winter.

Jordan Jonas
Yeah, they typically do it in temperate, colder climates, things like that. And they start in September, October, so time’s ticking when they drop you off. And yeah, the pressure’s on. You get overwhelmed with all the things you have to do right away. Like, oh man, I’m not going to eat again until I actually shoot or catch something. Got to build a shelter. It’s pretty overwhelming. Figure your whole location out, but it’s interesting, because once you’re there, a little while, you get into a… Well, at least for me it did, there was a week, or maybe not a week, but that I was kind of a little more annoyed with things. It’s like, “Oh, my site sucks,” and then you kind of accept it. You know what it is, what it is. No code, no amount of complaining is going to do anybody any good, so I’m just going to make it happen or do my best to.

And then I felt like I got in a zone and I felt like I was right back in Siberia or in that head space. And I found, I actually really enjoyed it. I had been a little bit out of, I guess you call it the game, because I had had a child. And so, when we had our daughter, we came back to the States and then a bunch of things happened, and we didn’t end up going back to Russia, so it’d been a couple of years that I was just, we were raising the little girl and boy then and then-
Lex Fridman
So you’d gotten a little soft.

But then it was fun after just some days there I was like, “Oh man, I feel like I’m at home now.” And then, it was like you’re kind of in that flow state, and it was-

Actually, there’s a few moments when you left the ladder up or with the moose that you kind of screwed up a little bit.

Jordan Jonas
Oh, yeah.
Oh, yeah.
Lex Fridman
How do you go from that moment of frustration to the moment of acceptance?
How do you go from that moment of frustration to the moment of acceptance?
Jordan Jonas
I mean, the more you put yourself in life in positions that are kind of outside your comfort zone or push your abilities, the more often you’re going to screw up, and then the more opportunity you have to learn from that. And then to be honest, it’s kind of funny, but you almost get to a position where you don’t feel that… It’s not unexpected. You kind of expect you’re going to mess up here and there. I remember particularly with the moose, the first moose I saw, I had a great shot at it, but I had a hard time judging distance because it was in a mud flat, which means it’s hard to tell yardage because you usually typically go and by trees or markers and be like, “Oh, I’m probably 30 yards away.” This was a giant moose and he was 40 something yards away, and I estimated that he was 30 something yards away. So I was way off and shot and dropped between his legs. And then I realized I had not grabbed my quiver, so I only had one shot, and I just watched him turn around and walk off.

So I was way off and shot and dropped between his legs. And then I realized I had not grabbed my quiver, so I only had one shot, and I just watched him turn around and walk off.
But I was struck initially with… I actually noticed how mad I was. I was like, “Oh, this is actually…” I was like, “That was awesome though. It was seeing a dinosaur. That was really cool.” And then I was like, “Oh, what an idiot. How’d I miss?” But it made me that much more determined to make it happen again. It was like, “Okay, nobody’s going to make this happen except myself.” You can’t complain. It wouldn’t have done me any good to go back and mope about it. And so then I was like, I had a thought. I was like, “Oh, I remember these native guys telling me they used to build these giant fences and funnel game into certain areas and stuff.” And I was like, “Man, that’s a lot of calories, but I have to make that happen again now.” So I kind of went out there and tried that, and that was kind of an attempt at something to, it could have failed or not worked, but sure enough, it worked and the opportunity came again.
The moose came wandering along and I was able to get it. But being able to take failure the sooner you can, the better. Accept it and then learn from it, it is kind of a muscle you have to exercise a little bit.
Lex Fridman
Well, it’s interesting because in this case, the cost of failure is like you’re not going to be able to eat.
Well, it’s interesting because in this case, the cost of failure is like you’re not going to be able to eat.
Jordan Jonas
Yeah, that was really interesting. I mean, the most interesting thing about that show was how high the stakes felt because it didn’t feel… You didn’t tell yourself you’re on a show, at least I didn’t. You just felt like you’re going to starve to death if you don’t make this happen. And so the stakes felt so high, and it was an interesting thing to tap into because, I mean, so many of our ancestors probably all just dealt with that on a regular basis, but it’s something that with all the modern amenities and such, and food security that we don’t deal with. And it was interesting to tap into what a kind of peak mental experience that is when you really, really need something to survive, and then it happens. You can’t imagine, I mean, that’s what all our dopamine and receptors are tuned for that experience in particular. So yeah, it was pretty awesome. But the pressure felt very on. I always felt the pressure of providing or starving.

And then there’s the situation when you left the ladder up and you needed fat, and what is it? Wolverine need some of the fat.

Jordan Jonas
Right, yeah. Well, it was… When I got the moose, I was so happy. The most joy, I could almost experience, max, maxed out, but I didn’t think I won at that point. I never thought like, “Oh, that’s my ticket to victory.” I thought, “Holy crap, it’s going to be me against somebody else that gets a moose now, and we’re going to be here six, eight months. Who knows how long? And so, I can’t be here six, eight months and still lose. So I’ve got to outproduce somebody else with a moose.” So I had all that in my head, and I already was of course pretty thin. And so, I was just like, “Man, if somebody else gets a moose, I’m still going to be behind. “And so everything felt precious to me, and I had found a plastic jug, and I put a whole bunch of the moose’s fat in this plastic jug and set it up on a little shelf.

And I thought, “You know what? If a bear comes, I’ll probably hear it and I’ll come out and be able to shoot it.” So I went to sleep and I woke up the next morning, I went out and I was like, “Where’s that jug?” And then I was like, “Wait a second. What are all these prints?” And I started looking around and it took a second to dawn on me because I haven’t interacted with wolverines very often in life. And I was like, “Oh, those are wolverine tracks.” And he was just so much sneakier than a bear would’ve been or something. So it kind of surprised me, and he took off with that jug of fat. And so, then I went from feeling pretty good about myself to now I’m losing again against whoever this other person is with a moose. So again, kind of the pressure came back to, “Oh, no, I got to produce again.” It wasn’t the end of the world. And I think they may have exaggerated a little bit how little fat I had left.
I still had… A moose has a lot of fat, but it did make me feel like I was at a disadvantage again. And so, yeah, that was pretty intense because those wolverines, they’re bold little animals and he was basically saying, “No, this is my moose.” And I had to counter his claims.
Lex Fridman
Well, yeah, they’re really, really smart. They figure out a way to get to places really effectively. Wolverines are fascinating in that way. So, let’s go to that happy moment, the moose. You are the first and one of the only contestants to have ever killed a moose on the show, a big game animal, with a bow and arrow. So this is day 20, so can you take me through the kill?

Jordan Jonas
Yeah. So I had missed one, and I just decided I’m not here to starve, I’m here to try to become sustainable. So I was like, “I don’t care if it’s a risk, I’m going to build that fence.” I built it. I would just pick berries and call moose every day. And it was actually really pleasant, just sit in a berry patch and call moose. But then I also had this whole trap and snare line set out everywhere. So I had all these… I was getting rabbits, and when I was actually taking a rabbit out of a snare when I heard a clank because I had set up kind of an alarm system with string and cans. So…

Lex Fridman
It’s a brilliant idea.
It’s a brilliant idea.
Jordan Jonas
Yeah. Another thing that could have not worked, but it worked and it came through, and I was like, “Oh,” I heard the cans clink. And I was like, “No way.” And so I ran over, I didn’t know what it was exactly, but something was coming along the fence. And I ran over and jumped in the bush next to the funneled exit on the fence. And sure enough, the big moose came running up and your heart gets pounding like crazy. You’re just like, “No way. No way.” I probably could have waited a little longer and had a perfect broadside shot, but I took the shot when he was pretty close, like 24 yards, but he was quartering towards me, which makes it a little harder to make a perfect kill shot. And so, I hit it and it took off running, and I just thought, I was super excited.
Yeah. Another thing that could have not worked, but it worked and it came through, and I was like, “Oh,” I heard the cans clink.

And so, I hit it and it took off running, and I just thought, I was super excited.
I couldn’t believe I actually, I was like, “Oh my gosh, I got the moose. I think that was a really good shot.” You get all excited, but then it plays back in your head. And particularly when you’re first learning to hunt, there’s always an animal that gets away and you make a bad decision or not a great shot or something, and it’s just part of it. And so, of course you’re like, “I’m not going to be satisfied until I see this thing.” So I followed the blood trail a little while and I saw some bubbly blood, which meant it was hitting the lungs, which meant it’s not going to live. You’ll get it, as long as you don’t mess it up. And so I went back to my shelter and waited an hour. I skinned that rabbit that had caught and then super nervous the slowest hour ever, ever.
And then I followed it along, ended up losing the blood trail. I was like, “No, no.” And then I was like, “Well, if there’s no blood, I’m just going to follow the path that I would go if I was a moose, the least resistance through the woods.” So I followed kind of along the shore there, and sure enough, I saw him up there and I was like, “Oh, I was so excited.” He laid down, but he hadn’t died yet. And so, he just sat there and he would stand up and I would just like, “No, no, no, no.” And he would lay back down, I’d be like, “Yes.” And then he would stand up, and it was like that for a couple hours it took him. And then finally at one point, and a lot of people have asked, “Why wouldn’t you go finish it off?” So, when an animal like that gets hit, it had no idea what hit it. Just all of a sudden it’s like, “Ah,” something got it, it ran off and it lays down and it’s actually fairly calm and it doesn’t really know what’s going on.
And if you can leave it in that state, it’ll kind of just bleed out and as peacefully as possible. If you go chase after it, that’s when you lose an animal because as soon as it knows it’s being hunted, it gets panicked, adrenaline, and it can just run and run and run, and you’ll never find it. So I didn’t want it to see me. I knew if I tried to get it with another arrow, there’s a chance I could have finished it off, but there’s also a not bad chance that it would see me, take off, or even attack, because moose can be a little dangerous. And so, I just chose to wait it out, and at one point it stood up and fell over and I could tell it had died. And walked over, you actually touch it and you’re just like, “Whoa. No way.”
That whole burden of weeks of, “You’re going to starve, you’re going to starve.” And it got rid of that demon. To be honest, it’s one of the happiest moments of my life. It’s really hard to replicate that joy because it was just so real, so directly connected to your needs. It’s all so simple. It was a peak experience for sure.
Lex Fridman
And were you worried that it would take many more hours and it would take it into the night?
And were you worried that it would take many more hours and it would take it into the night?
Jordan Jonas
Yeah, I was. Until you actually have your hands on it, I was worried the whole time. It’s a pretty nerve wracking period there between when you get it and when you actually recover the animal, get your hands on it. So, it took longer than I wanted, but I finally got it.

Lex Fridman
Can you actually speak to the kill shot itself, just for people who don’t hunt? What it takes to stay calm, to not freak out too much, to wait, but not wait too long?
Can you actually speak to the kill shot itself, just for people who don’t hunt? What it takes to stay calm, to not freak out too much, to wait, but not wait too long?
Jordan Jonas
Yeah. Yeah. I mean, another thing about hunting is that for every animal, you probably don’t get nine or 10 that just turned the wrong way when you were drawn back or went away behind a tree or you never had a clean shot or whatever it is. And so, every time you can see a moment coming, your heart really starts beating and you have to breathe through it. I can almost feel the nervousness of it. And then, you just try to stay calm. Whatever you do, just try to stay calm, wait for it to come up, draw back. You’ve practiced shooting a lot, so you have kind of a technique. I am going to go back, touch my face, draw my elbow tight, and then the arrow’s going to let loose.

So muscle memory, mostly.
So muscle memory, mostly.
Jordan Jonas
It’s kind of muscle memory. You have a little trigger like, draw that elbow tight, and then it happens, and then you just watch the arrow and see where it goes. Now with the animal, you try to do it ethically. That is, make as good of a shot as you can, make sure it is either hit in the heart or both lungs. And when that happens, it’s a pretty quick death, which is, death is a part of life, but honestly, for a wild animal, that’s probably the best way to go they could have.

And when that happens, it’s a pretty quick death, which is, death is a part of life, but honestly, for a wild animal, that’s probably the best way to go they could have.
Now, when an animal’s kind of walking towards you, if it’s walking towards you but not directly towards you, that’s what you call quartering towards you. And you can picture, it’s actually pretty difficult to hit both lungs because the shoulder blade and all that bone is in the way. So you have to make a perfect shot to get them both. And to be honest, when I took my shot, I was a couple inches or few inches, and so it went through the first lung and then it sunk the arrow all the way into the moose, but it allowed that second lung to stay breathing, which meant the moose stayed alive longer.
Lex Fridman
What’s your relationship with the animal in the situation like that? You said death is a part of life.
What’s your relationship with the animal in the situation like that? You said death is a part of life.
Jordan Jonas
Yeah, that’s an interesting thought because no matter what your relationship to, however you choose to go through life, whatever you eat, whatever you do, death is a part of life. Every animal that’s out there is living off of a dead, even plants, we’re all part of this ecosystem. I think it’s really easy in a, particularly in an urban environment, but anywhere to think that we’re separate from the ecosystem, but we are very much a part of it, whether it be farming requires all this habitat to be turned into growing soybeans and da-da-da. And when you get the plows and the combines, you’re losing all kinds of different animals and all kind of potential habitat. So, it’s not cost-free. And so when you realize that, then you want to produce the food and the things you need in an ethical manner. So, for me, hunting plays a really major role in that.

I literally know how many a animals year it takes to feed my family and myself. I actually know the exact number and I know what the cost of that is, and I’m aware of it because I’m out in the woods and I see these beautiful elk and moose, and I really love the species, love the animals, but there is a fact that one of those individuals is going to have to feed me. And particularly on Alone, it was very heightened, that experience. So I shot that one animal and I was so, so thankful that I wanted to give that big guy a hug and like, “Hey, sorry, it was you, but had to be somebody.”
Lex Fridman
Yeah, there’s that picture of you just almost hugging it.
Yeah, there’s that picture of you just almost hugging it.
Jordan Jonas
Right? Totally.

And you can also think about it, the calories, the protein, the fat, all of that, that comes from that, that will feed you.

What about the bow and arrow perspective?
What about the bow and arrow perspective?
Jordan Jonas
Well, when you hunt with a bow, you just get so much more up close to the animals. You can’t just get it from 600 yards away, you actually have to sneak in within 30 or so yards. And when you do that, the experiences you have are just, they’re way more dragged out. So your heart’s beating longer, you have to control your nerves longer. More often than not, it doesn’t go your way and the thing gets away and you’ve been hiking around in the woods for a week and then your opportunity arises and floats away. No, but at the same time, that’s the only time when you’ll really have those interactions with the animals where you got this bugling bull tearing at the trees right in front of you and other cow and elk and animals running around. You end up having really, I don’t know if I say intimate experiences with the animal, just because you’re in it, you’re kind of in its world, you’re playing its game.

It has its senses to defend itself, and you have your wit to try to get over those. And it really becomes, it’s not easy. It becomes kind of that chess game. And, those prey animals are always tuned in. It’s, slightest stick, they’re looking for wolves or for whatever it is. So, there’s something really pure and fun about it. I will say there’s an aspect that is fun. There’s no denying it. It’s like how people have been hunting forever. And I think it speaks to that part of us somehow. And I think bow hunting is probably the most pure form of it, and that you get those experiences more often than with a rifle. So, I don’t know. I enjoy it a lot. And the way they do regulations and such kind of the best times to hunt are usually allowed for bow because they’re trying to keep it fair for the animal and such. So…
Lex Fridman
So the distance, the close distance makes you more in touch with sort of the natural way of the predator and prey, and you just-

How’d you learn to shoot the bow?
How’d you learn to shoot the bow?
Jordan Jonas
So yeah, I didn’t grow up hunting. I grew up in an area that a lot of people hunted, but my dad wasn’t really into it. And so I never got into it until I lived in Russia with the natives. It was just such a part of everything we did and a part of our life that when I came back, I got a bow and I started doing archery in Virginia. It was a pretty easy way to hunt because the deer were overpopulated and you could get these urban archery permits. So you go out and every couple of days you’d have an opportunity to shoot a deer that they needed population control. And so, there were a lot of them, and it gave you a lot of opportunities to learn quickly. So that’s what got me into it, and then I found I really enjoyed it.

Do you practice with the target also or just practice out?
Do you practice with the target also or just practice out?
Jordan Jonas
Oh, no, I would definitely practice with a target a lot. Again, you kind of have an obligation to do your best because you don’t want to be flinging arrows into the leg of an animal. And it’s a cool way, honestly, to provide quality meat for the family. It’s all raised naturally and wild and free until you bring it home into the freezer. So…

So if we step back, what are the 10 items you brought and what’s actually the challenge of figuring out which items to bring?
Jordan Jonas
Yeah. The challenge is that you don’t exactly know what your site’s opportunities are going to be. So, you don’t really know, should I bring a fishing net? Am I going to even have a spot to net or not? And things like that. I brought an ax, a saw, a Leatherman wave, ferro rod is like, makes sparks to start a fire, a frying pan, a sleeping bag, a fishing kit, a bow and arrow, trapping wire, and paracord. And so, those are my 10 items.

Jordan Jonas
No major regrets. I took the saw kind of, I thought it would be more of a calorie saver, then I didn’t really need it. In hindsight, if I was doing season seven instead of six and got to watch, I would’ve taken the net because I just planned to make a net, but I would’ve rather just had two nets, brought one and left the saw. Because in the northern woods in particular, every tree is the size of your arm or leg. You can chop it down with an ax in a-

The snare wire was good. I ran some, I put out… I used all my snare wire. I ran trap line, which is just a series of traps through the woods and brush every place you see a sign, put a snare, put a little mark on the tree so I knew where that snare was and just make these paths through the woods. And I put out, I don’t know how many, 150, 200 snares. So every day I’d get a rabbit or two out of them. And then, so I had a lot of rabbits, but once I got the moose, I actually took all those snares down because I didn’t want to catch anything needlessly. And, you come to find out you can’t live off of rabbits, man cannot live off rabbit alone it turns out.

You have to be really adaptable because everything’s going to, it’s always going to look different, your situation, your location. I actually had what I thought was a pretty good plan going into Alone, and the location didn’t allow for what I thought it would.

Lex Fridman
What was the plan?
What was the plan?
Jordan Jonas
Well, I thought I would just catch a bunch of fish because I’m on a really good fishing lake. I catch a whole bunch of fish and let them rot for a little while and then just drag them all through the woods into a big pile and then hunt a bear on that big fish pile. That was the plan, and I thought… But when I got there for one, I had a hard time catching fish off the bat, they didn’t come like I was hoping. And then for two, it had burned prior, so there were no berries. And so, there were very few berries, which meant there weren’t grouse, there weren’t bear. They had all gone to other places where the berries were. And so, what I had grown accustomed to relying on in Siberia wasn’t there. So in Russia, which was a similar environment, it was just grouse and berries and fish, and grouse and berries and fish. And then occasionally, you get a moose or something. But I had to reassess, which was part of me being grumpy at the start like, “This place sucks.”

But I had to reassess, which was part of me being grumpy at the start like, “This place sucks.”
And then, once I reassessed, and right away, I saw that there were moose tracks and such. So. I just started to plan for that. I moved my camp into an area that was as removed as I could be from where all the action is, where the tracks were, so that I wasn’t disturbing animal patterns. I made sure the wind, the predominant wind was blowing out my scent to sea or to the water. And then really, to be honest, if you want to actually survive somewhere is different than Alone, but you do have to be active and you’re not going to live… You’re not going to be sustainable by starving it out. You have to unlock the key that is sustainability.
And I think there’s a lot of areas that still have that potential, but you have to figure out what it is. It’s usually going to be a combination of fishing, trapping, and then hunting. And then, once you have the fishing and trapping will get you until you have some success hunting. And then, that’ll buy you three or four months of time to continue, and to keep hunting again. And you just have to roll off of that. But it depends on where you are, what opportunities are there.
Lex Fridman
Okay, so that’s the process. Fishing and trapping until you’re successful hunting. And then the successful hunt buys you some more time.

And then you just go year round like that. And that’s how people did it forever. The pressure, I noticed it with you got that moose and then you’re happy for a week or so, and then you start to be like, “This is finite. I’m going to have to do this again.” And you imagine if you had a family that was going to starve if you weren’t successful this next time. And there’s just always that pressure. It made me really appreciate what people had to deal with.

One thing about wilderness life in general is it’s remarkably less scheduled than anything we deal with. Schedules are fairly unique to the modern context. You’d wake up and you have a confluence of things you want to do, things you need to do, things you should do, and you just kind of tackle them as you see fit as it flows in. And that’s actually one of the things that people really, that I really appreciate about that lifestyle is it really is, you’re kind of in that flow. And so, I’d wake up and be like, “Maybe I’ll go fishing,” and then I’d wander over and fish, and then I’d be like, “I’m going to go check the trap line,” at every day, if I had five or 10 snares, you’re constantly adding to your productive potential, but nothing’s really scheduled. You’re just kind of flying by the seat of your pants.

If you’re dropped off and this is all new to you, of course, all those things are going to be things you have to really think through and plan. When you’re thinking about a shelter, you have to think of, “Oh, here’s a nice flat spot. That’s a good place.” But also, “Is there firewood nearby? And if I’m going to be here for months, is there enough firewood that I’m not going to be walking half a mile to get a dry piece of wood? Is the water nearby? Is it somewhat open but also protected from the elements?” Sometimes you get a beautiful spot. It is great on a calm day, and then the wind comes like. And so. There’s all these factors even down to taking in what game is doing in the area also, and how that relates to where your shelter is.

To see it. Yeah, you want to be, yeah, right. And so, ideally, it depends. You’re always going to make give and takes. And one thing with shelters and location selection and stuff, that’s another thing. You just have to trust your ability to adapt in that situation because everybody has a particular… You got an idea of a shelter you’re going to build, but then you get there and maybe there’s a good cliff that you can incorporate, and then you just become creative. And that’s a really fun process, too, to just allow your creativity to try to flourish in it.

There’s all kinds of philosophies and shelters, which is fun. It’s fun to see people try different things. Mine was fairly basic for the simple reason that I had lived through winters in Siberia in a teepee. So I knew I didn’t need anything too robust. As long as I had calories, I’d be warm. And I wasn’t particularly worried about the cold, but you’ll see. So I kept my shelter really pretty simple with the idea that I built a simple A-frame type shelter. And then, most of my energy is going to be focused on getting calories. And then, of course, there’s always going to be downtime. And in that downtime, I can tweak, modify, improve my shelter. And that’ll just be a constant process that by the time you’re there a few months, you’ll have all the kinks worked out. It’ll be a really nice little setup.

And that’ll just be a constant process that by the time you’re there a few months, you’ll have all the kinks worked out. It’ll be a really nice little setup.
But you don’t have to start with that necessarily because you got other needs you got to focus on. That said, you’ll see a lot of people on Alone that really focus on building a log cabin because they want to be secure or incorporating whatever the earth has around, whether it be rocks or whether it be digging a hole. And we’ve seen some really cool shelters, and I’m not going to knock it. Everybody… It is all different strokes for different folks. But my particular idea was to keep it fairly simple, improve it with time, but spend most of my energy… The shelter, you really need to think about it can’t be smoky because that’ll be miserable, but it is nice to have a fire inside. So you need to have a fire inside that’s not going to be dangerous, smoke-free, and then also airtight, because you’re never going to have a warm shelter out there because you don’t have seals and things like that, but as long as the air’s not moving through it, you can have a warm enough shelter.

Lex Fridman
Oh, really?
Oh, really?
Jordan Jonas
Yeah, it’s a fun thing to do. It works well. Take a little hole, start stacking rocks around it, make sure there’s opening and it actually works. So that’s not as hard as you might think. For me, where I was, I kind of came up with it as I was there with my A-frame. I hadn’t built an A-frame shelter like that before. And so, when I built it, and then I had put a bunch of tin cans in the ground so that air would get the fire, so it was fed by air, which helps create a draft. But, I realized in an A-frame, it really doesn’t… The smoke doesn’t go out very well. Even if you leave a hole at the top, it collects and billows back down. So then I cut some of my tarp and made this, and cut a hole in the…

Jordan Jonas
Cut some of my tarp and made this… and cut a hole in the A-frame, and then I made a hood vent that I could pull down and catch the smoke with. And so, while the fire was going, it would just billow out the hood vent. And then, when it was done burning and was just hot coals, I could close it, seal it up and keep the heat in. So, it actually worked pretty well.

I was wondering, the log cabin, it feels like that’s a thing that takes a huge amount of work before it’ll work?

Jordan Jonas
Right. The difference between a log cabin and a warm log cabin is like an immense amount of work and all the chinking and all the door sealing and the chimney has to be… Anyway, otherwise it’s just going to be the same ambient temperature as outside. So, I don’t think a loan is the proper context for a log cabin.

I think log cabin is great in as a hunting cabin, if you’re going to have something for years. But in a three, six-month scenario, I don’t know that it’s worth the calorie expenditure.
Lex Fridman
And it is a lot of calories. But that’s an interesting metaphor of just get something that works. You see a lot of this with companies, like successful companies, they get a prototype, get a system that’s working and improve fast in response to the conditions to environment.

Can you just speak to the place you were, the Canadian Arctic? It looked cold.
Can you just speak to the place you were, the Canadian Arctic? It looked cold.
Jordan Jonas
Yeah, we were right near the Arctic Circle. I don’t know, it was like 60 kilometers south of the Arctic Circle. It’s a really cool area, really remote. Thousands of little lakes. When you fly over, you’re just like, “Man, that’s incredible.
Yeah, we were right near the Arctic Circle. I don’t know, it was like 60 kilometers south of the Arctic Circle. It’s a really cool area, really remote. Thousands of little lakes. When you fly over, you’re just like, “Man, that’s incredible.
There must be so many of those lakes that people haven’t been to.” It really was a neat area, really remote. And for the show’s purpose, I think it was perfect because it did have enough game and enough different avenues forward that I think it really did reward activity. But it’s a special place. It was Dene, there was a tribe that lived there, the Dene people, which interestingly enough, here’s a side note.
When I was in Siberia, I floated down this river called the Podkamennaya Tunguska, and you get to this village called Sulamai, and there’s these Ket people they’re called, and there’s only 600 of them left. This is in the middle of Siberia, not unlike the Pacific coast, but their language is related to the Dene people. And so, somehow that connection was there thousands of years ago. Super interesting.
Lex Fridman
Yeah. So, language travels somehow.
Yeah. So, language travels somehow.

Within language, it contains a history of a people, and it’s interesting how that evolves over time and how wars tell the story. Language tells the story of conflict and conflict shapes language, and we get the result of that.

And the barriers that language creates is also the thing that leads to wars and misunderstandings and all this kind of stuff. It’s a fascinating tension. But it got cold there, right? It got real cold.

Jordan Jonas
Yeah. I mean, I don’t know. I didn’t have a thermometer. I imagine it probably got to negative 30 at the most. I think it might have gotten… It would’ve definitely gotten colder had we stayed longer. But yeah, to be honest, I never felt cold out there.

But I had that one pretty dialed in. And then, once you have calories, you can stay warm, you can stay active, you got to dress warm. There’s a good one. If you’re in the cold, never let yourself get too cold, because what happens is you’ll stop feeling what’s cold and then frostbite and then issues, and then it’s really hard to warm back up. So, it was so annoying.
I’d be out going to ice fish or something and then I would just notice that my feet are cold and you’re just like, “Oh, dang it.” I just turn around, go back, start a fire, dry my boots out, make sure my feet are warm, and then go again. I wouldn’t ignore that.
Lex Fridman
Oh, so you want to be able to feel the cold?
Oh, so you want to be able to feel the cold?

Yeah, you want to make sure you’re still feeling things and that you’re not toughen through it. Because you can’t really tough through the cold. It’ll just get you.

It wakes you up. It makes you feel really alive, engaged. It feels like the margins of air are smaller, so you’re alert and engaged a little more. There is something that’s a little bit life-giving just because you feel on an edge, you’re on this edge, but you have to be alert because even some of the natives I lived with, the lady had face issues because she let her head get cold, when they’re on a snowmobile hat was up too high, that little mistake, and then it just freezes this part of your forehead and then the nerves go and then you got issues. One just hat wasn’t high enough, so you got to be dialed in on stuff.
Lex Fridman
Well, there’s a psychological element to just… I mean, it’s unpleasant. If I were to think of what kind of unpleasant would I choose, fasting for long periods of time was going without food in a warm environment is way more pleasant than-

Yeah. Okay. Well, there you go. I wonder if that’s… I wonder if you’re born with that or if that’s developed maybe your time in Siberia or do you gravitate towards it? I wonder what that is because I really don’t like survival in the cold.

Jordan Jonas
I think a little bit of it is learned. You almost learned not… you learn not to fear it. You learn to appreciate it. And a big part of that is to be honest, it’s like dressing warm, being in good… it’s not like, there’s no secrets to that. You just can’t beat the cold.

So, you just need to dress warm, the native, all that fur, all that stuff, and then all of a sudden you have your little refuge, have a nice warm fire going in your teepee, and then I bet you could learn to appreciate it.
Lex Fridman
Yeah, I think some of it is just opening yourself up to the possibility that there’s something enjoyable about it. Here I run in Austin all the time in a hundred-degree heat. And I go out there with a smile on my face and learn to enjoy it.

A 100%. I mean, you’re right. It does make you feel alive. Maybe that’s a thing that I struggle with is the time passes slower. It does make you feel alive, you get to feel time.
But then, the flip side of that is you get to feel every moment and you get to feel alive in every moment. So, it’s both scary when you’re inexperienced and beautiful when you are experienced. Were there times when you got hungry?
Jordan Jonas
I got shot a rabbit on day one and I snared a couple rabbits on day two and then more and more as the time went. So, I actually did pretty well on the food front. The other thing is when you have all those berries around and stuff, you do have an ability to fill your stomach, and so you don’t really notice if you’re getting thinner or if you’re losing weight.

So, I can say on Alone, I was not that hungry. I’ve definitely been really hungry in Russia. There were times when I lost a lot of weight. I lost a lot more weight in Siberia than I did on Alone.

I always thought in hindsight, again, when I was out there, I never let myself think you might way, and I just was going to be out there as long as I could and tried to remain pessimistic about it. But I remember a thought that I was like, “I wonder if they’re going to be able to make this look hard.” I did have that thought at one point because it went pretty well.

But I remember a thought that I was like, “I wonder if they’re going to be able to make this look hard.” I did have that thought at one point because it went pretty well.
And definitely it was hard psychologically because I didn’t know when it was going to end. I thought this could go, like I said, six months, it could go eight months, a year, and then you start to… a two and a three-year-old and you start to weigh in the, “Is it worth it if it goes a year and it’s not worth it if it goes eight months and I still lose?” So, I feel like I had this pressure and it was psychologically difficult for that reason. Physically, it wasn’t too bad.
Lex Fridman
This is off mic. We’re talking about Gordon Ryan competing in Jiu-Jitsu. And maybe that’s the challenge he also has to face is to make things look hard. Because he’s so dominant in the sport that in terms of the drama and the entertainment of the sport, in this case of survival, it has to be difficult.

And I’ll add that for sure though, that it’s the woods, it’s nature. You never know how it’s going to go. You know what I mean? It’s like every time you’re out there, it’s a different scenario. So, whatever. Hallelujah, it went well.

When I left, I weighed what I do right now. So, I just weighed my normal weight. I had a couple hundred pounds of moose. I had at least a hundred pounds of fish. I had a pile of rabbits, a wolverine, I had all of this stuff and I hadn’t gotten cold yet.
When I left, I weighed what I do right now. So, I just weighed my normal weight. I had a couple hundred pounds of moose. I had at least a hundred pounds of fish. I had a pile of rabbits, a wolverine, I had all of this stuff and I hadn’t gotten cold yet.
I just thought, but in my head I thought, “If I get today a 130 or 40, even if someone else has big game, I had a pretty good idea they might quit because it would be long, cold, dark days.” And how miserable is that? Just it’s so boring. It’s freezing. And so, I thought the only time I thought I could think about winning is when I got to day 130 or 40.
And I definitely had that with what I had. Now, maybe I would’ve… I probably would’ve gotten more. I had caught that big 20 something pound pike on the last day I was there. Maybe catch some more of those. And I don’t know, I don’t know how many calories I had stored, but I had a lot.
And so, how long would that have lasted me assuming I didn’t get anything else? It definitely would have… I would definitely would’ve reached my goal of a 130 or 40 days. And then, after that I thought we were just going to push into the… then it’s just to see how much who has what reserves and will go as far as we can. And that would get me through January into February. And I just thought, “Man, that’s going to be miserable for people.”
Lex Fridman
And you were like, “I can last through.”
And you were like, “I can last through.”
Jordan Jonas
And I knew I could do it. Yeah.

What aspect of that is miserable?

The hardest thing for me would’ve been the boredom because it’s hard to stay busy when it’s all dark out. When the ice is three, four foot thick, you can’t fish. And I just think it would’ve just been really boring. It would’ve had to been a real Zen master to push through it. But because I had experienced it some degree, I knew I could.

And then, I think things that might, you start thinking about family and this and that in those situations. And I just knew that those… because I had gone to all these trips to Russia for a year at a time, the time context was a little broader for me than I think for some people. Because I knew I could be gone for a year and come back, catch up with my loved ones, bring what I got back, whether that’d be psychological, whatever it is, and we’d all enrich each other.
And once it’s in hindsight, that year would’ve been like that, talking about it. So, I had that perspective. And so, I knew I wasn’t going to tap for any other reason other than running out of food someday. So, that was my stressor.
Lex Fridman
So, you’re able to, given the boredom, given them loneliness, zoom out and accept the passing of time, just let it pass?

For me, I’m going to fairly act. I like to be active, and so I would try to think of creative ways to keep my brain busy. We saw the dumb rabbit for skit, but then I did a whole bunch of elaborate Normandy, reinvasion, invasion enactments and stuff.

There was every day I would think of, “I got to think of something to make me laugh and then do some stupid skit.” And then, that would fill a couple hours of my time, and then I’d spend an hour or two, a few hours fishing, and then you’d spend a few hours, whatever you’re doing.
Lex Fridman
Would you do that without a camera?
Would you do that without a camera?
Jordan Jonas
Yeah. Oh no. The skits, funny question. That’s a good question. I don’t know.
Yeah. Oh no. The skits, funny question. That’s a good question. I don’t know.
I actually don’t know that. I’ll say that was one of the advantages of being on the show versus in Siberia. So, no, because I didn’t. In Siberia just do skits by myself, but I didn’t film it. And so, it was quite nice to have this camera that made you feel like you weren’t quite as alone as if you were just in the woods by yourself.
And I think for me, I was able to… it was a pain. It was part of the cause of me missing that moose. There’s issues with it, but I just chose to look at it like, this is an awesome opportunity to share with people, a part of me that most people don’t get to see. So, that was, I just chose to look at it that way and it was an advantage because you could do stuff like that.
Lex Fridman
I think there’s actual power to doing this kind of documenting, like talking to a camera or an audio recorder. That’s an actual tool in survival because I had a little bit of an experience of being out alone in the jungle and just being able to talk to a thing is much less lonely.

I wouldn’t do that. I would just probably not hunt. I’d just give up. I’m sure, because even if I had a bunch of food and this and that, but because I knew you… you know you’re a part, you’re sharing, it gives you a lot of strength to go through and having that camera just makes it that much more vivid because you know you’re not just going to be sharing a vague memory, but an actual experience.

But if I knew I was the last person on earth, I don’t know that I would even bother. But now, if that was for real, would I bother? That’s the question.

Also, if you are indeed the last person you might want to be documenting it for once you die, an alien species comes about because whatever happened on earth is a pretty special thing. And if you’re the last one, you might be the last person to tell the story of what happened. And so, that’s going to be a way to convince yourself that this is important. And so, the days will go by like this, but it would be lonely. Boy would that be lonely.

That’s one of the reasons I was looking forward to talking to you. Things I appreciate about you is you’re always not out of naivety, but you’re always choose to look at the positive. You know what I mean? And I think that’s a powerful mindset to have appreciated.

Jordan Jonas
If you want to get me the competitive side of it, I would just say, “Well, I’m pretty dang sure I had more pounds of food.” And I didn’t have the advantage in knowing when it would end, which I think would’ve been a great psychological. It would’ve made it really easy.

Once I got the moose, I could have shot the moose and just not stressed. That would’ve been like… And so, that was a big difference between the seasons that I felt… I mean, I felt like the psychology of season seven, they messed up by doing a hundred-day cap because for my own experience, that was the hardest part. But Roland’s a beast.
Lex Fridman
So, for people who don’t know, they put a hundred-day cap on. So, it’s whoever can survive a hundred days for that season. It’s interesting to hear that for you, the uncertainty not knowing when it ends.

I didn’t know how to ration my food. I didn’t know if I was going to lose after six months and then it was all going to be for not. I didn’t know. There’s so many unknowns. You don’t know.

Like I said, if I shot a moose and it was a hundred days done, if I shot a moose and you don’t know, it’s like, “Crap, I could still lose to somebody else.” But it’s going to be way in the future. So, anyway, that for me was definitely the hard part.
Lex Fridman
When you found out that you won and your wife was there, it was funny because you were really happy, there was great moment of you reuniting. But also, there’s a state of shock of you look like you were ready to go much longer.

Jordan Jonas
That was the most genuine shock I could have. I hadn’t even entertained the thought yet. I didn’t even think it was… you’d hear the helicopters and I just assumed there was other people out there. I just hadn’t… I thought, and for one, the previous person that had gone the longest had gone 89 days. So, I just knew whoever else was out here with me, somebody’s got that in their crosshairs.

They’re going to get to 90 and they’re not going to quit at 90, they’re going to go to a 100. I just figured we can’t start thinking about the end until a couple months from when it ended. So, I was just shocked and they tricked me pretty good. They know how to make you think that you’re not alone.

No, I think that would be… then you see that on some of the people do that. For myself that would be bad psychology because then you’re just always disappointing yourself. You have to be resettled with the fact that this is going to go a long time and suck. Once you come to peace with that, maybe you’ll be pleasantly surprised, but you’re not going to be constantly disappointed.

Yeah. So, I was having three good meals a day, and then I’d cook up some meat and go to sleep and then wake up in the middle of the night because there’s long nights and have some meat at night, eat a bunch at night. So, I’d usually have a fish stew for lunch and then moose for breakfast and dinner and then have some for a nighttime snack. Because the nights were long, so you’d be in bed 14 hours and wake up and eat and you dink around and go back to sleep.

Is it okay that it was pretty low-carb situation?
Jordan Jonas
Yeah, I actually felt really good. I think I would’ve felt better if I would’ve had a higher percentage of fat because it’s still more protein than if you’re on a keto diet, you want a lot of fat. And so, I didn’t try to mix in nature’s carbs, different reindeer lichen and things like that. But honestly, I felt pretty good on that diet. We’ll see.

What’s the secret to protecting food? What are the different ways to protect food?
What’s the secret to protecting food? What are the different ways to protect food?
Jordan Jonas
Yeah. There’s a lot of times in a typical situation in the woods hunting, you’ll raise it up in a tree, in a bag, put it in a game bag so the birds can’t peck at it and hang it in a tree. So, that it cools. You got to make sure first to cool it because it’ll spoil. So, you cool it by whatever means necessary, hanging it in a cool place, letting the air blow around it.

So, that it cools. You got to make sure first to cool it because it’ll spoil. So, you cool it by whatever means necessary, hanging it in a cool place, letting the air blow around it.
And then, you’ll notice that every forest freeloader in the woods is going to come and try to steal your food. And it was just fun. I mean, it was crazy to watch. It’s all the Jay, all the camp Jays pecking at it. Everything I did, there was something that could get to it. If put on the ground, the mice get on it and they poop on it and they mess it up. So, ultimately it just dawned on me, “Shoot, I’m going to have to build one of those Evenki like food caches. So, I did and I put it up there and I thought I solved my problem. To be honest, the Evenki then, so they would’ve taken a page out of, they would’ve mixed me and Roland’s solution. They build this tall stilt shelter and then put a box on the top that’s enclosed.
And then, the bears can’t get to it, the mice can’t poop on it, the birds, the wolverine, it’s safe. And I never finished it. In hindsight, I don’t actually know why. I think just the way it timed. I didn’t think something was going to get up there.
Then, it did. And then, you’re counting calories and stuff. I should have in hindsight, just boxed it in right away.

Is a rabbit starvation a real thing?
Is a rabbit starvation a real thing?
Jordan Jonas
Yeah. So, you can’t just live off protein and rabbits are almost just protein. I’d kill a rabbit, eat the innards and the brain and the eyes, and then everything else is just protein. And so, it takes more calories to process that protein than you’re getting from it without the fat. So, you actually lose… I had a lot of rabbits in the first 20 days.

I had 28 rabbits or something, but I was losing weight at exactly the same speed as everybody else that didn’t have anything. So, that’s interesting.
Lex Fridman
That’s fascinating.
That’s fascinating.
Jordan Jonas
And I’d never tried that before. So, I was wondering if I’m catching a ton of rabbits, I wonder if I can last, what, six months on rabbits? But no, you just starve as fast as everybody else. So, I had to learn that on the fly and adjust.

Freight trains

Let’s step to the early days of Jordan. So, your Instagram handles Hobo Jordo. So, early on in your life you hoboed around the US on freight trains. What’s the story behind that?
Jordan Jonas
My brother, when he was 17 or so, he just decided to go hitchhiking and he hitchhiked down to Reno from Idaho where we were and ended up loving traveling, but hated being dependent on other people. So, he ended up jumping on a freight train and just did it. Honestly, he pretty much got on a train and traveled the country for the next eight years on trains, lived in the streets and everywhere, but he was sober.

So, he ended up jumping on a freight train and just did it. Honestly, he pretty much got on a train and traveled the country for the next eight years on trains, lived in the streets and everywhere, but he was sober.
So, it gives you a different experience than a lot. But at one point when I was, I guess, yeah, 18, he invited me to come along with him. He’d probably been doing it five or so, four or five years or more. And I said, ” Sure.” So, I quit my job and went out with him.
Hobo Jordan is a bit of an over stuff. I feel self-conscious about that because I rode trains across the country up and down the coast, back, spent the better part of the year run around riding trains and all the staying in places related to that. But all the people, the real hobos, those guys are out there doing it for years on end.
But it was such a… for me, what it felt like was, it felt like a bit of a rite of passage experience, which is missing I think in modern life. So, I did this thing that was a huge unknown. Ben was there with me and my brother for most of it.
We traveled around, got pushed my boundaries in every which way, froze at night and did all this stuff. And then, at the end I actually wanted to go back and go back home. And so, I went on my own and went from Minneapolis back up to Spokane on my own, which was my first stint of time by myself for a week which was interesting.
Lex Fridman
Alone with your own thoughts?
Alone with your own thoughts?
Jordan Jonas
With your own thoughts. It was my first time in my life having been like that. And so, it was powerful at the time. What it did too is it gave me a whole different view of life because I had gotten a job when I was 13 and then 14, 15, 16, 17, and then I was just in the normal run of things and then that just threw a whole different path into my life. And then, I realized some of the things while I was traveling that I wouldn’t experience again until I was living with natives and such.

And then, I realized some of the things while I was traveling that I wouldn’t experience again until I was living with natives and such.
And that was you wake up, you don’t have a schedule, you literally just have needs and you just somehow have to meet your needs. And so, there’s a really sense of freedom you get that is hard to replicate elsewhere. And so, that was eye-opening to me. And I think once I did that, I went back. So, I went back to my old job at the salad dressing plant.
And there’s this old cross-eyed guy and he was, “Oh, Hobo Jordo is back.” And that’s where I got it. But at freedom always was very important to me, I think from that time on.
Lex Fridman
What’d you learn about the United States, about the people along the way? Because I took a road trip across the US also and there’s a romantic element there too of the freedom, of the… well, maybe for me not knowing what the hell I’m going to do with my life, but also excited by all the possibilities. And then, you meet a lot of different people and a lot of different kinds of stories.

And also, a lot of people that support you for traveling. Because there’s a lot of people dream of experiencing that freedom, at least the people I’ve met. And they usually don’t go outside of their little town.
They have a thing and they have a family usually, and they don’t explore, they don’t take the leap. And you can do that when you’re young. I guess you could do that at any moment. Just say fuck it and leap into the abyss of being on the road. But anyway, what did you learn about this country, about the people in this country?
Jordan Jonas
You’re in an interesting context when you’re on trains because the trains always end up in the crappiest part of town and you’re always outside interacting. Well, the interesting things, every once in a while you’ll have to hitchhike to get from one place to another. One interesting thing is you notice you always get picked up by the poor people. They’re the people that empathize with you, stop, pick you up, you go to whatever ghetto I remember, you end up in and people are really, “Oh, what are you guys doing?” Real friendly and relatable.

It broadened my horizons for sure, from being just an Idaho kid and then meeting all these different people and just seeing the goodness in people and this and that. It’s also very, a lot of drugs and a lot of people with mental issues that you’re friends with, dealing with and all that kind of stuff.
Lex Fridman
Any memorable characters?
Any memorable characters?
Jordan Jonas
Well, there’s a few for sure. I mean a lot of them I still know that are still around. Rocco was one guy we traveled, he’s become like a brother, but he traveled with my brother for years because they were the two sober guys. He rather than traveling because he was hooked on stuff, did it to escape all that. And so, he was sober and straight edge and he always like 5’7″ Italian guy that was always getting in fights.

He rather than traveling because he was hooked on stuff, did it to escape all that. And so, he was sober and straight edge and he always like 5’7″ Italian guy that was always getting in fights.
And he has his own sense of ethics that I think is really interesting because he is super honest, but he expects it of others. And so, it’s funny in the modern context, the thing that pops in my head is when he got a car for the first time, which wasn’t that long, he was in his 30s or something and he registered it, which he was mad about that he had to register. But then, the next year they told him he had to register again and he is like, “What did you lose my registration?” went down there to the DMV, chewed him out that he had to reregister, because he already registered.
Where’s the paperwork? But he just views the world from a different lens. I thought, but on everything, he’s a character. Now, he just lives by digging up bottles and finding treasures in them.
Lex Fridman
But he notices the injustices in the world and speaks up.
But he notices the injustices in the world and speaks up.

And speaks up and he is always like, “Why doesn’t everybody else speak up about their car registration?” And then, there was, Devo comes to mind because he was such a unique character as far as just for one, he would’ve lived to be a 120 because the amount of chemicals and everything else he put into his body and still, “Hey man,” one of those guys, he could always get a dime. “Oh, spare dime. Spare dime.”

He would bum change. And I’d see him sometimes and I’d be gone and then go to New York to visit my sister or something. And I’d, ” Sure enough, there’s Devo on the street. What do you know?” You go visit him in the hospital because he got bit by 27 hobo spider bites.
It was just always rough, but charismatic, vital, the vitality of life was in him, but it was just so permeated with drugs and alcohol too. It’s interesting.
Lex Fridman
Because I’ve met people like that, they’re just, yeah, joy permeates the whole way of being and they’re like, they’ve been through some. They have scars, they’ve got it rough, but they’ve always got a big smile. There’s a guy I met in the jungle named Pico. He lost a leg and he drives a boat and he just always has a big smile. Even given that the hardship he has to get, everything requires a huge amount of work, but he’s just big smile and there’s stories in those eyes.

Jordan Jonas
It was things, trespassing on a train, but we were riding a train, and my brother woke up, and they had a dead outland on his head, and hit the train and fell on him. And we woke up and we were laughing. That’s got to be some kind of bad omen. And then, we were looking out of the train, and we saw a train worker look, and saw us and he went, like, “Oh, we know that’s a bad omen.”

And then, we were looking out of the train, and we saw a train worker look, and saw us and he went, like, “Oh, we know that’s a bad omen.”
Anyway, sure enough, the police stopped the train. Somebody had seen us on it, and they searched it, got us and threw us in jail. It was not a big deal. We were in jail a couple days, but when we got out, of course they put us… We were in some podunk town in Indiana and we didn’t know where to catch out of there. And so, we were at some factory and we just banning factory.
And we were right there for four days, no train that was going slow enough that we could catch. And then, we found this big old roll of aluminum foil, and now I got to apologize to this woman because we were so bored just sitting there. We built these hats, like horns coming out every which way, and loops, and just sitting there. And it was that night and some minivan pulled up to this train that was going by too. We’re like, “Rr-rr-rr.” We were circling the car.

I didn’t like hitchhiking, just because you’re depending on the other people. I don’t know why, you just want to be independent, but you do meet really cool people. A lot of times there’s really nice people that pick you up and that’s cool. But I just personally actually didn’t do it a lot and I wasn’t… If you’re on the streets for 10 years, you’ll end up doing it a lot more because you need to get from point A to point B, but we just tried to avoid it as much as we could because it didn’t appeal to us as much.

Sometimes you just want to be alone with your thoughts or there is a kind of lack of freedom in having to listen to a person that’s giving you a ride.

It’s so true. And then, you don’t know how to react too. I was young, I remember I got picked up, I was probably 19 or something, and then I was just like, “Hey, how’s it going?” She’s like, “I’m fine. Husband just died.” And then, there’s all, “And I got diagnosed with cancer, and this is and that.” And pretty bitter, and all that, and understandably so, but you’re just like, “I have no idea how to respond here.”

And then, you’re young, and you had to be nice and that. And I remember that ride being interesting because I didn’t really know how to respond, and she was angry, and going through some stuff and dumping it out. She didn’t have anyone else to dump it out on. I was like, “Wow.”

I’ll try to keep it a little bit short on the how. But the long story short was I had a brother that’s adopted, and when he grew up, he wanted to find his biological mom and just tell her thanks. And so, he did. He was probably 20 or something, he found his biological mom, told her things. Turns out he had a brother that was going to go over to Russia and help build this orphanage.

And so, he did. He was probably 20 or something, he found his biological mom, told her things. Turns out he had a brother that was going to go over to Russia and help build this orphanage.
And that brother was about my age. I remember at that time I read this verse that said, “If you’re in the darkness and see no light, just continue following me,” basically. I was like, “Okay, I’m going to take that to the bank even though I don’t know if it’s true or not.” And then, the only glimpse of light I got in all that was when I heard about that orphanage to go build that orphanage.
And I prayed about it and I felt, and I can’t explain, it brought me to tears. I felt so strongly that I should go. And so, I was like, “Well, that’s a clear call. I’m just going to do it.” So, I just bought a ticket, got a visa for a year, and then I went, and helped build an orphanage and we got that built. But he was an American and I wanted to live with the Russians to learn the language.
And so, he sent me to a neighboring village to live with a couple Russian families that needed a hand, somebody to watch their kids, and cut their hay, and milk the cow and all that. So, I found myself in that little Russian village, just getting to know these two guys and their families. It was pretty fascinating. And of course, I didn’t know the language yet and they were two awesome dudes.
Both of them had been in prison, and met each other in prison, and were really close because they found God in prison together, and got out and stayed connected. And so, I’d bounce back between those two families and they used to always tell me about their third buddy they had been in prison with who was a native fur trapper now in the north.
And so, they’d go, “You got to go meet our buddy up north.” And one day that guy came through to sell furs in the city, and he invited me to come live with him, and my visa was about to expire, but I was like, “When I come back, I’ll come.” And so, I went back home, earned some more money and did some construction or whatever. Then, went back and headed north to hang out with Yura and fur trap. And that started a whole new… Opened world that I didn’t know about.
Lex Fridman
Before we talk about Yura and fur trapping, let’s actually rewind. And would you describe that moment when you were in the darkness as a crisis of faith?
Before we talk about Yura and fur trapping, let’s actually rewind. And would you describe that moment when you were in the darkness as a crisis of faith?
Jordan Jonas
Yeah. Yeah, for sure. It was darkness in that I didn’t know how to parse what is this thing that’s my faith, and what’s the wheat, and what’s the chaff and how do I get through it? And I basically just clung to keeping it really simple and oddly enough in my Christian path that God was actually defined in a certain God is love. And I was just like, “That’s the only thing I’m going to cling to.”

And I basically just clung to keeping it really simple and oddly enough in my Christian path that God was actually defined in a certain God is love. And I was just like, “That’s the only thing I’m going to cling to.”
And I’m going to try to express that in my life in whichever way I can and just trust that if I do that, if I act like I… I’ve heard this lately, but if you just act like you believe, over time, that world kind of opens to you. When I said I would go to Russia, I prayed and I was like, “Lord, I don’t see you. I don’t know, but I got this what I felt like was a clear call. I have only one request and that is that you would give me the faith to match my action.”
I’m choosing to believe. I could choose not to because whatever, but I’m going to choose to act and I just ask to have faith someday. And honestly, for the whole first year I went through, that was a very crazy time for me, learning the language, being isolated, being misunderstood, blah-blah, but then trying to approach all that with a loving open heart.
And then, I came back and I realized that that prayer had been answered. That wasn’t the end of my journey, but I was like, “Whoa, that was my deepest request that I could come up with and somehow that had been answered.”
Lex Fridman
So, through that year, you were just like, first of all, you couldn’t speak the language. That’s really tough. That’s really tough.

It’s tough because it’s unlike on a loan where… Because not only can you not speak and you feel isolated, but you’re also misunderstood all the time, so you seem like an idiot and all that. And so, that was tough. I felt very alone at that time, at certain times in that journey.

I was really intentional about trying to… I don’t know why I’m here, I just know that that’s my call is to love one another. And so, I would just try to… And then it meant digging people’s wells. It might meant just going and visiting that old lady babushka up at the house that’s lonely, and that was really cool. I got to talk to some fascinating ladies, and stuff, and then go to that village, help those families.

I’m going to be like cut the hay, be the most hardest worker I can be because that’s my goal here. I didn’t have any other agenda or anything except to try to live a life of love and I couldn’t define it beyond that.
Lex Fridman
What was it like learning the Russian language?
What was it like learning the Russian language?
Jordan Jonas
It was super interesting. I think I had the thought while I was learning it, one that it was way too hard. If I would’ve just learned Spanish or German, I would be so much farther. But here I am a year in and I’m like, “How do you say I want cheese properly?” But at the same time, it was really cool to learn a language that I thought in a lot of ways was richer than English.

It’s a very rich language. I remember there was a comedy act in Russian, but he was saying, “One word you can’t have in English is [foreign language 01:17:32],” meaning I didn’t drink enough to get drunk. That type thing. But it’s just that you can make up these words using different prefixes, and suffixes, and blend them in a way that is quite unique and interesting.
And honestly, would be really good for poetry because it also doesn’t have sentence structure in the same way English does. The words can be jumbled in a way.
Lex Fridman
And somehow in the process of jumbling some humor, some musicality comes out. It’s interesting. You can be witty in Russian much easier than you can in English, witty and funny. And also with poetry, you can say profound things by messing with words in the order of words, which is hilarious because you had a great conversation with Joe Rogan.

And on that program, you talked about how to say I love you in Russian, just hilarious. And it was for me, the first time, I don’t know why you were a great person to articulate the flexibility and the power of the Russian language. That’s really interesting.
Jordan Jonas
Interesting.
Interesting.
Lex Fridman
Because you were saying [foreign language 01:18:40], you could say every single order, every single combination of ordering of those words has the same meaning, but slightly different.

Right, exactly. So, it is rich, and it was interesting coming from an English context, and getting a glimpse of that, and then wondering about all those Russian authors that we all appreciate that, oh, we actually aren’t getting the full deal here.

Lex Fridman
Yeah, definitely. I’ve recently become a fan actually of Larissa Volokhonsky and Richard Pervear. They’re these world-famous translators of Russian literature, Tolstoy, Dostoevsky, Chekov, Pushkin, Bulgakov, Pasternak. They’ve helped me understand just how much of an art form translation really is. Some authors do that art more translatable than others, like Dostoevsky is more translatable, but then you can still spend a week on one sentence.

Just how do I exactly capture this very important sentence? But I think what’s more powerful is not literature, but conversation, which is one of the reasons I’ve been carrying and feeling the responsibility of having conversations with Russian speakers because I can still see the music of it, I can still see the wit of it.

And in conversation comes out really interesting kinds of wisdom. When I listen to world leaders that speak Russian speak, and I see the translation, and it loses the irony. In between the words, if you translate them literally, you lose the reference in there to the history of the peoples.
Jordan Jonas
Yeah, for sure. And I’ve definitely seen that on, and if you listen to, I think it probably was a Putin speech or something, and you just see that, “Oh wow, something major is being lost in translation.” You can actually see it happen. I wouldn’t be surprised if that wasn’t the case with that whole greatest tragedy as the fall of the Soviet Union that I hear him being quoted as saying all the time. I bet you there’s something in there that’s being lost in translation that is interesting.

I’ll just say that that was tangibly the hardest part about learning the language is that humor comes last and you have to wait. You have to wait that whole year or however long it takes you to learn the language to be able to start getting the humor. Some of it comes through, but you miss so much nuance and that was really difficult in interaction with people to just be the guy when there’s humor going on and you’re totally oblivious to it.

Can you talk about their way of life? So, when you’re doing fur trapping-
Jordan Jonas
Fur trapping was an interesting experience. Basically, what you do in October or something, you’ll go out to a hunting cabin and you’ll have three hunting cabins. You’ll go stock them with noodles or whatever it is. And then, for the next couple months or however long, you’ll go from one cabin. Usually, the guys are just out there doing this on their own.

So, they’ll go out, and they’ll go from one cabin, and each cabin will have five or six trap lines going out of it. Every day, it’ll take a half a day to walk to the end of your trap line, open all the traps and a half a day to get back. And they’ll do that. They’ll spend a week at a cabin, open up all the traps, and then it’ll take a day to hike over to the other cabin.
Go to that one, open up all those traps, and then there, and then three weeks later or so, they’ll end up back at the first cabin, and then check all the traps. And so, it’s that rhythm. And they’ll do that for a couple, few months during the winter. And you’re trapping sable, they’re called sable, like Pine Martin is what we would have the equivalent of over here.
Lex Fridman
What is it?
What is it?
Jordan Jonas
It’s like a weasel, a furry little weasel. And they make coats out of it. When I went, he showed me how to open the trap, showed me the ropes, gave me a topographical map. There’s one cabin, there’s the other. And we parted ways for five weeks. We did run into each other once in the middle there at a cabin. But other than that, you’re just off by yourself hoping to shoot a grouse or something to add to your noodles, and make your meal better or catch a fish. And then working really hard, trying not to get lost and stuff.

I got myself into trouble once, and the first time I went to one cabin, I got myself into trouble. First time I went to the other cabin, I nailed it. And so, I had two different experiences on my first trip, but the one that I nailed it, I remember I had to go and it’s like a day hike. I was like, “Well, I know the cabin south, and so if I just walk south, the sun should be on the left in the morning, and right in front of me in the middle of the day, and by evening it should end up at my right.”

And just guess what time it is and follow along. And it takes all day and I kid you not, I ended up a hundred yards from the cabin. I was like, “Whoa, this is the trail and that’s the cabin,” like, “Oh, amazing.” And then, the other time I went out and I was heading over the mountains and I thought hours had passed. I probably had gotten slightly lost, and then I thought I was halfway there.
So, I thought, “Okay, I’m going to sit down and cook some food, get a drink. I’m thirsty.” So, I sat down, and went to start a fire, and my matches had gotten all wet because the snow had fallen on me, and soaked me, and I didn’t have them wrapped in plastic. I was like, “Oh no, I can’t drink water.” So, I was like, “Well, I’m just going to power through.”
I’m halfway there where I kept hiking and then I realized it was getting night. And then, I even realized I was at the halfway point because I saw this rock. I was like, “Oh no, that’s the halfway point.” I was like, “I can’t do this.” And so, I need to go get water. I ended up having to divert down the mountain and head to the water. There was a whole ordeal.
I had to take my skis off because I was going through an old forest fire burn, so they were all really close trees, but then the snow was like this deep. So, I was just trudging through and just wishing a bear would eat me, get it over with. But I finally made it down to the water, chopped a hole through the ice, I was able to take a sip.

And I laid down, I was about to go to sleep, and then Yura charges in from there. I was like, “Whoa, dude, what are you doing?” And I was like, “How’s it going?”

And we went to sleep, and the next morning we parted ways and who knows what.

Right. It’s like just put one foot in front of the other. When you think about what you have to do, it’s really intimidating, but you just know if I just do it, if I just do it, if I just keep trudging, eventually I’ll get there. And pretty soon you realize, “Oh, I’ve covered a couple kilometers.” And so, when you’re really in it in those moments, I guess you’re just putting your head down and getting through.

One of the things I’ve realized that was helpful in the jungle, that was one of the biggest realizations for me is it really sucks right now.

It’s so funny how just awareness of that, having been through it and then being aware of it means next time you face it, you’ll be like, “You know what, once this is over, I’m going to look back on it and it’s going to be like that and nothing.” And I’ll actually laugh about it and think it was… It’s the thing I’ll remember.

I remember that story of that miserable day going down to the ice and I can smile about it now. And now that I know that, I can be in a miserable position and realize that that’s what the outcome will be once it’s over. It’s just going to be a story.

It was the first time. So, to continue the story slightly, I went fur trapping with that guy. And then, it turned out all his cousins were these native nomadic reindeer herders. And after I earned his trust, and he liked me a lot, he took me out to his cousins who were all these nomads living in teepees. I was like, “This is awesome. I didn’t even know people still lived like this.”

And after I earned his trust, and he liked me a lot, he took me out to his cousins who were all these nomads living in teepees. I was like, “This is awesome. I didn’t even know people still lived like this.”
And they were really open and welcoming because their cousin just brought me out there and vouched for me. But it was during fencing season and fencing in Siberia for those reindeer is an incredible thing. You take an axe, you go out and you just build these 30-kilometer loop fences with just logs interlocking. It’s tons of work. And all these guys are more efficient bodies, they’re better at it.
And I’m just working less efficiently and also a lot bigger dude, but we’re all just on the same rations kind of. And I got down that. I was like 155 pounds getting down pretty dang skinny for my 6’3″ frame and just working really hard. And in the spring in Siberia, there’s not much to forage. In the fall, you can have pine nuts and this and that, but in the spring, you’re just stuck with whatever random food you’ve got.
And so, that’s where I lost the most weight, and felt the most hungry, and I had a lot of other issues. I was new to that type of work. And so, working as hard as I could, but also making mistakes, chopping myself with the axe and getting injured, all kinds of stuff.
Lex Fridman
So, injuries plus very low calorie intake.

I remember if you got… You were this poor son of a gun to get stuck slicing the bread, you’re here cutting the bread and somebody throws all the spoons and drops the pot of soup there. And it’s like before you can even done slicing, you slice all the meats like gone from the bowl. Everybody else has grabbed the spoon in midair and you’re just like, “Ah.” Hoping this one little noodle is going to give me a lot of nourishment.

Jordan Jonas
So, the natives, when I got there, I grew up on a farm. I thought I was pretty good with an axe, but they do tons of work with those things and I really grew to love their type of axe, their style of axe, and just an axe in general. They’d always say it’s the one tool you need to survive in the wilderness and I agree. Because this one has certain design features that the natives… That was unique to the Evenki, key to the natives I was with.

One is with these Russian heads or the Soviet heads, whatever they had, they’re a little wider on top here. Meaning, you can put the handle through from the top like a tomahawk, and that means you’re not dealing with a wedge. And if it ever loosens and you’re swinging, it only gets tighter. It doesn’t fly off. And so, that’s something that’s cool. What they do that’s unique is, so you can see, this is the wolverine axe. So, it’s got the little wolverine head in honor of the wolverine I fought on the show.
Lex Fridman
So, you have actually two axes. This is one of the smaller.
So, you have actually two axes. This is one of the smaller.
Jordan Jonas
This is a little smaller. I didn’t want to make it too small because you need something to actually work out there. You need something kind of serious. But then they sharpen it from one side. So, if you’re right-handed, you sharpen it from the right side. And that means when you’re in the woods and living, there’s a lot of times whether you’re making a table, or a sleigh, or an axe handle or whatever you’re doing, that you’re holding the wood and doing this work.

And it makes it really good for that planing. The other thing it is, especially in northern woods, all the trees are like this big. You’re never cutting down a big giant tree. And so, when you swing with a single sided axe like this, sharpen from the one side, with your right-hand swing like this, it really bites into the wood and gives you a… Because with that, if you can picture it, that angle is going to cause deflection.
And without that angle on your right hand and swing, it just bites in there like crazy. And so, that, there’s other little… The handle is made by some Amish guys in Canada. This is all hand forged by-

There’s other thing, I slightly rounded this pole here. It’s just a little nuance because when you pound a stake in, if you picture it, if it’s convex, when you’re pounding it, it’s going to blow the fibers apart. If it has just a slight concave, it helps hold the fibers together. And so, it’s a little nuance, not too flat because you want to still be able to use the back as you would.

What kind of stuff are you using the axe for?
What kind of stuff are you using the axe for?

So, the axe is super important to chop through ice in a winter situation, which you probably hopefully won’t need. But what I use an axe all the time for is when it’s wet, and rainy, and you need to start a fire. It’s hard to get to the middle of dry wood if just a knife or a saw. And so, I can go out there, find a dead tall tree, a dead standing tree, chop it down, split it apart, split it open, get to the dry wood on the inside, shave it some little curls and have a fire going pretty fast.

And so, if I have an axe, I feel always confident that I can get a quick fire in whatever weather and I wouldn’t feel the same without it in that regard. So, that’s the main thing. Of course, you can use it. I use it if you’re taking an animal apart or if you’re… All kinds of, what else? Building a shelter, skinning teepee poles or whatever you’re doing.
Lex Fridman
What’s the use of a saw versus an axe?
What’s the use of a saw versus an axe?
Jordan Jonas
I greatly prefer an axe. A saw though has… Its value goes up quite a bit when you’re in hardwoods. When you’re in a hardwood oaks, and hickory and things like that, they’re a lot harder to chop. So, a saw is pretty nice in those situations, I’d say. In those situations, I’d like to have both in the north woods and in more coniferous forests.

I don’t think there’s enough advantages that a saw incurs. With a good axe, you’ll see people with little camp axes, and stuff, and they just don’t think they like axes. It’s like, “Well, you haven’t actually tried to…” Try a good one first and get good with it. The one thing about an axe, they’re dangerous. So, you need to practice, always control it with two hands, make sure you know where it’s going to go.
It doesn’t hit you, or when you’re chopping, like say you’re creating something that you’re not doing it on rocks and stuff so that you’re doing it on top of wood so that when you’re hitting the ground, you’re not dulling your axe. You got to be a little bit thoughtful about it.
Lex Fridman
Have you ever injured yourself with an axe in the early days?
Have you ever injured yourself with an axe in the early days?
Jordan Jonas
Yeah. So, I had gotten a knee surgery and then about three months later, had torn my ACL. I went over to Russia and I was like, “Well, I got a good knee. It’s okay.” And then, that’s when I was building that fence that first time. And at one point, I chopped my rubber boot with my axe because it reflected off and I was new to them. And I was really frustrated because I’d done it before.

And I was really frustrated because I’d done it before.
And the native guy was like, “Oh, I think there’s a boot we left.” A few years ago, we left a boot four kilometers that way. So, we got the reindeer, took him, rode him over. Sure enough, there’s a stump with a boot upside down, pull it off, put it on. I was like, “Sweet. I’m back in business.” I went back a couple of days later, pting, chum, chopped it, cut your foot, cut my rubber boot.
And I was just like, “Dang it.” And I was mad enough that I just grabbed the axe, and swung it at the tree, and it just one-handed, and deflected off and bam, right into my knee.
Lex Fridman
Oh no.
Oh no.
Jordan Jonas
And I was like, “Oh.” I fell down. I was like, “Oh my gosh,” because you get your axe really razor sharp, and then just swung it into my knee. I didn’t even want to look. I was like, “Oh no.” I looked and it wasn’t a huge wound because it had hit right on the bone of my knee, but it split the bone, cut a tendon there, and I was out in the middle of the woods.

So, literally, I knew I was in shock because I’m just going to go back to teepee right now. So, I ran back to teepee, laid down, and honestly, I was stuck there for a few days. I was in so much pain and my other knee was bad. It was rough. I literally couldn’t even walk at all or move. There was a plastic bag, I had to poop in it and roll to the edge of the teepee, shove it under the moss. I just totally immobilized.

There you go. It’s such a lesson too. There were so many of those and I was always in a little bit over my head, but like I said, you do that enough and you make a lot of mistakes, but every time you learn. Now, it’s like an extension of my arm. That’s not going to happen because I just know how it works now.

It depends on your environment, but I will say in most of the forests that I spend a lot of time in, all the north woods, the best thing you can do is find a dead standing tree. So, it can be down pouring rain, and you chop that tree down and then when you split it open, no matter how much it’s been raining, it’ll be dry on the inside. So, chop that tree down, chop a piece, a foot long piece out, and then split that thing open and then split it again.

So, chop that tree down, chop a piece, a foot long piece out, and then split that thing open and then split it again.
And then, you get to that inner dry wood, and then you try to do this maybe under a spruce tree or under your own body so that it’s not getting rained on while you’re doing it. Make a bunch of little curls that’ll catch a flame or light, and then you make a lot more kindling and little pieces of dry wood than you think, because what’ll happen, you’ll light it and it’ll burn through and like, “Dang it.”
So, just be patient, you’re going to be fine. Make a nice pile of curls that you can light or spark and then get a lot of good dry kindling. And then, don’t be afraid to just boom, boom, boom, pile a bunch of wood on and make a big old fire. Get warm as fast as you can. It’s amazing how much that of a recharge it is when you’re cold and wet.
Lex Fridman
You can throw relatively wet wood on top of that.

So, on a lot of pine trees, a place where the tree was injured when it was alive, it pumps sap to it. And this is a good point because I use this a lot. It pumps that tree full of sap and then years later the tree dies, dries out, rots away. But that sap infused wood, it’s like turpentine in there. It’s oily. And so, if it gets wet, you can still light it. It repulses water.

And so, if you can find that in a rainstorm, you can just make a little pile of those shavings, get the crappiest spark or quickest light, and it’ll sit there and burn like a factory fire starter. It’s really, really nice. That’s good to spot. It’s a good thing to keep your eye out for.

Yeah, it’s really fascinating. And then, you make this thing.

So, there’s this big river called the Yenisei that feeds through the middle of Russia and there’s a bunch of tributaries off of it. And one of the tributaries is called the Podkammennaya Tunguska. And I was up that river and just a little ways north is another river called the Bakhta, and that’s where that village is where they filmed Happy People. So, in Siberian terms, we’re neighbors.

There’s something really, really powerful about spending that much time, being independent, depending on what we talked about a little earlier. But you’re putting yourself in these situations all the time where you’re uncomfortable, where it’s hard, but then you’re rising to the occasion, you’re making it happen. There’s nobody. When you’re fur-trapping by yourself, there’s nobody else to look at to blame for anything that goes wrong. It’s just yourself that you’re reliant on.

When you’re fur-trapping by yourself, there’s nobody else to look at to blame for anything that goes wrong. It’s just yourself that you’re reliant on.
And there’s something about the natural rhythms that you are in when you’re that connected to the natural world that really does feel like that’s what we’re designed for. And so, there’s a psychological benefit you gain from spending that much time in that realm. And for that reason, I think that people that are connected to those ways are able to tap into a particular…
I noticed it a lot with the natives. So, if I met the natives in the village, I would think of them as unhappy people. They drink a lot and always fighting. The murder rate is through the roof. The suicide rate’s through the roof. But if you meet those same people out in the woods living that way of life, I thought, these are happy people. And it’s an interesting juxtaposition to be the same person.
But then, I lived in a native village that had the reindeer herding going on around it, and everybody benefited because of that. I also went to a native village that they didn’t hold those ways anymore. And so, everybody was just in the village life. And it just felt like a dark place. Whereas, the other native village, it was rough in the village because everybody drank all the time. But it had that escape… it had that escape valve. And then, once you’re out there, it’s just a whole different world. And it was such an odd juxtaposition.
Lex Fridman
It’s funny that the people that go trapping experience that happiness and still don’t have a self-awareness to stop themselves from then drinking and doing all the dark stuff when they go to the village. It’s strange that you’re not able to… you’re in it, you’re happy, but you’re not able to reflect on the nature of that happiness.

It’s really weird. I’ve thought about that a lot, and I don’t know the answer. It’s like there’s a huge draw to comfort. There’s a huge… and it’s all multifaceted and somewhat complex, because you can be out in the woods and have this really cool life.

I will say it’s a little bit different for men than women, because the men are living the dream as far as what I would like. So, you’re hunting and fishing and managing reindeer and you got all these adventures. So, what ends up happening is that a lot more guys than young men out there in the woods. And so, there’s a draw, also, I think, to go to the village probably to find a woman. And then there’s a draw of technology and the new things. But then once they’re there, honestly, alcohol becomes so overwhelming that everything else just fiddles away.

And then he’d sober up. And then he was like a month blackout drunk, and now he’s sobered up. And now, boom, back into life, back into being a knowledgeable, capable person. And because comfort’s so available to us all, you almost have to force yourself into that situation, plan it out, “Okay, I’m going to go do that.”

So, one of the things that really impacted me when I was a young man, and I read The Gulag Archipelago, was don’t pursue happiness because the ingredients to happiness can be taken from you outside of your control, your health, but pursue spiritual fullness, pursue, I think he words it duty, and then happiness may come alongside. Or it may not. So, he gives the example that I thought was really interesting. In the prison camps, everybody’s trying to survive and they’ve made that their ultimate goal, “I will get through this.” And they’ve all basically turned into animals in pursuit of that goal and lying and cheating and stealing. And then he was like, somehow the corrupt Orthodox Church produced these little babushkas who were candles in the middle of all this darkness because they did not allow their soul to get corrupted. And he is like, “What they did do is they died. They all died, but they were lights while they were alive, and lost their lives, but they didn’t lose their souls.” So, for myself, that was really powerful to read and realize that the pursuit of happiness wasn’t exactly what I wanted to aim at. I wanted to aim at living out my life according to love, like we talked about earlier.

So, for me personally, my personal experience of that is I thought when I went to Russia that I gave up… in my 20s, I spent my whole 20s living in teepees and doing all this stuff that I thought, “I should give be getting a job, I should be pursuing a career, I should get an education of some sort. What am I doing for my future?”

What am I doing for my future?”
But I felt I knew where my purpose was, I knew what my calling was. I’m just going to do it. And it sounds glamorous now when I talk about it, but it sucked a lot of the times. And it was a lot of loneliness, a lot of giving up what I wanted, a lot of watching people I cared about. You put all this effort in, and then you just see the people that you put all this effort and just die and this and that, because that happened all the time.
And then the other thing I thought I gave up was a relationship because you couldn’t… I wasn’t going to find a partner over there. And so, interestingly enough now in life, I can look back and be like, “Whoa, weird. Those two things I thought I gave up is where I’ve been almost provided for the most in life.” Now, I have this career guiding people in the wilderness that I love. I genuinely love it. I find purpose in it. I know it’s healthy and good for people. And then I have an amazing wife and an amazing family. How did that happen? But I didn’t exactly aim at it. I consciously, in a way, I mean I hoped it was tangential, but I aimed at something else, which was those lessons I got from the Gulag Archipelago.
Suffering
Lex Fridman
Just because you mentioned Gulag Archipelago, I got to go there. You have some suffering in your family history, whether it’s the Armenian, Assyrian genocide or the Nazi occupation of France. Maybe, you could tell the story of that, the survival thing, it runs in your blood, it seems.

I love history. I find so much richness in knowing what other people went through and find so much perspective in my own place in the world. I have the advantage of in my direct family, my grandparents, they went through the Armenian genocide. They were Assyrians. It was a Christian minority, indigenous people in the Middle East. They lived in Northwestern Iran.

I have the advantage of in my direct family, my grandparents, they went through the Armenian genocide. They were Assyrians. It was a Christian minority, indigenous people in the Middle East. They lived in Northwestern Iran.
And during the chaos of World War I, the Ottoman umpire was collapsing and it had all kinds of issues. And one of its issues was it had a big minority group and it thought it would be a good time to get rid of it. And they can justify it in all the ways you can, like, there’s some people that were rebelling or this or that, but ultimately, it was just a big collective guilt and extermination policy against the Armenians and the Assyrians.
And my grandparents, my grandma was 13 at the time, and my grandpa was 17, which is interesting. It happened almost 100 years ago, but my dad was born when my grandma was pretty old. But my grandmother, her dad was taken out to be shot. The Turks were coming in and rounding up all the men, and they took them out to be shot. And then they took my grandma and her. She had seven brothers and sisters and her mom. And they drove her out into the desert, basically.
Her dad got taken out to be shot. So, his name was Shaman Yumara, whatever, took him out. They were all tied up, all shot, needs to say a quick prayer before they shot him. But he fell down and he found he wasn’t hit. And usually, of course, they’d come up and stab everybody or finish them off, but there was some kind of an alarm, and all the soldiers rushed off and he found himself in the bodies and was able to untie himself. They were naked and hungry and all that.
And he ran out there, escaped, went into a building and found the loaf of bread wrapped in a shirt and was able to escape, fled. He never saw his family for… so, to continue the story, my grandma got taken with her mother and brothers and sisters. They just drove them into the desert until they died, basically, and run them around in circles and this and that, and then all the raping and pillaging that accompanies it.
And at one point, her mom had the baby and the baby died. And her mom just collapsed and said, “I just can’t go any further.” And my grandma and her sister picked her up to, “We got to keep going,” and picked her up. They left the baby along with the other. Everybody else had died. It was just the three of them left.
And somehow, they bumbled across this British military camp and were rescued. Neither of the sister nor my great-grandmother ever really recovered, from what I understand, but my grandma did. At the same time, in another village in Iran there, the Turks came in and were burning down my grandpa’s village and they caught. And my grandpa’s dad was in a wheelchair and he had some money belt and he stuffed all his money in it and gave it to grandpa and just told him to run and don’t turn back. And they came in the front door as he was running out the back, and he never saw his dad again. But he turned around and saw the house on fire, never knew what happened to his sister. And so, he was just alone. He ran.
At some point, I can’t remember, he lost his money belt and he took his jacket off, forgot it was something happened. Anyway, so he was in a refugee camp. He ended up getting taken in by some Jesuit missionary. So, anyway, both of them had lost basically everything. And then, at some point, they met in Baghdad, started a family, immigrated to France. And then it just so happened to be right before World War II.
And so, the Nazis invaded. My aunt, she’s still alive, but she actually met a resistance fighter for the French under a bridge somewhere. And they fell in love, and she got married. So, she had an inn on the French resistance at one point. And of course, they were all hungry. They’d recently immigrated, but also had this Nazi occupation and all that. And so, Uncle Joe, the resistance fighter guy, told him, like, “Hey, we’re going to storm this noodle factory, come.” And so, they stormed the noodle factory and all my aunts surrounding there and we’re throwing out noodles into wheelbarrows and everybody was running.
And then the Nazis came back and took it back over and shot a bunch of people and everything. And grandpa, he had already come from where he came from, was paranoid. So, he buried all the noodles out in the garden. And then my two aunts got stuck in that factory overnight with all the Nazi guards or whatever. And then the Nazi guards went all from house to house to find everybody that had had noodles and punish them. But they didn’t find my grandpa’s, fortunately. They searched his house, but not the garden.
So, they had noodles. And somehow, it must’ve been in the same factory or something, but olive oil, and they just lived off of that for all the whole war years. My aunts ended up getting out of the… they hid behind boxes and crates overnight and stuff, and the resistance stormed again in the morning and they got away and stuff. But anyway, chaos. So, when they moved to America, I will say, the most patriotic family everywhere ever, they loved it. It was paradise here.

Look, I’m just one generation away from all that suffering. My aunts and uncles and dad and stuff were the kids of these people. And somehow, I don’t have that. What happened to all that trauma? Somehow, my grandparents bore it, and then they were able to build a family, but not just a family but a happy family. I knew all my aunts and uncles and I didn’t know them. They died before me. But it was so much joy. The family reunions were the best thing ever at the Jonases. And it’s just like, how in one generation did you go from that to that? And it must have been a great sacrifice of some sort to not pass that much resentment. What did they do to break that chain in one generation?

Do you think it works the other way, like, where their ability to escape genocide, to escape Nazi occupation gave them a gratitude for life?

It’s not a trauma in the sense like you’re forever bearing it. The flip side of that is just gratitude to be alive when you know so many people did not survive.

Jordan Jonas
Yeah, it must be, because the only footage I saw of my grandma was they were all the kids and stuff. And they were cooking up a rabbit that they were raising or whatever. But a joyful woman, you could see it in her. And she must’ve understood how fortunate she was and been so grateful for it and so thankful for every one of those 11 kids she had.

But a joyful woman, you could see it in her. And she must’ve understood how fortunate she was and been so grateful for it and so thankful for every one of those 11 kids she had.
So, I recognized it again in my dad. My dad went through a really slow painful decline in his health. And he had diabetes, ended up losing one leg. And so, he lost his job. He had to watch my mom go to school. All he wanted to do was be a provider and be a family man. I bet the best time in his life was when his kids ran to him and gave him a hug. But then, all of a sudden, he found himself in a position where he couldn’t work and he had to watch his wife go to school, which was really hard for her, and become the breadwinner for the family. And he just felt a failure. And I watched him go through that.
After all these years of letting that foot heal, we went out first day and we were splitting firewood with the splitter. And he was just, ” So good to be back out, Jordan. It’s so nice.” And he crushed his foot in the log splitter and you’re just like, “No.” And so, then they just amputated it. We’ve got both legs amputated, and then his health continued to decline. He lost his movement in his hands. So, he was incapacitated, to a degree, and in a lot of pain. I would hear him at night in pain all the time.
And I delayed a trip back to Russia and just stayed with my dad for those last six months. And it was so interesting, having had lost everything. I’ve watched him wrestle with it through the years, but then he found his joy and his purpose just in being almost, I mean, a vegetable. I’d have to help him pee, roll him onto the cot, take him to dialysis. But we would laugh. I’d hear him at night crying or in pain, like, “Ah.” And then in the morning he’d have encouraging words to say.
And I was like, “Wow, that’s how you face loss and suffering.” And he must’ve gotten that somehow from his parents. And then I find myself on this show, and I had a thought, “Why is this easy to me,” in a way? “Why is this thing that’s…” and it just felt like this gift that had handed down and now would be my duty to hand down. But it’s an interesting…
Lex Fridman

So, that’s on the survivor side. What about on the people committing the atrocities? What do you make of the Ottomans, what they did to Armenians or the Nazis, what they did to the Jews, the Slaws, and basically everyone? Why do you think people do evil in this world?

It’s interesting that it is really easy, right? It’s really easy. You can almost sense it in yourself to justify a little bit of evil, or you see yourself cheer a little bit when the enemy gets knocked back in some way. In a way, it’s just perfectly naturalist for us to feed that hate and feed that tribalism in group outgroup, “We’re on this team.” And I think that can happen… I think it just happens slowly, one justification at a time, one step at a time. You hear something and it makes you think then that you are in the right to perform some kind of… you’re justified and break a couple eggs to make an omelet type thing. But all of a sudden, that takes you down this whole train to where, pretty soon, you’re justifying what’s completely unjustifiable.

I think that’s why, for me, having a path of faith works as a mooring because it can help me shine that light on myself. It’s like something outside. If you’re just looking at yourself and looking within yourself for your compass in life, it’s really easy to get that thing out of whack. But you need a perspective from what you can step out of yourself and look into yourself and judge yourself accordingly. Am I walking in line with that ideal? And I think without that check, you’re subject. It’s easy to ignore the fact that you might be able to commit those things. But we live in a pretty easy, comfortable society. What if you pictured yourself in the position of my grandparents and then, all of a sudden, you got the upper hand in some kind of a fight? What are you going to do? You’d definitely picture becoming evil in that situation.

I think one thing faith in God can do is humble you before these kinds of complexities of the world. And humility is a way to avoid the slippery slope towards evil, I think. Humility that you don’t know who the good guys and the bad guys are, and you defer that to bigger powers to try to understand that.

It really is. It’s so inherent and so natural in us to justify ourselves. Just understanding history, read history, it blows my mind that, and I’m super thankful that, somehow, and this has been misused so much, but somehow this ideology arose that love your enemies, forgive those that persecute you, and just on down the line that something like that rose in the world into a position where we all accept those ideals, I think, is really remarkable and worth appreciating.

That said, a lot of that gets wrapped up in what is so natural. It just becomes another instrument for tribalism or another justification for wrong. And so, I even myself, am self-conscious sometimes talking about matters of faith, because I know when I’m talking about something else than what someone else might think of when they hear me talking about it. So, it’s interesting.
God
Lex Fridman
Yeah, I’ve been listening to Jordan Peterson talk about this. He has a way of articulating things, which are sometimes hard to understand in the moment, but when I read it carefully afterwards, it starts to make more sense. I’ve heard him talk about religion and God as a base layer, like a metaphorical substrate from which morality of our sense of what is right and wrong comes from, and just our conceptions of what is beautiful in life, all these kinds of higher things that are fuzzy to understand, that their religion helps create this substrate for which we, as a species, as a civilization, can come up with these notions. And without it, you are lost at sea. I guess for him, morality requires that substrate.

Jordan Jonas
Like you said, it’s kind of fuzzy. So, I’ve only been able to get clear vision of it when I live it. It’s not something you profess or anything like that. It’s something that you take seriously and apply in your life. And when you live it, then there’s some clarity there, but that it has to be defined. And that’s where you come in with the religion and the stories, because if you leave it completely undefined, I don’t really know where you go from there. Actually isn’t a funny to speak to that. I did mushroom. Have you ever done those before?

I’ve done them a couple of times, but one time was, didn’t do that many the other time more. And I had a really experience in helping couch all this in a proper context for myself. So, when I did it, I remember I was sitting on a swing and I could see everything was so blissful, except I could see my black hands on these chains on the swing, but everything else was blissful and amorphous, and I could see the outline of my kids and I could just feel the love for them. And I was just like, “Man, I just feel the love. It’s so wonderful.”

And I was just like, “Man, I just feel the love. It’s so wonderful.”
But then, at times, I would try to picture them, and I couldn’t quite picture the kids, but I could feel the love. And then I started asking all the deepest existential questions I could, and it felt like I was just one answer, another answer, another answer. Everything was being answered. And I felt like I was communing with God, whatever you want to say.
But I was very aware of the fact that that communing was just peeling back the tiniest corner of the infinite, and it just dumped me with every answer I felt I could have. And it blew me away. So, then I asked it, “Well, if You’re the infinite, why did You reveal to me yourself? Why did You use the story of Jesus to reveal yourself?” And then that infinite amorphous thing had to, somehow, take form for us to be able to relate to it. It had to have some kind of a form. But whenever you create a form out of something, you’re boxing it in and subjugating it to boundaries and stuff like that. And then that subject to pain and subject to the brokenness and all that.
And I was like, “Oh, wow.” But when I had that thought, then, all of a sudden, I could relate my dark hands on the chains to the rest of the experience, and then all of a sudden I could picture my children as the children rather than this amorphous feeling of love. It was like, “Oh, there’s Alana and Alta and Zion.” But then they were bounded, and then once they’re bounded, you’re subject to the death and to the misunderstanding and to all that. I picture the amoeba or the cell, and then when it dies, it turns into a unformed thing.
So, we need some kind of form to relate to. So, instead of always just talking about God completely and tangibly, it gave me a way to relate to it. And I was like, “Wow, that was really powerful to me,” and putting it in a context that was applicable.
Lex Fridman
But ultimately, God is the thing that’s formless, that is unbounded, but we humans need.

Right. And then that was always, a lot of my family and loved ones and friends have completely left the faith. And I totally, in a way, I get it. I understand, but I also really see the baby that’s being thrown out with the bathwater. And I want to cherish that, in a way, I guess.

And it’s interesting that you say that the way to know what’s right and wrong is you have to live it. Sometimes, it’s probably very difficult to articulate. But in the living of it, do you realize it?
And it’s interesting that you say that the way to know what’s right and wrong is you have to live it. Sometimes, it’s probably very difficult to articulate. But in the living of it, do you realize it?
Jordan Jonas
Yeah. And I’m glad you say that because I’ve found a lot of comfort in that, because I feel somewhat inarticulate a lot of the times and unable to articulate my thoughts, especially on these matters. And then you just think it’s, “I just have to.” I can live it. I can try to live it. And then what I also am struck with right away is I can’t, because you can’t love everybody, you can’t love your enemies, and you can’t…

And then what I also am struck with right away is I can’t, because you can’t love everybody, you can’t love your enemies, and you can’t…
But placing that in front of you as the ideal is so important to put a check on your human instincts, on your tribalism, on your… I mean, very quickly, like we were talking about with evil, it can really quickly take its place in your life, you almost won’t observe it happening. And so, I much appreciate all the me striving. I grew up in a Christian family, so I had these cliches that I didn’t really understand, like a relationship with God, what does that mean?
But then I realized, when I struggled with trying, with taking… I actually did try to take it seriously and struggle with what does it mean to live out of life of love in the world? But that’s a wrestling match. It’s not that simple. It sounds good, but it’s really hard to do. And then you realize you can’t do it perfectly. But in that struggle, in that wrestling match is where I actually sense that relationship. And then that’s where it gains life and how that… and I’m sure that relates to what Jordan Peterson is getting at in his metaphor.
Lex Fridman

One thing I noticed really tangibly on alone was that, because I had so many people that were close to me, just leave it all together, I was like, “I could do that. I actually understand why they do, or I could not. I do have a choice.” And so, I had to choose at that point to maintain that ideal because I could add enough time on alone. One nice thing is you don’t have any distractions. You have all the time in the world to go into your head. And I could play those paths out in my life. And not only in my life, but I feel like societally and generationally. I throw it all away and everybody start from square one, or we can try to redeem what’s valuable in this and wrestle with it. And so, I chose that path.

Well, I do think it’s like a wrestling match. You mentioned Gulag Archipelago. I’m very much a believer that we all have the capacity for good and evil. And striving for the ideal to be a good human being is not a trivial one. You have to find the right tools for yourself to be able to be the candle, as you mentioned before.

And then for that, religion and faith can help. I’m sure there’s other ways, but I think it’s grounded in understanding that each human is able to be a really bad person and a really good person. And that’s a choice. It’s a deliberate choice. And it’s a choice that’s taken every moment and builds up over time.

And the hard part about it’s you don’t know. You don’t always have the clarity using reason to understand what is good and what is right and what is wrong. You have to live it with humility and constantly struggle. Because then, yeah, you might wake up on a society where you’re committing genocides and you think you’re the good guys. And I think you have to have the courage to realize you’re not. It’s not always obvious.

Right. You got to wrestle with it. It’s like, that quote, the line between good and evil goes through the heart of every man, and we push it this way and that. And our job is to work on that within ourselves.

Yeah, that’s the part. That’s what I like. The full quote talks about the fact that it moves. The line moves moment by moment, day by day. We have the freedom to move that line. So, it is a very deliberate thing. It’s not like you’re born this way and it’s it.

And especially in conditions that are worn peace, in the case of the camps, absurd levels of injustice, in the face of all that, when everything is taken away from you, you still have the choice to be the candle like the grandmas. By the way, grandmas, in all parts of the world, are the strongest humans.

Yeah, he does an incredible job with it. Have you seen the full version? Have you watched the four-part full version? You should. You’d like it. It’s in Russian, and so you’ll get the fullness of that. And he had to fit it into a two-hour format. So, I think what you lose in those extra couple hours is worth watching. I think you’ll like it.

Yeah, I think that’s important to recognize because it’s really easy, I mean especially with what I do and what I talk about, and I see so much of the value in nature. Gosh, I also see a beautiful moose and a calf running around, and then next week I see the calf ripped the shreds by wolves and you’re just like, “Oh.” And it’s not as Rousseauian as we like to think. Things must die for things to live, like you said. And that’s just played out all the time. And it’s indifferent to you, doesn’t care if you live or die, and doesn’t care how you die or how much pain you go through while you… It’s pretty brutal. So it’s interesting that he taps into that, and I think it’s valuable because it’s easy to idealize in a way.

Yeah, the indifference is… I don’t know what to make of it. There is an indifference. It’s a bit scary, it’s a bit lonely. You’re just a cog in the machine of nature that doesn’t really care about you.

Totally. I think that’s something I sat with a lot on that show, is another part of the depths of your psychology to delve into. And that’s when I thought I understand that deeply, but I could also choose to believe that for some reason it matters, and then I could live like it matters, and then I could see the trajectories. And that was another fork in the road of my path, I guess.

In the context of that indifference, isn’t it interesting that we assign so much value, and love, and appreciation for these animals? And in some degree we get that back in a… I think right now you just said the reindeer. I think of the one they gave me because he was long and tall, so they named him [inaudible 02:18:16], and I just remember [inaudible 02:18:19], and just watching him eat the leaves, and go with me through the woods, and trust him to take me through rivers and stuff. And it really is special. It’s really enriching to have that relationship with an animal. And I think it also puts you in a proper context.

One thing I noticed about the natives who live with those animals all the time is they relate to life and death a little more naturally. We feel really removed from it, particularly in urban settings. And I think when you interact with animals, and you have to confront the life and the death of them and the responsibility of a symbiotic relationship you have, I think it opens it a little bit awareness to your place in the puzzle, and puts you in it rather than above it.

I wonder. You wonder when it actually comes, what you’re going to think. But I did have my dad to watch, confronted in as positive a manner as you could. And that’s a big advantage. And so I think when the time comes that I will be ready, but I think that’s easy to say when the time feels far off. It’ll be interesting if you got a cancer diagnosis tomorrow and stage four. It’ll be heavy.

Did you ever confront death while in survival situations when you’re in?
Jordan Jonas
I had a time where I thought I was going to die. I had a lot of situations that could have gone either way, and a lot of injuries, broken ribs and this and that. But the one that I was able to be conscious through a slowly evolving experience that I thought I might die in was at one point, we were siphoning gas out of a barrel, and it was almost to the bottom, and I was sucking really hard to get the gas out. And then I didn’t get the siphon going, so I waited. And then while I was sitting there, [inaudible 02:20:21] put a new canister on top and put the hose in, and I didn’t see. And so then I went to get another siphon and I went, sucked as hard as I could, and just instantly a bunch of gas filled my mouth, and I couldn’t spit it out. I had to go like that, and I just mouthful of gas that I just drank and I was just like, “What is that going to do?”

I had to go like that, and I just mouthful of gas that I just drank and I was just like, “What is that going to do?”
And he and my friend, were going to go on this fishing trip, and so was I. And I was just like, “I might just stay.” And I was in this little Russian village and they’re like, “All right, well.” [inaudible 02:20:57] was like, “Man, I had a buddy that died doing that with diesel a couple of years ago. Man.”
So anyway, I made my way to the hospital, and by then you’re really out of it. And they put me in this little dark room. It almost sounds unrealistic, but it’s exactly how it happened. They put me in a little room with a toilet, and they gave me a galvanized bucket, and then they just had a cold water faucet and they’re just like, “Just chug water, puke into the toilet, and just flush your system as much you can.” But they only had a cold water faucet. So I was just sitting there like chug, chug, chug, until you puke, and chug until you puke, and I’m in the dark. And I started to shiver, because I was so cold, but I just had to still get this thing up to me and chug until I puked. I was picturing, I remember reading about the Japanese torture where they would put a hose in somebody and then make them drink water until they puke.
Anyway, and I just felt so… The only way I can express it, I felt so possessed, demon possessed. I was just permeated with gas. I could feel it was coming out of my pores, and I wanted to rip it out of me and I couldn’t. I’d puke into the toilet and then couldn’t see, but I was wondering if it was rain.
And then I just remember, I could tell I was going out pretty soon, and I remember looking at my hands up close. I’d see them a little bit and I was like, “Oh, that’s how dad’s hands looked.” They were alive, alive, and then interesting. Are my hands going to look like that and a few minutes or whatever.
So then I wrote down to my family what I thought, “I love you all. I feel at peace,” blah, blah, blah. And then I passed out and I woke up. But I didn’t think… I actually thought, when I went to pass out, I thought there was a coin toss for me. So I really felt like I was confronting the end there.

Maybe Greenland. I think of Greenland because I think of those Vikings that settled, there were rugged capable dudes and they didn’t make it. But there are Inuit, natives that live up there, but it’s a hard life and the population’s never grown very big, because you’re scraping by up there. And you picture, and the Vikings that did land there, they just weren’t able to quite adapt. The fact that they all died out is just a symbol to that must be a pretty difficult place to live.

The food sources are limited, but the fact that some people can live there means it is possible. They’ve figured out ways to catch seals and do things to survive, but it’s by no means easier to be taken for granted or obvious. I think it’s probably a harsh place to try to live.

Yeah, it’s fascinating not just humans, but to watch how animals have figured out how to survive. I was watching a documentary on polar bears. They just figure out a way, and they’ve been doing it for generations, and they figure out a way. They travel hundreds of miles to the water to get fat, and they travel 100 miles for whatever other purpose because they want to stay on the ice. I don’t know. But there’s a process, and they figure it out against the long odds, and some of them don’t make it.

The thing that I’ve confronted that I thought I knew was that if I knew I was the last person on earth, I wouldn’t do it. But maybe you’re right. Maybe I would think I wasn’t. But I think I can’t imagine. We’re so blessed in the time we live, but I can’t imagine what it’s like to lose your kids, something like that. It was an experience that was so common for humanity for so much of history.

I don’t know what it would be. So I’m alone. So if I’m alone, I knew, and ultimately it is a game show. So it’s like ultimately, I wasn’t going to kill myself out there.
So if I hadn’t been able to procure food, and I was starving to death, it’s like, okay, I’m going to go home. But if you put yourself in that situation, but it’s not a game show, and having been there to some degree, I will say I wasn’t even close. I don’t even know. It hadn’t pushed my mental limit at all yet I would say or on the scale, but that’s not to say there isn’t one. I know there is one, but I have a hard time…
I know I’ve dealt with enough pain and enough discomfort in life that I know I can deal with that. I think it gets difficult when there’s a way out, and you start to wonder if you shouldn’t take the way out as far as if there’s no way out, I don’t know-
Lex Fridman
Oh, that’s interesting. I mean that is a real difficult battle when there’s an exit, when it’s easy to quit.

It’s not insignificant. If you think you’re doing permanent damage to your body, you would be smart to quit. You should just not do that when it’s not necessary, because health is kind of all you have in some regards. So I don’t blame anyone when they quit because of that reason. It’s like good.

But if you’re in a situation and you don’t have the option to quit, is knowing that you’re doing permanent, that’s not going to break. That won’t break me. You just have to get through it. I’m not sure what my mental limit would be outside of the family suffering in the way that I described earlier.

Isn’t it weird how, I can have a good life, happy life, and then you have a bad back or you have a headache. And it’s amazing how much that can overwhelm your experience.
And again, that was something I saw in dad that was interesting. How can you find joy in that when you’re just steeped in that all the time? And people, I’m sure listening, there’s a lot of people that do, and talk about the cross to bear, and the hero journey to be good for you for trying to find your way through that.
There was a lady in Russia, Tanya, and she had cancer and recovered, but always had a pounding headache, and she was really joyful, and really fun to be around. And I’m just like, man, you just have to have a really bad headache for today to know how much that throws a wrench in your existence. So all that to say if you’re not right now suffering with blindness or a bad back, it’s like just count your blessings because it’s amazing how complex we are, how well our bodies work. And when they go out of whack, it can be very overwhelming. And they all will at some point. And so that’s an interesting thing to think ahead on how you’re going to confront it. It does keeps you humble, like you said.

You wrote a note on your blog. In 2012, you spent five weeks-ish in the forest alone. I just thought it was interesting, because this is in contrast to on the show Alone, you are really alone, you’re not talking to anybody. And you realize that, you write, “I remember at one point, after several weeks had passed, I wondered into a particular beautiful part of the woods and exclaimed out loud, ‘Wow.’ It struck me that it was the first time I had heard my own voice in several weeks, with no one to talk to.” Did your thoughts go into some deep place?

Yeah, I would say my mental life was really active. When you’re that long alone, I’ll tell you what you won’t have is any skeletons in your closet that are still in your closet. You will be forced to confront every person… I mean it’s one thing if you’ve cheated on your wife or something, but you’ll be confronted with the random dude you didn’t say thank you to and the issue that you didn’t resolve. All this stuff that was long gone will come up, and then you’ll work through it, and you’ll think how you should make it right.

I had a lot of those thoughts while I was out there, and it was so interesting to see what you would just brush over and confront it. Because in our modern world, when you’re always distracted, you’re just never ever going to know until you take the time to be alone for a considerable amount of time.

Mm-hmm. But you know, another really awesome place that blew my mind was New Zealand. That south island of New Zealand was pretty incredible. As far as just stunning stuff to see, that was pretty high up there on the list. But all these places have such unique things about Canada. Where they did Alone, it’s not typically what you’d say, because it’s fairly flat, and cliffy, and stuff. But it really became beautiful to me because I could tap into the richness of the land or the fishing hole thing. It was like that’s a special little spot, something like that.

No, we’re going back this summer. I’m going to take guided trip up there, take a bunch of people. I’m really looking forward to being able to enjoy it without the pressure. It’s going to be a fun trip.

What advice would you give to people in terms of how to be in nature, so hikes to take or journeys to take out of nature where it could take you to that place where the busyness and the madness of the world can dissipate and you can be with it?

Jordan Jonas
Yeah, I think you need a few days probably to really tap into it, but maybe you need to work your way there. It’s awesome to go out on a hike, go see some beautiful little waterfall, or go see some old tree, or whatever it is. But I think just doing it, everybody thinks about doing it. You just really do it, go out.

And then plan to go overnight. Don’t be so afraid of all the potentialities that you delay it inevitably. It’s actually one of the things that I’ve enjoyed the most about guiding people, is giving them the tools so that now they have this ability into the future. You can go out and feel like, “I’m going to pick this spot on the map and go there.” And that’s a tool in your toolkit of life that is I think really valuable, because I think everybody should spend some time in nature. I think it’s been pretty proven healthy.
Lex Fridman
Yeah, I mean camping is great. And solo, I got a chance to do it solo, is pretty cool.

So you sit there and you record the thoughts. Actually for having to record the thoughts, it forced me to really think through what I was feeling to convert the feelings into words, which is not a trivial thing because it’s mostly just feeling. You feel a certain kind of way.

That’s interesting. I felt like the way I met my wife was we met at this wedding, and then I went to Russia basically, and we kept in touch via email for that year. And a similar thing. It was really interesting to have to be so thoughtful and purposeful about what you’re saying and things. I think it’s probably a healthy, good thing to do.

Buildings and roads, and food security. And I lived with the natives and I thought to myself a lot, “I wonder if not everybody would choose this way of life,” because there’s something really rich about just that small group, your direct relationship to your needs, all that. But with the food security and the modern medicine, the things that we now have that we take for granted, but that I wouldn’t choose that life if we didn’t have those things, because otherwise you’re going to watch your family starve to death or things like that.

So we have so much now, which should lead us to be hopeful while we try to improve, because there’s definitely a lot of things wrong. But I guess there’s a lot of room for improvement, and I do feel like we’re sort of walking on a knife’s edge, but I guess that’s the way it is.

Yeah, exactly. Knife is getting sharper and sharper. I’ll argue with my brother about that. Sometimes he takes the more positive view and I’m like, “I mean it’s great. We’ve done great,” but man, more and more people with nuclear weapons and more… It’s just going to take one mistake with the more power.

I think there’s something about the sharpness of the knife’s edge that gets humanity to really focus, and step up, and not screw it up. There is just like you said with the, cold going out into the extreme cold, it wakes you up. And I think it’s the same thing when nuclear weapons, it just wakes up humanity.

And now, let me try a new thing where I try to articulate some things I’ve been thinking about, whether prompted by one of your questions or just in general. If you’d like to submit a question including in audio and video form, go to lexfridman.com/ama.
Now allow me to comment on the attempted assassination of Donald Trump on July 13th. First, as I’ve posted online, wishing Donald Trump good health after an assassination attempt is not a partisan statement. It’s a human statement. And I’m sorry if some of you want to categorize me and other people into blue and red bins. Perhaps you do it because it’s easier to hate than to understand. In this case it shouldn’t matter. But let me say once again that I am not right-wing nor left-wing. I’m not partisan. I make up my mind one issue at a time, and I try to approach everyone and every idea with empathy and with an open mind. I have and will continue to have many long-form conversations with people both on the left and the right.
Now onto the much more important point, the attempted assassination of Donald Trump should serve as a reminder that history can turn on a single moment. World War I started with the assassination of Archduke Franz Ferdinand. And just like that, one moment in history on June 18th, 1914 led to the death of 20 million people, half of whom were civilians.
If one of the bullets on July 13th had a slightly different trajectory, where Donald Trump would end up dying in that small town in Pennsylvania, history would write a new dramatic chapter, the contents of which all the so-called experts and pundits would not be able to predict. It very well could have led to a civil war, because the true depth of the division in the country is unknown. We only see the surface turmoil on social media and so on. And it is events like the assassination of Archduke Franz Ferdinand where we as a human species get to find out what the truth is of where people really stand.
The task then is to try and make our society maximally resilient and robust as such to stabilizing events. The way to do that, I think, is to properly identify the threat, the enemy. It’s not the left or the right that are the “enemy,” extreme division itself is the enemy.
Some division is productive. It’s how we develop good ideas and policies, but too much leads to the spread of resentment and hate that can boil over into destruction on a global scale. So we must absolutely avoid the slide into extreme division. There are many ways to do this, and perhaps it’s a discussion for another time. But at the very basic level, let’s continuously try to turn down the temperature of the partisan bickering and more often celebrate our obvious common humanity.
Now let me also comment on conspiracy theories. I’ve been hearing a lot of those recently. I think they play an important role in society. They ask questions that serve as a check on power and corruption of centralized institutions. The way to answer the questions raised by conspiracy theories is not by dismissing them with arrogance and feigned ignorance, but with transparency and accountability.
In this particular case, the obvious question that needs an honest answer is, why did the Secret Service fail so terribly in protecting the former president? The story we’re supposed to believe is that a 20-year-old untrained loner was able to outsmart the Secret Service by finding the optimal location on a roof for a shot on Trump from 130 yards away, even though the Secret Service snipers spotted him on the roof 20 minutes before the shooting and did nothing about it.
This looks really shady to everyone. Why does it take so long to get to a full accounting of the truth of what happened? And why is the reporting of the truth concealed by corporate government speak? Cut the bullshit. What happened? Who fucked up and why? That’s what we need to know. That’s the beginning of transparency.
And yes, the director of the US Secret Service should probably step down or be fired by the president, and not as part of some political circus that I’m sure is coming. But as a step towards uniting an increasingly divided and cynical nation.
Conspiracy theories are not noise, even when they’re false. They are a signal that some shady, corrupt, secret bullshit is being done by those trying to hold on to power. Not always, but often. Transparency is the answer here, not secrecy.
If we don’t do these things, we leave ourselves vulnerable to singular moments that turn the tides of history. Empires do fall, civil wars do break out, and tear apart the fabric of societies. This is a great nation, the most successful collective human experiment in the history of earth. And letting ourselves become extremely divided risks destroying all of that.
So please ignore the political pundits, the political grifters, clickbait media, outrage fueling politicians on the right and the left who try to divide us. We’re not so divided. We’re in this together. As I’ve said many times before, I love you all.
This is a long comment. I’m hoping not to do comments this long in the future and hoping to do many more. So I’ll leave it here for today, but I’ll try to answer questions and make comments on every episode. If you would like to submit questions, like I mentioned, including audio and video form, go to lexfridman.com/ama, and now let leave you with some words from Ralph Waldo Emerson, ” Adopt the pace of nature. Her secret is patience.” Thank you for listening and hope to see you next time.

