We’re talking about a society that was right in the middle of one of the main corridors of empire building and new religions in the world. This is the most dangerous neighborhood that you can possibly live in.

Yes. It’s tremendous instability.
Lex Fridman
Almost all were—of these emperors—were generals, and almost all were murdered by their men. So civil war was the norm, hyperinflation, economic crash, plus there’s a plague. There’s just a lot of chaos.

Anthony Kaldellis
Here’s why I don’t think the Eastern Roman Empire is a military dictatorship. Even though, again, the emperors control the armies and the armies themselves will often have a say in who becomes emperor, like through the civil wars that we mentioned. The reason why I don’t think it’s a military dictatorship is because they almost never, very, very, very rarely use the army as an instrument of social control. Sometimes these eunuchs were extremely competent like Narses, Justinian’s general, who defeated the Goths in Italy in this massive battle. Like, this guy was a total hardass. And he’s this little old man. He was very old, and he was tiny, and he was a eunuch, and the Goths laughed at him, but he had the last laugh.

The Roman Empire and the Byzantine Empire
Lex Fridman
You’ve described that the Byzantine Empire is the Roman Empire, that calling it the Byzantine Empire is an invention of historians writing long after the empire has collapsed, that the people of that time considered themselves Romans, and that the so-called Byzantine Empire never actually existed, that it was, in every legal and cultural sense, the Roman Empire continuing unbroken.

Lex Fridman
So let’s get our terms right in the grand historical context. What is the Byzantine Empire, and why should we just call it the Roman Empire?
So let’s get our terms right in the grand historical context. What is the Byzantine Empire, and why should we just call it the Roman Empire?
Anthony Kaldellis
So Lex, the burden of proof is on those who would assert that what we’ve been calling the Byzantine Empire is something other- … than the Roman Empire, because all of our sources are very clear about this. And we’ve known about this. We’ve always known about it. It’s almost a form of cognitive dissonance, right? It’s like when you know something is the case, but you carry on as if it’s not.

Anthony Kaldellis
So the Eastern Roman Empire, this is the direct continuation of the ancient Roman Empire in the East, right? Everybody knows the Western Empire fell in the fifth century. And for many conceptions of Western history, that was sufficient. Like, that’s when we just called it. The Roman Empire fell in the fifth century. And we kind of, yeah, we kind of know that the eastern half survived, but we don’t want to include that in our cultural genealogy. And so we kind of pretend that it became something else. But in fact, it called itself the Roman Empire. Its subjects were Roman citizens. They called themselves Romans all the way down through to the end and beyond.

Anthony Kaldellis
So there are a number of reasons why Western Europeans wanted to think that the Eastern Empire is something different, and those reasons have created these models where they called it the Empire of the Greeks for 1,000 years, then they switched to Byzantine Empire for very political reasons. Now that’s collapsing. So we’re now moving into a phase where we have the long Roman Empire. We recognize that the history of the Roman state, the Roman polity, is something that lasts an extraordinarily long time. Very unique, almost, in history, from antiquity, like the archaic period, down to the 15th century.

Lex Fridman
I think it would be really nice to actually look just for a brief moment at the grand scale of the full Roman state as it lasted for over 2,200 years. So its founding, 753 BC, to let’s say the fall of Constantinople in 1453 AD. So can we try to give a big picture overview of everything that happened?

Anthony Kaldellis
Okay, so first we have a period of the kings. This is almost legendary, from like the eighth century BC down to around 510 BC. So this is when Rome is ruled by a series of local kings. The kings are expelled, and the republic, or what we call the republic is instituted, and this is a regime that’s governed by mostly an aristocracy, but with cooperation from the people of Rome. In various ways, the arrangements change over the centuries. So that lasts for about five centuries. And then we have the end of the republic in the era of Julius Caesar and Augustus Caesar, when the civil wars lead to the creation of an imperial monarchy-

Anthony Kaldellis
… right, under Augustus. So that’s, we date that roughly either, yeah, 27 BC, something like that. And thereafter, it is an imperial monarchy for the next millennium and a half. Very broadly, we can divide that into two phases, one where the center of power is in Rome, and one where it’s in Constantinople. And, you know, we can debate the dates of when that transition takes place. These big transitions usually take place over long periods of time. They’re not, like, very sudden. So that’s the big picture. Kings, republic, imperial monarchy.

2,200 Years of Roman History
Anthony Kaldellis
Yes.
Yes.
Lex Fridman
And then maybe what are the different terms that we could be using for the Byzantine Empire, including Byzantium? Is it also fair to say the Late Roman Empire?
And then maybe what are the different terms that we could be using for the Byzantine Empire, including Byzantium? Is it also fair to say the Late Roman Empire?
Anthony Kaldellis
So Late Roman Empire we use for both east and west, starting around the reign of Diocletian maybe, even a bit earlier, so during the third century AD. And that goes down to maybe the early seventh century. So that period we call Late Roman Empire. And if you ask me to define its principal characteristics, it would probably be the tax system and the administration, the bureaucracy— … of the later Roman Empire is that that comes from mostly Diocletian and Constantine’s reforms.

Okay.
Okay.
Lex Fridman
So in 753 BC, Rome, a small city state, is founded, and in 509 BC, the kings are overthrown, and the Roman Republic is born. 390 BC, the Gauls sack Rome, and this, I believe, among other events throughout its history, is a formative trauma that hardens Rome’s security obsession. It turns out, throughout its history, people want to attack from different directions, and so you have to defend. So there’s two wars, as we’re actually saying off mic. There’s two kinds of military operations. One is wars of conquest and expansion, and one is more defensive. And we’ll talk about how the military changes throughout its history to allocate more effort to one versus the other.

Lex Fridman
In 264 to 146 BC, the Punic Wars and the survival against Hannibal transform Rome into a Mediterranean superpower. Then, like you mentioned, Caesar in 49 to 31 BC, Caesar’s crossing of the Rubicon to assassination of Caesar to the Battle of Actium, and then the Civil War dismantles the Republic and concentrates power in a single ruler, Octavian, AKA Augustus, the first Roman emperor, let’s say. Then 27 BC, Augustus founds the Principate, really low-key monarchy. And so officially, that ends the Republic, and then that begins 27 BC to 180 AD, the Pax Romana, which is a period of relative peace and stability. And a lot of the emperors we know of, the sexy, popular emperors all come from that period.

Marcus Aurelius, who I’m a big fan of, from that period. Then that takes us to 284 AD, the guy we mentioned, Diocletian, who rebuilds the state. Emperors drop the first citizen mask, this perception of the way, and we’ll talk about this, the, the persona that’s presented by the state. 312 AD, Constantine defeats Maxentius at the Milvian Bridge to become the sole ruler of the western half of the empire, and then founds Constantinople in 330 AD. East and West are split in 395 AD. Visigoths sack Rome in 410 AD. The West falls in 476 AD as the last Western emperor is deposed. And then we sort of focus more on the East Roman Empire with 527. In the 6th century, Justinian’s reign. In the 7th century, Heraclius defeats Persia and then loses against the Arabs.

There’s the Arab conquest continuing in the 7th century. In the 8th, the Arab siege of Constantinople fails. There’s the Macedonian dynasty that you have an excellent book about. And then the Crusades, and then eventually leading to Constantinople falling in 1453 AD. As a person who understands the full journey of it with a focus on East Roman history, is there obvious glaring holes or incorrect things in what I just said?

Anthony Kaldellis
No, nothing incorrect. I would say if you wanted to produce a sort of very swift timeline of its history, it’s obviously important to focus on the moments when lots of territory was lost to foreign invaders, and these are actually three main moments. There’s the Arab conquests in the 630s. This is a decade. In a decade, that war was lost. It is the Seljuk Turk conquest of Asia Minor, modern Turkey, in the 1070s, and that was very swift and partly reversed afterwards, but only partly. And then there’s the Fourth Crusade, 1204, when the armies from mostly France sack, conquer Constantinople, and dismember the empire as much as they could. It didn’t last that long. The Romans managed to regroup and recover, but those are the three main crisis points.

Anthony Kaldellis
They are very swift, but they cause incredible damage. For all the rest of its history, it is a state and society that is generally sort of consolidating, you know, regrouping, and generally engaged in slow but steady economic growth, territorial expansion on a small scale, but steady. So we can talk about this. It’s… I think it’s an important thing to keep in mind about the big picture, that the defeats were swift and kind of, you know, terrible but most of its history is one of slow growth.

There’s some traumatic events that have a big impact, but a lot of the developments we’ll talk about it might seem or feel like there’s a particular moment when those developments or changes in the way the government or the military is structured arise, but really it’s a gradual process.

Exactly.
Exactly.
Lex Fridman
And so that’s the tension we have to be constantly dancing with.
And so that’s the tension we have to be constantly dancing with.
Anthony Kaldellis
Yeah, so as historians, this is a point of method, and it’s very important. There are moments when, like, individuals with a great deal of power make choices that impact everybody else and have, you know, long-term consequences downstream. Constantine’s conversion to Christianity, for example, right? Not something that anybody could have or did predict. Okay. Otherwise, most of the developments that we identify by specific dates, like you mentioned 395, the division of the eastern and the western empires, those are conventional dates that we use to actually capture what is in fact a much longer process. There was no split between the two halves. It was one among many allocations of jurisdiction to, like, one son and another son in the east and the west.

Anthony Kaldellis
The two halves were subsequently reunited, then they kind of divided again among different emperors. It’s just a process, and so we sometimes use fixed dates for what is in fact a process. Or for 476, the fall of the Western Empire, that’s just the last date. It’s actually a very long process that took decades. Right? So that’s just something to keep in mind, that sometimes we’re talking about processes, sometimes we’re talking about very discrete events with long-term consequences. Yeah.

Lex Fridman
Maybe an impossible question for a Roman state that lasted over 2,200 years, but is there a kind of through line, a thread, a soul that runs through the entire history of the Roman Empire? As you said, it’s a slow transformation and evolution. But if we dare call the whole thing Roman, Rome, the Roman state—

… is there some aspect, some characteristics that run through the whole thing?
Anthony Kaldellis
I think so, yes. By the way, you know the metaphor of the Ship of Theseus? Okay. So in case the audience doesn’t know it, this is when there’s a ship, and it’s, you know, at sea, and over time, like, every component of that ship is replaced with some other component, so that by the end of the story, it has none of the original parts. But it’s, like, in a certain sense still that ship because of the story, right? The… Okay. So Roman history is different from, let’s say, Greek history or Christian history, right? Christian history is the story of a religion. It can be in any country, among any ethnic group. It’s here, there, right? It’s everywhere. But you still have histories of Christianity. It’s the same with, say, Greek culture—

Anthony Kaldellis
… or your Greek literature, right? It’s not a function of a particular state. Ancient Greeks were famously never united in a state. But it’s people who culturally accept that tradition as their kind of elite prestige culture and engage with Homer and Philo- and Plato and so forth. And they can be anywhere. Roman history is not like that. Roman history is very specifically the history of a state or a political community. And so this is the community of the Roman people, the Roman citizens. And it is in gradual evolution, but at no point is there a rupture in that history such that its members would ever think that something dramatic had changed, and that they’re no longer part of that story.

Anthony Kaldellis
So in the same way as the, as the ship I just mentioned, in other words, it’s the narrative that you tell about it where the changes that take place to it make sense only when you see them within the context of that story. It’s the same with Roman history. Yes, there are changes. Like, eventually everything changes. But it happens so gradually that it doesn’t seem that way to anyone living in it. And so the narrative of the history of the Roman people is what holds all of this together.

How important is it that, so you mentioned Greek culture. So a lot of my friends who are Greek are extremely proud of being Greek. There’s certain cultures that are proud.

Anthony Kaldellis
Sure.
Sure.
Lex Fridman
And it’s not a momentary ephemeral thing. It feels like a thing that has lasted for many generations. And so that is an engine that propagates through time that carries that culture forward. And so does a similar thing apply for the Roman Empire in a different way? Maybe ’cause you say it’s a political kind of community, that means a set of ideals. And we’ll talk about, because those ideals become even more concretized and explicit, I think, through the East Roman Empire, because one of the things you talk about is that the citizens of the empire are kind of all connected, that they are-

… engaged in this whole sort of machinery. Anyway, that’s a complicated way of asking, is, is there some elements that Greek pride, dare I speak, is there some kind of Roman pride that propagates the thing?
Anthony Kaldellis
Oh, there totally is. You can find authors and historical agents who definitely display this or talk about it. But we don’t wanna make that the center of the story or the basis for any analysis because… So what you’re observing in your Greek friends is also the result of modern nation building, is it’s the result of modern systems education, and sort of national identities, and these are fostered and created through all kinds of media and institutions. It’s, it’s just a different situation altogether. What you find in ancient republics or medieval states is more something like a consensus to be ruled, to be, to rule and to be ruled in this particular political community. Now, some members of it may definitely, and in fact did have this kind of pride.
Oh, there totally is. You can find authors and historical agents who definitely display this or talk about it. But we don’t wanna make that the center of the story or the basis for any analysis because… So what you’re observing in your Greek friends is also the result of modern nation building, is it’s the result of modern systems education, and sort of national identities, and these are fostered and created through all kinds of media and institutions. It’s, it’s just a different situation altogether. What you find in ancient republics or medieval states is more something like a consensus to be ruled, to be, to rule and to be ruled in this particular political community. Now, some members of it may definitely, and in fact did have this kind of pride.
Anthony Kaldellis
I’ll give you an example. So there’s an ambassador in the sixth century, and he’s concluding a deal with the Persians. And you know, the Persians are skeptical ’cause, you know, Romans can’t always be trusted. But this guy says to them, he says, “And let me just tell you, you’re making a deal here with the Romans. The Romans. The name should say it all.” Like, you, okay, and you get a sense that this is, he’s expressing a certain pride in, like, being a bearer of the Roman tradition and speaking for the emperors and the Roman Empire. I mean, that’s, for him, this was something very, very momentous. You find these kinds of examples, so these people exist. But I wouldn’t wanna make that the basis for like an analysis of how the society works as a whole.

For the most part, it was something like a consensus where, you know, subjects or citizens, however you wanna call them, they agree to, um- Let’s say be taxed and be ruled by political authorities because of what they get in return, and there’s this kind of understanding of a mutual set of responsibilities. And my concern, among other things, is to try to explain how this society held together for so long. Pride, yes, among some people, definitely. You find it in the sources. But sources are, texts are written by literate, usually elites. So this is a small part of the population. We can’t automatically extend their attitudes to everybody else.

So in dealing with everyone else, we have to work with different kinds of materials, different kinds of assumptions. We can’t just posit that they’re just proud of being Roman. They could have been. We don’t know that, though. We can see other sorts of things about them. Like, for example, did they pay their taxes? Did they try to rebel and leave the empire? So those are the kinds of things that, that, that I look for.

Pride is one component, but there could be other explanations and factors that explain what motivates a soldier to defend the capital, for example. Like, what motivates a particular person to pay the taxes. And then this is, this is something that we’ll definitely talk about. But just to linger at the big picture, if the Romans from the different periods met, how different would they be from each other? Like, if I, if I brought to you… This is one of those, you know, there’s like- … blind taste tests you can do with food.

I mean, I get asked this in a, in a, in a much more radical form, which is like if you take someone from, like, around 1453 who’s a Roman and a subject of this Roman, and compare, and, and, you know, compare him or have him meet, you know, in your imagination with someone from the ancient republic.

… could they find any kind of agreement on, on what it means to be Roman and recognize each other as belonging to that polity? This, this is a very difficult thing to… Like, now, I can point to a number of things that they would find eventually. And, you know, if you told them, “Yo, you’re both Romans, you’re both from this long history, now you have to find, you know, what you have in common,” I think they could find things. But before we talk about those, if, if you wanna get into it, let’s just say that the question can even be posed about Romans who live at the same time.

I mean, if you take a senator from the age of Cicero and someone from the slums of Rome, who’s maybe the son of a slave who was brought from the East by some general a generation ago, and put them in a room and say, “Now, you discuss. You, you’re both Romans. What do you have in common?” They might have trouble in coming up with something.

Right? So let’s not minimize the sheer diversity of experiences and sort of life experiences of Romans who are living at the same time. The important thing is that a change is always happening, and from my standpoint this change is sort of cumulative, so it results in Greek-speaking Orthodox Christian Romans in Constantinople who at first sight might have little to do with Latin-speaking, you know, non-Christians or worshiping the ancient gods, Romans from a republic in Rome. And those are very, very different situations, and no doubt they would, they would look and seem foreign to each other, right?

The question is, why do we assume that someone like Hadrian, right, an emperor from the second century sort of a very cosmopolitan figure who travels around the empire with his Greek lover and, you know, writes poems and is, has a Greek beard and, you know, loves Greek culture and has much to do with someone from the Middle Republic who’s, you know, some warrior who’s chasing down cattle from the Samnites. I mean, and yet the way we understand history is that, oh no, those belong together. Hadrian and this ancient Roman from the fourth century BC.

One of the ways we can try to analyze this is, for example, looking at a very specific role in society across time. So we can look at soldiers, how they solve violence, for example. That’s one way. So you’re making me realize that we can just take 1,000 different professions and positions in society and really specifically look at what the experience of the world was like. And so one of them is the view on violence across time. And, and then the other is the view on the role of the government- … across time.

That’s an excellent way of putting it. So take soldiers, for example. They swear an oath. Right? Now, we don’t have the oath for every given period. We have some approximations of it, some hints of what it contained, but we know that Roman soldiers swore an oath, like, throughout all of the centuries of the empire. Sometimes they might add, like, a Christian formula to it. Sometime before that, not. But they swore basically to protect the republic or depending on what term they used or the empire or the emperor. And this is something that they would have recognized very quickly. Like, if, if they met each other over time and said, “Hey, what was your oath like?” And they recited it, this would have made much sense to them, right?

Or take, for example, a woman who runs a business, right? From any century of the empire. It, it would have been, especially the later you go, the, the more so, that this woman is enabled to do this by virtue of Roman law. Of certain, you know, Roman law of property and inheritance and, and marriage, but also regulations regarding who can do what and what kinds of properties women can handle and under what circumstances. This is something that Roman women had in common that many other cultures did not. So I’ll give you an example. So for example, in the 10th, 11th century, there are Jewish women who live in the Eastern Roman Empire-

… who realize that they have more rights in Roman courts than in rabbinical ones, and they take their disputes to the Roman courts. Now, the thing is that for the Romans, these are property matters- … not religious matters. But for the rabbis, these are religious matters. But the Roman courts trump the Jewish courts- … in the empire, right? And so you end up with a situation where Jewish women have more rights- … than Jewish women do elsewhere, because there Roman law is not operative. And there you go. Right? Like, these things matter, right? And that’s a function of imperial law.

And this, this would be an interesting actually interplay between the law and religious institutions- … Throughout the East- … Roman Empire. So you argue that even though the personality of the various emperors varied, as we’ll talk about, and as they’re often venerated, celebrated, criticized, talked about, the late Roman Empire was projecting a persona to its citizens that was consistent throughout its history. Can you describe what you mean by this and describe the different detailed characteristics of this persona?

Anthony Kaldellis
Yes. So this persona, it’s what the governments or the emperor, the court, and the spokesman, the bureaucracy want their subjects to think this whole thing is about. Like, how is power being used, why, and for whom, right? And they do so in laws that they promulgate throughout the empire. Sometimes they have these laws read in church, for example, or posted publicly. They’re definitely eager to have them communicated to as many people as possible. But they’re also a function of imperial rhetoric so the way you praise an emperor, the way you talk about an emperor. You find this language in petitions, so this is a hugely important glue for this society, is that anyone could basically petition the authorities for let’s just say just about anything.

That’s not technically true, but there’s a lot of petitioning going on. So, you know, if you think something’s wrong or you’ve been treated unjustly, you can petition local officials, even imperial officials. You can petition the emperor, you can… Right? And the expectation is that that petition will be read, addressed, and answered. It might not be answered in the way that you want, but it will be answered. And those responses contain this language also, right? So these are the different media through which the emperors are broadcasting this persona, and that persona is what? Basically, that the authorities are responsive to the needs of their subjects, that they are often accountable.

In other words, they understand that they are exercising public power, and that their mandate is to exercise it solely for the benefit of their subjects. They keep saying this. So renouncing any kind of private interest. In other words, “We’re not doing this for our benefit,” say the authorities. “We’re doing this for your benefit.” Also that they’re proactive. So the emperors are constantly saying that, “We’re planning ahead. We, we’re trying to foresee what problems you might have, and we are solving them before you experience them.”

And that they are also working very hard. So hardworking. In fact, one of the cliches that they keep using is sleepless. The emperors keep saying that, “I’m losing sleep over this.

He was a workaholic. That is conceded by even his enemies. All night he was up just, just hauling officials in at any old hour to talk about whatever, you know, wars and architecture and laws and religion and theology and whatever. So the emperors are projecting this image, right? So that’s what I call the persona. Tireless effort to work on behalf of subjects, to do so responsibly, to be responsive and accountable. In other words, if some of my officials breaks the law or oppresses you, I’m giving you instruments, like legal instruments, by which to hold them to account.

And you draw this distinction between rhetoric and action, what the authorities say and what they actually do. So when you say persona in the modern times, some of that could be reframed as propaganda- … for example. And propaganda implies that the rhetoric, that there’s a big gap between the rhetoric and the action. And one of the things you said you took away from reading Machiavelli is that we should judge people not by what they say, but by what they do. So how much of the Roman Empire’s government of what they espoused was merely rhetoric, and how much was true in how they acted?

Yes. This is a key lesson I took from reading Machiavelli, and I found this a very insightful way of thinking about politics, and I would recommend that anybody kind of practice this way of looking at the world, right? People and states and, you know, powerful people can say anything they want to. At the end of the day what matters is what they actually do. And this doesn’t mean that what they say is irrelevant, even if it’s discordant with what they do. But nevertheless in the case of the East Roman state, my research suggests that the emperors and the authorities were generally sincere in what they said. In other words, I have found that they generally did what they said they were going to do overall. Not perfectly, obviously.

And of course, these are human beings we’re talking about. The, right, the human societies, there was a lot of, you know, corruption, and you name it. Abuse— … of course. Of course there is. But overall, I think that there was a sufficient level of understanding that the emperors are in fact doing this, and they were actually incentivized to do this. We can talk about how. Because they were also in a pretty vulnerable situation too, so they needed their subjects to be relatively content on this front.

A number of things, but ultimately it is that there is no right to the throne. And this is a function of the Roman matrix of politics here. In other words, so here’s a bit of a paradox. What we call the Roman Republic was the most imperialistic phase of Roman history. Like this is when the Romans did most of their conquering. What we call the empire is much less imperialistic in this way. That’s much more defensive in its approach, right? And yet our terms are a little mismatched in that way. The empire is more a function of that it has an emperor rather than it is engaged in imperialism. And that emperor emerged out of the republic.

But emerged out of the republic in a very strange way. In other words, not as a dynasty that created the state. So for example, if you think of the Ottoman Empire, many other empires, they… The whole thing existed because this dynasty engaged in conquest and- … was successful in creating the state, and so the dynasty was like at the heart of the state. But that’s not at all the case in the Roman Empire. The emperor is a figure who emerged within a republic, and in order to create peace after the civil wars, those emperors had to, for a long time, kind of pretend that they were not what they really were.

By basically, you know, continuing to flatter the idea of a republic that is, you know, that has a first citizen maybe. “Oh, no, no, I’m not a king. I’m just, I have this office and that office and that office.” “Whatever the Senate has given me.” Now, we understand that’s a facade, but the fact that they had to create this facade at all is very important.

Can we actually just linger on that? I mean, how much of this… ‘Cause you said they had to create this facade.

Exactly. Because, you know, just because you ended one civil war doesn’t mean that there’s not going to be another. You have to create a consensus such that people don’t want to have another civil war. If he did what you said, which he in theory could have done, but that would’ve just led to more wars, right? So the problem is that the emperors, even those who come to power through violence, they can’t prevent other people from trying to come to power through violence because like I said, no one has a right to the throne.

So the problem is that the emperors, even those who come to power through violence, they can’t prevent other people from trying to come to power through violence because like I said, no one has a right to the throne.
Lex Fridman
We should also say one more thing where, dare I carefully say this, but it seems like riots and civil wars is a feature, not a bug of the system. This is a different thing that we have to the modern day, is because the threat of a civil war, a violent civil war where you overthrow the government and there’s just a lot of- … death and struggle for power is always a threat. That’s another incentive that, I guess the stick, not the carrot, but the stick for the emperor to behave.

Anthony Kaldellis
Yes. It’s the main one. In other words, just take the thousand years that I study. There’s something like 120 civil wars. Now, these are usually very swift. They’re over quickly, and they’re never about ideology. So they’re not like modern civil wars. Right? It’s not about slavery or the rights of kings or whatever. No, no, no. They’re solely about who has the power. All sides have the same ideology. They talk about, you know, the responsibility of government in the same way, right? They’re just competing over who’s the best man to do the job. Right? And so once you have that situation… And it might not be a civil war, it could be a palace coup, it could be a kind of fighting in the capital-

… something like that. Once everyone’s taken their side and you have a winner, that’s the emperor and you often overthrow the previous regime. I’ll give you some statistics. Something like 46% of the emperors of Constantinople are overthrown through violence. 46%. And that’s almost half.

Anthony Kaldellis
Right? So that’s a huge, that’s a huge number, which means that every emperor is vulnerable and insecure, and they know it, right? So what they have to do is make sure that that doesn’t happen to them, and the way to do that is not by arresting and executing everybody you think might be a threat or just generally behaving like a, you know, a Caligula or a Nero. That will just get you killed. Like, they know this. So the best way to avoid that fate is to actually do the things that will make people happy so that they don’t support a rebel if a rebel decides to appear. And sometimes rebels would appear. There’s a kind of convention in Constantinople, like if you…

Sometimes you think, “Hmm, that emperor’s pretty unpopular and I think I can overthrow him.” What you would do is you would march down the center boulevard- … And, you know, you’d have your people just call the populace of Constantinople out to rally, to you know, maybe go to Hagia Sophia, the church, and just create a big crowd and call for the deposition of the emperor and, you know, maybe that would- And sometimes it did, and sometimes it didn’t, and the rebel or wannabe rebel would sort of proceed down the, the Mese, the boulevard, and people would just gradually just disappear, and then he’d be left alone- … and go up to Hagia Sophia as, as seeking asylum. Right? So that’s a bid.

Anthony Kaldellis
That’s someone making a bid for the throne, and it just goes disastrously bad. Other times, the people come out ’cause they hate the emperor, and they drag the emperor out and cut his nose off or whatever. So emperors are constantly trying to prevent that from happening, and the best way to do that is through goodwill.

Okay. You’re right. So here’s what elections do. Elections give a government a mandate for, I don’t know, four or five years, and during that period, you may be unpopular, but you’re legitimate, right, because of the institutions. Whereas in Constantinople, we don’t have those kinds of institutions. We have instead an ongoing referendum. We just call it a perpetual referendum, right?

And in fact, the emperors are, are, they’re conducting opinion polls in a sense because they appear in public. When they appear in public, everyone is expected to cheer and chant acclamations, right, like slogans. Right? So you have 100,000 people in the Hippodrome all chanting, you know, “Worthy” or “Many years for you, Augustus” or something like this. And if that happens, it’s great. But if you appear in the Hippodrome and people are, like, sullen or if the chanting is a bit tepid or if they’re booing, then you know something’s wrong, right? So you gotta find out what’s wrong. It could be something like the grain supply is, is, you know, not working or whatever. And so emperors are desperate to fix those problems.

… ancient Athenian democracy, which is a whole other thing. But you’re right. So it’s not just in the Hippodrome. It’s wherever people assemble in large numbers. So this could be military mustering grounds, right? So the army. The army is also the Roman people in a way, and in some cases, the most decisive part of it, right? So if an army gathers together and they decide they want a different emperor, that’s serious, and that can happen out in the provinces too. That doesn’t necessarily have to happen in Constantinople. There’s also Hagia Sophia, so the people gather in the church, or they gather in public spaces like the Forum of Constantine.

So this can happen anywhere where a large number of people can gather, and it’s, I don’t know if you wanna call it a democracy as such, but it is definitely a form of popular, let’s say, consultation and a testing of consensus. I’ll give you another example. So in the 1190s, the emperor—and it’s Alexius III—he’s being threatened by the German emperor. German emperor’s basically, “You, you, you pay me a bunch of money or I’ll invade.” Just straight up extortion. And Alexius decides, “Okay, I’m gonna, I’m gonna gather this money. I’m gonna impose these taxes.” And he gathers the people in the Hippodrome, and he says, “You know, we’re gonna have the German tax.”

He called it the German tax. And there’s such an uproar in the Hippodrome against this that he was like, “Uh, that wasn’t my idea. I don’t know where that came from. No, never mind. We’re not gonna have the German tax.” Fortunately, the German emperor died and, and nothing ever happened, but it gives you a sense of how emperors, like, literally can backtrack when they see that the people are against something in a matter of policy, right— … like tax policy. So yeah, there was this give and take. So institutionally, the emperor might look absolute, as you called him earlier. In practice, no. No. The ones that did that didn’t end well.

And we should say, going to Perplexity here, the Hippodrome of Constantinople was the main stadium and social center of the Byzantine capital, used primarily for chariot racing and imperial ceremony, and today survives in Istanbul’s Sultanahmet district. And the reason I looked this up, I wanted to see how many people. Shaped as a long U-shaped race course with a central barrier and tiered seating, it may have held from roughly thirty thousand up to a hundred thousand spectators, though exact capacity’s debated because archeological remains are limited. That’s a lot of people.

Thirty thousand is definitely a pretty un-underestimate. The Hippodrome is still there. I mean, you can see it from, it’s like satellite photos. The shape of it is still there.

And actually some parts of the build, the, the Sphendone, the, the sling around the southern side is still there. You can walk around it. And it’s right next to the palace. In other words, emperors didn’t have to go far. Now, sometimes there are events for replacing an emperor. So say the emperor dies in his sleep, and there’s no heir. This happens in 491, for example. And so the people gather in the Hippodrome in order to have a discussion with the court about whom to appoint. Now, in those kinds of contexts, it’s entirely possible that there are people also in the arena, like not just in the stands. I think some military units might have just been arrayed there rather than in the stands.

We should say, so like, I think the thing that was emphasized in the first paragraph is the, the athletic events and the entertainment events, right? Like the imperial ceremony. But there is a, a sort of a political gathering was also popular. The Hippodrome was not just for sport. It was where emperors appeared before the people, where acclamations, public punishments, and political demonstrations took place, and where the rival circus factions, blues, greens, reds, whites, became powerful social and sometimes paramilitary forces. And this goes on and on and on. So this was a place—

So it’s, it’s fascinating. We as humans, throughout our history, we try to figure out, okay, how do we figure out how to govern large collections of humans in a way that they’re represented, in the way that they don’t riot, they don’t rebel. In the way that we flourish together as a people, all this, all this kind of stuff. So this is a real… The East Roman Empire is a real study of something that seemed to have worked. There’s lessons there even for the modern times, I think. And modern times, again, is very early human civilization.

Edict of Caracalla
Lex Fridman
So if we can, before we go to Emperor Constantine the First and the founding of Constantinople, can we look at some maybe seminal events that led up to some of the topics we’ll be talking about? So one of them, maybe tell me if this is not as interesting as I think it is, but the Edict of Caracalla in 212 AD. So this is where you described that starting with Augustus in the early imperial period, government saw itself as a protector of the Roman citizens, which is a minority of the people living in the Roman Empire. It doesn’t consider the provincials. And then you described that the Edict of Caracalla extended full Roman citizenships to basically all free inhabitants of the Roman Empire. So what is it? Why was it done? Why is it important? And how did it change the Roman Empire?

Anthony Kaldellis
Right. I agree with you that this is, in fact, a very important… It’s a, it’s a real turning point in a sense, but it also is part of a process. So for various reasons, the Roman polity tended to bestow its metropolitan citizenship, that is, Roman citizenship on its allies, and eventually in time, on many people that it had conquered. And it had various mechanisms for doing so. It could bestow block grants. Sometimes it allowed its generals to bestow citizenship on people they thought would, you know, would be necessary players for controlling local societies. Sometimes they even allowed foreign cities to, like non-Roman cities, to decide who would get Roman citizenship by basically electing them to certain kinds of offices.

Anthony Kaldellis
Like they, they outsourced a lot of this. And so you have over time the steady growth of a Roman community of citizens who are not all in Rome, and who are not all of Roman origin, whatever that means, but they, they were not descended from people who were from Rome. And this proceeds, you know, it expands, it expands, it expands. By Caracalla’s time, so early third century AD, we can estimate that maybe at, at most a third of the free citizens of the empire are Roman citizens. Everyone else has local citizenship, like you’re Alexandrian or Athenian or, or whatever. And with… You’re subject to those laws. This emperor, Caracalla, now that’s his nickname. His reigning name is Marcus Aurelius Antoninus. So just like Marcus Aurelius, it’s the same name two generations later.

Yeah, so he issues this edict in 212 called the Constitutio Antoniniana, named after him. Some people at the time called it the Divine Decree, which basically extended citizenship to everybody. Now, we don’t know exactly why he did so. We can guess the reasons that he said he did so, and this was for religious reasons. In other words, he wanted people to go to the temples and pray and give thanks to the gods for him, for his survival out of a coup.

Which is whatever. And it’s possible that there was some kind of religious motivation here, and he wanted everybody to do so as Roman citizens to honor the Roman gods and something like that. Other historians at the time said he did it for tax reasons. We don’t know exactly. There might even have been a kind of ideology of a unified community across the empire playing in his, if not in his mind, in that of the jurists, that is the legal advisors that he had. So that’s possible. But less interesting than his motivations, more interesting are the consequences of this—

… and what it tells us about the Roman community. So imagine a situation where, like, no modern empire has ever done this really, right? When what’s significant about the Roman case is that not only did they extend citizenship to everybody, but they meant it. This is something that had teeth. In other words, it meant that the rights and opportunities that were available to Roman citizens, say, in the Roman Senate at Rome- … are now available to everybody. And within a generation, you have a situation where, like, all of the emperors are provincials, right? All the most powerful people in the empire are from the provinces.

Anthony Kaldellis
Yeah, and there’s a law of citizenship, and it, basically it says something like, “Anyone born within the Roman Empire is a Roman citizen.” And the Roman jurists and policymakers who were behind this had some very interesting ideas about, you know, creating this kind of community. Look, like, imagine if, I mean, it’s almost impossible to, to imagine, but the, the British at the time of the peak of the empire bestowed British citizenship on everyone, including in India, and, like, suddenly made positions of power in London available to people from India, like, including the throne. Like, it’s just unthinkable.

Anthony Kaldellis
And that has to do, you know, with race and colonialism and all kinds of things, right? But not in the Roman Empire. So we have a situation where the emperors are all from the provinces. The most powerful officials are all from the provinces. And so a century later, when Constantinople is created, this is, it’s created, right, like, in, in the Bosporus, so, like, where modern Istanbul is, in the Eastern Roman Empire. It’s created within the preexisting Roman context, right? It doesn’t bring Romanness to the East. It’s already there. And so it’s not such a leap to create a center of Roman power in the East because of that.

Lex Fridman
And you’ve helped put together a book on the history of intellectual thought in the East Roman Empire. But this is the interesting thing here, and I can ask that many times, but let me ask it here also, is the great man, the great woman view of history. Were there, like, Thomas Jefferson or those types of characters in the meetings as, as, as they’re executing on the edict or developing the edict?

Anthony Kaldellis
Yeah. For the edict, I suspect that yes, there were a few people who were behind it, and quite possibly jurists, that is, Roman legal scholars. And 212 is in an age of very important Roman legal scholars: Ulpian, for example, and others. But we just don’t have those… We have- … minutes of the meetings for the- … American Revolution. Not only do we not know who was in the room, we don’t actually even have the whole edict. We have a papyrus fragment, this is a piece of ancient paper- … that’s mostly torn and mutilated, and we have, like, a bit of a paragraph from it.

In Greek, not even the Latin original. And it’s kind of torn, but it actually preserves the key clause. Right? And that’s, that’s all we have of the original. We have contemporary sources that mention it, we have legal documents, but nothing like a, like we can talk about the people involved in it. Or even how it was immediately implemented. Like, suddenly we know everyone in the provinces, like, there’s this explosion in the number of people called Aurelius, because that was his, his Roman family name. And so when you acquired citizenship from that edict, you became an Aurelius. Right? And there are lots of Aurelii suddenly all over the place. Like, we can see it immediately. But we can’t actually see the implementation.

And then you said that one of the important aspects about this edict is that giving equal rights to provincials was one of the things that helped deal with the crisis of the third century, and was the thing that, I think you said, quote, “sapped discontent from the relevant populations,” which then minimized the probability of uprisings.

Well, now that’s a very long-term process. Now, the third century is chaos, there’s a crisis, it’s a mess, right? So what follows the edict is quite a few decades of unrest.

Okay, let’s put it mildly. Let’s talk about the crisis of the third century, where 26 emperors were murdered in a period of 50 years.

Anthony Kaldellis
Yes. It’s tremendous instability.
Yes. It’s tremendous instability.
Lex Fridman
So there’s civil wars nonstop. Almost all of these emperors were generals, and almost all were murdered by their men. So civil war was the norm, hyperinflation, economic crash, plus there’s a plague- … from 249 to 262 AD, which is a pandemic, possibly smallpox or Ebola. It killed up to 5,000 people a day in Rome alone, devastating the tax base and army recruitment pool. And the empire fractured into three pieces, but then Emperor Aurelian miraculously reconquered them in a period of five years. So just a lot of chaos. It, it deserves the name, the Crisis of the Third Century.

Anthony Kaldellis
Yeah, it’s a perfect storm. Yeah, I mean, you have a crisis of imperial legitimacy. Basically, the army’s proclaiming emperors left and right. In an odd sense, ironically, this is in part because there are now a lot more stakeholders in the Roman tradition, right? There’s all of these provincial armies, and they’re appointing their generals as rival emperors. But you also have a serious uptick in foreign invasions.

Anthony Kaldellis
In the north, you have the creation of the Sasanian Persian or Iranian Empire in the east, and this was very, very bellicose. So lots of foreign defeats. Armies are defeated by, you know, like, quote, “barbarian enemies.” You have eventually inflation, and you have plague. And so under the pressure, right, of all of those forces, it almost fell apart. Now, it didn’t actually. Inevitably, there are also historians who downplay the crisis. Of course, right, like, and legitimately so, right? We must push back against every of these characterizations.

Crisis of the Third Century
Lex Fridman
So it’s very important to actually remember about what the actual experience of the average citizen of the empire is like. Fair. Okay, so but how… Maybe there’s more we could say about the crisis. And then, of course, the crisis is in part resolved by Diocletian as he does a hard reset on the structure of the Roman system of government. So maybe you could speak a little bit more to the crisis that’s important for us to understand, and how Diocletian solves the crisis in 284 AD.

And we have what’s called sometime the Empire of the Gauls. Gaul are modern France and sort of Britain, for a while are, for a decade and a half or so, are kind of like this little separatist- … empire. So what’s interesting about that is that this was not an attempt to break away from the empire. In other words, it’s not some discontent provincials who are just tired of Roman rule and wanna break away and do their own thing. No. This is actually just a, it’s an attempt by provincial generals to take the throne, and does it to rule the entire empire. It doesn’t work. They get only as far as the provinces that they take. And the only way that they know to set up a state is to make it a Roman state.

Anthony Kaldellis
Right? Like, that’s the total of their political imaginary is like, “Well, we’re just gonna do a Roman thing here.” And maybe we’ll get, you know, we’ll reunite the empire ourselves, or as happened, Aurelian, that is someone from the other side, will reunite the empire. But it’s always a Roman model. Like, there’s, it’s almost like there’s no alternatives by this point. So that’s interesting. What Diocletian does essentially is the, the way I characterize it sometimes is that he turns the problem into its own solution. In other words, the problem is too many emperors or wanna-be emperors. Because there’s just more going on. Like, one emperor can’t deal with all these problems along the frontiers, with all the political problems.

So what he does is he deputizes some of his colleagues, people he was on very good terms with from the army. These are all Illyrians. They’re from… By the way, for a few centuries, the emperors are all from this region of the former Yugoslavia that’s the size of Scotland. Like, that’s where they all come from.

Lex Fridman
Well, what explains that?
Well, what explains that?
Anthony Kaldellis
The army. These are military men. Sometimes hard-drinking military men. Very good at their job like Aurelian, you mentioned, right? So there’s a series of Illyrian emperors who restore stability. And the reason why there’s so many Illyrian emperors is ’cause they worked their way up through the ranks of the army. And, you know, the regions of Yugoslavia at that time are sufficiently, you know, economically underdeveloped that there’s a strong incentive for young men to go join the army ’cause, you know, it’s a living.

And so Illyrians become, like, kind of the backbone of the Roman army, and they’re described as these, you know, tough Roman conservative types. I mean, these are, you know, these are, these are tough military guys. I say that to draw a contrast between, say, Hadrian, whom I mentioned earlier- … you know, who was a much more sophisticated, artsy, poetic, cosmopolitan emperor. Also a hard-ass. You did not wanna mess with Hadrian. But these guys from the third century are military men through and through. Like, their whole careers are, are in the army. And they have, like, the military stubble. They’ve got these thick necks. They look angry. They’ve got their hands on their swords. Like, they’re not projecting an image of sort of- … calm and sophisticated, you know, bum-bum, you know.

Anthony Kaldellis
Yep. So Diocletian gets a gang of them together. They, eventually there are four. We call this the Tetrarchy. And he basically allocates them to various… This wasn’t any kind of hard division of the empire. Basically, it was a collaborative project. They each went wherever they were needed.

Anthony Kaldellis
Broadly. I’d say more military zones. So the administration tends to operate, it kind of humming along in the background wherever these emperors happen to be, right? This is a, we’re talking about a period of big government now. So Diocletian creates a larger government, possibly a larger army, and in order to pay for that, you need more systematic and effective taxation- … which means you need more census, you need more bureaucracy, you need more collect… you know? So it is an era of bigger government.

So just to linger on that point- … is it fair to say that Diocletian created the deep state? Quote, “deep state.” So the tax collectors, the, the logistics, the thing that you’ve kinda hinted at, which is the separation of the civil and the military layer of society.

Anthony Kaldellis
So the concept of a deep state, I’ve had discussions about that with experts who work on the idea of the deep state, and I’m not sure that I would characterize the Roman Empire that way, in part because while you do have big government, you do have bureaucracy, you have, you have bureaucrats who are buried in various echelons, and you know, nobody knows exactly what they’re doing and things like that, I have not come across the idea of some sort of sinister elements, you know, who are working within the administrative apparatus to undermine the emperor. Like, from a distance occasionally, you might get glimpses of this kind of thing. Diocletian, for example, once complained that, “Nobody ever tells me anything.” In other words, like, he’s so removed-

Lex Fridman
Yeah, I think the, one of the ways to explain that is because, so, you know, in the modern day, democracy in quotes, there’s a kinda temporary nature to the leader at the top. So it’s incentivized the deep state to form. That, so the deep state thinks of themselves as a thing that propagates long-term periods of time, and then the leader is a very ephemeral short, short-term thing. With a, with an emperor, technically- … you can go for a long time, so it’s best to be integrated deeply. With, the bureaucracy should be integrated with the leader. It makes sense.

Yes. So Diocletian creates these larger bureaucratic structures, and these are the ones that define the society that I study. So as a specialist, I focus on the period after him mostly. But he implemented those to solve a lot of these problems. He was mostly successful. So in terms of generating revenue from a much more troubled and kind of precarious situation in sustaining large armies and putting down these rebellions and usurpations. And he was generally successful at doing that. So he created the model that they kept for the next, well, three centuries or more.

But a lot of the elements of that model lasted even beyond that, right?
But a lot of the elements of that model lasted even beyond that, right?
Anthony Kaldellis
Yeah, like universal taxation. I’ll give you an example. Up until then, Italy was exempt from taxes. Italy was the land of the conquerors. The conquerors don’t pay taxes to themselves. The conquerors live off the taxes that others pay, right? So Italy was this big tax haven, right? Diocletian, Galerius, you know, his guys, these guys are from Illyria. They’re from the Balkans.

Anthony Kaldellis
Like why is Italy tax-free exactly, you know? That doesn’t make any sense. It’s a very, very wealthy, prosperous part of the world, and so, no, they tax Italy. So now, like, not only do all Romans have the same citizenship and the same law, they all have the same tax system, and the Diocletianic tax code, as it were, it’s not a code, it sounds like a flat tax, which for us sounds regressive. But by those standards, by the standards of that time, it’s actually kind of progressive in a way.

So I mean, the functioning, the success, the flourishing of a society, the way the government works, the way the people are represented, all of it has to do, all the civil wars and everything, it feels like taxation is at the core.

Yes. Yeah. If you asked me to put my finger on one factor, it would be that.
Lex Fridman
So the taxation system, that feels like the early framework for the East Roman Empire.

Anthony Kaldellis
It did create a more sort of homogeneous framework, for sure. By the end of the third century, it’s pretty much in place. What Diocletian does is a universal census, and this is continued by his successors. So every taxable asset in the empire is censused. And so you can now start to have a budget.

Lex Fridman
Now, there is some element, and then you push back against that, some element of Diocletian where he legally limited social and class mobility in part for the taxation system, and made it, in many cases, illegal to move and illegal to quit your job. For example, as I read to guarantee the food supply and land tax, farmers were legally forbidden from moving away from the land they worked, so the state always knew who to tax. And then for soldiers, sons of veterans were legally obligated to serve in the army to maintain troop numbers. You argue that these were tax enforcement mechanisms, not a rigid caste system, and so in practice, the empire remained a society of high mobility.

This is a complicated matter. So let’s talk, for example, about soldiers. It’s probably the case that most soldiers’ sons were expected to succeed them. Like most professions where you have an apprenticeship, the son will usually succeed, right? There are a number of other professions that were kind of guild-like in nature, like, for example, shipping.

Anthony Kaldellis
Where there were considerable assets involved in order to secure contracts for insurance purposes for the ships and so forth, and it made sense for those assets to be, you know, passed from father to son. In other words, and with them comes the obligation to continue in that line of work. Some of these things are inherently sort of hereditary, and I don’t think most people would have objected to it. The farmers is probably the only case where it might have actually involved some coercion. There was a category of farmers, and we don’t know how many of them, who were, for fiscal purposes, bound to the land. This doesn’t mean they couldn’t leave the land, like physically. No one’s preventing them from leaving.

But they were fiscally responsible for providing the taxes or rents or whatever because the, the state wanted to have a secure revenue stream from, say, those lands. And if… Anyway, it’s, it’s one of these complicated situations. This did create some limitations on, on those people. And it’s a topic of current research, these bound farmers, as it were, who are tied to the land. It’s more of a… You know, someone put it that, you know, most of the time it’s people who own the land, and in this arrangement, it’s the land that owns the, that owns the people.

Oh, yeah. There’s tons of mobility. No, no, this is not a society where people are bound really to… We, like, we don’t find anybody who’s, who’s like, “Ah, I really don’t wanna be a soldier. But my father was a soldier, and I’m obligated to be one.” Like- … like, we just don’t hear those kinds of complaints- … of people who don’t wanna be a so- Why wouldn’t you wanna be a soldier in the Roman Empire? I mean, it’s got tremendous perks.

So can we just linger on the why is it that Diocletian was able to stabilize the empire? It’s like, you know, the crisis of the third century really threatened to tear apart everything. So why did some of these things that we talked about stabilize?

Anthony Kaldellis
Well, Aurelian had already united the empire territorially.
Well, Aurelian had already united the empire territorially.
Anthony Kaldellis
So this is right before Diocletian. And what Diocletian did was put in place a system that reduced the number of rebellions. Simply by having four big guys with four armies, they managed to put out all of those fires, or most of them. And once you have stability, and he also beat the Persians, I mean, Galerius did, so starting to beat back foreign invasions, that creates a framework for economic stability. People need to, you know, if they’re going to invest in, like, land reclamation or expand production, they need to know that, you know, foreigners aren’t gonna come rampaging through, marauding through, you know, stealing their cattle and, you know, enslaving them and taking them off to work on agricultural farms in Mesopotamia. Like, they need to know this.

Anthony Kaldellis
Sure. So Constantine was the son of one of Diocletian’s colleagues, so he comes from within the system. And the system was actually designed to be non-hereditary. In other words, the senior emperors would retire, the junior ones would move up to the senior position, and then they would recruit two new ones. And they tried to skip the dynastic element. So, so it would be kind of, let’s just say, kinda meritocratic, not whose son, you know, you were. Constantine was a son. He was passed over, but the armies liked him. He was actually quite competent.

Anthony Kaldellis
And so there’s a series of civil wars among all of these successors of Diocletian, and Constantine emerges as the winner. There are periods when there are quite a few of them. There are, like, six at a time, but they gradually dwindle down to one. So yeah, it’s as long as you have the quarterfinals, semifinals, and then the, the final war, and Constantine emerges in 324 as the sole ruler of the entire Roman Empire. So that’s who he is. He’s, he’s definitely an insider, very, very competent general at civil war. And he gradually moves eastward. So as he’s conquering his rivals, who are often at times his fathers-in-law or his brothers-in-law, because these people all intermarry, and they have alliances, and they fall out.

Anthony Kaldellis
It’s one of those kinds of situations. He moves eastward, and by the time he defeats his last rival, an emperor called Licinius, in 324 he’s in the East. And Licinius had his headquarters, or one of his headquarters, at this town called Byzantium. Byzantium is a city right where Constantinople was founded.

Anthony Kaldellis
And it is at exactly the point where Europe meets Asia, so on the Bosporus. And it’s a very strategic location. It always had been, right? So whoever controls the straits of the Bosporus, yeah, we don’t need to explain how important that is. And Constantine decides to create a city named after himself, Constantinople, on that spot, Byzantium. So Byzantium essentially ceases to exist as a city and is replaced by Constantinople, AKA New Rome. So it’s pretty clear that right from the beginning, Constantine intended this to be a kind of branch office of Rome in the East, a kind of copy and paste of Rome in the East, and it’s a plan that his successors continued, right?

Anthony Kaldellis
Now, there are a number of other cities in this, let’s say, in the generation or two before this, that were also treated as sort of quasi-Romes. Basically, there was this historian in the third century who said, “Well, wherever the emperor is, that’s Rome,” right? ‘Cause emperors are now itinerant. They’re no longer staying at Rome. They’re mostly on the frontier, and Constantine is one of these frontier emperors. They will sometimes visit Rome, maybe once or twice, maybe once a decade, you know, something like this. So Rome becomes something that can be sort of copied and pasted in other parts of the empire, and a bunch of other cities get called, you know, a New Rome, an Other Rome, an Alternative Rome, My Rome. And Constantinople is the last and most successful of those.

Lex Fridman
So maybe can you speak geographically the importance of Constantinople? It’s an interesting place ’cause it- … when you’re talking about a land so large as the West and the East, with enemies, with threats from all kinds of different directions, the location where the emperor sits is important.

Anthony Kaldellis
Very. So look at Rome, right? So it’s right in the middle of Italy, right in the middle of the Mediterranean. Very safe location in a way, but it’s very far from the frontiers. And this is a period when emperors need to be with the armies, right? They’re not senatorial emperors who are sitting in Rome having meetings with senators. They are military emperors who are marching along the frontiers mostly with generals rather than civilian administration. So they’re doing their job. Like, this is the hard work. They’re slogging through the mud of winter campaigns, right?

Anthony Kaldellis
They’re not just sitting in a palace enjoying themselves when they could. But Rome just becomes inconvenient because of that. And if you look at Constantinople, it is kind of halfway between the Danube frontier and the Euphrates frontier. So if you want to prioritize the East or treat it as an equal part of the Roman Empire, as these emperors all did. In fact, almost all emperors who had a choice about whether they would stay in the East or stay in the West chose the East. There’s only one who chooses the West, and that’s Valentinian later in the fourth century. All the others understand that the East is where it’s at. And Constantinople is right between the Danube and the Euphrates. These are two major frontiers. And so it allows emperors to move between the two.

Anthony Kaldellis
And also look at its location: north, south, east, west, right? So north, south, it is the node between the Black Sea and the Mediterranean, right? And east, west, it’s precisely where Europe meets Asia, right? And because there’s a break there, so there’s a Bosporus, the Sea of Marmara, the Hellespont, the Roman Empire during the civil wars, it would tend to break there.

Anthony Kaldellis
And you would have one emperor on one side in Asia, and you would have another emperor on the other side. And this just kept happening. And Constantinople ultimately functions as a kind of clamp that unifies this whole area, so basically the Balkans and Asia Minor and Syria as a kind of unit, right? And, you know, what is a new Rome? A new Rome is, among other things, a new senate, right? And Constantine and his successors recruit this new senate for the new Rome. So we’re talking about maybe two and a half thousand, 3,000 men, you know, at, at, at its peak, and these are all recruited from all of these areas. You know, some come from Rome, but others come from the Aegean region, from Asia Minor, Eastern Mediterranean.

Anthony Kaldellis
So these are the wealthiest people, usually most well-connected elites from the whole Eastern Mediterranean, and they come together and form a new purpose, common purpose in Constantinople. And the empire never breaks there again. Right? So it, it holds together this part of the world. The breaking point now, interestingly, moves to the Adriatic, right? So when, in 395, we talked about East and West kind of splitting.

It breaks at the Adriatic ’cause Constantinople is now holding that whole Eastern world together. ‘Cause all of these elites, they now, they’re invested in it. They’re literally investing in it. They have to invest in it in order to be senators in Constantinople. So that’s kind of one of the functions that it, that it performs, a strategic function. There’s a political function. There’s also a cultural one, but you know, we can talk about that, too. But that’s what you see there on that map, the northwest, east, south.

So just to linger on it, so you, you do a podcast, Byzantium and Friends, but you’re also a guest on podcasts, and I should mention you being a guest multiple times on the excellent The History of Byzantium podcast hosted by Robin Pierson. I highly recommend people listen to it, to all of your appearances. You have a lot of really fascinating ones. But the reason I bring all that up is, one of the episodes, you do the fun thing of selecting the top 10 emperors of Byzantium, and spoiler alert, everybody should go listen to the full list ’cause you justify all the different options. But Constantine ends up in the number one spot. And so can you just add a little bit more depth why he would be in your number one spot- … now that we’re talking about him?

Can you actually speak to the murderous aspect? He seemed to have murdered a lot of people in his family.
Anthony Kaldellis
Yes, that’s because what we call his family were also alliances of convenience that he made on the way to the top. And when those alliances or, you know, those, you know, those wives or those fathers-in-law were no longer convenient or, or turned against him, he had no hesitation in removing them. But he’s also, you know, he gets a, a little extra bonus because he also murdered his own son, Crispus, who was- … apparently a very competent and popular kind of general, and we don’t know why. He executes Crispus soon after defeating Licinius, and then follows it up with the murder of his wife-

… not Crispus’ mother, and we don’t know why. The funny thing is that when emperors do this sort of thing, if there’s any kind of remotely, like, a good reason, they’ll blast it through all of the media, right? Like, “Crispus was rebelling against me,” or whatever. There’s nothing. He doesn’t even try to justify it, which means it must have been something unjustifiable. Like, I don’t know. I can’t process it.

Lex Fridman
Yeah. Actually, as another side to a side, I think you mentioned whether it’s on your podcast or elsewhere, that if you had to have a beer with any of the emperors, you probably wouldn’t. So it’s not like some of the most impactful, some of the most influential and great emperors that we talk about, they might not be very pleasant people.

Anthony Kaldellis
Right. So let’s set aside whether you’d like to have a beer with these people. The reason I put Constantine at the top of the list is because the decisions that he made were so consequential, just important, and for the most part, not bad decisions. So I couldn’t not put him at the top of the list. The, you know, creating Constantinople and converting to Christianity and setting the empire on a path to conversion, these are major, like, world history level decisions.

Anthony Kaldellis
Right? Now, not many emperors do that. In fact, Constantine is in, like, his own league when it comes to those kinds of decisions. My other criteria for top emperors were basically those who did the job well, right? Not making, you know, these kinds of earth, you know, shattering decisions or, you know, world history changing decisions, but just who performed the role competently with results that impacted the lives of their subjects for the better. So those are the other criteria that I used. It’s difficult to juggle these different criteria, right, in order to create a systematic list. And by the way, we, historians, generally don’t do these kinds of things. But you said it’s fun.

Christianity in the Roman Empire
Lex Fridman
So you mentioned Christianity. That was one other big component of his rule. What was the role of Christianity in Constantine’s life, in the lives of the citizens of the new Roman Empire?

Anthony Kaldellis
At this stage, Christianity doesn’t have a role. It actually took the emperors… When the emperors took it on board, that is, they made it a part of the imperial system, then it began to acquire a role within the system. Previously, it had imagined itself as having its own history, like not necessarily part of the empire or affiliated with imperial power. But after Constantine, it does acquire a role.

Lex Fridman
And so actually, one way to ask that question, which is fascinating, ’cause you said that there’s like, there’s Rome, and then there’s like cultures or traditions like Christianity or being Greek, that kind of thing. So one of the ways to ask this question is: does Christianity triumph over Rome, or did Rome capture Christianity?

I would lean more toward the second. In other words, that the religion was co-opted by the imperial system. Now, there are many areas in which that’s not the case and where the opposite happens, so I’m not gonna be absolute about it, but I think it’s very important to recognize that because Christianity generates this narrative of triumph— … right, which modern historians perpetuate, and it’s framed in very particular ways. In other words, that Christianity triumphs over the ancient religions.

Anthony Kaldellis
Right? So displacing Zeus and Apollo and all of that, and animal sacrifice is gone, and like, that’s because Christianity triumphs, and that’s a very narrow way of looking at it. In other words, you pick your enemy, and then you can defeat that enemy, right? But if you look in the other direction, there’s, like, the Roman imperial state, and you cannot say that Christianity either triumphed over it or even tamed it or anything. It actually became part of it.

In many ways that, you know, determined its history for centuries and, in fact, down to today. So this is very different, for example, from the history of Islam. So Islam comes into existence without a preexisting state to receive it and take it on board. It creates its own state, right? So the Muslim armies, they conquer this empire, and then they have to sort of govern it. They think according to whatever Islamic principles. The Quran doesn’t say anything about running an empire.

So that creates a completely different society, right, where, like, Islam is really a primary kind of identity and, like, drives a lot of developments. But Christianity comes into existence within a very well-developed society and political system. Now, here’s the thing. We don’t know exactly how many Christians existed in the time of Constantine. Well, we speculate maybe 10% of the empire. That might be very high, right? But even if it’s 10%, it’s not a lot, and these are not, like, elites for the most part. Maybe middle, you know, what we loosely call middle class, a few elites, a few slaves, like this kind of thing. Mostly urban, and keeping in mind, most of the population is rural.

So Constantine’s conversion to Christianity and moving the empire towards Christianity is not something where it’s a gigantic majority of the people— … or it’s a political convenience because it’s the elites. It’s something else. I mean, it’s a pretty revolutionary decision, I would say.

Exactly. Now, there used to be theories that Constantine did this for, like, pragmatic, cynical reasons, that he, like, wasn’t a true Christian or anything, but there was some kind of political gain to be had here. But I have never read a convincing account of what exactly that political gain is. We now know that there are fewer Christians. They were not that influential. You can make an argument that bishops are a kind of convenient social influencers, you might say. Like, you can use those. They’re not a threat to your position.

Right? So a bishop is not gonna try to take the throne. So they’re not dangerous political operatives in that way. But they do have some influence over sectors of society, and so that might be a… Okay, I see that, but I don’t quite see the argument for, like, going full Christian just to get the support of some bishops, who actually pretty quickly turn out to be, some of them, more trouble than they’re worth. Anyway, so I have not yet seen a convincing political argument for Constantine’s decision, which means that you then fall back on a personal explanation that he did this because he was a believing Christian, right? And he came out, you know, in support of the religion that he held, and that’s kind of where most scholars are today.

Anthony Kaldellis
Though, I gotta tell you, historians are very uncomfortable about personal choice, like explaining history in terms of these kinds of personal choices. Because Constantine’s conversion is like, it’s massive. It opens the door. It incentivizes so many people to also convert.

‘Cause Romans will generally do what their, you know, rulers will tell them. If we’ve mentioned Hadrian a few times, Hadrian had this lover, Antinous, Greek boy from Bithynia, who died in an accident in Egypt, whatever, and Hadrian said basically that Antinous should be regarded as a god throughout the empire. And he was. We have, like, more statues and busts of Antinous from all of these temples all over the empire than I think of anyone else except Hadrian. So yeah, if the emperor says, like, “This is a person who’s a god now, you know, put statues of him everywhere,” they will. And when Constantine comes out in favor of Christianity, you know, suddenly people discover that, oh, this is an interesting rite. It’s got the support of the emperor.

So one of the things here, going to the Perplexity, Constantine’s conversion to Christianity is usually dated to 312 AD linked to a visionary experience before the Battle of the Milvian Bridge. Do you believe that vision, that he had this religious experience before the Battle of the Milvian Bridge? Here it says, “But historians debate both its nature and its sincerity.”

Before we even get to the sincerity— … is the problem of the sources. This is reported by authors writing later in the aftermath of a victory when the emperor… Like, one of them had a dinner conversation with the emperor a few decades later, and he said, “Well, let me tell you about the Milvian Bridge.” And it’s like, okay, I’m not gonna believe that. I’m not gonna take that at face value, rather. It’s a much more complicated… You know, this is how the emperor wants things to be remembered.

Anthony Kaldellis
That’s different. Also, Constantine tended to have a lot of religious visions. He had had religious visions of Apollo before Christ, and we have sources that talk about that, too, that he went to this temple in Gaul, and Apollo appeared to him in the form of light. Okay, Constantine has a religious vision every time he kind of wants to shift policies and his, like, profile. Like, when he wanted to break away from his other emperors who used to go for the—like, they went for this kind of Jupiter/Hercules model. And he shifted to an Apollo model. This is a branding. This is emperors doing branding.

So we should say that, as you’ve described, Constantine is a pragmatist. He’s very pragmatic. But you’re saying it’s fair to believe, based on the evidence, that he actually converged towards being a Christian believer.

Yeah. It’s very possible, in fact plausible, that he thought the Christian God had helped him in battle. And, you know, for someone like him, that’s as good a reason as any to support that god.

But he was not, like, a hardcore Christian all the way through. He was a kind of a spiritual, religious kind of person. He thought about religions more generally and just converged towards Christianity as a good religion. He also had ideas about what a good religion is— … and what a bad religion is, that kind of stuff. So he’s thinking in this space.

Anthony Kaldellis
He’s tending not to be too explicit. Depending on the audience. So Constantine remains a pragmatist in the sense that he doesn’t want to alienate too many of his subjects, right? And so he’s sometimes a bit coy or elusive about what he’s getting at. When he’s talking to Christians, he will talk about Christ. He will mention Christ. When he’s talking to everybody else in, like, a general law, he’ll just refer to good religion. And it’s like you, like, you, maybe you know what I mean, right? But he’s not gonna, like, you know, come to Jesus. Right?

So even at the time when he’s, like, supporting the church, like, basically institutionalizing the church as an part—of the imperial system, but he’s also putting up statues of himself that look like Apollo in Constantinople, right? So the focal point of Constantine’s Constantinople is the Forum of Constantine. And in the middle is this very tall column, and it has a colossal statue of Constantine on top, gilded, enormous thing. I don’t know, like, eight meters tall or whatever. But it’s a repurposed Apollo. It’s even, it, like, visibly so. It’s naked. It has the rays coming out of the-

Constantine, or his successors as well, because this was a gradual process, and it takes a very long time. So let’s let’s put it into perspective. We probably can’t talk about a majority Christian society until maybe the 5th century, or early 5th— … mid-5th. We, we don’t have data, obviously. And we can’t talk about, like, a solidly Christian society until early 6th century. And by solidly, I mean maybe where the non-Christians are 10, 15%, right? So that’s a long time. That’s, like, five centuries after Jesus. That’s half a millennium. So we’re talking about a half-millennial process here. It’s, it’s very long.

Yes. So very slow conversion, maybe, maybe up to 10% tops under Constantine. Then obviously larger and larger groups join the church, even if only nominally, right? Until you get to the sixth century when you’re clearly talking about a, you know, mostly or overwhelmingly Christian society. A lot of this is just done through incentives and disincentives, right? So bishops are given funds with which to distribute, like, charity and help to communities in distress. They have lists of widows and whatever they support. Land is given to the church by the emperors or in wills so that they can engage in this kind of social policy. And then there are disincentives. So emperors pass laws that increasingly restrict the exercise of traditional religion.

And then they just gradually start outlawing it more and more, putting restrictions on, like, if you’re not a Christian, you can’t hold these high offices or you can’t… Your… There’s problems with your wills. So they gradually do it like that. And this is how you… Yeah, this is… And it works. It works.

Christianity developed in a number of ways. So it acquired a certain number of forms that were capable of appealing to different constituencies. In other words, there was an intellectual side to it, the sort of theology, the almost quasi-philosophical or engagement with philosophical schools that could draw in, let’s say, intellectuals. There is a public ceremony and ritual aspect where you can organize communities and cities to have processions or, like, have all these festivals that take the place of the ancient ones. You have a kind of, it’s not secretive, but it’s kind of this initiatory aspect where there’s this baptism and you learn a sort of creed, and you’re initiated into the religion with the prospect of a personal afterlife, right? And that appeals to other kinds of people.

There’s also ways in which it integrated itself into the court and the language of power. Also in the army, right? Soldiers now swear an oath to the Trinity, right? So it takes all of these different forms that enable it to position itself, you know, here and there and, you know, in the streets, in the court, in the armies, in the churches, in texts, in books. And so it has this kind of manifold diversity, right, that makes it very adaptable.

So in part, this is, happens when you have religions that make exclusive claims, right? Like, my beliefs are true- … and yours are by definition false. Not, not just wrong, but false and even kind of evil. Like maybe— … Satan put them in your mind to- … lead you astray, right? And this is inherently divisive. Like, it is. So there’s this paradox where Christianity, in contrast to, say, the ancient religions, is both far more polarizing but also far more powerful as a unifying force at the same time, right? So ancient religions tended not to produce this kind of conflict or identities, right, or wars or these kinds of things. And they could under certain circumstances, but for the most part, they were not drivers of history in this kind of way.

But when you have exclusive claims, then suddenly these very communities that are sort of consolidated and have this very strong identity, but you also alienate other groups— … that you then are in conflict with. So this is why I, for one, can’t come down on whether, you know, Christianity is more of a unifying force or a divisive force in the history of the Eastern Empire, because it’s both.

And, like, often they don’t know that they believed that until in retrospect, once they’ve had the fight and the winner has this position, oh, now that turns out to have been the position we always held, right? And this happens again and again and again. You know, a lot of the time, these Christian theologians who get into so much trouble and get branded as heretics and sometimes get sent into exile, they didn’t mean any harm. They often just were stating what they thought everybody believed.

And then when they blurt it out, someone off in Alexandria is like, “What? That’s heresy.” And then now you’re, now you’re in trouble. Now you’re getting into this fight, and you might win, you might lose. But, like, a lot of them were kind of sort of well-intentioned in that way, or they had no intention of starting a fight. But there’s always someone who wants to start a fight.

Lex Fridman
Yeah, I mean, sometimes the fights are extremely intense over things that I could see on the surface or, like, iconography. It’s like, it seems like a very subtle- … debate, like almost academic. And then a large number of people don’t see it as academic. They, they do see it like “the devil put ideas in your head that are—” … completely wrong, and it’s, it’s fascinating how that kind of division can emerge. I mean, the impossible question, and I apologize for asking it, but maybe just worthwhile to try to think about it is, on the grand scale of centuries of the East Roman Empire, is religion a constructive or a destructive force for the empire? Did it help it flourish, or did it hold it back?

… like every religion ultimately thinks it’s orthodox, right? That’s– But that’s the conventional name, right? Orthodoxy today might be called Greek Orthodoxy. And I mean, it’s such an essential part of the culture. It really is. I can’t think of the two of them inde… I mean, I try to because, as a historian, I have to test the models, you know, and try to see these things as independent of each other. But ultimately, it’s very difficult to disentangle them, and I would say that to the degree that this is a successful society historically, that its religion definitely contributed to that and played a role in it. Not without cost, right? It mattered to them. They valued it, but things that matter to you have a cost.

And, and they, they paid that price. They were willing to pay that price for it. For example, at the very end, they had to choose between Catholicism, Western rule, where they essentially have to compromise on their faith, or rule by Muslims, the Turks, where they would not have to compromise their faith. And some of them were explicit that they were preferring option B, because the Turks will at least respect our identity. Like, that’s a cost.

Yeah. But there’s other layers, like taxation and- … the, the, the functions of government- … that are connected to religion to the degree it interacts with the, the tax system. But it feels like that’s the engine of the society and, and religion is more like the cultural layer.

Yeah. So this is why I said that I try in thinking of the models that we use to understand the society, not to assume that religion is everywhere and for everything. Now, I have colleagues who do that, and I would disagree with them about this, but you’re exactly right. There are elements of this society that I like to see as their own thing.

Like the Roman identity, for example. It’s not the same as Orthodoxy. But also the operations of the state. Those are very pragmatic things, and you see them intersect with religion in, largely in areas of terminology or the vocabulary that they use or, you know, like at the top, but not at their actual functioning. So in my field, I’m a historian who’s tried to promote other aspects of the culture as having a kind of integrity of their own and not to subsume them all within Orthodoxy.

So, I mean, again, an impossible way of asking the same question. If you asked a Roman, a million Romans across a thousand years, “Are you a Roman or a Christian?” what would be the answer for that?

Well, they overlap. But if you were to… And this might be a somewhat more subtle conversation than most of them would want to have, but if you were to say, “Is Roman and Christian the same thing to you?” If they thought about it for a little while, they’d quickly be able to say no. Because there were, I mean, just logically, there were Christians who were not Romans.

Anthony Kaldellis
The Bulgarians or the Rus or, you know, whoever. There were lots of Christians who were not Roman, and they did not regard them as Roman just because they were Christian. Conversely, they knew perfectly well that there had been Romans who were not Christians, and they knew this how? Because in the churches like almost every week, they celebrated martyrs who had been killed by the Roman emperors in the past. And so it was, like, the performance of violence by Roman emperors against Christians was, like, something they remembered. They knew perfectly well. So those two things did not overlap perfectly.

And there were some contexts in which you would be more Roman, and there were some contexts in which you would be more Christian. And you find characters who, and I love to do this. I find characters who as some sources say didn’t pay too much attention to Christian things. Like, they were just politicians. They were just doing their work. And then you find characters who, like, devote themselves. They go all in on Orthodoxy and, like, monasticism. They just don’t care about the Roman stuff at all.

And that is, in fact, part of the reason why I like this society, is because it has these kinds of options for people to choose. And there’s another one. There’s the Greek stuff, too, because their language is Greek, their literature is Greek, and so there are people in the society who go all in on the Greek stuff. Right? And I see this society as this kind of laboratory of these three elements coexisting in these fascinating combinations. Usually it’s combinations, right? But sometimes you’ll find people who are like, kinda try to be purists in one way or another. And it’s the only society in history in which you can do this, ’cause it’s the only society that’s Roman and Christian and Greek. But in different ways, right?

Yeah, unfortunately, I think it’s tempting, but it’s probably impossible to say if we remove the taxation system, would the, would the Roman Empire be more or less successful? If we removed religion, would it be more or less successful? If we removed Greek and kept it Latin all the way through, would it be more or less successful? It’s probably impossible to do this kind of analysis ’cause they’re all so deeply integrated.

But there is a big temptation, and this is at the core of your work, to understand why did the East Roman Empire last as long as it did. And why did the broader Roman Empire last as long as it did?

How did it last so long? A lot of your work kinda hints at it. It’s here and there. But you’re trying to do more systematic. So, and we’ll keep hinting at it. But to put a bow tie on Constantinople, it went from a very low population of maybe 25,000 people to 500,000 people in just two centuries. So can you explain how that happened?

Well, it didn’t happen through just demographic growth and reproduction in the city itself. That rate of growth is impossible for an ancient city. So when I say 20,000, 25,000, that’s possibly what the ancient city of Byzantium had-

… when Constantine decided to found Constantinople, and it grew to a city of a half a million in two centuries. That can only have been done in one way, and that is immigration from the provinces. So people must have been moving there in large numbers, which is a movement that we can’t see very clearly in the sources, but we have to infer it and then try to explain it. So also there’s another factor, which is that ancient cities we now know or suspect are what some historians call death traps. In other words, the density of disease is such that ancient cities probably are losing something like 1, 2, possibly 3% of their population per year. So just in order to stay with a stable population, they have to import people.

Oh, yeah. Now, you know, Roman cities have some corrections for these sorts of things, like the way they distribute the water through the city. Anyway, they, they weren’t as bad as they could’ve been, but there’s that. So not only to keep the population steady, but to expand it so dramatically means that a lot of people are coming in from the provinces, mostly the Greek-speaking provinces. So, you know, Greece, Asia Minor, and some of the major cities in the East that are Greek-speaking. And I start to wonder, like, well, how did this happen? Like, who are these people, for one thing? And then I did some simple calculations. So I mentioned earlier that we have something like two and a half thousand senators-

… Who are required initially to reside in Constantinople. Well, senators don’t live in bachelor pads. Senators have manors. They have household staff, right? In Rome at the time, there’s a calculation that a senatorial household was something like 100 people, right? Just servants, slaves, dancing girls, cooks, barbers, whatever, right? So let’s assume sort of conservatively that in Constantinople it’s only 30 people, which might be low, right? So if you do the math, you’re starting to get something like, I mean, closer to 100,000 people, right? And that’s just by bringing in senators.

As we talk about diverting resources, slowly the West declines and collapses in 476 AD. So the Visigoths sack Rome in 410 AD, and in 476 AD, the last Western emperor is deposed, marking the end of the Western Roman Empire. High-level question: What is the reason for that decline and the collapse of the Western Roman Empire? So nonstop civil wars, as we’ve talked about, weak emperors. There’s an economic money crisis, so shrinking tax base, rising army costs. There was a loss of key provinces, especially in North Africa. Reliance on contracted barbarian troops as they immigrated more and more into- … The Western Roman Empire. Cascading invasions, migrations amplified by Hun pressure, and then the East-West split. The richer East survives, the West can’t stabilize under- … that split.

Anthony Kaldellis
Yeah. The crux of the matter is that barbarian armies, so armies from outside the empire, put increasing pressure on it during the fifth century. And for whatever reason, when the Roman state failed to sort of suppress one of them and, say, settled them here or allowed them to have here or couldn’t stop them and they took over a province like the Vandals did in North Africa- … this created this kind of vicious cycle because then the Roman state lost access to the resources from those provinces, that is the taxes, and without those resources, they couldn’t, you know, maintain, mobilize, pay for their armies.