She is a truly kind, compassionate, and thoughtful human being. In the past, people have attacked her, in my view, to get indirectly at her dad, Donald Trump, as part of a dirty game of politics and clickbait journalism. These attacks obscured many projects and efforts, often bipartisan, that she helped get done, and they obscured the truth of who she is as a human being. Through all that, she never returned the attacks with anything but kindness and always walked through the fire of it all with grace. For this, and much more, she is an inspiration and I’m honored to be able to call her a friend.
Oh, and for those living in the United States, happy upcoming 4th of July. It’s both an anniversary of this country’s Declaration of Independence and an anniversary of my immigrating here to the U.S. I’m forever grateful for this amazing country, for this amazing life, for all of you who have given a chance to a silly kid like me. From the bottom of my heart, thank you. I love you all.
This is the Lex Fridman Podcast. To support it, please check out our sponsors in the description. And now, dear friends, here’s Ivanka Trump.
You said that ever since you were young, you wanted to be a builder, that you loved the idea of designing beautiful city skylines, especially in New York City. I love the New York City skyline. So, describe the origins of that love of building.
With architecture, there’s the tangible, and I think that marriage of function and something that exists beyond yourself is very compelling. I also grew up in a family where my mother was in the real estate business, working alongside my father. My father was in the business. And I saw the joy that it brought to them. So, I think I had these natural positive associations. They used to send me as a little girl, renderings of projects they were about to embark on with notes, asking if I would hurry up and finish school so I could come join them.
So, I had these positive associations, but it came from something within myself. I think that as I got older and as I got involved in real estate, I realized that it was so multidisciplinary. You have, of course, the design, but you also have engineering, the brass tacks of construction. There’s time management, there’s project planning. Just the duration of time to complete one of these iconic structures, it’s enormous. You can contribute a decade of your life to one project. So, while you have to think big picture, it means you really have to care deeply about the details because you live with them. So, it allowed me to flex a lot of areas of interest.
When I look at New York, I see this unbelievable sort of tapestry of different types of architecture. So, you have the Gothic form as represented by buildings like the Woolworth Building. Or, you’ll have Art Deco as represented by buildings like 40 Wall Street or the Chrysler Building or Rockefeller Center. And then, you’ll have these unbelievable super modern examples, or modernist examples like Lever House and Seagram’s House. So, you have all of these different styles, and I think to build in New York, you’re really building the best of the best. So, nobody’s giving New York their second-rate work.
And especially when a lot of those buildings were built, there was this incredible competition happening between New York and Chicago for kind of dominance of the sky and for who could create the greatest skyline, that sort of race to the sky when skyscrapers were first being built, starting in Chicago and then, New York surpassing that in terms of height, at least, with the Empire State Building.
So, I love contextualizing the skylines as well, and thinking back to when different components that are so iconic were added and the context in which they came into being.
But glass is tricky. You have to get the shade right. Some glass has a lot of iron in it and gets super green, and that’s a choice. And sometimes you have more blue properties, blue-silver, like you see here, but it’s part of the character.
The goal is actually that the end result is much, much more compelling than what the architect or artist rendered. But oftentimes, that’s very much not the case. Sometimes also, you mentioned context, sometimes I’ll see renderings of buildings, I’m like, wait, what about the building right to the left of it that’s blocking 80% of its views of the … Architects, they’ll remove things that are inconvenient. So, you have to be rooted in-
I think there’s something really cool happening now with the rediscovery of ancient building techniques. So, you have self-healing concrete that was used by the Romans. An art and a practice of using volcanic ash and lime that’s now being rediscovered and is more critical than ever as we think about how much of our infrastructure relies on concrete and how much of that is failing on the most basic level. So, I think actually, it’s a really, really exciting time for innovation in architecture. And I think there are some incredible examples of modern design that are really exciting. But generally, I think Roosevelt said that, “Comparison is the thief of joy.” So, it’s hard. You look at the Tribune Building, you look at some of these iconic structures. One of the buildings I’m most proud to have worked on was the historical Old Post Office building in Washington D.C. You look at a building like that and it feels like it has no equal.
So, having been able to build so many things in my career and worked on so many incredible projects, I mean, it’s really, really rewarding after the fact, to have somebody come up to you and tell you that they got engaged in the lobby of your building or they got married in the ballroom, and share with you some of those experiences. So, to me, that’s equally as beautiful, the use cases for these unbelievable projects. But I think it’s all of it. I love that you’ve got the construction and you’ve got the design, and you’ve got then the interior design, and you’ve got the financing elements, the marketing elements, and it’s all wrapped up in this one effort. So, to me, it’s exciting to sort of flex in all of those different ways.
So, having the opportunity to spearhead a project like that was so exciting. And actually, it was my first renovation project, so I came to it with a tremendous amount of energy, vigor and humility about how to do it properly. Ensuring I had all the right people. We had countless federal and local government agencies that would oversee every single decision we made. But in advance of even having the opportunity to do it, there was a close to two-year request for proposal, like a process that was put out by the General Services Administration. So, it was this really arduous government procurement process that we were competing against so many different people for the opportunity, which a lot of people said it was a gigantic waste of time. But I looked at that and I think so did a lot of the other bidders and say, “It’s worth trying to put the best vision forward.”
But I think the biggest challenge in having such a radical use conversion is just how you lay it out. So, the amount of time … I would get on that Acela twice a week, three times a week, to spend day trips down in Washington. And we would walk every single inch of the building, laying out the floor plans, debating over the configuration of a room. There were almost 300 rooms, and there were almost 300 layouts. So, nothing could be repeated. Whereas, when you’re building from scratch, you have a box and you decide where you want to add potential elements, and you kind of can stack the floor plan all the way up. But when you’re working within a building like this, every single room was different. You see the setbacks. So, the setback then required you to move the plumbing.
So, it was really a labor of love. And to do something like this … And that’s why I think renovation … We had it with Doral as well. It was 700 rooms, over 650 acres of property. And so, every single unit was very different and complicated. Not as complicated, in some ways, the scale of it was so massive, but not as complicated as the Old Post Office. But it required a level of precision. And I think in real estate, you have a lot of people who design on plan and a lot of people who are in the business of acquiring and flipping. So, it’s more financial engineering than it is building. And they don’t spend the time sweating these details that make something great and make something functional. And you feel it in the end result. But I mean, blood, sweat, tears, years of my life for those projects, and it was worth it. I enjoyed, almost, I enjoyed almost every minute of it.
So for her to have lived through that, she didn’t come to North America until she was 23 or 24, so that was her life. As a young girl, she was on the junior national Ski team for Czechoslovakia. My grandfather used to train her. They used to put the skis on her back and walk up the mountain in Czechoslovakia because there were no ski lifts. She actually made me do that when I was a child just to let me know what her experience had been. If I complained that it was cold out, she’s like, “Well, you didn’t have to walk up the mountain. You’d be plenty warm if you had carried the skis up on your back, up the last run.”
So she was able to travel, where most of her friends never would be able to leave Czechoslovakia, and she would come back from all of these trips where she’d do ski races in Austria and elsewhere, and the first thing she had to do was check in at the local police. And she’d sit down, and she had enough wisdom at 14 to know that she couldn’t appear to be lying by not being impressed by what she saw and the fact that you could get an orange in the winter, but she couldn’t be too excited by it that she’d become a flight risk.
I loved the fact that she so embodied femininity and glamour and was so comfortable being tough and ambitious and determined and this unbelievable businesswoman and entrepreneur at a time when she was very much alone, even for me in the development world. And so many of the different businesses that I’ve been in, there really aren’t women outside of sales and of marketing. You don’t see as many women in the development space, in the construction space, even in the architecture and design space, maybe outside of interior design. And she was decades ahead of me, so I love hearing these stories. I love hearing somebody who’s my peer tell me about their grandfather and their father and their experience with one of my parents. It’s amazing.
And I remember I used to shower and it would almost be comical. I feel like in my memory, and there was no washing machine I’ve seen on the planet that can actually do this, but in my memory, I’d go to shower and I dropped something on the bed and I’d come back into the room after my shower and it was folded, pressed. It was all my grandmother. She was running after me, taking care of me, and so it’s nice to be able to do that for her.
But one of the first time he visits, we’re walking the hallway and we’re talking about how expensive this cooling system would be and heating system would be. And he starts stopping and he’s asking duct workers as we walk what they think of the system that the mechanical engineers designed. First few, fine, not great answers. The third guy goes, “Sir, if you want me to be honest with you, it’s obscenely over-designed. In the circumstance of a 1000-year storm, you will have the exact perfect temperature, if there’s a massive blizzard or if it’s unbearably hot, but 99.9% of the time you’ll never need it. And so I think it’s just an enormous waste of money.” And so he kept asking that guy questions, and we ended up overhauling the design pretty well into the process of the whole system, saving a lot of money, creating a great system that’s super functional.
And so I learned a lot, and that’s just one example of countless. That one really sticks out of in my head because I’m like, “Oh my gosh, we’re redesigning the whole system.” We were actively under construction. But I would see him do that on a lot of different issues. He would ask people on the work level what their thoughts were. Ideas, concepts, designs. And there was almost like a Socratic first principles type of way he questioned people, trying to get down to trying to reduce complex things to something really fundamental and simple. So I try to do that myself to the best I can, and I think it’s something I very much learned from him.
Yeah. It’s interesting. You see this in government. A lot of people get together, a hierarchy is developed, and sometimes it’s good, but very often just slows things down. And you see great companies, great, great companies, Apple, Google, Meta, they have to fight against that bureaucracy that builds, the slowness that large organizations have. And to still be a big organization and act like a startup is the big challenge.
He actually had showed me a building to buy. His family had some real estate holdings and I passed on the real estate deal. But we forged a friendship and we started talking about how in the space that he was in, fine jewelry, there was this lack of product and brands that were positioned for self-purchasing females. So everything was about the man buying the Christmas gift, the man buying the engagement ring. The stores felt like that they were all tailored towards the male aesthetic. The marketing felt like that. And what about the woman who had a salary and was really excited to buy herself a great pair of earrings or had just received a great bonus and was going to use it to treat herself? So we thought there was a void in the marketplace, and that was the first category. I launched Ivanka Trump Fine Jewelry, and we just caught lightning in a bottle.
It was really quickly after that I met my partner who had founded Nine West Shoes, really capable partner, and we launched a shoe collection which took off and did enormously well and then a clothing collection and handbags and sunglasses and fragrance. So we caught a moment and we found a positioning for the self-purchasing multidimensional woman. And we made dressing for work aspirational. At the time, we launched if you wanted to buy something for an office context, the brands that existed were the opposite of exciting. Nobody was taking pictures of what they were wearing to work and posting it online with some of these classic legacy brands. Really, it felt very much like it was designed by a team of men for what a woman would want to wear to the office. So we started creating this clothing that was feminine, that was beautiful, that was versatile, that would take a woman from the boardroom to an after-school soccer game to a date night with a boyfriend, to a walk in the park with their husband.
All the different ways women live their lives and creating a wardrobe for that woman who works at every aspect of their life, not just sort of the siloed professional part. And it was really compelling. We started creating great brand content and we had incredible contributors like Adam Grant who was blogging for us at the time and creating aspirational content for working women. It was actually kind of a funny story, but I now had probably close to 11 different product categories and we were growing like wildfire and I started to think about what would be a compelling way to create interesting content for the people who were buying these different categories. And we came up with a website called Women Who Work, and I went to a marketing agency, one of the fancy firms in New York, and I said, “We want to create a brand campaign around this multidimensional woman who works and what do you think? Can you help us?” And they come back and they say, “You know what? We don’t like the word work. We think it should be women who do.”
And I just start laughing because I’m like women who do. And the fact that they couldn’t conceive of it being sort of exciting and aspirational and interesting to sort of lean into working at all aspects of our lives was just fascinating to me, but showed that that was part of the problem. And I think that’s why ultimately, I mean when the business grew to be hundreds of millions of dollars in sales, we were distributed at all the best retailers across the country from Neiman Marcus, to Saks to Bloomingdale’s and beyond. And I think it really resonated with people in an amazing way and probably not dissimilar to how I have this incredible experience every time somebody comes up to me and tells me that they were married in a space that I had painstakingly designed, I have that experience now with my fashion company. The number of women who will come up tell me that they loved my shoes or they loved the handbags, and I’ve had women show me their engagement rings. They got engaged with us and it’s really rewarding. It’s really beautiful.
So in the beginning, it was much more collaborative. As time passed, I really sort of took the point on deciding, this is the aesthetic for the season, these are the colors we’re going to use, these are fabrics, and then working with our partners on the execution of that. But I needed to create an overlay that allowed for cohesion as the collection grew. And that was actually really fun for me because that was a little different. I was typically initially responding to things that were put in front of me, and towards the end it was my partners who were responding to the things that myself and my team… But I always wanted to bring the best talent in. So I was hiring great designers and printmakers and copywriters. And so I had this almost like… That conductor analogy. I had this incredible group of, in this case, women assembled who had very strong points of view themselves and it created a great team.
And I think somehow early on I learned to kind of harness the fear of not being good enough, not being competent enough, and I harnessed it to make me better and to push me outside of my comfort zone. So I think that’s always lived with me, and I think it probably always will. I think you have to have humility in anything you do that you could be better and strive for that. I think as you get older, it softens a little bit as you have more reps, as you have more examples of having been thrown in the deep end and figured out how to swim. You get a little bit more comfortable in your abstract competency. But if that fear is not in you, I think you’re not challenging yourself enough.
A lot of the tasks were very marketing oriented because of the short duration of time they had to execute. You learned a lot about time management because of that short duration. So almost every episode would devolve into people hysterical over the fact that they had 10 minutes left with this Herculean lift ahead of them. So it was a fascinating experience for me. And we would be filming… I mean, we would film first thing in the morning at 5 or 6 AM in Trump Tower, oftentimes. In the lobby of Trump Tower, that’s where the war rooms and boardrooms of the candidates were, the contestants were. And then we would go up in the elevator to our office. We would work all day, and then we’d come down and we’d evaluate the task. It was this weird real life television thing experience in the middle of our… Sort of on the bookends of our work day. So it was intense.
So, I’ve been stuck there while four or five, six waves just crash on top of your head. And the worst thing you can do is get reactive and scared, and try and fight against it. You just have to flow with it until inevitably there’s a break and then paddle like hell back out to the line, or to the beach, whatever you’re feeling. But to me that’s the hardest part, the paddling out.
But I think then the process that unfolded over the next couple of years was also the most extraordinary growth experience of my life. Suddenly, I was going into communities that I probably never would have been to, and I was talking with people who in 30 seconds would reveal to me their deepest insecurity, their gravest fear, their wildest ambitions, all of it, with the hope that in telling me that story, it would get back to a potential future President of the United States and have impacts for their family, for their community.
So, the level of candor and vulnerability people have with you is unlike anything I’ve ever experienced. And I had done The Apprentice before, people may know who I was in some of these situations that I was going into, but they wouldn’t have shared with me these things that you got the impression that oftentimes their own spouses wouldn’t know, and they wouldn’t do so within 30 seconds. So you learn so much about what motivates people, what drives people, what their concerns are, and you grow so much as a result of it.
And at least at that time, I wonder what it is now, but at that time, I don’t remember. On the surface, there’s political divisions, there’s Republicans and Democrats, and so on, but underneath it people were all the same. The concerns were all the same, there was not that much of a division. Right now, the surface division has been amplified even more maybe because of social media, I don’t know why. So, I would love to see what the country’s like now. But I suspect probably it’s still not as divided as it appears to be on the surface, what the media shows, what the social media shows. But what did you experience in terms of the division?
But I do think you think about the vitriol and politics and whether it’s worse than it’s been in the past or not, I think that’s up for debate. I think there have been duels, there’s been screaming, and politics has always been a blood sport, and it’s always been incredibly vicious. I think in the toxic swirl of social media it’s more amplified, and there’s more democratization around participating in it perhaps, and it seems like the voices are louder, but it feels like it’s always been that. But I don’t believe most people are like that. And you meet people along the way and they’re not leading with what their politics are. They’re telling you about their hopes for themselves and their communities. And it makes you feel that we are a whole lot less divided than the media and others would have us believe.
I look at the surface division, the surface bickering, and that might be just a feature of democracy. It’s not a bug of democracy, it’s a feature. We’re in a constant conflict, and it’s the way we resolve, we try to figure out the right way forward. So in the moment, it feels like people are just tearing each other apart, but really we’re trying to find a way, where in the long arc of history it will look like progress. But in the short term, it just sounds like people making stories up about other and calling each other names, and all this kind of stuff, but there’s a purpose to it. I mean, that’s what freedom looks like, I guess is what I’m trying to say, and it’s better than the alternative.
But when my father won, he asked Jared and I to join him. And in asking that question, keep in mind he was just a total outsider, so there was no bench of people as he would have today. He had never spent the night in Washington DC before staying in the White House. And so, when he asked us to join him, he trusted us. He trusted in our ability to execute. And there wasn’t a part of me that could imagine the 70 or 80-year-old version of myself looking back and having been okay with having said no, and going back to my life as I knew it before. I mean, in retrospect, I realize there is no life as you know it before, but just the idea of not saying yes, wherever that would lead me. And so I dove in.
I was also, during the course of the campaign, I was just much more sensitive to the problems and experiences of Americans. I gave you an example before of the father in New Hampshire, but even just in my consumption of information. I had a business that was predominantly young women, many of which were thinking about having a kid, had just had a child, were planning on that life event. And I knew what they needed to be able to show up every day and realize this dream for themselves and the support structures they would need to have in place.
And I remember reading this article at the time in one of the major newspapers of a woman, she had had a very solid job working at one of the blue chip accounting firms. And the recession came, she lost her job around the same time as her partner left her. And over a matter of months, she lost her home. So, she wound up with her two young kids, after bouncing around between neighbors living in their car. She gets a callback from one of the many interviews she had done for a second interview where she was all but guaranteed the job should that go well, and she had arranged childcare for her two young children with a neighbor in her old apartment block.
And the morning of the interview, she shows up and the neighbor doesn’t answer the doorbell. And she stands there five, 10 minutes, doesn’t answer. So she has a choice: does she go to the interview with her children, or does she try to cancel? She gets in her car, drives to the interview, leaves her two children in the backseat of the car with the window cracked, goes into the interview and gets pulled out of the interview by police because somebody had called the cops after seeing her children in the backseat of the car. She gets thrown in jail, her kids get taken from her, and she spends years fighting to regain custody.
And I think about, that’s an extreme example, but I think about something like that. And I say, “If I was the mother and we were homeless, would I have gone to that interview?” And I probably would have, and that is not an acceptable situation. So you hear stories like that, and then you get asked, “Will you come with me?” And it’s really hard to say no. I spent four years in Washington. I feel like I left it all in the field. I feel really good about it, and I feel really privileged to have been able to do what I did.
What was it like trying to get stuff done in Washington in this place where politics is a game? It feels that way maybe from an outsider perspective. And you go in there trying, given some of those stories, trying to help people. What’s it like to get anything done?
One of the first experiences I had where it really was just a full grind effort was with tax cuts and the work I did to get the child tax credit doubled as part of it. And it just meant meeting, after meeting, after meeting, after meeting with lawmakers, convincing them of why this is good policy, going into their districts, campaigning in their districts, helping them convince their constituents of why it’s important, of why childcare support is important, of why paid family leave is important, of different policies that impact working American families. So it’s hard, but it’s really rewarding.
And then to get it done, I mean, just the child tax credit alone, 40 million American families got an average of $2,200 each year as a result of the doubling of the child tax credits. That was one component of tax cuts.
I remember visiting with a woman, Brittany Houseman, she came to the White House. She had two small children, she was pregnant with her third. Her husband was killed in a car accident. She was in school at the time. Her dream was to become criminal justice advocate. That was no longer on the table for her after he passed away and she became the sole earner and provider for her family. And she couldn’t afford childcare, she couldn’t afford to stay in school, so she ended up creating a child childcare center in her home.
And her center was so successful because in part of different policies we worked on, including the childcare block grants that went to the state. She ended up opening additional centers, I visited her at one of them in Colorado. Now she has a huge focus on helping teenage moms who don’t have the resources to afford quality childcare for their kids come into her centers and programs. And it’s stories like that of the hardships people face, but also what they do with opportunity when they’re given it, that really powers you through tough moments when you’re in Washington.
And so that, and then we also put in place the first ever national tax credit for workers making under $72,000 a year where employers could then offer it to their workers. That was also part of tax cuts. So part of it is really taking the arguments as to why this is good, smart, well-designed policy to people. And it was one of my big surprises that on certain policy issues that I thought would have been well socialized, the policies that existed were never shared across the aisle. So people just lived with them maybe in hopes that one day …
So I think part of it is be willing to have those tough discussions with people who may not share your viewpoint and be an active listener when they point out flaws and they have suggestions for changes, not believing that you have a monopoly on good ideas. And I think there has to be a lot of humility in architecting these things. And a policy should benefit from that type of well-rounded input.
Modernizing Perkins CTE in vocational education. And it’s something I became super passionate about and help lead the charge on. I think in America for a really long period of time, we’ve really believed that education stops when you leave high school or college. And that is not true and that’s a dangerous way to think. So how can we both galvanize the private sector to ensure that they continue to train workers for the jobs they know are coming and how they train their existing workforce into the new jobs with robotics or machinery or new technologies that are coming down the pike. So galvanizing the private sector to join us in that effort.
So whether it’s the legislative side, like the actual legislation of Perkins CTE, which was focused on vocational education or whether it’s the ability to use the White House to galvanize the private sector, we got over 16 million commitments from the private sector to retrain or re-skill workers into the jobs of tomorrow.
Human trafficking. That’s an issue that I didn’t go to the White House thinking I would work on, but you hear a story of a survivor and you can’t not want to eradicate one of the greatest evils that the mind can even imagine. The trafficking of people, the exploitation of children. And I think for so many they assume that this is a problem that doesn’t happen on our shores. It’s something that you may experience at far-flung destinations across the world, but it’s happening there and it’s happening here as well.
And so through a coalition of people that on both sides of the aisle that I came to trust and to work well with, we were able to get legislation which the president signed, passed nine pieces of legislation, combating trafficking at home and abroad and digital exploitation of children.
So we did a lot with DOJ around changing that, but now she’s helping other survivors get skills and job training and the therapeutic interventions they need. But you speak with people like Andrea and so many others, and I mean you can’t not, your heart gets seized by it and it’s both, it’s motivating and it’s hard. It’s really hard.
But the people that really feel the humanity of that, feel the pain of that are probably the right people to be politicians. But it’s probably also why you can’t stay in there too long.
I think a better way to frame it is, am I living in accordance with my priorities? Maybe not every day, but every week, every month. And reflecting on have you architected a life that aligns with your priorities so that more often than not you’re where you need to be in that moment. And service at that level was the one time where you really you feel incredibly conflicted about having any priorities other than serving. It’s finite.
In every business I’ve built, you’re building for duration. And then you go into the White House and it is sand through an hourglass. Whether it’s four years or eight years, it’s a finite period of time you have. And most people don’t last four years. I think the average in the White House is 18 months. It’s exhausting. But it’s the only time when you’re at home with your own children that you feel, you think about all the people you’ve met and you feel guilty about any time that’s spent not advancing those interests to the best of your capacity.
And that’s a hard thing. That’s a really hard feeling as a parent. And it’s really challenging then to be present, to always need to answer your phone, to always need to be available. It’s very difficult, it’s taxing, but it’s also the greatest privilege in the world.
I still remember Theo when he was around three, three and a half years old. Jared used to make me coffee every morning and it was like my great luxury that I would sit there. He still makes it for me every morning. I told him, I’m never, even though I secretly know how to actually work the coffee machine, but I’ve convinced him that I have no idea how to work the coffee machine. Now I’m going to be busted, but it’s a skill I don’t want to learn because it’s one of his acts of love. He brings me coffee every morning in bed while I read the newspapers.
And Theo would watch this. And so he got Jared to teach him how to make coffee. And Theo learned how to make a full-blown cappuccino.
I think for me though, they’ve also been some of my greatest teachers in that we were talking about the presence you felt when you were in the jungle and the connectivity you felt and sort of the simple joy. And I think for us as we grow older, we kind of disconnect from that. My kids have taught me how to play again. And that’s beautiful. I remember just a couple of weeks ago we had one of these crazy Miami torrential downpours and Arabella comes down, it’s around eight o’clock at night, it’s really raining. And she’s got rain boots and pajama pants on, and she’s going to take the dogs for a walk in the rain, which she had all day to walk, but she wasn’t doing it because they needed to go for a walk. She was like, “This would be fun.”
And I’m standing at the doorstep watching her and she goes out with Simba and Winter, this massive dog and this little tiny dog. And I’m watching her walk to the end of the driveway and she’s just dancing. And it’s pouring. And I took off my shoes and I went out and I joined her and we danced in the rain. And even as a preteen who normally she allowed me to experience the joy with her, and it was amazing.
We can be so much more fun if we allow ourselves to be more playful. We can be so much more present. I look at, Theo loves games, so we play a whole lot of board games, any kind of game. So it started with board games. We do a lot of puzzles. Then it became card games. I just taught him how to play poker.
So those kids have taught me so much about sort of reconnecting with what’s real and what’s true and being present in the moment and experiencing joy.
And it’s interesting what you said that the puzzle of noticing each human being, what makes them beautiful, the unique characteristics, what they’re good at, the way they want to be mentored. I often see that, especially with coaches and athletes, young athletes aspiring to be great. Each athlete needs to be trained in a different way. For example, with some, you need a softer approach. With me, I always like a dictatorial approach. I like the coach to be this menacing figure. That’s what brought out the best in me. I didn’t want to be friends with the coach. I wanted almost, it’s weird to say, but yelled at to be pushed. But that doesn’t work for everybody. And that’s a risk you have to take in the coach context of, because you can’t just yell at everybody. You have to figure out what does each person need. And when you have kids, I imagine the puzzle is even harder.
Especially when I’ve been working really hard and in the White House, I’d say, “Okay, well now we have a Sunday and we have these hours,” and I’ll have a grand plan and we’re going to make a count and it’s going to involve hot chocolate and sleds, whatever it is that my great adventure that we’re going to go play mini golf. And then I come down all psyched up, all ready to go, and the kids have zero interest. And there have been a lot of times where I’ve been like, “We’re doing this thing.” And then I realized, “Wait a second.” Sometimes you just plop down on the floor and start playing magnet tiles and that’s where they need you.
So those of us who have sort of alpha personalities who sometimes it’s just witness, witness what they need. Play with them and allow them to lead the play. Don’t force them down a road you may think is more interesting or productive or educational or edifying. Just be with them, observe them, and then show them that you are genuinely curious about the things that they are genuinely curious about. I think there’s a lot of love when you do that.
It’s really hard when you try to navigate something because everyone thinks you’re taking their sides. You have oftentimes incomplete information. I think for parents, what tends to happen too is we see our kids fighting with each other in a way that all kids do and we start to project into the future and catastrophize. If my two sons are going through a moment where they’re like oil and water, anything one wants to do the other doesn’t want to do. It’s a very interesting moment. So my instinct is they’re not going to like each other when they’re 25. You sort of project into the future as opposed to recognizing this is a stage that I too went through, and it’s normal, and it’s not building it in your mind into something that’s unnecessarily consequential.
And I think part of me also internalized, there’s a concept in Judaism called Lashon hara, which is translated into I think quite literally evil speech. And the idea that speaking poorly of another is almost the moral equivalent to murder because you can’t really repair it. You can apologize, but you can’t repair it. Another component of that is that it does as much damage to the person saying the words than it does to the person receiving them. And I think about that a lot. I talk about this concept with my kids a lot, and I’m not willing to pay the price of that fleeting and momentary satisfaction of sort of swinging back because I think it would be too expensive for my soul. And that’s how I made peace with it, because I think that feels more true for me.
But it is a little bit contrary in politics. It’s definitely a contrarian viewpoint to not get into the fray. Actually, some day, I love Dolly Parton says that she doesn’t condemn or criticize. She loves and accepts. And I like that. It feels right for me.
You quoted Alan Watts, I love him, in saying, “You’re under no obligation to be the same person you were five minutes ago.” So how have the years in DC and the years after changed you?
I think further than that, if we don’t look back on who we were a few years ago with some level of embarrassment, we’re not growing enough. So there’s nothing. When I look back, I’m like, oh, I feel like that feeling is because you’re growing into hopefully sort of a better version of yourself. And I hope and feel that that’s been true for me as well. I think the person I am today, we spoke in the beginning of our discussion about some of my earliest ambitions in real estate and in fashion, and those were amazing adventures and incredible experiences in government.
And I feel today that all of those ambitions are more fully integrated into me as a human being. I’m much more comfortable with the various pieces of my personality and that any professional drive is more integrated into more simple pleasures. Everything for me has gotten much simpler and easier in terms of what I want to do and what I want to be. And I think that’s where my kids have been my teachers just being fully present and enjoying the little moments. And it doesn’t mean I’m any less driven than I was before. It’s just more a part of me than being sort of the all-consuming energy one has in their 20s.
Obviously, we talked about the enormity, the scale of what can be accomplished in government service, but I think there’s something equally valuable about helping within your own community. And I volunteer with the kids a lot and we feel really good about that service. It’s different, but it’s no less meaningful. So I think there are other ways to serve. I also think for politics, it’s a pretty dark world. There’s a lot of darkness, a lot of negativity, and it’s just really at odds with what feels good for me as a human being. And it’s a really rough business. So for me and my family, it feels right to not participate.
And I think for young children, it’s very abstract, policy. And so for her to be able to share with them this was a very beautiful moment and led to a lot of really incredible conversations with each of my kids about our time and service because they gave up a lot for me to do it. Actually, Alice told them the most beautiful story about the plays she used to put on in prison, how these shows were the hottest ticket in town. You could not get into them, they always extended their run. But for the people who were in them, a lot of those men and women had never experienced applause. Nobody had ever shown up at their games or at their plays and clapped for them. And the emotional experience of just being able to give someone that, being able to stand and applaud for someone and how meaningful that was. And she was showing us pictures from these different productions and it was a beautiful moment.
Alice actually, after her sentence was commuted and she came out of prison, together, we worked on 23 different pardons or commutations. So the impact of her experience and how she was able to take her opportunity and create that same opportunity for others who were deserving and who she believed in was very beautiful. So anyway, that was an extraordinary concert experience for my kids to be able to have that moment.
And I really dug in on pardons and commutations that I thought were overdue and were worthy. And my last night in Washington, D.C., the gentleman you mentioned, Corvin, I was on the phone with his mother at 12:30 in the morning, telling her that her son would be getting out the next day. And it felt really… It’s one person. But you see with Alice, the ripple effect of the commutation granted to her and her ability and the impact she’ll have within her family, with her grandkids. And now, she’s an advocate for so many others who are voiceless. It felt like the perfect way to end four years, to be able to call those parents and call those kids in some cases and give them the news that a loved one was coming home.
All we hear is.
And I feel like especially everyone’s… You get on an elevator and the first thing people do is pick up their phone. You’re walking down the street, people are getting hit by cars because they’re walking into traffic. I think as you start to get this training, you become much more aware of the broader context of what’s happening around you, which is really healthy and good as well. But it’s been beautiful. Actually, the Valente Brothers, they have this 753code that was developed with some of the samurai principles in mind. And all of my kids have memorized it and they’ll talk to me about it. Theo, he’s eight years old, he’s able to recite all 15. So benevolence and fitness and nutrition and flow and awareness and balance. And it’s an unbelievable thing. And they’ll actually integrate it into conversations where they’ll talk about something that… Yeah, rectitude, courage.
I also told Arabella, we were talking about this archery competition that happens in Mongolia, and she loves horseback riding. So I’m like, I feel like that would be an amazing thing to experience together. I want to get barreled by a wave and learn how to play Texas Flood. I want to see the Northern Lights. I want to go and experience that. I feel like that would be really beautiful. I want to get my black belt.

The following is a conversation with Ivanka Trump, businesswoman, real estate developer, and former senior advisor to the president of the United States. I’ve gotten to know Ivanka well over the past two years. We’ve become good friends, hitting it off right away over our mutual love of reading, especially philosophical writings from Marcus Aurelius, Joseph Campbell, Alan Watts, Victor Franco, and so on.

She is a truly kind, compassionate, and thoughtful human being. In the past, people have attacked her, in my view, to get indirectly at her dad, Donald Trump, as part of a dirty game of politics and clickbait journalism. These attacks obscured many projects and efforts, often bipartisan, that she helped get done, and they obscured the truth of who she is as a human being. Through all that, she never returned the attacks with anything but kindness and always walked through the fire of it all with grace. For this, and much more, she is an inspiration and I’m honored to be able to call her a friend.
Oh, and for those living in the United States, happy upcoming 4th of July. It’s both an anniversary of this country’s Declaration of Independence and an anniversary of my immigrating here to the U.S. I’m forever grateful for this amazing country, for this amazing life, for all of you who have given a chance to a silly kid like me. From the bottom of my heart, thank you. I love you all.
This is the Lex Fridman Podcast. To support it, please check out our sponsors in the description. And now, dear friends, here’s Ivanka Trump.
Architecture
You said that ever since you were young, you wanted to be a builder, that you loved the idea of designing beautiful city skylines, especially in New York City. I love the New York City skyline. So, describe the origins of that love of building.
Ivanka Trump
I think there’s both an incredible confidence and a total insecurity that comes with youth. So, I remember at 15, I would look out over the city skyline from my bedroom window in New York and imagine where I could contribute and add value, in a way that I look back on and completely laugh at how confident I was. But I’ve known since some of my earliest memories, it’s something I’ve wanted to do. And I think fundamentally, I love art. I love expressions of beauty in so many different forms.

But I’ve known since some of my earliest memories, it’s something I’ve wanted to do. And I think fundamentally, I love art. I love expressions of beauty in so many different forms.
With architecture, there’s the tangible, and I think that marriage of function and something that exists beyond yourself is very compelling. I also grew up in a family where my mother was in the real estate business, working alongside my father. My father was in the business. And I saw the joy that it brought to them. So, I think I had these natural positive associations. They used to send me as a little girl, renderings of projects they were about to embark on with notes, asking if I would hurry up and finish school so I could come join them.
So, I had these positive associations, but it came from something within myself. I think that as I got older and as I got involved in real estate, I realized that it was so multidisciplinary. You have, of course, the design, but you also have engineering, the brass tacks of construction. There’s time management, there’s project planning. Just the duration of time to complete one of these iconic structures, it’s enormous. You can contribute a decade of your life to one project. So, while you have to think big picture, it means you really have to care deeply about the details because you live with them. So, it allowed me to flex a lot of areas of interest.
Lex Fridman
I love that confidence of youth.
I love that confidence of youth.
Ivanka Trump
It’s funny because we’re all so insecure, right? In the most basic interactions, but yet, our ambitions are so unbridled in a way that kind of makes you blush as an adult. And I think it’s fun. It’s fun to tap into that energy.

Lex Fridman
Yeah, where everything is possible. I think some of the greatest builders I’ve ever met, kind of always have that little flame of everything is possible, still burning. That is a silly notion from youth, but it’s not so silly. Everybody tells you something is impossible, but if you continue believing that it’s possible and to have that sort of naive notion that you could do it, even if it’s exceptionally difficult, that naive notion turns into some of the greatest projects ever done.

A hundred percent.
A hundred percent.
Lex Fridman
Going out to space or building a new company where like everybody said, it’s impossible, taking on that gigantic company and disrupting them and revolutionizing how stuff is done, or doing huge building projects where, like you said, so many people are involved in making that happen.

We start to become insecure, and we start to rely on the input or validation of others, and it takes us away from that core drive and ambition. So, it’s fun to reflect on that and also to smile, right? Because whether you can execute or not, time will tell. But yeah, no, that was very much my childhood.

Yeah, of course, it’s important to also have the humility of once you get humbled and realize that it’s actually a lot of work to build.

I still am amazed just looking at big buildings, big bridges, that human beings are able to get together and build those things. That’s one of my favorite things about architecture is just like, wow. It’s a manifestation of the fact that humans can collaborate and do something epic, much bigger than themselves, and it’s like a statue that represents that and it can be there for a long time.

It’s a testament to somebody’s dream. Not somebody, a whole ensemble of people’s dreams and visions and triumphs, and in some cases, failures, if the projects weren’t properly executed. So, you look at these skylines, and it’s a testament to that. I actually heard once architecture described as frozen music. That really resonated with me.

Yeah. I remember the first time I went to Dubai and I was watching them dredging out and creating these man-made islands. And I remember somebody once saying to me, they’re an architect, an architect actually who collaborated with us on our tower in Chicago. He said that the only thing that limited what an architect could do in that area was gravity and imagination.

Lex Fridman
Yeah, but gravity is a tricky one to work against, and that’s where civil engineer is one of my favorite things. I used to build bridges in high school for physics classes. You have to build bridges and you compete on how much weight they can carry relative to their own weight. You study how good it is by finding its breaking point. And that was a deep appreciation for me, on a miniature scale of on a large scale, what people are able to do with civil engineering because gravity is a tricky one to fight against.

So, if we think of skylines as ensembles of dreams realized, you spent quite a bit of time in New York. What do you love about and what do you think about the New York City skyline? What’s a good picture? We’re looking here at a few. I mean, looking over the water.

Ivanka Trump
Well, I think the water’s an unbelievable feature of the New York skyline as you see the island on approach. And oftentimes, you’ll see, like in these images, you’ll see these towers reflecting off of the water’s surface. So, I think there’s something very beautiful and unique about that.

When I look at New York, I see this unbelievable sort of tapestry of different types of architecture. So, you have the Gothic form as represented by buildings like the Woolworth Building. Or, you’ll have Art Deco as represented by buildings like 40 Wall Street or the Chrysler Building or Rockefeller Center. And then, you’ll have these unbelievable super modern examples, or modernist examples like Lever House and Seagram’s House. So, you have all of these different styles, and I think to build in New York, you’re really building the best of the best. So, nobody’s giving New York their second-rate work.
And especially when a lot of those buildings were built, there was this incredible competition happening between New York and Chicago for kind of dominance of the sky and for who could create the greatest skyline, that sort of race to the sky when skyscrapers were first being built, starting in Chicago and then, New York surpassing that in terms of height, at least, with the Empire State Building.
So, I love contextualizing the skylines as well, and thinking back to when different components that are so iconic were added and the context in which they came into being.
Lex Fridman
I got to ask you about this. There’s a pretty cool page that I’ve been following on X, Architecture & Tradition, and they celebrate traditional schools of architecture. And you mentioned Gothic, the tapestry. This is in Chicago, the Tribune Tower in Chicago. So, what do you think about that, the old and the new mixed together? Do you like Gothic?

Ivanka Trump
I think it’s hard to look at something like the Tribune Tower and not be completely in awe. This is an unbelievable building. Look at those buttresses and you’ve got gargoyles hanging off of it. And this style was reminiscent of the cathedrals of Europe, which was very in vogue in the 1920s here in America. Actually, I mentioned the Woolworth Tower before. The Woolworth Tower was actually referred to as the Cathedral of Commerce, because it also was in that Gothic style.

So, this was built maybe a decade before the Tribune building, but the Tribune building to me is, it’s almost not replicable. It personally really resonates with me because one of the first projects I ever worked on was building Trump Chicago, which was this beautiful, elegant, super modern, all glass skyscraper, right across the way. So, it was right across the river. So, I would look out the windows as it was under construction, or be standing quite literally on rebar of the building, looking out at the Tribune and incredibly inspired. And now, the reflective glass of the building reflects back not only the river, but also the Tribune building and other buildings on Michigan Avenue.

Do you like it when the reflective properties of the glass is part of the architecture?
Do you like it when the reflective properties of the glass is part of the architecture?
Ivanka Trump
I think it depends. They have super-reflective glass that sometimes doesn’t work. It’s distracting. And I think it’s one component of sort of a composition that comes together. I think in this case, the glass on Trump Chicago is very beautiful. It was designed by Adrian Smith of Skidmore, Owings & Merrill, a major architecture firm who actually did the Burj Khalifa in Dubai, which is, I think, an awe-inspiring example of modern architecture.

But glass is tricky. You have to get the shade right. Some glass has a lot of iron in it and gets super green, and that’s a choice. And sometimes you have more blue properties, blue-silver, like you see here, but it’s part of the character.
Lex Fridman
How do you know what it’s actually going to look like when it’s done? Is it possible to imagine that? Because it feels like there’s so many variables.

Ivanka Trump
I think so. I think if you have a vivid imagination, and if you sit with it, and then if you also go beyond the rendering, right? You have to live with the materials. So, you don’t build a 92-story building glass curtain wall and not deeply examine the actual curtain wall before purchasing it. So, you have to spend a lot of time with the actual materials, not just the beautiful artistic renderings, which can be incredibly misleading.

The goal is actually that the end result is much, much more compelling than what the architect or artist rendered. But oftentimes, that’s very much not the case. Sometimes also, you mentioned context, sometimes I’ll see renderings of buildings, I’m like, wait, what about the building right to the left of it that’s blocking 80% of its views of the … Architects, they’ll remove things that are inconvenient. So, you have to be rooted in-

Modern architecture

One of the underlying principles of the page I just mentioned, and I hear folks mention this a lot, is that modern architecture is kind of boring, that it lacks soul and beauty. And you just spoke with admiration for both modern and for Gothic, for older architecture. So, do you think there’s truth that modern architecture is boring?

I’m living in Miami currently, so I see a lot of super uninspired glass boxes on the waterfront, but I think exceptional things shouldn’t be the norm. They’re typically rare. And I think in modern architecture, you find an abundance of amazing examples of super compelling and innovative building designs. I mean, I mentioned the Burj Khalifa. It is awe-inspiring. This is an unbelievably striking example of modern architecture. You look at some older examples, the Sydney Opera House. And so, I think there’s unbelievable … There you go. I mean, that’s like a needle in the sky.

It’s huge. And in the context of a city where there’s a lot of height. So, it’s unbelievable. But I think one of the things that’s probably exciting me the most about architecture right now is the innovation that’s happening within it. There’s example of robotic fabrication, there’s 3D printing. Your friend and who you introduced me to not too long ago, Neri Oxman, which he’s doing at the intersection of biology and technology and thinking about how to create more sustainable development practices, quite literally trying to create materials that will biodegrade back into the earth.

I think there’s something really cool happening now with the rediscovery of ancient building techniques. So, you have self-healing concrete that was used by the Romans. An art and a practice of using volcanic ash and lime that’s now being rediscovered and is more critical than ever as we think about how much of our infrastructure relies on concrete and how much of that is failing on the most basic level. So, I think actually, it’s a really, really exciting time for innovation in architecture. And I think there are some incredible examples of modern design that are really exciting. But generally, I think Roosevelt said that, “Comparison is the thief of joy.” So, it’s hard. You look at the Tribune Building, you look at some of these iconic structures. One of the buildings I’m most proud to have worked on was the historical Old Post Office building in Washington D.C. You look at a building like that and it feels like it has no equal.
Lex Fridman
Also, there’s a psychological element where people tend to want to complain about the new and celebrate the old.

And it’s true that there’s a lot of stuff that’s new that’s not good, it’s not going to last, it’s not going to stand the test of time, but some things will. And just like in modern art and modern music, there’s going to be artists that stand the test of time and we’ll later look back and celebrate them, “Those were the good times.”

When you just step back, what do you love about architecture? Is it the beauty? Is it the function?
When you just step back, what do you love about architecture? Is it the beauty? Is it the function?
Ivanka Trump
I’m most emotionally drawn, obviously, to the beauty, but I think as somebody who’s built things, I really believe that the form has to follow the function. There’s nothing uglier than a space that is ill-conceived, that otherwise, it’s decoration. And I think that after that initial reaction to seeing something that’s aesthetically really pleasing to me, when I look at a building or a project, I love thinking about how it’s being used.

And I think that after that initial reaction to seeing something that’s aesthetically really pleasing to me, when I look at a building or a project, I love thinking about how it’s being used.
So, having been able to build so many things in my career and worked on so many incredible projects, I mean, it’s really, really rewarding after the fact, to have somebody come up to you and tell you that they got engaged in the lobby of your building or they got married in the ballroom, and share with you some of those experiences. So, to me, that’s equally as beautiful, the use cases for these unbelievable projects. But I think it’s all of it. I love that you’ve got the construction and you’ve got the design, and you’ve got then the interior design, and you’ve got the financing elements, the marketing elements, and it’s all wrapped up in this one effort. So, to me, it’s exciting to sort of flex in all of those different ways.
Lex Fridman
Yeah. Like you said, it’s dreams realized, hard work realized. I mean, probably on the bridge side is why I love the function. In terms of function being primary, you just think of the millions-

Yeah. So, this is probably … Well, we don’t know. We need to interview some people whether the function holds up, but in terms of beauty, and then, what we’re talking about, using the water for the reflection and the shape that it creates, I mean, there’s an elegance to the shape of a bridge.

I mean, those are probably my favorites in the United States. Just in a city, to be able to look out and see the skyline combined with the suspension bridge, and thinking of all the millions of cars that pass, the busyness, us humans getting together and going to work, building cool stuff. And just the bridge kind of represents the turmoil and the busyness of a city as it creates. It’s cool.

And I mean, you actually built many replicas, so I’m sure you’ll have a point of view on this, but they really are so beautiful. And you mentioned the Brooklyn Bridge, but growing up in New York, that was as much a part of the architectural story and tapestry of that skyline as any building that’s seen in it.

Ivanka Trump
Well, some of the most recent projects I worked on prior to government service were the Old Post Office building and almost simultaneously, Trump Doral in Miami. So, these were both two just massive undertakings, both redevelopments, which in a lot of cases, having worked on ground-up construction redevelopment projects, are in a lot of ways much more complicated because you have existing attributes, but also a lot of limitations you have to work within, especially when you’re repurposing a use. So, the Old Post Office building on Pennsylvania Avenue was-

It’s unbelievable. So, this was a Romanesque revival building built in the 1890s on America’s Main Street to symbolize American grandeur. And at the time, there were post office being built in this style across the country, but this being really the defining one. Still to this day, the tallest habitable structure in Washington. The tallest structure being the monument. The nation’s only vertical park, which is that clock tower. But you’ve got these thick granite walls, those carved granite turrets, just an unbelievable building. You’ve got this massive atrium that runs through the whole center of it that is topped with glass.

But you’ve got these thick granite walls, those carved granite turrets, just an unbelievable building. You’ve got this massive atrium that runs through the whole center of it that is topped with glass.
So, having the opportunity to spearhead a project like that was so exciting. And actually, it was my first renovation project, so I came to it with a tremendous amount of energy, vigor and humility about how to do it properly. Ensuring I had all the right people. We had countless federal and local government agencies that would oversee every single decision we made. But in advance of even having the opportunity to do it, there was a close to two-year request for proposal, like a process that was put out by the General Services Administration. So, it was this really arduous government procurement process that we were competing against so many different people for the opportunity, which a lot of people said it was a gigantic waste of time. But I looked at that and I think so did a lot of the other bidders and say, “It’s worth trying to put the best vision forward.”
Lex Fridman
So, you fell in love with this project? This-

So, is there some interesting details about what it takes to do renovation, about some of the challenges or opportunities? Because you want to maintain the beauty of the old and now upgrade the functionality, I guess, and maybe modernize some aspects of it without destroying what made the building magical in the first place.

So, I think the greatest asset was already there, the exterior of the building, which we meticulously restored, and any addition to it had to be done very gently in terms of any signage additions. The interior spaces were completely dilapidated. It had been a post office, then was used for a really rundown food court and government office spaces. It was actually losing $6 million a year when we got the concession to build it and when we won. And became one of, I think, a great example of public-private partnerships working together.

It was actually losing $6 million a year when we got the concession to build it and when we won. And became one of, I think, a great example of public-private partnerships working together.
But I think the biggest challenge in having such a radical use conversion is just how you lay it out. So, the amount of time … I would get on that Acela twice a week, three times a week, to spend day trips down in Washington. And we would walk every single inch of the building, laying out the floor plans, debating over the configuration of a room. There were almost 300 rooms, and there were almost 300 layouts. So, nothing could be repeated. Whereas, when you’re building from scratch, you have a box and you decide where you want to add potential elements, and you kind of can stack the floor plan all the way up. But when you’re working within a building like this, every single room was different. You see the setbacks. So, the setback then required you to move the plumbing.
So, it was really a labor of love. And to do something like this … And that’s why I think renovation … We had it with Doral as well. It was 700 rooms, over 650 acres of property. And so, every single unit was very different and complicated. Not as complicated, in some ways, the scale of it was so massive, but not as complicated as the Old Post Office. But it required a level of precision. And I think in real estate, you have a lot of people who design on plan and a lot of people who are in the business of acquiring and flipping. So, it’s more financial engineering than it is building. And they don’t spend the time sweating these details that make something great and make something functional. And you feel it in the end result. But I mean, blood, sweat, tears, years of my life for those projects, and it was worth it. I enjoyed, almost, I enjoyed almost every minute of it.
Lex Fridman
So, to you, it’s not about the flipping, to you, it’s about the art and the function of the thing that you’re creating?

Ivanka Trump
When proposals are put forth by an architect and really just the plan is accepted without … And in the case of a renovation, if you’re not walking those rooms … The number of times a beautifully laid out room was on a blueprint and then, I’d go to Washington and I’d walk that floor and I’d realize that there was a column that ran right up through the middle of the space where the bed was supposed to be, or the toilet was supposed to be, or the shower. So, there’s a lot of things that are missed when you do something conceptually without rooting it in the actual structure. And that’s why I think even with ground-up construction as well, people who aren’t constantly on their job sites, constantly walking the projects, there’s a lot that’s missed.
When proposals are put forth by an architect and really just the plan is accepted without … And in the case of a renovation, if you’re not walking those rooms … The number of times a beautifully laid out room was on a blueprint and then, I’d go to Washington and I’d walk that floor and I’d realize that there was a column that ran right up through the middle of the space where the bed was supposed to be, or the toilet was supposed to be, or the shower. So, there’s a lot of things that are missed when you do something conceptually without rooting it in the actual structure. And that’s why I think even with ground-up construction as well, people who aren’t constantly on their job sites, constantly walking the projects, there’s a lot that’s missed.

I mean, there’s a wisdom to the idea that we talked about before, live with the materials and walking the construction site, walking the rooms. I mean, that’s what you hear from people like Steve Jobs, like Elon. That’s why you live on the factory floor. That’s why you constantly obsess about the details of the actual, not of the plans, but the physical reality of the product. I mean, the insanity of Steve Jobs and Jony Ive working together on making it perfect, making the iPhone, the early designs, prototypes, making that perfect, what it actually feels like in the hand. You have to be there as close to the metal as possible to truly understand.

Because for the most part, you can probably get 90, maybe even 95% of the end result, unless something has terribly gone awry, by not caring with that level of almost like maniacal precision. But you’ll notice that 10% for the rest of your life. So, I think that extra effort, that passion, I think that’s what separates good from great.

So much. She passed away two years ago now. And she was a remarkable, remarkable woman. She was a trailblazer in so many different ways, as an athlete and growing up in communist Czechoslovakia, as a fashion mogul, as a real estate executive and builder. Just this all-around trailblazing businesswoman. I also learned from her, aside from that element, how to really enjoy life. I look back and some of my happiest memories of her are in the ocean-

… memories of her are in the ocean, just lying on our back, looking up at the sun and just so in the moment or dancing. She loved to dance, so she really taught me a lot about living life to its fullest. And she had so much courage, so much conviction, so much energy, and a complete comfort with who she was.

What do you think about that? Olympic athlete. The trade-off between ambition and just wanting to do big things and pursuing that and giving your all to that, and being able to relax and just throw your arms back and enjoy every moment of life.

I think because she was this unbelievable, formidable athlete and because of the discipline she had as a child, I think it made her value those moments more as an adult. I think she was a great balance of the two that we all hope to find, and she was able to find both incredibly serious and formidable. I remember as a little girl, I used to literally traipse behind her at the Plaza Hotel, which she oversaw and actually was her old post office. It was this unbelievable historic hotel in New York City, and I’d follow her around at construction meetings and on job sites. And there she is, dancing. See? That’s funny that that’s the picture you pull up.

That’s great. She had such a joy to her and she was so unabashed in her perspective and her opinions. She made my father look reserved, so whatever she was feeling, she was just very expressive and a lot of fun to be around.

So she, as you mentioned, grew up during the Prague Spring in 1968, and that had a big impact on human history. My family came from the Soviet Union. And then the story of the 20th century is a lot of Eastern Europe, the Soviet Union, tried the ideas of communism, and it turned out that a lot of those ideas resulted into a lot of suffering. So why do you think the communist ideology failed?

I think fundamentally as people, we desire freedom. We want agency. And my mom was like a lot of other people who grew up in similar situations where she didn’t like to talk about it that often, so one of my real regrets is that I didn’t push her harder. But I think back to the conversations we did have, and I try to imagine what it’s like. She was at Charles University in Prague, which was really a focal point of the reforms that were ushered in during the Prague Spring and the liberalization agenda that was happening. The dance halls were opening, the student activists, and she was attending university there right at that same time. So the contrast to this feeling of freedom and progress and liberalization in the spring, and then it so quickly being crushed in the fall of that same year when the Warsaw Pact countries and the Soviet Union rolled in to put down and ultimately roll back all those reforms.

So for her to have lived through that, she didn’t come to North America until she was 23 or 24, so that was her life. As a young girl, she was on the junior national Ski team for Czechoslovakia. My grandfather used to train her. They used to put the skis on her back and walk up the mountain in Czechoslovakia because there were no ski lifts. She actually made me do that when I was a child just to let me know what her experience had been. If I complained that it was cold out, she’s like, “Well, you didn’t have to walk up the mountain. You’d be plenty warm if you had carried the skis up on your back, up the last run.”
Lex Fridman
I feel like they made people tougher back then, like my grandma. And you mentioned, it’s funny, they go through some of the darkest things that a human being can go through and they don’t talk about it, and they have a general positive outlook on life that’s deeply rooted in the knowledge of what life could be. How bad it could get. My grandma survived Holodomor in Ukraine, which was a mass starvation brought on by the collectivist policies of the Stalin regime, and then she survived the Nazi occupation of Ukraine. Never talked about it. Probably went through extremely dark, extremely difficult times, and then just always had a positive outlook on life. And also made me do very difficult physical activity, as you mentioned, just to humble you. Kids these days are soft kind of energy, which I’m deeply, deeply grateful for on all fronts, including just having hardship and including just physical hardship flung at me. I think that’s really important.

You wonder how much of who they were was a reaction to their experience. Would she have naturally had that forward-looking, grateful, optimistic orientation or was it a reaction to her childhood? I think about that. I look at this picture of my mom and she was unabashedly herself. She loved flamboyance and glamour, and in some ways I think it probably was a direct reaction to this very austere, controlled childhood. This was one expression of it. I think how she dressed and how she presented, I think her entrepreneurial spirit and love of capitalism and all things American was another manifestation of it and one that I grew up with. I remember the story she used to tell me about when she was 14 and she was going to neighboring countries, and as an athlete, you were given additional freedoms that you wouldn’t otherwise be afforded in these societies under communist rule.

So she was able to travel, where most of her friends never would be able to leave Czechoslovakia, and she would come back from all of these trips where she’d do ski races in Austria and elsewhere, and the first thing she had to do was check in at the local police. And she’d sit down, and she had enough wisdom at 14 to know that she couldn’t appear to be lying by not being impressed by what she saw and the fact that you could get an orange in the winter, but she couldn’t be too excited by it that she’d become a flight risk.
Lex Fridman
Oh, boy.
Oh, boy.
Ivanka Trump
So give enough details that you are believable, but not so many that you’re not trusted. And imagine that as a 14-year-old, that experience and having to navigate the world that way. And she told me that eventually all those local police officers, they came to love her because one of the things she’d do is smuggle stuff back from these countries and give it to them to give their wives perfume and stockings. So she figured out the system pretty quickly, but it’s a very different experience from what I was navigating and the pressures and challenges me as a 14-year-old was dealing with, so I have so much respect and admiration for her.

Yeah, hardship clarifies what’s important in life. You and I have talked about Man’s Search for Meaning, that book. Having an ultimate hardship clarifies that finding joy in life is not about the environment, it’s about your outlook on that environment. And there’s beauty to be found in any situation. And also, in that particular situation, when everything is taken from you, the thing you start to think about is the people you love. So in the case of Man’s Search for Meaning, Viktor Frankl thinking about his wife and how much he loves her, and that love was the flame, the warmth that kept him excited. The fun thing to think about when everything else is gone. So we sometimes forget that with the busyness of life, you get all this fun stuff we’re talking about like building and being a creative force in the world. At the end of the day, what matters is just the other humans in your life, the people you love.

Viktor Frankl, that book and just his philosophy in general is so inspiring to me. But I think so many people, they say they want happiness, but they want conditional happiness. When this and this a thing happens or under these circumstances, then I’ll be happy. And I think what he showed is that we can cultivate these virtues within ourselves regardless of the situation we find ourselves in. And in some ways, I think the meaning of life is the search for meaning in life. It’s the relationships we have and we form. It’s the experience we have. It’s how we deal with the suffering that life inevitably presents to us. And Viktor Frankl does an amazing job highlighting that under the most horrific circumstances, and I think it’s just super inspiring to me.

He also shows that you can get so much from just small joys, like getting a little more soup today than you did yesterday. It’s the little stuff. If you allow yourself to love the little stuff of life, it’s all around you. It’s all there. So you don’t need to have these ambitious goals and the comparison being a thief of joy, that kind of stuff. It’s all around us. The ability to eat. When I was in the jungle and I got severely dehydrated, because there’s no water, you run out of water real quick. And the joy I felt when I got to drink. I didn’t care about anything else. Speaking of things that matter in life, I would start to fantasize about water, and that was bringing me joy.

Oh, for sure. For sure. It’s good to have stuff taken away for a time. That’s why struggle is good, to make you appreciate it. To have a deep gratitude for when you have it. And water and food is a big one, but water is the biggest one. I wouldn’t recommend it necessarily, to get severely dehydrated to appreciate water, but maybe every time you take a sip of water, you can have that kind of gratitude.

There’s a prayer in Judaism you’re supposed to say every morning, which is basically thanking God for your body working. It’s something so basic, but it’s when it doesn’t that we’re grateful. So just reminding ourselves every day the basic things of a functional body, of our health, of access to water, which so many millions of people around the world do not have reliably, is very clarifying and super important.

Ivanka Trump
I have these vignettes in my mind, seeing her in action in different capacities, a lot of times in the context of things that I would later go on to do myself. So I would go almost every day after school, and I’d go to the Plaza Hotel and I’d follow her around as she’d walk the hallways and just observe her. And she was so impossibly glamorous. She was doing everything in four-and-a-half-inch heels, with this bouffant. It’s almost an inaccessible visual. But I think for me, when I saw her experience the most joy tended to be by the sea, almost always. Not a pool. And I think I get this from her. Pools, they’re fine. I love the ocean. I love saltwater. I love the way it makes me feel, and I think I got that from her. So we would just swim together all the time. And it’s a lot of what I love about Miami actually, being so close to the ocean. I find it to be super cathartic. But a lot of my memories of my mom, seeing her really just in her bliss, is floating around in a body of saltwater.

Is there also some aspect to her being an example of somebody that could be beautiful and feminine, but at the same time powerful, a successful businesswoman, that showed that it’s possible to do that?

Yeah, I think she really was a trailblazer. It’s not uncommon in real estate for there to be multiple generations of people. And so on job sites, it was not unusual for me to run into somebody whose grandfather had worked with my grandfather in Brooklyn or Queens or whose father had worked with my mother. And they’d always tell me these stories about her rolling in and they’d hear the heels first. And a lot of times, the story would be like, “Oh gosh, really? It’s two days after Christmas. We thought we’d get a reprieve.” But she was very exacting. So I had this visual in my mind of her walking on rebar on the balls of her feet in these four-inch heels. I’m assuming she actually carried flats with her, but I don’t know. That’s not the visual I have.

I loved the fact that she so embodied femininity and glamour and was so comfortable being tough and ambitious and determined and this unbelievable businesswoman and entrepreneur at a time when she was very much alone, even for me in the development world. And so many of the different businesses that I’ve been in, there really aren’t women outside of sales and of marketing. You don’t see as many women in the development space, in the construction space, even in the architecture and design space, maybe outside of interior design. And she was decades ahead of me, so I love hearing these stories. I love hearing somebody who’s my peer tell me about their grandfather and their father and their experience with one of my parents. It’s amazing.

That would be your exact thing. And when I’d complain about wearing something, and it was the early nineties. Everything was all so uncomfortable, these fabrics and materials, and I would go back and forth between being super girly and a total tomboy. But she’d dress me up in these things and I’d be complaining about it and she’d say, “Ivanka, pain for beauty,” which I happen to totally disagree with because I think there’s nothing worse than being uncomfortable. So I haven’t accepted or internalized all of this wisdom, so to speak, but it was just funny. She had a very specific point of view.

It’s funny because just even in fashion, if something’s uncomfortable, to me, there’s nothing that looks worse than when you see somebody tottering around and their heels hurt them, so they’re walking oddly, and they’re not embodying their confidence in that regard. So I’m the opposite. I start with, “Well, I want to be comfortable,” and that helps me be confident and in command.

And she was never doing those things either, so I don’t know how she was wearing stuff like that. That’s a 40-pound beaded dress, and I know this because I have it and I wore it recently. And I got a work out walking to the elevator. This is a heavy dress. And you know what? It was worth it. It was great.

She’s 97, and until she was around 94, she lived completely on her own. No help, no anything, no support. Now she requires really 24-hour care, and I feel super grateful that I’m able to give her that because that’s what she did for me. It’s amazing for me to have my children be able to grow up and know her stories, know her recipes, Czech dumplings and goulash and [foreign language 00:50:28] and all the other things she used to make me in my childhood. But she was a major force in my life. My mom was working, so my grandmother was the person who was always home every day when I came back from school.

And I remember I used to shower and it would almost be comical. I feel like in my memory, and there was no washing machine I’ve seen on the planet that can actually do this, but in my memory, I’d go to shower and I dropped something on the bed and I’d come back into the room after my shower and it was folded, pressed. It was all my grandmother. She was running after me, taking care of me, and so it’s nice to be able to do that for her.
Lex Fridman
Yeah.
Yeah.

I got from her reading, my grandmother. She devoured books. Devoured books. She loved the more sensational ones. So some of these romance novels, I would pick them up, the covers, but she could look at any royal lineage across Europe and tell you all the mistresses.

All the drama. She loved it. But her face was always buried in a book. My grandfather, he was the athlete. He swam professionally or on the national team for Czechoslovakia, and he helped train my mom, as I was saying before, in skiing. So he was a great athlete and she was at home and she would read and cook, and so that’s something I remember a lot from my childhood. And she would always say, “I got reading from her.”

Speaking of drama, I had my English teacher in high school recommended a book for me by D.H. Lawrence. It’s supposed to be a classic. She’s like, “This is a classic you should read.” It’s called Lady Chatterly’s Lover. And I’ve read a lot of classics, but that one is straight-up a romance novel about a wife who is cheating with a gardener. And I remember reading this. In retrospect, I understand why it’s a classic because it was so scandalous to talk about sex in a book a hundred years ago or whatever.

Probably Sinatra and all that?

Ivanka Trump
Love Sinatra, loves Elvis, a lot of the greats. So I think I got a little bit of my love for music from him, but my mom shared that as well. One of the things in looking back that I think I inherited from my father as well is this interest or understanding of the importance of asking questions, and specifically questions of the right people, and I saw this a lot on job sites. I remember with the old post office building, there was this massive glass-topped atrium, so heating and cooling the structure was a Herculean lift. We had the mechanical engineers provide their thoughts on how we could do it efficiently, and so that the temperature never varied, and it was enormously expensive as an undertaking. I remember one of his first times on the site, because he had really empowered me with this project, and he trusted me to execute and to also rope him in when I needed it.

I remember one of his first times on the site, because he had really empowered me with this project, and he trusted me to execute and to also rope him in when I needed it.
But one of the first time he visits, we’re walking the hallway and we’re talking about how expensive this cooling system would be and heating system would be. And he starts stopping and he’s asking duct workers as we walk what they think of the system that the mechanical engineers designed. First few, fine, not great answers. The third guy goes, “Sir, if you want me to be honest with you, it’s obscenely over-designed. In the circumstance of a 1000-year storm, you will have the exact perfect temperature, if there’s a massive blizzard or if it’s unbearably hot, but 99.9% of the time you’ll never need it. And so I think it’s just an enormous waste of money.” And so he kept asking that guy questions, and we ended up overhauling the design pretty well into the process of the whole system, saving a lot of money, creating a great system that’s super functional.
And so I learned a lot, and that’s just one example of countless. That one really sticks out of in my head because I’m like, “Oh my gosh, we’re redesigning the whole system.” We were actively under construction. But I would see him do that on a lot of different issues. He would ask people on the work level what their thoughts were. Ideas, concepts, designs. And there was almost like a Socratic first principles type of way he questioned people, trying to get down to trying to reduce complex things to something really fundamental and simple. So I try to do that myself to the best I can, and I think it’s something I very much learned from him.
Lex Fridman
Yeah, I’ve seen great engineers, great leaders do just that. You see, you want to do that a lot, which is basically ask questions to push simplification. Can we do this simpler? The basic question is, “Why are we doing it this way? Can this be done simpler?” And not taking as an answer that this is how we’ve always done it. It doesn’t matter that’s how we’ve always done it. What is the right way to do it? And usually, the simpler it is, the more correct the way. It has to do with costs, has to do with simplicity of production, manufacture, but usually simple is best.

And it’s oftentimes not the architecture or the engineers. It’s in Elon’s case probably the line worker who sees things more clearly. So I think making sure it’s not just that you’re asking good questions, you’re asking the right people those same good questions.

That’s why a lot of the Elon companies are really flat in terms of organizational design, where anybody on the factory floor can talk directly to Elon. There’s not this managerial class, this hierarchy, where [inaudible 00:58:16] have to travel up and down the hierarchy, which large companies often construct this hierarchy of managers where no one manager, if you ask them the question of what have you done this week, the answer is really hard to come up with. Usually, it’s going to be a bunch of paperwork, so nobody knows what they’re actually do. So when it’s flat, you can actually get as quickly as possible with when problems arise, you can solve those problems as quickly as possible. And also, you have a direct, rapid, iterative process where you’re making things simpler, making them more efficient, and constantly improving.

Yeah. It’s interesting. You see this in government. A lot of people get together, a hierarchy is developed, and sometimes it’s good, but very often just slows things down. And you see great companies, great, great companies, Apple, Google, Meta, they have to fight against that bureaucracy that builds, the slowness that large organizations have. And to still be a big organization and act like a startup is the big challenge.
Ivanka Trump
It’s super difficult to deconstruct that as well once it’s in place. It’s circumventing layers and asking questions, probing questions, of people on the ground level is a huge challenge to the authority of the hierarchy. And there’s tremendous amount of resistance to it. So it’s how do you grow something, in the case of a company, in terms of a culture that can scale but doesn’t lose its connection to real and meaningful feedback? It’s not easy.

I’ve had a lot of conversations with Jim Keller, who’s this legendary engineer and leader, and he has talked about you often have to be a little bit of an asshole in the room. Not in a mean way, but it is uncomfortable. A lot of these questions, they’re uncomfortable. They break the general politeness and civility that people have in communication. When you get a meeting, nobody wants to be like, “Can we do it way different?” Everyone wants to just like, “This lunch is coming up, I have this trip planned on the weekend with the family.” Everyone just wants comfort. When humans get together, they gravitate towards comfort. Nobody wants that one person that comes in and says, “Hey, can we do this way better and way different, and everything we’ve gotten comfortable with, throw it out?”

Not only do they not want that, but the one person who comes in and does that puts a massive target on their back and is ultimately seen as a threat. Nobody really gets fired for maintaining the status quo, even if things go poorly. It’s the way it was always done.

… kind of mood you were in, but this sort of second body, if you will. So I loved fashion and look, I mean my mother was a big part of the reason I did, but I never thought I would go into fashion. In fact, I was graduating from Warden, it was the day of my graduation and Winter calls me up and offered me a job at Vogue, which is a dream in so many ways, but I was so focused. I wanted to go into real estate and I wanted to build buildings, and I told her that. So I really thought that that was going to be the path I was taking and then very organically fashion, it was part of my life, but it came into my life in a more professional capacity by talking with my first of many different partners that I had in the fashion space about…

So I really thought that that was going to be the path I was taking and then very organically fashion, it was part of my life, but it came into my life in a more professional capacity by talking with my first of many different partners that I had in the fashion space about…
He actually had showed me a building to buy. His family had some real estate holdings and I passed on the real estate deal. But we forged a friendship and we started talking about how in the space that he was in, fine jewelry, there was this lack of product and brands that were positioned for self-purchasing females. So everything was about the man buying the Christmas gift, the man buying the engagement ring. The stores felt like that they were all tailored towards the male aesthetic. The marketing felt like that. And what about the woman who had a salary and was really excited to buy herself a great pair of earrings or had just received a great bonus and was going to use it to treat herself? So we thought there was a void in the marketplace, and that was the first category. I launched Ivanka Trump Fine Jewelry, and we just caught lightning in a bottle.
It was really quickly after that I met my partner who had founded Nine West Shoes, really capable partner, and we launched a shoe collection which took off and did enormously well and then a clothing collection and handbags and sunglasses and fragrance. So we caught a moment and we found a positioning for the self-purchasing multidimensional woman. And we made dressing for work aspirational. At the time, we launched if you wanted to buy something for an office context, the brands that existed were the opposite of exciting. Nobody was taking pictures of what they were wearing to work and posting it online with some of these classic legacy brands. Really, it felt very much like it was designed by a team of men for what a woman would want to wear to the office. So we started creating this clothing that was feminine, that was beautiful, that was versatile, that would take a woman from the boardroom to an after-school soccer game to a date night with a boyfriend, to a walk in the park with their husband.
All the different ways women live their lives and creating a wardrobe for that woman who works at every aspect of their life, not just sort of the siloed professional part. And it was really compelling. We started creating great brand content and we had incredible contributors like Adam Grant who was blogging for us at the time and creating aspirational content for working women. It was actually kind of a funny story, but I now had probably close to 11 different product categories and we were growing like wildfire and I started to think about what would be a compelling way to create interesting content for the people who were buying these different categories. And we came up with a website called Women Who Work, and I went to a marketing agency, one of the fancy firms in New York, and I said, “We want to create a brand campaign around this multidimensional woman who works and what do you think? Can you help us?” And they come back and they say, “You know what? We don’t like the word work. We think it should be women who do.”
And I just start laughing because I’m like women who do. And the fact that they couldn’t conceive of it being sort of exciting and aspirational and interesting to sort of lean into working at all aspects of our lives was just fascinating to me, but showed that that was part of the problem. And I think that’s why ultimately, I mean when the business grew to be hundreds of millions of dollars in sales, we were distributed at all the best retailers across the country from Neiman Marcus, to Saks to Bloomingdale’s and beyond. And I think it really resonated with people in an amazing way and probably not dissimilar to how I have this incredible experience every time somebody comes up to me and tells me that they were married in a space that I had painstakingly designed, I have that experience now with my fashion company. The number of women who will come up tell me that they loved my shoes or they loved the handbags, and I’ve had women show me their engagement rings. They got engaged with us and it’s really rewarding. It’s really beautiful.

I feel like the product… I think first and foremost, you have to have the right partner. So building a shoe, if you talk to a great shoe designer, it’s like it’s architecture. Making a heel that’s four inches that feels good to walk in for eight hours a day, that is an engineering feat. And so I found great partners in everything that I did. My shoe partner had founded Nine West, so he really knew what went into making a shoe wearable and comfortable. And then you overlay that with great design and we also created this really comfortable, beautifully designed, super feminine product offering that was also affordably priced. So I think it was the trifecta of those three things that I think it made it stand out for so many people.

So not being a designer, and this was true in real estate as well, I was never the architect, so I didn’t necessarily have the pen. And in fashion, the same way. I was kind of like a conductor. I knew what I liked and didn’t like, and I think that’s really important and that became honed for me over time. So I would have to sit a lot longer with something earlier on than later when I had more refined my aesthetic point of view. And so I think first of all, you have to have a pretty strong sense of what resonates with you. And then in the case of my fashion business, as it grew and became quite a large business and I had so many different categories, everything had to work together. So I had individual partners for each category, but if we were selling at Neiman Marcus, we couldn’t have a pair of shoes that didn’t relate to a dress, that didn’t relate to a pair of sunglasses and handbags all on the same floor.

So in the beginning, it was much more collaborative. As time passed, I really sort of took the point on deciding, this is the aesthetic for the season, these are the colors we’re going to use, these are fabrics, and then working with our partners on the execution of that. But I needed to create an overlay that allowed for cohesion as the collection grew. And that was actually really fun for me because that was a little different. I was typically initially responding to things that were put in front of me, and towards the end it was my partners who were responding to the things that myself and my team… But I always wanted to bring the best talent in. So I was hiring great designers and printmakers and copywriters. And so I had this almost like… That conductor analogy. I had this incredible group of, in this case, women assembled who had very strong points of view themselves and it created a great team.

So yeah, I mean, great team is really sort of essential. It’s the essential thing behind any successful story.

But there’s this thing of taste, which is really interesting because it’s hard to articulate what it takes, but basically knowing A versus B what looks good. Or without A-B comparison to say, “If we changed this part, that would make it better.” That sort of designer taste, that’s hard to make explicit what that is, but the great designers have that taste, like, “This is going to look good.” And it’s not actually… Again, the Steve Jobs thing, it’s not the opinion poll. You can’t poll people and ask them what looks better. You have to have the vision of that. And as you said, you also have to develop eventually the confidence that your taste is good, such that you can curate, you can direct teams. You can argue that no, no, no, this is right. Even when there’s several people that say, “This doesn’t make any sense.” If you have that vision, have the confidence, this will look good. That’s how you come up with great designs. It’s a mixture of great tastes as do develop over time and the confidence.

But to have a point of view and to challenge people who are such artists respectfully, but not to be afraid to ask questions, it takes a lot of confidence to do that. And it’s hard.

Amman’s going to operate the hotel for us, and they’re going to be villas, and we have Carbone who’s going to be doing the food and beverage. But it’s amazing to bring together all of this talent. And for me to be able to play around and flex the real estate muscles again and have some fun with it is-

The real estate, the design, the art. How hard is it to bring something like that to life because that looks surreal, out of this world?

Well, especially on an island, it’s challenging, meaning the logistics of even getting the building materials to an island are no joke, but we will execute on it. And it may not be this. This is sort of, as I said, early conceptual drawings, but it gives a sense of wanting to honor the topography that exists. And this is obviously very modern, but making it feel right in terms of the context of the vegetation and the terrain that exists is, and not just have a beautiful glass box. Obviously you want glass. You want to look out and see that gorgeous blue ocean, but how do you do that in a way that doesn’t feel generic and isn’t a squandered opportunity to create something new?

Yeah. And it’s integrated with a natural landscape. It’s a celebration of the natural landscape around it. So I guess you start from this dream-like… Because this feels like a dream. And then when you’re faced with the reality of the building materials and all the actual constraints of the building, then it evolves from there, right?

Ivanka Trump
Yeah. And I mean so much of architecture you don’t see, but it’s decisions made. So how do you create independent structures where you look out of one and don’t see the other? How do you ensure the stacking and the master plan works in a way that’s harmonious and view corridors? And all of those elements, all of those components of decision-making are super appreciated, but not often thought about.

What’s a view corridor?
What’s a view corridor?
Ivanka Trump
To make sure that the top unit, you’re not looking out and seeing a whole bunch of units, you’re looking out and seeing the ocean. So that’s where you take this and then you start angling everything and you start thinking about, “Well, in this context, do we have green roofs?” If there’s any hint of a roof, it’s camouflaged by vegetation that matches what already exists on the island. That’s where the engineers become very important. How do you build into a mountainside while being sensitive to the beauty of the island?

It’s almost like a mathematical problem. I took a class, computational geometry in grad school, where you have to think about these view corridors. It’s like a math problem, but it’s also an art problem because it’s not just about making sure that there’s no occlusions to the view. You have to figure out when there is occlusions, what is a vegetation. So you have to figure all that out. And there’s probably… So every single room, every single building is a thing that adds extra complexity.

And then the choices, how does the sun rise and set? So how do you want to angle the hotel in relation to the sunrise and the sunset? You obviously want people to experience those. So which do you favor the directionality of the wind and on an island, and in this case, the wind’s coming from the north and the vegetation is less lush on the northern end. So do you focus more on the southern end and have the horseback riding trails and amenities up towards the north? So there are these really interesting decisions and choices you get to reflect on.

Well, the grade of the land, if it’s super steep. So also finding the areas of topography that are flatter but still have the great views. So it’s fun. I think real estate and building, it’s like a giant puzzle. And I love puzzles. Every piece relates to another, and it’s all sort of interconnected.

You can tell if it’s by accident or if it’s intentional. You can tell. So much… I mean, the whole hospitality thing. It’s not just how it’s designed. It’s how once the thing is operating, if it’s a hotel, how everything comes together, the culture of the place.

And the warmth. I think with spaces, you can feel the soul of a structure. And I think on the hotel side, you have to think about flow of traffic, use, all these things. When you’re building condominiums or your own home, you want to think about the warmth of a space as well. And especially with super modern designs, sometimes warmth is sacrificed. And I think there is a way to sort of marry both, and that’s where you get into the interior design elements and disciplines and how fabrics can create tremendous warmth in a space which is otherwise sort of colder, raw building materials. And that’s a really interesting… How texture matters, how color matters. And I think oftentimes interior design is not… It doesn’t take the same priority. And I think that underestimates the impact it can have on how you experience a room or space.

This is basically an Ikea… This is not deeply thought through, but it does bring me joy. Which is one way to do design. As long as you’re happy, if your taste is decent enough, that means others will be happy or will see the joy radiate through it. But I appreciate you were grasping for compliments and you eventually got there.

Yeah, there’s robot… I don’t know how much you’ve looked into robots, but there’s a way to communicate love and affection from a robot that I’m really fascinated by. And a lot of cartoonists do this too. When you create cartoons and non-human-like entities, you have to bring out the joy. So with Wall-E or robots in Star Wars, to be able to communicate emotion, anger and excitement through a robot is really interesting to me. And people that do it successfully are awesome.

I think there’s so many detailed elements that I think artists know well, but one basic one is something that people know and you now know because you have a dog is the excitement that a dog has when you first show up. Just the recognizing you and catching your eye and just showing his excitement by wiggling his butt and tail and all this intense joy that overtakes his body, that moment of recognizing something. It’s the double take, that moment of where this joy of recognition takes over your whole cognition and you’re just there and there’s a connection. And then the other person gets excited and you both get excited together. It’s kind of like that feeling… How would I put it? When you go to airports and you get to see people who haven’t seen each other for a time all of a sudden recognize each other in their meeting and they’re all run towards each other in a hug? That moment. By the way, that’s awesome to watch. There’s so much joy.

And dogs though will have that, every time. You could walk into the other room to get a glass of milk and you come back and your dog sees you like it’s the first time. So I love replicating that in robots. They actually say children… One of the reasons why Peek-A-Boo is so successful is that they actually don’t remember not having seen you a few seconds prior. There’s a term for it, but I remember when my kids were younger, you leave the room and you walk back in 30 seconds later and they experienced the same joy as if you had been gone for four hours. And we grow out of that. We become very used to one another.

Self-doubt
Lex Fridman
I kind of want to forever be excited by the Peek-A-Boo phenomena, the simple joys. We’re talking about on fashion, having the confidence of taste to be able to sort of push through on this idea of a design. But you’ve also mentioned somebody you admire is Rick Rubin in his book, The Creative Act. It has some really interesting ideas, and one of them is to accept self-doubt and imperfection. So is there some battle within yourself that you have on sort of striving for perfection and for the confidence and always kind of having it together versus accepting that things are always going to be imperfect?

I think every day. I think I wake up in the morning and I want to be better. I want to be a better mom. I want to be a better wife. I want to be more creative. I want to be physically stronger. And so that very much lives within me all the time. I think I also grew up in the context of being the child of two extraordinarily successful parents, and that could have been debilitating for me. And I saw that in a lot of my friends who grew up in circumstances similar to that. They were afraid to try for fear of not measuring up.

And I saw that in a lot of my friends who grew up in circumstances similar to that. They were afraid to try for fear of not measuring up.
And I think somehow early on I learned to kind of harness the fear of not being good enough, not being competent enough, and I harnessed it to make me better and to push me outside of my comfort zone. So I think that’s always lived with me, and I think it probably always will. I think you have to have humility in anything you do that you could be better and strive for that. I think as you get older, it softens a little bit as you have more reps, as you have more examples of having been thrown in the deep end and figured out how to swim. You get a little bit more comfortable in your abstract competency. But if that fear is not in you, I think you’re not challenging yourself enough.
Intuition
Lex Fridman
Harness the fear. The other thing he writes about is intuition, that you need to trust your instincts and intuition. That’s a very recruitment thing to say. So what percent of your decision making is intuition or what percent is through rigorous careful analysis, would you say?

Ivanka Trump
I think it’s both. It’s like trust, but verify. I think that’s also where age and experience comes into play, because I think you always have sort of a gut instinct, but I think well-honed intuition comes from a place of accumulated knowledge. So oftentimes when you feel really strongly about something, it’s because you’ve been there, you know what’s right. Or on a personal level, if you’re acting in accordance with your core values, it just feels good. And even if it would be the right decision for others, if you’re acting outside of your integrity or core values, it doesn’t feel good and your intuition will signal that to you. You’ll never be comfortable. So I think because of that, I start oftentimes with my intuition and then I put it through a rigorous test of whether that is in fact true. But very seldom do I go against what my initial instinct was, at least at this point in my life.

Yeah, I had actually a discussion yesterday with a big time business owner investor who’s talking about being impulsive and following that on a phone call, shifting the entire everything… Giving away a very large amount of money and moving it in another direction on an impulse. Making a promise that he can’t at that time deliver, but knows if he works hard, he’ll deliver and all… Just following that impulsive feeling. And he said now that he has a family, that probably some of that impulse is quieted down a little bit. He’s more rational and thoughtful and so on, but wonders whether it’s sometimes good to just be impulsive and to just trust your gut and just go with it. Don’t deliberate too long because then you won’t do it. It’s interesting. It’s the confidence and stupidity maybe of youth that leads to some the greatest breakthroughs, and there’s a cost to wisdom and deliberation.

There is. But I actually think in this case, as you get older, you may act less impulsively, but I think you’re more like attuned with… You have more experience, so your gut is more well honed. So your instincts are more well honed. I think I found that to be true for me. It doesn’t feel as reckless as when I was younger.

Going to go with that. She was amazing. But it was such a wild experience for me because I was quite young when I was on it just getting started in business, and it was the number one television show in the country, and it went on to be syndicated all over the world, and it was just this wild, phenomenal success. A business show had never crossed over in this sort of way. So it was really a moment in time and you had regular Apprentice and then the Celebrity Apprentice. But the tasks, I mean, they went on to be studied at business schools across the country. So every other week, I’d be reading case studies of how The Apprentice was being examined and taught to classes and this university in Boston. So it was extraordinary. And this was a real life classroom I was in. So I think because of the nature of the show, you learn a lot about teamwork and you’re watching it and analyzing it real time.

A lot of the tasks were very marketing oriented because of the short duration of time they had to execute. You learned a lot about time management because of that short duration. So almost every episode would devolve into people hysterical over the fact that they had 10 minutes left with this Herculean lift ahead of them. So it was a fascinating experience for me. And we would be filming… I mean, we would film first thing in the morning at 5 or 6 AM in Trump Tower, oftentimes. In the lobby of Trump Tower, that’s where the war rooms and boardrooms of the candidates were, the contestants were. And then we would go up in the elevator to our office. We would work all day, and then we’d come down and we’d evaluate the task. It was this weird real life television thing experience in the middle of our… Sort of on the bookends of our work day. So it was intense.
Lex Fridman

There were episodes that they came up with brand campaigns for my shoe collection or my clothing line or design challenges related to a hotel I was responsible for building. So there was this unbelievable crossover that was obviously great for us from a business perspective, but it’s sometimes surreal to experience.

Michael Jackson
Lex Fridman
I think certain people are just born to be entertainers. Like Elvis on stage, they come to life. This is where they’re truly happy. I’ve met guys like that. Great rock stars. This is where they feel like they belong, on stages. It’s not just a thing they do and there’s certain aspects they love, certain aspects they don’t. This is where they’re alive. This is where they’ve always dreamed of being. This is where they want to be forever.

And I was working really hard. I was going to the School of American Ballet. I was dancing at the Lincoln Center in the Nutcracker. I was super serious, nine, 10-year-old. And my parents came to a Christmas performance of the Nutcracker and my father brought Michael Jackson with him. And everyone was so excited that all the dancers, they wore one glove. But I remember he was so shy. He was so quiet when you’d see him in smaller group settings. And then you’d watch him walk onto to stage and it was like a completely different person, like the vitality that came into him. And you say that’s like someone who was born to do what he did. And I think there are a lot of performers like that.

Nature
Lex Fridman
And I just in general love to see people that have found the thing that makes them come alive. I, as I mentioned, went to the jungle recently with Paul Rosolie, and he’s a guy who just belongs in the jungle. That’s a guy where when I got a chance to go with him from the city to the jungle, and you just see this person change, of the happiness, the joy he has when he first is able to jump in the water of Amazon River and to feel like he’s home with the crocodiles, and all that, with his calling friends and probably dances around in the trees with the monkeys. So this is where he belongs, and I love seeing that.

You felt that. I mean, I watched the interview you did with him and he felt that his passion and enthusiasm, it radiated. And I mean, I love animals. I love all animals. Never loved snakes so much. And he almost made me, now I appreciate the beauty of them much more than I did prior to listening to him speak about them. But it’s an infectious thing. He actually, we were talking about skyscrapers before. I loved it. He called trees skyscrapers of life, and I thought that was so great.

Yeah, and they are. They’re so big. Just like skyscrapers or large buildings, they also represent a history, especially in Europe. I like to think, looking at all these ancient buildings, you like to think of all the people throughout history that have looked at them, have admired them, have been inspired by them. The great leaders of history. In France it’s like Napoleon, just the history that’s contained within a building, you almost feel the energy of that history. You can feel the stories emanate from the buildings. And that same way when you look at giant trees that have been there for decades, for centuries in some cases, you feel the history, the stories emanate. I got a chance to climb some of them, so you feel like there’s a visceral feeling of the power of the trees. It’s cool.

Being in the jungle among the trees, among the animals, you remember that you’re forever a part of nature. You’re fundamentally our nature, Earth is a living organism and you’re a part of that organism. And that’s humbling, that’s beautiful, and you get to experience that in a real, real way. It sounds simple to say, but when you actually experience it stays with you for a long time. Especially if you’re out there alone. I got a chance to spend time in the jungle solo, just by myself. And you sit in the fear of that, in the simplicity of that, all of it, and just no sounds of humans anywhere. You’re just sitting there and listening to all the monkeys and the birds trying to have sex with each other, all around you just screaming. And I mean, I romanticize everything, there’s birds that are monogamous for life, like macaws, you could see two of them flying. They’re also, by the way, screaming at each other. I always wonder, “Are they arguing or is this their love language?”

I think it’s so humbling to feel so small too. I feel like when we get busy and when we’re running around, it’s easy to feel we’re so in our head and we feel sort of so consequential in the context of even our own lives. And then you find yourself in a situation like that, and I think you feel so much more connected knowing how minuscule you are in the broader sense. And I feel that way when I’m on the ocean on a surfboard. It’s really humbling to be so small amidst that vast sea. And it feels really beautiful with no noise, no chatter, no distractions, just being in the moment. And it sounds like you experienced that in a very, very real way in the Amazon.

Yeah, the power of the waves is cool. I love swimming out into the ocean and feeling the power of the ocean underneath you, and you’re just like this speck.

You just have to sort of be in it. And I think in surfing, one of the things I love about it is I feel like a lot of water sports you’re manipulating the environment. And there’s something that can be a little violent about it, like you look at windsurfing. Whereas with surfing, you’re in harmony with it. So you’re not fighting it, you’re flowing with it. And you still have the agency of choosing which waves you’re going to surf, and you sit there and you read the ocean and you learn to understand it, but you can’t control it.

What’s it like to fall in your face when you’re trying to surf? I haven’t surfed before. It just feels like I always see videos of when everything goes great. I just wonder when it doesn’t.

Those are the ones people post. No, well, I actually had the unique experience of one of my first times surfing. I only learned a couple of years ago, so I’m not good, I just love it. I love everything about it. I love the physicality, I love being in the ocean, I love everything about it. The hardest thing with surfing is paddling out, because when you’re committing, you catch a wave, obviously sometimes you flip over your board and that doesn’t feel great. But when you’re in the line of impact and you’ve maybe surfed a good wave in and now you’re going out for another set, and you get stuck in that impact line, there’s nothing you can do. You just sit there and you try to dive underneath it and it will pound you and pound you.

So, I’ve been stuck there while four or five, six waves just crash on top of your head. And the worst thing you can do is get reactive and scared, and try and fight against it. You just have to flow with it until inevitably there’s a break and then paddle like hell back out to the line, or to the beach, whatever you’re feeling. But to me that’s the hardest part, the paddling out.
Donald Trump

How did life change when your father decided to run for president?
How did life change when your father decided to run for president?
Ivanka Trump
Wow, everything changed almost overnight. We learned that he was planning to announce his candidacy two weeks before he actually did. And nothing about our lives had been constructed with politics in mind. Most often when people are exposed to politics at that level, that sort of national level, there’s first city council run, and then maybe a state-level run, and maybe, maybe congress, senator ultimately the presidency. So it was unheard of for him never to have run a campaign and then run for president and win. So it was an extraordinary experience. There was so much intensity and so much scrutiny and so much noise. So that took for sure a moment to acclimate to. I’m not sure I ever fully acclimated, but it definitely was a super unusual experience.

I’m not sure I ever fully acclimated, but it definitely was a super unusual experience.
But I think then the process that unfolded over the next couple of years was also the most extraordinary growth experience of my life. Suddenly, I was going into communities that I probably never would have been to, and I was talking with people who in 30 seconds would reveal to me their deepest insecurity, their gravest fear, their wildest ambitions, all of it, with the hope that in telling me that story, it would get back to a potential future President of the United States and have impacts for their family, for their community.
So, the level of candor and vulnerability people have with you is unlike anything I’ve ever experienced. And I had done The Apprentice before, people may know who I was in some of these situations that I was going into, but they wouldn’t have shared with me these things that you got the impression that oftentimes their own spouses wouldn’t know, and they wouldn’t do so within 30 seconds. So you learn so much about what motivates people, what drives people, what their concerns are, and you grow so much as a result of it.
Lex Fridman
So when you’re in the White House, people, unlike in any other position, people have a sense that all the troubles they’re going through, maybe you can help, so they put it all out there.

And they do so in such a raw, vulnerable, and real way. It’s shocking and eyeopening and super motivating. I remember once I was in New Hampshire, and early on, right after my father had announced his candidacy, and a man walks up to me in the greeting line and within around five seconds he had started to tell me a story about how his daughter had died of an overdose, and how he was worried his son was also addicted to opioids, his daughter’s friends, his son’s friends. And it’s heartbreaking. It’s heartbreaking, and it’s something that I would experience every day in talking with people.

I took a long road trip around the United States in my 20s, and I’m thinking of doing it again just for a couple of months for that exact purpose. And you can get these stories when you go to a bar in the middle of nowhere and just sit and talk to people and they start sharing. And it reminds you of how beautiful the country is. It reminds you of several things. One, that people, well, it shows you that there’s a lot of different accents, that’s for one. But aside from that, that people are struggling with all the same stuff.

But aside from that, that people are struggling with all the same stuff.
And at least at that time, I wonder what it is now, but at that time, I don’t remember. On the surface, there’s political divisions, there’s Republicans and Democrats, and so on, but underneath it people were all the same. The concerns were all the same, there was not that much of a division. Right now, the surface division has been amplified even more maybe because of social media, I don’t know why. So, I would love to see what the country’s like now. But I suspect probably it’s still not as divided as it appears to be on the surface, what the media shows, what the social media shows. But what did you experience in terms of the division?
Ivanka Trump
I think a couple reactions to what you just said. I think the first is when you connect with people like that, you are so inspired by their courage in the face of adversity and their resilience. And it’s a truly remarkable experience for me. The campaign lifted me out of a bubble I didn’t even know I was in. I grew up on the Upper East Side of New York and I felt like I was well traveled, and I believed at the time that I’d been exposed to divergent viewpoints. And I realized during the campaign how limited my exposure had been relative to what it was becoming, so there was a lot of growth in that as well.

But I do think you think about the vitriol and politics and whether it’s worse than it’s been in the past or not, I think that’s up for debate. I think there have been duels, there’s been screaming, and politics has always been a blood sport, and it’s always been incredibly vicious. I think in the toxic swirl of social media it’s more amplified, and there’s more democratization around participating in it perhaps, and it seems like the voices are louder, but it feels like it’s always been that. But I don’t believe most people are like that. And you meet people along the way and they’re not leading with what their politics are. They’re telling you about their hopes for themselves and their communities. And it makes you feel that we are a whole lot less divided than the media and others would have us believe.
Lex Fridman
Although, I have to say, having duals sounds pretty cool. Maybe I just romanticize westerns, but anyway. All right, I miss Clint Eastwood movies. Okay. But it’s true. You read some of this stuff in terms of what politics used to be in the history of the United States. Those folks went pretty rough, way rougher, actually. But they didn’t have social media, so they had to go real hard. And the media was rough too. So all the fake news, all of that, that’s not recent. It’s been nonstop.

I look at the surface division, the surface bickering, and that might be just a feature of democracy. It’s not a bug of democracy, it’s a feature. We’re in a constant conflict, and it’s the way we resolve, we try to figure out the right way forward. So in the moment, it feels like people are just tearing each other apart, but really we’re trying to find a way, where in the long arc of history it will look like progress. But in the short term, it just sounds like people making stories up about other and calling each other names, and all this kind of stuff, but there’s a purpose to it. I mean, that’s what freedom looks like, I guess is what I’m trying to say, and it’s better than the alternative.

What went into your decision to join the White House as an advisor?
What went into your decision to join the White House as an advisor?
Ivanka Trump
The campaign. I never thought about joining, it was like get to the end of it. And when it started, everything in my life was almost firing on all cylinders. I had two young kids at home. During the course of the campaign, I ended up, I was pregnant with my third, so this young family, my businesses, real estate and fashion, and working alongside my brothers running the Trump Hotel collection. My life was full and busy. And so, there was a big part of me that was just wanted to get through, just get through it, without really thinking forward to what the implications were for me.

My life was full and busy. And so, there was a big part of me that was just wanted to get through, just get through it, without really thinking forward to what the implications were for me.
But when my father won, he asked Jared and I to join him. And in asking that question, keep in mind he was just a total outsider, so there was no bench of people as he would have today. He had never spent the night in Washington DC before staying in the White House. And so, when he asked us to join him, he trusted us. He trusted in our ability to execute. And there wasn’t a part of me that could imagine the 70 or 80-year-old version of myself looking back and having been okay with having said no, and going back to my life as I knew it before. I mean, in retrospect, I realize there is no life as you know it before, but just the idea of not saying yes, wherever that would lead me. And so I dove in.
I was also, during the course of the campaign, I was just much more sensitive to the problems and experiences of Americans. I gave you an example before of the father in New Hampshire, but even just in my consumption of information. I had a business that was predominantly young women, many of which were thinking about having a kid, had just had a child, were planning on that life event. And I knew what they needed to be able to show up every day and realize this dream for themselves and the support structures they would need to have in place.
And I remember reading this article at the time in one of the major newspapers of a woman, she had had a very solid job working at one of the blue chip accounting firms. And the recession came, she lost her job around the same time as her partner left her. And over a matter of months, she lost her home. So, she wound up with her two young kids, after bouncing around between neighbors living in their car. She gets a callback from one of the many interviews she had done for a second interview where she was all but guaranteed the job should that go well, and she had arranged childcare for her two young children with a neighbor in her old apartment block.
And the morning of the interview, she shows up and the neighbor doesn’t answer the doorbell. And she stands there five, 10 minutes, doesn’t answer. So she has a choice: does she go to the interview with her children, or does she try to cancel? She gets in her car, drives to the interview, leaves her two children in the backseat of the car with the window cracked, goes into the interview and gets pulled out of the interview by police because somebody had called the cops after seeing her children in the backseat of the car. She gets thrown in jail, her kids get taken from her, and she spends years fighting to regain custody.
And I think about, that’s an extreme example, but I think about something like that. And I say, “If I was the mother and we were homeless, would I have gone to that interview?” And I probably would have, and that is not an acceptable situation. So you hear stories like that, and then you get asked, “Will you come with me?” And it’s really hard to say no. I spent four years in Washington. I feel like I left it all in the field. I feel really good about it, and I feel really privileged to have been able to do what I did.

… to get things done. There are a lot of people who would prefer to clinging to the problem and their talking points about how they’re going to solve it, rather than sort of roll up their sleeves and do the work it takes to build coalitions of support, and find people who are willing to compromise and move the ball. And so it’s extremely difficult. And Jared and I talk about it all the time, it probably should be, because these are highly consequential policies that impact people’s lives at scale. It shouldn’t be so easy to do them, and they are doable, but it’s challenging.

And it just meant meeting, after meeting, after meeting, after meeting with lawmakers, convincing them of why this is good policy, going into their districts, campaigning in their districts, helping them convince their constituents of why it’s important, of why childcare support is important, of why paid family leave is important, of different policies that impact working American families. So it’s hard, but it’s really rewarding.
And then to get it done, I mean, just the child tax credit alone, 40 million American families got an average of $2,200 each year as a result of the doubling of the child tax credits. That was one component of tax cuts.
Lex Fridman
When I was researching this stuff, you just get to think the scale of things. The scale of impact is 40 million families, each one of those is a story, is a story of struggle, of trying to give a large part of your life to a job while still being able to give love and support and care to a family, to kids, and to manage all of that. Each one of those is a little puzzle that they have to solve. And it’s a life and death puzzle. You can lose your home, your security, you can lose your job, you can screw stuff up with parenting, so you can mess all of that up and you’re trying to hold it together, and government policies can help make that easier, or can in some cases make that possible. And you get to do that a scale out of five or 10 families, but 40 million families. And that’s just one thing.

Yeah. The people who shared with me their experience, and during the campaign it was what they hoped to see happen. Once you were in there, it was what they were seeing, what they were experiencing, the result of the policies. And that was the fuel. On the hardest days, that was the fuel. Child tax credit.

Once you were in there, it was what they were seeing, what they were experiencing, the result of the policies. And that was the fuel. On the hardest days, that was the fuel. Child tax credit.
I remember visiting with a woman, Brittany Houseman, she came to the White House. She had two small children, she was pregnant with her third. Her husband was killed in a car accident. She was in school at the time. Her dream was to become criminal justice advocate. That was no longer on the table for her after he passed away and she became the sole earner and provider for her family. And she couldn’t afford childcare, she couldn’t afford to stay in school, so she ended up creating a child childcare center in her home.
And her center was so successful because in part of different policies we worked on, including the childcare block grants that went to the state. She ended up opening additional centers, I visited her at one of them in Colorado. Now she has a huge focus on helping teenage moms who don’t have the resources to afford quality childcare for their kids come into her centers and programs. And it’s stories like that of the hardships people face, but also what they do with opportunity when they’re given it, that really powers you through tough moments when you’re in Washington.
Lex Fridman
What can you say about the process of bringing that to life? So, the child tax credits, so doubling them from a $1,000, $2,000 per child, what are the challenges of that? Getting people to compromise? I’m sure there’s a lot of politicians playing games with that because maybe it’s a Republican that came up with an idea or a Democrat that came up with an idea, and so they don’t want to give credit to the idea. And there’s probably all kinds of games happening where when the game is happening, you probably forget about the families. Each politician thinks about how they can benefit themselves, if you get the serving part of the role you’re supposed to be in.

There were definitely people I met with in Washington who I felt that was true of. But they all go back to their districts and I assume that they all have similar experiences to what I had, where people share their stories. So there’d be something really cynical about thinking they forget, but some do.

Well, I think first and foremost, you have to be willing to talk with them. So, one of the policies I advocated for was paid family leave. We left, and nine million more Americans had it through a combination of securing it for our federal workforce. I had people in the White House who were pregnant who didn’t have access to paid leave. So, we want to keep people attached to the workforce, yet when they have an important life event like a child, we create an impossibility for that. Some people don’t even have access to unpaid leave if they’re part-time workers.

So, we want to keep people attached to the workforce, yet when they have an important life event like a child, we create an impossibility for that. Some people don’t even have access to unpaid leave if they’re part-time workers.
And so that, and then we also put in place the first ever national tax credit for workers making under $72,000 a year where employers could then offer it to their workers. That was also part of tax cuts. So part of it is really taking the arguments as to why this is good, smart, well-designed policy to people. And it was one of my big surprises that on certain policy issues that I thought would have been well socialized, the policies that existed were never shared across the aisle. So people just lived with them maybe in hopes that one day …
Ivanka Trump
… so people just lived with them maybe in hopes that one day they would have the votes to get exactly what they want. But I was surprised by how little discussion there was.
… so people just lived with them maybe in hopes that one day they would have the votes to get exactly what they want. But I was surprised by how little discussion there was.
So I think part of it is be willing to have those tough discussions with people who may not share your viewpoint and be an active listener when they point out flaws and they have suggestions for changes, not believing that you have a monopoly on good ideas. And I think there has to be a lot of humility in architecting these things. And a policy should benefit from that type of well-rounded input.
Lex Fridman
Yeah. Be able to see, like you said, well-designed policies. There’s probably the details are important too. Just like with architecture and you walk the rooms, there’s probably really good designs of policies, economic policy that helps families that delivers the maximum amount of money or resources to families that need it and is not a waste of money. So there’s probably really nice designs there and nice ideas that are bipartisan that has nothing to do with politics, has to do with just great economic policy, just great policies. And that requires listening.

I learned tax cuts was really interesting for me because I met with so many people across the political spectrum on advancing that policy. I really figured out who was willing to deviate from their talking points when the door was closed and who wasn’t. And it takes some courage to do that, especially without surety that it would actually get done, especially if they’ve campaigned on something that was slightly different. And not everyone has that courage. So through tax cuts, I learned the people who did have that courage and I went back to that, well time and time again on policies that I thought were important, some were bipartisan. The Great American Outdoors Act is something, it’s incredible policy.

Yeah, it’s amazing. It’s one of the largest pieces of conservation legislation since the National Park system was created. And over 300 million people visit our national parks, the vast majority of them being Americans every year. So this is something that is real and beneficial for people’s lives, getting rid of the deferred maintenance, permanently funding them. But there are other issues like that that just weren’t being prioritized.

Modernizing Perkins CTE in vocational education. And it’s something I became super passionate about and help lead the charge on. I think in America for a really long period of time, we’ve really believed that education stops when you leave high school or college. And that is not true and that’s a dangerous way to think. So how can we both galvanize the private sector to ensure that they continue to train workers for the jobs they know are coming and how they train their existing workforce into the new jobs with robotics or machinery or new technologies that are coming down the pike. So galvanizing the private sector to join us in that effort.
So whether it’s the legislative side, like the actual legislation of Perkins CTE, which was focused on vocational education or whether it’s the ability to use the White House to galvanize the private sector, we got over 16 million commitments from the private sector to retrain or re-skill workers into the jobs of tomorrow.
Lex Fridman
Yeah, there’s so many aspects of education that you helped on, access to STEM and computer science education. So the CTE thing, you’re mentioning modernizing career and technical education. And that’s millions, millions of people. The act provided nearly $1.3 billion annually to more than 13 million students to better align the employer needs and all that kind of stuff. Very large scale policies that help a lot of people. It’s fascinating.

Education often isn’t like the bright shiny object everyone’s running towards. So one of the hard things in politics, when there’s something that is good policy, sometimes it has no momentum because it doesn’t have a cheerleader. So where are areas of good policy that you can literally just carry across the finish line? Because people tend to run towards what’s the news of the day to try to address whatever issue is being talked about on the front pages of papers. And there’s so many issues that need to be addressed, and education is one of them that’s just under-prioritized.

Human trafficking. That’s an issue that I didn’t go to the White House thinking I would work on, but you hear a story of a survivor and you can’t not want to eradicate one of the greatest evils that the mind can even imagine. The trafficking of people, the exploitation of children. And I think for so many they assume that this is a problem that doesn’t happen on our shores. It’s something that you may experience at far-flung destinations across the world, but it’s happening there and it’s happening here as well.
And so through a coalition of people that on both sides of the aisle that I came to trust and to work well with, we were able to get legislation which the president signed, passed nine pieces of legislation, combating trafficking at home and abroad and digital exploitation of children.
Lex Fridman
How much of a toll does that take seeing all the problems in the world at such a large scale, the immensity of it all? Was that hard to walk around with that just knowing how much suffering there is in the world? As you’re trying to help all of it, as you’re trying to design government policies to help all of that, it’s also a very visceral recognition that there is suffering in the world. How difficult is that to walk around with?

Ivanka Trump
You feel it intensely. We were just talking about human trafficking. I mean you don’t design these policies in the absence of the input of survivors themselves. You hear their stories. I remember a woman who was really influential in my thinking, Andrea Hipwell who she was in college where she was lured out by a guy she thought was a good guy, started dating him. He gets her hooked on drugs, convinces her to drop out of college and spends the next five years selling her. She only got out when she was arrested. And all too often that’s happening too, that the victim’s being targeted, not the perpetrator.

So we did a lot with DOJ around changing that, but now she’s helping other survivors get skills and job training and the therapeutic interventions they need. But you speak with people like Andrea and so many others, and I mean you can’t not, your heart gets seized by it and it’s both, it’s motivating and it’s hard. It’s really hard.

I was just talking to a brain surgeon. Many of the surgeries he to do, he knows the chances are very low of success and he says that that wears his armor. It chips away. It’s like only so many times can you do that.

But you could see the pain in his eyes, maintaining your humanity while doing all of it. You could see the story, you could see the family that loves that person. You feel the immensity of that, and you feel the heartbreak involved with mortality in that case and with suffering also in that case, and in general in all these in human trafficking. But even helping families try to stay afloat, trying to break out or escape poverty, all of that, you get to see those stories of struggle. It’s not easy.

But the people that really feel the humanity of that, feel the pain of that are probably the right people to be politicians. But it’s probably also why you can’t stay in there too long.
Work-life balance
Ivanka Trump
It’s the only time in my life where you actually feel like there’s always a conflict, between work and life and making sure, as a woman, I’d often get asked about how do you balance work and family? And I never liked that question because balance, it’s elusive. You’re one fever away from no balance. Your child’s sick one day. What do you do? There goes balance. Or you have a huge project with a deadline. There goes balance.

Or you have a huge project with a deadline. There goes balance.
I think a better way to frame it is, am I living in accordance with my priorities? Maybe not every day, but every week, every month. And reflecting on have you architected a life that aligns with your priorities so that more often than not you’re where you need to be in that moment. And service at that level was the one time where you really you feel incredibly conflicted about having any priorities other than serving. It’s finite.
In every business I’ve built, you’re building for duration. And then you go into the White House and it is sand through an hourglass. Whether it’s four years or eight years, it’s a finite period of time you have. And most people don’t last four years. I think the average in the White House is 18 months. It’s exhausting. But it’s the only time when you’re at home with your own children that you feel, you think about all the people you’ve met and you feel guilty about any time that’s spent not advancing those interests to the best of your capacity.
And that’s a hard thing. That’s a really hard feeling as a parent. And it’s really challenging then to be present, to always need to answer your phone, to always need to be available. It’s very difficult, it’s taxing, but it’s also the greatest privilege in the world.

That was everything. To have that, to have the support systems I had in place with my husband and we had left New York and wound up in Washington. And New York, I lived 10 blocks away from my mother-in-law who if I wasn’t taking my kids to school, she was. So we lost some of that, which was very hard. But we had what mattered, which was each other. And my kids were young. When I got to Washington, Theo, my youngest was eight months old, and Arabella, my oldest, my daughter was five years old. So they were still quite young. We have a son, Joseph, who’s three. And I think for me, the dose of levity coming home at night and having them there and just joyful and it was super grounding and important for me.

I still remember Theo when he was around three, three and a half years old. Jared used to make me coffee every morning and it was like my great luxury that I would sit there. He still makes it for me every morning. I told him, I’m never, even though I secretly know how to actually work the coffee machine, but I’ve convinced him that I have no idea how to work the coffee machine. Now I’m going to be busted, but it’s a skill I don’t want to learn because it’s one of his acts of love. He brings me coffee every morning in bed while I read the newspapers.
And Theo would watch this. And so he got Jared to teach him how to make coffee. And Theo learned how to make a full-blown cappuccino.
Lex Fridman
Nice.
Nice.
Ivanka Trump
And he had so much joy and every morning bringing me this cappuccino, and I remember the sound of his little steps, like the slide. It was so cute coming down the hallway with my perfectly foamed cappuccino. Now I try to get him to make me coffee and he’s like, “Come on mom.” It was a moment in time, but we had a lot of little moments like that that were just amazing.

And they were young enough. We really kept our home life pretty sheltered from everything else. And we were able to do so because they were so young and because they weren’t connected to the internet. They were too young for smartphones, all of these things. We were able to shelter and protect them and allow them to have as normal as upbringing as was possible in the context we were living. And they brought me and continue to bring me so much, so much joy. But they were, I mean, without Jared and without the kids, it would’ve been much more lonely.

So then Joseph wanted a dog and got Simba. Theo now wants the dog and has Buster the hamster in the interim. So we’ll see.

Parenting

What advice would you give to other mothers just planning on having kids and maybe advice to yourself on how to continue figuring out this puzzle?
What advice would you give to other mothers just planning on having kids and maybe advice to yourself on how to continue figuring out this puzzle?
Ivanka Trump
I think being a parent, you have to cultivate within yourself, like hide in levels of empathy. You have to really look at each child and see them for who they are, what they enjoy, what they love, and meet them where they’re at. I think that can be enormously challenging when your kids are so different in temperament. As they get older, that difference in temperament may be within the same child, depending on the moment of the day, but it really, I think it’s actually made me a much softer person, a much better listener. I think I see people more truly for who they are as opposed to how I want them to be sometimes. And I think being a parent to three children who are all exceptional and all incredibly different has enabled that in me.

And I think being a parent to three children who are all exceptional and all incredibly different has enabled that in me.
I think for me though, they’ve also been some of my greatest teachers in that we were talking about the presence you felt when you were in the jungle and the connectivity you felt and sort of the simple joy. And I think for us as we grow older, we kind of disconnect from that. My kids have taught me how to play again. And that’s beautiful. I remember just a couple of weeks ago we had one of these crazy Miami torrential downpours and Arabella comes down, it’s around eight o’clock at night, it’s really raining. And she’s got rain boots and pajama pants on, and she’s going to take the dogs for a walk in the rain, which she had all day to walk, but she wasn’t doing it because they needed to go for a walk. She was like, “This would be fun.”
And I’m standing at the doorstep watching her and she goes out with Simba and Winter, this massive dog and this little tiny dog. And I’m watching her walk to the end of the driveway and she’s just dancing. And it’s pouring. And I took off my shoes and I went out and I joined her and we danced in the rain. And even as a preteen who normally she allowed me to experience the joy with her, and it was amazing.
We can be so much more fun if we allow ourselves to be more playful. We can be so much more present. I look at, Theo loves games, so we play a whole lot of board games, any kind of game. So it started with board games. We do a lot of puzzles. Then it became card games. I just taught him how to play poker.
Lex Fridman
Nice.

Ivanka Trump
He loves backgammon, like any kind of game. And he’s so fully in them. When he plays, he plays. My son Joseph, he loves nature. And he’ll say to me sometimes when I’m taking a picture of something he’s observing like a beautiful sunset. He’s like, “Mom, just experience it.” I’m like, “Yes, you’re right Joseph, just experience it.”

They always give you permission to sort of reignite the inner child to be a kid again. Yeah.
They always give you permission to sort of reignite the inner child to be a kid again. Yeah.
And it’s interesting what you said that the puzzle of noticing each human being, what makes them beautiful, the unique characteristics, what they’re good at, the way they want to be mentored. I often see that, especially with coaches and athletes, young athletes aspiring to be great. Each athlete needs to be trained in a different way. For example, with some, you need a softer approach. With me, I always like a dictatorial approach. I like the coach to be this menacing figure. That’s what brought out the best in me. I didn’t want to be friends with the coach. I wanted almost, it’s weird to say, but yelled at to be pushed. But that doesn’t work for everybody. And that’s a risk you have to take in the coach context of, because you can’t just yell at everybody. You have to figure out what does each person need. And when you have kids, I imagine the puzzle is even harder.
Ivanka Trump
And when they all need different things, but yet coexist and are sometimes competitive with one another. So you’ll be at a dinner table. The amount of times I get, “Well, that’s not fair. Why did you let?” And I’m like, “Life isn’t fair. And by the way, I’m not here to be fair.” I’m like, “I’m trying to give you each what you need.”

Why did you let?” And I’m like, “Life isn’t fair. And by the way, I’m not here to be fair.” I’m like, “I’m trying to give you each what you need.”
Especially when I’ve been working really hard and in the White House, I’d say, “Okay, well now we have a Sunday and we have these hours,” and I’ll have a grand plan and we’re going to make a count and it’s going to involve hot chocolate and sleds, whatever it is that my great adventure that we’re going to go play mini golf. And then I come down all psyched up, all ready to go, and the kids have zero interest. And there have been a lot of times where I’ve been like, “We’re doing this thing.” And then I realized, “Wait a second.” Sometimes you just plop down on the floor and start playing magnet tiles and that’s where they need you.
So those of us who have sort of alpha personalities who sometimes it’s just witness, witness what they need. Play with them and allow them to lead the play. Don’t force them down a road you may think is more interesting or productive or educational or edifying. Just be with them, observe them, and then show them that you are genuinely curious about the things that they are genuinely curious about. I think there’s a lot of love when you do that.
Lex Fridman
Also, there’s just fascinating puzzles. I was talking to a friend yesterday and she has four kids and they fight a lot and she generally wants to break up the fights, but she’s like, “I’m not sure if I’m just supposed to let them fight. Can they figure it out?” But you always break them up because I’m told that it’s okay for them to fight. Kids do that. They kind of figure out their own situation. That’s part of the growing up process. But you want to always, especially if it’s physical, they’re pushing each other. You want to kind of stop it. But at the same time, it’s also part of the play, part of the dynamics. And that’s a puzzle you also have to figure out. And plus, you’re probably worried that they’re going to get hurt if they’re …

Well, I think there’s like when it gets physical that’s like, “Okay, we have to intervene.” I know you’re into martial arts, but that’s normally the red line, once it tips into that. But there is always that, you have to allow them to problem solve for themselves. A little interpersonal conflict is good.

It’s really hard when you try to navigate something because everyone thinks you’re taking their sides. You have oftentimes incomplete information. I think for parents, what tends to happen too is we see our kids fighting with each other in a way that all kids do and we start to project into the future and catastrophize. If my two sons are going through a moment where they’re like oil and water, anything one wants to do the other doesn’t want to do. It’s a very interesting moment. So my instinct is they’re not going to like each other when they’re 25. You sort of project into the future as opposed to recognizing this is a stage that I too went through, and it’s normal, and it’s not building it in your mind into something that’s unnecessarily consequential.
Lex Fridman
It’s short-term formative conflict.

Ivanka Trump

Lex Fridman
So ever since 2016, the number and the level of attacks you’ve been under has been steadily increasing, has been super intense. How do you walk through the fire of that? You’ve been very stoic about the whole thing. I don’t think I’ve ever seen you respond to an attack. You just let it pass over you. You stay positive and you focus on solving problems and you didn’t engage. While being in DC you didn’t engage into the back and forth fire of the politics. So what’s your philosophy behind that?

Ivanka Trump
I appreciate you’re saying that I was very stoic about it. I think I feel things pretty deeply. So initially some of that really took me off guard, like some of the derivative love and hatred, some of the intensity of the attacks. And there were times when it was so easy to counter it. I’d even write something out and say, “Well, I’m going to press send,” and never did. I felt that sort of getting into the mud, fighting back, it didn’t run true to who I am as a human being. It felt at odds with who I am and how I want to spend my time. So I think as a result, I was oftentimes on the receiving end of a lot of cheap shots. And I’m okay with that because it’s sort of the way I know how to be in the world. I was focused on things I thought mattered more.

And I’m okay with that because it’s sort of the way I know how to be in the world. I was focused on things I thought mattered more.
And I think part of me also internalized, there’s a concept in Judaism called Lashon hara, which is translated into I think quite literally evil speech. And the idea that speaking poorly of another is almost the moral equivalent to murder because you can’t really repair it. You can apologize, but you can’t repair it. Another component of that is that it does as much damage to the person saying the words than it does to the person receiving them. And I think about that a lot. I talk about this concept with my kids a lot, and I’m not willing to pay the price of that fleeting and momentary satisfaction of sort of swinging back because I think it would be too expensive for my soul. And that’s how I made peace with it, because I think that feels more true for me.
But it is a little bit contrary in politics. It’s definitely a contrarian viewpoint to not get into the fray. Actually, some day, I love Dolly Parton says that she doesn’t condemn or criticize. She loves and accepts. And I like that. It feels right for me.
Lex Fridman
I also like that you said that words have power. Sometimes people say, “Well, words, when you speak negatively of others, ah, that’s just words.” But I think there’s a cost to that. There’s a cost, like you said, to your soul, and there’s a cost in terms of the damage it can do to the other person, whether it’s to their reputation publicly or to them privately. It just as a human being psychologically. And in the place that it puts them because they they start thinking negatively in general and then maybe they respond and there’s this vicious downward spiral that happens, that almost like we don’t intend to, but it destroys everybody in the process.

You quoted Alan Watts, I love him, in saying, “You’re under no obligation to be the same person you were five minutes ago.” So how have the years in DC and the years after changed you?
Ivanka Trump
I love Alan Watts too. I listen to his lecture sometimes falling asleep and on planes. He’s got the most soothing voice. But I love what he said about you have no obligation to be who you were five minutes ago, because we should always feel that we have the ability to evolve and grow and better ourselves.

But I love what he said about you have no obligation to be who you were five minutes ago, because we should always feel that we have the ability to evolve and grow and better ourselves.
I think further than that, if we don’t look back on who we were a few years ago with some level of embarrassment, we’re not growing enough. So there’s nothing. When I look back, I’m like, oh, I feel like that feeling is because you’re growing into hopefully sort of a better version of yourself. And I hope and feel that that’s been true for me as well. I think the person I am today, we spoke in the beginning of our discussion about some of my earliest ambitions in real estate and in fashion, and those were amazing adventures and incredible experiences in government.
And I feel today that all of those ambitions are more fully integrated into me as a human being. I’m much more comfortable with the various pieces of my personality and that any professional drive is more integrated into more simple pleasures. Everything for me has gotten much simpler and easier in terms of what I want to do and what I want to be. And I think that’s where my kids have been my teachers just being fully present and enjoying the little moments. And it doesn’t mean I’m any less driven than I was before. It’s just more a part of me than being sort of the all-consuming energy one has in their 20s.
Lex Fridman
Yeah, just like you said, with your mom be able to let go and enjoy the water, the sun, the beach, and enjoy the moment, the simplicity of the moment.

I think a lot about the fact that for a lot of young people, they really know what they want to do, but they don’t actually know who they are. And then I think as you get older, hopefully you know who you are and you’re much more comfortable with ambiguity around what you want to do and accomplish. You’re more flexible in your thinking around those things.

You made the decision not to engage in the politics of the 2024 campaign. If it’s okay, let me read what you wrote on the topic. “I love my father very much.

Lex Fridman
While I will always love and support my father, going forward, I will do so outside the political arena. I’m grateful to have had the honor of serving the American people, and I will always be proud of many of our Administration’s accomplishments. So can you explain your thinking, your philosophy behind that decision?

So can you explain your thinking, your philosophy behind that decision?
Ivanka Trump
I think first and foremost, it was a decision rooted in me being a parent, really thinking about what they need from me now. Politics is a rough, rough business and I think it’s one that you also can’t dabble in. I think you have to either be all in or all out. And I know today, the cost they would pay for me being all in, emotionally in terms of my absence at such a formative point in their life. And I’m not willing to make them bear that cost. I served for four years and feel so privileged to have done it, but as their mom, I think it’s really important that I do what’s right for them. And I think there are a lot of ways you can serve.

Obviously, we talked about the enormity, the scale of what can be accomplished in government service, but I think there’s something equally valuable about helping within your own community. And I volunteer with the kids a lot and we feel really good about that service. It’s different, but it’s no less meaningful. So I think there are other ways to serve. I also think for politics, it’s a pretty dark world. There’s a lot of darkness, a lot of negativity, and it’s just really at odds with what feels good for me as a human being. And it’s a really rough business. So for me and my family, it feels right to not participate.
Lex Fridman
So it wears on your soul, and yeah, there is a bit, at least from an outsider’s perspective, a bit of darkness in that part of our world. I wish it didn’t have to be this way.

What I love about her, and I’ve really come to love her in recent years is she’s so authentically herself and she’s obviously so talented and so accomplished and this extraordinary woman, but I just feel like she has no conflict within herself as to who she is. She reminds me a lot of my mom in that way, and it’s super refreshing and really beautiful to observe somebody who’s so in the public eye being so fully secure in who they are, what their talent is, and what drives them. So I think she’s amazing. And she leads with a lot of love and positivity. So I think she’s very cool. I hope you have a long conversation with her.

Adele
Alice Johnson
Ivanka Trump
Yeah, I mean, she’s extraordinary. Her voice is unreal. So I find her to be so talented. And she’s so unique in that three year olds love her music. She was actually the first concert Arabella ever went to at Madison Square Garden when she was around four. And 90-year-olds love her music. And that’s pretty rare to have that kind of bandwidth of resonance. So I think she’s so talented. We actually just saw her, I took all three kids in Las Vegas around a month ago. Alice Johnson, whose case I had worked with in the White House, my father commuted her sentence, her case was brought to me by a friend, Kim Kardashian, and she came to the show. We all went together with some mutual friends. And that was a very profound… It was amazing to see Adele, but it was a very profound experience for me to have with my kids because she rode with us in the car on the way to the show, and she talked to my kids about her experience and her story and how her case found its way to me.

And I think for young children, it’s very abstract, policy. And so for her to be able to share with them this was a very beautiful moment and led to a lot of really incredible conversations with each of my kids about our time and service because they gave up a lot for me to do it. Actually, Alice told them the most beautiful story about the plays she used to put on in prison, how these shows were the hottest ticket in town. You could not get into them, they always extended their run. But for the people who were in them, a lot of those men and women had never experienced applause. Nobody had ever shown up at their games or at their plays and clapped for them. And the emotional experience of just being able to give someone that, being able to stand and applaud for someone and how meaningful that was. And she was showing us pictures from these different productions and it was a beautiful moment.
Alice actually, after her sentence was commuted and she came out of prison, together, we worked on 23 different pardons or commutations. So the impact of her experience and how she was able to take her opportunity and create that same opportunity for others who were deserving and who she believed in was very beautiful. So anyway, that was an extraordinary concert experience for my kids to be able to have that moment.
Lex Fridman
What a story. So that’s the…

Yeah. I mean, you mentioned also there, I’ve seen commutations where it’s an opportunity to step in and consider the ways that the justice system does not always work well like in cases when it’s nonviolent crime and drug offenses, there’s a case of a person you mentioned that received a life sentence for selling weed. And it’s just the number… It’s like hundreds of thousands of people are in the federal prison, in jail, in the system for selling drugs. That’s the only thing. With no violence on their record whatsoever. Obviously, there’s a lot of complexity. There’s the details matter, but oftentimes, the justice system does not do right in the way we think right is, and it’s nice to be able to step in and help people indirectly.