Anthony Kaldellis
Then they had fewer armies to handle the next wave of barbarians that came in. The previous barbarians who settled kind of declared their kind of independence. They also could not be put down, and so this created a vicious cycle that just continued in that way. It’s not rocket science, actually. I mean, you can see it playing out. Yeah. Now, who these groups are, where they came from, why did they cross, that, that, those are different questions, right? But from the Roman standpoint, that’s how it was experienced. These are armies that can defeat a Roman field army-

… right, in battle. And sometimes they do. And they then settle and take over territories, and then you lose the revenues, and so you can’t recruit your own armies. And so, anyway, that, that’s the kind of cycle. The East tried to help. Occasionally, they would send forces, but they were also subject to some of the same pressures. ‘Cause remember, the Goths cross the Danube for the first time in a major way in 376. Then you have the Battle of Adrianople a couple years later, where, like, one and a half field armies is just annihilated, and the Emperor Valens dies, and the Goths are just, like, kind of loose in the Balkans. And there was then a long war with them, four years.

It results in a kind of truce where neither side wins, and the Romans, for the first time, accept the presence of this quasi-independent Gothic army in the territory of the empire. This is unprecedented, as I said, and it creates a lot of tensions and dysfunctions. Okay, so why does the East survive and the West does not, right?

Anthony Kaldellis
There’s… And so… Lots of reasons that we can give here, but one of them is the geography that we were talking about earlier. In other words, without a fleet, which they don’t have, the Goths can’t cross over from Thrace or the western Balkans to Asia Minor and go plunder some of the more prosperous provinces. So they’re stuck in the Balkans. They’re gradually pushed kind of in toward the western Balkans, which is, like, the worst part, you know, at the time, like, you wanna be in. And eventually, they just decide, “Well, you know, it’s kinda nicer in Naples.” And so they go to Italy, right? Just because there’s just a lot more resources there for them. And that’s one way that the East just kind of manages to…

So that’s one. So geography is some of it’s sort of the luck of geography and- … both of the invaders and the geography of the empire. But, you know, the, the East had a lot of invaders since- … and was able to still barely at times- … survive the invaders, so… And some of that could be luck. Some of it could be about the nature of the invaders and the effectiveness of their military, all that kind of stuff.

Anthony Kaldellis
By the way, it worked in the other direction, too. So if you have, like, Persians or Arabs coming into Asia Minor from the East, they usually can’t cross over into your Balkan provinces. So you can fall back on one side or the other side. They… If you fortified Constantinople so that it’s an impregnable bunker, which it was, right? So you, you’re holding your command center in Constantinople. You can alternate between your European or your Asian provinces, depending on where the trouble is. You can call in reinforcements from either side. So the East does have that kind of advantage. This is not the reason why it survives for as long as it does, though it is a reason. You know, also, they acquire flamethrowers at some point, which- … those help, too.

So you can fall back on one side or the other side. They… If you fortified Constantinople so that it’s an impregnable bunker, which it was, right? So you, you’re holding your command center in Constantinople. You can alternate between your European or your Asian provinces, depending on where the trouble is. You can call in reinforcements from either side. So the East does have that kind of advantage. This is not the reason why it survives for as long as it does, though it is a reason. You know, also, they acquire flamethrowers at some point, which- … those help, too.

Right? Ultimately, I think it’s the decision made by local communities to stick with the Roman state, like, ultimately. Like, they’re not going to actively side with invaders. And when the trouble passes, they restore communities with Constantinople immediately. Like, this is their natural political home. And, and that’s the question that I’m really trying to answer, like, why does that happen?

You know, we should say, just, just like we’ve articulated multiple times, that it, the Roman Empire survives- so it’s not like the Roman Empire collapsed and another Byzantine Empire was born. Really, there is a shift that happens, and part of that shift is because of Constantine, right? It’s not just about where the capital is, but I’m sure that there’s just a general move towards that direction from the West to the East. And, and that in many ways, you know, weak emperors and, and the West, the weak leaders, the structure of government, all these kinds of elements put together- … maybe demographic shifts and declines that have to do with the fact that the center of the empire has moved. And so ultimately-

It’s quite striking. So for example, already by, like in the 430s, Constantinople is basically codifying Roman law for the West. So Roman law in Latin is codified in Constantinople, and then sent to the West as, “Oh, here’s your law code.” And this is in the 430s, so after the alleged division between the two, which like I said, is kind of loose. It’s not hard and fast. In the 6th century, it is the East that reconquers part of the West under Justinian.

And not only that, he also recodifies Roman law on a much bigger scale, and then that law becomes Western law. So in a certain sense, Roman law as we know it comes from Constantinople. It doesn’t come from ancient Rome. I mean, ultimately it comes from ancient Rome, but we don’t have those versions of it. We have the East Roman versions of it. It is East Rome that reconquers Rome. This is a funny inversion, you know, because Constantinople is situated in a province, Thrace, which always was sort of considered backwards, right? In the time of, like, the early Caesars, if you were in Rome and you thought, you know, Thrace, it was like, “Ugh.” It’s like, you know, some sort of, yeah, armpit of the Roman Empire or something, you know?

But by Justinian’s time, it’s complete inversion. Like, the capital of the Roman world, the heart of it is there, and Rome is this kind of backwater provincial city in Italy, you know, that you’ve just liberated from the Goths, and it’s kind of in ruins. There are wolves roaming the streets of the Forum. So this is a complete overhaul of the centers of power. It’s turned inside out almost.

And I think it’s fair to say that the reason the East… Part of the reason the East lasted as long as it did is the topic that we’ve mentioned, which is the structure of government. So can we just zoom out once again and explain the key ways the government functioned in the East Roman Empire, and how it evolved over the lifetime of the empire?

Very broadly speaking, there’s civilian and military, right? And you might actually add the church. It’s entirely plausible to treat the church as a kind of government institution at this time. But let’s just stick with military and civilian. The military is pretty straightforward, would be recognizable to any student of military history. This is how you recruit, organize, equip, pay, and lead soldiers. And the East Roman state tends to have a larger military, at least paper strength. Active is a different matter. Like, how many soldiers you take on a campaign is a different matter, but how many soldiers you maintain, like, in the provinces generally, right, is a… It tends to be on the large side for a medieval society, right?

So it compares favorably to, say, the Caliphate later on, which is a much more massive territorial entity. So the military is that. It can have anywhere between 100,000 at a minimum, at a low point, up to maybe about 250,000 at a high point, depending on the period. It’s a lot of people. It’s a lot of men. Factor in their families, right? These are also, like, part of the whole, you know, military economic complex, if you will.

And so then you have the civilian administration. Civilian administration does a number of things. Principally, it is to find the funds to pay for this army, which is the single largest expense on the state budget, right? And so in order to find those funds, it has to have a census of the assets, and it has to be able to tax them, and there are lots of different ways of doing that. So the civilian administration has a number of tax bureaus, record-keeping, this sort of thing, also a legal branch for resolving disputes with the imperial fisc. Okay. But the civilian administration does a number of other things, too.

And then there are a number of endowments that, you know, major churches, Hagia Sophia, for example, has hundreds of staff, clergy to, you know, readers to whatever, and so they need to be paid, and so you need endowments.

Yes. So this happens in East Roman society too. I’ll give you some examples. So there’s not a tax code as such, but what you— The way it operates is through basically exemptions. So you petition for an exemption. You might be a monastery, you might be a wealthy— You might be someone well-connected to the court. You might be a struggling provincial village, and you petition the emperor or some official, and you say, “Hey, we know we had a bad season,” or, “The barbarians came through and they took all of our… We can’t pay the taxes. Could we have an exemption?” And emperors often are granting these exemptions for very specific things, like maybe for this year or for that tax or whatever.

Anthony Kaldellis
The problem is that the emperors are discovering every once in a while that their officials are granting these exemptions sort of on their own. So every once in a while, the emperors have to, like, clear house when they have to, like, cancel all of these exemptions and start the whole process again. But later on, once we start to have documentation, like maybe in the 11th century, we see that every little—well, not every, but we have all these monasteries, these little villages, these high officials, and they all have these documents that give them exemption from this or that or the other thing, and it gets so complicated, and that’s how it works.

The eunuchs are part of the household staff of the emperor. So that would be like—what would it be? The West Wing of the White House or something like this. So they are the people who handle the imperial person, the bedchamber, the organization of palace life—things like banquets, you know, these kinds of things—the wardrobe. And why are they important? So for, for starters, if you’re, like, physically with the emperor all day, right? Like, you’re handling the meetings, you’re… Right? People can come to you and say, “Hey, I need you to put in a good word for whatever,” right? So they can get things done. So you, you bribe them, they get things done. So they’re very useful in this way. They’re also kind of hated for that reason.

… for solving all the problems, for dealing with petitions and exemptions and whatever. Like, they can do it. So where’s your power exactly? So what the emperors did not want is to be displaced or overshadowed by these kinds of more impersonal institutions. And so they would often set up parallel tracks of power. So this could be a bit confusing. So eunuchs were perfect for this reason because often their origin was from outside the empire, or they were former slaves. They weren’t connected to, like, networks of powerful families.

So you knew that they would generally be loyal to you because they depended entirely on you, the emperor, for their position and their power. And what you would sometimes do is you’d say, “Okay, I’m putting you in charge of, like, this army.” Literally, like putting you in charge of an army, just so that you can counterbalance the kind of networks of established generals, and you’ll have, like, no, a eunuch from my wardrobe. You know, I’m putting him in charge. And so this kind of shook things up a little bit so that people who were part of a system or a network could never fully count that that could get them all the power that they wanted. They now they have to answer to this eunuch from the wardrobe who’s, like, outside of their system.

In some parts of, like in Caucasia, there were some regions that were famous for producing eunuchs, also in, in Persia and so forth. But also, we are pretty sure that this happened within the empire, because there were some families that, like, really wanted to place a eunuch at the court. So from Paphlagonia, there were a number of… This is in northern Asia Minor. And so they would… It was almost like a family strategy.

These people do not exist, these isolated peasants. This is a myth that I, one day I’m gonna write a chapter about this because it’s this idea that you occasionally encounter, well, actually quite often in the scholarship, that there are these sort of rural communities out there somewhere that don’t know what’s going on in Constantinople. They might not know, even know who the emperor is. They’re cut off. Maybe a tax official will show up every once in a while, maybe not, and they just live their lives on their own, unaffected by the, say, state, because the medieval state, we suspect, is, you know, always powerless and can’t, you know, affect people’s lives. There’s no proof for these communities at all.

At most, you might try to find some, like, actual hermits, like, actual Christian ascetic hermits who try to go out and find this situation, and sometimes they’re described in the text as, like, oh, so-and-so went so far out into the mountains that, like, not even the tax census people showed up there, which, which tells you how they think about what it means to be isolated, right? So this is not a… This is a state in which every arable piece of land has been censused for centuries. It’s not like you can hide a village, right? And the taxation process is not like, what, they visit once a year, give us some coin, and we’ll leave. It’s actually more like three times a year.

And the taxes are not just coin and maybe a payment in kind or something, but it’s, it’s a whole bunch of things like services and recruits and all… You’re right. And once you start adding all of these things up, it creates a very dense institutional matrix in which all communities are enmeshed.

They can’t get out of it. Also, they, they have a church, don’t they? And if they have a church, they have the calendar. And of course they have the calendar because… So, like, how do they organize time and space and boundaries and all of these things? No, this is all state institut- How do they pay for anything? They have coins. Coins are everywhere. So I think that these institutions structured the way that everyone, even in village communities, even in the most isolated ones, supposedly, how they thought about things like time and space and value and relations and power and kinship and so forth.

So one of the things I briefly mentioned just would be nice to elaborate on is this term of monarchic republic. So we’ve been throwing around words like kingdom and republic and empire and monarchy. So what is the actual… What’s a good applicable term to what this thing is- … the East Roman Empire?

Anthony Kaldellis
That’s an excellent question, and I’m glad you flagged that because we call it conventionally Byzantine Empire, and it’s neither of those things really. We talked about Byzantine. Now, empire’s a bit of a problem because first of all there’s no term in Greek, in the Greek that they use at this period, that corresponds to our notion of empire. It’s not part of the official terms. It’s not even… They didn’t even have a term for it. You could have… There’s some terms that might mean something like state, arche maybe or kratos. But for the most part, it’s either basileia, which we might translate as monarchy, or politeia, which is polity. And politeia in Greek, polity, is a Greek translation of Latin res publica.

Res publica doesn’t mean republic the way we mean it for the Romans, like a non-monarchical regime, right? That’s how we mean, like, the American Republic or, you know. That’s a usage that came in later, like during the Enlightenment. In Latin, a res publica is the common affairs, the common interest of a people who are constituted as a political community, regardless of the type of regime that they have. Like even Cicero could imagine the Roman res publica governed by a king or by a senate or by a democracy. And they continue to use that term. We don’t use it according to Roman norms. We use it according to modern norms, the term republic. So they continue to call it a res publica or a polity under the emperors as well, right?

And it was understood that the role of the emperor, whether he’s Caesar or basileus or whatever, whatever language, was to serve the polity. They keep saying this. So the terms that occur in the sources most commonly are basileia of the Romans, polity of the Romans, or Romania, which is the proper name of this state. Not empire.

Now, empire. Empire in modern English commonly, an empire is a state that’s created when one group conquers a bunch of others and rules them. It could be an ethnic group. It could be an ethnoreligious group. It could be a political group, whatever. But there’s an act of conquest, and results in a state where one group is ruling over others. That’s not how Romania is actually constituted. We’ve talked about this. It’s, for the most part, all Roman citizens ruling themselves—like Roman subjects ruling themselves through their own government. So it’s not an empire strictly speaking. Now, occasionally, they will conquer other people, right? We talked about the warfare. Sometimes it’s not just defensive. Sometimes it’s offensive, right?

In that case, you do establish an imperial relationship. Like we, the Romans, are ruling over this other group. Could be Slavs, it could be Bulgarians for a while, it could be whatever. Or even some Muslims in northern Syria for a while in the 11th century who—and you are not Romans. And that’s an imperial relationship. The question is, how many of these imperial relationships do you need to decide that, well, we’ve reached a tipping point, and now we’re just gonna call the whole thing an empire? Personally, I don’t think we ever reach that point. I mean, all states, even today, have like minorities. Some of them are part of that state because they were conquered once upon a time. But we don’t call those states empires necessarily. Even though…

I think there’s also a synonymous use of the word empire that refers to the power that the state has- … in the global context geopolitically. So sometimes empire is used synonymously with superpower, meaning it’s one of the primary- … nations in the world, and it doesn’t necessarily have to do with the imperial nature of its history.

Yes. Though you would never characterize the American political regime as an imperial one insofar as it does not have an emperor, for example. But anyway, yes. The problem is that in my field, we use the term empire conventionally, even when what you just described is clearly not happening, like even toward the end. It’s not a major world power. It, like, has a few islands in the Peloponnese, but we call it empire and the emperor, and it’s like, it’s completely ridiculous. There’s not even a term in their language for that sort of thing. Anyway, we can call things whatever we want, just so we understand what the reality is- … and what we are using those terms to mean. I think that’s the important thing. Yeah.

Also, the emperor was expected to be working for the republic. Like, they keep saying this. So, like, this was their conception. You don’t find it, for example, in other kinds of dynastic empires, the ones that don’t emerge from within the context of an ancient republic. So this is another reason why I find this civilization so fascinating, right? I mean, we mentioned the Greek and the Roman and the Christian elements that are kind of jostling together. This is fascinating to me in part because it’s this weird combination of monarchical power, like in terms of executive institutions- … and a republican kind of baseline ideology on which it operates. Yeah, and they, they sometimes come to a head.

Is there at all a degree to which it’s a military dictatorship? Because especially when it’s the general in the emperor’s seat, yes, there’s a republic, yes, there’s political discussion, but the army has a lot of power. So to what degree is it a military dictatorship, as is sometimes talked about when you talk about the Roman Empire?

Anthony Kaldellis
Yeah, so Augustus’ position, for example, and that of his successors is talked about as a military dictatorship. In other words, when push comes to shove- … and the basis of political power is the army, then I suppose it’s legitimate for historians to talk about a military dictatorship. But here’s why I don’t think the Eastern Roman Empire is a military dictatorship. Even though, again, the emperors control the armies and the armies themselves will often have a say in who becomes emperor, like through the civil wars that we mentioned. Okay. The reason why I don’t think it’s a military dictatorship is because they almost never, very, very, very rarely use the army as an instrument of social control.

As a way of keeping down the population, you just don’t see it. And part of the reason for that is I don’t think the population needs to be kept down. Like, this gets back to the consensus that we were talking about. The understanding is that the army is there to protect the Roman people. And is often recruited among them. And for most of the period that I study, lives among them. So when the emperors have to call up the army, they’re literally calling up soldiers from local villages.

It’s just incredible that this worked. I guess the civil war thing is, as a mechanism, is effective. ‘Cause you just, throughout human history, I mean, you look at even recent history, it’s just a very common thing for an authoritarian figure to use the army to suppress people.

Well, it’s a risk. Like the Arab Spring. Especially in Egypt. And you could, you could tell for those three weeks that Mubarak was trying to decide whether he could actually count on the army to suppress the protesters or not, because you never know what they’re going to do if you ask them to fire on a civilian population. It can backfire on you badly. So I think that is a very dangerous force to use, and even in the context of modern regimes, can result in a regime change.

Emperor Justinian and wars of conquest
Lex Fridman
Mm-hmm. Yeah, he gets wild. So let’s talk about Justinian. We have to. We have to talk about Justinian. One of the most impactful Roman emperors in history started as a peasant, and rose in power to become emperor. He fought wars of conquest and was very consequential and impactful. So who was he?
Mm-hmm. Yeah, he gets wild. So let’s talk about Justinian. We have to. We have to talk about Justinian. One of the most impactful Roman emperors in history started as a peasant, and rose in power to become emperor. He fought wars of conquest and was very consequential and impactful. So who was he?
Anthony Kaldellis
All right. So Justinian was the emperor from 527 to 565, so quite a long reign. He was the nephew of the previous emperor, Justin I, who was an older man, ruled for just under a decade before Justinian. And both of them came from small, poor agricultural communities in the western Balkans.

Anthony Kaldellis
Yeah, for one decision. He’s not the worst of the worst, but he made a very, very bad call when it came to church policy, tore the church apart. He shouldn’t have done that, in my view. But by the way, Justinian’s an immensely complicated figure. I found it impossible to decide, first of all, whether to put him on the best emperors or the worst emperors.

Lex Fridman

Anthony Kaldellis
And through all the systems of social mobility that we’ve been talking about, Justin ended up emperor. Because of his military background, he just rose through the ranks. He was in the right place at the right time, became emperor, and then he gradually positioned his nephew, Justinian, whose background we do not know. Literally, we do not know anything that Justinian did before the age of something like 38 when he appears on the historical record. Same background. We know where he came from, but we don’t know what he was doing, although, like, was he an active soldier for decades? We don’t know. Probably not. He comes equipped with, like, a knowledge of something like Roman law and some Christian theology. That seems to be, like, what he knew.

And then Justin positions him to become his successor eventually, kind of reluctantly, but he does. Justinian also marries Theodora, who’s a woman who’s a former sex worker, which is a controversial choice. By this point, he’s a senator and is holding all of these top generalships, and then he becomes emperor.

Under his, yeah, during his reign. So the interesting thing about Justinian’s choice of, let’s say, associates, and that includes his wife, is that he seems to have just gone for people he thought were talented- … or that would be good for him as a ruler, rather than their social class or prestige. And so he accumulates around him quite a motley group of odd, sometimes like these kinds of disreputable people. But they did what he wanted them to, and they were—they—with lasting consequences for world history. So he has an eye for talent, and he doesn’t hesitate to pick people that others might look down on if he thought they could get the job done.

And this was a massive work of codification, and it is our main source for Roman law. Like overwhelmingly, what we call Roman law is what Justinian’s committee, and specifically this character called Tribonian, who was a very accomplished jurist, said it was.

Well, I mean, Roman legal concepts pervade everything from philosophy to political thought to actual Roman legal practice. I mean, depends on what country you’re in. So in many of the countries of Europe, it is the, you know, current law. And it is to some degree. I mean, I’m exaggerating. But legal scholars have to study Roman law. Even law students have to do that. Not so much in countries like the United States or Britain, which have the so-called common law system. But ideas in Roman law about, for example, property, right, ownership, things like this, these were hugely important in formulating ideas, for example, about sovereignty in political thought. Yeah, it’s one of the most important and influential acts of committee work ever done in Constantinople.

So going to Perplexity here and looking at some aspects of the Justinian’s laws, they include a systematic structure of private law, persons, things, actions, strong protection of property and contracts, detailed family and inheritance rules, and a hierarchical status-based view of persons. These elements became the template for later civil law systems. And some overall structures, tripartite schema, law organized around personae, legal subjects, things, and procedural actions. Essentially who, what, and how of- … private law. And it goes on. I mean, a lot of the things I’m reading here really sounds like what we think of as law. Marriage.

Marriage is a legal status. Lawful matrimony required conformity to rules about age, citizenship, and cognatum or prohibited degrees, incest rules, adoption relations, et cetera. All that kind of stuff.

No, for him, no, for… So for Christian emperors or Christian authorities, this is a reprehensible, immoral act. Depending, it could be punished. Justinian did try to punish it pretty brutally. I mean, ultimately lethally. However, this gets really tricky here because what counts as a homosexual act is not clear to everybody, right? And in addition to which, there… This is a society that generally will not go after let’s say scandals or deviance or however you wanna call it, like systematically. This is not like some– There’s no inquisition.

Anthony Kaldellis
There’s no social police. If there’s some sort of scandal and this comes out, then it’s a problem. But they’re not actively going to track down, hunt down, monitor, survey, interrogate people about their sex lives. I mean, it is in a way, despite having views that we may not agree with about sexuality, it was generally humane in the way of just kind of leaving people alone.

Anthony Kaldellis
He thought he was authorized by God to reconquer the lost provinces of the Western Roman Empire, and when he did so, that was proof that God favored him. And he was generally opportunistic about it and for the most part, kind of successful in that he intervened in the most critical moments of the histories of these barbarian, you know, kingdoms in the West, and exploited their weaknesses and took them over. Now, in the process, many of these provinces were ravaged by war—Italy for decades. He overstretched his resources, leaving his successors with a much more dangerous situation to defend. And he disbanded certain armies that were meant to protect Constantinople, sent them to Italy, for example. This weakened the home front.

Anthony Kaldellis
So he left a very difficult legacy for his successors in that way. Plus, some of the provinces that he conquered were so—like Italy, I don’t think it could even pay for itself after a certain point. So I’m not sure that some of those decisions were the best ones. North Africa, yeah, probably that paid off. Italy and southern Spain, not so sure.

Conquest is not just good, you know, in itself. I mean, this is… I know that some rulers in history are called the Great simply because they conquered something. But that’s, no, that’s not enough. I mean, I know that rulers do this, but if we’re to compare them to each other, we should at least expect that they have a plan or that it works out well in the end, let’s say, and I don’t think that many of these did.

Right. Are you strengthening institutions that benefit your subjects? That. And some he did, some not. So look, in order to send those armies west to make the conquests, he stripped the east of armies, so the Persians could just march in and, like, destroyed Antioch. Like, that’s a major strategic failure, and I don’t think you get a pass for conquering North Africa by surrendering Syria.

Yes, after he and his soldiers set fire to it. Yes. In the Nika insurrection. So this is when the people of the capital rise up against him, and there’s, like, about 10 days of street fighting, and he brings in some armies, and eventually he orders his armies to slaughter the protesters, leaving more than 30,000 dead. Like, this is an enormous number. And a lot of Constantinople burned in the process, and yeah, he rebuilt it. So his building is considered one of his great points. He built Hagia Sophia, for example, which is a magnificent church, like, hands down. It’s just a fascinating monument to study, too. And yeah, that was, that was him, too.

Anthony Kaldellis
Yes. So this is a bubonic plague. Which lasts more or less for two centuries. It comes and it goes, and it’s kind of endemic to large parts of the world. 541 is when it starts to break out in the empire, in Constantinople and other cities, and it spreads. There’s been a lot of debate about this recently because now we’ve actually isolated the pathogen. It’s Yersinia pestis. Like, we know this. Just as of, like, a generation ago, this was just guesswork. But now there’s all of this new, like, laboratory science work that’s come in to fill in some of the gaps in history.

It is. It is. There are lots of discussions about that. And so the study of diseases and virology have just become much more important lately. It still doesn’t tell you, however, like mortality rates and historical impact. Like, for that, you still need standard old-fashioned non-laboratory historical work. And there’s a debate about the impact of this plague. It’s ongoing, I should say that. And some scholars argue for a kind of maximalist position of 50%. I think that would have brought this society to a halt. Just logistically speaking. And so I believe in a much more moderate impact.

Anthony Kaldellis
Oh. Oh, yeah. The tax base would shrink instantly. You wouldn’t be able to recruit armies. You know, there would be massive social dislocation. Like what happens in the Black Death in Europe in the 14th century. Like, we have very good records for what happened to those societies, and basically everything that they were doing stopped for a few years until they sort of tried to put things back together again. This does not happen in the 6th century. In fact, Justinian is at that time waging war on something like four or five different fronts. If you read the narratives of those wars, there’s no pause. There’s no impact from the plague on the conduct of those wars. They just continue on.

So what is the legacy of Justinian in terms of how he left the empire leading into the 7th century?
Anthony Kaldellis
Well, he left it overextended, so his successors had to deal with many more problems along many more fronts with fewer military forces concentrated in what we might call the homeland of the Eastern Roman Empire. And so that made the center vulnerable too, and so you start to get raids into the Balkans and, you know, it enters a kind of vicious cycle again. Now, not all of this was Justinian’s fault. I mean, the plague definitely had some impact. But I wouldn’t blame everything on his successors, as is sometimes done, like they mishandled the situation. He… Yeah, he left them a very difficult situation to deal with.

The Arab conquests

So speaking of which, let’s talk about Heraclius. He didn’t make, he didn’t make your list either, which is a shocker for a lot of people. Perhaps you can describe the nuance of that, but he took over the Roman Empire on the verge of extinction. Persians at the gates, treasury empty. So maybe first tell the full saga of the Roman-Persian War that threatened the empire’s existence.

Anthony Kaldellis
Sure. Well, he wasn’t entirely, you know, free of blame for the situation that he inherited. He was, he was in part responsible for it. So he doesn’t get a pass on that. So Heraclius is basically a rebel and a usurper. So for various reasons Rome and Persia are at war starting around 602. And the Persian shah at this time, Khosrow II, has basically decided on a policy of conquest, not just raiding. Like, I’m gonna go in and take your people, some cattle, and some statues, and take them to, you know, Mesopotamia. He starts what… I mean, I think there’s some evolution in his thinking and his planning about this, but pretty soon during the 600 and the aughts, he realizes that there’s potential for actual permanent territorial gain here, and his armies start moving in.

And the Roman Emperor is this guy called Phocas, who is himself a usurper, a military background, and he now faces a rebellion by Heraclius, whose base is in North Africa at this time, like around Carthage. And they have a civil war for three years, 608 to 610.

Anthony Kaldellis
That civil war that Heraclius initiates causes a diversion of Roman armies to the civil war away from the Persian front. So it’s a massive gift to the Persians. Plus, a lot of the fighting takes place in Egypt, and Egypt was a province that had up until that point not really been harmed by war. Now it is, right? So Heraclius’s forces, he’s not in Egypt, but his backers are fighting a civil war in Egypt, so that province is now, you know, ravaged in part. The Persians make tremendous gains in the east. Heraclius heads straight for Constantinople during all of this, and to make a long story short, he manages to take Constantinople, execute Phocas, and become emperor, right? But now he’s facing a problem that’s much worse than it was before he started the rebellion.

The reason why Heraclius is sort of lionized in some… Well, actually, there’s a very long tradition of doing this, which goes back to the Middle Ages. In the Western Middle Ages, Heraclius was sometimes considered, like, the first crusader.

Anthony Kaldellis
Yeah, yeah. So there’s all this medieval literature about Heraclius as being a proto-crusader type and all that for reconquering, like, Jerusalem from the Persians and restoring the True Cross and all that. So he had this kind of aura, and I think his modern admirers are basically just continuing… I mean, they might not know it, but they’re kind of continuing this very, very long tradition of treating Heraclius as this heroic holy warrior. Anyway, from my standpoint, it’s a complete wash. In other words, yes, he does beat the Persians and he gets, like, in my view, full credit for that, though he did it with, I think, the help of some Turkish allies from Central Asia. These were, I think, the major component of his success at the very end.

So the war was costly initially only for the Romans. The eastern provinces were conquered by Persia. That means Syria, Palestine, Egypt. So that’s a loss. You lose all that revenue, and then they start raiding into Asia Minor.

By the way, this is exactly what the Arabs would do, you know, just a couple decades later. They would conquer Syria, Palestine, Egypt, and they would start raiding into Asia Minor. So almost like this phase of East Roman history begins already during the Persian invasion. It’s just a kind of a prelude. It was, in fact, the Arabs that would do that for the next few centuries. So Heraclius, it takes him a very long time to get organized, in fact, something like 15 years, and it’s not entirely clear, like, what he’s doing all this time. But he ultimately manages to defeat the Persians by waging these really spectacular, weird campaigns in the East. He decides to strike into the Persian heartland, as it were. Well, first in the Caucasus region, and then he goes into Mesopotamia.

So not to try to defeat their armies that are rampaging around Asia Minor or even besieging his capital in 626. The Persians and the Avars, this people from… This nomadic warrior group that settled in roughly modern Hungary, they’re besieging Constantinople. Heraclius doesn’t even go. And he’s just kind of preparing his armies in the East, and he strikes the Persians right where it hurts, and this now begins to degrade the Persian heartland and their infrastructure because remember, both of these empires are gonna be in shambles by the time the Arabs come along, and this is what enables the Arabs to conquer them so quickly. I mean, they’ve destroyed each other in these wars.

And eventually Heraclius calls in his Turkish allies, and they go on a field trip through Mesopotamia, and this causes a coup in Persia, and Khosrow is killed.

Is there something to be said, a little bit of texture to the motivations of the different empires and the different groups involved?

What was the motivation?

So in the past, the Persian Shahs basically were interested in raiding, and they also had an interest in manpower. So all of those Mesopotamian agricultural estates won’t till themselves. So they were kind of insatiable for agricultural workforces and specialized craftsmen and people like that. So they would go into the empire and get them. But in this phase, it seems that Khosrow II is taking really to heart the idea that the Persian Empire should really extend to the Mediterranean as it did in, like, Achaemenid times, right, in, in ancient history, the empire that Alexander conquered.

So it seems that the, the Sassanians, this is this dynasty, this Iranian dynasty that’s ruling the Persian Empire, of course, they were aware of the Achaemenids, but sometimes they would have these claims to reviving the former greatness of the Iranian Empire. So, you know, bathing in the Mediterranean Sea is something that many Near Eastern monarchs, you know, they, they did this as a sign of, of success. Anyway, for the Romans, it was sheer survival, just desperate survival, ’cause they knew that this was a war that could end the Roman state.

Anthony Kaldellis
Yeah. So it’s pretty clear that initially the, the goal of Arab Muslim warfare is to unify Arabia. That is, that all Arabs should be Muslim and should be unified into this religious kind of state, whatever, that the prophet and his successors had created. Now, then they start striking out into Rome and into Iran. It’s not entirely clear, like, why. Now, there are obvious reasons. Like, I mean, we don’t– It’s not, like, a huge historical mystery why a, you know, recently formed successful army will decide to take on two very weak opponents– … who are on their doorstep. Like– … this is not, you know, complicated.

Yeah, they’re pretty effective at military– … conquest.
Yeah, they’re pretty effective at military– … conquest.
Anthony Kaldellis
Yeah. But they’re striking both empires from a direction that those empires had never prepared to defend from. Arabia was just not, “Oh, you might get some occasional raiders, but you’re never gonna get an army that’s coming out that can potentially conquer you.” So the defensive orientations are all wrong. And these two empires have gone through this massive war that has destabilized them. They’re low on manpower, low on resources. The outcome is almost kind of inevitable. I don’t think there’s a great mystery.

And the effect of that is they stripped away the richest provinces of the Roman Empire.

Yes, Egypt in particular. That means now you can’t feed Constantinople. Like we talked about the grain from Egypt, right, that came to Constantinople. You don’t have that now. And so that means that the population of Constantinople will decline dramatically over the next few decades.

Anthony Kaldellis
Very slowly. This is a painful process, and it takes them centuries, you could say. First you gotta stop the bleeding, just try to hold the line. It takes them decades to just to hold a line. Like, they get pummeled by the Arabs for decades in the seventh century until finally by the 660s, 670, they finally begin to beat them. Beat them on land and hold the line on the sea. And so we now have an investment in fleets. Eventually, you get the Greek fire, which is the flamethrowers. And when the Arabs try to take Constantinople, these attempts are defeated, like, twice, and that ensures the survival of the Roman state in some form.

Anthony Kaldellis
Well, it’s a state secret. They didn’t want this getting out, so they kept it pretty well. The fact that we’re debating it will tell you that they were pretty good at keeping secrets. So possibly through a, a pressure valve. Right? So you have this flammable compound whose preparation and components is also a state secret. So there’s specialized– There’s a corps of engineers that prepares this and deploys it. And it’s possibly through a heated pressurized container with a spigot, let’s say, that unleashes this thing through a nozzle, and it’s lit and basically spews flaming napalm on other ships, and it will continue to burn even when it’s on the water.

Anthony Kaldellis
Right? On the top. So, like, you can’t, like, swim away or anything. So it’s this very, very destructive weapon. Terrifying. They used it against Vikings too. This is much later. So once the Vikings show up- … Like, when they would raid attacked Constantinople in the 940s, then again in the 1040s- … Yeah, the Romans used Greek fire fleets to just incinerate the… And that’ll teach Vikings. Yes. If you’re in that situation, you’d rather serve under the emperors than attack them.

Yes. So it’s a, it’s like a clay container with the compound, and it has like some sort of fuse that you light on the outside and you throw it. Now, you throw it… You can throw it against people, but it’s not gonna be that effective. Maybe you burn a person, whatever. You just wasted a hand grenade for, you know, one person. It’s most effective against things like, siege engines. So you, you throw that on a wooden frame and, you know, yeah.

Yeah, eventually. Now, now remember, they’ve pulled the armies back into Asia Minor, so they’re, they’re beginning to defend and fortify Asia Minor. Now you have to find ways to pay and support and feed all of these soldiers, and this is a whole administrative—it’s a wrenching administrative readjustment. But they go through it. It takes them a long time. Eventually, they emerge with a different kind of strategic logistical system.

Anthony Kaldellis
Yes, but it happened to have a very competent man in charge. This is Leo III, and he’s an emperor who has—he’s a usurper. He’s just seized power. They knew that this massive Arab attack was coming, and so it’s quite possible that the Roman elites, you know, preferred to put someone capable in power at that moment. The city was very well prepared. I encourage people in the audience to go and read the sources that we have for that. You can find many accounts of it online. It was just very, very well done. He also had Bulgar allies.

Anthony Kaldellis
So these are the Bulgars who had just, you know, crossed the Danube just like just a few years earlier actually and settled south of the Danube, you know, where eventually, you know, Bulgaria emerged. So he had Bulgar allies, and he used the Greek fire very, very strategically. He used his own fleet. He contained the Arabs to certain places where they kind of starved and wore them down. Yeah, it’s just very well done.

I don’t see much role for good luck there. I mean, I think he had it all pretty planned out. It was all of the elements that you mentioned. And yeah, he just deployed them very, very astutely and went on to rule after that for another 20-some years, and his son continued. They formed a dynasty. We call it the Isaurian dynasty, though they were not from Isauria.

And then from that, the fascinating thing that we mentioned about religion, there was a whole stretch of time marked by intense internal religious conflicts over iconoclasm. Maybe you can clarify this, but so iconoclasm, of course, is whether sacred images, icons, should be venerated or destroyed. This had major political and theological stakes. The seemingly smallest things can have the biggest of conflicts.

Anthony Kaldellis
All right. That’s a result of this. No, that’s not what Christian churches used to be like, at least not in Constantinople. But his dynasty basically tried to limit or remove images from churches, and ultimately that policy failed. And the other side that wanted images or liked images, or let me put it differently, thought that images were not only appropriate but helpful in the context of Christian worship prevailed. And so gradually the churches began to fill up with icons, lots of icons. They’re almost like, you know, like a, a catch word for Orthodox, you know, devotion. I have icons at home. You have a little corner in the house and you have little iconography. Anyway, I mean, as a secular Orthodox person, but I… even I can’t get away from them.

You got it. I could not find… There were, like, a few emperors, and there’s some bishops and abbots and monks. Like, I don’t know, maybe 100, 200 people are, like, seriously invested in this, and they’re going at it. But these are the people who write the texts. But they never mention, for example, that, oh, you know, the, the people of Constantinople, they rose up, and they demanded icons or not icons or anything like that. Nah, never. So in my view, this is one of those controversies that’s only a few people really, really cared- … about it, and unfortunately, they’re the ones who wrote the sources.

Yeah. And not only that, when emperors changed their policy, almost everyone fell into line. They switched positions. It’s like, “No, yeah, whatever. Put the images, take the images,” like, whatever. I mean, like this isn’t, they did not see this as central. Some people did, and they got very worked up about it. Anyway, but in the end, the pro-icon position won, and their view just began to fill up the space. Like, like it literally was filling up the churches, and it still does. Yeah.

I mean, there’s a reason why you really wanna do a thousand-hour podcast on this, right? As you do, as there’s so many incredible conversations about every single emperor, every single nuanced detail of the emperors. It really is a thriving civilization. It’s a thriving empire which in it contains so many lessons for even the modern times. But anyway, you have written one of the books is Streams of Gold, Rivers of Blood: The Rise and Fall of Byzantium, 955 AD to the First Crusade. So this period has… We talked about survival and some low points. This is a period where, once again, there’s some flourishing. So by the 10th century in the Macedonian era, the empire is back. It’s wealthy, it’s culturally confident, and under emperors like Basil II who I think is in your top 10 list.

… of the whole thing. And so I set for myself the task of explaining in this book, Streams of Gold, Rivers of Blood, a very particular period that was marked by a sudden turn to conquest again after a long period of more or less defensive war. 955, a new military leadership is appointed, and the Romans go conquering again, especially in Cilicia, northern Syria, and Cyprus, and the Caucasus, and then eventually also Bulgaria. And then right afterwards, they have this generation plus period of stability and prosperity, and then they’re hit by a triple whammy. These are three new attackers. So it’s primarily the Seljuk Turks coming in from the east, some Pechenegs coming down from the north over the Danube, and the Normans in southern Italy.

Anthony Kaldellis
And under the pressure of this three-part attack, the, you know, this expansionist—what had become a more imperial state—buckles. And enters another one of these crises, just like the one we described for the seventh century. You know, survives it by the skin of its teeth. And goes on again to rebuild and become prosperous, wealthy, and powerful again, as it does throughout its history. It’s these cycles. So I just wanted to describe that iteration of that- … that process, and that’s what I do in that book.

So I think the traditional view in this perfect storm of the 11th century is that it was more to do with the internal sort of moral decay and civilian emperors neglecting the army, this internal stuff. And you make the case that it’s the external stuff, the three-prong attack, like you said, Normans in the west, the Turkic steppe people in the north, and in Central Asia, the Turks in the east. Can you describe that—the three forces—and the case that that was the main reason why it hit a low?

Well, this is also a methodological problem, right? In other words, when you’re looking at a society that suddenly faces a bunch of problems, and you could, you know, reasonably make the case for a kind of decline or a crisis, is your instinct, it’s your first instinct to suppose that there must be something wrong in the internal mechanisms of that society that, you know, led it to fail, which is what my field has done traditionally. In part because of the decline and fall model, right, of this society, we’re kind of primed to think that there was something wrong with it.

It’s a long story. Or is it reasonable to say that a society that does not seem to have any, like, particularly serious structural flaws is hit by external, you know, challenges that it couldn’t realistically have foreseen or prepared for such that, you know, it couldn’t cope with them and, as I said, buckled. And I think that’s what happened. I think that’s the main narrative. Not that there weren’t problems. There were. But no state can, I mean, medieval or ancient, can realistically survive the simultaneous attack of three very different kinds of enemies, the Normans or, like, these knights, like a new type of Western warfare that is just all about, you know, grinding the enemy to bits. But who are also terrorists. Like, they’re straight up terrorists.

Yes. The Pechenegs, who, you know, a totally different type of, you know, probably mostly nomadic horsemen. And then the Seljuk Turks who are also mostly nomadic horsemen, but who are coming in from Central Asia with vast reserves of manpower behind them. In fact, either intending to or, as it happens, effecting a demographic change in not just demographic, but ecological too, because they basically, when they move into Asia Minor, they’re transforming or terraforming agricultural land into pasturage. And they’re just backed by reserves of manpower that no other enemy of the empire has had yet.

Anthony Kaldellis
So yeah, how do you, how do you cope with these situations? I mean, they’re, it’s very, very difficult, and it’s a wonder that they survived it at all. Now, they also have internal problems, and I’m not gonna sort of try to sweep these under the rug, right? In particular, we’re seeing the end of the Macedonian dynasty. This is a dynasty that had lasted for about two centuries, and this has a kind of politically destabilizing effect. New emperors, and there are a lot of, like, childless old men in this period, are relatively insecure.

Anthony Kaldellis
They don’t have this sort of a dynastic glitz behind them, and so they’re tending to, to buy a lot of political support, like hand out these exemptions, give cash, you know, titles to anyone who will support them, and this, of course, causes a budget problem. Like, they don’t have enough money after a while. And then they have to start raising all of these armies to deal with all of these problems, and that just increases the pressure on the budget, and so there is an internal problem as well, yeah.

So you mentioned this loop of thriving and then having to survive, surviving, that happens a few times- … throughout the history of the Roman Empire. It seems that societies in general oscillate in that way. Is there something particular you could say about the oscillations, the loops that the Roman Empire goes through?

Anthony Kaldellis
Yes. Now, I don’t think this is an oscillation. At least that’s not how I think of it in my own mind. So as I explained, the crises that this em- this polity, this state, this society that it undergoes are dis- there are a discrete number of them. I can, I can tell you what they are, and we’ve, we’ve talked about most of them so far.

They don’t last very long, and they are all sudden challenges that appear from the outside. In other words, they’re exogenous shocks that they can’t really have prepared for. These shocks cause massive territorial loss, which requires adjustment, right? But they don’t last that long. In other words, the Romans almost always, at some point, figure out how to hold a line, how to consolidate their position, regroup, and put their economy and their society back on a trajectory of revival, regrowth, and eventual reconquest. Always. Every single time, except the last time, right? And for me, this poses the following kind of dilemma which I can answer.

Anthony Kaldellis
And the dilemma is, should we define the society by these brief crises of exogenous shocks, or should we define it by the centuries-long, sometimes, periods of regrowth, consolidation, and stabilization which are endogenous. Nobody came from the outside to help them rebuild. And my answer is unequivocally the latter. So I see this as a society whose internal organization primes it to stabilize and embark on steady growth. Slow and gradual, but steady. And, and that’s what I would like my field to explain more, and I’m gonna try to do so in the book I mentioned that I’m writing on, like, the longevity or the resilience of this society.

And not try to center the crises, which I see as being from the outside. Like, these aren’t… Of course, they’re part of its story, but they’re not coming from it. What’s coming from it is the stability, and I think that’s the more interesting part of this society.

Lex Fridman
Yeah, so the, you know, these peak-to-peak histories, as you can think of them, they miss the machinery in the valleys. Institutions, incentives, daily life, all of these things. The politics, the religion. You have a bunch of revisionist history ideas in your work. You’re challenging the field.

Yes. You could say that.
Yes. You could say that.
Lex Fridman
In the best possible way. So just to linger on it, what are, what are some of the things that historians miss? So this is a big one, right, that you’re speaking to, which is, like, focusing too much on specific moments versus on the broad structural underpinnings of, of an empire, of our society.

Anthony Kaldellis
Right. So what you alluded to there is a critique of what we might call short histories of Byzantium, which is a kind of genre of a book. Right? This isn’t necessarily, like, what my other revisionist ideas are about. The more important ones are things like the monarchical republic that we talked about. In other words, that there’s actually a broader spectrum of political participation. That emperors are having to look over their shoulders all the time. That there is a deeper matrix of Roman Republican thought there. Like, that’s one revisionist idea. Another one is about Roman identity, just like who are these people?

Anthony Kaldellis
And no, they are Romans, and in fact, it’s kind of an ethnic identity after a certain point. Like, those kinds of ideas. The criticism of the peak-to-peak kinds of books. So if you’re trying to condense 1,200 years into 120 pages or even, you know, even 200 pages, there’s no way to do so realistically and give a sense of the whole terrain. In other words, what these books do is they go, they jump from highlight to highlight, and these highlights are sometimes things like, you know, everything Justinian did because it’s so extravagant, to the crises.

The crises are, of course, dramatic moments that you can’t skip. And you can’t get a sense from these books as to how all of this is interconnected in the valleys, right? In the crags, down there. Like, what, what are the mechanisms that are connecting these peaks together? And that’s how I tried to write the big history, The New Roman Empire. Is to tell the story by casting light in those darker places. That is, to show how especially institutions and ideologies sort of tie, you know, people’s lives together. That is, tie people to institutions and to the broader history that surrounds them.

So that the reader can get a sense when I’m, when I’m recounting specific events or either of, you know, greatness or of a success or a failure, that they can understand roughly why these things are happening, right? Look, there’s no perfect answer. A short book will just not tell you these things. A long book, well, is a long book.

Well, in some sense, I mean, this, in this, even in this very conversation, I think we did a pretty good job of looking at the valleys, at the structure, at the institutions. And that gives you a sense of the whole underpinnings. And so it’s, it’s beautiful. It’s a beautiful way to see history, especially for societies that have lasted as long as- … as the, as the East Roman Empire has.

So zooming out and asking once again, the old—we’re getting a little close to last call at a bar, I’m gonna ask you the big question. We asked it before about the collapse of the West Roman Empire. When did the decline of the East Roman Empire begin for you? Throughout these loops, when, if you were to predict, would you be able to say where this is gonna be over? And what led to that decline and the collapse? So of course, the collapse is finally in 1453 AD.

Anthony Kaldellis
Right. That’s actually a very good question. In other words, not looking at all of the previous crises that caused loss of territory, like, you know, you lose Egypt, you lose Syria, you lose Palestine, you lose Eastern Asia Minor, you lo- right? But at what point could you say there’s no coming back from this?

Anthony Kaldellis
Right? I would say early 14th century. Somewhere between 1300 and 1350, the sources of resilience begin to dry up, and you have a number of setbacks. They lose Asia Minor to the Turks by 1300, roughly, which means that you can now no longer draw upon the two wings, as it were, the European side and the Asian side, which they could always do. They’re confined to Europe. And then you have a series of civil wars, you have the Serbian expansion and you have the Black Death, and they never recover from that. In 1300, you think of this, you look at it and you think, “That’s a tiny little Balkan state.”

Okay, it goes from Constantinople to the Adriatic in this just sort of ribbon, right, this corridor that just stretches across the Balkans. And yet, it’s not that much smaller than England and has about as much, if not more, revenue, because they’re still able to raise cash, because taxes. Right? So the emperor’s still able to pull in a lot of gold. And his territory is not, you know, completely insignificant. It’s not what, you know, the Roman Empire used to be. But I don’t think that it’s completely lost. Then they have some civil wars. Then one emper- a rebel makes a deal with the Serbs, surrenders half that territory. Okay, after that, game over. What’s surprising is it takes the Turks that long. 1453, that’s another century.

Anthony Kaldellis
Right? It didn’t need to be. It looks like they might have had it wrapped up like 50 years aft-, you know, like by 1400. But then accidental events happened. This is Timur, Tamerlane comes- … from Central Asia, trounces the Turks, breaks up their empire. So they go into a cycle of, you know, rebuilding, and so that’s why it takes another 50 years. Anyway, but I’d say by the 1340s, game over.

And so why did it collapse? What are the things in the ground, when you zoom out, the thing that ate away at the, I like this term, sources of resilience?

Anthony Kaldellis
…it’s foreign invasions, those which they could not cope with. They coped with lots of them. But, you know, it, all it takes is to lose to one, and you lose some part of your territory. And if you keep losing enough, you won’t have anything to fall back on, and that’s what happens.

Lex Fridman
So really, you know, if there’s no significant external invasions, the East Roman Empire, the fundamentals, the taxation system, the way the policies were developed, the way the politics was done, the way the representation was done, all of that, this empire could have lasted for another thousand years.

Anthony Kaldellis
Absolutely. I’m absolutely convinced of this because you never see movements to split away. That is, there’s no separatist movements, at least not on the part of any Roman provincials. There’s one separatist movement, which is Bulgaria. We mentioned Bulgaria was conquered, right, in 1018. It, there’s a couple of independentist movements, rebellions. Eventually one succeeds in 1185, so just under two centuries. So Bulgaria is the only part of this empire that actively seeks to break away and does so. But for the rest of the 1,200 years, you don’t find provincials wanting to leave this system. However much they complain about the taxes, they don’t want to leave, and they make no move to do so.

Anthony Kaldellis
You also never have a moment when the center loses its ability to tax its territories, right? You don’t have, like, widespread peasant uprisings or agricultural rebellions or these kinds of things which happens in every other one of these empires. They also never decide to partition it. The Franks partition theirs, right, like after Charlemagne. No. There are no, like, Roman warlords that try to carve out a piece of the territory for themselves and rule it independent. Nope, that doesn’t happen either. So if you’re looking at the kinds of factors that cause states to fail, fragment, you know, become ungovernable, these never happen.

… middle of one of the main corridors of empire building and new religions in the world. This is the most dangerous neighborhood, right, that you can possibly live in. So no wonder it didn’t survive. Like it would’ve been extraordinary if it had. But absent those forces, I don’t see any forces of internal decomposition that would have imperiled it, you know, significantly.

Why did the people feel represented? Yes, they… By the way, you talked about how they complain about the taxes, which is one of the signs of a healthy society, that we… It’s like complaining about the weather. The fact that you complain about the taxes actually means that you’re happy with the taxes, kind of counterintuitively, or it’s not too bad. You’re just complaining as part of the system.

Anthony Kaldellis
So you’re exactly right. So sufficient is the key word. We don’t want to idealize this, right? These aren’t, like, they’re not just dancing in the streets, holding hands and then direct… It’s so– Even when it comes to the tax system, they are complaining all the time. Of course, they’re doing so because they know that complaining gets you things.

There’s no disincentive to complaining. You might not get what you want, or you might get it, but you know, no harm will come to you. So they’re complaining all the time. They have all of these civil wars. They’re like, “Okay.” So I think I would give you a two-part answer, so really quickly, as to why this held together so well. First is that an extraordinary effort was made by the authorities to persuade their subjects that they were ruling on their behalf, and I think, for the most part, actually tended to do so. And the second is that it had a very tightly unified identity as Roman and as Orthodox. In other words, for the most, most time, they knew that they were surrounded by enemies who were not those things.

And they did not want to live under the power of non-Romans and non-Christian people. And so those two factors combined, I think, gave everybody reason to hold it together. The alternatives were worse.

Lex Fridman
Yeah. I mean, that’s a really brilliant summary, and I think we should mention that both the rhetoric and the action are important. I think you’ve articulated that rhetoric is really powerful, like stating over and over and over- … that you represent the people, that you’re acting on behalf of the people and doing the action. But it’s not enough to actually do the action. You would think that’s all Machiavelli says, that’s the only thing that matters. But no.

I’ll give you an example. As an academic administrator, right? I mean, I was chair of department for years and years. There’s a difference between a dean who says, “Sorry, bad budget situation. We’re just gonna have to cut your programs,” on the one hand, and a dean who says, “I am fully on board with what you’re trying to accomplish with these programs. I am a defender of the humanities. Unfortunately, we have this budget situation, and we’re gonna have to cut some of the programs. But I assure you, the moment I’m in this with you together- … the moment we find the funds, we will restore them.” Those two just rhetorical strategies, they’re aiming at the same practical outcome, will produce very different levels of compliance- … right, and consensus.

And I should say that there’s subtlety there. The best rhetoric in that context, and maybe in the East Roman Empire, is you also have to believe it.

Yes. It has to be credible. You can’t just say it and then not do it.
Lex Fridman
But one of the things I’ve learned about humans, just having doing this little podcast, is that… People could– Like, the best way to say a thing, a powerful thing, is to really believe it. And so, like, this is clearly one of the things that made the Roman Empire work, is doing the action is the best way to make the rhetoric powerful and effective.

Anthony Kaldellis
Yeah. This is sort of what Aristotle says about tyrants. In The Politics, Aristotle’s giving essentially advice to tyrants on how to protect themselves because tyrants are usually hated and are killed in coups, right? And he says, “Well, how are– You know, essentially, how do you manage to secure yourself when you’re a tyrant?” Well, you know, you can start by maybe, you know, obeying the laws or making sure that your subjects obey the laws and, you know, maybe work for the interests of yourself. Essentially, he’s telling them to kind of become benevolent kings. And the best way to persuade your subjects that you’re legitimate benevolent kings is to be that.

Lessons from history
Lex Fridman
So what, from all of this, from this 2,200-year history of the Roman Empire, what lessons can we draw for modern times? Now we’re sitting in America, this young empire. I know we’re not calling it an empire, but, you know.

Anthony Kaldellis
Lots of people are calling it an empire. I thought it was sort of taboo. Yeah, in the 20th century, it was like, “Is America an empire now?” But like, I think since the Iraq War, like since 2003, I’ve seen at least very casual uses of America and empire in the same sentence without any kind of hand-wringing.

I will say that, just drawing on what we were talking about a moment ago, that investing in institutions that work for the majority of your subjects, even if indirectly—like they have to pay a cost for them, but you have to explain to them why they’re paying that cost—is to the benefit of the ruling classes as well. Because you’re, you’re– ideally, you’re thinking about long-term success and not just your own short-term, you know, gain. And I think that’s what this society tends to do well. You know, the Romans generally, you know how they built roads for the centuries and the millennia. They built institutions too. You know, one of the institutions they built was, like, the Christian Church. Like, they build things to last.

And so that’s to the Machiavelli’s point that we want to maybe narrow that gap for a successful empire, for a successful nation. The rhetoric has to match the action.

So in the context of the society I study, let’s say the army is the single largest expense, is doing pretty much what the emperors say that it’s doing, which is protecting its subjects. That’s actually what it’s doing most of the time. Not all the time. So, for example, emperors will sometimes take the armies out on a raid or an expedition, you know, crack some skulls, gather some plunder, come back, and this is done to glorify the emperor. Like, yeah. Yeah, yeah, this does happen. But for the most part, they’re doing that, not much else.

Yeah. I don’t think most of the world even believes, you know, what American leaders say their goals are, especially when it comes to, like, war. Like spreading democracy? No, really? I remember when they were trying to convince me, us, that the invasion of Afghanistan was a feminist war.

I think there’s a lot, a lot of wake-up calls about the war in Afghanistan and Iraq, where people realized that there is that gap between the rhetoric and the action. And I mean, that’s how, because of a lot of people waking up to that, they create pressure on the government to close that gap. And that’s- … how we kind of navigate this- … complicated world, but it’s a costly one. I mean, these, these were extremely costly wars- … on every front, on every measure.

Yep, but the same lesson was learned in, like, the Vietnam War, and that was such a disaster that essentially they had to switch to– to abandon the conscript army, switch to a professional army. And, like, it took them so long to be able to, like, wage, you know, these empire wars again because of the sheer damage that the Vietnam War did to the credibility of the military leadership in the country, right? This never happens in, like, this doesn’t happen in, in Constantinople. I can lose a– You can be criticized for losing a war. That’s, that’s one thing, right?

There’s no right answer, and by the way, I don’t wanna be ruled by kings or monarchs or emperors either. So it’s like I wouldn’t necessarily support that.

So you, you said that, you know, the Roman Empire, maybe ancient Greece, maybe the societies before that, and now societies after that, the society we live in are very different. And so applying the lessons of history, you have to be careful doing so. But are there things that are the same with us humans? So of everything you’ve studied across hundreds of years and centuries, are there aspects of human nature that kind of persist?

It was very common to find colleagues who did not believe that there was such a thing as, let’s say, human nature. In other words, that, let’s say, the parameters of human psychology are, you know, yes, there’s considerable variation, but they’re within a certain set of norms. Like it’s not— we’re, we’re not gonna behave like different species. And they did not believe that there was such a thing. In other words, that all of human history is essentially a series of incommensurate slices of difference, right? That you just couldn’t go from one to the next.

Now, culture then comes in and, you know, tweaks things in all kinds of weird ways, and that’s, as a historian, what I like to study.

And I would say we’re probably in the third. I think there’ve only been three phases. The first one being sort of hunter-gatherer period, which- … that lasted for the majority of human history so far. Right? Then there’s the agricultural revolution, basically.

It’s actually consciousness, and consciousness is the thing that is very difficult to engineer. And so that’s the common thing from the hunter-gatherers to before the Industrial Revolution and after, is we’re still the same. We still feel like something to be alive, and that’s maybe an important component of what makes us fall in love with each other or fear each other or suffer and all the full range of the human condition, the human experience.

I think they’re solvable problems to a certain degree. Like, if we can rein in some elites, a lot of these problems can be fixed, and that’s not like a super difficult… I mean, it’s difficult, but it’s not, like, impossible.

Look, so I, I grew up during the Cold War. Let’s just take the ’80s, for example. And in the ’80s, like, there was a pervasive sense that nuclear war could happen at any time and just annihilate everything, and we lived under that. If you look at the popular culture of the ’80s, it’s, like, all, like, upbeat and cheerful and naive and- … like, there was just no correlation. And then you move into the ’90s, and the Cold War is over, and everyone’s all depressed. The music gets all, like, whiny, and it’s like, “What happened?” There’s just no correlation. Anyway, I just think that the, the, it’s a pervasive sense of hopelessness or, you know-

I think this period of human history will be– ’cause we’ve talked about the ups and downs of the Roman Empire. I think unquestionably, this period in history, the 20th, the, the late 20th century and the 21st century will be seen as the flourishing of humans. So if we actually just wake up- … it’s like what everything around us, by most measures of human flourishing- … we’re doing pretty well.

The amount of, like, sheer misery is probably objectively decreasing every year. Now, you know, we’re also creating problems, yes, that will cause misery down the road. Yes. But overall, I don’t see a reason to despair and not have hope.

Unifying the laws of nature
Lex Fridman
In describing the search for theory of everything in physics, you describe the history of physics can be told effectively as a kind of history of unifications. There’s this centuries-long quest to show that these distinct phenomena are actually linked by some unified underlying principles. Even starting with Newton, that you can think of the effort of physics as one is trying to unify- … the laws of nature. So I was wondering if we could talk through the history of unification-

Don Lincoln
There are, of course, lots of different ways to do physics, but the way that I would say that particle physicists, cosmologists do is they are trying to really find basically the underlying principles that govern the laws of nature. If we go back, say, to the, I don’t know, 1650s or so, you’re the most brilliant person around, and you’ve noticed two things. One you’ve noticed is that when you trip, you fall. That is the nature of gravity that we all experience day to day. But then there’s sort of astronomy, where you look out at the heavens and you see the stars march across the sky. You see the planets move through the stars. And there, that seems to have absolutely nothing to do with what happens when you drop your sandwich and the dog grabs it from you. So-

Don Lincoln
… the brilliant thing was when Newton looked at that and he thought about, maybe the moon is falling, but it’s missing the Earth. So what we had is that in maybe 1650, you had what we might call the laws of celestial gravity, the gravity that governs the heavens, and terrestrial gravity, the gravity that is here on Earth. Now, we don’t think of it that way anymore. We think of it as just gravity. But at that time, that wasn’t at all obvious. And in fact, if you look in the books, Newton’s theory is Newton’s law of universal gravity. The universal is there, and the reason is, is because he realized these two things that seemed to have nothing to do with one another were indeed one and the same. I mean, this is absolutely brilliant.

Don Lincoln
I mean, Newton is arguably one of the most brilliant humans of which I’m ever aware. But at any rate, it is the first sort of easily to describe unification of physics that you can state in a way that sort of makes sense to modern- … Humans. I mean, you can go back farther than that, where people are talking about chemistry, the nature of atoms. You go back to Democritus, who was wrong about very many things, but the idea that there was a smallest particulate form of matter is right. So it’s kind of funny. You talk– You, you read the chemistry books, and they say that the idea of atoms goes back to Democritus, and, you know, he, his idea was that, like there was a smallest atom of oil, which was smooth, and it was smooth, of course, because, well, oil is smooth.

There was a smallest atom of vinegar because vinegar is tart and it pricks your tongue-

… so therefore, atoms were little sharp, pointy things. And so he was wrong about a lot, but he was right about the idea that there was a small particle, and, and we now know a very– we have a very different concept than he did. So you can go back farther than that. But getting the unification, there are more examples. For instance, if you go back to, say, 1830 or so, scientists were trying to understand electricity, for instance. And there was a lot going on. People really understood things. But at the time, you would have two phenomena that are familiar to us now. One is a magnet, which, you know, at the time, mostly magnets were, were simply little pieces of iron that had been magnetized and they could stick to steel.

And then you had electricity, which was at the time they were generating little sparks that they could play and have fun with, or more broadly, a lightning bolt blazing across the sky. And so when you think about this, that lightning bolt and that little magnet seem to be really unrelated.

Don Lincoln
But over the 1800s, a number of scientists were exploring little aspects of it. What happens when you run electricity through a wire? It seems to make a magnetic field. You know, they– There was a whole bunch of experiments and there were a lot of names. But in about the 1860s or so, James Clerk Maxwell took all of those ideas that had been percolating around for the previous 50 years and wrote his laws of electromagnetism, and they’re really fascinating. If you look at the laws of electromagnetism, they are– they’re differential equations or integral equations. But basically, what they say is on one side, you have a bunch of terms that have electricity in them, and then you have equals on the other side, a magnetism thing.

Don Lincoln
So forgetting all of the mathematical symbols, you have electricity side equals a magnetism side. Electricity equals magnetism. And that is a staggering concept, the fact that these two things, a lightning bolt and the magnet that holds your kids’ art to the refrigerator, are one and the same. And this was another case where electricity and magnetism became unified into electromagnetism. So now we have two examples: one, gravity being unified, terrestrial and celestial gravity, and then electricity and magnetism. So I’ll tell you about some more in a moment, but one thing that’s kind of important because the goal is, of course, to unify everything.

That if I could do what I want to do, I would have some unified theory that would explain all the behavior of all energy, matter, space, and time, which is a grand goal.

Lex Fridman
And we should say that maybe one of the goals of science more broadly, outside of physics even, is to construct models that can generalize the world. So if you look at Darwinian evolution- … that was a very beautiful theory that captures another layer of reality of, like, how this particular thing that we see here on Earth happens. So when we talk about theory of everything in physics, that’s capturing a different layer of abstraction about the functioning of the universe.

Don Lincoln
Right. The whole Darwinian evolution, the fact that our genetics has significant overlap with the genetics of a banana is, is pretty staggering, is astonishing- that that works. So that is amazing. But for at least the class of scientists that I am, what we think of is, well, sure, biology is interesting and all, but when you get right down to it, it’s caused– whatever happens in biology is caused by the movement of molecules. And then you say, “Well, that’s great and all, but molecules, they do what they do because they’re made of atoms.”

Don Lincoln
And then the next step is, well, atoms, that’s great, but atoms work the way they do because of the nucleus and the electrons, and then the nucleus is protons and neutrons. And so there are those of us, myself included, who want to dig down to the very, very bottom and find out what is the smallest building block of nature from which all of these other far more complex and interesting and abstract things are. But what is at the very, very bottom? And also, that’s great, but if you know what the smallest building blocks are, that doesn’t tell you the story. It’s like having a whole bunch of Legos, but not knowing how to put them together. You also need to know how they interact, how they work, and so that’s why we study forces.

Don Lincoln
So there are the various subatomic forces of which we’re familiar and for instance, electricity and magnetism are components of electromagnetism, which then governs the behavior of things like– This is amazing. Electromagnetism explains, of course, electricity, magnetism, but it explains how light works. It explains how much of chemistry works. So electromagnetism, 1860 or ’70, the wonderful thing about that is if you take Maxwell’s equations and you apply a little bit of calculus, it’s very easy to see that the laws of electricity and the laws of magnetism combined together make what’s called a wave equation, which that shows that these electric and magnetic fields oscillate.

Don Lincoln
They vary, and if you have something that’s varied, that’s a wave, and the wave then moves. And if you do the math, you find out that the speed at which these waves move is the speed of light. And so people said, “Wow, the speed of light comes out of those equations.” And that had to be, I think, very persuasive. And of course, electromagnetism also plays a really significant role in chemistry because after all, atoms are held together by electromagnetic forces. There’s more to how atoms work. There is all the quantum mechanics stuff. But if you did not have electromagnetism, or if electromagnetism was very different, then atoms would be very different. So it plays a very big role in holding us together.

Don Lincoln
So it’s a staggering advance in science to have a good behavior on that. And of course, being able to tame electromagnetism is why people can hear you when you do your podcast because through the miracles of the internet just– or just electricity running the computers. I mean, this is a case, if I can get on a small soapbox, where people back then said, “Well, why are you messing around with magnets and sparks?” And who cares? Well, that very fundamental digging into the laws of nature has spinoffs, and it has spinoffs– one of the big spinoffs is our entire technological society.

Without being able to govern electricity, we’d still be farmers and shoemakers in cities. We certainly would not have everything that we do, so off my soapbox. But it’s really a lovely thing to show how this, this digging into deep, fundamental, not understood, mysterious things can, a hundred or two hundred years later, transform the world.

And the type of science I do now, people often ask, “Well, what good is knowing about how the inside of atoms work, how the inside of quarks work?” And I don’t know the answer to that but just being a little more pragmatic, if I go back, say, a hundred years, where people were trying to understand how the protons and neutrons inside atoms held together, how they split, how they– how you could combine them and so forth, this has led to nuclear power. Now, whatever you think about nuclear power, and some people like it and some people don’t, but it is powerful. It will generate energy for humanity, and it may be that is the path that we take as we move away from digging fossil fuels out of the ground. Humanity is going to need power no matter what.

Don Lincoln
Nobody is going to go back to the way things were in the 1700s. And one enormous source of energy that is there for us to take if we so choose is the modification of the nucleus of atoms. Seemed to have absolutely nothing to do with anything, and yet it provides humanity with an opportunity, which of course requires that we think carefully of how we do that and, and if we want to, but it gives us something that we didn’t have before.

Lex Fridman
Yeah, it’s very clear that nuclear fusion and nuclear fission will unlock huge amount of energy that’s required for a civilization to flourish, but that’s almost like near term. Longer term, you can think about things like we’ll talk about dark energy crisis- … and antimatter. Maybe if you figure out some of the mysteries around antimatter, that too would lead to energy sources, how to produce energy. That too might lead to counterintuitive propulsion systems-

… for us humans to travel through the universe. Now, right now it seems far-fetched, too expensive, too complicated, too difficult, but breakthroughs in the fundamentals theoretical physics might lead us to unlock some incredible energy sources, incredible technologies that will allow humans to explore the universe. And of course, we should also mention that as always with technology, it’s a double-edged sword. It will most likely lead to the development of more dangerous weapons or- … other sources of harm. And then we as a civilization kinda have to walk that line and hope we figure out how to do more good than bad with the technologies we build.

Don Lincoln
Right. But we have to really remember, while people worry about nuclear weapons, which are admittedly very dangerous, and even nuclear power, which has waste that has to be dealt with, what science is doing is working out, finding power that nature has presented to us. This is not new. Fire is like that too. Fire can burn down your house or it can cook your steak. Power is like that, and that’s just something that we have to understand as humanity, and that’s why this needs to be a– you know, when we talk about science, it has to be a broad conversation by all of society because what scientists can do is figure out how the world works. Society has to figure out how we wish to apply that or not apply that.
Right. But we have to really remember, while people worry about nuclear weapons, which are admittedly very dangerous, and even nuclear power, which has waste that has to be dealt with, what science is doing is working out, finding power that nature has presented to us. This is not new. Fire is like that too. Fire can burn down your house or it can cook your steak.

So that means that that’s the thing that makes us human in part is looking at a thing and saying, “How does this work?” And then together a bunch of apes get together, like, poke the thing, kinda shake the thing. And then over time you have rockets going all into space. You build roads and bridges. You build the internet. Anyway, so we talked about Newton, we talked about Maxwell. That takes us into 20th century in terms of unification. There’s a guy named Einstein- … on whom you wrote a book, who did- … quite a lot of progress on the effort of unification.

Einstein, special relativity, and general relativity
Don Lincoln
Sure. So Einstein, he’s a pretty amazing guy. In 1905, he had his miracle year where he wrote multiple papers. The one that most people know about is special relativity, where he showed something that makes no sense to anybody who’s not really dug into it very hard, and that is that two people experience time differently. Time, you know, is a fascinating thing. We don’t really understand what time is, which is weird. You’d think that that’d be something we’d understand very well, but we really don’t. We know a lot about it, but really understanding it, not so much. But Newton thought that time was just universal for everyone, so my time, your time, some person’s time on Mars or on Alpha Centauri, everybody experienced time the same.

What Einstein showed was that that wasn’t the case, that different people moving at different speeds with respect to one another experience time differently, which is absolutely a mind-blowing concept. Now, most people think that Einstein then said, well, he invented spacetime, that space and time are the same thing, and he was behind that. But that actual insight came from one of his teachers, a guy by the name of Minkowski, who looked at Einstein’s equations. Minkowski was a little bit more mathematically inclined than Einstein, and he saw that if you look at the equations, you have basically one person’s space and time equals some numbers times this person’s space and time. And so that’s kind of a staggering thing.

So that is where Einstein and Minkowski really did this unbelievable concept that space and time are actually pretty much the same thing. That runs afoul of our understanding of how the world works because time just moves, it’s continuous. We know what it is at a visceral level and an experiential level. We might not understand it at a formal level, but we know what time is. It’s what keeps, makes today today and not yesterday or tomorrow. Space is a little different. You can walk somewhere, you can walk back, you can move around. You have more freedom to move in space than you have to move in time. You can always move forward in time. It’s just moving backwards that turns out to be a little more difficult.

But yeah, Einstein’s understanding that that is the case, it caused everybody to think about the world very, very differently, and that was in 1908 when Minkowski really laid it out in a strict spacetime.

And that also led to the work on special relativity, led to the speed limit, the speed of light.
And that also led to the work on special relativity, led to the speed limit, the speed of light.
Don Lincoln
Well, it was a premise. He had two premises. One was that the laws of nature are the same for everybody, so if you’re moving at some speed, or if I’m moving at some speed, I can say I’m not moving and saying you’re moving at some speed. That’s not controversial. That is what we call Galilean relativity. It’s from hundreds of years ago. But what Einstein said that was controversial was that everybody measures that the speed of light is the same. Irrespective of how we’re moving with respect to each other, you’ll measure the speed of light to be a number, I’ll measure the speed of light to a number, and that’s very, very different from what Newton would’ve said or Galileo or any of the old guys.

Don Lincoln
And it was taking those two things together that caused all of the weirdnesses of special relativity. Now, you could then very easily say, well, that second premise that everybody measures the speed of light to the same is just dumb, and y- it– that, you know, you could test that. So that’s where testing relativity comes in. And Einstein’s equations, which include those two assumptions, it predicts the behavior of everything perfectly well. Now we’ve actually measured done experiments where we can say that the speed of light is the same for everybody. That’s not how that’s been in the beginning. It was really that assumption leads to predictions. The predictions are true, so the assumption is true.

Now, there is a– for, for those people, for your viewers who wanna say, “Well, how do you measure that the speed of light is the same for everyone?” The particle physicists do this, and the way you do this is the following: There are some subatomic particles that when they decay, they emit light. That’s their decay product. And so you collide two things together so you know when the particle was created, then you have surround your collision point by a detector, and you measure how long it takes for light to get to your detector, and by God, it’s the speed of light, which it should be. However, sometimes in these collisions, some of these subatomic particles you make are coming out at very high speed.

Don Lincoln
They might be coming out at ninety-five or ninety-seven or very large fraction of the speed of light, and then they decay into photons. And so you measure how long it takes for the photon to get to your detector, and it says it’s– light travels at the speed of light. Now, if it were that if Einstein’s conjecture was incorrect, you’d have a particle coming out at near the speed of light, it would be decaying into a particle traveling at the speed of light, then that particle should have traveled at, say, two times the speed of light or something like that, so it should have taken half as much time to get to the detector, but it doesn’t.

Don Lincoln
So this is a hard, serious measurement that shows that something, you know, we, we can measure the speed at which light comes out of this stationary created particle, and it’s the speed of light. Then we can measure what the speed is of it coming out of something that’s moving, and it’s still the speed of light. So that is an actual measurement, but that is not something that was possible in Einstein’s day- … but it is now.

Just to take a small tangent, how weird is it in the full ranking of weirdness that is physics, how weird is it that there’s that speed limit of the speed of light?

Don Lincoln
Well, I have to tell you, when I first encountered this, it’s pretty freaking weird. It, like, pegs the weird meter. But as you become more familiar with it, as you become more, more comfortable with the idea, the thing to remember is the speed of light; it’s the speed of light through spacetime. Once you embrace that, that makes a whole ton of sense. It all of a sudden makes everything fall much more into place. I think that there is an ultimate speed isn’t that shocking. It just simply says that it’s a property of space in the same way that there is, you know, space can transmit a certain strength electric field. It can support certain things.

Whatever space is, and we don’t know what space is, but whatever it is, it has the capability of transmitting these things at that one speed through space or time, and everything else comes from our insisting that we keep space and time different. That’s, that’s how I view it, and at least for me, once I accepted that, it all became very comfortable.

So the nature of my question actually here- … that will apply over and over is trying to empathize, trying to put ourselves in the shoes of the people before space and time are unified- … into spacetime and really experience and think through how difficult of a leap is that.

The reason I sort of say that is we are now in the modern day in the twenty-first century, and of course, we’re gonna have to make leaps like that in our future. So what are the unifications we’re not seeing in front of our eyes? So for example, there’s so many examples through your work, through your lectures of Paul Dirac taking antimatter seriously. Looking at what the math shows and saying, “I really think this thing exists.” I mean, it just sounds insane.

And so I think this is a good warm-up. The space-time unification- … is a good warm-up as we march through the twentieth century ’cause it gets, in my view at least, weirder and weirder, even with Einstein himself.

Well, let me give you an even more basic example, sodium and chloride. Sodium is an explosive metal. You put it in water and it’s kind of neat. You put it in water, and it just, it doesn’t quite explode, but it gets hot, and it pops around. Chlorine, it’s a gas. It’s going to kill you. So these two things are deadly. They’re awful. And yet when you mix them, you put it on your food at night. It’s salt, right? And so this is a case where this whole, A, unification and B, this deeper understanding, in this case of chemistry, of how two things that are dangerous can be brought together and turned into something not only innocuous, but necessary for human life. And so this is not unusual, what you’re describing.

I mean, when you think about it, forget about everything else, just the fact that, you know, we tell little kids that the world is made of atoms. Now, that’s crazy. Most people have never seen atoms, and yet nobody really doubts it anymore. And I think it’s just a case of familiarity, and then the culture slowly accepts it, and it’s then, it’s real even without the evidence. In fact, one of the courses you described there how we know what we know, I think that’s a valid question. How do we know there are atoms? And of course, there are ways we do.