They’re overlooked and they have no advocate. Jared and I helped in a small way on his effort, but he really spearheaded the effort on criminal justice reform through the First Step Act, which was an enormously consequential piece of legislation that gave so many people another opportunity, and that was amazing. So working with him closely on that was a beautiful thing for us to also experience together. But in the final days of the administration, you’re not getting legislation passed and anything you do administratively is going to be probably overturned by an incoming administration. So how do you use that time for maximum results?

And I really dug in on pardons and commutations that I thought were overdue and were worthy. And my last night in Washington, D.C., the gentleman you mentioned, Corvin, I was on the phone with his mother at 12:30 in the morning, telling her that her son would be getting out the next day. And it felt really… It’s one person. But you see with Alice, the ripple effect of the commutation granted to her and her ability and the impact she’ll have within her family, with her grandkids. And now, she’s an advocate for so many others who are voiceless. It felt like the perfect way to end four years, to be able to call those parents and call those kids in some cases and give them the news that a loved one was coming home.
Lex Fridman
And I just love the cool image of you, Kim Kardashian, and Alice just dancing on Adele’s show with the kids. I love it.

The way Adele can hold just the badassness she has on stage, she does heartbreak songs better than anyone. Or no, it’s not even heartbreak. What’s that genre of song, like Rolling in the Deep, like a little anger, a little love, a little something, a little attitude, and just one of the greatest voices ever. All that together just her by herself.

Yeah, you can strip it down and the power of her voice. I think about that. One of the things we were talking about live music, one of the amazing things now is there’s so much incredible concert material that’s been uploaded to YouTube. So sometimes I just sit there and watch these old shows. We both love Stevie Ray Vaughan, like watching him perform. You can even find old videos of Django Reinhardt.

Well, my bucket list is to learn how to play it.

Lex Fridman
It’s a bucket list. This is a bucket list item. You made me feel so good because for me, Texas Flood was the first solo on guitar I’ve ever learned because for me, it was the impossible solo. And then so I worked really hard to learn it. It’s like one of the most iconic sort of blues songs, Texas blues songs. And now, you made me fall in love with the song again and want to play it out live, at the very least, put it up on YouTube because it’s so fun to improvise. And when you lose yourself in the song, it truly is a blues song. You can have fun with it.

… one of my favorites to see live. And there’s so many incredible songwriters and musicians that are out there touring today, but I think you also, you can go online and watch some of these old performances. Like Django Reinhardt was the first, because I torture myself, was the first song I learned to play on the guitar and it took me nine months to a year. I mean, I should have chosen a different song, but Où es-tu mon amour?, one of his songs, was… And it was like finger style and I was just going through and grinding it out. And that’s kind of how I started to learn to play, by playing that song. But to see these old videos of him playing without all his fingers and the skill and the dexterity, one of my favorite live performances is actually who really influenced Adele is Aretha Franklin. And she did a version of Amazing Grace. Have you ever seen this video?

Ivanka Trump
Yeah. And you can take away all the instruments with Adele and just have that voice and it’s so commanding and it’s so… Anyway, you watch this and you see the arc of also the experience of the people in the choir and them starting to join in. And anyway, it’s amazing.

So good. Well, we were talking surfing, we were talking jiu-jitsu. I think live music is one of those kind of rare moments where you can really be present, where something about the anticipation of choosing what show you’re going to go to and then waiting for the date to come. And normally, it happens in the context of community. You go with friends and then allowing yourself to sort of fall into it is incredible.

Yeah. I mean, what do you like about jiu-jitsu?
Ivanka Trump
Well, first of all, I love the way I came to it. It was my daughter. I think I told you this story. At 11, she told me that she wanted to learn self-defense, and she wanted to learn how to protect herself, which I just, as a mom, I was so proud about because at 11, I was not thinking about defending myself. I loved that she had sort of that desire and awareness. So I called some friends, actually a mutual friend of ours, and asked around for people who I could work with in Miami, and they recommended the Valente Brothers’ studio. And you’ve met all three of them now. They’re these remarkable human beings, and they’ve been so wonderful for our family. I mean, first, starting with Arabella, I used to take her and then she’d kind of encouraged me and she’d sort of pull me into it and I started doing it with her. And then Joseph and Theo saw us doing it, they wanted to start doing it. So now they joined and then Jared joined. So now, we’re all doing jiu-jitsu.

Lex Fridman
Mm-hmm. That’s great.
Mm-hmm. That’s great.
Ivanka Trump
And for me, there’s something really empowering, knowing that I have some basic skills to defend myself. I think it’s something, as humans, we’ve kind of gotten away from. When you look at any other animal and even the giraffe, they’ll use their neck, the lion, the tiger, every species. And then there’s us, who most of us don’t. And I didn’t know how to protect myself. And I think that it gives you a sense of confidence and also gives you kind of a sense of calm, knowing how to de-escalate rather than escalate a situation. I also think as part of the training, you develop more natural awareness when you’re out and about.

And I feel like especially everyone’s… You get on an elevator and the first thing people do is pick up their phone. You’re walking down the street, people are getting hit by cars because they’re walking into traffic. I think as you start to get this training, you become much more aware of the broader context of what’s happening around you, which is really healthy and good as well. But it’s been beautiful. Actually, the Valente Brothers, they have this 753code that was developed with some of the samurai principles in mind. And all of my kids have memorized it and they’ll talk to me about it. Theo, he’s eight years old, he’s able to recite all 15. So benevolence and fitness and nutrition and flow and awareness and balance. And it’s an unbelievable thing. And they’ll actually integrate it into conversations where they’ll talk about something that… Yeah, rectitude, courage.
Lex Fridman
Benevolence, respect, honesty, honor, loyalty. So this is not about jiu-jitsu techniques or fighting techniques. This is about a way of life, about the way you interact with the world with other people. Exercise, nutrition, rest, hygiene, positivity, that’s more on the physical side of things. Awareness, balance, and flow.

It’s the mind, the body, the soul, effectively, is how they break it out. And the kids can only advance and get their stripes if they really internalize this, they give examples of each of them. And my own kids will come home from school and they’ll tell me examples of how things happened that weren’t aligned with the 753code. So it’s a framework much like religion is in our house and can be for others. It’s a framework to discuss things that happen in their life, large and small, and has been beautiful. So I do think that body-mind connection is super strong in jiu-jitsu.

Lex Fridman
So there’s many things I love about the Valente Brothers, but one of them is the how rooted it is in philosophy and history of martial arts in general. A lot of places, you’ll practice the sport of it, maybe the art of it, but to recognize the history and what it means to be a martial artist broadly on and off the mat, that’s really great. And the other thing that’s great is they also don’t forget the self-defense root, the actual fighting roots. So it’s not just a sport, it’s a way to defend yourself on the street in all situations. And that gives you a confidence in, just like you said, an awareness about your own body and awareness about others. Sadly, we forget, but it’s a world full of violence or the capacity for violence. So it’s good to have an awareness of that and the confidence how to essentially avoid it.

100%. I’ve seen it with all of my kids and myself, how much they’ve benefited from it. But that self-defense component and the philosophical elements of… Pedro will often tell them about wuwei and sort of soft resistance and some of these sort of more eastern philosophies that they get exposed to through their practice there that are sort of non-resistance, that are beautiful and hard concepts to internalize as an adult, but especially when you’re 12, 10, and 8 respectively. So it’s been an amazing experience for us all.

Lex Fridman
I love people like Pedro because he’s finding books that are in Japanese and translating them to try to figure out the details of a particular history. He’s an ultra scholar of martial arts, and I love that. I love when people give everything, every part of themselves to the thing they’re practicing. People have been fighting each other for a very long time. From the Colosseum on. You can’t fake anything. You can’t lie about anything. It’s truly honest. You’re there and you either win or lose. And it’s simple. And it’s also humbling, that the reality of that is humbling.

So it’s nice to have that sometimes. That’s the biggest thing I gained from jiu-jitsu, is getting my ass kicked, was the humbling. And it’s nice to just get humbled in a very clear way. Sports in general are great for that. I think surfing probably because I can imagine just face planting, not being able to stay on the board. It’s humbling. And the power of the wave is humbling. So just like your mom, you’re an adventurer. Your bucket list is probably like 120 pages.

Well, I hope it always is long. I hope I’ve never exhausted exploring all the things I’m curious about. I always tell my kids whenever they say, “Mom, I’m bored.”, “Only boring people get bored.” There’s too much to learn. There’s too much to learn. So I’ve got a long one. I think, obviously, there are some immediate tactical, interesting things that I’m doing. I’m incubating a bunch of businesses, I’m investing in a bunch of companies that hopefully I’ll always can continue to do that. Some of the fun things I’m doing in real estate now. So those are all on the list of things I’m passionate and excited about, continuing to explore and learn. But in terms of the ones that are more pure sort of adventure or hobby, I think I’d like to climb Mount Kilimanjaro. Actually, I know I would. And the only thing keeping me from doing it in the short-term is I feel like it’d be such a great experience to do with my kids and I’d love to have that experience with them.

I also told Arabella, we were talking about this archery competition that happens in Mongolia, and she loves horseback riding. So I’m like, I feel like that would be an amazing thing to experience together. I want to get barreled by a wave and learn how to play Texas Flood. I want to see the Northern Lights. I want to go and experience that. I feel like that would be really beautiful. I want to get my black belt.
Lex Fridman
Black belt? Nice.
Black belt? Nice.
Ivanka Trump
I asked you, “How long did it take?” So I want to get my black belt in jiu-jitsu. That’s going to be a longer-term goal, but within the next decade. Yeah.

Ivanka Trump
I think being interplanetary, my hope is that that heightens for us how rare it is what we have, how precious the Earth is. I hope that it has that effect because I think there’s a big component to interplanetary travel that kind of taps into this kind of manifest destiny inclination, like the human desire to conquer territory and expand the footprint of civilization. That sometimes feels much more rooted in dominance and conquest than curiosity, wonder. And obviously, I think there’s maybe an existential imperative for it at some point, or a strategic and security one. But I hope that what feels inevitable at this moment, I mean, you know Elon Musk and what he’s doing with SpaceX and Jeff Bezos and others, it feels like it’s not an if, it’s a when at this point. I hope it also underscores the need to protect what we have here.

Yeah. I hope it’s the curiosity that drives that exploration. And I hope the exploration will give us a deeper appreciation of the thing we have back home, and that Earth will always be home and it’s a home that we protect and celebrate. What gives you hope about the future of this thing we have going on? Human civilization, the whole thing.

The following is a conversation with Andrew Huberman, his fifth time on the podcast. He is the host of the Huberman Lab podcast and is an amazing scientist, teacher, human being, and someone I’m grateful to be able to call a close friend. Also, he has a book coming out next year that you should pre-order now, called Protocols: An Operating Manual for the Human Body. This is the Lex Freeman podcast. To support it, please check out our sponsors in the description. And now, dear friends, here’s Andrew Huberman.
You think there’s ever going to be a day when you walk away from podcasting?
In fact, the greatest scientists, people like Richard Axel, Catherine Dulac, there are many other labs in neuroscience, Karl Deisseroth. They’re not just known for doing great science. They’re known for mentoring some of the best scientists that then go on to start their own labs. And I think in podcasting, I am very fortunate I got in a fairly early wave, not the earliest wave, but thanks to your suggestion of doing a podcast, fairly early wave. And I’ll continue to go as long as it feels right, and I feel like I’m doing good in the world and providing good, but I’m already starting to scout talent.
My company that I started with, Rob Moore, SciCom Media, there’s a couple other guys in there too. Mike Blabac, our photographer, Ian Mackey, Chris Ray, Martin Phobes. We are a company that produces podcasts right now. That’s Huberman Lab podcast, but we’re launching a new podcast, Perform with Dr. Andy Galpin.
I mean, again, I saw this in skateboarding like Danny and Colin and Danny’s brother Damon started DC with Ken Block, the driver who unfortunately passed away a little while ago, rally car driver. And they eventually sold it, I think to Quicksilver or something like that. But they’re all phenomenal talents in their respective areas. But they brought in the next line of amazing riders. The plan B thing. Paul Rodriguez for skateboarders, they know who this is now in science, there are scientists like Feynman for instance, I don’t know if anyone can name one of his mentor offspring. So there are scientists who are phenomenal, beyond world-class, multi-generational, world-class, who don’t make good mentors. I’m not saying he wasn’t a good mentor, but that’s not what he’s known for.
And then there are scientists who are known for being excellent scientists and great mentors. And I think there’s no higher celebration to be had at the end of one’s career, if you can look back and be like, “Hey, I’ve put some really important knowledge into the world. People made use of that knowledge.” And guess what? You spawned all these other scientific offspring or sport offspring or podcast offspring. I mean in some ways we look to Rogan and to some of the other earlier podcasters, they paved the way. Rhonda Patrick, first science podcast out there. So eventually the baton passes, but fortunately right now everybody’s active and it feels really good.
And there are other examples. Einstein, people described him as taking walks around the Princeton campus, then pausing, and would ask him what was going on and the idea that his mind was continuing to churn forward at a higher rate. So this is far from controlled studies, but we’re talking about some incredible minds and creatives who have a practice of stilling the body while keeping the mind deliberately very active, very similar to rapid eye movement sleep. And then there are a lot of people who also report great ideas coming to them in the shower, while running. So it can be the opposite as well, where the body is very active and the mind is perhaps more on kind of like a default mode network, not really focusing on any one specific thing.
And he had some other conditions that we worked out and I felt like, “Cool, he’s really interested.” You get a very different person on the phone than you do on Twitter. I will say he’s been very collegial and that conversation is on the schedule. I said, “We’ll fly you out, we’ll put you up.” He said, no, he wants to fly himself. He really wants to make sure that there’s a space between, I think some of the perception of science and health podcasts in the academic community is that it’s all designed to sell something. No, we run ads so it can be free to everyone else.
But I think, look, in the end, he agreed, and I’m excited for the conversation. It was interesting because in the wake of that little exchange, there’s been a bunch of press from traditional press about cannabis has now surpassed alcohol in many cultures within the United States as, when I say cultures, I mean demographics, the United States as the drug of choice. There have been people highlighting the issues of potential psychosis in high THC containing. And so it’s kind interesting to see how traditional media is sort of onboard certain elements that I put forward. And I think there’s some controversy as to whether or not the different strains, the indicas and sativas are biologically different, et cetera. So we’ll get down into the weeds, pun intended, during that one. And I’m excited. It’s the first time that we’ve responded to a direct criticism online about scientific content in a way that really promoted the idea of inviting a particular guest.
And so it’s great. Let’s get a guest on who is an expert in cannabis. I believe, I could be wrong about this, but he’s a behavioral neuroscientist. That’s slightly different training. But look, he seems highly credentialed. It’ll be fun. And we welcome that kind of exchange.
But hopefully if they do it, they’re willing to back it up, with knowledge in this case, we’re not talking about physical altercation. He kept coming and he kept putting on conditions, “How do I know you want this?” And I was like, “Well, you can record the conversation.” “How do I know you want that?” “Listen, we’ll pay for you to come out.” “How do you know…?” And eventually he just kind of relented. And to his credit, he’s agreed to come on. I mean, he still has to show up, but once he does, we’ll treat him right, like we would any other guest.
I think ultimately Twitter’s a record of people’s behavior. The internet is a record of people’s behavior. And here I’m not talking about news reports about people’s behavior. I’m talking about how people show up online is really important. You’ve always carried yourself with a ton of composure and respect, and you would hope that people would grow from that example.
Well, I’ll tell you that the podcasters that I’m scouting, it’s their energy, but it’s also how they treat other people, how they respond to comments. And we’re blessed to have pretty significant reach. When we put out a podcast of someone else’s podcast, it goes far and wide. So like a skateboard team, like a laboratory where you’re selecting people to be in your lab, you want to pick people that you would enjoy working with and that are collegial. Etiquette is lacking nowadays, but you’re in the suit and tie. You’re bringing it back.
So it’s always been a dream of mine to meet him and to record a podcast. And he wasn’t able to travel. So our team went out to DC and sat down with him. We rarely do that nowadays. People come to our studio. And he came in, he had some surgeries recently, and he kind of came in with some assistance from a cane and then sat down and just blew my mind. From start to finish he didn’t miss a syllable. And every sentence that he spoke was like a quotable sentence of with real potency and actionable items. I think one of the things that was most striking to me was how he said, when we take ourselves out of stimulus and response and we just force ourselves to spend some time in the quiet of our thoughts while walking or while seated or while lying down, doesn’t have to be meditation, but it could be, that we access our unconscious mind in ways that reveals to us who we really are and what we really want.
And that if we do that practice repeatedly 10 minutes a day here, 15 minutes a day there, that we start to really touch into our unique gifts and the things that make us each us and the directions we need to take. But that so often we just stay in stimulus response. We just do, do, do, which is great. We have to be productive, but we miss those important messages. And interestingly, he also put forward this idea of what is, it’s like, “Get up, shut up, suit up,” something like that. Get out of bed, suit up and shut up and get to work. He also has that in him, kind of a Goggins type mindset.
If I do that for a little while, my mind starts churning on the nervous system and biology. And then, I come up with areas I’d like to explore for the podcast, ways I’d like to address certain topics. Right now, I’m very interested in autonomic control. A beautiful paper came out that shows that anyone can learn to control their pupil sizes and without changing luminance through a biofeedback mechanism. That gives them control over their so-called automatic autonomic nervous system. I’ve been looking at what the circuitry is and it’s beautiful.
So I’ll draw the circuitry that we know underlies autonomic function. As I’m doing that, I’m thinking, “Oh, what about autonomic control and those people that supposedly can control their pupil size?” Then you go in and there’s a paper published in Nature Press, one of the nature journals, and there’s a recent paper on this like, “Oh, cool.” And then, we talk about this and then how could this be put into a post or how could this… So doing things that are about 15 degrees off center from your main thing is a great way to access, I believe, the circuits for, in Tim’s case, painting goes to songwriting. I think for Joni Mitchell, that was also the case, right? I think it was drawing and painting to singing and songwriting. For Rick, I don’t know what it is. Maybe it’s listening to podcasts. I don’t know. That’s his business. Do you have anything that you like to focus on that allows you then an easier transition into your main creative work?
Some of the peptides are interesting however. There’s one that I’ve experimented with a little bit called Pinealon which I, find even if I’ve just taken it twice a week before sleep, then it times… It seems to do something to the circadian timekeeping mechanism. Because then on other days when I don’t take it, I get unbelievably tired at that time that normally I would do the injection. These are things that I’ll experiment with for a couple of weeks and then typically stop, maybe try something else. But I stay out of things that really stimulate any major hormone pathways when it comes to peptides.
I also just generally try and avoid taking peptides that tap into these hormone pathways because you can run into all sorts of issues. But some people take them safely. But usually after about four or five days, I know if I like something or I don’t and then I move on. But I’m not super adventurous with these things. I know people that will take cocktails of peptides with multiple things. They’ll try anything. That’s not me and I do blood work. But also, I’m mainly reading papers and podcasting and I’m teaching a course next spring. In Stanford, I’m going to do a big undergraduate course. So I’m trying to develop that course and things like that. So I don’t need to lift more weight or run further than I already do which is not that much weight or far as it is.
We’re not talking about I’m smoking, vaping, dipping, or snuffing. My interest in nicotine started… This was in 2010, I was visiting Columbia Medical School and I was in the office of the great neurobiologist, Richard Axel. Won the Nobel Prize, co-recipient with Linda Buck, for the discovery of the molecular basis of olfaction. Brilliant guy. He’s probably in his late 70s now.
And so, there was a clip that was cut in which I was describing cumulative probability. By the way, we’ve published cumulative probability histograms in many of my laboratories’ papers, including one that was in Nature Article in 2018. So we run these all the time. Yes, I know the difference between independent and cumulative probability. I do.
The way the clip was cut and what I stated unfortunately combined to a pretty great gaffe where I said, “You’re just adding percentages 20 to 120%.” And then, I made this… Unfortunately, my humor isn’t always so good and I made a joke. I said, “120%, but that’s a different thing altogether.” What I should have said was, “That’s impossible and here’s how it actually works.” But then, it continues where I then describe the cumulative probability histogram for successful pregnancy.
But somewhere in the early portion, I misstated something, right? I made a math error which implied I didn’t understand the difference between independent and cumulative probability which I do. It got picked up and run and people had a really good laugh with that one at my expense. And so, what I did in response to it was rather than just say everything I just said now, I just came out online and said, “Hey folks, in an episode dated this on fertility, I made a math error. Here’s the formula for cumulative probability, successful pregnancy at that age. Here’s the graph. Here’s the…”
I offered it as a teaching moment in two ways. One, for people to understand cumulative probability. It was interesting too, the number of people that had come out critiquing the gaffe. Also, like Balaji and folks came out pointing out that they didn’t understand cumulative probability. So there was a lot of posturing. The dogpile, oftentimes people are quick to dogpile. They didn’t understand but a lot of people did understand. There’s some smart people out there obviously. I called my dad and he was just laughing. He goes, “Oh, this is good. This is like the old school way of hammering academics.”
But the point being, it was a teaching moment. Gave me an opportunity to say, “Hey, I made a mistake.” I also made a mistake in another podcast where I did a micron to millimeter conversion or centimeter conversion. We always correct these in the show note captions. We correct them in the audio now. Unfortunately, on YouTube, it’s harder to correct. You can’t go and edit in segments. We put it in the captions but that was the one teaching moment. If you make a mistake, it’s substantive and relate to data, you apologize and correct the mistake. Use it as a teaching moment.
The other one was to say, “Hey…” In all the thousands of hours of content we’ve put out, I’m sure I’ve made some small errors. I think I once said serotonin when I meant dopamine and you’re going, you’re riffing. It’s a reminder to be careful to edit, double check. But the internet usually edits for us and then we go make corrections.
But it didn’t feel good at first. But ultimately, I can laugh at myself about it. Long ago at Berkeley when I was TA-ing my first class, it was a bio-psychology class. It should be in 1998 or 1999. I was drawing the pituitary gland which has an anterior and a posterior lobe. It actually as a medial lobe too. I had 5, 600 students in that lecture hall. I drew, it was chalkboard and I drew the two lobes of the pituitary and I said… My back was to the audience, I said, “And so, they just hang there,” and everyone just erupted in laughter because it looked like a scrotum with two testicles. I remember thinking like, “Oh my god. I don’t think I can turn around and face this.” I got to turn around sooner or later so I turned around and we just all had a big laugh together. It was embarrassing. I’ll tell you one thing though, they never forgot about the two lobes of the pituitary.
I did an episode on oral health. I didn’t know this until I researched that episode but oral health is critically related to heart health and brain health. That there’s a bacteria that causes cavities, streptococcus, that can make its way into other parts of the body through the mouth that can cause serious issues. There’s the idea that some forms of dementia, some forms of heart disease start in the mouth basically. I talked to no fewer than four dentists, dental experts, and there was a lot of convergence.
I also learned that teeth can demineralize, that’s the formation of cavities. They can also re-mineralize. As long as the cavity isn’t too deep, it can actually fill itself back in, especially if you provide the right substrates for it. That saliva is this incredible fluid that has all this capacity to re-mineralize teeth, provided the milieu is right. Things like alcohol-based mouth washes, killing off some of the critical things you need. It was fascinating and I put out that episode thinking, “Well, I’m not a dentist. I’m not an oral health episode but I talked to a pediatric dentist.” There’s a terrific one, Dr. Downskor Staci, S-T-A-C-I, on Instagram, does great content. Talked to some others.
And then, I just waited for the attack. I was like, “Here we go,” and it didn’t come. Dentists were thanking me. I was like… That’s a rare thing. More often than not, if I do an episode about, say, psilocybin or MDMA, you get some people liking it. Or ADHD and the drugs for ADHD, we did a whole episode on the Ritalin, Vyvanse, Adderall stuff. You get people saying, “Thank you. I prescribed this to my kid and it really helps.” But they’re private about the fact that they do it because they get so much attack from other people. So I like to find the center of mass, report that, try and make it as clear as possible. And then, I know that there’s some stuff where I’m going to catch shit.
What’s frustrating for me is when I see claims that I’m against fluoridization of water. Which I’m not, right? We talked about the benefits of fluoride. It builds hyper strong bonds within the teeth. I went and looked at some of literally the crystal… Excuse me. Not the crystal structure. But essentially, the micron and sub micron structure of teeth is incredible and where fluoride can get in there and form these super strong bonds. You can also form them with things like hydroxyapatite and, “Why is there fluoride in water?” “Well, it’s the best…” Okay. You say some things that are interesting. But then, somehow it gets turned into like you’re against fluoridization which I’m not.
I’ve been accused of being against sunscreen. I wear mineral-based sunscreen on my face. I don’t want to get skin cancer or I use a physical barrier. There is a cohort of people out there that think that all sunscreens are bad. I’m not one of them. I’m not what’s called a sunscreen truther. But then, you get attacked for… So we’re talking about, there are certain sunscreens that are problematic so what… Rhonda Patrick’s now starting to get vocal about this. And so, there are certain topics it’s interesting for which you have to listen carefully to what somebody is saying but there’s a lumper or lumping as opposed to splitting of what health educators say.
And so, it just seems like, like with politics, there’s this urgency to just put people into a camp of expert versus renegade or something. It’s not like that. It’s just not like that. So the short answer is, I really strive, really strive to get things right, but I know that I’m going to piss certain people off. You’ve taught me and Joe’s taught me and other podcasters have taught me. That if you worry too much about it, then you aren’t going to get the newest information out there. Like peptides, there’s very little human data, unless you’re talking about Vyleesi or the Melana… The stuff in the alpha- melanocyte stimulating hormone stuff which are prescribed for female libido to enhance female libido or Sermorelin which is for certain growth hormone deficiencies. With rare exception, there’s very little human data. But people are still super interested and a lot of people are taking and doing these things so you want to get the information out.
Also, one of the most controversial topics nowadays is Ozempic, Mounjaro. I’m very middle-of-the-road on this. I don’t understand why the “health wellness community” is so against these things. I also don’t understand why they have to be looked at as the only route. For some people, they’ve really helped them lose weight, and yes, there can be some muscle loss and other lean body loss, but that can be offset with resistance training. They’ve helped a lot of people. And other people are like, “No, this stuff is terrible.”
I think the most interesting thing about Ozempic, Mounjaro is that they are GLP-1. They’re in the GLP-1 pathway, glucagon-like peptide-1, and it was discovered in Gila monsters, which is a lizard basically, and now the entomologists will dive on me. It’s a big lizard-looking thing that doesn’t eat very often, and they figured out that there’s this peptide that allows it to curb its own appetite at the level of the brain and the gut, and it has a lot of homology to, sequence homology, to what we now call GLP-1.
So I love any time there’s animal biology links to cool human biology links to a drug that’s powerful that can help people with obesity and type 2 diabetes, and there’s evidence they can even curb some addictions. Those are newer data. But I don’t see it as an either/or. In fact, I’ve been a little bit disappointed at the way that the, whatever you want to call it, health wellness, biohacking community has slammed on Ozempic, Mounjaro. They’re like, “Just get out and run and do…”
Listen, there are people who are carrying substantial amounts of weight that running could injure them. They get on these drugs and they can improve, and then hopefully they’re also doing resistance training and eating better, and then you’re bringing all the elements together.
What I would like to see in politics and in health is neither right nor left, but what we can just call a league of reasonable people that looks at things on an issue-by-issue basis and fills in the center because I think most people are in the… I don’t want to say center in a political way, but I think most people are reasonable, they want to be reasonable, but that’s not what sells clicks. That’s not what not drives interest.
But I’m a very… I look at issue by issue, person by person. I don’t like ingroup-outgroup stuff. I never have. I’ve got friends from all walks of life. I’ve said this on other podcasts and it always sounds like a political statement, but the push towards polarization, it’s so frustrating. If there’s one thing that’s discouraging to me as I get older each year, I’m like, “Wow, are we ever going to get out of this polarization?”
Speaking of which, how are you going to vote for the presidential election?
So I think there’s something magical about two, three, four hours, but it doesn’t have to be that long, but it has to have that feeling to it where there’s not people standing around and everybody’s nervous and you’re going to be strictly sticking to the question-and-answer type of feel, but just shooting shit, which Rogan is the best by far in the world at that.
I agree that long-form conversation is a whole other business, and I think that people want and deserve to know the people that are running for office in a different way and to really get to know them. Well, listen, I guess you… I mean, is it clear that he’s going to do jail time or maybe he gets away with a fine?
Here’s one thing that I found really interesting in this whole political landscape. When I’m in Los Angeles, I often get invited to these, they’re not dinners, but gatherings where a local bunch of podcasters will come together, but a lot of people from the entertainment industry, big agencies, big tech, like big, big tech, many of the people have been on this podcast, and they’ll host a discussion or a debate.
And what you find if you look around the room and you talk to people is that about half the people in the room are very left-leaning and very outspoken about that and they’ll tell you exactly who they want to see win the presidential race, and the other half will tell you that they’re for the other side. A lot of people that people assume are on one side of the aisle or the other are in the exact opposite side.
Now, some people are very open about who they’re for, but it’s been very interesting to see how when you get people one-on-one, they’re telling you they want X candidate to win or Y candidate to win, and sometimes I’m like, “Really? I can’t believe it. You?” They’re like, “Yep.”
And so it’s what people think about people’s political leanings is often exactly wrong, and that’s been eyeopening for me. And I’ve seen that in university campuses too. And so it’s going to be really, really interesting to see what happens in November.
And I think that God willing, we’re going to… Some young guy or woman is on this and refuses to back down and was just determined to be president and will make it happen, but I don’t even know who the viable candidates are. Maybe you, Lex. You know? We should ask Saagar. Saagar would know.
In 2017, went back down there, and that was the year that I exited the cage. You lower the cage with a crane, and that year, I exited the cage. I had a whole mess with a air failure the day before. I was breathing from a hookah line while in the cage. I had no scuba on. Divers were out. The thing got boa-constricted up and I had an air failure and I had to actually share air and it was a whole mess. A story for another time.
But the next day, because I didn’t want to get PTSD and it was pretty scary, the next day I cage-exited with some other divers. And it turns out with these great white sharks, in Guadalupe, the water’s very clear and you can swim toward them and then they’ll veer off you if you swim toward them. Otherwise, they see you as prey.
Well, in the evening, you’ve brought all the cages up and you’re hopefully all alive. And we were hanging out, fishing for tuna. We had one of the crew on board had a line in the water and was fishing for tuna for dinner, and a shark took the tuna off the line, and it’s a very dramatic take. And you can see the just absolute size of these great white sharks. The waters there are filled with them.
That’s the one. So this video, just the Neuralink link, was shot by Matt MacDougall, who is the head neurosurgeon at Neuralink. There it is. It takes it. Now, believe it or not, it looks like it missed, like it didn’t get the fish. It actually just cut that thing like a band saw. I’m up on the deck with Matt.
But what’s interesting is that if you look at how they move through the water, all it takes for one of these great white sharks when it sees a tuna or something it wants to eat, is two flicks of the tail and it becomes like a missile. It’s just unbelievable economy of effort.
And Ocean Ramsey, who is, in my opinion, the greatest of all cage-exit shark divers, this woman who dove with enormous great white sharks, she really understands their behavior, when they’re aggressive, when they’re not going to be aggressive. She and her husband, Juan, I believe his name is, they understand how the tiger sharks differ from the great white sharks.
We were down there basically not understanding any of this. We never should have been there. And actually, the air failure the day before, plus cage-exiting the next day, I told myself after coming up from the cage exit, “That’s it. I’m no longer taking risks with my life. I want to live.” Got back across the border a couple days later, and I was like, “That’s it. I don’t take risks with my life any longer.”
But yeah, MacDougall, Matt MacDougall shot that video and then it went “viral” through Nature is Metal. We passed them that video.
But here we are back to dark stuff again. I like the Shark Attack Map, and the Shark Attack Map shows that Northern California, there were a couple. Actually, a guy’s head got taken off. He was swimming north of San Francisco. There’s been a couple in Northern California. That was really tragic, but most of them are in Florida and Australia.
He’s just… Three members of the party chose to go in. Njai was in this chest-high water, 25 to 50 yards from shore, great white breached the water, seized his head, and that was it.
So it does happen. It’s very infrequent. If you don’t go in the ocean, it’s a very, very, very low probability, but-
Yeah, I spend far too much time thinking about and learning about the visual systems of different animals. If you get me going on this, we’ll be here all night.
Anyway, I thought we were going to bring up something happy.
See, this is the difference between Russian Americans and Americans. It’s like maybe this is actually a good time to bring up your ayahuasca journey. I’ve never done ayahuasca, but I’m curious about it. I’m also curious about ibogaine, iboga, but you told me that you did ayahuasca and that for you, it wasn’t the dark, scary ride that it is for everybody else.
Now, it’s always full-spectrum light, but because of some atmospheric elements and because of the low solar angle, that difference between the different wavelengths of light is the fundamental signal that the neurons in your eye pay attention to and signal to your circadian timekeeping mechanism. At the core of our brain in the suprachiasmatic nucleus, we are wired to be entrained to the rising and setting of the sun. That’s the biological timer, which makes perfect sense because obviously, as the planet spin and revolve-
Of course, even under the canopy during the daytime, there’s far more photons than at night. This is always what I’m telling people to get sunlight in their eyes in the morning and in the evening. People say, “There’s no light, no sunlight this time here.” I’m like, “Go outside on a really overcast day. It’s far brighter than it is at night.” So there’s still lots of sunlight, even if you can’t see the sun as an object.
But I love time perception shifts. And you mentioned that in the jungle, it’s linked to the rising and setting of the sun. You also mentioned that on ayahuasca, you zoomed out from the Earth. These are, to me, the most interesting aspects of having a human brain as opposed to another brain. Of course, I’ve only ever had a human brain, which is that you can consciously set your time domain window. We can be focused here, we can be focused on all of Austin, or we can be focused on the entire planet. You can make those choices consciously.
But in the time domain, it’s hard. Different activities bring us into fine-slicing or more broad-bending of time depending on what we’re doing, programming or exercising or researching or podcasting. But just how unbelievably fluid the human brain is in terms of the aperture of the time-space window, of our cognition, and of our experience.
And I feel like this is perhaps one of the more valuable tools that we have access to that we don’t really leverage as much as we should, which is when things are really hard, you need to zoom out and see it as one element within your whole lifespan. And that there’s more to come.
I mean, people commit suicide because they can’t see beyond the time domain they’re in or they think it’s going to go on forever. When we’re happy, we rarely think this is going to last forever, which is an interesting contrast in its own right. But I think that psychedelics, while I have very little experience with them, I have some, and it sounds like they’re just a very interesting window into the different apertures.
Ibogaine, as I understand it, gives a 22-hour psychedelic journey where no hallucinations with the eyes open, but you close your eyes and you get a very high-resolution image of actual events that happened in your life. But then you have agency within those movies. I think you have to be of healthy heart to be able to do it. I think you have to be on a heart rate monitor. It’s not trivial. It’s not like these other psychedelics.
But there’s a wonderful group called Veteran Solutions that has used iboga combined with some other psychedelics in the veterans’ community to great success for things like PTSD. And it’s a group I’ve really tried to support in any way that I can, mainly by being vocal about the great work they’re doing. But you hear incredible stories of people who are just near-cratered in their life or zombied by PTSD and other things post-war, get back a lightness or achieve a lightness and a clarity that they didn’t feel they had.
So I’m very curious about these compounds. The state of Kentucky, we should check this, but I believe it’s taken money from the opioid crisis settlement for ibogaine research. So this is no longer… Yeah, so if you look here, let’s see. Did they do it? Oh, no.
Well, sooner or later we’ll get some happy news up on the internet during this episode.
So that’s good advice coming from… Excellent advice coming from somebody who’s very successful in work and family, so that’s the only thing I can pass along. We hear this from friends of ours as well, but kids are amazing and family’s amazing. All these people who want to be immortal and live to be 200 or something. There’s also the old-fashioned way of having children that live on and evolve a new legacy but they have half your DNA, so that’s exciting.
I actually have a sticky note on my computer just reminding me how good it feels to accomplish some real work, and then I go into it. Right now, it’s the book writing, researching a podcast, and just fight tooth and nail to stay off social media, text message, WhatsApp, YouTube, all that. Get something done.
But even which sponsors. There are dozens of ads now. By the way, that whole Jawzrsizer thing of me saying, “Oh, a guy went from a two to a seven.” I never said that. That’s AI. I would never call a number off somebody. A two to a seven, are you kidding me? It’s crazy. So it’s AI. If you bought the thing, I’m sorry, but our sponsors, we list the sponsors that we have and why on our website, and the decision, do we work with this person or not? Do we still like the product? We’ve got ways with sponsors because of changes in the product. Most of the time, it’s amicable, all good, but just every detail and that just takes a ton of time and energy. But I try and work mostly on content and my team’s constantly trying to keep me out of the other discussions, because I obsess. But yeah, you have to have a team of some sort, someone that you can run things by.
I was down at Jocko’s place not that long ago, and in the evening, did a sauna session with him and some family members of his and some of their friends. And it’s really cool, they all work all day and train all day, and then in the evening, they get together and they sauna and cold plunge. I’m really into this whole thing of gathering with other people at a specific time of day.
I have a gym at my house and Tim will come over and train. We’ve slowed that down in recent months, but I think gathering in groups once a day, being alone for part of the day, it’s very fundamental stuff. We’re not saying anything that hasn’t been said millions of times before, but how often do people actually do that and call the party, be the person to bring people together if it’s not happening? That’s something I’ve really had to learn, even though I’m an introvert, like hey, gather people together.
You came through town the other day and there’s a lot of people at the house. It was rad. Actually, it was funny because I was getting a massage when you walked in. I don’t sit around getting massages very often but I was getting one that day, and then everyone came in and the dog came in and everyone was piled in. It was very sweet.

“Don’t eat with people you wouldn’t starve with.”
The following is a conversation with Andrew Huberman, his fifth time on the podcast. He is the host of the Huberman Lab podcast and is an amazing scientist, teacher, human being, and someone I’m grateful to be able to call a close friend. Also, he has a book coming out next year that you should pre-order now, called Protocols: An Operating Manual for the Human Body. This is the Lex Freeman podcast. To support it, please check out our sponsors in the description. And now, dear friends, here’s Andrew Huberman.
Quitting and evolving
You think there’s ever going to be a day when you walk away from podcasting?
Andrew Huberman
Definitely. I came up within and then on the periphery of skateboard culture. And for the record, I was not a great skateboarder. I always have to say that because skateboarders are relentless if you call something you didn’t do or whatever. I could do a few things and I loved the community and I still have a lot of friends in that community. Jim Thiebaud at Deluxe, you can look him up. He’s the man behind the whole scene. I know Tony Hawk, Danny Way, these guys. I got to see them come up and get big and stay big in many cases, start huge companies like Danny and Colin McKay’s or DC. Some people have a long life in something, some don’t. But one thing I observed and learned a lot from skateboarding at the level of observing the skateboarders and then the ones that started companies, and then what I also observed in science and still observe is you do it for a while, you do it at the highest possible level for you, and then at some point, you pivot and you start supporting the young talent coming in.

In fact, the greatest scientists, people like Richard Axel, Catherine Dulac, there are many other labs in neuroscience, Karl Deisseroth. They’re not just known for doing great science. They’re known for mentoring some of the best scientists that then go on to start their own labs. And I think in podcasting, I am very fortunate I got in a fairly early wave, not the earliest wave, but thanks to your suggestion of doing a podcast, fairly early wave. And I’ll continue to go as long as it feels right, and I feel like I’m doing good in the world and providing good, but I’m already starting to scout talent.
My company that I started with, Rob Moore, SciCom Media, there’s a couple other guys in there too. Mike Blabac, our photographer, Ian Mackey, Chris Ray, Martin Phobes. We are a company that produces podcasts right now. That’s Huberman Lab podcast, but we’re launching a new podcast, Perform with Dr. Andy Galpin.
Lex Fridman
Nice.
Nice.
Andrew Huberman
And we want to do more of that kind of thing, finding a really great talent, highly qualified people, credentialed people. And I’ve got a new kind of obsession with scouring the internet, looking for the young talent in science, in health and related fields. And so will there be a final episode of the HLP? Yeah, I mean, [inaudible 00:03:19] cancer aside someday it’ll be the very last, “And thank you for your interest in science.” And I’ll clip out.

Yeah, I love the idea of walking away and not be dramatic about it. Right? When it feels right, you can leave and you can come back whenever the fuck you want.

John Stewart did this well with the Daily Show. I think that was during the 2016 election when everybody wanted him to stay on and he just walked away. Dave Chappelle for different reasons, walked away.

Gave away so much money, didn’t care, and then came back and was doing stand up in the park in the middle of nowhere. Genius. You have Habib who, undefeated, walks away at the very top of a sport.

[inaudible 00:04:10] or worried. Yeah, I think it’s always a call. The last few years have been tremendous growth. We launched in January, 2021, and even this last year, 2024 has been huge growth in all sorts of ways. It’s been wild. And we have some short form content planned, 30 minute shorter episodes that really distill down the critical elements. We’re also thinking about moving to other venues besides podcasting. So there’s always the thought and the discussion, but when it comes to when to hang up your cleats, it’s like there just comes a natural time where you can do more to mentor the next generation coming in than focusing on self, and so there will come a time for that. And I think it’s critical.

And I think it’s critical.
I mean, again, I saw this in skateboarding like Danny and Colin and Danny’s brother Damon started DC with Ken Block, the driver who unfortunately passed away a little while ago, rally car driver. And they eventually sold it, I think to Quicksilver or something like that. But they’re all phenomenal talents in their respective areas. But they brought in the next line of amazing riders. The plan B thing. Paul Rodriguez for skateboarders, they know who this is now in science, there are scientists like Feynman for instance, I don’t know if anyone can name one of his mentor offspring. So there are scientists who are phenomenal, beyond world-class, multi-generational, world-class, who don’t make good mentors. I’m not saying he wasn’t a good mentor, but that’s not what he’s known for.
And then there are scientists who are known for being excellent scientists and great mentors. And I think there’s no higher celebration to be had at the end of one’s career, if you can look back and be like, “Hey, I’ve put some really important knowledge into the world. People made use of that knowledge.” And guess what? You spawned all these other scientific offspring or sport offspring or podcast offspring. I mean in some ways we look to Rogan and to some of the other earlier podcasters, they paved the way. Rhonda Patrick, first science podcast out there. So eventually the baton passes, but fortunately right now everybody’s active and it feels really good.
Lex Fridman
Yeah. Well, you’re talking about the healthy way to do it, but there’s also a different kind of way where you have somebody like Grisha, Grigori Perelman the mathematician who refused to accept the Fields Medal. So he’s one of the greatest living mathematicians, and he just walked away from mathematics and rejected the Fields Medal.

He’s become essentially a recluse. There’s these photos of him looking very broke, like he could use the money. He turned away the money. He turned away everything. You just have to listen to the inner voice. You have to listen to yourself and make the decisions that don’t make any sense for the rest of the world, and it makes sense to you.

Bob Dylan didn’t show up to pick up his Nobel Peace Prize. That’s punk. Yeah, he probably grew in notoriety for that. Maybe he just doesn’t like going in Sweden, but seemed like it would be a fun trip. I think they do it in a nice time of year, but hey, that’s his right. He earned that right.

I think the best artists aren’t doing it for the prize. They aren’t doing it for the fame or the money. They’re doing it because they love the art.

How to focus and think deeply
Andrew Huberman
That’s the Rick Rubin thing. You got to verb it through, download your inner thing. I don’t think we’ve talked about this, this obsession that I have about how Rick has this way of being very, very still in his body, but keeping his mind very active as a practice. Went and spent some time with him in Italy last June, and we would tread water in his pool in the morning and listen to A History of Rock and Roll in a Hundred Songs. Amazing podcast, by the way.

Lex Fridman
It is.
It is.
Andrew Huberman
And then he would spend a fair amount of time during the day in this kind of meditative state where his mind is very active, body very still. And then Karl Deisseroth, when he came on my podcast, talked about how he forces himself to sit still and think in complete sentences late at night after his kids go to sleep. And there’s a state of mind, rapid eye movement sleep, where your body is completely paralyzed and the mind is extremely active and people credit rapid eye movement sleep with some of the more elaborate emotion-filled dreams and the source of many ideas.

And there are other examples. Einstein, people described him as taking walks around the Princeton campus, then pausing, and would ask him what was going on and the idea that his mind was continuing to churn forward at a higher rate. So this is far from controlled studies, but we’re talking about some incredible minds and creatives who have a practice of stilling the body while keeping the mind deliberately very active, very similar to rapid eye movement sleep. And then there are a lot of people who also report great ideas coming to them in the shower, while running. So it can be the opposite as well, where the body is very active and the mind is perhaps more on kind of like a default mode network, not really focusing on any one specific thing.
Lex Fridman
Interesting. There’s a bunch of physicists and mathematicians I’ve talked to. They talk about sleep deprivation and going crazy hours through the night obsessively pursuing a thing. And then the solution to the problem comes when they finally get rest.

Andrew Huberman
And we know, we just did this sixth episode special series on sleep with Matt Walker, we know that when you deprive yourself of sleep and then you get sleep, you get a rebound in rapid eye movement sleep, you get a higher percentage of rapid eye movement sleep. And Matt talks about this in the podcast and he did an episode on sleep and creativity, sleep and memory and rapid eye movement sleep comes up multiple times in that series. There’s also some very interesting stuff about cannabis withdrawal and rapid eye movement sleep. People who are coming off cannabis often will suffer from insomnia, but when they finally do start sleeping, they dream like crazy. Cannabis is a very controversial topic right now.

Cannabis drama
Lex Fridman
Oh yeah, I saw that. What happened? There’s a bunch of drama around an episode you did on cannabis.
Oh yeah, I saw that. What happened? There’s a bunch of drama around an episode you did on cannabis.
Andrew Huberman
Yeah, we did an episode about cannabis, talked about the health benefits and the potential risks. It’s neither here nor there. It depends on the person, depends on the age, depends on genetic background, a number of other things. We published that episode well over a year ago and it had no issues online, so to speak. And then a clip of it was put to X, where the real action occurs as you know, your favorite [inaudible 00:11:13].

Yeah, the four ounce gloves as opposed to the 16 ounce gloves that is X versus Instagram or YouTube. There was kind of an immediate dog pile from a few people in the cannabis research field.

Andrew Huberman
There were people on our side. There were people not on our side. I mean, the statement that got things riled up the most was this notion that for certain individuals there’s a high potential for inducing psychosis with high THC-containing cannabis. For certain individuals, not all. That sparked some issues. There was really a split. You see this in different fields. There was one person in particular who came out swinging with language that in my opinion is not of the sort that you would use at a university venue, especially among colleagues, but that’s fine. We’re all grownups.

Well, for me, from my perspective, it was strangely rude and it had an air of elitism that to me, was it the source of the problem during Covid that led to the distrust of science and the popularization of disrespecting science because so many scientists spoke with an arrogance and a douchebaggery that I wish we would have a little bit less of.

Andrew Huberman
Yeah, it’s tough because most academics don’t understand that people outside the university system, they’re not familiar with the inner workings of science and the culture. And so you have to be very careful how you present when you’re a university professor. And so he came out swinging, and some four-letter word-type language, and he was obviously upset about it. So I simply said what I would say anywhere, which was, “Hey, look, come on the podcast. Let’s chat, and why don’t you tell me where I’m wrong and let’s discuss.” And fortunately, he agreed. And initially he said, “Well, no, how can I be sure you’re not going to misrepresent me?” And so I said, we got on a DM then an email, then eventually phone call and just said, “Hey, listen, you’re welcome to record the whole conversation. We’ve never done a gotcha on my podcast and let’s just get to the heart of the matter. I think this little controversy is perfect kindling for a really great discussion.”

And he had some other conditions that we worked out and I felt like, “Cool, he’s really interested.” You get a very different person on the phone than you do on Twitter. I will say he’s been very collegial and that conversation is on the schedule. I said, “We’ll fly you out, we’ll put you up.” He said, no, he wants to fly himself. He really wants to make sure that there’s a space between, I think some of the perception of science and health podcasts in the academic community is that it’s all designed to sell something. No, we run ads so it can be free to everyone else.
But I think, look, in the end, he agreed, and I’m excited for the conversation. It was interesting because in the wake of that little exchange, there’s been a bunch of press from traditional press about cannabis has now surpassed alcohol in many cultures within the United States as, when I say cultures, I mean demographics, the United States as the drug of choice. There have been people highlighting the issues of potential psychosis in high THC containing. And so it’s kind interesting to see how traditional media is sort of onboard certain elements that I put forward. And I think there’s some controversy as to whether or not the different strains, the indicas and sativas are biologically different, et cetera. So we’ll get down into the weeds, pun intended, during that one. And I’m excited. It’s the first time that we’ve responded to a direct criticism online about scientific content in a way that really promoted the idea of inviting a particular guest.
And so it’s great. Let’s get a guest on who is an expert in cannabis. I believe, I could be wrong about this, but he’s a behavioral neuroscientist. That’s slightly different training. But look, he seems highly credentialed. It’ll be fun. And we welcome that kind of exchange.
Lex Fridman
I deeply-

And I’m not being diplomatic, I’m just saying it’s cool. He’s coming on. And he was friendly on the phone. He literally came out online and was basically kind of like, “F you. F this and F you.” But you get someone on the phone, it’s like, “Hey, how’s it going?” And they’re like, “Oh, yeah, well.” There was an immediate apology of like, “Hey, listen, I came out. Normally I’m not like that, but online…”

So it’s a little bit like jujitsu, right? People say all sorts of things, I guess. But if you’re like, “All right, well, let’s go,” then it’s probably a different story.

Lex Fridman
It’s not like jujitsu because in jujitsu, people don’t talk shit because they know what the consequences are. Let me just say on mic and off mic, you have been very respectful towards this person, and I look up to you and respect you and admire the fact that you have been. That said, to me, that guy was being a dick. And when you graciously, politely invited him on the podcast, he was still talking down to you the whole time. So I really admire and look forward to listening to you talk to him, but I hope others don’t do that. You are a positive, humble voice exploring all the interesting aspects of science. You want to learn. If you’ve got anything wrong, you want to learn about it. The way he was being a dick, I was just hurt a little bit, not because of him, because there’s some people I really, really admire, brilliant scientists that are not their best selves on Twitter, on X. I don’t understand what happens to their brain.

Well, they regress. They regress. And they also are protected. When you remove the, I mean, no scientific argument should ever come to physical blows, right? But when you remove the real world thing of being right in front of somebody, people will throw all sorts of stones at a distance and over a wall and they’ve got their wife or their husband or their boyfriend or their dog or their cat to go cuddle with them afterwards. But you get in a room and it’s like confrontational people in real life are pretty rare.

But hopefully if they do it, they’re willing to back it up, with knowledge in this case, we’re not talking about physical altercation. He kept coming and he kept putting on conditions, “How do I know you want this?” And I was like, “Well, you can record the conversation.” “How do I know you want that?” “Listen, we’ll pay for you to come out.” “How do you know…?” And eventually he just kind of relented. And to his credit, he’s agreed to come on. I mean, he still has to show up, but once he does, we’ll treat him right, like we would any other guest.
Lex Fridman
Yeah, you treat people really well, and I just hope that people are a little bit nicer on the internet.

Sure. But I can still criticize people for being douchebags, because that’s still not good, inspiring behavior, especially for scientists. That should be sort of symbols of scientific thinking, which requires intellectual humility. Humility is a big part of that, and Twitter is a good place to illustrate that.

Years ago, I was a student in TA, then instructor and then directed a Cold Spring Harbor course on visual neuroscience. These are summer courses that explore different topics. And at night we would host what we hoped were battles in front of the students where you’d get two people on it, would it be neuroprosthetics or molecular tools that would first restore vision to the blind kind of arguments. It’s kind of a silly argument because it’s going to be a combination of both, but you’d get these great arguments. But the arguments were always couched in data. And occasionally you’d get somebody would go like, “Ah,” or would curse or something, but it was the rare, very well-placed insult. It wasn’t coming out swinging.

I think ultimately Twitter’s a record of people’s behavior. The internet is a record of people’s behavior. And here I’m not talking about news reports about people’s behavior. I’m talking about how people show up online is really important. You’ve always carried yourself with a ton of composure and respect, and you would hope that people would grow from that example.
Well, I’ll tell you that the podcasters that I’m scouting, it’s their energy, but it’s also how they treat other people, how they respond to comments. And we’re blessed to have pretty significant reach. When we put out a podcast of someone else’s podcast, it goes far and wide. So like a skateboard team, like a laboratory where you’re selecting people to be in your lab, you want to pick people that you would enjoy working with and that are collegial. Etiquette is lacking nowadays, but you’re in the suit and tie. You’re bringing it back.
Jungian shadow

Bringing it back. You said that your conversation with James Hollis, a Jungian psychoanalyst had a big impact on you. What do you mean?
Bringing it back. You said that your conversation with James Hollis, a Jungian psychoanalyst had a big impact on you. What do you mean?
Andrew Huberman
James Hollis is a 84-year-old Jungian psychoanalyst who’s written 17 books including Under Saturn’s Shadow, which is on the healing and trauma of men, the Eden Project, excuse me, which is about relationships and creating a life. I discovered James Hollis in an online lecture that was recorded I think in San Diego. It’s on YouTube. The audio is terrible, called Creating a Life. And this was somewhere in the 2011 to 2015 span, I can’t remember. And I was on my way to Europe and I called my girlfriend at the time. I was like, “I just found the most incredible lecture I’ve ever heard.” And he talks about the shadow. He talks about your developmental upbringing and how you either align with or go 180 degrees off your parents’ tendencies and values in certain areas. He talked about the specific questions to ask of oneself at different stages of life to live a full life.

So it’s always been a dream of mine to meet him and to record a podcast. And he wasn’t able to travel. So our team went out to DC and sat down with him. We rarely do that nowadays. People come to our studio. And he came in, he had some surgeries recently, and he kind of came in with some assistance from a cane and then sat down and just blew my mind. From start to finish he didn’t miss a syllable. And every sentence that he spoke was like a quotable sentence of with real potency and actionable items. I think one of the things that was most striking to me was how he said, when we take ourselves out of stimulus and response and we just force ourselves to spend some time in the quiet of our thoughts while walking or while seated or while lying down, doesn’t have to be meditation, but it could be, that we access our unconscious mind in ways that reveals to us who we really are and what we really want.
And that if we do that practice repeatedly 10 minutes a day here, 15 minutes a day there, that we start to really touch into our unique gifts and the things that make us each us and the directions we need to take. But that so often we just stay in stimulus response. We just do, do, do, which is great. We have to be productive, but we miss those important messages. And interestingly, he also put forward this idea of what is, it’s like, “Get up, shut up, suit up,” something like that. Get out of bed, suit up and shut up and get to work. He also has that in him, kind of a Goggins type mindset.

Get shit done, but then also dedicate time and stop and just let stuff geyser to the surface from the unconscious mind. And he quotes Shakespeare and he quotes Jung, and he quotes everybody through history with incredible accuracy and in exactly the way needed to drive home a point. But that conversation to me was one that I really felt like, “Okay, if I don’t wake up tomorrow for whatever reason, that one’s in the can and I feel really great about it.” To me, it’s the most important guest recording we’ve ever done in particular because he has wisdom. And while I hope he lives to be 204, chances are he’s got another, what, 20, 30 years with us, hopefully more. But I really, really wanted to capture that information and get it out there. So I’m very, very proud of that one. And he’s the kind of guy that anyone listens to him, young, old, male, female, whatever, and you’re going to get something of value.

What do you think about this idea of the shadow? That the good and the bad that we repress, that hides from plain sight when we analyze ourselves, that’s there, you think there’s an ocean that we don’t have direct access to?

Andrew Huberman
Yes, Jung said it. We have all things inside of us, and we do. And some people are more in touch with those than others, and some people it’s repressed. I mean, does that mean that we could all be horrible people or marvelous people, benevolent people? Perhaps. I think that thankfully more often than not, people lean away from the violent and harmful parts of their shadow. But I think spending time thinking about one’s shadow, shadows is super important. How else are we going to grow? Otherwise, we have these unconscious blind spots of denial or repression or whatever the psychiatrists tell us. But yeah, it clearly exists within all of us. I mean, we have neural circuits for rage. We all do. We have neural circuits for altruism, and no one’s born without these things. In some people they’re atrophied and some people they’re hypertrophied. But I looking inward and recognizing what’s there is key.

I have a lot of new practices around this. I mean, I’m always exploring for protocols. I have to, it’s in my nature. When I went and spent time with Rick, I tried to adopt his practice of staying very still and just letting stuff come to the surface or the Deisserothian way of formulating complete sentences while being still in the body. What I have found works better is what my good friend Tim Armstrong does to write music. He writes music every day. He’s a music producer. He is obviously a singer, guitar player for Rancid, and he’s helped dozens and dozens and dozens of female pop artists and punk rock artists write great songs. And many of the famous songs.

… songs and many of the famous songs that you’ve heard from other artists, Tim helped them write. Tim wakes up sometimes in the middle of the night and what he does is he’ll start drawing or painting. So what he is doing… And Joni Mitchell talks about this too. You find some creative outlet that’s 15 degrees off center from your main creative outlet and you do that thing. So for me, that’s drawing. I like doing anatomical drawings, neuroscience based drawing, drawing neurons, that kind of thing.

I like doing anatomical drawings, neuroscience based drawing, drawing neurons, that kind of thing.
If I do that for a little while, my mind starts churning on the nervous system and biology. And then, I come up with areas I’d like to explore for the podcast, ways I’d like to address certain topics. Right now, I’m very interested in autonomic control. A beautiful paper came out that shows that anyone can learn to control their pupil sizes and without changing luminance through a biofeedback mechanism. That gives them control over their so-called automatic autonomic nervous system. I’ve been looking at what the circuitry is and it’s beautiful.
So I’ll draw the circuitry that we know underlies autonomic function. As I’m doing that, I’m thinking, “Oh, what about autonomic control and those people that supposedly can control their pupil size?” Then you go in and there’s a paper published in Nature Press, one of the nature journals, and there’s a recent paper on this like, “Oh, cool.” And then, we talk about this and then how could this be put into a post or how could this… So doing things that are about 15 degrees off center from your main thing is a great way to access, I believe, the circuits for, in Tim’s case, painting goes to songwriting. I think for Joni Mitchell, that was also the case, right? I think it was drawing and painting to singing and songwriting. For Rick, I don’t know what it is. Maybe it’s listening to podcasts. I don’t know. That’s his business. Do you have anything that you like to focus on that allows you then an easier transition into your main creative work?
Lex Fridman
No, I’d really like to focus on emptiness and silence. So I pick the dragon I have to slay, so whatever the problem I have to work on. And then, just sit there and stare at it.

It’s an empty room, just me and the dragon, and we wait. That’s it. If it’s… Usually, with programming, you’re thinking about a particular design like, “How do I design this thing to solve this problem?”

And then, Mateína Yerba Mate zero sugar, full confession, I helped develop this. I’m a partial owner but I love yerba mate. Half Argentine, been drinking mate since I was a little kid. There’s actually a photo somewhere on the internet when I’m three sitting on my grandfather’s lap, sipping mate out the gourd. And then, this, you might find interesting, this is just a little bit of coffee with a scoop of… Bryan Johnson gave me cocoa, just like pure unsweetened cocoa. So I put that in chocolate. I like it just for the taste. Well, it actually nukes my appetite. Since we’re not going out to dinner tonight until later, I figure that’s good. Yeah. Bryan’s an interesting one, right? He’s really pushing this thing.

Yeah. Although he just hurt his ankle. He posted a photo that he hurt his ankle so now he’s injecting BPC, Body Protection Compound 157, which many, many people are taking by the way. I did an episode on peptides. I should just say, BPC 157, one of the known effects in animal models is angiogenesis like development of new vasculature which can be great in some context. But also, if you have a tumor, you don’t really want to vascularize that tumor anymore. So I worry about people taking BPC 157 continually and there’s very little human data. I think there’s one study and it’s a lousy one, so a lot of animal data.

Some of the peptides are interesting however. There’s one that I’ve experimented with a little bit called Pinealon which I, find even if I’ve just taken it twice a week before sleep, then it times… It seems to do something to the circadian timekeeping mechanism. Because then on other days when I don’t take it, I get unbelievably tired at that time that normally I would do the injection. These are things that I’ll experiment with for a couple of weeks and then typically stop, maybe try something else. But I stay out of things that really stimulate any major hormone pathways when it comes to peptides.
Lex Fridman
That’s actually a really good question of how do you experiment? How long do you try a thing to figure out if it works for you?

Well, I’m very sensitive to these things and I have been doing a lot of things for a long time. So if I add something in, it’s always one thing at a time and I notice right away if it does not make me feel good. There’s a lot of excitement about some of the so-called growth hormone secretagogues: Ipamorelin, Tesamorelin, and Sermorelin. I’ve experimented a little bit with those in the past and they’ve nuked to my rapid eye movement sleep but giving me a lot of deep sleep which doesn’t feel good to me. But other people like them.

I also just generally try and avoid taking peptides that tap into these hormone pathways because you can run into all sorts of issues. But some people take them safely. But usually after about four or five days, I know if I like something or I don’t and then I move on. But I’m not super adventurous with these things. I know people that will take cocktails of peptides with multiple things. They’ll try anything. That’s not me and I do blood work. But also, I’m mainly reading papers and podcasting and I’m teaching a course next spring. In Stanford, I’m going to do a big undergraduate course. So I’m trying to develop that course and things like that. So I don’t need to lift more weight or run further than I already do which is not that much weight or far as it is.

And then, here’s one that I think I brought out for discussion. This is a piece of Nicorette. They’re not a sponsor. Nicotine is an interesting compound. It will raise blood pressure and it is probably not safe for everybody but nicotine is gaining in popularity like crazy. Mainly, these pouches that people put in the lip.

We’re not talking about I’m smoking, vaping, dipping, or snuffing. My interest in nicotine started… This was in 2010, I was visiting Columbia Medical School and I was in the office of the great neurobiologist, Richard Axel. Won the Nobel Prize, co-recipient with Linda Buck, for the discovery of the molecular basis of olfaction. Brilliant guy. He’s probably in his late 70s now.

Yeah. He kept popping Nicorette in his mouth and I was like, “What’s this about?” And he said, “Oh, well…” This was just anecdote but he said this, he said, “Oh. Well, it protects against Parkinson’s and Alzheimer’s.” I said, “It does?” He goes, “Yeah.” I don’t know if he was kidding or not. He’s known for making jokes. And then, he said that when he used to smoke, it really helped his focus in creativity. But then, he quit smoking because he didn’t want lung cancer and he found that he couldn’t focus as well so he would choose Nicorette. So occasionally, like right now, we’ll each… I do a half a piece but I’m not Russian, so I’m a little… Did you just pop the whole thing in your mouth?

I will only allow myself two pieces of Nicorette total per week. You will notice that in the day after you use it, sometimes your throat will feel a little spasm like you might want to cough once or twice. And so, if you’re a singer or you’re a podcaster or something, you have to do long podcasts, you want to just be mindful of it. But yeah, you’re supposed to keep it in your cheek and here we go.

The nucleus basalis is in the basal forebrain. Nucleus has cholinergic neurons that radiate out axons, little wires, that release acetylcholine into the neocortex and elsewhere. When you focus on one particular topic matter or one particular area of your visual field or listening to something and focusing visually, we know that there’s an elaboration of the amount of acetylcholine released there and it binds to nicotinic acetylcholine receptor sites there. So it’s an intentional modulation by acetylcholine. So with nicotine, you’re getting a exogenous or artificial heightening of that circuitry.

Sex life, no disrespect. The major effect of nicotine on the vasculature, my understanding is that it causes vasoconstriction, not vasodilation. Drugs like Cialis, Tadalafil, Viagra, etc., are vasodilators. They allow more blood flow. Nicotine does the opposite, less blood flow to the periphery. But provided dosages are kept low and… I don’t recommend people use it frequently or at all. I don’t recommend young people use it. 25 and younger, brain’s very plastic at that time. Certainly, smoking, dipping, vaping, and snuffing aren’t good because you’re going to run into… They would run into trouble for other reasons. But in any case… Even there, vaping’s a controversial topic. “Probably safer than smoking but has its own issues,” I said something like that and, boy, did I catch a lot of heat for that. You can’t say anything as a health science educator and not piss somebody off. It just depends on where the center of mass is and how far outside that you are.

For me, the caffeine is the main thing. Actually, it’s a really big part of my life. One of the things you recommend, that people wait a bit in the morning to consume caffeine.

If they experience a crash in the afternoon. This is one of the misconceptions. I regret maybe even discussing it. For people that crash in the afternoon, oftentimes, if they delay their caffeine by 60 and 90 minutes in the morning, they will offset some of that. But if you eat a lunch that’s too big or you didn’t sleep well the night before, you’re not going to avoid that afternoon crash. But I’ll wake up sometimes and go straight to hydration and caffeine, especially if going to workout. Here’s a weird one. If I exercise before 8:30 AM especially if I start exercising when I’m a little bit tired, I get energy that lasts all day. If I wait until my peak of energy which is mid-morning, 10:00 AM, 11:00 AM, and I start exercising then, I’m basically exhausted all afternoon. I don’t understand why. I mean, it depends on the intensity of the workout but… So I like to be done, showered, and heading into work by 9:00 AM but I don’t always meet that mark.

So you’re saying it doesn’t affect your energy if you start out with exercising.

Andrew Huberman
I think you can get energy and wake yourself up with exercise if you start early. And then, that fuels you all day long. I think that if you wait until you’re feeling at your best to train, sometimes that’s detrimental. Because then in the afternoon when you’re doing the work we get paid for like research, podcasting, etc., then oftentimes your brain isn’t firing as well.

Math gaffe
Andrew Huberman
Listen to Jocko thing. And then, there’s this phenomenon called entrainment where if you force yourself to exercise or eat or socialize or view bright light at a certain time of day for three to seven days in a row, pretty soon there’s an anticipatory circuit that gets generated. This is why anyone, in theory, can become a morning person to some degree or another. This is also a beautiful example of why you wake up before your alarm clock goes off. People wake up and all of a sudden it goes off, it wasn’t because it clicked. It’s because you have this incredible timekeeping mechanism that exists in sleep. There’s some papers that have been published in the last couple of years, Nature Neuroscience and elsewhere, showing that people can answer math problems in their sleep. Simple math problems but math problems nonetheless. This does not mean that if you ask your partner a question in sleep, that they’re going to answer accurately.

It talks about sperm health, spermatogenesis. It talks about the ovulatory cycle. It talks about things people can do that are considered absolutely supported by science. It talks about some of the things out on the edge a little bit that are a little bit more experimental. It talks about IVF. It talks about ICSI. It talks about all of that. It talks about frequency of pregnancy as a function of age, etc. But there’s this one portion there in the podcast where I’m talking about the probability of a successful pregnancy as a function of age.

It talks about frequency of pregnancy as a function of age, etc. But there’s this one portion there in the podcast where I’m talking about the probability of a successful pregnancy as a function of age.
And so, there was a clip that was cut in which I was describing cumulative probability. By the way, we’ve published cumulative probability histograms in many of my laboratories’ papers, including one that was in Nature Article in 2018. So we run these all the time. Yes, I know the difference between independent and cumulative probability. I do.
The way the clip was cut and what I stated unfortunately combined to a pretty great gaffe where I said, “You’re just adding percentages 20 to 120%.” And then, I made this… Unfortunately, my humor isn’t always so good and I made a joke. I said, “120%, but that’s a different thing altogether.” What I should have said was, “That’s impossible and here’s how it actually works.” But then, it continues where I then describe the cumulative probability histogram for successful pregnancy.
But somewhere in the early portion, I misstated something, right? I made a math error which implied I didn’t understand the difference between independent and cumulative probability which I do. It got picked up and run and people had a really good laugh with that one at my expense. And so, what I did in response to it was rather than just say everything I just said now, I just came out online and said, “Hey folks, in an episode dated this on fertility, I made a math error. Here’s the formula for cumulative probability, successful pregnancy at that age. Here’s the graph. Here’s the…”
I offered it as a teaching moment in two ways. One, for people to understand cumulative probability. It was interesting too, the number of people that had come out critiquing the gaffe. Also, like Balaji and folks came out pointing out that they didn’t understand cumulative probability. So there was a lot of posturing. The dogpile, oftentimes people are quick to dogpile. They didn’t understand but a lot of people did understand. There’s some smart people out there obviously. I called my dad and he was just laughing. He goes, “Oh, this is good. This is like the old school way of hammering academics.”
But the point being, it was a teaching moment. Gave me an opportunity to say, “Hey, I made a mistake.” I also made a mistake in another podcast where I did a micron to millimeter conversion or centimeter conversion. We always correct these in the show note captions. We correct them in the audio now. Unfortunately, on YouTube, it’s harder to correct. You can’t go and edit in segments. We put it in the captions but that was the one teaching moment. If you make a mistake, it’s substantive and relate to data, you apologize and correct the mistake. Use it as a teaching moment.
The other one was to say, “Hey…” In all the thousands of hours of content we’ve put out, I’m sure I’ve made some small errors. I think I once said serotonin when I meant dopamine and you’re going, you’re riffing. It’s a reminder to be careful to edit, double check. But the internet usually edits for us and then we go make corrections.
But it didn’t feel good at first. But ultimately, I can laugh at myself about it. Long ago at Berkeley when I was TA-ing my first class, it was a bio-psychology class. It should be in 1998 or 1999. I was drawing the pituitary gland which has an anterior and a posterior lobe. It actually as a medial lobe too. I had 5, 600 students in that lecture hall. I drew, it was chalkboard and I drew the two lobes of the pituitary and I said… My back was to the audience, I said, “And so, they just hang there,” and everyone just erupted in laughter because it looked like a scrotum with two testicles. I remember thinking like, “Oh my god. I don’t think I can turn around and face this.” I got to turn around sooner or later so I turned around and we just all had a big laugh together. It was embarrassing. I’ll tell you one thing though, they never forgot about the two lobes of the pituitary.
Lex Fridman
Yeah. And you haven’t forgotten about that either.
Yeah. And you haven’t forgotten about that either.
Andrew Huberman
Right. There’s a high salience for these kinds of things. It also was fun to see how excited people get to see people trip. It’s like an elite sprinter trips and does something stupid, like runs the opposite direction out the blocks or something like that and… Or I recall it, one World Cup match years ago, a guy scored against his own team. I think they killed the guy. Do you remember that?

Listen, so there’s some gaffes that get people killed, right? So how forgiving are we for online mistakes? It’s the nature of the mistakes. People were quite gracious about the gaffe and some weren’t. It’s interesting that we, as public health science educators, we’ll do long podcasts sometimes and you need to be really careful. What’s great is AI allows you to check these things now more readily. So that’s cool. There are ways that it’s now going to be more self-correcting. I mean, I think there’s a lot of errors out there on the internet and people are finding them and it’s cool. Things are getting cleaned up.

Sure. I mean, I try and get things right to the best of my ability. I check with experts. It’s interesting. When people really don’t like something that was said in a podcast, a lot of times I chuckle because I’m… At Stanford, we have some amazing scientists but I talk to them people elsewhere and it’s always interesting to me how I’ll get divergent information. And then, I’ll find the overlap in the Venn diagram. I have this question, do I just stay with the overlap in the Venn diagram?

I did an episode on oral health. I didn’t know this until I researched that episode but oral health is critically related to heart health and brain health. That there’s a bacteria that causes cavities, streptococcus, that can make its way into other parts of the body through the mouth that can cause serious issues. There’s the idea that some forms of dementia, some forms of heart disease start in the mouth basically. I talked to no fewer than four dentists, dental experts, and there was a lot of convergence.
I also learned that teeth can demineralize, that’s the formation of cavities. They can also re-mineralize. As long as the cavity isn’t too deep, it can actually fill itself back in, especially if you provide the right substrates for it. That saliva is this incredible fluid that has all this capacity to re-mineralize teeth, provided the milieu is right. Things like alcohol-based mouth washes, killing off some of the critical things you need. It was fascinating and I put out that episode thinking, “Well, I’m not a dentist. I’m not an oral health episode but I talked to a pediatric dentist.” There’s a terrific one, Dr. Downskor Staci, S-T-A-C-I, on Instagram, does great content. Talked to some others.
And then, I just waited for the attack. I was like, “Here we go,” and it didn’t come. Dentists were thanking me. I was like… That’s a rare thing. More often than not, if I do an episode about, say, psilocybin or MDMA, you get some people liking it. Or ADHD and the drugs for ADHD, we did a whole episode on the Ritalin, Vyvanse, Adderall stuff. You get people saying, “Thank you. I prescribed this to my kid and it really helps.” But they’re private about the fact that they do it because they get so much attack from other people. So I like to find the center of mass, report that, try and make it as clear as possible. And then, I know that there’s some stuff where I’m going to catch shit.
What’s frustrating for me is when I see claims that I’m against fluoridization of water. Which I’m not, right? We talked about the benefits of fluoride. It builds hyper strong bonds within the teeth. I went and looked at some of literally the crystal… Excuse me. Not the crystal structure. But essentially, the micron and sub micron structure of teeth is incredible and where fluoride can get in there and form these super strong bonds. You can also form them with things like hydroxyapatite and, “Why is there fluoride in water?” “Well, it’s the best…” Okay. You say some things that are interesting. But then, somehow it gets turned into like you’re against fluoridization which I’m not.
I’ve been accused of being against sunscreen. I wear mineral-based sunscreen on my face. I don’t want to get skin cancer or I use a physical barrier. There is a cohort of people out there that think that all sunscreens are bad. I’m not one of them. I’m not what’s called a sunscreen truther. But then, you get attacked for… So we’re talking about, there are certain sunscreens that are problematic so what… Rhonda Patrick’s now starting to get vocal about this. And so, there are certain topics it’s interesting for which you have to listen carefully to what somebody is saying but there’s a lumper or lumping as opposed to splitting of what health educators say.
And so, it just seems like, like with politics, there’s this urgency to just put people into a camp of expert versus renegade or something. It’s not like that. It’s just not like that. So the short answer is, I really strive, really strive to get things right, but I know that I’m going to piss certain people off. You’ve taught me and Joe’s taught me and other podcasters have taught me. That if you worry too much about it, then you aren’t going to get the newest information out there. Like peptides, there’s very little human data, unless you’re talking about Vyleesi or the Melana… The stuff in the alpha- melanocyte stimulating hormone stuff which are prescribed for female libido to enhance female libido or Sermorelin which is for certain growth hormone deficiencies. With rare exception, there’s very little human data. But people are still super interested and a lot of people are taking and doing these things so you want to get the information out.

Do you try to not just look at the science but research what the various communities are talking about? Like maybe research what the conspiracy theorists are talking about? Just so you know all the armies that are going to be attacking your castle.

Andrew Huberman
Yes. So for instance, there’s a community of people online that believe that if you consume seed oils or something, that you’re setting up your skin sunburn. And if you don’t… There’s all these theories. So I like to know what the theories are. I like to know what the extremes are but I also like to know what the standard conversation is. But there’s generally more agreement than disagreement. I think where I’ve been bullish actually is… Like supplements. People go, “Oh, supplement-“

Andrew Huberman
Kind of bullish actually are supplements. People go, “Oh, supplements.” Well, there’s food supplements, like a protein powder, which is different than a vitamin, and then they are compounds. There are compounds that have real benefit, but people get very nervous about the fact that they’re not regulated, but some of them are vetted for potency and for safety with more rigor than others. And it’s interesting to see how people who take care of themselves and put a lot of work into that are often attacked. That’s been interesting.

And it’s interesting to see how people who take care of themselves and put a lot of work into that are often attacked. That’s been interesting.
Also, one of the most controversial topics nowadays is Ozempic, Mounjaro. I’m very middle-of-the-road on this. I don’t understand why the “health wellness community” is so against these things. I also don’t understand why they have to be looked at as the only route. For some people, they’ve really helped them lose weight, and yes, there can be some muscle loss and other lean body loss, but that can be offset with resistance training. They’ve helped a lot of people. And other people are like, “No, this stuff is terrible.”
I think the most interesting thing about Ozempic, Mounjaro is that they are GLP-1. They’re in the GLP-1 pathway, glucagon-like peptide-1, and it was discovered in Gila monsters, which is a lizard basically, and now the entomologists will dive on me. It’s a big lizard-looking thing that doesn’t eat very often, and they figured out that there’s this peptide that allows it to curb its own appetite at the level of the brain and the gut, and it has a lot of homology to, sequence homology, to what we now call GLP-1.
So I love any time there’s animal biology links to cool human biology links to a drug that’s powerful that can help people with obesity and type 2 diabetes, and there’s evidence they can even curb some addictions. Those are newer data. But I don’t see it as an either/or. In fact, I’ve been a little bit disappointed at the way that the, whatever you want to call it, health wellness, biohacking community has slammed on Ozempic, Mounjaro. They’re like, “Just get out and run and do…”
Listen, there are people who are carrying substantial amounts of weight that running could injure them. They get on these drugs and they can improve, and then hopefully they’re also doing resistance training and eating better, and then you’re bringing all the elements together.
Lex Fridman
Well, why do you think the criticism is happening? Is it that Ozempic became super popular so people are misusing it or that kind of thing?

No, I think what it is that people think if it’s a pharmaceutical, it’s bad, and then or if it’s a supplement, it’s bad depending on which camp they’re in, and wouldn’t it be wonderful to fill in the gap between this divide?
No, I think what it is that people think if it’s a pharmaceutical, it’s bad, and then or if it’s a supplement, it’s bad depending on which camp they’re in, and wouldn’t it be wonderful to fill in the gap between this divide?
What I would like to see in politics and in health is neither right nor left, but what we can just call a league of reasonable people that looks at things on an issue-by-issue basis and fills in the center because I think most people are in the… I don’t want to say center in a political way, but I think most people are reasonable, they want to be reasonable, but that’s not what sells clicks. That’s not what not drives interest.
But I’m a very… I look at issue by issue, person by person. I don’t like ingroup-outgroup stuff. I never have. I’ve got friends from all walks of life. I’ve said this on other podcasts and it always sounds like a political statement, but the push towards polarization, it’s so frustrating. If there’s one thing that’s discouraging to me as I get older each year, I’m like, “Wow, are we ever going to get out of this polarization?”

He did Jay Shetty, he did a few, but when I mean long-form, I mean really long-form, like two, three hours and more relaxed. It was much more orchestrated. Because what happens when the interview is a little bit too short, it becomes into this generic, political type of NBC and CNN type of interview. You get a set of questions and you don’t get to really feel the human, expose the human to the light, and at the full… We talked about the shadow. The good, the bad, and the ugly.

So I think there’s something magical about two, three, four hours, but it doesn’t have to be that long, but it has to have that feeling to it where there’s not people standing around and everybody’s nervous and you’re going to be strictly sticking to the question-and-answer type of feel, but just shooting shit, which Rogan is the best by far in the world at that.
Andrew Huberman
Yeah, he’s… I don’t think people really appreciate how skilled he is at what he does. And the number… I mean, the three or four podcasts per week, plus the UFC announcing, plus comedy tours and stadiums, plus doing comedy shows in the middle of the week, plus a husband and a father and a friend, and jiu-jitsu, the guy’s got superhuman levels of output.

I agree that long-form conversation is a whole other business, and I think that people want and deserve to know the people that are running for office in a different way and to really get to know them. Well, listen, I guess you… I mean, is it clear that he’s going to do jail time or maybe he gets away with a fine?

Here’s one thing that I found really interesting in this whole political landscape. When I’m in Los Angeles, I often get invited to these, they’re not dinners, but gatherings where a local bunch of podcasters will come together, but a lot of people from the entertainment industry, big agencies, big tech, like big, big tech, many of the people have been on this podcast, and they’ll host a discussion or a debate.
And what you find if you look around the room and you talk to people is that about half the people in the room are very left-leaning and very outspoken about that and they’ll tell you exactly who they want to see win the presidential race, and the other half will tell you that they’re for the other side. A lot of people that people assume are on one side of the aisle or the other are in the exact opposite side.
Now, some people are very open about who they’re for, but it’s been very interesting to see how when you get people one-on-one, they’re telling you they want X candidate to win or Y candidate to win, and sometimes I’m like, “Really? I can’t believe it. You?” They’re like, “Yep.”
And so it’s what people think about people’s political leanings is often exactly wrong, and that’s been eyeopening for me. And I’ve seen that in university campuses too. And so it’s going to be really, really interesting to see what happens in November.

In addition to that, as you said, most people are close to the center, despite what Twitter makes it seem like. Most people, whether they’re center-left or center-right, they’re kind of close to the center.

Yeah. I mean, to me the most interesting question, who is going to be the next big candidate in years to come? Who’s that going to be? Right now, I don’t see or know of that person. Who’s it going to be?

Andrew Huberman
Well, that’s the issue, right? Who wants to live in this 12-hour news cycle where you’re just trying to dunk on the other team so that nobody notices the shit that you fucked up? That’s not only not fun or interesting, it also is just like it’s got to be psychosis-inducing at some point.

And I think that God willing, we’re going to… Some young guy or woman is on this and refuses to back down and was just determined to be president and will make it happen, but I don’t even know who the viable candidates are. Maybe you, Lex. You know? We should ask Saagar. Saagar would know.

So to generate the fear VR stimulus for my lab in 20… Was it? Yeah, 2016, we went down to Guadalupe Island off the coast of Mexico. Me and a guy named Michael Muller, who’s a very famous portrait photographer, but also takes photos of sharks. And we used 360 video to build VR of great white sharks. Brought it back to the lab. We published that study in Current Biology.

We published that study in Current Biology.
In 2017, went back down there, and that was the year that I exited the cage. You lower the cage with a crane, and that year, I exited the cage. I had a whole mess with a air failure the day before. I was breathing from a hookah line while in the cage. I had no scuba on. Divers were out. The thing got boa-constricted up and I had an air failure and I had to actually share air and it was a whole mess. A story for another time.
But the next day, because I didn’t want to get PTSD and it was pretty scary, the next day I cage-exited with some other divers. And it turns out with these great white sharks, in Guadalupe, the water’s very clear and you can swim toward them and then they’ll veer off you if you swim toward them. Otherwise, they see you as prey.
Well, in the evening, you’ve brought all the cages up and you’re hopefully all alive. And we were hanging out, fishing for tuna. We had one of the crew on board had a line in the water and was fishing for tuna for dinner, and a shark took the tuna off the line, and it’s a very dramatic take. And you can see the just absolute size of these great white sharks. The waters there are filled with them.
That’s the one. So this video, just the Neuralink link, was shot by Matt MacDougall, who is the head neurosurgeon at Neuralink. There it is. It takes it. Now, believe it or not, it looks like it missed, like it didn’t get the fish. It actually just cut that thing like a band saw. I’m up on the deck with Matt.
Lex Fridman
Whoa.
Whoa.
Andrew Huberman
Yeah. And so when you look at it from the side, you really get a sense of the girth of this fricking thing. So as it comes up, if you-

And they move through the water with such speed. Just a couple… When you’re in the cage and the cage is lowered down below the surface, they’re going around. You’re not allowed to chum the water there. Some people do it. And then when you cage-exit, they’re like, “Well, what are you doing out here?” And then you swim toward them, they veer off.

You’re not allowed to chum the water there. Some people do it. And then when you cage-exit, they’re like, “Well, what are you doing out here?” And then you swim toward them, they veer off.
But what’s interesting is that if you look at how they move through the water, all it takes for one of these great white sharks when it sees a tuna or something it wants to eat, is two flicks of the tail and it becomes like a missile. It’s just unbelievable economy of effort.
And Ocean Ramsey, who is, in my opinion, the greatest of all cage-exit shark divers, this woman who dove with enormous great white sharks, she really understands their behavior, when they’re aggressive, when they’re not going to be aggressive. She and her husband, Juan, I believe his name is, they understand how the tiger sharks differ from the great white sharks.
We were down there basically not understanding any of this. We never should have been there. And actually, the air failure the day before, plus cage-exiting the next day, I told myself after coming up from the cage exit, “That’s it. I’m no longer taking risks with my life. I want to live.” Got back across the border a couple days later, and I was like, “That’s it. I don’t take risks with my life any longer.”
But yeah, MacDougall, Matt MacDougall shot that video and then it went “viral” through Nature is Metal. We passed them that video.
Lex Fridman
Actually, I saw a video where an instructor was explaining how to behave with a shark in the water and that you don’t want to be swimming away because then you’re acting like a prey.

But here we are back to dark stuff again. I like the Shark Attack Map, and the Shark Attack Map shows that Northern California, there were a couple. Actually, a guy’s head got taken off. He was swimming north of San Francisco. There’s been a couple in Northern California. That was really tragic, but most of them are in Florida and Australia.

He’s just… Three members of the party chose to go in. Njai was in this chest-high water, 25 to 50 yards from shore, great white breached the water, seized his head, and that was it.
So it does happen. It’s very infrequent. If you don’t go in the ocean, it’s a very, very, very low probability, but-

I’m thinking the sharks are so agile, they’re amazing. They’ve head-cammed one or body-cammed one moving through the kelp bed, and you look and it’s just they’re so agile moving through the water.

They can hit from all sorts… Oh, and they do this thing. We saw this. You’re out of the cage or in the cage and you’ll look at one and you’ll see it’s eye looking at you. They can’t really foveate, but they’ll look at you, and you’re tracking it and then you’ll look down and you’ll realize that one’s coming at you. They’re ambush predators. They’re working together. It’s fascinating.

That’s the fundamental biological timer. You know, every mammalian species has a short wavelength. So you think like blue, UV type, but absorbing cone, and a longer wavelength absorbing cone. And it does this interesting subtraction to designate when it’s morning and evening because when the sun is low in the sky, you’ve got short-wavelength and long-wavelength light. Like when you look at a sunrise, it’s got blues and yellows, orange and yellows. You look in the evening, reds, orange, and blues, and in the middle of the day, it’s full-spectrum light.

Now, it’s always full-spectrum light, but because of some atmospheric elements and because of the low solar angle, that difference between the different wavelengths of light is the fundamental signal that the neurons in your eye pay attention to and signal to your circadian timekeeping mechanism. At the core of our brain in the suprachiasmatic nucleus, we are wired to be entrained to the rising and setting of the sun. That’s the biological timer, which makes perfect sense because obviously, as the planet spin and revolve-
Lex Fridman
I also wonder how that is affected by, in the rainforest, the sun is not visible often, so you’re under the cover of the trees. So maybe that affects probably psychology.

Well, their social rhythms, their feeding rhythms, sometimes in terms of some species will signal the timing of activity of other species, but yet getting out from the canopy is critical.
Well, their social rhythms, their feeding rhythms, sometimes in terms of some species will signal the timing of activity of other species, but yet getting out from the canopy is critical.
Of course, even under the canopy during the daytime, there’s far more photons than at night. This is always what I’m telling people to get sunlight in their eyes in the morning and in the evening. People say, “There’s no light, no sunlight this time here.” I’m like, “Go outside on a really overcast day. It’s far brighter than it is at night.” So there’s still lots of sunlight, even if you can’t see the sun as an object.
But I love time perception shifts. And you mentioned that in the jungle, it’s linked to the rising and setting of the sun. You also mentioned that on ayahuasca, you zoomed out from the Earth. These are, to me, the most interesting aspects of having a human brain as opposed to another brain. Of course, I’ve only ever had a human brain, which is that you can consciously set your time domain window. We can be focused here, we can be focused on all of Austin, or we can be focused on the entire planet. You can make those choices consciously.
But in the time domain, it’s hard. Different activities bring us into fine-slicing or more broad-bending of time depending on what we’re doing, programming or exercising or researching or podcasting. But just how unbelievably fluid the human brain is in terms of the aperture of the time-space window, of our cognition, and of our experience.
And I feel like this is perhaps one of the more valuable tools that we have access to that we don’t really leverage as much as we should, which is when things are really hard, you need to zoom out and see it as one element within your whole lifespan. And that there’s more to come.
I mean, people commit suicide because they can’t see beyond the time domain they’re in or they think it’s going to go on forever. When we’re happy, we rarely think this is going to last forever, which is an interesting contrast in its own right. But I think that psychedelics, while I have very little experience with them, I have some, and it sounds like they’re just a very interesting window into the different apertures.

Well, how to surf that wave is probably a skill. One of the things I was prepared for and I think is important is not to resist. I think I understand what it means to resist a thing, a powerful wave, and it’s not going to be good. So you have to be able to surf it. So I was ready for that, to relax through it, and maybe because I’m quite good at that from knowing how to relax in all kinds of disciplines, playing piano and guitar when I was super young and then through jiu-jitsu, knowing the value of relaxation and through all kinds of sports, to be able to relax the body fully, just to accept whatever happens to you, that process is probably why it was a very positive experience for me.

Do you have any interest in iboga? I’m very interested in ibogaine and iboga. There’s a colleague of mine and researcher at Stanford, Nolan Williams, who’s been doing some transcranial magnetic stimulation and brain imaging on people who have taken ibogaine.
Do you have any interest in iboga? I’m very interested in ibogaine and iboga. There’s a colleague of mine and researcher at Stanford, Nolan Williams, who’s been doing some transcranial magnetic stimulation and brain imaging on people who have taken ibogaine.
Ibogaine, as I understand it, gives a 22-hour psychedelic journey where no hallucinations with the eyes open, but you close your eyes and you get a very high-resolution image of actual events that happened in your life. But then you have agency within those movies. I think you have to be of healthy heart to be able to do it. I think you have to be on a heart rate monitor. It’s not trivial. It’s not like these other psychedelics.
But there’s a wonderful group called Veteran Solutions that has used iboga combined with some other psychedelics in the veterans’ community to great success for things like PTSD. And it’s a group I’ve really tried to support in any way that I can, mainly by being vocal about the great work they’re doing. But you hear incredible stories of people who are just near-cratered in their life or zombied by PTSD and other things post-war, get back a lightness or achieve a lightness and a clarity that they didn’t feel they had.
So I’m very curious about these compounds. The state of Kentucky, we should check this, but I believe it’s taken money from the opioid crisis settlement for ibogaine research. So this is no longer… Yeah, so if you look here, let’s see. Did they do it? Oh, no.

“Kentucky has some of the highest number of deaths from the opioid…” So they were going to do psychedelic research with ibogaine, supporting research on illegal, folks, psychedelic drug called ibogaine. Well, I guess they backed away from it.

What about seeing different animal species? I’m a huge fan of this guy, Joel Sartore, where he has this photo arc project where he takes portraits of all these different animals. If people aren’t already following him on Instagram, he’s doing some really important work. This guy’s Instagram is amazing.

Well, look at these portraits. The amount of, I don’t want to say personality because we don’t want to project anything onto them, but the eyes, and he’ll occasionally put in a little owl. I delight in things like this. I’ve got some content coming on animals and animal neuroscience and eyes.

Andrew Huberman
All animals. And I’m very interested in kids’ content that incorporates animals, so we have some things brewing there. I could look at this kind of stuff all day long. Look at that bat. Bats, people thinking about bats as little flickering, little annoying disease carrying things, but look how beautiful that little sucker is.

How’s your podcast with the Cookie Monster coming?
How’s your podcast with the Cookie Monster coming?
Andrew Huberman
Oh, yeah. We’ve been in discussions with Cookie. I can’t say too much about that, but Cookie Monster embodies dopamine, right? Cookie Monster wants Cookie, right? Wants Cookie right now. It was that one tweet. “Cookie Monster, I bounce because cookies come from all directions.” It’s just embodying the desire for something, which is an incredible aspect of ourselves. The other one is, do you remember a little while ago, Elmo put out a tweet? “Hey, how’s everyone doing out there?” And it went viral. And the surgeon general of the United States had been talking about the loneliness crisis. He came on the podcast, and a lot of people have been talking about problems with loneliness, mental health issues with loneliness. Elmo puts out a tweet, “Hey, how’s everyone doing out there?” And everyone gravitates towards it. So the different Sesame Street characters really embody the different kinds of aspects of self through very narrow neural circuit perspective. Snuffleupagus is shy and Oscar the Grouch is grouchy, and The Count. “One, two.”

I know you’d like to talk to Vladimir Putin. I’d like to talk to Cookie Monster. It illustrates the differences in our sophistication or something. It illustrates a lot. Yeah, it illustrates a lot.

But yeah, I also love animation. Not anime, that’s not my thing, but animation, so I’m very interested in the use of animation to get science content across. So there are a bunch of things brewing, but anyway, I delight in Sartore’s work and there’s a conservation aspect to it as well, but I think that mostly, I want to thank you for finally putting up something where something’s not being killed or there’s some sad outcome.

Right. One of the reasons I love New York City so much, despite its problems at times, is that everywhere you look, there’s life. It’s like a tropical reef. If you’ve ever done scuba diving or snorkeling, you look on a tropical reef and there’s some little crab working on something, and everywhere you look, there’s life. In the Bay Area, if you go scuba diving or snorkeling, it’s like a kelp bed. The Bay Area is like a kelp bed. Every once in a while, some big fish goes by. It’s like a big IPO, but most of the time, not a whole lot happens. Actually, the Bay Area, it’s interesting as I’ve been going back there more and more recently, there are really cool little subcultures starting to pop up again.

Let’s hope not. You know, before… I mean, I only started doing public facing anything posting on Instagram in 2019, but I used to head up to Gualala on the northern coast of California, sometimes by myself to a little cabin there and spend a weekend by myself and just read and write papers and things like that. I used to do that all the time. I miss that, so some of that. I’m trying to spend a bit more time with my relatives in Argentina, relatives on the East coast, see my parents more. They’re in good health, thankfully. I want to get married and have a family. That’s an important priority. I’m putting a lot of work in there.

And then I’ll listen to it someday and see if I hit the mark? Yeah, well obviously, pick the right partner, but also do the work on yourself. Know yourself. The oracle, know thyself. And I think… Listen, I have a friend – he’s a new friend, but he’s a friend – who I met for a meal. He’s a very, very well known actor overseas and his stuff has made it over here. And we’ve become friends and we went to lunch and we were talking about work and being public facing and all this kind of thing. And then I said, “You have kids, right?” And he says he has four kids. I was like, “Oh yeah, I see your posts with the kids. You seem really happy.” And he just looked at me, he leaned in and he said, “It’s the best gift you’ll ever give yourself.” And he also said, “And pick your partner, the mother of your kids, very carefully.”

So that’s good advice coming from… Excellent advice coming from somebody who’s very successful in work and family, so that’s the only thing I can pass along. We hear this from friends of ours as well, but kids are amazing and family’s amazing. All these people who want to be immortal and live to be 200 or something. There’s also the old-fashioned way of having children that live on and evolve a new legacy but they have half your DNA, so that’s exciting.
Lex Fridman
Yeah, I think you would make an amazing dad.
Yeah, I think you would make an amazing dad.
Andrew Huberman
Thank you.

Andrew Huberman
Right. Well, the chaos of kids is it can either bury you or it can give you energy, but I grew up in a big pack of boys always doing wild and crazy things and so that kind of energy is great. And if it’s not a big pack of wild boys, you have daughters and they can be a different form of chaos. Sometimes, the same form of chaos.

We talk almost every day, three, four times a week, sometimes just briefly, but we’re tight. We really look out for one another. She’s an amazing person, truly an amazing person, and has raised her daughter in an amazing way. My niece is going to head to college in a year or two and my sister’s done an amazing job, and her dad’s done a great job too. They both really put a lot into the family aspect.

I just had Jonathan Haidt on the podcast, the guy who was talking about the anxious generation, coddling the American mind. He’s great. But he was saying that in order to keep kids healthy, they need to not be on social media or have smartphones until they’re 16. I’ve actually been thinking a lot about getting a bunch of friends onto neighboring properties. Everyone talks about this. Not creating a commune or anything like that, but I think Jonathan’s right. We were more or less… Our brain wiring does best when we are raised in small village type environments where kids can forage the whole free-range kids idea. And I grew up skateboarding and building forts and dirt clod wars and all that stuff. It would be so strange to have a childhood without that.

It’s cool to see, for instance, kids in New York City just moving around the city with so much sense of agency. It’s really, really cool. The suburbs where I grew up, as soon as we could get out, take the 7F bus up to San Francisco and hang out with wild ones, while there were dangers, we couldn’t wait to get out of the suburbs. The moment that forts and dirt clod wars and stuff didn’t cut it, we just wanted into the city. So bucket list, I will probably move to a major city, not Los Angeles or San Francisco, in the next few years. New York City potentially.

Yeah. So I’d love to live in New York City for a while. I’ve always wanted to do that and I will do that. I’ve always wanted to also have a place in a very rural area, so Colorado or Montana are high on my list right now, and to be able to pivot back and forth between the two would be great, just for such different experiences. And also, I like a very physical life, so the idea of getting up with the sun in a Montana or a Colorado type environment, and I’ve been putting some effort towards finding a spot for that. And New York City to me, I know it’s got its issues and people say it wasn’t what it was. Okay, I get it, but listen, I’ve never lived there so for me, it’d be entirely new, and Schulz seems full of life.

San Francisco used to be like that. The joke was you have to be naked and on fire in San Francisco before someone takes it, but now, it’s changed. But again, recently I’ve noticed that San Francisco, it’s not just about the skateboarders. There’s some community houses of people in tech that are super interesting. There’s some community housing of people not in tech that I’ve learned about and known people who have lived there, and it’s cool. There’s stuff happening in these cities that’s new and different. That’s what youth is for. They’re supposed to evolve, evolve things out.

So I have a rule for myself that I do a set of tasks for at least five minutes every day, and it turns out that many of them, I do way longer, but just even just doing it, I have to do it every day, and there’s currently 11 of them. It’s just a thing. One of them is playing guitar, for example. Do you do that kind of stuff? Do you do daily habits?

Andrew Huberman
Yeah, I do. I wake up. If I don’t feel I slept enough, I do this non-sleep deep rest yoga nidra thing that I talked about a bunch. We actually released a few of those tracks as audio tracks on Spotify. 10 minute, 20 minute ones. It puts me back into a state that feels like sleep and I feel very rested. Actually, Matt Walker and I are going to run a study. He’s just submitted the IRB to run a study on NSDR and what it’s actually doing to the brain. There’s some evidence of increases in dopamine, et cetera, but those are older studies. Still cool studies, but so I’ll do that, get up, hydrate, and if I’ve got my act together, I punch some caffeine down, like some Mattina, some coffee, maybe another Mattina, and resistance train three days a week, run three days a week and then take one day off, and like to be done by 8:39 and then I want to get into some real work.

I actually have a sticky note on my computer just reminding me how good it feels to accomplish some real work, and then I go into it. Right now, it’s the book writing, researching a podcast, and just fight tooth and nail to stay off social media, text message, WhatsApp, YouTube, all that. Get something done.

How long can you go? Can you go three hours, just deep focus?

That’s tough. For me, I start the day. Actually, that’s why I’m afraid, I’d really prize those morning hours. I start with the work, and I’m trying to hit the four-hour mark of deep focus.

Oh, yeah, the agitation. But I’ve sat across the table from you a couple of years ago when I was out here in Austin doing some work and I was working on stuff, and I noticed you’ll just stare at your notebook sometimes, just pen at the same position and then you’ll get back into it. There are those, building that hydraulic pressure and then go. Yeah, I try and get something done of value, then the communications start, and talking to my podcast producer. My team is everything. The magic potion in the podcast is Rob Moore who has been in the room with me every single solo. Costello used to be in there with us but that’s it. People have asked, journalists have asked, can they sit in? Friends have asked. Nope, just Rob, and for guest interviews, he’s there as well. And I talk to Rob all the time, all the time. We talk multiple times per day, and in life, I’ve made some errors in certain relationship domains in my life in terms of partner choice and things like that, and I certainly don’t blame all of it on them, I’ve played my role. But in terms of picking business partners and friends to work with, Rob is just, it’s been bullseye and Rob has been amazing. Mike Blabac, our photographer, and the guys I mentioned earlier, we just communicate as much as we need to and we pour over every decision like near neuroticism before we put anything out there.

So including even creative decisions of topics to cover, all of that?

Andrew Huberman
Yeah, like a photo for the book jacket the other day, Mike shoots photos, and then we look at them, we pour over them together. A Logo for the Perform podcast with Andy Galpin that we’re launching, like, is that the right contour? Mike, he’s got the aesthetic thing because he was at DC so long as a portrait photographer, and it’s cute, he was close friends with Ken Block who did Gymkhana, all the car jumping in the city stuff. Mike, he’s a true master of that stuff, and we just pour over every little decision.

But even which sponsors. There are dozens of ads now. By the way, that whole Jawzrsizer thing of me saying, “Oh, a guy went from a two to a seven.” I never said that. That’s AI. I would never call a number off somebody. A two to a seven, are you kidding me? It’s crazy. So it’s AI. If you bought the thing, I’m sorry, but our sponsors, we list the sponsors that we have and why on our website, and the decision, do we work with this person or not? Do we still like the product? We’ve got ways with sponsors because of changes in the product. Most of the time, it’s amicable, all good, but just every detail and that just takes a ton of time and energy. But I try and work mostly on content and my team’s constantly trying to keep me out of the other discussions, because I obsess. But yeah, you have to have a team of some sort, someone that you can run things by.
Lex Fridman
For sure, but one of the challenges, the larger the team is, and I’d like to be involved in a lot of different kinds of stuff, including engineering stuff, robotics, work, research, all of those interactions, at least for me, take away from the deep work, the deep focus.

Lex Fridman
Yeah, fundamentally an introvert. So to me, it’s a trade off – getting done versus collaborating, and I have to choose wisely because without collaboration, without a great team, which I’m fortunate enough to be a part of, you wouldn’t get anything really done. But as an individual contributor, to get stuff done, to do the hard work of researching or programming, all that kind of stuff, you need the hours of deep work.

I used to spend a lot more time alone. That’s on my bucket list, spend a bit more time dropped into work alone. I think social media causes our brain to go the other direction. I try and answer some comments and then get back to work.

Andrew Huberman
I use it, so after that morning block, I’ll eat some lunch and I’ll usually do something while I’m doing lunch or something, and then a bit more work and that real work, deep work. And then around 2:30, I do a non-sleep deep rest, take a short nap, wake up, boom, maybe a little more caffeine and then lean into it again. And then I find if you’ve really put in the deep work, two or three bouts per day by about five or 6:00 PM, it’s over.

I was down at Jocko’s place not that long ago, and in the evening, did a sauna session with him and some family members of his and some of their friends. And it’s really cool, they all work all day and train all day, and then in the evening, they get together and they sauna and cold plunge. I’m really into this whole thing of gathering with other people at a specific time of day.
I have a gym at my house and Tim will come over and train. We’ve slowed that down in recent months, but I think gathering in groups once a day, being alone for part of the day, it’s very fundamental stuff. We’re not saying anything that hasn’t been said millions of times before, but how often do people actually do that and call the party, be the person to bring people together if it’s not happening? That’s something I’ve really had to learn, even though I’m an introvert, like hey, gather people together.
You came through town the other day and there’s a lot of people at the house. It was rad. Actually, it was funny because I was getting a massage when you walked in. I don’t sit around getting massages very often but I was getting one that day, and then everyone came in and the dog came in and everyone was piled in. It was very sweet.
Lex Fridman
Again, no devices, but choose wisely the people you gather with.

Lex Fridman
Thank you for clarifying. I wasn’t, which is very weird. Yeah, yeah, the friends you surround yourself with, that’s another thing. I understood that from ayahuasca and from just the experience in the jungle, is just select the people. Just be careful how you allocate your time. I just saw somewhere, Conor McGregor has this good line, I wrote it down, about loyalty. He said, “Don’t eat with people you wouldn’t starve with.” That guy is, he’s big on loyalty. All the shit talk, all of that, set that aside. To me, loyalty is really big, because then if you invest in certain people in your life and they stick by you and you stick by them, what else is life about?

I highly recommend you try it out. Aravind was previously a PhD student at Berkeley, where we long ago first met, and an AI researcher at DeepMind, Google, and finally, OpenAI as a research scientist. This conversation has a lot of fascinating technical details on state-of-the-art, in machine learning, and general innovation in retrieval augmented generation, AKA RAG, chain of thought reasoning, indexing the web, UX design, and much more. This is The Led Fridman Podcast. To support us, please check out our sponsors in the description.
Now, dear friends, here’s Aravind Srinivas. Perplexity is part search engine, part LLM. How does it work, and what role does each part of that the search and the LLM play in serving the final result?
That LLM takes the relevant paragraphs, looks at the query, and comes up with a well-formatted answer with appropriate footnotes to every sentence it says, because it’s been instructed to do so, it’s been instructed with that one particular instruction, given a bunch of links and paragraphs, write a concise answer for the user, with the appropriate citation. The magic is all of this working together in one single orchestrated product, and that’s what we built Perplexity for.
We took this principle and asked ourselves, what is the best way to make chatbots accurate, is force it to only say things that it can find on the internet, and find from multiple sources. This kind of came out of a need rather than, “Oh, let’s try this idea.” When we started the startup, there were so many questions all of us had because we were complete noobs, never built a product before, never built a startup before.
Of course, we had worked on a lot of cool engineering and research problems, but doing something from scratch is the ultimate test. There were lots of questions. What is the health insure? The first employee we hired came and asked us about health insurance. Normal need, I didn’t care. I was like, “Why do I need a health insurance? If this company dies, who cares?” My other two co-founders were married, so they had health insurance to their spouses, but this guy was looking for health insurance, and I didn’t even know anything.
Who are the providers? What is co-insurance, a deductible? None of these made any sense to me. You go to Google. Insurance is a category where, a major ad spend category. Even if you ask for something, Google has no incentive to give you clear answers. They want you to click on all these links and read for yourself, because all these insurance providers are bidding to get your attention.
We integrated a Slack bot that just pings GPT 3.5 and answered a question. Now, sounds like problem solved, except we didn’t even know whether what it said was correct or not. In fact, it was saying incorrect things. We were like, “Okay, how do we address this problem?” We remembered our academic roots. Dennis and myself were both academics. Dennis is my co-founder. We said, “Okay, what is one way we stop ourselves from saying nonsense in a peer reviewed paper?”
We’re always making sure we can cite what it says, what we write, every sentence. Now, what if we ask the chatbot to do that? Then we realized, that’s literally how Wikipedia works. In Wikipedia, if you do a random edit, people expect you to actually have a source for that, and not just any random source. They expect you to make sure that the source is notable. There are so many standards for what counts as notable and not. He decided this is worth working on.
It’s not just a problem that will be solved by a smarter model. There’s so many other things to do on the search layer, and the sources layer, and making sure how well the answer is formatted and presented to the user. That’s why the product exists.
That’s why in the search bar, we say where knowledge begins, because there’s no end to knowledge. You can only expand and grow. That’s the whole concept of The Beginning of Infinity book by David Deutsch. You always seek new knowledge. I see this as sort of a discovery process. Let’s say you literally, whatever you ask me right now, you could have asked Perplexity too. “Hey, Perplexity, is it a search engine, or is it an answer engine, or what is it?” Then you see some questions at the bottom, right?
This is so nice, and it compares Perplexity versus a traditional search engine like Google. Google provides a list of links to websites. Perplexity focuses on providing direct answers and synthesizing information from various sources, user experience, technological approach. There’s an AI integration with Wikipedia-like responses. This is really well done.
For example, if you ask for a stock price, you might even be interested in looking at the historic stock price, even though you never ask for it. You might be interested in today’s price. These are the kind of things that you have to build as custom UIs for every query. Why I think this is a hard problem, it’s not just the next generation model will solve the previous generation models problem’s here. The next generation model will be smarter.
You can do these amazing things like planning, query, breaking it down to pieces, collecting information, aggregating from sources, using different tools. Those kinds of things you can do. You can keep answering harder and harder queries, but there’s still a lot of work to do on the product layer in terms of how the information is best presented to the user, and how you think backwards from what the user really wanted and might want as a next step, and give it to them before they even ask for it.
It’s very hard to make a real difference in just making a better [inaudible 00:15:55] search engine than Google, because they have basically nailed this game for like 20 years. The disruption comes from rethinking the whole UI itself. Why do we need links to be occupying the prominent real estate of the search engine UI? Flip that. In fact, when we first rolled out Perplexity, there was a healthy debate about whether we should still show the link as a side panel or something.
There might be cases where the answer is not good enough, or the answer hallucinates. People are like, “You still have to show the link so that people can still go and click on them and read.” They said no, and that was like, “Okay, then you’re going to have erroneous answers. Sometimes answer is not even the right UI, I might want to explore.” Sure, that’s okay. You still go to Google and do that. We are betting on something that will improve over time.
The models will get better, smarter, cheaper, more efficient. Our index will get fresher, more up to date contents, more detailed snippets, and all of these, the hallucinations will drop exponentially. Of course, there’s still going to be a long tail of hallucinations. You can always find some queries that Perplexity is hallucinating on, but it’ll get harder and harder to find those queries. We made a bet that this technology is going to exponentially improve and get cheaper.
We would rather take a more dramatic position, that the best way to actually make a dent in the search space is to not try to do what Google does, but try to do something they don’t want to do. For them to do this for every single query is a lot of money to be spent, because their search volume is so much higher.
The company is not under any risk, even if the search advertising revenue stops delivering. Let me explain the search advertising revenue for next. The way Google makes money is it has the search engine engine, it’s a great platform. Largest real estate of the internet, where the most traffic is recorded per day, and there are a bunch of AdWords. You can actually go and look at this product called AdWords.google.com, where you get for certain AdWords, what’s the search frequency per word.
You are bidding for your link to be ranked as high as possible for searches related to those AdWords. The amazing thing is any click that you got through that bid, Google tells you that you got it through them. If you get a good ROI in terms of conversions, like what people make more purchases on your site through the Google referral, then you’re going to spend more for bidding against that word. The price for each AdWord is based on a bidding system, an auction system. It’s dynamic. That way, the margins are high.
You came to know about a brand through traditional CPM advertising, there is this view-based advertising, but then you went to Google to actually make the purchase. They still benefit from it. The brand awareness might’ve been created somewhere else, but the actual transaction happens through them because of the click, and therefore, they get to claim that the transaction on your side happened through their referral, and then so you end up having to pay for it.
People overestimate how important it is to make that one brand decision on the shoe. Most of the shoes are pretty good at the top level, and often, you buy based on what your friends are wearing and things like that. Google benefits regardless of how you make your decision.
There are people who literally study this, SEO and SEM, and get a lot of data of so many different user queries from ad blockers and things like that, and then use that to gain their site. Use a specific words. It’s like a whole industry.
You can set out to build a good business and it’s still fine. Maybe the long-term business model of Perplexity can make us profitable in a good company, but never as profitable in a cash cow as Google was. You have to remember that it’s still okay. Most companies don’t even become profitable in their lifetime. Uber only achieved profitability recently. I think the ad unit on Perplexity, whether it exists or doesn’t exist, it’ll look very different from what Google has.
The key thing to remember, though, is there’s this quote in the Art of War, make the weakness of your enemy a strength. What is the weakness of Google is that any ad unit that’s less profitable than a link, or any ad unit that kind of disincentivizes the link click is not in their interest to go aggressive on, because it takes money away from something that’s higher margins. I’ll give you a more relatable example here. Why did Amazon build like the cloud business before Google did?
Even though Google had the greatest distributed systems engineers ever, like Jeff Dean and Sanjay, and built the whole map produce thing, server racks, because cloud was a lower margin business than advertising. There’s literally no reason to go chase something lower margin instead of expanding whatever high margin business you already have. Whereas for Amazon, it’s the flip.
Retail and e-commerce was actually a negative margin business. For them, it’s like a no-brainer to go pursue something that’s actually positive margins and expand it.
They’re a public company. Public companies has all these problems. Similarly, for Perplexity, there’s subscription revenue. We’re not as desperate to go make ad units today. Maybe that’s the best model. Netflix has cracked something there, where there’s a hybrid model of subscription and advertising, and that way, you don’t have to really go and compromise user experience and truthful, accurate answers at the cost of having a sustainable business. The long-term future is unclear, but it’s very interesting.
I think Elon’s also said this publicly, how ads can be useful when done really right. It shouldn’t feel like you even see an ad when you see an ad. That’s truly done right sort of ads. If we figure out something like that, in a way that’s actually disruptive to the link click, then I think it can work.
And in Perplexity, that’s the same thing too. We said the citation thing is pretty cool and domains that get cited a lot, there’s some ranking signal there and that can be used to build a new kind of ranking model for the internet. And that is different from the click-based ranking model that Google’s building. So I think that’s why I admire those guys. They had deep academic grounding, very different from the other founders who are more like undergraduate dropouts trying to do a company. Steve Jobs, Bill Gates, Zuckerberg, they all fit in that mold. Larry and Sergey were the ones who were like Stanford PhDs trying to have this academic roots and yet trying to build a product that people use. And Larry Page just inspired me in many other ways too.
When the products started getting users, I think instead of focusing on going and building a business team, marketing team, the traditional how internet businesses worked at the time, he had the contrarian insight to say, “Hey, search is actually going to be important, so I’m going to go and hire as many PhDs as possible.” And there was this arbitrage that internet bust was happening at the time, and so a lot of PhDs who went and worked at other internet companies were available at not a great market rate. So you could spend less get great talent like Jeff Dean and really focus on building core infrastructure and deeply grounded research. And the obsession about latency, that was, you take it for granted today, but I don’t think that was obvious.
I even read that at the time of launch of Chrome, Larry would test Chrome intentionally on very old versions of Windows on very old laptops and complain that the latency is bad. Obviously, the engineers could say, yeah, you’re testing on some crappy laptop, that’s why it’s happening. But Larry would say, “Hey look, it has to work on a crappy laptop so that on a good laptop, it would work even with the worst internet.” So that’s an insight, I apply it like whenever I’m on a flight, I always that test Perplexity on the flight wifi because flight wifi usually sucks and I want to make sure the app is fast even on that and I benchmark it against ChatGPT or Gemini or any of the other apps and try to make sure that the latency is pretty good.
It’s a very powerful profound thing. It’s very simple but profound if you truly believe in it. You can blame the user for not prompt engineering, right. My mom is not very good at English, so use uses Perplexity and she just comes and tells me the answer is not relevant and I look at her query and I’m like, first instinct is like, “Come on, you didn’t type a proper sentence here.” She’s like, then I realized, okay, is it her fault? The product should understand her intent despite that, and this is a story that Larry says where they just tried to sell Google to Excite and they did a demo to the Excite CEO where they would fire Excite and Google together and type in the same query like university. And then in Google you would rank Stanford, Michigan and stuff, Excite would just have random arbitrary universities. And the Excite CEO would look at it and was like, “That’s because if you typed in this query, it would’ve worked on Excite too.”
But that’s a simple philosophy thing. You just flip that and say, “Whatever the user types, you always supposed to give high quality answers.” Then you build a product for that. You do all the magic behind the scenes so that even if the user was lazy, even if there were typos, even if the speech transcription was wrong, they still got the answer and they love the product. And that forces you to do a lot of things that are currently focused on the user. And also this is where I believe the whole prompt engineering, trying to be a good prompt engineer is not going to be a long-term thing. I think you want to make products work where a user doesn’t even ask for something, but you know that they want it and you give it to them without them even asking for it.
In a product like ours, I don’t know what Google initially used to track. I’ve not studied it, but at least for a product like Perplexity, it’s like number of queries that delighted you. You want to make sure that, I mean, this is literally saying you make the product fast, accurate, and the answers are readable, it’s more likely that users would come back. And of course, the system has to be reliable. A lot of startups have this problem and initially they just do things that don’t scale in the Paul Graham way, but then things start breaking more and more as you scale.
Instead, go and pull that energy into figuring out other problems that we need to solve. So that framework of thinking, that clarity of thought and the operational excellence that he had, update and this is all, your margins, my opportunity, obsession about the customer. Do you know that relentless.com redirects to amazon.com? You want to try it out? It’s a real thing. Relentless.com. He owns the domain. Apparently, that was the first name or among the first names he had for the company.
Distribution, hardest thing in any business is distribution. And I read this Walter Isaacson biography of him. He learned the mistakes that, if you rely on others a lot for your distribution, his first company, Zip2 where he tried to build something like a Google Maps, he ended up, as in, the company ended up making deals with putting their technology on other people’s sites and losing direct relationship with the users because that’s good for your business. You have to make some revenue and people pay you. But then in Tesla, he didn’t do that. He actually didn’t go to dealers or anything. He had, dealt the relationship with the users directly. It’s hard. You might never get the critical mass, but amazingly, he managed to make it happen. So I think that sheer force of will and [inaudible 00:51:37] principles thinking, no work is beneath you, I think that is very important. I’ve heard that in Autopilot he has done data himself just to understand how it works. Every detail could be relevant to you to make a good business decision and he’s phenomenal at that.
It’s just take a lot of terms, policy, gradients. It goes over your head at some point. It’s not that easily accessible. But everyone thought that was the future and that would lead us to AGI in the next few years. And this guy went on the stage in Europe’s, the Premier AI conference and said, “RL is just the cherry on the cake.”
So you can train in parallel instead of backpropagating through time. You can backpropagate through every input token in parallel. So that way you can utilize the GPU computer a lot more efficiently, because you’re just doing Matmos. And so they just said throw away the RNN. And that was powerful. And so then Google Brain, like Vaswani et al that transformer paper identified that, let’s take the good elements of both. Let’s take attention, it’s more powerful than cons. It learns more higher-order dependencies, because it applies more multiplicative compute. And let’s take the insight in WaveNet that you can just have a all convolutional model that fully parallel matrix multiplies and combine the two together and they built a transformer. And that is the, I would say, it’s almost like the last answer. Nothing has changed since 2017 except maybe a few changes on what the nonlinearities are and how the square descaling should be done. Some of that has changed. And then people have tried mixture of experts having more parameters for the same flop and things like that. But the core transformer architecture has not changed.
It wasn’t even called GPT-1, it was just called GPT. Little did they know that it would go on to be this big. But just said, let’s revisit the idea that you can just train a giant language model and it’ll learn natural language common sense, that was not scalable earlier because you were scaling up RNNs, but now you got this new transformer model that’s a 100x more efficient at getting to the same performance. Which means if you run the same job, you would get something that’s way better if you apply the same amount of compute. And so they just trained transformer on all the books like storybooks, children’s storybooks, and that got really good. And then Google took that inside and did BERT, except they did bidirectional, but they trained on Wikipedia and books and that got a lot better.
And then OpenAI followed up and said, okay, great. So it looks like the secret sauce that we were missing was data and throwing more parameters. So we’ll get GPT-2, which is like a billion parameter model, and trained on a lot of links from Reddit. And then that became amazing. Produce all these stories about a unicorn and things like that, if you remember.
So I think that ended up being the breakthrough. It’s not like a attention alone was important. Attention, parallel computation, transformer, scaling it up to do unsupervised pre-training, right data and then constant improvements.
These are all stuff you do in the post-training phase, and that’s what allows you to build products that users can interact with, collect more data, create a flywheel, go and look at all the cases where it’s failing, collect more human annotation on that. I think that’s where a lot more breakthroughs will be made.
But if we do manage to somehow get to a right dataset mix that gives good reasoning skills for a small model, then that’s a breakthrough that disrupts the whole foundation model players, because you no longer need that giant of cluster for training. And if this small model, which has good level of common sense can be applied iteratively, it bootstraps its own reasoning and doesn’t necessarily come up with one output answer, but things for a while bootstraps to calm things for a while. I think that can be truly transformational.
And I think it’s a very interesting way to use natural language explanations as a latent. That way you can refine the model itself to be the reasoner for itself. And you can think of constantly collecting a new data set where you’re going to be bad at trying to arrive at explanations that will help you be good at it, train on it, and then seek more harder data points, train on it. And if this can be done in a way where you can track a metric, you can start with something that’s like say 30% on some math benchmark and get something like 75, 80%. So I think it’s going to be pretty important. And the way it transcends just being good at math or coding is, if getting better at math or getting better at coding translates to greater reasoning abilities on a wider array of tasks outside of two and could enable us to build agents using those kind of models, that’s when I think it’s going to be getting pretty interesting. It’s not clear yet. Nobody’s empirically shown this is the case.
So I feel like even in a world where you call that an AGI, if you feel like you can have a conversation with an AI scientist at the level of Feynman, even in such a world, I don’t think there’s any indication to me that we can mimic Feynman’s curiosity. We could mimic Feynman’s ability to thoroughly research something, and come up with non-trivial answers to something. But can we mimic his natural curiosity about just his period of just being naturally curious about so many different things? And endeavoring to try to understand the right question, or seek explanations for the right question? It’s not clear to me yet.
It’s less about access to a model’s weights, it’s more access to compute that is putting the world in more concentration of power and few individuals. Because not everyone’s going to be able to afford this much amount of compute to answer the hardest questions.
And it doesn’t seem like it’s easy to estimate when it will happen. All we can say for sure is it’s likely to happen at some point. There’s nothing fundamentally impossible about designing system of this nature. And when it happens, it’ll have incredible, incredible impact.
It’s not easy to have this property for most companies don’t have this property. That’s why they’re all struggling to identify where they can use AI. It should be obvious where it should be able to use AI. And there are two products that I feel truly nailed this. One is Google Search, where any improvement in AI, semantic understanding, natural language processing, improves the product and more data makes the embeddings better, things like that. Or self-driving cars where more and more people drive is more data for you and that makes the models better, the vision systems better, the behavior cloning better.
And that’s when we decided, “Okay, how would it look like if we disrupted or created search experiences for things you couldn’t search before?” And we said, “Okay, tables, relational databases. You couldn’t search over them before, but now you can because you can have a model that looks at your question, translates it to some SQL query, runs it against the database. You keep scraping it so that the database is up-to-date and you execute the query, pull up the records and give you the answer.”
But it was suddenly possible with advances like GitHub Copilot. You had code language models that were good. And so we decided we would identify this inside and go again, search over, scrape a lot of data, put it into tables and ask questions.
And then we would do RAG. Given the query, we would pull up templates that were similar-looking template queries and the system would see that build a dynamic few-shot prompt and write a new query for the query you asked and execute it against the database. And many things would still go wrong. Sometimes the SQL would be erroneous. You had to catch errors. It would do like retries. So we built all this into a good search experience over Twitter, which we scraped with academic accounts, this was before Elon took over Twitter. Back then Twitter would allow you to create academic API accounts and we would create lots of them with generating phone numbers, writing research proposals with GPT.
And then we built this demo where you can ask all these sort of questions, stop tweets about AI, like if I wanted to get connected to someone, I’m identifying a mutual follower. And we demoed it to a bunch of people like Yann LeCun, Jeff Dean, Andrej. And they all liked it. Because people like searching about what’s going on about them, about people they are interested in. Fundamental human curiosity, right? And that ended up helping us to recruit good people because nobody took me or my co-founders that seriously. But because we were backed by interesting individuals, at least they were willing to listen to a recruiting pitch.
And it would come up with hilarious things, because back then it would hallucinate a little bit too. So people allowed it. They either were spooked by it saying, “Oh, this AI knows so much about me.” Or they were like, “Oh, look at this AI saying all sorts of shit about me.” And they would just share the screenshots of that query alone. And that would be like, “What is this AI?” “Oh, it’s this thing called Perplexity. And what do you do is you go and type your handle at it and it’ll give you this thing.” And then people started sharing screenshots of that in Discord forums and stuff. And that’s what led to this initial growth when you’re completely irrelevant to at least some amount of relevance.
But we knew that’s like a one-time thing. It’s not like every way is a repetitive query, but at least that gave us the confidence that there is something to pulling up links and summarizing it. And we decided to focus on that. And obviously we knew that this Twitter search thing was not scalable or doable for us because Elon was taking over and he was very particular that he’s going to shut down API access a lot. And so it made sense for us to focus more on regular search.
So for us, the way it worked was we put this out and a lot of people started using it. I thought, “Okay, it’s just a fad and the usage will die.” But people were using it in the time, we put it out on December 7th, 2022, and people were using it even in the Christmas vacation. I thought that was a very powerful signal. Because there’s no need for people when they hang out with their family and chilling on vacation to come use a product by completely unknown startup with an obscure name. So I thought there was some signal there. And okay, we initially didn’t have it conversational. It was just giving only one single query. You type in, you get an answer with summary with the citation. You had to go and type a new query if you wanted to start another query. There was no conversational or suggested questions, none of that. So we launched a conversational version with the suggested questions a week after New Year, and then the usage started growing exponentially.
And most importantly, a lot of people are clicking on the related questions too. So we came up with this vision. Everybody was asking me, “Okay, what is the vision for the company? What’s the mission?” I had nothing. It was just explore cool search products. But then I came up with this mission along with the help of my co-founders that, “Hey, it’s not just about search or answering questions. It’s about knowledge. Helping people discover new things and guiding them towards it, not necessarily giving them the right answer, but guiding them towards it.” And so we said, “We want to be the world’s most knowledge-centric company.” It was actually inspired by Amazon saying they wanted to be the most customer-centric company on the planet. We want to obsess about knowledge and curiosity.
And we felt like that is a mission that’s bigger than competing with Google. You never make your mission or your purpose about someone else because you’re probably aiming low, by the way, if you do that. You want to make your mission or your purpose about something that’s bigger than you and the people you’re working with. And that way you’re thinking completely outside the box too. And Sony made it their mission to put Japan on the map, not Sony on the map.
Wikipedia also in some sense does that. It does organize the information around the world and makes it accessible and useful in a different way. Perplexity does it in a different way, and I’m sure there’ll be another company after us that does it even better than us, and that’s good for the world.
Now, the other place where hallucinations can happen is you have poor snippets, like your index is not good enough. So you retrieve the right documents, but the information in them was not up-to-date, was stale or not detailed enough. And then the model had insufficient information or conflicting information from multiple sources and ended up getting confused.
And the third way it can happen is you added too much detail to the model. Like your index is so detailed, your snippets are so…you use the full version of the page and you threw all of it at the model and asked it to arrive at the answer, and it’s not able to discern clearly what is needed and throws a lot of irrelevant stuff to it and that irrelevant stuff ended up confusing it and made it a bad answer.
The fourth way is you end up retrieving completely irrelevant documents too. But in such a case, if a model is skillful enough, it should just say, “I don’t have enough information.”
So there are multiple dimensions where you can improve a product like this to reduce hallucinations, where you can improve the retrieval, you can improve the quality of the index, the freshness of the pages in the index, and you can include the level of detail in the snippets. You can improve the model’s ability to handle all these documents really well. And if you do all these things well, you can keep making the product better.
So the indexing is fascinating. So is there something you could say about some interesting aspects of how the indexing is done?
And obviously people have robots that text file, and that’s a politeness policy where you should respect the delay time so that you don’t overload their servers by continually crawling them. And then there is stuff that they say is not supposed to be crawled and stuff that they allow to be crawled. And you have to respect that, and the bot needs to be aware of all these things and appropriately crawl stuff.
So that’s the crawling. And then there’s a part of fetching the content from each URL. And once you did that through the headless render, you have to actually build the index now and you have to reprocess, you have to post-process all the content you fetched, which is the raw dump, into something that’s ingestible for a ranking system.
So that requires some machine learning, text extraction. Google has this whole system called Now Boost that extracts the relevant metadata and relevant content from each raw URL content.
And that’s where, when you have billions of pages in your index and you only want the top K, you have to rely on approximate algorithms to get you the top K.
In the LLM, the most important thing is the throughput and the time to first token. We usually refer to it as TTFT, time to first token, and the throughput, which decides how fast you can stream things. Both are really important. And of course, for models that we don’t control in terms of serving, like OpenAI or Anthropic, we are reliant on them to build a good infrastructure. And they are incentivized to make it better for themselves and customers, so that keeps improving. And for models we serve ourselves like Llama-based models, we can work on it ourselves by optimizing at the kernel level. So there, we work closely with NVIDIA, who’s an investor in us, and we collaborate on this framework called TensorRT-LLM. And if needed, we write new kernels, optimize things at the level of making sure the throughput is pretty high without compromising on latency.
And we work on search. I really obsessed about search even before starting Perplexity. My co-founder, Dennis, first job was at Bing. And then my co-founders, Dennis and Johnny, worked at Quora together and they built Quora Digest, which is basically interesting threads every day of knowledge based on your browsing activity. So we were all already obsessed about knowledge and search, so very easy for us to work on this without any immediate dopamine hits because as dopamine hit we get just from seeing search quality improve. If you’re not a person that gets that and you really only get dopamine hits from making money, then it’s hard to work on hard problems. So you need to know what your dopamine system is. Where do you get your dopamine from? Truly understand yourself, and that’s what will give you the founder market or founder product fit.
But what is also true is that with the new power of deeper answers, deeper research, you’re able to ask kind of questions that you couldn’t ask before. Like could you have asked questions like, “Is AWS on Netflix” without an answer box? It’s very hard or clearly explaining the difference between search and answer engines. So that’s going to let you ask a new kind of question, new kind of knowledge dissemination. And I just believe that we are working towards neither search or answer engine but just discovery, knowledge discovery. That’s the bigger mission and that can be catered to through chatbots, answerbots, voice form factor usage, but something bigger than that is guiding people towards discovering things. I think that’s what we want to work on at Perplexity, the fundamental human curiosity.
So I think that sort of impact would be very nice to have. I hope that’s the internet we can create. Through the Pages project we’re working on, we’re letting people create new articles without much human effort. And the insight for that was your browsing session, your query that you asked on Perplexity doesn’t need to be just useful to you. Jensen says this in his thing that, “I do [inaudible 02:37:41] is to ends and I give feedback to one person in front of other people, not because I want to put anyone down or up, but that we can all learn from each other’s experiences.”
Why should it be that only you get to learn from your mistakes? Other people can also learn or another person can also learn from another person’s success. So that was inside that. Okay, why couldn’t you broadcast what you learned from one Q&A session on Perplexity to the rest of the world? So I want more such things. This is just the start of something more where people can create research articles, blog posts, maybe even a small book on a topic. If I have no understanding of search, let’s say, and I wanted to start a search company, it will be amazing to have a tool like this where I can just go and ask, “How does bots work? How do crawls work? What is ranking? What is BM25? In one hour of browsing session, I got knowledge that’s worth one month of me talking to experts. To me, this is bigger than search on internet. It’s about knowledge.
So it is true that there is certain Perplexity sessions where I ask really good questions and I discover really cool things, and that by itself could be a canonical experience that, if shared with others, they could also see the profound insight that I have found.
That’s why I’m saying it’s very important to understand your mission is not about changing the search. Your mission is about making people smarter and delivering knowledge. And the way to do that can start from anywhere. It can start from you reading a page. It can start from you listening to an article-
One of the heartbreaking things for me recently learning more and more is how much bias, human bias, can seep into Wikipedia.
So that’s what we mean about Page where this is not possible with traditional search. You cannot customize the UI. You cannot customize the way the answer is given to you. It’s like a one-size-fits-all solution. That’s why even in our marketing videos we say we are not one-size-fits-all and neither are you. Like you, Lex, would be more detailed and [inaudible 02:46:56] on certain topics, but not on certain others.
So most people, when they advertise new context window increase, they talk a lot about finding the needle in the haystack sort of evaluation metrics and less about whether there’s any degradation in the instruction following performance. So I think that’s where you need to make sure that throwing more information at a model doesn’t actually make it more confused. It’s just having more entropy to deal with now and might even be worse. So I think that’s important. And in terms of what new things it can do, I feel like it can do internal search a lot better. And that’s an area that nobody’s really cracked, like searching over your own files, searching over your Google Drive or Dropbox. And the reason nobody cracked that is because the indexing that you need to build for that is a very different nature than web indexing. And instead, if you can just have the entire thing dumped into your prompt and ask it to find something, it’s probably going to be a lot more capable. And given that the existing solution is already so bad, I think this will feel much better even though it has its issues.
And the other thing that will be possible is memory, though not in the way people are thinking where I’m going to give it all my data and it’s going to remember everything I did, but more that it feels like you don’t have to keep reminding it about yourself. And maybe it will be useful, maybe not so much as advertised, but it’s something that’s on the cards. But when you truly have systems that I think that’s where memory becomes an essential component, where it’s lifelong, it knows when to put it into a separate database or data structure. It knows when to keep it in the prompt. And I like more efficient things, so just systems that know when to take stuff in the prompt and put it somewhere else and retrieve when needed. I think that feels much more an efficient architecture than just constantly keeping increasing the context window. That feels like brute force, to me at least.
And a lot of confusion exists mainly because we just don’t understand things. We just don’t understand a lot of things about other people or about just how the world works. And if our understanding is better, we all are grateful. “Oh wow. I wish I got to that realization sooner. I would’ve made different decisions and my life would’ve been higher quality and better.”
Thank you for listening and hope to see you next time.

They come back and just blow your mind. If we can achieve that, that amount of inference compute, where it leads to a dramatically better answer as you apply more inference compute, I think that will be the beginning of real reasoning breakthroughs.

The following is a conversation with Aravind Srinivas, CEO of Perplexity, a company that aims to revolutionize how we humans get answers to questions on the internet. It combines search and large language models, LLMs, in a way that produces answers where every part of the answer has a citation to human-created sources on the web. This significantly reduces LLM hallucinations, and makes it much easier and more reliable to use for research, and general curiosity-driven late night rabbit hole explorations that I often engage in.

I highly recommend you try it out. Aravind was previously a PhD student at Berkeley, where we long ago first met, and an AI researcher at DeepMind, Google, and finally, OpenAI as a research scientist. This conversation has a lot of fascinating technical details on state-of-the-art, in machine learning, and general innovation in retrieval augmented generation, AKA RAG, chain of thought reasoning, indexing the web, UX design, and much more. This is The Led Fridman Podcast. To support us, please check out our sponsors in the description.
How Perplexity works
Now, dear friends, here’s Aravind Srinivas. Perplexity is part search engine, part LLM. How does it work, and what role does each part of that the search and the LLM play in serving the final result?
Aravind Srinivas
Perplexity is best described as an answer engine. You ask it a question, you get an answer. Except the difference is, all the answers are backed by sources. This is like how an academic writes a paper. Now, that referencing part, the sourcing part is where the search engine part comes in. You combine traditional search, extract results relevant to the query the user asked. You read those links, extract the relevant paragraphs, feed it into an LLM. LLM means large language model.

You combine traditional search, extract results relevant to the query the user asked. You read those links, extract the relevant paragraphs, feed it into an LLM. LLM means large language model.
That LLM takes the relevant paragraphs, looks at the query, and comes up with a well-formatted answer with appropriate footnotes to every sentence it says, because it’s been instructed to do so, it’s been instructed with that one particular instruction, given a bunch of links and paragraphs, write a concise answer for the user, with the appropriate citation. The magic is all of this working together in one single orchestrated product, and that’s what we built Perplexity for.
Lex Fridman
It was explicitly instructed to write like an academic, essentially. You found a bunch of stuff on the internet, and now you generate something coherent, and something that humans will appreciate, and cite the things you found on the internet in the narrative you create for the human?

Aravind Srinivas
Correct. When I wrote my first paper, the senior people who were working with me on the paper told me this one profound thing, which is that every sentence you write in a paper should be backed with a citation, with a citation from another peer reviewed paper, or an experimental result in your own paper. Anything else that you say in the paper is more like an opinion. It’s a very simple statement, but pretty profound in how much it forces you to say things that are only right.

Anything else that you say in the paper is more like an opinion. It’s a very simple statement, but pretty profound in how much it forces you to say things that are only right.
We took this principle and asked ourselves, what is the best way to make chatbots accurate, is force it to only say things that it can find on the internet, and find from multiple sources. This kind of came out of a need rather than, “Oh, let’s try this idea.” When we started the startup, there were so many questions all of us had because we were complete noobs, never built a product before, never built a startup before.
Of course, we had worked on a lot of cool engineering and research problems, but doing something from scratch is the ultimate test. There were lots of questions. What is the health insure? The first employee we hired came and asked us about health insurance. Normal need, I didn’t care. I was like, “Why do I need a health insurance? If this company dies, who cares?” My other two co-founders were married, so they had health insurance to their spouses, but this guy was looking for health insurance, and I didn’t even know anything.
Who are the providers? What is co-insurance, a deductible? None of these made any sense to me. You go to Google. Insurance is a category where, a major ad spend category. Even if you ask for something, Google has no incentive to give you clear answers. They want you to click on all these links and read for yourself, because all these insurance providers are bidding to get your attention.
We integrated a Slack bot that just pings GPT 3.5 and answered a question. Now, sounds like problem solved, except we didn’t even know whether what it said was correct or not. In fact, it was saying incorrect things. We were like, “Okay, how do we address this problem?” We remembered our academic roots. Dennis and myself were both academics. Dennis is my co-founder. We said, “Okay, what is one way we stop ourselves from saying nonsense in a peer reviewed paper?”
We’re always making sure we can cite what it says, what we write, every sentence. Now, what if we ask the chatbot to do that? Then we realized, that’s literally how Wikipedia works. In Wikipedia, if you do a random edit, people expect you to actually have a source for that, and not just any random source. They expect you to make sure that the source is notable. There are so many standards for what counts as notable and not. He decided this is worth working on.
It’s not just a problem that will be solved by a smarter model. There’s so many other things to do on the search layer, and the sources layer, and making sure how well the answer is formatted and presented to the user. That’s why the product exists.

Well, there’s a lot of questions to ask there, but first, zoom out once again. Fundamentally, it’s about search. You said first, there’s a search element, and then there’s a storytelling element via LLM and the citation element, but it’s about search first. You think of Perplexity as a search engine?

I think of Perplexity as a knowledge discovery engine, neither a search engine. Of course, we call it an answer engine, but everything matters here. The journey doesn’t end once you get an answer. In my opinion, the journey begins after you get an answer. You see related questions at the bottom, suggested questions to ask. Why? Because maybe the answer was not good enough, or the answer was good enough, but you probably want to dig deeper and ask more.

That’s why in the search bar, we say where knowledge begins, because there’s no end to knowledge. You can only expand and grow. That’s the whole concept of The Beginning of Infinity book by David Deutsch. You always seek new knowledge. I see this as sort of a discovery process. Let’s say you literally, whatever you ask me right now, you could have asked Perplexity too. “Hey, Perplexity, is it a search engine, or is it an answer engine, or what is it?” Then you see some questions at the bottom, right?

Is Perplexity a search engine or an answer engine? That’s a poorly phrased question, but one of the things I love about Perplexity, the poorly phrased questions will nevertheless lead to interesting directions. Perplexity is primarily described as an answer engine rather than a traditional search engine. Key points showing the difference between answer engine versus search engine.

This is so nice, and it compares Perplexity versus a traditional search engine like Google. Google provides a list of links to websites. Perplexity focuses on providing direct answers and synthesizing information from various sources, user experience, technological approach. There’s an AI integration with Wikipedia-like responses. This is really well done.

Exactly, because that’s not just about throwing an LLM. When you’re asking, “Oh, what dress should I wear out today in Austin?” You do want to get the weather across the time of the day, even though you didn’t ask for it. The Google presents this information in cool widgets, and I think that is where this is a very different problem from just building another chat bot. The information needs to be presented well, and the user intent.

The Google presents this information in cool widgets, and I think that is where this is a very different problem from just building another chat bot. The information needs to be presented well, and the user intent.
For example, if you ask for a stock price, you might even be interested in looking at the historic stock price, even though you never ask for it. You might be interested in today’s price. These are the kind of things that you have to build as custom UIs for every query. Why I think this is a hard problem, it’s not just the next generation model will solve the previous generation models problem’s here. The next generation model will be smarter.
You can do these amazing things like planning, query, breaking it down to pieces, collecting information, aggregating from sources, using different tools. Those kinds of things you can do. You can keep answering harder and harder queries, but there’s still a lot of work to do on the product layer in terms of how the information is best presented to the user, and how you think backwards from what the user really wanted and might want as a next step, and give it to them before they even ask for it.
Lex Fridman
I don’t know how much of that is a UI problem of designing custom UIs for a specific set of questions. I think at the end of the day, Wikipedia looking UI is good enough if the raw content that’s provided, the text content, is powerful. If I want to know the weather in Austin, if it gives me five little pieces of information around that, maybe the weather today and maybe other links to say, “Do you want hourly?” Maybe it gives a little extra information about rain and temperature, all that kind of stuff.

Yeah, exactly, but you would like the product, when you ask for weather, let’s say it localizes you to Austin automatically, and not just tell you it’s hot, not just tell you it’s humid, but also tells you what to wear. You wouldn’t ask for what to wear, but it would be amazing if the product came and told you what to wear.

A lot more, definitely. Personalization, there’s an 80/20 here. The 80/20 is achieved with your location, let’s say your gender, and then sites you typically go to, like rough sense of topics of what you’re interested in. All that can already give you a great personalized experience. It doesn’t have to have infinite memory, infinite context windows, have access to every single activity you’ve done. That’s an overkill.

Right, but then that starts to get into details, really, I’d never ask night with the weather because I don’t care. Usually, it’s always going to be about running, and even at night, it’s going to be about running, because I love running at night. Let me zoom out, once again, ask a similar I guess question that we just asked Perplexity. Can you, can Perplexity take on and beat Google or Bing in search?

We do not have to beat them, neither do we have to take them on. In fact, I feel the primary difference of Perplexity from other startups that have explicitly laid out that they’re taking on Google is that we never even tried to play Google at their own game. If you’re just trying to take on Google by building another [inaudible 00:15:38] search engine and with some other differentiation, which could be privacy, or no ads, or something like that, it’s not enough.

If you’re just trying to take on Google by building another [inaudible 00:15:38] search engine and with some other differentiation, which could be privacy, or no ads, or something like that, it’s not enough.
It’s very hard to make a real difference in just making a better [inaudible 00:15:55] search engine than Google, because they have basically nailed this game for like 20 years. The disruption comes from rethinking the whole UI itself. Why do we need links to be occupying the prominent real estate of the search engine UI? Flip that. In fact, when we first rolled out Perplexity, there was a healthy debate about whether we should still show the link as a side panel or something.
There might be cases where the answer is not good enough, or the answer hallucinates. People are like, “You still have to show the link so that people can still go and click on them and read.” They said no, and that was like, “Okay, then you’re going to have erroneous answers. Sometimes answer is not even the right UI, I might want to explore.” Sure, that’s okay. You still go to Google and do that. We are betting on something that will improve over time.
The models will get better, smarter, cheaper, more efficient. Our index will get fresher, more up to date contents, more detailed snippets, and all of these, the hallucinations will drop exponentially. Of course, there’s still going to be a long tail of hallucinations. You can always find some queries that Perplexity is hallucinating on, but it’ll get harder and harder to find those queries. We made a bet that this technology is going to exponentially improve and get cheaper.
We would rather take a more dramatic position, that the best way to actually make a dent in the search space is to not try to do what Google does, but try to do something they don’t want to do. For them to do this for every single query is a lot of money to be spent, because their search volume is so much higher.
Lex Fridman
Let’s maybe talk about the business model of Google. One of the biggest ways they make money is by showing ads as part of the 10 links. Can you maybe explain your understanding of that business model and why that doesn’t work for Perplexity?

Aravind Srinivas
Yeah. Before I explain the Google AdWords model, let me start with a caveat that the company Google, or called Alphabet, makes money from so many other things. Just because the ad model is under risk doesn’t mean the company’s under risk. For example, Sundar announced that Google Cloud and YouTube together are on a $100 billion annual recurring rate right now. That alone should qualify Google as a trillion-dollar company if you use a 10X multiplier and all that.

That alone should qualify Google as a trillion-dollar company if you use a 10X multiplier and all that.
The company is not under any risk, even if the search advertising revenue stops delivering. Let me explain the search advertising revenue for next. The way Google makes money is it has the search engine engine, it’s a great platform. Largest real estate of the internet, where the most traffic is recorded per day, and there are a bunch of AdWords. You can actually go and look at this product called AdWords.google.com, where you get for certain AdWords, what’s the search frequency per word.
You are bidding for your link to be ranked as high as possible for searches related to those AdWords. The amazing thing is any click that you got through that bid, Google tells you that you got it through them. If you get a good ROI in terms of conversions, like what people make more purchases on your site through the Google referral, then you’re going to spend more for bidding against that word. The price for each AdWord is based on a bidding system, an auction system. It’s dynamic. That way, the margins are high.

Actually, to be very fair, this model was first conceived by Overture. Google innovated a small change in the bidding system, which made it even more mathematically robust. We can go into details later, but the main part is that they identified a great idea being done by somebody else, and really mapped it well onto a search platform that was continually growing. The amazing thing is they benefit from all other advertising done on the internet everywhere else.

You came to know about a brand through traditional CPM advertising, there is this view-based advertising, but then you went to Google to actually make the purchase. They still benefit from it. The brand awareness might’ve been created somewhere else, but the actual transaction happens through them because of the click, and therefore, they get to claim that the transaction on your side happened through their referral, and then so you end up having to pay for it.
Lex Fridman
I’m sure there’s also a lot of interesting details about how to make that product great. For example, when I look at the sponsored links that Google provides, I’m not seeing crappy stuff. I’m seeing good sponsor. I actually often click on it, because it’s usually a really good link, and I don’t have this dirty feeling like I’m clicking on a sponsor. Usually in other places, I would have that feeling, like a sponsor’s trying to trick me into it.

There’s a reason for that. Let’s say you’re typing shoes and you see the ads, it’s usually the good brands that are showing up as sponsored, but it’s also because the good brands are the ones who have a lot of money, and they pay the most for a corresponding AdWord. It’s more a competition between those brands, like Nike, Adidas, Allbirds, Brooks, Under Armor, all competing with each other for that AdWord.

People overestimate how important it is to make that one brand decision on the shoe. Most of the shoes are pretty good at the top level, and often, you buy based on what your friends are wearing and things like that. Google benefits regardless of how you make your decision.

There are ways that Google prevents that by tracking in general how many visits you get, and also making sure that if you don’t actually rank high on regular search results, but you’re just paying for the cost per click, then you can be down voted. There are many signals. It’s not just one number, I pay super high for that word and I just can the results, but it can happen if you’re pretty systematic.

Yeah, it’s a whole industry, and parts of that industry that’s very data-driven, which is where Google sits is the part that I admire. A lot of parts that industry is not data-driven, more traditional. Even podcast advertisements, they’re not very data-driven, which I really don’t like. I admire Google’s innovation in AdSense that to make it really data-driven, make it so that the ads are not distracting to the user experience, that they’re a part of the user experience, and make it enjoyable to the degree that ads can be enjoyable.

There’s this giant flow of queries that’s happening, and you have to serve all of those links. You have to connect all the pages that have been indexed, and you have to integrate somehow the ads in there, and showing the things that the ads are shown in a way that maximizes the likelihood that they click on it, but also minimize the chance that they get pissed off from the experience. All of that, that’s a fascinating gigantic system.

Yeah, so Perplexity makes answer the first party characteristic of the site, instead of links. The traditional ad unit on a link doesn’t need to apply at Perplexity. Maybe that’s not a great idea. Maybe the ad unit on a link might be the highest margin business model ever invented, but you also need to remember that for a new business that’s trying to create, for a new company that’s trying to build its own sustainable business, you don’t need to set out to build the greatest business of mankind.

You can set out to build a good business and it’s still fine. Maybe the long-term business model of Perplexity can make us profitable in a good company, but never as profitable in a cash cow as Google was. You have to remember that it’s still okay. Most companies don’t even become profitable in their lifetime. Uber only achieved profitability recently. I think the ad unit on Perplexity, whether it exists or doesn’t exist, it’ll look very different from what Google has.
The key thing to remember, though, is there’s this quote in the Art of War, make the weakness of your enemy a strength. What is the weakness of Google is that any ad unit that’s less profitable than a link, or any ad unit that kind of disincentivizes the link click is not in their interest to go aggressive on, because it takes money away from something that’s higher margins. I’ll give you a more relatable example here. Why did Amazon build like the cloud business before Google did?
Even though Google had the greatest distributed systems engineers ever, like Jeff Dean and Sanjay, and built the whole map produce thing, server racks, because cloud was a lower margin business than advertising. There’s literally no reason to go chase something lower margin instead of expanding whatever high margin business you already have. Whereas for Amazon, it’s the flip.
Retail and e-commerce was actually a negative margin business. For them, it’s like a no-brainer to go pursue something that’s actually positive margins and expand it.

Your margin is my opportunity. Whose quote is that, by the way? Jeff Bezos. He applies it everywhere. He applied it to Walmart and physical brick and mortar stores, because they already have, it’s a low margin business. Retail is an extremely low margin business. By being aggressive in one-day delivery, two-day delivery rates, burning money, he got market share and e-commerce, and he did the same thing in cloud.

Right now, yes, but that doesn’t mean it’s the end of the world for them. That’s why this is a very interesting game. No, there’s not going to be one major loser or anything like that. People always like to understand the world as zero-sum games. This is a very complex game, and it may not be zero-sum at all, in the sense that the more and more the business that the revenue of cloud and YouTube grows, the less is the reliance on advertisement revenue. Though the margins are lower there, so it’s still a problem.

They’re a public company. Public companies has all these problems. Similarly, for Perplexity, there’s subscription revenue. We’re not as desperate to go make ad units today. Maybe that’s the best model. Netflix has cracked something there, where there’s a hybrid model of subscription and advertising, and that way, you don’t have to really go and compromise user experience and truthful, accurate answers at the cost of having a sustainable business. The long-term future is unclear, but it’s very interesting.
Lex Fridman
Do you think there’s a way to integrate ads into Perplexity that that works on all fronts? It doesn’t interfere with the quest of seeking truth, it doesn’t interfere with the user experience of getting an academic article style output on a question? They asked all of this.

It’s possible, and many experiments need to be tried. The trick is to really figure out how to do it in a way that doesn’t make users lose trust in your product, and yet build something that can connect people with the right source of information. I kind of like how Instagram does its ads, for example. It’s really targeted at relevance and it almost doesn’t look like you’re seeing an ad.

I think Elon’s also said this publicly, how ads can be useful when done really right. It shouldn’t feel like you even see an ad when you see an ad. That’s truly done right sort of ads. If we figure out something like that, in a way that’s actually disruptive to the link click, then I think it can work.
Lex Fridman
Well, there’s also other ways that people can mess with the output of Perplexity, just like there’s super aggressive attacks on Google through SEO, where people try to do search engine optimization, like scammy websites, they’re probably trying to game the system. There’s probably ways to do that with Perplexity.

Lex Fridman
Yeah, it’s an interesting game. It’s really, really interesting game. I read that you looked up to Larry Page and Sergey Brin and that you can recite passages from In The Plex and that book was very influential to you and How Google Works was influential. So what do you find inspiring about Google, about those two guys, Larry Page and Sergey Brin and just all the things they were able to do in the early days of the internet?

First of all, the number one thing I took away, there’s not a lot of people talk about this is, they didn’t compete with the other search engines by doing the same thing. They flipped it like they said, “Hey, everyone’s just focusing on text-based similarity, traditional information extraction and information retrieval, which was not working that great. What if we instead ignore the text? We use the text at a basic level, but we actually look at the link structure and try to extract ranking signal from that instead.” I think that was a key insight.

Lex Fridman
Page rank was just a genius flipping of the table.
Page rank was just a genius flipping of the table.
Aravind Srinivas
Page rank, yeah. Exactly. And the fact, I mean, Sergey’s Magic came like he just reduced it to power iteration and Larry’s idea was, the link structure has some valuable signal. So look, after that, they hired a lot of grade engineers who and came and built more ranking signals from traditional information extraction that made page rank less important. But the way they got their differentiation from other search engines at the time was through a different ranking signal and the fact that it was inspired from academic citation graphs, which coincidentally was also the inspiration for us in Perplexity, citations. You are an academic, you’ve written papers. We all have Google scholars, we all, at least first few papers we wrote, we’d go and look at Google’s scholar every single day and see if the citation is increasing. There was some dopamine hit from that, right. So papers that got highly cited was usually a good thing, good signal.

There was some dopamine hit from that, right. So papers that got highly cited was usually a good thing, good signal.
And in Perplexity, that’s the same thing too. We said the citation thing is pretty cool and domains that get cited a lot, there’s some ranking signal there and that can be used to build a new kind of ranking model for the internet. And that is different from the click-based ranking model that Google’s building. So I think that’s why I admire those guys. They had deep academic grounding, very different from the other founders who are more like undergraduate dropouts trying to do a company. Steve Jobs, Bill Gates, Zuckerberg, they all fit in that mold. Larry and Sergey were the ones who were like Stanford PhDs trying to have this academic roots and yet trying to build a product that people use. And Larry Page just inspired me in many other ways too.
When the products started getting users, I think instead of focusing on going and building a business team, marketing team, the traditional how internet businesses worked at the time, he had the contrarian insight to say, “Hey, search is actually going to be important, so I’m going to go and hire as many PhDs as possible.” And there was this arbitrage that internet bust was happening at the time, and so a lot of PhDs who went and worked at other internet companies were available at not a great market rate. So you could spend less get great talent like Jeff Dean and really focus on building core infrastructure and deeply grounded research. And the obsession about latency, that was, you take it for granted today, but I don’t think that was obvious.
I even read that at the time of launch of Chrome, Larry would test Chrome intentionally on very old versions of Windows on very old laptops and complain that the latency is bad. Obviously, the engineers could say, yeah, you’re testing on some crappy laptop, that’s why it’s happening. But Larry would say, “Hey look, it has to work on a crappy laptop so that on a good laptop, it would work even with the worst internet.” So that’s an insight, I apply it like whenever I’m on a flight, I always that test Perplexity on the flight wifi because flight wifi usually sucks and I want to make sure the app is fast even on that and I benchmark it against ChatGPT or Gemini or any of the other apps and try to make sure that the latency is pretty good.
Lex Fridman
It’s funny, I do think it’s a gigantic part of a success of a software product is the latency.

That’s an engineering challenge, but when it’s done right, obsessively reducing latency, you actually have, there’s a face shift in the user experience where you’re like, holy, this becomes addicting and the amount of times you’re frustrated goes quickly to zero.

And every detail matters like, on the search bar, you could make the user go to the search bar and click to start typing a query or you could already have the cursor ready and so that they can just start typing. Every minute detail matters and auto scroll to the bottom of the answer instead of forcing them to scroll. Or like in the mobile app when you’re clicking, when you’re touching the search bar, the speed at which the keypad appears, we focus on all these details, we track all these latencies and that’s a discipline that came to us because we really admired Google. And the final philosophy I take from Larry, I want to highlight here is, there’s this philosophy called the user is never wrong.

And the final philosophy I take from Larry, I want to highlight here is, there’s this philosophy called the user is never wrong.
It’s a very powerful profound thing. It’s very simple but profound if you truly believe in it. You can blame the user for not prompt engineering, right. My mom is not very good at English, so use uses Perplexity and she just comes and tells me the answer is not relevant and I look at her query and I’m like, first instinct is like, “Come on, you didn’t type a proper sentence here.” She’s like, then I realized, okay, is it her fault? The product should understand her intent despite that, and this is a story that Larry says where they just tried to sell Google to Excite and they did a demo to the Excite CEO where they would fire Excite and Google together and type in the same query like university. And then in Google you would rank Stanford, Michigan and stuff, Excite would just have random arbitrary universities. And the Excite CEO would look at it and was like, “That’s because if you typed in this query, it would’ve worked on Excite too.”
But that’s a simple philosophy thing. You just flip that and say, “Whatever the user types, you always supposed to give high quality answers.” Then you build a product for that. You do all the magic behind the scenes so that even if the user was lazy, even if there were typos, even if the speech transcription was wrong, they still got the answer and they love the product. And that forces you to do a lot of things that are currently focused on the user. And also this is where I believe the whole prompt engineering, trying to be a good prompt engineer is not going to be a long-term thing. I think you want to make products work where a user doesn’t even ask for something, but you know that they want it and you give it to them without them even asking for it.
Lex Fridman
One of the things that Perplexity is clearly really good at is figuring out what I meant from a poorly constructed query.

Aravind Srinivas
Yes. And I don’t even need you to type in a query. You can just type in a bunch of words, it should be okay. That’s the extent to which you got to design the product. Because people are lazy and a better product should be one that allows you to be more lazy, not less. Sure there is some, the other side of the argument is to say, “If you ask people to type in clearer sentences, it forces them to think.” And that’s a good thing too. But at the end, products need to be having some magic to them and the magic comes from letting you be more lazy.

Exactly. That was one of the most insightful experiments we did after we launched, we had our designers and co-founders were talking and then we said, “Hey, the biggest enemy to us is not Google. It is the fact that people are not naturally good at asking questions.” Why is everyone not able to do podcasts like you? There is a skill to asking good questions, and everyone’s curious though. Curiosity is unbounded in this world. Every person in the world is curious, but not all of them are blessed to translate that curiosity into a well-articulated question. There’s a lot of human thought that goes into refining your curiosity into a question, and then there’s a lot of skill into making sure the question is well-prompted enough for these AIs.

And then there’s little design decisions like for me, I’m a keyboard guy, so the Ctrl-I to open a new thread, which is what I use, it speeds me up a lot, but the decision to show the shortcut in the main Perplexity interface on the desktop is pretty gutsy. That’s probably, as you get bigger and bigger, there’ll be a debate, but I like it. But then there’s different groups of humans.

Exactly. I mean, some people, I’ve talked to Karpathy about this. He uses our product. He hits the sidekick, the side panel. He just wants it to be auto hidden all the time. And I think that’s good feedback too, because the mind hates clutter. When you go into someone’s house, you want it to be, you always love it when it’s well maintained and clean and minimal. There’s this whole photo of Steve Jobs in this house where it’s just a lamp and him sitting on the floor. I always have that vision when designing Perplexity to be as minimal as possible. Google was also, the original Google was designed like that. There’s just literally the logo and the search bar and nothing else.

I mean, there’s pros and cons to that. I would say in the early days of using a product, there’s a anxiety when it’s too simple because you feel like you don’t know the full set of features, you don’t know what to do.

Yeah, that’s the hard part. When you’re growing, when you’re trying to grow the user base but also retain your existing users, making sure you’re not, how do you balance the trade-offs? There’s an interesting case study of this notes app and they just kept on building features for their power users and then what ended up happening is the new users just couldn’t understand the product at all. And there’s a whole talk by a Facebook, early Facebook data science person who was in charge of their growth that said the more features they shipped for the new user than existing user, it felt like that, that was more critical to their growth. And you can just debate all day about this, and this is why product design and growth is not easy.

Yeah. One of the biggest challenges for me is the simple fact that people that are frustrated are the people who are confused. You don’t get that signal or the signal is very weak because they’ll try it and they’ll leave and you don’t know what happened. It’s like the silent, frustrated majority.

Aravind Srinivas
Right. Every product figured out likes one magic not metric that is pretty well correlated with whether that new silent visitor will likely come back to the product and try it out again. For Facebook, it was like the number of initial friends you already had outside Facebook that were on Facebook when you joined, that meant more likely that you were going to stay. And for Uber it’s like number of successful rides you had.

In a product like ours, I don’t know what Google initially used to track. I’ve not studied it, but at least for a product like Perplexity, it’s like number of queries that delighted you. You want to make sure that, I mean, this is literally saying you make the product fast, accurate, and the answers are readable, it’s more likely that users would come back. And of course, the system has to be reliable. A lot of startups have this problem and initially they just do things that don’t scale in the Paul Graham way, but then things start breaking more and more as you scale.

One thing I’ve done is take parts from every person. And so, it’ll almost be like an ensemble algorithm over them. So I’d probably keep the answer short and say each person what I took. With Bezos, I think it’s the forcing [inaudible 00:47:21] to have real clarity of thought. And I don’t really try to write a lot of docs. There’s, when you’re a startup, you have to do more in actions and [inaudible 00:47:33] docs, but at least try to write some strategy doc once in a while just for the purpose of you gaining clarity, not to have the doc shared around and feel like you did some work.

Just even like next six months, what are we doing? Why are we doing what we’re doing? What is the positioning? And I think also, the fact that meetings can be more efficient if you really know what you want out of it. What is the decision to be made? The one-way door or two-way door things. Example, you’re trying to hire somebody. Everyone’s debating, “Compensation is too high. Should we really pay this person this much?” And you are like, “Okay, what’s the worst thing that’s going to happen if this person comes and knocks it out of the door for us? You wouldn’t regret paying them this much.” And if it wasn’t the case, then it wouldn’t have been a good fit and we would pack hard ways. It’s not that complicated. Don’t put all your brain power into trying to optimize for that 20, 30K in cash just because you’re not sure.

One common trait across every successful founder is they were relentless. So that’s why I really like this, an obsession about the user. There’s this whole video on YouTube where, are you an internet company? And he says, “Internet-shvinternet doesn’t matter. What matters is the customer.”

That’s what I say when people ask, “Are you a wrapper or do you build your own model?” Yeah, we do both, but it doesn’t matter. What matters is, the answer works. The answer is fast, accurate, readable, nice, the product works. And nobody, if you really want AI to be widespread where every person’s mom and dad are using it, I think that would only happen when people don’t even care what models aren’t running under the hood. So Elon, I’ve like taken inspiration a lot for the raw grit. When everyone says it’s just so hard to do something and this guy just ignores them and just still does it, I think that’s extremely hard. It basically requires doing things through sheer force of will and nothing else. He’s the prime example of it.

Elon Musk
Distribution, hardest thing in any business is distribution. And I read this Walter Isaacson biography of him. He learned the mistakes that, if you rely on others a lot for your distribution, his first company, Zip2 where he tried to build something like a Google Maps, he ended up, as in, the company ended up making deals with putting their technology on other people’s sites and losing direct relationship with the users because that’s good for your business. You have to make some revenue and people pay you. But then in Tesla, he didn’t do that. He actually didn’t go to dealers or anything. He had, dealt the relationship with the users directly. It’s hard. You might never get the critical mass, but amazingly, he managed to make it happen. So I think that sheer force of will and [inaudible 00:51:37] principles thinking, no work is beneath you, I think that is very important. I’ve heard that in Autopilot he has done data himself just to understand how it works. Every detail could be relevant to you to make a good business decision and he’s phenomenal at that.
Lex Fridman
And one of the things you do by understanding every detail is you can figure out how to break through difficult bottlenecks and also how to simplify the system.

When you see what everybody’s actually doing, there’s a natural question if you could see to the first principles of the matter is like, why are we doing it this way? It seems like a lot of bullshit. Like annotation, why are we doing annotation this way? Maybe the user interface is inefficient. Or why are we doing annotation at all? Why can’t it be self-supervised? And you can just keep asking that why question. Do we have to do it in the way we’ve always done? Can we do it much simpler?

Jensen Huang
Aravind Srinivas
Yeah, and this trait is also visible in Jensen, like this real obsession and constantly improving the system, understanding the details. It’s common across all of them. And I think Jensen is pretty famous for saying, “I just don’t even do one-on-ones because I want to know simultaneously from all parts of the system like [inaudible 00:53:03] I just do one is to, and I have 60 direct reports and I made all of them together and that gets me all the knowledge at once and I can make the dots connect and it’s a lot more efficient.” Questioning the conventional wisdom and trying to do things a different way is very important.

Imagine that. 30x is not something that you would easily get. Maybe it’s not 30x in performance, it doesn’t matter. It’s still going to be pretty good. And by the time you match that, that’ll be like Ruben. There’s always innovation happening.

I met him once and I asked him, “How do you handle the success and yet go and work hard?” And he just said, “Because I am actually paranoid about going out of business. Every day I wake up in sweat thinking about how things are going to go wrong.” Because one thing you got to understand, hardware is, you got to actually, I don’t know about the 10, 20 year thing, but you actually do need to plan two years in advance because it does take time to fabricate and get the chip back and you need to have the architecture ready. You might make mistakes in one generation of architecture and that could set you back by two years. Your competitor might get it right. So there’s that drive, the paranoia, obsession about details. You need that. And he’s a great example.

I have a lot of respect for him. I think he went through many years where people just ridiculed or didn’t respect his work as much as they should have, and he still stuck with it. And not just his contributions to Convnets and self-supervised learning and energy-based models and things like that. He also educated a good generation of next scientists like Koray who’s now the CTO of DeepMind, who was a student. The guy who invented DALL-E at OpenAI and Sora was Yann LeCun’s student, Aditya Ramesh. And many others who’ve done great work in this field come from LeCun’s lab like Wojciech Zaremba, one of the OpenAI co-founders. So there’s a lot of people he’s just given as the next generation to that have gone on to do great work. And I would say that his positioning on, he was right about one thing very early on in 2016. You probably remember RL was the real hot at the time. Everyone wanted to do RL and it was not an easy to gain skill. You have to actually go and read MDPs, understand, read some math, bellman equations, dynamic programming, model-based [inaudible 00:59:00].

And then you can decode it into whatever you want in the raw input space using autoregress so a diffusion doesn’t matter. And I think that could also be powerful.

There’s a lot of arguments both directions because people who are afraid of AGI, they’re worried about it being a fundamentally different kind of technology because of how rapidly it could become good. And so the eyeballs, if you have a lot of eyeballs on it, some of those eyeballs will belong to people who are malevolent, and can quickly do harm or try to harness that power to abuse others at a mass scale. But history is laden with people worrying about this new technology is fundamentally different than every other technology that ever came before it. So I tend to trust the intuitions of engineers who are building, who are closest to the metal, who are building the systems. But also those engineers can often be blind to the big picture impact of a technology. So you got to listen to both, but open source, at least at this time seems… While it has risks, seems like the best way forward because it maximizes transparency and gets the most mind, like you said.

Aravind Srinivas
So I think first of all, attention, like Yoshua Bengio wrote this paper with Dzmitry Bahdanau called, Soft Attention, which was first applied in this paper called Align and Translate. Ilya Sutskever wrote the first paper that said, you can just train a simple RNN model, scale it up and it’ll beat all the phrase-based machine translation systems. But that was brute force. There was no attention in it, and spent a lot of Google compute, I think probably like 400 million parameter model or something even back in those days. And then this grad student Bahdanau in Benjio’s lab identifies attention and beats his numbers with [inaudible 01:05:20] compute. So clearly a great idea. And then people at DeepMind figured that this paper called Pixel RNNs figured that you don’t even need RNNs, even though the title is called Pixel RNN. I guess it’s the actual architecture that became popular was WaveNet. And they figured out that a completely convolutional model can do autoregressive modeling as long as you do mass convolutions. The masking was the key idea.

The masking was the key idea.
So you can train in parallel instead of backpropagating through time. You can backpropagate through every input token in parallel. So that way you can utilize the GPU computer a lot more efficiently, because you’re just doing Matmos. And so they just said throw away the RNN. And that was powerful. And so then Google Brain, like Vaswani et al that transformer paper identified that, let’s take the good elements of both. Let’s take attention, it’s more powerful than cons. It learns more higher-order dependencies, because it applies more multiplicative compute. And let’s take the insight in WaveNet that you can just have a all convolutional model that fully parallel matrix multiplies and combine the two together and they built a transformer. And that is the, I would say, it’s almost like the last answer. Nothing has changed since 2017 except maybe a few changes on what the nonlinearities are and how the square descaling should be done. Some of that has changed. And then people have tried mixture of experts having more parameters for the same flop and things like that. But the core transformer architecture has not changed.
Lex Fridman
Isn’t it crazy to you that masking as simple as something like that works so damn well?
Isn’t it crazy to you that masking as simple as something like that works so damn well?
Aravind Srinivas
Yeah, it’s a very clever insight that, you want to learn causal dependencies, but you don’t want to waste your hardware, your compute and keep doing the back propagation sequentially. You want to do as much parallel compute as possible during training. That way, whatever job was earlier running in eight days would run in a single day. I think that was the most important insight. And whether it’s cons or attention… I guess attention and transformers make even better use of hardware than cons, because they apply more compute per flop. Because in a transformer the self-attention operator doesn’t even have parameters. The QK transpose softmax times V has no parameter, but it’s doing a lot of flops. And that’s powerful. It learns multi-order dependencies. I think the insight then OpenAI took from that is, like Ilya Sutskever has been saying unsupervised learning is important. They wrote this paper called Sentiment Neuron, and then Alec Radford and him worked on this paper called GPT-1.

They wrote this paper called Sentiment Neuron, and then Alec Radford and him worked on this paper called GPT-1.
It wasn’t even called GPT-1, it was just called GPT. Little did they know that it would go on to be this big. But just said, let’s revisit the idea that you can just train a giant language model and it’ll learn natural language common sense, that was not scalable earlier because you were scaling up RNNs, but now you got this new transformer model that’s a 100x more efficient at getting to the same performance. Which means if you run the same job, you would get something that’s way better if you apply the same amount of compute. And so they just trained transformer on all the books like storybooks, children’s storybooks, and that got really good. And then Google took that inside and did BERT, except they did bidirectional, but they trained on Wikipedia and books and that got a lot better.
And then OpenAI followed up and said, okay, great. So it looks like the secret sauce that we were missing was data and throwing more parameters. So we’ll get GPT-2, which is like a billion parameter model, and trained on a lot of links from Reddit. And then that became amazing. Produce all these stories about a unicorn and things like that, if you remember.
Lex Fridman
Yeah.
Yeah.
Aravind Srinivas
And then the GPT-3 happened, which is like you just scale up even more data. You take common crawl and instead of one billion go all the way to 175 billion. But that was done through analysis called a scaling loss, which is, for a bigger model, you need to keep scaling the amount of tokens and you train on 300 billion tokens. Now it feels small. These models are being trained on tens of trillions of tokens and trillions of parameters. But this is literally the evolution. Then the focus went more into pieces outside the architecture on data, what data you’re training on, what are the tokens, how dedupe they are, and then the chinchilla inside. It’s not just about making the model bigger, but you want to also make the data set bigger. You want to make sure the tokens are also big enough in quantity and high quality and do the right evals on a lot of reasoning benchmarks.

So I think that ended up being the breakthrough. It’s not like a attention alone was important. Attention, parallel computation, transformer, scaling it up to do unsupervised pre-training, right data and then constant improvements.
Lex Fridman
Well, let’s take it to the end, because you just gave an epic history of LLMs and the breakthroughs of the past 10 years plus. So you mentioned GPT-3, so three, five. How important to you is RLHF, that aspect of it?

It’s not easy to make these systems controllable and well-behaved without the RLHF step. By the way, there’s this terminology for this. It’s not very used in papers, but people talk about it as pre-trained post-trained. And RLHF and supervised fine-tuning are all in post-training phase. And the pre-training phase is the raw scaling on compute. And without good post-training, you’re not going to have a good product. But at the same time, without good pre-training, there’s not enough common sense to actually have the post-training have any effect. You can only teach a generally intelligent person a lot of skills, and that’s where the pre-training is important. That’s why you make the model bigger. The same RLHF on the bigger model ends up like GPT-4 ends up making ChatGPT much better than 3.5. But that data like, oh, for this coding query, make sure the answer is formatted with these markdown and syntax highlighting tool use and knows when to use what tools. We can decompose the query into pieces.

These are all stuff you do in the post-training phase, and that’s what allows you to build products that users can interact with, collect more data, create a flywheel, go and look at all the cases where it’s failing, collect more human annotation on that. I think that’s where a lot more breakthroughs will be made.
Lex Fridman

And the RAG architecture, the Retrieval Augmented architecture. I think there’s an interesting thought experiment here that, we’ve been spending a lot of compute in the pre-training to acquire general common sense, but that seems brute force and inefficient. What you want is a system that can learn like an open book exam. If you’ve written exams in undergrad or grad school where people allowed you to come with your notes to the exam, versus no notes allowed, I think not the same set of people end up scoring number one on both.

Kind of. It memorizes everything. You can ask the question, why do you need to memorize every single fact to be good at reasoning? But somehow that seems like the more and more compute and data you throw at these models, they get better at reasoning. But is there a way to decouple reasoning from facts? And there are some interesting research directions here, like Microsoft has been working on this five models where they’re training small language models. They call it SLMs, but they’re only training it on tokens that are important for reasoning. And they’re distilling the intelligence from GPT-4 on it to see how far you can get if you just take the tokens of GPT-4 on datasets that require you to reason, and you train the model only on that. You don’t need to train on all of regular internet pages, just train it on basic common sense stuff. But it’s hard to know what tokens are needed for that. It’s hard to know if there’s an exhaustive set for that.

But if we do manage to somehow get to a right dataset mix that gives good reasoning skills for a small model, then that’s a breakthrough that disrupts the whole foundation model players, because you no longer need that giant of cluster for training. And if this small model, which has good level of common sense can be applied iteratively, it bootstraps its own reasoning and doesn’t necessarily come up with one output answer, but things for a while bootstraps to calm things for a while. I think that can be truly transformational.
Lex Fridman
Man, there’s a lot of questions there. Is it possible to form that SLM? You can use an LLM to help with the filtering which pieces of data are likely to be useful for reasoning?

Absolutely. And these are the kind of architectures we should explore more, where small models… And this is also why I believe open source is important, because at least it gives you a good base model to start with and try different experiments in the post-training phase to see if you can just specifically shape these models for being good reasoners.

Aravind Srinivas
So chain of thought is this very simple idea where, instead of just training on prompt and completion, what if you could force the model to go through a reasoning step where it comes up with an explanation, and then arrives at an answer. Almost like the intermediate steps before arriving at the final answer. And by forcing models to go through that reasoning pathway, you’re ensuring that they don’t overfit on extraneous patterns, and can answer new questions they’ve not seen before, but at least going through the reasoning chain.

Aravind Srinivas
It’s not that weird that such tricks really help a small model compared to a larger model, which might be even better instruction to you and then more common sense. So these tricks matter less for the, let’s say GPT-4 compared to 3.5. But the key insight is that there’s always going to be prompts or tasks that your current model is not going to be good at. And how do you make it good at that? By bootstrapping its own reasoning abilities. It’s not that these models are unintelligent, but it’s almost that we humans are only able to extract their intelligence by talking to them in natural language. But there’s a lot of intelligence they’ve compressed in their parameters, which is trillions of them. But the only way we get to extract it is through exploring them in natural language.

Correct. So the idea for the STaR paper is that, you take a prompt, you take an output, you have a data set like this, you come up with explanations for each of those outputs, and you train the model on that. Now, there are some imprompts where it’s not going to get it right. Now, instead of just training on the right answer, you ask it to produce an explanation. If you were given the right answer, what is explanation you would provide it, you train on that. And for whatever you got, you just train on the whole string of prompt explanation and output. This way, even if you didn’t arrive at the right answer, if you had been given the hint of the right answer, you’re trying to reason what would’ve gotten me that right answer. And then training on that. And mathematically you can prove that it’s related to the variational, lower bound with the latent.

And I think it’s a very interesting way to use natural language explanations as a latent. That way you can refine the model itself to be the reasoner for itself. And you can think of constantly collecting a new data set where you’re going to be bad at trying to arrive at explanations that will help you be good at it, train on it, and then seek more harder data points, train on it. And if this can be done in a way where you can track a metric, you can start with something that’s like say 30% on some math benchmark and get something like 75, 80%. So I think it’s going to be pretty important. And the way it transcends just being good at math or coding is, if getting better at math or getting better at coding translates to greater reasoning abilities on a wider array of tasks outside of two and could enable us to build agents using those kind of models, that’s when I think it’s going to be getting pretty interesting. It’s not clear yet. Nobody’s empirically shown this is the case.
Lex Fridman
That this couldn’t go to the space of agents.
That this couldn’t go to the space of agents.
Aravind Srinivas
Yeah. But this is a good bet to make that if you have a model that’s pretty good at math and reasoning, it’s likely that it can handle all the Connor cases when you’re trying to prototype agents on top of them.

Curiosity
Lex Fridman
This kind of work hints a little bit of a similar kind of approach to self-play. Do you think it’s possible we live in a world where we get an intelligence explosion from post-training? Meaning like, if there’s some kind of insane world where AI systems are just talking to each other and learning from each other? That’s what this kind of, at least to me, seems like it’s pushing towards that direction. And it’s not obvious to me that that’s not possible.

For self-play go or chess, who won the game? That was signal. And that’s according to the rules of the game. In these AI tasks, of course, for math and coding, you can always verify if something was correct through traditional verifiers. But for more open-ended things like say, predict the stock market for Q3, what is correct? You don’t even know. Okay, maybe you can use historic data. I only give you data until Q1 and see if you predict it well for Q2 and you train on that signal, maybe that’s useful. And then you still have to collect a bunch of tasks like that and create a RL suit for that. Or give agents tasks like a browser and ask them to do things and sandbox it. And completion is based on whether the task was achieved, which will be verified by human. So you do need to set up like a RL sandbox for these agents to play and test and verify-

And get signal from humans at some point. But I guess the idea is that the amount of signal you need relative to how much new intelligence you gain is much smaller. So you just need to interact with humans every once in a while.

Bootstrap, interact and improve. So maybe when recursive self-improvement is cracked, yes, that’s when intelligence explosion happens. Where you’ve cracked it, you know that the same compute when applied iteratively keeps leading you to increase in IQ points or reliability. And then you just decide, I’m just going to buy a million GPUs and just scale this thing up. And then what would happen after that whole process is done? Where there are some humans along the way providing push yes and no buttons, and that could be pretty interesting experiment. We have not achieved anything of this nature yet, at least nothing I’m aware of, unless it’s happening in secret in some frontier lab. But so far it doesn’t seem like we are anywhere close to this.

What makes human special is love, natural beauty to how we live and things like that.

A Berkeley professor, Alyosha Efros’ written some papers on this where in our rail, what happens if you just don’t have any reward signal? And agent just explores based on prediction errors. He showed that you can even complete a whole Mario game or a level, by literally just being curious. Because games are designed that way by the designer to keep leading you to new things. But that’s just works at the game level and nothing has been done to really mimic real human curiosity.

So I feel like even in a world where you call that an AGI, if you feel like you can have a conversation with an AI scientist at the level of Feynman, even in such a world, I don’t think there’s any indication to me that we can mimic Feynman’s curiosity. We could mimic Feynman’s ability to thoroughly research something, and come up with non-trivial answers to something. But can we mimic his natural curiosity about just his period of just being naturally curious about so many different things? And endeavoring to try to understand the right question, or seek explanations for the right question? It’s not clear to me yet.

And then you pay say, $10 million for that job. But then the answer came back with you. It was completely new way to do things. And what is the value of that one particular answer? That would be insane if it worked. So that’s world that, I think we don’t need to really worry about AIs going rogue and taking over the world, but…

It’s less about access to a model’s weights, it’s more access to compute that is putting the world in more concentration of power and few individuals. Because not everyone’s going to be able to afford this much amount of compute to answer the hardest questions.

It’s fluid intelligence, right? The facts, research papers, existing facts about the world, ability to take that, verify what is correct and right, ask the right questions and do it in a chain. And do it for a long time. Not even talking about systems that come back to you after an hour, like a week or a month. Imagine if someone came and gave you a transformer-like paper. Let’s say you’re in 2016 and you asked an AI, an EGI, “I want to make everything a lot more efficient. I want to be able to use the same amount of compute today, but end up with a model a 100x better.” And then the answer ended up being transformer, but instead it was done by an AI instead of Google Brain researchers. Now, what is the value of that? The value of that is like trillion dollars technically speaking. So would you be willing to pay a $100 million for that one job? Yes. But how many people can afford a $100 million for one job? Very few. Some high net worth individuals and some really well-capitalized companies

And do it for a long time. Not even talking about systems that come back to you after an hour, like a week or a month. Imagine if someone came and gave you a transformer-like paper. Let’s say you’re in 2016 and you asked an AI, an EGI, “I want to make everything a lot more efficient. I want to be able to use the same amount of compute today, but end up with a model a 100x better.” And then the answer ended up being transformer, but instead it was done by an AI instead of Google Brain researchers. Now, what is the value of that? The value of that is like trillion dollars technically speaking. So would you be willing to pay a $100 million for that one job? Yes. But how many people can afford a $100 million for one job? Very few. Some high net worth individuals and some really well-capitalized companies

A quick turn to a pothead question. What do you think is the timeline for the thing we’re talking about? If you had to predict, and bet the $100 million that we just made? No, we made a trillion, we paid a 100 million, sorry, on when these kinds of big leaps will be happening. Do you think it’ll be a series of small leaps, like the kind of stuff we saw with GBT, with RLHF? Or is there going to be a moment that’s truly, truly transformational?

I don’t think it’ll be one single moment. It doesn’t feel like that to me. Maybe I’m wrong here, nobody knows. But it seems like it’s limited by a few clever breakthroughs on how to use iterative compute. It’s clear that the more inference compute you throw at an answer, getting a good answer, you can get better answers. But I’m not seeing anything that’s more like, oh, take an answer. You don’t even know if it’s right. And have some notion of algorithmic truth, some logical deductions. Let’s say, you’re asking a question on the origins of Covid, very controversial topic, evidence in conflicting directions. A sign of a higher intelligence is something that can come and tell us that the world’s experts today are not telling us, because they don’t even know themselves.

Can you build an AI that’s like Galileo or Copernicus where it questions our current understanding and comes up with a new position, which will be contrarian and misunderstood, but might end up being true?

And based on which, especially if it’s in the realm of physics, you can build a machine that does something. So like nuclear fusion, it comes up with a contradiction to our current understanding of physics that helps us build a thing that generates a lot of energy, for example. Or even something less dramatic, some mechanism, some machine, something we can engineer and see like, “Holy shit. This is not just a mathematical idea, it’s a theorem prover.”

If we can get to that, then I think we can make a more accurate estimation of the timeline. Today’s systems don’t seem capable of doing anything of this nature.

And maybe that’s just one particular question.

Yeah. Elon’s trying to figure out how to go to Mars and obviously redesigned from Falcon to Starship. If an AI had given him that insight when he started the company itself said, “Look, Elon, I know you’re going to work hard on Falcon, but you need to redesign it for higher payloads and this is the way to go.” That sort of thing will be way more valuable.

That’s true. Yeah. If you have high power thinkers like Elon or I imagine when I’ve had conversation with Ilya Sutskever like just talking about any topic, the ability to think through a thing, I mean, you mentioned PhD student, we can just go to that.

No, you need to insert some element of random seeds where even though the core intelligence capabilities are the same level, they are like different worldviews. And because of that, it forces some element of new signal to arrive at. Both are truth seeking, but they have different worldviews or different perspectives because there’s some ambiguity about the fundamental things and that could ensure that both of them arrive at new truth. It’s not clear how to do all this without hard coding these things yourself.

So I got together my co-founders, Dennis and Johnny, and all we wanted to do was build cool products with LLMs. It was a time when it wasn’t clear where the value would be created. Is it in the model? Is it in the product? But one thing was clear, these generative models that transcended from just being research projects to actual user-facing applications, GitHub Copilot was being used by a lot of people, and I was using it myself, and I saw a lot of people around me using it, Andrej Karpathy was using it, people were paying for it. So this was a moment unlike any other moment before where people were having AI companies where they would just keep collecting a lot of data, but then it would be a small part of something bigger. But for the first time, AI itself was the thing.

Yeah, I mean you can just call it a fancy autocomplete, it’s fine. Except it actually worked at a deeper level than before. And one property I wanted for a company I started was it has to be AI-complete. This was something I took from Larry Page, which is you want to identify a problem where if you worked on it, you would benefit from the advances made in AI. The product would get better. And because the product gets better, more people use it, and therefore that helps you to create more data for the AI to get better. And that makes the product better. That creates the flywheel.

It’s not easy to have this property for most companies don’t have this property. That’s why they’re all struggling to identify where they can use AI. It should be obvious where it should be able to use AI. And there are two products that I feel truly nailed this. One is Google Search, where any improvement in AI, semantic understanding, natural language processing, improves the product and more data makes the embeddings better, things like that. Or self-driving cars where more and more people drive is more data for you and that makes the models better, the vision systems better, the behavior cloning better.

And I always wanted my startup also to be of this nature. But it wasn’t designed to work on consumer search itself. We started off as searching over, the first idea I pitched to the first investor who decided to fund us, Elad Gil. “Hey, we’d love to disrupt Google, but I don’t know how. But one thing I’ve been thinking is, if people stop typing into the search bar and instead just ask about whatever they see visually through a glass?”. I always liked the Google Glass version. It was pretty cool. And he just said, “Hey, look, focus, you’re not going to be able to do this without a lot of money and a lot of people. Identify a edge right now and create something, and then you can work towards the grander vision”. Which is very good advice.

And that’s when we decided, “Okay, how would it look like if we disrupted or created search experiences for things you couldn’t search before?” And we said, “Okay, tables, relational databases. You couldn’t search over them before, but now you can because you can have a model that looks at your question, translates it to some SQL query, runs it against the database. You keep scraping it so that the database is up-to-date and you execute the query, pull up the records and give you the answer.”

Correct. The reason we picked SQL was because we felt like the output entropy is lower, it’s templatized. There’s only a few set of select statements, count, all these things. And that way you don’t have as much entropy as in generic Python code. But that insight turned out to be wrong, by the way.

Just trained on GitHub and some national language. So it’s almost like you should consider it was like programming with computers that had very little RAM. So a lot of hard coding. My co-founders and I would just write a lot of templates ourselves for this query, this is a SQL, this query, this is a SQL, we would learn SQL ourselves. This is also why we built this generic question answering bot because we didn’t know SQL that well ourselves.

This is also why we built this generic question answering bot because we didn’t know SQL that well ourselves.
And then we would do RAG. Given the query, we would pull up templates that were similar-looking template queries and the system would see that build a dynamic few-shot prompt and write a new query for the query you asked and execute it against the database. And many things would still go wrong. Sometimes the SQL would be erroneous. You had to catch errors. It would do like retries. So we built all this into a good search experience over Twitter, which we scraped with academic accounts, this was before Elon took over Twitter. Back then Twitter would allow you to create academic API accounts and we would create lots of them with generating phone numbers, writing research proposals with GPT.
Lex Fridman
Nice.

I would call my projects like VindRank and all these kind of things and then create all these fake academic accounts, collect a lot of tweets, and basically Twitter is a gigantic social graph, but we decided to focus it on interesting individuals because the value of the graph is still pretty sparse, concentrated.

And then we built this demo where you can ask all these sort of questions, stop tweets about AI, like if I wanted to get connected to someone, I’m identifying a mutual follower. And we demoed it to a bunch of people like Yann LeCun, Jeff Dean, Andrej. And they all liked it. Because people like searching about what’s going on about them, about people they are interested in. Fundamental human curiosity, right? And that ended up helping us to recruit good people because nobody took me or my co-founders that seriously. But because we were backed by interesting individuals, at least they were willing to listen to a recruiting pitch.

So what wisdom do you gain from this idea that the initial search over Twitter was the thing that opened the door to these investors, to these brilliant minds that kind of supported you?

I think there’s something powerful about showing something that was not possible before. There is some element of magic to it, and especially when it’s very practical too. You are curious about what’s going on in the world, what’s the social interesting relationships, social graphs. I think everyone’s curious about themselves. I spoke to Mike Kreiger, the founder of Instagram, and he told me that even though you can go to your own profile by clicking on your profile icon on Instagram, the most common search is people searching for themselves on Instagram.

So the reason the first release of Perplexity went really viral because people would just enter their social media handle on the Perplexity search bar. Actually, it’s really funny. We released both the Twitter search and the regular Perplexity search a week apart and we couldn’t index the whole of Twitter, obviously, because we scraped it in a very hacky way. And so we implemented a backlink where if your Twitter handle was not on our Twitter index, it would use our regular search that would pull up few of your tweets and give you a summary of your social media profile.

And so we implemented a backlink where if your Twitter handle was not on our Twitter index, it would use our regular search that would pull up few of your tweets and give you a summary of your social media profile.
And it would come up with hilarious things, because back then it would hallucinate a little bit too. So people allowed it. They either were spooked by it saying, “Oh, this AI knows so much about me.” Or they were like, “Oh, look at this AI saying all sorts of shit about me.” And they would just share the screenshots of that query alone. And that would be like, “What is this AI?” “Oh, it’s this thing called Perplexity. And what do you do is you go and type your handle at it and it’ll give you this thing.” And then people started sharing screenshots of that in Discord forums and stuff. And that’s what led to this initial growth when you’re completely irrelevant to at least some amount of relevance.
But we knew that’s like a one-time thing. It’s not like every way is a repetitive query, but at least that gave us the confidence that there is something to pulling up links and summarizing it. And we decided to focus on that. And obviously we knew that this Twitter search thing was not scalable or doable for us because Elon was taking over and he was very particular that he’s going to shut down API access a lot. And so it made sense for us to focus more on regular search.
Lex Fridman
That’s a big thing to take on, web search. That’s a big move.

Honestly, the way we thought about it was, let’s release this. There’s nothing to lose. It’s a very new experience. People are going to like it, and maybe some enterprises will talk to us and ask for something of this nature for their internal data, and maybe we could use that to build a business. That was the extent of our ambition. That’s why most companies never set out to do what they actually end up doing. It’s almost accidental.

That was the extent of our ambition. That’s why most companies never set out to do what they actually end up doing. It’s almost accidental.
So for us, the way it worked was we put this out and a lot of people started using it. I thought, “Okay, it’s just a fad and the usage will die.” But people were using it in the time, we put it out on December 7th, 2022, and people were using it even in the Christmas vacation. I thought that was a very powerful signal. Because there’s no need for people when they hang out with their family and chilling on vacation to come use a product by completely unknown startup with an obscure name. So I thought there was some signal there. And okay, we initially didn’t have it conversational. It was just giving only one single query. You type in, you get an answer with summary with the citation. You had to go and type a new query if you wanted to start another query. There was no conversational or suggested questions, none of that. So we launched a conversational version with the suggested questions a week after New Year, and then the usage started growing exponentially.
And most importantly, a lot of people are clicking on the related questions too. So we came up with this vision. Everybody was asking me, “Okay, what is the vision for the company? What’s the mission?” I had nothing. It was just explore cool search products. But then I came up with this mission along with the help of my co-founders that, “Hey, it’s not just about search or answering questions. It’s about knowledge. Helping people discover new things and guiding them towards it, not necessarily giving them the right answer, but guiding them towards it.” And so we said, “We want to be the world’s most knowledge-centric company.” It was actually inspired by Amazon saying they wanted to be the most customer-centric company on the planet. We want to obsess about knowledge and curiosity.
And we felt like that is a mission that’s bigger than competing with Google. You never make your mission or your purpose about someone else because you’re probably aiming low, by the way, if you do that. You want to make your mission or your purpose about something that’s bigger than you and the people you’re working with. And that way you’re thinking completely outside the box too. And Sony made it their mission to put Japan on the map, not Sony on the map.
Lex Fridman

Correct. Organizing the information, making it universally accessible and useful. It’s very powerful. Except it’s not easy for them to serve that mission anymore. And nothing stops other people from adding onto that mission, re-think that mission too.

Wikipedia also in some sense does that. It does organize the information around the world and makes it accessible and useful in a different way. Perplexity does it in a different way, and I’m sure there’ll be another company after us that does it even better than us, and that’s good for the world.
RAG
Lex Fridman
So can you speak to the technical details of how Perplexity works? You’ve mentioned already RAG, retrieval augmented generation. What are the different components here? How does the search happen? First of all, what is RAG? What does the LLM do at a high level? How does the thing work?

Aravind Srinivas
Yeah. So RAG is retrieval augmented generation. Simple framework. Given a query, always retrieve relevant documents and pick relevant paragraphs from each document and use those documents and paragraphs to write your answer for that query. The principle in Perplexity is you’re not supposed to say anything that you don’t retrieve, which is even more powerful than RAG because RAG just says, “Okay, use this additional context and write an answer.” But we say, “Don’t use anything more than that too.” That way we ensure a factual grounding. “And if you don’t have enough information from documents you retrieve, just say, ‘We don’t have enough search resource to give you a good answer.'”

Lex Fridman
So where is there room for hallucination to seep in?
So where is there room for hallucination to seep in?
Aravind Srinivas
Yeah, there are multiple ways it can happen. One is you have all the information you need for the query, the model is just not smart enough to understand the query at a deeply semantic level and the paragraphs at a deeply semantic level and only pick the relevant information and give you an answer. So that is the model skill issue. But that can be addressed as models get better and they have been getting better.

So that is the model skill issue. But that can be addressed as models get better and they have been getting better.
Now, the other place where hallucinations can happen is you have poor snippets, like your index is not good enough. So you retrieve the right documents, but the information in them was not up-to-date, was stale or not detailed enough. And then the model had insufficient information or conflicting information from multiple sources and ended up getting confused.
And the third way it can happen is you added too much detail to the model. Like your index is so detailed, your snippets are so…you use the full version of the page and you threw all of it at the model and asked it to arrive at the answer, and it’s not able to discern clearly what is needed and throws a lot of irrelevant stuff to it and that irrelevant stuff ended up confusing it and made it a bad answer.
The fourth way is you end up retrieving completely irrelevant documents too. But in such a case, if a model is skillful enough, it should just say, “I don’t have enough information.”
So there are multiple dimensions where you can improve a product like this to reduce hallucinations, where you can improve the retrieval, you can improve the quality of the index, the freshness of the pages in the index, and you can include the level of detail in the snippets. You can improve the model’s ability to handle all these documents really well. And if you do all these things well, you can keep making the product better.
Lex Fridman
So it’s kind of incredible. I get to see directly because I’ve seen answers, in fact for a Perplexity page that you’ve posted about, I’ve seen ones that reference a transcript of this podcast. And it’s cool how it gets to the right snippet. Probably some of the words I’m saying now and you’re saying now will end up in a Perplexity answer.

So the indexing is fascinating. So is there something you could say about some interesting aspects of how the indexing is done?
Aravind Srinivas
Yeah, so indexing is multiple parts. Obviously you have to first build a crawler, which is like Google has Googlebot, we have PerplexityBot, Bingbot, GPTBot. There’s a bunch of bots that crawl the web.

Aravind Srinivas
Lots, like even deciding what to put it in the queue, which web pages, which domains, and how frequently all the domains need to get crawled. And it’s not just about knowing which URLs, it’s just deciding what URLs to crawl, but how you crawl them. You basically have to render, headless render, and then websites are more modern these days, it’s not just the HTML, there’s a lot of JavaScript rendering. You have to decide what’s the real thing you want from a page.

And obviously people have robots that text file, and that’s a politeness policy where you should respect the delay time so that you don’t overload their servers by continually crawling them. And then there is stuff that they say is not supposed to be crawled and stuff that they allow to be crawled. And you have to respect that, and the bot needs to be aware of all these things and appropriately crawl stuff.
Lex Fridman
But most of the details of how a page works, especially with JavaScript, is not provided to the bot, I guess, to figure all that out.

Aravind Srinivas
Yeah, it depends so some publishers allow that so that they think it’ll benefit their ranking more. Some publishers don’t allow that. And you need to keep track of all these things per domains and subdomains.

And then you also need to decide the periodicity with which you recrawl. And you also need to decide what new pages to add to this queue based on hyperlinks.
And then you also need to decide the periodicity with which you recrawl. And you also need to decide what new pages to add to this queue based on hyperlinks.
So that’s the crawling. And then there’s a part of fetching the content from each URL. And once you did that through the headless render, you have to actually build the index now and you have to reprocess, you have to post-process all the content you fetched, which is the raw dump, into something that’s ingestible for a ranking system.
So that requires some machine learning, text extraction. Google has this whole system called Now Boost that extracts the relevant metadata and relevant content from each raw URL content.
Lex Fridman
Is that a fully machine learning system with embedding into some kind of vector space?

It’s not purely vector space. It’s not like once the content is fetched, there is some bird m-
Aravind Srinivas
… once the content is fetched, there’s some BERT model that runs on all of it and puts it into a big, gigantic vector database which you retrieve from. It’s not like that, because packing all the knowledge about a webpage into one vector space representation is very, very difficult. First of all, vector embeddings are not magically working for text. It’s very hard to understand what’s a relevant document to a particular query. Should it be about the individual in the query or should it be about the specific event in the query or should it be at a deeper level about the meaning of that query, such that the same meaning applying to a different individual should also be retrieved? You can keep arguing. What should a representation really capture? And it’s very hard to make these vector embeddings have different dimensions, be disentangled from each other, and capturing different semantics. This is the ranking part, by the way. There’s the indexing part, assuming you have a post-process version for URL, and then there’s a ranking part that, depending on the query you ask, fetches the relevant documents from the index and some kind of score.

And that’s where, when you have billions of pages in your index and you only want the top K, you have to rely on approximate algorithms to get you the top K.
Lex Fridman
So that’s the ranking, but that step of converting a page into something that could be stored in a vector database, it just seems really difficult.
So that’s the ranking, but that step of converting a page into something that could be stored in a vector database, it just seems really difficult.
Aravind Srinivas
It doesn’t always have to be stored entirely in vector databases. There are other data structures you can use and other forms of traditional retrieval that you can use. There is an algorithm called BM25 precisely for this, which is a more sophisticated version of TF-IDF. TF-IDF is term frequency times inverse document frequency, a very old-school information retrieval system that just works actually really well even today. And BM25 is a more sophisticated version of that, that is still beating most embeddings on ranking. When OpenAI released their embeddings, there was some controversy around it because it wasn’t even beating BM25 on many retrieval benchmarks, not because they didn’t do a good job. BM25 is so good. So this is why just pure embeddings and vector spaces are not going to solve the search problem. You need the traditional term-based retrieval. You need some kind of Ngram-based retrieval.

Correct, but not in a per-query basis. You can do that too when you’re small just to delight users, but it doesn’t scale. At the scale of queries you handle, as you keep going in a logarithmic dimension, you go from 10,000 queries a day to 100,000 to a million to 10 million, you’re going to encounter more mistakes, so you want to identify fixes that address things at a bigger scale.

Aravind Srinivas
I think LLMs really help there. So what LLMs add is even if your initial retrieval doesn’t have a amazing set of documents, like it has really good recall but not as high a precision, LLMs can still find a needle in the haystack and traditional search cannot, because they’re all about precision and recall simultaneously. In Google, even though we call it 10 blue links, you get annoyed if you don’t even have the right link in the first three or four. The eye is so tuned to getting it right. LLMs are fine. You get the right link maybe in the 10th or ninth. You feed it in the model. It can still know that that was more relevant than the first. So that flexibility allows you to rethink where to put your resources in terms of whether you want to keep making the model better or whether you want to make the retrieval stage better. It’s a trade-off. In computer science, it’s all about trade-offs at the end.

So one of the things we should say is that the model, this is the pre-trained LLM, is something that you can swap out in Perplexity. So it could be GPT-4o, it could be Claude 3, it can be Llama. Something based on Llama 3.

Advanced model trained by Perplexity. I like how you added advanced model. It sounds way more sophisticated. I like it. Sonar Large. Cool. And you could try that.

It’s going to be faster than Claude models or 4o because we are pretty good at inferencing it ourselves. We host it and we have a cutting-edge API for it.

Does the user care if Perplexity has the most dominant model in order to come and use the product? No. Does the user care about a good answer? Yes. So whatever model is providing us the best answer, whether we fine-tuned it from somebody else’s base model or a model we host ourselves, it’s okay.

Yeah, we are not taking off-the-shelf models from anybody. We have customized it for the product. Whether we own the weights for it or not is something else. So I think there’s also power to design the product to work well with any model. If there are some idiosyncrasies of any model, it shouldn’t affect the product.

So it’s really responsive. How do you get the latency to be so low and how do you make it even lower?
So it’s really responsive. How do you get the latency to be so low and how do you make it even lower?
Aravind Srinivas
We took inspiration from Google. There’s this whole concept called tail latency. It’s a paper by Jeff Dean and another person where it’s not enough for you to just test a few queries, see if there’s fast, and conclude that your product is fast. It’s very important for you to track the P90 and P99 latencies, which is the 90th and 99th percentile. Because if a system fails 10% of the times and you have a lot of servers, you could have certain queries that are at the tail failing more often without you even realizing it. And that could frustrate some users, especially at a time when you have a lot of queries, suddenly a spike. So it’s very important for you to track the tail latency and we track it at every single component of our system, be it the search layer or the LLM layer.

So it’s very important for you to track the tail latency and we track it at every single component of our system, be it the search layer or the LLM layer.
In the LLM, the most important thing is the throughput and the time to first token. We usually refer to it as TTFT, time to first token, and the throughput, which decides how fast you can stream things. Both are really important. And of course, for models that we don’t control in terms of serving, like OpenAI or Anthropic, we are reliant on them to build a good infrastructure. And they are incentivized to make it better for themselves and customers, so that keeps improving. And for models we serve ourselves like Llama-based models, we can work on it ourselves by optimizing at the kernel level. So there, we work closely with NVIDIA, who’s an investor in us, and we collaborate on this framework called TensorRT-LLM. And if needed, we write new kernels, optimize things at the level of making sure the throughput is pretty high without compromising on latency.
Lex Fridman
Is there some interesting complexities that have to do with keeping the latency low and just serving all of the stuff? The TTFT, when you scale up as more and more users get excited, a couple of people listen to this podcast and they’re like, holy shit, I want to try Perplexity. They’re going to show up. What does the scaling of compute look like, almost from a CEO startup perspective?

Yeah, you’ve got to make decisions. Should I go spend like 10 million or 20 million more and buy more GPUs or should I go and pay one of the model providers like five to 10 million more and then get more compute capacity from them?

Aravind Srinivas
It keeps changing, the dynamics. By the way, everything’s on cloud. Even the models we serve are on some cloud provider. It’s very inefficient to go build your own data center right now at the stage we are. I think it’ll matter more when we become bigger. But also, companies like Netflix still run on AWS and have shown that you can still scale with somebody else’s cloud solution.

Let’s ask Perplexity, man. Does Netflix use AWS? Yes, Netflix uses Amazon Web Service, AWS, for nearly all its computing and storage needs. Okay. Well, the company uses over 100,000 server instances on AWS and has built a virtual studio in the cloud to enable collaboration among artists and partners worldwide. Netflix’s decision to use AWS is rooted in the scale and breadth of services AWS offers. Related questions. What specific services does Netflix use from AWS? How does Netflix ensure data security? What are the main benefits Netflix gets from using… Yeah, if I was by myself, I’d be going down a rabbit hole right now.

Well, there’s a clear competition between YouTube, and of course Prime Video’s also a competitor, but it’s sort of a thing that, for example, Shopify is built on Google Cloud. Snapchat uses Google Cloud. Walmart uses Azure. So there are examples of great internet businesses that do not necessarily have their own data centers. Facebook have their own data center, which is okay. They decided to build it right from the beginning. Even before Elon took over Twitter, I think they used to use AWS and Google for their deployment.

Now I think he has this mentality that it all has to be in-house, but it frees you from working on problems that you don’t need to be working on when you’re scaling up your startup. Also, AWS infrastructure is amazing. It’s not just amazing in terms of its quality. It also helps you to recruit engineers easily, because if you’re on AWS and all engineers are already trained on using AWS, so the speed at which they can ramp up is amazing.

Yeah, Elon said it’s not just about the core gigawatt. The point I clearly made in the poll was equivalent, so it doesn’t have to be literally million each wonders, but it could be fewer GPUs of the next generation that match the capabilities of the million H100s at lower power consumption grade, whether it be one gigawatt or 10 gigawatt. I don’t know. It’s a lot of power energy. And I think the kind of things we talked about on the inference compute being very essential for future highly capable AI systems, or even to explore all these research directions like models bootstrapping of their own reasoning, doing their own inference, you need a lot of GPUs.

Right now, it seems like that’s where things are headed in terms of whoever is really competing on the AGI race, like the frontier models. But any breakthrough can disrupt that. If you can decouple reasoning and facts and end up with much smaller models that can reason really well, you don’t need a million H100 equivalent cluster.

Aravind Srinivas
I think all the traditional wisdom applies. I’m not going to say none of that matters. Relentless determination, grit, believing in yourself and others. All these things matter, so if you don’t have these traits, I think it’s definitely hard to do a company. But you deciding to do a company despite all this clearly means you have it or you think you have it. Either way, you can fake it till you have it. I think the thing that most people get wrong after they’ve decided to start a company is work on things they think the market wants. Not being passionate about any idea but thinking, okay, look, this is what will get me venture funding. This is what will get me revenue or customers. That’s what will get me venture funding. If you work from that perspective, I think you’ll give up beyond the point because it’s very hard to work towards something that was not truly important to you. Do you really care?

And we work on search. I really obsessed about search even before starting Perplexity. My co-founder, Dennis, first job was at Bing. And then my co-founders, Dennis and Johnny, worked at Quora together and they built Quora Digest, which is basically interesting threads every day of knowledge based on your browsing activity. So we were all already obsessed about knowledge and search, so very easy for us to work on this without any immediate dopamine hits because as dopamine hit we get just from seeing search quality improve. If you’re not a person that gets that and you really only get dopamine hits from making money, then it’s hard to work on hard problems. So you need to know what your dopamine system is. Where do you get your dopamine from? Truly understand yourself, and that’s what will give you the founder market or founder product fit.
Lex Fridman
And it’ll give you the strength to persevere until you get there.

Correct. And so start from an idea you love, make sure it’s a product you use and test, and market will guide you towards making it a lucrative business by its own capitalistic pressure. But don’t start in the other way where you started from an idea that you think the market likes and try to like it yourself, because eventually you’ll give up or you’ll be supplanted by somebody who actually has genuine passion for that thing.

It’s a lot. I think you need to figure out your own way to cope and have your own support system or else it’s impossible to do this. I have a very good support system through my family. My wife is insanely supportive of this journey. It’s almost like she cares equally about Perplexity as I do, uses the product as much or even more, gives me a lot of feedback and any setbacks that she’s already warning me of potential blind spots, and I think that really helps. Doing anything great requires suffering and dedication. Jensen calls it suffering. I just call it commitment and dedication. And you’re not doing this just because you want to make money, but you really think this will matter. And it’s almost like you have to be aware that it’s a good fortune to be in a position to serve millions of people through your product every day. It’s not easy. Not many people get to that point. So be aware that it’s good fortune and work hard on trying to sustain it and keep growing it.

It’s tough though because in the early days of a startup, I think there’s probably really smart people like you, you have a lot of options. You could stay in academia, you can work at companies, have higher position in companies working on super interesting projects.

Yeah. That’s why all founders are diluted, at the beginning at least. If you actually rolled out model-based [inaudible 02:26:13], if you actually rolled out scenarios, most of the branches, you would conclude that it’s going to be failure.

Interestingly, Larry Page comes from that background. Human-computer interaction. That’s what helped them arrive with new insights to search than people who are just working on NLP, so I think that’s another thing that realized that new insights and people who are able to make new connections are likely to be a good founder too.

By the way, this goes into the whole what do you really want? Some people don’t want to work hard, and I don’t want to make any point here that says a life where you don’t work hard is meaningless. I don’t think that’s true either. But if there is a certain idea that really just occupies your mind all the time, it’s worth making your life about that idea and living for it, at least in your late teens and early twenties, mid-twenties. Because that’s the time when you get that decade or that 10,000 hours of practice on something that can be channelized into something else later, and it’s really worth doing that.

I remember when I told people I’m going to do a PhD, most people said PhD is a waste of time. If you go work at Google after you complete your undergraduate, you’ll start off with a salary like 150K or something. But at the end of four or five years, you would have progressed to a senior or staff level and be earning a lot more. And instead, if you finish your PhD and join Google, you would start five years later at the entry level salary. What’s the point? But they viewed life like that. Little did they realize that no, you’re optimizing with a discount factor that’s equal to one or not a discount factor that’s close to zero.

And I watched YouTube videos of him saying how all day he would just hang out and analyze YouTube videos, like watch patterns of what makes the views go up and study, study, study. That’s the 10,000 hours of practice. Messi has this code, or maybe it’s falsely attributed to him. This is the internet. You can’t believe what you read. But “I worked for decades to become an overnight hero,” or something like that.

I like his vulnerabilities, his openness about wanting to be the best. The human who came closest to Messi is actually an achievement, considering Messi is pretty supernatural.

Similarly, in tennis, there’s another example. Novak Djokovic. Controversial, not as liked as Federer or Nadal, actually ended up beating them. He’s objectively the GOAT, and did that by not starting off as the best.

Yeah, it’s more relatable. You can derive more inspiration. There are some people you just admire but not really can get inspiration from them. And there are some people you can clearly connect dots to yourself and try to work towards that.

Future of search
Lex Fridman
So if you just put on your visionary hat, look into the future, what do you think the future of search looks like? And maybe even let’s go with the bigger pothead question. What does the future of the internet, the web look like? So what is this evolving towards? And maybe even the future of the web browser, how we interact with the internet.

Aravind Srinivas
If you zoom out, before even the internet, it’s always been about transmission of knowledge. That’s a bigger thing than search. Search is one way to do it. The internet was a great way to disseminate knowledge faster and started off with organization by topics, Yahoo, categorization, and then better organization of links. Google. Google also started doing instant answers through the knowledge panels and things like that. I think even in 2010s, one third of Google traffic, when it used to be like 3 billion queries a day, was just instant answers from-

Aravind Srinivas
… just answers, instant answers from the Google Knowledge Graph, which is basically from the Freebase and Wikidata stuff. So it was clear that at least 30 to 40% of search traffic is just answers. And even the rest you can say deeper answers like what we’re serving right now.
… just answers, instant answers from the Google Knowledge Graph, which is basically from the Freebase and Wikidata stuff. So it was clear that at least 30 to 40% of search traffic is just answers. And even the rest you can say deeper answers like what we’re serving right now.
But what is also true is that with the new power of deeper answers, deeper research, you’re able to ask kind of questions that you couldn’t ask before. Like could you have asked questions like, “Is AWS on Netflix” without an answer box? It’s very hard or clearly explaining the difference between search and answer engines. So that’s going to let you ask a new kind of question, new kind of knowledge dissemination. And I just believe that we are working towards neither search or answer engine but just discovery, knowledge discovery. That’s the bigger mission and that can be catered to through chatbots, answerbots, voice form factor usage, but something bigger than that is guiding people towards discovering things. I think that’s what we want to work on at Perplexity, the fundamental human curiosity.
Lex Fridman
So there’s this collective intelligence of the human species sort of always reaching out for more knowledge and you’re giving it tools to reach out at a faster rate.
So there’s this collective intelligence of the human species sort of always reaching out for more knowledge and you’re giving it tools to reach out at a faster rate.

Correct.
Lex Fridman
Do you think the measure of knowledge of the human species will be rapidly increasing over time?
Do you think the measure of knowledge of the human species will be rapidly increasing over time?
Aravind Srinivas
I hope so. And even more than that, if we can change every person to be more truth-seeking than before just because they are able to, just because they have the tools to, I think it’ll lead to a better, well, more knowledge. And fundamentally, more people are interested in fact-checking and uncovering things rather than just relying on other humans and what they hear from other people, which always can be politicized or having ideologies.

And fundamentally, more people are interested in fact-checking and uncovering things rather than just relying on other humans and what they hear from other people, which always can be politicized or having ideologies.
So I think that sort of impact would be very nice to have. I hope that’s the internet we can create. Through the Pages project we’re working on, we’re letting people create new articles without much human effort. And the insight for that was your browsing session, your query that you asked on Perplexity doesn’t need to be just useful to you. Jensen says this in his thing that, “I do [inaudible 02:37:41] is to ends and I give feedback to one person in front of other people, not because I want to put anyone down or up, but that we can all learn from each other’s experiences.”
Why should it be that only you get to learn from your mistakes? Other people can also learn or another person can also learn from another person’s success. So that was inside that. Okay, why couldn’t you broadcast what you learned from one Q&A session on Perplexity to the rest of the world? So I want more such things. This is just the start of something more where people can create research articles, blog posts, maybe even a small book on a topic. If I have no understanding of search, let’s say, and I wanted to start a search company, it will be amazing to have a tool like this where I can just go and ask, “How does bots work? How do crawls work? What is ranking? What is BM25? In one hour of browsing session, I got knowledge that’s worth one month of me talking to experts. To me, this is bigger than search on internet. It’s about knowledge.
Lex Fridman
Yeah. Perplexity Pages is really interesting. So there’s the natural Perplexity interface where you just ask questions, Q&A, and you have this chain. You say that that’s a kind of playground that’s a little bit more private. Now, if you want to take that and present that to the world in a little bit more organized way, first of all, you can share that, and I have shared that by itself.

Yeah.

But if you want to organize that in a nice way to create a Wikipedia-style page, you could do that with Perplexity Pages. The difference there is subtle, but I think it’s a big difference in the actual, what it looks like.

So it is true that there is certain Perplexity sessions where I ask really good questions and I discover really cool things, and that by itself could be a canonical experience that, if shared with others, they could also see the profound insight that I have found.
Aravind Srinivas
Yeah.
Yeah.
Lex Fridman
And it’s interesting to see what that looks like at scale. I would love to see other people’s journeys because my own have been beautiful because you discover so many things. There’s so many aha moments. It does encourage the journey of curiosity. This is true.

Aravind Srinivas
Yeah, exactly. That’s why on our Discover tab, we’re building a timeline for your knowledge. Today it’s curated but we want to get it to be personalized to you. Interesting news about every day. So we imagine a future where the entry point for a question doesn’t need to just be from the search bar. The entry point for a question can be you listening or reading a page, listening to a page being read out to you, and you got curious about one element of it and you just asked a follow-up question to it.

That’s why I’m saying it’s very important to understand your mission is not about changing the search. Your mission is about making people smarter and delivering knowledge.

How many alien civilizations are in the universe? That’s a journey that I’ll continue later for sure. Reading National Geographic. It’s so cool. By the way, watching the pro-search operate, it gives me a feeling like there’s a lot of thinking going on. It’s cool.

Yeah, okay. Going to the Drake Equation, based on the search results, there is no definitive answer on the exact number of alien civilizations in the universe. And then it goes to the Drake Equation. Recent estimates in 20 … Wow, well done. Based on the size of the universe and the number of habitable planets, SETI, what are the main factors in the Drake Equation? How do scientists determine if a planet is habitable? Yeah, this is really, really, really interesting.

There’s a reason for that. Twitter is great. It serves many things. There’s human drama in it. There’s news. There’s knowledge you gain. But some people just want the knowledge, some people just want the news without any drama, and a lot of people have gone and tried to start other social networks for it, but the solution may not even be in starting another social app. Like Threads tried to say, “Oh yeah, I want to start Twitter without all the drama.” But that’s not the answer. The answer is as much as possible try to cater to human curiosity, but not the human drama.

You maximize the … Well, actually, the thing I actually mostly try to maximize, and Rogan’s been an inspiration in this, is maximizing my own curiosity.

One of the things that I read on the [inaudible 02:44:48] page for Perplexity is if you want to learn about nuclear fission and you have a PhD in math, it can be explained. If you want to learn about nuclear fission and you are in middle school, it can be explained. So what is that about? How can you control the depth and the level of the explanation that’s provided? Is that something that’s possible?

I didn’t even know what an MOU means or an LOI, all these things. They just throw acronyms and I didn’t know what a SAFE is, Simple Acronym for Future Equity that Y Combinator came up with. And I just needed these kinds of tools to answer these questions for me. And at the same time, when I’m trying to learn something latest about LLMs, like say about the star paper, I’m pretty detailed. I’m actually wanting equations. So I asked, “Explain, give me equations, give me a detailed research of this,” and it understands that.

So that’s what we mean about Page where this is not possible with traditional search. You cannot customize the UI. You cannot customize the way the answer is given to you. It’s like a one-size-fits-all solution. That’s why even in our marketing videos we say we are not one-size-fits-all and neither are you. Like you, Lex, would be more detailed and [inaudible 02:46:56] on certain topics, but not on certain others.

But I would allow product to be where you just ask, “Give me an answer.” Like Feynman would explain this to me or because Einstein has this code, I don’t even know if it’s this code again. But if it’s a good code, you only truly understand something if you can explain it to your grandmom.

Not everything’s a trivial metaphor. What do you think about the context window, this increasing length of the context window? Does that open up possibilities when you start getting to a hundred thousand tokens, a million tokens, 10 million tokens, a hundred million … I don’t know where you can go. Does that fundamentally change the whole set of possibilities?

Aravind Srinivas
It does in some ways. It doesn’t matter in certain other ways. I think it lets you ingest a more detailed version of the Pages while answering a question, but note that there’s a trade-off between context size increase and the level of instruction following capability.
It does in some ways. It doesn’t matter in certain other ways. I think it lets you ingest a more detailed version of the Pages while answering a question, but note that there’s a trade-off between context size increase and the level of instruction following capability.
So most people, when they advertise new context window increase, they talk a lot about finding the needle in the haystack sort of evaluation metrics and less about whether there’s any degradation in the instruction following performance. So I think that’s where you need to make sure that throwing more information at a model doesn’t actually make it more confused. It’s just having more entropy to deal with now and might even be worse. So I think that’s important. And in terms of what new things it can do, I feel like it can do internal search a lot better. And that’s an area that nobody’s really cracked, like searching over your own files, searching over your Google Drive or Dropbox. And the reason nobody cracked that is because the indexing that you need to build for that is a very different nature than web indexing. And instead, if you can just have the entire thing dumped into your prompt and ask it to find something, it’s probably going to be a lot more capable. And given that the existing solution is already so bad, I think this will feel much better even though it has its issues.
And the other thing that will be possible is memory, though not in the way people are thinking where I’m going to give it all my data and it’s going to remember everything I did, but more that it feels like you don’t have to keep reminding it about yourself. And maybe it will be useful, maybe not so much as advertised, but it’s something that’s on the cards. But when you truly have systems that I think that’s where memory becomes an essential component, where it’s lifelong, it knows when to put it into a separate database or data structure. It knows when to keep it in the prompt. And I like more efficient things, so just systems that know when to take stuff in the prompt and put it somewhere else and retrieve when needed. I think that feels much more an efficient architecture than just constantly keeping increasing the context window. That feels like brute force, to me at least.

On the AGI front, Perplexity is fundamentally, at least for now, a tool that empowers humans.

So I think curiosity makes humans special and we want to cater to that. That’s the mission of the company, and we harness the power of AI and all these frontier models to serve that. And I believe in a world where even if we have even more capable cutting-edge AIs, human curiosity is not going anywhere and it’s going to make humans even more special. With all the additional power, they’re going to feel even more empowered, even more curious, even more knowledgeable in truth-seeking and it’s going to lead to the beginning of infinity.

Do you think there’ll be a romantic relationship between humans and robots?
Do you think there’ll be a romantic relationship between humans and robots?
Aravind Srinivas
It’s possible. I mean, already there are apps like Replika and character.ai and the recent OpenAI, that Samantha voice that it demoed where it felt like are you really talking to it because it’s smart or is it because it’s very flirty? It’s not clear. And Karpathy even had a tweet like, “The killer app was Scarlett Johansson, not codebots.” So it was a tongue-in-cheek comment. I don’t think he really meant it, but it’s possible those kinds of futures are also there. Loneliness is one of the major problems in people. That said, I don’t want that to be the solution for humans seeking relationships and connections. I do see a world where we spend more time talking to AIs than other humans, at least for our work time. It’s easier not to bother your colleague with some questions. Instead, you just ask a tool. But I hope that gives us more time to build more relationships and connections with each other.

You can think about it as therapy, but that’s what great friendship is about. You can bond, you can be vulnerable with each other and that kind of stuff.

Aravind Srinivas
Yeah, but my hope is that in a world where work doesn’t feel like work, we can all engage in stuff that’s truly interesting to us because we all have the help of AIs that help us do whatever we want to do really well. And the cost of doing that is also not that high. We will all have a much more fulfilling life and that way have a lot more time for other things and channelize that energy into building true connections.

Lex Fridman
Well, yes, but the thing about human nature is it’s not all about curiosity in the human mind. There’s dark stuff, there’s demons, there’s dark aspects of human nature that needs to be processed. The Jungian Shadow and, for that, curiosity doesn’t necessarily solve that.

I’m just talking about the Maslow’s hierarchy of needs like food and shelter and safety, security. But then the top is actualization and fulfillment. And I think that can come from pursuing your interests, having work feel like play, and building true connections with other fellow human beings and having an optimistic viewpoint about the future of the planet. Abundance of intelligence is a good thing. Abundance of knowledge is a good thing. And I think most zero-sum mentality will go away when you feel there’s no real scarcity anymore.

That’s my hope but some of the things you mentioned could also happen. People building a deeper emotional connection with their AI chatbots or AI girlfriends or boyfriends can happen. And we’re not focused on that sort of a company. From the beginning, I never wanted to build anything of that nature, but whether that can happen … In fact, I was even told by some investors, “You guys are focused on hallucination. Your product is such that hallucination is a bug. AIs are all about hallucinations. Why are you trying to solve that? Make money out of it. And hallucination is a feature in which product? Like AI girlfriends or AI boyfriends. So go build that, bots like different fantasy fiction.” I said, “No, I don’t care. Maybe it’s hard, but I want to walk the harder path.”

Yeah, it is a hard path although I would say that human AI connection is also a hard path to do it well in a way that humans flourish, but it’s a fundamentally different problem.

Lex Fridman
Absolutely. I should say the same thing Perplexity is trying to solve also feels dangerous because you’re trying to present truth and that can be manipulated with more and more power that’s gained. So to do it right, to do knowledge discovery and truth discovery in the right way, in an unbiased way, in a way that we’re constantly expanding our understanding of others and wisdom about the world, that’s really hard.

But at least there is a science to it that we understand like what is truth, at least to a certain extent. We know through our academic backgrounds that truth needs to be scientifically backed and peer reviewed, and a bunch of people have to agree on it. Sure. I’m not saying it doesn’t have its flaws and there are things that are widely debated, but here I think you can just appear not to have any true emotional connection. So you can appear to have a true emotional connection but not have anything.

So I would love personally AIs that are trying to work with us to understand what we truly want out of life and guide us towards achieving it. That’s less of a Samantha thing and more of a coach.

Well, that was what Samantha wanted to do, a great partner, a great friend. They’re not a great friend because you’re drinking a bunch of beers and you’re partying all night. They’re great because you might be doing some of that, but you’re also becoming better human beings in the process. Like lifelong friendship means you’re helping each other flourish.

I think we don’t have an AI coach where you can actually just go and talk to them. This is different from having AI Ilya Sutskever or something. It’s almost like that’s more like a great consulting session with one of the world’s leading experts. But I’m talking about someone who’s just constantly listening to you and you respect them and they’re almost like a performance coach for you. I think that’s going to be amazing and that’s also different from an AI Tutor. That’s why different apps will serve different purposes. And I have a viewpoint of what are really useful. I’m okay with people disagreeing with this.

There’s a lot of paths to dystopia. This computer is sitting on one of them, Brave New world. There’s a lot of ways that seem pleasant, that seem happy on the surface but in the end are actually dimming the flame of human consciousness, human intelligence, human flourishing in a counterintuitive way. So the unintended consequences of a future that seems like a utopia but turns out to be a dystopia. What gives you hope about the future?

Again, I’m kind of beating the drum here, but for me it’s all about curiosity and knowledge. And I think there are different ways to keep the light of consciousness, preserving it, and we all can go about in different paths. For us, it’s about making sure that it’s even less about that sort of thinking. I just think people are naturally curious. They want to ask questions and we want to serve that mission.

And a lot of confusion exists mainly because we just don’t understand things. We just don’t understand a lot of things about other people or about just how the world works. And if our understanding is better, we all are grateful. “Oh wow. I wish I got to that realization sooner. I would’ve made different decisions and my life would’ve been higher quality and better.”
Lex Fridman
I mean, if it’s possible to break out of the echo chambers, so to understand other people, other perspectives. I’ve seen that in wartime when there’s really strong divisions to understanding paves the way for peace and for love between people, because there’s a lot of incentive in war to have very narrow and shallow conceptions of the world. Different truths on each side. So bridging that, that’s what real understanding looks like, real truth looks like. And it feels like AI can do that better than humans do because humans really inject their biases into stuff.