And by the way, on that front, I would love to go through how we know the building blocks in the universe as we march towards quarks. That, in the course that you mentioned, is one of the most fascinating things of this philosophy of atoms being around for a very long time. Then you concretize and you actually can prove or have strong observations that indicate that there is atoms, and then there is a nucleus, there is electrons, there is photons, there is quarks, and I mean, it gets weirder and weirder, and now we’re facing the mystery is there’s building blocks even smaller than that.

But anyway, Einstein, turns out, didn’t just do special relativity. By the way, I really think he deserves three Nobel Prizes. He got it for photoelectric effect. The fact that he didn’t get it for general relativity is a crime against humanity. I don’t understand. Obviously should have gotten it for general relativity and special relativity. I mean, I think special relativity is separate from general relativity in terms as far as Nobel Prizes go. So general relativity is another unification.

Yes, that’s right. What Einstein realized was that if you were in a rocket ship and the rocket ship was a very quiet rocket ship and it was accelerating, it would feel like you were experiencing gravity. And so as you say, it’s one of his happiest moments when he realized that acceleration and gravity feel very much the same. What I’m impressed by is that idea, which is already a pretty neat idea, somehow led him to take his space-time idea, take this acceleration gravity idea, and realize that he could describe gravity as the bending of space-time. Space-time being constant like east, west, north, south, that’s already hard enough. But now he’s saying, “Well, you know, take your map and crinkle it and bend it,” and so forth, and that’s gravity. That is a staggering, mind-blowing idea.

I guess, I wonder if you can comment on what do you think is the idea generation process that leads to that. So probably an Einstein case has to start with what if gravity is itself space-time geometry? You have to have a thought like that, right?

Yes, I think so. There’s a lot about science. There’s, of course, knowing what went before. There is knowing the mathematics that allows you to figure out the implications of your theory. There is the discipline to argue with yourself and other people because most ideas are wrong. But then there’s what you just described, that intuitive spark, and that is something that is very, very difficult to create. There’s a reason that we venerate these people, is because it is an unusual feature, and most people only have that aha moment once in their lifetime, if they have it at all.

And then there’s a tricky business because I’m sure you do, and I get a lot of letters from creative thinkers who don’t have all of the history and the mathematical discipline and the self-critique that’s necessary. And so they come up with these ideas, and often it’s easy to see where they just don’t play out. So in order to be that person who changes the way we see the world, ideas themselves are not enough. These creative ideas, that’s not enough. You need it with the discipline and the critique, and it’s that amalgam of those things that you know, make you a genius that history remembers.

But it’s hard to know. In a field of people you might be tempted to call crazy, there could be geniuses there, and it’s hard to know which is which. We should mention that Einstein himself couldn’t see the genius in quantum mechanics initially, couldn’t see the correctness, I should say. So he could see the insanity of gravity bending space-time, but quantum mechanics was too weird for Einstein.

And if you’re able to critique an idea, you might kill it. And that is—it’s always depressing when I have this brilliant idea and it gets killed, but it’s better to be killed than to keep it around and waste time on it. And so he was, in that case, not generating the aha. What he was saying is, “All right, let’s take your aha. Let’s see it’s right. What does it mean? It means this.” That allows people to go test it, and so he was contributing very crucially to that other part of scientific advancement, which is not just the aha moment, but the beat it to death, test it-

So, you know, we’re sort of jumping forward here now to the 1930s or thereabout. And at, by that time, people had realized that there are four distinct forces that do not seem to be connected. One is gravity, two is electromagnetism, and those are things people are relatively familiar with. But there are two other forces that only have any real importance inside the nucleus of atoms, which is why most people have no experience with them. One is the strong nuclear force, which holds the nucleus of the atoms together, and the other one is what we call the weak nuclear force, which is responsible for some types of, of radioactivity. And since most people don’t play around with nuclei, and most people don’t play around with radioactivity, they don’t know what that is.

But by the ’30s, scientists had done enough experiments, done enough theorizing to, to say that there were these four forces, and that was already a triumph. I mean, we, in our goal for a theory of everything, we’d like to think that there is one force, which is what we’re talking about, the unification. Maybe these four forces are, are just different ways of looking at a single underlying force. But in the ’30s, that’s where we were. There were the four forces. So we move ahead, and in the late ’50s and early ’60s, some people were thinking that maybe the weak nuclear force and electromagnetism actually were the same. So they were working on trying to bring together these two forces to show that they’re connected. And it came true.

They were able to show that electricity and magnetism were actually two different facets of a single force that we now call the electroweak force. Now, the story that you’re told in articles about this, about what people have called the Higgs boson or the God particle, the story is very, very simplified because in 1964, there were three groups with six individuals who came up with important papers talking about what’s called the Higgs field. And I’ll get back to what that is in a minute, but the Higgs field is important. But it wasn’t until 1967, so three years later, that Steven Weinberg and some others actually unified electromagnetism and the weak force.

Don Lincoln
Right, and that was in ’67, all right? Everybody talks about this thing happening in ’64, but it really wasn’t. It happened over quite a few years actually. But all right, so now let’s— what you said is true. So Weinberg, Glashow, and Salam showed that electromagnetism and the weak force at high energies were the same. There was a problem, however, and the problem is that electromagnetism has an infinite range and we know that because we can see stars that are millions of light-years away. I mean, that shows you that the range of that force is essentially infinite. The weak force, however, basically becomes nonexistent on distances much smaller than the size of a proton.

So that, you know, to say, “Oh, they’re the same,” and yet one can reach across the universe and one can’t reach out of an atom, well, that’s just dumb. I mean, the obvious thought here is, well, we just proved that that whole idea is stupid, so throw it away. Ridiculous. And that is where these ideas from 1964 came in and saved the day. So how can it be true that the electroweak force is real and electromagnetism and the weak force act so differently?

The way that could happen is if these forces were transmitted by a particle moving from one subatomic particle to the other. In the case of electromagnetism, it’s the photon. In the case of the weak force, we call them now the W and Z particles. So the idea is that Higgs and his colleagues came up with is saying, “All right, electroweak force is real. The way we make it so that there is now an electromagnetic force and a weak force is the force-carrying particle of electromagnetism has no mass. The force-carrying particle of the weak force has a mass.” And so what was done is a field was postulated that there was this additional field that was kind of distinct from this electroweak field, and we call it the Higgs field. And the Higgs field permeates all of space.

And here’s the kicker, some particles interact with the field, and some particles don’t interact with the field. The ones that interact with the field get mass, and the ones that don’t interact with the field don’t have mass. And so that’s the idea, is that the Higgs field gives the weak force particles mass. However, the photon laughs at the Higgs field, doesn’t see it, and it has no mass.

And I should say here, going to Perplexity, the big-picture view, the Higgs field is the quantum field that fills all of space and gives many elementary particles, just as you’re saying, their mass through their interaction with it. The Higgs boson is the particle associated with ripples or excitations of this field. In modern particle physics, every type of particle corresponds to a field that exists everywhere. The Higgs field is one such scalar field, meaning at each point in space, it has a single numerical value rather than a direction. The Higgs field differs from most other fields because even in empty space—empty in quotes, by the way, empty space—its average value is not zero. This non-zero vacuum value is what enables it to endow particles with mass.

All right, so right in front of us, there is a gravitational field. Now- … you can’t see it, but right there. Right there. Check it out. If I were to take something, a pen or whatever, and put it there, it feels a force, and it falls. Very insightful, I know. So we have the gravity field, and we have the pen that has a mass, and the mass and the gravity field interact, and it drops. Now— … if we had another-

This thing has mass, and we drop it. How remarkable. It falls. But when we step back and think about what really happens, it’s the mass of this thing and the interaction with this invisible field we see here. That’s what gives this weight. Now, I have this particle here that you can’t see, but it’s there. It has no mass. And I leave it there. Well, since it has no mass, it doesn’t feel gravity. It’s still floating there.

And that is really all the Higgs field is. Some particles have effectively what you could call the Higgs charge that interacts and sees the field, and other particles don’t. And that is really what you read just basically means. Now, it’s kinda neat because in the ordinary day, there is a Higgs field right there, and the Higgs field is not zero, just like gravity is not zero, and things will get mass. But at super high energies, the Higgs field, the strength of the Higgs field goes to zero. So whether things have mass or whether they have a Higgs charge or not, they have no charge– or they have the Higgs charge, Higgs field zero, they don’t interact. It has no mass.

So that’s kind of what Weinberg and Salam and Glashow said, is at very high energies, the Higgs field is zero. Since the Higgs field is zero, the weak force particles don’t feel mass, and therefore, they can travel at the speed of light, just like the photon does, and everything’s happy.

It is when the universe cooled down. After the Big Bang, it was very hot, very high energy. Nothing had mass. The universe cooled, and at a certain temperature, what happened is the Higgs field turned on. And at the moment it turned on, it gave mass to the weak force particles, did not give mass to the photon. So that’s what we call electroweak symmetry breaking; so it’s a mouthful. But all it says is there was a moment in time early in the history of the universe at 10 to the minus 12 seconds after the Big Bang, the Higgs field turned on and particles got mass. So that’s the whole idea. So this is another really neat thing. So the electroweak symmetry theory doesn’t need Higgs because that only really applies at very, very high energies.

But in order to make it work at low energies, you need to fix the theory, and you need to fix the theory by effectively putting a Band-Aid on the theory. Higgs theory is just a Band-Aid on top of electroweak symmetry theory, and that is the Band-Aid that fixes it because it gives mass to particles at low energy.

Okay, excellent. So we have never seen the Higgs field. Higgs field is a hypothetical theoretical thing. But that is true of most of our fields. We’ve never seen the electromagnetic field. We’ve never seen the gravity field. We’ve seen the effect of the field. And so all of these theories are now what we call quantum field theories, and that– the whole idea of quantum fields is if you have a quantum field, that field can vibrate like a drumhead. And so it doesn’t vibrate just exactly like a drumhead, but it vibrates locally. So you can have specific localized vibrations, and those specific localized vibrations are the particles. In the electromagnetic field, the vibration is the photon. In the Higgs field, the vibration is the Higgs boson.

How particle colliders work
Don Lincoln
And so what we can do is not see the field, but we can actually excite the field, make it vibrate, and detect the vibrations. So the Higgs boson idea was predicted in sixty-four. It became useful in sixty-seven, and then scientists started looking for it. So in the early 2000s, people were starting to think that we had built particle accelerators powerful enough to actually to be able to create these vibrations and detect them. So the accelerator that was working at the time was a large particle accelerator outside Chicago at Fermilab called the Tevatron.

And we were colliding protons and antimatter protons at near the speed of light at very high energy, and that was the accelerator at which the top quark was discovered in ninety-five. But we had upgraded our apparatus. We had ten times the number of collisions per second. We had slightly more energy, and we were banging the protons and the antimatter protons together, hoping that we would actually find the Higgs boson.

Can you actually back up a little bit and look at the bigger picture? So Fermilab has this legendary accelerator that there’s also a personal story with you connected to it because, I mean, there’s a million questions I wanna ask you, and we’ll ask you about some aspects of that. So this idea of an accelerator, the design and the physics of an accelerator, how is that productive for understanding and discovering different aspects of particle physics?

Well, I’m so glad you asked . I mean, this is fascinating. All right. Everybody has heard Einstein’s equation E equals MC squared. Nobody knows what it means. Maybe they heard that energy equals mass and mass equals energy. I don’t know, you know. But they’ve heard the equation, the most famous equation in all of science. But buried inside that equation is a really thoroughly fascinating concept: that energy and matter are equivalent, and you can, in fact, convert movement energy into mass. And so this is something that we’ve known for a long time. This was predicted back in basically 1928, so a long time ago, actually almost a hundred years ago. And it is not in the slightest bit controversial. We can do this all the time.

So the simplest thing is to take two particles that have no structure, so, you know, the closest thing you can have to BBs that are just true mathematical BBs. If you smash those two things together, it’s coming in with a huge amount of energy from one direction, a huge amount of energy from the other direction. The directions cancel, so the net momentum, the net energy of this has no motion. So you have these two things coming in with a, you know, exactly balanced energy, and if they collide, they could stop. Well, that energy has to go somewhere, and that energy can literally create mass, create particles. Now, there are special rules about what happens. If you have two things coming together and it creates a particle, it has to create an antimatter particle to balance it.

That’s just kind of the rules of the laws of nature. Why is that the case? Well, we have some ideas, but in many respects, the answer is because those are the laws of the universe, and that’s the things that we try to understand.

But this is absolutely true. So what particle accelerators do, among other things, is simply transform energy into particles. And so basically, any particle that doesn’t exist in nature, we can make in this way. You can make the antimatter electron by taking two particles, smashing them together. The energy sits there, and it will make an electron and an antimatter electron, and it just does. And we know that. The antimatter electron was discovered in 1932. This is all pretty easy. The antimatter proton was discovered in 1955 at the Berkeley Bevatron. And so this is just what you do. You can convert energy into a matter-antimatter particle. Now, the converse goes true, and that’s something we might talk about.

Is there some extremely precise recipe of being able to produce particular kinds of particles and all this kind of stuff? When you smash two things together, is there like how can you control accurately which kind of particles you’re trying to produce?

If you wanna make antimatter electrons, you smash together energy at a certain– It’s just easier with electrons because the electrons, to the best of our knowledge, have nothing inside them, so they’re simple. They have a certain mass, and that’s that. So if you smash particles together with the right energy, you can make them very, very easily because you can– It’s like an old style radio back in the day where you had to dial it in. You could get right on the station, and you could hear the signal, and if you were off a little, it didn’t work. The problem for things like protons and so forth is they’re not point-like particles. They’re kind of like garbage cans full of stuff, and so it’s very difficult to make antimatter protons.

Now, you can get more of them by increasing the energy at which you collide two particles together. If you’re at below a certain energy, and you say you collide two protons together at kind of low energy, you just don’t have enough energy to make an antiproton. And so it doesn’t happen. You get to a certain energy, and you can just barely make them. The more energy you collide them together, the more you make. So that is just sort of how it works. More is better.

All right? So Fermilab doesn’t make antiprotons anymore. We stopped making them in 2011, and it’s because we shut our big accelerator down to concentrate on a different facet of particle physics. However, at the time, we would smash protons with an energy of 120 GeV, and in that, we would make antiprotons. So that’s a ton of energy. It’s true that the CERN accelerator, the big accelerator, is now much higher energy than the Fermilab accelerator was. No problem. But that’s not how they make antiprotons. All of these big beam big laboratories, it’s not one accelerator. At Fermilab, there were five distinct accelerators, and it was basically like shifting an old standard car, ’cause you couldn’t just go zero to super speed in one accelerator.

You had to go from one to another, getting higher and higher. Well, at CERN, they use one of the, basically their second gear in their very big accelerator complex to make antimatter protons, and their accelerator is only 26 GeV compared to the 120 GeV at Fermilab. Fermilab’s not operating, but when it was operating, it operated at an energy about four times higher than what CERN is doing now. And why is that? Well, it’s because what CERN needs to do is to not make as many antiprotons as Fermilab did. They are doing a very different current experimental program. They’re doing a fascinating experimental program, including trying to figure out does antigravity fall up or down, which is kinda neat. And we sort of know the answer to that. That’s separate.

But anyways, so getting back to the antiproton business- … while Fermilab doesn’t do it now, it was top dog. It’s not anymore. The only really big antiproton accelerator creator is a small accelerator at CERN. Okay, so that’s the antiproton thing, and if we get back to antimatter, we can talk about that- … ’cause that is way cool.

But now the other side of your thing about making high-energy unknown particles, bigger is better. And it is true that the LHC is a very high-energy machine. It is about seven times more powerful in terms of energy per collision. It is also about 100 times more collisions per second than the Fermilab machine. So it is true that the LHC can make bigger, heavier particles that the old Fermilab, the Tevatron, ever could.

Don Lincoln
And that is true. So if you wanna look at high-energy stuff, yeah, you go to CERN now, which is why many of my colleagues, including myself, once we had measured all of the sort of frontier measurements we thought we could make with the Fermilab accelerator, we saw this bigger, more powerful machine with seven times the energy and 100 times more collisions per second. We said, “Heck yeah, let’s go work on that.” And to give you a sense of scale, the top quark, which is the heaviest particle ever discovered, discovered at Fermilab in 1995, there were two discovery papers, and the one on which I was a co-author, we had worked for a good chunk of between six months and a year of collecting collisions, and there were a lot of collisions, and our paper had 38 top quark candidates. 38.

Don Lincoln
And we knew that half of them were crap because when you make a detector like that, there’s what you call background, so you have the background and the good stuff, and we know it was about 50/50. So we had maybe 19 top quarks after working for between six months and a year of collecting data. But now, at the LHC, we make a top quark every second. And that’s what higher energy and more collisions per second will do for you. That extra energy, you’re above threshold, you make a ton of them, and when you compare the 1995 Fermilab accelerator to the current CERN accelerator, it’s probably 1,000 times the collisions per second. So it went from painstaking, pulling teeth, to, yeah, now top quarks are a background. We try to get rid of them. There’s just too many of them.

They get in the way of searching for the stuff we really wanna search. They are, like, so 30 years ago.

Lex Fridman
By the way, is there something to be said about the kind of signal processing here, how you remove the noise, how you remove the background, how you determine which particle is which? There’s probably some, like, incredible nuance there, even outside of the scope of this conversation.

Don Lincoln
So let me just throw some numbers out, all right? So at the CERN accelerator, when it’s operating, the collisions occur at a prodigious rate. We get about a billion, with a B, collisions per second. Now, each one of those col- Yeah, yeah, that’s what I said. Now, it turns out some of them are happening at the same time, so there’s about, of order 40 million moments in time per second where you would take a shot, and inside that moment, there might be 20 collisions. So that’s why, where we get to the billion.

Lex Fridman
Yeah, but can you individually pinpoint the collisions?
Yeah, but can you individually pinpoint the collisions?
Don Lincoln
Sort of, to a degree. So the beams are, you know… The– When people think of beams, they think of, like, laser beams, but that’s not really what particle beams look like. Particle beams look like little tiny sticks of spaghetti, except they’re much thinner. They’re not as fat as a stick of spaghetti, and they’re at the LHC, different accelerators are different, they’re about this long. And so you have one of them going one way full of protons- … and another one going the other way full of protons, and they pass through each other. And as they- … pass through each other, you should think of this as like a swarm of bees.

And this is like a swarm of bees, and mostly the bees pass through each other and don’t do anything. But every so often, some of the bees hit nose on and stripes and wings and everything everywhere.

That’s awesome. That’s awesome.
That’s awesome. That’s awesome.
Don Lincoln
And so as they collide through each other, you know, one collision’s here, and one’s here, and one’s here. And you can’t tell too much side to side because the beams are really small. They’re sort of the thickness of a human hair. But you can see along the direction. And they’re, you know, this is about the right size. And so we have detectors around them, and we can actually see, oh, particles came from here, and particles came from here.

Don Lincoln
And that’s amazing. All right. So at any one crossing, there’s maybe 20 collisions. Now, most collisions are absolutely boring. They’re boring because they exemplify physics that we know a great deal about already. We’ve tested it for decades. We know all about it. We don’t care. I mean, it’s kind of blasé that we can say, “Oh, yeah, yeah, we’re making a billion subatomic particles every second,” but who cares because, you know? But that’s just the way of frontier scientists. So what you need is you need to pick out the cool ones, the weird ones, the ones that nobody’s seen before. And so what happens is these things, these beams collide, and we surround the collision point with an enormous detector.

So these two giant detectors.

Right. So, but one of them, our detector, the CMS detector, it’s the small one. It is 70 feet long, 50 feet high, 50 feet wide. It’s five stories tall. It weighs 14,000 tons.

Small. ATLAS experiment is 150 feet long, 80 feet across. It weighs only 7,000 tons. Just piece of cake. You could take the ATLAS detector, and you could put four of them on a soccer or a football field, and it would fill the field up with just enough room on the sidelines for the cheerleaders and the water boy and the coaches and stuff. That’s how big they are.

Nice.
Nice.
Don Lincoln
So these are absolutely ginormous detectors, and basically they’re cameras, and what they can do is they can take pictures 40 million times per second. Now, all the data comes streaming off that detector, and we can’t record it all. It would just fill up all of our tapes, and it would be full of all these boring things we don’t care about. So what we do is as the beams pass through one another, we teach our detectors to say, “We only want one where there are certain configurations that might be interesting,” like there’s gobs of energy in the detector, or there’s a gob of energy on one side and nothing on the other side, or there’s four gobs of energy or whatever. These are called triggers.

Don Lincoln
And so these– what we have is fast electronics that take the 40 million possible pictures per second, and it says, “You know, about 100,000 of those are really cool. We should think about them.” And then it passes not all of the 40 million, but those 100,000 to the next level, which are commercial processors that have basically our final analysis code, but optimized to run very, very quickly. And what they do is they do a really quick and dirty analysis to further refine what’s good and what’s not. And that computer farm then accepts about 1,000 collisions per second, and we record those for further analysis. So that’s what’s really happening. Of the 50 million possible collisions per second, the fast electronics and then the computers pick the thousand.

And then we pass those through analysis software and hand them to the graduate students, and they pick through them, looking and finding the handful that are the next Nobel Prize. So that’s how that works, and that is truly astonishing. I’m– hats off to the accelerator builders, the detector builders, the people who make the software work, the people who make the not gigabytes, not terabytes, but petabytes of data flow around the world seamlessly. It’s really amazing. I’m very grateful.

Higgs boson discovery

So take me to July 4th, 2012, the discovery of Higgs boson.

Don Lincoln
So this is really fun because the people searching for the Higgs, it’s a, it’s a community, and the entire community knew that the LHC was coming online. So even though many of us had been working on the Fermilab accelerators, a lot of us were transitioning to the CERN accelerator. So we were in the very funny business of wearing our Fermilab detector people hats, trying desperately to find the Higgs boson at Fermilab- … while simultaneously wearing our CERN hats, knowing that CERN was going to be able to find it if it existed. And so, you know, we were a little neurotic, kind of wanted, you know, our old stuff to work and there was an awful lot of people on both experiments.

Well, that’s a possibility. I mean- … maybe the Higgs theory was wrong. Right? Until you, till you know it’s there, it might be wrong. It’s like dark matter. People talk about dark matter, it might not be real. I mean, I– it probably is, but it might not be.

If the mass was this, we’d get this thing. If the mass was this, we’d get this thing. But we could do the, the calculation for every conceivable Higgs mass, and so then we could search. Look, well, let’s say the Higgs mass is 100 in some units. Did we see it there? No. Then it’s not 100. Well, let’s look at 103. Is it there? No. So we could do that. Both accelerators could either find it or definitively rule out the predictions of simple Higgs theory, 100% guaranteed.

However, the CERN accelerator had 10 times the collisions per second and three and a half times the energy. So remember when I said it– with the top quarks, it was, like, six months for 19 versus one a second? There’s no question. The writing is on the wall. The LHC was gonna have an easier time of it- … if it was real. However, but, you know, I’m a Fermilab scientist, and we wanted Fermilab, you know, come on, we want Fermilab- … to win.

Don Lincoln
Not, you know. So we were busting our butt, and we had done what I said. We had ruled out this region. We had certain mass ranges. We knew it wasn’t there. And we finally said, if there was a Higgs boson, if it existed, which we didn’t know at the time, its mass was somewhere between, if I recall, between, like, 120 and 145. All right? We’d ruled out all the other stuff. And so wearing our CERN hat, we said, “Okay, we’re gonna find that.” But we were really, really, really trying to do it. Now, if we had had another two years or maybe three years of running the Fermi accelerator, Fermilab would have discovered or ruled out, or in this case, it turned out, discovered the Higgs boson, ’cause it’s a real thing. We would have found it without a question.

But we didn’t have enough data in July of 2012. We needed a couple more years. Unfortunately, in 2008, or fortunately, the LHC had turned on. It broke. They had to fix it. Turned on again in 2010. It ran poorly in 2011. In 2012, they pushed up their sleeves and said, “Let’s do this,” and it turned on. And so, you know, there was this– Fermilab knew if it didn’t have it now, it was too late. Anyways, 2012 rolls around, and like two days before the announcement at CERN was July 4th, so two days before that, Fermilab made a measurement and said, “We can rule out certain regions, but certain regions we can’t rule out. But what we know, and this is important, if the Higgs boson exists, it must be in this region for which we are not capable yet of ruling out.”

So detecting the, the Higgs boson confirmed the existence of the Higgs field, the mechanism through which fundamental particles like electrons and quarks acquire mass in the standard model.
So detecting the, the Higgs boson confirmed the existence of the Higgs field, the mechanism through which fundamental particles like electrons and quarks acquire mass in the standard model.
Don Lincoln
Correct. Although, let’s be very specific of what we did then. We found a particle consistent with the existence of the Higgs boson. There were alternative theories at the time that predicted not one, but multiple Higgs bosons. So there’s a theory called supersymmetry, which said that there was not one, but five Higgs bosons. The standard original 1964 Higgs theory says there were one. And so all we really knew at the time was we found a theory. We did not necessarily confirm that Higgs was right. We found data that said that it looked like Higgs was right, but until we ran for longer, we were unable to rule out other alternative theories. So that’s the deal.

Now, in the fullness of time, it is after all what, 14 years now later, we have been able to basically rule out some of those other things, and by now we have validated things. We found the mass of the particle. We know the spin of the Higgs boson. It has a spin of zero. We have discovered the Higgs boson decays. It preferentially decays into the heaviest particles it can through energy conservation. Can’t decay into top quarks, it’s too light to decay into top quarks, but it can decay into bottom quarks. It can decay into W and Z particles, can decay in a weird way into photons. And we have looked for all of the hypothesized decays of the original Higgs theory-

… and we have validated that it decays in those ways at the rates that theory predicted. And so now in the fullness of time, I’m pretty comfortable saying Peter Higgs and Robert Brout and François Englert and, and his colleagues, they were right back in the ’60s. But we weren’t sure on July 4th. All we knew was we found a particle consistent. But the thing is, with these discoveries, they’re often just barely discoveries. It takes a while to go and do the more complex, detailed measurements and, and that’s what we’ve done.

So at the time, I remember it being referred to as the God particle. You also had a minor in theology, so throwing that all together, so calling it the God particle is speaking to the importance, the potential importance of discovering this particle. Do you think that is in some degree justified? Like, if we look at the big impact of it on the, on the history of physics, how important was it to find and show that the, the, the Higgs field is real?

Well, I don’t think it is as important as, for instance, some of Einstein’s stuff. I mean, it was– it’s an important prediction. Like, the prediction of quarks was very important and interesting in validating this. The Higgs was kinda like validating that quarks existed. It, it’s an important stepping stone, and I, I do not wish to, to denigrate it in any way, but there’s ones that changed the way we thought about the world, like Einstein did. It wasn’t that sort of thing. And there is a funny story. So the reason they call it the God particle is this book by Leon Lederman, and if you read his book, he says, “Well, you know, we call it the God particle, but we should call it the goddamn particle because it’s been causing us so much trouble trying to find it.”

And Leon ran Fermilab, so– and he wrote a foreword for one of my books and, you know, I talked to him. He was a really funny guy. And the real truth was the book was called “The God Particle” because his publisher thought it would sell more copies. But, you know, then that got into the mindset of the reporters and so forth, and we called it the God particle. Leon never really thought of it as anything to do with the religious or even– I mean, he was an incredible jokester, the goddamn particle.

Right. It’s a huge thing, but it was part of the standard model. The standard model had known forces, it had known particles, it had all that. The Higgs boson, the one thing that is true is it was the last unvalidated piece of the standard model. The standard model does not answer all questions, which is why we have unanswered questions in physics, but it was a punctuation point, end of about 50 years of discovery and searching, where we finally were able to say the standard model, while incomplete, it’s mostly right as far as it goes.

Quick 10-second thank you to our sponsors. Check them out in the description. It really is the best way to support this podcast. Go to lexfridman.com/sponsors. And now, dear friends, back to my conversation with Don Lincoln. We did a whirlwind tour of the history of physics and took a little tangent on this incredible discovery of the Higgs boson. But we didn’t go all the way yet. There’s this dream of the grand unified theory, the GUT, that is a step towards the TOE, theory of everything. So can we talk about the GUT first? So what’s entailed in the GUT?

Don Lincoln
So the GUT is short for grand unified theory. We talked about that there were four known subatomic forces, the electromagnetic force, gravity, the strong force, and the weak force. And electroweak symmetry unification merged the weak force and electromagnetism into the electroweak force. So what GUT hopes to do is to merge the electroweak force and the strong force into one grand unified force. Now, that leaves gravity outside because gravity is seemingly fundamentally significantly different.

Then subsequently, it is hoped that at a higher energy, we will be able to blend the theory of everything together with all of the known subatomic forces, the strong, weak, and electromagnetic forces, and then gravity. But so, as you say, GUT is sort of a way station along the way. That’s the goal, and at this point, I would have to say that I do not see a fast progress in the immediate future. I think we’re a ways away from that at this point.

Speaking of which, string theory is the thing you’re referring to. So string theory posits that particles are tiny vibrating strings, and by tiny we mean extremely tiny at the scale of a Planck length. Then there’s other leading candidates like loop quantum gravity. Maybe there’s some alternate theories in the works. So can you link on that a little bit more? Do you think a theory of everything exists?

So I hold personally that there are rules that govern matter and energy, space, time, and they probably are rules that I don’t know. There are probably phenomena I’m not aware of. But I do believe that something, there are, is a rule that governs reality. And so in that sense, once we understand the rules that govern reality, the fundamental rules, that would be a theory of everything. You know, there are things that are unknowable, like for instance, inside black holes, we don’t know what’s inside there, but that doesn’t mean that there’s not something inside there. So there’s a distinction between what we can know and truth.

Whoa, whoa, whoa. That’s a pretty strong statement, right? That’s a pretty strong statement saying we’re fifty to a hundred years out from finding a theory of everything.

It took two hundred years to go from unifying gravity to unifying electromagnetism. It took a hundred years to go from unifying electromagnetism to unifying the electroweak force. Now, you could say, well, gee, that went from two hundred to a hundred, so it’s getting faster. But it’s also getting harder because the unification scale is of order ten to the fifteen, which—we can do the math. That’s a quadrillion times higher than the highest energy accelerator we can build today.

Don Lincoln
And it was one thing to, you know, we are reaching diminishing returns. We get something like a factor of seven increase in particle accelerator energy every twenty years. And so we have to get to a quadrillion times. Now, if you really did believe a factor of seven every twenty years, then that’s– we’re talking like five hundred years. But you know, this is like Moore’s law, that it doesn’t continue forever. We’re not going to every twenty years get another factor of seven. So yes, I think it’s a very long time. That’s my prediction. You know, some people are far more optimistic, and we can talk about that.

We should also, I should mention that I guess your intuition behind that is not just the part where you come up with a theory that’s beautiful and seems to be internally consistent, but you have to have a theory that’s making falsifiable, testable predictions.

Correct.
Lex Fridman
And you have to have a feasible engineering construction, a methodology for creating an experiment that tests that prediction. So I think a lot of your, this is fifty, a hundred, two hundred years from now, intuition is maybe about the second part of that, which is like, you need to have an experiment.

Yes. Yes. But you know, let’s say, I mean, you alluded to superstrings. I haven’t answered that question. I’ll table that for a moment. Superstrings is a fascinating idea. I don’t believe it, but I love it. I hope it’s true. And there’s a real, you know, aphorism, and it says you should absolutely never believe what you think. So even if you think superstrings is true, you shouldn’t believe it because it hasn’t been tested.

Now, let’s say superstring is correct. I mean, hypothesis, it’s correct, hundred percent correct. I don’t know it’s correct, so I don’t care. I mean, you know, it could be correct, but until it’s validated, it’s just a wild-ass guess, you know? So I, we have to have a way of validating it. So yes, the empirical side of it is important. I mean, you could wake up tomorrow and have the theory that is the perfect theory, but if I can’t prove it, I don’t care.

If we were to think, this is going back to the Great Courses on The Evidence for Modern Physics- … we’re talking about energy levels and tiny particles to the degree where the kind of prediction we would be making is not accelerator-type predictions. So it’s probably going to be impossible to build an accelerator that detects something like a string. So you have to make predictions about macro scale behaviors.

Do we even have intuitions about what kind of predictions they would be? So one, one of course, one of the lines of intuitions has to do with black holes or in the singularity. The physics of black holes combine certain elements of general relativity and quantum mechanics. So there- … you could see some kind of predictions you could make, but you can’t really mess with a black hole. It’s not like you can create a black hole in the lab.

So, you know, you can only see the outside of a black hole, not the inside of a black hole. So what you said, you did say something that was incredibly important and incredibly correct and probably won’t happen, but that’s still good, okay? So we have two choices. When you talk about superstrings, either superstrings are correct and they’re making predictions up at the Planck energy scale, at which point we have to somehow build facilities that can generate Planck energies. That’s possibility one. Possibility two is this theory, which is currently only applicable at Planck energy scales, someone figures out a way to take those equations and solve them in a way that, say, predicts the mass of the electron. Right? And that is a tricky business.

I am not a string theorist, so I can’t tell you that that’s likely, but I can tell you that they’ve been working on it since the ’80s and they haven’t gotten very far. Furthermore, I think it’s fair to characterize that string theory is still a vague idea, and that’s unfair, but let me tell you why I say that: because what they have are approximate solutions to approximate equations and that is already saying that we’re a ways away from really getting a handle on that. So yes, there could be some bright young lad or lass out there, someone listening to this podcast right now who figures out a way to take superstring theory and solve them in tractable ways that makes predictions from the scale at which they currently apply down to measurable scale today.

And if that happens, well, then I might retract my question or my concept. There’s a reason why I think that probably isn’t true. That’s probably not valid. So let me– I, I love this, all right? So let’s back up. I’m going to pitch. I wrote this book for Oxford, Einstein’s Unfinished Dream, and Einstein’s unfinished dream was to come up with a theory of everything. It was unfinished because, well, it’s unfinished. And so the second part, the tagline of that book is Practical Progress Towards a Theory of Everything, with the emphasis on practical because when you read books about theories of everything, when you see podcasts, when you listen to YouTube videos or whatever, they are often written by theorists. And theorists are– they’re big idea people.

They’re very, very smart, but there’s a pragmatism that is often missing in the sense that they say, “Well, superstrings, look, you know, have these little vibrating things, and wouldn’t it be cool?” And, you know, but you gotta get to the “do you know it?” So let’s pretend superstring theory or something like it is correct. The energy scale at which that should occur is of order 10 to the 15 times higher, 10 to the 19 GeV. We can currently do things at 10 to the fourth GeV, give or take. So that is 10 to the 15. That’s a quadrillion times higher energy. So what we are doing now is we are looking at the world with our very best measurements, and we are trying to project out a quadrillion times higher and figure out a theory that explains everything.

Now, I, I, I have this– I have a couple of analogies, but I like this. Suppose that you were some, you know, Joe Australopithecus 2 million years ago or something in Africa, wandering around somewhere in Kenya. Mm-hmm. Right? You’re about a meter in size, so you can walk a meter. Meter scale is like your scale. Mm-hmm. You can walk 10 meters in every direction. That’s 30 feet, no problem. You can work 100 meters, 300 feet. You can work 1,000 meters. That’s half a mile. You can work 10,000 meters. That’s 60 miles. 100,000 meters is 10 to the fifth and, and that, that’s unlikely. But the distance that we need to go from what we can see to the Planck scale, it’s not 10 to the fifth, it’s 10 to the 15th. So that means, in my analogy, think about this guy who’s walking around Africa.

Don Lincoln
Now, if he walks, you know, 100 feet or something, it looks a lot like what it is now. He can make a prediction about what he sees, and when he goes to that new place, it’s probably going to be okay. But if he starts walking 500 miles east, well, he, walking around the center of Africa, has no concept of, for instance, the Indian Ocean. He would never predict sperm whales or kraken. He would never predict what it’s like—the bottom of the ocean is going north. He’s in Africa. He would never, ever have a clue about the Alps or Antarctica. Going even smaller distances, going a mile up, things wouldn’t be very different. But if he goes 10 miles up, he wouldn’t breathe and he’d freeze. If he goes 100 miles up, he would die. If he goes two miles down, he would roast.

The point being is we are like that Australopithecus. We have a realm that we can study, and we can even predict to some validity what would happen if we go some distance away. But the farther away we go, the less and less our local prediction really represents the reality of those more distant times. And so basically, his theory about the world would be totally bogus. So even if he had the best theory, his theory would not have anticipated the Alps. It would not have anticipated penguins. Right? Flamingos, not there. Yeah. You know? And that is just the case. So now that’s what we’re doing. We are taking something and we have reason to understand what we know and we can predict a factor of 10 or 100.

Don Lincoln
But I think it is the absolute, the pinnacle of arrogance to think that what we can do given the understanding that we have from what we’ve measured now and predict it out a quadrillion times higher than we can see now. So my opinion, and this is partly because I’m an experimentalist, the correct way to make progress—practical progress towards a theory of everything—is to look around at the things that we don’t have answers to right now. For instance, are there some things smaller than quarks? I don’t know. Is dark matter real? I don’t know. If it’s real, what is it? I don’t know. Is dark energy real? Yes, probably, but I don’t know. What is the nature of space and time? I don’t know.
But I think it is the absolute, the pinnacle of arrogance to think that what we can do given the understanding that we have from what we’ve measured now and predict it out a quadrillion times higher than we can see now. So my opinion, and this is partly because I’m an experimentalist, the correct way to make progress—practical progress towards a theory of everything—is to look around at the things that we don’t have answers to right now. For instance, are there some things smaller than quarks? I don’t know. Is dark matter real? I don’t know. If it’s real, what is it? I don’t know. Is dark energy real? Yes, probably, but I don’t know. What is the nature of space and time? I don’t know.

But these are questions we can explore, and I would expect, and this is my prediction, that, all right, we’re gonna figure things out at a factor of 10 or 100 times better than we can do now, and we might be able to do that in my kid’s lifetime or something like that. But in order for us to predict a quadrillion times higher, I’m pretty sure superstring theory is wrong. Not because people aren’t smart, but because something new is going to happen. I mean, if you were talking about chemistry, you would have never predicted nuclear physics, and that’s a small increase in energy, right?

The idea that there’s something in the nucleus of atoms that causes the sun to burn, there’s a reason why people didn’t believe, you know, they, they calculated how old the sun should be, and it should only be 10 million years old because otherwise it would burn out. Well, that’s clearly wrong, and it’s wrong because of nuclear physics. That is why I feel fairly confident to say, while someone could think, well, superstring might be right or something, and maybe it’s right, and I hope it’s right. It would be awesome if it’s right. But what are the odds when you’re making something with that tiny lever arm, predicting it out a quadrillion away and say, “Oh, yeah, we got it right.” What are the odds? And my answer is, you gotta be kidding me.

Now, I could be wrong, and I admit that I could be wrong, but that’s why I think the real issue is not the brilliance of humanity. It’s the stuff we haven’t found. We don’t know– I mean, the simple one, and I’m say it simple, and it’s not, but what is dark matter? We don’t have a bleeping clue. Not a clue. We know a lot of what it isn’t, but we don’t know what it is. And so, you know, talk about superstrings. All right, well, maybe dark matter fits in superstrings, or maybe dark matter is governed by a physics that is completely diametrically opposed to the superstring concept.

And allow me a bit of a thought experiment here, a brief thought. My intuition says that when you propose a theory of everything, the kind of prediction you want to make involves a kind of leap of conceptual understanding that Einstein did. So, for example, you want to come up with something like space time and then gravity-

I mean, to come up with something like space time, you know, there’s one idea, for instance, to say that space and time aren’t real. They emerge from entropy. Yeah, that’s a way of, a new way of thinking, and maybe there’s some validity, and I want people to think about it. But in the end, it’s just an idea, and that’s the real key thing. And, and as you say, it has to tie to a macro world. You have to validate. If you don’t validate, it’s a crazy idea. Theorists are incredibly creative, smart, wonderfully interesting people, but I don’t care. I want a measurement that validates the idea because there are so many– I mean, if you read the journals, there are so many theoretical papers with all these nifty ideas that die.

You know one that was recently I liked and, and might still be true was that dark matter that, you know, our simple model of dark matter is that there’s a subatomic particle out there that’s heavy, and it’s floating around, and it’s causing gravity. But someone said, “Well, you know, maybe there’s complex dark matter,” which means there’s a whole dark sector, so there are dark atoms, and they interact with one another. And that is a nifty idea, and I love it. And that was all the rage for a while, and we looked at it, and it may still be true, but the simple ideas have been mostly invalidated because we’ve tested it and it doesn’t work. Same thing, there was a talk about large extra dimensions.

The reason that gravity is so much weaker than the other forces was, well, maybe gravity can sneak into more dimensions than the other forces.

And there are two directions. You’re talking a top-down. Someone comes up with this big idea that’s testable. But you also have the other way that science advances, and it’s not with a theory that is then tested. It’s with the, “Huh, that’s weird.” For instance, either in, in the 1930s with Fritz Zwicky or in the 1970s with Vera Rubin, she did a simple thing. She said, “How fast are galaxies rotating?” ‘Cause it’s an easy thing to calculate. You could literally calculate that with high school physics. And you get an answer, and then you measure it, and it’s wrong. And so I’ll– That, that’s the, wow, huh, I don’t know what that is. And that led to the hypothesis of, of dark matter. Now, dark matter is not a theory of everything, but it’s a clue. It’s a powerful clue.

We should pull, tug at that thread. Maybe our entire theoretical edifice unravels, or maybe it doesn’t. Maybe it’s just a snag, and we can fix what we have now. I’m not sure. So that’s another option is to simply look at many measurements that are very precise and find ones where the outcome and the prediction with established theory disagree, and that is a clue.

Before we leave the topic, we gotta talk about string theory. In your view, is it basically dead? As I understand one of the primary flaws of string theory, outside of the testable experiments that we’re talking about, is because it relies on these unobserved extra dimensions, there was a hope that it uniquely could explain our universe, but it turns out this, quote, “landscape,” there’s an enormous so-called landscape of possibilities it leads to. And so it renders the theory basically unpredictive, ’cause it can describe all kinds of universes-

I agree to a degree. But I bring it back to my prior objection. It is absolutely true that superstring theory at, in its current manifestation, aside from the extra dimensions, which are some level small potatoes, it allows for an extremely large number of possible universes. But if we were able to take those predictions and somehow connect it to a physical measurement, then what we would do is we’d lop off those alternatives. We’d throw them away as saying, “Well, you know, those are like an equation, you know, X plus five.” I can put in any number I want in there, it doesn’t matter. But if X plus five equals nine, then I’ve ruled out a whole bunch of numbers except four.

And so this is a case of string theory does allow for many predictions, but if we could rule them out by connection to a measurement, then it would no longer do it. We would modify string theory, and we would retain the vibrating string concept, which I really, really like. I mean, I really like it. But until we can validate this, we can’t. So now you ask, is it dead or not? In my opinion, it is very difficult to kill such a theory. I mean, really, truly kill it, ’cause kill it means make a prediction and it fails. But what can happen and what is happening is people have been working on it since the ’70s. So we’re talking of order 50 years, people have been working on it, and it has not solved the problem.

And so I think what’s happening is people are looking at that and saying, “I, do I wanna spend my life working in this direction with the very likely possibility that 30 years from now we’ll be not much farther along than we are now?” It’s a lot like back in the 1940s when people started thinking about the meaning of quantum mechanics. And I wanted to do that when I was a kid in, in the ’70s. But then when I went to grad school, I realized that people, very smart people, people smarter than me, had been working on that for most of their lives and made no definitive progress. And so you have to decide, as a scientist who wants to answer questions, do I really wanna take on a question that is so hard that it will not be answered in my lifetime?

You know, many of those theories are espoused by passionate people. They have fans. People love them, but they don’t do what science needs to do, which is make predictions. Now, loop quantum gravity is a little different. That one is better developed, and that one is not a theory of everything, so we should make that clear. Loop quantum gravity is not a theory of everything. It is simply a theory of quantum gravity, period. It does not aspire to include all of the known forces. It simply tries to take gravity, which is currently intrinsically, it treats space as smooth and continuous. For those of your viewers who are mathematically inclined, in Einstein’s theory of general relativity, gravity is infinitely divisible.

There is no smallest bit, and so essentially the laws of calculus apply. However, it is possible that at a small enough scale space is no longer divisible in the same way that you can, you know, take a cup of water out of a swimming pool and then a quarter a cup and so forth. But eventually, once you’ve taken out a single molecule of water, you can no longer take out a smaller thing. So loop quantum gravity attempts to quantize gravity, so that’s what it does. And so this is unlike string theory, which attempts to bring gravity in with the other forces. And in fact, the reason, the fundamental, the one reason why string theory became so interesting to the theoretical community is string theory was not being developed as a theory of everything.

It was being developed as a theory of the strong force, and it was in competition with QCD, which is the currently accepted theory of the strong force. And it turned out the two groups, the string theory groups and the QCD groups competed for a while, and string theory basically failed the race, and people paid attention to quantum chromodynamics, QCD. But then somebody noticed in string theory that one of the things it predicted was a zero mass spin-2 particle. And you can prove that any zero mass spin-2 particle is the graviton.

And so if you see a theory that has a zero mass spin-2 particle, you now have a candidate for dragging gravity in, and then, oh my gosh, people got terribly excited because now this theory, which was working in the direction of the other quantum forces, brought in gravity, and now it was a candidate theory for everything. But that’s not what loop quantum gravity is. Loop quantum gravity is simply trying to understand the nature of space itself, which is already a fantastic thing. And, you know, I talk to Rovelli every so often. I write about his theory and I point out some of the issues with the theory, but I’m usually about, like, two months behind as he and his colleagues are developing and so forth.

‘Cause one of the things is originally loop quantum gravity predicted that the speed of light would not be universal. The speed of light would depend on the frequency of the light. So high frequency would travel at one speed, and low frequency would travel at a different speed, and it had to do with the wavelength of light basically interacting with the structure of space if, you know. And so that was an issue with loop quantum gravity.

And so if you look at gamma ray bursters, which are, you know, super explosions of astronomical events that are a billion light years away or more, and they spit out light in all wavelengths, and if that loop quantum gravity prediction were correct, when you saw one of these gamma ray bursters, you would see the wavelength of one light appearing on Earth at a different time than another wavelength because of the different speeds, and that wasn’t the case. They appear at the same time. And so I went on to say, “Well, this pretty much killed loop quantum gravity,” only to get a prickly note from Mr. or Dr. Rovelli saying, “You know, we’ve disproved that. We’ve changed the theory.”

That’s no longer true, and now that prediction, that old prediction of loop quantum gravity is no longer valid.” And so that observation of the uniformity of the speed of light no longer kills the new loop quantum gravity. It would’ve killed the old one, but it didn’t kill the new one.

There was another brilliant observation recently. Love it. The observation of gravity waves. And it was from two neutron stars orbiting and coalescing. And so they made gravitational waves, fantastic, but they also, because they were not black holes, they were neutron stars, they hit and exploded, gave off a tremendous bright flash of light. And so astronomers saw the flash.

Gravitational wave astronomers saw the ripples of space-time. It was 140 million light years away, which means light would’ve traveled 140 million years to get here, and the two incidents, light and gravity, both arrived within 1.7 seconds of one another. And that tells you that gravity travels at the speed of light. That was a brilliant, fantastic measurement. Now, we thought gravity traveled at the speed of light, but now we have a measurement, we proved it, and damn it, I am impressed.

Physics of empty space
Lex Fridman
Our universe is so fascinating. Speaking of which, since we brought up antimatter, we’ll have to talk about it. You’ve talked about it in several of your lectures from different angles, including the dark energy crisis and including empty space and vacuum and so on. So let’s look at the empty space angle. So you know, it turns out that empty space is not empty.

That’s a hard, hard question because we don’t know what space is. But let’s start out-
That’s a hard, hard question because we don’t know what space is. But let’s start out-
Don Lincoln
… let’s just start out with something simple. We’ll assume that space is not quantized, okay? Now, it probably is, I don’t know, but, you know, we gotta start with somewhere. So let’s start out with sort of the space of calculus, the space that you can divide forever. The modern version of quantum mechanics is called quantum field theory, and it postulates that, A, space exists. Then it postulates that within space there exist fields for every known subatomic particle. So there is a photon field, there’s an electron field, there’s an up quark field, there’s a down quark field. There’s all the fields. And those fields can vibrate, and when they vibrate, those are the subatomic particles. So an electron field vibrating in a characteristic way is an electron.

Don Lincoln
Now, it’s also possible for the electron field to vibrate not in the characteristic way, but in a way that’s still vibrating, but it’s not an exact electron. So this is what we call virtual particles. Now, virtual particles, there are lots of ways to talk about them, and the way I’m talking about now is the most correct and the most sophisticated way that we can talk about them. I will talk about them briefly in a simpler way to help. But right now, that’s the important thing, is that there are these fields. Specific vibrations are the known particles. Vibrations that are a little different are these virtual particles. They’re particles that don’t truly exist. And so that is what we think space is. There is all of these fields.
Now, it’s also possible for the electron field to vibrate not in the characteristic way, but in a way that’s still vibrating, but it’s not an exact electron. So this is what we call virtual particles. Now, virtual particles, there are lots of ways to talk about them, and the way I’m talking about now is the most correct and the most sophisticated way that we can talk about them. I will talk about them briefly in a simpler way to help. But right now, that’s the important thing, is that there are these fields. Specific vibrations are the known particles. Vibrations that are a little different are these virtual particles. They’re particles that don’t truly exist. And so that is what we think space is. There is all of these fields.
Don Lincoln
They’re all vibrating a little. If you insert the right amount of energy, you can get it to vibrate in the characteristic way and make that subatomic particle. But even when you don’t—There is the particles, I mean the fields are there and they are vibrating. So those vibrations are what we called virtual particles. Now, your viewers may have heard of virtual particles in other ways, in which case it says that space is just empty, and what happens is matter and antimatter particles briefly appear for a very short period of time before they coalesce back again and disappear and re-emerge back into the field. And so these are both correct.

Don Lincoln
So what happens is, is that’s what quantum field theory says, is it says that these ripples are appearing or these particles are appearing and disappearing. And so that just sounds nuts. You look at empty space, you’re not seeing anything happening. But they’re happening fast enough that they can’t be seen, but they do have consequences. And there are two experimental measurements that I can think of that validate that this thing that sounds crazy is really happening, and one is called the Casimir effect. So in the Casimir effect, you take two metal plates, the parallel plates, and you put them near one another, very, very close.

Don Lincoln
Now, if this is the case, if, if these virtual particles exist, then in between the plates, these particles appearing and disappearing, and outside the plates, the particles are appearing and disappearing. However, because these plates are close to one another, this puts a constraint on the wavelength of the particles that can occur between the two plates because they, the particles cannot extend outside the plates. So the short wavelength particles can exist inside the– between the plates, but the longer ones cannot. However, outside the plates, there is no constraint, so short wavelength and long wavelength particles can exist there.

Don Lincoln
And the net effect is there are more virtual particles outside and less particles inside, and therefore you have a net pressure which would then push those two plates together. That is a prediction we’ve been talking about, and guess what? It happens. Those plates push together. So that is a validation for the existence of these particles in empty space. Now, there is another measurement, and this changes the magnetic properties of particles like the electron, the muon and so forth. And so this was discovered in nineteen forty-eight. So if you take old school standard quantum mechanics you know the spin of an electron, you know its charge, you can calculate its magnetic moment, and it comes out to a number.

If you do the measurement, what you find is the measurement disagrees with the quantum mechanics, the nineteen thirties quantum mechanical prediction by point one percent, and that was measured in nineteen forty-eight. And people went, “Huh.” So this happened at Shelter Island Conference in New York. And on the way home, someone who saw the, this measurement thought about it, and they invented what we now call quantum electrodynamics. So old quantum mechanics quantizes matter. The second quantization quantizes both matter and the fields, in this case, quantized the electric fields.

And so in this quantized field, it predicts that surrounding a bare, say, electron, which is spinning and has a, has a charge, there is this, this bath of particles, virtual particles appearing and disappearing all around it. And the ensemble of all of those particles appearing and disappearing will alter the magnetic properties that you can measure for the subatomic particle, and it changes it by point one percent. And we have measured this, and we have not measured this imprecisely. We have measured the magnetic properties of both the electron and the muon to twelve, count them, twelve significant figures. And the theory and the data agree number for number for ten places.

Don Lincoln
And then once you get out to the very end where both the theory and the data have some imprecision, they then disagree. And so maybe there’s some interesting stuff going on there. But ten figures, it’s just staggering.

Correct.
Antimatter
Lex Fridman
Can we just talk about the antimatter part of that? So starting with Paul Dirac, one of the most legendary examples of math leading to physics. So the math suggesting that something like an antimatter should exist, and Paul Dirac taking it seriously and then eventually showing that it does exist. So what evidence do we have for antimatter?

Don Lincoln
So antimatter was predicted in nineteen twenty-eight. Paul Dirac was trying to merge quantum mechanics and relativity because the original Schrödinger equation did not, was not relativistic. And in doing so, he basically, the equations were complex, but in the end it came down to something like equation squared equals one. You take the square root of both sides, you get equation equals plus one or minus one. Plus one was the electron, minus one was something. He didn’t know what it was. There was some conversation for a while, thought maybe it might be the proton, but that didn’t seem to work out.

Don Lincoln
And so he insisted that his equations were right and that there was an antimatter, he didn’t call it an antimatter, but a positively charged sibling of the electron, what we now call the positron, the antimatter electron. So it was predicted. It was discovered in nineteen thirty-two by Carl Anderson and his student Seth Neddermeyer. They saw an antimatter electron. And that was pretty cool. So that right there, they knew it was real. Antimatter was predicted, it was observed, that’s that. In nineteen fifty-six, the antimatter proton was created, and that required a large particle accelerator, high enough energy to make it, and that was done at Berkeley. And a year later, the antimatter neutron was discovered.

Don Lincoln
So at this point, and now jumping ahead to now, we can make, using energy by smashing particles together, we can make antimatter protons, we can make antimatter electrons. We have gone so far to make antimatter helium nuclei. So we have made two antiprotons and two antineutrons, combined them together to make an antimatter helium nuclei. This has been done, been observed, no question. At CERN, they have gone so far as to make antimatter hydrogen. They take a beam off one of their lower energy accelerators. They make antimatter protons. They collect them, they slow them down, they cool them to almost absolute zero. They take sodium-22, which makes antimatter electrons.

They slow them down, they bring them together, they coalesce them, and they make literal antimatter hydrogen atoms with an antimatter proton surrounded by an antimatter electron. And they have done incredible measurements. They have agitated the atoms and caused it to emit light. They have looked at the light that comes out of antimatter atoms. And the question is, is does the light coming out of antimatter hydrogen atoms have exactly the same spectral characteristics as ordinary hydrogen, which we predict that it does? And the answer is it does. So the tests have been staggering. We now know a great deal about antimatter hydrogen.

Recently, recently like twenty twenty-three, I believe it was, one of the experiments called ALPHA at CERN made antimatter hydrogen, put it in a bottle and released it and watched which way it would go. Did it fall up or did it fall down? Because while it kind of makes sense maybe to think that maybe antimatter falls up in the same way that we have Coulomb’s law, you’ve got electric charges, and they might attract or repel. However, there was lots of ample theoretical reasons to believe that antimatter also would fall down.

Don Lincoln
So they did this fantastic measurement, and they first they put in hydrogen, and they calculated that if they did this, something like eighty percent of the hydrogen atoms would fall through the bottom of the bottle, and twenty percent would go through the top just because gravity is very weak and the atoms will escape wherever they do, but there will be a bias pulling hydrogen atoms down. So they did exactly the same thing, and what did they find? They find that antimatter falls down. Now, they do not have a good enough measurement at this time to say that the gravity that antimatter experiences is one hundred percent that of matter.

Don Lincoln
What they have measured is that antimatter fell down with a seventy-five percent the strength of regular matter, but there were big uncertainties. There was plus or minus point one three due to the experiment, which was good but imperfect, and plus or minus point one six due to their theoretical model. So it’s like point seven five plus or minus something like point two nine. And that means there’s a good chance it’s between point five and one- … which means it’s consistent with one. So they are improving their measurements.

Lex Fridman
Well, if I can, I would love to take a bit of a tangent on that topic ’cause I went down a rabbit hole watching some of your videos on antimatter. And I mean, Fermilab was the hub for the production of antimatter for quite a while.

Lex Fridman
I saw that NASA said that the global estimate for the current rate of production of antimatter is one nanogram per year. Can you speak to how hard was it to make antimatter? And also, you did mention in a video that, you know, if matter and antimatter meet, they produce a lot of energy. I think twenty grams of antimatter is equivalent to a one-megaton nuclear warhead in terms of explosive energy. Yeah, so all of those questions together. So how hard is it to produce antimatter?

Don Lincoln
It’s freaking hard. Okay. All right. So here’s the deal. So at the time until two thousand and eleven, Fermilab was the most powerful antiproton production facility on the planet. Every two point three seconds, we would smash ten to the thirteen protons into a target, and we would get out ten to the eighth antiprotons. So basically, in order to get a single antiproton, we needed to smash a hundred thousand protons into material. So every two point three seconds, we would get of order ten to the eighth antiprotons. And what we would do is we would collect them over the course of twelve hours or so, and we would get, in the end, we would have to collect them and cool them down and so forth, of order ten to the twelfth antiprotons every twelve to twenty-four hours.

Don Lincoln
So ten to the twelfth sounds like a lot. It really does. That is a trillion. But you need to remember that a gram of antimatter is ten to the twenty-three antiprotons. So that means over the course of a day, we were able to create something like one hundred billionth of a gram. And so if we did that for a year, then that would be about a nanogram. So about a nanogram a year, give or take. That’s a reasonable estimate. So a nanogram, one billionth of a gram, so that means at that rate, with that facility, it would take a billion years running with very little downtime to make a single gram of antimatter. If you combine one gram of antimatter and one gram of matter together, the energy release is equivalent to the combined Hiroshima and Nagasaki explosions.

So that tells you if you wanted a megaton, you need about 25 times more. So you would have to run for 25 billion years to get a megaton of explosive power.

Let me lay it all out, because I think it’s pretty interesting actually. This is a NASA estimate of how much it costs to produce antimatter. So looking at all the, the, the costs of the accelerator, all, everything combined together, to do enough for a one-megaton antimatter bomb, if such a thing would be even possible, on the order of 25 grams, like we mentioned-

… will cost about, based on the NASA estimate $1.5 quadrillion. By the way NASA wasn’t talking about a bomb. It’s just me adding— NASA was talking about the estimate, the cost of 62 to 63 trillion dollars per gram of antihydrogen, actually is what they’re referring to. So compared– I was looking at estimates, the current best estimate is how much it takes to produce a one-megaton nuclear warhead. Everything combined is about 10 to 50 million dollars in the United States. So you’re talking about difference in terms of a weapon with equal power, 50 million dollars versus $1.5 quadrillion. To me, what’s interesting, weapons is just one indication of this. One other possibility, and NASA also writes about this, is the use of antimatter in propulsion systems.

Just like you can use nuclear fission and maybe even nuclear fusion down the line. In propulsion systems, I saw that one gram can help get us to Alpha Centauri star system if we can get to 0.2 times the speed of light in 20 years. Meaning it would take us 20 years to get to Alpha Centauri. Is any of this a possible future, the use of antimatter for generation of energy? Because we should mention that it’s extremely compact. It has the obvious downsides that it’s extremely costly to produce. We don’t know how to do that kind of scale. The upside is it’s compact.

Right. So if you were unable to contain your trip to Alpha Centauri for even a millionth of a second, boom, that would not be good. You know, it reminds me of the Star Trek where Scotty’s saying, “Captain, you know, the antimatter pods are about– look, we’re losing containment. It’s gonna blow.” And that’s exactly what would happen. So the short answer is yes, antimatter as, in principle, we could make and use as a source of energy. But there are probably far less expensive sources of energy. You know, it depends on what you need to do. The Voyager probes are still chugging along with plutonium. Now, they’re running out of energy at this point, but we could, you know, presumably do a somewhat better job if we needed to.

So I like the idea of antimatter, you know, but the reality is the danger, not the obvious danger of weapons, but the danger of if you wanted to be in a ship run by antimatter, if it ever got loose, well, you would never know it. That would be that.

The reason I find this kind of inspiring is antimatter is in the space of physics that has a lot of mysteries. There’s a lot of exploration to be done. And so this kind of connection to energy means that if we have a bunch of breakthroughs on the antimatter side, that might lead to a better propulsion system, better energy generation systems.

And remember, we’re talking concentrating it into volumes the size of a proton. I mean, if you concentrate it to the size of your thumb, well, then, you know, it’s really the density that matters, the local density. And so when you smash two protons together, all of that’s occurring in a tiny, tiny volume, so it’s the local density of energy that matters. If you had a lot of energy in a thimble or something- … It’s probably not dense enough. You know- … it really has to be in close proximity for that to happen, and then when it does, it’s okay. So if there’s another way, we know how to do it, to make that density thing with accelerators. If someone has a bright idea on how to make highly dense energy, then yeah, making antimatter is a piece of cake. But that’s the crux-

So one of the big mysteries with antimatter is the bigger why. Where is the antimatter that should kind of be there if the whole idea is that anytime you generate matter, you generate the same amount of antimatter, and yet when we look out into the observable universe, it seems like there’s not antimatter for the most part there.

Correct.

So what do we understand about this mystery? What are the possible explanations as to why?

Don Lincoln
So there’s this thing called baryogenesis and, as you say, so reiterating a little bit what you just said, these are both Einstein things. Einstein says that when you take energy, you make matter and antimatter in equal quantities, and Einstein says after the Big Bang, there was a lot of energy in the universe, which should have made matter and antimatter.

We only see matter. Where’d the antimatter go? And the answer is, we don’t know. However, there are some ideas, and there’s a lot of thinking on it, and in fact, for me, it’s doing an experiment right now with neutrinos, trying to better understand what it was that made the matter and antimatter not be the same. Now, we do have a measurement of how much different it should be, and it’s kind of neat. We can do this by counting the number of protons in the universe, just looking at galaxies and so forth, and then we can look at the cosmic microwave background, which is sort of the aftermath of the Big Bang, and we can count the number of photons from the cosmic microwave background.

And with a little bit of math, what we can do is we can then say that somehow in the early universe, something made a very, very tiny asymmetry, so that for every billion, billion with a B, antimatter particles that existed in the universe, there were a billion and one matter particles. The billions canceled, annihilated, destroyed each other, and that extra one that’s left over is us.

Don Lincoln
And so what physics mechanism made that ever so slight asymmetry is not understood. There are some thoughts. One thought is that, well, it’s just how it was. When the universe was formed, there was an asymmetry. It was not made by matter and antimatter. Another possibility is there are various numbers of theories all under the word baryogenesis, baryo coming from the word baryon, which basically means protons, and genesis meaning the creation of, and we’d say that simply because the protons are the heaviest particles. And so baryogenesis is just the creation of matter. And there are just a number of theories in quantum mechanics that say that matter and antimatter can oscillate back and forth into one another, and there is a slight, slight asymmetry in how that happens.

And we know that this is true to a degree. We’ve measured it in the 1960s with a different form of matter. I mean you know, not protons, but a type of ephemeral matter that only exists in particle accelerators. And so we know that there is a slight difference between matter and antimatter, but it’s not enough. It doesn’t explain that. We’re not sure. So at Fermilab, we have this idea which kind of turns things on its head, and it’s not baryogenesis, it’s leptogenesis. So leptons are the electrons. And because Fermilab is currently the world’s most powerful neutrino accelerator, and neutrinos are leptons, there is this idea. Now, leptogenesis is incredibly complicated, but the idea is that it is possible. We know that neutrinos actually change their identity.

There are three different types of neutrinos like I don’t know, cats and jaguars and tigers, and if you have a beam of just cats, if you go along a little while, you find there’s cats and jaguars and then tigers, and then they’ll be back to all cats again. And so this oscillation thing is called neutrino oscillation. We’ve known it’s been true since 1998, and what we are studying is we’re going to make a beam of neutrinos and another beam of antimatter neutrinos, and we’re going to study the oscillation behavior of the two of them. And it is possible, it is unlikely, but it is possible that the two of them will oscillate at slightly different rates.

And if the neutrinos oscillate at slightly different rates, then that, along with several other highly improbable things, can tie together and might explain why there is more matter in the universe. So if I was gonna bet the farm, I’ll bet that they oscillate at the same rate, but I don’t know, and you don’t know till you do the measurements, so that’s what we’re doing. There are some other experiments trying to measure it right now, so there’s a big race between the Fermilab group and another group in Japan to see who gets there first and make this measurement, and we will find out. If it turns out, though, that there is a difference in this oscillation rate between matter and antimatter, it will be a huge clue in this very, very difficult puzzle.

I wish I could tell you I knew what the answer is, but literally nobody knows. I mean, and that’s the thing of being a research scientist like me is if you’re not confused- … you’re not doing your job.

Dark energy
Lex Fridman
This is one of the areas of physics where there’s a lot of mystery. Okay. So can we pull at that thread a little further? Let’s talk about our intuition of what is dark energy as it connects to empty space and everything we’ve been talking about. What’s—what’s the cleanest definition of dark energy?

Don Lincoln
So dark energy is either energy of space or energy in space. The most common statement is the energy of space, and it is essentially a repulsive form of gravity. And we believe this is real, and the reason we believe this is real is from observation. This is one of those things where we talked about a while ago where I said that, you know, you can think about things up this theoretical stuff and try to come up with a measurement, or you can make measurements and see where they disagree with predictions and lead that in a direction. So back in the late 1990s, some astronomers were looking at the expansion rate of the universe.

Don Lincoln
So the Big Bang occurred, the universe is expanding, the universe is full of matter, matter attracts, so the gravity due to the matter of the universe should slow the expansion of the universe. And the only question was how much? There were three possibilities. The possibilities were there was so much gravitational force that the expansion of the universe would slow, stop, and be pulled back together in a big crunch. Number two was that the universe would continue expanding, slowing down, but never really stopping. And then the third possibility was the exact critical case, where expansion would slow forever and approach zero only at infinity, never quite stopping or reversing. So those were the possibilities, door number one, two, or three.

Don Lincoln
So they did the measurement, and what did they found? It was door number four. The universe was not only expanding, but the expansion was speeding up, and the only way that could happen, given that gravity slows it down, is there was a repulsive force, and the name we give to that repulsive force is dark energy. This is something that Einstein postulated early on in his development of general relativity, but then because at the time, he knew that his theory predicted that the universe would collapse but he believed the universe was eternal and not unchanging, and so he needed something to counterbalance that collapse, and so he invented dark energy. He didn’t call it that.

Don Lincoln
Called it the cosmological constant. But then a few years later, Edwin Hubble discovered that the universe was indeed expanding, and so since the universe was no longer static, Einstein said, “No need for cosmological constant,” took it back out. Thought it was a dumb idea that he put it in, and was embarrassed. However, in 1998 it became clear that his original idea that there should be some sort of repulsive form of gravity was real, and it’s put back in the theory.

And so that’s what it is. We are pretty confident at this point that the expansion of the universe is speeding up, and the thing driving it is dark energy. Now, what is dark energy? I don’t know. As I said, the most common thought is that it is the energy of space itself, but it is at least conceivable that there is a field in space where space exists- … and that field is pushing space apart. That’s another conceivability that I’m not sure that we have the instrumentation to distinguish, but that’s not what normally people think. People think it is literally a property of space.

Don Lincoln

Lex Fridman
… a nice little insight about the complicated nature of dark energy. So the observations, as you describe, say that empty space has a tiny energy density that accelerates expansion of the universe. But quantum field theory’s prediction for what vacuum energy should be when coupled with gravity is much larger. So this is what makes for the quote—you have a video on this—worst prediction in physics.

Can you, can you explain this crisis?
Can you, can you explain this crisis?
Don Lincoln
Well, there’s a measurement, and you can measure how fast the universe is expanding, and from that you get a measurement of dark energy. However, if you then say, well, suppose the dark energy is due to fields in space. So that’s quantum field theory. Hey, I know a lot about quantum field theory.

Don Lincoln
And so we can take the quantum field theory, and we can calculate what the density of energy is due to quantum field theory. And basically what you do is you take within a volume all of the wavelengths, the longer wavelengths, the shorter wavelengths, the shorter and shorter, and you can add them all up. And each wavelength adds a certain amount of energy, and if you add that all up, then you get a number, and that number is the rather embarrassing 10 to the 120 power times—that’s a one with 120 zeros after it—bigger than the measurement of dark energy. So you go, “Yuck, that is not fun at all.”

Don Lincoln
And that is because the equation comes to the highest energy or the smallest wavelength particle that you can imagine to the fourth power, since anything to the fourth power is a big deal. So that’s where you get that awful number. Now, if it turns out that there is some new physics that’s just about at the energy scale we can measure using our biggest particle accelerators, remember I told you that that was a factor, the maximum energy scale, Planck scale, is 10 to the 15 times bigger than what we can measure now. So let’s say that we don’t have to calculate up to the Planck scale because something happens, something changes at the energy that we know right now.

So let’s say that we don’t have to calculate up to the Planck scale because something happens, something changes at the energy that we know right now.
Don Lincoln
Well, then that means we don’t have to integrate to Planck scale, we integrate to 10 to the 15th less of the Planck scale, and this thing is to the fourth power, so 10 to the 15th to the fourth power is 60. So now, even if we say, you know, Don, he’s brilliant, he’s gonna find something at the LHC tomorrow that’s gonna solve all this problem, now we’ve solved it, it’s much better. It’s only different by 10 to the 60 power, which is still pretty bleeding big. So the short answer is there is very clearly something going on, something wrong, very badly wrong in the quantum field theory. You know, we have to have, maybe there’s another field that balances out the energy, that cancels it down. And even that, you know, that’s not so outrageous.

You know, you could imagine that there’s another, you know, like we have matter and antimatter, they balance pretty well. Okay, maybe there’s something going on, you could cancel that out, that’d be perfect. But canceling something to zero is easy ’cause, you know, plus one and minus one, zero. Plus two, minus two, zero. But we still have dark energy. Dark energy is a little bit, so if it cancels, it doesn’t cancel exactly ’cause it left over that little bit of dark energy. So that is its own curiosity. Perfect cancellation, pretty easy. Theorists do that, you know, eight times before breakfast. Imperfect cancellation, much harder.

Like all theorists do. Well, let’s add something to my equation and see what happens. I mean, and that’s okay. … I’m being glib about that, but that is precisely what you do. You say, what change? We have this thing that works quite beautifully except it fails here. What is the addition that we need to make that changes very little in the realm that we measured and yet fixes this hard thing? And so you literally just go, da, da, da, okay, what do I need? Plus six or something. And as long as it makes no changes where it would hurt our measurements and fixes the big thing, then that is at least a candidate theory. Now, that doesn’t mean it’s right, but it at least gives you an understanding of what the right answer should look like.

And so that’s the first step, is what should the real answer look like or what is a possible real answer? And then once you kind of know that, then other people can look and say, “Well, let me think about a theory that kind of has the required properties to do what we need it to do.” So it’s a multi-step process, but the first step is how do we tame this problem without coming up with really terrible predictions that we’ve already ruled out? And so that’s what you do. And you know, that is literally a sensible, viable, theoretical thing, because you have to explore cool ideas.

I mean, one of the reasons dark energy is super interesting is it kind of gives us a mechanism by which we can talk about the deep future of the universe. I mean, it’s making— We have observations about the expansion of the universe, but it’s also giving us the mechanism of that, right? So we can talk about any weirdness, any good model we have that, that captures some of the weirdness of dark energy might give us insights about how this thing ends, how the universe- … about the deep future of the universe, right?

Absolutely. As it stands right now, if dark energy is real, and who knows, you know, if it’s real exactly as we’ve measured it, then as the universe gets bigger and bigger, dark energy becomes a bigger and bigger component of the- … energy balance of the universe, and it takes over, and it drives the continued accelerated expansion of the universe. And if dark energy gets lower, you know, for some reason that we don’t understand, maybe it changes over time, gets smaller. That could change things. If it gets bigger, it could change things-

That is one of the big open questions, whether it’s constant over time or not.
Don Lincoln
Right. And there has been a recent measurement that suggests that dark energy is getting smaller. However, that is a new measurement, not confirmed, blah, blah, blah, blah, blah. Nobody should believe it, but it’s a hint that maybe it’s changing, which is kind of cool in itself because the current bias until recently is that dark energy is constant. Now, I wanna be super careful because it’s misleading. People say dark energy is constant. Dark energy is a density. Now, that— think about that. You have a certain density, let’s start with that. Then the universe expands.

Don Lincoln
So energy is volume times density. If the universe gets bigger and the density is constant, that means dark energy is increasing. It’s not just increasing as a fraction and overwhelming ordinary matter, but ordinary matter, as the universe expands, its density decreases because it’s constant and the volume gets bigger, the density drops. Dark energy, until recently, is thought to be constant density.

Don Lincoln

… is increasing. Interesting.
Don Lincoln
And so that’s a weirdness, and that then ties into the nature of space. Why does that tie into the nature of space? Well, because if dark energy is a field in space, if you increase the volume, you would think the energy density would drop. But if space is increasing and space is quantized, and I don’t know if it is, then maybe what’s happening is space isn’t stretching, but like little space particles are appearing as the space, you know, there’s like bubbles of space appearing, and each bubble contains a certain amount of dark energy. And so therefore, that would give you a sense that dark energy is a property of space rather than a field in space. But that’s all very hand-wavy guess-worky stuff.

So if you had to bet all your money, is dark energy like a real physical—what does that even mean?—thing that exists, versus is this just an, a renaming of the cosmological constant?

Unfortunately, I think it’s both. I mean well, I mean- It is; it’s describing a reality, but it’s also maybe telling us something about space.

Yeah. It’s, I mean, that’s kind of what it looks like. Given that it seems to be constant density, that seems to me– Now, this is not something anybody should believe. Please, nobody believe this. But it seems to me that this is leaning towards the idea that, A, it’s a property of space, B, space is quantized, C, as space is expanding, little quanta of space are appearing, and D, each one of those quanta has a certain amount of energy associated with it, and that would kind of explain the constant density. Now, please, that’s not– Anybody should– Nobody accepts that. This is just nonsense.

Don Lincoln
Well, they’d be quanta of space. I mean, the idea is, you know, you look at a sand dune and it looks smooth and continuous, but you can see individual grains of sand, right? And so what this is saying is as this dune expands, new grains of sand are appearing, and each one of them is a quantum of space.

I mean, people have been talking about quantum entanglement of gravity. In standard quantum mechanics, a particle can be in two places at the same time. All right? So now you have two particles. So this particle can be in two places in the same time. This particle be, be two places at the same time, and you put them near one another. Well, if they’re close to each other, there’s a certain gravitational force. If they’re far apart, there are certain… And if they, one is close and one is far, you have another one. You can calculate the effects of gravity having to do with quantum entangled particles being in two places.

And people are talking about doing this and trying to see if in doing such a measurement, they might be able to definitively determine whether gravity is a quantum phenomenon or a continuous phenomenon.
And people are talking about doing this and trying to see if in doing such a measurement, they might be able to definitively determine whether gravity is a quantum phenomenon or a continuous phenomenon.
Don Lincoln
And that is potentially a measurement that could be done soon-ish because the technologies inherent in all of this recent work on quantum mechanics is allowing people to be able to make instrumentation that might be precise enough to do this measurement. Now, this will not tell us what quantum gravity is. It will not tell us anything, but it will tell us that gravity is quantized. And just knowing that, well, for one thing, it shuts out a whole realm of continuous gravity, and the theoretical community will then turn its attention, forget this stuff, and think over here. Now, that doesn’t tell you that space is quantized, but it tells you that gravity is quantized if it bears out. So and if gravity is quantized, then people will start thinking more about space being quantized.

Don Lincoln
All right? So first thing, and the most important thing ’cause I’m an experimentalist, by God, the first thing is why do we believe there’s dark matter? And the reason is that astronomical measurements do not agree with predictions by Newtonian or relativity theory. Galaxies spin too fast, clusters of galaxies move too quickly, and the distortion of very distant galaxies due to the gravitational field of nearer galaxies disagrees with the prediction from what we see from the observed matter. So there are three very distinct reasons why we are predicting that, that something is wrong in our understanding of either the laws of physics or the matter budget of the universe. The easiest one to talk about is the spinning galaxies.

Don Lincoln
Now, this is– what I’m saying is not unique to spinning galaxies, just easiest to talk about. So galaxies are observed to spin more quickly than they should if we add up the gravity we see. By all rights, galaxies spinning that fast should blow themselves apart, and they don’t. So what can be the answer? Well, you have the force required for a star to orbit to move in a circle, and you have the force due to gravity, and they’re connected by an equal sign, and the prediction is wrong. So either the force due to gravity is wrong, the force needed to move in a circle is wrong, or the equal sign is wrong. I mean, this is really simple. One of those things is wrong.

Don Lincoln
So one possibility is simply that Newton’s law of gravity, mass times the mass over R squared times a constant, that’s just wrong. Another possibility is Newton’s F equals ma that we are taught in introductory physics is wrong. Both of those are eminently possible. Over here, maybe we don’t understand gravity, or maybe there’s more mass than we can see. So these, you know, I mean, it’s nice that you can look at this really simply and come up with a list, you know, a cookbook of things we can test. And so we’ve done that. We’ve gone and said, “What are the possibilities?” Well, the most obvious possibility is that there is more mass than we can see. There’s black holes, there’s hydrogen gas that we can’t see, whatever. There’s something out there.

Don Lincoln
So that was the first thing. So you go and you look, and there’s no hydrogen gas because we can see that with radio waves. That’s not it. In the ’90s, we went looking for black holes, rogue planets, things like that. Those exist, but not enough of them.

Don Lincoln
That’s not it. And so now we’re left with there’s some sort of matter that we can’t see, or we don’t understand gravity, or we don’t understand inertia. Now, I personally, if you asked me this, oh, I don’t know, 25 years ago, I would’ve said the most likely answer is that we don’t understand inertia or gravity. You know, I– if 20 years ago, 25 years ago, that’s what I would’ve said, no problem. However, there have been a couple of observations that have caused me to change my thinking, and I think that dark matter is more likely. One of them is called the Bullet Cluster. So the Bullet Cluster, there are two large clusters of galaxies. In these large clusters of galaxies, well, any galaxy consists of a couple of components.

Don Lincoln
There are the galaxies themselves, there is the hydrogen gas that surrounds the galaxies, and maybe there is dark matter. And if dark matter is real or dark matter is not real, you will get different answers if those two galaxies pass through one another. The galaxies themselves should pass through one another basically not interacting, but the big thing is the gas clouds. So if there’s big clouds of gas, as the galaxies pass through one another, the clouds should interact, and the gas clouds should stop in the middle and be really, really hot.

So if there’s big clouds of gas, as the galaxies pass through one another, the clouds should interact, and the gas clouds should stop in the middle and be really, really hot.
Don Lincoln
So then you would see, if there were no dark matter, you would see a cluster of galaxies, cluster of galaxies, a big gas cloud in the middle, and because the big gas cloud in the middle is much more massive than the galaxies themselves, you would expect to see distortions that we call dark matter distortions in the middle. If, however, dark matter is real, the galaxies pass through one another, the cloud stops, dark matter doesn’t interact with the cloud, so it passes through. In that case, you would expect to see the distortions where the galaxies are.

In that case, you would expect to see the distortions where the galaxies are.
Don Lincoln
And that’s what we see. So that is a strong evidence in my mind. The Bullet Cluster is strong evidence that dark matter is a real thing. And there is another example which is much more recent (the Bullet Cluster was a while ago) called the Dragonfly galaxies. There’s Dragonfly 2 and Dragonfly 4. These are galaxies that rotate exactly according to Newton’s laws.

Don Lincoln
And so the fact that they rotate exactly according to Newton’s laws says that whatever’s causing galaxies to rotate too fast is not a property of matter. But if you had a galaxy where there was no dark matter, for whatever reason it got stripped off or something, this is one of those lovely ironies that the existence of a galaxy with no dark matter is very strong evidence that dark matter is real because you can take the dark matter out. So the DF2 and DF4 also suggests to me that dark matter is real.

Don Lincoln
So now, while it remains possible that we need to modify the laws of inertia or we need to modify the laws of gravity, those are possible still. In my opinion, and now this is Don’s opinion, but it’s probably the opinion of most of the scientific community, dark matter is likely a real thing.

Don Lincoln
Now, that’s great. I’ve taken you all the way to dark matter. So now you’re gonna ask me, you’re gonna say, “Don, what is dark matter?” I’m gonna go, “I don’t know.” But I know what it isn’t. Okay? I know that it is not black holes. I know that it is not rogue planets. I know that we’ve done the measurements. We’ve looked across nearly every mass range for compact objects and ruled them out. So if dark matter is real, it can’t be made of those. So then you’re left with the idea that dark matter is a particle, and that’s what we’ve thought about. The name for the dark matter particle that we’ve called for a long time is a WIMP, for a weakly interacting massive particle, and we have spent the last, God, 30 years looking for them in the various ways.

There are three ways that we might see dark matter, the direct way, which says that dark matter exists literally everywhere in this room, in our laboratory, and the dark matter is passing through the Earth like a wind, and we put up detectors trying to see those. We have done that, and we’ve seen nothing.

So we need another form, and we have seen zero evidence of this wind of dark matter through the Earth. Another possibility is you look where you think dark matter might be concentrated at the center of galaxies, and if dark matter exists and there’s antimatter dark matter, maybe they annihilate and make photons. And so we look for gamma rays and various other signatures of annihilating dark matter, and there are always constantly announcements of, “Oh, we saw it. Oh, we didn’t. Oh, it…” You know, the problem is that way of looking for dark matter is hard because there are other ways of making, for instance, gamma rays like neutron stars and stuff, and you really need to understand the details of galaxies really, really well to believe that.

And then the final option is what I do, where we smash particles together at high energy. We try to make dark matter particles. If you make dark matter particles, because they don’t interact except via gravity, they escape with your detector. So what you’re seeing, what you hope to see, is an event where you collide particles, a dark matter particle escapes, and you don’t see it, but the recoil you see on the other side because momentum is conserved. So you see a blob of energy on this side, nothing on the other side. Maybe that’s dark matter, and that also happens with neutrinos. So you need to understand everything about neutrinos and calculate how many of those you see and then hope you see more, and then that might be dark matter. Again, that hasn’t worked.

So we’ve ruled out some dark matter particles, but the problem is the range of space of possible mass, if dark matter is of a particulate form, the range of viable dark matter ranges from something like the mass of an asteroid to far lighter than an electron and everywhere in between. And we have looked. We’ve ruled out some little spots in that phase space, but that’s a big range.

Is it really possible to miss a particle the size of an asteroid?

The astronomical searches were not sensitive to that level of dark matter, but, you know, then you would expect that there would be some of those in the solar system. And if they’re what we think, like asteroids or something, then we’d heat them up, and we’d eventually see them. But if they’re really, like, truly dark matter, doesn’t interact with matter, which means they wouldn’t absorb energy from the sun, so they’d be really dark. I don’t know. Maybe they’re out there. But the only way we have searched for them was a thing called microlensing. So if a massive object, you have a distant star, and a massive object passes between that star and your eye, that star will momentarily brighten.

And so you just look for these, what they call microlensing events, and you count them, and you see some. And we did see some. You know, black holes pass in front of stars, and we’ve seen them, but we just haven’t seen enough. And for very low-mass particles like asteroids, they just wouldn’t make enough brightening effect to see. So there’s, like, a minimum sensitivity of brightening and that about a third the mass of a moon, our moon, is about the sensitivity that we had. So, you know, nobody, I think, really thought that these low-mass guys were likely. What they thought was more likely they were just unseen black holes, which I thought- … you know, I think is completely reasonable.

And then when that got ruled out, I thought, okay, modified gravity or inertia. Well, now the, you know, Bullet Cluster and Dragonfly seem to have ruled that out. So I’m stuck in my head with: dark matter seems to be real, and we don’t know what it is.

And that’s why it’s cool. So if someone out there is, you know, a young person who wants to get into this, understanding dark matter is a big deal. I mean, it’s five times more prevalent. The problem is, as I told you, if the mass is ranging from an asteroid to far lighter than an electron, if you get on an experiment that looks at one little range of mass, maybe you weren’t the lucky guy that measured the right place, you know? And that’s one of the reasons why, as fascinating as I think it is, I’m not doing dark matter experiments because, you know, if you make an experiment that searches one mass range, it’ll be blind to another mass range.

So what you need is you need many groups doing all sorts of radically different experiments, exploring all sorts of parameter space. And with all that said, until you see it, there still is the possibility that maybe we don’t understand gravity or inertia right. You know, you can’t rule that out.

I mean, I don’t know what it is. I think it’s cool. It’s very, very fascinating. That is one thing I really do hope in my lifetime is understood ’cause I’d like to know the answer to that.

Or you have to come up with that really cool theoretical idea that everybody’s overlooked, which is another possibility. And there are people who are really, really religiously hating dark matter, largely because we’ve looked so hard for so many years and the experiments in today’s world are a million times more sensitive than when I was a starting student- … and they still haven’t seen anything. And that’s why people really hate dark matter. I mean, some of them- … because they think we should have seen it by now, but- … you know, I don’t know.

I mean, I’m a sucker for direct observation. Not– Indirect is obviously also really great, but direct, just imagine pointing your telescope in a certain direction and because of some artifact of cosmology being able to directly detect a giant amount of a thing that you could say is dark matter.

We did that in the ’90s with experiments called MACHO, OGLE, and some others. They looked for a black hole that you just can’t see, you know, a black hole you can’t see. It’s perfect. It’s a perfect candidate for dark matter. And if there’s enough of them out there– Now remember, there’s five times- … the number of stars, which means there’s a whole lot of freaking black holes out there. We should have seen them, and we didn’t.

Future of physics
Lex Fridman
What a grand mystery. We’ve covered so many of them. I could talk to you for a thousand more hours, Don. Let me, if I can, ask you about a little bit more of a on the personal side. You have a really inspiring life story. Your folks didn’t go to college. Can you just tell me about your childhood and where you found the love for physics and science, and maybe how you found your journey to become a physicist, given the context of where you came from?

Don Lincoln
Well you know, I grew up a poor kid in the boondocks. Great parents, but not ones that could guide me terribly academically, but very, very nurturing. You know, my mom would laugh that she could stop helping me math after like sixth or seventh grade, you know. But they were supportive. And there were a couple of things that– couple, three things I think that folded into it. One is I was a voracious reader as a kid. I loved science fiction. I would read a book a day. It drove my mother nuts ’cause she would try to be nice. She’d buy me a book, and I’d say, “Thank you,” and the next day it’d be done. You know, it just drove her completely nuts. But anyways, but science fiction is good for fostering imagination, and so that’s precisely what it did.

In addition, and this is where the more serious science came along, there were lovely science communicators that were popular in the 1970s, Isaac Asimov, Carl Sagan, a guy by the name of George Gamow. They wrote books about science aimed at a layperson. You know, as a kid, I surely couldn’t read a textbook and understand it, but I could read and, you know, get a hint of what science was. And on top of that, you know, I was, as most scientists, people who became scientists, irrepressibly curious about everything. And I had sort of a quasi-philosophical mind. I mean, I was interested in things that, questions that have in the past been theological and then philosophical and now are more scientific. Questions about how did the universe come into existence?

Don Lincoln
Why is the universe the way it is? Why are the laws of the universe what we see them to be? How will the universe– Was it created? How will it be destroyed? These are, you know, big questions that have bothered humanity for, well, thousands of years. And so, you know, I did. You, you said I had philosophy and religion minors in college, and I did ’cause I was curious about that. I was hoping that learning that history might help me understand these questions. And it was in college where I came to realize that the answers that I was searching for were not to be found in those directions, but I still learned about how those questions have been asked in the past. And so I became a scientist, and the only question was, was I going to be a cosmologist/astrophysicist-

Don Lincoln
… or a particle physicist? And when I had to make that decision. It was the mid-’80s, and at the time, there were a lot fewer cosmology measurements. There was an awful lot of thinking about the universe and not enough measuring. Whereas with particle physics, by God, you could do experiments. And so the– what attracted me was the ability to actually get an answer and not just mull over what an answer might be. And so I became a particle physicist. It was difficult without having, you know, family mentors or anything like that, but, but, you know, I managed.

And that actually is why, well, I’m here and why I have spent a fair bit of my time writing books and so forth, because I figure that there has to be some other kid out there in Iowa or Kansas, Montana, somewhere out in some little town without a lot of access to the kinds of thing that people, you know, who have highly educated parents do. And I’m hoping that, you know, some of them will have read some of the things I’ve written and will find their own path forward, because I found it very rewarding over the years. And you know, I’ve been doing this long enough that I’m, I’m sure this is true. I’ve had kids come up to me at the lab and say, “Hey, I’m a summer intern because I saw your video or read your book,” or, you know, whatever.

Don Lincoln
So I know that at least I’ve made a small impact. I mean, I always would like to do more, and, you know, I appreciate the opportunity that your audience affords me ’cause I, I think it’s important to talk about these things. These are really cool, fascinating questions. They are unanswered, and they are just waiting for youngsters to come and spend some time thinking about them, ’cause one of your viewers might be one of the people who answer these questions that have stymied very smart people for decades.

And we should also say that you’re a legit scientist. So what– we’ll mention Sean Carroll, who’s a legit scientist, legit physicist, but is also a good science communicator. Anyway, I did wanna mention, I don’t know if this is true, but I, I kind of heard you talk about this, that when you first showed up to Fermilab, you were, like, working crazy hours, working extremely hard- … eight AM to midnight.

First of all, I love that. Can you speak to what drove you and maybe the value of hard work in those contexts, in your, in the early career when you discover a thing you’re passionate about?

Well, yeah. I mean, obviously being smart, you know, if you’re Einstein, then maybe you can slack, I guess. Although even he didn’t do that, but I’m not Einstein. But the fact is, when I was young, and I was unencumbered, no family, no kids or something, I couldn’t imagine anything I wanted to do more. I mean, some people, they wanna go out to the club. They wanna, I don’t know, play soccer or something. But I wanted to make measurements, and I wanted to understand and learn, and that was fantastic. And so as a graduate student, and this isn’t for everybody, but I worked outrageously.

Don Lincoln
I would, from Monday through Saturday, I would be at the lab voluntarily because I wanted to be from eight AM to midnight, and on Sunday, I would work from eight until about five, and that’s because from five to midnight, I had to wash clothes and buy groceries and things like that. And I loved it, you know. And I still love it. I can’t do that anymore. But, but that’s simply because I have other obligations. But had I been rich, I would’ve done the same thing.

Don Lincoln
You know, it’s something I truly, truly loved. And the– I mean, there is absolutely nothing more fascinating to me than having a hard problem and figuring it out. And that, you know, that work ethic– Well, there’s a couple of things that separate smart people from no-kidding scientists, ’cause all scientists are smart. But the thing that separates, that many scientists have is, A, a drive and a real grit. For me and for so many scientists that I know, trying to measure something and having it not work just kinda ticks me off, and I am not going to let the universe in my lab or whatever beat me. And, you know, some people… they, you know, if the thing breaks, it’s like, “Oh, man, that didn’t work.” And a lot of people, “Well, I’m gonna go home.

Don Lincoln
I’m fed up.” Nah, it would just kinda make me mad, and I’d put more effort into it. And, you know, not every– I mean, okay, I was crazy. I worked long hours. But, but I think- … the people who are really good at this will do maybe not that much, you know. Some people have to have a better life than that. But, but a lot, because it, it’s just you can’t imagine not knowing the answer.

Don Lincoln
And that if– When, when you see that as an older guy, you don’t– maybe not to that degree, but when you see that kinda drive, that intensity of trying to get the answers, you know that person’s a winner. And, and so if, you know, some student out there, if it doesn’t, you know, bring you joy, as uh, what’s her name? The Japanese girl says, “If it doesn’t bring you joy, then it might not be for you.” And then you could be a person who reads about it and, you know, is involved. But if you wanna be a real scientist, it has to be just part of what you are here.

Well, I’m glad there’s people like you at a place I admire, like Fermilab, one of the many places in the United States and the world that is carrying the beacon of great science and great engineering forward.

The important thing is, is your code good? We care about excellent code. We don’t care who you are. Like maybe you’re a dog. I don’t care, right? I don’t care where you come from. I need to look at your code. Oh, yeah, but I’m an engineer at this very large company in Italy, in Germany, in the US. We don’t care. We care about the quality of your code because this is what defines our community, which means that we have a lot of people who contribute who are from very different backgrounds and very introverts. Sure. But that’s okay, right?

FFmpeg is probably one of the biggest CPU users in the world. Everything we’ve just said in the past couple of minutes, every sentence is someone’s lifetime’s work. There are books about every sentence. So the level of complexity in many cases is inordinate.

Introduction
Lex Fridman
The following is a conversation all about FFmpeg and VLC with Jean-Baptiste Kempf and Kieran Kunhya. FFmpeg is an open source software system that is the invisible backbone behind YouTube, Netflix, Chrome, VLC, Discord, and basically every platform that touches video or audio on the internet. It can decode, encode, transcode, stream, and play almost any video or audio format ever created. To me, it is one of the most incredible software systems ever developed, and it’s all done by volunteers. VLC is also a legendary piece of software. It is an open source media player that plays basically anything you throw at it, any format, any platform, no ads, no tracking.

It has been downloaded over six billion times, and again, for me, it has been one of my favorite pieces of software ever, with the most legendary logo, which I, of course, had to honor in this conversation by wearing the VLC traffic cone hat the whole time. So again, above all else, thank you to the incredible volunteer engineers who put their heart and soul into this code that has been used and loved by billions of people. Thank you. And about the two great engineers and human beings I’m talking to in this episode, Jean-Baptiste is the president of VideoLAN and is a key figure behind VLC and FFmpeg.

Kieran is a longtime codec engineer, FFmpeg contributor, and the man behind the now infamous FFmpeg account on Twitter/X that I recommend everybody follow for the memes and for the unapologetic celebration of open source and great low-level software engineering. Let me also say that it’s inspiring and humbling that so much of modern civilization rests on software built by people who are not chasing fame or money, but are obsessed with the craft of engineering. We live in a world where billions of people consume video every day without ever thinking about the invisible machinery underneath it. But that machinery matters. Open source infrastructure matters.

It is one of the great examples of human beings quietly collaborating across borders to build something useful, durable, and elegant for the rest of us. And so this conversation is not just about codecs and media pipelines. It is also about the deeper spirit of engineering and generosity that makes projects like FFmpeg possible. Again, I can never say it enough. Thank you. This is the Lex Fridman Podcast.

Basically, it’s, you know, those type of capture cards where you can put a Peritel in or- … or RCA, and you put that, and actually VLC can play those type of cards, and there is a module which allows to control directly some of those VCR camcorders. We support DVD-Audio lately, right? We spent the summer working on DVD-Audio support, and like there is no, no one’s making any DVD-Audio support. There are custom encryption schemes.

How video playback works
Lex Fridman
So the thing that we’re talking about is everything around video codecs, video encoding, video decoding, video streaming, video player client that I’m wearing on my head, the entire ecosystem enabling free media. We’ll talk about FFmpeg, we’ll talk about VideoLAN, VLC and all the other incredible video technology that is used probably by billions of people. So JB, you’re the lead developer behind the legendary VLC player. Kieran, amongst many other things, you’re lead developer behind the legendary FFmpeg handle on Twitter. And both of you have spicy opinions I would say. So today we wanna talk about FFmpeg and VLC.

Lex Fridman
For context for people who are not aware—and I’m sure basically everybody listening to this have used these two technologies probably regularly without knowing it. So FFmpeg underlies basically most video on the internet including YouTube, Netflix, Chrome, Firefox, of course VLC and countless other video platforms. It is estimated that over 90% of video processing workflows online and offline involve FFmpeg. VLC has been downloaded at least 6.5 billion times. But likely that number, ’cause it’s impossible to really count the number, is much higher than that. Virtually any operating system supports virtually any media format. The limitation being it can’t open pancakes. So can we just lay out some of the basics to, to help people understand what’s involved in all of this?

Lex Fridman
So when we press play on a video player like VLC, what happens? How does it go from the file or the stream to the pixels on the screen and the sound on the speaker? What are the big stages to be aware of?
So when we press play on a video player like VLC, what happens? How does it go from the file or the stream to the pixels on the screen and the sound on the speaker? What are the big stages to be aware of?
Jean-Baptiste Kempf
So there are several stages, right? The first stage is to get from an address, right, which is the type of URL, to give you a byte of streams, right? So this would be, for example, HTTP, file, DVD, right? You give the path to the media, and it gives you a stream of data.

Kieran Kunhya
The stream needs to be cut up by what’s known as the container, the demultiplexer or demux. We’ll try and keep the jargon light throughout this, but it needs to go and start demarcating video and audio frames. So it just gets data from the operating system blocks at a time and needs to start cutting these frames up into compressed data. It then needs to start doing simple parsing of the video frames-

… mainly to figure out whether that codec is GPU decodable or needs to fall back to software. We’re very sort of used to assuming the GPU will play all of these things. There’ll be hardware acceleration. I think it’s up to forty-five percent of files are not GPU decodable. So these need to be probed. They need to be detected. There can be variants of a given codec, some of which are decodable on the GPU. Different vendors of GPU might have different capabilities, so those need to be detected. So if, if it’s GPU capable, you pass it through to the GPU black box. So now if there’s a software fallback, that means in the beginning is, is to first do deentropy coding, so removing the mathematical coding of the bit stream.

Kieran Kunhya
So this uses capabilities such as Huffman coding or arithmetic coding to actually decompress the mathematical layer of the bit stream. We then need to start reading the syntax elements for intra prediction. So intra prediction are like still images of the video, so your I-frames. So this works and operates in the spatial domain. So you do your intra prediction in spatial domain. You have a residual because your prediction isn’t quite matching that of reality. So you’ve made a prediction, but then there’s a little bit left, and that’s what’s known as the residual. This is stored in the frequency domain, and these are quantized to decompact their space. We then need to do the inverse transform to bring them back to the spatial domain and apply these residuals.

So a lot of the process of the decoding is this thing is compressed. And you have to predict the highest quality thing that’s supposed to go there. I-frame- … is the best representation you have spatially.

Yes.
Yes.

And then there’s a lot of temporal compression that can happen depending on the codec, and then you’re predicting. You’re predicting what the reality that was captured in this rawest form.

Jean-Baptiste Kempf
Yeah, because what people don’t realize is that the compression on video and audio is one hundred times, right? Like, people don’t realize how compressed we do, right? For audio, you move, you compress by, when you go from normal audio to MP3, you compress by ten times, right? When you move to video, you need one hundred times, two hundred times, right? So you need to remove all the details, but that you don’t care about because all the compressions that we do, and that’s very important, people forget about that, is to be viewed by humans, right?

Jean-Baptiste Kempf
So all the codecs, either for audio, mimic basically how your ear works, right? And a lot of things about, like, the response on the ear and same for your eyes, right? And so, for example, on video, we don’t work on RGB, right? Everyone expect to work in RGB. We don’t, right? We move to YUV, which is basically one is luminance, brightness, and the other are colors. And this matches your eyes, where inside your eyes you have the cones and the rods, right? With some of them look on brightness and more on the other on colors, right? So we need to compress a lot, and so we need to degrade. But in order to degrade, we need to match the human perception, and this is why it’s so difficult.

Jean-Baptiste Kempf
And then we need to use the maximum power, mathematical power, very complex technologies. We move to the frequency domain, as Kieran said. We do a ton of dequantizing in order to get the best compression, but it still looks good.

Jean-Baptiste Kempf
That is correct. And this is very important, right? Compression is not like a ZIP, right? A ZIP, you have data in, you get data out, right? And you try with all the ZIP compression to arrive with the limit. Here we are degrading the signal, right? And so we need to degrade both the audio and the video signal in the best way possible. And we can do that, but it involves, first, a lot of theoretical knowledge about how the eye works, but a lot of mathematical change, a lot of mathematical tricks, right? For example, when you move to RGB and you go to YUV, for example, what we do very often is that we scale down the resolution of the color compared to the brightness.

Jean-Baptiste Kempf
And most of the time, and just this without compression, it divides the size by two, but most people don’t see it, right? And so on and so on, right? And then you go to very complex mathematical change. So of course Fourier transforms, which de facto are not Fourier transforms, they are like discrete cosine transforms, but that’s the same idea. So frequency domain we split the video by blocks, right? So that’s why when it’s wrongly decoded, you see those blocks, and badly encoded, you see those blocks, and so on, to arrive to compression states that are insanely high, right? And each generation of the codec is like thirty percent less- … for the same quality, right? And this requires amount of power, of computational power, that are huge.

Kieran Kunhya
No, no, but you should, you should elaborate. It’s thirty percent better, but an order of magnitude, perhaps, perhaps even two orders of magnitude more compression power. That’s the big difference.

Kieran Kunhya
Sorry, CPU power to achieve that level of compression.
Sorry, CPU power to achieve that level of compression.
Lex Fridman
Oh, yeah. So and you have to be able to leverage the CPU and sometimes GPU, like you mentioned. And then we should mention that a lot of this programming is done at the lowest possible- … stack, whether it’s C and of course, as, as the legendary- … Twitter handle re-emphasizes over and over, a lot of assembly.

Jean-Baptiste Kempf
So what happens globally is that you have an address, right? Which gives you with the operating system, a stream of bytes, a stream of data, right? And this is the first step. And the second step arises with demuxing, where you’re going to separate audio, video, subtitle in type of different tracks. And then on each of those tracks, you’re going to decompress them, decode them, either audio with an audio codec, video to video codec, and subtitle to subtitle codec. And once you’ve decompressed those type of things, you have raw images, raw, and then you’re going to talk with your graphic card in your screen and display that. And same for the audio, you’re going to talk to your audio card, which then is going to go in analog to your audio speakers.

And everything we’ve just said in the past couple of minutes, every sentence is someone’s lifetime’s work. There are books about- … every sentence. So the level of complexity in many cases is inordinate. You know, it’s… Every sentence has thousands of people working on this- … in industry as a whole, books written about it. So there’s a lot of detail, there’s a lot of subtleties, there’s a lot of both academic and practical realities, both of which matter.

Video codecs and containers
Lex Fridman
We mentioned codecs, but I don’t think you mentioned containers. So what are the actual containers for some of the stuff we’re talking about? So people are familiar with MP4, MOV, MKV. So anyway, what are containers versus the thing that goes inside?

So the container is what we call also the muxer, right? When I say demuxing, it means decontainerizing, right? So actually, if you look, mux means multiplexer and demultiplexer, right? Mux and demux are those. And same, a codec is actually coder, decoder, right? And so containers are this collection of multiple tracks, right? So it’s a, what normal people call the file format, but it’s a bit more subtle than that. But the most known one, of course, is MP4, but when I started, it was AVI, right?

And there are so many others.

So, I mean, there’s a, it’s a pretty common thing, and maybe it’ll even happen in this conversation, that people confuse container and the codec, right? So confuse MP4 and H.264, for example. Is that a horrible violation?

Jean-Baptiste Kempf
No, it’s not, because technically the name of H.264 is MPEG-4 Part 10. Because MPEG-4 is actually a meta specification which has several things in it, right? There is the Part 2. So there is, like, audio codecs, right? AAC de facto is MP4 audio- … something. There is actually several video codecs, right, inside the MPEG-4 specification. One of them is MPEG-4 Part 10, called also AVC, called also H.264. Right? So it’s completely the fault of the industry to make things difficult to understand. So that’s very difficult so that people then don’t understand why sometimes you talk about MPEG-4 Part 10, where you mean H.264, and why it’s not MP4.

So you can technically shove in all kinds of different codecs inside containers and horribly so.

But broadly speaking, though, MP4 is understood to generally be H.264 plus AAC audio. 99% of the time that’s that, and that, the, the rest are de minimis, the small effects, you know, edge effects really compared to that. So it’s not the end of the world. There are people who do get annoyed by that. But also in reality, something like VLC, just to point out, the file may say .MP4, but it may be something completely different, and that’s one of the challenges both FFmpeg and VLC have is the real world is a completely different place to a three-letter file format.

Jean-Baptiste Kempf
And this is very important to say, right? Like, for example, in VLC and in FFmpeg, we discard the file format, right? We look into the file to understand what’s in it because so many people, like, they say, “Oh, it’s a video, it must be MP4,” but technically it’s an MOV or maybe it’s a MKV, right? So we analyze in real time everything that we have, and we don’t trust- … the format.

So what information does the fact that it’s .MP4 give you?
So what information does the fact that it’s .MP4 give you?
Jean-Baptiste Kempf
It helps, right? It gives you a hint, right? Just like, oh, it’s finished by .MP4. I will start first by opening, probing it with the MP4 container demuxer to see, well, it should be that. But I don’t trust it, and if I’m lost, I say, “Okay, maybe I’m going to try it.” So it bumps the priority of the module.

So how do you get to—just to take a bit of a tangent there. You know, the dumb thing is if you try the MP4, but it turns out it’s a different codec than you would have expected, most players just break there. And so how do you not break? There’s just philosophically, I’m sure there’s a bunch of stumbling blocks along the way where it’s easy to just break and stop, freak out. That’s it. How does VLC not?

This is why VLC is popular. But the reason is because actually VLC was, is just a client of a streaming solution called VideoLAN from a very long time ago, from the late ’90s. And when you’re playing video which are on UDP, right, in network, they might be damaged, right? So you don’t trust your inputs, and this is very important into the security is that you don’t trust your inputs. So everything in VLC is prepared to work with broken files. And it’s a philosophical idea from the beginning, and everything is engineered into that. And it’s a culture, right? And so, for example… And VLC became very popular on that because a long time ago when people were pirating content which they do a lot less today, um-

No, of course not. Um- … the metadata to play some files like AVI is at, at the end of the file, right? And when you’re downloading, you don’t have that, right? So VLC was just like, “Hey, this file is broken, but I’m still going to try to interpret it,” and this was very useful.

We hinted at the awesomeness of the various different stages. We hinted at the awesomeness of codecs, the depth and the richness and the complexity of everything involved there. What— Let’s try to define what is a video codec? What’s involved there? What does it mean to compress something? You already started to hint at it— … but can, can we elaborate a little bit more?

So there’s a huge amount of redundancy in any video, both spatial and temporal, and the point of any video codec is to remove this redundant data, use mathematical properties as part of this reduction process. So more often than not, using several orders of magnitude more compute to compress because that’s more costly, both financially and in CPU resources— … versus the decompression. So it’s asymmetric in that respect. Often the case because compression is done once, but there could be lots of viewers of another file.

Kieran Kunhya
So to take that information and compress it by 100x, 200x, removing redundant information and using mathematical properties to make that small, but also have properties such as error resilience. So as JB suggested, VLC in the beginning was used to play UDP network feeds, and UDP network feeds lose packets. And so some of the design goals of a codec is also to be recoverable. You need to actually be able to join a stream. It’s not necessarily a file. You need to join, get on the decoding process, and start decoding.

And to give a more image to people who are not familiar, right? Like, when you’re going to see any type of movie, right? You’re going to see the camera is going to pan, right, and travel. And you realize that, for example, all the background is the same for like a minute, right? Or— … thirty seconds, right? So you can reuse the cloud that you see on the background, you can reuse that from a frame to another, right? And so it gets the more, the more memory you have, the more power, the more comparisons you can make, right? And so the more compressed you can be. And most of the modern codecs are basically doing that.

So just to make it even more explicit. So what is video? Video is a bunch of pixels off an RGB. You have three values, and you have a grid of pixels, and you have, let’s say, twenty-four or thirty or sixty frames a second, and you just have all these pixels repeating and showing different stuff- … thirty times a second. And so the question, the philosophical, the technical question is, how can I compress all of that, store all of that at 100x?

Jean-Baptiste Kempf
So for example, you have a picture of a cloud, right? And from the next frame, it’s still going to be the same cloud, so it’s redundant. You could just put it once and not do it, right? Or you have a black background behind me, for example. The black is the same on the whole picture, right? So you can say, “Well, you know, in this picture, take the pixels that you have on the top left and the one on the top right. I’m not going to give the value. I’m just going to tell you it’s the same at the top left.” And then you can say for frame one, reuse something from the previous frame or the previous, previous frame, and so on and so on, right? So you could… Basically, it’s unlimited, but then it’s limited in terms of memory or in terms of compute power.

And then when you’re showing it, you have to do the decompress of all of that. So is it the codec, has the encoding and the decoding is a coupled process that you’re developing?
And then when you’re showing it, you have to do the decompress of all of that. So is it the codec, has the encoding and the decoding is a coupled process that you’re developing?
Jean-Baptiste Kempf
Yes, exactly, right. And those are two different trade-offs, right? Are you going to compress more? But then it might be more difficult to decode. Are you going to make it a codec that is more complex to encode and easier to decode? Are you going to make a codec that is easier to encode because you need to be fast, but then the client side, the player is going to spend more time? That’s why you have so many different types of codecs, is that it’s not always easy. And to make it even more complex, modern codecs like AV1, AV2, or VVC are actually not codecs. They are a collection of tools, right? There are multiple tools, multiple codecs in the same codec to, depending on the image, get the more compression.

Kieran Kunhya
So just to elaborate, codecs like AV1, VVC have a much wide, have a wide audience. It could be a screen share content, it could be video, it could be animation. All of these require different coding tools. So what happens these days is a collection of tools are put in and called AV1 and called AV2, called VVC to allow for different use cases. So you may be on Zoom and sharing your PowerPoint, and then you need to show the audience a video. That codec needs to start changing its tool set depending on the content to compress in a different way.

Jean-Baptiste Kempf
FFmpeg is basically the low-level libraries for codec, so compressions and decompression, muxers and demuxers, and filters. It’s– The core is this, and then you have a several tool which allow you to create a type of pipeline to process any type of video files. And it’s used as a library absolutely inside everything from VLC to Chrome to your smart TVs, to basically any video that you see online you usually use FFmpeg. And FFmpeg in it has all those type of tools, and sometimes depend on other libraries like x264, libvpx, and others, right? So, so it’s really now the de facto tool to process images.

From a philosophical level, I think it’s incredible that your home videos, your, your grandmother’s home videos and trillion-dollar corporations effectively are on a level playing field using the same technology stack. It’s– it wouldn’t be a surprise, you know, these big companies just have three thousand-line FFmpeg commands. There are some that use the API, but there are some that just have long command lines.

So yeah, there’s a bunch of tools, like literally command line tool, FFmpeg, of course, FFprobe. There’s libraries, libavcodec, libavformat, libavfilter. But the FFmpeg on the command line- … is, like, legendary because you can cut– Like, there’s so many parameters. You can customize everything to hell.

But you can– We’ve seen thousands of characters, and we’ve seen also, like, people doing programming generation of command lines to make FFmpeg. There is a ton of people who are using AI to generate command lines for FFmpeg because you have no idea what it is. But you can specify so many filters, right on command line, right? So FFmpeg is this collection of toolbox for multimedia processing that everyone, everyone uses. And everyone that is watching your videos are also using, right? You’re on YouTube. Well, it’s FFmpeg on the client side. Well, the server side, on the server side. The client side is probably Chrome. Well, you’re using FFmpeg also.

I mean, there’s like so many, just to give people an idea, like I use FFmpeg a lot on everything. Just trivial stuff like take a video, add an intro video and an outro video, and fade one into the other like what is it called? Dip to black, like where it dips and then shows the next video and does the same thing with audio. There’s like a cross dissolve of the audio. It quiets the audio and makes it loud again. And then there’s a bunch of stuff like showing the captions on screen card, like baking the captions in. You can customize the font. You can do all kinds of layering of audio and video. There’s a million things and of course, all of that works like magically with basically any codec. Like anything you can shove in on the audio and the video side, it works.

And the vision behind, and the same for VLC and FFmpeg, is that we make everything that is very complex easy to use for the normal people, for everyone. Right? Our goal is to make something that is insanely complex technically and make it easy to use, right? And people, they use VLC, they drop a file. They don’t realize how complex the file is, but they play it. Or people put any type of thing inside FFmpeg with complex filters, and it just works like magically, right? And people- And this is our mission, right? Make very complex things.

We wouldn’t be here and you wouldn’t be here if this required, you know, a traditional television studio setup. It’s tools like FFmpeg that democratize this.

You know, FFmpeg was a big player in that because it democratized this technology that was once in the nineties, for example, you needed equipment that cost hundreds of thousands of dollars to do compression. It was the size of a car, and now everybody has that at almost an exact level playing field, and that’s something that’s so remarkable.

But it’s like you realize also everything moved from text to images and images to video, right? Look at social networks. Video is everywhere. It’s the most powerful medium there is, right? And when you see shorts and Reels and TikTok, right? It’s amazingly powerful to give… Video is amazing for that, right? But the complexity is important.

Lex Fridman
This is what people don’t realize. I mean, this is really—it gave power to the individual all across the world. That’s real freedom. And I think, I can’t believe it, but we still haven’t mentioned the actual obvious thing for people who are not familiar, which it’s open source, and there’s an open source community of users and developers behind it. So it’s really a movement. So, like, we’ll talk in a bunch of different ways about the community behind it. But can you speak to the open source element? So when we say what is FFmpeg, it’s an open source project.

Jean-Baptiste Kempf
Yeah. So FFmpeg, VLC, x264, VideoLAN, everything we do is fully open source. And for the people who don’t understand how open source is, my usual analogy is about a chocolate cheesecake, right? Usually for you, when you want to buy your cheesecake, you go to a bakery, they give you the cheesecake. The other one way of having a cheesecake is have your grandma give you a recipe of how to make that. When we do open source, we give you the chocolate cake, and we give you the recipe to actually remake the same cake, but at the same time tell you how to build the oven and also how you’re allowed to modify the recipe and resell it to someone else.

Jean-Baptiste Kempf
And this is because software is just a very long recipe of small instructions. Computers are not very clever. They go very, very fast. So a normal program has tens of billions of instructions instead of the tens when you have your chocolate recipe. So a lot of the software industry was about selling software where you just have the final cheesecake. In open source, we give you everything, and that managed to get a lot of people to work together, right? Because then you decide that you’re going to make the best program, the best recipe for video, and you create communities. In FFmpeg, since the beginning of FFmpeg, probably two thousand to three thousand-

Lex Fridman
In the thousands, yeah
In the thousands, yeah
Jean-Baptiste Kempf
… people have contributed from the beginning, right? And then it’s exactly like the Linux kernel, right? The Linux kernel has probably ten thousand people contributing everywhere, and they get together, well, mostly online, right? So they virtually get together to create the best tool for something. And on FFmpeg and VLC, it’s just like, well, this codec doesn’t work, so I’m going to work on the codec, and I’m going to add the support for this file inside FFmpeg, so it will be beneficial to everyone. Because again, we work for the greater good. We work for everyone, and that is what open source is.

Jean-Baptiste Kempf
Well, yes— … people do. People do, right? There were a lot of problems with mostly cloud providers who are basically running some open source tools in the cloud and just give you the API to access to that. And there was a lot of databases like Mongo or Elastic who changed their license in order to avoid those types of scenarios.

Kieran Kunhya
This is a question we get a lot in FFmpeg is, “Why don’t you do that?” And you can’t. We have, we have thousands of contributors, some of whom aren’t even alive anymore. It would need all of their agreement to do that, and JB will go maybe a bit later and talk about how challenging that process was in VLC to do the re-licensing.

The license is a social contract in terms of Rousseau de facto of the community. The community does not agree on much besides the license. People go around, discuss around because of the license, and that also allow those license forks, right? Sometimes the community splits, but it’s possible because of the license and to merge back.

And we’ve seen that so many times, right? GCC and EGCS in the past. We have seen, for example, all the web browsers, right? They started as web, like KHTML, which becomes WebKit and then which becomes Blink, right? So open source license is like the core of the community and people are coming from all around the world, very different types of religion, political borders. They work in the same way on a project to solve a specific problem, and the specific problem we’re working on is to make multimedia easy for everyone.

Looking it up on Perplexity here, looking at the different open source licenses. Most major open source licenses fall into two buckets: permissive, very few conditions, and copyleft, share-alike requirements for derivatives. Below is a brief practical summary of the main ones you’ll see in the wild. MIT license, BSD, ISC Apache GNU GPL, GNU AGPL. Where’s LGPL? Yeah, LGPL. Let’s see. There’s the Mo- the Mozilla Public License. There’s Eclipse Public License. It goes on. There’s a lot of variety. I mean, I think the really popular ones are MIT, GPL, LGPL-

Jean-Baptiste Kempf
There are many licenses for many different things. What people don’t understand is that public domain is something that doesn’t exist worldwide, right? So all the open source licensing use the copyright law, right, the international copyright law, in order to give rights on how you use the software or how you modify. It’s de facto a copyright license contract that you give to the end user or to the developer. And so you have like the first ones, which are basically very permissive, MIT, BSD. You give the code and basically you do whatever you want, right? You take it, you want, you modify, you do what you want. And this is popular for JavaScript and the type of BSD operating system.

So some of them, one of the parameters is whether they require attribution, meaning if you use the code, you have to say-
Jean-Baptiste Kempf
Yes. So in those types of permissive licenses, some you need to say if you use it, which is called attribution, and some you don’t. And then there is the other part of license which are copyleft, where you need to give back to the community your modifications and with different strings attached. Some weak copyleft licenses, like the Mozilla Public License, to some which are a bit stronger like a GPL, or even very strong like AGPL. So all of those are different types of licensing that depends on what your goals are and how you want to structure your community, which is why I spoke about social contract, because this is very important to understand. FFmpeg and VLC are mostly GPL or LGPL. The Linux kernel is GPL but Android is Apache.

A ton of JavaScript frameworks that are used are mostly MIT. All the BSD kernels, OpenBSD, NetBSD are of course BSD. And so the… it’s a philosophical change on how you want people to contribute back- … basically.

Lex Fridman
So there’s I think you talked about that you’ve moved at one point from GPL to LGPL on certain parts of the project. What… Can you describe the difference between the two, and what does it take to move to, I guess, a more permissive… So that direction is more permissive. LGPL is more permissive than GPL.

Jean-Baptiste Kempf
Yeah. So you have to realize that you can always go from more permissive to less permissive, right? Because of course, those licenses are basically statements, and so if you restrict, you can always restrict more, right? So in a GPL project, you can take MIT code, but you cannot do the opposite, right? Because they are more constrained to match. Indeed, in fact, I changed the core of LibVLC, which is the engine of VLC- … from GPL to LGPL. And there were two reasons to do that. The first one is that so people can use the VLC engine, LibVLC, into third-party applications. So a lot of applications which are playing video on your phone or on your tablet are actually VLC engine in it- … which is calling FFmpeg in it.

Jean-Baptiste Kempf
So that was one of the ways to create one of the companies I created, which is doing consulting and integration of those types of applications where you integrate VLC into third-party solutions like inside game engines or stuff like that. With GPL, you couldn’t do that because that means you needed to open source everything, and those are for a lot of, like, commercial companies who don’t want that.

So you can create a company with LGPL, you can create a company around it. You can do a commercial thing. You don’t have to open source it. So that’s a big, big leap.

Kieran Kunhya
So you could play video in your game. The problem is I’m a game developer, and I want to play some videos- … and I don’t want to be forced to open source the entire game just to play those videos. So that’s where the, the consulting business, the libVLC LGPL- … allows you to do that. The LGPL, the library GPL as it used to be known, allows you to do that.

And FFmpeg is exactly the same. It force… LGPL forces you to give back what you change on this component, this- … library, which is why it’s library GPL. And so you can use FFmpeg as LGPL into, like, any type of application, even non-open source, but you need to give back the modification you did on FFmpeg. Same on libVLC.

Is it limiting from an open source perspective to go GPL? Because if your library, if your code is GPL, it means you’re basically discouraging companies from building a business- … around it, right? Is that, is that fair to say?

Jean-Baptiste Kempf
It depends on the company, but for the company whose business model requires the application to be closed source, yes, it’s limited. So that’s why, for example, I moved to LGPL. The second reason is a bit more obscure: it’s that the terms of condition of the App Store, the Apple App Store for iOS, makes it very complex to have GPL applications on it, while it’s easier to have LGPL applications on it. So VLC on Windows and on Mac and on Linux is GPL. The core is LGPL. But on iOS, the iPhone version and the Apple TV version is a type of different license called the MPL. And yes, I went and changed the license and it was a long story.

Yeah. So I think basically to change the license you have to contact all the contributors.
Yeah. So I think basically to change the license you have to contact all the contributors.
Jean-Baptiste Kempf
Yes. It’s very important to understand that open source projects are what we call in the US copyright law joint work, or in civil law collective works or collaborative works. It’s that you work all together in terms of the same goal, and then you create one software, which is one release. But the copyright is kept by all the individuals. Some open source projects don’t do that. They force copyright assignment, but this is not what we do. We’re communities. So everyone has basically copyright on what they changed. And this copyright stays even if at the end your contribution was deleted because the new contribution was based on your previous one, right? So if you want to properly re-license, you need to find all the contributors.

And at that time, I had to contact more than three hundred and fifty people. And sometimes, well, they’re just an email, right? So it’s… you need to actually track down. I actually, like, travel to some place to go someone that I was like, sorry, that I’d found online to see a– to go to their job and say, “Well, you licensed that. Can you– do you want to change from GPL to LGPL?” Most of the times they don’t even care. They wanted to help VLC. But also it brought me to very complex situation. I arrived to the work of a person who was a factory worker. And I said, “Well, I need you to sign that,” because it was his son who died who actually wrote the code, right?

So I had to explain all those types of open source meanings, and no, I was not a company trying to rip out the two lines or five lines that that guy did- … but was useful, and the whole community agreed on that, and he had no idea I was a factory worker. And I was a lot younger, right? Like it was fourteen years ago, and like I was almost in tears, right? It’s very difficult, right? We are talking about lives of people and he explaining, and we talked about the photo of this guy, right? So it’s important to do it right and to do it correctly. But yes, that means tracking down everything because every contribution works. There are some projects who don’t respect that, and we do re-licensing a bit, like, aggressively.

I would emphasize the community is such a wide-ranging group of people. There’s people in the Syrian war zone with electricity part-time. There’s… there’s people from all walks of life- … rich, poor, young, old. So it’s quite remarkable to get, you know, a group of people aligned on something. And that’s an achievement in itself.

We don’t care who you are. Sorry, it’s just like we have no idea to check. We cannot check, right? Like, maybe you’re a dog. I don’t care, right? I don’t care where you come from. I need to look at your code. And this is important because people don’t understand that, and they come to the community and send them some patches, and they get rejected, and they don’t like that because, I mean, you’re just like, “Sorry, it’s not up to our standards.” “Oh, yeah, but I’m an engineer at this very large company in Italy, in Germany, in the US.” We don’t care.

So one of the legends of the community is of course, Linus Torvalds, who created Linux and is a longtime maintainer of the Linux kernel.

Even at Microsoft’s cloud called Azure, I’m quite sure seventy, eighty percent of the servers are running Linux. All your Android phones are running Linux. What he did with the power of open source, sure, is amazing. And yes, the quality of the Linux kernel is very high, and yes, it’s difficult, but we cannot compromise on that. We cannot compromise on quality because in the end—and you have to understand that—the core community of VLC is five people.

The core community of FFmpeg is ten to fifteen, and we are the ones who are going to maintain your code, right? Because one thousand contributors in the timeline and just ten staying, it’s a one percent chance that someone comes and stays. One percent. So you will have change of job, change of wives, you have children, you have accidents in life. You’re going to change jobs, whatever. You’re not going to come back. It’s most likely. So we are the ones going to maintain your code. It needs to be maintainable. It needs to be excellent. And yes, sometimes that means that you need to rework your work because it was good, but it’s not excellent, and we need excellence because we are very few to maintain something that is critical for the whole.

And yes, sometimes that means that you need to rework your work because it was good, but it’s not excellent, and we need excellence because we are very few to maintain something that is critical for the whole.
Lex Fridman
But we should also mention that there is some spiciness, some harshness to the language that’s sometimes used when you’re keeping this high bar of excellence. Is there something to say to that?

It’s true, right? It’s also the fact that, for example, what we’re doing is low level. It’s extremely technical. You get into this community. The tone gets very like a type of— It’s a subculture, right? So people who arrive from the external are basically not known to the subculture. Most of those people around FFmpeg and VLC, we do VideoLAN DevDays, VDD every year. They are so fun in real life, and they love it. But it’s true that you’re online and sometimes, like, the tone, you don’t realize how it is. But that’s okay.

It’s a culture. I mean, you get this in the gaming culture. There’s pretty harsh, intense, the way people communicate, and it’s— everyone understands that the way you show love and respect just looks different in different communities. Sometimes people… It depends. If it’s a book club, usually people are going to be much sweeter. If it’s an open source project that’s very high stakes and used by millions of people-

But it’s very not often insults that you see, for example, in the gaming, right? And so Linus’ tone is a bit unusual even for the open source community. It’s more like it’s more harsh on the results, saying, “No, this is not good. This is crap.” Those type of things that you will see.

They come home. You know, terseness might be a thing, you know, it… And that’s not something to take personally.

And also you have to realize that most people don’t speak English as native language. And this is especially for open source projects like FFmpeg and VLC, which are mostly centered out of Europe. Sometimes people who are from the US or just are very not happy about the tone, but most of the time it’s also like they don’t know better, right? It’s difficult. The language is—English is a difficult language. There is so many subtleties and tone and so on that you don’t have, right?

I got twenty-four K upvotes, which is great, right? My karma on Reddit is amazing, at least on that account. So the question is, needs to be answered first, what is the story about VLC, right? Because yes, this is true, I refuse dozens of millions of dollars, yes, several times. Yes, I could be a multimillionaire and be somewhere on the beach. But I did not do it because I thought it was not moral and it was not the right thing to do. And this is very important for myself, is to be like, I work for the greater good, I work for people, and I don’t want—it’s not just by myself. But the reason is also because I did not feel that I’m completely legitimate to do that, and let me explain you why. VLC’s story is a very weird story.

In France, we have university and we have a type of top colleges, and those top of excellency schools are engineering schools, business schools, and basically lawyers and medical, right? But they’re outside of university, and in order to enter those, you spend two years working like crazy math, physics to enter those best engineering schools. One of the school is called the École Centrale Paris. It has changed name since, but it was called the École Centrale Paris. And because it was Centrale, they had to move it because it was too small after the World War II and they moved it, they wanted to move it to the central of France in a place called Clermont-Ferrand. And the alumni decided that this was not okay, right?

It is the school that Eiffel, right, the one who did the Eiffel Tower, attended to, right? So they said, “No, no, we are amazing, great school. We cannot do that.” And so they bought a piece of land south of Paris very near Paris. And it was a campus managed by a nonprofit of the alumnis, okay? Because of that, everything on the campus was managed by students. The university did nothing, right? So radio, TV, supermarket, library, defining who was going into which rooms. Everything was managed by the students.

It worked great, and I learned so much in my life doing those side activities, right? Because you’re twenty-two and you need to run your campus, else you don’t have electricity, right? So you care about that, right? But anyway, in the ’80s they did a full experiment of deploying a network mostly sponsored by IBM and 3Com, which was a token ring network. So token ring is something that probably almost no one knows about anymore. It’s a networking technology where you don’t have routers, right?

Everyone is linked. It’s like really a ring, and when you want to send a message, you talk to your neighbor who’s going to put the message to the next one, who’s going to put the things to the next one, in terms of ring. The issue with token ring is, of course, is that it’s very slow because every computer on the network needs to open the message, see if it’s okay. Is it for me? No, it’s not, and then send it back, like a token which is traveling around the ring. In the ’80s, you’re doing some Telnet and sending mails as university. That’s okay, right? But starts the ’90s, and the ’90s and start video games, and when you have high latency in video games, basically you die, right?

So in nineteen ninety-four, nineteen ninety-five, around Doom and Duke Nukem coming around, they want a faster network. So the students go and see the university and say, “You know what? We want a faster network. We need to work,” and also play video games. And the university tells them that basically, “Oh, I’m sorry, we cannot help you because you understand the campus is not ours. You manage it, so do something. And you should see some basically partners of this university and basically go away.” And they go, and they actually go and see the CIO of Bouygues, which is a large French company and who’s doing some TVs in France. And he says, “Well, you know what?

The future of video is satellite.” Well, today we know it’s not, but at least it was a good idea. In nineteen ninety-five, the first satellite dish, and he says that instead of having like one satellite dish and a big decoder for each of the students, which are one thousand and five hundred, what about you build, like you put an enormous dish and only one decoder, and you send the video directly on the network. And that required a very fast network. Today, it’s obvious, but at the time was, like, the first to do video streaming. So they built this project, which was called Network 2000. Of course, right, we are in the ’90s, right? Everything futuristic is called 2000, like-

And so they do the Network 2000 project. It’s completely hacked. It crashes after 45 seconds. That’s okay. The demo is 40 seconds. It leaks memory. That’s okay. They put 64 megabytes of RAM instead of the 8 or 16 you have, and the demo should have stopped there. And that was the Network 2000 project by the students.

MPEG-2 because satellite is MPEG-2 TS for transport, MPEG-2 video, and MPEG-2 audio at that time. And the project should have stopped there. Everyone was happy. They had, like, amazing ATM network at 155 megabits per second. They had probably one of the best networks in Europe at that time, and they stopped the project. Six months or a year later, two students arrive and say, “Well, you know what? Maybe other people care about video streamed on a local network,” and they create the VideoLAN project, VideoLAN. And one of them is called Christophe Massot, that is a good friend of both Kieran and me, and they start the project. It’s not even open source yet, and they spend around three years to get the school to agree to make it open source.

Bear in mind, television was the main form of video at the time. You could get new channels. In the ’90s, having even one new channel when you grew up with four channels, having a fifth or a sixth was a big deal, and so having this satellite service with, you know, dozens, even hundreds of channels was so groundbreaking.

So there was a ton of people who wanted… So in the end, they had, like, several dishes on different types of satellites, right? Because, for example, a lot of people were coming from the Maghreb or the Middle East and they went to different types of satellites. Anyway, the solution worked great, and they started the VideoLAN project. The VideoLAN project has several, and some are completely crazy solutions, like one how to create multicast on a unicast network, but let’s not come to that. It’s too complex. But the VideoLAN Client part is what became VLC.

Actually, they basically strong-armed the university to force it to open source, because the university did not understand that. And in 2001, it’s still early. But basically, yes, the university agreed early 2001 to make it open source. I joined the project in 2003 because that’s when I joined the university.

But it’s a continuity of a previous project, VideoLAN, the student project, which is a continuity of the Network 2000 project, which is a continuity of that and that.

And I can tell you that in 2005, the project should have died and I made it to continue the project. At some point, we were only two active developers. And I thought it was great technology and was useful, and it will be useful, and I made that my life and my time. And I made that grow from a few hundreds of thousands of users, millions of users to what we have now, which is probably billions of versions of VLC around the world and used everywhere. So that’s a bit the story of VLC. There is a ton of very funny stories around that. Many people from around the world working on it, like you said, in Syria or the middle of nowhere in India. But along the way, I got several offers which were either to bundle toolbars, right? You remember those horrible toolbars-

It’s not– I’m not against money, right? I’m very happy to make money. I created several startups and one I hope that is going to work very well. It’s the fact that I believe that you need to win money ethically. There is a right way of doing that, and doing sneaky advertisement or stealing data is not the correct way, right? For example, if Netflix arrived at some point and said, “Well, we want to put Netflix inside VLC,” probably the story would have been different, right? But they didn’t. The only people who came to us were shady ads companies.

It’s inspiring for others I think that are pushing the open source movement forward, that it’s okay to do these kinds of huge sacrifices if you believe it’s right.

It was, it was buried in very faint text or in the license text box that nobody reads at the bottom- … “Oh, I will be installing this toolbar- … and changing all these things,” and it was very common to have to, you know, you install a program to do something at the time of any sort.

To put yourself in the mind of a developer at that time, I think it’s very easy—to everybody listening to this, it’s very easy at that time to convince yourself to take a few thousand dollars- … a few thousand dollars to do it. To say no to much more money- … takes guts and takes vision.

The last offer I had was obscene, and they say, “Yeah, but imagine with all that money you could build something new, open source,” right? It was like the mind trick was… it was difficult. But for me it was just like, “No, this doesn’t work like that or this is not the right thing, so I don’t do it.” And again, right, it’s not that I don’t like money or whatever. It’s just like it wasn’t right.

FFmpeg & Google drama
Lex Fridman
Well, once again, thank you from me and from the rest of the internet. Let me talk a little bit more about the open source movement, about the fact that, as you say over and over and over and over, FFmpeg is and many open source projects are built by volunteers. So there’s a bit of drama recently, Kieran, on the interwebs, on Twitter. You have a spicy style on Twitter that I think articulates and celebrates all the incredible developers and development and the code, especially assembly, that’s involved in building some of these codecs and building some of this incredible technology. But that brings us to the… a bit of a debacle that happened. Tell me the full saga of what happened with the Google security engineers.

Just to be clear, Google are one of the biggest supporters of open source out there. They have been for a long time. It’s just I think some things kind of went a bit overboard this time. So FFmpeg itself—and this is not like a secret, it’s on the homepage, you know—it processes untrusted data. There can be security issues when you parse untrusted data. That’s very normal. But recently what changed was Google started using AI to create security reports on an open source project, FFmpeg. Volunteers had to deal with that. They did, they provided very limited funding, and they even went to the media first announcing how good their AI was before the issues could be fixed.

Kieran Kunhya
Yeah. It’s announcing how good their AI is, that they provided a standard 90-day industry deadline without really understanding the nature of volunteer-driven development. In addition, this vulnerability was on an obscure 1990s game codec. The way—and let’s look at it from their standpoint to begin with. Let, let’s you know-

Lex Fridman
Yeah. Can you steer me in their case?
Yeah. Can you steer me in their case?
Kieran Kunhya
Yeah, sure. They have substantial resources working on the security of open source projects that, you know, are ubiquitous, and they’ve used a lot of compute to do that and very expensive and very capable security researchers to do that. And that’s their viewpoint is they are contributing by doing that. But I think that’s where opinions differ. It opened up a lot of interesting fissures, I would say. It does seem that there’s a portion of the security community that look at themselves a bit like building architects that never have to go to site. You know, going to site is something that is a little bit beneath them, the actual day-to-day construction. They’re there to do their security things and it’s someone else’s problem.

The security industry also kind of has a very aggressive tone towards things. The language they use is extremely aggressive. They use very strong language like, “You will get popped.” So and to Joe Public, “get popped,” you know, means something quite bad. For them it means to get hacked. The way I would look at it personally is a little bit like the padlock on your home. Not everyone… The padlock on your home or, you know, the lock on your home is there to protect against the capabilities of what it’s there to protect. It’s not there to protect nuclear secrets. It’s not there to protect Fort Knox. And it could be looked at that they’re using AI at a level of scale to go and pick those locks and then say, “Hey, your lock’s not secure.”

You need to deal with this.” Whereas actually they’re the ones with resources to be able to fix this. But that seems to not be something either they’ll contribute to in terms of patches or in terms of financially. And the scale of AI is kind of the issue. The bug reports are very wordy. They’re very, very—it’s almost a denial of service by AI-generated bug reports on very niche codecs. And the other issue the security community has is everything is marked high priority. You’re going to, you know, “This is the most important thing in the world, and you need to deal with this. High, high, high, vulnerable, scary, scary, scary,” on a game codec used on one disk in 1993.

And that’s where the dichotomy lies. Going around telling everyone that their padlock’s not safe—well, that’s a hobby project of somebody. The safety of that codec is consummate to what that person thinks. It’s their hobby. It’s good that they’re security analyzing it, but it doesn’t need a big scary warning, “This is a critical vulnerability.” You may also recently see that there was another quote-unquote vulnerability. It wasn’t Google in this case, but a filter could overflow and have an integer overflow, and one of your pixels could be the wrong color. And this was marked high, 7.5 severity in red.

And at some point, the security industry needs to realize you can’t keep crying wolf like this because this just leads to people, you know, the equivalent thereof of putting password stickers on their PC. You know, you can’t just keep crying wolf every day. And I appreciate, you know, that’s their modus operandi is to create as much scare and fear. But from the Google standpoint, at the end of the day, they need to contribute either financially or with patches. Google uses FFmpeg at a scale probably you or I couldn’t even contemplate, millions of CPU cores. And yes, they contribute in areas mostly regarding their own products, so VP9, AV1. But in a wider sense, there’s a disproportionate level of contribution. Yes, they fund students. Yes, they fund Summer of Code.

So he posted about security engineers on Hacker News. His post reads, “The problem with security reports in general is security people are rampant self-promoters”—in parentheses, Linus once called them something worse. “Imagine you’re a humble volunteer open source developer. If a security researcher finds a bug in your code, they’re going to make up a cute name for it, start a website with a logo. Google is going to give them a million-dollar bounty. They’re going to go to DEF CON and get a prize, and I assume go to some kind of secret security people orgy where everyone is dressed like they’re in The Matrix. Nobody is going to do any of this for you when you fix it.” Uh, basically commenting on the sort of the incentives for the different people involved and misaligned.

And they also now have reward tools for fixing issues. So it, it has changed a bit because of that debacle. So it’s good, right? But we’ve seen—and we talk about Google—but we have seen like some other large companies saying, “Oh, you need to fix this bug because it’s critical in our product.”

Can you explain the XZ fiasco? The FFmpeg tweet reads, “The XZ fiasco has shown how a dependence on unpaid volunteers can cause major problems. Trillion-dollar corporations expect free and urgent support from volunteers. Microsoft Teams posted on a bug tracker full of volunteers that their issue is high priority. After politely requesting a support contract from Microsoft for long-term maintenance, they offered a one-time payment of a few thousand dollars instead. This is unacceptable. We didn’t make it up. This is what Microsoft Teams actually did.” And then you give the image and the details and all that kind of stuff, showing that these trillion-dollar companies are not giving much money, not giving much support.

They think an open source project is a traditional vendor that they have an SLA. They think a public bug tracker is actually, you know, a third-party vendor’s Jira where you can do all of these things. It’s not. It is there to report bugs. I think the thing that made this particularly heinous was the name-dropping of Microsoft, the name-dropping that this is a visible product. If this was just a general bug report, I think that would have made it a lot better.

Yeah, so they literally said, like, “This is a big deal because a lot of people are using it in Microsoft.” I wonder what happens psychologically. So I think what happens in these companies, maybe you can correct me, is they… You’re right. They just think of FFmpeg as like a vendor that Microsoft surely is paying a huge amount of money to. They kind of assume that in their interaction, and nobody anywhere on the stack is going like, “Wait a minute. Shouldn’t we be giving like millions of dollars to FFmpeg?”

And this is a very big problem in large—like we’re talking about some companies, but it’s the same everywhere, right? A lot of those companies. Like the… when we talk to that person, right, he was just like a manager on one project in Microsoft Teams, right? He had, like, never really discussed with the open source community. He had no idea, right? It was like… but the problem is that usually there is what we call OSPOs, right? Open Source Program Offices in those type of companies, and they are the ones who are supposed to discuss with open source vendors.

Donations have increased substantially. They’re still not enough to cover even a single full-time developer, but on both a, you know, awareness level and a technical level, there’s substantially more technical awareness and sort of awareness of the importance of FFmpeg as a result of X and what’s happened. I can say, you know, it solved its purpose. People realize the level of importance FFmpeg has.

And on VideoLAN it’s the same, right? Like for example, a, a very simple example. For more than a year, we couldn’t update VLC on Android because of a bug on the Play Store, on Android Play Store, right? The only way we got someone to answer was to put a very spicy, as you say, tweet saying that we are going to stop distributing VLC for Android, right? And we have around 100 million people using that. And now then someone from Android actually came and discussed to us, right? We had the same issue with, with Microsoft or, or like saying that we were going to stop distributing VLC on the Windows Store.

And unfortunately, we are so small that the only very strong power we have to solve those issues is blaming on social networks because it snowballs and now they listen to us. But so as large companies often have difficulty talking to us. Like for example, VLC, right, is probably one of the top 10 software used on Windows. I am not part of Microsoft ISV programs, right? I don’t have a point of contact at Microsoft, right? While I’m sure any other software, Adobe, Spotify, has a point of contact. I don’t have that, right? So raising awareness works. It’s sometimes very spicy, lot of drama. Well, X and Twitter are okay for that, but it’s efficient.

It’s not just that. We’ll talk about assembly later I’m sure, ’cause that’s its whole topic in itself, but it’s also celebrating people like Andreas Rheinhardt who do maintenance. It is, I believe unpaid, as a volunteer. He’s doing massive refactorings. Andreas Rheinhardt and Anton Khirnov rewriting ffmpeg.c with threading. Celebrating those guys, celebrating the untold labor that’s gone into this that actually doesn’t change anything from the user standpoint. The files are exactly the same, but wow, the airplane has been rebuilt whilst it’s in the air.

Like JB said, we don’t care who you are, where you’re from, what you do. Teenagers have written thousands of lines of assembly over the years. Give a shout-out back in the days to Daniel Kang. So also highlighting the work of people like Ruikai Peng. This is a 16-year-old, some of his first contributions to FFmpeg, actually doing and putting some of these quote-unquote security researchers to shame by actually finding issues and fixing them and being 16. There’s no barriers. There’s no barriers to you have to study at college under this person and understand these. You can learn C, and let’s be honest, it’s from the K&R book. Learn C. You can learn assembly. We’ll talk about that maybe a bit later. You can contribute to world-class technologies.

In VLC one of the oldest contributors called Felix, he’s the one doing everything on Mac and iOS. He’s starting working on VLC. He was 16. We had a guy called Edward Wang, who used to be a Google Summer of Code student who stayed for three years around VideoLAN. He was 14, right? And part of Google Summer of Code and Google Code-in, which were programs where basically we have students or high schoolers, we wrote a ton of assembly for x264 and for VLC and for FFmpeg, right? So everyone can contribute.

And he also did a good job because he didn’t play the alarmist CVE heist, create a CVE (which is like a public exposure of security), and do these big scary red 7.5 high priority. He just fixed an issue in Git after three days and just fixed it. He didn’t need to go and play a big security drama about it. And I think I posted, you know, “the kids are all right.” Whereas there is a portion—I’m not saying all security people do this, but there is a portion of the security community, as Alex said, that likes to hype themselves up by creating drama. They would have happily raised, “This is a high priority CVE 8.0” or whatever on an issue that actually was in Git. It wasn’t even in a release, it was in development, and three days later was fixed.

Like you said, they’re some of the best software engineers in the world, and they do contribute a lot— … even on the security front. And also, you know, I’m a big fan of Theo. Much love to Theo. He was part of this debacle and drama a little bit. I think when you just zoom out on the grand arc of human history, the drama contributed positively to everybody involved. Donations went up. It brought more attention to the topic, allowed everybody to bicker in a way that ultimately got them to figure out what FFmpeg is all about.

We say stuff, we say stuff- … but we can, we can leave it on. X is a perfect place for, you know, international rap battle. You say stuff. I say stuff about your mama, but it doesn’t mean, you know, I have an actual personal issue with her. And that’s what it looks like. The Theo situation, you know, JB can maybe expand, went a little bit too far and there was a little… But, you know, it’s just a bit of fun. It’s just a bit of rap battle. It’s a bit—it’s WWE. You know, everyone’s having a bit of fun on X. It doesn’t need to be taken seriously. You know, the teenagers thing, you know, that… So that guy was a Google employee saying, “Hey, you know, there are other ways to run an open source business.” You know, and there’s like, oh, man, just have a bit of fun, you know?

That’s what the point of this account is. And furthermore, if you can teach people about the ways of open source projects, assembly, et cetera, by doing that, I think there’s a lot to be offered here. It’s not dunking on people for dunking’s sake. It’s showing actually the story that I think X learnt is these are not big corporate open source projects. This is not Kubernetes where there’s, you know, hundreds, maybe thousands of people- … paid to develop this stuff. These are just people in their basements in their spare time, and if you can address that topic in a fun and entertaining way- … I think that that’s the good thing and that’s, that’s the value of X and then the reach we have.

And to be honest, right, like even at Google, Google is one entity, but so many different people, right? And there is a ton of Google engineers we work with all the time, and even like Google from YouTube to Chrome to Chrome Media to the rest of Google, those are very different type of entities. But what we do is efficient. And, for example for Theo, right? It went a bit too far. I had him… Like I calmed everyone down. I had him on the phone. We say, “Okay, like this goes too far,” and so on. But in the end yeah, it’s a rap battle, but it’s positive for the project. It—like the awareness we have on open source and, and I mean true open source from communities right now—is increased dramatically in the last two years, and this is useful.

Jean-Baptiste Kempf
There are many drivers, but weirdly the main one is that what we do in multimedia plays videos, and video is cool, right? And, for example, we have so many people in the community who arrive because they loved watching anime, right? And this is like the advice when people ask me, “What should I work on in open source? How do I start?” And my answer is always the same: work on something you love.

The second thing is that technically we, because we search for excellence, this is the best school ever, right? This is the best school ever of programming. If you’re good in C, in FFmpeg, if you know how to write assembly, I assure you you’re going to be one of the best programmers ever, even if you’re working on writing TypeScript, because this is the most amazing thing to do.

Andrew Kelley started Zig. He was an FFmpeg developer and started Zig after his FFmpeg school. I mean, it, it’s the place to learn so many aspects of programming in the real world, in a thing used by billions of people. You have nowhere to hide. You have to be open and honest about your flaws and, and how you can learn and be better.

And what is also interesting in multimedia is that you have 16 milliseconds to display a frame. It’s not like a game engine where you can basically slow down and wait a frame. So it’s, you need to be good, right? There is no choice, else you don’t have your video. And because of how codecs, if you miss a frame, you’re going to destroy the look of the video, right? So you need to be good. You need to be perfect to have the right thing. But also is that it’s not just pure programming in the mathematical sense, right? A lot of people don’t understand, but in order to program correctly on the open source multimedia community, you need to understand how computers work. And when you write assembly, you need to understand about CPU pipelining, right?

You need to understand how SIMD works, how the ALU works, right? You need to understand how I/O works, right? And this is what I think that is missing to a lot of engineers and software engineers today, is understanding what we call computer architecture. And, like, seriously, some of the debates is like, should we use this assembly call or this one? And people say, “Well, no, it’s going to be like three cycles on this type of CPU and this one,” and has massive impact on the output, right?

We should expand. FFmpeg is probably one of the biggest CPU users in the world. There’s proba- it’s probably running- … as we speak easily 100 mil- order of magnitude 100 million, maybe even a billion CPUs as we speak. So every instruction matters. There’s not… The impact, at least in terms of CPU, is massive for everything that we do.

Like so many people like, “Oh, I’m working for whatever consulting company and I’m doing some portal to download invoices for your PG&E.” Wow, great. Like, so many jobs are like that. You’re not going to tell that to your grandma. But if you go to see your grandma and say, “I do this so that you can play video on your laptop,” they understand. And this is very important, right? Because you’re working on VLC, FFmpeg, H.264. It’s in the end of hundreds of millions of people and you have an impact. And so you can be proud of yourself.

Yeah, those are side effects. My favorite quote on this topic is John Collison. He said, “The world is a museum of passion projects.” You know, everything out there is a passion project. And open source multimedia and open source in general, you can just do that so much faster. There’s such a faster network effect, you know?

I can open a cafe and that can be my passion project, but I have to get building codes, I have to build a building, I have to find a location, I have to do all the, you know, all sorts of things. Well, in the software world, that passion project can move quickly, it can be amplified by the network effect, and that amplification can be more than the sum of the parts. You know, you can be, you can find people interested in extremely obscure things and have a network effect and make something that is truly amazing.

And on that topic of passion projects, Tim Sweeney actually said in a reply to a tweet that was complimenting JB. He said, quote, “Many things in the world only happen because an awesome person decides to do it. This is the case with VLC.” And that speaks to something interesting to me, that it does seem that a small number of people, sometimes one person, can create something incredible in the software world. Like you said this over and over and over. I think JavaScript is an incredible thing created by initially a single person. Some of the programming languages like Python and C and Java, like just one person has this vision, has this design, and brings it—sometimes over a weekend is the initial spark.

I don’t, I don’t think they’re competitors. I think, I think the simple answer is, the short answer before I go into detail is: VLC is to FFmpeg as Android is to Linux. So they depend on each other, but they, they coexist because of each other. So they are a binary star system is the analogy I used.

Hence the three-body problem. But anyway. So a lot of FFmpeg pipelines involve the x264 project, which is a VideoLAN project. I would put a finger in the air and say 80-plus percent of those pipelines are dependent on a VideoLAN project. VLC, obviously, as we’ve discussed, a VideoLAN project, uses FFmpeg, gives it reach, exposure to weird files historically, used some donation money to fund FFmpeg development, and we’ll talk a bit maybe about some of the reverse engineering later. So it’s a binary star system. They work and feed off each other. Many of the developers are shared. There’s no central location. It’s a virtuous cycle working together.

… which is like an insane project- … but amazing. So, and x264 is one of those VideoLAN projects. And my opinion, for example, is that x264 was, is the most amazing encoder ever designed, and this helped the adoption of FFmpeg. A lot of people and large companies went through FFmpeg because they wanted to use x264, and x264 increased the popularity of FFmpeg. But also VLC had its popularity because it played so many files that were done by FFmpeg, right? So it’s many projects that are intertwined and work together.

And to give you an idea, right? When I compiled VLC for Windows, I compiled around 16 million lines of code, right? One million of those are inside the VLC repository, and FFmpeg in total is probably around two, right? But so it means that so many dependencies are outside. And if you also look at FFmpeg per se, FFmpeg also is integrating third-party libraries like x264, but libopus and so many others, right? So we all depend on each other.

History of FFmpeg
Lex Fridman
Yeah, that’s why I was hoping to do this episode as we are doing that just kind of joins FFmpeg and VLC- … because it’s really two of the same, like you said, binary star system and we’re all just orbiting it. Can we give a shout-out to some of the people along the way? We didn’t really quite talk about the history of FFmpeg, so maybe can you tell me about Fabrice? Can you tell me about Michael Niedermayer? Can you tell me about some of the key figures here?