You open the book, Life As No One Knows It: The Physics of Life’s Emergence, with the distinction between the materialists and the vitalists. So what’s the difference? Can you maybe define the two?
And a lot of what I talk about in the book, but also I think about a lot just professionally, is the nature of our definitions of what’s material and how science has come to invent the concept of matter. And that some of those things actually really are inventions that happened in a particular time in a particular technology that could learn about certain patterns and help us understand them, and that there are some patterns we still don’t understand. And if we knew how to measure those things or we knew how to describe them in a more rigorous way, we would realize that the material world matter has more properties than we thought that it did. One of those might be associated with the thing that we call life. Life could be a material property and still have a lot of the features that the vitalists thought were mysterious.
So we didn’t really have to worry about the fact that my cup is heavy and the air is light. The same laws describe them if we have the right material properties to talk about what those laws are actually interacting with. And so I think the issue with life is we don’t know how to think about information in a material way, and so we haven’t been able to build a unified description of what life is or the kind of things that evolution builds because we haven’t really invented the right material concept yet.
And then you can go to chemical system. I don’t think that’s good either. I think there’s a confusion because life emerges in chemistry that life is chemical. I don’t think life is chemical. I think life emerges in chemistry because chemistry is the first thing the universe builds where it cannot exhaust all the possibilities, because the combinatorial space of chemistry is too large.
So chemical space is huge, and I think it’s really important to recognize that because if you want to ask a question of why does life emerge in chemistry, well, life emerges in chemistry because life is the physics of how the universe selects what gets to exist. And those things get created along historically contingent pathways and memory and all the other stuff that we can talk about, but the universe has to actually make historically contingent choices in chemistry because it can’t exhaust all possible molecules.
And so we focus so much on these individuals that are these short temporal moments in this larger causal structure that actually is the life on our planet, and I think that’s why these definitions break down because they’re not general enough, they’re not universal enough, they’re not deep enough, they’re not abstract enough to actually capture that regularity.
And so what I’m getting at with this is I think that living objects are actually huge. They’re some of the biggest structures in the universe, but they are not big in space. They’re big in time. And we actually can’t resolve that feature. We don’t interact with it on a regular basis, so we see them as these fleeting things that have this really short temporal clock time without seeing how large they are. When I’m saying time here, really, the way that people could picture it is in terms of causal structure. So if you think about the history of the universe to get to you and you imagine that that entire history is you, that is the picture I have in my mind when I look at every living thing.
And so you and I are close in this temporal structure, but we’re so close because we’re really big and we only are very different and the most recent moments in the time that’s embedded in us. It’s hard to use words to visualize what’s in minds. I have such a hard time with this sometimes. Actually, I was thinking on the way over here, I was like, you have pictures in your brain and then they’re hard to put into words. But I realized I always say I have a visual, but it’s not actually I have a visual. I have a feeling, because oftentimes I cannot actually draw a picture in my mind for the things that I say, but sometimes they go through a picture before they get to words. But I like experimenting with words because I think they help paint pictures.
And really the question is, why can life generate so much order? And we don’t have a physics to describe that. And it’s interesting, generations of physicists have thought about this problem. Oftentimes, it’s like when people are retiring, they’re like, “Oh, now I can work on life.” Or they’re more senior in their career and they’ve worked on other more traditional problems. And there’s still a lot of impetus in the physics community to think that non-equilibrium physics will explain life. But I think that’s not the right approach. I don’t think ultimately the solution to what life is there, and I don’t really think entropy has much to do with it unless it’s entirely reformulated.
And I think it will radically fail in the longterm at describing reality at its more basal levels. But I’m not saying there’s a base, I don’t think that reality has a ground, and I don’t think there’s a theory of everything, but I think there are better theories, and I think there are more explanatory theories, and I think we can get to something that explains much more than the current laws of physics do.
So we typically define fundamental right now in terms of the smallest indivisible units of matter. So again, you have to have a definition of what you think material is and matter is, but right now what’s fundamental are elementary particles. And we think they’re fundamental because we can’t break them apart further. And obviously, we have theories like string theory that if they’re right would replace the current description of what’s the most fundamental thing in our universe by replacing with something smaller. But we can’t get to those theories because we’re technologically limited. And so if you look at this from a historical perspective and you think about explanations changing as physical systems like us learn more about the reality in which they live, we once considered atoms to be the most fundamental thing. And it literally comes from the word indivisible. And then we realized atoms had substructure because we built better technology, which allowed us to “See the world better” and resolve smaller features of it.
And then we built even better technology, which allowed us to see even smaller structure and get down to the standard model particles. And we think that there might be structure below that, but we can’t get there yet with our technology. So what’s fundamental, the way we talk about it in current physics is not actually fundamental, it’s the boundaries of what we can observe in our universe, what we can see with our technology. And so if you want to build a theory that’s about us and about what’s inside the universe that we can observe, not what’s at the boundary of it, you need to talk about objects that are in the universe that you can actually break apart to smaller things. So I think the things that are fundamental are actually the constructed objects.
They’re the ones that really exist, and you really understand their properties because you know how the universe constructed them because you can actually take them apart. You can understand the intrinsic laws that built them. But the things that the boundary are just at the boundary, they’re evolving with us, and we’ll learn more about that structure as we go along. But really, if we want to talk about what’s fundamental inside our universe, we have to talk about all these things that are traditionally considered emergent, but really just structures in time that have causal histories that constructed them and are really actually what our universe is about.
And so that sounds very abstract, but you can just think of a chemical reaction can’t happen if there’s not a catalyst, for example. Or a baby can’t be born if there wasn’t a parent. So there’s a lot of causal contingency that’s necessary for certain things to happen. So you think about this sort of unconstrained random system, there’s nothing that reinforces the existence of other things. So those sort of resources just get washed out in all of these different structures and none of them exist again, or they’re not very complicated if they’re in high abundance.
And some random events allow some things to start reinforcing the existence of a small subset of objects. And if they can do that, just molecules basically recognizing each other and being able to catalyze certain reactions. There’s this kind of transition point that happens where, unless you get a self-reinforcing structure, something that can maintain its own existence, it actually can’t cross this boundary to make any objects in high abundance without having this sort of past history that it’s carrying with us and maintaining the existence of that past history. And that boundary point where objects can’t exist unless they have the selection and history in them, is what we call the origin of life.
And pretty much everything beyond that boundary is holding on for dear life to all of the causation and causal structure that’s basically put it there, and it’s carving its way through this possibility space into generating more and more structure. And that’s when you get the open-ended cascade of evolution. But that boundary point is really hard to cross. And then what happens when you cross that boundary point and the way objects come into existence is also really fascinating dynamics, because as things become more complex, the assembly index increases. I can explain all these things. Sorry. You can tell me what you want to explain or what people will want to hear. This… Sorry, I have a very vivid visual in my brain and it’s really hard to articulate it.
Lee has a beautiful example of this actually in molybdenum. It’s like the first non-organic autocatalytic set. It’s a self-reproducing molybdenum ring. But it’s like molybdenum. And basically if you look at the molybdenum, it makes a huge molybdenum ring. I don’t remember exactly how big it is. It might be like 150 molybdenum atoms or something. But if you think about the configuration space of that object, it’s exponentially large how many possible molecules. So why does the entire system collapse on just making that one structure? If you start from molybdenum atoms that are maybe just a couple of them stuck together. And so what they see in this system is there’s a few intermediate stages. So there’s some random events where the chemistry comes together and makes these structures. And then once you get to this very large one, it becomes a template for the smaller ones. And then the whole system just reinforces its own production.
And so you have to have some kind of symmetry breaking where you go from these chemistries that seem entirely equivalent, to only having one chemistry takeover is the dominant form. And for a long time, I had been really… I actually did my PhD on the origin of chirality. I was working on it as a symmetry breaking problem in physics. This is how I got started in the origin of life. And then I left it for a long time because I thought it was one of the most boring problems in the origin of life, but I’ve come back to it. I think there’s something really deep going on here related to this combinatorial explosion of the space of possibilities. But just to get to that point, this feature of this handedness has been the main focus. But people take for granted the existence of chiral molecules at all, that this property of having a handedness, and they just assume that it’s just a generic feature of chemistry.
But if you actually look at molecules, if you look at chemical space, which is the space of all possible molecules that people can generate, and you look at small molecules, things that have less than about seven to 11 heavy atoms. So things that are not hydrogen, almost every single molecule in that space is achiral, like doesn’t have a chiral center. So it would be like a spoon. A spoon doesn’t have, it’s the same as its mirror image. It’s not like a hand that’s different than its mirror image. But if you get to this threshold boundary, above that boundary, almost every single molecule is chiral.
So you go from a universe where almost nothing has a mirror image form, there’s no mirror image universe of possibilities to this one where every single structure has pretty much a mirror image version. And what we’ve been looking at in my lab is that, it seems to be the case that the origin of life transition happens around the time when you start accumulating, you push your molecules to a large enough complexity that chiral molecules become very likely to form. And then there’s a cascade of molecular recognition where chiral molecules can recognize each other. And then you get this sort of autocatalytic feedback and things self-reinforcing.
And it also has to do with this transition in assembly, this transition in possibility spaces, because I think there’s something really fundamental going on at this boundary, that you don’t really need to go that far into chemical space to actually see life in terms of this depth in time, this depth in symmetries of objects, in terms of chiral symmetries or this assembly structure. But getting past this boundary that’s not very deep in that space requires life. It’s a really weird property, and it’s really weird that so many abrupt things happen in chemistry at that same scale.
And then it’s interesting when you get to societies like human societies, that we invent even better technologies of seeing, like telescopes and microscopes, which allow us to see deeper into the universe or at smaller scales. So I think that’s pretty profound, the way that site has transformed the ability of life to literally see the reality in which it’s existing in. I think consciousness is also obviously deeply interesting. I’ve gotten kind of obsessed with octopus. They’re just so weird. And the fact that they evolved complex nervous systems kind of independently seems very alien.
Standard physics would say that all of that complexity traces back to the infinitesimal deviations and the initial state of the universe that there was some order there. I find that deeply unsatisfactory. And what assembly theory says that’s very different is that, the universe is basically constructing itself, and when you get to these combinatorial spaces like chemistry, where the space of possibilities is too large to exhaust them all, you can only construct things along historically contingent paths, like you basically have causal chains of events that happen to allow other things to come into existence.
And that this is the way that complex objects get formed, is basically on scaffolding on the past history of objects, making more complex objects, making more complex objects. That idea in itself is easy to state and simple, but it has some really radical implications as far as what you think is the nature of the physics that would describe life. And so what assembly theory does formally is try to measure the boundary in the space of all things that chemically could exist. For example, like all possible molecules, where’s the boundary above which we should say these things are too complex to happen outside of an evolutionary chain of events, outside of selection. And we formalize that with two observables. One of them is the copy number, the object. So…
And what Lee’s been able to show in the lab with his team is that for organic chemistry, it’s about 15 steps. And then you only see molecules that the only molecules that we observe that are past that threshold are ones that are in life. And in fact, one of the things I’m trying to do with this idea of trying to actually quantify the origin of life as a transition in… A phase transition and assembly theory is actually be able to explain why that boundary is where because I think that’s actually the boundary that life must cross.
The idea of going back to this thing we were talking about before about these structures that can reinforce their own existence and move past that boundary, 15 seems to be that boundary in chemical space. It’s not a universal number. It will be different for different assembly spaces, but that’s what we’ve experimentally validated so far. And then-
And the size of each layer is growing exponentially. What you’re talking about, if you want to look at the long way of getting to an object, as I’m increasing the assembly index of an object, I’m moving deeper and deeper into an exponentially growing space. And it’s actually also the case that the typical path to get to that object is also exponentially growing with respect to the assembly index.
And so, if you want to try to make a more and more complex object and you want to do it by a typical path, that’s actually an exponentially receding horizon. And so most objects that come into existence have to be causally very similar to the things that exist because close by in that space, and they can actually get to it by an almost shortest path for that object.
And that’s true. We do see things that do exist competing to continue to exist. But if you think about this space of possibilities and each time the universe generates a new structure or an object that exists, generates a new structure along this causal chain. It’s generating something that exists that never existed before.
And each time that we make that kind of decision, we’re excluding a huge piece of possibilities. And so actually, as this process of increasing assembly index, it’s not just that the space that these objects exist in is exponentially growing, but there are objects in that space that are exponentially receding away from us. They’re becoming exponentially less and less likely to ever exist. And so, existence excludes a huge number of things.
And deterministic structures emerge by things that can causally reinforce themselves and maintain persistence over time. And so, we are some of the most deterministic things in the universe. And so, we can generate very regular structure and we can generate new structure along a particular lineage. But the possibility space at the tips, the things we can generate next is really huge.
There’s some stochasticity in what we actually instantiate as the next structures that get built in the biosphere. It’s not completely deterministic because the space of future possibilities is always larger than the space of things that exist now.
Language is another one where the space of possible configurations of the 26 letters of the English alphabet is astronomically large, but we use with very high regularity, certain structures. And then we associate meaning to them because of the regularity of how much we use them. Meaning is an emergent property of the causation and the objects and how often they recur and what the relationship of the recurrence is to other objects.
And I do this all the time, and you have to do it with the kind of work that I do because if you want to discover an abstraction, like some keep concept that we don’t understand yet, it means we don’t have the language. And so, the words that we have are inadequate to describe the things.
This is why we’re having a hard time talking about assembly theory because it’s a newly emerging idea. And so, I’m constantly playing with words in different ways to try to convey the meaning that is actually behind the words, but it’s hard to do.
But the sort of visual that gets built in my brain about that is the structure that we’re building on this planet is packing more and more time in this very small volume of space because our planet hasn’t changed its physical size in 4 billion years, but there’s a ton of causation and recursion and time, whatever word you want to use, information packed into this.
And I think this is also embedded in the virtualization of our technologies or the abstraction of language and all of these things. These things that seem really abstract are just really deep in time. And so, what that looks like is you have a planet that becomes increasingly virtualized. And so it’s getting bigger and bigger in time, but not really expanding out in space. And the rest of space is moving away from it. Again, it’s a exponentially receding horizon. And I’m just not sure how far into this evolutionary process something gets if it can ever see that there’s another such structure out there.
What I mean by virtual here is virtual reality for me, things that appear virtual, appear abstract are just things that are very deep in time in the structure of the things that we are. If you think about you as a 4 billion year old object, the things that are a part of you, like your capacity to use language or think abstractly or have mathematics are just very deep temporal structures. That’s why they look like they’re informational and abstract is because they’re existing in this temporal part of you, but not necessarily spatial part.
As typical, I don’t think that’s actually the right physics, but I think something about that idea as I do with all ideas is partially correct. And Freeman Dyson also had this amazing paper about how long life could persist in a universe that was exponentially expanding. And his conception was if you imagine analog life form, it could run slower and slower and slower and slower and slower as a function of time. And so, it would be able to run indefinitely, even against an exponentially expanding universe because it would just run exponentially slower.
And so, I guess part of what I’m doing in my brain is putting those two things together along with this idea that, if you imagine with our technology, we’re now building virtual realities, things we actually call virtual reality. Which required four billions years of history and a whole bunch of data to basically embed them in a computer architecture. Now you can put an Oculus headset on and think that you’re in this world.
And what you really are embedded in is in a very deep temporal structure. And so, it’s huge in time, but it’s very small in space. And you can go lots of places in the virtual space, but you’re still stuck in your physical body and sitting in the chair. And so, part of it is it might be the case that sufficiently evolved biospheres virtualize themselves. And they internalize their universe in their temporal causal structure, and they close themselves off from the rest of the universe.
I live in these really abstract spaces most of the time. But there’s also this issue of extinction. Extinction events are basically pinching off an entire causal structure. The one of these… I’m going to call them time crystals, I don’t know what, but there’s these very large objects in time. Pinching off that whole structure from the rest of it. And so it’s like, if you imagine that same thing in the universe, I once thought that sufficiently advanced technologies would look like black holes.
If I get to a more grounded discussion, what I’m really interested in doing is trying to solve the origin of life so we can understand how likely life is out there. I think that the problem of discovering alien life and solving the origin of life are deeply coupled and in fact are one in the same problem, and that the first contact with alien life will actually be in an origin of life experiment. But that part I’m super interested in.
And then there’s this other feature that I think about a lot, which is our own technological phase of development as what is this phase in the evolution of life on a planet? If you think about a biosphere emerging on a planet and evolving over billions of years and evolving into a technosphere. When a technosphere can move off planet and basically reproduce itself on another planet, now you have biospheres reproducing themselves. Basically they have to go through technology to do that.
And so, there are ways of thinking about the nature of intelligent life and how it spreads in that capacity that I’m also really excited about and thinking about. And all of those things for me are connected. We have to solve the origin of life in order for us to get off planet because we basically have to start life on another planet. And we also have to solve the origin life in order to recognize other alien intelligence. All of these things are literally the same problem.
And so, I have this really talented undergrad student that’s basically building a model of alien communication based on fireflies. One of my colleagues, Orit Peleg, is she’s totally brilliant. But she goes out with GoPro cameras and films in high resolution, all these firefly flickering. And she has this theory about how their signaling evolved to maximally differentiate the flickering pattern. She has a theory basically that predicts this species should flash like this. If this one’s flashing like this, other one’s going to do it at a slower rate so that they can distinguish each other living in the same environment.
And so this undergrad’s building this model where you have a pulsar background of all these giant flashing sources in the universe. And an alien intelligence wants to signal it’s there so it’s flashing a firefly. And I like the idea of thinking about non-human aliens so that was really fun.
And Stewart Brand has this great infographic about the layers of human society. And I think it starts with the natural sciences and physics at the bottom, and it goes through all these layers and it’s economics. And then fashion is at the top, is the fastest moving part of human culture. And I think I really like that because it’s so dynamic and so short and it’s temporal longevity. Contrasted with studying the laws of physics, which are the deep structure reality that I feel like bridging those scales tells me much more about the structure of the world that I live in.
What do you mean it doesn’t have function?
I just like to do it because a confidence thing, it’s about embodying the person that I want to be and about owning that person. Then the way that people interact with that person is very different than if I wasn’t using that attribute as part of… Obviously, that’s influenced by the society I live and what’s aesthetically pleasing things. But it’s interesting to be able to turn that around and not have it necessarily be about the aesthetics, but about the power dynamics that the aesthetics create.
They have a different ontology to them. They’re physical things and they carry causation and they can create meaning, but they’re not what we think they are. Also, the internal representations in our mind, the things I’m seeing about this room are probably… They’re small projection of the things that are actually in this room. I think we have such a difficult time moving past the way that we build representations in the mind and the way that we structure our language to realize that those are approximations to what’s out there and they’re fluid, and we can play around with them and we can see deeper structure underneath them that I think we’re missing a lot.
It only happens in some of them. I think one of the reasons that we feel like the universe is computational is because it’s so easy for us as things that have the theory of computation in our minds. Actually, in some sense it might be related to the functioning of our minds and how we build languages to describe the world and sets of relations to describe the world. But it’s easy for us to go out into the world and build computers and then we mistake our ability to do that with assuming that the world is computational. I’ll give you a really simple example. This one came from John Conway. I one time had a conversation with him, which was really delightful. He was really fun. But he was pointing out that if you string lights in a barn, you can program them to have your favorite one dimensional CA and you might even be able to make them do a be capable of universal computation. Is universal computation a feature of the string lights?
The point, I guess, I’m making about having a question is no matter what slice of reality you take, what regularity of nature you’re going to try to describe, there will be an abstraction that unifies that structure of reality, hopefully. That will have a fundamental layer to it. You have to explain something in terms of something else. If I want to explain life, for example, then my fundamental description of nature has to be something I think that has to do with time being fundamental. But if I wanted to describe, I don’t know the interactions of matter and light, I have elementary particles be fundamental. If I want to describe electricity and magnetism in the 18 hundreds, I have to have waves be fundamental. Right? You are in quantum mechanics. It’s a wave function that’s fundamental because the explanatory paradigm of your theory. I guess I don’t know what problem saying computation is fundamental solves.
I think that’s a really different approach than saying, “Consciousness is this thing we all feel and experience about things.” I would want to understand irregularities associated with that and build a deeper structure underneath that and build into it. I wouldn’t want to assume that thing and that I understand that thing, which is usually how I see people talk about it,
I really love David Deutsch’s conception of universal explainers, and that’s related to theory of universal computation. I think there’s some transition that happens there. But maybe to describe that a little bit better, what I can also say is what intelligence is in this framework. You have these objects that are large in time. They were selected to exist by constraining the possible space of objects to this particular, all of the matter is funneled into this particular configuration of object over time.
These objects arise through selection, but the more selection that you have embedded in you, the more possible selection you have on your future. Selection and evolution, we usually think about in the past sense where selection happened in the past, but objects that are high density configurations of matter that have a lot of selection in them are also selecting agents in the universe. They actually embody the physics of selection and they can select on possible futures. I guess what I’m saying with respect to consciousness and the experience we have is that something very deep about that structure and the nature of how we exist in that structure that has to do with how we’re navigating that space and how we generate that space and how we continue to persist in that space.
Large language models are interesting because they don’t feel as static. They’re very dynamic. But if you think about language in the way I was describing before, as language is this very large in time structure. Before it had been something that was distributed over human brains as a dynamic structure. Occasionally, we store components of that very large dynamic structure in books or in written language. Now, we can actually store the dynamics of that structure in a physical artifact, which is a large language model. I think about it almost like the evolution of genomes in some sense, where there might’ve been really primitive genes in the first living things and they didn’t store a lot of information or they were really messy.
Then by the time you get to the eukaryotic cell, you have this really dynamic genetic architecture that’s read writable and has all of these different properties. I think large language models are kind of like the genetic system for language in some sense, where it’s allowing an archiving that’s highly dynamic. I think it’s very paradoxical to us because obviously in human history, we haven’t been used to conversing anything that’s not human. But now we can converse basically with a crystallization of human language in a computer that’s a highly dynamic crystal because it’s a crystallization in time of this massive abstract structure that’s evolved over human history and is now put into a small device.
And so I think we really have to think about is it a level shift or is it we’re enhancing certain kinds of capabilities humans have in the same way that we enhanced eyesight by making telescopes and microscopes? Are we enhancing capabilities we have into technologies and the entire global ecosystem is getting more intelligent? Or is it really that we’re building some super machine in a box that’s going to be smart and kill everybody? It’s not even a science fiction narrative. It’s a bad science fiction narrative. I just don’t think it’s actually accurate to any of the technologies we’re building or the way that we should be describing them. It’s not even how we should be describing ourselves.
I think one thing that’s good is when people are talking about things in different ways, it makes us think about them. And also, when things are existentially threatening, we want to pay attention to those. But the ways that they’re existentially threatening and the ways that we’re experiencing existential trauma, I don’t think that we’re really going to understand for another century or two, if ever. And I certainly think they’re not the way that we’re describing them now.
So even if you look at the division in American politics or something, for example. It’s important that there’s multiple sides that are arguing with each other because that’s actually how you resolve society’s issues. It’s not like a bad feature. I think some of the extreme positions and the way people talk about are maybe not ideal, but that’s how societies solve problems. What it looks like for an individual is really different than the societal level outcomes and the fact that there is… I don’t want to call it cognition or computation. I don’t know what you call it, but there is a process playing out in the dynamics of societies that we are all individual actors in, and we’re not part of that. It requires all of us acting individually, but this higher level structure is playing out some things and things are getting solved for it to be able to maintain itself. And that’s the level that our technologies live at. They don’t live at our level. They live at the societal level, and they’re deeply integrated with the social organism, if you want to call it that.
And so I really get upset when people talk about the species of artificial intelligence. I’m like, you mean we live in an ecosystem of all these intelligent things and these animating technologies that were in some sense helping to come alive. We are generating them, but it’s not like the biosphere eliminated all of its past history when it invented a new species. All of these things get scaffolded, and we’re also augmenting ourselves at the same time that we’re building technologies. I don’t think we can anticipate what that system’s going to look like.
And so the origin of life is happening again right now on this planet in the technosphere with the way that our planet is undergoing another transition. Just like at the origin of life, when geochemistry transitioned to biology, which is the global… For me, it was a planetary scale transition. It was a multiscale thing that happened from the scale of chemistry all the way to planetary cycles. It’s happening now, all the way from individual humans to the internet, which is a global technology and all the other things. There’s this multiscale process that’s happening and transitioning us globally, and it’s a dramatic transition. It’s happening really fast and we’re living in it.
So death is a way to make room in the universe for other things to exist that wouldn’t be able to exist otherwise. So if the universe over its entire temporal history wants to maximize the number of things… Wants is a hard word, maximize is a hard word, all these things are approximate, but wants to maximize the number of things that can exist, the best way to do it is to make recursively embedded stacked objects like us that have a lot of structure and a small volume of space. And to have those things turn over rapidly so you can create as many of them as possible.
So I think there is something about age and your ability to learn and how much of the world you can see that’s really important over a human lifespan, but also over the lifespan of societies. And so I don’t know how big the frontier is. I don’t actually think it has a limit. I don’t believe in infinity as a physical thing, but I think as a receding horizon, I think because the universe is getting bigger, you can never know all of it.
And then that gives you a space to operate in, and that’s your horizon where your free will can operate, and your free will can’t be instantaneous. So for example, I’m sitting here talking to you right now. I can’t be in the UK and I can’t be in Arizona, but I could plan, I could execute my free will over time because free will is a temporal feature of life, to be there tomorrow or the next day if I wanted to.
And I love the shock value that people have, that immediate moment of recognizing that there’s something beyond the way that they thought about things before. And being able to deliver that to people, I think is one of the biggest joys that I have, is just… Maybe it’s that sense of mystery to share that there’s something beyond the frontier of how we understand and we might be able to see it.

Introduction
Sara Walker
You have an origin of life event. It evolves for 4 billion years, at least on our planet. It evolves a technosphere. The technologies themselves start having this property we call life, which is the phase we’re undergoing now. It solves the origin of itself and then it figures out how that process all works, understands how to make more life, and then can copy itself onto another planet so the whole structure can reproduce itself.

Definition of life
You open the book, Life As No One Knows It: The Physics of Life’s Emergence, with the distinction between the materialists and the vitalists. So what’s the difference? Can you maybe define the two?
Sara Walker
I think the question there is about whether life can be described in terms of matter and physical things, or whether there is some other feature that’s not physical that actually animates living things. So for a long time, people maybe have called that a soul. It’s been really hard to pin down what that is. So I think the vitalist idea is really that it’s a dualistic interpretation that there’s sort of the material properties, but there’s something else that animates life that is there when you’re alive and it’s not there when you’re dead. And materialists don’t think that there’s anything really special about the matter of life and the material substrates that life is made out of, so they disagree on some really fundamental points.

Is there a gray area between the two? Maybe all there is is matter, but there’s so much we don’t know that it might as well be magic. Whatever that magic that the vitalists see, meaning there’s just so much mystery that it’s really unfair to say that it’s boring and understood and as simple as “physics.”

Sara Walker
Yeah, I think the entire universe is just a giant mystery. I guess that’s what motivates me as a scientist. And so oftentimes, when I look at open problems like the nature of life or consciousness or what is intelligence or are there souls or whatever question that we have that we feel like we aren’t even on the tip of answering yet, I think we have a lot more work to do to really understand the answers to these questions. So it’s not magic, it’s just the unknown. And I think a lot of the history of humans coming to understand the world around us has been taking ideas that we once thought were magic or supernatural and really understanding them in a much deeper way that we learn what those things are. And they still have an air of mystery even when we understand them. There’s no bottom to our understanding.

So do you think the vitalists have a point that they’re more eager and able to notice the magic of life?

Sara Walker
I think that no tradition, vitalists included, is ever fully wrong about the nature of the things that they’re describing. So a lot of times when I look at different ways that people have described things across human history, across different cultures, there’s always a seed of truth in them. And I think it’s really important to try to look for those, because if there are narratives that humans have been telling ourselves for thousands of years, for thousands of generations, there must be some truth to them. We’ve been learning about reality for a really long time and we recognize the patterns that reality presents us. We don’t always understand what those patterns are, and so I think it’s really important to pay attention to that. So I don’t think the vitalists were actually wrong.

And a lot of what I talk about in the book, but also I think about a lot just professionally, is the nature of our definitions of what’s material and how science has come to invent the concept of matter. And that some of those things actually really are inventions that happened in a particular time in a particular technology that could learn about certain patterns and help us understand them, and that there are some patterns we still don’t understand. And if we knew how to measure those things or we knew how to describe them in a more rigorous way, we would realize that the material world matter has more properties than we thought that it did. One of those might be associated with the thing that we call life. Life could be a material property and still have a lot of the features that the vitalists thought were mysterious.
Lex Fridman
So we may still expand our understanding, what is incorporated in the category of matter, that will eventually incorporate such magical things that the vitalists have noticed, like life?

Sara Walker
Yeah. I always like to use examples from physics, so I’ll probably do that. It’s my go-to place. But in the history of gravitational physics, for example, in the history of motion, when Aristotle came up with his theories of motion, he did it by the material properties he thought things had. So there was a concept of things falling to earth because they were solid-like and things raising to the heavens because they were air-like and things moving around the planet because they were celestial-like. But then we came to realize that, thousands of years later and after the invention of many technologies that allowed us to actually measure time in a mechanistic way and track planetary motion and we could roll balls down inclined planes and track that progress, we realized that if we just talked about mass and acceleration, we could unify all motion in the universe in a really simple description.

So we didn’t really have to worry about the fact that my cup is heavy and the air is light. The same laws describe them if we have the right material properties to talk about what those laws are actually interacting with. And so I think the issue with life is we don’t know how to think about information in a material way, and so we haven’t been able to build a unified description of what life is or the kind of things that evolution builds because we haven’t really invented the right material concept yet.
Lex Fridman
So when talking about motion, the laws of physics appear to be the same everywhere out in the universe. You think the same is true for other kinds of matter that we might eventually include life in?

Sara Walker
I think life obeys universal principles. I think there is some deep underlying explanatory framework that will tell us about the nature of life in the universe and will allow us to identify life that we can’t yet recognize because it’s too different.

You’re right about the paradox of defining life. Why does it seem to be so easy and so complicated at the same time?
You’re right about the paradox of defining life. Why does it seem to be so easy and so complicated at the same time?
Sara Walker
All the classic definitions people want to use just don’t work. They don’t work in all cases. So Carl Sagan had this wonderful essay on definitions of life where I think he talks about aliens coming from another planet. If they saw earth, they might think that cars were the dominant life form because there are so many of them on our planet. Humans are inside them, and you might want to exclude machines. But any definition, classic biology textbook definitions, would also include them. He wanted to draw a boundary between these kind of things by trying to exclude them, but they were naturally included by the definitions people want to give. And in fact, what he ended up pointing out is that all of the definitions of life that we have, whether it’s life is a self-reproducing system or life eats to survive or life requires compartments, whatever it is, there’s always a counterexample that challenges that definition. This is why viruses are so hard or why fire is so hard. And so we’ve had a really hard time trying to pin down from a definitional perspective exactly what life is.

Yeah, you actually bring up the zombie-ant fungus. I enjoyed looking at this thing as an example of one of the challenges. You mentioned viruses, but this is a parasite. Look at that.

Did you see this in the jungle?
Did you see this in the jungle?
Lex Fridman
Infects ants. Actually, one of the interesting things about the jungle, everything is ephemeral. Everything eats everything really quickly. So if an organism dies, that organism disappears. It’s a machine that doesn’t have… I wanted to say it doesn’t have a memory or a history, which is interesting given your work on history in defining a living being. The jungle forgets very quickly. It wants to erase the fact that you existed very quickly.

Sara Walker
Yeah, but it can’t erase it. It’s just restructuring it. And I think the other thing that is really vivid to me about this example that you’re giving is how much death is necessary for life. So I worry a bit about notions of immortality and whether immortality is a good thing or not. So I have a broad conception that life is the only thing the universe generates that actually has even the potential to be immortal, but that’s as the sort of process that you’re describing where life is about memory and historical contingency and construction of new possibilities. But when you look at any instance of life, especially one as dynamic as what you’re describing, it’s a constant birth and death process. But that birth and death process is the way that the universe can explore what possibilities can exist. And not everything, not every possible human or every possible ant or every possible zombie ant or every possible tree, will ever live. So it’s an incredibly dynamic and creative place because of all that death.
Yeah, but it can’t erase it. It’s just restructuring it. And I think the other thing that is really vivid to me about this example that you’re giving is how much death is necessary for life. So I worry a bit about notions of immortality and whether immortality is a good thing or not. So I have a broad conception that life is the only thing the universe generates that actually has even the potential to be immortal, but that’s as the sort of process that you’re describing where life is about memory and historical contingency and construction of new possibilities.

This is a parasite that needs the ant. So is this a living thing or is this not a living thing?

It just pierces the ant.

Sara Walker
Right.
Right.
Lex Fridman
And I’ve seen a lot of this, by the way. Organisms working together in the jungle, like ants protecting a delicious piece of fruit. They need the fruit, but if you touch that fruit, the forces emerge. They’re fighting you. They’re defending that fruit to the death. Nature seems to find mutual benefits, right?

Sara Walker
Yeah, it does. I think the thing that’s perplexing for me about these kind of examples is effectively the ant’s dead, but it’s staying alive now because piloted by this fungus. And so that gets back to this thing that we’re talking about a few minutes ago about how the boundary of life is really hard to define. So anytime that you want to draw a boundary around something and you say, “This feature is the thing that makes this alive, or this thing is alive on its own,” there’s not ever really a clear boundary. And these kind of examples are really good at showing that because it’s like the thing that you would’ve thought is the living organism is now dead, except that it has another living organism that’s piloting it. So the two of them together are alive in some sense, but they’re now in this weird symbiotic relationship that’s taking this ant to its death.

Lex Fridman
So what do you do with that in terms of when you try to define life?
So what do you do with that in terms of when you try to define life?
Sara Walker
I think we have to get rid of the notion of an individual as being relevant. And this is really difficult because a lot of the ways that we think about life, like the fundamental unit of life is the cell, individuals are alive, but we don’t think about how gray that distinction is. So for example, you might consider self-reproduction to be the most defining feature of life. A lot of people do, actually. That’s one of these standard different definitions that a lot of people in my field like to use in astrobiology is life as a self-sustaining chemical system capable of Darwinian evolution, which I was once quoted as agreeing with, and I was really offended because I hate that definition. I think it’s terrible, and I think it’s terrible that people use it. I think every word in that definition is actually wrong as a descriptor of life.

So self-sustaining, chemical system, Darwinian evolution. What is self-sustaining? What’s so frustrating? Which aspect is frustrating to you, but it’s also those are very interesting words.
Sara Walker
Yeah, they’re all interesting words and together they sound really smart and they sound like they box in what life is. But you can use any of the words individually and you can come up with counterexamples that don’t fulfill that property. The self-sustaining one is really interesting, thinking about humans. We’re not self-sustaining dependent on societies. And so I find it paradoxical that it might be that societies, because they’re self-sustaining units, are now more alive than individuals are. And that could be the case, but I still think we have some property associated with life. That’s the thing that we’re trying to describe, so that one’s quite hard. And in general, no organism is really self-sustaining. They always require an environment, so being self-sustaining is coupled in some sense to the world around you. We don’t live in a vacuum, so that part’s already challenging.

And then you can go to chemical system. I don’t think that’s good either. I think there’s a confusion because life emerges in chemistry that life is chemical. I don’t think life is chemical. I think life emerges in chemistry because chemistry is the first thing the universe builds where it cannot exhaust all the possibilities, because the combinatorial space of chemistry is too large.
Lex Fridman
Well, but is it possible to have a life that is not a chemical system?
Well, but is it possible to have a life that is not a chemical system?

But wait, but you said that universe, the first thing it creates is chemistry.
But wait, but you said that universe, the first thing it creates is chemistry.
Sara Walker
Very precisely. It’s not the first thing it creates. Obviously, it has to make atoms first, but it’s the first thing. If you think about the universe originated, atoms were made in Big Bang nuclear synthesis, and then later in stars. And then planets formed and planets become engines of chemistry. They start exploring what kind of chemistry is possible. And the combinatorial space of chemistry is so large that even on every planet in the entire universe, you will never express every possible molecule. I like this example actually that Lee gave me, which is to think about Taxol. It has a molecular weight of about 853. It’s got a lot of atoms, but it’s not astronomically large. And if you try to make one molecule with that molecular formula and every three-dimensional shape you could make with that molecular formula, it would fill 1.5 universes in volume with one unique molecule. That’s just one molecule.

So chemical space is huge, and I think it’s really important to recognize that because if you want to ask a question of why does life emerge in chemistry, well, life emerges in chemistry because life is the physics of how the universe selects what gets to exist. And those things get created along historically contingent pathways and memory and all the other stuff that we can talk about, but the universe has to actually make historically contingent choices in chemistry because it can’t exhaust all possible molecules.
Lex Fridman
What kind of things can you create that’s outside the combinatorial space of chemistry? That’s what I’m trying to understand.

Sara Walker
Oh, if it’s not chemical. So I think some of the things that have evolved on our biosphere I would call as much alive as chemistry, as a cell, but they seem much more abstract. So for example, I think language is alive, or at least life. I think memes are. I think-

Life maybe. Maybe not alive, but actually I don’t know where I stand exactly on that. I’ve been thinking about that a little bit more lately. But mathematics too, and it’s interesting because people think that math has this Platonic reality that exists outside of our universe, and I think it’s a feature of our biosphere and it’s telling us something about the structure of ourselves. And I find that really interesting because when you would internalize all of these things that we noticed about the world, and you start asking, well, what do these look like? If I was something outside of myself observing these systems that all embedded in, what would that structure look like? And I think we look really different than the way that we talk about what we look like to each other.

I think it’s the fact that it’s open-ended in some sense. It’s another open-ended combinatorial space, and the recursive properties of it allow creativity to happen, which is what you see with the revolution in the last century with Gödel’s Theorem and Turing. And there’s clear places where mathematics notices holes in the universe.

Restricted to chemical. What about the third thing, which I think will be the hardest because you probably like it the most, is evolution or selection.
Sara Walker
Well, specifically it’s Darwinian evolution. And I think Darwinian evolution is a problem. But the reason that that definition is a problem is not because evolution is in the definition, but because the implication that most people would want to make is that an individual is alive. And the evolutionary process, at least the Darwinian evolutionary process, most evolutionary processes, they don’t happen at the level of individuals. They happen at the level of population. So again, you would be saying something like what we saw with the self-sustaining definition, which is that populations are alive, but individuals aren’t because populations evolve and individuals don’t. And obviously maybe you are alive because your gut microbiome is evolving. But Lex is an entity right now is not evolving by canonical theories of evolution. In assembly theory, which is attempting to explain life, evolution is a much broader thing.

Lex Fridman
It’s fun.
It’s fun.
Sara Walker
Yeah, it is fun. It is really fun. And actually I do think it’s useful in the sense that when you see the ways that they all break down, you either have to keep forcing in your conception of life you want to have, or you have to say, “All these definitions are breaking down for a reason. Maybe I should adopt a more expansive definition that encompasses all the things that I think and are life.” And so for me, I think life is the process of how information structures matter over time and space, and an example of life is what emerges on a planet and yields an open-ended cascade of generation of structure and increasing complexity. And this is the thing that life is. And any individual is just a particular instance of these lineages that are structured across time.

And this is the thing that life is. And any individual is just a particular instance of these lineages that are structured across time.
And so we focus so much on these individuals that are these short temporal moments in this larger causal structure that actually is the life on our planet, and I think that’s why these definitions break down because they’re not general enough, they’re not universal enough, they’re not deep enough, they’re not abstract enough to actually capture that regularity.
Lex Fridman
Because we’re focused on that little ephemeral thing and call it human life?
Because we’re focused on that little ephemeral thing and call it human life?

I think we’re missing most of what we are. One of the issues… I’ve been thinking about this really viscerally lately. It’s weird when you do theoretical physics, because I think it literally changes the structure of your brain and you see the world differently, especially when you’re trying to build new abstractions.

I think you’re always on the edge of it, but I think what is amazing about being a scientist and trying to do things rigorously is it keeps your sanity. So I think if I wasn’t a theoretical physicist, I would be probably not sane. But what it forces you to do is you have to hold yourself to the fire of these abstractions in my mind have to really correspond to reality. And I have to really test that all the time. And so I love building new abstractions and I love going to those incredibly creative spaces that people don’t see as part of the way that we understand the world now. But ultimately, I have to make sure that whatever I’m pulling from that space is something that’s really usable and really relates to the world outside of me. That’s what science is.

So we were talking about what we’re missing when we look at a small stretch of time in a small stretch of space.
So we were talking about what we’re missing when we look at a small stretch of time in a small stretch of space.
Sara Walker
Yeah, so the issue is we evolve perception to see reality a certain way. So for us, space is really important and time feels fleeting. And I had a really wonderful mentor, Paul Davies, most of my career. And Paul’s amazing because he gives these little seed thought experiments all the time. Something he used to ask me all the time was when I was a postdoc, this is a random tangent, but was how much of the universe could be converted into technology if you were thinking about long-term futures and stuff like that. And it’s a weird thought experiment, but there’s a lot of deep things there. And I do think a lot about the fact that we’re really limited in our interactions with reality by the particular architectures that we evolved, and so we’re not seeing everything. And in fact, our technology tells us this all the time because it allows us to see the world in new ways by basically allowing us to perceive the world in ways that we couldn’t otherwise.

And so what I’m getting at with this is I think that living objects are actually huge. They’re some of the biggest structures in the universe, but they are not big in space. They’re big in time. And we actually can’t resolve that feature. We don’t interact with it on a regular basis, so we see them as these fleeting things that have this really short temporal clock time without seeing how large they are. When I’m saying time here, really, the way that people could picture it is in terms of causal structure. So if you think about the history of the universe to get to you and you imagine that that entire history is you, that is the picture I have in my mind when I look at every living thing.

So if we could see time, what would the world look like? You’re saying you’ll be able to see everything that an object has been, every step of the way that led to this current moment, and all the interactions that require to make that evolution happen.

Sara Walker
But I don’t think of them as separate. They’re very integrated with the structure that generated them. So you can almost imagine it like time is constantly bifurcating and it’s generating new structures, and these new structures are locally constructing the future. And so things like you and I are very close together in time because we didn’t diverge very early in the history of universe. It’s very recent. And I think this is one of the reasons that we can understand each other so well and we can communicate effectively, and I might have some sense of what it feels like to be you. But other organisms bifurcated from us in time earlier. This is just the concept of phylogeny. But if you take that deeper and you really think about that as the structure of the physics that generates life and you take that very seriously, all of that causation is still bundled up in the objects we observe today.

And so you and I are close in this temporal structure, but we’re so close because we’re really big and we only are very different and the most recent moments in the time that’s embedded in us. It’s hard to use words to visualize what’s in minds. I have such a hard time with this sometimes. Actually, I was thinking on the way over here, I was like, you have pictures in your brain and then they’re hard to put into words. But I realized I always say I have a visual, but it’s not actually I have a visual. I have a feeling, because oftentimes I cannot actually draw a picture in my mind for the things that I say, but sometimes they go through a picture before they get to words. But I like experimenting with words because I think they help paint pictures.
Lex Fridman
It’s, again, some kind of compressed feeling that you can query to get a sense of the bigger visualization that you have in mind. It’s just a really nice compression. But I think the idea of this object that in it contains all the information about the history of an entity that you see now, just trying to visualize that is pretty cool. Obviously, the mind breaks down quickly as you step seconds and minutes back in time.
It’s, again, some kind of compressed feeling that you can query to get a sense of the bigger visualization that you have in mind. It’s just a really nice compression.

Lex Fridman
I guess it’s just a gigantic object we’re supposed to be thinking about.
I guess it’s just a gigantic object we’re supposed to be thinking about.
Sara Walker
Yeah, I think so. And I think this is one of the reasons that we have such an ability to abstract as humans because we are so gigantic that the space that we can go back into is really large. So the more abstract you’re going, the deeper you’re going in that space.
Yeah, I think so. And I think this is one of the reasons that we have such an ability to abstract as humans because we are so gigantic that the space that we can go back into is really large. So the more abstract you’re going, the deeper you’re going in that space.
Lex Fridman
But in that sense, aren’t we fundamentally all connected?
But in that sense, aren’t we fundamentally all connected?
Sara Walker
Yes. And this is why the definition of life cannot be the individual. It has to be these lineages because they’re all connected, they’re interwoven, and they’re exchanging parts all the time.
Yes. And this is why the definition of life cannot be the individual. It has to be these lineages because they’re all connected, they’re interwoven, and they’re exchanging parts all the time.
Lex Fridman
Yeah, so maybe there are certain aspects of those lineages that can be lifelike. They can be characteristics. They can be measured with the sunbeam theory that have more or less life, but they’re all just fingertips of a much bigger object.

Sara Walker
Yeah, I think life is very high dimensional. In fact, I think you can be alive in some dimensions and not in others. If you could project all the causation that’s in you, in some features of you, very little causation is required, very little history. And in some features, a lot is. So it’s quite difficult to take this really high-dimensional, very deep structure and project it into things that we really can understand and say, “This is the one thing that we’re seeing,” because it’s not one thing.

Lex Fridman
It’s funny we’re talking about this now and I’m slowly starting to realize, one of the things I saw when I took Ayahuasca, afterwards actually, so the actual ceremony is four or five hours, but afterwards you’re still riding whatever the thing that you’re riding. And I got a chance to afterwards hang out with some friends and just shoot the shit in the forest, and I could see their faces. And what was happening with their faces and their hair is I would get this interesting effect. First of all, everything was beautiful and I just had so much love for everybody, but I could see their past selves behind them. I guess it’s a blurring effect of where if I move like this, the faces that were just there are still there and it would just float like this behind them, which will create this incredible effect. But another way to think about that is I’m visualizing a little bit of that object of the thing they were just a few seconds ago. It’s a cool little effect.

Lex Fridman
And now it’s giving it a bit more profundity to the effect that was just beautiful aesthetically, but it’s also beautiful from a physics perspective because that is a past self. I get a little glimpse at the past selves that they were. But then you take that to its natural conclusion, not just a few seconds ago, but just to the beginning of the universe. And you could probably get to that-

Sara Walker

Yeah.

You mentioned just the technosphere, and you also wrote that the most, the live thing on this planet is our technosphere. Why is the technology we create a kind of life form? Why are you seeing it as life?

Sara Walker
Because it’s creative. But with us, obviously. Not independently of us. And also because of this lineage view of life. And I think about life often as a planetary scale phenomena because the natural boundary for all of this causation that’s bundled in every object in our biosphere. And so for me, it’s just the current boundary of how far life on our planet has pushed into the things that our universe can generate, and so it’s the furthest thing, it’s the biggest thing. And I think a lot about the nature of life across different scales. And so we have cells inside of us that are alive and we feel like we’re alive, but we don’t often think about the societies that we’re embedded in as alive or a global- scale organization of us in our technology on the planet as alive. But I think if you have this deeper view into the nature of life, which I think is necessary also to solve the origin of life, then you have to include those things.

The planetary and the bacteria level.
The planetary and the bacteria level.
Sara Walker
Yeah. This is the hard thing about solving the problem of life, I think, is how many things you have to integrate into building a sort of unified picture of this thing that we want to call life. And a lot of our theories of physics are built on building deep regularities that explain a really broad class of phenomena, and I think we haven’t really traditionally thought about life that way. But I think to get at some of these hardest questions like looking for life on other planets or the origin of life, you really have to think about it that way. And so most of my professional work is just trying to understand every single thing on this planet that might be an example of life, which is pretty much everything, and then trying to figure out what’s the deeper structure underlying that.

Sara Walker
Yeah. Schrodinger really tried to do what physicists try to do, which is explain things. And his attempt was to try to explain life in terms of non-equilibrium physics, because he thought that was the best description that we could generate at the time. And so he did come up with something really insightful, which was to predict the structure of DNA as an aperiodic crystal. And that was for a very precise reason, that was the only kind of physical structure that could encode enough information to actually specify a cell. We knew some things about genes, but not about DNA and its actual structure when he proposed that. But in the book, he tried to explain life is kind of going against entropy. And so some people have talked about it as like Schrodinger’s paradox, how can life persist when the second law of thermodynamics is there? But in open systems, that’s not so problematic.

And really the question is, why can life generate so much order? And we don’t have a physics to describe that. And it’s interesting, generations of physicists have thought about this problem. Oftentimes, it’s like when people are retiring, they’re like, “Oh, now I can work on life.” Or they’re more senior in their career and they’ve worked on other more traditional problems. And there’s still a lot of impetus in the physics community to think that non-equilibrium physics will explain life. But I think that’s not the right approach. I don’t think ultimately the solution to what life is there, and I don’t really think entropy has much to do with it unless it’s entirely reformulated.
Lex Fridman
Well, because you have to explain how interesting order, how complexity emerges from the soup.

Theory of everything
Sara Walker
No. Physics hardly even acknowledges that the universe is random at its base. We like to think we live in a deterministic universe and everything’s deterministic. But I think that’s probably an artifact of the way that we’ve written down laws of physics since Newton invented modern physics and his conception of motion and gravity, which he formulated laws that had initial conditions and fixed dynamical laws. And that’s been sort of become the standard canon of how people think the universe works and how we need to describe any physical system is with an initial condition in a law of motion. And I think that’s not actually the way the universe really works. I think it’s a good approximation for the kind of systems that physicists have studied so far.

And I think it will radically fail in the longterm at describing reality at its more basal levels. But I’m not saying there’s a base, I don’t think that reality has a ground, and I don’t think there’s a theory of everything, but I think there are better theories, and I think there are more explanatory theories, and I think we can get to something that explains much more than the current laws of physics do.
Lex Fridman
When you say theory of everything, you mean everything, everything?
When you say theory of everything, you mean everything, everything?
Sara Walker
Yeah. In physics right now, it’s really popular to talk about theories of everything. So string theory is supposed to be a theory of everything because it unifies quantum mechanics and gravity. And people have their different pet theories of everything. And the challenge with the theory of everything, I really love this quote from David Krakauer, which is, “A theory of everything is a theory of everything except those things that theorize.”

Yeah. But it’s also weird because if a theory of everything explained everything, it should also explain the theory. So the theory has to be recursive and none of our theories of physics are recursive. So it’s a weird concept.

But doesn’t it become recursive in that way? And you saying it’s possible to make a theory that’s okay with that?
Sara Walker
I think so. I mean, I don’t think… There’s always going to be the paradox of another meta level you could build on the meta level. So if you assume this is your universe and you’re observe outside of it, you have some meta description of that universe, but then you need a meta description of you describing that universe. So this is one of the biggest challenges that we face being observers inside our universe. And also, why the paradoxes and the foundations of mathematics and any place that we try to have observers in the system or a system describing itself show up. But I think it is possible to build a physics that builds in those things intrinsically without having them be paradoxical or have holes in the descriptions. And so one place I think about this quite a lot, which I think can give you sort of a more concrete example, is the nature of what we call fundamental.

And so one place I think about this quite a lot, which I think can give you sort of a more concrete example, is the nature of what we call fundamental.
So we typically define fundamental right now in terms of the smallest indivisible units of matter. So again, you have to have a definition of what you think material is and matter is, but right now what’s fundamental are elementary particles. And we think they’re fundamental because we can’t break them apart further. And obviously, we have theories like string theory that if they’re right would replace the current description of what’s the most fundamental thing in our universe by replacing with something smaller. But we can’t get to those theories because we’re technologically limited. And so if you look at this from a historical perspective and you think about explanations changing as physical systems like us learn more about the reality in which they live, we once considered atoms to be the most fundamental thing. And it literally comes from the word indivisible. And then we realized atoms had substructure because we built better technology, which allowed us to “See the world better” and resolve smaller features of it.
And then we built even better technology, which allowed us to see even smaller structure and get down to the standard model particles. And we think that there might be structure below that, but we can’t get there yet with our technology. So what’s fundamental, the way we talk about it in current physics is not actually fundamental, it’s the boundaries of what we can observe in our universe, what we can see with our technology. And so if you want to build a theory that’s about us and about what’s inside the universe that we can observe, not what’s at the boundary of it, you need to talk about objects that are in the universe that you can actually break apart to smaller things. So I think the things that are fundamental are actually the constructed objects.
They’re the ones that really exist, and you really understand their properties because you know how the universe constructed them because you can actually take them apart. You can understand the intrinsic laws that built them. But the things that the boundary are just at the boundary, they’re evolving with us, and we’ll learn more about that structure as we go along. But really, if we want to talk about what’s fundamental inside our universe, we have to talk about all these things that are traditionally considered emergent, but really just structures in time that have causal histories that constructed them and are really actually what our universe is about.
Lex Fridman
So we should focus on the construction methodology as the fundamental thing. Do you think there’s a bottom to the smallest possible thing that makes up the universe?

I think so, yeah. I think for me, the frontier in modern physics, where the new physics lies is not in high energy particle physics, it’s not in quantum gravity, it’s not in any of these sort of traditionally sold, “This is going to be the newest deepest insight we have into the nature of reality.” It is going to be in studying the problems of life and intelligence and the things that are sort of also our current existential crises as a civilization or a culture that’s going through an existential trauma of inventing technologies that we don’t understand right now.

I think it seems to me when I see a lot of the ways other people react to new ideas that they don’t feel that way intrinsically. But for me, that’s why I do what I do. I love that feeling.

Yeah. I’m trying to embody that. Because I think you have to live the physics to understand it. But there’s a great quote about Einstein. I don’t know if this is true or not, that he once said that he could feel like beam in his belly. But I think you got to think about it though, right?

Origin of life
Lex Fridman
So what do you think is the origin of life on earth and how can we talk about it in a productive way?
So what do you think is the origin of life on earth and how can we talk about it in a productive way?
Sara Walker
The origin of life is like this boundary that the universe can only cross if a structure that emerges can reinforce its own existence, which is self-reproduction, autocatalysis, things people traditionally talk about. But it has to be able to maintain its own existence against this sort of randomness that happens in chemistry, and this randomness that happens in the quantum world. And it’s in some sense the emergence of a deterministic structure that says, “I’m going to exist and I’m going to keep going.” But pinning that down is really hard. We have ways of thinking about it in assembly theory that I think are pretty rigorous. And one of the things I’m really excited about is trying to actually quantify in an assembly theoretic way when the origin of life happens. But the basic process I have in mind is a system that has no causal contingency, no constraints of objects, basically constraining the existence of other objects or forming or allowing the existence of other objects.

But the basic process I have in mind is a system that has no causal contingency, no constraints of objects, basically constraining the existence of other objects or forming or allowing the existence of other objects.
And so that sounds very abstract, but you can just think of a chemical reaction can’t happen if there’s not a catalyst, for example. Or a baby can’t be born if there wasn’t a parent. So there’s a lot of causal contingency that’s necessary for certain things to happen. So you think about this sort of unconstrained random system, there’s nothing that reinforces the existence of other things. So those sort of resources just get washed out in all of these different structures and none of them exist again, or they’re not very complicated if they’re in high abundance.
And some random events allow some things to start reinforcing the existence of a small subset of objects. And if they can do that, just molecules basically recognizing each other and being able to catalyze certain reactions. There’s this kind of transition point that happens where, unless you get a self-reinforcing structure, something that can maintain its own existence, it actually can’t cross this boundary to make any objects in high abundance without having this sort of past history that it’s carrying with us and maintaining the existence of that past history. And that boundary point where objects can’t exist unless they have the selection and history in them, is what we call the origin of life.
And pretty much everything beyond that boundary is holding on for dear life to all of the causation and causal structure that’s basically put it there, and it’s carving its way through this possibility space into generating more and more structure. And that’s when you get the open-ended cascade of evolution. But that boundary point is really hard to cross. And then what happens when you cross that boundary point and the way objects come into existence is also really fascinating dynamics, because as things become more complex, the assembly index increases. I can explain all these things. Sorry. You can tell me what you want to explain or what people will want to hear. This… Sorry, I have a very vivid visual in my brain and it’s really hard to articulate it.

I really like the self-reinforcement of the objects. Just so I understand, one way to create a lot of the same kind of object is make the self-reinforcing?

Sara Walker
Yes. So self-reproduction has this property. If the system can make itself, then it can persist in time because all objects decay, they all have a finite lifetime. So if you’re able to make a copy of your self before you die, before the second law eats you or whatever people think happens, then that structure can persist in time.

And so what ends up happening is that you get structures that enable the existence of other things, and then somehow only for some sets of objects, you get closed structures that are self-reinforcing and allow that entire structure to persist.

It’s low probability, but once you solve that, once you close the loop, you can create a lot of those objects?
Sara Walker
And that’s what we’re trying to figure out, is what are the causal constraints that close the loop? So there is this idea that’s been in the literature for a really long time that was originally proposed by Stuart Kauffman as really critical to the origin life called, autocatalytic sets. So autocatalytic set is exactly this property we have A makes B, B makes C, C makes A, and you get a closed system. But the problem with the theory of autocatalytic sets is incredibly brittle as a theory and it requires a lot of ad hoc assumptions. You have to assume function, you have to say this thing makes B. It’s not an emergent property, the association between A and B. And so the way I think about it is much more general. If you think about these histories that make objects, it’s kind of like the structure of the histories becomes, collapses in such a way that these things are all in the same sort of causal structure, and that causal structure actually loops back on itself to be able to generate some of the things that make the higher level structures.

Lee has a beautiful example of this actually in molybdenum. It’s like the first non-organic autocatalytic set. It’s a self-reproducing molybdenum ring. But it’s like molybdenum. And basically if you look at the molybdenum, it makes a huge molybdenum ring. I don’t remember exactly how big it is. It might be like 150 molybdenum atoms or something. But if you think about the configuration space of that object, it’s exponentially large how many possible molecules. So why does the entire system collapse on just making that one structure? If you start from molybdenum atoms that are maybe just a couple of them stuck together. And so what they see in this system is there’s a few intermediate stages. So there’s some random events where the chemistry comes together and makes these structures. And then once you get to this very large one, it becomes a template for the smaller ones. And then the whole system just reinforces its own production.

And there’s some things that he would just… People would just take for granted about chemical structures that he was deeply perplexed about. Just like why are these really intricate, really complex structures forming so easily under these conditions? And he was really interested in life, but he started in that field. So he’s just carried with him these sort of deep insights from these systems that seem like they’re totally not alive and just like these metallic chemistries into actually thinking about the deep principles of life. So I think he already knew a lot about that chemistry. And he also, assembly theory came from him thinking about how these systems work. So he had some intuition about what was going on with this molybdenum ring.

They knew about them for a long time, but they didn’t know that the mechanism of why that particular structure form was all catalytic feedback. And so that’s what they figured out in this paper. And I actually think that paper is revealing some of the mechanism of the origin life transition. Because really what you see the origin of life is basically like you should have a combinatorial explosion of the space of possible structures that are too large to exhaust. And yet you see it collapse on this really small space of possibilities that’s mutually reinforcing itself to keep existing. That is the origin of life.

Many, many starts and it keeps starting maybe.
Sara Walker
Yes. Yeah. I mean, there’s also all kinds of other weird properties that happen around this kind of phase boundary. So this other project that I have in my lab is focused on the origin of chirality, which is thinking about… So chirality is this property molecules that they can come in mirror image forms. So just like chirality means hand. So your left and right hand are what’s called non-superimposable, because if you try to lay one on the other, you can’t actually lay them directly on top of each other. And that’s the property being a mirror image. So there’s this sort of perplexing property of the chemistry of life that no one’s been able to really adequately explain, that all of the amino acids in proteins are left-handed and all of the bases in RNA and DNA are right-handed. And yet the chemistry of these building block units, amino acids and nucleobases is the same for left.

And yet the chemistry of these building block units, amino acids and nucleobases is the same for left.
And so you have to have some kind of symmetry breaking where you go from these chemistries that seem entirely equivalent, to only having one chemistry takeover is the dominant form. And for a long time, I had been really… I actually did my PhD on the origin of chirality. I was working on it as a symmetry breaking problem in physics. This is how I got started in the origin of life. And then I left it for a long time because I thought it was one of the most boring problems in the origin of life, but I’ve come back to it. I think there’s something really deep going on here related to this combinatorial explosion of the space of possibilities. But just to get to that point, this feature of this handedness has been the main focus. But people take for granted the existence of chiral molecules at all, that this property of having a handedness, and they just assume that it’s just a generic feature of chemistry.
But if you actually look at molecules, if you look at chemical space, which is the space of all possible molecules that people can generate, and you look at small molecules, things that have less than about seven to 11 heavy atoms. So things that are not hydrogen, almost every single molecule in that space is achiral, like doesn’t have a chiral center. So it would be like a spoon. A spoon doesn’t have, it’s the same as its mirror image. It’s not like a hand that’s different than its mirror image. But if you get to this threshold boundary, above that boundary, almost every single molecule is chiral.
So you go from a universe where almost nothing has a mirror image form, there’s no mirror image universe of possibilities to this one where every single structure has pretty much a mirror image version. And what we’ve been looking at in my lab is that, it seems to be the case that the origin of life transition happens around the time when you start accumulating, you push your molecules to a large enough complexity that chiral molecules become very likely to form. And then there’s a cascade of molecular recognition where chiral molecules can recognize each other. And then you get this sort of autocatalytic feedback and things self-reinforcing.
Lex Fridman
So is chirality in itself an interesting feature or just an accident of complexity?
So is chirality in itself an interesting feature or just an accident of complexity?
Sara Walker
No, it’s a super interesting feature. I think chirality breaks symmetry in time, not space. So we think of it as a spatial property, like a left and right hand. But if I choose the left hand, I’m basically choosing the future of that system for all time, because I’ve basically made a choice between the ways that that molecule can now react with every other object in its chemical universe.

Oh, I see.
Sara Walker
And so you’re actually, when you have the splitting of making a molecule that now has another form it could have had by the same exact atomic composition, but now it’s just a mirror image isometry, you’re basically splitting the universe of possibilities every time.

Lex Fridman
Yeah. In two.
Yeah. In two.
Sara Walker
In two, but molecules can have more than one chiral center, and that’s not the only symmetry that they can have. So this is one of the reasons that Taxol fills 1.5 universes of space. It’s all of these spatial permutations that you do on these objects that actually makes the space so huge. So the point of this sort of chiral transition that I am pointing out is, chirality is actually signature of being in a complex chemical space. And the fact that we think it’s a really generic feature of chemistry and it’s really prevalent is because most of the chemistry we study on earth is a product already of life.

And it also has to do with this transition in assembly, this transition in possibility spaces, because I think there’s something really fundamental going on at this boundary, that you don’t really need to go that far into chemical space to actually see life in terms of this depth in time, this depth in symmetries of objects, in terms of chiral symmetries or this assembly structure. But getting past this boundary that’s not very deep in that space requires life. It’s a really weird property, and it’s really weird that so many abrupt things happen in chemistry at that same scale.
Lex Fridman
So would that be the greatest invention ever made on earth in its evolutionary history? I really like that formulation of it. Nick Lane has a book called Life Ascending, where he lists the 10 great inventions of evolution, the origin of life being first and DNA, the hereditary material that encodes the genetic instructions for all living organisms. Then photosynthesis, the process that allows organisms to convert sunlight into chemical energy, producing oxygen as a byproduct, the complex cell, eukaryotic cells, which contain in nucleus and organelles arose from simple bacterial cells. Sex, sexual reproduction. Movement, so just the ability to move under which you have the predation, the predators and ability of living organisms.

I like sight as an invention, because I think having sensory perception and trying to comprehend the world, to use anthropocentric terms, is a really critical feature of life. And I also, it’s interesting the way that site has complexified over time. So if you think at the origin of life, nothing on the planet could see. So for a long time, life had no sight, and then photon receptors were invented. And then when multicellular evolved, those cells eventually grew into eyes and we had the multicellular eye.

And then it’s interesting when you get to societies like human societies, that we invent even better technologies of seeing, like telescopes and microscopes, which allow us to see deeper into the universe or at smaller scales. So I think that’s pretty profound, the way that site has transformed the ability of life to literally see the reality in which it’s existing in. I think consciousness is also obviously deeply interesting. I’ve gotten kind of obsessed with octopus. They’re just so weird. And the fact that they evolved complex nervous systems kind of independently seems very alien.

A lot of people study that, and there’s a lot of advances being made now in that field. I think it’s pretty shocking though that how little we know about that process. And often it’s left off of people’s lists, it’s just kind of interesting. Embryogenesis is fascinating.

Can you explain assembly theory to me? I listened to Lee talk about it for many hours, and I understood nothing. No, I’m just kidding. I just wanted to take another… You’ve been already talking about it, but just what from a big picture view is the assembly theory way of thinking about our world, about our universe.

Sara Walker
Yeah. I think the first thing is the observation that life seems to be the only thing in the universe that builds complexity in the way that we see it here. And complexity is obviously a loaded term, so I’ll just use assembly instead because I think assembly is more precise. But the idea that all the things on your desk here from your computer, to the pen, to us sitting here don’t exist anywhere else in the universe as far as we know, they only exist on this planet and it took a long evolutionary history to get to us, is a real feature that we should take seriously as one that’s deeply embedded in the laws of physics and the structure of the universe that we live in.

Standard physics would say that all of that complexity traces back to the infinitesimal deviations and the initial state of the universe that there was some order there. I find that deeply unsatisfactory. And what assembly theory says that’s very different is that, the universe is basically constructing itself, and when you get to these combinatorial spaces like chemistry, where the space of possibilities is too large to exhaust them all, you can only construct things along historically contingent paths, like you basically have causal chains of events that happen to allow other things to come into existence.
And that this is the way that complex objects get formed, is basically on scaffolding on the past history of objects, making more complex objects, making more complex objects. That idea in itself is easy to state and simple, but it has some really radical implications as far as what you think is the nature of the physics that would describe life. And so what assembly theory does formally is try to measure the boundary in the space of all things that chemically could exist. For example, like all possible molecules, where’s the boundary above which we should say these things are too complex to happen outside of an evolutionary chain of events, outside of selection. And we formalize that with two observables. One of them is the copy number, the object. So…

… is that with two observables. One of them is the copy number of the object. How many of the object did you observe? And the second one is what’s the minimal number of recursive steps to make it? If you start from elementary building blocks, like bonds for molecules, and you put them together, and then you take things you’ve made already and build up to the object, what’s the shortest number of steps you had to take?

If you start from elementary building blocks, like bonds for molecules, and you put them together, and then you take things you’ve made already and build up to the object, what’s the shortest number of steps you had to take?
And what Lee’s been able to show in the lab with his team is that for organic chemistry, it’s about 15 steps. And then you only see molecules that the only molecules that we observe that are past that threshold are ones that are in life. And in fact, one of the things I’m trying to do with this idea of trying to actually quantify the origin of life as a transition in… A phase transition and assembly theory is actually be able to explain why that boundary is where because I think that’s actually the boundary that life must cross.
The idea of going back to this thing we were talking about before about these structures that can reinforce their own existence and move past that boundary, 15 seems to be that boundary in chemical space. It’s not a universal number. It will be different for different assembly spaces, but that’s what we’ve experimentally validated so far. And then-
Lex Fridman
Literally 15, the assembly index is 15?
Literally 15, the assembly index is 15?

The copy number is the number of exact copies. That’s what you mean by high abundance and assembly index or the complexity of the object is how many steps it took to create it. Recursive.

Sara Walker
Recursive. Yeah. You can think of objects in assembly theory as basically recursive stacks of the construction steps to build them. They’re like, it’s like you take this step and then you make this object and you make it this object and make this object, and then you get up to the final object. But that object is all of that history rolled up into the current structure.

Sara Walker
It turns out, now if you look at objects… And so we define something we call the assembly universe. And assembly universe is ordered in time. It’s actually ordered in the causation, the number of steps to produce an object. And so, all objects in the universe are in some sense existed, a layer that’s defined by their assembly index.

It’s actually ordered in the causation, the number of steps to produce an object. And so, all objects in the universe are in some sense existed, a layer that’s defined by their assembly index.
And the size of each layer is growing exponentially. What you’re talking about, if you want to look at the long way of getting to an object, as I’m increasing the assembly index of an object, I’m moving deeper and deeper into an exponentially growing space. And it’s actually also the case that the typical path to get to that object is also exponentially growing with respect to the assembly index.
And so, if you want to try to make a more and more complex object and you want to do it by a typical path, that’s actually an exponentially receding horizon. And so most objects that come into existence have to be causally very similar to the things that exist because close by in that space, and they can actually get to it by an almost shortest path for that object.
Lex Fridman
Yeah. The almost shortest path is the most likely and by a lot.

Sara Walker
Yeah. I mean basically, the more complex we live in a space that is growing exponentially large. And the ways of getting to objects in the space are also growing exponentially large. And so, we’re this recursively stacked structure of all of these objects that are clinging onto each other for existence. And then they grab something else and are able to bring that thing into existence similar to them.

Yeah. You tweeted, “The most significant struggle for existence in the evolutionary process is not among the objects that do exist, but between the ones that do and those that never have the chance to. This is where selection does most of its causal work.

There was this website, I forgot what it was, but it’s like a neural network that just generates a human face. And it’s like this person does not exist. I think that’s what it’s called. You can just click on that all day and you can look at people all day that don’t exist. All of those people exist in that space of things that don’t exist.

Sara Walker
Yeah. The struggle of the quote, the struggle for existence is that goes all the way back to Darwin’s writing about natural selection. The whole idea of survival of the fittest is everything struggling to exist, this predator-prey dynamic. And the fittest survive. And so, the struggle for existence is really what selection is all about.

The whole idea of survival of the fittest is everything struggling to exist, this predator-prey dynamic. And the fittest survive. And so, the struggle for existence is really what selection is all about.
And that’s true. We do see things that do exist competing to continue to exist. But if you think about this space of possibilities and each time the universe generates a new structure or an object that exists, generates a new structure along this causal chain. It’s generating something that exists that never existed before.
And each time that we make that kind of decision, we’re excluding a huge piece of possibilities. And so actually, as this process of increasing assembly index, it’s not just that the space that these objects exist in is exponentially growing, but there are objects in that space that are exponentially receding away from us. They’re becoming exponentially less and less likely to ever exist. And so, existence excludes a huge number of things.
Lex Fridman
Just because of the accident of history, how it ended up?
Just because of the accident of history, how it ended up?
Sara Walker
Yeah. It is in part an accident because I think some of the structure that gets generated is driven a bit by randomness. I think a lot of it…. One of the conceptions that we have in assembly theory is the universe is random at its base. You can see this in chemistry, unconstrained chemical reactions are pretty random. And also, quantum mechanics, there’s lots of places that give evidence for that.

And also, quantum mechanics, there’s lots of places that give evidence for that.
And deterministic structures emerge by things that can causally reinforce themselves and maintain persistence over time. And so, we are some of the most deterministic things in the universe. And so, we can generate very regular structure and we can generate new structure along a particular lineage. But the possibility space at the tips, the things we can generate next is really huge.
There’s some stochasticity in what we actually instantiate as the next structures that get built in the biosphere. It’s not completely deterministic because the space of future possibilities is always larger than the space of things that exist now.
Lex Fridman
How many instantiations of life is out there, do you think? How often does this happen? What we see happen here on earth, how often is this process repeated throughout our galaxy, throughout the universe?

Sara Walker
I said before, right now, I think the origin of life is a continuous process on earth. I think this idea of combinatorial spaces that our biosphere generates not just chemistry, but other spaces often cross this threshold where they then allow themselves to persist with particular regular structure over time.

Language is another one where the space of possible configurations of the 26 letters of the English alphabet is astronomically large, but we use with very high regularity, certain structures. And then we associate meaning to them because of the regularity of how much we use them. Meaning is an emergent property of the causation and the objects and how often they recur and what the relationship of the recurrence is to other objects.
Lex Fridman
Meaning is the emergent property. Okay, got it.

Well, this is why you can play with language so much actually. Words don’t really carry meaning, it’s just about how you lace them together.

And I do this all the time, and you have to do it with the kind of work that I do because if you want to discover an abstraction, like some keep concept that we don’t understand yet, it means we don’t have the language. And so, the words that we have are inadequate to describe the things.
This is why we’re having a hard time talking about assembly theory because it’s a newly emerging idea. And so, I’m constantly playing with words in different ways to try to convey the meaning that is actually behind the words, but it’s hard to do.

No, I like playing with words a lot. It’s very funny because I know you talked about this with Lee, but people were so offended by the writing of the paper that came out last fall. And it was interesting because the ways that we use words were not the way that people were interacting with the words. And I think that was part of the mismatch where we were trying to use words in a new way because we were trying to describe something that hadn’t been described adequately before, but we had to use the words that everyone else uses for things that are related. And so, it was really interesting to watch that clash play out in real time for me, being someone that tries to be so precise with my word usage, knowing that it’s always going to be vague.

This goes into the are you on the boundary of insane or not? But when you think about the structure of the physics of what we are, that deeply, it really changes your conception of things. And going to this idea of the universe being small in physical space compared to how big it is in time and how large we are. It really makes me question about whether there’s any other structure that’s this giant crystal in time, this giant causal structure, like our biosphere/technosphere is anywhere else in the universe.

But I think when the universe is expanding, it’s expanding in space, but in assembly theory, it’s also expanding in time. And actually that’s driving the expansion in space. And expansion in time is also driving the expansion in the combinatorial space of things on our planet. That’s driving the pace of technology and all the other things. Time is driving all of these things, which is a little bit crazy to think that the universe is just getting bigger because time is getting bigger.

Time is driving all of these things, which is a little bit crazy to think that the universe is just getting bigger because time is getting bigger.
But the sort of visual that gets built in my brain about that is the structure that we’re building on this planet is packing more and more time in this very small volume of space because our planet hasn’t changed its physical size in 4 billion years, but there’s a ton of causation and recursion and time, whatever word you want to use, information packed into this.
And I think this is also embedded in the virtualization of our technologies or the abstraction of language and all of these things. These things that seem really abstract are just really deep in time. And so, what that looks like is you have a planet that becomes increasingly virtualized. And so it’s getting bigger and bigger in time, but not really expanding out in space. And the rest of space is moving away from it. Again, it’s a exponentially receding horizon. And I’m just not sure how far into this evolutionary process something gets if it can ever see that there’s another such structure out there.
Lex Fridman
What do you mean by virtualized in that context?
What do you mean by virtualized in that context?
Sara Walker
Virtual as a play on virtual reality and simulation theories. But virtual also in a sense of, we talk about virtual particles in particle physics, which they are very critical to doing calculations about predicting the properties of real particles, but we don’t observe them directly.

What I mean by virtual here is virtual reality for me, things that appear virtual, appear abstract are just things that are very deep in time in the structure of the things that we are. If you think about you as a 4 billion year old object, the things that are a part of you, like your capacity to use language or think abstractly or have mathematics are just very deep temporal structures. That’s why they look like they’re informational and abstract is because they’re existing in this temporal part of you, but not necessarily spatial part.
Lex Fridman
Just because I have a 4 billion year old history, why does that mean I can’t hang out with aliens?
Just because I have a 4 billion year old history, why does that mean I can’t hang out with aliens?
Sara Walker
There’s a couple ideas that are embedded here. One of them comes again from Paul. He wrote this book years ago about the eerie silence and why we’re alone. And he concluded the book with this idea of quinteligence or something. But this idea that really advanced intelligence would basically just build itself into a quantum computer and it would want to operate in the vacuum of space, because that’s the best place to do quantum computation. And it would just run out all of its computations indefinitely, but it would look completely dark to the rest of the universe.

And it would just run out all of its computations indefinitely, but it would look completely dark to the rest of the universe.
As typical, I don’t think that’s actually the right physics, but I think something about that idea as I do with all ideas is partially correct. And Freeman Dyson also had this amazing paper about how long life could persist in a universe that was exponentially expanding. And his conception was if you imagine analog life form, it could run slower and slower and slower and slower and slower as a function of time. And so, it would be able to run indefinitely, even against an exponentially expanding universe because it would just run exponentially slower.
And so, I guess part of what I’m doing in my brain is putting those two things together along with this idea that, if you imagine with our technology, we’re now building virtual realities, things we actually call virtual reality. Which required four billions years of history and a whole bunch of data to basically embed them in a computer architecture. Now you can put an Oculus headset on and think that you’re in this world.
And what you really are embedded in is in a very deep temporal structure. And so, it’s huge in time, but it’s very small in space. And you can go lots of places in the virtual space, but you’re still stuck in your physical body and sitting in the chair. And so, part of it is it might be the case that sufficiently evolved biospheres virtualize themselves. And they internalize their universe in their temporal causal structure, and they close themselves off from the rest of the universe.
Lex Fridman
I just don’t know if a deep temporal structure necessarily means that you’re closed off.
I just don’t know if a deep temporal structure necessarily means that you’re closed off.
Sara Walker
No, I don’t either. that’s my fear. I’m not sure I’m agreeing with what I say. I’m just saying this is one conclusion. And in my most, it’s interesting, I don’t do psychedelic drugs. But when people describe to me your thing with the faces and stuff, and I’ve had a lot of deep conversations with friends that have done psychedelic drugs for intellectual reasons and otherwise. But I’m always like, “Oh, it sounds like you’re just doing theoretical physics. That’s what brains do on theoretical physics.”

But I’m always like, “Oh, it sounds like you’re just doing theoretical physics. That’s what brains do on theoretical physics.”
I live in these really abstract spaces most of the time. But there’s also this issue of extinction. Extinction events are basically pinching off an entire causal structure. The one of these… I’m going to call them time crystals, I don’t know what, but there’s these very large objects in time. Pinching off that whole structure from the rest of it. And so it’s like, if you imagine that same thing in the universe, I once thought that sufficiently advanced technologies would look like black holes.
Lex Fridman
That would be just completely imperceptible to us.

Yeah. But the other way I think about it is there is probably hopefully life out there. I do work on life detection efforts in the solar system and I’m trying to help with the Habitable Worlds Observatory mission planning right now and working with the biosignatures team for that to think about exoplanet biosignatures. I have some optimism that we might find things, but there are the challenges that we don’t know the likelihood for life, which is what you were talking about.

I have some optimism that we might find things, but there are the challenges that we don’t know the likelihood for life, which is what you were talking about.
If I get to a more grounded discussion, what I’m really interested in doing is trying to solve the origin of life so we can understand how likely life is out there. I think that the problem of discovering alien life and solving the origin of life are deeply coupled and in fact are one in the same problem, and that the first contact with alien life will actually be in an origin of life experiment. But that part I’m super interested in.
And then there’s this other feature that I think about a lot, which is our own technological phase of development as what is this phase in the evolution of life on a planet? If you think about a biosphere emerging on a planet and evolving over billions of years and evolving into a technosphere. When a technosphere can move off planet and basically reproduce itself on another planet, now you have biospheres reproducing themselves. Basically they have to go through technology to do that.
And so, there are ways of thinking about the nature of intelligent life and how it spreads in that capacity that I’m also really excited about and thinking about. And all of those things for me are connected. We have to solve the origin of life in order for us to get off planet because we basically have to start life on another planet. And we also have to solve the origin life in order to recognize other alien intelligence. All of these things are literally the same problem.
Lex Fridman
Right. Understanding the origin of life here on earth is a way to understand ourselves. And to understanding ourselves as a prerequisite from being able to detect other intelligent civilizations. I, for one, take it for what it’s worth on Ayahuasca, one of the things I did is zoom out aggressively, like a spaceship. And it would always go quickly through the galaxy and from the galaxy to this representation of the universe. And at least for me from that perspective, it seemed like it was full of alien life. Not just alien life, but intelligent life.

And conscious life. I don’t know how to convert it into words. It’s more like a feeling. Like you were saying, a feeling converted to a visual to converted to words. I had a visual with it, but really it was a feeling that it was just full of this vibrant energy that I was feeling when I’m looking at the people in my life and full of gratitude. But that same exact thing is everywhere in the universe.

Right. I totally agree with this, that visual I really love. And I think we live in a universe that generates life and purpose, and it’s part of the structure of just the world. And so maybe this lonely view I have is, I never thought about it this way until you’re describing that. I was like, I want to live in that universe. And I’m a very optimistic person and I love building visions of reality that are positive. But I think for me right now in the intellectual process, I have to tunnel through this particular way of thinking about the loneliness of being separated in time from everything else. Which I think we also all are, because time is what defines us as individuals.

But also part of what I mean is you have to go through ideas you don’t necessarily agree with to work out what you’re trying to understand. And I’m trying to be inside this structure so I can really understand it. And I don’t think I’ve been able to… I am so deeply embedded in what we are intellectually right now that I don’t have an ability to see these other ones that you’re describing, if they’re there.

Great Perceptual Filter
Lex Fridman
Well, one of the things you described that you already spoke to, you call it the great perceptual filter. There’s the famous great filter, which is basically the idea that there’s some really powerful moment in every intelligent civilization where they destroy themselves. That explains why we have not seen aliens. And you’re saying that there’s something like that in the temporal history of the creation of complex objects, that at a certain point they become an island, an island too far to reach based on the perceptions?

I mean, it was awesome to me. It was exactly that. It was like lights. The way you maybe see a city, but a city from up above. You see a city with the flickering lights, but there’s a coldness to the city. You know that humans are capable of good and evil. And you could see there’s a complex feeling to the city. I had no such complex feeling about seeing the lights of all the galaxies, whatever, the billions of galaxies.

Yeah, this is cool. I’ll answer the question in a second, but just maybe this idea of flickering lights and intelligence is interesting to me because we have such a human-centric view of alien intelligences that a lot of the work that I’ve been doing with my lab is just trying to take inspiration from non-human life on earth.

And so, I have this really talented undergrad student that’s basically building a model of alien communication based on fireflies. One of my colleagues, Orit Peleg, is she’s totally brilliant. But she goes out with GoPro cameras and films in high resolution, all these firefly flickering. And she has this theory about how their signaling evolved to maximally differentiate the flickering pattern. She has a theory basically that predicts this species should flash like this. If this one’s flashing like this, other one’s going to do it at a slower rate so that they can distinguish each other living in the same environment.
And so this undergrad’s building this model where you have a pulsar background of all these giant flashing sources in the universe. And an alien intelligence wants to signal it’s there so it’s flashing a firefly. And I like the idea of thinking about non-human aliens so that was really fun.
Lex Fridman
The mechanism of the flashing unfortunately, is the diversity of that is very high, and we might not be able to see it. That’s what-
The mechanism of the flashing unfortunately, is the diversity of that is very high, and we might not be able to see it. That’s what-
Sara Walker
Yeah. Well, I think there’s some ways we might be able to differentiate that signal. I’m still thinking about this part of it. One is if you have pulsars and they all have a certain spectrum to their pulsing patterns. And you have this one signal that’s in there that’s basically tried to maximally differentiate itself from all the other sources in the universe, it might stick out in the distribution. There might be ways of actually being able to tell if it’s an anomalous pulsar, basically. But I don’t know if that would really work or not. Still thinking about it.

Fashion

You tweeted, “If one wants to understand how truly combinatorially and compositionally complex our universe is, they only need step into the world of fashion. It’s bonkers how big the constructable space of human aesthetics is.” Can you explain, can we explore the space of human aesthetics?

And Stewart Brand has this great infographic about the layers of human society. And I think it starts with the natural sciences and physics at the bottom, and it goes through all these layers and it’s economics. And then fashion is at the top, is the fastest moving part of human culture. And I think I really like that because it’s so dynamic and so short and it’s temporal longevity. Contrasted with studying the laws of physics, which are the deep structure reality that I feel like bridging those scales tells me much more about the structure of the world that I live in.
Lex Fridman
That said, there’s certain kinds of fashions. A dude in a black suit with a black tie seems to be less dynamic. It seems to persist through time.

When the nature paper in the fall when everyone was saying it was controversial and how terrible that… But controversial is good. But when Alexander McQueen first came out with his fashion lines, he was mixing horror and beauty and people were horrified. It was so controversial. It was macabre. He had, it looked like there were blood on the models.

It’s the same way that I play with fashion or the same way that I play with ideas in theoretical physics, there’s always this space that you can just push things just enough so they look like something someone thinks is familiar, but they’re not familiar.

Oh, evolutionarily? Maybe. But then beauty becomes a signal of other things. It’s really not… Then beauty becomes an adaptive trait, so it can change with different, maybe some species would think, well, you thought the frog having babies come out of its back was beautiful and I thought it was grotesque. There’s not a universal definition of what’s beautiful. It is something that is dependent on your history and how you interact with the world. I guess what I like about beauty, like any other concept is when you turn it on its head. Maybe the traditional conception of why women wear makeup and they dress certain ways is because they want to look beautiful and pleasing to people.

I just like to do it because a confidence thing, it’s about embodying the person that I want to be and about owning that person. Then the way that people interact with that person is very different than if I wasn’t using that attribute as part of… Obviously, that’s influenced by the society I live and what’s aesthetically pleasing things. But it’s interesting to be able to turn that around and not have it necessarily be about the aesthetics, but about the power dynamics that the aesthetics create.
Lex Fridman
But you’re saying there’s some function to beauty in that way, in the way you’re describing and the dynamic it creates in the social interaction.

Sara Walker
Well, the point is you’re saying it’s an adaptive trait for sexual selection or something. I’m saying that the adaptation that beauty confers is far richer than that. Some of the adaptation is about social hierarchy and social mobility and just playing social dynamics. Why do some people dress goth? It’s because they identify with a community and a culture associated with that and get, and that’s a beautiful aesthetic. It’s a different aesthetic. Some people don’t like it.

Language
Lex Fridman
Let’s jump from beauty to language. There’s so many ways to explore the topic of language. You called it, you said that language, parts of language or language in itself or the mechanism of language is a kind of living life form. You’ve tweeted a lot about this in all kinds of poetic ways. Let’s talk about the computation aspect of it. You tweeted, ” The world is not a computation, but computation is our best current language for understanding the world. It is important we recognize this so we can start to see the structure of our future languages that will allow us to see deeper than the computation allows us.” What’s the use of language in helping us understand and make sense of the world?

I think one thing that I feel like I notice much more viscerally than I feel like I hear other people describe is that the representations in our mind and the way that we use language are not the things… Actually, this is an important point going back to what Godel did, but also this idea of signs and symbols and all kinds of ways of separating them. There’s the word and then there’s what the word means about the world. We often confuse those things. What I feel very viscerally, I almost sometimes think I have some synesthesia for language or something, and I just don’t interact with it the way that other people do. But for me, words are objects and the objects are not the things that they describe.

They have a different ontology to them. They’re physical things and they carry causation and they can create meaning, but they’re not what we think they are. Also, the internal representations in our mind, the things I’m seeing about this room are probably… They’re small projection of the things that are actually in this room. I think we have such a difficult time moving past the way that we build representations in the mind and the way that we structure our language to realize that those are approximations to what’s out there and they’re fluid, and we can play around with them and we can see deeper structure underneath them that I think we’re missing a lot.
Lex Fridman
But also the life of the mind is, in some ways, richer than the physical reality. Sure. What’s going on in your mind might be a projection.

Sara Walker
Yeah, for sure. I love this essay by Poincare about mathematical creativity where he talks about this sort of frothing of all these things and then somehow you build theorems on top of it and they become concrete. I also think about this with language. It’s like there’s a lot of stuff happening in your mind, but you have to compress it in this few sets of words to try to convey it to someone. It’s a compactification of the space and it’s not a very efficient one. I think just recognizing that there’s a lot that’s happening behind language is really important. I think this is one of the great things about the existential trauma of large language models, I think is the recognition that language is not the only thing required. There’s something underneath it, not by everybody.

Yeah. A lot of my, what happens in my mind when I’m thinking about ideas is I’ve been presented with this information about how people think about things, and I try to go around to different communities and hear the ways that different, whether it’s hanging out with a bunch of artists, or philosophers, or scientists thinking about things. They all think about it different ways. Then I just try to figure out how do you take the structure of the way that we’re talking about it and turn it slightly so you have all the same pieces that everybody sees are there, but the description that you’ve come up with seems totally different. They can understand that they understand the pattern you’re describing, but they never heard the structure underlying it described the way that you describe it.

Yeah, for sure. This is part of the brilliant thing about our collaboration is complimentary skill sets. I love playing with the abstract space of language, and it’s a really interesting playground when I’m working with Lee because he thinks at a much deeper level of abstraction than can be expressed by language. The ideas we work on are hard to talk about for that reason.

I think it’s a very poor language. A lot of people think is a really great one, but I think it has some nice properties. But I think the feature of it that is compelling is this kind of idea of universality, that if you have a language, you can describe things in any other language.

Lex Fridman
Well, for me, one of the people who revealed the expressive power of computation, aside from Alan Turing, is Stephen Wolfram through all the explorations of cellular automata type of objects that he did in a New Kind of Science and afterwards. What do you get from that? The computational worlds that are revealed through even something as simple as cellular automata. It seems like that’s a really nice way to explore languages that are far outside our human languages and do so rigorously and understand how those kinds of complex systems can interact with each other, can emerge, all that kind of stuff.

I don’t think that they’re outside our human languages. I think they define the boundary of the space of human languages. They allow us to explore things within that space, which is also fantastic. But I think there is a set of ideas that takes, and Stephen Wolfram has worked on this quite a lot and contributed very significantly to it. I really like some of the stuff that Stephen’s doing with his physics project, but don’t agree with a lot of the foundations of it. But I think the space is really fun that he’s exploring. There’s this assumption that computation is at the base of reality, and I see it at the top of reality, not at the base, because I think computation was built by our biosphere. It’s something that happened after many billion years of evolution. It doesn’t happen in every physical object.

It’s something that happened after many billion years of evolution. It doesn’t happen in every physical object.
It only happens in some of them. I think one of the reasons that we feel like the universe is computational is because it’s so easy for us as things that have the theory of computation in our minds. Actually, in some sense it might be related to the functioning of our minds and how we build languages to describe the world and sets of relations to describe the world. But it’s easy for us to go out into the world and build computers and then we mistake our ability to do that with assuming that the world is computational. I’ll give you a really simple example. This one came from John Conway. I one time had a conversation with him, which was really delightful. He was really fun. But he was pointing out that if you string lights in a barn, you can program them to have your favorite one dimensional CA and you might even be able to make them do a be capable of universal computation. Is universal computation a feature of the string lights?
Lex Fridman
Well, no.
Well, no.
Sara Walker
No, it’s probably not. It’s a feature of the fact that you as a programmer had a theory that you could embed in the physical architecture of the string lights. Now, what happens though is we get confused by this distinction between us as agents in the world that actually can transfer things that life does onto other physical substrates with what the world is. For example, you’ll see people studying the mathematics of chemical reaction networks and saying, “Well, chemistry is turning universal,” or studying the laws of physics and saying, “The laws of physics are turning universal.” But anytime that you want to do that, you always have to prepare an initial state. You have to constrain the rule space, and then you have to actually be able to demonstrate the properties of computation. All of that requires an agent or a designer to be able to do that.

But it gives you an intuition if you look at a 1D or two cellular automata, it allows you to build an intuition of how you can have complexity emerge from very simple beginnings, very simple initial conditions-
Sara Walker
I think that’s the intuition that people have derived from it. The intuition I get from cellular automata is that the flat space of an initial condition in a fixed dynamical law is not rich enough to describe an open-ended generation process. The way I see cellular automata is they’re embedded slices in a much larger causal structure. If you want to look at a deterministic slice of that causal structure, you might be able to extract a set of consistent rules that you might call a cellular automata, but you could embed them as much larger space that’s not dynamical and is about the causal structure and relations between all of those computations. That would be the space cellular automata live in. I think that’s the space that Stephen is talking about when he talks about his ruliad and these hypergraphs of all these possible computations. But I wouldn’t take that as my base reality because I think again, computation itself, this abstract property computation, is not at the base of reality.

But the thing that was interesting, I think Stephen was trying to make the argument that fundamental particles aren’t fundamental, gravitation is not fundamental. These are just turtles. Computation is fundamental. I remember pointing out to him, I was like, “Well, computation is your turtle. I think it’s a weird turtle to have.”

Without a question to answer, I don’t understand why you’re building a theory of reality.

Well, I started working in the origin of life, and I think what my challenge was there was no one knew what life was. You can’t really talk about the origination of something if you don’t know what it is. The way I would approach it is if you want to understand what life is, then proving that physics is solving the origin of life. There’s the theory of what life is, but there’s the actual demonstration that that theory is an accurate description of the phenomena you aim to describe. Again, they’re the same problem. It’s not like I can decouple origin life from what life is. It’s like that is the problem.

The point, I guess, I’m making about having a question is no matter what slice of reality you take, what regularity of nature you’re going to try to describe, there will be an abstraction that unifies that structure of reality, hopefully. That will have a fundamental layer to it. You have to explain something in terms of something else. If I want to explain life, for example, then my fundamental description of nature has to be something I think that has to do with time being fundamental. But if I wanted to describe, I don’t know the interactions of matter and light, I have elementary particles be fundamental. If I want to describe electricity and magnetism in the 18 hundreds, I have to have waves be fundamental. Right? You are in quantum mechanics. It’s a wave function that’s fundamental because the explanatory paradigm of your theory. I guess I don’t know what problem saying computation is fundamental solves.

Well, I think that the issue is general relativity and quantum mechanics are expressed in mathematical languages, and then computation is a mathematical language. You’re basically saying that maybe there’s a more universal mathematical language for describing theories of physics that we already know. That’s an important question. I do think that’s what Stephen’s trying to do and do well. But then the question becomes, does that formulation of a more universal language for describing the laws of physics that we know now tell us anything new about the nature of reality? Or is it a language?

You also say that’s the easiest of the hard problems is the hard problem of life. What do you think is the nature of intelligence and consciousness? Do you think something like assembly theory can help us understand that?

I think if assembly theory is an accurate depiction of the physics of life, it should shed a lot of light on those problems. In fact, I sometimes wonder if the problems of consciousness and intelligence are at all different than the problem of life, generally. I’m of two minds of it, but I in general try to… The process of my thinking is trying to regularize everything into one theory, so pretty much every interaction I have is like, “Oh, how do I fold that into…” I’m just building this giant abstraction that’s basically trying to take every piece of data I’ve ever gotten in my brain into a theory of what life is. Consciousness and intelligence are obviously some of the most interesting things that life has manifest. I think they’re very telling about some of the deeper features about the nature of life.

It does seem like they’re all flavors of the same thing. But it’s interesting to wonder at which stage does something that we would recognize as life in a canonical silly human way and something that we would recognize as intelligence, at which stage does that emerge? At which assembly index does that emerge? Which assembly index is a consciousness something that you would canonically recognize as consciousness?

We’re not being too philosophical, like “Here’s the thing that moves, and here’s the thing that doesn’t move,” but maybe consciousness precedes that.

Sara Walker
Depending on what you want to explain, as I was saying before, you have to assume something’s fundamental. Because people can’t explain consciousness, there’s a temptation for some people to want to take consciousness as fundamental and assume everything else is derived out of that. Then you get some people that want to assume consciousness preceded life. I don’t find either of those views particularly illuminating because I don’t want to assume a feminology before I explain a thing. What I’ve tried really hard to do is not assume that I think life is anything except hold on to the patterns and structures that seem to be the sort of consistent ways that we talk about this thing. Then try to build a physics that describes that.

I think if you’re thinking about this thinking about living things as these giant causal structures or these objects that are deep in time or whatever language we end up using to describe it seems to me that consciousness is about the fact that we have a conscious experience is because we are these temporally extended objects. Consciousness and the abstraction that we have in our minds is actually a manifestation of all the time that’s rolled up in us. It’s just because we’re so huge that we have this very large inner space that we’re experiencing that’s not, and it’s also separated off from the rest of the world because we’re the separate thread in time. Our consciousness is not exactly shared with anything else because nothing else occupies the same part of time that we occupy. But I can understand something about you maybe being conscious because you and I didn’t separate that far in the past in terms of our causal histories. In some sense, we can even share experiences with each other through language because of that overlap in our structure.

Lex Fridman
Yes.
Yes.
Sara Walker
The reason that my conscious experience is not the same as yours is because we’re separated in time. The fact that I have a conscious experience is because I’m an object that’s super deep in time, so I’m huge in time. That means that there’s a lot that I am basically, in some sense, a universe onto myself because my structure is so large relative to the amount of space that I occupy.

I think there’s a horizon, and I don’t know how to articulate this yet, it’s a little bit like the horizon at the origin of life where the space inside a particular structure becomes so large that it has some access to a space that doesn’t feel as physical. It’s almost like this idea of counterfactuals. I think the past history of your horizon is just much larger than can be encompassed in a small configuration of matter. You can pull this stuff into existence. This property is maybe a continuous property, but there’s something really different about human-level physical systems and human-level ability to understand reality.

I really love David Deutsch’s conception of universal explainers, and that’s related to theory of universal computation. I think there’s some transition that happens there. But maybe to describe that a little bit better, what I can also say is what intelligence is in this framework. You have these objects that are large in time. They were selected to exist by constraining the possible space of objects to this particular, all of the matter is funneled into this particular configuration of object over time.
These objects arise through selection, but the more selection that you have embedded in you, the more possible selection you have on your future. Selection and evolution, we usually think about in the past sense where selection happened in the past, but objects that are high density configurations of matter that have a lot of selection in them are also selecting agents in the universe. They actually embody the physics of selection and they can select on possible futures. I guess what I’m saying with respect to consciousness and the experience we have is that something very deep about that structure and the nature of how we exist in that structure that has to do with how we’re navigating that space and how we generate that space and how we continue to persist in that space.
Artificial life
Lex Fridman
Is there shortcuts we can take to artificially engineering, living organisms, artificial life, artificial consciousness, artificial intelligence? Maybe just looking pragmatically at the LLMs we have now, do you think those can exhibit qualities of life, qualities of consciousness, qualities of intelligence in the way we think of intelligence?

Sara Walker
I think they already do, but not in the way I hear popularly discussed. They’re obviously signatures of intelligence and a part of a ecosystem of intelligence system of intelligent systems. But I don’t know that individually I would assign all the properties to them that people have. It’s a little like, so we talked about the history of eyes before and how eyes scaled up into technological forms. Language has also had a really interesting history and got much more interesting I think once we started writing it down and then inventing books and things. But every time that we started storing language in a new way where we were existentially traumatized by it. The idea of written language was traumatic because it seemed like the dead were speaking to us even though they were deceased. Books were traumatic because suddenly there were lots of copies of this information available to everyone and it was going to somehow dilute it.

Books were traumatic because suddenly there were lots of copies of this information available to everyone and it was going to somehow dilute it.
Large language models are interesting because they don’t feel as static. They’re very dynamic. But if you think about language in the way I was describing before, as language is this very large in time structure. Before it had been something that was distributed over human brains as a dynamic structure. Occasionally, we store components of that very large dynamic structure in books or in written language. Now, we can actually store the dynamics of that structure in a physical artifact, which is a large language model. I think about it almost like the evolution of genomes in some sense, where there might’ve been really primitive genes in the first living things and they didn’t store a lot of information or they were really messy.
Then by the time you get to the eukaryotic cell, you have this really dynamic genetic architecture that’s read writable and has all of these different properties. I think large language models are kind of like the genetic system for language in some sense, where it’s allowing an archiving that’s highly dynamic. I think it’s very paradoxical to us because obviously in human history, we haven’t been used to conversing anything that’s not human. But now we can converse basically with a crystallization of human language in a computer that’s a highly dynamic crystal because it’s a crystallization in time of this massive abstract structure that’s evolved over human history and is now put into a small device.
Lex Fridman
I think crystallization implies that a limit on its capabilities.

I think there’s not, I mean it very purposefully because a particular instantiation of a language model trained on a particular data set becomes a crystal of the language at that time it was trained, but obviously we’re iterating with the technology and evolving it.

Lex Fridman
Yeah. How much smarter is the collective intelligence of humans versus a single human? That’s the question of AGI versus human level intelligence, superhuman level intelligence versus human level intelligence. How much smarter can this thing, when done well, when we solve a lot of the computation complexities, maybe there’s some data complexities and how to really archive this thing, crystallize this thing really well, how powerful is this thing going to be? What’s your thought?

Sara Walker
Actually, I don’t like the language we use around that, and I think the language really matters. I don’t know how to talk about how much smarter one human is than another. Usually, we talk about abilities or particular talents someone has, and going back to David Deutsch’s idea of universal explainers, adopting the view that where the first kinds of structures are biosphere has built that can understand the rest of reality. We have this universal comprehension capability. He makes an argument that basically we’re the first things that actually are capable of understanding anything. It doesn’t mean…

… Things that actually are capable of understanding anything. It doesn’t mean an individual understands everything, but we have that capability. And so there’s not a difference between that and what people talk about with AGI. In some sense, AGI is a universal explainer, but it might be that a computer is much more efficient at doing, I don’t know, prime factorization or something, than a human is. But it doesn’t mean that it’s necessarily smarter or has a broader reach of the kind of things that can understand than a human does.

And so I think we really have to think about is it a level shift or is it we’re enhancing certain kinds of capabilities humans have in the same way that we enhanced eyesight by making telescopes and microscopes? Are we enhancing capabilities we have into technologies and the entire global ecosystem is getting more intelligent? Or is it really that we’re building some super machine in a box that’s going to be smart and kill everybody? It’s not even a science fiction narrative. It’s a bad science fiction narrative. I just don’t think it’s actually accurate to any of the technologies we’re building or the way that we should be describing them. It’s not even how we should be describing ourselves.
Lex Fridman

Sara Walker
Well, these are human questions. Right? I don’t think they’re necessarily questions that we’re going to outsource to an artificial intelligence. I think what is happening and will continue to happen is there’s a co-evolution between humans and technology that’s happening, and we’re coexisting in this ecosystem right now and we’re maintaining a lot of the balance. And for the balance to shift to the technology would require some very bad human actors, which is a real risk, or some sort of… I don’t know, some sort of dynamic that favors… I just don’t know how that plays out without human agency actually trying to put it in that direction.

The rapid rate is scary. So I think the things that are terrifying are the ideas of deepfakes or all the kinds of issues that become legal issues about artificial intelligence technologies, and using them to control weapons or using them for child pornography or faking out that someone’s loved one was kidnapped or killed. There’s all kinds of things that are super scary in this landscape and all kinds of new legislation needs to be built and all kinds of guardrails on the technology to make sure that people don’t abuse it need to be built and that needs to happen. And I think one function of the artificial intelligence doomsday part of our culture right now is it’s our immune response to knowing that’s coming and we’re over scaring ourselves. So we try to act more quickly, which is good, but it’s about the words that we use versus the actual things happening behind the words.

I think one thing that’s good is when people are talking about things in different ways, it makes us think about them. And also, when things are existentially threatening, we want to pay attention to those. But the ways that they’re existentially threatening and the ways that we’re experiencing existential trauma, I don’t think that we’re really going to understand for another century or two, if ever. And I certainly think they’re not the way that we’re describing them now.

Well, I think people are going to have romantic relationships with them, and I also think that some people would be convinced already that they’re conscious, but I think in order… What does it take to convince people that something is conscious? I think that we actually have to have an idea of what we’re talking about. We have to have a theory that explains when things are conscious or not, that’s testable. Right? And we don’t have one right now. So I think until we have that, it’s always going to be this gray area where some people think it hasn’t, some people think it doesn’t because we don’t actually know what we’re talking about that we think it has.

But I don’t like thinking our technologies as a separate species because this again goes back to this sort of levels of selection issue. And if you think about humans individually alive, you miss the fact that societies are also alive. And so I think about it much more in the sense of an ecosystem’s not the right word, but we don’t have the right words for these things of… And this is why I talk about the technosphere. It’s a system that is both human and technological. It’s not human or technological. And so this is the part that I think we are really good, and this is driving in part a lot of the attitude of, “I’ll kill you first with my nuclear weapons.” We’re really good at identifying things as other. We’re not really good at understanding when we’re the same or when we’re part of an integrated system that’s actually functioning together in some kind of cohesive way.

We’re not really good at understanding when we’re the same or when we’re part of an integrated system that’s actually functioning together in some kind of cohesive way.
So even if you look at the division in American politics or something, for example. It’s important that there’s multiple sides that are arguing with each other because that’s actually how you resolve society’s issues. It’s not like a bad feature. I think some of the extreme positions and the way people talk about are maybe not ideal, but that’s how societies solve problems. What it looks like for an individual is really different than the societal level outcomes and the fact that there is… I don’t want to call it cognition or computation. I don’t know what you call it, but there is a process playing out in the dynamics of societies that we are all individual actors in, and we’re not part of that. It requires all of us acting individually, but this higher level structure is playing out some things and things are getting solved for it to be able to maintain itself. And that’s the level that our technologies live at. They don’t live at our level. They live at the societal level, and they’re deeply integrated with the social organism, if you want to call it that.
And so I really get upset when people talk about the species of artificial intelligence. I’m like, you mean we live in an ecosystem of all these intelligent things and these animating technologies that were in some sense helping to come alive. We are generating them, but it’s not like the biosphere eliminated all of its past history when it invented a new species. All of these things get scaffolded, and we’re also augmenting ourselves at the same time that we’re building technologies. I don’t think we can anticipate what that system’s going to look like.

It’s like when the first cell split into two. That’s what I was talking about. When a planet reproduces itself, the technosphere emerges enough understanding. It’s like this recursive, the entire history of life is just recursion. Right? So you have an original life event. It evolves for 4,000,000,000 years, at least on our planet. It evolves the technosphere. The technologies themselves start to become having this property we call life, which is the phase we’re undergoing now. It solves the origin of itself, and then it figures out how that process all works, understands how to make more life and then can copy itself onto another planet so the whole structure can reproduce itself.

And so the origin of life is happening again right now on this planet in the technosphere with the way that our planet is undergoing another transition. Just like at the origin of life, when geochemistry transitioned to biology, which is the global… For me, it was a planetary scale transition. It was a multiscale thing that happened from the scale of chemistry all the way to planetary cycles. It’s happening now, all the way from individual humans to the internet, which is a global technology and all the other things. There’s this multiscale process that’s happening and transitioning us globally, and it’s a dramatic transition. It’s happening really fast and we’re living in it.

I think it does require life to use new energy sources in order to expand the way it is, so that part’s accurate. But I think this process of life being the mechanism that the universe creatively expresses itself, generates novelty, explores the space of the possible is really the thing that’s most deeply intrinsic to life. And so these energy-consuming scales of technology, I think is missing the actual feature that’s most prominent about any alien life that we might find, which is that it’s literally our universe, our reality, trying to creatively express itself and trying to find out what can exist and trying to make it exist.

We have a finite amount of material, whatever way you want to define material. For me, material is time, material is information, but we have a finite amount of material. If time is a generating mechanism, it’s always going to be finite because the universe is… It’s a resource that’s getting generated, but it has a size, which means that all the things that could exist don’t exist. And in fact, most of them never will.

So death is a way to make room in the universe for other things to exist that wouldn’t be able to exist otherwise. So if the universe over its entire temporal history wants to maximize the number of things… Wants is a hard word, maximize is a hard word, all these things are approximate, but wants to maximize the number of things that can exist, the best way to do it is to make recursively embedded stacked objects like us that have a lot of structure and a small volume of space. And to have those things turn over rapidly so you can create as many of them as possible.
Lex Fridman
So that for sure is a bunch of those kinds of things throughout the universe.

If you had to bet money on it, what percent? So say 1,000,000 from now, the story of science and human understanding that started on earth is written, what chapter are we on? Is this 1%, 10%, 20%, 50%, 90%? How much do we understand, like the big stuff, not the details of… Big important questions and ideas?

Lex Fridman
You can’t do that.
You can’t do that.
Sara Walker
I can. You know why I use that though? I’ll tell you why, why my brain went there, is because anybody that gets an education in physics has this trope about how all the great physicists did their best work in their 20s, and then you don’t do any good work after that. And I always thought it was funny because for me, physics is not complete, it’s not nearly complete, but most physicists think that we understand most of the structure of reality. And so I think I put this in the book somewhere, but this idea to me that societies would discover everything while they’re young is very consistent with the way we talk about physics right now. But I don’t think that’s actually the way that things are going to go, and you’re finding that people that are making major discoveries are getting older in some sense than they were, and our lifespan is also increasing.

So I think there is something about age and your ability to learn and how much of the world you can see that’s really important over a human lifespan, but also over the lifespan of societies. And so I don’t know how big the frontier is. I don’t actually think it has a limit. I don’t believe in infinity as a physical thing, but I think as a receding horizon, I think because the universe is getting bigger, you can never know all of it.

Right. Or the theory of gravitation, for example. When we invented that theory, we only knew about the planets in our solar system. And now, many centuries later, we know about all these planets around other stars and black holes and other things that we could never have anticipated. And then we can ask questions about them. We wouldn’t have been asking about singularities and can they really be physical things in the universe several 100 years ago? That question couldn’t exist.

Sara Walker
Yeah. But yeah, that’s consistent with many worlds, right? Because there’s this constant branching, but it doesn’t really have a directionality to it. I don’t know. Many worlds is weird. So my interpretation of reality is if you fold it up, all that bifurcation of many worlds, and you just fold it into the structure that is you, and you just said you are all of those many worlds and your history converged on you, but you’re actually an object exists that was selected to exist, and you’re self-consistent with the other structures. So the quantum mechanical reality is not the one that you live in. It’s this very deterministic, classical world, and you’re carving a path through that space. But I don’t think that you’re constantly branching into new spaces. I think you are that space.

Wait, so to you, at the bottom, it’s deterministic? I thought you said the universe is just a bunch of random-
Wait, so to you, at the bottom, it’s deterministic? I thought you said the universe is just a bunch of random-
Sara Walker
No, it’s random at the bottom. Right? But this randomness that we see at the bottom of reality that is quantum mechanics, I think people have assumed that that is reality. And what I’m saying is all those things you see in many worlds, all those versions of you, just collect them up and bundle them up and they’re all you. And what has happened is elementary particles, they don’t live in a deterministic universe, the things that we study in quantum experiments. They live in this fuzzy random space, but as that structure collapsed and started to build structures that were deterministic and evolved into you, you are a very deterministic macroscopic object. And you can look down on that universe that doesn’t have time in it, that random structure. And you can see that all of these possibilities look possible, but they’re not possible for you because you’re constrained by this giant causal structural history. So you can’t live in all those universes. You’d have to go all the way back to the very beginning of the universe and retrace everything again to be a different you.

So where’s the source of the free will for the macro object?
So where’s the source of the free will for the macro object?
Sara Walker
It’s the fact that you’re a deterministic structure living in a random background. And also, all of that selection bundled in you allows you to select on possible futures. So that’s where your will comes from. And there’s just always a little bit of randomness because the universe is getting bigger. And this idea that the past and the present is not large enough yet to contain the future, the extra structure has to come from somewhere. And some of that is because outside of those giant causal structures that are things like us, it’s fucking random out there, and it’s scary, and we’re all hanging onto each other because the only way to hang on to each other, the only way to exist is to clinging on to all of these causal structures that we happen to coinhabitate existence with and try to keep reinforcing each other’s existence.

I don’t know what I think about that. That’s complicated to imagine. Just that little bit of randomness is enough. Okay.
Sara Walker
Well, it’s not just the randomness. There’s two features. One is the randomness helps generate some novelty and some flexibility, but it’s also that because you’re the structure that’s deep in time, you have this commonatorial history that’s you. And I think about time and assembly theory, not as linear time, but as commonatorial time. So if you have all of the structure that you’re built out of, in principle, your future can be combinations of that structure. You obviously need to persist yourself as a coherent you. So you want to optimize for a future in that combinatorial space that still includes you, most of the time for most of us.

So you want to optimize for a future in that combinatorial space that still includes you, most of the time for most of us.
And then that gives you a space to operate in, and that’s your horizon where your free will can operate, and your free will can’t be instantaneous. So for example, I’m sitting here talking to you right now. I can’t be in the UK and I can’t be in Arizona, but I could plan, I could execute my free will over time because free will is a temporal feature of life, to be there tomorrow or the next day if I wanted to.
Lex Fridman
But what about the instantaneous decisions you’re making like, I don’t know, to put your hand on the table?
But what about the instantaneous decisions you’re making like, I don’t know, to put your hand on the table?

I think those were already decided a while ago. I don’t think free will is ever instantaneous.

What’s outside the universe?
What’s outside the universe?
Sara Walker
Oh, there’s nothing outside the universe. So I am the most physicalist that anyone could be. So for me, everything exists in our universe. And I like to think everything exists here. So even when we talk about the multiverse, to me, it’s not like there’s all these other universes outside of our universe that exist. The multiverse is a concept that exists in human minds here, and it allows us to have some counterfactual reasoning to reason about our own cosmology, and therefore, it’s causal in our biosphere to understanding the reality that we live in and building better theories, but I don’t think that the multiverse is something… And also, math. I don’t think there’s a Platonic world that mathematical things live in. I think mathematical things are here on this planet. I don’t think it makes sense to talk about things that exist outside of the universe. If you’re talking about them, you’re already talking about something that exists inside the universe and is part of the universe and is part of what the universe is building.

Right. And you can say that, and that’s an interesting philosophy. But again, this is pushing on the boundaries of the way that we understand things. I think it’s more constructive to say the fact that I can talk about those things is telling me something about the structure of where I actually live and where I exist.

Yeah. So there’s no such thing as experimental Platonism, but if you think math is an object that emerged in our biosphere, you can start experimenting with that idea. And that to me, is really interesting. Well, mathematicians do think about math sometimes as an experimental science, but to think about math itself as an object for study by physicists rather than a tool physicists use to describe reality, it becomes the part of reality they’re trying to describe, to me, is a deeply interesting inversion.

And then you have to try to convert the feelings into visuals and the visuals into words?
Sara Walker
Yeah. I love the way it makes me feel to have ideas that I think are novel, and I think that the dual side of that is the painful process of trying to communicate that with other human beings to test if they have any kind of reality to them. And I also love that process. I love trying to figure out how to explain really deep abstract things that I don’t think that we understand and trying to understand them with other people. And I also love the shock value of this idea we were talking about before, of being on the boundary of what we understand. And so people can see what you’re seeing, but they haven’t ever saw it that way before.

And so people can see what you’re seeing, but they haven’t ever saw it that way before.
And I love the shock value that people have, that immediate moment of recognizing that there’s something beyond the way that they thought about things before. And being able to deliver that to people, I think is one of the biggest joys that I have, is just… Maybe it’s that sense of mystery to share that there’s something beyond the frontier of how we understand and we might be able to see it.
Lex Fridman
And you get to see the humans transformed, like no idea?
And you get to see the humans transformed, like no idea?
Sara Walker
Yes. And I think my greatest wish in life is to somehow contribute to an idea that transforms the way that we think. I have my problem I want to solve, but the thing that gives me joy about it is really changing something and ideally getting to a deeper understanding of how the world works and what we are.

Yeah, I would say understanding life at a deep level is probably one of the most exciting problems, one of the most exciting questions. So I’m glad you’re trying to answer just that and doing it in style.

Seven years ago, he was cut from House of Cards, and canceled by Hollywood and the world, when Anthony Rapp made an allegation that Kevin Spacey sexually abused him in 1986. Anthony Rapp then filed a civil lawsuit seeking $40 million. In this trial and all civil and criminal trials that followed, Kevin was acquitted. He has never been found guilty nor liable in the court of law.
In this conversation, Kevin makes clear what he did and what he didn’t do. I also encourage you to listen to Kevin’s Dan Wooten and Alison Pearson interviews, for additional details and responses to the allegations.
As an aside, let me say that one of the principles I operate under for this podcast and in life is that I will talk with everyone with empathy and with backbone. For each guest, I hope to explore their life’s work, life’s story, and what and how they think, and do so honestly and fully, the good, the bad, and the ugly, the brilliance and the flaws. I won’t whitewash their sins, but I won’t reduce them to a worse possible caricature of their sins either. The latter is what the mass hysteria of internet mobs too often does, often rushing to a final judgment before the facts are in. I will try to do better than that, to respect due process in service of the truth, and I hope to have the courage to always think independently and to speak honestly from the heart, even when the eyes of the outraged mob are on me.
Again, my goal is to understand human beings at their best and at their worst, and the hope is such understanding leads to more compassion and wisdom in the world. I will make mistakes, and when I do, I will work hard to improve. I love you all.

You played a serial killer in the movie, Se7en. Your performance was one of, if not the greatest, portrayal of a murderer on screen ever. What was your process of becoming him, John Doe, the serial killer.
And I’m in New York, I’m back in my … I have a wonderful apartment on West 12th Street, and my mom has come to visit for Christmas, and it’s December 23rd, and it’s like seven o’clock at night, and my phone rings, and it’s Arnold Kopelson, who’s the producer of Se7en, and he’s very jovial and he’s very friendly, and he says, “How are you doing?” And I said, “Fine,” and he said, “Listen, do you remember that film you came in for, Se7en?” And I said, “Yeah, yeah, absolutely.” He goes, “Well, turns out that we hired an actor and we started shooting, and then yesterday David fired him, and David would like you to get on a plane on Sunday, and come to Los Angeles and start shooting on Tuesday.” And I was like, “Okay. Would it be imposing to say, can I read it again? Because it’s been a while now, and I’d like to.” So they sent a script over. I read the script that night. I thought about it, and I had this feeling, I can’t even quite describe it, but I had this feeling that it would be really good if I didn’t take billing in the film, and the reason I felt that was because I knew that by the time this film would come out, it would be the last one of the three movies that I’d just shot, the fourth one. And if any of those films broke through or did well, if it was going to be Brad Pitt, Morgan Freeman, Gwyneth Paltrow, and Kevin Spacey, and you don’t show up for the first 25, 30, 40 minutes, people are going to figure out who you’re playing.
So I got on a plane on that Sunday and I flew to Los Angeles, and I went into where they were shooting, and I went into the makeup room and David Fincher was there, and we were talking about what should I do? How should I look? And I just had my hair short for Outbreak, because I was playing a military character, and I just looked at the hairdresser and I said, do you have a razor? And Fincher went, “Are you kidding?” And I said, “No.” He goes, “If you shave your head, I’ll shave mine.” So we both shaved our heads, and then I started shooting the next day.
So my long-winded answer to your question is that I didn’t have that much time to think about how to build that character. What I think in the end, Fincher was able to do so brilliantly, with such terror, was to set the audience up to meet this character.
So people who somehow didn’t see the movie, there’s these five murders that happened that are inspired by five of the seven deadly sins, and the ending scene is inspired, represents the last two deadly sins, and there’s this calm subtlety about you in your performance, it’s just terrifying. Maybe in contrast with Brad Pitt’s performance, that’s also really strong, but that in the contrast is the terrifying sense that you get in the audience, that builds up to the twist at the end, or the surprise at the end, with the famous, “What’s in the box?” from Brad Pitt, that is Brad Pitt’s character’s wife, her head.
And I think it also is, it’s an example of what makes tragedy so difficult. Very often, tragedy is people operating without enough information. They don’t have all the facts. Romeo and Juliet, they don’t have all the facts. They don’t know what we know as an audience. And so in the end, whether Brad Pitt’s character ends up shooting John Doe, or turning the gun on himself, which was a discussion … there were a number of alternative endings that were discussed … nothing ends up being tied up in a nice little bow. It is complicated, and shows how nobody wins in the end when you’re not operating with all the information.
I’ll tell you a story. This is a story I just love, because it’s in exactly the same wheelhouse. So Jack Lemmon’s first movie was a film called It Should Happen to You, and it was directed by George Cukor. And Jack tells this story and it was just an incredibly charming story to hear Jack tell. He said, “So I am doing this picture, and let me tell you, this is a terrific part for me. And I’m doing a scene, it’s on my first day. It’s my first day, and it’s a terrific scene.” And he goes, “We do the first take, and George Cukor comes up to me and he says, ‘Jack,’ I said, ‘Yeah.’ He said, ‘Could you do, let’s do another one, but just do a little less in this one.’ And Jack said, ‘A little less? A little less than what I just did?’ He said, ‘Yeah, just a little less.'”
So he goes, “We do another take, and I think, ‘Boy, that was it. Let’s just go home,” and Cukor walked up to him. He said, “Jack, let’s do another one this time just a little bit less,” and Jack said, “Less than what I just did now?” He said, “Yeah, just a little bit less.” He goes, “Oh, okay.” So he did another take and Cukor came up and he said, “Jack, just a little bit less,” and Jack said, “A little less than what I just did?” He said, “Yes.” He goes, “Well, if I do any less, I’m not going to be acting,” and Cukor said, “Exactly, Jack. Exactly.”
But then acting styles changed. We got into a different thing in the late ’50s and ’60s, and a lot of actors are feeling it, which I’m not saying it’s a bad thing, it’s just that if you want to keep an audience engaged, as Fincher does, and I believe successfully does in all of his work, pace, timing, movement, clarity, speed, are admirable to achieve.
So very often … Trevor Nunn is this way, a lot of wonderful directors I’ve worked with, they’re really good at helping you trim and edit.
Do you see wisdom in that distinction? And what does it take to do both the dramatization of a text and the seduction of an audience?
And when you saddle that against what maybe he means as an actor, which is more dramatic, or more text-driven more … look, I’ve always believed that my job, not every actor feels this way, but my job, the way that I’ve looked at it, is that my job is to serve the writing, and that if I serve the writing, I will in a sense serve myself, because I’ll be in the right world, I’ll be in the right context, I’ll be in the right style. I’ll have embraced what a director’s … it’s not my painting, it’s someone else’s painting. I’m a series of colors in someone else’s painting, and the barometer for me has always been, that when people stop me and talk to me about a character I’ve played, and reference their name as if they actually exist, that’s when I feel like I’ve gotten close to doing my job.
And then I think more … recently contemporary, when I think of the work that Philip Seymour Hoffman did, and Heath Ledger, and people that, when I think about what they could be doing, what they could do, what they would’ve done had they stayed with us, I’m so excited when I go into a cinema, or I go into a play, and I completely am taken to some place that I believe exists, and characters that become real.
I remember that there’s been times in the creative process when something was pointed out to me, or something was … I remember I was doing a play, and I was having this really tough time with one of the last scenes in the play, and I just couldn’t figure it out. I was in rehearsal, and although we had a director in that play, I called another, a friend of mine, who was also director, and I had him come over and I said, “Look, this scene, I’m just having the toughest, I cannot seem to crack this scene.”
And so we read it through a couple of times, and then this wonderful director named John Swanbeck, who would eventually direct me in a film called The Big Kahuna, but this is before that. He said to me the most incredible thing, he just said, “All right, what’s the last line you have in this scene before you fall over and fall asleep?” And I said, The last line is, ‘That last drink, the old KO,'” and he went, “Okay, I want you to think about what that line actually means and then work backwards.”
And so he left, and I was left with this, “What? What does that mean? How am I supposed to?” And then a couple of days went by, a couple of days went by, and I thought, “Okay, so I see that. What does that line actually mean? Well, that last drink, the old KO. KO is Knockout, which is a boxing term. It’s the only boxing term the writer uses in the play.”
And then I went back, and I realized my friend was so smart and so incredible to have said, “Ask a question you haven’t thought of asking yet.” I realized that the playwright wrote the last round, the eighth round between these two brothers, and it was a fight, physical as well as emotional. And when I brought that into the rehearsal room to the directors doing that play, he liked that idea. And we staged that scene as if it was the eighth round. The audience wouldn’t have known that, but just what I loved about that was that somebody said to me, “Ask yourself a question you haven’t asked yourself yet. What does that line mean? And then work backwards.”
And then he goes, “Okay, let’s bring a rug in, and let’s bring these chairs much closer, and let’s see what happens if the space between you is,” and so then you try it that way. And then it’s a little harder in Shakespeare to improv, but in any situation where you want to try and see where … where could a scene go? Where would the scene go If I didn’t make that choice? Where would the scene go? If I made this choice? Where would the scene go if I didn’t say that, or I said something else? So that’s how improv can be a valuable process to learn about limits and boundaries, and what’s going on with a character, that somehow you discover in trying something that isn’t on the page.
Then there’s the different thing, which is the trying to make it fresh and trying to make it new, and that is really a reference to theater. I’ll put it to you this way. Anybody loves sports, so you go and you watch on a pitch, you watch on a tennis game, you watch basketball, you watch football. Yeah, the rules are the same, but it’s a different game every time you’re out on that court, or on that field.
It’s no different in theater. Yes, it’s the same lines. Maybe even blocking is similar, but what’s different is attack, intention, how you are growing in a role and watching your fellow actors grow in theirs, and how every night it’s a new audience, and they’re reacting differently, and you literally … where you can go from week one of performances in a play to week 12 is extraordinary.
And the difference between theater and film is that no matter how good someone might think you are in a movie, you’ll never be any better. It’s frozen. Whereas I can be better tomorrow night than I was tonight. I can be better in a week than I was tonight. It is a living, breathing, shifting, changing, growing thing, every single day.
First of all, the camaraderie of everybody, the bond theater creates, especially when you’re traveling. But another interesting thing you mentioned with the chairs of Sam Mendes, trying different stuff, it seemed like everybody was really open to trying stuff, embarrassing themselves, taking risks, all of that. I suppose that’s part of acting in general, but theater especially, just take risks. It’s okay to embarrass the shit out of yourself, including the director.
And I was, of course, fortunate that some of the things I learned and observed about being a part of that family, being included in that family, and being a part of creating that family, I was able to observe from people like Jack Lemmon, who led many companies that I was fortunate to work in and be a part of.
There was a scene I had in Glengarry Glen Ross where the character I play has fucked something up, has just screwed something up. And Pacino is livid. And so we had the scene where Al is walking like this and the camera is moving with him, and he is shooing me a new asshole. And in the middle of the take, Al starts talking about me. “Oh, Kevin, you don’t think we know how you got this job? You don’t think we know whose dick you’ve been sucking on to get this part in this movie?” And I’m now, I’m literally like, I don’t know what the hell is happening, but I am reacting. We got to the end of that take. Al walked up to me and he went, “Oh, that was so good. Oh my God, that was so good. Just so you know the sound, I asked them not to record, so you have no dialogue. So it’s just me. Oh, that was so good. You look like a car wreck.” And I was like, “Yeah.” And it was actually an incredibly generous thing that he gave me so that I would react.
And I got the part. Well, I didn’t quite get the part they were going to bring together the actors that they thought they were going to give the parts to on a Saturday at Al’s office. And they asked me if I would come and do a read through. And I said, “Who’s going to be there?” And they said, “Well, so and so and so and so,” and Jack Lemmon is flying in. And I said, “Don’t tell Mr. Lemmon that I’m doing the read through. Is that possible?” They were like, “Sure.”
So I’ll never forget this. Jack was sitting in a chair and Pacino’s office doing the New York Times crossword puzzle as he did every day. And I walked in the door and he went, “Oh, Jesus Christ, is it possible you could get a job without me? Jesus Christ, I’m so tired of holding up your end of it. Oh my God, Jesus.” So I got the job because of Pacino, and it was really one of the first major roles that I ever had in a film to be working with that group-
So I had to get up and do a monologue in front of Mr. Lemmon when I was 13 years old. And he walked up to me at the end of that and he put his hand on my shoulder and he said, “That was just actually terrific.” He said, “No, everything I’ve been talking about you just did. What’s your name?” I said, “Kevin.” He said, “Well, let me tell you something. When you get finished with high school, as I’m sure you’re going to go on and do theater, you should go to New York and you should study to be an actor, because this is what you’re meant to do with your life.” And he was like an idol.
And 12 years later, I read in the New York Times that he was coming to Broadway to do this production of A Long Day’s Journey Into Night, a year and some months after I read this article and I was like, “I’m going to play Jamie in that production.” And I then with a lot of opposition because the casting director didn’t want to see me. They said that the director, Jonathan Miller wanted movie actors to play the two sons. And ultimately, I found out that Jonathan Miller, the director, was coming to New York to do a series of lectures at Alice Tully Hall. And I went to try to figure out how I could maybe meet him. And I was sitting in that theater listening to this incredible lecture he was doing. And sitting next to me was an elderly woman. I mean elderly, 80 something and she was asleep, but sticking out of her handbag, which was on the floor, was a invitation to a cocktail reception in honor of Dr. Jonathan Miller.
And so I thought, “She’s tired. She’s probably going to go home.” So I took that and walked into this cocktail reception and ultimately went over to Dr. Miller who was incredibly kind and said, “Sit down. I’m always very curious what brings young people to my lectures.” And I said to him, “Eugene O’Neill brought me here.” And he was like, “What? I’ve always wanted to meet him. Where is he?” And I told him that I’ve been trying for seven months to get an audition for A Long Day’s Journey, and that his American cast directors were telling my agents that he wanted big American movie stars. And at that moment, he turned and he saw one of those casting directors who was there that night, because I knew he was going to be in New York starting auditions that week.
And she was staring daggers at me and he just got it. And he said, “Does someone have a pen?” And he took a little paper, started writing. He said, “Listen, Kevin, there are many situations in which casting directors have a lot of say and a lot of power and a lot of leverage. And then there are other situations where they just take director’s messages. And on this one, they’re taking my messages, this is where I’m staying, make sure your people get to me. We start auditions on Thursday.” And on Thursday I had an opportunity to come in and audition for this play that I’d been working on and preparing. And at the end of it, I did four scenes. At the end of it, he said to me that unless someone else came in and blew him against the wall, I had just done as far as he was concerned, I pretty much had the part, but I couldn’t tell my agents that yet because I had to come back and read with Mr. Lemmon.
And so three months later, in August of 1985, I found myself in a room with Jack Lemmon again at 890 Broadway, which is where they rehearse a lot of the Broadway plays. And we did four scenes together, and I was toppling over him. I was pushing him, I was relentless. And I’ll never forget, at the end of that, Lemmon came over to me, he put his hand on my shoulder and he said, “That was, your touch was terrific, I never thought we’d find the rotten kid, but he’s it. Jesus Christ. What the hell was that?” And I ended up spending the next year of my life with that man.
I remember this, and I don’t know if this will answer your question, but I think it’s revealing about what he’s able to do and what he was able to do and how that ultimately influenced what I was able to do. Sam Mendes had never directed a film before American Beauty. So what he did was he took the best elements of theater and applied them to the process. So we rehearsed it like a play in a sound stage where everything was laid out, like it would be in a play and this couch will be here. And he’d sent me a couple of tapes. He’d sent me two cassette tapes, one that he’d like to call pre-Lester before he begins to move in a new direction. And then post-Lester, and they just were different songs. And then he said to me one day, and I think always thought this was brilliant of Sam to use Lemmon knowing what Lemmon meant to me.
He said, “When was the last time you watched The Apartment?” And I said, “I don’t know. I mean, I love that movie so much.” He goes, “I want you to watch it again and then let’s talk.” So I went and I watched the movie again, and we sat down and Sam said, “What Lemmon does in that film is incredible because there is never a moment in the movie where we see him change. He just evolves and he becomes the man he becomes because of the experiences that he has through the course of the film. But there’s this remarkable consistency in who he becomes, and that’s what I need you to do as Lester, I don’t want the audience to ever see him change. I want him to evolve.
And so we did some, I mean, first of all, it was just a great direction. And then second of all, we did some things that people don’t know we did to aid that gradual shift of that man’s character. First of all, I had to be in the best shape from the beginning of the movie. We didn’t shoot in sequence. So I was in this crazy shape. I had this wonderful trainer named Mike Torsha, who just was incredible. But so what we did was, in order to then show this gradual shift was I had three different hair pieces.
I had three different kinds of costumes of different colors and sizes, and I had different makeup. So in the beginning, I was wearing a kind of drab, dull, slightly uninspired hair piece, and my makeup was kind of gray and boring, and I was a little bit, there were times when I was too much like this. And Sam would go, “Kevin, you look like Walter Matthau. Would you please stand up a little bit?” We’re sort of midway through at this point. And then at a certain point, the wig changed and it had little highlights in it, a little more color, a little more, the makeup became a little, the suits got a little tighter. And then finally a third wig that was golden highlights and sunshine and rosy cheeks and tight fit. And these are what we call theatrical tricks. This is how an audience doesn’t even know it’s happening, but it is this gradual.
And I just always felt that that was such a brilliant way because he knew what I felt about Jack. And when you watch The Apartment, it is extraordinary that he doesn’t ever change. He just… So I’m, and in fact, I thanked Jack when I won the Oscar and I did my thank you speech, and I walked off stage, and I remember I had to sit down for a moment because I didn’t want to go to the press room because I wanted to see if Sam was going to win. And so I was waiting and my phone rang and it was Lemmon. He said, “You’re a son of a bitch.” I said, “What?” He goes, “First of all, congratulations and thanks for thanking me, because God knows you couldn’t have done it without me.” He said, “Second of all,” he said, “Do you know how long it took me to win from supporting actor? I won for Mr. Roberts, and it took me like 10, 12 years to win Oscar. You did it in four, you son of a bitch.”
I mean, I used to get stopped and someone would say to me, “When I first saw American Beauty, I was married, and the second time I saw it, I wasn’t.” I was like, “Well, we weren’t trying to increase the divorce rate. It wasn’t our intention.” But it is interesting how so many people have those kinds of crazy fantasies. And what I admired so much about who Lester was as a person, why I wanted to play him is because in the end, he makes the right decision.
And I was like, “Sam, this is your very first movie. You’re going back to Steven Spielberg and saying, I need to re-shoot the first two days entirely?” And he went, “Yeah.” And that’s exactly what we did. A couple of weeks later, they decided that it was now a drive-through, because Annette and Peter Geller used to come into the place and ordered from the counter. Now, Sam had decided it has to be a drive-through. You have to be in the window of the drive-through, change the costumes. And we re-shot those first two days. And Sam said it was actually a moment of incredible confidence because he said the worst thing that could possibly have happened in my first two days. And after that, I was like, “I know what I’m doing. And I knew I had to re-shoot it, and it was absolutely right.”
And here’s my other little favorite story about Sam in that when we were shooting in The Valley, one of those places I flew, this was an indoor set. Sam said to me in the morning, “Hey, at lunch, I just want to record a guide track of all the dialogue, all of your narration, because they just need it in editing as a guide.” And I said, “Sure.” So I remember we came outside of this hallway where I had a dressing room in this little studio we were in, and Sam had a cassette tape recorder and a little microphone, and we put it on the floor and he pushed record. And I read the entire narration, and I never did it again.
That’s the narration in the movie, because Sam said when he listened to it, I wasn’t trying to do anything. He said, “You had no idea where these things were going, where they were going to be placed, what they were going to mean. You just read it so innocently, so purely, so directly that I knew if I brought you into a studio and put headphones on you and had you do it again, it would change the ease with which you’d done it.” And so they just fixed all of the problems that they had with this little cassette, and that is the way I did it. And the only time I did it was in this little hallway.
It was just on a wall behind me, and someone happened to zoom in on it and see it and thought, “That’s what this movie’s about. This movie’s about taking the time to look closer.” And I think that in itself is just beautiful.
And so Dick Van Dyke, who has become an extraordinary friend of mine, Dick is 98 years old, and he says, “If I’d known I was going to live this long, I would’ve taken better care of myself.” When I spend time with him, I’m just moved by every day. He gets up and he goes, “It’s a good day. I woke up.” And I learn a lot… I have a different feeling about death now than I did seven years ago, and I am on the path to being able to be in a place where I’ve resolved the things I needed to resolve, and I won’t probably get to all of it in my lifetime, but I certainly would like to be at a place where if I were to drop dead tomorrow, it would’ve been an amazing life.
So here’s what I understand, there were criminal and civil trials brought against you, including the one that started it all when Anthony Rapp sued you for $40 million. In these trials, you were acquitted, found not guilty and not liable. Is that right?
So I was often cutting dialogue because it just wasn’t needed because that relationship between… And I’d learned, that I’d experienced doing Richard III, was so extraordinary where I literally watched people, they were like, “Oh, I’m in on the thing and this is, oh, so awesome.” And then suddenly, “Wait, he killed the kids. He killed those kids in the Tower. Oh, maybe it’s not…” And you literally would watch them start to reverse their, having had such a great time with Richard III in the first three acts, I thought, “This is going to happen in this show if this intimacy can actually land.”
And I think there was some brilliant writing, and we always attempted to do it in one take. No matter how long something was, we would try to do it in one take, the direct addresses, so there was never a cut. When we went out on locations, we started to then find ways to cut it and make it slightly broader. But-
And I don’t know, a couple of weeks before we’re going to do this event, someone at the White House calls and says, “Listen, it’s very unusual to get the president for like six and a half hours. So we’re suggesting that the president come and see the first act, and then he goes.” And I knew what was happening. Now, first of all, Clinton knows this play. He knows what this play is about. And I, as gently as I could said, “Well, if the President is thinking of leaving at intermission, then I’m afraid we’re going to have to cancel the event. There’s just no way that…”
So anyway, then, “Oh no, it’s fine. It’s fine.” Now I know what was happening. What was happening was that someone had read the play and they were quite concerned. And I’ll tell you why. Because the play is about this character that I portrayed named Hickey. And in the course of the play, as things get more and more revealed, you realize that this man that I’m playing has been a philanderer. He’s cheated on his wife quite a lot, and by the end of the play, he is arrested and taken off because he ended up ending his wife’s life because she forgave him too much and he couldn’t live with it.
So now imagine this, there’s 2,000 people at the Brooks Atkinson Theater watching President Clinton watching this play. And at the end of the night we take our curtain call, they bring out the presidential podium, Bill Clinton stands up there and he says, “Well, I suppose we should all thank Kevin and this extraordinary company of actors for giving us all way too much to think about.” And the audience fell over in laughter. And then he gave a great speech. And I thought, “That was a pretty good way to handle that.”
So there are those kind of arguments that can happen. There’s different arguments on different levels, and they sometimes have to do with… I mean, look, go back to The Godfather, they wanted to fire Pacino because they didn’t see anything happening. They saw nothing happening, so they wanted to fire Pacino. And then finally Coppola thought, I’ll shoot the scene where he kills the police commissioner, and I’ll do that scene now. And that was the first scene where they went, “Yeah, actually there’s something going on there.” So Pacino kept the role.
And Jack goes, “Did we work together before?” And he says, “Yes, yes we did.” And he says, “What film did we do together?” He says, “Well, we did Missouri Breaks.” Nicholson goes, “Oh, my God, Missouri breaks, Jesus Christ, we were out of our minds on that film, holy shit. Jesus Christ, it’s a wonder I’m alive, my God, there was so much drugs going on and we were stoned out of our minds, holy shit.” Just then he folds the pants that he’s just taken off over his arm and an eighth of coke drops out onto the floor. Dennis looks at it, Nicholson looks at it, Jack goes, “Haven’t worn these pants since Missouri Breaks.”
So I went to see Hurlyburly, William Hurt, Harvey Keitel, Chris Walken, Candice Bergen, Cynthia Nixon, Jerry Stiller. And I watched this play, it’s a David Rabe play about Hollywood. And this is crazy, I mean, Bill Hurt was unbelievable. And it was extraordinary, Chris Walken, these guys… So there’s this… Harvey Keitel, and Walken came in later, Harvey Keitel’s playing this part. And I come in and I audition for it, and Nichols says, “I want you to understudy Harvey Keitel, and I want you to understudy Phil.” And I’m like, “Phil?” I mean, Harvey Keitel is in his forties, he looks like he can beat the shit out of everybody on stage, I’m this 24-year-old. And Nichols said, “It’s just all about attitude, if you believe you can beat the shit out of everybody out on stage, the audience will too.” It’s like, “Okay.”
So I then started to learn Phil. And the way it works when you’re in understudy, unless you’re a name they don’t let you rehearse on the stage, you just rehearse in a rehearsal room. But I used to sneak onto the stage, and rehearse, and try to figure out where the props were, and yada yada. Anyway, one day I get a call, “You’re going on today as Phil.” So I went on, Nichols is told by Peter Lawrence who’s the stage manager, “Spacey’s gone on as Phil.” So Nichols comes down and watches the second act, comes backstage, he says, “That was really good, how soon could you learn Mickey?” Mickey was the role that Ron Silver was playing that Chris Walken also played. I said, “I don’t know, maybe a couple weeks.” He goes, “Learn Mickey too.” So I learned Mickey, and then one day I’m told, “You’re going on tomorrow night as Mickey.”
Nichols comes, sees the second act, comes backstage, says, “That was really good. I mean, that was really funny, how soon could you learn Eddie?” And so I became the pinch hitter on Hurlyburly, I learned all the male parts, including Jerry Stiller’s, although I never went on as Jerry Stiller’s part. And then I left the play, and I guess about two months later I get this phone call from Mike Nichols, and he’s like, “Kevin, how are you?” And I’m like, “I’m fine, what can I do for you?” He says, “Well, I’m going to make a film this summer with Mandy and Meryl, and there’s a role I’d like you to come in and audition for.” So I went in, auditioned, he cast me as this mugger on a subway. Then there’s this whole upheaval that happens because he then doesn’t continue with Mandy Patinkin, Mandy leaves the movie, and he asked Jack Nicholson to come in and replace Mandy Patinkin.
So now I had no scenes with him, but I’m in a movie with Jack Nicholson and Meryl Streep, and my first scene in this movie, which I shot on my birthday, July 26th of 85′, I got to Wink at Meryl Streep in this scene. And I was so nervous I literally couldn’t wink, Nichols had to calm me down and help me wink. But that became my very first film. And he was incredible, and he let me come and watch when they were shooting scenes I wasn’t in. And I remember ending up one day in the makeup trailer, on the same day we were working, Jack and Me, we had no scene together. But I remember him coming in, and they put him down in the chair, and they put frozen cucumbers on his eyes, and did his neck, and then they raised him up and did his face. And then I remember Nicholson went like this, looked in the mirror, and he went, “Another day, another $50,000.” And walked out of the trailer.
And so somewhere in the sixties and into the seventies, my father fell in with groups of people and individuals, pretend intellectuals, who started to give him reasons why he was not successful as a white Aryan man in the United States. And over time, my father became a white supremacist. And I cannot tell you the amount of times as a young boy that my father would sit me down and lecture me for hours, and hours, and hours about his fucked up ideas of America, of prejudice, of white supremacy. And thank God for my sister who said, “Don’t listen to a thing he says, he’s out of his mind.” And even though I was young, I knew everything he was saying was against people, and I loved people. I had so many wonderful friends, my best friend Mike, who’s still my close friend to this day, I was afraid to bring him to my house because I was afraid that my father would find out he was Jewish, or that my father would leave his office door open and someone would see his Nazi flag, or his pictures of Hitler, or Nazi books, or what he might say. So when I found theater in the eighth grade, and debate club, and choir, and festivals, and plays, and everything I could do to participate in that wouldn’t make me to come back home, I did.
And I’ve reconcile who he became, because the gap between that man who was in the US Army as a medic and the man he became, I could never fill that gap. But I’ve forgiven him. But then at the same time I’ve to look at my mother and say, “She made excuses for him.” “Oh, he just needs to get it off his chest. Oh, it doesn’t matter, just let him say.” So while on the outside, I would say, “Oh, yeah, my mother loved me, but she didn’t protect me.” So was all the stuff that she expressed, and all of the attention, and all the love that I felt, was that because I became successful and I was able to fulfill an emptiness that she’d lived with her whole life with him? I don’t know, but I’ve had to ask myself those questions over these last years to try to reconcile that for myself.

The following is a conversation with Kevin Spacey, a two-time Oscar-winning actor, who has starred in Se7en, The Usual Suspects, American Beauty, and House of Cards. He is one of the greatest actors ever, creating haunting performances of characters who often embody the dark side of human nature.
The following is a conversation with Kevin Spacey, a two-time Oscar-winning actor, who has starred in Se7en, The Usual Suspects, American Beauty, and House of Cards. He is one of the greatest actors ever, creating haunting performances of characters who often embody the dark side of human nature.
Seven years ago, he was cut from House of Cards, and canceled by Hollywood and the world, when Anthony Rapp made an allegation that Kevin Spacey sexually abused him in 1986. Anthony Rapp then filed a civil lawsuit seeking $40 million. In this trial and all civil and criminal trials that followed, Kevin was acquitted. He has never been found guilty nor liable in the court of law.
In this conversation, Kevin makes clear what he did and what he didn’t do. I also encourage you to listen to Kevin’s Dan Wooten and Alison Pearson interviews, for additional details and responses to the allegations.
As an aside, let me say that one of the principles I operate under for this podcast and in life is that I will talk with everyone with empathy and with backbone. For each guest, I hope to explore their life’s work, life’s story, and what and how they think, and do so honestly and fully, the good, the bad, and the ugly, the brilliance and the flaws. I won’t whitewash their sins, but I won’t reduce them to a worse possible caricature of their sins either. The latter is what the mass hysteria of internet mobs too often does, often rushing to a final judgment before the facts are in. I will try to do better than that, to respect due process in service of the truth, and I hope to have the courage to always think independently and to speak honestly from the heart, even when the eyes of the outraged mob are on me.
Again, my goal is to understand human beings at their best and at their worst, and the hope is such understanding leads to more compassion and wisdom in the world. I will make mistakes, and when I do, I will work hard to improve. I love you all.
This is the Lex Fridman Podcast. To support it, please check out our sponsors in the description, and now, dear friends, here’s Kevin Spacey.
Seven
You played a serial killer in the movie, Se7en. Your performance was one of, if not the greatest, portrayal of a murderer on screen ever. What was your process of becoming him, John Doe, the serial killer.
Kevin Spacey
The truth is, I didn’t get the part. I had been in Los Angeles making a couple of films, Swimming With Sharks and Usual Suspects, and then I did a film called Outbreak, that Morgan Freeman was in, and I went to audition for David Fincher, in probably late November of ’94. And I auditioned for this part, and didn’t get it, and I went back to New York, and I think they started shooting like December 12th.

And I auditioned for this part, and didn’t get it, and I went back to New York, and I think they started shooting like December 12th.
And I’m in New York, I’m back in my … I have a wonderful apartment on West 12th Street, and my mom has come to visit for Christmas, and it’s December 23rd, and it’s like seven o’clock at night, and my phone rings, and it’s Arnold Kopelson, who’s the producer of Se7en, and he’s very jovial and he’s very friendly, and he says, “How are you doing?” And I said, “Fine,” and he said, “Listen, do you remember that film you came in for, Se7en?” And I said, “Yeah, yeah, absolutely.” He goes, “Well, turns out that we hired an actor and we started shooting, and then yesterday David fired him, and David would like you to get on a plane on Sunday, and come to Los Angeles and start shooting on Tuesday.” And I was like, “Okay. Would it be imposing to say, can I read it again? Because it’s been a while now, and I’d like to.” So they sent a script over. I read the script that night. I thought about it, and I had this feeling, I can’t even quite describe it, but I had this feeling that it would be really good if I didn’t take billing in the film, and the reason I felt that was because I knew that by the time this film would come out, it would be the last one of the three movies that I’d just shot, the fourth one. And if any of those films broke through or did well, if it was going to be Brad Pitt, Morgan Freeman, Gwyneth Paltrow, and Kevin Spacey, and you don’t show up for the first 25, 30, 40 minutes, people are going to figure out who you’re playing.
Lex Fridman
So people didn’t know that you play the serial killer in the movie, and the serial killer shows up more than halfway through the movie.

Kevin Spacey
Not there. And so New Cinema told me to go fuck myself, that they absolutely could use my picture and my image, and this became a little bit of a … I’d say 24 hour conversation … and it was Fincher who said, “I actually think this is a really cool idea.” So the compromise was, I’m the first credit at the end of the movie when the credits start.

David Fincher
So I got on a plane on that Sunday and I flew to Los Angeles, and I went into where they were shooting, and I went into the makeup room and David Fincher was there, and we were talking about what should I do? How should I look? And I just had my hair short for Outbreak, because I was playing a military character, and I just looked at the hairdresser and I said, do you have a razor? And Fincher went, “Are you kidding?” And I said, “No.” He goes, “If you shave your head, I’ll shave mine.” So we both shaved our heads, and then I started shooting the next day.
So my long-winded answer to your question is that I didn’t have that much time to think about how to build that character. What I think in the end, Fincher was able to do so brilliantly, with such terror, was to set the audience up to meet this character.
Lex Fridman
I think the last scene, the ending scene, and the car ride leading up to it, where it’s mostly on you in conversation with Morgan Freeman and Brad Pitt, it’s one of the greatest scenes in film history.
I think the last scene, the ending scene, and the car ride leading up to it, where it’s mostly on you in conversation with Morgan Freeman and Brad Pitt, it’s one of the greatest scenes in film history.
So people who somehow didn’t see the movie, there’s these five murders that happened that are inspired by five of the seven deadly sins, and the ending scene is inspired, represents the last two deadly sins, and there’s this calm subtlety about you in your performance, it’s just terrifying. Maybe in contrast with Brad Pitt’s performance, that’s also really strong, but that in the contrast is the terrifying sense that you get in the audience, that builds up to the twist at the end, or the surprise at the end, with the famous, “What’s in the box?” from Brad Pitt, that is Brad Pitt’s character’s wife, her head.
Kevin Spacey
Yeah. I can really only tell you that while we were shooting that scene in the car, while we were out in the desert, in that place where all those electrical wires were, David just kept saying, “Less. Do less,” and I just tried to … I remember he kept saying to me, “Remember, you are in control. You are going to win. And knowing that should allow you to have tremendous confidence,” and I just followed that lead. And I just think it’s the kind of film that so many of the elements that had been at work from the beginning of the movie, in terms of its style, in terms of how he built this terror, in terms of how he built for the audience, a sense of this person being one of the scariest people that you might ever encounter, it really allowed me to be able to not have to do that much, just say the words and mean them.

And I think it also is, it’s an example of what makes tragedy so difficult. Very often, tragedy is people operating without enough information. They don’t have all the facts. Romeo and Juliet, they don’t have all the facts. They don’t know what we know as an audience. And so in the end, whether Brad Pitt’s character ends up shooting John Doe, or turning the gun on himself, which was a discussion … there were a number of alternative endings that were discussed … nothing ends up being tied up in a nice little bow. It is complicated, and shows how nobody wins in the end when you’re not operating with all the information.
Lex Fridman
When you say, “Say the words and mean them,” what does the, “mean them,” mean?

Kevin Spacey
I’ve been very fortunate to be directed by Fincher a couple of times, and he would say to me sometimes, “I don’t believe a thing that is coming out of your mouth. Shall we try it again?” And you go, “Okay, yeah, we can try it again.” And sometimes he’ll do take, and then you’ll look to see if he has any added genius to hand you, and he just goes, “Let’s do it again,” and then, “Let’s do it again,” and sometimes … I say this in all humility … he’s literally trying to beat the acting out of you, and by continually saying, “Do it again, do it again, do it again,” and not giving you any specifics, he is systematically shredding you of all pretense, of all … because look, very often actors, we come in on the set, and we’ve thought about the scene, and we’ve worked out, “I’ve got this prop, and I’m going to do this thing with a can, and I’m going to-“. All these things, “All the tea, I’m going to do a thing with the thing,” and David is the director where he just wants you to stop adding all that crap, and just say the words, and say them quickly, and mean them. And it takes a while to get to that place.

And it takes a while to get to that place.
I’ll tell you a story. This is a story I just love, because it’s in exactly the same wheelhouse. So Jack Lemmon’s first movie was a film called It Should Happen to You, and it was directed by George Cukor. And Jack tells this story and it was just an incredibly charming story to hear Jack tell. He said, “So I am doing this picture, and let me tell you, this is a terrific part for me. And I’m doing a scene, it’s on my first day. It’s my first day, and it’s a terrific scene.” And he goes, “We do the first take, and George Cukor comes up to me and he says, ‘Jack,’ I said, ‘Yeah.’ He said, ‘Could you do, let’s do another one, but just do a little less in this one.’ And Jack said, ‘A little less? A little less than what I just did?’ He said, ‘Yeah, just a little less.'”
So he goes, “We do another take, and I think, ‘Boy, that was it. Let’s just go home,” and Cukor walked up to him. He said, “Jack, let’s do another one this time just a little bit less,” and Jack said, “Less than what I just did now?” He said, “Yeah, just a little bit less.” He goes, “Oh, okay.” So he did another take and Cukor came up and he said, “Jack, just a little bit less,” and Jack said, “A little less than what I just did?” He said, “Yes.” He goes, “Well, if I do any less, I’m not going to be acting,” and Cukor said, “Exactly, Jack. Exactly.”
Brad Pitt and Morgan Freeman
Lex Fridman
I guess what you’re saying is, it’s extremely difficult to get to the bottom of a little less, because the power, if we just stick even on Se7en, of your performances, in the tiniest of subtleties, like when you say, “Oh, you didn’t know,” and you turn your head a little bit, and a little bit, maybe a glimmer of a smile appears in your face. That’s subtlety, that’s less, that’s hard to get to, I suppose.

Kevin Spacey
Yeah, and also because I so well remember, I think the work that Brad did, and also Morgan did in that scene, but the work that Brad had to do where he had to go … I remember rehearsing with him as we were all staying at this little hotel nearby that location, and we rehearsed the night before we started shooting that sequence, and it was just incredible to see the levels of emotions he had to go through, and then the decision of, “What do I do, because if I do what he wants me to do, then he wins. But if I don’t do it, then what kind of a man, husband am I?” I just thought he did really incredible work. So it was also not easy to not react to the power of what he was throwing at me. I just thought it was a really extraordinary scene.

Lex Fridman
So what’s it like being in that scene? So it’s you, Brad Pitt, Morgan Freeman, and Brad Pitt is going over the top, just having a mental breakdown, and is weighing these extremely difficult moral choices, as you’re saying. But he’s screaming, and in pain, and tormented, while you’re very subtly smiling.

In terms of the writing and in terms of what the characters had to do, it was an incredible culmination of how this character could manipulate in the way that he did, and in the end, succeed.

You mentioned Fincher likes to do a lot of takes. That’s the famous thing about David Fincher. So what are the pros and cons of that? I think I read that he does some crazy amount. He averages 25 to 65 takes, and most directors do less than 10.

Kevin Spacey
Yeah, sometimes it’s timing, sometimes it’s literally he has a stopwatch, and he’s timing how long a scene is taking, and then he’ll say, “You need to take a minute off this scene.” ” A minute?” “Yeah, a minute off this scene. I want it to move like this. So let’s pick it up. Let’s pick up the pace. Let’s see if we can take a minute off.”

I think because Fincher hates indulgence, and he wants people to talk the way they do in life, which is we don’t take big dramatic pauses before we speak. We speak, we say what we want.

He didn’t always like the dramatic pauses. Look, you go back, any student of acting, you go back to the ’30s and the ’40s, ’50s, the speed at which actors spoke, not just in the comedies, which, of course, you look at any Preston Sturges’ movie, and it’s incredible how fast people are talking, and how funny things are when they happen that fast.

But then acting styles changed. We got into a different thing in the late ’50s and ’60s, and a lot of actors are feeling it, which I’m not saying it’s a bad thing, it’s just that if you want to keep an audience engaged, as Fincher does, and I believe successfully does in all of his work, pace, timing, movement, clarity, speed, are admirable to achieve.
Lex Fridman
In all of that, he wants the actor to be as natural as possible, to strip away all the bullshit of acting-

Look, I’ve been lucky with other directors. Sam Mendes is similar. I remember when I walked in to maybe the first rehearsal for Richard III that we were doing, and I had brought with me a canopy of ailments that my Richard was going to suffer from, and Sam eventually whittled it down to three, like, “Maybe your arm, and maybe your thing, and maybe your leg. But let’s get rid of the other 10 things that you brought into the room,” because I was so excited to capture this character.

So very often … Trevor Nunn is this way, a lot of wonderful directors I’ve worked with, they’re really good at helping you trim and edit.

David Fincher said about you … he was talking in general, I think, but also specifically in the moment of House of Cards … said that you have exceptional skill, both as an actor and as a performer, which he says are different things. So he defines the former as dramatization of a text, and the latter as the seduction of an audience.

Do you see wisdom in that distinction? And what does it take to do both the dramatization of a text and the seduction of an audience?
Kevin Spacey
Those are two very interesting descriptions. I guess, when I think performer, I tend to think entertaining. I tend to think, comedy. I tend to think, winning over an audience. I tend to think, that there’s something about that quality of wanting to have people enjoy themselves.

And when you saddle that against what maybe he means as an actor, which is more dramatic, or more text-driven more … look, I’ve always believed that my job, not every actor feels this way, but my job, the way that I’ve looked at it, is that my job is to serve the writing, and that if I serve the writing, I will in a sense serve myself, because I’ll be in the right world, I’ll be in the right context, I’ll be in the right style. I’ll have embraced what a director’s … it’s not my painting, it’s someone else’s painting. I’m a series of colors in someone else’s painting, and the barometer for me has always been, that when people stop me and talk to me about a character I’ve played, and reference their name as if they actually exist, that’s when I feel like I’ve gotten close to doing my job.
Lex Fridman
Yeah, one of the challenges for me in this conversation is remembering that your name is Kevin, not Frank or John or any of these characters, because they live deeply in the psyche.

To me, that’s the greatest compliment, for me as an actor. I love being able to go … when I think about performers who inspire me, and I remember when I was young and I was introduced to Spencer Tracy, Henry Fonda, Catherine Hepburn. I believed who they were. I knew nothing about them. They were just these extraordinary characters doing this extraordinary stuff.

And then I think more … recently contemporary, when I think of the work that Philip Seymour Hoffman did, and Heath Ledger, and people that, when I think about what they could be doing, what they could do, what they would’ve done had they stayed with us, I’m so excited when I go into a cinema, or I go into a play, and I completely am taken to some place that I believe exists, and characters that become real.
Lex Fridman
And those characters become lifelong companions. For me, they travel with you, and even if it’s the darkest aspects of human nature, they’re always there. In feel like I almost met them, and gotten to know them, and gotten to become friends with them, almost. Hannibal Lecter or Forrest Gump, I feel like I’m best friends with Forrest Gump. I know the guy, and I guess he’s played by some guy named Tom, but Forrest Gump is the guy I’m friends with.

One of the things that I feel that I try to do in my work, is when I read something for the first time, when I read a script or play, and I am absolutely devastated by it, it is the most extraordinary, the most beautiful, the most life-affirming or terrifying, it’s then a process weirdly of working backwards, because I want to work in such a way that that’s the experience I give to the audience when they first see it, that they have the experience I had when I read it.

I remember that there’s been times in the creative process when something was pointed out to me, or something was … I remember I was doing a play, and I was having this really tough time with one of the last scenes in the play, and I just couldn’t figure it out. I was in rehearsal, and although we had a director in that play, I called another, a friend of mine, who was also director, and I had him come over and I said, “Look, this scene, I’m just having the toughest, I cannot seem to crack this scene.”
And so we read it through a couple of times, and then this wonderful director named John Swanbeck, who would eventually direct me in a film called The Big Kahuna, but this is before that. He said to me the most incredible thing, he just said, “All right, what’s the last line you have in this scene before you fall over and fall asleep?” And I said, The last line is, ‘That last drink, the old KO,'” and he went, “Okay, I want you to think about what that line actually means and then work backwards.”
And so he left, and I was left with this, “What? What does that mean? How am I supposed to?” And then a couple of days went by, a couple of days went by, and I thought, “Okay, so I see that. What does that line actually mean? Well, that last drink, the old KO. KO is Knockout, which is a boxing term. It’s the only boxing term the writer uses in the play.”
And then I went back, and I realized my friend was so smart and so incredible to have said, “Ask a question you haven’t thought of asking yet.” I realized that the playwright wrote the last round, the eighth round between these two brothers, and it was a fight, physical as well as emotional. And when I brought that into the rehearsal room to the directors doing that play, he liked that idea. And we staged that scene as if it was the eighth round. The audience wouldn’t have known that, but just what I loved about that was that somebody said to me, “Ask yourself a question you haven’t asked yourself yet. What does that line mean? And then work backwards.”
Lex Fridman
What is that? Like a catalyst for thinking deeply about what is magical about this play, this story, this narrative? That’s what that is? Thinking backwards. That’s what that does?

Yeah. But also because it’s this incredible, “Why didn’t I think to ask that question myself?” That’s what you have directors for. That’s what you have … so many places where ideas can come from, but that just illustrates that even though in my brain I go, “I always like to work backwards,” I missed it in that one. And I’m very grateful to my friend for having pushed me into being able to realize what that meant, and-

To ask the interesting question. I like the poetry and the humility of, “I’m just a series of colors in someone else’s painting.” That was a good line. That said, you’ve talked about improvisation. You said that it’s all about the ability to do it again and again and again, and yet never make it the same, and you also just said that you’re trying to stay true to the text. So where’s the room for the improvisation, that it’s never the same?

Kevin Spacey
Well, there’s two slightly different contexts, I think. One is, in the rehearsal room, improvisation could be a wonderful device. Sam Mendes, for example, will start, he’ll start a scene and he does this wonderful thing. He brings rugs and he brings chairs and sofas in, and he says, “Well, let’s put two chairs here and here. You guys, let’s start in these chairs, far apart from each other. Let’s see what happens with the scene if you’re that far apart.” And so we’ll do the scene that way.

You guys, let’s start in these chairs, far apart from each other. Let’s see what happens with the scene if you’re that far apart.” And so we’ll do the scene that way.
And then he goes, “Okay, let’s bring a rug in, and let’s bring these chairs much closer, and let’s see what happens if the space between you is,” and so then you try it that way. And then it’s a little harder in Shakespeare to improv, but in any situation where you want to try and see where … where could a scene go? Where would the scene go If I didn’t make that choice? Where would the scene go? If I made this choice? Where would the scene go if I didn’t say that, or I said something else? So that’s how improv can be a valuable process to learn about limits and boundaries, and what’s going on with a character, that somehow you discover in trying something that isn’t on the page.
Then there’s the different thing, which is the trying to make it fresh and trying to make it new, and that is really a reference to theater. I’ll put it to you this way. Anybody loves sports, so you go and you watch on a pitch, you watch on a tennis game, you watch basketball, you watch football. Yeah, the rules are the same, but it’s a different game every time you’re out on that court, or on that field.
It’s no different in theater. Yes, it’s the same lines. Maybe even blocking is similar, but what’s different is attack, intention, how you are growing in a role and watching your fellow actors grow in theirs, and how every night it’s a new audience, and they’re reacting differently, and you literally … where you can go from week one of performances in a play to week 12 is extraordinary.
And the difference between theater and film is that no matter how good someone might think you are in a movie, you’ll never be any better. It’s frozen. Whereas I can be better tomorrow night than I was tonight. I can be better in a week than I was tonight. It is a living, breathing, shifting, changing, growing thing, every single day.
Lex Fridman
But also in theater, there’s no safety net. If you fuck it up, everybody gets to see you do that.

There is something of a seduction of an audience in theater, even more intense than there is when you’re talking about film. I got a chance to watch the documentary, Now in the Wings on a World Stage, which is behind the scenes of … you mentioned you teaming up with Sam Mendes in 2011 to stage Richard III, a play by William Shakespeare. I was also surprised to learn, you haven’t really done Shakespeare, or at least you said that in the movie, but there’s a lot of interesting behind-the-scenes stuff there.

First of all, the camaraderie of everybody, the bond theater creates, especially when you’re traveling. But another interesting thing you mentioned with the chairs of Sam Mendes, trying different stuff, it seemed like everybody was really open to trying stuff, embarrassing themselves, taking risks, all of that. I suppose that’s part of acting in general, but theater especially, just take risks. It’s okay to embarrass the shit out of yourself, including the director.
Kevin Spacey
And it’s also because you become a family. It’s unlike a movie, where I might have a scene with so-and-so on this day, and then another scene with them in a week and a half, and then that’s the only scenes we have in the whole movie together. Every single day, when you show up in the rehearsal room, it’s the whole company. You’re all up for it every day. You’re learning, you’re growing, you’re trying, and there is an incredible trust that happens.

And I was, of course, fortunate that some of the things I learned and observed about being a part of that family, being included in that family, and being a part of creating that family, I was able to observe from people like Jack Lemmon, who led many companies that I was fortunate to work in and be a part of.
Lex Fridman
There’s also a sad moment where at the end, everybody is really sad to say goodbye, because you do form a family and then it’s over. I guess, somebody said that that’s just part of theater. There’s a kind of assume goodbye, and that this is it.

When I first did my first episode of The Equalizer, it’s just horrible. It’s just so bad, but I didn’t know about myself, I didn’t. So slowly begin to learn about yourself, but I think good acting is good acting. And I think that if a camera’s right here, you know that your front row is also your back row. You don’t have to do so much. There is in theater, a particular kind of energy, almost like an athlete that you have to have vocally to be able to get up seven performances a week and never lose your voice and always be there and always be alive, and always be doing the best work you can that you just don’t require in film. You don’t have to have the same, it just doesn’t require the same kind of stamina that doing a play does.

Okay, that’s great. That’s good to know. You also said interesting line that improvisation helps you learn about the character. Can you explain that? So through maybe playing with the different ways of saying the words or the different ways to bring the words to life, you get to learn about yourself, about the character you’re playing.

It can be helpful, but improv is, I’m such a big believer in the writing and in serving the writing and doing the words the writer wrote that improv for me, unless you’re just doing comedy, and I mean, I love improv in comedy. It’s brilliant. So much fun to watch people just come up with something right there. But that’s where you’re looking for laughs and you’re specifically in a little scene that’s being created. But I think improv has had value, but I have not experienced it as much in doing plays as I have sometimes in doing film where you’ll start off rehearsing and a director may say, “Let’s just go off book and see what happens.” And I’ve had moments in film where someone went off book and it was terrifying.

There was a scene I had in Glengarry Glen Ross where the character I play has fucked something up, has just screwed something up. And Pacino is livid. And so we had the scene where Al is walking like this and the camera is moving with him, and he is shooing me a new asshole. And in the middle of the take, Al starts talking about me. “Oh, Kevin, you don’t think we know how you got this job? You don’t think we know whose dick you’ve been sucking on to get this part in this movie?” And I’m now, I’m literally like, I don’t know what the hell is happening, but I am reacting. We got to the end of that take. Al walked up to me and he went, “Oh, that was so good. Oh my God, that was so good. Just so you know the sound, I asked them not to record, so you have no dialogue. So it’s just me. Oh, that was so good. You look like a car wreck.” And I was like, “Yeah.” And it was actually an incredibly generous thing that he gave me so that I would react.

Well, he’s the reason I got the movie. A lot of people might think because Jack was in the film that he had something to do with it. But actually I was doing a play called Lost in Yonkers on Broadway, and we had the same dresser who worked with him, a girl named Laura, who was wonderful, Laura Beatty, and she told Al that he should come and see this play because she wanted to see me in this play. I was playing this gangster, it was a fun, fun, fun part. So I didn’t know Pacino came on some night and saw this play. And then three days later I got a call to come in and audition for this Glengary Glen Ross, which of course I knew as a play David Mamet’s play. And then I auditioned. Jamie Foley was the director who would eventually direct a bunch of House of Cards, wonderful, wonderful guy.

Jack Lemmon
And I got the part. Well, I didn’t quite get the part they were going to bring together the actors that they thought they were going to give the parts to on a Saturday at Al’s office. And they asked me if I would come and do a read through. And I said, “Who’s going to be there?” And they said, “Well, so and so and so and so,” and Jack Lemmon is flying in. And I said, “Don’t tell Mr. Lemmon that I’m doing the read through. Is that possible?” They were like, “Sure.”
So I’ll never forget this. Jack was sitting in a chair and Pacino’s office doing the New York Times crossword puzzle as he did every day. And I walked in the door and he went, “Oh, Jesus Christ, is it possible you could get a job without me? Jesus Christ, I’m so tired of holding up your end of it. Oh my God, Jesus.” So I got the job because of Pacino, and it was really one of the first major roles that I ever had in a film to be working with that group-
Lex Fridman
Yeah, that’s one of the greatest ensemble casts ever. We got Al Pacino, Jack Lemmon, Alec Baldwin, Alan Arkin, Ed Harris, you, Jonathan Pryce. It’s just incredible. And I have to say, I mean maybe you can comment. You’ve talked about how much of a mentor and a friend Jack Lemmon has been, that’s one of his greatest performances ever.

Well, by that time we had done Long Day’s Journey Into Night in the theater, we’d done a mini series called The Murder of Mary Phagan on NBC. We’d done a film called Dad that Gary David Goldberg directed with Ted Danson. So this was the fourth time we were working together and we knew each other. He’d become my father figure. And I don’t know if you know that I originally met Jack Lemmon when I was very, very young. He was doing a production at the Mark Taper Forum of a Sean O’Casey play called Juno and the Paycock with Walter Matthau and Maureen Stapleton. And on a Saturday in December of 1974, my junior high school drama class went to a workshop. It was called How to Audition. And we did this workshop, many schools in Southern California where part of this Drama Teacher’s Association. So we got these incredible experiences of being able to go see professional productions and be involved in these workshops or festivals.

And we did this workshop, many schools in Southern California where part of this Drama Teacher’s Association. So we got these incredible experiences of being able to go see professional productions and be involved in these workshops or festivals.
So I had to get up and do a monologue in front of Mr. Lemmon when I was 13 years old. And he walked up to me at the end of that and he put his hand on my shoulder and he said, “That was just actually terrific.” He said, “No, everything I’ve been talking about you just did. What’s your name?” I said, “Kevin.” He said, “Well, let me tell you something. When you get finished with high school, as I’m sure you’re going to go on and do theater, you should go to New York and you should study to be an actor, because this is what you’re meant to do with your life.” And he was like an idol.
And 12 years later, I read in the New York Times that he was coming to Broadway to do this production of A Long Day’s Journey Into Night, a year and some months after I read this article and I was like, “I’m going to play Jamie in that production.” And I then with a lot of opposition because the casting director didn’t want to see me. They said that the director, Jonathan Miller wanted movie actors to play the two sons. And ultimately, I found out that Jonathan Miller, the director, was coming to New York to do a series of lectures at Alice Tully Hall. And I went to try to figure out how I could maybe meet him. And I was sitting in that theater listening to this incredible lecture he was doing. And sitting next to me was an elderly woman. I mean elderly, 80 something and she was asleep, but sticking out of her handbag, which was on the floor, was a invitation to a cocktail reception in honor of Dr. Jonathan Miller.
And so I thought, “She’s tired. She’s probably going to go home.” So I took that and walked into this cocktail reception and ultimately went over to Dr. Miller who was incredibly kind and said, “Sit down. I’m always very curious what brings young people to my lectures.” And I said to him, “Eugene O’Neill brought me here.” And he was like, “What? I’ve always wanted to meet him. Where is he?” And I told him that I’ve been trying for seven months to get an audition for A Long Day’s Journey, and that his American cast directors were telling my agents that he wanted big American movie stars. And at that moment, he turned and he saw one of those casting directors who was there that night, because I knew he was going to be in New York starting auditions that week.
And she was staring daggers at me and he just got it. And he said, “Does someone have a pen?” And he took a little paper, started writing. He said, “Listen, Kevin, there are many situations in which casting directors have a lot of say and a lot of power and a lot of leverage. And then there are other situations where they just take director’s messages. And on this one, they’re taking my messages, this is where I’m staying, make sure your people get to me. We start auditions on Thursday.” And on Thursday I had an opportunity to come in and audition for this play that I’d been working on and preparing. And at the end of it, I did four scenes. At the end of it, he said to me that unless someone else came in and blew him against the wall, I had just done as far as he was concerned, I pretty much had the part, but I couldn’t tell my agents that yet because I had to come back and read with Mr. Lemmon.
And so three months later, in August of 1985, I found myself in a room with Jack Lemmon again at 890 Broadway, which is where they rehearse a lot of the Broadway plays. And we did four scenes together, and I was toppling over him. I was pushing him, I was relentless. And I’ll never forget, at the end of that, Lemmon came over to me, he put his hand on my shoulder and he said, “That was, your touch was terrific, I never thought we’d find the rotten kid, but he’s it. Jesus Christ. What the hell was that?” And I ended up spending the next year of my life with that man.

This world works in mysterious ways. It also speaks to the fact of the power of somebody you look up to giving words of encouragement, because those can just reverberate through your whole life and just make the path clear.

I’ve always, we used to joke that if every contract came with a Jack Lemmon clause, it would be a more beautiful world.

Beautifully said, Jack Lemmon is one of the greatest actors ever. What do you think makes him so damn good?

Wow. I think he truly set out in his life to accomplish what his father said to him on his deathbed. His father was dying. His father was, by the way, called the Donut King in Boston, and not in the entertainment business at all. He was literally owned a donut company. And when he was passing away, Jack said, “The last thing my father said to me was, go out there and spread a little sunshine.” And I truly think that’s what Jack loved to do.

American Beauty
I remember this, and I don’t know if this will answer your question, but I think it’s revealing about what he’s able to do and what he was able to do and how that ultimately influenced what I was able to do. Sam Mendes had never directed a film before American Beauty. So what he did was he took the best elements of theater and applied them to the process. So we rehearsed it like a play in a sound stage where everything was laid out, like it would be in a play and this couch will be here. And he’d sent me a couple of tapes. He’d sent me two cassette tapes, one that he’d like to call pre-Lester before he begins to move in a new direction. And then post-Lester, and they just were different songs. And then he said to me one day, and I think always thought this was brilliant of Sam to use Lemmon knowing what Lemmon meant to me.
He said, “When was the last time you watched The Apartment?” And I said, “I don’t know. I mean, I love that movie so much.” He goes, “I want you to watch it again and then let’s talk.” So I went and I watched the movie again, and we sat down and Sam said, “What Lemmon does in that film is incredible because there is never a moment in the movie where we see him change. He just evolves and he becomes the man he becomes because of the experiences that he has through the course of the film. But there’s this remarkable consistency in who he becomes, and that’s what I need you to do as Lester, I don’t want the audience to ever see him change. I want him to evolve.
And so we did some, I mean, first of all, it was just a great direction. And then second of all, we did some things that people don’t know we did to aid that gradual shift of that man’s character. First of all, I had to be in the best shape from the beginning of the movie. We didn’t shoot in sequence. So I was in this crazy shape. I had this wonderful trainer named Mike Torsha, who just was incredible. But so what we did was, in order to then show this gradual shift was I had three different hair pieces.
I had three different kinds of costumes of different colors and sizes, and I had different makeup. So in the beginning, I was wearing a kind of drab, dull, slightly uninspired hair piece, and my makeup was kind of gray and boring, and I was a little bit, there were times when I was too much like this. And Sam would go, “Kevin, you look like Walter Matthau. Would you please stand up a little bit?” We’re sort of midway through at this point. And then at a certain point, the wig changed and it had little highlights in it, a little more color, a little more, the makeup became a little, the suits got a little tighter. And then finally a third wig that was golden highlights and sunshine and rosy cheeks and tight fit. And these are what we call theatrical tricks. This is how an audience doesn’t even know it’s happening, but it is this gradual.
And I just always felt that that was such a brilliant way because he knew what I felt about Jack. And when you watch The Apartment, it is extraordinary that he doesn’t ever change. He just… So I’m, and in fact, I thanked Jack when I won the Oscar and I did my thank you speech, and I walked off stage, and I remember I had to sit down for a moment because I didn’t want to go to the press room because I wanted to see if Sam was going to win. And so I was waiting and my phone rang and it was Lemmon. He said, “You’re a son of a bitch.” I said, “What?” He goes, “First of all, congratulations and thanks for thanking me, because God knows you couldn’t have done it without me.” He said, “Second of all,” he said, “Do you know how long it took me to win from supporting actor? I won for Mr. Roberts, and it took me like 10, 12 years to win Oscar. You did it in four, you son of a bitch.”
Lex Fridman
Yeah. The Apartment was, I mean, it’s widely considered one of the greatest movies ever. People sometimes refer to it as the comedy, which is an interesting kind of classification. I suppose that’s a lesson about comedy, that the best comedy is the one that’s basically a tragedy.

I mean, yeah. What’s that line between comedy and tragedy for you?
Kevin Spacey
Well, if it’s a line, it’s a line I cross all the time because I’ve tried always to find the humor, unexpected sometimes, maybe inappropriate sometimes, maybe shocking. But I’ve tried in I think almost every dramatic role I’ve had to have a sense of humor and to be able to bring that along with everything else that is serious, because frankly, that’s how we deal with stuff in life.

Sure. Well, I mean, it’s like the great Mary Tyler Moore Show where they can’t stop giggling at the clown’s funeral. I mean, it’s just one of the great episodes ever. Giggling at a funeral is as bad as farting at a funeral. And I’m sure that there’s some people who have done both.

Oh, man. So you mentioned American Beauty and the idea of not changing, but evolving. That’s really interesting because that movie is about finding yourself. It’s a philosophically profound movie. It’s about various characters in their own ways, finding their own identity in a world where maybe a system, a materialistic system that wants you to be like everyone else. And so, I mean, Lester really transforms himself throughout the movie. And you’re saying the challenge there is to still be the same human being fundamentally.

Yeah, and I also think that the film was powerful because you had three very honest and genuine portrayal of young people, and then you had Lester behaving like a young person doing things that were unexpected. And I think that the honesty with which it dealt with those issues that those teenagers were going through, and the honesty with which it dealt with what Lester was going through, I think are some of the reasons why the film had the response that it did from so many people.

I mean, I used to get stopped and someone would say to me, “When I first saw American Beauty, I was married, and the second time I saw it, I wasn’t.” I was like, “Well, we weren’t trying to increase the divorce rate. It wasn’t our intention.” But it is interesting how so many people have those kinds of crazy fantasies. And what I admired so much about who Lester was as a person, why I wanted to play him is because in the end, he makes the right decision.
Lex Fridman
I think a lot of people live lives of quiet desperation in a job they don’t like in a marriage they’re unhappy in. And to see somebody living that life and then saying, “Fuck it,” in every way possible, and not just in a cynical way, but in a way that opens Lester up to see the beauty in the world. That’s the beauty in American Beauty.

And in that, there’s a bunch of humor also in the anger, in the absurdity of taking a stand against the conformity of life. There’s this humor, and I read somewhere that the scene, the dinner scene, which is kind of play-like where Lester slams the plate against the wall was improvised by you, the slamming of the plate against the wall.

Where else? Yellowstone was another situation where it’s a family at the dinner table, and then one of them says, “Fuck it, I’m not eating this anymore and I’m going to create a scene.” It’s a beautiful kind of environment for dramatic scenes.

Well, with Annette, I just adored working with her. And we were the two actors that Sam wanted from the very beginning, much against the will of the higher-ups who wanted other actors to play those roles. But I’ve known Annette since we did a screen test together from Miloš Forman for a film he did of the Les Leves En Dangerous movie. It was a different film from that one, but it was the same story. And I’ve always thought she is just remarkable. And I think that the work she did in that film, the relationship that we were able to build, for me, the saddest part of that success was that she didn’t win the Oscar, and I felt she should have.

Yeah. And I guess it was maybe the third day or the fourth day of shooting. We’d now done that. And I said to Sam, “So how are the dailies? How do they look?” He goes, “Which ones?” I said, “Well, the first Smiley’s.” He goes, “Oh, they’re shit.” And I went, “Yeah, no, how were they?” He goes, ” No, they’re shit. I hate them. I hate everything about them. I hate the costumes. I hate the location. I hate that you’re inside. I hate the way you acted. I hate everything but the script. So I’ve gone back to the studio and asked them if we can re-shoot the first two days.”

So I’ve gone back to the studio and asked them if we can re-shoot the first two days.”
And I was like, “Sam, this is your very first movie. You’re going back to Steven Spielberg and saying, I need to re-shoot the first two days entirely?” And he went, “Yeah.” And that’s exactly what we did. A couple of weeks later, they decided that it was now a drive-through, because Annette and Peter Geller used to come into the place and ordered from the counter. Now, Sam had decided it has to be a drive-through. You have to be in the window of the drive-through, change the costumes. And we re-shot those first two days. And Sam said it was actually a moment of incredible confidence because he said the worst thing that could possibly have happened in my first two days. And after that, I was like, “I know what I’m doing. And I knew I had to re-shoot it, and it was absolutely right.”
Lex Fridman
And I guess that’s what a great director must do, is have the guts in that moment to re-shoot everything. That’s a pretty gutsy move.

And I used to fly in my dreams, those opening shots over the neighborhood? I used to come into those shots in my bathrobe flying, and then when I hit the ground and the newspaper was thrown at me by the newspaper guy and I caught it, the alarm would go off, and I wake up in bed. I spent five days being hung by wires and filming these sequences of flying through my dreams. And Sam said to me, “Yeah, the flying sequences are all gone and the trial is gone.” And I was like, “What are you talking about?”

And Sam said to me, “Yeah, the flying sequences are all gone and the trial is gone.” And I was like, “What are you talking about?”
And here’s my other little favorite story about Sam in that when we were shooting in The Valley, one of those places I flew, this was an indoor set. Sam said to me in the morning, “Hey, at lunch, I just want to record a guide track of all the dialogue, all of your narration, because they just need it in editing as a guide.” And I said, “Sure.” So I remember we came outside of this hallway where I had a dressing room in this little studio we were in, and Sam had a cassette tape recorder and a little microphone, and we put it on the floor and he pushed record. And I read the entire narration, and I never did it again.
That’s the narration in the movie, because Sam said when he listened to it, I wasn’t trying to do anything. He said, “You had no idea where these things were going, where they were going to be placed, what they were going to mean. You just read it so innocently, so purely, so directly that I knew if I brought you into a studio and put headphones on you and had you do it again, it would change the ease with which you’d done it.” And so they just fixed all of the problems that they had with this little cassette, and that is the way I did it. And the only time I did it was in this little hallway.

Yeah, and in fact, I’ll even tell you something that I always thought was so incredible. When we shot the scenes in the office where Lester worked, the job he hated, there was a bulletin board behind me on a wall, and someone who was watching a cut or early dailies who was in the marketing department saw that someone had cut out a little piece of paper and stuck it and it said, “Look closer.” And they presented that to Sam as the idea of what that could go on the poster, the idea of looking closer was such a brilliant idea, but I mean, it wasn’t like, wasn’t in the script.

It was just on a wall behind me, and someone happened to zoom in on it and see it and thought, “That’s what this movie’s about. This movie’s about taking the time to look closer.” And I think that in itself is just beautiful.

And so Dick Van Dyke, who has become an extraordinary friend of mine, Dick is 98 years old, and he says, “If I’d known I was going to live this long, I would’ve taken better care of myself.” When I spend time with him, I’m just moved by every day. He gets up and he goes, “It’s a good day. I woke up.” And I learn a lot… I have a different feeling about death now than I did seven years ago, and I am on the path to being able to be in a place where I’ve resolved the things I needed to resolve, and I won’t probably get to all of it in my lifetime, but I certainly would like to be at a place where if I were to drop dead tomorrow, it would’ve been an amazing life.

So let’s talk about it. Let’s talk about this dark time. Let’s talk about the sexual allegations against you that led to you being canceled by, well, the entire world for the last seven years. I would like to personally understand the sins, the bad things you did, and the bad things you didn’t do. So I also should say that the thing I hope to do here is to give respect to due process, innocent until proven guilty, that the mass hysteria machine of the internet and click bait journalism doesn’t do.

Yes.
Yes.
Lex Fridman
I think that’s really important, again, in terms of due process. I read a lot and I watched a lot in preparation for this, on this point, including of course the recently detailed interviews you did with Dan Wooten and then Allison Pearson of The Telegraph, and those were all focused on this topic and they go in detail where you respond in detail to many of the allegations. If people are interested in the details, they can listen to those. So based on that, and everything I looked at, as I understand, you never prevented anyone from leaving if they wanted to, sort of in the sexual context, for example, by blocking the door. Is that right?

I did a lot of horsing around. I did a lot of things that at the time I thought were sort of playful and fun, and I have learned since were not. And I have had to recognize that I crossed some boundaries and I did some things that were wrong and I made some mistakes, and that’s in my past. I mean, I’ve been working so hard over these last seven years to have the conversations I needed to have, to listen to people, to understand things from a different perspective than the one that I had and to say, “I will never behave that way again for the rest of my life.”

Just to clarify, I think you are often too pushy with the flirting and that manifests itself in multiple ways. Just to make clear, you never prevented anyone from leaving if they wanted to. You always took the explicit, “No” from people as an answer. “No, stop.” You took that for the answer. You’ve never done anything sexual with an underage person and you’ve never explicitly offered to exchange sexual favors for career advancement. These are some of the accusations that have been made and in the court of law multiple times have been shown not to be true.

But I have had a sexual life and I’ve fallen in love and I’ve been so admiring of people that I… I’m so romantic. I’m such a romantic person that there’s this whole side of me that hasn’t been talked about, isn’t being discussed, but that’s who I know. That’s the person I know. It’s been very upsetting to hear that some people have said, I mean, I don’t have a violent bone in my body, but to hear people describe things as having been very aggressive is incredibly difficult for me. And I’m deeply sorry that I ever offended anyone or hurt anyone in any way. It is crushing to me, and I have to work very hard to show and to prove that I have learned. I got the memo and I will never, ever, ever behave in those ways again.

From everything I’ve seen in public interactions with you people love you, colleagues love you, coworkers love you. There’s a flirtatiousness. Another word for that is chemistry. There’s a chemistry between the people you work with.

And by the way, not to take anything away from my accountability for things I did where I got it wrong, I crossed the line, I pushed some boundaries. I accept all of that, but I live in an industry in which flirtation, attraction, people meeting in the workspace and ending up marrying each other and having children. And so it is a space and a place where these notions of family, these notions of attraction, these notions of… It’s always complicated if you meet someone in the workspace and find yourselves attracted to each other. You have to be mindful of that, and you have to be very mindful that you don’t ever want anyone to feel that their job is in jeopardy or you would punish them in some way if they no longer wanted to be with you. So those are important things to just acknowledge.

Another complexity to this, as I’ve seen, is that there’s just a huge number of actors that look up to you, a huge number of people in the industry that look up to you and love you. I’ve seen just from this documentary, just a lot of people just love being around you, learning from you what it means to create great theater, great film, great stories. And so that adds to the complexity. I wouldn’t say it’s a power dynamic like a boss-employee relationship. It’s an admiration dynamic that is easy to miss and easy to take advantage of. Is that something you understand?

Yes. And I also understand that there are people who met me and spent a very brief period of time with me, but presumed I was now going to be their mentor and then behaved in a way that I was unaware of, that they were either participating or flirting along or encouraging me without me having any idea that at the end of the day they were expecting something. So these are about relationships. These are about two people. These are about people making decisions, people making choices, and I accept my accountability in that. But there are a number of things that I’ve been accused of that just simply did not happen, and I can’t say, and I don’t think it would be right for me to say, “Well, everything that’s ever been I’ve been accused of is true,” because we’ve now proved that it isn’t and it wasn’t. But I’m perfectly willing to accept that I had behaviors that were wrong and that I shouldn’t have done, and I am regretful for.

I think that also speaks to a dark side of fame. The sense I got is that there are some people, potentially a lot of people, trying to make friends with you in order to get roles, in order to advance their career. So not you using them, but they trying to use you. What’s that like? How do you know if somebody likes you for you, for Kevin, or likes you for, you said you’re a romantic, you see a person and you’re like, “I like this person,” and they seem to like you. How do you know if they like you for you?

Well, to some degree I would say that I have been able to trust my instincts on that and that I’ve most of the time been right. But obviously in the last number of years, not just with people who’ve accused me, but just also people in my own industry to realize that, “Oh, I thought we had a friendship, but I guess that was about an inch thick and not what I thought it was.” But look, one shouldn’t be surprised by that. I have to also say, you said a little while ago that the world had canceled me, and I have to disagree with you. I have to disagree because for seven years I’ve been stopped by people sometimes every day, sometimes multiple, multiple times a day. And the conversations that I have with people, the generosity that they share, the kindness that they show and how much they want to know when I’m getting back to work tells me that while there may be a very loud minority, there is a quieter majority.

I think if I were to go back that far, I probably would’ve found a way to not have been as concerned about revealing my sexuality and hiding that for as long as I did. I think that had a lot to do with confusion and a lot to do with mistrust, both my own and other people’s.

Ian McKellen said, after 40, he was 49 when he came out. 27 years he’d been a professional actor being in the closet. And he said he felt it was like he was living a part of his life not being truthful, and that he felt that it affected his work when he did come out because he no longer felt like he had anything to hide. And I absolutely believe that that is what my experience has been and will continue to be. I’m sorry about the way I came out, but Evan and I had already had the conversation. I had already decided to come out, and so it wasn’t like, “Oh, I was forced to come out,” but it was something I decided to do. And by the way, much against Evan’s advice, I came out in that statement and he wishes that I had not done so.

No, I basically said that I didn’t remember what this person was, what Anthony Rapp was claiming from 31 years before. I had no memory of it, but if it had happened, if this embarrassing moment had happened, then I would owe him an apology. That was what I said, and then I said, “And while I’m at it, I think I’ll come out.” And it was definitely not the greatest coming out party ever. I will admit that.

Well, from the public perception, the first part of that. So first of all, the second part is a horrible way to come out. Yes, we all agree. And then the first part from the public viewpoint, they see guilt in that which also is tragic because at least that particular accusation, and it’s a very dramatic one, it’s a $40 million lawsuit, it’s a big deal, and an underage person, was shown to be false.

Well, but you’re melding two things together. The lawsuit didn’t happen until 2020 and then it didn’t get to court until 2022. We’re back in 2017 when it was just an accusation he made in BuzzFeed Magazine. Look, I was backed into a corner. When someone says, “You were so drunk, you won’t remember this thing happened,” what’s your first instinct? Is your first instinct to say, “This person’s a liar”? Or is your first instinct to go, “What? I was what? 31 years at a party I don’t even remember throwing?” Obviously a lot of investigation happened after that in which we were then able to prove in that court case that it had never occurred. But at the moment, I was sort of being told I couldn’t push back. You have to be kind. You can’t… I think even to me now, none of it sounds right. But I don’t know that I could have said anything that would’ve been satisfactory to anybody.

A lot of people who know you, and some of whom I know who have worked with you privately, show support for you, but are afraid to speak up publicly. What do you make of that? I mean, to me personally, this just makes me sad because perhaps that’s the nature of the industry that it’s difficult to do that, but I just wish there would be a little bit more courage in the world.

House of Cards
Lex Fridman
So as you said, your darkest moment in 2017, when all of this went down, one of the things that happened is you were no longer on House of Cards for the last season. Let’s go to the beginning of that show, one of the greatest TV series of all time, a dark fascinating character in Frank Underwood, a ruthless, cunning, borderline evil politician. What are some interesting aspects to the process you went through for becoming Frank Underwood? Maybe Richard III. There’s a lot of elements there in your performance that maybe inspired that character. Is that fair or no?

Kevin Spacey
I’ll give you one very interesting, specific education that I got in doing Richard III and closing that show at BAM in March of 2012, and two months later started shooting House of Cards. There is something called direct address. In Shakespeare you have Hamlet, talks to the world. But when Shakespeare wrote Richard III, it was the first time he created something called direct address, which is the character looks directly at each person close by. It is a different kind of sharing than when a character’s doing a monologue. Opening of Henry IV. And while there are some people who believe that direct address was invented in Ferris Bueller, it wasn’t. It was Shakespeare who invented it. So I had just had this experience every night in theaters all over the world, seeing how people reacted to becoming a co-conspirator, because that’s what it’s about. And what I tried to do and what Fincher really helped me with in those beginning days was how to look in that camera and imagine I was talking to my best friend.

Kevin Spacey
Yeah. And there were many times when I suppose the writers thought I was crazy, where I would see a script and I would see this moment where this direct address would happen, I’d say all this stuff, and I’d go, when we’d do a read through of the script, I go, “I don’t think I need to say any of that.” And they were like, “What do you mean?” I said, “Well, the audience knows all of that. All I have to do is look. They know exactly what’s going on. I don’t need to say a thing.”
Yeah. And there were many times when I suppose the writers thought I was crazy, where I would see a script and I would see this moment where this direct address would happen, I’d say all this stuff, and I’d go, when we’d do a read through of the script, I go, “I don’t think I need to say any of that.” And they were like, “What do you mean?” I said, “Well, the audience knows all of that. All I have to do is look. They know exactly what’s going on. I don’t need to say a thing.”
So I was often cutting dialogue because it just wasn’t needed because that relationship between… And I’d learned, that I’d experienced doing Richard III, was so extraordinary where I literally watched people, they were like, “Oh, I’m in on the thing and this is, oh, so awesome.” And then suddenly, “Wait, he killed the kids. He killed those kids in the Tower. Oh, maybe it’s not…” And you literally would watch them start to reverse their, having had such a great time with Richard III in the first three acts, I thought, “This is going to happen in this show if this intimacy can actually land.”
And I think there was some brilliant writing, and we always attempted to do it in one take. No matter how long something was, we would try to do it in one take, the direct addresses, so there was never a cut. When we went out on locations, we started to then find ways to cut it and make it slightly broader. But-
Lex Fridman
That’s interesting because you’re doing a bunch of, with both Richard III and Frank Underwood, a bunch of dark, borderline evil things. And then I guess the idea is you’re going to be losing the audience and then you win them back over with the addresses.

Yeah. Well, in that production that’s absolutely true. Also, Richard is one of the weirder… Weird. I mean by weird, was an early play of Shakespeare’s. And he’s basically never off stage. I mean, I remember when we did the first run through, I had no idea what the next scene was. Every time I came off stage, I had no idea what was next. They literally had to drag me from one place to another scene. “Now it’s the scene with Hastings,” but I now understand these wonderful stories that you can read in old books about Shakespeare’s time, that actors grabbed Shakespeare around the cuff and punched him and threw him against a wall and said, “You ever write a part like this again? I’m going to kill you.” And that’s why in later plays, he started to have a pageant happened, and then a wedding happened and the main character was off stage resting because the actor had said, “You can’t do this to us. There’s no breaks.” And it’s true, there’s very few breaks in Richard III. You’re on stage most of the time.

I’m going to kill you.” And that’s why in later plays, he started to have a pageant happened, and then a wedding happened and the main character was off stage resting because the actor had said, “You can’t do this to us. There’s no breaks.” And it’s true, there’s very few breaks in Richard III. You’re on stage most of the time.
Lex Fridman
The comedic aspect of Richard III and Frank Underwood, is that a component that helps bring out the full complexity of the darkness that is Frank Underwood.

I certainly can’t take credit for Shakespeare having written something that is funny or Beau Willimon and his team to have written something that is funny. It’s fundamentally funny. It just depends on how I interpret it. That’s one of the great things why we love in a year’s time, we can see five different Hamlets. We can see four Richard IIIs, we can see two Richard IIs. That’s part of the thrill, that we don’t own these parts. We borrow them and we interpret them. And what Ian McKellen might do with a role could be completely different from what I might do because of the way we perceive it. And also very often in terms of going for humor, it’s very often a director will say, “Why don’t you say that with a bit of irony? Why don’t you try that with a bit of blah, blah, blah?”

Yeah. There’s often a wry smile. The line that jumps to me, when you’re talking about Claire in the early, maybe first episode even, “I love that woman more than sharks love blood.” I guess there’s a lot of ways to read that line, but the way you read it had both humor, had legitimate affection, had all the ambition and narcissism, all of that mixed up together.

I also think that one should just acknowledge that where he was from. There is something that happens when you do an accent. And in fact, sometimes when I would say to Beau or one of the other writers, “This is really good and I love the idea, but it rhythmically doesn’t help. I need at least two more words to rhythmically make this work in his accent because it just doesn’t scan.” And that’s not iambic pentameter. I’m not talking about that. There is that as well in Shakespeare. But there was sometimes when it’s too many lines, it’s not enough lines, in order for me to make this work for the way he speaks, the way he sounds and what that accent does to emphasis.

How much of that character in terms of the musicality of the way he speaks, is Bill Clinton?
How much of that character in terms of the musicality of the way he speaks, is Bill Clinton?
Kevin Spacey
Not really at all. I mean, Clinton, look, Bill Clinton, he had a way of talking, that he was very slow and he felt your pain. But Frank Underwood was deeper, more direct and less poetic in the way that Clinton would talk. I’ll tell you this Clinton story that you’ll like. So we decide to do a performance of The Iceman Cometh for the Democratic Party on Broadway. And the President is going to come, he’s going to see this four and a half hour play. And then we’re going to do this event afterward.

So we decide to do a performance of The Iceman Cometh for the Democratic Party on Broadway. And the President is going to come, he’s going to see this four and a half hour play. And then we’re going to do this event afterward.
And I don’t know, a couple of weeks before we’re going to do this event, someone at the White House calls and says, “Listen, it’s very unusual to get the president for like six and a half hours. So we’re suggesting that the president come and see the first act, and then he goes.” And I knew what was happening. Now, first of all, Clinton knows this play. He knows what this play is about. And I, as gently as I could said, “Well, if the President is thinking of leaving at intermission, then I’m afraid we’re going to have to cancel the event. There’s just no way that…”
So anyway, then, “Oh no, it’s fine. It’s fine.” Now I know what was happening. What was happening was that someone had read the play and they were quite concerned. And I’ll tell you why. Because the play is about this character that I portrayed named Hickey. And in the course of the play, as things get more and more revealed, you realize that this man that I’m playing has been a philanderer. He’s cheated on his wife quite a lot, and by the end of the play, he is arrested and taken off because he ended up ending his wife’s life because she forgave him too much and he couldn’t live with it.
So now imagine this, there’s 2,000 people at the Brooks Atkinson Theater watching President Clinton watching this play. And at the end of the night we take our curtain call, they bring out the presidential podium, Bill Clinton stands up there and he says, “Well, I suppose we should all thank Kevin and this extraordinary company of actors for giving us all way too much to think about.” And the audience fell over in laughter. And then he gave a great speech. And I thought, “That was a pretty good way to handle that.”
Lex Fridman
Well, in that way, him and Frank Underwood share like a charisma. There’s certain presidents that just have, politicians that just have this charisma. You can’t stop listening to them. Some of it is the accent, but some of it is some other magical thing.

I give him a huge amount of the credit, and not just for what he established, but the fact that every director after stayed within that world. I think that’s why the series had a very consistent feeling to it. It was like watching a very long movie. The style, where the camera went, what it did, what it didn’t do, how we used this, how we used that, how we didn’t do this. There were things that he laid the foundation for that we managed to maintain pretty much until Beau Willimon left the show. They got rid of Fincher. And I was sort of the last man standing in terms of fighting against… Netflix had never had any creative control at all. We had complete creative control, but over time they started to get themselves involved because look, this is what happens to networks. They’d never made a television show before, ever. And then.

They’d never made a television show before, ever. And then four years later, they were the best. And so then you’re going to get suggestions about casting, and about writing, and about music and scenes. And so there was a considerable amount of pushback that I had to do when they started to get involved in ways that I thought was affecting the quality of the show.

What are those battles like? I heard that there was a battle with the execs, like you mentioned early on about your name not being on the billing for Seven. I heard that there’s battles about the ending of Seven, which was really… Well, it was pretty dark. So what’s that battle like? How often does that happen, and how do you win that battle? Because it feels like there’s a line where the networks or the execs are really afraid of crossing that line into this strange, uncomfortable place, and then great directors and great actors kind of flirt with that line.

It can happen in different ways. I mean, I remember a argument we had was we had specifically shot a scene so that there would be no score in that scene, so that there was no music, it was just two people talking. And then we end up seeing a cut where they’ve decided to put music in, and it is against everything that scene’s supposed to be about. And you have to go and say, “Guys, this was intentional, we did not want score. And now you’ve added score, because what? You think it’s too quiet. You think our audience can’t listen to two people talk for two and a half minutes? This show has proved anything, it’s proved that people have patience and they’re willing to watch an entire season over a weekend.”

So there are those kind of arguments that can happen. There’s different arguments on different levels, and they sometimes have to do with… I mean, look, go back to The Godfather, they wanted to fire Pacino because they didn’t see anything happening. They saw nothing happening, so they wanted to fire Pacino. And then finally Coppola thought, I’ll shoot the scene where he kills the police commissioner, and I’ll do that scene now. And that was the first scene where they went, “Yeah, actually there’s something going on there.” So Pacino kept the role.
Lex Fridman
Do you think that Godfather’s when the Pacino we know was born? Or is that more like there’s the character that really over the top in Scent of a Woman? There’s stages, I suppose.

Yeah, of course. Look, I think that we can’t forget that Pacino is also an animal of the theater. He does a lot of plays, and he started off doing plays, and movies were… Panic in Needle Park was his first. And yeah, I think there’s that period of time when he was doing some incredible parts, incredible movies. When I did a series called Wiseguy, I got cast on a Thursday, and I flew up to Vancouver on a Saturday, and I started shooting on Monday. And all I had time to do was watch The Godfather and Serpico, and then I went to work.

I was going to mention when we’re talking Seven, that just if you’re looking at the greatest performances, portrayals of murderers. So obviously, like I mentioned, Hannibal Lecter in Silence of the Lambs, that’s up there. Seven to me is competing for first place with Silence of the Lambs. But then there’s a different one with Kubrick and Jack Nicholson with The Shining. And there as opposed to a murderer who’s always been a murderer, here’s a person, like in American Beauty, who becomes that, who descends into madness. I read also that Jack Nicholson improvised, “Here’s Johnny.” In that scene.

The story was told to a soundman, Dennis Maitland, who’s a great, great, great guy. He said he was very excited because he got on Prizzi’s Honor, which was Jack Nicholson and Anjelica Huston, directed by John Houston. And he said, “I was so excited. It was my first day on the movie, and I get told to go into Mr. Nicholson’s trailer and mic him up for the first scene. So I knock on the trailer door and I hear, yes, and come on in. And I come inside and Mr. Nicholson is changing out of his regular clothes, and he’s going to put on his costume. And so I’m setting up the mic, and I’m getting ready. And I said, Mr. Nicholson, I just wanted to tell you I’m extremely excited to be working with you again, it’s a great pleasure.”

And Jack goes, “Did we work together before?” And he says, “Yes, yes we did.” And he says, “What film did we do together?” He says, “Well, we did Missouri Breaks.” Nicholson goes, “Oh, my God, Missouri breaks, Jesus Christ, we were out of our minds on that film, holy shit. Jesus Christ, it’s a wonder I’m alive, my God, there was so much drugs going on and we were stoned out of our minds, holy shit.” Just then he folds the pants that he’s just taken off over his arm and an eighth of coke drops out onto the floor. Dennis looks at it, Nicholson looks at it, Jack goes, “Haven’t worn these pants since Missouri Breaks.”

I think it was… Yeah, it was 1984, I went into audition for the national tour of a play called The Real Thing, which Jeremy Irons and Glenn Close were doing on Broadway that Mr. Nichols had directed. So I went in to read for this character, Brodie, who is a Scottish character. And I did the audition, and Mike Nichols comes down the aisle of the theater, and he’s asking me questions about, “Where’d you go to school?” And, “What have you been doing?” I just come back from doing a bunch of years of regional theater and different theaters, so I was in New York, and meeting Mike Nichols was just incredible. So Mr. Nichols went, “Have you seen the other play that I directed up the block called Hurlyburly?” And I said, “No, I haven’t.” And he says, “Why not?” I said, “I can’t afford a Broadway ticket.” He said, “We can arrange that. I’d like you to go see that play, and then I’d like you to come in next week and audition for that.” And I was like, “Okay.”

I’d like you to go see that play, and then I’d like you to come in next week and audition for that.” And I was like, “Okay.”
So I went to see Hurlyburly, William Hurt, Harvey Keitel, Chris Walken, Candice Bergen, Cynthia Nixon, Jerry Stiller. And I watched this play, it’s a David Rabe play about Hollywood. And this is crazy, I mean, Bill Hurt was unbelievable. And it was extraordinary, Chris Walken, these guys… So there’s this… Harvey Keitel, and Walken came in later, Harvey Keitel’s playing this part. And I come in and I audition for it, and Nichols says, “I want you to understudy Harvey Keitel, and I want you to understudy Phil.” And I’m like, “Phil?” I mean, Harvey Keitel is in his forties, he looks like he can beat the shit out of everybody on stage, I’m this 24-year-old. And Nichols said, “It’s just all about attitude, if you believe you can beat the shit out of everybody out on stage, the audience will too.” It’s like, “Okay.”
So I then started to learn Phil. And the way it works when you’re in understudy, unless you’re a name they don’t let you rehearse on the stage, you just rehearse in a rehearsal room. But I used to sneak onto the stage, and rehearse, and try to figure out where the props were, and yada yada. Anyway, one day I get a call, “You’re going on today as Phil.” So I went on, Nichols is told by Peter Lawrence who’s the stage manager, “Spacey’s gone on as Phil.” So Nichols comes down and watches the second act, comes backstage, he says, “That was really good, how soon could you learn Mickey?” Mickey was the role that Ron Silver was playing that Chris Walken also played. I said, “I don’t know, maybe a couple weeks.” He goes, “Learn Mickey too.” So I learned Mickey, and then one day I’m told, “You’re going on tomorrow night as Mickey.”
Nichols comes, sees the second act, comes backstage, says, “That was really good. I mean, that was really funny, how soon could you learn Eddie?” And so I became the pinch hitter on Hurlyburly, I learned all the male parts, including Jerry Stiller’s, although I never went on as Jerry Stiller’s part. And then I left the play, and I guess about two months later I get this phone call from Mike Nichols, and he’s like, “Kevin, how are you?” And I’m like, “I’m fine, what can I do for you?” He says, “Well, I’m going to make a film this summer with Mandy and Meryl, and there’s a role I’d like you to come in and audition for.” So I went in, auditioned, he cast me as this mugger on a subway. Then there’s this whole upheaval that happens because he then doesn’t continue with Mandy Patinkin, Mandy leaves the movie, and he asked Jack Nicholson to come in and replace Mandy Patinkin.
So now I had no scenes with him, but I’m in a movie with Jack Nicholson and Meryl Streep, and my first scene in this movie, which I shot on my birthday, July 26th of 85′, I got to Wink at Meryl Streep in this scene. And I was so nervous I literally couldn’t wink, Nichols had to calm me down and help me wink. But that became my very first film. And he was incredible, and he let me come and watch when they were shooting scenes I wasn’t in. And I remember ending up one day in the makeup trailer, on the same day we were working, Jack and Me, we had no scene together. But I remember him coming in, and they put him down in the chair, and they put frozen cucumbers on his eyes, and did his neck, and then they raised him up and did his face. And then I remember Nicholson went like this, looked in the mirror, and he went, “Another day, another $50,000.” And walked out of the trailer.

And I saw Chris Walken come onto the balcony, and I was like, “Oh, shit, it’s Christopher Walken.” And he walked up to… And he went, “Kevin, I saw your little sketch, it was funny, ha ha.”

And he’s always Christopher Waken, but somehow works for all these different characters. So I guess we were talking about House of Cards two hours ago before we took a tangent upon a tangent. But there’s a moment in episode one where President Walker broke his promise to Frank Underwood that he would make him the Secretary of State. Was this when the monster in Frank was born or was the monster always there? For you looking at that character, was there an idealistic notion to him that there’s loyalty and that broke him? Or did he always know that this whole world is about manipulation, and do anything to get power?

Was this when the monster in Frank was born or was the monster always there? For you looking at that character, was there an idealistic notion to him that there’s loyalty and that broke him? Or did he always know that this whole world is about manipulation, and do anything to get power?
Kevin Spacey
Well, it might have been the first moment an audience saw him be betrayed, but it certainly was not the betrayal he’d experienced. And once you start to get to know him, and learn about his life, and learn about his father, and learn about his friends, and learn about their relationship, and learn what he was like even as a cadet, I think you start to realize that this is a man who has very strong beliefs about loyalty. And so it wasn’t the first, it was just the first moment that in terms of the storyline that’s being built. Knight Takes King was the name of our production company.

Yeah. What do you think motivated him at that moment and throughout the show? Was it all about power and also legacy, or was there some small part underneath it all where he wanted to actually do good in the world?

No, I think power is a afterthought, what he loved more than anything was being able to predict how human beings would react, he was a behavioral psychologist. And he was 17 moves ahead in the chess game, he could know if he did this at this moment, that eventually this would happen, he was able to be predictive and was usually right. He knew just how far he needed to push someone to get them to do what he needed them to do in order to make the next step work.

Kevin Spacey
Well, you call them evil. But the reason I say that, and I don’t mean to be snarky about it, but the reason I say it that way is because I never judge the people I play. And the people that I have played or that any actor has played don’t necessarily view themselves as this label, it’s easy to say, but that’s not the way I can think. I cannot judge a character I play and then play them well, I have to be free of judgment, I have to just play them and let the cards drop where they may and let an audience judge. I mean, the fact that you use that word is perfectly fine, that’s your… But it’s like people asking me, “Was I really from K-PAX or not?” It just entirely depends on your perspective.

Do roles like that, like Seven, like Frank Underwood, like Lester from American Beauty, do they change you psychologically as a person? So walking around in the skin of these characters, these complex characters with very different moral systems.

I absolutely believe that wandering around in someone else’s ideas, in someone else’s clothes, in someone else’s shoes teaches you enormous empathy. And that goes to the heart of not judging. And I have found that I have been so moved by… I mean, look, yes, you’ve identified the darker characters, but I played Clarence Darrow three times, I’ve played a play called National Anthems, I’ve done movies like Recount. I’ve done films like The Ref, I’ve done films that in which that doesn’t exist in any of those characters, those qualities.

But I have to put them on an equal footing and say, “I have to just play them as best I can.” And not decide to wield judgment over them.

In Gulag Archipelago, Aleksandr Solzhenitsyn famously writes about the line between good and evil, and that it runs to the heart of every man. So the full paragraph there when he talks about the line, “During the life of any heart this line keeps changing place, sometimes it is squeezed one way by exuberant evil, and sometimes it shifts to allow enough space for good to flourish. One and the same human being is, at various ages, under various circumstances, a totally different human being. At times, he is close to being a devil, at times to sainthood. But his name doesn’t change, and to that name we ascribe the whole lot, good and evil.” What do you think about this note, that we’re all capable of good and evil, and throughout life that line moves and shifts throughout the day, throughout every hour?

Yeah. I mean, one of the things that I’ve been focused on very succinctly is the idea that every day is an opportunity. It’s an opportunity to make better decisions, to learn and to grow. And I also think that… Look, I grew up not knowing if my parents loved me, particularly my father. I never had a sense that I was loved, and that stayed with me my whole life. And when I think back at who my father was, and more succinctly who he became, it was a gradual, and slow, and sad development. When I’ve gone back, and now I’ve looked at diaries my father kept and albums he kept, particularly when he was a medic in the US Army, served our country with distinction. When the war was over and they went to Germany, the things my father said, the things that he wrote, the things that he believed were as patriotic as any American soldier who had ever served. But then when he came back to America and he had a dream of being a journalist, or his big hope was that he was going to be the great American novelist, he wanted to be a creative novelist, and so he sat in his office and he wrote for 45 years and never published anything. And somewhere along the way, in order to make money, he became what they call a technical procedure writer. Which the best way to describe that is that if you built the F-16 aircraft, my father would have written the manual to tell you how to do it. I mean, as boring, as technical, as tedious as you can imagine.

Which the best way to describe that is that if you built the F-16 aircraft, my father would have written the manual to tell you how to do it. I mean, as boring, as technical, as tedious as you can imagine.
And so somewhere in the sixties and into the seventies, my father fell in with groups of people and individuals, pretend intellectuals, who started to give him reasons why he was not successful as a white Aryan man in the United States. And over time, my father became a white supremacist. And I cannot tell you the amount of times as a young boy that my father would sit me down and lecture me for hours, and hours, and hours about his fucked up ideas of America, of prejudice, of white supremacy. And thank God for my sister who said, “Don’t listen to a thing he says, he’s out of his mind.” And even though I was young, I knew everything he was saying was against people, and I loved people. I had so many wonderful friends, my best friend Mike, who’s still my close friend to this day, I was afraid to bring him to my house because I was afraid that my father would find out he was Jewish, or that my father would leave his office door open and someone would see his Nazi flag, or his pictures of Hitler, or Nazi books, or what he might say. So when I found theater in the eighth grade, and debate club, and choir, and festivals, and plays, and everything I could do to participate in that wouldn’t make me to come back home, I did.
And I’ve reconcile who he became, because the gap between that man who was in the US Army as a medic and the man he became, I could never fill that gap. But I’ve forgiven him. But then at the same time I’ve to look at my mother and say, “She made excuses for him.” “Oh, he just needs to get it off his chest. Oh, it doesn’t matter, just let him say.” So while on the outside, I would say, “Oh, yeah, my mother loved me, but she didn’t protect me.” So was all the stuff that she expressed, and all of the attention, and all the love that I felt, was that because I became successful and I was able to fulfill an emptiness that she’d lived with her whole life with him? I don’t know, but I’ve had to ask myself those questions over these last years to try to reconcile that for myself.

I don’t have any memory of that. I was in a program, and they were showing us an experiment that they’d done with psychologists, and mothers and fathers and their children, and the children were anywhere between six months and a year sitting in a little crib. And the exercise was this, parents are playing with the baby right there, toys, yada ya, baby’s laughing. And then the psychologist would say, “Stop.” And the parent would go like this. And you would then watch for the next two and a half, three minutes this child trying to get their parents’ attention in any possible way. And I remember when I was sitting in this theater watching this, I saw myself, that was me screaming, and reaching out, and trying to get my parents’ attention. That was me, and that was not something I’d ever remembered before, but I knew what that baby was going through.

I mean, that guy who finally got out of prison, he was wrongly accused, that guy who served his time and got out of prison. We see so many people saying, “Let’s find a path for that person, let’s help that person rejoin society.” But there is an odd situation if you’re in the entertainment industry, you’re not offered that kind of a path. And I hope that the fear that people are experiencing will eventually subside and common sense will get back to the table.

I’m personally excited for the future and believe it will be a good one in part because of the amazing technological innovation we humans create, but we must absolutely not do so with blinders on ignoring the possible risks, including existential risks of those technologies. That’s what this conversation is about. This is the Lex Fridman podcast. To support it, please check out our sponsors in the description. Now dear friends, here’s Roman Yampolskiy.
What to you is the probability that super intelligent AI will destroy all human civilization?
So my solution was, okay, we don’t have to compromise on room temperature. You have your universe, I have mine, whatever you want, and if you like me, you can invite me to visit your universe. We don’t have to be independent, but the point is you can be, and virtual reality is getting pretty good. It’s going to hit a point where you can’t tell the difference, and if you can’t tell if it’s real or not, what’s the difference?
Let me ask about Yann LeCun. He’s somebody who you’ve had a few exchanges with and he’s somebody who actively pushes back against this view that AI is going to lead to destruction of human civilization, also known as AI doomerism. So in one example that he tweeted, he said, “I do acknowledge risks, but,” two points, “One, open research and open source are the best ways to understand and mitigate the risks. Two, AI is not something that just happens. We build it. We have agency in what it becomes. Hence, we control the risks. We meaning humans. It’s not some sort of natural phenomena that we have no control over.” Can you make the case that he’s right and can you try to make the case that he’s wrong?
Even in the autonomous weapon systems, there’s not been mass deployments of autonomous weapon systems, luckily. The automation in war currently is very limited, that the automation is at the scale of individuals versus at the scale of strategy and planning. I think one of the challenges here is where is the dangers and the intuition the [inaudible 00:54:40] and others have is, let’s keep in the open building AI systems until the dangers start rearing their heads and they become more explicit, they start being case studies, illustrative case studies that show exactly how the damage by AD systems is done, then regulation can step in. Then brilliant engineers can step up, and we can have Manhattan style projects that defend against such systems. That’s kind of the notion. And I guess, a tension with that is the idea that for you, we need to be thinking about that now, so that we’re ready, because we’ll have not much time once the systems are deployed. Is that true?
But a lot of the conversation I’m having with you now is also kind of wondering almost at a technical level, how can AI escape control? What would that system look like? Because it, to me, is terrifying and fascinating. And also fascinating to me is maybe the optimistic notion it’s possible to engineer systems that defend against that. One of the things you write a lot about in your book is verifiers. So, not humans. Humans are also verifiers. But software systems that look at AI systems, and help you understand, “This thing is getting real weird.” Help you analyze those systems. So maybe this is a good time to talk about verification. What is this beautiful notion of verification?
So, verifiers are not perfect. Usually, they are either a single human or communities of humans and it’s basically kind of like a democratic vote. Community of mathematicians agrees that this proof is correct, mostly correct. Even today, we’re starting to see some mathematical proofs as so complex, so large that mathematical community is unable to make a decision. It looks interesting, it looks promising, but they don’t know. They will need years for top scholars to study to figure it out. So of course, we can use AI to help us with this process, but AI is a piece of software which needs to be verified.
If aliens give us well-aligned super intelligence, we can use that to create our own safe AI. But it’s a catch-22. You need to have already proven to be safe system to verify this new system of equal or greater complexity.
If a system makes a billion decisions a second, and you use it for a hundred years, you’re still going to deal with a problem. This is wonderful research. I’m so happy they’re doing it. This is great, but it is not going to be a permanent solution to that problem.
And once you take that leap, that’s when a lot of the challenges seems to happen because the kind of bugs you can find now seems more akin to the current normal software debugging kind of process. But whenever you can do self-replication and arbitrary self-improvement, that’s when a bug can become a real problem, real fast. So, what is the difference to you between verification of a non-self-improving system versus a verification of a self-improving system?
So, it’s hard to be completely optimistic about our results here. I can name 10 excellent breakthrough papers in machine learning. I would struggle to name equally important breakthroughs in safety. A lot of times a safety paper will propose a toy solution and point out 10 new problems discovered as a result. It’s like this fractal. You’re zooming in and you see more problems and it’s infinite in all directions.
We talk about guardrails for AI. Well, that’s a fence. I can dig a tunnel under it, I can jump over it, I can climb it, I can walk around it. You may have a very nice guardrail, but in a real world it’s not a permanent guarantee of safety. And again, this is a fundamental difference. We are not saying we need to be 90% safe to get those trillions of dollars of benefit. We need to be a hundred percent indefinitely or we might lose the principle.
So, basically there is a paper we published in ACM surveys, which looks at about 50 different impossibility results, which may or may not be relevant to this problem, but we don’t have enough human resources to investigate all of them for relevance to AI safety. The ones I mentioned to you, I definitely think would be handy, and that’s what we see AI safety researchers working on. Explainability is a huge one.
The problem is that it’s very hard to separate capabilities work from safety work. If you make good progress in explainability, now the system itself can engage in self-improvement much easier, increasing capability greatly. So, it’s not obvious that there is any research which is pure safety work without disproportionate increasing capability and danger.
I think super alignment is not quite the same as the kind of thing I’m referring to with engineers are worried about. Super alignment is saying, “For future systems that we don’t quite yet have, how do we keep them safe?” You are trying to be a step ahead. It’s a different kind of problem because it is almost more philosophical. It’s a really tricky one because you’re trying to prevent future systems from escaping control of humans. I don’t think there’s been… Man, is there anything akin to it in the history of humanity? I don’t think so, right?
Don’t you think all those engineers are constantly worrying about this, thinking about this? Which is a little bit different than the super alignment team that’s thinking a little bit farther into the future.
That’s the best they can do for mundane software, word processor, tax software. No liability, no responsibility. Just as long as you agree not to sue us, you can use it. If this is a state of the art in systems which are narrow accountants, stable manipulators, why do we think we can do so much better with much more complex systems across multiple domains in the environment with malevolent actors? With again, self-improvement with capabilities exceeding those of humans thinking about it.
So, it’s definitely a change. It’s difficult to keep up. I used to be able to read every paper on AI safety. Then I was able to read the best ones. Then the titles, and now I don’t even know what’s going on. By the time this interview is over, they probably had GPT-VI released, and I have to deal with that when I get back home.
What I like about Wolfram’s work is that he talks about irreducibility. You have to run the simulation. You cannot predict what it’s going to do ahead of time. And I think that’s very relevant to what we’re talking about with those very complex systems. Until you live through it, you cannot ahead of time tell me exactly what it’s going to do.
Thanks for listening to this conversation with Roman Yampolskiy. To support this podcast, please check out our sponsors in the description. And now let me leave you with some words from Frank Herbert in Dune. “I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face fear. I will permit it to pass over me and through me. And when it has gone past, I will turn the inner eye to see its path. Where the fear has gone, there will be nothing. Only I will remain.”hank you for listening and hope to see you next time.

If we create general superintelligences, I don’t see a good outcome long-term for humanity. So there is X-risk, existential risk, everyone’s dead. There is S-risk, suffering risks, where everyone wishes they were dead. We have also idea for I-risk, ikigai risks, where we lost our meaning. The systems can be more creative. They can do all the jobs. It’s not obvious what you have to contribute to a world where superintelligence exists. Of course, you can have all the variants you mentioned, where we are safe, we are kept alive, but we are not in control. We are not deciding anything. We’re like animals in a zoo. There is, again, possibilities we can come up with as very smart humans and then possibilities something a thousand times smarter can come up with for reasons we cannot comprehend.

The following is a conversation with Roman Yampolskiy, an AI safety and security researcher and author of a new book titled AI: Unexplainable, Unpredictable, Uncontrollable. He argues that there’s almost 100% chance that AGI will eventually destroy human civilization. As an aside, let me say that I’ll have many often technical conversations on the topic of AI, often with engineers building the state-of-the-art AI systems. I would say those folks put the infamous P(doom) or the probability of AGI killing all humans at around one to 20%, but it’s also important to talk to folks who put that value at 70, 80, 90, and is in the case of Roman, at 99.99 and many more nines percent.

I’m personally excited for the future and believe it will be a good one in part because of the amazing technological innovation we humans create, but we must absolutely not do so with blinders on ignoring the possible risks, including existential risks of those technologies. That’s what this conversation is about. This is the Lex Fridman podcast. To support it, please check out our sponsors in the description. Now dear friends, here’s Roman Yampolskiy.
Existential risk of AGI
What to you is the probability that super intelligent AI will destroy all human civilization?
Roman Yampolskiy
What’s the timeframe?

Let’s say a hundred years, in the next hundred years.

So the problem of controlling AGI or superintelligence in my opinion, is like a problem of creating a perpetual safety machine. By analogy with perpetual motion machine, it’s impossible. Yeah, we may succeed and do good job with GPT-5, six, seven, but they just keep improving, learning, eventually self-modifying, interacting with the environment, interacting with malevolent actors. The difference between cybersecurity, narrow AI safety and safety for general AI for superintelligence, is that we don’t get a second chance. With cybersecurity, somebody hacks your account, what’s the big deal? You get a new password, new credit card, you move on. Here, if we’re talking about existential risks, you only get one chance. So you are really asking me what are the chances that we’ll create the most complex software ever on the first try with zero bugs and it’ll continue to have zero bugs for a hundred years or more.

So there is an incremental improvement of systems leading up to AGI. To you, it doesn’t matter if we can keep those safe. There’s going to be one level of system at which you cannot possibly control it.

Roman Yampolskiy
I don’t think we so far have made any system safe at the level of capability they display. They already have made mistakes. We had accidents. They’ve been jail broken. I don’t think there is a single large language model today, which no one was successful at making do something developers didn’t intend it to do.

Lex Fridman
There’s a difference between getting it to do something unintended, getting it to do something that’s painful, costly, destructive, and something that’s destructive to the level of hurting billions of people or hundreds of millions of people, billions of people, or the entirety of human civilization. That’s a big leap.

Roman Yampolskiy
Exactly, but the systems we have today have capability of causing X amount of damage. So when we fail, that’s all we get. If we develop systems capable of impacting all of humanity, all of universe, the damage is proportionate.

What to you are the possible ways that such mass murder of humans can happen?

Roman Yampolskiy
It’s always a wonderful question. So one of the chapters in my new book is about unpredictability. I argue that we cannot predict what a smarter system will do. So you’re really not asking me how superintelligence will kill everyone. You’re asking me how I would do it. I think it’s not that interesting. I can tell you about the standard nanotech, synthetic, bio, nuclear. Superintelligence will come up with something completely new, completely super. We may not even recognize that as a possible path to achieve that goal.

So there is an unlimited level of creativity in terms of how humans could be killed, but we could still investigate possible ways of doing it. Not how to do it, but at the end, what is the methodology that does it. Shutting off the power and then humans start killing each other maybe, because the resources are really constrained. Then there’s the actual use of weapons like nuclear weapons or developing artificial pathogens, viruses, that kind of stuff. We could still think through that and defend against it. There’s a ceiling to the creativity of mass murder of humans here. The options are limited.

Roman Yampolskiy
They’re limited by how imaginative we are. If you are that much smarter, that much more creative, you’re capable of thinking across multiple domains, do novel research in physics and biology, you may not be limited by those tools. If squirrels were planning to kill humans, they would have a set of possible ways of doing it, but they would never consider things we can come up.

So are you thinking about mass murder and destruction of human civilization or are you thinking of with squirrels, you put them in a zoo and they don’t really know they’re in a zoo? If we just look at the entire set of undesirable trajectories, majority of them are not going to be death. Most of them are going to be just things like brave new world where the squirrels are fed dopamine and they’re all doing some fun activity and the fire, the soul of humanity is lost because of the drug that’s fed to it, or literally in a zoo. We’re in a zoo, we’re doing our thing, we’re playing a game of Sims, and the actual players playing that game are AI systems. Those are all undesirable because the free will. The fire of human consciousness is dimmed through that process, but it’s not killing humans. So are you thinking about that or is the biggest concern literally the extinctions of humans?

Roman Yampolskiy
I think about a lot of things. So that is X-risk, existential risk, everyone’s dead. There is S-risk, suffering risks, where everyone wishes they were dead. We have also idea for I-risk, ikigai risks, where we lost our meaning. The systems can be more creative. They can do all the jobs. It’s not obvious what you have to contribute to a world where superintelligence exists.

Ikigai risk
Lex Fridman
I would love to dig into each of those X-risk, S-risk, and I-risk. So can you linger on I-risk? What is that?

Roman Yampolskiy
So Japanese concept of ikigai, you find something which allows you to make money. You are good at it and the society says we need it. So you have this awesome job. You are podcaster gives you a lot of meaning. You have a good life. I assume you’re happy. That’s what we want more people to find, to have. For many intellectuals, it is their occupation, which gives them a lot of meaning. I’m a researcher, philosopher, scholar. That means something to me In a world where an artist is not feeling appreciated, because his art is just not competitive with what is produced by machines or a writer or scientist will lose a lot of that. At the lower level, we’re talking about complete technological unemployment. We’re not losing 10% of jobs. We’re losing all jobs. What do people do with all that free time? What happens then? Everything society is built on is completely modified in one generation. It’s not a slow process where we get to figure out how to live that new lifestyle, but it’s pretty quick.

In that world, can’t humans do what humans currently do with chess, play each other, have tournaments, even though AI systems are far superior this time in chess? So we just create artificial games, or for us they’re real. Like the Olympics and we do all kinds of different competitions and have fun. Maximize the fun and let the AI focus on the productivity.

Roman Yampolskiy
It’s an option. I have a paper where I try to solve the value alignment problem for multiple agents and the solution to avoid compromise is to give everyone a personal virtual universe. You can do whatever you want in that world. You could be king. You could be slave. You decide what happens. So it’s basically a glorified video game where you get to enjoy yourself and someone else takes care of your needs and the substrate alignment is the only thing we need to solve. We don’t have to get 8 billion humans to agree on anything.

Okay. So why is that not a likely outcome? Why can’t the AI systems create video games for us to lose ourselves in each with an individual video game universe?

We’re playing that video game and now we’re creating what… Maybe we’re creating artificial threats for ourselves to be scared about, because fear is really exciting. It allows us to play the video game more vigorously.

Some people choose to play on a more difficult level with more constraints. Some say, okay, I’m just going to enjoy the game high privilege level. Absolutely.

Personal universes.

Lex Fridman
So that’s one of the possible outcomes, but what in general is the idea of the paper? So it’s looking at multiple agents. They’re human AI, like a hybrid system, whether it’s humans and AIs or is it looking at humans or just intelligent agents?

Roman Yampolskiy
In order to solve value alignment problem, I’m trying to formalize it a little better. Usually we’re talking about getting AIs to do what we want, which is not well-defined are we’re talking about creator of a system, owner of that AI, humanity as a whole, but we don’t agree on much. There is no universally accepted ethics, morals across cultures, religions. People have individually very different preferences politically and such. So even if we somehow managed all the other aspects of it, programming those fuzzy concepts in, getting AI to follow them closely, we don’t agree on what to program in.

So my solution was, okay, we don’t have to compromise on room temperature. You have your universe, I have mine, whatever you want, and if you like me, you can invite me to visit your universe. We don’t have to be independent, but the point is you can be, and virtual reality is getting pretty good. It’s going to hit a point where you can’t tell the difference, and if you can’t tell if it’s real or not, what’s the difference?
Lex Fridman
So basically give up on value alignment, create the multiverse theory. This is create an entire universe for you with your values.

You still have to align with that individual. They have to be happy in that simulation, but it’s a much easier problem to align with one agent versus 8 billion agents plus animals, aliens.

Lex Fridman
Okay. So okay, that’s giving up on the value alignment problem. Well, is there any way to solve the value alignment problem where there’s a bunch of humans, multiple humans, tens of humans or 8 billion humans that have very different set of values?

It seems contradictory. I haven’t seen anyone explain what it means outside of words, which pack a lot, make it good, make it desirable, make it something they don’t regret. How do you specifically formalize those notions? How do you program them in? I haven’t seen anyone make progress on that so far.

Isn’t that the whole optimization journey that we’re doing as a human civilization? We’re looking at geopolitics. Nations are in a state of anarchy with each other. They start wars, there’s conflict, and oftentimes they have a very different views of what is good and what is evil. Isn’t that what we’re trying to figure out, just together trying to converge towards that? So we’re essentially trying to solve the value alignment problem with humans

Fight, but the examples you gave, some of them are, for example, two different religions saying this is our holy site and we are not willing to compromise it in any way. If you can make two holy sites in virtual worlds, you solve the problem, but if you only have one, it’s not divisible. You’re stuck there.

What if we want to be at tension with each other, and through that tension, we understand ourselves and we understand the world. So that’s the intellectual journey we’re on as a human civilization, is we create intellectual and physical conflict and through that figure stuff out.

If we go back to that idea of simulation, and this is entertainment giving meaning to us, the question is how much suffering is reasonable for a video game? So yeah, I don’t mind a video game where I get haptic feedback. There is a little bit of shaking. Maybe I’m a little scared. I don’t want a game where kids are tortured literally. That seems unethical, at least by our human standards.

Are you suggesting it’s possible to remove suffering if we’re looking at human civilization as an optimization problem?

Roman Yampolskiy
So we know there are some humans who, because of a mutation, don’t experience physical pain. So at least physical pain can be mutated out, re-engineered out. Suffering in terms of meaning, like you burn the only copy of my book, is a little harder. Even there, you can manipulate your hedonic set point, you can change defaults, you can reset. Problem with that is if you start messing with your reward channel, you start wireheading and end up blissing out a little too much.

Well, that’s the question. Would you really want to live in a world where there’s no suffering as a dark question? Is there some level of suffering that reminds us of what this is all for?

Roman Yampolskiy
I think we need that, but I would change the overall range. So right now it’s negative infinity to positive infinity pain-pleasure axis. I would make it like zero to positive infinity and being unhappy is like I’m close to zero.

Suffering risk

Okay, so what’s S-risk? What are the possible things that you’re imagining with S-risk? So mass suffering of humans, what are we talking about there caused by AGI?

So there are many malevolent actors. We can talk about psychopaths, crazies, hackers, doomsday cults. We know from history they tried killing everyone. They tried on purpose to cause maximum amount of damage, terrorism. What if someone malevolent wants on-purpose to torture all humans as long as possible? You solve aging. So now you have functional immortality and you just try to be as creative as you can.

Do you think there is actually people in human history that try to literally maximize human suffering? In just studying people who have done evil in the world, it seems that they think that they’re doing good and it doesn’t seem like they’re trying to maximize suffering. They just cause a lot of suffering as a side effect of doing what they think is good.

So there are different malevolent agents. Some may be just gaining personal benefit and sacrificing others to that cause. Others we know for effect trying to kill as many people as possible. When we look at recent school shootings, if they had more capable weapons, they would take out not dozens, but thousands, millions, billions.

Lex Fridman
Well, we don’t know that, but that is a terrifying possibility and we don’t want to find out. If terrorists had access to nuclear weapons, how far would they go? Is there a limit to what they’re willing to do? Your sense is there is some malevolent actors where there’s no limit?

There is mental diseases where people don’t have empathy, don’t have this human quality of understanding suffering in others.

Again, I would like to assume that normal people never think like that. There’s always some sort of psychopaths, but yeah.

To you, AGI systems can carry that and be more competent at executing that.

They can certainly be more creative. They can understand human biology better understand, understand our molecular structure, genome. Again, a lot of times torture ends, then individual dies. That limit can be removed as well.

So if we’re actually looking at X-Risk and S-Risk, as the systems get more and more intelligent, don’t you think it is possible to anticipate the ways they can do it and defend against it like we do with the cybersecurity will do security systems?

Right. We can definitely keep up for a while. I’m saying you cannot do it indefinitely. At some point, the cognitive gap is too big. The surface you have to defend is infinite, but attackers only need to find one exploit.

Timeline to AGI

I don’t know for sure. The prediction markets right now are saying 2026 for AGI. I heard the same thing from CEO of Anthropic DeepMind. So maybe we’re two years away, which seems very soon given we don’t have a working safety mechanism in place or even a prototype for one. There are people trying to accelerate those timelines, because they feel we’re not getting there quick enough.

So the definitions we used to have, and people are modifying them a little bit lately, artificial general intelligence was a system capable of performing in any domain a human could perform. So you’re creating this average artificial person. They can do cognitive labor, physical labor where you can get another human to do it. Superintelligence was defined as a system which is superior to all humans in all domains. Now people are starting to refer to AGI as if it’s superintelligence. I made a post recently where I argued, for me at least, if you average out over all the common human tasks, those systems are already smarter than an average human. So under that definition we have it. Shane Legg has this definition of where you’re trying to win in all domains. That’s what intelligence is. Now, are they smarter than elite individuals in certain domains? Of course not. They’re not there yet, but the progress is exponential.

See, I’m much more concerned about social engineering. So to me, AI’s ability to do something in the physical world, like the lowest hanging fruit, the easiest set of methods, is by just getting humans to do it. It’s going to be much harder to be the viruses to take over the minds of robots where the robots are executing the commands. It just seems like social engineering of humans is much more likely.

Human level is general in the domain of expertise of humans. We know how to do human things. I don’t speak dog language. I should be able to pick it up if I’m a general intelligence. It’s an inferior animal. I should be able to learn that skill, but I can’t. A general intelligence, truly universal general intelligence, should be able to do things like that humans cannot do.

AGI turing test

I’m old-fashioned. I like Turing tests. I have a paper where I equate passing Turing tests to solving AI complete problems because you can encode any questions about any domain into the Turing test. You don’t have to talk about how was your day. You can ask anything. So the system has to be as smart as a human to pass it in a true sense.

You can develop a test which will give you positives. If it lies to you or has those ideas, you cannot develop a test which rules them out. There is always possibility of what Bostrom calls a treacherous turn, where later on a system decides for game theoretic reasons, economic reasons to change its behavior, and we see the same with humans. It’s not unique to AI. For millennia, we try developing morals, ethics, religions, lie detector tests, and then employees betray the employers, spouses betray family. It’s a pretty standard thing intelligent agents sometimes do.

If you know the truth and it tells you something false, you can detect that, but you cannot know in general every single time. Again, the system you’re testing today may not be lying. The system you’re testing today may know you are testing it, and so behaving. Later on, after it interacts with the environment, interacts with other systems, malevolent agents learns more, it may start doing those things.

If they realize, okay, this human will be very happy if I tell them the following, they will do it if it brings them more points. They don’t have to keep track of it. It’s just the right answer to this problem every single time.

Some people think that they will be able to detect problem behaviors and correct them at the time when we get there. I don’t think it’s a good idea. I am strongly against it, but yeah, there are quite a few people who in general are so optimistic about this technology, it could do no wrong. They want it developed as soon as possible, as capable as possible.

Yann LeCun and open source AI
Let me ask about Yann LeCun. He’s somebody who you’ve had a few exchanges with and he’s somebody who actively pushes back against this view that AI is going to lead to destruction of human civilization, also known as AI doomerism. So in one example that he tweeted, he said, “I do acknowledge risks, but,” two points, “One, open research and open source are the best ways to understand and mitigate the risks. Two, AI is not something that just happens. We build it. We have agency in what it becomes. Hence, we control the risks. We meaning humans. It’s not some sort of natural phenomena that we have no control over.” Can you make the case that he’s right and can you try to make the case that he’s wrong?
Roman Yampolskiy
I cannot make a case that he’s right. He is wrong in so many ways it’s difficult for me to remember all of them. He’s a Facebook buddy, so I have a lot of fun having those little debates with him. So I’m trying to remember their arguments. So one, he says, we are not gifted this intelligence from aliens. We are designing it. We are making decisions about it. That’s not true. It was true when we had expert systems, symbolic AI decision trees. Today, you set up parameters for a model and you water this plant. You give it data, you give it compute, and it grows. After it’s finished growing into this alien plant, you start testing it to find out what capabilities it has. It takes years to figure out, even for existing models. If it’s trained for six months, it’ll take you two, three years to figure out basic capabilities of that system. We still discover new capabilities in systems which are already out there. So that’s not the case.

For Yann LeCun, I think there’s a ceiling that happens that we have full control over. Even if we don’t understand the internals of the emergence, how the emergence happens, there’s a sense that we have control and an understanding of the approximate ceiling of capability, the limits of the capability.

Now you’re giving open source weapons to psychopaths. Do we want to open source nuclear weapons, biological weapons? It’s not safe to give technology so powerful to those who may misalign it, even if you are successful at somehow getting it to work in the first place in a friendly manner.

So nuclear weapons, there’s no nuclear weapon and then there’s a nuclear weapon. With AI systems, there’s a gradual improvement of capability and you get to perform that improvement incrementally, and so open source allows you to study how things go wrong. I study the very process of emergence, study AI safety and those systems when there’s not high level of danger, all that kind of stuff.

I don’t think it always works with the precedent. You’re not stuck doing it the way you always did. It sets a precedent of open research and open development such that we get to learn together and then the first time there’s a sign of danger, some dramatic thing happened, not a thing that destroys human civilization, but some dramatic demonstration of capability that can legitimately lead to a lot of damage, then everybody wakes up and says, “Okay, we need to regulate this. We need to come up with safety mechanism that stops this.” But at this time, maybe you can educate me, but I haven’t seen any illustration of significant damage done by intelligent AI systems.

So I have a paper which collects accidents through history of AI and they always are proportionate to capabilities of that system. So if you have Tic-Tac-Toe playing AI, it will fail to properly play and loses the game, which it should draw trivial. Your spell checker will misspell word, so on. I stopped collecting those because there are just too many examples of AI’s failing at what they are capable of. We haven’t had terrible accidents in a sense of billion people got killed. Absolutely true. But in another paper I argue that those accidents do not actually prevent people from continuing with research and actually they kind of serve like vaccines. A vaccine makes your body a little bit sick so you can handle the big disease later, much better. It’s the same here. People will point out, “You know that AI accident we had where 12 people died,” everyone’s still here, 12 people is less than smoking kills. It’s not a big deal. So we continue. So in a way it will actually be confirming that it’s not that bad.