Let’s just talk about the eras of FFmpeg, because there’s key eras and key people that made this possible. Fabrice Bellard, as you mentioned, creating the concept, and then probably in the 2000 era— I would call the era, Eras Tour of FFmpeg— is the 2000 era was Michael Niedermayer. So key things he got done was exhaustive support for DivX and Xvid at the time, and all sorts of weird variants of what’s known as MPEG-4 Part 2. So this predates the MPEG-4 Part 10 that we’re used to. So this was 2000 era video codecs where there were flavor after flavor of weird, weird decoders.

At the time in the 2000s, you needed a new player to play every different type of file format. So there was Windows Media Player to play Windows Media formats. There was RealPlayer to play RealMedia formats. And those were the other key thing in FFmpeg at the time were native decoders for those. I actually do remember being a teenager, I must have been, figuring out there was this one player that could play, could decode these files without having separate bloated players. Because at the time when you downloaded RealPlayer, there was a ton of other stuff in there, a ton of ads, a ton of other things, and just having a simple library that was fast led to that.

And then I think 2008 was a big change because that’s when H.264 got its maturity and I think something hopefully we’ll talk about a bit more. This was the beginning of high definition video. So H.264 was the key decoder of that. So I’d call that the late 2000s and 2010s, and that’s when the big reverse engineers came along and really did astonishing work. The beginning was a single player that could play Xvid, DivX, Windows Media, and RealPlayer was already a massive achievement in itself without codec packs, without weird stuff you had to download that had weird ads and weird spyware.

But I think the thing to emphasize is this task in the 2000s that Michael did was Sisyphean. It was really, the number of edge cases are poor beyond comprehension in terms of you could have a Chinese CCTV system that did one weird variant of MPEG-4 Part 2, what’s known as MPEG-4 ASP, and that was a weird variant, and you had to fix that without breaking everybody else- … times a million.

Jean-Baptiste Kempf
So, like, let’s talk about this amazing Ukrainian guy called Kostya, who was at that time living in Germany, and who was in love with Sweden, right? He— And the guy was the most… He’s like a lot of the people in the community are very clever. He’s one of those who are, like, borderline geniuses, right? He was able to reverse engineer extremely complex codecs and he does that, and we do a bit of engineering with Kieran, but clearly not at this level.

Yeah, so just for reference, one megabyte binary blob to reverse engineer is probably order of magnitude a month of work, and this guy is doing 20, 30 megabyte blobs. Maybe we’ll talk about that in a minute, about the subtleties of how you do that. But this guy is doing it for very difficult and very obscure codecs.

And did that for fun, right? And so GoToMeeting was a big problem with VLC because that was like the number one feature request for a long time, so I put a bounty. And the guy at some point said, “Okay, JB, I’m going to do it.” And in a matter of two months, and then he explained how he did it. He was just like, “Oh, I looked at the code, like this looked like a DCT that I used to see on WMV and so on.” He did that, and the funniest part is that the code he’s written is a ton of jokes. And there is a ton of JB, right, my name, and Kempf and Kempf and Kostya jokes inside the code. The code is beautiful, right?

So one of the things I wanna comment is I’ve gotten a chance to speak to some of the developers, some of the assembly language level people, and they all always make everything sound like it’s kinda easy. There’s a kind of humility because, maybe just the level of what’s required to do this stuff is so high that everything else seems easy, I guess is the lesson to take away from that.

So in the community, like some of the most impressive people are the ones doing reverse engineering- … and the other ones doing the assembly folds, right?

Kieran Kunhya
So, yeah, if you look at Kostya, for example, he looked at the world as a binary specification. He didn’t need documentation or anything. It’s, “I have a binary and I can figure all of this out.” And he regularly used the phrase “binary specification.” Ah, you know, it’s not a problem. And he would go away, and he would come back, and he would do interesting stuff.

Can you actually speak to the details or add color and texture to what it takes to reverse engineer a blob?
Can you actually speak to the details or add color and texture to what it takes to reverse engineer a blob?
Kieran Kunhya
Yeah. So let’s look at GoToMeeting, for example, is a good one because I record a meeting on GoToMeeting, for example. How do I play it back without needing this GoToMeeting player? There may not even be a player. I may need to send a recording of a meeting to someone that doesn’t have a player or whatever. So first of all, there’s a ton of other stuff there. There’s an actual video conferencing client. You need to go and find—it may be easy, it may not be easy to find—the actual module doing the decompression. You need a way to actually dump the YUV data from the module. So often it involves opening in a disassembler, trying to guess where the hooks are to incorporate that module and run that module natively to decode a sample file.

Kieran Kunhya
So figure out where this module is doing the decoding process and find a way to hook in and output the raw YUV data, ’cause you will need that- … as a point of comparison for when you actually do the reverse engineering, ’cause you’ll need to be bit exact or in some cases close to bit exact. And then you open up your disassembler, use a lot of intuition to go and figure out, you know, where the DCT is, where’s entropy coding. There is a kind of, not a rule book, but there’s always a pattern of some sort. For example, GoToMeeting, you know it will be a lot of screen codec tools. There’s also different variants, so often I think there’s, what, GoToMeeting 4, 5-

So as you mentioned here, going to Perplexity, GoToMeeting uses its own proprietary codec for older s- recorded sessions historically stored in WMV files that require a special decoder to play properly on Windows. Without this decoder installed, Windows Media Player and some editors cannot decode the video track, so you may only hear audio or see a black screen. Boy, do I remember that. But this is reverse engineering that.

This is key, right? Because the GoToMeeting is something that not many people know anymore, right? Well, you know about Zoom and Teams and so on. But like, now let’s fast-forward 10 years, 15 years, and like this is a Gotomeeting.exe for Windows 32 bits, right? Which is like, oh yeah, but I’m on Android, I’m on an iPad, I’m somewhere else, right? How are you going to do that? I’m going to be on RISC-V, on Arm. Those are blocked, but there are tons of files we need to support for the future. And this is why those type of work are exceptionally useful for humanity.

I just have to say, though, that reverse engineering process is mind-blowing. It’s crazy. It’s like, it’s a kinda like, you know, I’ve been reading a lot and interview archeologists. I mean, you just have so little signal. Yes, yes, you know over time you get so much experience, you understand the structure of the original code, so you can kinda start inferring basics. But you’re like archaeologists with a little brush trying to reconstruct the entire human civilization.

In many cases, you don’t have many samples so you have to figure out what all the different flavors are, and you may have a So CineForm, for example, is actually a collection of different approaches and toolkits within that codec ’cause often it grows naturally. And the hard part is finding a sample that gets you kind of somewhere to start without having to implement 10 different other things. So start there. I think thankfully at the time I found a sample by pure chance that had a lot of flat blocks.

Bit exactness, so most but not all video codecs, certainly from about the 2000s onwards, have a bit exact definition, so every implementation must produce exactly the same bits, bit for bit, in exactly the same data that comes out of a decoder.

For a given sample. So Lex’s implementation, JB’s implementation, and my implementation of H.264 must match bit exactly. That wasn’t the case in the ’90s of MPEG-2, probably fair to say one of the biggest mistakes the video industry made, and I think people who were in the room in ’92—I don’t think most or both of us were in diapers, I suspect—but have acknowledged… I would give a shout-out to Yuriy Reznik. He’s acknowledged that was one of the big mistakes of the era.

And you’re saying the encoders needed to be able to run tests and then the, the, the bit exactness—I mean, that’s a nice thing to guarantee.

I would, I would point out actually FFmpeg is unique in the sense that it’s, it has been a winner-takes-all scenario. You have… Browsers is a good analogy because it has to parse a lot of different content and render it in a particular way, like a decoder. But there still are multiple browser engines. There’s Firefox’s one, there’s Chrome’s one, there’s a few Japanese ones that are pretty decent. That’s not been the case in multimedia in general across a wide range of codecs. FFmpeg has kind of won it all, I suppose, in a sense because of, because of the fact that you can get—every new codec added is actually worth more than the value of that codec itself because it makes the whole thing better.

FFmpeg testing
Lex Fridman
That reminds me of a thing that you mentioned to me about FATE testing and, like, the insanely rigorous process that’s used to test everything that’s incorporated into FFmpeg. Can you take me through the testing process?

Kieran Kunhya
Yeah. So FFmpeg has a system called FATE, FFmpeg Automated Testing Environment. Because FFmpeg runs on so many different OSs and can be compiled with so many different compilers, there’s been a crazy number of configurations. So you can see the absurd combination of compiler variants, operating system variants, instruction sets. You can see at the top macOS has tons of different variants because it has iOS, it has tvOS.

So the compiler will sometimes compile C code incorrectly. For example, this happens once in a while.

And it’s a key part of what we do because you may be able to test something locally, you make a change, but actually that breaks GCC version 11 on Mac or something like that, and you’re able to then fix that. We also have miscompilation, so the C code, sometimes the compiler can have a bug in it where it creates the wrong output, and that can have quite a big effect sometimes on a video because of the way frames have dependencies. Even a small change in the output can cascade to actually quite big glitches.

I mean, for me, it’s really easy because I have a day job. My company builds… The company I started builds equipment for broadcasting sports matches between TV stadiums and studios, for example. We have to work with 10-bit video, and 10-bit video has a set of challenges that you can’t process 10-bit data natively on a CPU. So that means you have to stick it in 16 bits. So that means you have six wasted bits. So there’s different packing formats to actually pack the data more efficiently because when you send that over a network, you need to save that 40%. For example, on PCI Express, you may only have bus bandwidth to do that. And so I think internally we have about…

Some are industry ones and some are internal to our own hardware that we build. We have a, I think, a 5 by 5 or 6 by 6 matrix of every single format to every single other format conversion. In fact, one of them I sent you, and they’re all written in handwritten assembly, and they all support different CPU generations. So this is really traumatic, handling all these different combinations times a million.

Assembly code (handwritten)
Kieran Kunhya
Yeah, so no, no relation to the free OBS streaming service. But JB and I have started companies broadly speaking around the FFmpeg VLC ethos, so that’s really low-level work. So in most companies, this wouldn’t be written in assembly. It would be accepted that C is fast. As you can see from that, C is not fast.

For me, some of the headaches we have is around some OS that are difficult to support, right? Because if you look at VLC and thanks to FATE and FFmpeg, we run on… The last version of VLC runs on Windows XP and still run there and runs on Windows 11. We work on macOS 10.7 to the latest macOS, whatever it is, right, 26. We work on iOS since iOS 9; well, we are actually iOS 26, right? We support many types of Linuxes, BSD, Solaris. The last version still runs on OS/2, right? Like there is maybe 10 users of OS/2 in the world, and one of them is maintaining VLC.

Then you realize that this very small team around VLC and using FFmpeg codecs and all the other ones support more OSs than Microsoft or Google or Apple, and they have infinite amount of power and resources. But for example, the worst is iOS. In order to build on iOS 9, we need to do some very clever mixing of several version of the Xcode IDE and SDK from Apple, and do a type of Frankenstein version of that so that we can still support iOS 9, which is not supported at all by the compiler of Apple in order to still run on Arm32 on iOS 9. And you’ve seen on FATE that it was still supporting iOS 9, right? So my headaches are mostly related to the support of so many OSs.

And it’s important because, like, we receive so many people saying, “Hey, thank you. I still have my iPad 2 to watch movies,” and it still works on iOS 9, right? And it’s also an impact of, like, not forcing people to buy new hardware when it works fine if you optimize it correctly. Which brings us to what we were saying about assembly. It’s also fighting, like, the fact that you need to buy something new nonstop while you could optimize more, which is a lost art.

So when you write assembly code, you write this using the instructions the actual processor is using directly. So most of the time you would write in a language, let’s take C as a good example. The compiler would use that to create assembly language and machine code instructions for you based off your C code. And there’s a specific flavor of assembly that we use in FFmpeg that’s called SIMD, single instruction, multiple data. So this means, for example, say I want to add five to a number in scalar assembly, so this is what’s known as you work on an individual element. So I want to have a number of– I have the number ten and I want to add five. I use the add instruction, and I add five to ten, and I get 15.

Kieran Kunhya
With SIMD, I can have a whole vector of 16 different numbers. They could all be different. If I want to add five to that, I can run one instruction, and that one instruction sums all 16 elements. And that, as you can imagine, lends itself very well to video. Video is, you know, pixel grid, so I can perform operations on multiple pixels at the same time. The key thing that we do differently in FFmpeg is we don’t use any abstractions or any major abstractions on top of that. So there’s a part of the world that uses what’s known as intrinsics. So these are C functions that behave very similarly but not quite the same to writing assembly by hand. So the registers that data is stored in on the CPU, the compiler allocates those for you.

And well, I arrived with a few other people, mostly Ronald, Henrik, and Martin, and we said, “We need to have an extremely good software decoder because it’s going to take time to have hardware.” And so we wrote this project, which is beyond insane.

We are talking about probably 3 billion devices which are going to decode video nonstop because, for example, 30% of the video from Netflix are now in AV1, 50% of YouTube, right? So, and you often don’t have a hardware decoder because not many devices have a hardware decoder. And with dav1d, we realized that with one or two cores you were able to decode 720p correctly.

Philosophically, what’s important to realize is that we passed the time where hardware was going so much faster, right? We are at the end of Moore’s law. We have limitation for AI, for memory. You need to go down in the stack and optimize more to get more power from what you have, because our request for power, CPU power, GPU power are exploding while the hardware is not exploding in speed, right? So what people do is that they add more cores, right? But that’s basically like at some point you can add 250 cores, right? So what we do is to take every inch of the machine.

That is extremely- … complex. But basically, usually when you do move from one function in code to another, there is a way to save the registry, the state of the CPU to enter another function. And this is like standard.

It’s a bit complex. I would simplify this a bit. So, dav1d does things to abuse the calling convention. You could define the calling convention as I’ve written a function and I want to call another function. How is the data shared between the functions? Because there’s a convention, what’s known as a calling convention, and what dav1d does for optimal reasons is create its own calling convention sometimes. So if I wanna call Lex Fridman’s library, we’ve got to agree on a convention so that I can share data with you in the assembly language space. And one of the challenges in assembly is every operating s- well, not every operating system, but there are, well, at least four that I can think of on x86, Linux 32-bit, Windows 32-bit, Windows 64, Linux 64.

And so one of the amazing things Loren Merritt did, who we talked about before, was create a very lightweight abstraction layer, so you could write your assembly code once and it handled all the calling convention stuff for you, which was always a problem because you had to manage four different variants. But dav1d takes this even further, for speed reasons it does its own calling convention within itself to bypass the kind of rules, the rules of functions and say, “Okay, actually I’m gonna call a function this way because I know it’s within my library.”

Well, if it’s custom, no. But the challenge is in general, yes, and in terms of each instruction set. So the thing to also emphasize is we do this on every instruction set. So every instruction set has its own handwritten assembly, which is even more crazy. And that matrix has got bigger in recent years because of RISC-V, because of ARM64, because of the new SVE. There’s SME. x86 has AVX-512, AVX. So we do runtime processor detection. We see what the machine FFmpeg is running on or dav1d’s running on is capable of, because you could be on a laptop from 2008 where this isn’t there. Runtime detection, we set function pointers accordingly. And then from then on, off you go.

Yes. And in all that, we don’t even respect the calling convention of the operating system in order to be faster, because we know that we are going to be called from within our binary, so we can share data without saving all the registry in the common way, because that can lead to loading and saving registry on the L1 and L2 CPU and gets us faster. So that’s why I said that understanding CPU architecture, computer architecture is key. And this is also why it’s handwritten. I don’t know anyone, I’ve never heard any other project than Dav1d doing that. This is why Kieran calls it an art, right? It is an art.

I think in a mass world, there isn’t something on billions of devices. I know there are some specialist industries. I know in high-frequency trading, they take this really seriously, where they’re receiving feeds from a market, and they need to react within X number of microseconds, and so the instructions matter. But that’s not a mass-produced thing that’s on a billion devices. That’s hyper-specialized, running on hyper-specialized hardware. We’re running on all hardware from-

Sorry to linger on it, but, like, that’s a really counterintuitive, almost, like, revolutionary idea here, that there’s a huge amount of value to assembly. Like, what are we supposed to take away from that? Like, what… You know, there’s a bunch of people listening to this, they’re basically like, sorry, for myself included, you know, I programmed for many, many years in C/C++, going up the standards of C++, fell in love with C++, even meta programming and so on, and then transitioned more and more because of machine learning about 15 years ago to Python.

And so, like, for me in this Python world, JavaScript world, now vibe coding, where I’m just using natural language, sitting in my jacuzzi, drinking a drink… and just talking to the computer, like record stops. Why is the value to go back all the way down to the low level? Like, what’s the intuition?

Jean-Baptiste Kempf
Because you can get more power per dollar invested, right? And sometimes it’s going to be a problem that is limited by your hardware. A good analogy is what you see in quantization in LLMs, right? And people are doing, “Oh, I’m going to do that in FP8 or FP4 or some crazy things like Microsoft Phi, who did it in 1.5,” because you’re constrained by memory, because you’re constrained by the machine you can run. Because at some point we are doing real time, and I believe this is going to happen on AI inference also, is that at some point you need to get faster, and you cannot always get more powerful hardware, right? So you need to analyze code and see where, like, where is the mission critical, where are the things that are called nonstops.

And for example, dav1d is a good example. It’s going to be run billions of hours per day. That makes sense. It doesn’t make sense to be on the glue of FFmpeg- … CLI. It makes sense over there.

We are also arriving at a point where we’ve done so many great things, but the hardware is getting back to us, right? Because cost is increasing, because we need more power, and so you’re limited by either your CPU, your RAM, or your networking, and you need to optimize, and this is where value is going to be. Especially because, like, doing AI is going to help do the programming of, like, business, right? And so the core thing that you will not be able to vibe code are optimization for the hardware to be as fast as is possible.

So I personally wasn’t happy with the way assembly is taught in books and online, ’cause it’s very grammar-focused, and you don’t, in general, learn a language from learning the grammar and the structure. You learn a language by asking someone what their name is, and you start from there, and you go and solve real problems that you have when you want to communicate. You don’t learn sentence structure, and this is the interrogative and the adverb, and all the assembly books seem to be doing like that, going through every instruction, even ones that aren’t really relevant, explaining what they all do and how they… It actually doesn’t really change much.

So, and the other problem that we have in our community is assembly is taught sort of hand to hand, like person to person, like blacksmithing one by one. That’s the only logical sort of analogy, and that doesn’t really scale online. It doesn’t do other things. So I’ve started a set of assembly lessons in the way it’s done in FFmpeg, which is a little bit different to the way assembly in general for… I don’t know. I’m trying to think the other good big use case of assembly is in embedded devices, in really low power, cheap devices, and that’s completely different to what we’re doing here. I think it would be good if you could highlight the requirements, which are quite simple. It’s high school mathematics and C.

Kieran Kunhya
And actually not even C, really, really it’s pointers. To emphasize, yes, we’ve talked about how brilliant this stuff is, but high schoolers like Daniel Kang have written assembly in FFmpeg. I think there’s been contributions because of these lessons. So it’s really about trying to get this dying art to continue, because we’ve shown it’s possible with dav1d to produce something amazing. There’s still a lot of codecs in FFmpeg that are only maybe partially assembly optimized. And so it really starts with basics and continues, explains a lot of the jargon, a lot of the syntax. It doesn’t really try and explain to you, you know, interrupt handlers and interrupt instructions and all of these different jump targets; actually makes this really vector focused.

It’s a classic, yeah, it’s a classic example of FFmpeg. But some of this assembly language is really beautiful, and I think it’s beautiful because it’s kind of like flying a Spitfire. It’s really aviation at its purest, but also pushing the aircraft beyond what the designer thought was possible. So we’re abusing, for example, sometimes cryptography instructions to do certain things, and there’s a level of beauty and art where it’s really you and the processor.

There’s nothing in between. It’s you and the joystick of the cockpit, and you move that joystick, and it’s physically connected to the ailerons, and you can push that plane beyond what it can normally do, and there’s a level of, yeah, beauty and amazingness to go that. But I don’t think the sort of person-by-person assembly that is… someone taught me, and I’ve taught multiple people, is gonna work long run just because of the particular flavor and the way that we do it.

They had more of an understanding than I expected, but they are still… I’ve asked it questions, and it still goes and starts not hallucinating, but making modifications, and then I go, “Is it bit exact?” “No.” “Fix it.” And then it just goes and does the same thing, and it’s going, it… There isn’t the corpus of information like Stack Overflow to work on.

Jean-Baptiste Kempf
There is not enough data to train on. And this is the biggest issue. I started my career actually doing some assembly for Itanium, right? So the Itanium is a dead processor type, which was done by Intel and HP a long time ago when they wanted to do 64 bits. Well, they lost, and then we got AMD, who did it, AMD64, which became x86-64. But Itanium was extremely interesting in the sense that those were processors who had a ton of computing power to do floats, FMAs, which is similar to what we need now for LLMs, right? And you could pack three operations per line that could be loaded. So basically, you had an output of basically six billion operations per second, but the memory bus only allowed 1.5, right?

So your CPU was four times faster, so you had to do crazy things to pack things in memory or reuse the registers, and those type of semantics, no language could do that, right? So like I have the Itanium programming book because Intel did amazing books, but that’s exactly what Kieran says. If you don’t know what you’re going to do, it’s impossible to read, right? It’s a ton of jargon and so on. While those lessons are amazing because they are targeted to a real problem, and you can do it yourself.

And part of that in the lessons is a framework called x86inc, written by Loren when he was working on x264, and it allows you to do more things about that to create a type of like not caring too much about different calling conventions. And we had a lot of students who gave code to x264 using that a long time ago, right? So it’s really doable, and I believe it’s necessary to understand assembly language, even if you don’t do it much, to understand what’s going on inside your computer, and that will make you a better programmer. And I assure you that because doing that, you will understand some of the architecture of the memory inside your computer, right?

There’s a lot of focus on the self-importance rather than solving real-world problems. It reminds me of the Sinclair C5. Sir Clive Sinclair of Sinclair Computers built a car, and he said, “Oh, everyone will be traveling around in one of these electric cars.” And it was… Rust reminds me of that, where I think the community doesn’t quite understand that in order to get people to move, you have to build something that’s as good as, if not better than what you have now. Yes, people are doing Rust rewrites, but if they only do 85, 90% of the feature set of what we need, like things like coreutils, that last 1% takes 99% of the time.

To use Elon’s famous quote, “Prototypes are easy.” Like this kind of stuff is easy. But this, to get a real electric car, you have to make a car as good as, if not better than what we have now, and Rust isn’t in that stage yet. I think we’d– I don’t think anyone would object to seeing Rust code in FFmpeg, but it needs to work as well and support the same unit testing as everything else. It needs to be flawless. It can’t just randomly break. They can’t just randomly break ABI when they want to. It needs to have, I think, more– I think it still has only one compiler implementation. So it’s got to be as good as, if not better, and saying, “Hey, here’s my utopia of memory safety,” isn’t enough, even though we probably all agree that that’s the goal.

So I’ve done a ton of Rust, and the two major topics I had was adding Rust modules inside VLC. One of the reasons VLC got popular and which was one of the main architectural decision, is that VLC is a very small core and a ton of modules, right? And so you can write modules in C, in C++, in Objective-C, and anything that is basically interoperable with C. And so we did some Rust modules, and so I have experience on that, and I wrote some of it. And also, like, my new startup called Kyber, is an open source project mainly done in Rust. What Rust is extremely good in, in the sense that it’s a better C++ that cares about memory and allows you to do things about memory ownership that no one else can do so far.

However, it’s great when you start a new project from scratch, and you do everything in Rust. But it’s very not good when you interop with existing part. And some part of the Rust community believes that they need to rewrite everything, and everything will be better with Rust. And the answer is like, no. Like, I’m almost always, in all my years of being engineer, manager, CTO of startup and so on, don’t rewrite, right?

Is that– That’s the, that’s the initial instinct for a lot of people when they show up to a code base, probably before LLMs, is like… probably because they don’t understand the, the, the wisdom of the way things have been done in the past. They say, “Well, we need to rewrite it.” Hence why there’s a thousand JavaScript frameworks.

But the reason is the following, and this is very important to understand. It is an order of magnitude easier to write code than read code. And you see that also with LLM. They can write code, but analyzing is a lot- … more difficult. And so when you arrive to a very complex piece of code, right? You don’t understand it, right? Because it’s so much more effort to understand the code from someone else because you don’t have the thought process. And often I joke about some languages, mostly Perl for example, which has very complex syntax. And imagine I am at my maximum intellectual efficiency in programming, right? And I write the best code ever. I will not be able to understand it myself six months later, right?

Because reading code is more difficult. So very often you arrive, you don’t understand all the wisdom, all the business logic, the reasons that were done that is maybe not documented. And you say, “Well, I’m going to write it.” And the thing is, no, you don’t, right? Because that’s, as Kieran said, right? I’m going to rewrite coreutils in Rust. And then, of course, you arrive very quickly at eighty percent then ninety percent, takes a bit more time, and then you got the last ones, right? On the other side, right? So for new projects, it’s great. Everything related to parsing files networking because of the memory checker, boundary checker, it’s amazing, and there is nothing else.
Because reading code is more difficult. So very often you arrive, you don’t understand all the wisdom, all the business logic, the reasons that were done that is maybe not documented. And you say, “Well, I’m going to write it.” And the thing is, no, you don’t, right? Because that’s, as Kieran said, right? I’m going to rewrite coreutils in Rust.

Jean-Baptiste Kempf
To answer a bit differently for us, imagine I take a piece of software like dav1d or x264, right? Which has a ton of runtime in assembly, right? I rewrite the C part in Rust, right? So it’s more secure. Yes. But then you arrive into the assembly, and you can jump anywhere in the memory because we are doing handwritten assembly. So even if I rewrite the C part in Rust, for security reason, you break all the security when you write handwritten assembly because we can jump anywhere. So in my opinion, we need to do something that is secure assembly, right?

Jean-Baptiste Kempf
So which is compile time, check the assembly, which is similar to the checkasm projects that we’re doing on dav1d and x264 with VideoLAN, is to start instrumenting your assembly at compile time to check that it’s not jumping anywhere in the memory. Because else you might rewrite a part of C in Rust, but if you want to have the same performances, you’re going to have inline assembly, and so you destroy your whole security model. So that’s a bit what I think about Rust.

No, I just wanna… I would say on a personal level, I’m so in awe about assembly. I actually— Once in a… It never gets old, the speed improvements to show sixty-two x. So there are months, on a personal level, I run our internal test suite at work and just see I’m still in awe at the gains we have.

Well, there’s a source of joy and happiness with programming for different reasons. But I think one of the greatest happiness is in the optimization of code. And it sounds like you’re, like, at the cutting edge of that.

And in the community, I want to speak about two people who are wizards of assembly, right? The two of them are actually working living in north of Europe, Sweden and Finland. And Henrik Gramner knows so much about Intel x86 assembly that when we ask questions at Intel about things, they tell, like, “Why are you asking us, Intel? You have Henrik. Henrik knows better.” He knows all the cycles of almost all the SIMD instruction by all the CPU generation. “Oh, yes, this is a P4, this is a Nehalem, this is a Core 2,” et cetera. That person is, like, the best person on assembly in the world.

Yeah. But Arm in some ways is more com… x86 with out of order execution is not so bad. Arm, you really need to understand all the different generations of Arm processor because they’re all different. There’s A72, … … Et cetera, et cetera. And there’s the Apple variant, there’s this variant, there’s that, and you need to write code that works efficiently on all of them. x86, well, broadly speaking, you have Intel, AMD, and you have sub-variants, but generally speaking, there’s… Something fast is gonna remain fast on all of the variants, whereas in Arm it’s a completely much more complicated ballgame.

FFmpeg and Libav fork

We’re taking a nonlinear journey through history here, but we’re talking about Michael Niedermayer. And I wanted to ask about this. For a time there was a split in FFmpeg and Libav.

And the good thing is because of the license, you’re allowed to basically do your own, right? And this is normal, and this has happened all the time, right? At a point there was a GCC at the time of GCC 2 and EGCS which became then GCC 3, right? There is what we told KHTML with WebKit, with Blink. It is a same process. And also, like when I want to do a new feature today in VLC, I fork, I do my thing on my own, and then I merge back to the community. So there was a split in the open source community on FFmpeg, which become Libav and FFmpeg. And after a few years, well, the community merged back and people moved on. It’s a bit of drama that is normal in open source community, but forks are even… They’re important because they change the status quo of a community.

Jean-Baptiste Kempf
Not talking about FFmpeg and Libav here, but the GCC fork made GCC a ton better because some people wanted to change the architecture fundamentally to make it faster. And of course, it’s always question of people and so on, but in the end you realize that FFmpeg today is better than it was before the fork. And now, well, we’re back all together, right? And I spent a lot of time—and Kieran can say—in the community. It’s not often, to be honest, very well explained because a ton of the reasons are not very public. But I think that’s, that’s normal and that’s good.

So here looking at Perplexity, “FFmpeg and Libav split in 2011 mainly over project governance, leadership style, and development processes, not because of a fundamental technical disagreement. FFmpeg effectively absorbed Libav’s work while Libav withered and most distributions and developers moved back to FFmpeg.” Yeah, that was a weird experience ’cause, you know, I’m a Linux user, so, you know, whether it’s Ubuntu and so on, all of a sudden, I think for a little bit, Ubuntu, I feel like, am I remembering correctly, switched to Libav and-

Jean-Baptiste Kempf
Yeah. So to me it’s like the fork was like heated drama, but most of the development from Libav was merged back into FFmpeg, right? So de facto FFmpeg got a superset around Libav, and so that gave the user, because in the end we work for the users, a larger set of features and a ton of things that were discussed. For example, the debate on reviews, on how we push, are something that now is completely settled in FFmpeg and is following what mostly what everyone in the community agrees, right? So de facto, everyone who was active on Libav came back and worked on FFmpeg because the disagreements were fixed, and in the end, FFmpeg is stronger than it was before, right? And- … I know people love drama, but-

Well, my main concern, I understand, and I think looking at the long history, it’s all for the good. But I do… I am concerned because there’s so few humans that are critical to the success of open source projects that I have seen it be a psychological toll on folks and, you know, sometimes leads to burnout. So you have these incredible people that are at the core of open source projects. There is a moment that happens ’cause, like, what is the motivation of doing it? Ultimately, it’s because you’re passionate about it and it makes you happy.

Yeah, but it’s not just about forks, right? So it’s a very- … what you are referring to is one of the most challenging and most interesting part of open source today is maintainers burnout, right? And AI is a problem because of that. And Daniel Stenberg, who is the maintainer of curl, who’s probably one of the best promoters of open source in the world—he’s, by the way, a member of the European Open Source Academy with me, so I’m very, like, humbled to be in the same community as him, right? He’s against what he calls AI slop, right? Because it gives a ton of fake reports or- … bad reports, bad patches, and then a lot of maintainers have a lot of burden to maintain the software. And this is straining the mind of open source developers much more than forks.

And for example, the XZ fiasco was because there was one guy maintaining it, and he got basically hammered by two attackers who were asking him questions nonstop at weird times at night to block him, and at some point he got fed up and said, “Okay, I can’t do that,” and gave the commit access to the attacker. So burnout in the open source community is something that exists, but mostly it’s about maintaining things, right?

In the security community, they certainly did. That was one of the things I think that argument came out is there was a portion of the security community who’s like, “No, these guys write crap code. They need to fix their crap code.” I’m like, “No, no, no, no. This is a guy’s hobby project. You have a security bot that’s gone and found some AI-generated stuff. That guy didn’t write crap code.” It’s just an edge case to the 99.99999 percentile he didn’t think about because it’s his hobby project decoding Star Wars games.”

Yeah. I think I did also Basics and then Turbo Pascal when I was, yeah, end of elementary school. But mostly the first time I actually did some serious programming was the, the first year of you call that middle school when you’re 11? I was living in Italy for a year in Florence and it was amazing year. And like the maths teacher told us to, to work in a programming language called Logo, where you had a turtle that was designing things- … On the screen, and you would turn left and right. And in the end, we used that to do a very complex programming because of course you could do things. And, and this changed, like, as I knew I was, I wanted to do things with computers and program.

Kieran Kunhya
So, so H.264 is a video encoder for the H.264 video standard. It dominates internet video, but also other areas such as Blu-ray discs. And Blu-ray discs are interesting because the people that make them really want the highest quality, and there’s some really cool high-end films that have been encoded broadcasting and all sorts of other areas. H.264 was a big step change ’cause it kinda happened at the right time as well. A lot of the development took place when HD video was coming out. Intel Core 2 and Nehalem CPUs were getting fast. You could do real-time video. But the most important thing was a key sort of focus on visual metrics.

Kieran Kunhya
So industry and academia for 20 years before, was obsessed with mathematical metrics or what’s known as peak signal-to-noise ratio. So mean squared error, logarithm of mean squared error, and that led to tons of issues because mean squared error leads to blurring because you actually want to minimize– You want to add a little bit of error to everything to reduce the mean squared error as opposed to having a big error, and that led to loads and loads of blurring. So hobbyists bucked that trend. It was for their own personal videos, mostly anime. So there were two things they did differently, and there was a big iterative feedback loop with the community. They did some stuff differently.

Kieran Kunhya
Yes, exactly. As opposed to what industry– Some parts of industry are still obsessed by this, which is mathematical numbers that don’t look good in reality. And then adaptive quantization was the other big one where it was biasing bits against complex areas and redistributing them to less complex areas like grass. Grass has some high frequencies, but it’s kind of– it’s less complex overall compared to more complicated things. And this came around by ParkJoy. So ParkJoy was really the canonical sample that was… Is the running around in the park.

And this is, like, phenomenal to optimize and get perfect quality in a constant bit rate. There was a lot of optimization, mostly by Loren also, um- on anime, right? For a long time, anime was very badly encoded because there was a ton of banding, right? And so you see those issues, and there was a ton of things. So x264 is, like– And today it’s still the reference to any encoder, new encoder, AV1, AV2, VVC, HEVC; everyone compares to x264.

One of my favorite films, Cinema Paradiso, I know the engineer who created the Blu-ray, and he showed me the comparisons of x264 versus others, and the… it’s completely different. And I think a bunch, a bunch of guys in the Blu-ray world started using x264. Um, I think the big one was Chris Henderson from Warner Bros. He did the whole Fringe box set with that. So quite, like, a thing a person on the street actually watches and wants to look good. And so they kind of took a risk in their jobs doing that because they’re in a big company. That big company can buy whatever they want.

I think that’s the key thing.

some of the people who are, what we call fansubbers, are basically translating themselves to make subtitles, right? And at that time, you download completely illegally.

Yeah. The way you produce it is not– You, you mostly produce it, like, on screens, right? Since a bit of time, and you have all those gradients, right, in colors? Because they are very easy to produce digitally, very complex to produce in real life. And, and the subtitles also are very complex because you need to have often the Japanese and then you need to have the diacritics, right? The what we call the ruby, right? Which is the hiragana and the katakana for the kanji. And then because of course you, so that you have the official subtitling, but you also need the English subtitles or the French subtitles because you want to learn that, right?

Let’s be honest, all of those codecs since MPEG-2 video are the same concepts. The same concept about inverse transform, about intra prediction, motion compensation, entropy coding, all of them. However, each generation gives you a bump between twenty-five and fifty percent more compression for the same quality. And so you had the MPEG-2, you had the DivX era, you have H.264, which was, like, changing, right? H.264 improved so much. And then you had more, right? You had HEVC. You had VP9 at the same time of HEVC. VP9 is a bit similar to HEVC in terms of quality compression, but it’s royalty-free. Because in multimedia there is ton of patents and the licensing after H.264 became out of hand, right? And could cost hundreds of millions of dollars per year. So it made no sense.

So Google did this VP9 and the Alliance for Open Media did this new codec called AV1. So you can imagine that AV1 saves between forty and sixty percent less bandwidth than H.264- … for the same quality, visual quality.

At a given bitrate.

At a given bitrate, right? So that’s really like you increase the quality– either you set the bitrate and you increase the quality, or you set the quality and you decrease your bitrate. But because now you move from SD to HD and HD to 4K and 4K to 4K HDR, like you increasing the size by like factor two, three, four, right? So you need to have better compression to keep it in terms of something that is manageable.

But because now you move from SD to HD and HD to 4K and 4K to 4K HDR, like you increasing the size by like factor two, three, four, right? So you need to have better compression to keep it in terms of something that is manageable.
Kieran Kunhya
It’s more coding tools, more bigger blocks, lots more sub-partitions in each block. It’s just exponentially more complex.
It’s more coding tools, more bigger blocks, lots more sub-partitions in each block. It’s just exponentially more complex.
Jean-Baptiste Kempf
It’s more complex because the encoder needs to search more possibilities, right? So you, for example one of the things that is easy to understand is to predict a block, a color block to another, you have directions, right? So you can go left, right, bottom, up, and then in terms of like the other quadrants, right? What I call north, northeast, northwest, and so on, right? But that’s eight directions. Then you can do more direction. You can do sixteen or sixty-nine or one hundred and twenty-eight, right? You can– And every time your encoder is going to spend more time to see, oh, well, this block is exactly this one and those type of tools that you can bring, and the encoder needs to check which of the tools are going to compress you better.

And so I guess that AV1 encoding is two orders of magnitude more than H.264 in terms of CPU cycles, right? Order of magnitude, right?
And so I guess that AV1 encoding is two orders of magnitude more than H.264 in terms of CPU cycles, right? Order of magnitude, right?
Kieran Kunhya
Yeah. And as we discussed, CPUs are not getting faster. You’re just throwing more cores at the problem.
Yeah. And as we discussed, CPUs are not getting faster. You’re just throwing more cores at the problem.
Jean-Baptiste Kempf
But also it’s a fact that you encode once and you have hundreds of millions of users, right? So for example, YouTube, a very good example. YouTube encodes almost everything in H.264, but the popular video gets re-encoded in AV1 because it costs more, of course, to encode, but you encode once and you send that to millions, right? So it’s a trade-off between encoding time and complexity- … and CPU usage on the server side and on the client side. Because at the end, if you’re distributing a video to hundreds of thousands of people and the size is half of the other, then it’s better. It’s better for your battery, it’s better for your modem, et cetera, et cetera.

Video compression basics
Lex Fridman
So we can lay out, let’s say, the top five codec-container combos would be H.264 inside MP4 containers, AV1 inside MP4/WebM containers, ProRes for nonlinear editing inside MOV containers. So for people who don’t know, I guess ProRes is

Kieran Kunhya
It’s Apple’s codec for editing, originally for Final Cut Pro, and it’s designed to be fast to decode, fast to seek, because an editor will need to move very quickly. So it’s a different use case to the distribution element.

Jean-Baptiste Kempf
So I-frames, often key frames, are complete frames. It’s like an image. It’s a JPEG, right? You have… You can start, you see everything, right? And then the next image can be a P-frame, which is a predicted frame. So you take some part of the previous image saying, “Well, I need the block five and seven and forty-two,” and you replace it, and then you just give the extra information, right? But that means that in order to decode this P-frame, you need to have access to a previous I-frame, right? And then, of course, you have more complex ones, which are B-frames, which are bi-predicted frames, which can depend on different type of frames, some in the past, some in the future. And so ProRes is an intra-only codec. For the people who can see, this is-

But for me, for me, the biggest mind-blown when I started was the B-frames. B-frames means bi-predicted frames can depend on frames that are coming in the future. That means that in order to decode this B frame, you need to wait for the next frame that is dependent- … buffer that, decode that one, so that you can decode the B frame, right? So the way you decode the frame, the decoding order is not the same as the display order. Right? That means the encoder needs to be very clever and decide that, “Well, you know, I’m going to depend on things like in the future.” So this is like-

The fact it works so smoothly every day is kind of miraculous in some ways. It works so… You can have a stream that works across the world on their decoder versus one in the US versus one here of different manufacturers, and they produce bit for bit exactly the same material. That’s quite remarkable, and do quite complex things, and getting more and more complex and still be bit-exact. There’s a lot of work that goes into that.

There’s a lot of knobs you can control in this whole process. There’s a lot of really fascinating parameters that I’ve gotten to know more and more over the years that FFmpeg gives you complete access to. Maybe you could speak to some of them. So first of all, like obviously, we can lower the resolution, we can lower the frame rate, we can use different kinds of codecs, as we mentioned, from H.264 to AV1. There’s ways to tune the trade-off between bitrate and quality, as we’ve kind of spoken to. You know, you could do constant bitrate, you can do constant quality, say CRF, QP. You can do the longer or shorter group of pictures, GOP, that we mentioned. I mean, all that kind of stuff. It’s crazy. Number of B-frames.

Yeah. What is crazy is that a ton of people’s job is to optimize those parameters, right? A ton of people that you see at YouTube, at Netflix, at Meta, and so on, they’re not writing codecs. They’re just like finding the right parameters for the file they have, for the format they have, right? Because like something that is for a movie or something that is user-generated content from your phone or a screen recording or something that you’re going to video edit, you don’t want the same things. And there are thousands of people whose job is just to optimize all that.

Yeah. They’re wizards. Hats off to them. YouTube, like, to deliver—all the streaming sites actually, to deliver at scale. And like YouTube is really magical because it’s not just doing like what Netflix does, which is one-way broadcasting type thing. It also has to upload videos from all the places. So they’re also doing encoding at scale- … for videos that are gonna be watched by like five people. And it still has to deliver them on a moment’s notice. No delay, nothing. I mean, very minimal latency. And also serve it in all different resolutions. Like YouTube is basically the web version of VLC.

Jean-Baptiste Kempf
Yeah. Well, actually, it’s funny because, like Google Video, which was something they did before they acquired YouTube, was actually using the VLC plugin so that you could run VLC inside the web browser using the ActiveX plugin. And so it worked in Internet Explorer, and you were actually running VLC inside your browser. Which is funny because today we have the opposite, where we have VLC WebAssembly, where we compile all VLC and FFmpeg to decode, to run VLC inside the JavaScript virtual machine with WebAssembly.

… which was basically reading your document folder, encrypting that, and sending that. And the thing is, this is very clever, to be honest, because once you’re watching a movie, right, you’re going to do that for two hours, and you’re not going to touch your computer. And sometimes it’s normal because it’s HD that your fans are going up and say, “Vroom,” and there is a ton of CPU usage because you’re using VLC, right? That’s normal. But the thing is, what you don’t see is that’s actually a powered version of VLC that is used by the CIA. We had exactly the same problem with Chinese hackers that were targeting Indian people, and that got VLC banned from India until I had to fight in courts in India, the Indian government, to unban VLC. They didn’t use VLC.

They took just one DLL, because we signed the DLL correctly and they used that DLL to do another program. So you had the vlc.exe and was calling libVLC, but it was calling it into a fake one. And they used that to, to target. There is not much we can do actually to block those type of hacks.

Absolutely not, right? We have a big issue for, like, more than ten years, is that there is a fake version of VLC in Germany that was reported for now for 12 years, and Google basically decides to not— They know what’s in it, but the binary is too big for their virus analyzer to analyze it. And so while if you’re in Germany, you can go to a website that is a fake version of VLC with a custom installer, and it’s very popular in Germany because their website is in German, and Google mentioned that before VideoLAN. And the weirdest thing is that it doesn’t do anything on your machine for three weeks.

And Google knows about it. They’ve decided not to do anything. The guys used dark SEO in Germany to do that at some point. And this is very damaging, right? Because one of the things that they are downloading is actually something that is replacing your ads inside your machine, right?

Yeah. So make sure wherever you’re downloading stuff, it’s legitimate. I’m part of the botnet. Speaking of which, so you’ve mentioned that VLC sandboxing is something you’re working on, and it’s actually something quite challenging. Why is it important? Why is it hard?

Jean-Baptiste Kempf
So VLC is a core with around 500 plugins, right? One of them is FFmpeg, but we have, we support so many other formats. We support new protocols, we support new filters, we support weird architectures. And in this release of VLC, you have modules that are going to call your drivers, right?

Jean-Baptiste Kempf
Mostly the hardware decoders, which are going to call your Intel, your NVIDIA, your AMD driver. And all calling FFmpeg, right? And there might be a security issue. There might be a security issue in the shader, there might be a security issue in VLC, in FFmpeg that is going to basically crash. The issue is that you’re running VLC like every, every other program, like Adobe, right? You’re running it on your machine, and it has access to all your documents, right? So the idea is to be sure that you do a sandbox so that we can protect from ourselves, because inside the VLC process is running some code that is not even ours. Either it’s open source for other projects that we integrate in VLC, or it’s your GPU driver or something that is provided by someone else inside.

And so when we crash, we want to not allow people to do bad things, right? Because one of the common ways of hacking people is to crash a program, very often done with a web browser, very often done with PDF files, less often with multimedia, but that could happen. And when you crash, you launch something on the, on the machine of the person. Could be a ransomware, could be a botnet, right? So security of desktop applications is important. On mobile, it’s a bit different because most of the mobile applications are running inside their own sandbox. But for VLC, we could run it inside one sandbox, but the problem is that we need access to so many things that it’s basically we would have all the permissions, right?

And so if you have a sandbox and you put some holes everywhere, it defeats the purpose, right? So what we are trying to do, and we’re actually doing, is splitting VLC into several processes. One is decoding, one is demuxing, one is filters, and all of them run into their own sandbox so that if a part of VLC crashes, like Chrome crashes on some, on some tab, right? It crashes, but it does not crash the whole program. And this is what we’re trying to do. And it’s difficult because it’s a sandbox that needs to sustain gigabits per second-

This is all the kind of stuff you have to think about when millions of people are using. You, you’ve mentioned something somewhere where, like all the different features of VLC, when you have that many people using it, somebody will use every single feature, and they will tell you about it.

Ultra low latency streaming
Lex Fridman
I would love to sort of zoom in and talk a little bit more about the distinction between kinda downloading a file and watching it offline versus streaming. So the complexities, the challenges of streaming. Is there something we could say about what it takes to stream files? ‘Cause we’ve been talking about codecs- … and I think a lot of that implies encoding and decoding without having to communicate- … over the network. Sure. So can you elaborate, like, what’s required to do over network stuff?

Yeah, but it is less complex than it seems compared to everything that we’ve talked about. Especially because the most complex thing is not about streaming in terms of streaming services, but it was what was done to actually broadcast through satellites. Because in most of the modern broadcasting services, you can pause and you can go on. But when you’re sending live streaming, whether it’s broadcast or live for streaming services which are live, this is much more difficult because you need to encode in real time. When you go on a satellite, you have a specific size of the link, right? You cannot have a burst-

In the streaming world, what you have is called what we call adaptive streaming, because the difficulty– and it’s not really a video problem, it’s mostly a CDN problem, is that you might have too many people watching the same thing at the same time, and it’s a congestion of the network, right? So your player has difficulty downloading things fast enough to play them. So what happens is that locally, the player is going to read a lower resolution- … of it. But there are some very clever algorithms to do that, but most of it is quite basic, to be honest.

Yeah, you start to download a segment, what we call a segment, and then you time, right? And if it takes more than 50% of the time to download a segment, you go down to… Right. And the difficulty is more about when do you go up in bandwidth, in quality. But this is not very complex to do. When you encode, you’re going to encode seven resolutions, right? And you’re going to give the bitrate. The difficulty is to have your encoder give the same bitrate, but it’s not as strict as it used to be. So-

Probably YouTube has to figure out the human psychology side of that, like how pissed off do you get when it’s like very low bitrate and how long should it wait before it increases the bitrate even though the connection is better? Because maybe the changes in the bitrate is what, like, affects you psychologically.

The– you can kind of notice when they move from full fat AAC to the– there are compressed versions of AAC that use spectral band replication. You can kind of see it goes a bit tinny, and that up and down is very jarring. The video side is a lot smoother, and there’s less notice. It’s really the audio you can definitely feel it from when it’s moved you from a different audio profile to one or the other. I don’t know. We’re surprisingly tolerant at skipping audio glitches. I’m surprised people I know who are not video engineers, how tolerant they are to watching sports at 30 FPS, for example, whereas it should really be 60. The world is a lot more tolerant to that, but audio people are very– There’s– It’s an immediate feedback mechanism of, “Oh, something’s changed.”

If you hear a glitch, you realize it directly. I get to fully realize that, I suppose. One of the things I’m afraid of when I listen to audio more and more, that I get to notice every single tiny detail, and that you can over-obsess when people in general are able to kinda blur their consumption. They can look past certain imperfections.

But then when you combine like an event that is, for example, a sport event that is probably going through satellite or- … somewhere else and goes to a central place for encoding, and then you need to encode this older resolution in real time. You don’t have time for QA. You need to push that to CDNs. You need to add probably DRM for protection. You need to have that over a ton of different devices. Then yes, it is complex. But– And also, like you’re in the web browser or in very much different devices that you use for television, where you had like a defined set-top box or cable box that you know where you control end-to-end. So it’s a challenge, but it’s less… I think the networking part while you agree to have 10, 20 seconds of latency, I don’t think this is very difficult.

Speaking of networking and latency, so your new effort, as we mentioned, is Kyber, which is aimed at ultra-low latency. As you say, every millisecond counts, and you’re applying that to remote control machines like robots, drones, computers. Can you tell me about it?

Sure. If you start from where we used to be, right? You used to use FFmpeg to encode files, right? And then we used FFmpeg and VLC to encode in streaming services, right? And then you need to go lower and lower. And the question was where up to where we can, can we go?

And this question is very important because there are many use cases where you need to be fast, and it’s when you have feedback interaction, right? We are not just listening to something, you’re actually controlling it, right? Because– And that’s the biggest difference compared to what we’ve done so far, is that I need video to have a feedback on something that is happening live, whether it’s a drone flying, whether it’s controlling a humanoid robot from distance, whether it’s controlling a hover, whether it’s playing a video game in the cloud gaming, because this is what I did on a previous job, right? I was CTO of a cloud gaming startup. And this is a very interesting topic because you push to the limit the network.

You need to care not about the quality like we’ve done on video, and we’ve talked about with H.264. You care about latency, because a millisecond is meaningful when you’re controlling a car, right? For– Well, you’ve seen, you’ve used Waymos, right? When Waymos don’t work, and that happens even if one percent of the time, there is someone that is basically remote controlling that. And this is exactly the stuff that we’re building. It’s really an SDK platform to do end-to-end control of machines.

Yes. And what we do is a bit different from everyone else, is that we take only one socket, one connection, which is a QUIC protocol based on UDP which is interesting because it’s done for low latency. It doesn’t have two of the, what we call the TCP head-of-line problem and the HTTP head-of-line problem. It’s ciphered by default, but on the same wire, we send multiple streams, like multiple tracks. We send audio, we send video, but we also send the commands, right? Mouse, keyboard, gamepad, and so on. And we do that while maintaining coherence, right? Synchronization. Because what people don’t realize is that all the clocks actually drift.

And when you’re controlling a robot, a robot is going to have, like, two cameras, five cameras, ten cameras, a ton of sensors, GPS, and so on. And if you want to train correctly your robotic AI model, you need to have all those that are in sync and coherent. And what we’ve done, and it’s all the stuff that we learned on VLC in broadcast in real time, and MPEG-TS that Kierans know well, is that we account for clock drifting. And so when I record a Kyber stream, a robot, I am sure that it’s going to be predictive in the way you play it back. And so when you’re going to do recording and training of your AI model, you need to be sure that every time you retrain based on the data, the data is going to stay coherent. And clocks actually drift.

Exactly. And also, if you’re going to control, right, I do something on robot, I need to be sure that it is actually happening at that precise time, right? And so we have on the server, which would be a robot, a time of, like, re-timestamping mechanism accounting for clock drift for that, right? So that’s one of the use case of Kyber to control robots. I also think, like, remote drones, remote whether it’s defense or non-defense, remote cars, remote submarines. There is many places in industry or remote surgery where the expert cannot go everywhere the machine is because it’s either dangerous or it’s too costly, right? So you allow people to have machines next to you, right?

The goal of Kyber is to make distance disappear because it’s either projection of skills or projection of power, right? So imagine we are all like— you’ve seen the Meta Ray-Ban and everyone else, right? You need to stream there, right? Because you’re not going to run anything over there, right? So you need GPU power whether it’s on a cloud, on a phone to stream that. And so all of these use cases need to be not about extremely low latency, but real-time latency for video. And so that means you need– we’re toying with the encoders so that the encoders encode a frame in four milliseconds. And Kieran with his company also goes under those type of latency, because you need to optimize at max the local latency, right?

Because it’s the decoder, the encoder and so on. Because this time is going to be added to your networking time. And it’s not just about low latency, it’s also about, like, reliability. We do clever things like forward error correction, right? So forward error correction is you over-transmit a bit of data, right, a few percent and while over-transmit, you’re allowed to lose some packets. Because all of that is very difficult over an internet network where you’re going to do things very far away. And if you check that all packets are delivered, you add a ton of latency. If you don’t want latency, what we do is that we over-transmit some data that you can reconstruct on the client side when there is things that are broken, right?

So and a few days, weeks ago, we were doing the demo around Las Vegas for the CES about— we had a rover that is fully 3D printed. It’s very simple. It’s a car, right? It’s a small car with a telescopic arm, and it was actually controlled from France, right? And the video was with a webcam and a very small server, right? A small PCB was basically running and send that to someone that is on the other side of the planet. And so there is so many use cases. You can also think about having AI who are going to control many drones and so on. And technically, we need to be amazing in video, we need to be amazing at networking, we need to care about any milliseconds in networking, in encoding time, in decoding time, and also you need to integrate very low level.

Jean-Baptiste Kempf
So far we achieve seven milliseconds from a Windows to Windows or Windows to Mac. And if you look in the timing, there is around three point five milliseconds inside the NVIDIA hardware encoder and around two milliseconds on the Intel decoder, right? So, like, the encoder plus the decoder is already six milliseconds, right? So in order to go down, we need either to have some other type of codecs or some better encoder that are faster. But four milliseconds would be the grail.

I want that because there is going to be millions of robots or- … drones are just rolling robots or flying robots or swimming robots, right? It’s just you, a machine that you control. And in order… Either you need to teleoperate them or when everything will be fully autonomous, you need to teleobserve them, right? You need to check what’s happening.
Jean-Baptiste Kempf
And in my view, in the future, like, all those remote cars will be teleobserved by an AI model, which is just going to say, “Well, everything is good.” And when it’s not good, say, “Hey, there is a problem,” and then you have an operator, right? And this is going to be about safety, right? When you have your humanoid taking care of your grandma or my grandma, I want to be sure that everything goes well, and I’m not in those type of horrible scenarios where the robot is dangerous. Or when I’m driving, I want, like, the car to stop when it should stop, and if needed, someone takes care of that, right? And so there is so many cases, scenarios about real time, and so the goal of Kyber is to make real time control of machine. Distance disappears.

And for me, it’s amazingly challenging, right? Because I would say that on video I’m doing okay, but networking I have so much more to learn, right? It’s about, like, congestion protocols, bitrate adaptation in real time. But it’s quite funny. And so I created this project and we have fundraised in the US, of course. But it’s open source, right? This is important, right? Like, we’ve not said that, right? But everything on Kyber is open source.

Jean-Baptiste Kempf
It’s a dual license, commercial and AGPL, right? You remember what you said- … about licenses. Basically, if you want to use Kyber in your product, you must have your full product open source. If you want to use this amazing technology but not open source, you pay the commercial license, right? So the small people or the hobbyist and the very small guys who want to do that, they can use the technology. They build something that is open source and cool.

Like we have– Like the rover we have is 3D printed. We are finishing a demo where it’s an actual wing, right? Like a type of drone wings that is also fully 3D printed. We are trying to do a sailboat that is 3D printed. And we’ll work on some humanoids. Of course, they are not going to be very good robots, right? It’s not our job, but we’re here for everyone to make robots. Cool.

AV2 codec and video patents

Ah, you’re talking to the right guy. I love robots. There’s a bunch of them upstairs. And teleop is gonna be really, really important, especially as the number of robots scales across the world. So 100%. Let’s talk about the future of multimedia. FFmpeg, VLC, but some of the codecs, we didn’t really mention AV2. So can we just lay out what is AV2? What is the hope for it? What is H.265, H.266?

Jean-Baptiste Kempf
So AV1 is this codec that is done by the Alliance for Open Media, right? Where there is Google, Netflix, Amazon, Apple VideoLAN, where we try to make a royalty-free very good codec, right? And now it’s being deployed. But actually, the codec was finished in 2018, but a codec takes years to be used in wide scenarios, right? So AV2 is the next generation of this codec. It’s 30% better, right? So if you keep the same quality, you get 30% bandwidth reduction compared to AV1.

That is AV2, like H.264. Right? Then you have an encoder. The current encoder is called AVM, and there will probably be other encoders, probably one called SVT-AV2, and those are the encoder. The same way x264 is an encoder to H.264, the same way that x265 is an encoder for the H.265 codec. And the decoders for AV1 is dav1d. The decoder for AV2 is dav2d. The decoder for H.264 is ffh264 inside FFmpeg. The decoder for HEVC is ffhevc inside FFmpeg. And there is a next generation codec from the MPEG world after H.264, H.265. There is one that is called H.266, also known as VVC.

For example, there are cases, especially for screen recording, where the gains are humongous because you arrive, you have the right tool that is done for that. And so for a specific video, a new generation is going to give you 70% gain or 80% gain. Right? But there used to be a ton more codecs, but now the two main families for transmission are H.264, H.265, H.266, and the other is AV1, AV2.

Jean-Baptiste Kempf
Yes, and the royalty of the patents. And this is the reasons why you see the AV version of codecs, is because they try to be as royalty-free—which means no cost for the patents—as much as possible. Because what you need to know, and we’ve not talked about that so far, is that multimedia is what we call a patent minefield. There are two places where you have the most patents. It’s everything related to 3G, 4G, 5G, RF, and multimedia. Because it’s very mathematical, and you can get great gains and so on. So Google and Meta and Netflix wanted something where it was royalty-free. There are people who said that they have patents outside, but they are fringe patents, right? So it’s mostly true that it’s patent-free.

And so that’s why we have the Alliance for Open Media, where we are part of, that created AV1 and creates AV2. We create also audio codecs. But yes.

But especially like what happened in France, and of course, sometimes a bit overdone with everything called French Tech, but today, most of the people who come on the market want to create startups. Fifteen years ago, it wasn’t the case.

It’s paperwork. So like, actually, if you had infinite trillions of dollars you would win easily because you’re on the right side. But the thing is, there is a degree to which they suffocate you with paperwork. That’s the downside of bureaucracy, through paperwork, through process. You know, it’s the Kafkaesque thing.

You have to realize that one of the good things, for example in France or most of Europe, is that the—Answering to a court order does not make you bankrupt, right? It’s not like in the US, where it can actually bankrupt you, right? There is—The way the law system works is that, like I receive lawyers’ letters every week, right? And I can tell you that the cost of lawyer fees for VideoLAN is less than ten thousand dollars per year, right? Right? So that’s not really scary.

There is no code that gets into VLC that we don’t control, and the way we compile VLC, you would call me completely paranoid. Like, we compile on boxes that are offline, where we start by compiling the compiler. We do everything offline on places that have never been connected to the internet. We— The way we do signing, there is double signature. And especially because, for example, we’ve seen, and we believe it’s a governmental agency that is not from the Western world who tried to push a fake binary into our own servers and that scared us a lot. And VideoLAN is open source. How can you kill it? Like, I move to where? I move to Malta.

I move to, I don’t know, Cayman Islands, and I change the domain name, and I start again, right? Like, VLC is a tool. It’s a tool that is going to help people doing things. We are not a platform. And for patents, well, I’m sorry, but most of the patents… Like, you shouldn’t be able to patent math and matrices. Like, this is wrong.

It would be difficult ’cause of the international nature. It would be difficult for you to incorporate that code because there would be someone in the UK and someone in Germany and someone in the US as part of VideoLAN who’d be able to see that. It would be extremely difficult.

The only thing that we can do, which happened, is like we had the issue— We had the case with some police in the US who said, “We have a murder case,” right? And the file is destructed or doesn’t play in that version of VLC. Could you help us?” Right? We never have access to the video. It’s like a normal support, right?

Jean-Baptiste Kempf
Yes. And, like, I remember in the middle of the Afghan War, right? I received an email from someone in the army, right? I don’t remember the grades, right? It was just like, “We have a big issue with the latest version of VLC because it doesn’t play correctly the file on an RTSP server that we have where there is all the movies.” And he says VLC is very important for the morale on the troop on the ground, right? Because at night I think it might be boring, right? So they have a collection of videos to watch or movies over there, right? So and, and of course I did an update, and I broke some support of RTSP, right? So I gave them another version just for them, right? Because it was important.

And because VLC is completely open source, I think it is allowed on the US Army laptops, right? Because the, I guess someone in the US military actually looked at it and say, “Well, okay, this is okay,” right? And the way we document how we process, that was okay, right? So the only way we work with authorities is to help them doing support.

Video archiving
Lex Fridman
That’s beautiful. Kieran, you said that there’s an active archiving preservation community? I think that’s super fascinating. You wrote that they’re stretched in budget, but they see the extreme importance of FFmpeg as a Rosetta Stone so that multimedia can be played a thousand years from now. I mean, that’s a beautiful way to see FFmpeg and VLC as a tool for preserving visual knowledge.

Yes, that’s right. One of the coolest communities in open source multimedia, mainly led by someone called Dave Rice, I’ll give him a shout-out, I think from City University of New York, is the archiving community. They’ve done so much stuff. They value open source, one, because yes, they lack budgets, but two, they see the fact that archiving video is important for the world, and being able to play that is a big problem. Famously in the UK, there was something called the New Domesday Book, and they archived lots of stuff on BBC microcomputers. Within 10 to 15 years, no one had the right software to play that.

Yes. We have languages that exist that haven’t changed too much. We have mathematical notation that exists. It will be like Latin. C will be like Latin. It will be a thing that you learn from the past, but it will still be usable in certain contexts. So the archiving community are really great practically. They, again, limited funds. They funded the development of the FFV1 codec, so that’s a lossless codec. So the archiving community is really scared about the act of compression losing things, and they have a fair point in this, you know.

If they compress too hard, it could change the view of the material. There could be something slightly different here and there, so they’re really concerned about things. They need to be not just compressed well, but lossless and be fast. And so they worked with FFmpeg to develop a whole new codec designed for fast software-based encoding. They’re really concerned about resilience, so if they’re storing on tapes or other hard disks, I lose some bits, I need to recover quickly. I can’t lose a whole GOP because I’ve lost a bit-

And it’s really about preserving the world’s multimedia heritage in a way that’s usable, and there’s a lot of great teams and a lot of archival groups across the world who’ve chosen FFmpeg and FFV1 as their archiving solution. And they can really provide us also super specialist advice. They can- … explain, “Ah, in the 1950s, colorimetry was done like this on this certain type of tape, and so there is this special case that you need to handle, and you’ll never get this anywhere else.”

They’re really, they’re really the model community, the model ethos of what we’re trying to achieve.

On Kyber, we also like do streaming of XR content on, for the glasses who cannot have enough power or inside the Apple Vision or the Quest. So we already work on streaming 3D, XR, interactive, low latency. There is something called volumetric video, point cloud videos, so it’s not stopping. And yes, at some point it will manage 3D data inside VLC and FFmpeg, right? It’s obvious.

So I suppose that there is a tension probably inside FFmpeg. It’s like, “Hey, listen, folks, we’re really good at doing video and audio, so like why expand? Like let’s do the thing we’re really good at doing.”

In order to answer that question, we need to answer the definition of what is multimedia. And multimedia is a digital representation of several streams for the human senses. And we will do that, right? So imagine there is now a way to not have a mic, but have a odor sensor- … and a diffuser of odors. It will get into FFmpeg.

That’s such an exciting future. Was it… I mean, it’s a small community of developers. How do you pull that off? Like if you’re a contributor to FFmpeg or VLC, it feels stressful. Like it, just looking on Twitter, it’s like a huge amount of work to make it work on all these different operating systems, an incredible effort.

Jean-Baptiste Kempf
No, see it in the other direction. We are not the contributors. We are the maintainers, right? So we maintain for everyone. Meaning that, for example, every year there is around 150 people who contribute to VLC and maybe 300 on FFmpeg, right? Our goal as a small team is to get all the contribution in. So if there is more usage, there will be more contributions, and those people will do the right module, the new format, and so on. We care about the architecture of VLC, the architecture of FFmpeg, right? Now we’re doing things in VLC, which is spatial audio, right? We did the demo not long ago. There was changes needed on the architecture, and we did the first spatial audio module.

When it’s going to add the second one, it’s going to be easy, or the third one is going to be easy, right? Our goal, and it’s going to be the same for others or haptic, right? We need to work the architecture so that modules can be added to add future capabilities. So yes, we are going… We are a multimedia framework, so that’s not just audio and video. It’s everything that is timed and represents something that you can sense. And if it’s brainwaves, it’s going to be brainwaves.

Lex Fridman
I love this on so many fronts because, so FFmpeg and VLC are pushing companies and pushing the world to standardize. So for example, to standardize- … brainwaves, right? So standardize… It would push, like I hope Neuralink comes up with a standard for multimedia via brain-computer interfaces or for robots with haptic.

Jean-Baptiste Kempf
By experience, what happens is always the same, right? You start, it’s a new topic. There is like five different standards because everyone starts to do this. The hype goes down because every time the hype goes down, then people start to say, “Well, you know what? We need to do a standard.” People, because two or three companies, usually not the leader, but the two or three followers do a standard, and then we implement the standard and then it’s the end of the curve. It starts to be more pepper.

Example, 3D audio, right? Six or seven years ago, it was everything about 3D. You go, you had the cardboard on Android. You had two audio formats. They’re all dead, right? And now it’s coming back with actual use cases, and we learn from the mistakes of the past standard. So it will be the same everywhere.

The two, my two favorites are, “Talk is cheap, send patches.” I think that, that- … embodies a lot of the stuff doesn’t get, as, as we’ve talked about, stuff doesn’t get built unless someone does it. It doesn’t just appear from the ether. The other one that I like is “FFmpeg, nothing is beyond our reach.” I think that comes from a US military satellite patch where I think they, they invented some kind of monitoring system that could see the whole world, and this was released.

And so they had some analog cameras- … and they were using some of the capture cards to go to analog to VLC, so VLC could stream on their multicast network for the whole CERN to access to that. And, like, I visited that in 2010 with Laurent and, like, we fixed their issue in an hour or something like that, right? Because it was some parameters maybe not well documented at that time. And he said, “Okay, for the whole day, what do you want to do?” And we visited everything. Like… things where with antimatter and colliders and so on.

The Viking long ships could average 70 to 120 miles a day. They could hit a place, raid it, drag off whoever they wanted, and get away before you could get your army there. That’s just absolutely terrifying.

What do you think it felt like for Alcuin and the monks to see the Viking ships on the horizon?
What do you think it felt like for Alcuin and the monks to see the Viking ships on the horizon?
Lars Brownworth
Honestly, I think it’s the end of the world, and I don’t think they were wrong to think that. The Anglo-Saxon Chronicle says the night before Lindisfarne, the monks saw sheets of lightning in the sky in the shape of dragons, and this was obviously meant to foreshadow the dragon ships coming up. But if you were brave, then you got taken to the House of the Dead, which was Valhalla. Every day you would fight, and whatever wounds you got would be magically healed that night, and then the next morning, you’d get up and do it again, so you’re essentially practicing for Ragnarok, the final battle. You know, there’s this poem by Tennyson, Ulysses, my favorite poem. I think it captures the Viking spirit.

The last line of it is to strive, “To seek, to find, and not to yield.” I think that’s very much like the Viking, you know, my purpose holds, to sail beyond the baths of all the Western stars until I die. We may die, but I’m gonna do this, I’m not gonna yield.

Introduction
Lex Fridman
The following is a conversation with Lars Brownworth, a historian and author of many excellent history books, including The Sea Wolves: A History of the Vikings and The Normans: From Raiders to Kings. He’s also the host of two history podcast series. The first, called 12 Byzantine Rulers: The History of the Byzantine Empire, is one of the first, if not the first ever, history podcasts launched over 20 years ago in June 2005. His second series, Norman Centuries, explores the remarkable rise of the Normans from Viking raiders to the rulers of kingdoms stretching from England to Sicily.

The start of the Viking Age
Lex Fridman
Your writing and podcasts take us from the Vikings to the Normans to Crusades, to the collapse of the East Roman Empire, also known as the Byzantine Empire. There’s a thread, I think, that connects the Vikings through all of it, so let’s start at the beginning. Let’s start with the Vikings.

Lex Fridman
So the age of the Vikings was intense and violent, as you write about, often dated from 793 AD to 1066 AD. It lasted less than three centuries. So the start is often dated to June 8th, 793. What happened on June 8th, 793?

Lars Brownworth
In June of 793, a group of Vikings, probably originating from Norway, arrived at the Holy Island of Lindisfarne, which was a monastic community, and they essentially slaughtered everyone, burned a couple of buildings, and grabbed everything that had any value and left. And that was the first Viking raid that came in force. And I do think Lindisfarne is a good beginning date because the terror that it brought really signified what was to come for the next two to three centuries.

And I do think Lindisfarne is a good beginning date because the terror that it brought really signified what was to come for the next two to three centuries.
Lex Fridman
So the word of it has spread. Like there’s a- there’s a bunch of accounts, like the monk Alcuin wrote about this event in a letter to King Ethelred of Northumbria, quote, “It is nearly 350 years that we and our fathers have inhabited this most lovely land, and never before has such terror appeared in Britain as we have now suffered from a pagan race, nor was it thought that such an inroad from the sea could be made.” What made this race so psychologically devastating to this monk and to the many other monks on the island and then to all of Britain?

Lars Brownworth
That’s a great quote. Alcuin was not just a regular scholar, he was Charlemagne’s favorite scholar and he’s largely responsible, as much as one person can be, for the Carolingian Renaissance that had done so much to elevate the early medieval world. In fact, the spaces we have, the punctuation we have, spaces between words are likely a result of Alcuin’s work. He was an extremely literate man, and you can hear the terror creeping into that.

Lars Brownworth
And part of that has to do with monastic communities, the Church and the- what they thought a monastic community was. So the Church was viewed as a sacred place. Everyone in Europe, everyone in quotes, is nominally Christian, and the Church is an area of safety. It’s a literal ark from the troubles of the world that you can flee to. I believe there are even rules in England, for example, that if you had killed someone, you could flee to a church and the civil authorities were not allowed to enter for up to 40 days. So you could have sanctuary there. And to violate this would’ve been the worst possible offense you could have given, which is why, you know, Thomas Becket’s murder is so, so horrible in England.

And the monks had dedicated themselves to a life of studying the Bible, to copying scriptures to prayer, to removing themselves literally from the temptations of the world. And so they would seek monasteries that were remote, and the most remote locations you could find were islands in the North Atlantic, because it’s just so difficult to get there…. So the ocean was considered a place of safety. Not sailing on the ocean, but these- these islands were- were literal havens of peace and security and closeness to God. And so the fact that the Vikings hit this place of all places you could hit was the worst, the most terrifying kind of offense against medieval sensibilities.

Now, that’s a very good question because… and it brings up a central problem of looking at the Vikings, which is the story is almost always told from somebody else’s perspective, largely from the pens of those they’re attacking. So they’re not gonna come across well. They’re often portrayed as demonic and inhuman. The Vikings themselves though, as much as we can piece together from archeology, from the stories they wrote later—but that was another problem there, the written alphabet, the runes. It was mostly used for spells, name your sword, things like that, curse someone, but it wasn’t really useful for writing long poetry or literature.

So the only Norse literature we have comes at the end of the age when they had adopted the Latin alphabet. So it’s… you can almost never see the Vikings in their own words as they saw themselves. But we can piece certain things together. Most importantly, Viking was not their day job. They were mostly merchants and farmers, mostly farmers who lived in little bays called Viks in Old Norse, which is probably where we get the word Viking from. One other note about how hard it is to tease apart what’s happening here is the English and the Frankish and the Irish writers all call them Danes, no matter where they came from.

They didn’t stop to ask, “Now, excuse me, are you from Norway, or are you from…” So they’re all called Danes or Pagans, heathen, or Northmen. So this is not very helpful in figuring out where they came from.

The language was interchangeable. You know, Old Norse was spoken in all three of those Scandinavian countries. But living in the north, so far up near the Arctic Circle, is… that’s at the very limit of where technology of the time could allow humans to survive. And that kinda harsh climate bred, I think, very hard people. Mercy was not a quality they seemed to favor or value. There’s a very famous story of a Swedish Viking putting a sword in the crib of his newborn son, and saying, “May you have nothing in this life but what you can gain with this.” I mean, I can’t imagine doing that. You know, to any of my children, you know, putting a gun in the crib, or-

So the understanding of the world is harsh, and that strength is the way you must face that world. So when you have those people, and especially the ones that self-select to get on a boat, to face the ocean with all the uncertainty, that results in the kind of brutality that we got to see.

I think so. I mean, the way they would build their ships, they were clinker built, so they were overlaid, like planks overlaying. So they were undecked as well. And so they’d have tents. So can you imagine crossing the Atlantic, the northern Atlantic, you know, with these huge waves splashing over with an inch of oak between you and the ocean? I mean, the amount of bravery that must have taken to undergo is astounding. Plus they didn’t have a compass. They navigated by, “Where’s the sun? Where are the stars? What… are there birds in the sky? Do I see a different color of water? Do I see leaves floating?” I mean, it’s terrible. If you’re traveling 2,000 miles, that’s not great.

So it’s kind of an intrepidness to them that I think is part of the reason why they’re so fascinating to us in our sanitized, more or less sanitized world. That this incredible courage to do this, and some horror at what they did on the other end when they arrived. But, you know, we’ll talk a little bit more about their religion, but they do not view the Christian God in particularly flattering terms. I mean, to them, he’s a weak God who won’t protect his adherents, and they can just come in and plunder as they… I mean, they’ll… One Viking famously says, “On land, I’m a Christian. When I’m on the sea, I worship Thor.” It was very much the kind of pragmatic take that the Vikings had.

Viking military strategy, tactics & technology
Lex Fridman
Well, we’ll talk more about religion, but since you mentioned the boats, what do we understand about the technology that they were using? Can you just speak a little bit more to this one-inch-of-oak idea? So, these were these longships that were also able to travel on rivers. So they’re not… Like, what is structurally, do we know about the boats that allowed them to be so flexible in terms of where they can travel?

Lars Brownworth
Yeah. I mean, and this was the Vikings’ great secret, and I think it’s underappreciated. They built different types of ships, obviously for different purposes, but the thing that blows my mind is that they built these ships that could cross an ocean, cross the Atlantic Ocean, and at the same time, when they had a draft of less than two feet, so they could sail up rivers that were two feet deep. And if they came to an, you know, a block or something, 20 men could pick up the ship and port it around. They were incredibly portable and their speed, the speed was the most frightening thing about the Vikings.

So they’re pretty sufficiently robust to handle the ocean and sufficiently mobile to travel on rivers and do so really fast, so- … you mentioned speed. That seems to be, from a military perspective, the great advantage of the Vikings- … because they can move much faster than the land armies can. So, and not just the element of surprise, which they often had, but the element of speed was the thing that gave them such an extreme advantage against the British armies.

That was the big one. So, an English army, if it had access to a good Roman road that was well maintained, which frankly there weren’t tons of them, but they could average something like 10 to 15 miles per day- … on a good day, if they didn’t have a large baggage train to slow them down. If you had a cavalry unit that didn’t have to travel with the army, they could average about 20 miles a day. The Viking long ships could average 70 to 120 miles a day. So, they’re just moving in super fast motion. They could hit a place, raid it, drag off whoever they wanted, and get away before you could get your army there. That’s just absolutely terrifying.

What do you think it felt like for Alcuin and the monks to see the Viking ships on the horizon? Do you ever think about trying to put yourself in the mind of those folks and imagining… In that time, you don’t have a full map of the world, right? And the oceans are not mapped, and you have a hazy conception of the world. And so out of the darkness from the ocean where you thought nothing can come, comes this terrifying, this brutal force.

And this obviously meant to, you know, foreshadow the dragon ships coming up. I can’t imagine the horror. It would shake my faith, I’m sure, to have these giant men jumping out of their ships with swords raised. And you’re… What do you have? Your cross?

Were the Vikings aware of the fear that they had caused? So, did they use fear as a kind of weapon, or was this just a side consequence of their actions, or did they understand and use it?

Yeah, yeah. The Vikings absolutely used terror. It was a main weapon in their arsenal. They would attack specifically on high holy days like Easter, Christmas, because they knew there’d be higher value targets there with richer clothing, richer offerings. There’d be a lot of money available. So they were rather sophisticated, which I think is something also that they don’t get much credit for. It’s like they were just dumb brutes attacking and just destroying. But they were… It was very sophisticated. They would show up. That’s what I mean when I say Viking wasn’t their day jobs. They would be traders in say an English port, kind of looking around.

They’d get everyone’s schedule, then they would sail away and come back as Vikings, and they knew exactly where to go. They knew where all the money was held. They knew where all the, you know, the churches were, when to attack. They knew the entire Christian calendar. They knew when someone’s baptism was, when someone’s confirmation. I mean, they were aware of all of this. And they would… They would definitely attack to increase terror.

One of the signs of the intelligence of the Vikings is that the Viking Age is so short. So what happens is these explorers and these rough men who do the raids, they very quickly are good at conquering and then start state building, or conquering and then establishing trade routes and stop being the quote, unquote, “Vikings.” So basically, they just… They conquer, and then they start doing the usual build the institutions, start a state, and now they’re normal kind of nation, civilization kind of thing. So this kind of force that is the conquering, raid, violent, intense explorers, it’s like a short-lasting thing, a couple of generations at most.

And so they would donate huge sums to the church. I think, you know, by the time of the French Revolution, which is obviously way in the future, the Church is the largest single landowner in France.

In some sense, religion creates this backbone of a society that stabilizes it, and then you create a bunch of rules about behavior, how you’re supposed to behave.

And then the Vikings here just test the system. I mean, it’s the fortune of geography for them and the fortune of their way of life to be able to raid, to become extremely rich and therefore this… It both spreads the terror across England, and the message across Scandinavia that there’s a lot of riches to be had. And so the raids, that’s why there’s an explosion of raids.

There was… The communication was terrible. You just couldn’t do it. And so it was wealthy and weak, and that kind of attracts predators. By the time the Vikings crash into it, you also have the added bonus for them of really feckless rulers.

And we should say, going to Perplexity here, that Charlemagne, also known as Charles the Great, is the Frankish king who became emperor in 800 and ruled much of the Western and Central Europe in the late eighth and early ninth centuries. And there’s a theory that the Viking age was also a reaction to the South expanding north, as you’re talking about. You tell the story of Charlemagne weeping because he foresaw the evil his descendants would suffer. Did the Franks accidentally wake the sleeping giant by crushing the Saxons and removing the buffer zone between them and the, and the Vikings?

I’m sure that had something to do with it. But yeah, as power was consolidated throughout specifically Central Europe, it did put a little pressure on the areas of Denmark. And those are the areas that first kind of erupt down toward… Norway and Denmark contribute most of the early Vikings that hit the Franks. And the Frankish Empire is the most wealthy state in Europe. It’s poured money into religious houses for the reasons you outlined. And all sitting there, easy pickings for people who’ve just developed the keel.

And so they, the word of the raids sent terror through England and through Europe. How much of the raids were reconnaissance, and how much was it just raids, and how much was it preparing for greater scale?

Definitely when Ragnar Lothbrok, for example, sacks Paris in 845, that definitely results in waves of Viking attacks throughout the 860s, trying to copy that. And he actually is the template which everyone wants to follow. And so that provokes large-scale invasions. And they hit England. They kind of switch off. When France is pretty much exhausted, they switch over to England, and then when England is pretty much conquered, they switch back to France. So I think a lot of these are just probing raids at first, but they’re proof of concept and then they come in force. For example, there was one king in England, his name was Ethelred the Unready, which is a pretty fun, funny… Pun on his name.

It’s not gonna work, but it will bring more muggers. So he paid the equivalent of 50 adult elephants, 48,000 pounds of silver, to get the muggers to go away. And it’s unsurprising that throughout the course of his reign, he paid something like 20 tons of gold and silver, which he had to tax his people for.

Yeah, I’m a romantic. I would like to believe he existed. I think probably he’s a compilation of a lot of different… There probably is a seed of truth there. There probably was someone named Ragnar. The last name’s a little suspicious. Lothbrok means hairy breeches. He supposedly had magic pants that would prevent him from being poisoned by dragons or snakes. That’s maybe a clue. We’re dealing with myth here. But he is really the template for Vikings. You want to figure out, like, what the Vikings wanted, who’s their success story, it’s Ragnar Lothbrok. He’s born Norway, Denmark—countries argue over that. Maybe Sweden. Some sagas say he’s in Uppsala.

Anyway, he is, you know, penniless, and when he is in his late teens or early 20s, he decides to invade, sail up the Seine. There is a well-known city on the Seine and he raids it. Supposedly, he takes the hinge of one of the gates from Paris to prove that he’s been there. The- the Frankish king, I love the Frankish kings because they- their citizens give them names based on how much they hate them. So you have- you have Charles the Great, right? Charles the Great, Charlemagne. He’s followed by Louis the Pious. That’s probably the best one. And Louis the Pious is followed by Charles the Fat- … who’s followed by Charles the Bald- … who’s followed by Charles the Simple or Stupid.

Uh, “Active in the ninth century during the height of the Viking raids.” And then descriptions of the raids and the exploits. “Medieval traditions link Ragnar to famous raids on the Frankish realms, especially the attack on Paris in 845, where he reputedly sails up the Seine and extorts a huge ransom from King Charles the Bald.” He’s also associated with repeated attacks on Anglo-Saxon England, embodying the archetypal Viking chieftain, charismatic, brutal, and focused on wealth, fame, and honor in battle.

Then also, what does he do with it, right? What does he do with it? So, he gets about 7,000 pounds of silver from Charles the Bald, which destroys, essentially destroys Charles the Bald’s kingship. But he goes back home to Denmark, and the Danish king doesn’t want him around, because he’s too powerful; he’s too rich. He’s a ring giver. You know, think Beowulf here, right? He’s got this large personal army which wants to join him for ad- he can do, you know, they’ll follow him, and he is a threat, and so he kind of is encouraged to go elsewhere.

They throw him in this and the snakes are biting him, but he’s got his hairy breeches on, so it’s not working. So, he’s singing a hymn to Odin and he gets pulled out and he’s asked why he’s not dying and he explains, rather foolishly, that he has these hairy breeches. So, they take the pants off and throw him back, and his last words are “When the boar bleats, the piglets come.”… by which he means, “My- I have sons,” he had 12 of them, “and they will avenge me.” And they do; they lead the the Great Heathen Army to invade and eventually conquer England. Ælla, fun fact, not so fun for him, is the, supposedly was captured by the son of Ragnar, his name is Ivar the Boneless, which is somewhat terrifying of a name. And he is, he’s the first person that a blood eagle was performed on.

We are all kings.” So they’re very like decentralized, tough. They only valued leaders who could prove that they had won. You know, could give out the rings.

Essentially, their Viking-ness is gone except for one thing, their, like, incredible vitality, which the Normans essentially conquer kingdoms at both ends of Europe, Sicily and England, and found two of the foremost powerful states in medieval Europe.

Rollo and Normandy
Lex Fridman
Yeah, and they change rapidly, which is fascinating. So you have a book. You have a podcast series on the Normans, so let’s talk about Rollo. Who was Rollo? The famous Viking war leader who became the first ruler of Normandy, Northern France.

Lars Brownworth
Well, first I should say, as someone of Norwegian descent, I’m gonna fall down on the Norwegian side of the argument here because- … Norway and Denmark almost came to blows over which was the birthplace of Rollo. But the consensus seems to be Norway- Not just biased.

Lars Brownworth
So he was… The only thing we… The only glimpse we get of Rollo as a young man is he was very tall, so he’s called Hrolf Walker, Hrolf Ganger, because he was so tall he couldn’t ride the little Viking ponies. So he had to walk everywhere. But… Kinda poor, probably raised on stories of Ragnar and the other Viking lords, and he goes. He may have participated in some of the earlier, like the 860 raids that the Vikings did on Paris or the Seine, you know, and then he eventually ends up plundering what will become the Norman coast. And in the year 911, he makes a treaty, the Treaty of Saint-Clair-sur-Epte, with the Frankish King, Charles the Simple, which is not stupid. It’s more like straightforward.

There’s no guile in how he talks. And Charles makes a really interesting deal with Rollo, which is, “Why don’t you settle here, integrate into the local aristocracy and defend the Nor- the French coast against the Vikings?” Which I don’t know. It’s like putting a burglar in charge of your security or some- I don’t know, but it works. It works. And Rollo, by the time he makes that deal, he’s probably in his mid-fifties to mid-sixties. It’s unclear when he was born, but the point is he’s lived the Viking life. He’s got something like 20 or 30, if you add up all the sagas they say that he… they gave him this many coins or whatever. He has probably 20 or 30 tons of silver that he has acquired and then probably given out to whatever. So-

Gets assassinated, but he does enlarge Normandy. So basically, every ruler after Rollo enlarges Normandy until it essentially becomes more powerful than the king- … By far. There’s a wonderful scene when- when Rollo signs the treaty. He becomes a liege lord of the French king, and there’s this- this great scene ’cause Rollo has to bend down and kiss the foot of the king. So Rollo’s probably, you know, he’s a Norwegian Viking. He’s probably, I don’t know, six foot.

Charles, this little Frank, he’s probably five ten. So he’s like Rollo’s towering over him, and he’s- there’s a large- both armies are watching. There’s a bunch of people who have come in from the countryside. They’ve heard something’s going on, and this important part of this feudal ceremony, you have to kiss your lord’s foot to- to, you know, be in a subservient role. And Rollo says, “I’m not gonna do that.” So he turns to one of his guards and says, “You kiss the foot,” and the guard’s probably taller than he is. So he bends down and he picks the king’s foot up to his mouth-

Lars Brownworth
Yeah, it’s hard to overstate Normandy’s impact on Europe in the Middle Ages. Of course, they’ll go on to conquer England as well. But Rollo, when he signs the treaty, it’s an ambiguous treaty. He’s given a title which is rather ambiguous. He’s not a duke, and it’s not clear. He’s not an earl. He’s not a duke. He’s just subservient to the king. Which means Normandy is not a duchy. It’s not a principality. It’s kind of this ambiguous, no one really knows what it is. And so Rollo, being a good Viking, and his descendants being good Vikings, despite becoming French, they just call themselves Duke.

And they essentially seize whatever power they want. There’s one Norman duke, I think he’s the grandson of Rollo. He’s kidnapped by the French king when he’s 14. He escapes the captivity and kidnaps the king. As a 14-year-old, I mean, it’s just—these are—these guys are crazy.

I’m a romantic, so I, when I read history, I usually end up rooting for the losers. I want Harold Godwinson to beat William the Conqueror. You know, I want Hector to beat Achilles. Never works, no matter how many times I read it. But I was always interested in the Normans because of the Norman conquest of England.

Lars Brownworth
“… force in the world?” And I started thinking about that, and my answer really is the Normans. The Normans, that’s the great change between Europe as a backwards, inward-looking place, and Europe as a kind of confident, outward-looking place. And that change happens under the Normans. I mean, the Normans, it’s not a coincidence that they lead the charge in the First Crusade. They create the state of England. If you look at England before the Vikings arrive, there are seven, it’s the Heptarchy, there are seven kingdoms in England, and the Vikings destroyed all but one. Only Wessex is preserved, and they’ve conquered about half of Wessex. And there’s a young king. What’s he gonna do?

But that king is Alfred the Great, and he conquers the rest. And then his grandson, Athelstan, is the first man called King of England, king of all Angles. And then they do the same thing almost wherever they go. They help create modern France by ripping apart Charlemagne’s empire, which was unwieldy. It looked good on paper, but it was unwieldy. It was replaced by this leaner, meaner, compact thing. They figure out how to deal with the Vikings by essentially building fortified bridges, changes to their army, and so forth. The Vikings, I like to call it creative destruction. They, by destroying the things they destroyed, they cleared the ground for something stronger to grow.

That’s brilliant. The creative destruction engine that created Europe was the Normans and the Vikings. And then you also, you have another book that talks about the Byzantine Empire, so you have the creative destruction that resulted in Europe, that Europe led to this Western, quote-unquote, civilization that we think of now. And the thing that protected Europe for centuries was the existence of the Byzantine Empire, the East Roman Empire, because of all the threats- … That came towards Europe. This strong, stable empire that is the Byzantine Empire protected the forces from everything that came from the east. They were a buffer.

That’s right. And the Islamic invasions of the seventh century, they couldn’t get past that choke point of Constantinople. So they had to take the long way across Africa. You know, and by the time they get to Spain and conquer Spain and into—that’s the Battle of Tours, you know—Charles Martel is able to stop them, and they’re, they’re massively overextended. You know, I think it’s a very different story if they can come in through the Black Sea.

Viking religion and Valhalla
Lex Fridman
Yeah. So rewinding back, what was the religion, the religious beliefs, the gods that the Vikings believed that we’ve mentioned a little bit of? Thor and Odin, how did they see this, this world and the universe?
Yeah. So rewinding back, what was the religion, the religious beliefs, the gods that the Vikings believed that we’ve mentioned a little bit of? Thor and Odin, how did they see this, this world and the universe?
Lars Brownworth
It’s, so the Viking gods are… I mean, they’ve been sanitized, but they’re quite terrifying. But at their basic conception of the universe is an eternal struggle between chaos and order, which chaos will eventually win. So I think the best view of cosmology is of concentric circles, with Utgard as the outer realm, and that’s where the chaos is. And those are the, that’s where the frost giants are, all the monsters that seek to destroy. The gods represent order and stability, and the monsters represent chaos, and it’s an eternal war between the two of them.

Lars Brownworth
So there are different categories of gods depending on which circle you come from. The gods don’t all like each other. They’re not… Sometimes they engage in wars. Some of the most famous gods, the Norse gods, you know, Loki or Freya, come from outside the Aesir, the main gods. So it was kind of a fluid thing.

Going to Perplexity. Vikings followed the polytheistic, ritual-heavy religion centered on a pantheon of gods and spirits with no single holy book or unified church, and practices varied a lot by region and family. And so the major gods were Odin and Thor and Freya. Odin was—his domain was war, kingship, wisdom, death. Thor was protection, thunder, fertility. Freya was love, magic, battle dead. Typical worshipers for Odin were chieftains and elite warriors and poets. Typical worshipers for Thor were farmers and “ordinary people,” and typical worshipers of Freya were women, magic practitioners, and lovers.

Yeah, yeah. I mean, I’ve heard it… I think you can break it down saying like, Odin was the elite. He’s kind of more aristocratic, right? He, he’s the god of poetry; you need to read, et cetera. Only the elite would know how to do that. A farmer wouldn’t really care about that. Wherein Thor is a more earthy god. You know, you want the waves to be less, you know, pray to Thor. I find Odin, I think, most disturbing. He’s the god of madness and the god of poetry, which, I guess those are related. But in battle, I mean, the Berserkers, probably the most famous type of Viking warriors, were considered to be Odin’s chosen warriors. They would show no pain, and they’d just run at the enemy and attack with their nails and their teeth.

Yeah. I mean, one of Odin’s names is the raven feeder. I mean, you were, by creating corpses, which ravens feed on, you are, you’re doing the work of Odin. And, you know, the Viking view of the afterlife was unique. There weren’t really punishments, not really, for doing bad things. Unless you did something really bad. Then you ended up as basically an evil spirit haunting your grave. But if you were brave, then you got taken to the house of the dead, which is Valhalla to… And you were resurrected. Every day you would fight, and whatever wounds you got would be magically healed that night. And then the next morning you’d get up and do it again. So you’re essentially practicing for Ragnarok- … the final battle, which you would lose. So I’m not sure. It seems, it’s rather pessimistic.

The sun and moon, which are being chased by monsters, by giants, will be caught and swallowed by the giants, plunging the world into eternal darkness. Essentially all the gods will die and darkness and chaos will then ensue. And then at the very end the… This is mostly from a guy named Snorri Sturluson who was living right at the end of the Viking Age and writing this. And he was, I believe, a Christian. So there’s… I think we’re fusing things here. So then there would be a new Earth and a new heaven and a new god, who’s all powerful.

Yeah, if you think of religion as a kind of technology, a social technology that stabilizes or helps guide the evolution of a society, it’s interesting to see what the Vikings came up with.

And do you ever think from a history, the grand view of history, how effective these different technologies of religion have been?
Lars Brownworth
Yeah, I mean, I think that’s certainly… I’m thinking of the Viking rituals. Hospitality is very important in a northern climate where, you know, food is scarce, winters are long and harsh. And if you don’t share your hearth with, you know, someone knocking on your door, then someone else might not share it with you and you could be facing death. So in this case hospitality becomes a core belief and- … you know, the idea was that Odin would travel incognito, knocking on people’s doors, and he would remember if you let him in or not. And if you were hospitable, he would bless you, and if you were inhospitable, he would murder you. And- … you know, I think these rituals are obviously intended for, “How do we survive this winter?”

So in this case hospitality becomes a core belief and- … you know, the idea was that Odin would travel incognito, knocking on people’s doors, and he would remember if you let him in or not. And if you were hospitable, he would bless you, and if you were inhospitable, he would murder you. And- … you know, I think these rituals are obviously intended for, “How do we survive this winter?”
Lex Fridman
Yeah, how do we effectively spread the message that hospitality is pretty? good thing, and it’s characteristic of religion. If you do a good thing, you’ll be rewarded. If you do a bad thing, you’ll be punished. And then different religions play the different ways of communicating that.

Lars Brownworth
Yeah. I mean, I think also religion gives you, it gives you a world view, right? It gives you a morality and these are core parts of society.
Yeah. I mean, I think also religion gives you, it gives you a world view, right? It gives you a morality and these are core parts of society.
Lex Fridman
And the beautiful thing about religion is it interplays with human nature and it guides humans. But then of course, human nature and humans project themselves onto the religion, sometimes they use their religion. It’s to accomplish goals in a pragmatic sense, in a political sense, in a geopolitical sense, in a military sense, in a social sense. And so there’s that dance of how religion invigorates and guides the peoples, and then how the peoples use the religion to guide the direction of the world.

And that’s certainly the history of Christianity has a big role to play in the history of Europe, in the history of the Byzantine Empire and that part of the world. And it was an incredibly effective religion once Constantine converted. It spread extremely quickly, relatively speaking, across a couple of centuries. Just to linger on the Viking views of the world and the afterlife. So we mentioned Valhalla. There’s the Norns, which are the three spirits that represent the past, the present, and the necessity. They spin the fates of all men and gods at the Roots of Yggdrasil.

Yggdrasil. So there’s a notion of like determinism and fate to the Viking life. And there’s Valhalla, there’s Hel, Niflheim. This was the destination for the vast majority of people. So if you don’t make it to Valhalla, this is where you go.

It reminds me of the Greek view of the afterlife, right? Where you essentially get amnesia and forget who you are unless someone makes a sacrifice and says your name, and only then you’ll remember it. So your- your destiny is ultimately to just become gray and fade away. So you might as well- you might as well be brave. You might as well run at that spear.

Viking explorers
Lex Fridman
I have to ask about Vikings as explorers. They were… truly one of the greatest explorers in history. What can you say to, what is it in their spirit that motivated them? I mean, they sailed, they reached North America 500 years before Columbus. They sailed obviously to England, Spain, Italy, Russia, North Africa, the Middle East, Paris, and I’m just showing here a map of the ocean routes and the river systems that they connected to and sailed. What do you think drove them to explore the unknown?

Lars Brownworth
This boggles my mind. This, like this map here, just… it messes with me because they didn’t have a compass. I mean, can you imagine shoving off from some fjord in Norway west? That’s your only—west. And there was a Viking named Naddodd. He’s actually the first Norseman to reach Iceland, though it was a total accident. But here’s the, here’s the mind-blowing part. He decides to land and explore, and he gets off and he sees two humans. They’re monks from Ireland. They got there in a canoe. You look at Ireland, look at Iceland, that’s even more impressive. They got in a canoe, a skin boat- … and they just went north because they were trying to get away from the world.

And away from sin. Yeah. You know, there’s this poem by Tennyson, “Ulysses,” my favorite poem. I think it captures the Viking spirit. The last line of it is “to strive, to seek, to find, and not to yield.” I think that’s very much like the Viking, you know, “My purpose holds, to sail beyond the baths of all the western stars until I die.” You may die, but I’m gonna do this, and I’m not gonna yield.

Vikings in North America
Lex Fridman
Let’s talk about this incredible fact of the Vikings, that Leif Ericson, who was a Viking explorer, was the first European to reach North America around the year 1000, five centuries before Columbus reached North America. Tell the story of his journey. What do we know about him?

Lars Brownworth
So let’s begin with his dad. His dad’s name is Erik the Red, who was forced to flee Norway when he was probably 10 years old because his dad had killed some people. It’s kind of hilarious. In the saga it says, “For a few killings…” Okay, I guess that’s a thing. So he went to Iceland and he got a farm in Iceland which was already starting to become overpopulated. They had cut down all the trees. There were some climate problems of deforestation and farms just blowing away, so the population was essentially beginning to crash in Iceland. And he got into a fight with his neighbor and ended up killing his neighbor, and so he was exiled from Iceland. He was exiled from the place his father had been exiled from.

What also ran in the family apparently was this streak, this courageous streak. And he had heard that there had been people… So the Norwegian Vikings, they were aiming for England, and they hit the Hebrides, which are these kind of treeless islands above Scotland, and they found they were good for refueling ’cause they’d pick up water or whatever, and then on your way to Scotland to raid. And then a Viking had missed the Hebrides and discovered Iceland, and then another Viking had aimed for Iceland, missed, and hit Greenland. And a little fun fact about Greenland, it is both north, south, east, and west of Iceland. So it’s any direction, you’re gonna hit Greenland.

Lars Brownworth
It’s hard to miss, which is not to take away anything from the extraordinary danger, the certain death of going further west. But there was this… By this time, there was this idea that, you know, enough people had become famous by sailing west into the unknown and discovering things, that I think there was a general idea of there’s more out there to the west. And so he had talked to someone who had seen Greenland and reported that there was this good land further west. And so he hired the ship’s crew of that Viking. So it’s kind of the deck was loaded, and he went to Greenland where he was able to settle two different colonies. One was called the Western Settlement in the west, and one was called the Eastern Settlement in essentially the extreme south.

And that was essentially the edges of where Viking technology could be. A cool factoid is that the Vikings practiced husbandry, raised animals, and obviously this is not an option in Greenland, although they couldn’t have known it at the time. But they brought plants with them. So, and then they were able to trade with the native Inuit for walrus blubber and things like that, and they made a go of it. But what’s obvious, you know, anyone who’s seen Greenland, there are no trees. It’s almost impossible to survive by practicing husbandry. It is impossible to survive, as it turns out, just practicing husbandry. And by this point, I think this extraordinary Viking pragmatism is beginning to be played out.

Because one of the reasons the Greenland experiment fails ultimately in 300 years is they fail to adapt. It’s clearly they should, they should focus more on fishing, on other sources than, than just raising pigs and cows. But-

Yeah. It’s the most misnamed place in the world. But in the Europe of the time, even in Iceland, the dream was to have land. I mean, land equaled wealth in Europe. And here he says there’s enough land for the taking, like anyone who wants it, which is true. It’s the largest island on earth. I mean, it’s unusable, but it should be called Iceland, Glacier Land or something. But it worked. He took 500 men with him from Iceland. It’s gotta be a significant chunk of the population, but there’s enough people, kind of land hungry, there’s no more room in Iceland. It’s too restrictive. We’re gonna go further west. So he takes 25 ships and then 14 make it, which is pretty good. And then those 14 ships with their 300 or so people start the western colony.

And then word gets back to Norway, but Norway’s 2,000 miles away, 2,000-plus miles away. So it’s, you know, contact… They’re having to get resupplied. Obviously in the first winter, all their cattle die. That’s not a great, that’s not a great start for people who practice husbandry. So they’ve got to get resupplied from Norway, but, you know, the chances of making it to Norway and back are actually not that great if you’re sailing without a compass. You’re just kind of hoping. But they do it. They do it. And the colonies survive until the 1400s where they just go silent.

So Erik is getting a little older. The Greenland settlements are becoming filled up. Erik is happy where he is. He’s been kicked out of enough places. He’s made his home here, and this is where he wants to be. But his son… They’re running out of resources. There’s no wood. You know, there’s limited food, et cetera, et cetera. And so his son proposes going west because he’s heard stories that there are other lands. So another Viking had gotten lost, aimed for Greenland and missed, and had seen something. He said he saw clouds and mountains and there’s land there. And then he had turned around. And Leif again did the same thing, he hired the man’s crew.

He asked his dad to come, his dad wouldn’t. He went with his half sister Freydis, who was a whole nother story by herself, and a bunch of other colonists, and they went, and they landed in a place. He called it Vinland because he found things that he could ferment. So, of course, the Vikings, they made wine, or a wine-like alcohol. So Leif Ericsson is, he’s landed. He doesn’t know this, but he’s landed on a new continent with essentially inexhaustible stores of food and timber and everything he needs. It’s the perfect place. Unfortunately for him, it’s also inhabited by some natives, probably the Algonquin tribe. He calls them the Skraelings, which is just Norse for screechers because he can’t understand their language.

I think there are a number of things working against them. Of course, I would like to believe there’s an alternate history where the Vikings successfully make it down, you know, maybe down to Maryland or something, and there’s an alternate history of the US and Canada here, but I think there’s a number of things working against them. The first is they stubbornly refused to give up husbandry, so they’re trying to make this work. L’Anse aux Meadows I think is where they were, in Newfoundland. It doesn’t work. The climate’s too cold. It’s not even—the grasses aren’t appropriate, you know, it’s just not gonna work and they do not adapt, number one.

The climate’s too cold. It’s not even—the grasses aren’t appropriate, you know, it’s just not gonna work and they do not adapt, number one.
Lars Brownworth
Number two, they’re 2,000-plus miles away from Norway and getting resupplied, and although they are extremely good sailors and explorers and traders, I think this is a little too far. And then thirdly is the native resistance. It’s just too incessant. They are, they are outnumbered, you know, millions to one. And the Algonquin do not want them there. It’s clear, and they’re not gonna stop attacking.

Lars Brownworth
I mean, if they could have gotten enough people from Norway, you know, or Iceland or whatever, you know, a sizable enough colony, and build some kind of defenses to fight off the incessant attacks- … then I think that’s the difference there, ’cause there certainly the resources are all there.

Mm-hmm. Or just keep staying in the water, keep going down the coast- … not necessarily camp out until, until you get further south. It is fascinating to think about that alternate history where they would have discovered America and settled there. So this is 500 years before Columbus. There’s… first of all, they could have done a lot of the stuff we think about the European nations doing, including brutality towards the natives. But there could have been a coexistence also, and some of the diseases that come with them could have done the damage that they did 500 years later. But now, it would have stabilized the populations to where the Europeans, the French, the Spanish, and so on who come, the natives would be more ready. So they would…

Europe would then encounter a sizable population of the Viking descendants and the natives to where the, the two could hold onto the land and bring a different kind of civilization there. Because ultimately Europe, with the European ways, of the Western civilization, expanded out into North America, but there could be this whole Scandinavian vibe- … that would have taken over.

Lars Brownworth
Just a hair’s breadth. My favorite museum in New York is called The Cloisters. It’s part of the Met, and in the Cloisters, there’s an ivory cross. And the ivory cross has been richly carved with Christian scenes. It was carved in England, but it’s made of walrus ivory, and they got it from the New World. And the Viking, you know, Viking traders. It represents, you know, the great arc of the northern trade. So it’s walrus ivory from the New World via Norway to England to New York. It’s a great symbol of that trade.

This whole just period of thousands of years of exploration that we no longer can do, so it’s kind of geographic exploration of the world, is fascinating. It takes true courage. It takes true wonder.

Yeah, I think the closest analog is probably Mars, right? I mean, what would it take for you to be like, “All right, I’m gonna leave and I’m gonna go to Mars”? You’re never coming back. There’s nothing there as far as you know. You know, all the accoutrements of civilization are not there. That’s the kind of courage you would have taken.

Yeah, but there’s, on top of that, with Greenland, with Iceland, with Finland, there’s just so much uncertainty, like literally what’s beyond this hill. So with Mars, everything is mapped. So it’s really you understand the full harshness of the situation.

Vikings in the East
Lex Fridman
All right. Speaking of which, going to the East. So like we mentioned, the Vikings really went all over. And one of the directions they went that ended up touching the Byzantine Empire in Constantinople, is they went East. What can you say about the 8th century journey East in the river networks that the Vikings did, the Swedish Vikings, the Varangians, as they began to explore the river systems of Russia?

Lars Brownworth
So this was the most surprising part for me when I was first thinking about writing the book and, you know, discovering where the Vikings went. I never… In a million years, it would’ve never occurred to me that the Vikings went East. But a good way to think of this is the Vikings launched themselves in whatever direction their country is facing. So Sweden goes to the East, Denmark goes down toward Germany, and Norway goes England and the New World. So there’s a Viking named Rorik who goes East and manages to set up an encampment on this lake called Staraya Ladoga.

Lars Brownworth
Yeah, and these are major river systems in the East that take you all the way down to the Black Sea and the Caspian Sea. Because the Vikings, you know, such sea-born people, they can sail up rivers. This allows them access to the caliphates in the East and to the Byzantine Empire, where they, being Vikings, immediately decide to attack the city. The Byzantines essentially set the Sea of Marmara outside of Constantinople on fire- … and burn up all the Viking ships. So then the Vikings decide, “Okay, we can’t, we can’t take Constantinople, so we might as well join ’em if we can’t beat ’em.” And they end up as probably the most famous guard in Byzantine history, the Varangian Guard. Varangian means the men of the oath.

Lars Brownworth
Or the men who’ve sworn an oath. This is kind of an analog of the Praetorian Guard in Ancient Rome. They were famously loyal to the throne, but not necessarily to the person sitting on the throne. They’re major power players. The last of the great Byzantine emperors, Basil the Bulgar-Slayer forms them in the late 900s. And they’re there with the history all the way up until the end of it. In fact, many of our famous Vikings, Harald Hardrada, serve in the Varangian Guard. If you go to Constantinople today, inside the Church of the Hagia Sophia, on the second floor there’s a marble balcony, and on the railings, you can find Norse runes that are carved in by Varangian Guards who were bored during a particularly long sermon, in a language they didn’t understand, but they had to stand there.

But this whole… You fast-forwarded the story, we should mention that Staraya Ladoga in 753 AD is when it was established, opening the connection to the two rivers, and they began trading on the rivers and establishing more stable states along the rivers, including the Kievan Rus in 862, 882, where the Varangians, so it’s the Swedish Vikings, they took Novgorod, they took Kiev, and they established the Kievan Rus there. And that is what led to the connection to the Byzantine Empire, where they started to… Again, the Vikings went from being Vikings. They go through this process of trading and then establishing a state, now they’re doing treaties of different kinds, and they’re also waging or trying to wage war.

Lars Brownworth
We don’t really know what it was, Greek Fire. It was a form of napalm, obviously. We have the ingredients what made it up, naphtha and oil and things like that. But it was this very flammable material that would ignite on contact. So the Byzantines would fill it into clay pots and then throw the clay pots. As soon as it’s exposed to oxygen, it would start burning. They also had siphons. They would carry, like, flamethrowers on their back and they would just spray it at enemies. And the- the real devious thing about it is that if you launch this clay pot at a ship and the material, you know, pooled across the wood and then dripped off into the water, being oil, it would float on top of the water and continue to burn.

So that if you were a sailor and you jumped off the ship ’cause it’s on fire and jumped into this oil patch that’s on fire, you’d be coated with it and you’d burn underneath the water. It was a horrible way to go. So this was a state secret, closely guarded secret. So closely guarded—it remains a mystery to this day of what exactly it was.

Yeah. But it, in the 944 attack on Constantinople, I mean the Vikings are coming on their ships. They brought these ships from Sweden. I mean that’s crazy. They’re in the Black Sea. They’ve sailed and they kind of swarm at the Byzantines. The Byzantines launch a bunch of decrepit old ships toward them that have Greek fire on them, and that turns the tide. But the Byzantine emperor so appreciates the strength of these horrifying Vikings that he forms a bodyguard of them.

Yeah, that’s right. ‘Cause not only do you get paid very, you’re compensated very well obviously for defending the emperor, particularly if you do a good job, but you also have opportunities ’cause the emperor sends you, “Let’s go attack, you know, this tribe,” and you get to keep whatever you take. So there’s tremendous amounts of war profiteering you can accomplish. And the other great river system, the Volga, that brings you to the great enemy of the Byzantines, the Abbasid Caliphate. And they had a lot of trading links with the north. So you get things like fur and amber, lots of slaves from the Islamic world going up. You even have in a Swedish coin hoard, there’s a Buddha that’s been found. I mean… it’s Sweden.

Like there’s no… That doesn’t make sense unless you’re a Viking. You know, he’s… That also added tremendously to the terror that the Vikings brought, because I mean you should probably be a little careful with absolute statements here, but I can’t think of a major European city that’s not on a river. Which meant now with the Vikings, ’cause they could travel up, you know, rivers, the shallow rivers and then carry their boats whenever, everything was on the table now, even hundreds of miles inland is on the table.

We’ve talked about this transition in several different contexts, but you’ve written about this. It’s really interesting. Is the Vikings, like Ragnar, going from this mode of sea kings with no territory to the mode of land kings? So you have like somebody like Harald Bluetooth, 10th century Viking king of Denmark, you go from being these grand explorers that are free to being state builders. Was this always inevitable for all of these Vikings? Could we speak to the different transitions, maybe in England?

I think in one way, it’s inevitable. There’s so many examples of destroyers who just wreck civilizations. The builders are much more rare, you know? So I think it’s one of the reasons I think Augustus is a much more interesting person than Julius Caesar is. Augustus was a builder, and I like to see that. I like to see not just can you pull down, but can you build up? You know, just to take Ireland for example, Dublin, Limerick, almost every major city in Ireland was founded by the Vikings. So I don’t think it’s just a given that it would have happened. I think there’s something about the Vikings, and it’s probably tied to their pragmatism, their—like this pragmatic streak of, “We’re gonna use whatever. Oh, this system of king works.

And so people are telling him all the time how wonderful he is, and he takes his whole court down to the seashore and orders his, his courtiers to carry him on his throne into the water, and then he commands the seas to stop, the waves to stop and to retreat.

And they don’t, obviously, and everyone thinks he’s a little… But his point is that, “Y’all are saying how great I am. I have no control.” I mean, this is his active humility to kind of embarrass… “I have no control over anything. Stop telling me I’m the greatest thing since sliced bread.”

I like the leaders, and there’s a few of them in history that rise to the very top, and they’re still able to maintain humility. Marcus Aurelius in the Roman Empire is an example that, you know, reading Meditations is also just an insight into the mind of a man who’s to himself—’cause Meditations is not supposed to be work that’s published. It’s just a diary. To himself, he’s deeply humbled. And- … and one of the most powerful humans in history- … is still humble.

So in the other part of the world, you’ve written a book and you did an—a legendary podcast series on The Byzantine Empire, the East Roman Empire, AKA, The Roman Empire. Well, let me actually just as a tangent of a tangent ask you about the podcast. So you’re—you created what is widely considered to be the first history podcast. This is before Dan Carlin, before all the amazing podcasts we all know and love. So the podcast series of course is The Twelve Byzantine Rulers: The History of the Byzantine Empire. What motivated you to explore this medium of podcasting? What… In—in the early, this must’ve been 2005, something like this.

There was one particular professor. His name is Bob Brier, and he was—he’s an Egyptologist, lives on Long Island where I’m from, and he—I mean, it’s a massive thing. It’s like 24 hours- of lectures about the entire history of Egypt, and it was fascinating, ’cause he’s such a good storyteller. And I was reading… As a kid I could never figure out if I liked the medieval period better or the Roman period better. I was constantly going back and forth, and I stumbled across a book which referred to the medieval Roman Empire, and it was a bit like discovering your favorite TV show had 12 extra seasons you didn’t know about.

And they were just as good. So I… It really was a labor of love. I would not shut up about The Byzantine Empire. So my older brother, we would go on walks together and I would be like, “And then Justinian, you know, da, da, da.” And he stopped me, he said, “I have no idea what you’re talking about. I have no idea, like, I need a framework. Give me a framework for this.” So I went home and I recorded myself giving a framework, which turned out to be episode one, but I think I did it in a British accent, a really bad British accent.

I was just messing around. And I gave him the… Luckily, I did it in my regular voice as well as this goofy accent, and I gave it to him and then I forgot about it. And that summer I was on a dig in Petra excavating the Temple of the Winged Lions, which was like a dream come true for me. And I get this email from my brother and he said, “Oh, I just submitted it as a podcast.” So he had to tell me what that was. But I was going for, to the extent that I had put thought into it, I was going for kind of a longer form lecture Great Courses series on the Byzantines. And then a bunch of people started emailing me saying, “When’s episode two coming out?” Oh, okay. So I guess there has to be an episode two. And then the thing kinda snowballed from there. I had no idea what I was doing.

But like looking back now, what do you think about that medium? Why do you think it connected so much to people? Because you’ve also written several amazing books.

Just looking back in a retrospective kind of way, because that from there blew up an entire industry of incredible other history podcasts and podcasts in general.

Yeah, I’ve been… That’s a great question. I’ve been trying to think for the past 20 years, like why it’s such a niche field, right? Why would people be interested in it? I think number one, it’s a great story. And people are people, and we haven’t changed much, which is one of the reasons why it’s accessible, because it’s very… These are people you could meet today. But I think podcasting in general, because there’s such a low bar to get in, or there was at the time. I mean, there’s nobody else, so just by virtue of being first, you know, it attracted attention. Whatever its merits, being first was the strongest one.

Byzantine Empire
Lex Fridman
And the Byzantine Empire’s an interesting one. I don’t understand maybe… And you articulated this well, but it doesn’t get like the love that it maybe deserves in history. I think the framing of the book you wrote on the topic is the reason we have Western civilization as we know, or European-based Western civilization. In a sense because you have… They… Let’s see, maybe you can articulate the different ways they connected the thread, but one of them is they preserved the knowledge when the West was—when Europe was going through a dark period; they protected Europe in all those ways.

And then eventually they jumpstart the Renaissance, ’cause people are… Constantinople’s gonna fall. It’s inevitable. It’s surrounded by hostile powers, and so they start migrating to Italy. Just at the moment Italy is receptive to its Greco-Roman past. Greek had died out in the West actually as early as the time of Justinian in the 500s, 560s. They needed… If you wanted to travel between the eastern and western parts of the empire, you needed guidebooks with helpful Latin or Greek phrases. So Latin had died out in the East and Greek had died out in the West by the 14th century, so you needed Byzantine teachers to be able to read Plato and Aristotle.

I think the Hagia Sophia is that for the Byzantine Empire. I mean, to go in it today is still the closest you can come to the fifth century. You know, and it peeled back the imperial splendor of what it must’ve been like. You know, you can still see it. You can smell it. You can feel it. Like, it’s there.

Well, you know, they—as you know, they’re very strict as to guides. They want to promote the local economy, so you have to have a local guide. You can’t go in there and look like you’re being a tour guide without a license. You have 15 different organizations. So we went there early, the hour it opened, and we had the entire cathedral to ourselves. And so we went around and my brother’s holding this camera and I’m, you know, goofily pointing things out. And one of the guards noticed us, and, you know, we had to remove ourselves from the building.

And so one of the things, I mean Justinian was a critical person in this too. He overhauled the Roman law. The legal system, the law… First of all, the Roman Empire in general, the East Roman Empire propagated it. They believed in the law. They held onto the law. And that’s many of the legal ideas we take for granted is grounded in everything developed in the Roman Empire and stabilizing the Roman Empire, so they carried that flag forward.

Yeah. I mean, outside of Great Britain, all European legal systems are based on, ultimately based on the Code of Justinian, and then weirdly, because of the French connections, the State of Louisiana.

Why do you think the—the Western Roman Empire and then the Eastern Roman Empire collapsed? Just looking at the grand picture of the history of the Roman Empire, it’s 2,200 years starting from the kingdom to the republic… and to the imperial period, to the East Roman Empire period. Why do societies rise and fall?

Lars Brownworth
That’s a really interesting question, and there are probably as many answers as there are different kingdoms. But just the Roman Empire. My take on it is that the collapse really starts at the end of the reign of Basil II. So the year is 1025. Basil is the last monarch of the Macedonian dynasty, which had seen the empire become the most powerful state in the Mediterranean, much more powerful and advanced than its Muslim or Christian neighbors. He had expanded the empire essentially as large as it was going to be after Justinian. It was wealthy, it was glittering, it was educated. I mean, courtiers had to memorize the works of Plato by heart.

But when he died, the court, which had been this magnificent court, this bureaucracy which had been running the empire, and which is vital to the workings of the empire, they convinced themselves that they could run the empire, they didn’t actually need the emperor. And so they specifically selected weak rulers, and then that led directly to the disastrous Battle of Manzikert in 1071, where the Turks enter the story and defeat, destroy the Roman army under Romanos Diogenes, who’s attempting to break free of the bureaucratic constraints.

So once they’ve lost the heartland, they’ve lost their source of troops, they’ve lost their source of taxation, they’ve lost their source of food. At this point it’s impossible to recover, and the Crusades are an attempt, the First Crusade anyway is an attempt by the Eastern Emperor Alexius to recover Asia Minor, more than Jerusalem. He wants to recover Asia Minor, and obviously it doesn’t work out. So I think at that point, it’s on a trajectory that can only end in collapse. And I think that’s, you can see that same kind of thing in the Viking world that we talked about, this stultifying, bureaucratic, this inflexibility.

Yeah, that’s the question, isn’t it? I… The short answer is I subscribe to the great man or great woman theory. I think there’s moments—I can’t imagine the Protestant Reformation. I don’t think you can just swap out Martin Luther and have a Protestant Reformation. I don’t think you can swap out Augustus and have the Roman Empire. I mean, there are… I don’t think you can swap out Genghis—and so on and so forth. I think ultimately these impersonal forces are insufficient for explaining, because we are people. We are humans. We are, you know, everything is kind of a relational thing. And but at the same time, you know, the moment needs the man, but the man also needs the moment, you know?

Some of it is timing, some of it is the environment- … the system around it. But yeah, I’ve just seen so many incredible humans that persevere through things that would break basically everybody. And they, the power of the belief they have. We were talking offline about Napoleon. Here’s a guy who was a student of all the great military generals of the past. Extremely competent in being able to micromanage every aspect of military affairs of a nation, but also extremely confident in his vision of the world and ability to conquer anyone. And you have the same thing with Genghis Khan. This boy that came from nothing. Everything was taken away. He united all of Mongolia, and then conquered most of the known world to them, including eventually China.

Go at it.
Go at it.
Lex Fridman
… what lessons from all the things we’ve talked about, the exploration of the Vikings? What lessons do you learn from Vikings?

Lex Fridman
By the way, I should mention one thing. It’s a very practical lesson that we didn’t talk about that you taught me is the, the Vikings were, like, groomed themselves.

Lars Brownworth
Oh yeah.
Oh yeah.
Lex Fridman
They were like clean. This is so very surprising to me. That they like washed themselves and then both the men and the women- … really took care of themselves. You don’t often think about that.

Lars Brownworth
There was this whole… Like, the Vikings, everyone at this… Everyone has this very clear picture of what a Viking looked like- … and also has no idea what a Viking looked like somehow at the same time. Like, almost everything about them is wrong- … that we think of. You know, almost everything about them is wrong. They didn’t wear horned helmets. They, their hair probably was blonde disproportionately, but that was more because they used lye to dye it because it would kill the lice. And then they would take baths on a more regular basis than… I mean, this depended on where you were. So in England, for example, they were mocked as being soft, which always blows my mind. Like, really? You’re gonna mock the Vikings for being soft? Because they took too many baths.

But then in the Muslim East, one Muslim traveler writes that they were God’s filthiest creatures because of their habits of kind of disgusting shared bathing.

Lex Fridman
Oh, that aspect of it.

Lars Brownworth
That, yeah.
That, yeah.
Lex Fridman
Yeah. So, it’s not that they didn’t bathe, they bathed a little too much and together.
Yeah. So, it’s not that they didn’t bathe, they bathed a little too much and together.
Lars Brownworth
They bathed, but they also like would brush their teeth- … using like recycled… Like, they would then spit into a cup and pass it to the next guy.

I read that… This is, this could be propaganda, but I read that in England there was worry that the Vikings were a bit too attractive to the women of England because of how much the Vikings took care of themselves in terms of grooming.

Is there something bigger about the exploration about the leaps into the unknown?
Is there something bigger about the exploration about the leaps into the unknown?
Lars Brownworth
Yeah, I think a couple of years ago, there were all these debates about statues. Make sure we pull these statues down. This person did a bad thing, let’s pull these statues. You know, and I always thought they were kind of silly, too. I mean, I understand the point, but… Like, we don’t… When you have a statue of Christopher Columbus, for example, you’re not glorifying every single thing the man ever did and all the bad stuff that comes from this or that. You’re honoring something about him, like the spirit it takes to cross an ocean not knowing what’s on the other side, and that’s that spirit of exploration. I think with the Vikings, it’s the same. There’s this way you approach the world, this fearless, pragmatic approach.

I think as an American too, it’s the ultimate rags to riches. It’s the myth we tell ourself. You know, the man who starts with nothing and ends up as a sea king, well respected and sung about by poets. I mean, that’s it right there. You know, this is… And when you’re a society and you stop doing this, you run into trouble as well.

What about the, the Byzantine Empire? What lessons do you draw from them?

Lex Fridman
1000-year history.
1000-year history.
Lars Brownworth
1000-year history, and it’s also what I think is so cool about the Byzantines is that in the ways that they are like us and the way that they are unlike us. In some ways, they’re very analogous to the United States. The kind of the polyglot nature of their inhabitants, you know, the, their roots, the Greco-Roman, Judeo-Christian roots. And yet it was a place of incredible alien things as well. Men sitting on top of pillars. You know, a king, an incredibly hierarchical system which abhorred democracy. So I think it’s a way, it’s a way we… It’s a route we could have taken…. And it’s the way they handled things. Immigration, inflation, war, peace, diplomacy. I think there are, there are lessons there for us.

Yeah. Yeah, I think from the Vikings, the lessons are a bit more poetic. The lessons from the Byzantine Empire is like quite literal, like how to run a government, how to run the law, how to-
Lars Brownworth
Yeah. How to build a stable society. And honestly, like you can count on the fingers of one hand, states that have lasted a thousand years, right? Byzantium and Venice, I think. And Venice was an offshoot of the Byzantines. Like that’s a gov— for a government to last a thousand years is a rare thing. Like, we should be taking a look at this. Like how? And how much of that is due to Augustus? Can we give him any credit for this? He built the system.

Lex Fridman
Yeah. But there was a lot, like you mentioned a lot of people along the way from Constantine to Justinian, the Basils. There’s so many emperors along the way that revolutionized and then restabilized the empire after it was almost falling apart.
Yeah. But there was a lot, like you mentioned a lot of people along the way from Constantine to Justinian, the Basils. There’s so many emperors along the way that revolutionized and then restabilized the empire after it was almost falling apart.
Lars Brownworth
Oh, yeah. You know what else too though? Like what happens to a human when you give that human essentially absolute power? ‘Cause the Byzantine emperor stood halfway there. I mean, he was more autocratic than anything other than, I don’t know, the pope that we have in the modern world. What happens when you give someone that level of power? Like, I love Justinian, but I wouldn’t have liked to know him. You know, I wouldn’t like to be one of his subjects. I love Basil I, but the man was a bloodthirsty tyrant. Like, I think it shows you what happened. What is it? Lord Acton: “Absolute power corrupts, and absolute power corrupts absolutely.” Like that’s quite clear throughout Byzantine histories, and it’s a long, a long list.

And it’s— I mean, this is the project for the 21st century, the 20th and the 21st centuries post-Industrial Revolution, post the computer technological revolution, post nuclear weapons discovery. How do we construct societies that last like the Byzantine Empire did a thousand years? It’s just like a new challenge for us. There’s gonna be history books written about us ’cause like nuclear weapons, you know, 80 years ago, it’s like Greek fire that you can apply to the entirety of human civilization. And, and so- … that, there’s gonna be good history books, and I hope there’s gonna be these stories about the American empire, about the rest that sound similar to Byzantium Empire versus the Viking age. It only lasted-

Lars Brownworth
During grad school, I was reading Frederick Douglass’ autobiography, and he said, “I could sit with Plato and Cicero, and they would not flinch.” You know, by which he meant that the great conversation was for everyone, no matter what your skin color, no matter what your level of income, and even no matter your intelligence, you know? And I think that’s actually what, that’s why history comes alive for me, is because these are not alien people. You, you had asked how similar are ancient people to us psychologically.

Lars Brownworth
You know, and what their goals were for li- And I think the short answer is they were identical to us, which is why we can understand them. It’s why you should read things. It’s why you should read the Meditations because this is not just some dry whatever talking to himself in a culture that you cannot understand and can never recreate. It’s a human talking about being human, you know? And I think human nature has not changed, and I don’t think human nature will change. So we are flawed and broken, and we’re… that’s, that’s the human condition. We’re gonna be flawed and broken. So I don’t think… I actually think that’s the great, that’s the great question of history. If you wanna understand history, you have to know about human nature. What is our human nature?

If you think it’s a blank slate and we can kind of educate ourselves to a utopia or, you know, like the Marxists said, then okay. Hasn’t really worked out, but okay. If you believe we’re basically bad, there’s a whole set of things that come with that. If you believe we’re basically good, there’s a whole set of… right? So, you won’t learn the appropriate lesson if you misdiagnose human nature.

Yeah. I think the diagnosis that you’re kinda hinting at is, is seemingly the most accurate one, which is we’re flawed. A mix of good, a mix of evil, capacity for both.

That’s right. That’s right. I mean, I have to teach my kids to be kind. I don’t have to teach my kids to be unkind. I mean, one of those is natural, and one is not. I think my kids can become kind, you know?

Well, what is it? That line of, “All of us are in the gutter, but some of us are looking up at the stars.” And so you gotta teach as many of us to look up at the stars and dream. Because once you allow yourself to dream of a better world, you try, you try. Like the Vikings did, go out there. Don’t… try to not to murder your neighbor, but if you do, all of us have, of course.

Extreme co-design and rack-scale engineering
Lex Fridman
You’ve propelled NVIDIA into a new era in AI, moving beyond his focus on chip scale design to now rack scale design.
You’ve propelled NVIDIA into a new era in AI, moving beyond his focus on chip scale design to now rack scale design.
Lex Fridman
And I think it’s fair to say that winning for NVIDIA for a long time used to be about building the best GPU possible, and you still do, but now you’ve expanded that to extreme co-design of GPU, CPU memory, networking, storage, power cooling, software, the rack itself, the pod that you’ve announced, and even the data center. So let’s talk about extreme co-design. What is the hardest part of co-designing a system with that many complex components and design variables?

So let’s talk about extreme co-design. What is the hardest part of co-designing a system with that many complex components and design variables?
Jensen Huang
Yeah, thanks for that question. So first of all, the reason why extreme co-design is necessary is because the problem no longer fits inside one computer to be accelerated by one GPU. The problem that you’re trying to solve is you would like to go faster than the number of computers that you add. So you added 10,000 computers, but you would like it to go a million times faster. Then all of a sudden you have to take the algorithm, you have to break up the algorithm, you have to refactor it, you have to shard the pipeline, you have to shard the data, you have to shard the model. Now all of a sudden when you distribute the problem this way, not just scaling up the problem, but you’re distributing the problem, then everything gets in the way.

Now all of a sudden when you distribute the problem this way, not just scaling up the problem, but you’re distributing the problem, then everything gets in the way.
Jensen Huang
This is the Amdahl’s law problem where the amount of speed up you have for something depends on how much of the total workload it is. And so if computation represents 50% of the problem, and I sped up computation infinitely like a million times, you know, I only sped up the total workload by a factor of two. Now all of a sudden, not only do you have to distribute a computation, you have to shard the pipeline somehow. You also have to solve the networking problem because you’ve got all of these computers are all connected together. And so distributed computing at the scale that we do, the CPU is a problem, the GPU is a problem, the networking is a problem, the switching is a problem. And distributing the workload across all these computers is a problem.

Jensen Huang
It’s just a massively complex computer science problem. And so we just gotta bring every technology to bear. Otherwise, we scale up linearly or we scale up based on the capabilities of Moore’s Law, which has largely slowed because Dennard scaling has slowed.

How Jensen runs NVIDIA
Lex Fridman
I’m sure there’s trade-offs there. Plus you have a complete disparate disciplines here. I’m sure you have specialists in each one of these high bandwidth memory, the network and the NVLink, the NICs, the optics and the copper that you’re doing, the power delivery, the cooling, all of that. I mean, there’s like world experts in each of those. How do you get ’em in a room together to figure out-

Jensen Huang
That’s why my staff is so large. Yeah.
That’s why my staff is so large. Yeah.
Lex Fridman
What’s the pro- can you take me through the process of the specialists and the generalists? Like how do you put together the rack when you know the s- the set of things you have to shove into a rack together? Like what does that process look like of designing it all together?

Jensen Huang
Yeah. There’s the first question, which is: what is extreme co-design? We’re optimizing across the entire stack of software from architectures to chips, to systems, to system software, to the algorithms, to the applications. That’s one layer. The second thing that you and I just talked about goes beyond CPUs and GPUs and networking chips and scale up switches and scale out switches. And then of course, you gotta include power and cooling and all of that because all these computers are extremely power hungry. They do a lot of work and they’re very energy efficient, but they in aggregate still consume a lot of power. And so that’s one. The first question is, what is it?
Yeah. There’s the first question, which is: what is extreme co-design?

The second question is, why is it, and we just spoke about the reason, you know you want to distribute the workload so that you can exceed the benefit of just increasing the number of computers. And the, and then the third question is, how is it, how do you do it?

And, and that’s the, that’s kind of the miracle of this company. You know, when you’re designing a computer, you have to have an operating system of computers. When you’re designing a company, you should first think about what is it that you want the company to produce. You know, I see a lot of companies’ organization charts, and they all look the same. Hamburger organization charts, soft organization charts, and car company organization charts. They all look the same. And it doesn’t make any sense to me. You know, the goal of a comp- of a company is to be the machinery, the mechanism, the system that produces the output. And that output is the product that we like to create. It is also designed, the architecture of the company should reflect the environment by which it exists.

Exactly. And whoever wants to tune out, tune out. You know what I’m saying? And the reason for that is because the people who are on the staff, they know when to pay attention. There’s supposed… You know, it’s something they could have contributed to, they didn’t contribute to, “I’m going to call them out.” You know? And so, “Hey, come on, let’s get in here.”

So, as you mentioned, NVIDIA is this company that’s adapting to the environment. So, which point can you say, did the environment change and began adapting sort of secretly- … in the early days from GPU for gaming, maybe the early deep learning revolution to we’re now going to start thinking of it as an AI factory? What does NVIDIA do? It produces AI; let’s build a factory that makes AI.

I could reason through that systematically. We started out as an accelerator company. But the problem with accelerators is that the application domain’s too narrow. It has the benefit of being incredibly optimized for the job. You know, any specialist has that benefit. The problem with intense specialization is that, of course, your market reach is narrower, but that’s even fine. The problem is, the market size also dictates your R&D capacity. And your R&D capacity ultimately dictates the influence and impact that you can possibly have in computing. And so, when we first started out as an accelerator, very specific accelerator, we always knew that was going to be our first step.

We had to find a way to become accelerated computing. But the problem is, when you become a computing company, it’s too general purpose and it takes away from your specialization. The tur- I connected two words that actually have fundamental tension. The better computing company we become, the worse we became as a specialist. The more of a specialist, the less capacity we have to do overall computing. And so, that… And I connected those two words together on purpose, that the company has to find that really narrow path, step by step by step, to expand our aperture of computing, but not give up on the most important specialization that we had. Okay, so the first step that we took beyond acceleration was we invented a programmable pixel shader.

So, that was the first step towards programmability. It was our first journey towards moving into the world of computing. The second thing that we did was we created, we put FP32 into our shaders. That FP32 step, IEEE-compatible FP32, was a huge step in the direction of computing. It was the reason why all of the people who were working on stream processors and, you know, other types of data flow processors discovered us. And they said, “Hey, all of a sudden, you know, we might be able to use this GPU that’s incredibly computationally intensive, and it’s now, you know, compliant with IEEE.”

I can take my software that I was writing, you know, previously on CPUs, and I can see about using the GPU for that. And which led us to create, put C on top of FP32, what’s called, we call Cg. The Cg path took us to eventually CUDA. CUDA, step by step by step we… Well, the putting CUDA on GeForce, that was a strategic decision that was very, very hard to do, because it cost the company enormous amounts of our profits, and we couldn’t afford it at the time. But we did it anyway because we wanted to be a computing company. A computing company has a computing architecture. A computing architecture has to be compatible across all of the chips that we build.

For people who don’t know, it turned out to be, spoiler alert, one of the most incredibly brilliant decisions ever made by a company. So, CUDA turned out to be an incredible foundation for computation in this AI infrastructure world. So, so- … just setting the context. It turned out to be a good decision.

Jensen Huang
Yeah, it turned out to have been a good decision. I think the… So, here’s the way it went. So, we invented this thing called CUDA, and it expanded the aperture of applications that we can accelerate with our accelerator. The question is, how do we attract developers to CUDA? Because a computing platform is all about developers. And developers don’t come to a computing platform just because, you know, it could perform something interesting. They come to a computing platform because the install base is large. Because a developer, like anybody else, wants to develop software that reaches a lot of people. So, the install base is, in fact, the single most important part of an architecture. The architecture could attract enormous amounts of criticism.

For example, no architecture has ever attracted more criticism than the x86… you know, as a less than elegant architecture, but yet it is the defining architecture of today. It gives you an example that in fact so many RISC architectures which were beautifully architected, incredibly well-designed by some of the brightest computer scientists in the world, largely failed. And so I’ve given you two examples where one is, you know, one is elegant, the other one’s barely aesthetic, and so yet x86 survived and the reason for-

Install base is everything.

Jensen Huang
Install base defines an architecture. Not… Everything else is secondary, okay? And so there were other architectures at the time. CUDA came out, OpenCL was here. There were… You know, there’s several other competing architectures. But the thing that… The decision that we made that was good was we said, “Hey, look, ultimately it’s about install base and what is the best way we could get a new computing architecture into the world?” By that timeframe, GeForce had become successful.

We were already selling millions and millions of GeForce GPUs a year, and we said, “You know, we, we ought to put CUDA on GeForce and put it into every single PC whether customers use it or not, and use it as a starting point of cultivating our install base.” Meanwhile, we’ll go and attract developers, and we went to universities and wrote books and taught classes and put CUDA everywhere. And eventually people discover… And at the time, the PC was the primary computing vehicle. There was no cloud, and we could put a supercomputer in the hands of every researcher in school, every scientist, you know, every engineering school, every… or every student in school, and eventually something amazing will happen.

Well, the problem was CUDA increased our cost of that GPU, which is a consumer product, so tremendously, it completely consumed all of the company’s gross profit dollars. And so at the time, the company was probably, you know, worth, I don’t know, at the time, eight… Was it like $8 billion or something? Like six, $7 billion or something like that. After we launched CUDA, I recognized that it was going to add so much cost, but it was something we believed in. You know, our market cap went down to like one and a half billion dollars. And so we were down there for a while and we clawed our way back slowly, but we carried CUDA on GeForce. I always say that NVIDIA is the house that GeForce built, because it was GeForce that took CUDA out to everybody.

Researchers, scientists, they discovered CUDA on GeForce because they were all, you know… Many of ’em were gamers. Many of them built their own PCs anyways. In a university lab, many of them built clusters themselves, you know, using PC components. And, and so that, you know, that’s kind of how we got going.

Well I had to make it clear to the board what we’re trying to do, and the management team knew our gross margins were gonna get crushed. So you could imagine a world where GeForce would carry the burden of CUDA and none of the gamers would appreciate it and none of the gamers would pay for it. You know, they only pay certain price and it doesn’t matter what your cost is. And so the… You know, we increased our cost by 50% and that consumed… And we were a 35% gross margin company, and so it was a… It was quite a difficult decision to make. But you could imagine that someday this would go into workstations and it would go into supercomputers and in those segments, maybe we can capture more margin.

Well, first of all, I’m informed by a lot of curiosity. At some point, there’s a reasoning system that convinces me so clearly this outcome will happen. That this will happen. And so I believe it in my mind, and when I believe it in my mind, you know how it is. You manifest a future and that future is so convincing, there’s no way it won’t happen.

Oftentimes, I’ve already made up my mind, but I’ll take every possible opportunity—external information, new insights, new discoveries, new engineering revelations, new milestones developed—I’ll take those opportunities and I’ll use it to shape everybody else’s belief system.

Every organization and everybody, many of the people might have heard everything. Most of the company hears, of course, pieces of it. And on the day that I announce it, everybody’s kind of bought in to many pieces of it.

And, and, and so by the time that I announce something, like for example, we just announ- we just announced Grok. We’ve been late… I’ve been talking about the stepping stones for two and a half years.

We don’t build computers. We actually don’t build clouds. We don’t… As it turns out, we’re a computing platform company. And so nobody can buy anything from us. That’s the weird thing. You know, we vertically design, vertically integrate to design and optimize, but then we open up the entire platform at every single layer to be integrated into other companies’ products and services and clouds and supercomputers and OEM computers, and so the amazing thing is, I can’t do what I do without having convinced them first.

You know, we vertically design, vertically integrate to design and optimize, but then we open up the entire platform at every single layer to be integrated into other companies’ products and services and clouds and supercomputers and OEM computers, and so the amazing thing is, I can’t do what I do without having convinced them first. And so most of GTC is about manifesting a future that by the time that we… My product is ready, they’re going, “What took you so long?”
AI scaling laws
Lex Fridman
Yeah. So one of the things you’ve been a believer for a long time is scaling laws, broadly defined. So are you still a believer in the scaling laws?
Yeah. So one of the things you’ve been a believer for a long time is scaling laws, broadly defined. So are you still a believer in the scaling laws?
Jensen Huang
Yeah, yeah. Yeah, we have more scaling laws now.
Yeah, yeah. Yeah, we have more scaling laws now.
Lex Fridman
So I think you’ve outlined four of them with pre-training, post-training, test time, and agentic scaling. What do you think, when you think about the future, deep future and the near-term future, what are the blockers that you’re most concerned about that keep you up at night that you have to overcome in order to keep scaling?

What do you think, when you think about the future, deep future and the near-term future, what are the blockers that you’re most concerned about that keep you up at night that you have to overcome in order to keep scaling?
Jensen Huang
Well, we can go back and reflect on what people thought were blockers. So in the beginning, we were… The pre-training scaling law. You know, people thought, rightfully so, that the amount of data that we have, high-quality data that we have, will limit the intelligence that we achieve. And that scaling law was an important, very important scaling law. The larger the model, the correspondingly more data results in a smarter AI. And so that was pre-training. And Ilya Sutskever said, “We’re out of data,” or something like that. “Pre-training is over,” or something like that. The industry panicked, you know, that this is the end of AI. And of course, that’s obviously not true.

Jensen Huang
We’re gonna keep on scaling the amount of data that we have to train with. A lot of that data is probably gonna be synthetic, and that also confused people, you know? And what people don’t realize is they’ve kind of forgotten that most of the data that we are training, that we teach each other with, inform each other with, is synthetic. You know, it’s synthetic because it didn’t come out of nature. You created it. I’m consuming it. I modify it, augment it, I regenerate it, somebody else consumes it. And so we’ve now reached a level where AI is able to take ground truth, augment it… Enhance it, synthetically generate an enormous amount of data.

Jensen Huang
And that part of post-training continues to scale, and so the amount of data that we could use that is human generated will be smaller, and smaller, and smaller. The amount of data that we use to train models is going to continue to scale to the point where we’re no longer limited… Training is no longer limited by… Data is now limited by compute. And the reason for that is most of the data is synthetic. Then the next phase is test time, and I still remember people telling me that, “Inference? Oh, yeah, that’s easy. Pre-training, that’s hard.” These are giant systems that people are talking about. Inference must be easy. And so inference chips are gonna be little tiny chips, and-

… you know, they’re not, they’re not like NVIDIA’s chips. Oh, those are gonna be complicated and expensive, and, you know, we could make… And this is- … in, in the future, inference is gonna be the biggest market, and it’s gonna be easy, and we’re gonna commoditize it. You know, everybody can build their own chips. And, and that was always illogical to me because inference is thinking, and I think thinking is hard. Thinking is way harder than reading.

Jensen Huang
You know, pre-training is just memorization and generalization, you know, and looking for patterns in relationships. You’re reading and reading, versus thinking, reasoning, solving problems, taking unexplored experiences, new experiences, and breaking it down into… Decomposing it into, you know, solvable pieces that we then go off, either through first principle reasoning, or, you know, through previous examples, prior experiences. You know, or just exploration and search and, you know, trying different things. And that whole process of test time scaling inference, is really about thinking. And it’s about reasoning, it’s about planning, it’s about search, it’s about…

And it’s about reasoning, it’s about planning, it’s about search, it’s about…
Jensen Huang
And so how could that possibly be compute light? And we were absolutely right about that. You know, so test time scaling is intensely compute intensive. Then the question is, okay, now we’re at inference and we’re at test time scaling, what’s beyond that? Well, obviously we have now created, you know, one agentic person, and that one agentic person has a large language model that we’ve now developed. But during test time, that agentic system goes off and does research and bangs on databases, and it goes out and, you know, uses tools, and one of the most important things it does is spins off and spawns off a whole bunch of sub-agents. Which means we’re now creating large teams. It’s so much easier to scale NVIDIA by hiring more employees than it is to scale myself.

Jensen Huang
And so the next scaling law is the agentic scaling law. It’s kind of like multiplying AI. Multiplying AI, we could spin off agents as fast as you want to spin off agents. And so, you know, I… You know, I have four scaling laws. And as we use the agentic systems, they’re gonna create a lot more data, they’re gonna create a lot of experiences. Some of it we’re gonna say, “Wow, this is really good. We ought to memorize this.”

Jensen Huang
That data set then comes all the way back to pre-training. We memorize and generalize it. We then refine it and fine-tune it back into post-training. Then we enhance it even more with test time, you know, and the agentic systems, you know, put it out to the industry. And so this loop, this cycle, is gonna go on and on and on. It kinda comes down to basically intelligence is gonna scale by one thing, and that’s compute.

For example, these AI model architectures are being invented about once every six months. Right? And system architectures and hardware architectures kind of every three years. And so you need to anticipate what likely is going to happen, you know, two, three years from now. And there’s a couple ways that you could do that. First of all, we could do research internally ourselves, and that’s one of the reasons why we have basic research, we have applied research.

We create our own models. And so we have hands-on life experience right here. This is part of the co-design that I’m talking about. We’re also the only AI company in the world that works with literally every AI company in the world.

So you’re listening to the whispers across the industry, the AI labs.
Jensen Huang
That’s right. You got to listen and learn from everybody. And have a… And then the last part is to have an architecture that’s flexible, that can adapt and move with the wind. And one of the benefits of CUDA is that it’s, you know, on the one hand, an incredible accelerator. On the other hand, it’s really flexible. And so that balance, incredible balance between specialization, otherwise we can’t accelerate the CPU, versus generalization, so that we can adapt with changing algorithms, that’s really, really important. That’s the reason why CUDA has been so resilient on the one hand, and yet we continue to enhance it.

Jensen Huang
We’re at CUDA 13.2, and so we’re evolving the architecture so fast that we can stay with the modern algorithms. For example… When mixtures of experts came out, that’s the reason why we had NVLink 72 instead of NVLink 8. We could now take an entire 4 trillion, 10 trillion parameter model and put it in one computing domain as if it’s running on one GPU. People probably didn’t notice, I said it, but if you look at the architecture of the Grace Blackwell racks, it was completely focused on doing one thing, processing the LLM. All of a sudden, one year later, you’re looking at a Vera Rubin rack. It has storage accelerators. It has this incredible new CPU called Vera. It has Vera Rubin and NVLink 72 to run the LLMs.

No, it’s easier than that. You just reason about it. First of all, you just reason. No matter, no matter what happens, at some point in order for that large language model to be a digital worker… Let’s just use that metaphor. Let’s say that we want the LLM to be a digital worker. What does that have to do? It has to access ground truth. That’s our file system. It has to be able to do research. It doesn’t know everything. We don’t have… And I don’t wanna wait until this AI becomes, you know, universally smart about everything, past, present, and future before I make it useful. And so therefore, I might as well let it go do research. It’s obvious; if it wants to help me, it’s gotta use my tools.

You know, a lot of people would say, “You know AI is gonna completely destroy software. We don’t need software anymore. We don’t even need tools anymore.” That’s ridiculous. Let’s use the… Let’s use a thought experiment. And you could just sit there, enjoy a glass of whiskey, and think about all these things, and it would become completely obvious. Like, if I were to create the most amazing agent that we can imagine in the next 10 years. Let’s say it’d be a humanoid robot. If that humanoid robot were to be created, is it more likely that the humanoid robot comes into my house and uses the tools that I have to do the work that it needs to do?

Or does this hand turn into a 10-pound hammer in one instance, turn into a scalpel in another instance, and in order to boil water, it beams, you know, microwaves out of its fingers? You know, or is it more likely just to use a microwave, you know? And the first time it goes up to the microwave, it probably doesn’t know how to use it. But that’s okay. It’s connected to the internet. It reads the manual of this microwave, reads it, instantly becomes an expert. And so it uses it. And so I think the… I just described, in fact, almost all of the properties of OpenClaw.

You know, that it’s gonna use tools, that it’s gonna access files, it’s gonna be able to do research. It has an IO subsystem. And when you’re done reasoning through it, reasoning about it in that way, then you say, “Oh, my gosh, the impact to the future of computing is deeply profound.” And the reason for that is, I think we’ve just reinvented the computer. And then now you say, “Okay, when did we reason about that? When did we reason about OpenClaw?” If you take the OpenClaw schematic that I used at GTC, you’ll find it two years ago. Literally, two years ago at GTC, I was talking about agentic systems that exactly reflect OpenClaw today. And, of course, the confluence of many things had to happen.

First of all, we needed Claude and GPT and, you know, all of these models to reach a level of capability. So their innovation and their breakthroughs and their continued advances was really important. And then, of course, somebody had to create an open source project that was sufficiently robust and sufficiently complete and that we can all put to work. And I think OpenClaw did for agentic systems what ChatGPT did for generative systems. And I just think it’s a very big deal.

We could keep things safe if we gave you two out of those three capabilities at any time, but not all three. And out of those two out of three capabilities, we also give you access control based on whatever rights that you’re given by enterprise. And then we connect it to a policy engine that all these enterprises already have. And so we’re going to try to do our best to help OpenClaw become a better claw.

Biggest blockers to AI scaling laws
Lex Fridman
So you eloquently explained how we have a long history of blockers that we thought were going to be blockers, and we overcame them. But now looking into the future, what do you think might be the blockers now that it’s clear that agents will be everywhere? So it’s obviously we’re going to need compute. So what is going to be the blocker for that scaling?

Jensen Huang
Power is a concern, but it’s not the only concern. But that’s the reason why we’re pushing so hard on extreme co-design, so that we can improve the tokens per second per watt orders of magnitude every single year. And so in the last 10 years, Moore’s Law would have progressed computing about 100 times in the last 10 years. We progressed and scaled up computing by a million times in the last 10 years. And so we’re gonna keep on doing that through extreme co-design. So energy efficiency, perf per watt, completely affects the revenues of a company. It affects the revenues of a factory. And we’re just going to push that to the limit so that we can keep on driving token costs down as fast as we can.

Supply chain
Lex Fridman
That’s a really complicated one. You’ve talked about small modular nuclear power plants. There’s all kinds of ideas for energy. How much does it keep you up at night? The bottlenecks in the supply chain of AI, like ASML with EUV lithography machines, TSMC with advanced packaging like CoWoS, and SK Hynix with the high bandwidth memory?

All the time, and we’re working on it all the time. No company in history has ever grown at a scale that we’re growing while accelerating that growth. It’s incredible. And it’s hard for people to even understand this. In the overall world of AI computing, we’re increasing share. And so supply chain, upstream and downstream, are really important to us. I spend a lot of time informing all the CEOs that I work with: what are the dynamics that’s going to cause the growth to continue or even accelerate? It’s part of the reasons why to the entire right-hand side of me were CEOs of practically the entire IT industry upstream and practically the entire infrastructure industry downstream.

And it’s hard for people to even understand this. In the overall world of AI computing, we’re increasing share. And so supply chain, upstream and downstream, are really important to us. I spend a lot of time informing all the CEOs that I work with: what are the dynamics that’s going to cause the growth to continue or even accelerate? It’s part of the reasons why to the entire right-hand side of me were CEOs of practically the entire IT industry upstream and practically the entire infrastructure industry downstream.
Jensen Huang
And they were all… There were several hundred CEOs. And I don’t think there’s ever been keynotes where several hundred CEOs show up. And part of it is, I’m telling them about our business condition now. I’m telling them about the growth drivers in the very near future and what’s happening. And I’m also describing where are we going to go next so that they could use all of this information and all of the dynamics that are here to inform how they want to invest. And so I inform them that way like I inform my own employees.

Memory
Jensen Huang
And then of course, then I make trips out to them and make sure that, “Hey, listen, I want you to know this quarter, this coming year, this next year, these things are going to happen.” And if you look at the CEOs of the DRAM industry—the number one DRAM in the world was DDR memory for CPUs in data centers. About three years ago, I was able to convince several of the CEOs that even though at the time HBM memory was used quite scarcely, and barely by supercomputers, that this was going to be a mainstream memory for data centers in the future. At first it sounded ridiculous, but several of the CEOs believed me and decided to invest in building HBM memories.

Jensen Huang
Another memory was rather odd to put into a data center: the low power memories that we use for cell phones. And we wanted them to adapt them for supercomputers in the data center. And they go, “Cell phone memory for supercomputers?” And I explained to them why. Well, look at these two memories, LPDDR5, HBM4. The volumes are so incredible. All three of them had record years in history, and these are 45-year companies. And so, you know, I… That’s part of my job, is to inform and shape, inspire, you know.