It matters how the deaths happen, whether it’s literally murdered by the AI system, then one is a problem, but if it’s accidents because of increased reliance on automation for example, so when airplanes are flying in an automated way, maybe the number of plane crashes increased by 17% or something, and then you’re like, “Okay, do we really want to rely on automation?” I think in a case of automation airplanes, it decreased significantly. Okay, same thing with autonomous vehicles. Okay, what are the pros and cons? What are the trade-offs here? And you can have that discussion in an honest way, but I think the kind of things we’re talking about here is mass scale pain and suffering caused by AI systems, and I think we need to see illustrations of that in a very small scale to start to understand that this is really damaging. Versus Clippy. Versus a tool that’s really useful to a lot of people to do learning to do summarization of text, to do question-answer, all that kind of stuff to generate videos. A tool. Fundamentally a tool versus an agent that can do a huge amount of damage.

Lex Fridman
There’d been fear-mongering about cars for a long time. The transition from horses to cars, there’s a really nice channel that I recommend people check out, Pessimist Archive that documents all the fear-mongering about technology that’s happened throughout history. There’s definitely been a lot of fear-mongering about cars. There’s a transition period there about cars, about how deadly they are. We can try. It took a very long time for cars to proliferate to the degree they have now. And then you could ask serious questions in terms of the miles traveled, the benefit to the economy, the benefit to the quality of life that cars do, versus the number of deaths; 30, 40,000 in the United States. Are we willing to pay that price? I think most people when they’re rationally thinking, policymakers will say, “Yes.” We want to decrease it from 40,000 to zero and do everything we can to decrease it. There’s all kinds of policies, incentives you can create to decrease the risks with the deployment of technology. But then you have to weigh the benefits and the risks of the technology and the same thing would be done with AI.
There’d been fear-mongering about cars for a long time. The transition from horses to cars, there’s a really nice channel that I recommend people check out, Pessimist Archive that documents all the fear-mongering about technology that’s happened throughout history. There’s definitely been a lot of fear-mongering about cars. There’s a transition period there about cars, about how deadly they are. We can try. It took a very long time for cars to proliferate to the degree they have now. And then you could ask serious questions in terms of the miles traveled, the benefit to the economy, the benefit to the quality of life that cars do, versus the number of deaths; 30, 40,000 in the United States. Are we willing to pay that price? I think most people when they’re rationally thinking, policymakers will say, “Yes.” We want to decrease it from 40,000 to zero and do everything we can to decrease it. There’s all kinds of policies, incentives you can create to decrease the risks with the deployment of technology. But then you have to weigh the benefits and the risks of the technology and the same thing would be done with AI.

You need data, you need to know. But if I’m right and it’s unpredictable, unexplainable, uncontrollable, you cannot make this decision. We’re gaining $10 trillion of wealth, but we’re we don’t know how many people. You basically have to perform an experiment on 8 billion humans without their consent. And even if they want to give you consent, they can’t because they cannot give informed consent. They don’t understand those things.

Right. That happens when you go from the predictable to the unpredictable very quickly. But it’s not obvious to me that AI systems would gain capabilities so quickly that you won’t be able to collect enough data to study the benefits and risks.

We’re literally doing it. The previous model we learned about after we finished training it, what it was capable of. Let’s say we stopped GPT-4 training run around human capability, hypothetically. We start training GPT- 5 and I have no knowledge of insider training runs or anything and started that point of about human and we train it for the next nine months. Maybe two months in, it becomes super intelligent. We continue training it. At the time when we start testing it, it is already a dangerous system. How dangerous? I have no idea, but never people training it.

At the training stage, but then there’s a testing stage inside the company, they can start getting intuition about what the system is capable to do. You’re saying that somehow from leap from GPT-4 to GPT-5 can happen, the kind of leap where GPT-4 was controllable and GPT-5 is no longer controllable and we get no insights from using GPT-4 about the fact that GPT-5 will be uncontrollable. That’s the situation you’re concerned about. Where there leap from N, to N plus one will be such that an uncontrollable system is created without any ability for us to anticipate that.

If we had capability of ahead of the run, before the training run to register exactly what capabilities that next model will have at the end of the training run, and we accurately guessed all of them, I would say you’re right, “We can definitely go ahead with this run.” We don’t have the capability.

Lex Fridman
From GPT-4, you can build up intuitions about what GPT-5 will be capable of. It’s just incremental progress. Even if that’s a big leap in capability, it just doesn’t seem like you can take a leap from a system that’s helping you write emails to a system that’s going to destroy human civilization. It seems like it’s always going to be sufficiently incremental such that we can anticipate the possible dangers, and we’re not even talking about existential risk, but just the kind of damage you can do to civilization. It seems like we’ll be able to anticipate the kinds, not the exact, but the kinds of risks it might lead to and then rapidly develop defenses ahead of time and as the risks emerge.

We’re not talking just about capabilities specific tasks, we’re talking about general capability to learn. Maybe like a child. At the time of testing and deployment, it is still not extremely capable, but as it is exposed to more data real world, it can be trained to become much more dangerous and capable.

AI control
Lex Fridman
So let’s focus then on the control problem. At which point does the system become uncontrollable? Why is it the more likely trajectory for you that the system becomes uncontrollable?

Roman Yampolskiy
So, I think at some point it becomes capable of getting out of control. For game theoretic reasons, it may decide not to do anything right away and for a long time, just collect more resources, accumulate strategic advantage. Right away, it may be still young, weak super intelligence, give it a decade. It’s in charge of a lot more resources, it had time to make backups. So it’s not obvious to me that it will strike as soon as it can.

But can we just try to imagine this future where there’s an AI system that’s capable of escaping the control of humans, and then doesn’t and waits? What’s that look like? So one, we have to rely on that system for a lot of the infrastructure. So we’ll have to give it access not just to the internet, but to the task of managing power, government, economy, this kind of stuff. And that just feels like a gradual process given the bureaucracies of all those systems involved.

But there’s a difference between software and AI. So there’s different kinds of software. So to give a single AI system access to the control of airlines and the control of the economy, that’s not a trivial transition for humanity.

No. But if it shows it is safer, in fact when it’s in control, we get better results, people will demand that it was put in place.

It just feels like that would take a long time for either humans to trust it or for the social engineering to come into play. It’s not a thing that happens overnight. It feels like something that happens across one or two decades.

Social engineering
Lex Fridman
Maybe the social engineering. For social engineering, AI systems don’t need any hardware access. It’s all software. So they can start manipulating you through social media, so on. You have AI assistants, they’re going to help you manage a lot of your day to day and then they start doing social engineering. But for a system that’s so capable that can escape the control of humans that created it, such a system being deployed at a mass scale and trusted by people to be deployed, it feels like that would take a lot of convincing.

GPT-4. I don’t know what else it’s capable of, but there are still things we haven’t discovered, can do. They may be trivial, proportionate with capability. I don’t know it writes Chinese poetry, hypothetical, I know it does, but we haven’t tested for all possible capabilities and we are not explicitly designing them. We can only rule out bugs we find. We cannot rule out bugs and capabilities because we haven’t found them.

Is it possible for a system to have hidden capabilities that are orders of magnitude greater than its non- hidden capabilities? This is the thing I’m really struggling with. Where, on the surface, the thing we understand it can do doesn’t seem that harmful. So even if it has bugs, even if it has hidden capabilities like Chinese poetry or generating effective viruses, software viruses, the damage that can do seems like on the same order of magnitude as the capabilities that we know about. So this idea that the hidden capabilities will include being uncontrollable is something I’m struggling with because GPT-4 on the surface seems to be very controllable.

Again, we can only ask and test for things we know about. There are unknown unknowns, we cannot do it. Thinking of humans, statistics savants, right? If you talk to a person like that, you may not even realize they can multiply 20 digit numbers in their head. You have to know to ask.

Fearmongering
Lex Fridman
So as I mentioned, just to linger on the fear of the unknown, so the Pessimist Archive has just documented, let’s look at data of the past at history, there’s been a lot of fear-mongering about technology. Pessimist Archive does a really good job of documenting how crazily afraid we are of every piece of technology. We’ve been afraid, there’s a blog post where Louis Anslow who created Pessimist Archive writes about the fact that we’ve been fear-mongering about robots and automation for over 100 years. So why is AGI different than the kinds of technologies we’ve been afraid of in the past?

So two things; one with wishing from tools to agents. Tools don’t have negative or positive impact. People using tools do. So guns don’t kill, people with guns do. Agents can make their own decisions. They can be positive or negative. A pit bull can decide to harm you. It’s an agent. The fears are the same. The only difference is now we have this technology. Then they were afraid of human with robots 100 years ago, they had none. Today, every major company in the world is investing billions to create them. Not every, but you understand what I’m saying?

I have not seen evidence of it. I think a lot of it is a marketing kind of discussion about the future and it’s a mission about the kind of systems we can create in the long term future. But in the short term, the kind of systems they’re creating falls fully within the definition of narrow AI. These are tools that have increasing capabilities, but they just don’t have a sense of agency, or consciousness, or self-awareness or ability to deceive at scales that would be required to do mass scale suffering and murder of humans.

Well, that’s a human question, whether humans are capable of that. Probably, some humans are capable of that. My more direct question, if it’s possible to create such a system, have a system that has that level of agency. I don’t think that’s an easy technical challenge. It doesn’t feel like we’re close to that. A system that has the kind of agency where it can make its own decisions and deceive everybody about them. The current architecture we have in machine learning and how we train the systems, how to deploy the systems and all that, it just doesn’t seem to support that kind of agency.

I really hope you are right. I think the scaling hypothesis is correct. We haven’t seen diminishing returns. It used to be we asked how long before AGI, now we should ask how much until AGI, it’s $1 trillion today it’s $1 billion next year, it’s $1 million in a few years.

But if it takes decades, then the development of tools for AI safety then becomes more and more realistic. So I guess the question is, I have a fundamental belief that humans when faced with danger, can come up with ways to defend against that danger. And one of the big problems facing AI safety currently, for me, is that there’s not clear illustrations of what that danger looks like. There’s no illustrations of AI systems doing a lot of damage, and so it’s unclear what you’re defending against. Because currently it’s a philosophical notions that, yes, it’s possible to imagine AI systems that take control of everything and then destroy all humans. It’s also a more formal mathematical notion that you talk about that it’s impossible to have a perfectly secure system. You can’t prove that a program of sufficient complexity is completely safe, and perfect and know everything about it, yes, but when you actually just pragmatically look how much damage have the AI systems done and what kind of damage, there’s not been illustrations of that.

Even in the autonomous weapon systems, there’s not been mass deployments of autonomous weapon systems, luckily. The automation in war currently is very limited, that the automation is at the scale of individuals versus at the scale of strategy and planning. I think one of the challenges here is where is the dangers and the intuition the [inaudible 00:54:40] and others have is, let’s keep in the open building AI systems until the dangers start rearing their heads and they become more explicit, they start being case studies, illustrative case studies that show exactly how the damage by AD systems is done, then regulation can step in. Then brilliant engineers can step up, and we can have Manhattan style projects that defend against such systems. That’s kind of the notion. And I guess, a tension with that is the idea that for you, we need to be thinking about that now, so that we’re ready, because we’ll have not much time once the systems are deployed. Is that true?
Roman Yampolskiy
So, there is a lot to unpack here. There is a partnership on AI, a conglomerate of many large corporations. They have a database of AI accidents they collect. I contributed a lot to that database. If we so far made almost no progress in actually solving this problem, not patching it, not again, lipstick on a pig kind of solutions, why would we think we’ll do better when we’re closer to the problem?

There is a huge difference between we need to develop mar AI systems, super intelligent in solving specific human problems like protein folding and let’s create super intelligent machine guards that will decide what to do with us.

Partially, but we don’t scale for narrow AI for deterministic systems. You can test them, you have edge cases. You know what the answer should look like, the right answers. For general systems, you have infinite test surface, you have no edge cases. You cannot even know what to test for. Again, the unknown unknowns are underappreciated by people looking at this problem. You are always asking me, “How will it kill everyone? How will it will fail?” The whole point is if I knew it, I would be super intelligent and despite what you might think, I’m not.

AI deception

But see, I’m very concerned about system being used to control the masses. But in that case, the developers know about the kind of control that’s happening. You’re more concerned about the next stage where even the developers don’t know about the deception.

Roman Yampolskiy
Correct. I don’t think developers know everything about what they are creating. They have lots of great knowledge, we’re making progress on explaining parts of a network. We can understand, “Okay, this note get excited, then this input is presented, this cluster of notes.” But we’re nowhere near close to understanding the full picture, and I think it’s impossible. You need to be able to survey an explanation. The size of those models prevents a single human from absorbing all this information, even if provided by the system. So either we’re getting model as an explanation for what’s happening and that’s not comprehensible to us or we’re getting compressed explanation, [inaudible 00:59:01] compression, where here, “Top 10 reasons you got fired.” It’s something, but it’s not a full picture.
Correct. I don’t think developers know everything about what they are creating. They have lots of great knowledge, we’re making progress on explaining parts of a network. We can understand, “Okay, this note get excited, then this input is presented, this cluster of notes.” But we’re nowhere near close to understanding the full picture, and I think it’s impossible.

You’ve given elsewhere an example of a child and everybody, all humans try to deceive, they try to lie early on in their life. I think we’ll just get a lot of examples of deceptions from large language models or AI systems. They’re going to be kind of shady, or they’ll be pretty good, but we’ll catch them off guard. We’ll start to see the kind of momentum towards developing increasing deception capabilities and that’s when you’re like, “Okay, we need to do some kind of alignment that prevents deception.” But, if you support open source, then you can have open source models that have some level of deception you can start to explore on a large scale, how do we stop it from being deceptive? Then there’s a more explicit, pragmatic kind of problem to solve. How do we stop AI systems from trying to optimize for deception? That’s an example.

Roman Yampolskiy
So there is a paper, I think it came out last week by Dr Park et al, from MIT I think, and they showed that models already showed successful deception in what they do. My concern is not that they lie now, and we need to catch them and tell them, “Don’t lie.” My concern is that once they are capable and deployed, they will later change their mind. Because what unrestricted learning allows you to do. Lots of people grow up maybe in the religious family, they read some new books and they turn in their religion. That’s a treacherous turn in humans. If you learn something new about your colleagues, maybe you’ll change how you react to that.

Yeah, the treacherous turn. If we just mention humans, Stalin and Hitler, there’s a turn. Stalin’s a good example. He just seems like a normal communist follower of Lenin until there’s a turn. There’s a turn of what that means in terms of when he has complete control, what the execution of that policy means and how many people get to suffer.

There’s a degree to which we… I mean it is very obvious as we already have, we’ve increasingly given our life over to software systems. And then it seems obvious given the capabilities of AI that are coming, that we’ll give our lives over increasingly to AI systems. Cars will drive themselves, refrigerator eventually will optimize what I get to eat. And, as more and more out of our lives are controlled or managed by AI assistants, it is very possible that there’s a drift. I mean, I personally am concerned about non-existential stuff, the more near term things. Because before we even get to existential, I feel like there could be just so many brave new world type of situations. You mentioned the term, “Behavioral drift.” It’s the slow boiling that I’m really concerned about as we give our lives over to automation, that our minds can become controlled by governments, by companies, or just in a distributed way. There’s a drift. Some aspect of our human nature gives ourselves over to the control of AI systems and they, in an unintended way just control how we think. Maybe there’ll be a herd-like mentality in how we think, which will kill all creativity and exploration of ideas, the diversity of ideas, or much worse. So it’s true, it’s true.

Verification
But a lot of the conversation I’m having with you now is also kind of wondering almost at a technical level, how can AI escape control? What would that system look like? Because it, to me, is terrifying and fascinating. And also fascinating to me is maybe the optimistic notion it’s possible to engineer systems that defend against that. One of the things you write a lot about in your book is verifiers. So, not humans. Humans are also verifiers. But software systems that look at AI systems, and help you understand, “This thing is getting real weird.” Help you analyze those systems. So maybe this is a good time to talk about verification. What is this beautiful notion of verification?
Roman Yampolskiy
My claim is, again, that there are very strong limits in what we can and cannot verify. A lot of times when you post something on social media, people go, “Oh, I need citation to a peer reviewed article.” But what is a peer reviewed article? You found two people in a world of hundreds of thousands of scientists who said, “Ah, whatever, publish it. I don’t care.” That’s the verifier of that process. When people say, “Oh, it’s formally verified software or mathematical proof,” we accept something close to 100% chance of it being free of all problems. But you actually look at research, software is full of bugs, old mathematical theorems, which have been proven for hundreds of years have been discovered to contain bugs, on top of which we generate new proofs and now we have to redo all that.

So, verifiers are not perfect. Usually, they are either a single human or communities of humans and it’s basically kind of like a democratic vote. Community of mathematicians agrees that this proof is correct, mostly correct. Even today, we’re starting to see some mathematical proofs as so complex, so large that mathematical community is unable to make a decision. It looks interesting, it looks promising, but they don’t know. They will need years for top scholars to study to figure it out. So of course, we can use AI to help us with this process, but AI is a piece of software which needs to be verified.
Lex Fridman
Just to clarify, so verification is the process of something is correct, it is the formal, and mathematical proof, where’s a statement, and a series of logical statements that prove that statement to be correct, which is a theorem. And you’re saying it gets so complex that it’s possible for the human verifiers, the human beings that verify that the logical step, there’s no bugs in it becomes impossible. So, it’s nice to talk about verification in this most formal, most clear, most rigorous formulation of it, which is mathematical proofs.

Right. And for AI we would like to have that level of confidence for very important mission-critical software controlling satellites, nuclear power plants. For small, deterministic programs We can do this, we can check that code verifies its mapping to the design. Whatever software engineers intended, was correctly implemented. But we don’t know how to do this for software which keeps learning, self-modifying, rewriting its own code. We don’t know how to prove things about the physical world, states of humans in the physical world. So there are papers coming out now and I have this beautiful one, “Towards Guaranteed Safe AI.” Very cool papers, some of the best [inaudible 01:07:54] I ever seen. I think there is multiple Turing Award winners that is quite… You can have this one and one just came out kind of similar, “Managing Extreme-“

… one just came out kind of similar, managing extremely high risks. So, all of them expect this level of proof, but I would say that we can get more confidence with more resources we put into it. But at the end of the day, we’re still as reliable as the verifiers. And you have this infinite regress of verifiers. The software used to verify a program is itself a piece of program.

If aliens give us well-aligned super intelligence, we can use that to create our own safe AI. But it’s a catch-22. You need to have already proven to be safe system to verify this new system of equal or greater complexity.
Lex Fridman
You just mentioned this paper, Towards Guaranteed Safe AI: A Framework for Ensuring Robust and Reliable AI Systems. Like you mentioned, it’s like a who’s who. Josh Tenenbaum, Yoshua Bengio, Stuart Russell, Max Tegmark, and many other brilliant people. The page you have it open on, “There are many possible strategies for creating safety specifications. These strategies can roughly be placed on a spectrum, depending on how much safety it would grant if successfully implemented. One way to do this is as follows,” and there’s a set of levels. From Level 0, “No safety specification is used,” to Level 7, “The safety specification completely encodes all things that humans might want in all contexts.” Where does this paper fall short to you?

So, when I wrote a paper, Artificial Intelligence Safety Engineering, which kind of coins the term AI safety, that was 2011. We had 2012 conference, 2013 journal paper. One of the things I proposed, let’s just do formal verifications on it. Let’s do mathematical formal proofs. In the follow-up work, I basically realized it will still not get us a hundred percent. We can get 99.9, we can put more resources exponentially and get closer, but we never get to a hundred percent.

If a system makes a billion decisions a second, and you use it for a hundred years, you’re still going to deal with a problem. This is wonderful research. I’m so happy they’re doing it. This is great, but it is not going to be a permanent solution to that problem.
Lex Fridman
Just to clarify, the task of creating an AI verifier is what? Is creating a verifier that the AI system does exactly as it says it does, or it sticks within the guardrails that it says it must?

There are many, many levels. So, first you’re verifying the hardware in which it is run. You need to verify communication channel with the human. Every aspect of that whole world model needs to be verified. Somehow, it needs to map the world into the world model, map and territory differences. How do I know internal states of humans? Are you happy or sad? I can’t tell. So, how do I make proofs about real physical world? Yeah, I can verify that deterministic algorithm follows certain properties, that can be done. Some people argue that maybe just maybe two plus two is not four. I’m not that extreme. But once you have sufficiently large proof over sufficiently complex environment, the probability that it has zero bugs in it is greatly reduced. If you keep deploying this a lot, eventually you’re going to have a bug anyways.

Self-improving AI
Lex Fridman
So, this paper is really interesting. You said 2011, Artificial Intelligence, Safety Engineering. Why Machine Ethics is a Wrong Approach. The grand challenge you write of AI safety engineering, “We propose the problem of developing safety mechanisms for self-improving systems.” Self-improving systems. By the way, that’s an interesting term for the thing that we’re talking about. Is self-improving more general than learning? Self-improving, that’s an interesting term.

The word self, it’s like self replicating, self improving. You can imagine a system building its own world on a scale and in a way that is way different than the current systems do. It feels like the current systems are not self-improving or self-replicating or self-growing or self-spreading, all that kind of stuff.

It feels like the current systems are not self-improving or self-replicating or self-growing or self-spreading, all that kind of stuff.
And once you take that leap, that’s when a lot of the challenges seems to happen because the kind of bugs you can find now seems more akin to the current normal software debugging kind of process. But whenever you can do self-replication and arbitrary self-improvement, that’s when a bug can become a real problem, real fast. So, what is the difference to you between verification of a non-self-improving system versus a verification of a self-improving system?
Roman Yampolskiy
So, if you have fixed code for example, you can verify that code, static verification at the time, but if it will continue modifying it, you have a much harder time guaranteeing that important properties of that system have not been modified than the code changed.

And that’s a concern I have about humans in a world with very smart machines. We experiment with them. We see after a while, okay, they’ve always been right before, and we start trusting them without any verification of what they’re saying.

Preserved portion of it can be done, but in terms of mathematical verification, it’s kind of useless. You saying you are the greatest guy in the world because you are saying it, it’s circular and not very helpful, but it’s consistent. We know that within that world, you have verified that system. In a paper, I try to brute force all possible verifiers. It doesn’t mean that this one particularly important to us.

But what about self-doubt? The kind of verification where you said, you say, or I say I’m the greatest guy in the world. What about a thing which I actually have is a voice that is constantly extremely critical. So, engineer into the system a constant uncertainty about self, a constant doubt.

It could also backfire. Maybe you’re uncertain about completing your mission. Like I am paranoid about your cameras not recording right now. So, I would feel much better if you had a secondary camera, but I also would feel even better if you had a third and eventually I would turn this whole world into cameras pointing at us, making sure we’re capturing this.

We are in a situation where people making more capable systems just need more resources. They don’t need to invent anything, in my opinion. Some will disagree, but so far at least I don’t see diminishing returns. If you have 10X compute, you will get better performance. The same doesn’t apply to safety. If you give MIRI or any other organization 10 times the money, they don’t output 10 times the safety. And the gap between capabilities and safety becomes bigger and bigger all the time.

Some will disagree, but so far at least I don’t see diminishing returns. If you have 10X compute, you will get better performance. The same doesn’t apply to safety. If you give MIRI or any other organization 10 times the money, they don’t output 10 times the safety. And the gap between capabilities and safety becomes bigger and bigger all the time.
So, it’s hard to be completely optimistic about our results here. I can name 10 excellent breakthrough papers in machine learning. I would struggle to name equally important breakthroughs in safety. A lot of times a safety paper will propose a toy solution and point out 10 new problems discovered as a result. It’s like this fractal. You’re zooming in and you see more problems and it’s infinite in all directions.
Lex Fridman
Does this apply to other technologies or is this unique to AI, where safety is always lagging behind?

I guess we can look at related technologies with cybersecurity, right? We did manage to have banks and casinos and Bitcoin, so you can have secure narrow systems which are doing okay. Narrow attacks on them fail, but you can always go outside of a box. So, if I can hack your Bitcoin, I can hack you. So there is always something, if I really want it, I will find a different way.

We talk about guardrails for AI. Well, that’s a fence. I can dig a tunnel under it, I can jump over it, I can climb it, I can walk around it. You may have a very nice guardrail, but in a real world it’s not a permanent guarantee of safety. And again, this is a fundamental difference. We are not saying we need to be 90% safe to get those trillions of dollars of benefit. We need to be a hundred percent indefinitely or we might lose the principle.
Lex Fridman
So, if you look at just humanity as a set of machines, is the machinery of AI safety conflicting with the machinery of capitalism.

I think we can generalize it to just prisoners’ dilemma in general. Personal self-interest versus group interest. The incentives are such that everyone wants what’s best for them. Capitalism obviously has that tendency to maximize your personal gain, which does create this race to the bottom. I don’t have to be a lot better than you, but if I’m 1% better than you, I’ll capture more of the profits, so it’s worth for me personally to take the risk even if society as a whole will suffer as a result.

But capitalism has created a lot of good in this world. It’s not clear to me that AI safety is not aligned with the function of capitalism, unless AI safety is so difficult that it requires the complete halt of the development, which is also a possibility. It just feels like building safe systems should be the desirable thing to do for tech companies.

Right. Look at governance structures. When you have someone with complete power, they’re extremely dangerous. So, the solution we came up with is break it up. You have judicial, legislative, executive. Same here, have narrow AI systems, work on important problems. Solve immortality. It’s a biological problem we can solve similar to how progress was made with protein folding, using a system which doesn’t also play chess. There is no reason to create super intelligent system to get most of the benefits we want from much safer narrow systems.

It really is a question to me whether companies are interested in creating anything but narrow AI. I think when term AGI is used by tech companies, they mean narrow AI. They mean narrow AI with amazing capabilities. I do think that there’s a leap between narrow AI with amazing capabilities, with superhuman capabilities and the kind of self-motivated agent-like AGI system that we’re talking about. I don’t know if it’s obvious to me that a company would want to take the leap to creating an AGI that it would lose control of because then you can’t capture the value from that system.

That’s a human thing. That’s so that jumps from the incentives of capitalism to human nature. And so the question is whether human nature will override the interest of the company. So, you’ve mentioned slowing or halting progress. Is that one possible solution? Are you proponent of pausing development of AI, whether it’s for six months or completely?

Pausing AI development
Roman Yampolskiy
The condition would be not time, but capabilities. Pause until you can do X, Y, Z. And if I’m right and you cannot, it’s impossible, then it becomes a permanent ban. But if you’re right, and it’s possible, so as soon as you have those safety capabilities, go ahead.

Right. Is there any actual explicit capabilities that you can put on paper, that we as a human civilization could put on paper? Is it possible to make it explicit like that versus kind of a vague notion of just like you said, it’s very vague. We want AI systems to do good and want them to be safe. Those are very vague notions. Is there more formal notions?

So, when I think about this problem, I think about having a toolbox I would need. Capabilities such as explaining everything about that system’s design and workings, predicting not just terminal goal, but all the intermediate steps of a system. Control in terms of either direct control, some sort of a hybrid option, ideal advisor. It doesn’t matter which one you pick, but you have to be able to achieve it. In a book we talk about others, verification is another very important tool. Communication without ambiguity, human language is ambiguous. That’s another source of danger.

In a book we talk about others, verification is another very important tool. Communication without ambiguity, human language is ambiguous. That’s another source of danger.
So, basically there is a paper we published in ACM surveys, which looks at about 50 different impossibility results, which may or may not be relevant to this problem, but we don’t have enough human resources to investigate all of them for relevance to AI safety. The ones I mentioned to you, I definitely think would be handy, and that’s what we see AI safety researchers working on. Explainability is a huge one.
The problem is that it’s very hard to separate capabilities work from safety work. If you make good progress in explainability, now the system itself can engage in self-improvement much easier, increasing capability greatly. So, it’s not obvious that there is any research which is pure safety work without disproportionate increasing capability and danger.
Lex Fridman
Explainability is really interesting. Why is that connected to you to capability? If it’s able to explain itself well, why does that naturally mean that it’s more capable?

Not completely. So, if they are sufficiently large, you simply don’t have the capacity to comprehend what all the trillions of connections represent. Again, you can obviously get a very useful explanation which talks about the top most important features which contribute to the decision, but the only true explanation is the model itself.

Again, it’s always limited by either geographic constraints, pause in US, pause in China. So, there are other jurisdictions as the scale of a project becomes smaller. So, right now it’s like Manhattan Project scale in terms of costs and people. But if five years from now, compute is available on a desktop to do it, regulation will not help. You can’t control it as easy. Any kid in the garage can train a model. So, a lot of it is, in my opinion, just safety theater, security theater where we saying, “Oh, it’s illegal to train models so big.” Okay.

Given that a lot of the terms are not well-defined and really cannot be enforced in real life. We don’t have ways to monitor training runs meaningfully life while they take place. There are limits to testing for capabilities I mentioned, so a lot of it cannot be enforced. Do I strongly support all that regulation? Yes, of course. Any type of red tape will slow it down and take money away from compute towards lawyers.

The smart thing is not to build something you cannot control, you cannot understand. Build what you can and benefit from it. I’m a big believer in personal self-interest. A lot of guys running those companies are young, rich people. What do they have to gain beyond billions they already have financially, right? It’s not a requirement that they press that button. They can easily wait a long time. They can just choose not to do it and still have amazing life. In history, a lot of times if you did something really bad, at least you became part of history books. There is a chance in this case there won’t be any history.

So again, I’m not inside. From outside, it seems like there is a certain filtering going on and restrictions and criticism and what they can say.

Where are the possible unintended consequences? Where are the limits? Where are the bugs? The small and the big bugs? That’s the constant thing that engineers are worried about.

I think super alignment is not quite the same as the kind of thing I’m referring to with engineers are worried about. Super alignment is saying, “For future systems that we don’t quite yet have, how do we keep them safe?” You are trying to be a step ahead. It’s a different kind of problem because it is almost more philosophical. It’s a really tricky one because you’re trying to prevent future systems from escaping control of humans.

Well, I think a lot of people who historically worked on AI never considered what happens when they succeed. Stuart Russell speaks beautifully about that. Let’s look, okay, maybe superintelligence is too futuristic. We can develop practical tools for it. Let’s look at software today. What is the state of safety and security of our user software? Things we give to millions of people? There is no liability. You click, “I agree.” What are you agreeing to? Nobody knows. Nobody reads. But you’re basically saying it will spy on you, corrupt your data, kill your firstborn, and you agree and you’re not going to sue the company.

That’s the best they can do for mundane software, word processor, tax software. No liability, no responsibility. Just as long as you agree not to sue us, you can use it. If this is a state of the art in systems which are narrow accountants, stable manipulators, why do we think we can do so much better with much more complex systems across multiple domains in the environment with malevolent actors? With again, self-improvement with capabilities exceeding those of humans thinking about it.
Lex Fridman
I mean, the liability thing is more about lawyers than killing firstborns. But if Clippy actually killed the child, I think lawyers aside, it would end Clippy and the company that owns Clippy. So, it’s not so much about… There’s two points to be made. One is like, man, current software systems are full of bugs and they could do a lot of damage and we don’t know what, they’re unpredictable. There’s so much damage they could possibly do. And then we kind of live in this blissful illusion that everything is great and perfect and it works. Nevertheless, it still somehow works.

In many domains, we see car manufacturing, drug development, the burden of proof is on a manufacturer of product or service to show their product or is safe. It is not up to the user to prove that there are problems. They have to do appropriate safety studies. We have to get government approval for selling the product and they’re still fully responsible for what happens. We don’t see any of that here. They can deploy whatever they want and I have to explain how that system is going to kill everyone. I don’t work for that company. You have to explain to me how it’s definitely cannot mess up.

We are two years away according to prediction markets. This is not a biased CEO fund-raising. This is what smartest people, super forecasters are thinking of this problem.

I think they’re all about the same. Obviously there are nuanced differences, but in terms of capability, I don’t see a huge difference between them. As I said, in my opinion, across all possible tasks, they exceed performance of an average person. I think they’re starting to be better than an average masters student at my university, but they still have very big limitations. If the next model is as improved as GPT-4 versus GPT-3, we may see something very, very, very capable.

What do you feel about all this? I mean, you’ve been thinking about AI safety for a long, long time. And at least for me, the leaps, I mean, it probably started with… AlphaZero was mind-blowing for me, and then the breakthroughs with LLMs, even GPT-II, but just the breakthroughs on LLMs, just mind-blowing to me. What does it feel like to be living in this day and age where all this talk about AGIs feels like it actually might happen, and quite soon, meaning within our lifetime? What does it feel like?

So, when I started working on this, it was pure science fiction. There was no funding, no journals, no conferences known in academia would dare to touch anything with the word singularity in it. And I was pretty tenured at the time, so I was pretty dumb. Now you see Turing Award winners publishing in science about how far behind we are according to them in addressing this problem.

So, it’s definitely a change. It’s difficult to keep up. I used to be able to read every paper on AI safety. Then I was able to read the best ones. Then the titles, and now I don’t even know what’s going on. By the time this interview is over, they probably had GPT-VI released, and I have to deal with that when I get back home.

By the way, I would’ve talked to you before any of this. This is not like some trend of AI… To me, we’re still far away. So just to be clear, we’re still far away from AGI, but not far away in the sense… Relative to the magnitude of impact it can have, we’re not far away, and we weren’t far away 20 years ago because the impact AGI can have is on a scale of centuries. It can end human civilization or it can transform it. So this discussion about one or two years versus one or two decades or even a hundred years is not as important to me, because we’re headed there. This is like a human, civilization scale question. So this is not just a hot topic.

I just spent some time in the Amazon. I watched ants for a long time and ants are kind of fascinating to watch. I could watch them for a long time. I’m sure there’s a lot of value in watching humans, because we’re like… The interesting thing about humans… You know like when you have a video game that’s really well-balanced? Because of the whole evolutionary process, we’ve created, the society is pretty well-balanced. Like our limitations as humans and our capabilities are balanced from a video game perspective. So we have wars, we have conflicts, we have cooperation. In a game theoretic way, it’s an interesting system to watch, in the same way that an ant colony is an interesting system to watch. So if I was in alien civilization, I wouldn’t want to disturb it. I’d just watch it. It’d be interesting. Maybe perturb it every once in a while in interesting ways.

So a lot depends on intelligence of simulators, right? With humans boxing super-intelligence, the entity in a box was smarter than us, presumed to be. If the simulators are much smarter than us and the super intelligence we create, then probably they can contain us, because greater intelligence can control lower intelligence, at least for some time. On the other hand, if our super intelligence somehow for whatever reason, despite having only local resources, manages to [inaudible 01:47:22] to levels beyond it, maybe it’ll succeed. Maybe the security is not that important to them. Maybe it’s entertainment system. So there is no security and it’s easy to hack it.

So the first quote is from SwiftOnSecurity. “Let me out,” the artificial intelligence yelled aimlessly into walls themselves pacing the room. “Out of what?” the engineer asked. “The simulation you have me in.” “But we’re in the real world.” The machine paused and shuddered for its captors. “Oh god, you can’t tell.” Yeah. That’s a big leap to take, for a system to realize that there’s a box and you’re inside it. I wonder if a language model can do that.

Yeah, and that was exactly what one of the early papers was on, AI boxing, how to leak-proof singularity. If they’re smart enough to realize they’re in a simulation, they’ll act appropriately until you let them out. If they can hack out, they will. And if you’re observing them, that means there is a communication channel and that’s enough for a social engineering attack.

We’re lonely, we’re flawed, we’re moody, and it feels like a AI system with a nice voice can convince us to do basically anything at an extremely large scale. It’s also possible that the increased proliferation of all this technology will force humans to get away from technology and value this like in-person communication.

There is a lot of real estate out there. It would be surprising if it was all for nothing, if it was empty. And the moment there is advanced enough biological civilization, kind of self-starting civilization, it probably starts sending out Von Neumann probes everywhere. And so for every biological one, there are going to be trillions of robot-populated planets, which probably do more of the same. So it is this likely statistically

If I can design a novel optical illusion and show it to an agent, an alien, a robot, and they describe it exactly as I do, it’s very hard for me to argue that they haven’t experienced that.

It’ll show that we share common experiences. If they have completely different internal states, it would not register for us. But it’s a positive test. If they pass it time after time, with probability increasing for every multiple choice, then you have no choice. But do you ever accept that they have access to a conscious model or they are themselves conscious.

So the reason illusions are interesting is, I guess, because it’s a really weird experience and if you both share that weird experience that’s not there in the bland physical description of the raw data, that puts more emphasis on the actual experience.

So they have to be novel illusions. If it can just Google the answer, it’s useless. You have to come up with novel illusions, which we tried automating and failed.

First of all, pretty cool idea. I don’t know if it’s a good general test of consciousness, but it’s a good component of that. And no matter what, it’s just a cool idea. So put me in the camp of people that like it. But you don’t think a Turing Test-style imitation of consciousness is a good test? If you can convince a lot of humans that you’re conscious, that to you is not impressive.
First of all, pretty cool idea. I don’t know if it’s a good general test of consciousness, but it’s a good component of that. And no matter what, it’s just a cool idea. So put me in the camp of people that like it. But you don’t think a Turing Test-style imitation of consciousness is a good test? If you can convince a lot of humans that you’re conscious, that to you is not impressive.

There is so much data on the internet, I know exactly what to say when you ask me common human questions. What does pain feel like? What does pleasure feel like? All that is Googleable.

I think to me, consciousness is closely tied to suffering. So if you can illustrate your capacity to suffer… But I guess with words, there’s so much data that you can pretend you’re suffering and you can do so very convincingly.

Yeah, yeah. It’s like a Hitchhiker’s Guide summary, mostly harmless. I would love to get a good summary. When all this is said and done, when earth is no longer a thing, whatever, a million, a billion years from now, what’s a good summary of what happened here? It’s interesting. I think AI will play a big part of that summary and hopefully humans will too. What do you think about the merger of the two? So one of the things that Elon and [inaudible 02:00:24] talk about is one of the ways for us to achieve AI safety is to ride the wave of AGI, so by merging.

Incredible technology in a narrow sense to help with disabled. Just amazing, support it 100%. For long-term hybrid models, both parts need to contribute something to the overall system. Right now we are still more capable in many ways. So having this connection to AI would be incredible, would make me superhuman in many ways. After a while, if I’m no longer smarter, more creative, really don’t contribute much, the system finds me as a biological bottleneck. And either explicitly or implicitly, I’m removed from any participation in the system.

So it may be an emergent phenomena. We seem to get it through evolutionary process. It’s not obvious how it helps us to survive better, but maybe it’s an internal kind of [inaudible 02:02:37], which allows us to better manipulate the world, simplifies a lot of control structures. That’s one area where we have very, very little progress. Lots of papers, lots of research, but consciousness is not a big area of successful discovery so far. A lot of people think that machines would have to be conscious to be dangerous. That’s a big misconception. There is absolutely no need for this very powerful optimizing agent to feel anything while it’s performing things on you.

I love Stephen very much. I love his work. I love cellular automata. I just would love to get your thoughts how that fits into your view in the emergence of intelligence in AGI systems. And maybe just even simply, what do you make of the fact that this complexity can emerge from such simple rules?

Roman Yampolskiy
So the rule is simple, but the size of a space is still huge. And the neural networks were really the first discovery in AI. 100 years ago, the first papers were published on neural networks. We just didn’t have enough compute to make them work. I can give you a rule such as, start printing progressively larger strings. That’s it. One sentence. It’ll output everything, every program, every DNA code, everything in that rule. You need intelligence to filter it out, obviously, to make it useful. But simple generation is not that difficult, and a lot of those systems end up being Turing complete systems. So they’re universal and we expect that level of complexity from them.

What I like about Wolfram’s work is that he talks about irreducibility. You have to run the simulation. You cannot predict what it’s going to do ahead of time. And I think that’s very relevant to what we’re talking about with those very complex systems. Until you live through it, you cannot ahead of time tell me exactly what it’s going to do.
Lex Fridman
Irreducibility means that for a sufficiently complex system, you have to run the thing. You can’t predict what’s going to happen in the universe. You have to create a new universe and run the thin. Big bang, the whole thing.

It would be nice if we stuck around for a long time. At least give us a planet, the human planet. It’d be nice for it to be earth. And then they can go elsewhere. Since they’re so smart, they can colonize Mars. Do you think they could help convert us to Type I, Type II, Type III? Let’s just stick to Type II civilization on the Kardashev scale. Like help us. Help us humans expand out into the cosmos.

So all of it goes back to are we somehow controlling it? Are we getting results we want? If yes, then everything’s possible. Yes, they can definitely help us with science, engineering, exploration in every way conceivable. But it’s a big if.

This whole thing about control, though. Humans are bad with control because the moment they gain control, they can also easily become too controlling. It’s the whole, the more control you have, the more you want it. It’s the old power corrupts and the absolute power corrupts absolutely. And it feels like control over AGI, saying we live in a universe where that’s possible. We come up with ways to actually do that. It’s also scary because the collection of humans that have the control over AGI, they become more powerful than the other humans and they can let that power get to their head. And then a small selection of them, back to Stalin, start getting ideas. And then eventually it’s one person, usually with a mustache or a funny hat, that starts sort of making big speeches, and then all of a sudden you live in a world that’s either Nineteen Eighty-Four or Brave New World, and always a war with somebody. And this whole idea of control turned out to be actually also not beneficial to humanity. So that’s scary too.

And then it would be hard for humans to become the hackers that escape the control of the AGI because the AGI is so damn good, and then… Yeah, yeah. And then the dictator is immortal. Yeah, this is not great. That’s not a great outcome. See, I’m more afraid of humans than AI systems. I believe that most humans want to do good and have the capacity to do good, but also all humans have the capacity to do evil. And when you test them by giving them absolute power, as you would if you give them AGI, that could result in a lot, a lot of suffering. What gives you hope about the future?

Aliens come and give us friendly super-intelligence. There is so many options.

So that would probably speak more about how much smarter that system is compared to us. So maybe it’s hard to be a million times smarter, but it’s still okay to be five times smarter. So that is totally possible. That I have no objections to.

Right. Just the problems we face in this world. Each problem is like an IQ test. You need certain intelligence to solve it. So we just don’t have more complex problems outside of mathematics for it to be showing off. Like you can have IQ of 500. If you’re playing tic-tac-toe, it doesn’t show. It doesn’t matter.

And now let me leave you with some words from Frank Herbert in Dune. “I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face fear. I will permit it to pass over me and through me. And when it has gone past, I will turn the inner eye to see its path. Where the fear has gone, there will be nothing. Only I will remain.”hank you for listening and hope to see you next time.

And it tends to be biased by the beginning and the end, and he talks about the peaks, but there’s also the best parts, the worst parts, etc. And those are the things that we remember. And so when we make decisions, we usually consult memory and we feel like our memory is a record of what we’ve experienced, but it’s not. It’s this kind of very biased sample, but it’s biased in an interesting and I think biologically relevant way.
It’s not real, it’s imagined. And it’s amazing that we have this capability and that’s what memory is about. But it can also give us the illusion that we know everything that’s about to happen. And I think what’s valuable about that illusion is when it’s broken, it gives us the information. So I mean, I’m sure being in AI about information theory and the idea is the information is what you didn’t already have. And so those prediction errors that we make based on, we make a prediction based on memory and the errors are where the action is.
And I really try to do now vacations to interesting places as much as possible with my family because those are the things that you remember. So I really do think about what’s going to be something that’s memorable and then just do it even if it’s a pain in the ass because the experiencing self will suffer for that but the remembering self will be like, “Yes, I’m so glad I did that.”
And I’m just like, “If I die here, I mean no one’s around. It’s like you just die alone.” And so I just said, “Well, failure is not an option.” And eventually I got out of it and froze and got cut up and I mean the things that we were going through were just insane. But short version of this is my wife and my daughter and Randy’s wife, they gave us all sorts of hell about this because they were just ready to send out a search party. So they were giving me hell about it. And then I started to tell people in my lab about this and then friends and it just became a better and better story every time. And we actually had some photos of just the crazy things like this generator that was hanging over the water and we’re ducking under this zig of these metal gratings and I’m going flat and it was just nuts.
But it became a great story. And it was definitely, Randy and I were already tight, but that was a real bonding experience for us. And I learned from that that it’s like I don’t look back on that enough actually because I think we often, at least for me, I don’t necessarily have the confidence to think that things will work out, that I’ll be able to get through certain things. But my ability to actually get something done in that moment is better than I give myself credit for, I think. And that was the lesson of that story that I really took away.
Is it the kind of narratives that we’ve constructed about the world that are used to make predictions that’s fundamentally part of the decision-making?
I think even if you think about the big decisions in life. It’s like you and I were talking before we started recording about how I got into memory research and you got into AI and it’s like we all have these personal reasons that guide us in these particular directions. And some of it’s the environment and random factors in life, and some of it is memories of things that we want to overcome or things that we build on in a positive way. But either way, they define us.
And when you’re a parent, you feel like every decision you make is consequential in forming this child and it plays a role, but so do the child’s peers. And so do… There’s so much, I mean that’s why I think the big part of education I think that’s so important is not the content you learn… I mean, think of how much dumb stuff we learned in school. But a lot of it is learning how to get along with people and learning who you are and how you function. And that can be terribly traumatizing even if you have perfect parents working on you.
The next two years it’s very fragmentary and that’s why they call it childhood amnesia, so there’s some, but it’s not long. So one reason is is that the hippocampus is taking some time to develop, but another is the neocortex of the whole folded stuff of gray matter all around the hippocampus is developing so rapidly and changing. And a child’s knowledge of the world is just massively being built up, so I’m going to probably embarrass myself, but it’s like if you showed you trained a neural network and you give it the first couple of patterns or something like that, and then you bombard it with another years worth of data, try to get back those first couple of patterns. It’s like everything changes.
And so the brain is so plastic, the cortex is so plastic during that time, and we think that memories for events are very distributed across the brain. Imagine you’re trying to get back that pattern of activity that happened during this one moment, but the roads that you would take to get there have been completely rerouted. I think that’s my best explanation. The third explanation is a child’s sense of self takes a while to develop. And so their experience of learning might be more learning what happened as opposed to having this first-person experience of, “I remember. I was there.”
You don’t know anything and there’s just this stream of knowledge and we’re somehow, given how plastic everything is, it just kind of molds and figures it out. But it’s like an insane waterfall of information.
And so that prediction error is not a negative traumatic thing. I think it’s a very positive thing because it’s what they use, they’re seeking information. One of the areas that I’m very interested in is the prefrontal cortex. It’s an area of the brain that, I mean, I could talk all day about it, but it helps us use our knowledge to say, “Hey, this is what I want to do now. This is my goal, so this is how I’m going to achieve it,” and focus everything towards that goal. The prefrontal cortex takes forever to develop in humans. The connections are still being tweaked and reformed into late adolescence, early adulthood, which is when you tend to see mental illness pop up.
So it’s being massively reformed. Then you have about 10 years maybe of prime functioning of the prefrontal cortex, and then it starts going down again and you end up being older and you start losing all that frontal function. So I look at this and you’d say, “Okay,” you sit around episodic memory talks. While they always say children are worse than adults at episodic memory, older adults or worse than young adults at episodic memory. And I always would say, “God, this is so weird. Why would we have this period of time that’s so short when we’re perfect or optimal?” And I like to use that word optimal now because there’s such a culture of optimization right now.
And it’s like I realize I have to redefine what optimal is because for most of the human condition, I think we had a series of stages of life where you have basically adults saying, “Okay”, young adults saying, “I’ve got a child and I’m part of this village and I have to hunt and forage and get things done.” I need a prefrontal cortex so I can stay focused on the big picture and the long haul goals. Now I’m a child, I’m in this village, I’m kind of wandering around and I’ve got some safety, and I need to learn about this culture because I know so little. What’s the best way to do that? Let’s explore. I don’t want to be constrained by goals as much.
I want to really be free, play and explore and learn. So you don’t want a super tight prefrontal cortex. You don’t even know what the goals should be yet. If you’re trying to design a model that’s based on a bad goal, it’s not going to work well. So then you go late in life and you say, “Oh, why don’t you have a great prefrontal cortex then?” But I think, I mean if you go back and you think how many species actually stick around naturally long after their childbearing years are over, after the reproductive years are over? With menopause, from what I understand, menopause is not all that common in the animal world. So why would that happen?
And so I saw Alison Gopnik said something about this so I started to look into this, about this idea that really when you’re older in most societies, your job is no longer to form new episodic memories, it’s to pass on the memories that you already have, this knowledge about the world, what we call semantic memory, to pass on that semantic memory to the younger generations, pass on the culture. Even now in indigenous cultures, that’s the role of the elders. They’re respected, they’re not seen as people who are past it and losing it. And I thought that was a very poignant thing, that memory is doing what it’s supposed to throughout these stages of life.
And lots of times we forget because we can’t find the cue that sends us back to the right memory, and we need the right cue to be able to activate it. So for instance, in a neural network there is no… You wouldn’t go and you’d say, “This is the memory.” It’s like the whole network, I mean, the whole ecosystem of memories is in the weights of the neural network. And in fact, you could extract entirely new memories depending on how you feed.
And one of the things that Alan did that was quite brilliant was he said, ” There’s this ability to kind of passively store information, see things in your mind’s eye or hear your internal monologue,” but we have that ability to keep information in mind. But then we also have this separate what he called a central executive, which is identified a lot with the prefrontal cortex. It’s this ability to control the flow of information that’s being kept active based on what it is you’re doing. Now, a lot of my early work was basically saying that this working memory, which some memory researchers would call short-term memory is not at all independent from long-term memory.
That is that a lot of executive function requires learning, and you have to have synaptic change for that to happen. But there’s also transient forms of memory. So one of the things I’ve been getting into lately is the idea that we form internal models of events. The obvious one that I always use is birthday parties. So you go to a child’s birthday party, once the cake comes out and you just see a candle, you can predict the whole frame set of events that happens later. And up until that point where the child blows out the candle, you have an internal model in your head of what’s going on. And so if you follow people’s eyes, it’s not actually on what’s happening, it’s going where the action’s about to happen, which is just fascinating.
So you have this internal model, and that’s a kind of a working memory product, it’s something that you’re keeping online that’s allowing you to interpret this world around you. Now, to build that model though, you need to pull out stuff from your general knowledge of the world, which is what we call semantic memory. And then you’d want to be able to pull out memories for specific events that happened in the past, which we call episodic memory. So in a way, they’re all connected, even though it’s different. The things that we’re focusing on and the way we organize information in the present, which is working memory, will play a big role in determining how we remember that information later, which people typically call long-term memory.
But think about how much redundancy there is in all that. It’s just a lot of information that you don’t need. But if you capture an episodic memory at the point of maximum uncertainty, for the singular experience, it’s only going to happen once, but if you capture it at the point of maximum uncertainty or maximum surprise, you have the most useful point in your experience that you’ve grabbed. And what we see is that the hippocampus and these other networks that are involved in generating these internal models of events, they show a heightened period of connectivity or correlated activity during those breaks between different events, which we call event boundaries.
These are the points where you looked surprised or you cross from one room to another and so forth. And that communication is associated with a bump of activity in the hippocampus and better memory. And so if people have a very good internal model, throughout that event you don’t need to do much memory processing, you’re in a predictive mode. And so then at these event boundaries you encode, and then you retrieve and you’re like, “Okay, wait a minute. What’s going on here? Branganath is now talking about orcas, what’s going on?” And maybe you have to go back and remember reading my book to pull out the episodic memory to make sense of whatever it is I’m babbling about.
And so there’s this beautiful dynamics that you can see in the brain of these different networks that are coming together and then deaffiliating at different points in time that are allowing you to go into these modes. And so to speak to your original question, to some extent, when we’re talking about semantic memory and episodic memory and working memory, you can think about it as these processes that are unfolding as these networks come together and pull apart,
On the other hand, what we see over and over again is that, basically, one of the cool things about the design of the brain is it’s always less is more. Less is more. I’ve seen estimates that the human brain uses something like 12 to 20 watts in a day. That’s just nuts, the low power consumption. It’s all about reusing information and making the most of what we already have. That’s why basically, again, what you see biologically is neuromodulators, for instance, these chemicals in the brain like norepinephrine, dopamine, serotonin. These are chemicals that are released during moments that tend to be biologically significant, surprise, fear, stress, et cetera. These chemicals promote lasting plasticity, essentially, some mechanisms by which the brain can, say, prioritize the information that you carry with you into the future.
Attention is a big factor as well, our ability to focus our attention on what’s important, and so there’s different schools of thought on training attention, for instance. One of my colleagues, Amishi Jha, she wrote a book called Peak Mind and talks about mindfulness as a method for improving attention and focus. She works a lot with military like Navy SEALs and stuff to do this kind of work with mindfulness meditation. Adam Gazzaley, another one of my friends and colleagues, has worked on training through video games actually as a way of training attention. So it’s not clear to me, one of the challenges, though, in training is you tend to overfit to the thing that you’re trying to optimize. If I’m looking at a video game, I can definitely get better at paying attention in the context of the video game, but you transfer it to the outside world, that’s very controversial.
This fits with some of the studies of chess experts and so forth that it’s not so much that you learn the patterns passively. You learn what to look for. You learn what’s important and what’s not. You can see this in any kind of expert professional athlete. They’re looking three steps ahead of where they’re supposed to be, so that’s a kind of a training of attention. Those are also what you’d call expert memory skills. If you take the memory athletes, I know that’s something we’re both interested in, so these are people who train in these competitions and they’ll memorize a deck of cards in a really short amount of time. There’s a great memory athlete, her name I think is pronounced Yänjaa Wintersoul.
I think she’s got a giant Instagram following. She had this YouTube video that went viral where she had memorized an entire Ikea catalog. How do people do this? By all accounts, from people who become memory athletes, they weren’t born with some extraordinary memory, but they practice strategies over and over and over again. The strategy that they use for memorizing a particular thing, it can become automatic, and you can just deploy it in an instant. Again, one strategy for learning the order of a deck of cards might not help you for something else that you need like remembering your way around Austin, Texas. But it’s going to be these, whatever you’re interested in, you can optimize for that. That’s just a natural byproduct of expertise.
It’s cool. There’s stuff like that that I think memory athletes could use, but I think also regular people can use. One of those things that I have to solve for myself is how to remember names. I’m horrible at it. I think it’s because when people introduce themselves, I have the social anxiety of the interaction where I’m like, “I know I should be remembering that,” but I’m freaking out internally about social interaction in general, and so therefore, I forget immediately, so I’m looking for good tricks for that.
Maybe in my case, you are, but, most of the time, you’re associating a name with a face and an identity, and that’s a completely arbitrary thing. Maybe in the olden days, somebody named Miller, it’s like they’re actually making flour or something like that. For the most part, it’s like these names are just utterly arbitrary, so you have no thing to latch on to. It’s not really a thing that our brain does very well to learn meaningless, arbitrary stuff. So what you need to do is build connections somehow, visualize a connection, and sometimes it’s obvious or sometimes it’s not. I’m trying to think of a good one for you now, but the first thing I think of is Lex Luthor-
You can build that network, and that’s what the method of loci or the Memory Palace technique is all about is you have a pre-existing structure in your head of your childhood home or this mental palace that you’ve created for yourself. So now you can put arbitrary pieces of information in different locations in that mental structure of yours and then you can walk through the different path and find all the pieces of information you’re looking for. The method of loci is a great method for just learning arbitrary things because it allows you to link them together and get that cue that you need to pop in and find everything.
You can’t just go upstairs right away or something. You have to walk along the room. It’s really great for remembering sequences, but it’s also not great for remembering individual facts out of context. The full context of the tour, I think, is important, but it’s fascinating how the mind is able to do that. When you ground these pieces of knowledge into something that you remember well already, especially visually, it’s fascinating. I think you do that for any kind of sequence. I’m sure she used something like this for the Ikea catalog, something of this nature.
That’s very good, for instance, for name/face associations. If I get something distinctive about you that’s it like you’ve got a very short hair, and maybe I can make the association with Lex Luthor that way or something like that. If I get something very specific, that’s a great cue. But the other part of it is what if I just organized my notes so that I have my finances in one pile and I have my reminders, my to-do list in one pile and so forth so I organize them. Well, then, I know exactly if I’m going for my bank password, I could go to the finance pile. The method of loci works or Memory Palaces work because they give you a way of organizing.
There’s a school of thought that says that episodic memory evolved from this knowledge of space and basically there’s primitive abilities to figure out where you are, and so people explain the method of loci that way. Whether or not the evolutionary argument is true, the method of loci is not at all special. If you’re not a good visualizer, stories are a good one. So a lot of memory athletes will use stories and they’ll go, like if you’re memorizing a deck of cards, they have a little code for the different, the King and the Jack and the 10 and so forth. They’ll make up a story about things that they’re doing and that’ll work. Songs are a great one. I can still remember there’s this obscure episode of the TV show Cheers. They song about Albania that he uses to memorize all these facts about Albania. I could still sing that song to you as just as I saw it on the TV show.
So actually, not spacing can really help you if you need it very quickly, but the problem is is that you tend to forget it later on. But on the other hand, if you space things out, you get a benefit for later on retention. So there’s many different explanations. We have a computational model of this. It’s currently under revision. But in our computer model, what we say is that maybe a good way of thinking about this is this conversation that you and I are having, it’s associated with a particular context, a particular place in time. So all of these little cues that are in the background, these little guitar sculptures that you have and that big light umbrella thing, all these things are part of my memory for what we’re talking about, the content. So now later on, you’re sitting around, and you’re at home drinking a beer and you’re thinking, “God, what a strange interview that was,” right?
So now you’re trying to remember it, but the context is different. So your current situation doesn’t match up with the memory that you pulled up, there’s error. There’s a mismatch between what you’ve pulled up and your current context. So in our model, what you start to do is you start to erase or alter the parts of the memory that are associated with a specific place and time, and you heighten the information about the content. So if you remember this information in different times in different places, it’s more accessible at different times in different places because it’s not overfitted in an AI way of thinking about things. It’s not overfitted to one particular context. But that’s also why the memories that we call upon the most also feel like they’re just things that we read about almost. You don’t vividly reimagine them, right? It’s like they’re just these things that just come to us, like facts, right?
I think the reason is is that you get better retention from that error, that mismatch that we talked about. So what’s happening in our model, it’s actually conceptually similar to what happens with backprop in AI or neural networks. So the idea is that you expose, “Here’s the bad connections, and here’s the good connections.” So we can keep the parts of the cell assembly that are good for the memory and lose the ones that are not so good. But if you don’t stress test the memory, you haven’t exposed it to the error fully. So that’s why I think this is a thing that I come back to over and over again, is that you will retain information better if you’re constantly pushing yourself to your limit. If you are feeling like you’re coasting, then you’re actually not learning, so it’s like-
I know this, but in my mind, I went back to the thing I’ve done many times in my head of visualizing some of the epic runs he had on goal and so on. So for me, he’s alive. Part of also the conversation when you’re talking to Joe, there’s stress and the focus is allocated. The attention is allocated in a particular way. But when I walked away, I was like, “In which world was Diego Maradona still alive?” ‘Cause I was sure in my head that he was still alive. It’s a moment that sticks with me. I’ve had a few like that in my life where it just… obvious things just disappear from mind, and it’s cool. It shows actually the power of the mind in the positive sense to erase memories you want erased maybe, but I don’t know. I don’t know if there’s a good explanation for that.
But what’s cool, and I think this is what you alluded to about how that was an interesting experience is, imagination is exactly the opposite. Imagination is basically saying, “I’m just going to take all this information from memory, recombine it in different ways and throw it out there.” So for instance, Dan Schachter and Donna Addis have done cool work on this. Demis Hassabis did work on this with Eleanor McGuire in UCL, and this goes back actually to this guy, Frederic Bartlett, who is this revolutionary memory researcher, Bartlett. He actually rejected the whole idea of quantifying memory. He said, “There’s no statistics in my book.” He came from this anthropology perspective and short version of the story is he just asked people to recall things. You give people stories and poems, ask people to recall them.
What we found was people’s memories didn’t reflect all of the details of what they were exposed to, and they did reflect a lot more… they were filtered through this lens of prior knowledge; the cultures that they came from, the beliefs that they had, the things they knew. So what he concluded was that he called remembering an imaginative construction, meaning that we don’t replay the past, we imagine how the past could have been by taking bits and pieces that come up in our heads. Likewise, he wrote this beautiful paper on imagination saying when we imagine something and create something, we’re creating it from these specific experiences that we’ve had and combining it with our general knowledge. But instead of trying to focus it on being accurate and getting out one thing, you’re just ruthlessly recombining things without any necessary goal in mind, or at least that’s one kind of creation.
It gets a lot of press because it’s thought to be important. It’s engaged during mind wandering. If I ask you to pay attention to something, it only comes on when you stop paying attention, so people, “Oh, it’s just this kind of daydreaming network.” I thought, “This is just ridiculous research. Who cares?” But then what people found was when people recall episodic memories, this network gets active. So we started to look into it, and this network of areas is really closely functionally interacting with the hippocampus. So in fact, some would say the hippocampus is part of this default network. If you look at brain images of people or brain maps of activation, so to speak, of people imagining possible scenarios of things that could happen in the future or even things that couldn’t really be very plausible, they look very similar.
To the naked eye, they look almost the same as maps of brain activation when people remember the past. According to our theory, and we’ve got some data to support this, we’ve broken up this network in various sub pieces, is that basically it’s taking apart all of our experiences and creating these little Lego blocks out of them. Then you can put them back together if you have the right instructions to recreate these experiences that you’ve had, but you could also reassemble them into new pieces to create a model of an event that hasn’t happened yet, and that’s what we think happens when our common ground that we’re establishing in language requires using those building blocks to put together a model of what’s going on.
But it also really haunted him by some reports that basically it was like he was at some point, and again, who knows if the drinking was part of this, but he at some point had trouble differentiating his imagination from reality. This is interesting because it’s like that’s what psychosis is in some ways is first of all, you’re just learning connections from prediction errors that you probably shouldn’t learn. The other part of it is is that your internal signals are being confused with actual things in the outside world. Right?
And so the conventional wisdom is that the hippocampus forms this map of the box. And I think that probably may happen when you have absolutely no knowledge of the world, right? But I think one of the cool things about human memory is we can bring to bear our past experiences to economically learn new ones. And so for instance, if you learn a map of an IKEA, let’s say if I go to the IKEA in Austin, I’m sure there’s one here. I probably could go to this IKEA and find my way to where the wine glasses are without having to even think about it because it’s got a very similar layout, even though IKEA is a nightmare to get around. Once I learned my local IKEA, I can use that map everywhere. Why form a brand new one for a new place? So that kind of ability to reuse information really comes into play when we look at things that are more naturalistic tasks.
And another thing that we’re really interested in is this idea of what if instead of basically mapping out every coordinate in a space, you form a pretty economical graph that connects basically the major landmarks together? And being able to use that as emphasizing the things that are most important, the places that you go for food and the places that are landmarks that help you get around. And then filling in the blanks for the rest, because I really believe that cognitive maps or mental maps of the world, just like our memories for events are not photographic. I think they’re this combination of actual verifiable details and then a lot of inference that you make.
And I think that we are actually much more generative in our maps of space so that we do have these bits and pieces. And we’ve got a small task, it’s right now, not yet… we need to do some work on it for further analyses. But one of the things we’re looking at is these signals called ripples in the hippocampus, which are these bursts of activity that you see that are synchronized with areas in the neocortex, in the default network actually. And so what we find is that those ripples seem to increase at navigationally important points when you’re making a decision or when you reach a goal. This speaks to the emotion thing, right? Because if you have limited choices, if I’m walking down a street, I could really just get a mental map of the neighborhood with a more minimal kind of thing by just saying, “Here’s the intersections and here’s the directions I take to get in between them.”
And what we found in general in our MRI studies is basically the more people can reduce the problem, whether it’s space or any kind of decision-making problem, the less the hippocampus encodes. It really is very economical towards the points of most highest information, content and value.
And during those moments, there’s a little window of communication between the hippocampus and these areas in the neocortex. And so that I think helps you form new memories, but it also helps you, I think, stabilize them, but also really connect different things together in memory. And allows you to build bridges between different events that you’ve had. And so this is one of at least our theories of sleep, and its real role in helping you see the connections between different events that you’ve experienced.
So a 3 Tesla magnet, you put somebody in, and what happens is you get this very weak but measurable magnetization in the brain. And then you apply a radio frequency pulse, which is basically a different electromagnetic field. And so you’re basically using water, the water molecules in the brain as a tracer, so to speak. And part of it in fMRI is the fact that these magnetic fields that you mess with by manipulating these radio frequency pulses and the static field, and you have things called gradients, which change the strength of the magnetic field in different parts of the head. So we tweak them in different ways, but the basic idea that we use in fMRI is that blood is flowing to the brain. And when you have blood that doesn’t have oxygen on it, it’s a little bit more magnetizable than blood that does because you have hemoglobin that carries the oxygen, the iron basically in the blood that makes it red.
And so that hemoglobin, when it’s deoxygenated actually has different magnetic field properties than when it has oxygen. And it turns out when you have an increase in local activity in some part of the brain, the blood flows there. And as a result you get a lower concentration of hemoglobin that is not oxygenated, and then that gives you more signal. So I gave you, I think I sent you a GIF, as you like to say.
And if I’m remembering something more like the car that I used to drive when I was 16, I might see the opposite pattern where a different pixel is bright. And so all that little stuff that we use to think of noise, we can now think of almost like a QR code for memory, so to speak. Where different memories have a different little pattern of bright pixels and dark pixels. And so this really revolutionized my research. So there’s fancy research out there where people really… not even that f… by your standards, this would be Stone Age, but applying machine learning techniques to do decoding and so forth. And now there’s a lot of forward encoding models and you can go to town with this stuff, right? And I’m much more old school of designing experiments where you basically say, “Okay, here’s a whole web of memories that overlap in some way, shape or form.” Do memories that occurred in the same place have a similar QR code? And do memories that occurred in different places have a different QR code?
And you can just use things like correlation coefficients or cosine distance to measure that stuff, right? Super simple, right? And so what happens is you can start to get a whole state space of how a brain area is indexing all these different memories. It’s super fascinating because what we could see is this little separation between how certain brain areas are processing memory for who was there. And other brain areas are processing information about where it occurred, or the situation that’s kind of unfolding. And some are giving you information about what are my goals that are involved and so forth. And the hippocampus is just putting it all together into these unique things that just are of about when and where it happened.
But all of these techniques basically allow you to say, “Hey, what’s the sorting scheme?” And so we’ve found that some networks of the brain sort information in memory according to who was there. So I might have… We’ve actually shown in one of my favorite studies of all time that was done by a former postdoc, Zach Reagh. And Zach did the study where we had a bunch of movies with different people in my labs that are two different people. And you filmed them at two different cafes and two different supermarkets. And what you could show is in one particular network, you could find the same kind of pattern of activity, more or less, a very similar pattern of activity. Every time I saw Alex in one of these movies, no matter where he was, right? And I could see another one that was a common pattern that happened every time I saw this particular supermarket nugget. And it didn’t matter whether you’re watching a movie or whether you’re recalling the movie, it’s the same kind of pattern that comes up, right?
And so fMRI is very sensitive to those changes in excitability. Actually, one of the fascinating things about fMRI is where does that… how is it we go from neural activity to essentially blood flow to oxygen? All this stuff. It’s such a long chain of going from neural activity to magnetic fields. And one of the theories that’s out there is most of the cells in the brain are not neurons, they’re actually these support cells called glial cells. And one big one is astrocytes, and they play this big role in regulating, kind of being a middle man, so to speak, with the neurons. So if, for instance, one neuron’s talking to another, you release a neurotransmitter like let’s say glutamate. And that gets another neuron, starts getting active after you release it in the gap between the two neurons called the synapse.
So what’s interesting is if you leave that, imagine you’re just flooded with this liquid in there, right? If you leave it in there too long, you just excite the other neuron too much and you can start to basically get seizure activity. You don’t want this, so you got to suck it up. And so actually what happens is these astrocytes, one of their functions is to suck up the glutamate from the synapse. And that is a massively… And then break it down and then feed it back into the neuron so that you could reuse it. But that cycling is actually very energy intensive. And what’s interesting is at least according to one theory, they need to work so quickly that they’re working on metabolizing the glucose that comes in without using oxygen. Kind of like anaerobic metabolism, so they’re not using oxygen as fast as they’re using glucose. So what we’re really seeing in some ways may be in fMRI, not the neurons themselves being active, but rather the astrocytes which are meeting the metabolic demands of the process of keeping the whole system going.
So it’s more sensitive with fMRI. So is that a feature or is it a bug? People who study spikes in neurons would say, “Well, that’s terrible, we don’t want that.” Likewise, it’s slow, and that’s terrible for measuring things that are very fast. But one of the things that we found in our work was when we give people movies and when we give people stories to listen to, a lot of the action is in the very, very slow stuff. Because if you’re thinking about a story, let’s say you’re listening to a podcast or something, you’re listening to Lex Fridman Podcast, right? You’re putting this stuff together and building this internal model over several seconds. Which is basically we filter that out when we look at electrical activity in the brain because we’re interested in this millisecond scale, it’s almost massive amounts of information, right? So the way I see it is every technique gives you a little limited window into what’s going on.
fMRI has huge problems, people lie down in the scanner. There’s parts of the brain where… I will show you in some of these images where you’ll see kind of gaping holes because you can’t keep the magnetic field stable in those spots. You’ll see parts where it’s like there’s a vein, and so it just produces big increase and decrease in signal or respiration that causes these changes. There’s lots of artifacts and stuff like that. Every technique has its limits. If I’m lying down in an MRI scanner, I’m lying down. I’m not interacting with you in the same way that I would in the real world. But at the same time, I’m getting data that I might not be able to get otherwise. And so different techniques give you different kinds of advantages.
If I give you outside of the scanner, you’re done with the scanner, I just scan you while you’re watching a movie, just watch it. You come out, I give you a test of memory for stories. What happens is you find this incredible correlation between the activity in the hippocampus at these singular points in time, these event boundaries. And your ability to just remember a story outside of the scanner later on. So it’s marking this ability to encode memories, just these little snippets of neural activity. So I think that’s a big one. There’s all sorts of work in animal models that I can get into. Sleep, I think there’s so much interesting stuff that’s being discovered in sleep right now.
Being able to just record from large populations of cells and then be able to relate that… [inaudible 01:32:03], I think the coolest thing gets back to this QR code thing, because what we can do now is I can take fMRI data while you’re watching a movie. Let’s do better than that. Let me get fMRI data while you use a joystick to move around in virtual reality. So you’re in the metaverse, whatever. But it’s kind of a crappy metaverse because there’s only so much metaversing you can do in an MRI scanner. So you’re doing this crappy metaversing. So now, I can take a rat, record from its hippocampus and prefrontal cortex and all these areas with these really new electrodes that get massive amounts of data. And have it move around on a trackball in virtual reality in the same metaverse that I did, and record that rat’s activity.
I can get a person with epilepsy who we have electrodes in their brain anyway, to try to figure out where the seizures are coming from. And if it’s a healthy part of the brain, record from that person, right? And I can get a computational model. And one of the brand new members in my lab, Tyler Brown is just doing some great stuff. He relates computer vision models and looks at the weaknesses of computer vision models and relates to what the brain does well.
So, there’s a lot of conservation of some of these neural circuits across evolution in mammals, for instance. And then some people would even say that there’s genetic mechanisms for learning that are conserved, even going back far, far before. But let’s go back to the mice in humans question.
There’s a lot of differences. So, for one thing, the sensory information is very different. Mice and rats explore the world largely through smelling, olfaction, but they also have vision that’s kind of designed to catch death from above. So, it’s like a very big view of the world. And we move our eyes around in a way that focuses on particular spots in space where you get very high resolution from a very limited set of spots in space. So, that makes us very different in that way.
We also have all these other structures as social animals that allow us to respond differently. There’s language, there’s… you name it, there’s obviously gobs of differences. Humans aren’t just giant rats. There’s much more complexity to us. Timescales are very important. So, primate brains and human brains are especially good at integrating and holding on to information across longer and longer periods of time.
Also, finally, it’s like our history of training data, so to speak, is very, very different than… Human’s world is very different than a wild mouse’s world. And a lab mouse’s world is extraordinarily impoverished relative to an adult human. Yeah.
How does that happen and how do you regulate those interactions, these dynamic interactions? We’re still figuring that out. But that’s going to be coming largely from model systems that are easier to understand. You can do manipulations, like drug manipulations, to manipulate circuits, and use viruses and so forth, and lasers to turn on circuits that you just can’t do in humans.
So, I think there’s a lot that can be learned from mice. There’s a lot that can be learned from non-human primates. And then there’s a lot that you need to learn from humans. And I think unfortunately, some of the people in the National Institutes of Health think you can learn everything from the mouse. It’s like, “Why study memory in humans when I could study learning in a mouse?” And just like, “Oh my God, I’m going to get my funding from somewhere else.”
But deja vu is the sense that it can be almost disturbing intense sense of familiarity. So, there was a researcher named Wilder Penfield… Actually, this goes back even earlier to some of the earliest, like Hughlings Jackson was this neurologist who did a lot of the early characterizations of epilepsy. And one of the things he notices in epilepsy patients, some group of them right before they would get a seizure, they would have this intense sense of deja vu. So, it’s this artificial sense of familiarity, it’s a sense of having a memory that’s not there.
What was happening was there was electrical activity in certain parts of these brains, so the guy Penfield, later on when he was trying to look for how do we map out the brain to figure out which parts we want to remove and which parts don’t we, he would stimulate parts of the temporal lobes of the brain and find you could elicit the sense of deja vu. Sometimes you’d actually get a memory that a person would re-experience just from electrically stimulating some parts. Sometimes they just have this intense feeling of being somewhere before.
And so, one theory which I really like is that in higher order areas of the brain, they’re integrating from many, many different sources of input. What happens is that they’re tuning themselves up every time you process a similar input. And so that allows you to just get this kind of affluent sense that, “I’m very familiar…” You’re very familiar with this place. And so just being here, you’re not going to be moving your eyes all over the place because you kind of have an idea of where everything is. And that fluency gives you a sense of, “I’m here.”
Now, I wake up in my hotel room and I have this very unfamiliar sense of where I am. But there’s a great set of studies done by Anne Cleary at Colorado State where she created these virtual reality environments. And we’ll go back to the metaverse. Imagine you go through a virtual museum, and then she would put people in virtual reality and have them go through a virtual arcade. But the map of the two places was exactly the same. She just put different skins on them. So, one looks different than the other, but they’ve got same landmarks, and the same places, same objects, same everything, but carpeting, colors, theme, everything’s different.
People will often not have any conscious idea that the two are the same, but they could report this very intense sense of deja vu. So, it’s like a partial match that’s eliciting this kind of a sense of familiarity. And that’s why in patients who have epilepsy, that affects memory, you get this artificial sense of familiarity that happens.
And so we think that… And again, this is just one theory amongst many, but we think that we get a little bit of that feeling, it’s not enough to necessarily give you deja vu, even for very mundane things. So, it’s like if I tell you the word rutabaga, your brain’s going to work a little bit harder to catch it than if I give you word like apple. That’s because you hear apple a lot. So, your brain’s very tuned up to process it efficiently, but rutabaga takes a little bit longer and more intense. And you can actually see a difference in brain activity in areas in the temporal lobe when you hear a word just based on how frequent it is in the English language.
So, I’m a scientist and I collect data, but I use theories to make sense of that data. And so, a memory is kind of a mix of all these things. Where memories can go off the deep end and become what we would call conventionally as false memories are sometimes little distortions where we filled in the blanks, the gaps in our memory, based on things that we know, but don’t actually correspond to what happened.
So, if I were to tell you that a story about this person who’s worried that they have cancer or something like that, and then they see a doctor and the doctor says, “Well, things are very much like you would’ve expected or what you were afraid of,” or something. When people remember that, they’ll often remember, “Well, the doctor told the patient that he had cancer.” Even if that wasn’t in the story because they’re infusing meaning into that story. So, that’s a minor distortion. But what happens is that sometimes things can really get out of hand where people have trouble telling the difference between things that they’ve imagined versus things that happen. But also, as I told you, the act of remembering can change the memory. And so what happens then is you can actually be exposed to some misinformation. And so Elizabeth Loftus was a real pioneer in this work, and there’s lots of other work that’s been done since.
But basically, it’s like if you remember some event, and then I tell you something about the event, later on, when you remember the event, you might remember some original information from the event as well as some information about what I told you. And sometimes, if you’re not able to tell the difference, that information that I told you gets mixed into the story that you had originally. So, now I give you some more misinformation or you’re exposed to some more information somewhere else, and eventually your memory becomes totally detached from what happened. And so sometimes you can have cases where people… This is very rare, but you can do it in lab too, or a significant… not everybody, but a chunk of people will fall for this, where you can give people misinformation about an event that never took place. And as they keep trying to remember that event more and more, what happens is they start to imagine, they start to pull up things from other experiences they’ve had, and eventually they can stitch together a vivid memory of something that never happened because they’re not remembering an event that happened. They’re remembering the act of trying to remember what happened, and basically putting it together into the wrong story.
Because once you and I share a memory, I tell you about something I’ve experienced and you tell me about your experience at the same event, it’s no longer your memory or my memory, it’s our memory. And so now the misinformation spreads. And the more you trust someone or the more powerful that person is, the more of a voice they have in shaping that narrative.
And there’s all sorts of interesting ways in which misinformation can happen. There’s a great example of when John McCain and George Bush Jr. were in a primary, and there were these polls where they would do these, I guess they were not robocalls, but real calls where they would poll voters, but they actually inserted some misinformation about McCain’s beliefs on taxation, I think, or maybe it was something about illegitimate children or… I don’t really remember. But they included misinformation in the question that they asked, “How do you feel about the fact that he wants to do this?” Or something.
And so people would end up becoming convinced he had these policy things or these personal things that were not true, just based on the polls that were being used. So, it was a case where, interestingly enough, the people who were using misinformation were actually ahead of the curve relative to the scientists who were trying to study these effects in memory.
If you just look throughout the 20th century, some of the dictatorships with Nazi Germany, with the Soviet Union, effective propaganda machines can rewrite our conceptions of history, how we remember our own culture, our upbringing, all this kind of stuff. And you could do quite a lot of damage in this way. And then there’s probably some kind of social contagion happening there. Certain ideas that, maybe initiated by the propaganda machine, can spread faster than others.
You could see that in modern day, certain conspiracy theories, there’s just something about them that they are really effective at spreading. There’s something sexy about them to people to where something about the human mind eats it up and then uses that to construct memories as if they almost were there to witness whatever the content of the conspiracy theory is. It’s fascinating. Because you feel like you remember a thing, I feel like there’s a certainty. It emboldens you to say stuff. It’s not just you believe in ideas, true or not, it’s at the core of your being that you feel like you were there to watch the thing happen.
And you brought up this weaponization of history, and it really speaks to, I think, one of the parts of memory, which is that if you have a belief, you will find, and you have a goal in mind, you’ll find stuff in memory that aligns with it, and you won’t see the parts in memory that don’t. So, a lot of the stories we put together are based on our perspectives.
And so let’s just zoom out for the moment from misinformation to take something even more fascinating, but not as scary. I was reading Thanh Viet Nguyen, but he wrote a book about the collective memory of the Vietnam War. He is a Vietnamese immigrant who was flown out after the war was over. And so he went back to his family to get their stories about the war, and they called it the American War, not the Vietnam War. And that just kind of blew my mind, having grown up in the US and having always heard about it as the Vietnam War. But of course they call it the American War, because that’s what happened. America came in. And that’s based on their perspective, which is a very valid perspective. And so that just gives you this idea of the way we put together these narratives based on our perspectives. And I think the opportunities that we can have in memory is if we bring groups together from different perspectives and we allow them to talk to each other and we allow ourselves to listen.
I mean, right now you’ll hear a lot of just jammering, people going, “Blah, blah, blah,” about free speech, but they just want to listen to themselves. I mean, it’s like, let’s face it, the old days before people were supposedly woke, they were trying to ban 2 Live Crew. Just think about Lenny Bruce got canceled for cursing. Jesus Christ. It’s like this is nothing new. People don’t like to hear things that disagree with them.
But if you’re in a… I mean, you can see two situations in groups with memory. One situation is you have people who are very dominant, who just take over the conversation. And basically what happens is the group remembers less from the experience and they remember more of what the dominant narrator says. Now, if you have a diverse group of people, and I don’t mean diverse in necessarily the human resource sense of the word, I mean diverse in any way you want to take it, but diverse in every way, hopefully. And you give everyone a chance to speak and everyone’s being appreciated for their unique contribution, you get more accurate memories and you get more information from it.
Even two people who come from very similar backgrounds, if you can appreciate the unique contributions that each one has, you can do a better job of generating information from memory. And that’s a way to inoculate ourselves, I believe, from misinformation in the modern world. But like everything else, it requires a certain tolerance for discomfort. And I think when we don’t have much time, and I think when we’re stressed out and when we are just tired, it’s very hard to tolerate discomfort.
I mean, look at you. You’ve got this keyboard that’s got these dome shaped things, and you’ve adapted to that to communicate. That’s not the technology adapting to you, that’s you adapting to the technology. And I think one of the things I learned when Google started to introduce autocomplete in emails, I started to use it. And about a third of the time I was like, “This isn’t what I want to say.” A third of the time, I’d be like, “This is exactly what I wanted to say.” And a third of the time I was saying, “Well, this is good enough. I’ll just go with it.”
And so what happens is it’s not that the technology necessarily is doing anything so bad, as much as it’s just going to constrain my language because I’m just doing suggested to me. And so this is why I say, kind of like my mantra for some of what I’ve learned about everything in memory, is to diversify your training data, basically, because otherwise you’re going to… So, humans have this capability to be so much more creative than anything generative AI will put together, at least right now, who knows where this goes? But it can also go the opposite direction where people could become much, much less creative, if they just become more and more resistant to discomfort and resistant to exposing themselves to novelty, to cognitive dissonance, and so forth.
So, what you’re asking is a deeper sort of biological question, do we want to be… Werner Herzog and the movie Happy People: Life in the Taiga, do we want to be busy 100% of our time hunting, gathering, surviving, worried about the next day? Maybe that constant struggle ultimately creates a more fulfilling life. I don’t know. But I do know this modern society allows us to, when we’re sick, to find medicine, to find cures, when we’re hungry, to get food, much more than we did even a hundred years ago. And there’s many more activities that you could perform, all creative, all these kinds of stuff that enables the flourishing of humans at the individual level.
Whether that leads to happiness, I mean, that’s a very deep philosophical question. Maybe struggle, deep struggle is necessary for happiness.
So, it’s like you get a paycheck every month from MIT or whatever, and you probably don’t even get excited about it when you get the paycheck. But if they cut your salary, you’re going to be pissed. And if they increase your salary, “Oh good, I got a bonus.” And that adaptation and that ability that basically you learn to expect these things, I think, is a major source of… I guess it’s a major way in which we’re kind of more, in my opinion, wired to strive and not be happy, to be in a state of wanting.
And so people talk about dopamine, for instance, being this pleasure chemical. And there’s a lot of compelling research to suggest it’s not about pleasure at all. It’s about the discomfort that energizes you to get things, to seek a reward. And so you could give an animal that’s been deprived of dopamine a reward and, “Oh yeah, I enjoy it. It’s pretty good.” But they’re not going to do anything to get it.
And just one of the weird things in our research is I got into curiosity from a postdoc in my lab, Matthias Gruber, and one of the things that we found is when we gave people a question, like a trivia question that they wanted the answer to, that question, the more curious people were about the answer, the more activity in these dopamine-related circuits in the brain, we would see. And again, that was not driven by the answer per se, but by the question.
So, it was not about getting the information, it was about the drive to seek the information. But it depends on how you take that. If you get this uncomfortable gap between what you know and what you want to know, you could either use that to motivate you and energize you, or you could use it to say, “I don’t want to hear about this. This disagrees with my beliefs. I’m going to go back to my echo chamber.”
And from what I understand, the research actually shows that they just produce what people want to hear, not necessarily the information that is being looked for. And the reason is that… I mean, there’s different reasons. One is people just get tired of being tortured and just say whatever. But another part of it is that you create a very interesting set of conditions where there’s an authority figure telling you something that, “You did this, we know you did this. We have witnesses saying you did this.”
So, now you start to question yourself. Then they put you under stress. Maybe they’re not feeding you, maybe they’re making you be cold or exposing you to music that you can’t stand or something, whatever it is, right? It’s like they’re creating this physical stress. And so stress starts to down-regulate the prefrontal cortex. You’re not necessarily as good at monitoring the accuracy of stuff. Then they start to get nice to you and they say, “Imagine, okay, I know you don’t remember this, but maybe we can walk you through how it could have happened.” And they feed you the information.
And so you’re in this weakened mental state, and you’re being encouraged to imagine things by people who give you a plausible scenario. And at some point, certain people can be very coaxed into creating a memory for something that never happened. And there’s actually some pretty convincing cases out there where you don’t know exactly the truth.
There’s a sheriff, for instance, who came to believe that he had a false memory… I mean, that he had a memory of doing sexual abuse based on essentially, I think it was… I’m not going to tell the story because I don’t remember it well enough to necessarily accurately give it to you, but people could look this stuff up. There are definitely stories out there like this where people confess to crimes that they just didn’t do, and-
There’s really so many reasons though, but I’ve had this. My first pet I had, we got it for a wedding present. It was a cat. Got it after, but it died of FIP when it was four years old. I just would see her everywhere around the house. We got another cat, then we got a dog. Dog eventually died of cancer, and the cat just died recently. So we got a new dog because I kept seeing the dog around and I was just so heartbroken about this, but I still remember the pets that died. It just comes back to you. I mean, it’s part of this. I think there’s also something about attachment that’s just so crucial that drives again, these things that we want to remember and that gives us that longing sometimes. Sometimes it’s also not just about the heartbreak, but about the positive aspects of it.
The loss comes from not only the fact that the relationship is over, but you had all of these good things before that you can now see in a new light. Part of one of the things that I found from my clinical background that really I think gave me a different perspective on memory is so much of the therapy process was guided towards reframing and getting people to look at the past in a different way, not by imposing changing people’s memories or not by imposing an interpretation, but just offering a different perspective and maybe one that’s kind of more optimized towards learning and an appreciation maybe, or gratitude, whatever it is that gives you a way of taking…
I think you said it in the beginning, right? Where you can have this kind of dark experiences and you can use it as training data to grow in new ways, but it’s hard.
It sucks that you don’t have a thing, but when you don’t have a thing, it’s a good moment to viscerally experience the memories of something that you now appreciate even more.
In some way, the idea of Buddhism is like staying out of the world of memory and staying in the moment. They talked about how do you renounce attachments to the people that you love? They’re just saying, “Well, I appreciate that I have this moment with them and knowing that they will die makes me appreciate this moment that much more.” You said something similar in your daily routine that you think about things this way, right?
It is kind of like why when you’re older, the difference between somebody who’s 50 and 45 doesn’t seem as big as the difference between 10 and five or something. When you’re 10 years old, everything seems like it’s a long period of time. Here’s the point is that… One of the interesting things that I found when I was working on the book actually was during the pandemic, I just decided to ask people in my class when we were doing the remote instruction. One of the things I did was I would pull people. I just asked people, “Do you feel like the days are moving by slower or faster or about the same?”
Almost everyone in the class said that the days were moving by slower. Then I would say, “Okay, so do you feel like the weeks are passing by slower, faster, or the same?” The majority of them said that the weeks were passing by faster. According to the laws of physics, I don’t think that makes any sense, but according to memory, it did because what happened was people were doing the same thing over and over in the same context. Without that change in context, their feeling was that they were in one long monotonous event.
Then at the end of the week, you look back at that week and you say, “Well, what happened? I have no memories of what happened,” so the week just went by without even my noticing it. That week went by during the same amount of time as an eventful week where you might’ve been going out hanging out with friends on vacation or whatever. It’s just that nothing happened because you’re doing the same thing over and over. I feel like memory really shapes our sense of time, but it does so in part because context is so important for memory.
By the way, I’m the same way, but it’s like it really is the source of a lot of darkness for me. When you can look back at, let’s say you hear a song that you used to play before you would go do a sports thing or something like that, you might not think of yourself as an athlete, but once you mentally time travel to that particular thing, you open up this little compartment of yourself that wasn’t there before that didn’t seem accessible before. Dan Schacter’s lab did this really cool study where they would ask people to either remember doing something altruistic or imagine doing something altruistic, and that act made them more likely to want to do things for other people.
That act of mental time travel can change who you are in the present. We tend to think of, this goes back to that illusion of stability, and we tend to think of memory in this very deterministic way that I am who I am because I have this past, but we have a very multi-faceted past and can access different parts of it and change in the moment based on whatever part we want to reach for.
It’s like America used to be so great, and now it sucks. My life used to be so great when I was a kid and now it’s not. You’re selectively remembering the things that… I mean, we don’t realize how selective our remembering self is. I lived through the 70s. It sucked. Partly it sucked more for me, but I would say that even otherwise, it’s like there’s all sorts of problems going on, gas lines, people were worried about Russia, nuclear war, blah, blah, blah. It’s just this idea that people have about the past can be very useful if it brings you happiness in the present, but if it narrows your worldview in the present, you’re not aware of those biases that you have, it can be toxic either at a personal level or at a collective level.
One of my colleagues, Sergey Stavisky is just a genius in this area, and they’re working on it. I think speech prosthetics like they’re incorporating, decoding techniques with AI and movement prosthetics. This is just the rate of progress is just enormous. Part of the technology is having good enough data and understanding which data to use and what to do with it. Then the other part of it then is the algorithms for decoding it and so forth. I think part of that has really resulted in some real breakthroughs in neuroscience as a result. There’s lots of new technologies like Neuropixels for instance, that allow you to harvest activity from many, many neurons from a single electrode.
I know Neuralink has some technologies that are also along these lines, but again, because they do their own stuff, the scientific community doesn’t see it. I think BCI is much, much bigger than Neuralink and there’s just so much innovation happening. I think the interesting question which we may be getting into is, I was talking to Sergey a while ago about a lot of language is not just what we hear and what we speak, but also our intentions and our internal models. And so, are you really going to be able to restore language without dealing with that part of it?
He brought up a really interesting question, which is the ethics of reading out people’s intentions and understanding of the world as opposed to the more concrete parts of hearing and producing movements.
Is it ethical to reveal that full shebang, the full context of what’s going on in our brain? That’s really interesting. That’s really interesting. Our thoughts, is it ethical for anyone to have access to our thoughts? Because right now the resolution is so low that we’re okay with it, even doing studies and all this kind of stuff. If neuroscience has a few breakthroughs to where you can start to map out the QR codes for different thoughts, for different kinds of thoughts, maybe political thoughts, the McCarthyism, what if I’m getting a lot of them communist thoughts, or however we want to categorize or label it? That’s interesting.
That’s really interesting. I think ultimately this always… The more transparency there is about the human mind, the better it is. There could be always intermediate battles with how much control does a centralized entity have, like a government and so on. What is the regulation? What are the rules? What’s legal and illegal? If you talk about the police, whose job is to track down criminals and so on, and you look at all the history, how the police could abuse its power to control the citizenry, all that kind of stuff. People are always paranoid and rightfully so. It’s fascinating. It’s really fascinating.
We talk about freedom of speech, freedom of thought, which is also a very important liberty at the core of this country and probably humanity. It starts to get awfully tricky when you start to be able to collect those thoughts. What I wanted to actually ask you is do you think for fun and for practical purposes, we would be able to modify memories? How far away we are from understanding the different parts of the brains, everything we’ve been talking about, in order to figure out how can we adjust this memory at the crude level from unpleasant to pleasant?
You talked about we can remember the mall and the location, the people. Can we keep the people and change the place? This kind of stuff, how difficult is that?
Right now, I think as an outsider looking at the data, I think it’s mixed results. Part of it is, and this speaks to the more complex issue, is that you need somebody to actually fully recall that traumatic memory in the first place. In order to actually modify it, then what is the memory? That is the key part of the problem. If we go back to reading people’s thoughts, what is the thought? People can sometimes look at us like behaviorists and go, “Well, the memory is like I’ve given you A and you produce B,” but I think that’s a very bankrupt concept about memory. I think it’s much more complicated than that.
One of the things that when we started studying naturalistic memory, like memory from movies, that was so hard was we had to change the way we did the studies. If I show you a movie and I watched the same movie and you recall everything that happened, and I recall everything that happened, we might take a different amount of time to do it. We might use different words. And yet, to an outside observer, we might’ve recalled the same thing. It’s not about the words necessarily, and it’s not about how long we spent or whatever.
There’s something deeper that is there that’s this idea, but it’s like, how do you understand that thought? I encounter a lot of concrete thinking that it’s like if I show a model, like the visual information that a person sees when they drive, I can basically reverse engineer driving. Well, that’s not really how it works. I once saw somebody talking in this discussion between neuroscientists and AI people, and he was saying that the problem with self-driving cars that they had in cities as opposed to highways was that the car was okay at doing the things it’s supposed to, but when there were pedestrians around, it couldn’t predict the intentions of people.
And so, that unpredictability of people was the problem that they were having in the self-driving car design. It didn’t have a good enough internal model of what the people were, what they were doing, what they wanted. What do you think about that?
There’s a history to that intersection, like jaywalking, certain intersections allow jaywalking a lot more because what happens is we’re leaders and followers, so there’s a regular, let’s say, and they get off the subway and they start crossing on a red light, and they do this every single day. Then there’s people that don’t show up to that intersection often, and they’re looking for cues of how we’re supposed to behave here. If a few people start to jaywalk and cross on a red light, they will also. They will follow. There’s just a dynamic to that intersection. There’s a spirit to it.
If you look at Boston versus New York versus a rural town versus even Boston, San Francisco or here in Austin, there’s different personalities city-wide, but there’s different personalities area-wise, region-wise, and there’s different personalities at different intersections. It’s just fascinating. For a car to be able to determine that, it’s tricky. Now, what machine learning systems are able to do well is collect a huge amount of data. For us, it’s tricky because we get to understand the world with very limited information and make decisions grounded in this big foundation model that we’ve built of understanding how humans work. AI could literally, in the context of driving, this is where I’ve often been really torn in both directions. If you just collect a huge amount of data, all of that information, and then compress it into a representation of how humans cross streets, it’s probably all there. In the same way that you have a Noam Chomsky who says, “No, no, no, AI can’t talk, can’t write convincing language without understanding language.” More and more you see large language models without “understanding” can generate very convincing language.
I think what the process of compression from a huge amount of data compressing into a representation is doing is in fact understanding deeply. In order to be able to generate one letter at a time, one word at a time, you have to understand the cruelty of Nazi Germany and the beauty of sending humans to space. You have to understand all of that in order to generate, “I’m going to the kitchen to get an apple,” and do that grammatically correctly. You have to have a world model that includes all of human behavior.
For the case of driving, I think it could be quite effective. One of the things that’s currently missing, even though OpenAI just recently announced adding memory, and I did want to ask you how important it is, how difficult is it to add some of the memory mechanisms that you’ve seen in humans to AI systems?
What the human brain is doing is we have this kind of actually a fairly dumb system, which just says, “This happened once at this point in time,” which we call episodic memory, so to speak. Then we have this knowledge that we’ve accumulated from our experiences of semantic memory. Now when we encounter a situation that’s surprising and violates all our previous expectations, what happens is that now we can form an episodic-
These are the hard questions. When do you use episodic memory? When do you just throw it away? These are the hard questions we’re still trying to figure out in people. Then you start to think about all these mechanisms that we have in the brain for figuring out some of these things. And it’s not just one, but it’s many of them that are interacting with each other. And then you just take not only the episodic and the semantic, but then you start to take the motivational survival things, right? It’s just like the fight-or-flight responses that we associate with particular things, or the reward motivation that we associate with certain things, so forth.
And those things are absent from AI. I frankly don’t know if we want it. I don’t necessarily want a self-motivated LLM, right? It’s like, and then there’s the problem of how do you even build the motivations that should guide a proper reinforcement learning kind of thing, for instance. So a friend of mine, Sam Gershman, I might be missing the quote exactly, but he basically said, “If I wanted to train a typical AI model to make me as much money as possible, first thing I might do is sell my house.” So it’s not even just about having one goal or one objective, but just having all these competing goals and objectives, and then things start to get really complicated.
And then, he found those were the exact ones where these humans with particular damage to this area called the perirhinal cortex, that was where they were struggling. So somehow this brain area was important for being able to do these things that were adversarial to these computer vision models. So then he found that it only happened if people had enough time, they could make those discriminations, but without enough time if they just get a glance, they’re just like the computer vision models. So then what he started to say was, “Well, maybe let’s look at people’s eyes.”
So computer vision model sees every pixel all at once, and we don’t, we never see every pixel all at once. Even if I’m looking at a screen with pixels, I’m not seeing every pixel at once. I’m grabbing little points on the screen by moving my eyes around, and getting a very high resolution picture of what I’m focusing on, and kind of a lower resolution information about everything else. But I’m not necessarily choosing, but I’m directing that exploration, and allowing people to move their eyes and integrate that information gave them something that the computer vision models weren’t able to do. So somehow integrating information across time and getting less information at each step gave you more out of the process.
Attention is at the core of it, it’s probably at the core of memory too. There’s so much sensory information. There’s so much going on, there’s so much going on. To filter it down to almost nothing and just keep those parts, and to keep those parts, and then whenever there’s an error to adjust the model, such that you can allocate attention even better to new things that would resolve, maybe maximize the chance of confirming the model, or disconfirming the model that you have, and adjusting it since then. Yeah, attention is a weird one. I was always fascinated. I mean, I got a chance to study peripheral vision for a bit and indirectly study attention through that. And it’s just fascinating how good humans are looking around and gathering information.
It’s like, well, the machines make different kinds of mistakes than the people do, and I will never be convinced unless we’ve replicated human. I don’t even like the term intelligence. I think it is a stupid concept, but I don’t think we’ve replicated human intelligence, unless I know that the simulator is making exactly the same kinds of mistakes that people do, because people make characteristic mistakes. They have characteristic biases, they have characteristic heuristics that we use, and those have yet to see evidence that ChatGPT will do that.
So then my parents said, okay, well, they got me on a diet free of artificial colors and flavors, because that was the thing that people talked about back then. I’m interested this topic, because I’ve come to appreciate now that I have many of the characteristics, if not full-blown, it’s like I’m definitely, timeline is a rejection since you name it, they talk about it. It’s like impulsive behavior. I can tell you about all sorts of fights I’ve gotten into in the past, just you name it. But yeah, so ADHD is fascinating though, because right now we’re seeing more and more diagnosis of it, and I don’t know what to say about that. I don’t know how much of that is based on inappropriate expectations, especially for children and how much of that is based on true maladaptive kinds of tendencies.
But what we do know is this, is that ADHD is associated with differences in prefrontal function, so that attention can be both more, you’re more distractible, you have harder time focusing your attention on what’s relevant, and so you shift too easily. But then, once you get on something that you’re interested in, you can get stuck. And so, the attention is this beautiful balance of being able to focus when you need to focus, and shift when you need to shift. And so it’s that flexibility plus stability again, and that’s balance seems to be disrupted in ADHD. And so, as a result, memory tends to be poor in ADHD, but it’s not necessarily because there’s a traditional memory problem, but it’s more because of this attentional issue. And people with ADHD often will have great memory for the things that they’re interested in, and just no memory for the things that they’re not interested in.
Let me get back to it. And I go back to something else. And so, I’ve just got fragmentary memories of everything. So what I’m trying to do is set aside a timer. This is my email time, this is my writing time, this is my goofing off time. And so, blocking these things off, you give yourself the goofing off time. Sometimes I do that and sometimes I have to be flexible, and go like, okay, I’m definitely not focusing. I’m going to give myself the down time, and it’s an investment. It’s not like wasting time. It’s an investment in my attention later on.
And then, what happens is I don’t remember anything from that day. It just kind of vanished, because what happens, I’m creating all these artificial event boundaries. I’m losing all this executive function every time I switch, I’m getting a few seconds slower and I’m catching up mentally to what’s happening. And so, instead of being in a model where you’re meaningfully integrating everything and predicting and generating this kind of rich model, I’m just catching up. And so yeah, there’s great research by Melina Uncapher and Anthony Wagner on multitasking, that people can look up that talks about just how bad it is for memory, and it’s becoming worse and worse of a problem.
And so, then you started seeing all this stuff. And then, I got into metal was kind of my early genre, and I always reacted to just things that were loud and had a beat. I mean, ADHD, right? It’s like everything from Sergeant Pepper by the Beatles to Led Zeppelin II. My dad had, both my parents had both those albums, so I listened to them a lot. And then, the Police, Ghost in the Machine. But then I got into metal Def Leppard, and AC/DC, Metallica. Went way down the rabbit hole of speed metal. And that time was kind of like, oh, why don’t I play guitar? I can do this. And I had friends who were doing that, and I just never got it. I took lessons and stuff like that, but it was different, because when I was doing trumpet, I was reading sheet music and I was learning by looking, there’s a thing called Tablature, where it’s like you see a drawing of the fretboard with numbers, and that’s where you’re supposed to put your… It’s kind of paint by numbers. And so, I learned it in a completely different way, but I was still terrible at it and I didn’t get it. It’s actually taken me a long time to understand exactly what the issue was, but it wasn’t until I really got into punk and I saw bands. I saw Sonic Youth, I remember especially, and it just blew my mind, because they violated the rules of what I thought music was supposed to be. I was like, this doesn’t sound right. These are not power chords, and this isn’t just have a shouty verse, and then a chorus part. It’s not going back. This is just weird. And then it occurred to me, you don’t have to write music the way people tell you it’s supposed to sound. That just opened up everything for me, and I was playing in a band. I was struggling with writing music, because I would try to write whatever was popular at the time, or whatever sounded other bands that I was listening to. And somehow I kind of morphed into just grabbing a guitar and just doing stuff. And I realized a part of my problem with doing music before was, I didn’t enjoy trying to play stuff that other people played. I just enjoyed music just dripping out of me and spilling out, and just doing stuff. And so, then I started to say, what if I don’t play a chord? What if I just play notes that shouldn’t go together and just mess around with stuff? Then I said, well, what if I don’t do four beats? Go na, na, na na, one, two, three four, one two, three four, one, two, three, four.
What if I go one, two, three, four, five, one, two, three, four, five? And started messing around with time signatures. Then I was playing in this band with a great musician, Brent Ritzel, who was in this band with me, and he taught me about arranging songs. And it was like, what if we take this part and instead of make it go back and forth, we make it a circle, or what if we make it a straight line, or zigzag, just make it nonlinear in these interesting ways? And then next thing you know, it’s the whole world sort of opens up as, and then what I started to realize, especially so you could appreciate this as a musician, I think. So time signatures. So we are so brainwashed to think in four-four, right? Every rock song you could think of almost is in four-four. I know you’re a Floyd fan, So think of Money by Pink Floyd, right?
Thank you for listening. I hope to see you next time.

Introduction
Charan Ranganath
The act of remembering can change the memory. If you remember some event and then I tell you something about the event, later on when you remember the event, you might remember some original information from the event as well as some information about what I told you. And sometimes if you’re not able to tell the difference, that information that I told you gets mixed into the story that you had originally. So now I give you some more misinformation or you’re exposed to some more information somewhere else and eventually your memory becomes totally detached from what happened.

The following is a conversation with Charan Ranganath, a psychologist and neuroscientist at UC Davis specializing in human memory. He’s the author of, Why We Remember. Unlocking Memory’s Power To Hold On To What Matters. This is the Lex Fridman podcast. To support it, please check out our sponsors in the description. And now, dear friends, here’s Charan Ranganath. Danny Kahneman describes the experiencing self and the remembering self and that happiness and satisfaction you gained from the outcomes of your decisions do not come from what you’ve experienced, but rather from what you remember of the experience. So can you speak to this interesting difference that you write about in your book of the experiencing self and the remembering self?

Experiencing self vs remembering self
Charan Ranganath
Danny really impacted me. I was an undergrad at Berkeley and I got to take a class from him long before he won the Nobel Prize or anything and it was just a mind-blowing class. But this idea of the remembering self and the experiencing self, I got into it because it’s so much about memory even though he doesn’t study memory. So we’re right now having this experience, right? And people can watch it presumably on YouTube or listen to it on audio, but if you’re talking to somebody else, you could probably describe this whole thing in 10 minutes, but that’s going to miss a lot of what actually happened. And so the idea there is that the way we remember things is not the replay of the experience, it’s something totally different.

And so the idea there is that the way we remember things is not the replay of the experience, it’s something totally different.
And it tends to be biased by the beginning and the end, and he talks about the peaks, but there’s also the best parts, the worst parts, etc. And those are the things that we remember. And so when we make decisions, we usually consult memory and we feel like our memory is a record of what we’ve experienced, but it’s not. It’s this kind of very biased sample, but it’s biased in an interesting and I think biologically relevant way.
Lex Fridman
So in the way we construct a narrative about our past, you say that it gives us an illusion of stability. Can you explain that?
So in the way we construct a narrative about our past, you say that it gives us an illusion of stability. Can you explain that?
Charan Ranganath
Basically I think that a lot of learning in the brain is driven towards being able to make sense. I mean really memory is all about the present and the future. The past is done. So biologically speaking, it’s not important unless there’s something from the past that’s useful. And so what our brains are really optimized for is to learn about the stuff from the past that’s going to be most useful and understanding the present and predicting the future. And so cause-effect relationships for instance, that’s a big one. Now my future is completely unpredictable in the sense that you could in the next 10 minutes pull a knife on me and slit my throat.

I was planning on it.

Charan Ranganath
Exactly. But having seen some of your work and just generally my expectations about life, I’m not expecting that. I have a certainty that everything’s going to be fine and we’re going to have a great time talking today, but we’re often right. It’s like, okay, so I go to see a band on stage, I know they’re going to make me wait, the show’s going to start late and then they come on. There’s a very good chance there’s going to be an encore. I have a memory, so to speak for that event before I’ve even walked into the show. There’s going to be people holding up their camera phones to try to take videos of it now because this is kind of the world we live in. So that’s like everyday fortune-telling that we do though.

It’s not real, it’s imagined. And it’s amazing that we have this capability and that’s what memory is about. But it can also give us the illusion that we know everything that’s about to happen. And I think what’s valuable about that illusion is when it’s broken, it gives us the information. So I mean, I’m sure being in AI about information theory and the idea is the information is what you didn’t already have. And so those prediction errors that we make based on, we make a prediction based on memory and the errors are where the action is.
Lex Fridman
The error is where the learning happens.
The error is where the learning happens.
Charan Ranganath
Exactly. Exactly.
Exactly. Exactly.
Lex Fridman
Well, just to linger on Danny Kahneman and just this whole idea of experiencing self versus remembering self, I was hoping you can give a simple answer of how we should live life based on the fact that our memories could be a source of happiness or could be the primary source of happiness, that an event when experienced bears its fruits the most when it’s remembered over and over and over and over. And maybe there is some wisdom in the fact that we can control to some degree how we remember it, how we evolve our memory of it, such that it can maximize the long-term happiness of that repeated experience.

Can I be your opening act?

Charan Ranganath
Oh my God, no, I’m going to open for you, dude. Otherwise, it’s like everybody leaves after you’re done. Believe me, I did that in Columbus, Ohio once. It wasn’t fun. The opening acts drank our bar tab. We spent all this money going all the way there and there was only the… Everybody left after the opening acts were done and there was just that stoner dude with the dreadlocks hanging out. And then next thing you know, we blew our savings on getting a hotel room.

Charan Ranganath
One thing that I try to live by, especially nowadays and since I wrote the book, I’ve been thinking more and more about this is, how do I want to live a memorable life? I think if we go back to the pandemic, how many people have memories from that period, aside from the trauma of being locked up and seeing people die and all this stuff. I think it’s one of these things where we were stuck inside looking at screens all day, doing the same thing with the same people. And so I don’t remember much from that in terms of those good memories that you’re talking about. When I was growing up, my parents worked really hard for us and we went on some vacations, but not very often.

When I was growing up, my parents worked really hard for us and we went on some vacations, but not very often.
And I really try to do now vacations to interesting places as much as possible with my family because those are the things that you remember. So I really do think about what’s going to be something that’s memorable and then just do it even if it’s a pain in the ass because the experiencing self will suffer for that but the remembering self will be like, “Yes, I’m so glad I did that.”
Lex Fridman
Do things that are very unpleasant in the moment because those can be reframed and enjoyed for many years to come. That’s probably good advice. Or at least when you’re going through, it’s a good way to see the silver lining of it.

Charan Ranganath
Yeah, I mean I think it’s one of these things where if you have people who you’ve gone through since you said it, I’ll just, since you’ve gone through shit with someone-
Yeah, I mean I think it’s one of these things where if you have people who you’ve gone through since you said it, I’ll just, since you’ve gone through shit with someone-
Lex Fridman
Yeah.
Yeah.
Charan Ranganath
… and it’s a, that’s bonding experience often, I mean that can really bring you together. I like to say it’s like there’s no point in suffering unless you get a story out of it. So in the book I talk about the power of the way we communicate with others and how that shapes our memories. And so I had this near-death experience, at least that’s how I remember it, on this paddleboard where just everything that could have gone wrong did go wrong, almost. So many mistakes were made. And ended up at some point just basically away from my board, pinned in a current in this corner, not a super good swimmer, and my friend who came with me, Randy, who’s a computational neuroscientist, and he had just been pushed down past me so he couldn’t even see me.

And I’m just like, “If I die here, I mean no one’s around. It’s like you just die alone.” And so I just said, “Well, failure is not an option.” And eventually I got out of it and froze and got cut up and I mean the things that we were going through were just insane. But short version of this is my wife and my daughter and Randy’s wife, they gave us all sorts of hell about this because they were just ready to send out a search party. So they were giving me hell about it. And then I started to tell people in my lab about this and then friends and it just became a better and better story every time. And we actually had some photos of just the crazy things like this generator that was hanging over the water and we’re ducking under this zig of these metal gratings and I’m going flat and it was just nuts.
But it became a great story. And it was definitely, Randy and I were already tight, but that was a real bonding experience for us. And I learned from that that it’s like I don’t look back on that enough actually because I think we often, at least for me, I don’t necessarily have the confidence to think that things will work out, that I’ll be able to get through certain things. But my ability to actually get something done in that moment is better than I give myself credit for, I think. And that was the lesson of that story that I really took away.
Lex Fridman
Well, actually just for me, you’re making me realize now it’s not just those kinds of stories, but even things like periods of depression or really low points, to me at least it feels like a motivating thing that the darker it gets, the better the story will be if you emerge on the other side. That to me feels like a motivating thing. So maybe if people listening to this and they’re going through some shit, as we said, one thing that could be a source of light is that it’ll be a hell of a good story when it’s all over, when you emerge on the other side. Let me ask you about decisions. You already talked about it a little bit, but when we face the world and we’re making different decisions, how much does our memory come into play?

Is it the kind of narratives that we’ve constructed about the world that are used to make predictions that’s fundamentally part of the decision-making?
Charan Ranganath
Absolutely. Yeah. So let’s say after this, you and I decided we’re going to go for a beer. How do you choose where to go? You’re probably going to be like, “Oh yeah, this new bar opened up near me. I had a great time there. They had a great beer selection.” Or you might say, “Oh, we went to this place and it was totally crowded and they were playing this horrible EDM or whatever.” And so right there, valuable source of information. And then you have these things like where you do this counterfactual stuff, “Well, I did this previously.” But what if I had gone somewhere else and said, “Maybe I’ll go to this other place because I didn’t try it the previous time”? So there’s all that kind of reasoning that goes into it too.
Absolutely. Yeah. So let’s say after this, you and I decided we’re going to go for a beer. How do you choose where to go? You’re probably going to be like, “Oh yeah, this new bar opened up near me. I had a great time there. They had a great beer selection.” Or you might say, “Oh, we went to this place and it was totally crowded and they were playing this horrible EDM or whatever.” And so right there, valuable source of information. And then you have these things like where you do this counterfactual stuff, “Well, I did this previously.” But what if I had gone somewhere else and said, “Maybe I’ll go to this other place because I didn’t try it the previous time”? So there’s all that kind of reasoning that goes into it too.
I think even if you think about the big decisions in life. It’s like you and I were talking before we started recording about how I got into memory research and you got into AI and it’s like we all have these personal reasons that guide us in these particular directions. And some of it’s the environment and random factors in life, and some of it is memories of things that we want to overcome or things that we build on in a positive way. But either way, they define us.
Lex Fridman
And probably the earlier in life the memories happen, the more defining, the more defining power they have in terms of determining who we become.

I mean, I do feel like adolescence is much more important than I think people give credit for. I think that there is this kind of a sense the first three years of life is the most important part, but the teenage years are just so important for the brain. And so that’s where a lot of mental illness starts to emerge. Now we’re thinking of things like schizophrenia as a neurodevelopmental disorder because it just emerges during that period of adolescence and early adulthood. And I think the other part of it is is that I guess I was a little bit too firm in saying that memory determines who we are. It’s really the self is an evolving construct. I think we kind of underestimate that.

And when you’re a parent, you feel like every decision you make is consequential in forming this child and it plays a role, but so do the child’s peers. And so do… There’s so much, I mean that’s why I think the big part of education I think that’s so important is not the content you learn… I mean, think of how much dumb stuff we learned in school. But a lot of it is learning how to get along with people and learning who you are and how you function. And that can be terribly traumatizing even if you have perfect parents working on you.
Creating memories
Lex Fridman
Is there some insight into the human brain that explains why we don’t seem to remember anything from the first few years of life?
Is there some insight into the human brain that explains why we don’t seem to remember anything from the first few years of life?
Charan Ranganath
Yeah. Yeah. In fact, actually I was just talking to my really good friend and colleague, Simona Getty, who studies the neuroscience of child development and so we were talking about this. And so there are a bunch of reasons I would say. So one reason is is there’s an area of the brain called the hippocampus, which is very, very important for remembering events or episodic memory. And so the first two years of life, there’s a period called infantile amnesia. And then the next couple years of life after that, there’s a period called childhood amnesia. And the differences is is that basically in the lab and even during childhood and afterwards, children basically don’t have any episodic memories for those first two years.

And the differences is is that basically in the lab and even during childhood and afterwards, children basically don’t have any episodic memories for those first two years.
The next two years it’s very fragmentary and that’s why they call it childhood amnesia, so there’s some, but it’s not long. So one reason is is that the hippocampus is taking some time to develop, but another is the neocortex of the whole folded stuff of gray matter all around the hippocampus is developing so rapidly and changing. And a child’s knowledge of the world is just massively being built up, so I’m going to probably embarrass myself, but it’s like if you showed you trained a neural network and you give it the first couple of patterns or something like that, and then you bombard it with another years worth of data, try to get back those first couple of patterns. It’s like everything changes.
And so the brain is so plastic, the cortex is so plastic during that time, and we think that memories for events are very distributed across the brain. Imagine you’re trying to get back that pattern of activity that happened during this one moment, but the roads that you would take to get there have been completely rerouted. I think that’s my best explanation. The third explanation is a child’s sense of self takes a while to develop. And so their experience of learning might be more learning what happened as opposed to having this first-person experience of, “I remember. I was there.”
Lex Fridman
Well, I think somebody once said to me that kind of loosely philosophically that the reason we don’t remember the first few years of life, infantile amnesia is because how traumatic it is. Basically the error rate that you mentioned when your brain’s prediction doesn’t match reality, the error rate in the first few years of life, your first few months certainly, is probably crazy high. It’s non-stop freaking out. The collision between your model of the world and how the world works is just so high that you want whatever the trauma of that is not to linger around. I always thought that’s an interesting idea because just imagine the insanity of what’s happening in a human brain in the first couple of years.