So you’re not just manifesting the future and maybe inspiring NVIDIA, the different engineers of the company, you’re manifesting the supply chain of the future. So you’re having conversations with TSMC, with ASML.

Yeah, the whole thing. I mean, but that’s so… There’s so much incredibly difficult engineering that happens in the entire semiconductor industry, and it just feels scary how intricate the supply chain is, how many components there are, but it works somehow.

Exactly, the deep science. The deep engineering, the incredible manufacturing, and so much of the manufacturing is already robotics, but we have a couple of hundred suppliers that contribute the technology that goes into our 1.3 million component rack. Each rack is 1.3, one and a half million components. There are 200 suppliers across the Vera Rubin rack.

… yeah, see? I can go to sleep because I checked it off. I said, “Okay,” you know, I go, I can go to sleep and I go, “Well, let’s see, let’s reason about this. What’s important for us?” Because let’s reason about this. Because we changed the system architecture from the original DGX-1 that you remembered to NVLink-72 rack scale computing- … what’s gonna… What does that, what does that mean? What does that mean to software? What does that mean to engineering? What does that mean to how we design and test? And what does that mean to the supply chain? Well, one of the things that it meant was we moved supercomputer integration at the data center into supercomputer manufacturing in the supply chain.

Jensen Huang
If you’re doing that, you also have to recognize you’re gonna move one… And if your total footprint of whatever data center you’re gonna build, let’s say you would like to have, you know, 50 gigawatts of supercomputers that are running simultaneously, and it takes one week to manufacture that 50 gigawatts of supercomputers, then each week in the supply chain, the supercomputers are gonna need a gigawatt of power. And so we’re gonna need the supply chain to increase the amount of power it has to build and test the supercomputers in the supply chain before I ship it.

Lex Fridman
Oh.
Oh.
Jensen Huang
Well, NVLink-72 literally builds supercomputers in the supply chain and ships ’em two, three tons at a time per rack. It used to be they used to come in parts and we used to assemble ’em inside the data center. But that’s impossible now because NVLink-72 is so dense. And so that’s an example. And I would have to go and fly into the supply chain, go meet my partners saying, “Hey,” I said, “guess what? So here’s what I’m going to do with… This is the way we used to build our DGXs. We’re gonna build them this way. This is gonna be so much better because we’re going to need ’em for inference.” The market for inference is, you know, coming. The inflection point for inference is coming. It’s gonna be a big market.

And so I first explain to them what’s going on, why it’s gonna happen, and then I ask ’em to make several billion dollars of capital investments each. And because they trust me and I’m very respectful of ’em, and I give ’em every opportunity to question me and I spend time to explain things to people and I reason about it. I draw pictures and I reason about it in first principles. And by the time I’m done with them, they know what to do.

Lex Fridman
So a lot of it is about relationships and building a shared view of the future. But do you worry about certain bottlenecks? I mean, what are the biggest bottlenecks in the supply chain? Are you worried about ASML’s EUV tooling? Are you worried about the packaging, CoWoS packaging of TSMC, about how fast it could scale? Like you said, you’re not only growing incredibly fast, you’re accelerating your growth. So it feels like everybody in the supply chain, and those are certainly bottlenecks, would have to scale up. Are you having conversations with them, like, how can you scale up faster?

Power
Lex Fridman
Interesting. That’s great to hear. So maybe if we can just linger on the power for a little bit. What are your hopes for how to solve the energy problem?

Jensen Huang
One of the areas, Lex, that I would love us to talk about and just get the message out, you know, our power grid is designed for the worst case condition with some margin. Well, 99% of the time we’re nowhere near the worst case condition because the worst case condition is a few days in the winter, a few days in the summer, and extreme weather. Most of the time we’re nowhere near the worst case condition and we’re probably running around, call it 60% of peak.

Jensen Huang
And so 99% of the time, our power grid has excess power, and they’re just sitting idle, but they have to be there sitting idle because just in case, when the time comes, hospitals have to be powered and, you know, infrastructure has to be powered and airports have to run and so on and so forth. And so the question that I have is whether we could go and help them understand and create contractual agreements and design computer architecture systems, data centers, such that when they need the maximum power for infrastructure in society, that the data centers would get less.

Jensen Huang
But that’s in a very rare instance anyways. And during that time, we either have a backup generator for that little part of it, or we just have our computers shift the workload somewhere else, or we have the computers just run slower. You know, we could degrade our performance, reduce our power consumption and provide for a, you know, slightly longer latency response, you know, when somebody asks for, you know, asks for an answer. And so I think that that, that way of using computers, of building data centers, instead of expecting 100% uptime—and these contracts that are really, really quite rigorous, it’s putting a lot of pressure on the grid to be able to… Now, they’re gonna have to increase from their maximum. I just wanna use their excess. It’s just sitting there.

Yeah, that’s not talked about enough. So what’s stopping there? Is it regulation? Is it bureaucracy?
Yeah, that’s not talked about enough. So what’s stopping there? Is it regulation? Is it bureaucracy?
Jensen Huang
I think it’s a three-way problem. It starts with the end customer. The end customer puts requirements on the data centers that they can never not be available, okay? So that the end customer expects perfection. Now, in order to deliver that perfection, you need a combination of backup generators and your grid power supplier to deliver on perfection. And so everybody’s gotta have six nines. Well, I think first of all, right now, we ought to have everybody understand that when the customer asks for these things, you have somebody in your data center operations team disconnected from the CEO. I bet the CEO doesn’t know this. I’m gonna talk to all the CEOs.

The CEOs are probably not paying any attention to the contracts that are being signed, and so everybody wants to sign the best contract, of course. And they go down to cloud service providers, and the two contract negotiators that are… You, I could just see them now. You know, negotiating these multi-year contracts. Both sides want, you know, the best contract. As a result, the CSPs then have to go down to the utilities, and they expect the nine, the six nines. And so I think, I think the first thing is just make sure that, that all of the customers, the CEOs and the customers realize what they’re asking for. Now, the second thing is we have to build data centers that gracefully degrade.

Jensen Huang
And so if the power, if the utility, if the grid tells us, “Listen, we’re gonna have to back you down to about 80%,” we’re gonna say, “That’s no problem at all.” We’re just gonna move our workload around. We’re gonna make sure that data’s never lost, but we can reduce the computing rate and use less energy. The quality of service degrades a little bit. For the critical workloads, I shift that somewhere else right away so I don’t have that problem, and so, you know, whichever data center still has 100% uptime, and so…

So the second thing is the, the data centers. And the third thing is we need the utilities to also recognize that this is an opportunity- … and instead of saying, “Look, it’s gonna take me five years to increase my grid capability,” if you have, if you’re willing to take power of this level of guarantee, I can make them available for you next month and at this price. And so if utilities also offered more segments of power delivery promises, then I think everybody will figure out what to do with it. Yeah, but there’s just way too much waste in the grid right now. We should go after it.

Elon and Colossus
Lex Fridman
You’ve highly lauded Elon and xAI’s accomplishment in Memphis, in building Colossus supercomputer, probably in record time in just four months. It’s now at 200,000 GPUs and growing very quickly. Is there something that you could speak to the understanding about his approach that’s instructive to, broadly to all the data center creators that enabled that kind of accomplishment? His approach to engineering, his approach to the whole management of construction, everything?

First of all, Elon is deep in so many different topics. Yet he’s also a really good systems thinker. And so he’s able to think through multiple disciplines, and he obviously pushes things, questions everything, where they’re, number one, is it necessary? Number two, does it have to be done this way? And then number three, you know, does it have to take this long? And so he has the ability to question everything to the point where everything is down to its minimal amount that’s necessary, you can’t take anything else out. And yet the necessary capabilities of the product remains, you know? And so he is as minimalist as you could possibly imagine, and he does it at a system scale. I think… I also love the fact that he is represented. He is present at the point of action.

You know, he’ll just go there. If there’s a problem, he’ll just go there and then, “Show me the problem.” You know, when you do all of this in combination, you overcome a lot of previous, “This is just the way we do it.” “You know, I’m waiting for them.” You know, I mean, it’s just, everybody has a lot of excuses. And so, and then the last thing is when you act personally with so much urgency, it causes everybody else to act with urgency, you know? And every supplier has a lot of customers going on. Every supplier has a lot of projects going on, and he makes it his business that he’s the top priority of everybody else’s projects. And so he does that by demonstrating it.

And yes, I think when you get the ground truth of actually… I remember… One of the times I was hanging out with him, he literally is going through the entire process of how to plug in cables into a rack. He’s working with an engineer on the ground that’s doing that task, and he’s just trying to understand what does that process look like so it can be less error-prone. And just building up that intuition from every single task involved in putting together a data center-

Jensen’s approach to engineering and leadership
Lex Fridman
Is there parallels in the NVIDIA Extreme Systems co-design approach that you see in the way Elon approaches systems engineering?
Is there parallels in the NVIDIA Extreme Systems co-design approach that you see in the way Elon approaches systems engineering?
Jensen Huang
Well, first of all, co-design is an ultimate systems engineering problem. And so we approach the work that we do from that first principle. The other thing that we do and this is a philosophy that, a thought, a state of mind, I guess, a method that I started 30 years ago, and it’s called the speed of light. The speed of light is not just about the speed. The speed of light is my shorthand for what’s the limit of what physics can do. And so every single thing that we do is compared against the speed of light. Memory speed, math speed, power, cost, time, effort, number of people, manufacturing cycle time.

Jensen Huang
And when you think about latency versus throughput when you think about cost versus throughput, cost versus capacity, all of these things you test against the speed of light to achieve all of these different constraints separately. And then when you consider it together, you know you have to make compromises because a system that achieves extremely low latency versus a cheap, a system that achieves very high throughput are architected fundamentally differently. But you want to know what’s the speed of light of a system that achieves high throughput, what’s the speed of light of a system that achieves low latency? And then when you think about the total system, you can make trade-offs. And so I force everybody to think about what’s the first principles, the limits-

Jensen Huang
… the physical limits for everything before we do anything. And we test everything against that. And so that’s a good frame of mind. I don’t love the other methods, which is continuous improvement. The problem with continuous improvement, it… First of all, you should engineer something from first principles at the speed, you know, with speed of light thinking. Limit it only by physical limits, and physics limits. And after that, of course you would improve it over time. But I don’t like going into a problem and somebody says, “Hey, you know, it takes 74 days to do this today-” “… Right now. And we can do it for you in 72 days.” You know, I’d rather strip it all back to zero-

The problem with continuous improvement, it… First of all, you should engineer something from first principles at the speed, you know, with speed of light thinking. Limit it only by physical limits, and physics limits. And after that, of course you would improve it over time. But I don’t like going into a problem and somebody says, “Hey, you know, it takes 74 days to do this today-” “… Right now. And we can do it for you in 72 days.” You know, I’d rather strip it all back to zero-
Jensen Huang
… and say, “First of all, explain to me why 74 days in the first place. And l- let’s note, let’s think about what’s possible today. And if I were to- to build it completely from scratch, you know, how long would it take?” Oftentimes, you’d be surprised. It might come to six days. Now, the rest of the six days, the 74, could be very well-reasoned and compromises, and, you know, cost reductions, and all kinds of different things. But at least you know what they are. And then now that you know that six days is possible, then the conversation from 74 to six, surprisingly much more effective.

In such incredibly complex systems that you’re working with, is simplicity sometimes a good heuristic to reach for? I mean, if I can just… I mean, the pod, the Vera Rubin pod that you announced is just incredible. We’re talking about seven chips, seven chip types, five purpose-built rack types, 40 racks, 1.2 quadrillion transistors, nearly 20,000 NVIDIA dies, over 1,100 Rubin GPUs, 60 exaflops, 10 petabytes per second of scale bandwidth. That’s all just one…

You know, the phrase that I use most often is, we need things to be as complex as necessary, but as simple as possible. And so the question is, is all that complexity there necessary? And we ought to test for that. And we got to challenge that. And then after that, everything else above it, you know, is gratuitous.

And have to work together. And report directly to you. This is wonderful. You recently traveled to China. So it’s interesting to ask you, China’s been incredibly successful in building up its technology sector. What do you understand about how China’s able to, over the past 10 years, build so many incredible world-class companies, world-class engineering teams, and just this technology ecosystem- … that produces so many incredible products?

Jensen Huang
A whole bunch of reasons for… Well, first of all, let’s start, let’s start with some facts. 50% of the world’s AI researchers are Chinese, plus or minus, and they’re mostly in China still. We have many of them here, but there’s amazing researchers still in China. They—their tech industry showed up at precisely the right time. At the time of the mobile cloud era, their way of contributing was software, and so this is a country’s incredible science and math really well-educated kids. Their tech industry was created during the era of software. They’re very comfortable with modern software. China is not one giant economic country. It’s got many provinces and cities with mayors all competing with each other.

Jensen Huang
That’s the reason why there’s so many EV companies. That’s the reason why there’s so many AI companies. That’s the reason why there’s so many—every company you could imagine, they all create some of them. And, and as a result, they have insane competition internally. And, you know, what remains is an incredible company. They also have a social culture where, where it’s family first, friends second, and company third. And so the amount of conversation that goes back and forth between… They’re essentially open source all the time.

Jensen Huang
So the fact that they contribute more to open source is so sensible because they’re probably, “What are we protecting?” You know, my engineers, their brothers are in that company, their friends are in that company, and they’re all schoolmates. You know, the schoolmate concept. There’s a, you know, one schoolmate, you’re brother for life. And and so they, they, they share knowledge very, very quickly. And so there’s no sense keeping technology hidden. You might as well put it on open source. And so the open source community then amplifies, accelerates the, the innovation process. So you get this rapid, incredible great talent, rapid innovation because of open source and just, you know, the nature of friends, and, and insane competition.

Among the company, what emerges is incredible stuff. And so this is the fastest innovating country in the world today, and this is something that has everything that, everything that I’ve just said is fundamental to just how the kids were grown, the fact that they have excellent education, the fact that they, parents want them to do well in school, the fact that they, their culture is that way. These are, you know, these are just the thing about their country, and they showed up at precisely the time when technology is going through that exponential.

First, if we’re gonna be a great AI computing company, we have to understand how AI models are evolving.
Jensen Huang
One of the things that I love about Nemotron 3 is it’s not just a pure transformer model, it’s transformer and SSMs. And we were early in developing the, the conditional GANs, which, that progressive GANs, which led step-by-step to diffusion. And so the fact that we’re doing basic research in model architecture and in different domains gives us visibility into, you know, what kind of computing systems would do a good job for future models. And so it is part of our extreme co-design strategy. Second, I think we rightfully recognize that on the one hand, we want world-class models as products, and they should be proprietary. On the other hand, we also want AI to diffuse into every industry and every country, every researcher, every student.

Jensen Huang
And if everything is proprietary, it’s hard to do research and it’s hard to innovate on top of, around, with. And so… Open source is fundamentally necessary for many industries to join the AI revolution. NVIDIA has the scale and we have the motives—not only skills, scale, and motivation—to build and continue to build these AI models for as long as we shall live. And so therefore, we ought to do that. We can open up, we can activate every industry, every researcher, you know, every country to be able to join the AI revolution. There’s the third reason, which is from that, to recognizing that AI is not just language. These AIs will likely use tools and models and sub-agents that were trained on other modalities of information.

Jensen Huang
Maybe it’s biology or chemistry or you know, laws of physics, or you know, fluids and thermodynamics, and not all of it is in language structure. And so somebody has to go make sure that weather prediction, biology, AI, AI for biology, physical AI, all of that stuff stays, can be pushed to the limits and pushed to the frontier. We don’t build cars, but we wanna make sure every car company has access to great models. We don’t discover drugs, but I wanna make sure that Lilly has the world’s best biology AI systems, so that they can go use it for discovering drugs. And so these three fundamental reasons, both in recognizing that AI is not just language, that AI is really broad, that we wanna engage everybody into the world of AI, and then also co-design of AI.

TSMC and Taiwan

It’s really incredible. You’re originally from Taiwan and have a close relationship with TSMC. So I have to ask TSMC I think also is a legendary company in terms of the engineering teams, in terms of the incredible engineering work that they do. What do you understand about TSMC culture and their approach that explains how they’re able to achieve this singular unmatched success in everything they’re doing with semiconductors?

Jensen Huang
You know, first of all, the deepest misunderstanding about TSMC is that their technology is all they have. That somehow they have a really great transistor, and if somebody shows up another transistor, game over. It’s the technology and, of course, you know, I don’t mean just the transistor, the metallization systems, the packaging, the 3D packaging, the silicon photonics, the, you know, all of the technology that they have. That technology is really what makes the company special. Their technology makes the company special.

But their ability to orchestrate the demands, the dynamic demands of hundreds of companies in the world as they’re moving up, shifting out, you know, increasing, decreasing, pushing out, pulling in, changing from customer to customer, wafer starting, wafer stopping, emergency wafer starts, you know, all of this dynamics of the world’s complexity as the world is shape-shifting all the time, and somehow they’re running a factory with high throughput, high yields, really great costs, excellent customer service. They take their promises seriously.

They, when your wafer—because they know that they’re helping you run your company—when the wafers were promised to show up, the wafers show up, you know, so that you could run your company appropriately. And so their system, their manufacturing system is completely miraculous, I would say. Then the second thing is their culture. This culture is simultaneously technology focused on one hand, advancing technology; simultaneously customer service oriented on the other hand. A lot of companies are very customer service oriented, but they’re not very technology excellent. They’re not at the bleeding edge of technology.

There are a lot of companies who are tech, at the bleeding edge of technology, but they’re not the best customer service oriented company. And so it just depends on somehow they’ve, they’ve balanced these two and they’re world-class at both. And then probably the third thing is the technology that I most value in them that they created this, you know, this, this intangible called trust. I trust them to put my company on top of them. That’s a very big deal.

And Morris is one of the highest regarded executives and business and personal friend that I’ve had in my life. And, for him to ask, I was humbled and really honored. But the work that I’m doing here is really important, and I’ve seen, you know, in my mind’s eye, what NVIDIA was going to be and what the impact that we could have. And it was really important work. And it’s my responsibility, you know, my sole responsibility to make this happen. And so I declined it, not because it wasn’t an incredible offer. It’s an unbelievable offer, but I simply couldn’t take it.

Our single most important property as a company is the install base of our computing platform. Our single most important thing today is the install base of CUDA. Now, the reason why 20 years ago, of course, there was no install base. But what makes… And if somebody came up with a GUDA or TUDA, it wouldn’t make any difference at all. And the reason for that is because it’s never been just about the technology. The technology, of course, was incredible, visionary. But it’s the fact that the company was dedicated to it, stuck with it, expanded its reach. It wasn’t three people that made CUDA successful. It was 43,000 people that made CUDA successful.

Jensen Huang
And the several million developers that believed in us that trusted that we were going to continue to make CUDA 1, 2, 3, 13, that they decided to port and dedicate their software on top of it, their mountain of software on top of it. And so the install base is the number one most important advantage. That install base, when you amplify it with the velocity of our execution at the scale that we’re talking about, no company in history had ever built systems of this complexity, period. And then to build it once a year is impossible. And that velocity combined with the install base, in the developer’s mind, you just go now, take the developer’s mind. From the developer’s perspective, if I support CUDA, tomorrow it’ll be 10 times better. I just have to wait six months on average.

Not only that, if I develop it on CUDA, I reach a few hundred million people, computers. I’m in every cloud, I’m in every computer company, I’m in every single industry, I’m in every single country. So if I create an open source package and I put it on CUDA first, I get these both attributes simultaneously. And not only that, I trust 100% that NVIDIA is going to keep CUDA around and maintain it and improve it and keep optimizing the libraries for as long as they shall live. You could take that to the bank, and that last part, trust. You put all that stuff together, if I were a developer today, I would target CUDA first. I would target CUDA most. And that’s the reason that I think in the final analysis is our first, that’s even our first-

And that’s the reason that I think in the final analysis is our first, that’s even our first-

… core advantage. Our second one is our ecosystem. The fact that we vertically integrated this incredibly complex system, but we integrate it horizontally into every single company’s computers. We’re into Google Cloud, we’re into Amazon, we’re in Azure. You know, we’re ramping up AWS like crazy right now. We’re in new companies like CoreWeave and Nscale. We’re in supercomputers at Lilly. We’re in enterprise computers. We’re at the edge in radio base stations. You know, I mean, it’s just crazy. One architecture is in all these different systems. We’re in cars, we’re in robots, we’re in satellites, we’re out in space. And so the fact that you have this one architecture and the ecosystem is so broad, it basically covers every single industry in the world.

Well, how does the CUDA install base evolve into the future with AI factories as a moat? What do you… Do you think it’s possible that NVIDIA of the future is all about the AI factory?

Jensen Huang
Well, the unit of computing used to be GPU to us. Then it became a computer, then it became a cluster. Now it’s an entire AI factory. When I see a computer, when I see what NVIDIA builds, in the old days, I would, you know, I visualize the chip. And then when I announced the new product, new generation, like, “Ladies and gentlemen, we’re announcing Ampere today,” I’d pick up the chip. That was my mental model- … of what I was building. Today, I wouldn’t… Picking up the chip is kind of still adorable.

Jensen Huang
But it’s adorable. It’s not my mental model of what I’m doing. My mental model is this giant gigawatt thing that has power generations connected to the grid. It’s got cooling systems and networking of incredible monstrosity, you know. 10,000 people are in there trying to install it, hundreds of networking engineers in there, thousands of engineers behind it trying to power it up. You know, powering up one of those factories, as you know, it’s not somebody going, “It’s on now.” It takes thousands of people to bring it up.

So mentally, you’re actually… When you’re thinking about a single unit of compute, you’re like literally, when you go to bed at night, you’re thinking now about a collection of racks, so pods, not individual chips.

Yeah, we’re already there. NVIDIA GPUs are the first GPUs in space. And I didn’t realize it, it was so interesting to… I would have declared it maybe. We’re in space. You know, little, little astronaut suit on one of our GPUs. But we’ve been in space. It’s the right place to do a lot of imaging.

Jensen Huang
You know, because those satellites have really high resolution imaging systems, and they’re sweeping the Earth, you know, continuously now. And you want, you know, centimeter scale imaging that is done continuously for the world, so that, you know, you’ll basically have real time telemetry of everything. You don’t wanna beam that back down to Earth. It’s just, you know, petabytes and petabytes of data. You gotta just do AI right there at the edge, throw away everything you don’t need, you’ve seen before, didn’t change, and then just keep the stuff that you need. And so AI had to be done at the edge. Obviously we have 24/7 solar, if we put it at the polars. And but, you know, there’s no conduction, no convection.

You know, I’m just so much more practical. I look for where my next, next bucket of opportunities are first. Meanwhile, I’m cultivating space. And so I send, I send engineers to go work on the problem. We’re starting to… We’re learning a lot about it. How do we deal with radiation? How do we deal with degrading performance? How do we deal with a continuous testing and attestation of defects? And you know, how do we deal with redundancy? And how do we degrade gracefully and things like that? And so we could do a… What about software? How do you think about software and redundancy and performance out in space?

Make it so that the computer never breaks, it just gets slower, you know. And I… So we could start doing a lot of engineering exploration upfront. But in the meantime, my favorite answer is eliminate waste. You know, we’ve got all that idle power, I want to evacuate it as fast as possible.

Will NVIDIA be worth $10 trillion?
Jensen Huang
I think that NVIDIA’s growth is extremely likely, and in my mind, inevitable. And let me explain why. We’re the largest computer company in history. That alone should beg the question, why? And the reason of course… Two reasons. First, two foundational technical reasons. The first reason is that computing went from being a retrieval-based, file retrieval system. Almost everything is a file… We pre-write something, we pre-record something. You know, we draw something, we put it on the web, we put it in a file. And we use a recommender system, some smart filter, to figure out what to retrieve for you. And so we were a pre-recording, human pre-recording, and file retrieving system. That’s what a computer is, largely.

Jensen Huang
To now, AI computers are contextually aware, which means that it has to process and generate tokens in real time. So we went from a retrieval-based computing system to a generative-based computing system. We’re gonna need a lot more processing in this new world than in the old world. We need a lot of storage in the old world. We need a lot of computation in this new world. And so that’s the first part of it. We fundamentally changed computing and the way how computing is done. The only thing that would cause it to go back……

Jensen Huang
is if this way of computation, this way of computing generating information that’s contextually relevant, situationally aware, that is grounded on new insight before it generates information, this computation-intensive way of doing computing would only go back if it’s not effective. So if… For the last 10, 15 years while working on deep learning, if at any single moment I would have come to the conclusion that, “You know what? This is not gonna work out. I think this is a dead end.” Or, “It’s not gonna scale, it’s not gonna solve this modality, not gonna be used in this application.” Then, of course, I would feel very differently about it, but I think the last five years has given me more confidence than the previous ten years.

The second idea is computers, because it was a storage system, it was largely a warehouse. We’re now building factories. Warehouses don’t make much money. Factories directly correlates with the company’s revenues. And so, the computer did two things. Not only did it change the way it did it, its purpose in the world changed. It’s no longer a computer, it’s a factory. It’s a factory, it’s used for generation of revenues. We’re now seeing not only is this factory generating products, commodities that people want to consume, we’re seeing that the commodities are so interesting, so valuable to so many different audiences that the tokens are starting to segment, like iPhones. You have free tokens, you have premium tokens, and you have several tokens in the middle.

Jensen Huang
And so intelligence, as it turns out, you know, it’s a scalable product. There’s extremely high intelligence products, tokens that you could… that are used for specialized things, people be willing to pay. You know, the idea that somebody’s willing to pay $1000 per million tokens is just around the corner. It’s not if, it’s only when. And so, so now we’re seeing that the commodity that this factory makes is actually valuable, and is revenue generating and profit generating. Now the question is how many of these factories does the world need? How many tokens does the world need? And how much is society willing to pay for these tokens? And what would happen to the world’s economy if the productivity were to improve so substantially? What would happen…

Are we, are we gonna discover new drugs, new products, new services? And so when you take these things in combination, I am absolutely certain that the world’s GDP is going to accelerate in growth. I’m absolutely certain the percentage of that GDP that will be used for computation will be 100 times more than the past—mm-hmm—because it’s no longer a storage unit. It’s a product generation unit. And so when you look at it in that context and then you back into what is NVIDIA’s, what does NVIDIA sh—what does NVIDIA do and how much of that new economics, new industry would we have to benefit t—to address, I think we’re gonna be a lot, lot bigger.

Jensen Huang
And then the rest of it, to me, is: is it possible for NVIDIA to be a, you know, $3 trillion revenue company in the near future? The answer is, of course, yes. And the reason for that is because it’s not limited by any physical limits. There’s nothing that I see that says, you know, gosh $3 trillion is not possible. And as it turns out, NVIDIA’s supply chain is—the burden is shared by 200 companies. And the fact that we scale out on the backs of, with the partnership of this ecosystem, the question is: do we have the energy to do so? And surely we will have the energy to do so. And so all of these things combined, that number is just a number, you know?

Jensen Huang
And I still remember, NVIDIA was a… the first time we crossed a billion dollars, I was reminded of a CEO who told me, “You know, Jensen, it’s theoretically impossible for a fabless semiconductor company to exceed a billion dollars.” And I won’t bore you with why, but of course it’s illogical and there’s a lot of evidence we’re not. And then somebody told me, “You know, Jensen, you’ll never be more than $25 billion because of some other company.” Somebody told me that, “You’ll never be, you know, because…” And so those aren’t principled, first principled reason thinking. And the simple way to think about that is what is it that we make and how large is the opportunity that we can create?

Jensen Huang
Now, NVIDIA is not in the market share business. Almost everything that I just talked about don’t exist. That’s the part that’s hard. You know, if NVIDIA was a $10 billion company trying to take NVIDIA’s share, then it’s easy to see for shareholders that, oh, yeah, if they could just take 10% share, they could be this much larger. But it’s hard for people to imagine how large we could be because there’s nobody I could take share from. You know? And so I think that that’s one of the challenges for the world is the imagination of the future. But I got plenty of time, and I’ll keep reasoning about it, and I’ll keep talking about it, and every single GTC will become more and more real.

Yeah, this view of you know, token factories essentially, this token per second per watt, and every token having value. Like it’s an actual thing that brings value, and it brings different kinds of value, different amounts of value to different people with value. That’s the actual product—it really could be loosely thought of as the token. And so you have a bunch of token factories. And then it’s very easy, first principles, to imagine a future, given all the potential things that AI can solve, that you’re going to need an exponential number more of token factories.

And it’s more likely that your AI is bothering you all the time. And the reason for that is because it’s getting stuff done so fast. It’s reporting back to you, “I got that done.” “You know, what do you want me to do next?” You know, it… That’s the part that I think most people don’t realize is the person who’s gonna be chatting with them, texting them most, is their, is their claws or lobster.

Leadership under pressure
Lex Fridman
What an incredible future. I read that you attribute a lot of your success to your ability to work harder than anyone and withstand more suffering than anyone. So we can list many of the things that entails. I mean, dealing with failure, the cost and engineering problems we’ve talked about. The human problems, uncertainty, responsibility, exhaustion, embarrassment, the near-death company moments that you’ve mentioned but also the pressure. Now, as the CEO of this company that economies and nations strategize around, plan their financial allocations around, plan their AI infrastructure around, how do you deal with this much pressure? What gives you strength, given how many nations and peoples depend on you?

I’m conscious about the fact that NVIDIA’s success is very important to the United States. We generate enormous amounts of tax revenues. We established technology leadership for our nation. Technology leadership is important for national security. National security not just in one aspect of national security, all aspects of national security. When our country’s more prosperous, we could do a better job with domestic policies and helping social benefits. Because we’re generating so much re-industrialization in the United States, we’re creating mountains of jobs. We’re helping shift how we build things back to the United States in so many different plants, chips, computers, and of course, these AI factories. I’m completely aware that, that…

And I am completely aware of that circumstance. I’m aware of the circumstance that NVIDIA is central to a very large network of ecosystem partners behind us and downstream from us. And so the way I deal with that is exactly what I just did. I reason about what is… what is it that we’re doing? What is it causing? What’s the impact that has on other people benefit, you know, positively or even through great burden, for example, to supply chain? And the question is therefore, what are you gonna do about it? In almost everything that I feel, I break it down, I reason about, “Okay, what’s the circumstance? What has changed? What’s hard? And what am I gonna do about it?” And I’m…

I break it down, decompose the problem, and the decomposition of these circumstances turns it into manageable things that I can do. And the only thing that after that I could do is, “Did you do it? Did you either do it or did you get somebody else to do it? And if you didn’t do it, you reasoned that you need to do it, and you didn’t do it, and you didn’t get anybody else to do it, then stop crying about it.”… you know? And so, and so-

so I’m fairly tough on myself. And, but I also break things down so that I don’t panic. I can go to sleep because I’ve made the list of things that needed to be done, and I’ve made sure that everything that could put our company in harm’s way, could put my partners in harm’s way, put our industry in harm’s way, I’ve told somebody. Everything that I feel could put anybody in harm’s way, I’ve told someone. And I’ve told that someone who could do something about it. And so I’ve gotten it off my chest or I’m doing something about it. And so after that, Lex, what else can you do?

And part of it, Lex, part of it is forgetting. One of the most important attributes of AI learning, as you know, is, right? Systematic forgetting. You need to know when to forget some things. You can’t memorize everything. You can’t keep everything and, you know, you don’t want to carry everything. One of the things that I do very quickly is decompose the problem, I reason about the problem, and I share the load with it. When I say I tell everybody, I’m essentially sharing that burden.

As quickly as possible. Whatever worries me, tell somebody else. Don’t just keep it. You know, don’t freak them out. Decompose the problem into smaller parts and get people to, and inspire them to be able to go do something about it. But part of it is just forgetting. You know, like, a lot of it is you gotta be tough on yourself. You know, just come on, stop crying about it. Let’s get going. You know? And then you get out of bed. And then the other part is you’re attracted to the next shiny light, the next future, the next opportunity, the next, “Okay, that’s behind us. What’s next?” It’s a lot, I think, you know, you watch this with great athletes. They just worry about the next point. The last point is behind them. The embarrassment, the, you know- … the setback.

You know, and because I do so much of my job publicly, you know? Lex, you do a fair amount of your job publicly too. And so I do a lot of my job publicly. And so you know, I say a lot of things that seem sensible at the time or funny at the time, mostly it’s just because it’s funny to me at the time.

Exactly. That is, by the way, what I was trying to explain, is that there’s an incredible superpower of having the mind of a child. You know? And I say to myself oftentimes when I look at something, and almost everything my first thought is, “How hard can it be?” You know? And so you get yourself into that mode, how hard could it be? And nobody’s ever done it. It looks gigantic. It’s gonna cost hundreds of billions of dollars. It’s gonna take, you know, all this… And you just go, “Yeah, but how hard could it be?” You know? How hard could it be?

And so, you gotta get yourself into that state of mind. You don’t wanna actually over-simulate everything and all the setbacks and all the trials and tribulations and all the disappointments. You don’t wanna simulate all that in advance. You don’t wanna know that. You wanna go into a new experience thinking it’s gonna be perfect, it’s gonna be great, it’s gonna be incredibly fun. And then while you’re there, you know, you need to have endurance, you need to have grit, so that when the setbacks actually happen, and those setbacks are gonna surprise you, the disappointments are gonna surprise you, the embarrassments are gonna surprise you, the humiliations are gonna surprise you.

You just can’t let… Now you just gotta turn on the other bit, which is just forget about it. Move on, keep moving. And to the extent that my assumptions about the future and why the future is gonna manifest, so long as those assumptions and that input doesn’t change or didn’t change materially, then I should expect that the output won’t change. And so my simulated output of the future is still gonna happen. And if it’s still gonna happen, I’m still gonna go after it.

I believe it’s gonna, you know, and so there’s a combination of two or three human characteristics: the ability to go into an experience fresh-minded, the ability to forget the setbacks, the ability to believe in yourself, you know, to believe what you believe and stay true to that belief. But you’re constantly reevaluating.

This combination of three, four, five things I think is really important for resilience. And, you know, I’m fortunate that whatever life experiences led to this, I’ve got kind of those four, five things. You know, I’m always curious, always learning. I’m always learning from everybody, you know? I’m always asking my… And because I’m humble about everything, I’m always thinking, “Gosh, they did that so nicely. They did that so wonderfully.” You know, I wonder what they’re thinking through. How do they… So I’m simulating everybody. In a lot of ways, you know, I’m emulating almost everybody I watch, right? You’re empathetic towards everything that they do that you’re observing and respect. And so you’re constantly learning and, you know.

You’re now one of the wealthiest people on Earth. One of the most successful humans on Earth. Is it harder to be humble and to be able to… Do you feel the effect of money and power and fame in making it harder for you to sort of be wrong in your own head? Enough to hear out an opinion of somebody else when they disagree with you and learn from them? Those kinds of things.

And when I’m wrong—when I’m wrong or it didn’t turn out that way or, you know, I mean, most of the things that I say outside I’m fairly certain about. And the reason for that is because it’s gonna impact somebody else and I want to be quite concerned about that and quite circumspect about that. For stuff that I’m reasoning about inside a meeting, you know, a lot of things could turn out differently. And so, but it doesn’t ever stop me from reasoning. The way that I manage and lead, I’m constantly reasoning in front of people. And even when I’m talking to you, you can kind of see me reasoning through things. And I want to make sure that you understand what I’m saying not because I told you-

And so I’m doing that all day long in meetings. With all of my employees, I’m constantly reasoning through, “Let me tell you how I see it.” And then I reason through it. It gives everybody the opportunity to intercept and say, “I disagree with that part.” The nice thing about reasoning through things and letting people interact with it is that they don’t have to disagree with your outcome. They can disagree with your reasoning steps. And they could pull me in different directions, and then we can reason forward. And so we’re kind of, you know, a collective path searching method. And it’s really fantastic.

Yes, that’s… The tolerance… I mean, that’s a real thing. Is many years of embarrassing yourself. Even those meetings knowing that there’s people around you where you declared one idea and it was shown that that idea was wrong- … and be able to admit that and to grow from that.

And then later they’re using CUDA, and then later they’re using NVIDIA and, you know, Blender and Dassault and Autodesk.

Yeah. I think their perspective makes sense and I could see where they’re coming from, because I don’t love AI slop myself. You know, all of the AI-generated content increasingly looks similar and they’re all beautiful, and so I’m empathetic towards what they’re thinking. That’s just not what DLSS 5 is trying to do. I showed several examples of it. But DLSS 5 is 3D-conditioned, 3D-guided. It’s ground truth structure data guided. And so the artist determined the geometry. We are completely truthful to the geometry maintained in every single frame. It’s conditioned by the textures, the artistry of the artist. And so every single frame, it enhances but it doesn’t change anything.

Now, the question is about enhancing. DLSS 5 also lets, because the system is open, you could train your own models to determine, and you could even in the future prompt it. You know, I want it to be a toon shader. I want it to look like this kind of, so you can give it even an example. And it would generate in the style of that, all consistent with the artistry, the style, the intent of the artist. And so all of that is done for the artist, so that they can create something that is more beautiful but still in the style that they want. I think that they got the impression that the games are gonna come out the way the games are, shipped the way they do, and then we’re gonna post-process it. That’s not what DLSS is intended to do.

I think the gamers might also appreciate that in the last couple of years, we introduced skin shaders to the game developers. And many of those games have skin shaders that include subsurface scattering that make skin look more skin-like. And so the industries, you know, game developers are looking for more and more tools to express their art. And so this is just yet one more tool, and they get to decide what to use.

I would say Doom, from an art, the intersection of the cultural implication as well as the industry, turning a PC into a gaming device. That was a very important moment. Now, of course, flight simulation companies were before it. And but they just didn’t have the popularity that Doom did to have made the industry turn the PC from an office automation tool into a personal computer for families and gamers and things like that. And so Doom was really impactful there. From an actual game technology perspective, I would say Virtua Fighter. And so we’re great friends with both of them, you know?

No. It has to be worth more than a billion, more than a billion dollars. So, you know, you know how hard it is to do all those components. So, how far are we away from that? So, we’re talking about Open-Claude that does all the incredibly complex stuff that are required to, first of all, innovate, to find customers, to sell to them, to manage, to build a team of some agents, some humans, all that kind of stuff. Is this five, 10, 15, 20 years away?

Possible, and the reason for that is this. You said a billion, and you didn’t say forever. And so for example… It is not out of the question that a Claude was able to create a web service, some interesting little app that all of a sudden, you know, a few billion people used for 50 cents, and then it went out of business again shortly after. Now, we saw a whole bunch of those type of companies during the internet era, and most of those websites were not anything more sophisticated than what Open-Claude could generate today.

Well, by the way, it’s happening right now, right? You know that when you go to China you’re gonna see, you’re gonna see a whole bunch of people teaching their, getting their Claudes to try to go out and look for jobs and, you know, do work, make money. And I’m not, I’m not actually… I wouldn’t be surprised if some social thing happened or somebody created a digital influencer, super, super cute, or some social application that, you know, feeds your little Tamagotchi or something like that, and it become out of the blue an instant success. A lot of people use it for a couple of months and it kind of dies away. Now, the odds of 100,000 of those agents building NVIDIA is zero percent.

And then, and then the one part that I will, I won’t do and I wanna make sure we all do, is to recognize that people are really worried about their jobs. And I just want to remind them that the purpose of your job and the tasks and tools that you use to do your job are related, not the same. I’ve been doing my job for 33 years. I’m the longest running tech CEO in the world, 34 years. And the tools that I’ve used to do my job has changed continuously in the last 34 years, and sometimes quite dramatically, you know, over the course of a couple, two, three years. And the one story that I really wanna make sure that everybody hears is the story that the first job that computer scientists said, AI researchers said was gonna go away was radiology.

Okay? And so it’s been a long time since computer vision has been superhuman. And so the prediction was radiologists would go away because studying radiology scans was a thing of the past. AI will do that. Well, they were absolutely right. Computer vision is completely superhuman. Every radiology platform and package today is driven by AI, and yet the number of radiologists grew. And so the question is why? And we now have a shortage of radiologists in the world. And so, one, the alarmist warning went too far and it scared people from doing this profession that is so important to society. And so it did harm. Now, why was it wrong? The reason why is because the purpose of a radiologist, the purpose is to diagnose disease and help patients and doctors diagnose disease.

And because we’re able to study scans so much faster now, you could study more scans, you could diagnose better, you could in-patient faster, you can see people more. The hospitals are making more money. You have more patients in the hospital. You need more radiologists. I mean, the amazing thing is, it’s so obvious this was gonna happen. The number of software engineers at NVIDIA is gonna grow, not decline. And the reason for that is because the purpose of a software engineer and the task of a software engineer coding are related, not the same. I wanted my software engineers to solve problems. I didn’t care how many lines of code they wrote, you know? But their job, their purpose of their job didn’t change.

Do you think it’s possible that… Let’s even take coding. Do you think the number of programmers in the world might increase, not decrease?
Jensen Huang
Yes. And the reason for that is this. What is the definition of coding? I believe it is… The definition of coding, as of today, is simply specifying, specification, and maybe if you want to be rather directive, you could even give it an architecture of the software that you wanted to write. So the question is, how many people could do that? Describe a specification for a computer to go… telling the computer what to go build. How many people? I think we just went from 30 million to probably 1 billion. And so every carpenter in the future will be a coder, except a carpenter with AI is also an architect. They’ve just increased the value that they could deliver to the customer. Their artistry just elevated tremendously.

So, all of these professions have just been elevated… and if I were a carpenter, I see AI, I would just completely go berserk.

And the reason for that, Lex, and you know, as you’re saying for the audience, I think the goal of, the goal of specification, the artistry of specification, the goal and the artistry of it is going to depend on what problem you’re trying to solve. When I’m thinking, when I’m thinking about giving the company strategies and formulating corporate directions and things that we should do, I describe it at a level that is sufficiently specific that people generally understand the direction and it’s actionable. It’s specific enough that they can take action on it, but I under-specify it on purpose, so that enables 43,000 amazing people to make it even better than I imagined.

And so when I’m working with engineers and when I’m working with people, I think about who, what problem am I trying to solve? Who am I working with? And the level of specification, the level of architecture definition relates to that. And so everybody’s going to have to learn how, where in the spectrum of coding they want to be. Writing a specification is coding. And so you might decide to be quite prescriptive because there’s a very specific outcome you’re looking for. You might decide that, you know, this is an area you want to be much more exploratory, and so you might under-specify and enable you to go back and forth with the AI to even push your own boundaries of creativity. And so this artistry of where you are in the spectrum, this is the future of coding.

But just to linger on it outside of coding, I think a lot of people, rightfully so, are worried about their jobs, have a lot of anxiety about their jobs, especially in the white-collar sector. I don’t think any of us know what to do with tumultuous times that always come when automations and new technology arrives. And I just… First of all, I think we all need to have compassion and the responsibility to feel sort of the burden of what the actual suffering feels like for individual people and families that lose their job. I think whenever you have transformative technology like that’s coming with artificial intelligence, there’s going to be a lot of pain, and I don’t know what to do about that pain.

Hopefully, it creates much more opportunities for those same people for the same kind of job as the tooling evolves and makes them more productive and makes them more fun, hopefully, as it does in the programming. I have been having so much fun programming, I have to say. Like, I’ve never had this much fun. So hopefully it makes their job, automates the boring parts and makes the creative parts the ones that the human beings are responsible for. But still there’s going to be a lot of pain and suffering.

But for the stuff that you can do something about, let’s reason, reason about it and let’s go do it.”

And so I would advise that every college student, every teacher should encourage their student to go use AI. Every college student should graduate and be an expert in AI. And everybody, if you’re a carpenter, if you’re an electrician, go use AI. Go see what it can do to transform your current job, elevate yourself.

And, you know, that loop, that loop, is the… Fundamentally what intelligence is. Intelligence is not one word that is exactly equal to humanity. And that’s, I think it’s really important to separate the two. We have two words for that. I’m not… I don’t over-fantasize about, and I don’t over-romanticize about intelligence. Intelligence is… And people have heard me say it before, I actually think intelligence is a commodity. I’m surrounded by intelligent people. And I’m surrounded by intelligent people more intelligent than I am in each one of the spaces that they’re in.

And yet, I have a role in that circle. It’s actually kind of interesting. They’re more educated than I am. They went to better schools than I did. They’re deeper in any of the fields that they’re in. All of them. I have 60 of them. They’re all superhuman to me. And somehow, I’m sitting in the middle orchestrating all 60 of them. And so you gotta ask yourself… What is it about a dishwasher that allows that dishwasher to sit in the middle of superhumans? Does that make sense?

Jensen Huang
And so, but that’s my point. My point is intelligence is a functional thing. Humanity is not specified functionally. It’s a much, much bigger word. And our life experience, our tolerance for pain, our determination, those are different words than intelligence. And so the thing that I wanna help the audience understand, if I could give them one thing, is intelligence is a word that we’ve elevated to a very high form over time.

All those things.

All of those things. Compassion, generosity, all of the things that you say just now, I believe those are superhuman powers. And that now intelligence is gonna be commoditized. Because we’ve spoken about it, the most important thing is your education. Now, even when they said the most important thing is your education, when you went to school, there’s more than just knowledge that you gained.

And so, but unfortunately, our society had put everything into one single word, and life is more than one word. And I’m just telling you, my life would suggest that being lower on the intelligence curve than everybody around me doesn’t change the fact I’m the most successful. And so, and I think that kind of is—I’m trying to hopefully to inspire everybody else—that don’t let this democratization of intelligence, this commoditization of intelligence, cause you anxiety. You should be inspired by that.

Yeah. I think AI will help us celebrate humans more. And certainly humanity and human first, and I think what makes this world incredible is humans forever will be so, and just AI is this incredible tool that makes us-

Mortality
Lex Fridman
So much of the success of NVIDIA and the lives of millions of people that I mentioned depend on you. But you’re just one human, like we mentioned, a mortal like all of us. Do you think about your mortality? Are you afraid of death?

Jensen Huang
I really don’t wanna die. I have a great life. I have a great family. I have really important work. This is not a once in a lifetime experience suggests that it has been experienced by many people, just not one person. This is a once in a humanity experience, what I’m going through. NVIDIA is one of the most consequential technology companies in history. We’re doing very important work. I take it very seriously. And so some of the things that of course are practical things, like how do we think about succession planning? And I’m famous in saying that I don’t believe in succession planning.

Man.

Jensen Huang
And the reason for that isn’t because I’m immortal. The reason for that is because if you’re worried about succession planning, if you’re worried all that anxiety of succession planning, then what should you do about it? Then you break it all the way back down. The most important thing you should do today, if you care about the future of your company, post you, is to pass on knowledge, information, insight, skills, experience as often and continuously as you can, which is the reason why I continuously reason about everything in front of my team. Every single meeting is a reasoning meeting. Every moment I spend inside a company, outside a company is about passing on knowledge to people as fast as I can.

Nothing I learn ever sits on my desk longer than, you know, a fraction of a second. I’m passing that information, that knowledge—oh my gosh, this is cool. Before I even finish learning all of it myself, I’m already pointing it to somebody else. “Get on this. This is so cool. You’re gonna wanna learn this.” And so I’m constantly passing knowledge, empowering people, elevating the capability of everybody around me, so that the outcome that I seek, that I hope for, is that I die on the job, you know? And hopefully I die on the job instantaneously, you know? And there’s no long periods of suffering, you know? It’s, uh –

Well, from a fan perspective, given your extremely enormous positive impact on civilization, of course, I hope you keep going. But also it’s just fun to watch what NVIDIA is doing, you know. It’s just the rate of innovation. And I’m a huge fan of engineering. There’s so much incredible engineering continuously being done by NVIDIA. It’s just fun to watch. It’s a celebration of humanity, a celebration of great builders, a celebration of great engineering. So, it represents something special. So I hope you and NVIDIA keep going. What gives you hope about this whole thing we got going on, about humanity, about the future of humanity? When you look out, when you think about the future quite a bit, when you look out 10, 20, 50, 100 years from now, what gives you hope?

I’ve always had a great confidence in the kindness, the generosity, the compassion, the human capacity. I’ve always been extremely confident of that. Sometimes more so than I should. And I get taken advantage of, but it doesn’t ever cause me not to. I start with always that people want to do good. People want to help others. And vastly, I am proven right. Constantly proven right. And often it exceeds my expectations. And so I have complete confidence in the human capacity. I think the things that give me incredible hope is what I see now as possible, and as I extrapolate based on the things that we’re doing, what will very likely happen.

And then, you know, not for long distances, but short distances. You know, and people ask me how. Well, first of all, very soon, I’m gonna put a humanoid on a spaceship, and it’s gonna be, you know, my humanoid, and we’re gonna send it out as soon as possible, and it’s gonna keep improving and enhancing along the flight.

And then when it’s time, all of my consciousness has already been—you know, so much of my life has been uploaded in the internet. Take all my inbox, take everything that I’ve done, everything I’ve said. You know, it’s been collected and becoming my AI. And I’m just, when the time comes, we’ll just send that at the speed of light, catch up with my robot.

Thank you, Lex. I had a great time. And also, if I could just say one more thing. And thank you for all the interviews that you do, the depth, the respect that you go through with and the research that you do to reveal, you know, for all of us the amazing people that you’ve interviewed over the years. I’ve enjoyed them immensely. And as an innovator, to have created this long form, unbelievable, and yet, you know, it’s just captivating. So anyways, thank you for everything you do.

Rust players know what that means. My whole career and my family are thanks to EverQuest, so I think I won the game. And we’re idiots. We’re reading the forums, and the forums are just flaming us all the time. Like, “There’s lag on this server,” and, “Can’t log into that ser—” And that’s, that was our perspective of what was happening. And when I showed up at that show, it… One of the most emotional things in my life. It was nothing but an outpouring of love. I had believed I would never work any place but Blizzard. I loved it. It was a part of who I was and I felt I was a part of it, and I literally thought I would retire from the place. I never thought the day would come, and that was it.

Now, meanwhile, as far as the outside world is concerned, you’ve disappeared off the face of the earth, but you were actually working on a game. The following is a conversation with Jeff Kaplan, a legendary game designer of World of Warcraft and Overwatch, which are two of the biggest, most influential games ever made. He is genuinely one of the most amazing human beings I’ve ever met. In the many conversations I was fortunate enough to have with him, including while playing video games, he was always kind, thoughtful, hilarious, and still and forever a legit gamer, through and through. Of course, he’s always quick to celebrate the incredible teams of creative minds he has gotten a chance to work with over the years, and they are truly incredible.

Blizzard has created some of the greatest games ever made, games that to me personally have brought me thousands of hours of fun, meaning, and happiness, from Warcraft, to StarCraft, to Diablo, WoW, Overwatch and more. So for that, a big thank you to Jeff, to the entire Blizzard team, and to every creative mind in the video game industry, giving their heart and soul to build video game worlds that we fans get a chance to enjoy. This was a super fun, inspiring, whirlwind conversation, pun intended, with one of the most beloved gamers and game designers ever. Full of memes, lulz, wisdom, emotional rollercoaster moments, and of course, Blizzard video game lore.

Jeff left Blizzard in 2021, and has been secretly working on a new video game called The Legend of California that I got a chance to play with Jeff. It is incredibly beautiful. Set in the 1800s Gold Rush era of California, it’s an open world online multiplayer game, part adventure and action, part survival. Sometimes creating a feeling of loneliness and desperation, and sometimes just awe watching the sun rise over a beautiful landscape. It’s unlike any game that Jeff has ever worked on, and it’s a game that I genuinely can’t wait to play with all of you. You can wishlist it on Steam. Join the alpha later in March, I think, and early access is on the way.

You were first a legendary video game player, in particular in EverQuest, before you ever became a legendary video game designer on World of Warcraft and on Overwatch, which I think is a wild journey to go through from gamer to designer. But first, let’s go way back. When did you first fall in love with video games?

Jeff Kaplan
I was lucky. I was born in that golden era of coin-op. So, I literally remember the first time seeing Pac-Man. I was with my Uncle Ronnie, and he just kept feeding me quarters. I think he wanted to play, but was too scared to, so he, you know, his little nephew, he was just giving him quarters to play Pac-Man. I remember being at my brother’s graduation in Philadelphia, and they had an Asteroids machine in the lobby. That was one of the first coin-op machines I had played as well. And my brother and I would… we would try to get the high score, and we’d finally get it. But we had to go to bed early ’cause we were little kids. And then in the morning somebody else had like beat our high score. And then, you know, I grew up in Southern California in the ’80s. I was born in ’72.

So, you know, I was a kid with that skateboard BMX culture where we’d ride two towns over. We knew all the pizza parlors and liquor stores and arcades, and we just lived in that coin-op phase. That was, that was where the love started. And then you started to see things like Pong. You’d go over to a friend’s house, they’d have Pong, and it was just mind blowing, like, we’re playing this thing on the TV and it was so much fun. Atari was a big thing at that time as well. But the big one for me was actually Intellivision, because my dad was an executive recruiter, and one of his clients was Mattel. And he said, “Hey, I… They gave me this thing,” and he would get discounts or free games. And my brothers and I just loved Intellivision. Like, we would just play it endlessly.

Jeff Kaplan
And the comparison was always like, “Is this game close to what’s in the arcades?” And it was just such a golden era. And I think the, the big moment where it really blew open and kind of hit the next level was when the NES came out. And that, like, NES with Super Mario- … Was kind of gaming at the next level at that point. And I have, like, warm, fuzzy memories even thinking about it to this day. I remember we played Super Mario for weeks, my brothers and I, and then I had a friend come over, and he showed me all the secret stuff-

… in Super that I didn’t know existed at the time. And it’s… it was like suddenly, the world opened up more and games could be more. And then there was, like, a big PC gaming push that hit me. My parents ran their own business. Like I said, my dad was an executive recruiter, and they bought an IBM. And this is, like, when it was DOS before MS-DOS existed. And I was so disappointed, because, like, other kids had the Amiga or the Commodore- … which, you know, they were better for gaming than the IBM at the time. And my mom, she really encouraged my brother and I. She bought Zork. You know, it was just Infocom word games, and where your imagination would take you. Like, Zork holds a place in my heart I think few games will ever touch.

And it was weird, and, like, the… Sometime in the ’90s, there was this, there was this era of what they called CD-ROM games. That’s how they branded them. And they made a return to Zork, but it now had graphics. And somehow, that just shattered everything, because the Zork you knew in your head didn’t exist anymore. Yeah, Zork was fantastic. I think it might be open source now, which I think is fabulous. But I highly recommend Zork. There was also, in those days, on the PC that worked on our IBM, was Ultima-

… which was the Richard Garriott series. And he was Lord British. We knew him as Lord British. He put himself in the game. And you want to talk about world-building. You know, there was Yew Forest and there was all the characters. And the first Ultima I played was Ultima II, ’cause Ultima I was before my time. And that series, it was this RPG group-based PC game, and the worlds were just so rich. Like, you could get on a rocket ship. You’re playing in this fantasy world, fighting demons, and yet somehow you could get on a rocket ship. And then there was just all of this sort of crazy stuff that would happen in games that are based in the world.

Like, there were bouncers in the towns, and merchants, but if you really wanted to, you could try to rob these people, or kill Lord British, you know? That was something that was super hard. And when you’re just a jackass kid, you spend your time endlessly trying to do these things over and over, and Ultima was really a profound kind of experience for me.

And, of course, that led to Ultima Online, which is a legendary game in itself, perhaps connected to EverQuest. Sort of starting to build these worlds that are massively multiplayer online video games. Can you take me to that journey? Like, as you started to get online, the MMO world. What were influential? What were fun for you?

I was busy, and I missed Ultima Online. Like, I would have had that experience. And when you hear the Ultima Online stories, they’re some of the craziest, funniest… You know, I know somebody who, they learned how to poison in the game, and then they would poison apples, then leave them on the ground, and somebody else would be adventuring, then feed the apple to their horse and kill their horse. Then they’d steal all their stuff and… You know, Ultima Online was kind of… It was the earliest grief-based experiment. Really, like, when you’re treating the humans like ants in the ant farm. That was kind of Ultima Online.

… my first, like, what online gaming, what defined online gaming for me was Quake and Doom and Duke Nukem. You know, it started with Doom and they had a… You could basically LAN. You could network with your friends or you could connect with a modem and hook up with somebody. And that was like a mind-blowing… Just seeing another entity in a video game and saying, “That’s a person on the other side of that.”

That was magical, like, that that moment happened and that person could be in another room or across town from you. And Quake kind of took it to the next level. Like, that’s where everybody knew what they were doing. The systems were more refined. And this Quake community formed with all of these, you know, great websites, mods. The community was divided into … There were two castes of players. The low ping bastards, the LPBs … and then the rest of us, you know. And I remember rolling into Quake matches, you know, on a dial-up modem with a 300 ping connection, and I thought it was the greatest thing ever. And just, just connecting with people. Like I said, the, the websites.

To this day, the only gaming website I read- I don’t read any of the news sites anymore, but I read Blue’s News. Which was like, like … Someone actually teased me recently. I linked him a story. I’m like, “Oh, did you hear this new thing’s coming out?” And I sent the link, and they’re like, “Dude, this is from Blue’s News. Like, what time machine did you just step out of?” And a guy named Stephen Heaslip… I’m probably pronouncing his name wrong. I apologize, but it was actually through that site that I learned about EverQuest.

They had those programmer .plan updates, the .plan files. And guys like Carmack would … You know, they’d post about what code they were writing or how they had optimized something, or just their personal life. Like, you know, the Ferrari talk would always happen … once they had achieved success. And there was an id programmer named Brian Hook, and he said, “I’m leaving id to go work at Verant,” which became Sony Online, “to work on this game called EverQuest.” And I was like, “How does anybody leave id, the greatest institution in all of gaming ever, to work on any other game?” I’m like, “This guy must be crazy. Or whatever this EverQuest thing is, I need to see it. I need to know what’s going on.” And if he hadn’t have made that post, I never would have checked out EverQuest.

Those early geniuses at id … Like, I wouldn’t be sitting here talking to you right now if they hadn’t had the breakthroughs that they had at the time. Gaming engines were evolving, but the level of breakthrough that they achieved with Wolf 3D, that was the first … I remember playing Wolfenstein when it was a 2D game. You’d run around. You’d dress up as a German. You’d throw a grenade.

To see it in 3D… And it’s funny. You look back at the screenshots or videos of it now, and it seems almost childish. Like, “Oh, why were you so excited about that?” And you were transported. There… It was the intimacy of first person. You know, putting the hands in front of you, holding the gun, being transported to Nazi Germany, but you’re the hero fighting the Nazis. And then the evolution. Like, when Doom came out, I’m a huge Army of Darkness fan. Like, one of my favorite movies of all time. And I was like, “This is Army of Darkness, the video game.” You know? Like, “Give me the boom stick. Here we go.” And the graphical advances… But it wasn’t just how the game looked, it was how it played.

The smoothness kept getting better. The responsiveness, the sharpness of the gameplay. You have to credit id in those days and Carmack and Romero. I … As somebody who worked on an FPS, I … That wouldn’t have existed without them. Credit where credit’s due.

And by the way, we should say you’re … As a gamer, your range is incredible. You are a legit first-person shooter gamer, but you also obviously love the more MMO world, rich, exploratory kinda game. So it’s fascinating. But yeah, there is … On the technology stack that brought something like Quake or Wolfenstein 3D to life, there’s a threshold which you pass of realism where you can immerse yourself into that world. I had the same exact experience with Wolfenstein 2D taking a step to 3D, and it was like tears in my eyes. Like, “This is incredible.” Like, my memories of Wolfenstein 3D is it was like ultra realistic. It’s silly to say now.

Writing career
Lex Fridman
It was the feeling like you were there. Yeah, what an incredible age. And some of that, the storytelling, a lot of that is the technology that brings that kind of 3D world to life. It’s incredible. But before we get too far on that tangent, you mentioned grad school. We should mention that you have a master’s degree in creative writing from NYU, and you wanted to be a writer. You told me your main influences were Kerouac, but also Hemingway, Salinger, Bukowski, Orwell. What drew you to storytelling in that medium of writing? What aspect of the human experience were you trying to put down on paper?

Well, it started with being a fan first and being inspired and reading, and it’s the, not only being transported to a different world or into a different person, but also, you know, the way that stories can touch emotions in you and trigger feelings sometimes you didn’t even know you had. And that was very appealing for me. And the big challenge with it is, and I think this is for anybody who creates anything, is putting yourself out there. To some degree, there’s a lot of ego that goes into that moment where you say, “Well, I’ve been reading, you know, 1984 or Green Hills of Stranglethorn, and I think it’s amazing. And now I’m gonna try to write something that somebody is gonna read.”

That’s a giant leap of faith. You know, that’s a moment of putting yourself out there completely, and there’s gotta be some part of that that’s ego. There’s some part of it that’s masochistic. And I think for people who want to create and build stuff, they can’t help but to do it. You don’t really have an option. That’s just how you’re wired, and you’re gonna do it anyway. And, you know, I admire people like Dickinson who can just write all the poems and leave them in a drawer to be discovered by somebody else. You know, that’s one way to go about it.

Yeah, Franz Kafka, you know, a lot of the stories he wrote, never published, and he asked for all of them to be destroyed. And then it’s only because of his friend that ignored his request that we even have many of his stories. It’s like to be that kinda… I mean, clearly, there’s some masochism there, some tortured soul. But then there’s also the ego like you mentioned. I was entertained by this story of James Joyce when he was a young man, 18, 19 declared that he’s going to be the greatest writer of the 20th century. And he turned out in many, in the eyes of many to be one of the greatest writers of the 20th century. But there’s, like, millions of kids just like James Joyce, writers, they’re declaring exactly that, that turn out not to be.

But that is in some cases, in many cases, maybe most cases, you have to have that ego- … to say, “I’m gonna…” Yeah, right. “I read 1984,” “and I’m going to write the next 1984.”

Yeah. And I do think ego is a big part of it. It’s one of the many lessons I’ve learned. Hearing your Kafka story is funny, because fast-forwarding to how my writing career ended- … I literally threw away everything, I mean, in a dumpster. I used to keep copious notes, like journals, my writing journals, everything I ever read, every story idea. I probably had 20 volumes of just handwritten notes. And then I also kept personal journals of just, you know, to keep the writing habit up of just, you know, what happened in my day, how I was feeling, all of that. And then either digitally or typed, I had all of my manuscripts, and I threw it all in the dumpster.

Yeah. It was—I think it was necessary. It was necessary. This is like rationalizing it after the fact, you know, which is easy to do. You know? But at the time, I think I was so broken and so defeated with failure that I needed the moment. It was like throwing in the towel for a boxer, you know? It’s that moment of like, “I’m not gonna win this fight, and you need to move on from it.” And if there was any element of that sitting around, I’d be tempted to try again or bring it out of the drawer 10 years later.

It was hard. I had moved from New York. I did the most terrible dumb thing that I knew I was doing at the time. I had a really great group of writer friends from grad school in New York, and I think writing is a very lonely, solitary thing. But weirdly, writers kind of support each other and just, “Who do you give the story to?” You know, you don’t wanna give it to your mom or dad, you know. You kinda wanna give it to somebody who’s gonna really punch you in the nose and tell you what’s wrong with it. And I had left that writing circle to move back to California.

So I moved back to California, and I did it for a girl. And I think within two months of moving back, we were broken up. So… And I knew it when I was standing in my studio apartment when it was empty in New York and I was about to close the door for the last time. I had that, like, you know, little me on the shoulder saying, “Dude, what are you doing?”

“This… You’re making one of those epic life mistakes that is gonna come back to haunt you.” And I ended up alone in California, and I think it was a good three years that I structured my life where I was gonna write for eight hours a day, because it’s that writer’s habit. Like, you have to just force yourself: “This is a job. This isn’t a hobby. Whether I like it or not, rain or shine, sick or healthy, I’m gonna write for eight hours a day.” And I did. I was fortunate. Like I said, my dad had his company and he hired me as a research associate. So I was calling up, generating name lists for a recruiting company, and I would take… Whenever there was East Coast assignments, I would take those so I could start at like 5:00 in the morning.

And I created all this space for me to write, and I just… I had a dog named Jack- … who was… He was a Jack Russell Terrier. And so everybody’s like, “You’re a writer, you named your Jack Russell Terrier Jack.” I’m like, “Because I named him after Jack Kerouac.” “It’s poetic and epic,” and-

Lex Fridman
Yeah, of course.
Yeah, of course.
Jeff Kaplan
… I just looked like a dumbass, but- … it was just me and this dog. And I was writing, you know, all that time intensely. And this was mid to late ’90s, so even though the internet existed, email was very primitive and you had to send a manuscript off, like printed paper- … to all… Like, I was trying to get short stories published in literary magazines, and you had to send an envelope with a return self-addressed stamp. So it was expensive, too. Like if you didn’t have money, you were just… There was a cost to it- … to every single one of them.

Yeah. And the, like, big thing that you were hoping for was that the editor would write you a note with the rejection letter. Like, um-
Yeah. And the, like, big thing that you were hoping for was that the editor would write you a note with the rejection letter. Like, um-
Lex Fridman
Keep going.
Keep going.
Jeff Kaplan
Yeah. And you’d like cling onto this. Like, it was like, “Oh, Glimmer Train said, you know, showing promise.” You know, and you just hang onto that for like a week, you know, pretending like that was… But it was just soul-crushing. And I really stuck… And I became more and more isolated. Part of that was leaving that group of writing friends in New York. I’m prone to just introversion anyway. The type of person I am. Breaking up with the girlfriend at the time. I just sort of fell into that world of, like, all I was doing was writing. And it broke me. Like, I went into very deep and heavy depression. I drank too much. I really had a problem with alcohol. And all those things compounded into just deep, deep depression. And I don’t… There wasn’t like a magic rejection that broke me.

Jeff Kaplan
That would have been epic if like- … someone out there is like, “The dude who…” “I’m the dude who broke Jeff that one day.” But I just had a moment where I said, “This is gonna destroy me.” And… Like, I don’t want to be discouraging to anybody, because I really do believe, like you hear it so much, like, “You have to work for your dreams, never give up.” Like, we’re trained this way. Like, “Never give up.” The universe… Actually, maybe not the universe. A group of editors at literary magazines across the United States was telling me it was time to give up as a writer, like I wasn’t cut out for it. And I stopped.

Yeah. And I think, rightly so, our parents, our coaches, our mentors train us not to give up. And I think a lot of us take pride in that, “I’m never gonna give up. I’m gonna do this come hell or high water.” And sometimes there’s that reality, especially when you’re now in your mid-20s, where you have that moment of like, “Am I really gonna be this? Like, am I ever gonna sort of find the light here?” And, maybe, and it’s so hard, it’s so hard to have this moment, “Maybe this isn’t my calling in life,” especially when you don’t know what the next calling is gonna be.

Lex Fridman
That’s so painful. It’s ’cause you’ve invested so much of yourself, of who you are, of the dreams you’ve had, of this just whole conception of yourself, and you’re watching yourself slide down in terms of becoming isolated, suffering more and more. And then you just have to somehow figure out how to get out of that. And it is true. In that situation, the way to get out is the dumpster. Is to cut it off. Is there advice you can extract from that? There’s a lot of young folks who are in that same situation.

Jeff Kaplan
Yeah. I, this is one of those hindsight things where, you know, having gone through it and ended up okay on the other side, which you don’t know at the time, you know? When you’re a young person in your late teens or early 20s, there’s so much pressure on you. And I really think adults don’t help. You know? Every time you run into the younger nephew or whoever and you start to say things like, “Oh, what’s your major? What are you gonna do with that?” “What do you wanna be?” It’s such bullshit to do to a human being. You know?

Lex Fridman
You’re so lost in the world. I mean, most of us are lost our entire lives, but especially in your 20s, you know, like, you’re lost. So the questions like, yeah, “What are you doing? What’s your major? What’s the career?” And so on, that’s not the point, man. I’m trying to move through the world, I’m trying to run through the world to find the thing that sparks my heart, to find the passion, to find what I’m meant to be on this earth for. And there are really, I mean, that is a real hero’s journey of searching as a young person. That’s a real, like, you know, all the adults, with their wisdom, they’ve stopped searching often. They’ve done the lazy, the comfortable thing. They found their thing.

Jeff Kaplan
It’s, there’s confusion, there’s pressure. Like, the pressure we exert on younger people for having it figured out is insane. So the advice that I always give, and it sounds so stupid, like this sounds really trite, but focus on what you wanna do, not what you wanna be. The pressure that society kind of puts on us is, you know, “Oh, do you wanna be an astronaut? Do you wanna be a firefighter? Do you wanna be a writer? Do you wanna be a game maker?” And I think we get lost in the trappings of, like a vision of what that role is- … and how to perform as a fake actor in that role. Versus when you’re off the clock and no one’s asking you any questions-

EverQuest obsession
Jeff Kaplan
Gradually and suddenly. So when I had that fateful moment where I just sort of gave up with writing, I had these days where I’d structure eight-hour chunks of just, this was writing time, you know? I’d sit solitary typing. All that was gone. And, you know, I could still support myself, which was nice. And then I had this free time and I wasn’t spending it with anybody, I was just alone. Me and the dog, Jack. And I just poured it all into EverQuest. You know, I, it was 1999 when that game came out. And I had a friend, Victor, like kind of a lifelong friend. One of the few friends I had who played computer games, ’cause there was a stigma to that.

Jeff Kaplan
You know? It wasn’t, you didn’t walk around telling people you played games. They thought you wasted your time. And my friend, Vic, had bought EverQuest. I’m like, “That’s that game that that guy Brian Hook went to work on. Is it good?” And he’s like, “Yeah, you gotta play it.” And the moment I logged in, I was just transported. It was the world of Norrath. And it wasn’t just the world itself and how it looked, I thought the game was gorgeous, it was the mechanics, you know, that I was this halfling rogue that, you know, had to go out and adventure in the world, and when I killed stuff, I got experience, and I needed better loot to kill more stuff to get more experience. And the sort of draw of progression in the game was amazing.

Jeff Kaplan
I, and I just lived my life of, “I can’t wait ’til the next time I log in.” There was a lot of escapism going. It wasn’t all healthy. When all was said and done, when I finally had quit EverQuest three days later, you could type in the command /played to see how much played time you had. I had, I think it was like 272 played days in three years. So you start to do the math on like, how much time- … in those three years I was living in that world. It was… it was kind of insane.

Lex Fridman
Well, that’s over 6,000 hours- … of gameplay. Wow. So here going to Perplexity, EverQuest is a long-running 3D fantasy, massively multiplayer online role-playing game, MMORPG, set in the world of Norrath, as you were saying. First released in March 1999, it is an online role-playing game where thousands of players create characters, group up, and explore a persistent shared world. It’s widely regarded as one of the foundational MMORPGs, helping define raid content, guild systems and 3D online worlds. That’s the other component of it. There’s… It’s all humans and they group up- … and they raid together in the game.

Jeff Kaplan
Yep. In the context of EverQuest, raiding is usually around 30 people or more getting together to conquer something that you couldn’t beat otherwise. And to do successful raiding, you usually needed to join what in EverQuest everyone referred to as an Uber Guild. So I had this great pride in my EverQuest journey that I… Most of the time leveling up I was unguilded or I was in like a role-playing guild with rogues only. And it was when I got to Level 50 in EverQuest, which was the top level, I got invited into this guild called Legacy of Steel, which on our server was the top. Every server had a top guild.

Jeff Kaplan
And I was on a server called The Nameless Server, and the top guild was Legacy of Steel. And that, the thrill of getting 30 people together to go see if you could beat, you know, Nagafen, who was the fire dragon, or Vox, who was the frost dragon, and needing perfect coordination to pull it off, it was insane how fun. Like, you would literally scream out. You’re alone in your room at home- … but you felt like you were there with these people and you would audibly cheer out when you won, and you’d feel depressed when you lost, and it was a game of high highs and low lows, and it did everything right. It was amazing.

Lex Fridman
So that was a big leap for you to go from the proud lone warrior to a member of a guild, an Uber Guild. And then there’s that epic story of you rising to the top to become the leader of this Uber Guild.

Jeff Kaplan
The leader… Yeah. So organizing people in an online game like EverQuest is like herding cats- … ’cause, you know, everyone has their own will. Some people are loot motivated, some people want the guild to do well, some people are just lonely and want people to hang out with. And there was also a lot of depression in the EverQuest community. It was something I suffered with, but a lot of people, you know, anytime you’re feeling sad or down, you’re looking for escape. And one of the great things video games brings us is escapism. And escapism isn’t always bad or negative- … but when you sort of abuse it to escape your real life problems, it’s bad and negative.

Jeff Kaplan
Yeah. And what’s weird is you enter the cycle where being with other people gives you comradery and relief and makes you feel like you’re not doing so bad in life, but you can quickly enter a cycle of… But then you’re withdrawing from life and it makes you feel that way more to where you can only get the fix from the game at that point. So it’s… Psychologically, there’s a lot going on there.

So it’s… Psychologically, there’s a lot going on there.
Lex Fridman
And so you had to work with all of that. You have to get a bunch of people together to do a raid, who are all human beings going through complicated psychological journeys of their own. Some are talking shit, some are just quietly lonely, just looking for some loot.

Jeff Kaplan
In the late ’90s, everyone was talking shit. You know what I mean? Like, the gaming culture was just a different thing back then. But it was a great group. It was super fun. It was people from all walks of life. And to coordinate these people, like you just had to repeat everything like 200 times. Like, “Okay, we’re gonna port from North Ro. Everybody get to North Ro.” And then you’d have to repeat that for like six hours-

… to have any chance of like 20% of the people showing up in North Ro. And I sort of like… At first I joined the guild, I was just like the bright-eyed, bushy-tailed. Like, I was like one of the few rogues in the guild. I just wanted to be helpful. I really admired the people running the guild. Like, we had a great guild leader. And it was just a really fun experience. And, you know, the guild leader one day just disappeared. Like, he quit and he was going through, you know, his own thing, and that’s what would happen in EverQuest. Like, people would just kinda disappear all of a sudden. There wasn’t a, “Hey, in about a month, I’m gonna stop playing because I’m starting this new job.”

Did you miss them when they disappeared? Like, we, we should say that most of the people, maybe all of them, were anonymous. So you just- …have a username, and you don’t really say who you are in real life.

Absolutely. In those days, there was a great stigma to mentioning your, any real-life info. You just kind of kept it all really close to your chest, and you never knew who was male or female. You kind of assumed everybody was male.

Yeah. Yeah. The funny part for me with EverQuest is, you know, you play a game as much as I played EverQuest, and people are like, “You threw years of your life away.” Like, “You can’t win a game like that.” And I’m like, “I don’t know, like, sitting here today, my whole career and my family are thanks to EverQuest, so I think I won the game.”

Your life will be on the Wikipedia page somewhere that says, “Well, here’s an example of somebody-” “… why video games are awesome.” Yeah, I mean, some of it… I should mention this as an aside. For me and many people I know, yes, it’s hundreds of hours, but some of the happiest hours and days of my life. Like, looking back, it all worked out. During it, you are pretty low, and you think, “What am I doing with my life?” All that kind of stuff.