You don’t know anything and there’s just this stream of knowledge and we’re somehow, given how plastic everything is, it just kind of molds and figures it out. But it’s like an insane waterfall of information.
Charan Ranganath
I wouldn’t necessarily describe it as a trauma and we can get into this whole stages of life thing, which I just love. Basically those first few years there are, I mean think about it, a kid’s internal model of their body is changing. It’s just learning to move. I mean, if you ever have a baby, you’ll know that the first three months they’re discovering their toes. It’s just nuts. So everything is changing. But what’s really fascinating is, and I think this is one of those, this is not at all me being a scientist, but it’s one of those things that people talk about when they talk about the positive aspects of children is that they’re exceptionally curious and they have this kind of openness towards the world.

And so that prediction error is not a negative traumatic thing. I think it’s a very positive thing because it’s what they use, they’re seeking information. One of the areas that I’m very interested in is the prefrontal cortex. It’s an area of the brain that, I mean, I could talk all day about it, but it helps us use our knowledge to say, “Hey, this is what I want to do now. This is my goal, so this is how I’m going to achieve it,” and focus everything towards that goal. The prefrontal cortex takes forever to develop in humans. The connections are still being tweaked and reformed into late adolescence, early adulthood, which is when you tend to see mental illness pop up.
So it’s being massively reformed. Then you have about 10 years maybe of prime functioning of the prefrontal cortex, and then it starts going down again and you end up being older and you start losing all that frontal function. So I look at this and you’d say, “Okay,” you sit around episodic memory talks. While they always say children are worse than adults at episodic memory, older adults or worse than young adults at episodic memory. And I always would say, “God, this is so weird. Why would we have this period of time that’s so short when we’re perfect or optimal?” And I like to use that word optimal now because there’s such a culture of optimization right now.
And it’s like I realize I have to redefine what optimal is because for most of the human condition, I think we had a series of stages of life where you have basically adults saying, “Okay”, young adults saying, “I’ve got a child and I’m part of this village and I have to hunt and forage and get things done.” I need a prefrontal cortex so I can stay focused on the big picture and the long haul goals. Now I’m a child, I’m in this village, I’m kind of wandering around and I’ve got some safety, and I need to learn about this culture because I know so little. What’s the best way to do that? Let’s explore. I don’t want to be constrained by goals as much.
I want to really be free, play and explore and learn. So you don’t want a super tight prefrontal cortex. You don’t even know what the goals should be yet. If you’re trying to design a model that’s based on a bad goal, it’s not going to work well. So then you go late in life and you say, “Oh, why don’t you have a great prefrontal cortex then?” But I think, I mean if you go back and you think how many species actually stick around naturally long after their childbearing years are over, after the reproductive years are over? With menopause, from what I understand, menopause is not all that common in the animal world. So why would that happen?
And so I saw Alison Gopnik said something about this so I started to look into this, about this idea that really when you’re older in most societies, your job is no longer to form new episodic memories, it’s to pass on the memories that you already have, this knowledge about the world, what we call semantic memory, to pass on that semantic memory to the younger generations, pass on the culture. Even now in indigenous cultures, that’s the role of the elders. They’re respected, they’re not seen as people who are past it and losing it. And I thought that was a very poignant thing, that memory is doing what it’s supposed to throughout these stages of life.
Lex Fridman
So it is always optimal in a sense.

Charan Ranganath

Lex Fridman

Yeah. And for the ecology of the system. So I looked into this and it’s like another species that has menopause is orcas. Orca pods are led by the grandmothers. So it’s not the young adults, not the parents or whatever, the grandmothers. And so they’re the ones that pass on the traditions to I guess the younger generation of orcas. And if you look from what little I understand, different orca pods have different traditions. They hunt for different things. They have different play traditions, and that’s a culture. And so in social animals, evolution I think is designing brains that are really around, it’s obviously optimized for the individual but also for kin. And I think that the kin are part of this when they’re a part of this intense social group, the brain development should parallel that, the nature of the ecology.

Lex Fridman
Well, it’s just fascinating to think of the individual orca or human throughout its life in stages doing a kind of optimal wisdom development. So in the early days, you don’t even know what the goal is, and you figure out the goal and you optimize for that goal and you pursue that goal. And then all the wisdom you collect through that, then you share with the others in the system, the other individuals. And as a collective, then you kind of converge towards greater wisdom throughout the generations. So in that sense, it’s optimal. Us humans and orcas got something going on. It works.

Charan Ranganath
So we could think about this on a number of levels. Maybe I’ll give you the simplest version first, which is we tend to think of memories as these individual things and we can just access them, maybe a little bit like photos on your phone or something like that. But in the brain, the way it works is you have this distributed pool of neurons and the memories are kind of shared across different pools of neurons. And so what you have is competition, where sometimes memories that overlap can be fighting against each other. So sometimes we forget because that competition just wipes things out. Sometimes we forget because there aren’t the biological signals which we can get into, I would promote long-term retention.

Sometimes we forget because there aren’t the biological signals which we can get into, I would promote long-term retention.
And lots of times we forget because we can’t find the cue that sends us back to the right memory, and we need the right cue to be able to activate it. So for instance, in a neural network there is no… You wouldn’t go and you’d say, “This is the memory.” It’s like the whole network, I mean, the whole ecosystem of memories is in the weights of the neural network. And in fact, you could extract entirely new memories depending on how you feed.
Lex Fridman
You have to have the right query, the right prompt to access that whatever the part you’re looking for.

Charan Ranganath
That’s exactly right. That’s exactly right. And in humans, you have this more complex set of ways memory works. There’s, as I said, the knowledge or what you call semantic memory, and then there’s these memories for specific events, which we call episodic memory. And so there’s different pieces of the puzzle that require different kinds of cues. So that’s a big part of it too, is just this kind of what we call retrieval failure.

Yeah. And so memory researchers, we love to cut things up and say, “is memory one thing or is it two things? There’s two things or there’s three things?” And so, one of the things that, and there’s value in that, and especially experimental value in terms of being able to dissect things. In the real world, it’s all connected. Speak to your question, working memory is a term that was coined by Alan Battley. It’s basically thought to be this ability to keep information online in your mind right in front of you at a given time, and to be able to control the flow of that information, to choose what information is relevant, to be able to manipulate it and so forth.

It’s basically thought to be this ability to keep information online in your mind right in front of you at a given time, and to be able to control the flow of that information, to choose what information is relevant, to be able to manipulate it and so forth.
And one of the things that Alan did that was quite brilliant was he said, ” There’s this ability to kind of passively store information, see things in your mind’s eye or hear your internal monologue,” but we have that ability to keep information in mind. But then we also have this separate what he called a central executive, which is identified a lot with the prefrontal cortex. It’s this ability to control the flow of information that’s being kept active based on what it is you’re doing. Now, a lot of my early work was basically saying that this working memory, which some memory researchers would call short-term memory is not at all independent from long-term memory.
That is that a lot of executive function requires learning, and you have to have synaptic change for that to happen. But there’s also transient forms of memory. So one of the things I’ve been getting into lately is the idea that we form internal models of events. The obvious one that I always use is birthday parties. So you go to a child’s birthday party, once the cake comes out and you just see a candle, you can predict the whole frame set of events that happens later. And up until that point where the child blows out the candle, you have an internal model in your head of what’s going on. And so if you follow people’s eyes, it’s not actually on what’s happening, it’s going where the action’s about to happen, which is just fascinating.
So you have this internal model, and that’s a kind of a working memory product, it’s something that you’re keeping online that’s allowing you to interpret this world around you. Now, to build that model though, you need to pull out stuff from your general knowledge of the world, which is what we call semantic memory. And then you’d want to be able to pull out memories for specific events that happened in the past, which we call episodic memory. So in a way, they’re all connected, even though it’s different. The things that we’re focusing on and the way we organize information in the present, which is working memory, will play a big role in determining how we remember that information later, which people typically call long-term memory.
Lex Fridman
So if you have something like a birthday party and you’ve been to many before, you’re going to load that from disk into working memory, this model, and then you’re mostly operating on the model. And if it’s a new task, you don’t have a model so you’re more in the data collection?

Charan Ranganath
Yes. One of the fascinating things that we’ve been studying, and we’re not at all the first to do this, Jeff Sachs was a big pioneer in this, and I’ve been working with many other people, Ken Norman, Leyla, Devachi and Wade. Columbia has done some interesting stuff with this, is this idea that we form these internal models at particular points of high prediction error or points of, I believe also points of uncertainty, points of surprise or motivationally significant periods. And those points are when it’s maximally optimal to encode an episodic memory. So I used to think, “Oh, well, we’re just encoding episodic memories constantly. Boom, boom, boom, boom, boom.”

And those points are when it’s maximally optimal to encode an episodic memory. So I used to think, “Oh, well, we’re just encoding episodic memories constantly. Boom, boom, boom, boom, boom.”
But think about how much redundancy there is in all that. It’s just a lot of information that you don’t need. But if you capture an episodic memory at the point of maximum uncertainty, for the singular experience, it’s only going to happen once, but if you capture it at the point of maximum uncertainty or maximum surprise, you have the most useful point in your experience that you’ve grabbed. And what we see is that the hippocampus and these other networks that are involved in generating these internal models of events, they show a heightened period of connectivity or correlated activity during those breaks between different events, which we call event boundaries.
These are the points where you looked surprised or you cross from one room to another and so forth. And that communication is associated with a bump of activity in the hippocampus and better memory. And so if people have a very good internal model, throughout that event you don’t need to do much memory processing, you’re in a predictive mode. And so then at these event boundaries you encode, and then you retrieve and you’re like, “Okay, wait a minute. What’s going on here? Branganath is now talking about orcas, what’s going on?” And maybe you have to go back and remember reading my book to pull out the episodic memory to make sense of whatever it is I’m babbling about.
And so there’s this beautiful dynamics that you can see in the brain of these different networks that are coming together and then deaffiliating at different points in time that are allowing you to go into these modes. And so to speak to your original question, to some extent, when we’re talking about semantic memory and episodic memory and working memory, you can think about it as these processes that are unfolding as these networks come together and pull apart,
Training memory

I think improvement, it depends on what your definition of optimal is. What I say in the book is is that you don’t want to remember more, you want to remember better, which means focusing on the things that are important. That’s what our brains are designed to do. If you go back to the earliest quantitative studies of memory by Ebbinghaus, what you see is that he was trying so hard to memorize this arbitrary nonsense, and within a day, he lost about 60% of that information. He was basically using a very, very generous way of measuring it. As far as we know, nobody has managed to violate those basics of having people forget most of their experiences. If your expectation is that you should remember everything and that’s what your optimal is, you’re already off because this is just not what human brains are designed to do.

If your expectation is that you should remember everything and that’s what your optimal is, you’re already off because this is just not what human brains are designed to do.
On the other hand, what we see over and over again is that, basically, one of the cool things about the design of the brain is it’s always less is more. Less is more. I’ve seen estimates that the human brain uses something like 12 to 20 watts in a day. That’s just nuts, the low power consumption. It’s all about reusing information and making the most of what we already have. That’s why basically, again, what you see biologically is neuromodulators, for instance, these chemicals in the brain like norepinephrine, dopamine, serotonin. These are chemicals that are released during moments that tend to be biologically significant, surprise, fear, stress, et cetera. These chemicals promote lasting plasticity, essentially, some mechanisms by which the brain can, say, prioritize the information that you carry with you into the future.
Attention is a big factor as well, our ability to focus our attention on what’s important, and so there’s different schools of thought on training attention, for instance. One of my colleagues, Amishi Jha, she wrote a book called Peak Mind and talks about mindfulness as a method for improving attention and focus. She works a lot with military like Navy SEALs and stuff to do this kind of work with mindfulness meditation. Adam Gazzaley, another one of my friends and colleagues, has worked on training through video games actually as a way of training attention. So it’s not clear to me, one of the challenges, though, in training is you tend to overfit to the thing that you’re trying to optimize. If I’m looking at a video game, I can definitely get better at paying attention in the context of the video game, but you transfer it to the outside world, that’s very controversial.
Lex Fridman
The implication there is that attention is a fundamental component of remembering something, allocating attention to it, and then attention might be something that you could train, how you allocate attention and how you hold attention on a thing.

I can say that, in fact, we do in certain ways. If you are an expert in something, you are training attention. We did this one study of expertise in the brain. People used to think, let’s say, if you’re a bird expert or something, people will go, ” If you get really into this world of birds, you start to see the differences and your visual cortex is tuned up, and it’s all about plasticity of the visual cortex.” Vision researchers love to say everything is visual, but it’s like we did this study of working memory and expertise. One of the things that surprised us were the biggest effects as people became experts in identifying these different kinds of just crazy objects that we made up, as they developed this expertise of being able to identify what made them different from each other and what made them unique, we were actually seeing massive increases in activity in the prefrontal cortex.

This fits with some of the studies of chess experts and so forth that it’s not so much that you learn the patterns passively. You learn what to look for. You learn what’s important and what’s not. You can see this in any kind of expert professional athlete. They’re looking three steps ahead of where they’re supposed to be, so that’s a kind of a training of attention. Those are also what you’d call expert memory skills. If you take the memory athletes, I know that’s something we’re both interested in, so these are people who train in these competitions and they’ll memorize a deck of cards in a really short amount of time. There’s a great memory athlete, her name I think is pronounced Yänjaa Wintersoul.
I think she’s got a giant Instagram following. She had this YouTube video that went viral where she had memorized an entire Ikea catalog. How do people do this? By all accounts, from people who become memory athletes, they weren’t born with some extraordinary memory, but they practice strategies over and over and over again. The strategy that they use for memorizing a particular thing, it can become automatic, and you can just deploy it in an instant. Again, one strategy for learning the order of a deck of cards might not help you for something else that you need like remembering your way around Austin, Texas. But it’s going to be these, whatever you’re interested in, you can optimize for that. That’s just a natural byproduct of expertise.

Sure. It’s the whole concept of spaced repetition. When the thing is fresh, you have to remind yourself of it a lot and then, over time, you can wait a week, a month, a year before you have to recall the thing again. That way, you essentially have something like note cards that you can have tens of thousands of and can only spend 30 minutes a day and actually be refreshing all of that information, all of that knowledge. It’s really great. For Memory Palace, it’s a technique that allows you to remember things like the Ikea catalog by placing them visually in a place that you’re really familiar with, like, “I’m really familiar with this place,” so I can put numbers or facts or whatever you want to remember you can walk along that little palace and it reminds you.

It’s cool. There’s stuff like that that I think memory athletes could use, but I think also regular people can use. One of those things that I have to solve for myself is how to remember names. I’m horrible at it. I think it’s because when people introduce themselves, I have the social anxiety of the interaction where I’m like, “I know I should be remembering that,” but I’m freaking out internally about social interaction in general, and so therefore, I forget immediately, so I’m looking for good tricks for that.
Charan Ranganath
I feel like we’ve got a lot in common because when people introduce themselves to me, it’s almost like I have this just blank blackout for a moment, and then I’m just looking at them like, “What happened?” I look away or something. What’s wrong with me? I’m totally with you on this. The reason why it’s hard is that there’s no reason we should be able to remember names, because when you say you’re remembering a name, you’re not really remembering a name.

The reason why it’s hard is that there’s no reason we should be able to remember names, because when you say you’re remembering a name, you’re not really remembering a name.
Maybe in my case, you are, but, most of the time, you’re associating a name with a face and an identity, and that’s a completely arbitrary thing. Maybe in the olden days, somebody named Miller, it’s like they’re actually making flour or something like that. For the most part, it’s like these names are just utterly arbitrary, so you have no thing to latch on to. It’s not really a thing that our brain does very well to learn meaningless, arbitrary stuff. So what you need to do is build connections somehow, visualize a connection, and sometimes it’s obvious or sometimes it’s not. I’m trying to think of a good one for you now, but the first thing I think of is Lex Luthor-
Lex Fridman
That’s great.

Charan Ranganath
Yeah. Yeah, but I’m serious though that these kinds of weird association is now I’m building a richer network. One of the things that I find is you can have somebody’s name that’s just totally generic like John Smith or something, no offense to people with that name, if I see a generic name like that, but I’ve read John Smith’s papers academically and then I meet John Smith at a conference, I can immediately associate that name with that face ’cause I have this pre-existing network to lock everything in to.

You can build that network, and that’s what the method of loci or the Memory Palace technique is all about is you have a pre-existing structure in your head of your childhood home or this mental palace that you’ve created for yourself. So now you can put arbitrary pieces of information in different locations in that mental structure of yours and then you can walk through the different path and find all the pieces of information you’re looking for. The method of loci is a great method for just learning arbitrary things because it allows you to link them together and get that cue that you need to pop in and find everything.
Memory hacks
Lex Fridman
We should maybe linger on this Memory Palace thing just to make it obvious, ’cause when people were describing to me a while ago what this is, it seems insane. You literally think of a place like a childhood home or a home that you’re really visually familiar with and you literally place in that three-dimensional space facts or people or whatever you want to remember, and you just walk in your mind along that place visually and you can remember, remind yourself of the different things. One of the limitations is there is a sequence to it.

You can’t just go upstairs right away or something. You have to walk along the room. It’s really great for remembering sequences, but it’s also not great for remembering individual facts out of context. The full context of the tour, I think, is important, but it’s fascinating how the mind is able to do that. When you ground these pieces of knowledge into something that you remember well already, especially visually, it’s fascinating. I think you do that for any kind of sequence. I’m sure she used something like this for the Ikea catalog, something of this nature.
Charan Ranganath
Oh, yeah, absolutely. Absolutely. I think the principle here is, again, I was telling you this idea that memories can compete with each other. Well, I like to use this example, and maybe someday I’ll regret this, but I’ve used it a lot recently. Imagine if this were my desk, it could be cluttered with a zillion different things. Imagine it’s just cluttered with a whole bunch of yellow Post-it notes and on one of them I put my bank password on it. Well, it’s going to take me forever to find it. It’s just going to be buried under all these other Post-it notes. If it’s hot pink, it’s going to stand out and I find it really easily. That’s one way in which if things are distinctive, if you’ve processed information in a very distinctive way, then you can have a memory that’s going to last.

That’s one way in which if things are distinctive, if you’ve processed information in a very distinctive way, then you can have a memory that’s going to last.
That’s very good, for instance, for name/face associations. If I get something distinctive about you that’s it like you’ve got a very short hair, and maybe I can make the association with Lex Luthor that way or something like that. If I get something very specific, that’s a great cue. But the other part of it is what if I just organized my notes so that I have my finances in one pile and I have my reminders, my to-do list in one pile and so forth so I organize them. Well, then, I know exactly if I’m going for my bank password, I could go to the finance pile. The method of loci works or Memory Palaces work because they give you a way of organizing.
There’s a school of thought that says that episodic memory evolved from this knowledge of space and basically there’s primitive abilities to figure out where you are, and so people explain the method of loci that way. Whether or not the evolutionary argument is true, the method of loci is not at all special. If you’re not a good visualizer, stories are a good one. So a lot of memory athletes will use stories and they’ll go, like if you’re memorizing a deck of cards, they have a little code for the different, the King and the Jack and the 10 and so forth. They’ll make up a story about things that they’re doing and that’ll work. Songs are a great one. I can still remember there’s this obscure episode of the TV show Cheers. They song about Albania that he uses to memorize all these facts about Albania. I could still sing that song to you as just as I saw it on the TV show.
Lex Fridman
So you mentioned space repetition. So do you like this process? Maybe can you explain it?
So you mentioned space repetition. So do you like this process? Maybe can you explain it?
Charan Ranganath
Oh, yeah. If I am trying to memorize something, let’s say if I have an hour to memorize as many Spanish words as I can, if I just try to do half-an-hour and then later in the day I do half-an-hour, I won’t retain that information as long as if I do half-an-hour today and half-an-hour one week from now. So doing that extra spacing should help me retain the information better. Now, there’s an interesting boundary condition, which is, it depends on when you need that information. So many of us, for me, I can’t remember so much from college and high school ’cause I crammed ’cause I just did everything at the last minute. Sometimes I would literally study in the hallway right before the test, and that was great because what would happen is is I just had that information right there.

Sometimes I would literally study in the hallway right before the test, and that was great because what would happen is is I just had that information right there.
So actually, not spacing can really help you if you need it very quickly, but the problem is is that you tend to forget it later on. But on the other hand, if you space things out, you get a benefit for later on retention. So there’s many different explanations. We have a computational model of this. It’s currently under revision. But in our computer model, what we say is that maybe a good way of thinking about this is this conversation that you and I are having, it’s associated with a particular context, a particular place in time. So all of these little cues that are in the background, these little guitar sculptures that you have and that big light umbrella thing, all these things are part of my memory for what we’re talking about, the content. So now later on, you’re sitting around, and you’re at home drinking a beer and you’re thinking, “God, what a strange interview that was,” right?
So now you’re trying to remember it, but the context is different. So your current situation doesn’t match up with the memory that you pulled up, there’s error. There’s a mismatch between what you’ve pulled up and your current context. So in our model, what you start to do is you start to erase or alter the parts of the memory that are associated with a specific place and time, and you heighten the information about the content. So if you remember this information in different times in different places, it’s more accessible at different times in different places because it’s not overfitted in an AI way of thinking about things. It’s not overfitted to one particular context. But that’s also why the memories that we call upon the most also feel like they’re just things that we read about almost. You don’t vividly reimagine them, right? It’s like they’re just these things that just come to us, like facts, right?
Lex Fridman
Yeah.
Yeah.
Charan Ranganath
It’s a little bit different than semantic memory, but it’s like basically these events that we have recalled over and over and over again, we keep updating that memory so it’s less and less tied to the original experience. But then we have those other ones, which it’s like you just get a reminder of that very specific context. You smell something, you hear a song, you see a place that you haven’t been to in a while, and boom, it just comes back to you. That’s the exact opposite of what you get with spacing, right?

That’s so fascinating. So with space repetition, one of its powers is that you lose attachment to a particular context, but then it loses the intensity of the flavor of the memory.

Charan Ranganath
Yeah, and I think this falls into a category. We’ve done other modeling. One of these is a published study in PLOS Computational Biology where we showed that another way, which is, I think, related to the spacing effect is what’s called the testing effect. So the idea is that if you’re trying to learn words, let’s say in Spanish or something like that, and this doesn’t have to be words, it could be anything, you test yourself on the words. That act of testing yourself helps you retain it better over time than if you just studied it. So from traditional learning theories, some learning theories, anyway, this seems weird, why would you do better giving yourself this extra error from testing yourself rather than just giving yourself perfect input that’s a replica of what it is that you’re trying to learn?

I think the reason is is that you get better retention from that error, that mismatch that we talked about. So what’s happening in our model, it’s actually conceptually similar to what happens with backprop in AI or neural networks. So the idea is that you expose, “Here’s the bad connections, and here’s the good connections.” So we can keep the parts of the cell assembly that are good for the memory and lose the ones that are not so good. But if you don’t stress test the memory, you haven’t exposed it to the error fully. So that’s why I think this is a thing that I come back to over and over again, is that you will retain information better if you’re constantly pushing yourself to your limit. If you are feeling like you’re coasting, then you’re actually not learning, so it’s like-
Lex Fridman
You should always be stress testing the memory system.
You should always be stress testing the memory system.
Charan Ranganath
Yeah, and feel good about it. Even though everyone tells me, “Oh, my memory is terrible,” in the moment they’re overconfident about what they’ll retain later on. So it’s fascinating. So what happens is when you test yourself, you’re like, “Oh, my God, I thought I knew that, but I don’t.” So it can be demoralizing until you get around that and you realize, “Hey, this is the way that I learn. This is how I learned best.” It’s like if you’re trying to star in a movie or something like that, you don’t just sit around reading the script. You actually act it out, and you’re going to botch those lines from time to time, right?

You know what? There’s an interesting moment, you probably have experienced this. I remember a good friend of mine, Joe Rogan, I was on his podcast, and we were randomly talking about soccer, football, somebody I grew up watching Diego Armando Maradona, one of the greatest soccer players of all time. We were talking about him and his career and so on, and Joe asked me if he’s still around. I said, ” Yeah.” I don’t know why I thought, “Yeah,” because that was a perfect example of memories. He passed away. I tweeted about it, how heartbroken I was, all this kind of stuff a year before.

I know this, but in my mind, I went back to the thing I’ve done many times in my head of visualizing some of the epic runs he had on goal and so on. So for me, he’s alive. Part of also the conversation when you’re talking to Joe, there’s stress and the focus is allocated. The attention is allocated in a particular way. But when I walked away, I was like, “In which world was Diego Maradona still alive?” ‘Cause I was sure in my head that he was still alive. It’s a moment that sticks with me. I’ve had a few like that in my life where it just… obvious things just disappear from mind, and it’s cool. It shows actually the power of the mind in the positive sense to erase memories you want erased maybe, but I don’t know. I don’t know if there’s a good explanation for that.
Imagination vs memory
Charan Ranganath
One of the cool things that I found is that some people really just revolutionize a field by creating a problem that didn’t exist before. It’s why I love science is engineering is like solving other people’s problems and science is about creating problems. I’m just much more like I want to break things and create problems, not necessarily move fast, though. But one of my former mentors, Marcia Johnson, who in my opinion is one of the greatest memory researchers of all time, she comes up young woman in the field in this mostly guy field. She gets into this idea of how do we tell the difference between things that we’ve imagined and things that we actually remember? How do we tell, I get some mental experience, where did that mental experience come from? It turns out this is a huge problem because essentially our mental experience of remembering something that happened, our mental experience of thinking about something, how do you tell the difference? They’re both largely constructions in our head, and so it is very important. The way that you do it is, it’s not perfect, but the way that we often do it and succeed is by, again, using our prefrontal cortex and really focusing on the sensory information or the place in time and the things that put us back into when this information happened. If it’s something you thought about, you’re not going to have all of that vivid detail as you do for something that actually happened, but it doesn’t work all the time. But that’s a big thing that you have to do. But it takes time. It’s slow, and it’s again, effortful, but that’s what you need to remember accurately.

But what’s cool, and I think this is what you alluded to about how that was an interesting experience is, imagination is exactly the opposite. Imagination is basically saying, “I’m just going to take all this information from memory, recombine it in different ways and throw it out there.” So for instance, Dan Schachter and Donna Addis have done cool work on this. Demis Hassabis did work on this with Eleanor McGuire in UCL, and this goes back actually to this guy, Frederic Bartlett, who is this revolutionary memory researcher, Bartlett. He actually rejected the whole idea of quantifying memory. He said, “There’s no statistics in my book.” He came from this anthropology perspective and short version of the story is he just asked people to recall things. You give people stories and poems, ask people to recall them.
What we found was people’s memories didn’t reflect all of the details of what they were exposed to, and they did reflect a lot more… they were filtered through this lens of prior knowledge; the cultures that they came from, the beliefs that they had, the things they knew. So what he concluded was that he called remembering an imaginative construction, meaning that we don’t replay the past, we imagine how the past could have been by taking bits and pieces that come up in our heads. Likewise, he wrote this beautiful paper on imagination saying when we imagine something and create something, we’re creating it from these specific experiences that we’ve had and combining it with our general knowledge. But instead of trying to focus it on being accurate and getting out one thing, you’re just ruthlessly recombining things without any necessary goal in mind, or at least that’s one kind of creation.
Lex Fridman
So imagination is fundamentally coupled with memory in both directions.

Charan Ranganath
I think so. It’s not clear that it is in everyone, but one of the things that’s been studied is some patients who have amnesia, for instance, they have brain damage, say, to the hippocampus. If you ask them to imagine things that are not in front of them, imagine what could happen after I leave this room, they find it very difficult to give you a scenario what could happen. Or if they do, it would be more stereotyped like, “Yes, this would happen, this would…” But it’s not like they can come up with anything that’s very vivid and creative in that sense. It’s partly ’cause when you have amnesia, you’re stuck in the present because to get a very good model of the future, it really helps to have episodic memories to draw upon, and so that’s the basic idea. In fact, one of the most impressive things when people started to scan people’s brains and ask people to remember past events, what they found was there was this big network of the brain called the default mode network.

It gets a lot of press because it’s thought to be important. It’s engaged during mind wandering. If I ask you to pay attention to something, it only comes on when you stop paying attention, so people, “Oh, it’s just this kind of daydreaming network.” I thought, “This is just ridiculous research. Who cares?” But then what people found was when people recall episodic memories, this network gets active. So we started to look into it, and this network of areas is really closely functionally interacting with the hippocampus. So in fact, some would say the hippocampus is part of this default network. If you look at brain images of people or brain maps of activation, so to speak, of people imagining possible scenarios of things that could happen in the future or even things that couldn’t really be very plausible, they look very similar.
To the naked eye, they look almost the same as maps of brain activation when people remember the past. According to our theory, and we’ve got some data to support this, we’ve broken up this network in various sub pieces, is that basically it’s taking apart all of our experiences and creating these little Lego blocks out of them. Then you can put them back together if you have the right instructions to recreate these experiences that you’ve had, but you could also reassemble them into new pieces to create a model of an event that hasn’t happened yet, and that’s what we think happens when our common ground that we’re establishing in language requires using those building blocks to put together a model of what’s going on.
Lex Fridman
Well, there’s a good percentage of time I personally live in the imagined world. I do thought experiments a lot. I take the absurdity of human life as it stands and play it forward in all kinds of different directions. Sometimes it’s rigorous thoughts, thought experiments, sometimes it’s fun ones. So I imagine that that has an effect on how I remember things. I suppose I have to be a little bit careful to make sure stuff happened versus stuff that I just imagined happened. Some of my best friends are characters inside books that never even existed. There’s some degree to which they actually exist in my mind. Like these characters exist, authors exist, Dostoevsky exists, but also Brothers Karamazov.

Yeah, there was actually this famous mnemonist, he’s like back then the equivalent of a memory athlete, except he would go to shows and do this, that was described by this really famous neuropsychologist from Russia named Luria. So this guy was named Solomon Shereshevsky, and he had this condition called synesthesia that basically created these weird associations between different senses that normally wouldn’t go together. So that gave him this incredibly vivid imagination that he would use to basically imagine all sorts of things that he would need to memorize, and he would just imagine, just create these incredibly detailed things in his head that allowed him to memorize all sorts of stuff.

But it also really haunted him by some reports that basically it was like he was at some point, and again, who knows if the drinking was part of this, but he at some point had trouble differentiating his imagination from reality. This is interesting because it’s like that’s what psychosis is in some ways is first of all, you’re just learning connections from prediction errors that you probably shouldn’t learn. The other part of it is is that your internal signals are being confused with actual things in the outside world. Right?
Lex Fridman
Well, that’s why a lot of this stuff is both feature and bug. It’s a double-edged sword.

Memory competitions

Can we just talk about memory sport a little longer? There’s something called the USA Memory Championship. What are these athletes like? What does it mean to be elite level at this? Have you interacted with any of them or reading about them, what have you learned about these folks?

Charan Ranganath
… athlete, they often have these life events that make them go, “Hey, why don’t I do this?” So there was a guy named Scott Hagwood who I write about, who thought that he was getting chemo for cancer. And so he decided, because chemo, there’s a well-known thing called chemo brain where people become, they just lose a lot of their sharpness. And so he wanted to fight that by learning these memory skills. So he bought a book, and this is the story you hear in a lot of memory athletes is they buy a book by other memory athletes or other memory experts, so to speak. And they just learn those skills and practice them over and over again. They start by winning bets and so forth. And then they go into these competitions. And the competitions are typically things like memorizing long strings of numbers or memorizing orders of cards and so forth. So they tend to be pretty arbitrary things, not things that you’d be able to bring a lot of prior knowledge. But they build the skills that you need to memorize arbitrary things.

Yeah, that’s fascinating. I’ve gotten a chance to work with something called n-back tasks. So there’s all these kinds of tasks, memory recall tasks that are used to kind of load up the quote-unquote, working memory.

The psychologist used it to test all kinds of stuff to see how well you’re good at multitasking. We used it in particular for the task of driving. If we fill up your brain with intensive working memory tasks, how good are you at also not crashing, that kind of stuff. So it’s fascinating, but again, those tasks are arbitrary and they’re usually about recalling a sequence of numbers in some kind of semi-complex way. Do you have any favorite tasks of this nature in your own studies?

I’ve really been most excited about going in the opposite direction and using things that are more and more naturalistic. And the reason is that we’ve moved in that direction because what we found is that memory works very, very differently when you study memory in the way that people typically remember. And so it goes into a much more predictive mode. And you have these event boundaries, for instance, and you have… But a lot of what happens is this kind of fascinating mix that we’ve been talking about, a mix of interpretations and imagination with perception. And the new direction we’re going in is understanding navigation in our memory [inaudible 01:06:44] places. And the reason is that there’s a lot of work that’s done in rats, which is very good work. They have a rat and they put it in a box and the rat goes chases cheese in a box. You’ll find cells in the hippocampus that fire when a rat is in different places in the box.

They have a rat and they put it in a box and the rat goes chases cheese in a box. You’ll find cells in the hippocampus that fire when a rat is in different places in the box.
And so the conventional wisdom is that the hippocampus forms this map of the box. And I think that probably may happen when you have absolutely no knowledge of the world, right? But I think one of the cool things about human memory is we can bring to bear our past experiences to economically learn new ones. And so for instance, if you learn a map of an IKEA, let’s say if I go to the IKEA in Austin, I’m sure there’s one here. I probably could go to this IKEA and find my way to where the wine glasses are without having to even think about it because it’s got a very similar layout, even though IKEA is a nightmare to get around. Once I learned my local IKEA, I can use that map everywhere. Why form a brand new one for a new place? So that kind of ability to reuse information really comes into play when we look at things that are more naturalistic tasks.
And another thing that we’re really interested in is this idea of what if instead of basically mapping out every coordinate in a space, you form a pretty economical graph that connects basically the major landmarks together? And being able to use that as emphasizing the things that are most important, the places that you go for food and the places that are landmarks that help you get around. And then filling in the blanks for the rest, because I really believe that cognitive maps or mental maps of the world, just like our memories for events are not photographic. I think they’re this combination of actual verifiable details and then a lot of inference that you make.
Lex Fridman
What have you learned about this kind of spatial mapping of places? How do people represent locations?
What have you learned about this kind of spatial mapping of places? How do people represent locations?
Charan Ranganath
There’s a lot of variability, I think that… And there’s a lot of disagreement about how people represent locations. In a world of GPS and physical maps, people can learn it from basically what they call a survey perspective, being able to see everything. And so that’s one way in which humans can do it that’s a little bit different. There’s one way which we can memorize routes. I know how to get from here to, let’s say if I walk here from my hotel, I could just rigidly follow that route back, right? And there’s another more integrative way, which would be what’s called a cognitive map. Which would be kind of a sense of how everything relates to each other. And so there’s lots of people who believe that these maps that we have in our head are isomorphic with the world, that are these literal coordinates that follow Euclidean space. And as you know, Euclidean mathematics is very constrained, right?

And so there’s lots of people who believe that these maps that we have in our head are isomorphic with the world, that are these literal coordinates that follow Euclidean space. And as you know, Euclidean mathematics is very constrained, right?
And I think that we are actually much more generative in our maps of space so that we do have these bits and pieces. And we’ve got a small task, it’s right now, not yet… we need to do some work on it for further analyses. But one of the things we’re looking at is these signals called ripples in the hippocampus, which are these bursts of activity that you see that are synchronized with areas in the neocortex, in the default network actually. And so what we find is that those ripples seem to increase at navigationally important points when you’re making a decision or when you reach a goal. This speaks to the emotion thing, right? Because if you have limited choices, if I’m walking down a street, I could really just get a mental map of the neighborhood with a more minimal kind of thing by just saying, “Here’s the intersections and here’s the directions I take to get in between them.”
And what we found in general in our MRI studies is basically the more people can reduce the problem, whether it’s space or any kind of decision-making problem, the less the hippocampus encodes. It really is very economical towards the points of most highest information, content and value.
Lex Fridman
So can you describe the encoding in the hippocampus and the ripples you were talking about? What’s the signal in which we see the ripples?
So can you describe the encoding in the hippocampus and the ripples you were talking about? What’s the signal in which we see the ripples?
Charan Ranganath
Yeah, so this is really interesting. There are these oscillations, right? So there’s these waves that you basically see. And these waves are points of very high excitability and low excitability. And at least during… They happen actually during slow-wave sleep too. So the deepest stages of sleep, when you’re just zonked out, right? You see these very slow waves, where it’s very excitable and then very unexcitable, it goes up and down. And on top of them you’ll see these little sharp wave ripples. And when there’s a ripple in the hippocampus, you tend to see a sequence of cells that resemble a sequence of cells that fire when an animal is actually doing something in the world. So it almost is like a little, people call it replay, I think it’s a little bit… I don’t like that term, but it’s basically a little bit of a compressed play of the sequence of activity in the brain that was taking place earlier.

And during those moments, there’s a little window of communication between the hippocampus and these areas in the neocortex. And so that I think helps you form new memories, but it also helps you, I think, stabilize them, but also really connect different things together in memory. And allows you to build bridges between different events that you’ve had. And so this is one of at least our theories of sleep, and its real role in helping you see the connections between different events that you’ve experienced.
Lex Fridman
So during sleep is when the connections are formed?
So during sleep is when the connections are formed?

Lex Fridman
Yeah.
Yeah.
Charan Ranganath
So it’s like you see me now, you see me next week, you see me a month later. You start to build a little internal model of how I behave and what to expect of me. And we think sleep, one of the things it allows you to do is figure out those connections and connect the dots and find the signal in the noise.

Science of memory
Lex Fridman
So you mentioned fMRI. What is it? And how is it used in studying memory?
So you mentioned fMRI. What is it? And how is it used in studying memory?
Charan Ranganath
This is actually the reason why I got into this whole field of science is when I was in grad school, fMRI was just really taking off as a technique for studying brain activity. And what’s beautiful about it is you can study the whole human brain. And there’s lots of limits to it, but you can basically do it in a person without sticking anything into their brains, and very non-invasive. For me being in an MRI scanner is like being in the womb, I just fall asleep. If I’m not being asked to do anything, I get very sleepy. But you can have people watch movies while they’re being scanned or you can have them do tests of memory, giving them words and so forth to memorize. But what MRI is itself is just this technique where you put people in a very high magnetic field. Typical ones we would use would be 3 Tesla to give you an idea.

But what MRI is itself is just this technique where you put people in a very high magnetic field. Typical ones we would use would be 3 Tesla to give you an idea.
So a 3 Tesla magnet, you put somebody in, and what happens is you get this very weak but measurable magnetization in the brain. And then you apply a radio frequency pulse, which is basically a different electromagnetic field. And so you’re basically using water, the water molecules in the brain as a tracer, so to speak. And part of it in fMRI is the fact that these magnetic fields that you mess with by manipulating these radio frequency pulses and the static field, and you have things called gradients, which change the strength of the magnetic field in different parts of the head. So we tweak them in different ways, but the basic idea that we use in fMRI is that blood is flowing to the brain. And when you have blood that doesn’t have oxygen on it, it’s a little bit more magnetizable than blood that does because you have hemoglobin that carries the oxygen, the iron basically in the blood that makes it red.
And so that hemoglobin, when it’s deoxygenated actually has different magnetic field properties than when it has oxygen. And it turns out when you have an increase in local activity in some part of the brain, the blood flows there. And as a result you get a lower concentration of hemoglobin that is not oxygenated, and then that gives you more signal. So I gave you, I think I sent you a GIF, as you like to say.
Lex Fridman
Yeah, we had off-record intense argument about if it’s pronounced GIF or GIF, but we shall set that aside as friends.

This would be basically a whole… a movie of fMRI data. And so when you look at it, it’s not very impressive, it looks like these very pixelated maps of the brain, but it’s mostly kind of white. But these tiny changes in the intensity of those signals that you probably wouldn’t be able to visually perceive, about 1% can be statistically very, very large effects for us. And that allows us to see, “Hey, there’s an increase in activity in some part of the brain when I’m doing some task like trying to remember something.” And I can use those changes to even predict, is a person going to remember this later or not? And the coolest thing that people have done is to decode what people are remembering from the patterns of activity from… Because maybe when I’m remembering this thing, I’m remembering the house where I grew up. I might have one pixel that’s bright in the hippocampus and one that’s dark.

I might have one pixel that’s bright in the hippocampus and one that’s dark.
And if I’m remembering something more like the car that I used to drive when I was 16, I might see the opposite pattern where a different pixel is bright. And so all that little stuff that we use to think of noise, we can now think of almost like a QR code for memory, so to speak. Where different memories have a different little pattern of bright pixels and dark pixels. And so this really revolutionized my research. So there’s fancy research out there where people really… not even that f… by your standards, this would be Stone Age, but applying machine learning techniques to do decoding and so forth. And now there’s a lot of forward encoding models and you can go to town with this stuff, right? And I’m much more old school of designing experiments where you basically say, “Okay, here’s a whole web of memories that overlap in some way, shape or form.” Do memories that occurred in the same place have a similar QR code? And do memories that occurred in different places have a different QR code?
And you can just use things like correlation coefficients or cosine distance to measure that stuff, right? Super simple, right? And so what happens is you can start to get a whole state space of how a brain area is indexing all these different memories. It’s super fascinating because what we could see is this little separation between how certain brain areas are processing memory for who was there. And other brain areas are processing information about where it occurred, or the situation that’s kind of unfolding. And some are giving you information about what are my goals that are involved and so forth. And the hippocampus is just putting it all together into these unique things that just are of about when and where it happened.
Lex Fridman
So there’s a separation between spatial information concepts, literally there’s distinct, as you said, QR codes for these?
So there’s a separation between spatial information concepts, literally there’s distinct, as you said, QR codes for these?
Charan Ranganath
So to speak. Let me try a different analogy too, that might be more accessible for people. Which would be, you’ve got a folder on your computer, right? I open it up, there’s a bunch of files there. I can sort those files by alphabetical order. And now things that both start with letter A are lumped together, and things that start with Z versus A are far apart, right?

Lex Fridman
Mm-hmm.
Mm-hmm.
Charan Ranganath
And so that is one way of organizing the folder, but I could do it by date. And if I do it by date, things that were created close together in time are close, and things that are far apart in time are far. So you can think of how a brain area or a network of areas contributes to memory by looking at what the sorting scheme is. And these QR codes that we’re talking about that you get from fMRI allow you to do that. And you can do the same thing if you’re recording from massive populations of neurons in an animal. And you can do it for recording local potentials in the brain. So little waves of activity in let’s say a human who has epilepsy and they stick electrodes in their brain to try to find seizures. So that’s some of the work that we’re doing now.

But all of these techniques basically allow you to say, “Hey, what’s the sorting scheme?” And so we’ve found that some networks of the brain sort information in memory according to who was there. So I might have… We’ve actually shown in one of my favorite studies of all time that was done by a former postdoc, Zach Reagh. And Zach did the study where we had a bunch of movies with different people in my labs that are two different people. And you filmed them at two different cafes and two different supermarkets. And what you could show is in one particular network, you could find the same kind of pattern of activity, more or less, a very similar pattern of activity. Every time I saw Alex in one of these movies, no matter where he was, right? And I could see another one that was a common pattern that happened every time I saw this particular supermarket nugget. And it didn’t matter whether you’re watching a movie or whether you’re recalling the movie, it’s the same kind of pattern that comes up, right?
Lex Fridman
It’s so fascinating.
It’s so fascinating.
Charan Ranganath
It is fascinating. And so now you have those building blocks for assembling a model of what’s happening in the present, imagining what could happen, and remembering things very economically from putting together all these pieces. So that all the hippocampus has to do is get the right kind of blueprint for how to put together all these building blocks.

These are all beautiful hints at a super interesting system that makes me wonder on the other side of it how to build it. But it’s fascinating the way it does the encoding is really, really fascinating. Or I guess the symptoms, the results of that encoding are fascinating to study from this. Just as a small tangent, you mentioned sort of the measuring local potentials with electrodes versus fMRI.

What are some interesting limitations, possibilities of fMRI? The way you explained it is brilliant with blood and detecting the activations or the excitation because blood flows to that area. What’s the latency of that? What’s the blood dynamics in the brain that… How quickly can the tasks change and all that kind of stuff?

Charan Ranganath
Yeah, it’s very slow. To the brain, 50 milliseconds, it’s an eternity. Maybe not 50 mil… maybe let’s say half a second, 500 milliseconds, just so much back and forth stuff happens in the brain in that time, right? So in fMRI, you can measure these magnetic field responses about six seconds after that burst of activity would take place. All these things, it’s like is it a feature or is it a bug? Right? So one of the interesting things that’s been discovered about fMRI is it’s not so tightly related to the spiking of the neurons. So we tend to think of the computation, so to speak, as being driven by spikes, meaning there’s just a burst of it’s either on or it’s off and the neurons going up or down. But sometimes what you can have is these states where the neuron becomes a little bit more excitable or less excitable.

So we tend to think of the computation, so to speak, as being driven by spikes, meaning there’s just a burst of it’s either on or it’s off and the neurons going up or down. But sometimes what you can have is these states where the neuron becomes a little bit more excitable or less excitable.
And so fMRI is very sensitive to those changes in excitability. Actually, one of the fascinating things about fMRI is where does that… how is it we go from neural activity to essentially blood flow to oxygen? All this stuff. It’s such a long chain of going from neural activity to magnetic fields. And one of the theories that’s out there is most of the cells in the brain are not neurons, they’re actually these support cells called glial cells. And one big one is astrocytes, and they play this big role in regulating, kind of being a middle man, so to speak, with the neurons. So if, for instance, one neuron’s talking to another, you release a neurotransmitter like let’s say glutamate. And that gets another neuron, starts getting active after you release it in the gap between the two neurons called the synapse.
So what’s interesting is if you leave that, imagine you’re just flooded with this liquid in there, right? If you leave it in there too long, you just excite the other neuron too much and you can start to basically get seizure activity. You don’t want this, so you got to suck it up. And so actually what happens is these astrocytes, one of their functions is to suck up the glutamate from the synapse. And that is a massively… And then break it down and then feed it back into the neuron so that you could reuse it. But that cycling is actually very energy intensive. And what’s interesting is at least according to one theory, they need to work so quickly that they’re working on metabolizing the glucose that comes in without using oxygen. Kind of like anaerobic metabolism, so they’re not using oxygen as fast as they’re using glucose. So what we’re really seeing in some ways may be in fMRI, not the neurons themselves being active, but rather the astrocytes which are meeting the metabolic demands of the process of keeping the whole system going.
Lex Fridman
It does seem to be that fMRI is a good way to study activation. So with these astrocytes, even though there’s a latency, it’s pretty reliably coupled to the activations.

Charan Ranganath
Oh, well, this gets me to the other part. So now let’s say for instance, if I’m just kind of I’m talking to you, but I’m kind of paying attention to your cowboy hat, right? So I’m looking off to the… Or I’m thinking about the [inaudible 01:26:12], even if I’m not looking at it. What you’d see is that there’d be this little elevation in activity in areas in the visual cortex, which process vision around that point in space, okay? So if then something happened like a suddenly a light flashed in that part of… right in front of your cowboy hat, I would have a bigger response to it. But what you see in fMRI is even if I don’t see that flash of light, there’s a lot of activity that I can measure because you’re kind of keeping it excitable [inaudible 01:26:46] that in and of itself, even though I’m not seeing anything there that’s particularly interesting, there’s still this increase in activity.

So it’s more sensitive with fMRI. So is that a feature or is it a bug? People who study spikes in neurons would say, “Well, that’s terrible, we don’t want that.” Likewise, it’s slow, and that’s terrible for measuring things that are very fast. But one of the things that we found in our work was when we give people movies and when we give people stories to listen to, a lot of the action is in the very, very slow stuff. Because if you’re thinking about a story, let’s say you’re listening to a podcast or something, you’re listening to Lex Fridman Podcast, right? You’re putting this stuff together and building this internal model over several seconds. Which is basically we filter that out when we look at electrical activity in the brain because we’re interested in this millisecond scale, it’s almost massive amounts of information, right? So the way I see it is every technique gives you a little limited window into what’s going on.
fMRI has huge problems, people lie down in the scanner. There’s parts of the brain where… I will show you in some of these images where you’ll see kind of gaping holes because you can’t keep the magnetic field stable in those spots. You’ll see parts where it’s like there’s a vein, and so it just produces big increase and decrease in signal or respiration that causes these changes. There’s lots of artifacts and stuff like that. Every technique has its limits. If I’m lying down in an MRI scanner, I’m lying down. I’m not interacting with you in the same way that I would in the real world. But at the same time, I’m getting data that I might not be able to get otherwise. And so different techniques give you different kinds of advantages.
Discoveries
Lex Fridman
What kind of big scientific discoveries, maybe the flavor of discoveries have been done throughout the history of the science of memory, the studying of memory? What kind of things have been understood?

Oh, there’s so many, it’s really so hard to summarize it. I think it’s funny because it’s like when you’re in the field, you can get kind of blasé about this stuff. But then once I started write the book, I was like, “Oh my God, this is really interesting. How did we do all this stuff?” I would say that some of the… From the first study, it’s just showing how much we forget is very important. Showing how much schemas, which is our organized knowledge about the world increase our ability to remember information, just massively increase in [inaudible 01:29:25] of expertise. Showing how experts like chess experts can memorize so much in such a short amount of time because of the schemas they have for chess. But then also showing that those lead to all sorts of distortions in memory.

The discovery that the act of remembering can change the memory, it can strengthen it, but it can also distort it if you get misinformation at the time. And it can also strengthen or weaken other memories that you didn’t even recall. So just this whole idea of memory as an ecosystem I think was a big discovery. I could go, this idea of breaking up our continuous experience into these discrete events, I think was a major discovery.

Charan Ranganath
Maybe, yeah, and again, there’s controversial ideas about this, right? But it’s like, yeah, this idea that… And this gets back to just this common experience of you walk into the kitchen and you’re like, “Why am I here?” And you just end up grabbing some food from the fridge. And you go back and you’re like, “Oh, wait a minute, I left my watch in the kitchen. That’s what I was looking for.” And so what happens is that you have a little internal model of where you are, what you’re thinking about. And when you cross from one room to another, those models get updated. And so now when you’re in the kitchen, have to go back and mentally time travel back to this earlier point to remember what it was that you went there for. And so these event boundaries turns out in our research, and again, I don’t want to make it sound like we’ve figured out everything. But in our research, one of the things that we found is that basically, as people get older, the activity in the hippocampus at these event boundaries tends to go down, but independent of age.

If I give you outside of the scanner, you’re done with the scanner, I just scan you while you’re watching a movie, just watch it. You come out, I give you a test of memory for stories. What happens is you find this incredible correlation between the activity in the hippocampus at these singular points in time, these event boundaries. And your ability to just remember a story outside of the scanner later on. So it’s marking this ability to encode memories, just these little snippets of neural activity. So I think that’s a big one. There’s all sorts of work in animal models that I can get into. Sleep, I think there’s so much interesting stuff that’s being discovered in sleep right now.
Being able to just record from large populations of cells and then be able to relate that… [inaudible 01:32:03], I think the coolest thing gets back to this QR code thing, because what we can do now is I can take fMRI data while you’re watching a movie. Let’s do better than that. Let me get fMRI data while you use a joystick to move around in virtual reality. So you’re in the metaverse, whatever. But it’s kind of a crappy metaverse because there’s only so much metaversing you can do in an MRI scanner. So you’re doing this crappy metaversing. So now, I can take a rat, record from its hippocampus and prefrontal cortex and all these areas with these really new electrodes that get massive amounts of data. And have it move around on a trackball in virtual reality in the same metaverse that I did, and record that rat’s activity.
I can get a person with epilepsy who we have electrodes in their brain anyway, to try to figure out where the seizures are coming from. And if it’s a healthy part of the brain, record from that person, right? And I can get a computational model. And one of the brand new members in my lab, Tyler Brown is just doing some great stuff. He relates computer vision models and looks at the weaknesses of computer vision models and relates to what the brain does well.
Lex Fridman
Mm-hmm. Nice.
Mm-hmm. Nice.
Charan Ranganath
And so you can actually take a ground truth code for the metaverse, basically, and you can feed in the visual information, let’s say the sensory information or whatever that’s coming in to a computational model that’s designed to take real world inputs, right? And you could basically tie them all together by virtue of the state spaces that you’re measuring in neural activity, in these different formats and these different species, and in the computational model. Which is I just find that mind-blowing. And you could do different kinds of analyses on language and basically come up with… Basically it’s the guts of LLMs, right? You could do analyses on language and you could do analyses on sentiment analyses of emotions and so forth. Put all this stuff together, it’s almost too much. But if you do it right and you do it in a theory-driven way as opposed to just throwing all the data at the wall and see what sticks, that to me is just exceptionally powerful.

So you can take fMRI data across species and across different types of humans or conditions of humans, and construct models that help you find the commonalities or the core thing that makes somebody navigate through the metaverse, for example?

Yeah. Yeah, more or less.

Charan Ranganath
Study neural circuits in an enormously targeted way because you could do these genetic studies, for instance, where you can manipulate particular groups of neurons, and it’s just getting more and more targeted to the point where you can actually turn on a particular kind of memory, just by activating a particular set of neurons that was active during an experience.

So, there’s a lot of conservation of some of these neural circuits across evolution in mammals, for instance. And then some people would even say that there’s genetic mechanisms for learning that are conserved, even going back far, far before. But let’s go back to the mice in humans question.
There’s a lot of differences. So, for one thing, the sensory information is very different. Mice and rats explore the world largely through smelling, olfaction, but they also have vision that’s kind of designed to catch death from above. So, it’s like a very big view of the world. And we move our eyes around in a way that focuses on particular spots in space where you get very high resolution from a very limited set of spots in space. So, that makes us very different in that way.
We also have all these other structures as social animals that allow us to respond differently. There’s language, there’s… you name it, there’s obviously gobs of differences. Humans aren’t just giant rats. There’s much more complexity to us. Timescales are very important. So, primate brains and human brains are especially good at integrating and holding on to information across longer and longer periods of time.
Also, finally, it’s like our history of training data, so to speak, is very, very different than… Human’s world is very different than a wild mouse’s world. And a lab mouse’s world is extraordinarily impoverished relative to an adult human. Yeah.
Lex Fridman
But still, what can you understand by studying mice? I mean, just basic, almost behavioral stuff about memory?
But still, what can you understand by studying mice? I mean, just basic, almost behavioral stuff about memory?
Charan Ranganath
Well, yes, but that’s very important. So, you can understand, for instance, how do neurons talk to each other? That’s a really big, big question. Neural computation, in and of itself… You think it’s the most simple question, right? Not at all. I mean, it’s a big, big question, and understanding how two parts of the brain interact, meaning that it’s not just one area, speaking it’s not like Twitter where one area of the brain’s shouting and then another area of the brain’s just stuck listening to this crap. It’s like they’re actually interacting on the millisecond scale.

It’s like they’re actually interacting on the millisecond scale.
How does that happen and how do you regulate those interactions, these dynamic interactions? We’re still figuring that out. But that’s going to be coming largely from model systems that are easier to understand. You can do manipulations, like drug manipulations, to manipulate circuits, and use viruses and so forth, and lasers to turn on circuits that you just can’t do in humans.
So, I think there’s a lot that can be learned from mice. There’s a lot that can be learned from non-human primates. And then there’s a lot that you need to learn from humans. And I think unfortunately, some of the people in the National Institutes of Health think you can learn everything from the mouse. It’s like, “Why study memory in humans when I could study learning in a mouse?” And just like, “Oh my God, I’m going to get my funding from somewhere else.”
Lex Fridman
Well, let me ask you some random fascinating question.
Well, let me ask you some random fascinating question.
Deja vu
Charan Ranganath
Yeah, sure.
Yeah, sure.
Lex Fridman
How does deja vu work?
How does deja vu work?
Charan Ranganath
So, deja vu, it’s actually one of these things I think that some of the surveys suggest that 75% of people report having a deja vu experience one time or another. I don’t know where that came from, but I’ve polled people in my class and most of them say they’ve experienced deja vu. It’s this kind of sense that I’ve experienced this moment sometime before, I’ve been here before. And actually there’s all sorts of variants of this. The French have all sorts of names for various versions of this, [foreign language 01:40:12]. I don’t know. It’s like all these different vus.

The French have all sorts of names for various versions of this, [foreign language 01:40:12]. I don’t know. It’s like all these different vus.
But deja vu is the sense that it can be almost disturbing intense sense of familiarity. So, there was a researcher named Wilder Penfield… Actually, this goes back even earlier to some of the earliest, like Hughlings Jackson was this neurologist who did a lot of the early characterizations of epilepsy. And one of the things he notices in epilepsy patients, some group of them right before they would get a seizure, they would have this intense sense of deja vu. So, it’s this artificial sense of familiarity, it’s a sense of having a memory that’s not there.
What was happening was there was electrical activity in certain parts of these brains, so the guy Penfield, later on when he was trying to look for how do we map out the brain to figure out which parts we want to remove and which parts don’t we, he would stimulate parts of the temporal lobes of the brain and find you could elicit the sense of deja vu. Sometimes you’d actually get a memory that a person would re-experience just from electrically stimulating some parts. Sometimes they just have this intense feeling of being somewhere before.
And so, one theory which I really like is that in higher order areas of the brain, they’re integrating from many, many different sources of input. What happens is that they’re tuning themselves up every time you process a similar input. And so that allows you to just get this kind of affluent sense that, “I’m very familiar…” You’re very familiar with this place. And so just being here, you’re not going to be moving your eyes all over the place because you kind of have an idea of where everything is. And that fluency gives you a sense of, “I’m here.”
Now, I wake up in my hotel room and I have this very unfamiliar sense of where I am. But there’s a great set of studies done by Anne Cleary at Colorado State where she created these virtual reality environments. And we’ll go back to the metaverse. Imagine you go through a virtual museum, and then she would put people in virtual reality and have them go through a virtual arcade. But the map of the two places was exactly the same. She just put different skins on them. So, one looks different than the other, but they’ve got same landmarks, and the same places, same objects, same everything, but carpeting, colors, theme, everything’s different.
People will often not have any conscious idea that the two are the same, but they could report this very intense sense of deja vu. So, it’s like a partial match that’s eliciting this kind of a sense of familiarity. And that’s why in patients who have epilepsy, that affects memory, you get this artificial sense of familiarity that happens.
And so we think that… And again, this is just one theory amongst many, but we think that we get a little bit of that feeling, it’s not enough to necessarily give you deja vu, even for very mundane things. So, it’s like if I tell you the word rutabaga, your brain’s going to work a little bit harder to catch it than if I give you word like apple. That’s because you hear apple a lot. So, your brain’s very tuned up to process it efficiently, but rutabaga takes a little bit longer and more intense. And you can actually see a difference in brain activity in areas in the temporal lobe when you hear a word just based on how frequent it is in the English language.
Lex Fridman
That’s fascinating.
That’s fascinating.
Charan Ranganath
We think it’s tied to this basic… It’s basically a by-product of our mechanism of just learning, doing this error-driven learning as we go through life to become better and better and better to process things more and more efficiently.

So, I guess deja vu is just thinking extra elevated, the stuff coming together, firing for this artificial memories, as if it’s the real memory. I mean, why does it feel so intense?

Charan Ranganath
Well, it doesn’t happen all the time, but I think what may be happening is it’s a partial match to something that we have, and it’s not enough to trigger that sense of… that ability to pull together all the pieces. But it’s a close enough match to give you that intense sense of familiarity, without the recollection of exactly what happened when.

But it’s also a spatio-temporal familiarity. So, it’s also in time. There’s a weird blending of time that happens, and we’ll probably talk about time because I think that’s a really interesting idea how time relates to memory. But you also kind of… Artificial memory brings to mind this idea of false memories that comes in all kinds of contexts. But how do false memories form?

False memories
Charan Ranganath
Well, I like to say there’s no such thing as true or false memories. It’s like Johnny Rotten from the Sex Pistols, he had a saying that’s like, “I don’t believe in false memories any more than I believe in false songs.” And so the basic idea is that we have these memories that reflect bits and pieces of what happened, as well as our inferences and theories.

So, I’m a scientist and I collect data, but I use theories to make sense of that data. And so, a memory is kind of a mix of all these things. Where memories can go off the deep end and become what we would call conventionally as false memories are sometimes little distortions where we filled in the blanks, the gaps in our memory, based on things that we know, but don’t actually correspond to what happened.
So, if I were to tell you that a story about this person who’s worried that they have cancer or something like that, and then they see a doctor and the doctor says, “Well, things are very much like you would’ve expected or what you were afraid of,” or something. When people remember that, they’ll often remember, “Well, the doctor told the patient that he had cancer.” Even if that wasn’t in the story because they’re infusing meaning into that story. So, that’s a minor distortion. But what happens is that sometimes things can really get out of hand where people have trouble telling the difference between things that they’ve imagined versus things that happen. But also, as I told you, the act of remembering can change the memory. And so what happens then is you can actually be exposed to some misinformation. And so Elizabeth Loftus was a real pioneer in this work, and there’s lots of other work that’s been done since.
But basically, it’s like if you remember some event, and then I tell you something about the event, later on, when you remember the event, you might remember some original information from the event as well as some information about what I told you. And sometimes, if you’re not able to tell the difference, that information that I told you gets mixed into the story that you had originally. So, now I give you some more misinformation or you’re exposed to some more information somewhere else, and eventually your memory becomes totally detached from what happened. And so sometimes you can have cases where people… This is very rare, but you can do it in lab too, or a significant… not everybody, but a chunk of people will fall for this, where you can give people misinformation about an event that never took place. And as they keep trying to remember that event more and more, what happens is they start to imagine, they start to pull up things from other experiences they’ve had, and eventually they can stitch together a vivid memory of something that never happened because they’re not remembering an event that happened. They’re remembering the act of trying to remember what happened, and basically putting it together into the wrong story.

It’s fascinating because this could probably happen at a collective level. This is probably what successful propaganda machines aim to do, this creating false memory across thousands, if not millions of minds.

Charan Ranganath
Yeah, absolutely. I mean, this is exactly what they do. And so, all these kind of foibles of human memory get magnified when you start to have social interactions. There’s a whole literature on something called social contagion, which is basically when misinformation spreads like a virus, like you remember the same thing that I did, but I give you a little bit of wrong information, then that becomes part of your story of what happened.

There’s a whole literature on something called social contagion, which is basically when misinformation spreads like a virus, like you remember the same thing that I did, but I give you a little bit of wrong information, then that becomes part of your story of what happened.
Because once you and I share a memory, I tell you about something I’ve experienced and you tell me about your experience at the same event, it’s no longer your memory or my memory, it’s our memory. And so now the misinformation spreads. And the more you trust someone or the more powerful that person is, the more of a voice they have in shaping that narrative.
And there’s all sorts of interesting ways in which misinformation can happen. There’s a great example of when John McCain and George Bush Jr. were in a primary, and there were these polls where they would do these, I guess they were not robocalls, but real calls where they would poll voters, but they actually inserted some misinformation about McCain’s beliefs on taxation, I think, or maybe it was something about illegitimate children or… I don’t really remember. But they included misinformation in the question that they asked, “How do you feel about the fact that he wants to do this?” Or something.
And so people would end up becoming convinced he had these policy things or these personal things that were not true, just based on the polls that were being used. So, it was a case where, interestingly enough, the people who were using misinformation were actually ahead of the curve relative to the scientists who were trying to study these effects in memory.
Lex Fridman
Yeah, it’s really interesting. So, it’s not just about truth and falsehoods, like us as intelligent, reasoning machines, but it’s the formation of memories where they become visceral. You can rewrite history.
Yeah, it’s really interesting. So, it’s not just about truth and falsehoods, like us as intelligent, reasoning machines, but it’s the formation of memories where they become visceral. You can rewrite history.
If you just look throughout the 20th century, some of the dictatorships with Nazi Germany, with the Soviet Union, effective propaganda machines can rewrite our conceptions of history, how we remember our own culture, our upbringing, all this kind of stuff. And you could do quite a lot of damage in this way. And then there’s probably some kind of social contagion happening there. Certain ideas that, maybe initiated by the propaganda machine, can spread faster than others.
You could see that in modern day, certain conspiracy theories, there’s just something about them that they are really effective at spreading. There’s something sexy about them to people to where something about the human mind eats it up and then uses that to construct memories as if they almost were there to witness whatever the content of the conspiracy theory is. It’s fascinating. Because you feel like you remember a thing, I feel like there’s a certainty. It emboldens you to say stuff. It’s not just you believe in ideas, true or not, it’s at the core of your being that you feel like you were there to watch the thing happen.
Charan Ranganath
Yeah, I mean there’s so much in what you’re saying. I mean, one of the things is that people’s sense of collective identity is very much tied to shared memories. If we have a shared narrative of the past, or even better, if we have a shared past, we will feel more socially connected with each other, and I will feel part of this group. They’re part of my tribe, if I remember the same things in the same way.

They’re part of my tribe, if I remember the same things in the same way.
And you brought up this weaponization of history, and it really speaks to, I think, one of the parts of memory, which is that if you have a belief, you will find, and you have a goal in mind, you’ll find stuff in memory that aligns with it, and you won’t see the parts in memory that don’t. So, a lot of the stories we put together are based on our perspectives.
And so let’s just zoom out for the moment from misinformation to take something even more fascinating, but not as scary. I was reading Thanh Viet Nguyen, but he wrote a book about the collective memory of the Vietnam War. He is a Vietnamese immigrant who was flown out after the war was over. And so he went back to his family to get their stories about the war, and they called it the American War, not the Vietnam War. And that just kind of blew my mind, having grown up in the US and having always heard about it as the Vietnam War. But of course they call it the American War, because that’s what happened. America came in. And that’s based on their perspective, which is a very valid perspective. And so that just gives you this idea of the way we put together these narratives based on our perspectives. And I think the opportunities that we can have in memory is if we bring groups together from different perspectives and we allow them to talk to each other and we allow ourselves to listen.
I mean, right now you’ll hear a lot of just jammering, people going, “Blah, blah, blah,” about free speech, but they just want to listen to themselves. I mean, it’s like, let’s face it, the old days before people were supposedly woke, they were trying to ban 2 Live Crew. Just think about Lenny Bruce got canceled for cursing. Jesus Christ. It’s like this is nothing new. People don’t like to hear things that disagree with them.
But if you’re in a… I mean, you can see two situations in groups with memory. One situation is you have people who are very dominant, who just take over the conversation. And basically what happens is the group remembers less from the experience and they remember more of what the dominant narrator says. Now, if you have a diverse group of people, and I don’t mean diverse in necessarily the human resource sense of the word, I mean diverse in any way you want to take it, but diverse in every way, hopefully. And you give everyone a chance to speak and everyone’s being appreciated for their unique contribution, you get more accurate memories and you get more information from it.
Even two people who come from very similar backgrounds, if you can appreciate the unique contributions that each one has, you can do a better job of generating information from memory. And that’s a way to inoculate ourselves, I believe, from misinformation in the modern world. But like everything else, it requires a certain tolerance for discomfort. And I think when we don’t have much time, and I think when we’re stressed out and when we are just tired, it’s very hard to tolerate discomfort.
Lex Fridman
And I mean, social media has a lot of opportunity for this because it enables this distributed one-on-one interaction that you’re talking about, where everybody has a voice, but still our natural inclination, you see this on social media, as there’s a natural clustering of people and opinions and you just form these kind of bubbles. To me personally, I think that’s a technology problem that could be solved if there’s a little bit of interaction, kind, respectful, compassionate interaction with people that have a very different memory, that respectful interaction will start to intermix the memories and ways of thinking to where you’re slowly moving towards truth. But that’s a technology problem because naturally, left our own devices, we want to cluster up in a tribe.

Charan Ranganath
Yeah, and that’s the human problem. I think a lot of the problems that come up with technology aren’t the technology itself, as much as the fact that people adapt to the technology in maladaptive ways. I mean, one of my fears about AI is not what AI will do, but what people will do. I mean, take text messaging. It’s a pain in the to text people, at least for me. And so what happens is the communication becomes very Spartan and devoid of meaning. It’s this very telegraphic. And that’s people adapting to the medium.

And so what happens is the communication becomes very Spartan and devoid of meaning. It’s this very telegraphic. And that’s people adapting to the medium.
I mean, look at you. You’ve got this keyboard that’s got these dome shaped things, and you’ve adapted to that to communicate. That’s not the technology adapting to you, that’s you adapting to the technology. And I think one of the things I learned when Google started to introduce autocomplete in emails, I started to use it. And about a third of the time I was like, “This isn’t what I want to say.” A third of the time, I’d be like, “This is exactly what I wanted to say.” And a third of the time I was saying, “Well, this is good enough. I’ll just go with it.”
And so what happens is it’s not that the technology necessarily is doing anything so bad, as much as it’s just going to constrain my language because I’m just doing suggested to me. And so this is why I say, kind of like my mantra for some of what I’ve learned about everything in memory, is to diversify your training data, basically, because otherwise you’re going to… So, humans have this capability to be so much more creative than anything generative AI will put together, at least right now, who knows where this goes? But it can also go the opposite direction where people could become much, much less creative, if they just become more and more resistant to discomfort and resistant to exposing themselves to novelty, to cognitive dissonance, and so forth.
Lex Fridman
I think there is a dance between natural human adaptation of technology and the people that design the engineering of that technology. So, I think there’s a lot of opportunity to create, like this keyboard, things that on net are a positive for human behavior. So, we adapt and all this kind of stuff. But when you look at the long arc of history across the years and decades, has humanity been flourishing? Are humans creating more awesome stuff, are humans happier? All that kind of stuff. And so there, I think technology, on net, has been, and I think, maybe hope, will always be, on net, a positive thing.

Charan Ranganath
Oh, life is getting better. But I don’t know that necessarily that attracts people’s happiness, right? I mean, I would argue that maybe, who knows, I don’t know this, but I wouldn’t be surprised if people in hunter-gatherer societies are happier. I mean, I wouldn’t be surprised if they’re happier than people who have access to modern medicine and email and cellphones.

Lex Fridman
Well, I don’t think there’s a question whether you take hunter-gatherer folks and put them into modern day and give them enough time to adapt, they would be much happier. The question is, in terms of every single problem they’ve had, is now solved. There’s now food, there’s guaranteed survival, and shelter and all this kind of stuff.

The question is, in terms of every single problem they’ve had, is now solved. There’s now food, there’s guaranteed survival, and shelter and all this kind of stuff.
So, what you’re asking is a deeper sort of biological question, do we want to be… Werner Herzog and the movie Happy People: Life in the Taiga, do we want to be busy 100% of our time hunting, gathering, surviving, worried about the next day? Maybe that constant struggle ultimately creates a more fulfilling life. I don’t know. But I do know this modern society allows us to, when we’re sick, to find medicine, to find cures, when we’re hungry, to get food, much more than we did even a hundred years ago. And there’s many more activities that you could perform, all creative, all these kinds of stuff that enables the flourishing of humans at the individual level.
Whether that leads to happiness, I mean, that’s a very deep philosophical question. Maybe struggle, deep struggle is necessary for happiness.
Charan Ranganath
Or maybe cultural connection. Maybe it’s about functioning in social groups that are meaningful, and having time. But I do think there’s an interesting memory related thing, which is that if you look at things like reinforcement learning for instance, you’re not learning necessarily every time you get a reward, if it’s the same reward, you’re not learning that much. You mainly learn if it deviates from your expectation of what you’re supposed to get.

You mainly learn if it deviates from your expectation of what you’re supposed to get.
So, it’s like you get a paycheck every month from MIT or whatever, and you probably don’t even get excited about it when you get the paycheck. But if they cut your salary, you’re going to be pissed. And if they increase your salary, “Oh good, I got a bonus.” And that adaptation and that ability that basically you learn to expect these things, I think, is a major source of… I guess it’s a major way in which we’re kind of more, in my opinion, wired to strive and not be happy, to be in a state of wanting.
And so people talk about dopamine, for instance, being this pleasure chemical. And there’s a lot of compelling research to suggest it’s not about pleasure at all. It’s about the discomfort that energizes you to get things, to seek a reward. And so you could give an animal that’s been deprived of dopamine a reward and, “Oh yeah, I enjoy it. It’s pretty good.” But they’re not going to do anything to get it.
And just one of the weird things in our research is I got into curiosity from a postdoc in my lab, Matthias Gruber, and one of the things that we found is when we gave people a question, like a trivia question that they wanted the answer to, that question, the more curious people were about the answer, the more activity in these dopamine-related circuits in the brain, we would see. And again, that was not driven by the answer per se, but by the question.
So, it was not about getting the information, it was about the drive to seek the information. But it depends on how you take that. If you get this uncomfortable gap between what you know and what you want to know, you could either use that to motivate you and energize you, or you could use it to say, “I don’t want to hear about this. This disagrees with my beliefs. I’m going to go back to my echo chamber.”
Lex Fridman
Yeah, I like what you said that maybe we’re designed to be in a kind of constant state of wanting, which by the way, is a pretty good either band name or rock song name, state of wanting.

We could build a false memory of a show, in fact, if you want. Let’s just put it all together so we don’t even have to do all the work to play the show. We can just create a memory of it and it might as well happen because the remembering itself is in charge anyway.

False confessions
Lex Fridman
So, let me ask you about… We talked about false memories, but in the legal system, false confessions. I remember reading 1984 where, sorry for the dark turn of our conversation, but through torture, you can make people say anything and essentially remember anything. I wonder to which degree, there’s truth to that, if you look at the torture that happened in the Soviet Union, for confessions, all that kind of stuff. How much can you really get people to force false memories, I guess?

Charan Ranganath
Yeah. I mean, I think there’s a lot of history of this actually, in the criminal justice system. You might’ve heard the term “the third degree.” If you actually look it up historically, it was a very intense set of beatings and starvation and physical demands that they would place at people to get them to talk. And there’s certainly a lot of work that’s been done by the CIA in terms of enhanced interrogation techniques.

And there’s certainly a lot of work that’s been done by the CIA in terms of enhanced interrogation techniques.
And from what I understand, the research actually shows that they just produce what people want to hear, not necessarily the information that is being looked for. And the reason is that… I mean, there’s different reasons. One is people just get tired of being tortured and just say whatever. But another part of it is that you create a very interesting set of conditions where there’s an authority figure telling you something that, “You did this, we know you did this. We have witnesses saying you did this.”
So, now you start to question yourself. Then they put you under stress. Maybe they’re not feeding you, maybe they’re making you be cold or exposing you to music that you can’t stand or something, whatever it is, right? It’s like they’re creating this physical stress. And so stress starts to down-regulate the prefrontal cortex. You’re not necessarily as good at monitoring the accuracy of stuff. Then they start to get nice to you and they say, “Imagine, okay, I know you don’t remember this, but maybe we can walk you through how it could have happened.” And they feed you the information.
And so you’re in this weakened mental state, and you’re being encouraged to imagine things by people who give you a plausible scenario. And at some point, certain people can be very coaxed into creating a memory for something that never happened. And there’s actually some pretty convincing cases out there where you don’t know exactly the truth.
There’s a sheriff, for instance, who came to believe that he had a false memory… I mean, that he had a memory of doing sexual abuse based on essentially, I think it was… I’m not going to tell the story because I don’t remember it well enough to necessarily accurately give it to you, but people could look this stuff up. There are definitely stories out there like this where people confess to crimes that they just didn’t do, and-
Charan Ranganath
… out there like this, where people confess to crimes that they just didn’t do and objective evidence came out later on. There’s a basic recipe for it, which is you feed people the information that you want them to remember, you stress them out. You have an authority figure pushing this information on them, or you motivate them to produce the information you’re looking for. That pretty much over time gives you what you want.

Heartbreak
Lex Fridman
It’s really tragic that centralized power can use these kinds of tools to destroy lives. Sad. Since there’s a theme about music throughout this conversation, one of the best topics for songs is heartbreak. Love in general, but heartbreak. Why and how do we remember and forget heartbreak? Asking for a friend.

Asking for a friend.
Charan Ranganath
Oh, God, that’s so hard to… Asking for a friend. I love that. It’s such a hard one. Part of this is we tend to go back to particular times that are the more emotionally intense periods, and so that’s a part of it. Again, memory is designed to capture these things that are biologically significant, and attachment is a big part of biological significance for humans. Human relationships are super important and sometimes that heartbreak comes with massive changes in your beliefs about somebody say if they cheated on you or something like that, or regrets and you kind of ruminate about things that you’ve done wrong.

Human relationships are super important and sometimes that heartbreak comes with massive changes in your beliefs about somebody say if they cheated on you or something like that, or regrets and you kind of ruminate about things that you’ve done wrong.
There’s really so many reasons though, but I’ve had this. My first pet I had, we got it for a wedding present. It was a cat. Got it after, but it died of FIP when it was four years old. I just would see her everywhere around the house. We got another cat, then we got a dog. Dog eventually died of cancer, and the cat just died recently. So we got a new dog because I kept seeing the dog around and I was just so heartbroken about this, but I still remember the pets that died. It just comes back to you. I mean, it’s part of this. I think there’s also something about attachment that’s just so crucial that drives again, these things that we want to remember and that gives us that longing sometimes. Sometimes it’s also not just about the heartbreak, but about the positive aspects of it.
The loss comes from not only the fact that the relationship is over, but you had all of these good things before that you can now see in a new light. Part of one of the things that I found from my clinical background that really I think gave me a different perspective on memory is so much of the therapy process was guided towards reframing and getting people to look at the past in a different way, not by imposing changing people’s memories or not by imposing an interpretation, but just offering a different perspective and maybe one that’s kind of more optimized towards learning and an appreciation maybe, or gratitude, whatever it is that gives you a way of taking…
I think you said it in the beginning, right? Where you can have this kind of dark experiences and you can use it as training data to grow in new ways, but it’s hard.
Lex Fridman
I often go back to this moment, this show Louis with Louis CK, where he’s all heartbroken about a breakup with a woman he loves, and an older gentleman tells him that that’s actually the best part, that heartbreak, because you get to intensely experience how valuable this love was. He says the worst part is forgetting it. It is actually when you get over the heartbreak, that’s the worst part. I sometimes think about that because having the love and losing it, the losing it is when you sometimes feel it the deepest, which is an interesting way to celebrate the past and relive it.

It sucks that you don’t have a thing, but when you don’t have a thing, it’s a good moment to viscerally experience the memories of something that you now appreciate even more.

Well, it’s funny because it’s like after I turned 50, I think of death all the time. I just think that I have probably a fewer years ahead of me than I’m behind me. I think about one thing, which is what are the memories that I want to carry with me for the next period of time? And also, about just the fact that everything around me could be… I know more people who are dying for various reasons. I’m not Lot. I’m not that old, but it’s something I think about a lot. I’m reminded of how I talked to somebody who’s a Buddhist and I was like, “The whole of Buddhism is renouncing attachment.”

I’m reminded of how I talked to somebody who’s a Buddhist and I was like, “The whole of Buddhism is renouncing attachment.”
In some way, the idea of Buddhism is like staying out of the world of memory and staying in the moment. They talked about how do you renounce attachments to the people that you love? They’re just saying, “Well, I appreciate that I have this moment with them and knowing that they will die makes me appreciate this moment that much more.” You said something similar in your daily routine that you think about things this way, right?
Lex Fridman
Yeah, I meditate on mortality every day, but I don’t know, at the same time, that really makes you appreciate the moment and live in the moment. I also appreciate the full deep rollercoaster of suffering involved in life, the little and the big too. I don’t know. The Buddhist removing yourself from the world or the Stoic removing yourself from the world, the world of emotion, I’m torn about that one. I’m not sure.

The Buddhist removing yourself from the world or the Stoic removing yourself from the world, the world of emotion, I’m torn about that one. I’m not sure.
Charan Ranganath
This is where Hinduism and Buddhism, or at least some strains of Hinduism and Buddhism, differ. Hinduism, if you read the Bhagavad Gita, the philosophy is not one of renouncing the world because the idea is that not doing something is no different than doing something. What they argue, and again, you could interpret in different ways, positive and negative, but the argument is that you don’t want to renounce action, but you want to renounce the fruits of the action. You don’t do it because of the outcome. You do it because of the process, because the process is part of the balance of the world that you’re trying to preserve. Of course you could take that different ways, but I really think about that from time to time in terms of letting go of this idea of does this book sell or trying to impress you and get you to laugh at my jokes or whatever, and just be more like I’m sharing this information with you and getting to know you or whatever it is. It’s hard, because we’re so driven by the reinforcer, the outcome.

Nature of time
Lex Fridman
How does studying memory affect your understanding of the nature of time? We’ve been talking about us living in the present and making decisions about the future, standing on the foundation of these memories and narratives about the memories that we’ve constructed. It feels like it does weird things to time.

Charan Ranganath
Yeah, and the reason is that in some sense, I think especially the farther we go back, there’s all sorts of interesting things that happen. Your sense of if I ask how different does one hour ago feel from two hours ago? You’d probably say pretty different. But if I ask you, okay, go back one year ago versus one year and one hour ago, it’s the same difference in time. It won’t feel very different. There’s this kind of compression that happens as you look back farther in time.

There’s this kind of compression that happens as you look back farther in time.
It is kind of like why when you’re older, the difference between somebody who’s 50 and 45 doesn’t seem as big as the difference between 10 and five or something. When you’re 10 years old, everything seems like it’s a long period of time. Here’s the point is that… One of the interesting things that I found when I was working on the book actually was during the pandemic, I just decided to ask people in my class when we were doing the remote instruction. One of the things I did was I would pull people. I just asked people, “Do you feel like the days are moving by slower or faster or about the same?”
Almost everyone in the class said that the days were moving by slower. Then I would say, “Okay, so do you feel like the weeks are passing by slower, faster, or the same?” The majority of them said that the weeks were passing by faster. According to the laws of physics, I don’t think that makes any sense, but according to memory, it did because what happened was people were doing the same thing over and over in the same context. Without that change in context, their feeling was that they were in one long monotonous event.
Then at the end of the week, you look back at that week and you say, “Well, what happened? I have no memories of what happened,” so the week just went by without even my noticing it. That week went by during the same amount of time as an eventful week where you might’ve been going out hanging out with friends on vacation or whatever. It’s just that nothing happened because you’re doing the same thing over and over. I feel like memory really shapes our sense of time, but it does so in part because context is so important for memory.
Lex Fridman
That compression you mentioned, it’s an interesting process because when I think about when I was 12 or 15, I just fundamentally feel like the same person. It’s interesting what that compression does. It makes me feel like we’re all connected, not just amongst humans and spatially, but in terms back in time. There’s a kind of eternal nature, like the timelessness I guess, to life. That could be also a genetic thing just for me. I don’t know if everyone agrees to this view of time, but to me it all feels the same.

Lex Fridman
No, I feel the passage of time in the same way that your students did from day to day. There’s certain markers that let you know that time has passed, you celebrate birthdays and so on, but the core of who I am and who others I know are, or events, that compression of my understanding of the world removes time because time is not useful for the compression. The details of that time, at least for me, is not useful to understanding the core of the thing.

Maybe what it is that you really like to see connections between things. This is really what motivates me in science actually too. It’s like when you start recalling the past and seeing the connections between the past and present, now you have this web of interconnected memories. I can imagine in that sense there is this kind of the present is with you. What’s interesting about what you said too that struck me is that your 16-year-old self was probably very complex.

By the way, I’m the same way, but it’s like it really is the source of a lot of darkness for me. When you can look back at, let’s say you hear a song that you used to play before you would go do a sports thing or something like that, you might not think of yourself as an athlete, but once you mentally time travel to that particular thing, you open up this little compartment of yourself that wasn’t there before that didn’t seem accessible before. Dan Schacter’s lab did this really cool study where they would ask people to either remember doing something altruistic or imagine doing something altruistic, and that act made them more likely to want to do things for other people.
That act of mental time travel can change who you are in the present. We tend to think of, this goes back to that illusion of stability, and we tend to think of memory in this very deterministic way that I am who I am because I have this past, but we have a very multi-faceted past and can access different parts of it and change in the moment based on whatever part we want to reach for.

How does nostalgia connect into this desire and pleasure associated with going back?
How does nostalgia connect into this desire and pleasure associated with going back?
Charan Ranganath
My friend Felipe de Brigard wrote this, and it just blew my mind, where the word nostalgia was coined by a Swiss physician who was actually studying traumatized soldiers. He described nostalgia as a disease. The idea was it was bringing these people extraordinary unhappiness because they’re remembering how things used to be. I think it’s very complex. As people get older, for instance, nostalgia can be an enormous source of happiness. Being nostalgic can improve people’s moods in the moment, but it just depends on what they do with it because what you can sometimes see is nostalgia has the opposite effect of thinking those were the good old days, and those days are over.

It’s like America used to be so great, and now it sucks. My life used to be so great when I was a kid and now it’s not. You’re selectively remembering the things that… I mean, we don’t realize how selective our remembering self is. I lived through the 70s. It sucked. Partly it sucked more for me, but I would say that even otherwise, it’s like there’s all sorts of problems going on, gas lines, people were worried about Russia, nuclear war, blah, blah, blah. It’s just this idea that people have about the past can be very useful if it brings you happiness in the present, but if it narrows your worldview in the present, you’re not aware of those biases that you have, it can be toxic either at a personal level or at a collective level.
Brain–computer interface (BCI)
Lex Fridman
Let me ask you both a practical question and an out there question. Let’s start with a more practical one. What are your thoughts about BCIs, brain computer interfaces, and the work that’s going on with Neuralink? We talked about electrodes and different ways of measuring the brain, and here Neuralink is working on basically two-way communication with the brain. The more out there question will be like, where’s this go? More practically in the near term, what do you think about Neuralink?

I can’t say specifics about the company because I haven’t studied it that much, but I think there’s two parts of it. One is, they’re developing some really interesting technology I think with these surgical robots and things like that. BCI though has a whole lot of innovation going on. I am not necessarily seeing any scientific evidence from Neuralink, and maybe that’s just because I’m not looking for it, but I’m not seeing the evidence that they’re anywhere near where the scientific community is. There’s lots of startups that are doing incredibly innovative stuff.

There’s lots of startups that are doing incredibly innovative stuff.
One of my colleagues, Sergey Stavisky is just a genius in this area, and they’re working on it. I think speech prosthetics like they’re incorporating, decoding techniques with AI and movement prosthetics. This is just the rate of progress is just enormous. Part of the technology is having good enough data and understanding which data to use and what to do with it. Then the other part of it then is the algorithms for decoding it and so forth. I think part of that has really resulted in some real breakthroughs in neuroscience as a result. There’s lots of new technologies like Neuropixels for instance, that allow you to harvest activity from many, many neurons from a single electrode.
I know Neuralink has some technologies that are also along these lines, but again, because they do their own stuff, the scientific community doesn’t see it. I think BCI is much, much bigger than Neuralink and there’s just so much innovation happening. I think the interesting question which we may be getting into is, I was talking to Sergey a while ago about a lot of language is not just what we hear and what we speak, but also our intentions and our internal models. And so, are you really going to be able to restore language without dealing with that part of it?
He brought up a really interesting question, which is the ethics of reading out people’s intentions and understanding of the world as opposed to the more concrete parts of hearing and producing movements.
Lex Fridman
Just so we’re clear, because you said a few interesting things, when we talk about language and BCIs, what we mean is getting signal from the brain and generating the language, say you’re not able to actually speak, it’s as a kind of linguistic prosthetic. It’s able to speak for you exactly what you want it to say. Then the deeper question is, well, saying something isn’t just the letters, the words that you’re saying, it’s also the intention behind it, the feeling behind all that kind of stuff.

Is it ethical to reveal that full shebang, the full context of what’s going on in our brain? That’s really interesting. That’s really interesting. Our thoughts, is it ethical for anyone to have access to our thoughts? Because right now the resolution is so low that we’re okay with it, even doing studies and all this kind of stuff. If neuroscience has a few breakthroughs to where you can start to map out the QR codes for different thoughts, for different kinds of thoughts, maybe political thoughts, the McCarthyism, what if I’m getting a lot of them communist thoughts, or however we want to categorize or label it? That’s interesting.
That’s really interesting. I think ultimately this always… The more transparency there is about the human mind, the better it is. There could be always intermediate battles with how much control does a centralized entity have, like a government and so on. What is the regulation? What are the rules? What’s legal and illegal? If you talk about the police, whose job is to track down criminals and so on, and you look at all the history, how the police could abuse its power to control the citizenry, all that kind of stuff. People are always paranoid and rightfully so. It’s fascinating. It’s really fascinating.
We talk about freedom of speech, freedom of thought, which is also a very important liberty at the core of this country and probably humanity. It starts to get awfully tricky when you start to be able to collect those thoughts. What I wanted to actually ask you is do you think for fun and for practical purposes, we would be able to modify memories? How far away we are from understanding the different parts of the brains, everything we’ve been talking about, in order to figure out how can we adjust this memory at the crude level from unpleasant to pleasant?
You talked about we can remember the mall and the location, the people. Can we keep the people and change the place? This kind of stuff, how difficult is that?
Charan Ranganath
In some sense we know we can do it, just behaviorally.

Charan Ranganath
I can just tell you under certain conditions anyway, it can give you the misinformation and then you can change the people, the places and so forth. On the crude level, there’s a lot of work that’s being done on a phenomenon called reconsolidation, which is the idea that essentially when I recall a memory, what happens is that the connections between the neurons and that cell assembly that give you the memory are going to be more modifiable. Some people have used techniques to try to, for instance, with fear memories, to reduce that physical visceral component of the memory when it’s being activated.

Some people have used techniques to try to, for instance, with fear memories, to reduce that physical visceral component of the memory when it’s being activated.
Right now, I think as an outsider looking at the data, I think it’s mixed results. Part of it is, and this speaks to the more complex issue, is that you need somebody to actually fully recall that traumatic memory in the first place. In order to actually modify it, then what is the memory? That is the key part of the problem. If we go back to reading people’s thoughts, what is the thought? People can sometimes look at us like behaviorists and go, “Well, the memory is like I’ve given you A and you produce B,” but I think that’s a very bankrupt concept about memory. I think it’s much more complicated than that.
One of the things that when we started studying naturalistic memory, like memory from movies, that was so hard was we had to change the way we did the studies. If I show you a movie and I watched the same movie and you recall everything that happened, and I recall everything that happened, we might take a different amount of time to do it. We might use different words. And yet, to an outside observer, we might’ve recalled the same thing. It’s not about the words necessarily, and it’s not about how long we spent or whatever.
There’s something deeper that is there that’s this idea, but it’s like, how do you understand that thought? I encounter a lot of concrete thinking that it’s like if I show a model, like the visual information that a person sees when they drive, I can basically reverse engineer driving. Well, that’s not really how it works. I once saw somebody talking in this discussion between neuroscientists and AI people, and he was saying that the problem with self-driving cars that they had in cities as opposed to highways was that the car was okay at doing the things it’s supposed to, but when there were pedestrians around, it couldn’t predict the intentions of people.
And so, that unpredictability of people was the problem that they were having in the self-driving car design. It didn’t have a good enough internal model of what the people were, what they were doing, what they wanted. What do you think about that?
Lex Fridman
I spent a huge amount of time watching pedestrians, thinking about pedestrians, thinking about what it takes to solve the problem of measuring, detecting the intention of a pedestrian, really, of a human being in this particular context of having to cross the street. It’s fascinating. I think it’s a window into how complex social systems are that involve humans. I would just stand there and watch intersections for hours. What you start to figure out is every single intersection has its own personality.

It’s fascinating. I think it’s a window into how complex social systems are that involve humans. I would just stand there and watch intersections for hours. What you start to figure out is every single intersection has its own personality.
There’s a history to that intersection, like jaywalking, certain intersections allow jaywalking a lot more because what happens is we’re leaders and followers, so there’s a regular, let’s say, and they get off the subway and they start crossing on a red light, and they do this every single day. Then there’s people that don’t show up to that intersection often, and they’re looking for cues of how we’re supposed to behave here. If a few people start to jaywalk and cross on a red light, they will also. They will follow. There’s just a dynamic to that intersection. There’s a spirit to it.
If you look at Boston versus New York versus a rural town versus even Boston, San Francisco or here in Austin, there’s different personalities city-wide, but there’s different personalities area-wise, region-wise, and there’s different personalities at different intersections. It’s just fascinating. For a car to be able to determine that, it’s tricky. Now, what machine learning systems are able to do well is collect a huge amount of data. For us, it’s tricky because we get to understand the world with very limited information and make decisions grounded in this big foundation model that we’ve built of understanding how humans work. AI could literally, in the context of driving, this is where I’ve often been really torn in both directions. If you just collect a huge amount of data, all of that information, and then compress it into a representation of how humans cross streets, it’s probably all there. In the same way that you have a Noam Chomsky who says, “No, no, no, AI can’t talk, can’t write convincing language without understanding language.” More and more you see large language models without “understanding” can generate very convincing language.
I think what the process of compression from a huge amount of data compressing into a representation is doing is in fact understanding deeply. In order to be able to generate one letter at a time, one word at a time, you have to understand the cruelty of Nazi Germany and the beauty of sending humans to space. You have to understand all of that in order to generate, “I’m going to the kitchen to get an apple,” and do that grammatically correctly. You have to have a world model that includes all of human behavior.
Charan Ranganath
You’re thinking LLM is building that world model.
You’re thinking LLM is building that world model.

It has to in order to be good at generating one word at a time, a convincing sentence. In the same way, I think AI that drives a car, if it has enough data, will be able to form a world model that will be able to predict correctly what a pedestrian does. When we as humans are watching pedestrians, we slowly realize, damn, this is really complicated. In fact, when you start to self-reflect on driving, you realize driving is really complicated. There’s subtle cues we take about just… This is a million things I could say, but one of them, determining who around you is an asshole, aggressive driver, potentially dangerous.

I don’t know what… Because we’re ignoring all the other cars, but for some reason, the asshole, like a glowing obvious symbol is just right there, even in the periphery vision because again, we’re usually when we’re driving just looking forward, but we’re using the periphery vision to figure stuff out. It’s a little puzzle that we’re usually only allocating a small amount of our attention to, at least cognitive attention to. It’s fascinating, but I think AI just has a fundamentally different suite of sensors in terms of the bandwidth of data that’s coming in that allows you to form the representation that perform inference on using the representation you form.

AI and memory
For the case of driving, I think it could be quite effective. One of the things that’s currently missing, even though OpenAI just recently announced adding memory, and I did want to ask you how important it is, how difficult is it to add some of the memory mechanisms that you’ve seen in humans to AI systems?
Charan Ranganath
I would say superficially not that hard, but then in a deeper level, very, very hard because we don’t understand episodic memory. One of the ideas I talk about in the book, because one of the oldest dilemmas in computational neurosciences, what Steve Grossberg called the Stability Plasticity Dilemma, when do you say something is new and overwrite your preexisting knowledge versus going with what you had before and making incremental changes? Part of the problem with going through massive… Part of the problem of things like if you’re trying to design an LLM or something like that, is, especially for English, there’s so many exceptions to the rules. If you want to rapidly learn the exceptions, you’re going to lose the rules, and if you want to keep the rules, you have a harder time learning the exception. David Marr is one of the early pioneers in computational neuroscience, and then Jay McClellan and my colleague, Randy O’Reilly, some other people like Neil Cohen, all these people started to come up with the idea that maybe that’s part of what we need.

What the human brain is doing is we have this kind of actually a fairly dumb system, which just says, “This happened once at this point in time,” which we call episodic memory, so to speak. Then we have this knowledge that we’ve accumulated from our experiences of semantic memory. Now when we encounter a situation that’s surprising and violates all our previous expectations, what happens is that now we can form an episodic-
Charan Ranganath
… expectations. What happens is that now we can form an episodic memory here, and the next time we’re in a similar situation, boom. We can supplement our knowledge with this information from episodic memory and reason about what the right thing to do is. So it gives us this enormous amount of flexibility to stop on a dime and change, without having to erase everything we’ve already learned. And that solution is incredibly powerful, because it gives you the ability to learn from so much less information, really, and it gives you that flexibility. So one of the things I think that makes humans great is having both episodic and semantic memory. Now, can you build something like that? Computational neuroscience, people would say, “Well, yeah, you just record a moment and you just get it, and you’re done.” But when do you record that moment? How much do you record? What’s the information you prioritize and what’s the information you don’t?

These are the hard questions. When do you use episodic memory? When do you just throw it away? These are the hard questions we’re still trying to figure out in people. Then you start to think about all these mechanisms that we have in the brain for figuring out some of these things. And it’s not just one, but it’s many of them that are interacting with each other. And then you just take not only the episodic and the semantic, but then you start to take the motivational survival things, right? It’s just like the fight-or-flight responses that we associate with particular things, or the reward motivation that we associate with certain things, so forth.
And those things are absent from AI. I frankly don’t know if we want it. I don’t necessarily want a self-motivated LLM, right? It’s like, and then there’s the problem of how do you even build the motivations that should guide a proper reinforcement learning kind of thing, for instance. So a friend of mine, Sam Gershman, I might be missing the quote exactly, but he basically said, “If I wanted to train a typical AI model to make me as much money as possible, first thing I might do is sell my house.” So it’s not even just about having one goal or one objective, but just having all these competing goals and objectives, and then things start to get really complicated.
Lex Fridman
Well, it’s all interconnected. I mean, just even the thing you’ve mentioned is the moment, if we record a moment, it is difficult to express concretely what a moment is, how deeply connected it’s to the entirety of it. Maybe to record a moment, you have to make a universe from scratch. You have to include everything. You have to include all the emotions involved, all the context, all the things that built around it, all the social connections, all the visual experiences, all the sensory experience, all of that, all the history that came before that moment is built on. And we somehow take all of that and we compress it, and keep the useful parts and then integrate it into the whole thing, into our whole narrative. And then each individual has their own little version of that narrative, and then we collide in a social way, and we adjust it. And we evolve.

Charan Ranganath
Yeah. Yeah. I mean, well, even if we want to go super simple, like Tyler Bonin, who’s a postdoc, who’s collaborating with me, he actually studied a lot of computer vision at Stanford. And so, one of the things he was interested in is some people who have brain damage in areas of the brain that were thought to be important for memory, but they also seem to have some perception problems with particular kinds of object perception. And this is super controversial, and some people found this effect, some didn’t. And he went back to computer vision and he said, “Let’s take the best state-of-the-art computer vision models, and let’s give them the same kinds of perception tests that we were giving to these people.” And then he would find the images where the computer vision models would just struggle, and you’d find that they just didn’t do well. Even if you add more parameters, you add more layers on and on and on. It doesn’t help. The architecture didn’t matter. It was just there, the problem.

Even if you add more parameters, you add more layers on and on and on. It doesn’t help. The architecture didn’t matter. It was just there, the problem.
And then, he found those were the exact ones where these humans with particular damage to this area called the perirhinal cortex, that was where they were struggling. So somehow this brain area was important for being able to do these things that were adversarial to these computer vision models. So then he found that it only happened if people had enough time, they could make those discriminations, but without enough time if they just get a glance, they’re just like the computer vision models. So then what he started to say was, “Well, maybe let’s look at people’s eyes.”
So computer vision model sees every pixel all at once, and we don’t, we never see every pixel all at once. Even if I’m looking at a screen with pixels, I’m not seeing every pixel at once. I’m grabbing little points on the screen by moving my eyes around, and getting a very high resolution picture of what I’m focusing on, and kind of a lower resolution information about everything else. But I’m not necessarily choosing, but I’m directing that exploration, and allowing people to move their eyes and integrate that information gave them something that the computer vision models weren’t able to do. So somehow integrating information across time and getting less information at each step gave you more out of the process.
Lex Fridman
The process of allocating attention across time seems to be a really important process. Even the breakthroughs that you get with machine learning mostly has to do attention is all you need, is about attention. Transform is about attention. So attention is a really interesting one. But then, yeah, how you allocate that attention, again is at the core of what it means to be intelligent, what it means to process the world, integrate all the important things, discard all the unimportant things.

But then, yeah, how you allocate that attention, again is at the core of what it means to be intelligent, what it means to process the world, integrate all the important things, discard all the unimportant things.
Attention is at the core of it, it’s probably at the core of memory too. There’s so much sensory information. There’s so much going on, there’s so much going on. To filter it down to almost nothing and just keep those parts, and to keep those parts, and then whenever there’s an error to adjust the model, such that you can allocate attention even better to new things that would resolve, maybe maximize the chance of confirming the model, or disconfirming the model that you have, and adjusting it since then. Yeah, attention is a weird one. I was always fascinated. I mean, I got a chance to study peripheral vision for a bit and indirectly study attention through that. And it’s just fascinating how good humans are looking around and gathering information.
Charan Ranganath
Yeah. At the same time. People are terrible at detecting changes that can happen in the environment if they’re not attending in the right way, if their predictive model is too strong. So you have these weird things where the machines can do better than the people. It’s not that it’s like, so this is the thing, is people go, “Oh, the machines can do this stuff that’s just like humans.”

It’s like, well, the machines make different kinds of mistakes than the people do, and I will never be convinced unless we’ve replicated human. I don’t even like the term intelligence. I think it is a stupid concept, but I don’t think we’ve replicated human intelligence, unless I know that the simulator is making exactly the same kinds of mistakes that people do, because people make characteristic mistakes. They have characteristic biases, they have characteristic heuristics that we use, and those have yet to see evidence that ChatGPT will do that.
ADHD
Lex Fridman
Since we’re talking about attention, is there an interesting connection to you between ADHD and memory?
Since we’re talking about attention, is there an interesting connection to you between ADHD and memory?
Charan Ranganath
Well, it’s interesting for me, because when I was a child, I was actually told, my school, I don’t know if it came from a school psychologist, they did do some testing on me, I know for IQ and stuff like that, or if it just came from teachers who hated me, but they told my parents that I had ADHD. And so, this was of course in the ’70s. So basically they said, “He has poor motor control and he’s got ADHD,” and there was social issues, so I could have been put a year ahead in school. But then they said, “Oh, but he doesn’t have the social capabilities.” So I still ended up being an outcast even in my own grade.

But then they said, “Oh, but he doesn’t have the social capabilities.” So I still ended up being an outcast even in my own grade.
So then my parents said, okay, well, they got me on a diet free of artificial colors and flavors, because that was the thing that people talked about back then. I’m interested this topic, because I’ve come to appreciate now that I have many of the characteristics, if not full-blown, it’s like I’m definitely, timeline is a rejection since you name it, they talk about it. It’s like impulsive behavior. I can tell you about all sorts of fights I’ve gotten into in the past, just you name it. But yeah, so ADHD is fascinating though, because right now we’re seeing more and more diagnosis of it, and I don’t know what to say about that. I don’t know how much of that is based on inappropriate expectations, especially for children and how much of that is based on true maladaptive kinds of tendencies.
But what we do know is this, is that ADHD is associated with differences in prefrontal function, so that attention can be both more, you’re more distractible, you have harder time focusing your attention on what’s relevant, and so you shift too easily. But then, once you get on something that you’re interested in, you can get stuck. And so, the attention is this beautiful balance of being able to focus when you need to focus, and shift when you need to shift. And so it’s that flexibility plus stability again, and that’s balance seems to be disrupted in ADHD. And so, as a result, memory tends to be poor in ADHD, but it’s not necessarily because there’s a traditional memory problem, but it’s more because of this attentional issue. And people with ADHD often will have great memory for the things that they’re interested in, and just no memory for the things that they’re not interested in.
Lex Fridman
Is there advice from your own life on how to learn and succeed from that? From just how the characteristics of your own brain with ADHD and so on, how do you learn, how do you remember information? How do you flourish in this sort of education context?

Charan Ranganath
I’m still trying to figure out the flourishing per se, but education, I mean, being in science is enormously enabling of ADHD. It’s like you’re constantly looking for new things. You’re constantly seeking that dopamine hit, and that’s great. They tolerate your being late for things. Nobody’s going to die if you screw up. It’s nice. It’s not like being a doctor or something where you have to be much more responsible and focused. You could just freely follow your curiosity, which is just great. But what I’d say is that I’m learning now about so many things, like about how to structure my activities more and basically say, okay, if I’m going to be… Email is the big one that kills me right now, I’m just constantly shifting between email and my activities. And what happens is that I don’t actually get the email. I just look at my email and I get stressed, because I’m like, oh, I have to think about this.

Let me get back to it. And I go back to something else. And so, I’ve just got fragmentary memories of everything. So what I’m trying to do is set aside a timer. This is my email time, this is my writing time, this is my goofing off time. And so, blocking these things off, you give yourself the goofing off time. Sometimes I do that and sometimes I have to be flexible, and go like, okay, I’m definitely not focusing. I’m going to give myself the down time, and it’s an investment. It’s not like wasting time. It’s an investment in my attention later on.
Lex Fridman
And I’m very much with Cal Newport on this. He wrote Deep Work and a lot of other amazing books. He talks about task switching as the thing that really destroys productivity. So switching, it doesn’t even matter from what to what, but checking social media, checking email, maybe switching to a phone call, and then doing work and then switching. Even switching between if you’re reading a paper, switching from paper to paper to paper, because curiosity and whatever the dopamine hit from the attention switch, limiting that, because otherwise your brain is just not capable to really load it in, and really do that deep deliberation I think that’s required to remember things, and to really think through things.

Charan Ranganath
Yeah, I mean, you probably see this, I imagine in AI conferences, but definitely in neuroscience conferences, it’s now the norm that people have their laptops out during talks, and conceivably they’re writing notes. But in fact, what often happens if you look at people, and we can speak from a little bit of personal experience, is you’re checking email, or I’m working on my own talk. But often, it’s like you’re doing things that are not paying attention, and I have this illusion, well, I’m paying attention and then I’m going back.

But often, it’s like you’re doing things that are not paying attention, and I have this illusion, well, I’m paying attention and then I’m going back.
And then, what happens is I don’t remember anything from that day. It just kind of vanished, because what happens, I’m creating all these artificial event boundaries. I’m losing all this executive function every time I switch, I’m getting a few seconds slower and I’m catching up mentally to what’s happening. And so, instead of being in a model where you’re meaningfully integrating everything and predicting and generating this kind of rich model, I’m just catching up. And so yeah, there’s great research by Melina Uncapher and Anthony Wagner on multitasking, that people can look up that talks about just how bad it is for memory, and it’s becoming worse and worse of a problem.
Music
Lex Fridman
So you’re a musician. Take me through how’d you get into music? What made you first fall in love with music, with creating music?

Yeah, so basically in high school. So I kind of was a late bloomer to music, but just kind of MTV grew up with me. I grew up with MTV.
And so, then you started seeing all this stuff. And then, I got into metal was kind of my early genre, and I always reacted to just things that were loud and had a beat. I mean, ADHD, right? It’s like everything from Sergeant Pepper by the Beatles to Led Zeppelin II. My dad had, both my parents had both those albums, so I listened to them a lot. And then, the Police, Ghost in the Machine. But then I got into metal Def Leppard, and AC/DC, Metallica. Went way down the rabbit hole of speed metal. And that time was kind of like, oh, why don’t I play guitar? I can do this. And I had friends who were doing that, and I just never got it. I took lessons and stuff like that, but it was different, because when I was doing trumpet, I was reading sheet music and I was learning by looking, there’s a thing called Tablature, where it’s like you see a drawing of the fretboard with numbers, and that’s where you’re supposed to put your… It’s kind of paint by numbers. And so, I learned it in a completely different way, but I was still terrible at it and I didn’t get it. It’s actually taken me a long time to understand exactly what the issue was, but it wasn’t until I really got into punk and I saw bands. I saw Sonic Youth, I remember especially, and it just blew my mind, because they violated the rules of what I thought music was supposed to be. I was like, this doesn’t sound right. These are not power chords, and this isn’t just have a shouty verse, and then a chorus part. It’s not going back. This is just weird. And then it occurred to me, you don’t have to write music the way people tell you it’s supposed to sound. That just opened up everything for me, and I was playing in a band. I was struggling with writing music, because I would try to write whatever was popular at the time, or whatever sounded other bands that I was listening to. And somehow I kind of morphed into just grabbing a guitar and just doing stuff. And I realized a part of my problem with doing music before was, I didn’t enjoy trying to play stuff that other people played. I just enjoyed music just dripping out of me and spilling out, and just doing stuff. And so, then I started to say, what if I don’t play a chord? What if I just play notes that shouldn’t go together and just mess around with stuff? Then I said, well, what if I don’t do four beats? Go na, na, na na, one, two, three four, one two, three four, one, two, three, four.
What if I go one, two, three, four, five, one, two, three, four, five? And started messing around with time signatures. Then I was playing in this band with a great musician, Brent Ritzel, who was in this band with me, and he taught me about arranging songs. And it was like, what if we take this part and instead of make it go back and forth, we make it a circle, or what if we make it a straight line, or zigzag, just make it nonlinear in these interesting ways? And then next thing you know, it’s the whole world sort of opens up as, and then what I started to realize, especially so you could appreciate this as a musician, I think. So time signatures. So we are so brainwashed to think in four-four, right? Every rock song you could think of almost is in four-four. I know you’re a Floyd fan, So think of Money by Pink Floyd, right?
Lex Fridman
Yeah.
Yeah.
Charan Ranganath
You feel like it’s in four-four, because it resolves itself, but it resolves on the last note of… Basically it resolves on the first note of the next measure. So it’s got seven beats instead of eight where the riff is actually happening.

Lex Fridman
Interesting.
Interesting.
Charan Ranganath
But you’re thinking in four, because that’s how we are used to thinking. So the music flows a little bit faster than it’s supposed to, and you’re getting a little bit of prediction error every time this is happening. And once I got used to that, I was like, I hate writing at four-four, because I was like, everything just feels better if I do it in seven-four, if I alternate between four and three, and doing all this stuff. And then it’s like jazz music is like that. They just do so much interesting stuff with this.

So playing with those time signatures allows you to really break it all open and just, I guess there’s something about that where it allows you to actually have fun.

Charan Ranganath
Yeah, I guess it would be. So instead of might go, instead of playing four beats in every measure, na-na-na-na-na-na-na-na. You go, na-na-na na-na-na na-na-na-na-na, and just do these things. And then you might arrange it in weird ways so that there might be three measures of verse, and then five measures of chorus, and then two measures. So you could just mess around with everything.

So I mean, it depends. So a lot of my style of songwriting is very much in terms of repetitive themes, but messing around with structure, because I’m not a great guitarist technically, and so I don’t play complicated stuff. And there’s things that you can hear stuff, where it’s just so complicated. But often what I find is having a melody, and then adding some dissonance to it, just enough, and then adding some complexity that gets you going just enough. But I have a high tolerance for that kind of dissonance and prediction. I think I have a theory, a pet theory, that it’s like basically you can explain most of human behavior as some people are lumpers and some people are splitters. And so, it’s like some people are very kind of excited when they get this dissonance and they want to go with it. Some people are just like, “No, I want to lump everything.” I don’t know, maybe that’s even a different thing, but it’s basically, it’s like I think some people get scared of that discomfort, and I really-

Which is perfect, because we’re Pavlov’s Dogs and Pavlov, of course, was basically created learning theory. So there’s that, but also it’s like, I mean, Iggy in the Stooges, that song, so I play and sing on it, but it’s just like it devolves into total noise, and I just fall on the floor and generate feedback. I think in the last version, it might’ve been that, or a Velvet Underground cover in our last show, I actually, I have a guitar made of aluminum that I got made, and I thought this thing’s indestructible. So I was just moving it around, had it upside down and all this stuff to generate feedback. And I think I broke one of the tuning pegs.

I think in the last version, it might’ve been that, or a Velvet Underground cover in our last show, I actually, I have a guitar made of aluminum that I got made, and I thought this thing’s indestructible. So I was just moving it around, had it upside down and all this stuff to generate feedback. And I think I broke one of the tuning pegs.
Lex Fridman
Oh wow.
Oh wow.
Charan Ranganath
So I managed, I’ve managed to break an all metal guitar. Go figure.

Human mind
Lex Fridman
A bit of a big ridiculous question, but let me ask you. We’ve been talking about neuroscience in general. You’ve been studying the human mind for a long time. What do you love most about the human mind? Like, when you look at it, we look at the fMRI, just the scans and the behavioral stuff, the electrodes, the psychology aspect, reading the literature on the biology side, in your biology, all of it. When you look at it, what is most beautiful to you?

Charan Ranganath
I think the most beautiful, but incredibly hard to put your finger on, is this idea of the internal model, that it’s like there’s everything you see, and there’s everything you hear, and touch, and taste, every breath you take, whatever, but it’s all connected by this dark energy that’s holding that whole universe of your mind together. And without that, it’s just a bunch of stuff. And somehow we put that together and it forms so much of our experience, and being able to figure out where that comes from and how things are connected to me is just amazing. But just this idea of the world in front of us, we’re only sampling this little bit and trying to take so much meaning from it, and we do a really good job. Not perfect, I mean, but that ability to me is just amazing.

Yeah, it’s an incredible mystery, all of it. It’s funny you said dark energy, because the same in astrophysics. You look out there, you look at dark matter and dark energy, which is this loose term assigned to a thing we don’t understand, which helps make the equations work in terms of gravity and the expansion of the universe. In the same way, it seems like there’s that kind of thing in the human mind that we’re striving to understand.

Charan Ranganath
Yeah. Yeah. It’s funny that you mentioned that. So one of the reasons I wrote the book Amongst Many is that I really felt like people needed to hear from scientists. And COVID was just a great example of this, because people weren’t hearing from scientists. One of the things I think that people didn’t get was the uncertainty of science and how much we don’t know. And I think every scientist lives in this world of uncertainty, and when I was writing the book, I just became aware of all of these things we don’t know. And so, I think of physics a lot. I think of this idea of overwhelming majority of the stuff that’s in our universe cannot be directly measured. I used to think, I hate physics. Physicists get the Nobel Prize for doing whatever stupid thing. It’s like there’s 10 physicists out there. I’m just kidding.

Lex Fridman
Just strong words.
Just strong words.
Charan Ranganath
Yeah, no, no, no, I’m just kidding. The physicists who do neuroscience could be rather opinionated. So sometimes I like to dish on that.

It’s all love.
It’s all love.
Charan Ranganath
It’s all love. That’s right. This is ADHD talking. So, but at some point, I had this aha moment where I was like, to be aware of that much that we don’t know, and have a bead on it and be able to go towards it, that’s one of the biggest scientific successes that I could think of. You are aware that you don’t know about this gigantic section, overwhelming majority of the universe. And I think the more what keeps me going to some extent is realizing changing the scope of the problem, and figuring out, oh my God, there’s all these things we don’t know. And I thought I knew this, because science is all about assumptions, right? So have you ever read The Structure of Scientific Revolutions by Thomas Kuhn?

Yes.
Yes.
Charan Ranganath
That’s my only philosophy really, that I’ve read. But it’s so brilliant in the way that they frame this idea of, he frames this idea of assumptions being core to the scientific process, and the paradigm shift comes from changing those assumptions, and this idea of finding out this whole zone of what you don’t know to me is the exciting part.

Well, you are a great scientist and you wrote an incredible book, so thank you for doing that. And thank you for talking today. You’ve decreased the amount of uncertainty I have just a tiny little bit today and reveal the beauty of memory, this fascinating conversation. Thank you for talking today.

Thanks for listening to this conversation with Charan Raganath. To support this podcast, please check out our sponsors in the description. And now let me leave you with some words from Haruki Murakami. Most things are forgotten over time, even the war itself, the life and death struggle people went through is now like something from the distant past. We’re so caught up in our everyday lives that events of the past are no longer in orbit around our minds. There are just too many things we have to think about every day, too many new things we have to learn. But still, no matter how much time passes, no matter what takes place in the interim, there are some things who can never assign to oblivion, memories who can never rub away. They remain with us forever, like a touchstone.