But, like, looking back, just the all-nighters you pull playing a particular video game, allowing yourself to really fully be immersed, seeing the sun come up—and by the way, many of those games, for me, were Blizzard games. It’s just an incredible thing that video games have been able to do. I think, you know, it used to be, and still is somewhat the case, that books do that same kind of thing. They- …they take you on a journey. But video games, for a long time, you’re right, they had a stigma. Like, I couldn’t tell people. I felt like I was doing, like, heroin or something. Like, I felt like I was doing this secret, dark thing. It usually is in the dark. There’s just a secretive nature to it, like I’m doing something really dark and shady.

They- …they take you on a journey. But video games, for a long time, you’re right, they had a stigma. Like, I couldn’t tell people. I felt like I was doing, like, heroin or something. Like, I felt like I was doing this secret, dark thing. It usually is in the dark. There’s just a secretive nature to it, like I’m doing something really dark and shady.
Jeff Kaplan
It wasn’t mainstream.

Lex Fridman

It wasn’t.
Jeff Kaplan
It wasn’t accept-… There was a stigma to it. And one of the weirdest parts of that is, you know, I mentioned, like, you could type in the /played in EverQuest. Well, if you did the /played on how much TV people watch, what would that look like? It would blow- …6,000 hours out of the water, easily. Well, it… 20 years ago it would have, you know? Not today.

Now it’s the phone, yeah. Yeah. But then, it is hard to say goodbye to that world. Those are also really painful times. How hard was it to say goodbye for you?
Now it’s the phone, yeah. Yeah. But then, it is hard to say goodbye to that world. Those are also really painful times. How hard was it to say goodbye for you?

To EverQuest? It was really hard. And there were times where you try to quit.

Lex Fridman
Oh, you took a break sometimes?
Oh, you took a break sometimes?
Jeff Kaplan
Yeah. You think you’re quitting for good. You’d have those moments of, like, “I’m doing this too much. I need to move on in life. I’m gonna put it down and walk away, and hopefully not come back.” And there were times where you did come back. When I finally did leave EverQuest, it was actually extremely easy, because I was psychologically done with the game at the time. It was not shortly, but not too long after a new expansion had come out. At the time, it was Shadows of Luclin.

Which didn’t speak to me like the expansions before. Like, the one before that was called Scars of Velious, which was an amazing expansion. And I had gotten the job at Blizzard, and I guess I’m just an obsessive person. So all the time and energy that I had put into EverQuest, the second, you know, the second, my first minute started at Blizzard, that was my new obsession.

Getting hired at Blizzard
Lex Fridman
So speaking of which, you have to tell the epic origin story of how you got the job at Blizzard. As we said, you were this legendary gamer, and now legendary troll, on EverQuest. Username, Tigole. You gave a lot of edgy feedback to the devs, telling them in now famous… There’s several rants. There’s a famous one where you tell many of them to do a bunch of things, including to pull their heads out of their asses. You were loved and respected because you gave a lot of specific ways that the game could be improved. And that’s an important thing to say. You weren’t just talking shit. You actually really loved and cared for the game, and you gave them, in the language of the time, advice on how to improve their game.

And it’s funny, because, like, you look back to those messages, it’s inspiring to me. It should be informative and inspiring to a lot of people, because you’re really, legit, full-time talking shit. And now, and you always have been, like, one of the kindest, most loved human beings in the entire gaming industry. Anyway, how did that lead to you getting a job at Blizzard?

So when the first guild leader left, Legacy of Steel, the founder… He, he was a guy named… His online name was Dread. That was his name. He left, and our guild was kind of in this listless spin for a while. And eventually, somebody stepped up and took his position as guild leader, and that person’s name was Ariel-

… who was this blonde wood elf warrior female, who always refused to wear a helmet because she thought their character was so pretty, wanted to show their face all the time. So Ariel was a great guild leader for us, and made me like an assistant guild leader, raid leader, officer type in the guild. And over time, Ariel got busier and busier, and, you know, would send me messages like, “Hey, I’m not gonna be online, you know, tomorrow,” or, “I’m not gonna be online tonight. Can you run the raid? Can you run the raid?” And running the raids was very natural for me. And it was my first experience with leadership in my life, of like how do you motivate people? Like, what does motivation look like? What does discipline look like? How do you inspire people?

Uber guild leader. Best guild on the Nameless server. So as time went on, Ariel became busier and busier, and then one day, they contacted me and we were having this like whisper back and forth, and they said, “You’re gonna have to take over the guild. I’m just too busy.” And then it came out later … Well, let me back up a second. I started fooling around … Like around this time Half-Life 1 had come out, and with both Duke Nukem and Half-Life 1, one of the incredible things that those companies did back in the day was when they shipped the game, they shipped the editor on the CD.

And if you were curious enough, you could like fire up that editor and fool around with it. So I made a- a Duke Nukem level, and you’d send it off to like those UK programming magazines, and you know, you’d get excited because your level was in, you know, some random magazine. And then I started making like Half-Life levels. And Ariel had stepped down as guild leader. I had become guild leader.

And then at one point, Ariel contacts me and says, “Hey, you know, you were talking about those Half-Life levels you made.

So you actually like burned it onto a CD and stuck it in the mail. So I put my Half-Life levels, I sent them to Ariel, and he says, “You know, my name’s Rob. I’m a designer at Blizzard Entertainment.”

“I hear you’re in Pasadena ’cause you mentioned it.” You know, I would write about, you know, the Rose Parade and all these things on our website. You know, I kind of … It was blogging before blogging existed, so he knew I lived in Pasadena, and he’s like, “Irvine’s only an hour away. Why don’t you come down, see Blizzard, and you can also meet …” and he names like four people in the guild. And I’m like, “They all work at Blizzard too?” He’s like, “Yeah, we’re all Blizzard.” And it was so weird because during that era, I didn’t have a lot of money. It was not like … Kind of nowadays it feels like everybody plays every game, but you had to be selective. So like I never bought StarCraft or Diablo or Warcraft.

No, I was freaking out in a different sense. I’m like, “Am I gonna get mugged when I-” Like, “Who are … Is this a scam?” Because you didn’t meet people off the internet. So I drove down there. I ended up … There was Rob Pardo- … who at that time was the lead designer on Warcraft III, and he was Ariel. You know, so okay, it wasn’t a woman after all. It wasn’t this blonde wood elf. You know, I don’t know what you expect at that point.

It was Rob Pardo. To this day, a great friend of mine named Scott Mercer was the enchanter in our EverQuest guild, a guy named Dalomin. There was a guy named Roman Kenney who was like this totally psychotic wizard who played in our guild. And I had lunch with these guys, you know, we just went out to Irvine to like a restaurant. And, you know, forgive me for the misuse of the phrase, but it was like my coming out moment. And we talked about games having that stigma and being embarrassed about who you are and what you like. Like I, up until that point, I would never tell friends, family, like, “I love games. I’m playing this game EverQuest. It’s so cool, we just killed a dragon.” And so you were hiding this part of your identity.

And I’m out to lunch with these guys in Irvine, and we’re talking about dragons and swords and, you know, raid tactics and talking shit on all the people in the guild. And I literally had this moment where I felt like myself for the first time. I just felt so comfortable, and that was an eye-opening moment. And after that, after that lunch happened, he invited me for a couple more lunches down, you know, just… I just saw it as like, “Oh, now, I’m…” You know, I made friends with these people online. Now we know each other in real life, and they happen to work for this game company. And at another one of the lunches, they invite this troll warrior to have lunch with us, whose name in the game was Barfa, the Troll Warrior.

And Barfa wasn’t somebody who played with us all the time, but kind of like Ariel got into the guild kind of on the side. You know, it was one of those like inside invites of like, “Who’s Barfa?” “I don’t know, but Barfa is in the guild now.” And there was at the time, it was a new dungeon called The Hole, and we had never done it before. And we jumped down in this hole, and we’re doing this whole dungeon, and everything goes wrong, as it’s prone to do in EverQuest. And the whole guild escapes except for Barfa, whose troll character’s so big, he can’t jump out of the exit.

And I hand the potion to Barfa, and I say, “Here, use this. It’ll teleport you out.” And I’m a rogue, I can just stealth and get out of the dungeon on my own. So I saved Barfa, not really knowing who Barfa was, and I did it with a very expensive potion. Mm-hmm. Having lunch, Rob introduced me, “This is Allen Adham. He plays Barfa.” Mm-hmm. I’m like, “Oh, Barfa!” And we, you know, he has a… “You saved me in The Hole that time.” Well, it turns out Allen was the founder of Blizzard, and he was the head… He was sort of the head of everything at that time. It was Allen, Mike Morhaime, and Frank Pearce. And what I didn’t realize what these lunches were, like I just loved them because I felt like I was myself.

I felt true happiness being surrounded by these, you know, people who were talkin’ about video games and I felt comfortable around. And one day, Rob logs into EverQuest. He wasn’t playing much at the time, and he said, “I want you tomorrow to check the Blizzard job site.” Mm-hmm. I’m like, “Okay, like, I’ll check the Blizzard job site.” And they had announced World of Warcraft, and posted on the job site—mm-hmm—was the job for an associate quest designer. And the funniest part of it was, I forget if it was a requirement or a plus in the job description, but they’re like, “We really want somebody with a creative writing degree.” Hmm. And I’m like, “You guys set this up for me.” Like, they were just looking…

And it was that hindsight moment of like, actually, these guys were just interviewing me for six months. And they were actually friends, and they were really cool about it too. And I just had the fuck it moment like that, that job opened up. I applied with all my heart, you know? Like, they had a bunch of quest writing on it. And then I went through like a pretty hardcore six-month recruiting process because they never hired designers from out of the company. Traditionally, designers were promoted from within Blizzard. Either they would like transfer out of other disciplines, or they would come from quality assurance, tech support. So hiring somebody off the street was kind of a big deal for them, and they really put me through a grilling.

I met with… It was the first time I met Chris Metzen who is maybe the most inspirational, creative person on the planet. And you instantly… They paired me… They did this interview pairing. There were these two guys. It was Kevin Jordan who was one of the original designers on WoW. Really, he doesn’t get enough credit for his contributions. He was one of the earliest class designers, PvP designers. But he’s a really quiet guy. And they paired him with Chris, and Chris just owns the room, you know? Chris, you could just sit and listen to him. He’s so creative. He’s so passionate. And the way he articulates things, like you just instantly become a fan of Chris when you’re around Chris.

And Chris, Kevin, and I go to lunch at this Italian place that was across the street from Blizzard, and I remember… Chris made a stop to buy cigarettes, you know, on the way to the interview. And then every other word out of Chris’s mouth was like, “Fuck,” and, “Shit.” And I’d come from this whole, like, corporate culture from my dad’s recruiting business, where I’d never imagined somebody would curse in an interview, or stop to buy smokes. And again, it was like, “I’m around my people.” Like, I never smoked, but just, you know, being around people who didn’t care about-

Jeff Kaplan
… what the corporate norms were was so inspiring. And then my last interview was with Allen and Rob, and a great programmer named Bob Fitch. Like, I think he’s one of the first five developers at Blizzard. And they took me to an ARCO station that had a Jack in the Box. You know, how, like- … sometimes they’ll combo? It was like ARCO Jack in the Box. And that was my final interview at Blizzard, was at the ARCO Jack in the Box. And I remember thinking to myself, “These guys just brought me to a Jack in the Box that’s in an ARCO station. I need to work here.” Like, this is… “These are my people.” “This is where I belong.” Like, it was the greatest thing ever. And so, yeah, that’s my crazy journey to Blizzard.

Lowest point in Jeff’s life

There were a lot of really low points. I started drinking a lot, and alcohol was something that I really wrestled with until my early 30s. And one of the things I’m most proud of today is sobriety and having been sober for such a long time now. And I remember I would like buy a bottle of Old Grand-Dad and- … like, drink the whole thing by myself, and then watch the Oscars. I remember I was … Of all things, I’m watching the Oscars, which is just such a fake, bullshit environment.

But I was like… You know, I was really drunk and all those people seemed so together and successful and polished, and I just… It made me… It was that contrast that made me feel like such a failure.

It’s not just checking a checkbox of, “I went to therapy.” It’s about finding somebody who sort of helps you get out of whatever rut you’re in, in a way that’s healthy for you. And I tried antidepressants, but I hated… I just hated taking pills and feeling like something was in me, and making me feel different. I- I never responded to it. And then the hardest thing, you know, which I’ve never mentioned to anyone, and is- is hard for me to talk about, but eventually I went through ECT, which is electroconvulsive therapy, shock therapy. And that broke me out. And I would never endorse that as a miracle. That was… I was at such a low point that people were very worried about me and my wellbeing-

You would succeed on your own or you would fail on your own, and that was very attractive to me. And the thought of creative collaboration was actually off-putting. I’d spent all four years of undergrad interning at Universal Pictures, ’cause I thought I wanted to be in film, and it was such an unhealthy creative collaboration in the film industry.

It’s a very, you know, I look up unhealthily to the film industry and admire it and, you know, grew up with all these legends who had come from there. But it’s like a caste system. And I was on the bottom of the caste system as an intern, and I was seeing how the other people who were low caste in the film industry were treated, and it was just horrible, you know. But games was different. Games was very flat. It didn’t matter if you were the CEO or the boss, like, the way Mike and Allen carried themselves with, you know, me, who was an associate game designer, you felt like an equal. And I think it… Not just the camaraderie, but the part that shouldn’t be overlooked is the work itself and the work ethic. That’s what really pulled me out.

Specifically, I will be designing quests for World of Warcraft, Blizzard’s MMORPG based on the popular Warcraft series. In addition to my duties as quest designer, I will also be expected to contribute to helping design the end game content for World of Warcraft. The reason I’m sharing this information, besides the fact that I have a masochistic love of reading rants and flames about myself, is because I know that the fans of this site are hardcore MMORPG players. The readers of the site have also come to know my personal opinions on what constitutes a fun gaming experience versus what feels like a complete waste of time or poorly designed encounter.” Wow, you’re very eloquent in this post and without too much shit talking.

“I know exactly how to fix this video game and all video games and-” But there’s brilliance behind that. There’s a passion behind that. Like, when you’re a gamer and you really put in the hours in a game like EverQuest, you understand what makes for a compelling experience. You don’t, at that time, understand how much hard work is required to create that experience and how much uncertainty there is, how difficult it is, how many trade-offs there are. How your designs, when they actually are brought to the world and are experienced by thousands of people, millions of people, they are different from the vision you had for it. So all those elements you don’t know, but you have to have that ego in the beginning, right?

And it was so funny because you drive up and, like, everything was very serious and corporate, and then outside of the Blizzard offices, it’s everybody is wearing black T-shirt and shorts and throwing frisbees and playing Hacky Sack and on scooters and skateboards, and you’re like, “Okay, that’s where, that’s where Blizzard is.” So it was that environment. I remember walking in the door and thinking like, “It feels like I’m walking into a dorm room-“

“… ’cause it was just posters on the wall.” And there were actually, like people would have futons because they’d be sleeping because we would work so much back then. But the vibe was… It was very small. Like Blizzard, the day I joined in May of 2002, was fewer than 200 people, and that included… There was a whole group up in San Mateo called Blizzard North. So Blizzard South, the Irvine group, was responsible for StarCraft and Warcraft, and there were two development teams at Blizzard. It was called Team One and Team Two at Blizzard South. Team One was revered. These are the RTS guys. They made, you know, StarCraft, Warcraft II, and they were, at that time, they were working on Warcraft III.

Team Two was kind of the red-headed stepchild. Like apparently, before I joined, they had tried to spin off a second team multiple times and failed, and then they finally decided they were gonna make World of Warcraft. There was a game called Nomad. I don’t know what that game was exactly, but that was what Team Two was working on at first. That got scrapped, and Allen steered the team towards World of Warcraft. And there’s an amazing designer named Eric Dodds. He’d go on later in his career to be the game director of Hearthstone. Him and Ben Brode basically were the core designers behind that. But Eric and Kevin Jordan were these two key designers working on World of Warcraft for Team Two, and then you had this tech group that was headed up by John Cash.

So, and then he saw me, and he was a huge EverQuest player, and he was like, “You’re the guy who runs Legacy of Steel.” I’m like, “You’re John Cash.” We had that moment where we kind of fanboyed out on each other. And it was just… The vibe was so cool there. Like, there were very few producers. So a game team, there are five core disciplines that make a video game. You’ve got engineers or programmers who are writing the code. You’ve got the art team that’s making all the visuals for the game, and that spans everything from like 3D modeling, characters, environments, to also animation, tech art, you know, making it all work.

You’ve got game design, which some companies don’t have design. The artists and the engineers do it. Valve famously has very few designers because everybody there is a designer. But in companies where design is a discipline, which it very much is so at Blizzard, game designers are sort of the creating the game experience people, you know, setting up all the systems and content in a way that gets the player to navigate through the game.

Yes. So game designers, there’s a spectrum, like same with art, same with engineering, of roles within game design. Some are more heavy on the systems side. So like any game that you’ve played where loot drops- … you know, Diablo IV, World of Warcraft, you know, Escape from Tarkov, whatever. If there’s loot dropping, a designer has planned out very carefully what drops where and at what percentages. That would be like a systems designer. A content designer is somebody who’s gonna make quests or write storylines, or there might even be a narrative designer, which is even more focused on a story. But designers, you know, run the gamut, and then you’ve got these jack-of-all-trade designers that can do it all.

… you know, audio, which is comprised of the sound designers and composers. And there are two things, I think there are two things that no one realizes how much they bring to a game until they’re missing, and that’s audio and lighting. Because most of the time, we’re playing without these things, and it just feels a little off and wrong. And when you have a great lighting artist or you have a great composer or sound designer, like, it… the experience. You’re just tapping into these senses that you wouldn’t otherwise. But that’s who comprises the game team.

Yeah. Lighting, you’re gonna have lighting under the art team, but they’re gonna be best friends with the graphics programmer. And, you know, like I mentioned with design, there’s this wide spectrum on the engineering team. You have some guys who are like architectural geniuses who are coming up with, you know, the server client model or the networking or whatever. Others are more, like, gameplay focus. On Overwatch, we had an audio programmer just doing nothing but audio hooks for the audio team. And on every game team, you’re gonna have graphics programmers who will work with people like the lighting artists or the environmental artists, character artists on shaders, and basically any way to make the game. They’ll always ask, “What’s your vision?”

What are you trying to get it to look like?” They’ll want an illustration of what should the world look like, and they’ll be the ones who say, “I know how to write code that will let you do that.” So you partner a great graphics programmer with a great lighting artist, and that’s… That’s actually the creative tension behind games and what makes game teams so unique, is if we were to line them up on some crazy spectrum on one end, you’re gonna have the artists who… They’re creative, dare I say emotional- … you know, they are artistes on that end. And on the other end, you have the most logical, brilliant programmers who their minds just work very differently from the most creative art-

Like artists could be sitting, you have a meeting with them and they’ll just sit illustrating. If there’s any piece of paper, they’re drawing on it. And programmers, you know, they’re just so brilliant and organized in their thinking and everything is so logical. And then in the middle are people like the sound designers, the game designers, and the producers. They’re kind of a little bit in all those fields, but it’s the brilliance of taking people who are so vastly different in their interests and talents, but aiming them at that shared goal or that shared vision of the game that, like, really makes something special.

And there, I mean, you showed me the size of the team for World of Warcraft, but you also are well known for working on quite small teams to create these incredibly huge games. What is the power of a small team in this kind of context where a lot… there’s that creative tension? Is it because a small team avoids maybe the compartmentalization, like the modular where the artists now have their own wing building where they never talk to the engineers, that kind of thing?

Absolutely. I mean, you hit the nail on the head. The bigger the team, the more you become a cog in the machine. And on a small team, the way I like to describe it is you get to have a loud voice. If we’re a small team, let’s say we’re gonna make a game and it’s at sort of the incubation period of a game and there’s only 10 of us, all 10 of us are in the room for every decision. You know, I’m not a server networking guy, but I’m in the room for that discussion. I’m not an illustrator, but I’m gonna sit in the room when we decide what the art style looks like. As soon as the team starts to grow, we become compartmentalized.

Jeff Kaplan
It’s exactly like you said. And there’s a weird thing that happens that’s just kind of a human nature thing. The less you interact with somebody, the more you sort of become alienated from them and vilify their point of view. You tend to look at what they do and say with skepticism- … rather than trust and belief in them. And I find on smaller teams where we all know each other’s names, I know what everybody’s working on every day, they know what I’m working on, everybody can talk to each other, there’s none of that stereotyping of a discipline. On big unhealthy teams, you start to say things like, “Well, the artists just don’t get it.”

Jeff Kaplan
“They don’t understand what we’re trying to make.” And when you back up and you think about the statement that you just said, it’s like… such an asshole statement. Like, really, all the artists don’t get it? Like, that’s… A, that’s not true. B, that’s sort of demeaning to them. Like, they signed up for the… This is their life’s work, too. This game is gonna be as much theirs as it is mine. So who am I to say a statement like that?

Lex Fridman
Yeah. It’s harmful to a discipline to think that you understand the world. Most other folks don’t, and you have nothing to learn from them, really, and they’re deluded in some kind of way. That’s so powerful.

Jeff Kaplan
Fast-forwarding a little bit, when we formed Team 4 and… Which went on to make Titan and ultimately fail, and then that got rebooted as the Overwatch team, the idea that I tried to get through to the team was to make an assumption. And really, like, Blizzard is one of the top game developers in the world, and we were very fortunate when I was there, and I imagine it’s this way today, that we could recruit whatever talent we wanted. The best of the best wanted to come work at Blizzard. And if you sort of go through the paces of that and say, “Okay, when we recruit somebody…” Let’s say we’re recruiting an artist to make props.

Boxes, chairs, whatever. That is the best prop artist in the industry. That’s who’s gonna show up on our doorstep, so when they show up here, we should treat them like the best prop artist in the industry instead of starting from a place of doubt and cynicism. So, when that person speaks up and says, “I think…” Like, with Overwatch, for example, “I think we should do this.” You know, “We should do X instead of Y.” Instead of saying, “Well, I’m a believer in Y, why are you against my idea X?” You should take a moment, have a deep breath, and say, “Man, the best prop artist in the industry is suggesting something.” Why don’t I listen to it?”

Lex Fridman
I actually do it for myself, like this kinda thought framework or thought experiment. Whenever I’m talking to a new person, especially if I feel, myself, a little bit tinge of that feeling. Usually, it happens with, like, a really young person, like an undergraduate student or someone like this. I pretend that they are the smartest person in the world in my head, and then not… Like, it puts me in the mode of, like, assuming I have a lot to learn from them, and it helps. You actually, like, really listen. I literally think they’re the smartest, wisest human on Earth. It helps me.

I had that, like, I think… You know, I’m no expert. I’m a game designer, so, like, as much psychology as I know is how to manipulate people into having fun, hopefully. Like, I don’t know, I don’t have an important job.

Jeff Kaplan
And as we kind of go through our life journey, the insecurity also changes. So, like, some people, for example, use their insecurity to rip other people apart. Some people destroy themselves through their own insecurity. Some people destroy everybody with their insecurity. But I had that moment as a young lead, when I first was made a lead on, like, World of Warcraft, where I felt it was very important to be right and to, you know, be shepherding the correct idea. And I actually got pulled aside. Like, Pardo and I had a meeting with a couple people who weren’t game designers, and it’s always tricky as a game designer because constantly everybody is throwing ideas out on a game team. Like, there’s no shortage of ideas ever.

Jeff Kaplan
And we were in some meeting about something, and these people kind of threw out these ideas. And I wasn’t mean to them, but I very kind of systematically, like an insecure, you know, ego-driven new lead would do, I kind of, “Let me tell you why that’s wrong, and let me tell you what we’re gonna do instead.” And after the meeting, you know, Pardo pulled me aside, and he said, “You’re a very smart designer, but you shouldn’t do what you just did to those people. You should always listen to what people have to say and try to make their ideas work.” And I just…

Over and over, I was like, “Okay, anytime an idea comes my way, let’s try to make it work.” And it went from this kind of thing that I didn’t believe into to actually, like, a core part of who I am today as a leader, as a game designer, as a game director. And some of the best ideas have come from developing other peoples’ ideas-

… where your first reaction is like, “No, that’s wrong,” and then just kind of sticking with it and going, “But how could we make it work?” And the most gratifying part when it succeeds is they get all the credit, and you’ve sort of elevated this person whose idea wouldn’t have been championed, whose idea by the insecure, egotistical lead of, you know, early 2000s would have just said no. Now their idea is the thing everybody in World of Warcraft or Overwatch is just loving, and they get all the credit.

I should give context to the listener who don’t know about the great Jeffrey Kaplan that you’re one of the most humble and always give credit to the team for everything and anything. And so everything we talk about today, I know you’re probably resisting constantly giving credit to the team on everything. So you’re the famous, “Hi, I’m Jeff from the Overwatch team,” right? So just as a small aside, thank you for your humility through your career, and thank you for always celebrating the team. But let’s talk about WoW. Let’s talk about World of Warcraft. Tell me what the early days of developing WoW was like. Maybe we should talk about what World of Warcraft, WoW is, going to Perplexity here.

Building World of Warcraft
Lex Fridman
World of Warcraft is a massively multiplayer online RPG where you create a character, level it up doing quests and dungeons, and progress your gear and power in an open fantasy world called Azeroth. At a basic level, you move, use abilities from your action bar, follow quests, and gradually learn a combat rotation that fits your class. And there’s all kinds of characters and roles and classes. You pick a race, appearance, starting zone, small racial bonuses. In a class, how you fight, what your role is in groups. Can you continue, fill in some of the gaps, what is World of Warcraft?

Jeff Kaplan
World of Warcraft, first of all, more than anything, is a world. Like, it’s a world that you can live in with real other people, and everybody’s kinda living out their fantasy. Chris Metzen, who was the creative director on World of Warcraft, and really, like, Allen Adham, who’s one of the founders of Blizzard, calls Chris “the heart and soul of Blizzard.” And it’s almost like when you’re making a Blizzard game, you’re making Chris’ imagination at some point. And Chris famously said, “The lead character of World of Warcraft is the world.” And I always believed that. So you’re trying to create this place that’s exciting and dangerous, but comfortable, but uncomfortable and gorgeous, and, you know it should feel massive, and it really is.

It’s, you know, can take a half an hour to get from one end of the world to the other. But it’s this world you’re living in. The world is divided into two warring factions. There’s the Horde and the Alliance, and that was a very important, very controversial decision that was made by Allen Adham, was the champion of the Horde and Alliance.

“… Alliance?” Like, “Okay, I don’t think we can be friends anymore.” But the Horde-Alliance decision was really controversial because in EverQuest, it was mixed race. They had all the races kind of like WoW did, but they could all group with each other. And Pardo and I came from EverQuest, where we felt like this was a horrible decision Allen was making. And we argued—Allen, Rob, Bob Fitch, and I would have lunch every single day, and we would just talk about WoW and the core design of WoW. Rob wasn’t even on WoW at that time. He was finishing Warcraft III. And we would fight over the Horde-Alliance split, if it was a good idea or not. And Allen had… He came from more of the Dark Age of Camelot community, which was another massively multiplayer online game that was more PvP based.

And he said the magic of that game was they had three factions, and he liked the fact that you were instantly on a team. You weren’t a loner in the world. And whether you liked it or not, you had people on your side. And Rob and I just argued and argued against it, and then sometime before beta, Allen retired. He went on to run a hedge fund, of all things. Like, got super into poker, got super into finance, left, and retires, like, I think it was nine months to a year before WoW shipped, which is kinda nuts. And Rob takes over as lead designer in Allen’s stead, and to Rob’s credit, the first thing he did was go… Speaking to what we were speaking about earlier, he said, “Allen’s a smart guy. The fact that he was fighting so hard for-“

“… Horde Alliance, we gotta do it.” And Rob and I sort of changed our point of view and got on board with Horde Alliance and went all in. And so, you know, the early days of WoW was… It was a great team. It was a mix of these veterans that we all looked up to. You know, we had Mark Kern running the team. Shane Dabiri was, you know, a legendary Blizzard developer. Bill Petras was the art director, and then we had Metzen, who was sort of like… Metzen was the cool big brother we all, you know, aspired to be.

I’m older than Metzen, but I looked up to him like a big brother. And then there were a lot of us who had never done it before, or they had also pulled a lot of people from other teams and other game types. Like, for example, the guys building the dungeons, they hired out of the Quake community. And because they didn’t have any hardcore MMO designer on the staff at that time, it was, you know, Kevin and Eric and Alan were sort of the only designers, they started building Quake dungeons- … as, like, Quake levels as the dungeons. At one point, WoW was even made in QeRadiant, which was the Quake engine. And then they later, you know, retooled to where they were using a proprietary engine. So we were like this hodgepodge, like the Bad News Bears-

Jeff Kaplan
Yeah. Like, okay, we’re gonna design World of Warcraft now. And I’ve said this later with hindsight, I think a huge part of WoW’s success, especially with the early WoW team, Team Two in its earliest formation, was that we didn’t know what we were doing. You kind of… Like, it’s that… Titan was the example for me. Titan was the attempt at making an MMO after World of Warcraft at Blizzard. And we failed horribly, and we had the best of the best on that team. And it’s because everybody was too much of an expert on how to make a groundbreaking phenomenon MMO. World of Warcraft was a bunch of people, like a very successful, sure-of-itself company who had made StarCraft, Diablo, Warcraft, with a bunch of yayhoos basically- … Who was like, “Yeah, we can compete with Sony Online.”

At the time, they were making EverQuest II. Like, if we go back in the time machine, EverQuest II had been announced. And EverQuest fans, we were just drooling for EverQuest II. It wasn’t, “Oh, cool, World of Warcraft.” It was EQ2 was gonna take, you know, the chalice and run with it. And then, of all things, they announced Star Wars Galaxies, and they had a brilliant designer on that, a guy named Raph Koster, who had come from Ultima Online, and he’s just a really smart game designer. If you ever watch one of his lectures, like, he lectured a lot at GDC, and, you know, we’re like, “Oh my God, they’re- they’re making EverQuest II and Star Wars Galaxies, and they have the Star Wars intellectual property.” “We’re fucked.”

So you’re feeling this immense pressure. You have this small team of just this hodgepodge of this unlikely team that kind of looks fast forwarding to Overwatch, the heroes in Overwatch, but working extremely hard. Now, you- you told me about crazy, crazy work hours, and not because you were forced to, but because you wanted to, because your heart was in it, because you’re like, “This is everything.” Like, you loved it.

Yeah. The games industry has a terrible reputation for insane amounts of overtime. It’s just called crunch. Like, do you crunch or not? These days, crunch is not allowed, not permitted, heavily frowned upon. If we were to work overtime, somebody’d write an article about it next week and say how horrible we are for working overtime. Back then, we worked insane, and I mean insane hours. The longest shift I ever worked straight was 30 hours. That’s when we were gold mastering Warcraft III. This was in my… I think War III shipped on July 3rd, 2002, so this would have been, like, late June, early July. Probably late June. And I had nothing to do with War III.

I should just say that. Like, in the credits, I’m additional help or additional testing or something like that. When I showed up in May of 2002, it was all-hands-on-deck World of Warcraft for E3. We got through E3, and then all hands on deck, the whole company, get War III out the door.

For shipping Warcraft III, and because I had not been involved with the game at all, and I was a brand new wet-behind-the-ears game designer, they’re like, “You’re just gonna help test whatever we tell you to test.” So we’re trying to gold master, and there’s a crash that happens rarely. If you run one of the cinematics, like you have to be watching the cinematic after one of the levels, and then there was a crash that happened. And so a programmer put in some logging to catch it, and then they needed somebody to just over and over again, “I need the crash to happen so I can fix the bug.” And I sat there for 30 hours and just watched the cinematic for 30 hours-

… straight. And it was the funniest thing, like it was almost surreal watching everybody leave at the… which was a trickle out. Like, everybody kind of trickles out, like, at- … different hours, you know? The family guys go much earlier than the single guys. And then watching everybody show up again in… the next morning, and they’re all, like, dressed different, and they look all refreshed. And I’m just like in the same position. You know, like eyes are beet red.

To the soundtrack of the cinematic and yeah.
To the soundtrack of the cinematic and yeah.
Jeff Kaplan
Yeah. But we crunched World of Warcraft, we crunched… The date slipped, so you do this thing. I remember Mark Kern standing the team up and saying, “We’re gonna crunch early so we don’t have to crunch later in the project.” And I really believe he wasn’t manipulating us. Like, I really genuinely believe that he believed in that. But with games, anything can happen, and they’re just… We slip uncontrollably all the time. And we slipped, and it sort of created just this death march, endless death march that… Like to this day, members of the WoW team will remember, like, Newport Rib. If I say that, they’ll have, like, twitches because, like, they would cater the dinner. They’d bring it in at, like, 6:00 or 7:00 at night.

And they’d… Everybody was eating Newport Rib or Panda Express. It was like the worst diet ever. I actually like Newport Rib, no shade- … on them. But you can only eat so much of it. And the carpets are stained and, like, dudes are falling asleep on the couches. And it was an unhealthy work environment. It gets pinned on… ‘Cause at a lot of places it is executive driven. And it is mandated from the top, but the hours that I worked, I never blamed on anyone but myself. I just wanted to. I remember, you know, coming in on Memorial Day, like, with sand from the beach on my feet because I really wanted to get some work done that day, and working through Christmas, and those were things I wanted to do. I never felt like somebody, you know, held my feet to the coals.

Lex Fridman
Yeah, it’s such a complicated thing because yeah, okay, you could say that’s unhealthy, but I know a large number of people, especially in their 20s, but actually throughout their career, that have been at companies that do crunch for a thing they believe in, for a thing they love, and it’s some of the most fulfilling years of their life, months and years of their life. And they also… it’s not just fulfilling, they grow from it, they learn from it, and it… You know, and when they… Especially when they talk back about it, about that time, they can see how incredible it was. Of course, when you’re going through it, sometimes it’s extremely difficult, you don’t know.

Lex Fridman
And then the crunch, like you mentioned, it’s supposed to be a month or two, and then it, it turns out to be a half a year, and then maybe it turns out to be something like a Titan type game where you never actually ship it, and it’s heartbreaking and the pain, it’s all… But then you look back and you realize how incredible that journey was.

Jeff Kaplan
I think, like, my reflections on it many years later, and having gone through, like, pretty crazy levels of crunch to more controlled, I think where crunch is problematic and people are good to be vocal about being opposed to it, is when it’s forced and unnecessary. There’s a lot of like, “Hey, if anybody on the team stays, we all stay”-

… kind of, which I think is not necessary. I don’t think executives who take off and work 40-hour weeks should be telling anybody to stay late. I think that’s wrong and immoral. But to me as an individual, as long as I’m not telling other people to do it, my life’s work is my passion and I want to do it as much as possible. I find myself, I don’t think I’ve ever worked less than 10 hours in a day. Like that… 10 hours is like a normal-ish day to me.

And I enjoy lots of weekends working because I enjoy it. It brings me pleasure and fulfillment. And all of that said, from a place of caution, especially in this era when people are very touchy about it. I don’t try to impose that on anybody else. I don’t want anybody to feel like they’re obligated to, but please understand it’s what makes me who I am, that work ethic. I enjoy it. I actually… Some of my fondest memories are from those WoW crunches.

And then looking back and reading some of these stories, it’s pretty cool because me, as a fan, on the receiving end of some of those video games, you bring joy to millions of people. It’s awesome. Let me ask you about quests, but first, quick bathroom break if it’s okay.

Quick 30-second thank you to our sponsors. Check them out in the description. It really is the best way to support this podcast. Go to lexfridman.com/sponsors. We got Fin for customer service AI agents, Blitzy for code generation in large code bases, BetterHelp for mental health, Shopify for selling stuff online, CodeRabbit for AI-powered code review, and Perplexity for curiosity-driven knowledge exploration. Choose wisely, my friends. And now, back to my conversation with Jeff Kaplan. Okay, we’re back. So I think it’s fair to say that before WoW, MMO leveling, like in EverQuest, consisted of, maybe that’s simplifying it a bit, but standing in one spot and killing monsters for hours.

How WoW changed video games
Lex Fridman
You helped develop with WoW, I would say a revolutionary idea of quest-driven leveling, where there’s a story driven, quest driven guide through the world, and it so happens that as part of doing that, you’re also leveling the character. So the leveling is both fun and is the engine that drives the story that then also immerses you into the world and pulls you in more and more and more and more. So take me through this process of developing that idea of quest driven design.

Sure. Yeah, there were actually a lot of people involved in it, and they all kind of contributed in their own unique ways. Alan Adham was the lead designer on WoW. When we first sort of decided we were gonna have a quest-based game, we used to joke that, like, EverQuest barely had any quests in it.

Jeff Kaplan
It did have quests, they just… They weren’t really in front of the player in an obvious way. You kind of had to seek them out on a website. And Alan knew that he wanted quests to be a big part of World of Warcraft. And so he hired me. That was my entry level position at Blizzard. And on the same day, he hired a guy named Pat Nagle, which was hilarious to me, because Pat was the… He had this funny title of HR and Facilities at Blizzard, because it was such a small company. So, like, if you sent an application in, Pat would deal with the application, or if the toilet overflowed, Pat would have to deal with it.

Jeff Kaplan
And so the whole time I was applying at Blizzard, I was going through Pat, and then on my first day, they put Pat and I in an office together, and he’s like, “Yeah, they hired me also as the quest designer.” And so Pat… And he was the most wonderful guy. We had so much fun. So Pat and I kind of designed the quest system. It was Alan’s idea to have it in the first place. And then there was that great designer I mentioned, Eric Dodds, who helped a lot with the interface of it all. And the idea was… At first, we actually on a whiteboard in Alan’s office, we estimated how many quests we thought EverQuest had to date.

Jeff Kaplan
And EverQuest had had, you know, I think four or three expansions at that point in time, and we’re like, “Wow, we have to make all of these quests like EverQuest has.” It’s gonna be a lot of quests, and it’s kind of up to me and Pat to do it all. And we believed all we had to do was match that EverQuest number. And Pat and I started working on, like, the design of the system and how it would interact, and Eric Dodds was really involved in how the interface… You know, like how you were going to interact with the NPCs and all of that. And we split up the world into like two zones. He was gonna take Elwynn Forest, which was the starting area for the humans, and I was gonna take Westfall, which was the sophomore zone after Elwynn for the humans.

Jeff Kaplan
Pat and I would meet with Chris Metzen, and those were the funnest meetings ever because Chris just has stories in his head and visions. Chris is, like, artist, storyteller, world builder extraordinaire, and he sort of described what he wanted going on in those zones. You know, you want the gameplay to follow the flow of what was going on with the stories of those areas. So we finished Elwynn and Westfall, and we did, like, a team play test. And our assumption was because the way EverQuest worked, players just wanted to level up. It was a level based game.

Jeff Kaplan
You go out. You kill a creature. You get experience points. You level up a little bit. And so the way people played EverQuest is they’d find these areas where there were lots of creatures, and you’d usually find the best experience efficiency cycle you could find, so, like, fast respawn kind of easy things to kill, and that’s how you would progress through EverQuest. And I remember Alan kind of telling us, like, “Hey, the quests… When Pat and Jeff write quests, they’ll aim us to where the creatures are.” You’ll do a quest, and then you’ll spend a few hours killing creatures in that area afterwards, and that’s how he imagined it would work. So we kind of set up the world that way. You know, Pat probably did a dozen, maybe 20 quests in Elwynn.

I’d do a dozen, 20 quests in Westfall, and we’d do this team play test. And we had a bunch of people on the team who never played MMOs, like guys with shooter background, you know, StarCraft fans, et cetera. And they’d play World of Warcraft. I think we played for, like, an hour or two, and we only did Elwynn Forest. And the overwhelming feedback from our team… And these are people who really didn’t play EverQuest, they’re like—My God, Pat, that was horrible. I ran out of quests, like, right away. And we’re like, wait a second. You expect to just have quests just keep going? And they’re like, yeah, we expect to have quests just keep going the whole way.

Jeff Kaplan
And we kinda had an oh shit moment right after that Elwynn Forest play test, where we realized, like, we had vastly underestimated the number of quests we were gonna need. And we changed, we developed this philosophy that’s kind of a shared philosophy across Blizzard games in general at this point. And I’ve heard it outside of Blizzard, other people in the industry, which is you design along the path of least resistance. So, basically what that means, like, in EverQuest, the path of least resistance if you wanted your character to hit max level is to find the easiest creatures and kill them over and over again in place, which to some people think is very boring. To me, I would do that for eight hours ’cause I think that’s fun.

Jeff Kaplan
But we decided in World of Warcraft, we said, why don’t we make the path of least resistance, so in this case, the way to get the best experience the fastest not to be killing creatures in one place, but will overload the experience into the quests themselves, and then that will move you through the world, which will get you to see everything. It will enable us to tell these awesome storylines. It sort of did a lot for the game, and I think it was like a fundamental change in the genre. Like, if you look at the things that… EverQuest was very popular and very successful, and it was hitting like hundreds of thousands of players. And WoW blew the doors open and was tens of millions of players.

Jeff Kaplan
And I think the fundamental difference there was that WoW allowed you to play as a single player. And what makes an MMO, massively multiplayer online game, massive is having the other people there. And they’re so important or else the world feels kind of wrong and dead. But the concept that we have to force you to interact with them to do anything is very off-putting to a lot of people. And the fact that people could come into WoW and just kind of the game design, the game design way of des- describing it is directed gameplay.

And some games have extremely tight directed gameplay. Like, for example, if you were to play a single player game like Last of Us, you know, you’ll have those moments where they’ll be like, you’ll come up to a log and then press triangle to duck or else, or whatever the duck button is-

… left stick to duck to go under. And that’s like the ultimate in directed gameplay. Like, they’re telling you exactly what to do. On the other end of the spectrum is a game like Minecraft, like vanilla Minecraft, where you’ll find it’s very divisive amongst gamers who love Minecraft or hate it. The ones who hate it are like, “I don’t know what I’m supposed to do.” Like, “You drop me in this world. I’m supposed to dig or something.” And that’s the type of player that needs directed gameplay or they’re gonna cycle out. Not all players need it. And what WoW did, that it doesn’t seem like an innovation, it doesn’t seem like revolutionary, but it sort of created this directed gameplay that felt optional, but really wasn’t.

Lex Fridman
I mean, I think it’s absolutely revolutionary. It basically changed gaming. It changed the way we see games. And it was so successful in part because it became a mechanism by which you could spend hundreds of hours, thousands of hours in the game. I mean, it’s kind of a, like, obviously… It’s one of those… All these great ideas are always like this, right? In retrospect, you’re like, “Well, obviously if you make the path of least resistance quest-driven gameplay, then it’s gonna be the reason that most people play.” But it is true that… I’m with you on… I both like the quests and Cow Level.

Lex Fridman
I guess you have to design for everybody. That’s the tricky thing. Like, how do you fine-tune this? If you think of it as a loop of like accept quest, kill 10 rats, turn in quest, ding, level up—that loop. Like, how do you fine-tune that so it’s maximum fun or fun for the maximum number of people? Is it… How- how difficult is that?

Jeff Kaplan
It’s extremely difficult. And not everybody’s good at doing that. We all, to some degree, lack the self-awareness of how we tick. So we’re all different types of gamers, but if you ask me to describe the type of gamer I am, I might actually be giving more of a picture of the type of gamer I wish I was or the type of gamer I want you to think I am versus the type of gamer I actually am.

By playing lots of games, you cannot be an exceptional game designer without playing the shit out of as much as you can and understanding on a deep level. And the weirdest part about it is you’re not just looking for the greatest hits. You learn just as much from a shitty game that you do from an amazing game. And also—like, a lousy game can have a great system that was tuned wrong, or lacked the correct interface, or they didn’t put the right visceral polish on it. There’s an executional aspect to all of it. When I’m playing, I’m not only, like, thinking about what makes this fun, I’m thinking about what makes this not fun. But I’m also watching everyone around me. My wife plays games, my kids play games.

And understanding, like, well, what do they do and how are they different to me? Why are they finding enjoyment in this? Why are they not? What’s frustrating? What did they miss?
Lex Fridman
And being raw honest with exactly what you’re saying. I mean, if I were to analyze the kind of gamer I am, why do I enjoy Cow Level? And why, above that, why do I enjoy loot? Why is loot so fun? Like, what is it about opening a chest and getting a bunch of stuff? I mean, that might be like at the core of what I enjoy about gaming. That, and walking around a beautiful world with nice music.

As a game designer, I am, at best, a quack psychologist. You know? We can motivate you to do some weird things. The two driving motivators are extrinsic and intrinsic. And all of us, at different times in our lives, in our gaming careers, whatever, we can shift from being intrinsically motivated to being extrinsically motivated. Obviously, loot is a big extrinsic motivation, but even saying that is too simplistic. Like, for example, on the loot boxes of Overwatch, there’s a masterfully designed system that was designed by a game designer, not by a businessperson or whatever. Like, not a commercial person. But beyond that, we also had a really good team who said the visceral opening of the box, the sound it makes-

… the graphics, like the way things spill out and animate, all of that is as satisfying as well. And you’re trying to… Like, there’s the lizard brain part of it. Of like, how does it… Like, I see chest. I know I’m gonna… It’s gonna feel good. It’s gonna feel good. And then there’s the spreadsheety part of it. Of, what does it have? Is it an upgrade? And I think great game designers know how to tap into both of those things.

Jeff Kaplan
You know, tap into the intrinsic and extrinsic. There’s… Like, when I was studying writing, you would study the elements of fiction. And, you know, these are just like basic things like plot and character development and setting and theme and whatever. And there’s no, like, textbook that exists for game design, at least none that has been introduced to me yet. But I think about, like, elements of fun.

Jeff Kaplan
What are the things that create fun for players? And they’re not the same. Like, it really… Every human being is different. Like, progression is fun. Sense of progression that I’m investing. I’m putting an investment into this game, and then the game is recognizing my investment. That things like leveling, things like the amount of gold you have, those are all investment based. There’s mastery. There’s just pure raw skill. Creativity is one. And hand-in-hand with creativity is customization. And some of those can be aesthetic. Like, look at my customized character, and I have the black curly hair, and I put an earring in my character and I’m customizing in that way. The other is customizing my build.

I’m gonna come up with a whirlwind barbarian and I’m the first to do it. These are all elements of fun that designers can tap into, and in fact are frequently tapping into. But they’re never defined anywhere, and I find that players drift. Like, I’m the type of player who’s not really loot motivated. I’m more motivated by seeing the content the world has to offer. And often that takes me on a detour of being loot motivated, because there might be a dragon or a demon somewhere that I can’t beat without this level of armor and sword. So now I’m loot motivated for some period of time, to get back to being content motivated.

Or if I’m having trouble defeating a boss, I might have to go back and look at the skills and abilities that my character’s using, and I have to go into creativity mode. “Oh, he has that one AE where he…” Area of effect. “…where he puts a curse on me.” And, you know, “If I had this counterability to the curse, I could beat the boss to get the loot, to get to the next boss.” These are all cycles that are tapping into all those different elements of fun.

And ultimately enjoying and discovering what the world gives you. Has to offer to you. And you’re… You have a lot of hats as a gamer, so you love the RPG/MMORPG world, but you’re also a big shooter guy. Can you explain to me what fun in a shooter context is? And we’ll talk about Overwatch as a specific kind of fun. Maybe… But you’re also a huge fan of the ultra-realistic shooters. Call of Duty. What is the definition of fun there?

Okay.
Okay.

There’s an intimacy also to the first person camera. And now, not all shooters are first person. There is a large trend these days to third person. I really think PUBG and Fortnite sort of opened that third person shooter door. And you’re seeing games like ARC Raiders are third person. But to me, nothing is as pure as first person. Like you’re- … literally living in the world as that being. You can look at your hands, and it’s that pure visceral test of skill of, “Can you click on the thing fast enough?” And when it’s PvP based, you know that’s coming at you.

Jeff Kaplan
So PvP is player versus player. So that means a combative, you know… If Lex and I are up against each other, we’re attacking each other. We call that PvP. You can get killed by another player. Player versus environment is anytime you’re shooting computer-controlled opponents. So if it’s a game about dragons, the dragon is the E, the environment in PvE.

And we should say that PvP and PvE, the P might be multiple players. It could be five versus five, six versus six for PvP. And for PvE, it could be, like, raids where it’s multiple people, large groups of people going against the AI.

Jeff Kaplan
Yep. So single player, that’s a game that you play totally by yourself. Like, you don’t play with anybody else. You can’t play with anybody else. It’s not networked to play with other people. For example, I’m playing a game called Story of Seasons right now on the Switch, which I just play by myself. I have my farm. You know, there’s a town. I’m meeting people in the town, and no one can come and join me and interact with that. So it’s a very controlled experience. Single player games are very difficult, or they can be very difficult and expensive in terms of production to create. Like, if you think of a game, like Uncharted or Last of Us that’s made by Naughty Dog, like, those are kind of the preeminent best single player games you could talk about.

They’re very handcrafted. Every experience is made just for you. One up from that is what I call co-op. And these terms become interchangeable, so I’m using some semantics here. But co-op is any cooperative experience that we can play together, but we’re sharing an exact same experience very intentionally. And it’s me sharing that experience only with other people that I know. So a great example of a cooperative game, maybe one of the best of all time, was Left 4 Dead, which is a game where you and three other people go in and you fight, like, hordes of zombies, and you try to progress through to the end safe room. It’s a very cooperative experience. A game like Diablo IV, you can play cooperatively with other people.

Now, one up from that is multiplayer, and that’s when you’re engaging with strangers who are in the same world that you might not have the same cooperative goals as. You might have very opposed goals to them. You might PvP them, or they might just be random strangers that you pass in a town or city and never see again. And then massively multiplayer, which is what the MMO online sort of stands for, massively multiplayer online game, that’s when you’re breaking into thousands of players. And the worlds become really, really big at that point.

By the way, we should say that the co-op could be remote connection, but there’s also, what would you call it, couch co-op where you have two people. Some games are really designed well for the experience of two humans sitting together and playing the game together. Which is a really tricky thing to design for, but if it’s done well, it’s a… It’s a really fulfilling experience. Like, with a friend, with a loved one, you can, like, play a game together. And Diablo IV, I should say, is an example of a game that does that really well. They do couch co-op. Like, two people can play Diablo sitting together and there’s a real intimate experience in that.

Yeah, couch co-op—it’s funny, ’cause it actually, like, predates the couch even. Some of those old arcade games- … like, would have two joysticks on them and then you could play- … with somebody else. Or there’s, you know, the famous game Gauntlet—

We would sit and we’d play NHL 93- … on the couch. And anybody who lost, you’d lose the controller. And you could play that with up to four people playing, or we… I remember one of the big games that came out was Mortal Kombat. And we would play Mortal Kombat on the Sega Genesis, and it was the house rules were, you know, whoever lost, so whether you were in your college dorm or just some buddy’s apartment and there’s five people there, you’re constantly cycling everybody in and out.

… with other people. That’s why I’ve always… I’ve never made a single-player game. Uh, I have great admiration for them. I don’t know if I could do it. The challenge… The reason I love multiplayer so much, the way I describe being a game director or game designer on a multiplayer game, it’s like imagine if you were gonna be a movie director, and you were gonna have all these actors and set designers and props and, you know, writers and scripts and all of this stuff, and your goal was to get a certain movie made. But we’re gonna ask you, the director, to just… You’re gonna leave the room. You can set it all up ahead of time, and then you’re not allowed to be there or talk to anybody involved in it.

From a designer/creator perspective, ’cause you don’t know what the players will create, so that’s fun to see. You, you, you lay out the chessboard, you lay out the world, and then you get to watch what they create together. That’s true.

I struggle because sometimes people call me the anti-story guy in games, and that really hurts me because, like, I actually love story in games, and I counter that I’m the anti-shitty story guy. And what I mean by that is like, A, the most magical stories that I’ve ever heard come out of video games are player stories about, you know, the time I gave Barfa a potion and then I met him in real life. Like, that’s better than any video game writing that I’ve heard in a long while. The player story is so much more interesting. You know? “Lex, why do you like the cow level so much?” “Tell me about some goofy time-” “… like a loot goblin drew you into the most danger.”

“And… But there was another player there, and then…” You know, like, those are the stories that I think are more interesting from games. There are some exceptional writers in video games and some exceptional games at story. You know, I’ve mentioned Naughty Dog, like they’re kind of on another level. But Valve has amazing writing. The writing behind Half-Life 2, Marc Laidlaw; the writing behind Portal- … and Portal 2. I think it was Erik Wolpaw, who is hilarious, just amazing, and Rockstar.

Red Dead Redemption 2 is one of my favorite games of all time, and that’s a game where you can see the expertise and mastery of the game design and the narrative design, and the fact that you can have those player stories of just the goofy shit. Like, I remember… ‘Cause the controls are a little awkward in Red Dead for a PC player who’s playing on console. Like, I always get confused about, like, taking out my gun and putting it away, and what’s, you know, the L1 and L2.

Like, as a PC gamer, I’m just like, “Let me bind this stuff to where I want it.” And so like, you know, a guy in town rides by and he’s like, “Howdy, partner.” And I go to, like, give him the Arthur Morgan, you know, “Hey, what’s up?” back, and I just whip out my sawed-off shotgun and, like, blow his fucking head off. And then the whole town is like… Suddenly I’m, like, under… I’m wanted and I’m being chased, and then there’s a train that, like, takes out the posse, and-

And that’s the combination. And then Rockstar does a really good job with, you know, even in Grand Theft Auto with the radio.

There was a moment in Red Dead where it… There’s the Daniel Lanois song— …”That’s the Way It Is”. I just… I love Daniel Lanois, so the fact that somehow Rockstar landed him and like, was able to get that song out of him. And there’s this moment where you’re, like, riding back and they start that song, and- Everything up to then had been gorgeous, like, more of a score. There’s Woody Jackson, who’s, like, a really amazing game composer. He had done the score for that, and so nothing had been, like, lyrical with words. And then they play the Daniel Lanois song, and there’s, like, the quotes are coming back—

Yeah, there’s certain games where, you know… I mean, that moment, you just imagine the number of people who shed a tear during that moment, and that’s just a reflection of how much you’re invested into this world, into these characters, and it’s a beautiful thing. I have to ask you about this, this image that you sent me. It’s super cool, so I’d love it if we could nerd out about it a little bit, the zone flow for the original World of Warcraft. There’s a bunch of zones. It’d be awesome if you kinda talk through how, like, this world is built. Take me to that time when you were designing this, before anyone else got a chance to play it.

All WoW stuff. It would start from that inspiration of Chris and the world. And, you know, it was so fun hanging out with Chris because we had whiteboards all over the place, and, you know, “Hey, Chris, we should make Eastern Kingdoms. What do you think it should be?” And he would just tell you the story of each of these as he’s just drawing. And Chris is a really talented artist, so the map would be gorgeous. I have lots of, like, photographs of Chris maps that he would just kind of whiteboard up. He’s like, you know, “Here’s the Dwarven Lands, there’s Wetlands with Khaz Modan up there, and that’s where this, you know, tribe of dwarves were from.” And then they, you know, humans are going to be down with Elwynn Forest.

And then Westfall, there’s, you know, this group called the Defias Brotherhood and they have a place called Deadmines.” So I would talk to Chris because you want to capture the spirit, like, as a game designer, you want to capture the experience that’s in people’s heads. So, like, take Burning Steppes, for example. Supposed to be one of the scariest places with lava and dragons and, you know, all this kind of stuff. That doesn’t feel like where you want to start. It feels like where you want to end, so you kind of work the world flow in a way that puts that at the end. But there was also kind of some magic to the original starting areas, where we gave the dwarves and the humans a free flight path between… The dwarf hometown was called Ironforge, the human hometown was called Stormwind.

So, like, take Burning Steppes, for example. Supposed to be one of the scariest places with lava and dragons and, you know, all this kind of stuff. That doesn’t feel like where you want to start. It feels like where you want to end, so you kind of work the world flow in a way that puts that at the end. But there was also kind of some magic to the original starting areas, where we gave the dwarves and the humans a free flight path between… The dwarf hometown was called Ironforge, the human hometown was called Stormwind.

And we allowed you to fly for free. So, like, these little newbies who were, you know, level five or something, if you played a dwarf and I played a human, I’m like, “Oh, Lex, don’t worry, I’ll come. You know, I’ll come to Ironforge and we’ll hook up and I’ll just fly out to you,” which is the magic of World of Warcraft. You have to fly over Burning Steppes and Searing Gorge, and you look down and you’re like, “Holy shit, that looks scary and dangerous.” And it plants that seed of things to come.

So you’ve designed some incredible quests. Is there any that stand out that you’re proud of or ashamed of? I mean, you famously have designed the Green Hills of Stranglethorn quest. One of the most infamous quests in the history of WoW, of gaming, where you had to collect a bunch of pages, or… Green Hills of Stranglethorn, maybe, can you comment on that one or any quest that just springs to mind?

Jeff Kaplan
Green Hills of Stranglethorn holds a lot of emotional value for me because amongst WoW players back in the day, it was unanimously hated as one of the shittiest, most annoying quests. But it holds a really special place in my heart. First of all, it’s one of the few times that I just, like, wrote a short story that’s actually in the game. It’s me paying homage to Hemingway, and the guy who gives you the quest, his name is Hemet Nesingwary, which is just me rearranging the letters of Hemingway. There’s another quest giver there that’s Kerouac’s name also mixed up. And then it was the typical hubris of a junior game designer who thinks he’s clever but is actually a dipshit. That’s- That’s the Green Hills of Stranglethorn, like, summed up.

So, like, I wrote the story over, like, it was, I think, winter break, like, everybody was gone and I just was so happy to be in the office, you know, I’m at Blizzard by myself writing late at night. And the whole idea, and this is, this is very much what I call ant farm designer, which is bad. Which is, you know, you’re the game designer who’s playing God, and players are the ants in your ant farm, and you want to see what they’re gonna do, which is not the correct way to be a good multiplayer designer. But I hadn’t learned that yet, and there’s a really great famous Sid Meier quote where he says there’s three types of fun. Fun for the player, fun for the designer, and fun for the computer.

And we catch ourselves, we’re like, you know, we gotta be really care… It has to be fun for the player, not fun for us. So this Green Hills of Stranglethorn quest was like an ant farm design of, I’m gonna write this, honestly, probably pretty shitty story, I haven’t read it since 2003 so God only knows if it’s any good. But I wrote the story and then I divided it up into all of these different pages. And the quest giver, Hemet Nesingwary, wants you to put together, like, the story’s like, he wrote this book, but then the pages got scattered across Stranglethorn Vale. And some… When you’re doing quest design, you’re really thinking about the player flow and you’re directing them from quest giver hubs out until these destinations, and you want them to do all the destinations.

But sometimes we would do these bridging quests where you could do anything in the zone and it sort of had this overlap. And so the pages of Green Hills of Stranglethorn could be looted off of any creature anywhere in Stranglethorn Vale, and it was kind of like that McDonald’s Monopoly game where you have to have all the pieces or else you’re not gonna win. But where I really went south, I don’t think the idea in a vacuum is horrible, but where this really fell apart was the interface of World of Warcraft wasn’t set up. Like the pages didn’t stack, there wasn’t a dedicated container to put all the pages in, so players had very limited bag space. And as they’re fighting in Stranglethorn Vale, I’m just shitting up their inventory with all of these pages and they only needed so many.

Like you might get unlucky and you have like three page fives that are just junk in your inventory, and I might have like eight page sixes. And then everybody… And this was the goal, like the, the designer trying to puppeteer everybody. Everybody in Stranglethorn chat is like, “Hey, I’m looking for a page six. Anyone got a page three?” And that was like my fantasy as a designer of like, and then they’re gonna be social and meet each other, and players are gonna be appreciative for each other, but really all everybody did was just no… Eventually, no one did the quest. They just were super annoyed, or they went to the Auction House. So the quest is famous in that it was so aggravating and annoying and it just became a way…

Jeff Kaplan
It not only became a way for me to learn from my mistakes, but because I was very open with the fact that I didn’t think it was good and that the quest had failed, it opened the door for us at Blizzard to be critical of our own work. Like it’s always easier if you’re the first one to go out and say, “Hey, guys, I think I made one of the shittiest quests in the game and here’s why.” And then it sort of challenged people to make better versions of it.

How Blizzard made great video games
Lex Fridman
I mean, again, you continue to speak with so much humility. But WoW turned out to be one of the biggest games of all time both in terms of popularity, how many players play it, revenue, and critical acclaim. And then you rose to become a game director of WoW helping release Wrath of the Lich King, which by many is considered to be the greatest expansion. I mean, there’s a million questions I can ask here, but maybe this is also a good place to ask about the famous Blizzard polish. So Blizzard as a company has historically, and you were certainly a big part of that, delivered these games.

They were just, got so many pieces right and well-functioning and well-coordinated, and just feel finished in a way that a lot of other games don’t get right. So what does it take to take this gigantic game, this game played by millions of people, loved by millions of people, and deliver it in a way where it’s like it all just works?

To have a level of polish is like a studio wide culture that has to be instilled in everybody, like no one can be satisfied with a bug. Every game is gonna have bugs, and Blizzard games have bugs. It’s a question of, how quickly do you fix them and with what urgency? And as players ourselves, if we’re playing as much as anybody else, we’re gonna be motivated to fix the bugs. There are some really tactical aspects to it, too. The quality assurance department at Blizzard is the best in the industry. Like the people who come and do QA at Blizzard, they are passionate gamers. Many of them want to be developers themselves, and they’re not just doing it for a job. They do it because they fucking love the game.

And the relationship we tried to develop between us on the development teams and QA was extremely tight. And whenever possible, we also tried to sit as many QA members up with the development team as possible, depending on the logistics of… You know, in the early days, we didn’t always have the space for all of QA to sit with us. We were very fortunate on the Overwatch team to have a large amount of QA sitting with us, and then developing that relationship. You know, in the early days there, there were these fears of like, “Well, QA can’t talk to the developers,” and trying to shatter that-

… of, because some of our QA members knew the game so inside out, you would just say to ’em like, “Hey, dude. Just message me anytime. Here’s my home number. Like, call me if there’s a bug. If you think we’re gonna get raked over the coals on this, you gotta speak up. I don’t care what the chain of command is. Like, we gotta fix this thing.” So QA was amazing.

I mean, so can you speak to QA, quality assurance? At the peak of the craft, what does it entail? Like you’re basically experiencing the game and trying to figure out particular slices of that experience that could be improved?

Yeah. People simplify the role by just, “Oh, these guys just get to play games all day and then, like, let us know if there’s a bug.” They are so systematic in the way they test stuff. They come up with these plans that are actually amazing of, like, who’s gonna test what. There’s a lot of regression testing that goes on. Within QA there will also be compatibility testing. The Blizzard compatibility department was amazing. Like, they had every card, every machine, every configuration, and they would roll through to make sure there wasn’t some quirk that was gonna come up on some video card or some motherboard that you weren’t expecting. But it was all very systematic. It wasn’t just Wild West, let’s play the game.

And then as a developer interacting with QA, you would find that there were certain specialists whether like, like for example, on Overwatch, there were a couple of players that… Like, we all were shooter players when we were making Overwatch, but I’m not like esports level shooter player. I’m like, you know, Gen Xer, “Remember Doom, how good I was”- … type of shooter player. But we had, you know, a couple of these QA specialists who, like, they could just snipe from 100 meters out and hit the shot every time and tell us if there was a frame of input delay, you know? And then you sit that person with an engineer and say, “Hey, I think there’s some input lag here.”

And sure enough, they’d be right. But you have to have that relationship where the devs trust QA. Or just even on, like World of Warcraft, they had a great relationship with QA in that they built out a full raid team to do the raids. And then you’re not only, like, looking for bugs, like, “Hey, the dragon was supposed to fly and instead it just, like, sunk through the world and the game crashed,” which would happen. But, like, if you really value QA, you’re asking them, “What do you… Dude, what do you think? You’re…” You know? Like, “10 million people are gonna see this. Your opinion, multiply it, you know? It matters. What do you think? You know? Are you having fun? Oh, yeah, this is cool. This isn’t cool.” So QA was important.

The other thing that was important is the Blizzard engineering, which you have to architect your game to be hotfixable.

Jeff Kaplan
And what a hotfix is, games, there’s a couple ways to fix ’em. The way most of us know, ’cause all the software we have gets a patch, you know? You have to update it. You have to download a new version of it. Windows, you know, you get that annoying message, like, “There’s a new version of Windows.” And it takes, you know, a few minutes and you update it. You know, obviously, we patch our games and that’s where we fix a lot of bugs, but if you really wanna run a game like Overwatch or World of Warcraft successfully, you need master level engineers who have architected the client and server in such a way that you can hotfix the game on a dime. And what a hotfix is, is a server patch that no one’s client has to go down for.

Mm-hmm. That’s because you’re dealing with a huge number of players and you discover an issue and you want to respond to that issue really quickly.
Mm-hmm. That’s because you’re dealing with a huge number of players and you discover an issue and you want to respond to that issue really quickly.
Jeff Kaplan
Yeah. There’s emergency issues like something’s crashing. Like, the worst case scenario is anytime the server’s crashing. Or in Overwatch, like, a really catastrophic bug would be something where you have to disable a hero. Like, someone found an exploit and you have to disable a hero from the lineup. You want to turn around that hotfix if you can in a half an hour, get that hero back live. You might have somebody who only plays that hero, and the only reason they’re gonna play Overwatch is because that hero’s active. You don’t want to wait for patches and you want to hotfix- … as fast as you can.

Yeah. Players feel it. Like, they… That’s where there’s this idea of, like, the love and the craftsmanship of the developer that you can feel. Like, any product, you know your iPhone or Android or, like, any computer or consumer product, you can feel when there are people who loved it behind it and aren’t just putting it out on a shelf. And games have that as well, where you can feel the heart and soul of the developer in the thing. And some of that’s, like, the joy and delight of, like, that there’s a Cow Level, right? That that’s… You know, you can feel the humanity of the development team-

… through that. But another part of that is, like, do they clean up their fucking yard, you know? Does this game work? Is it… And it’s not just the bugs and the crashes. It’s, like, when balance gets wacky and stupid and, you know, suddenly everybody’s a Barbarian and whirlwinding and no one else will play anything else. You’re like, “We should probably fix that,” you know?

You know, that’s what I was making. And very shortly after WoW shipped, you know, Allen left as lead before the beta, or like right around the beta, and then Rob took over as the lead designer, and then he left the team very shortly after WoW shipped to go start StarCraft II. And he put myself and Tom Chilton in charge. Tom is a designer who… He was a great partner of mine and a great leader and he actually came from Ultima Online. And so I always looked up to Tom because he had a lot more experience than I did. And this is like early 2005, the world was on fire, the servers were barely running… WoW was just, had taken off like gangbusters, and they basically put me and Tom in charge of WoW.

I didn’t even have a lead title, my title was Senior Game Designer. And Tom and I were running the design of WoW at that time. So I thought it was totally normal, and I thought what we were experiencing with WoW was just normal for making a video game because it was the first video game that I had worked on. I thought it was the funnest joyride because we were working on WoW, we were still working insane hours and then I’d get home, eat dinner, and then me and my wife would log in and play WoW, you know, for four hours, and then I’d go in the next day and I’d work… And it was just this… My whole life was World of Warcraft. And I loved it.

Like I loved everything from, you know, the creative meetings with Chris Metzen and just what an inspiration and muse he was, down to the simplest, dumbest design stuff that like we as game designers, like, you wanna talk about why a button is in the lower-left versus lower-right and what does that mean? That’s like two hours of discussion. And is there a better way? Like the 10,000 minutiae problems were thrilling to me. And then also the big disasters. Like the big… I had in the early days of WoW, we didn’t really have all the processes in place for, like, how to deal with being a successful online game, and I literally had GMs, like game masters, these are customer support guys, calling my home phone at 3:00 in the morning.

Like the big… I had in the early days of WoW, we didn’t really have all the processes in place for, like, how to deal with being a successful online game, and I literally had GMs, like game masters, these are customer support guys, calling my home phone at 3:00 in the morning.
Jeff Kaplan
Like, I remember this one time there was some faction token in Stranglethorn Vale and they figured out a way to exploit it, and this GM calls me panicked, it’s 3:00 in the morning. He’s like, “I’m just spawning…” Uh, what, what did we call ’em? Guardians of Blizzard. They were these giant infernals that we just made that instantly death touched anything. We used to have them when we were in the beta, like off in the distance of places players weren’t supposed to get in case they cheated their way there. And this GM is just spawning them all over Stranglethorn Vale because he’s worried because the players are exploiting. Yeah. It’s like 3:00 in the morning and I’m talking in hushed tones because my wife is sleeping right next to the bed.

I’m doing this ’cause it was actually like before the cell phone days when I actually had a landline. But that’s just how… And I loved it. I loved the thrill of those big moments, the minutiae. And I felt like through the running WoW Live, which was me and Tom together with an amazing team, we kind of learned how to be the WoW team. And putting WoW in a box and shipping it was like only chapter one in a 12-chapter book essentially. And that first how to run the game, how to patch it, what type of content, how to deal with emergencies, what should our customer support be like. I mean, we would debate should we have a launcher or not. You know, in the early days, the only reason the launcher existed in WoW was to run anti-cheat on your machine.

And we had a moment where we figured out how to put that into the game and out of the launcher. And it was the first time I ever really had an in-depth conversation with Mike Morhaime. He’s like, “You gotta bring the launcher back, guys.” We’re like, “Why?” He’s like, “There’s no better way for us to talk to our players.” Um, and I remember trying to hide the launcher. And to this day, Mike was right. Like, that launcher turned out to be the best thing we ever had. That’s essentially what Battle.net has morphed into these days. But all those decisions and when it came time to make Burning Crusade, you know, at that point, Tom and I were leads. We were full, they had actually promoted us.

There was, there were two big exoduses of groups that quit Blizzard; they were disenfranchised if you can believe it. Like we just shipped World of Warcraft and this whole group just walked out the door. I was actually sitting, my desk faced Morhaime’s office, and I watched them all go in and quit, and they were the group that formed Carbine… which made the game WildStar. Ended up taking them 10 years to make, and they were just really unhappy with World of Warcraft, and they were unhappy with… I don’t know what they were unhappy with. They were unhappy enough to walk out the door right after we had shipped WoW.

That’s incredible. Like, what, what is it? Just because they put their heart and soul into the game and they maybe get exhausted in a certain kind of way?

Yeah, and I don’t want to… It’s not fair of me to speak on their behalf. I think they were promised some compensation that they didn’t immediately see. I don’t know if the game… Like, here’s the weird part when you make a game. When you come up with the idea and you start pitching it to people, that’s the best the game is ever gonna be, and then you work on it. Like, you know, games I worked on take five years, you know? Overwatch was two and a half, three years. Every day you get close to ship, the imagination of the ideal game gets farther and farther from the reality, and you’re always shipping this, like, greatly sacrificed thing that nowhere near matches the imagination- … of the inception of the idea, so you become disenfranchised with the concept.

Lex Fridman
So in some sense, you’re shipping… You’re constantly in a state of disappointment. You’re basically shipping a lesser thing than you’ve been dreaming about.

Yes.
Yes.
Lex Fridman
You’re doing less and less and less, saying no and no, and cutting, and all that kind of stuff. Yeah, it’s difficult, psychologically difficult, but nevertheless, the result when you zoom out, it’s one of the greatest games of all time that millions of people played for thousands of hours. It’s just… Did you ever have an experience, a realization how huge WoW was in terms of not, like, statistics on the server and so on, but the cultural impact it had?

The first time was the first BlizzCon, which was in 2005. So when WoW shipped—and this is so weird to tell people—but on the team, not everyone, but a lot of us were very demoralized after WoW shipped. There were all sorts of issues with the servers because the game did way more successful than we expected it to do and the server load was just nuts. Like, we were just… We were doing our best to hire database programmers, you know, ’cause we just didn’t know how to deal with the sheer scope of the game. But when you’re an individual like… And at that time, like I mentioned, there were multiple exoduses of people who quit Blizzard. They went and formed a couple notable studios. One was Carbine, the other was Red 5.

Jeff Kaplan
And we lost, like, kind of our core people. Like, when Red 5 started, that was our team leader, that was Mark Kern, and our art director, Bill Petris, they quit. When Carbine started, it was, I think, all of our animators and some of our best programmers and… Like, it’s really demoralizing when you lose team members like that, but then we were also underwater. Like, the servers aren’t running, we’re not able to keep up with demand, and we had to start putting patches out, and now we’re making patches like… For a while we had one animator who stuck around, and then eventually he left also, but you’re doing like, okay, we gotta now do a patch without an animator.

A lot of our art team was gone at that point, and you’re trying to keep the ship afloat and the morale was just in the shitter. Like, everybody felt very down on Team Two, the WoW team was called Team Two, and that we had somehow failed. And during that time, there was this idea to do BlizzCon, and the way that started was EverQuest had done these, like, meetups because they knew it was, like, a big guild social game, and people would get together at like some hotel ballroom and you’d sit with your guild at like a banquet room table.

And to give credit where credit’s due, I remember sitting in the meeting for what was to become BlizzCon, it was Pardo who said, “Blizzard’s bigger than that. We’re not just one game, and I know everybody’s focused on World of Warcraft right now, we should do BlizzCon.” And at the time, we had a game called StarCraft: Ghost was in development, and that was getting ready to show, and there was Frozen Throne, which was the expansion to Warcraft III, but, like, we knew we were gonna make StarCraft II. And then there was a lot of motion happening with Blizzard North, which is a whole separate story, but there was like, hey, we could really do a cool show-

… that’s this BlizzCon thing. And at first, we kind of announced it and it just was crickets. You know when you’re, like, excited about something, you’re like, “Man, everybody’s gonna love. Like, we’re doing BlizzCon,” and everybody’s kinda like, “Crickets. What’s BlizzCon? Who cares?” And we’re, we’re idiots, we’re reading the forums, and the forums are just flaming us all the time, like, “There’s lag on this server and can’t log into that server.” And that was our perspective of what was happening. And then, like I said, give Mike Morhaime credit where credit’s due. He kept us committed to that launcher, and they put the BlizzCon tickets on the launcher, which they hadn’t done before. It was on the website.

And so everybody who logged into World of Warcraft suddenly got this like, “Hey, we’re doing BlizzCon in Anaheim, do you wanna come?” Sold out instant. Like, instantly sold out. And when I showed up at that show, it… One of the most emotional things in my life. It was nothing but an outpouring of love. And up until that point, your perception was, because you’re just reading online and it was… The perception is such hatred, because people who are passionate online, they express themselves in the harshest ways ’cause it gets attention. You know, that’s the lesson I should’ve learned from my early days. And it’s such an unfortunate thing, because then you met these people in person and they loved World of Warcraft.

Maybe that’s just the way it is. But in person, all of the people that are passionate about a particular topic, and whatever that topic is, it could be games, it could be at conferences, technical conferences, they are all mostly full of love. And just the way they talk about stuff, they nerd out. Even the disagreements are drenched in this respect and appreciation and love for the game, for the topic.

If you say, “I love this thing. Here’s an apple. I love apples,” or, “I love bananas. I love fruit…” Like, “I love X,” whatever. You just get made fun of. You get… And then so what the lesson you learn from that is, “Well, I’m just not going to speak up when I love something. I’m going to instead speak up when I, maybe how much I hate another thing that’s similar to it.” Or maybe join in when we’re making fun of a particular quirky thing, about, “Don’t you hate it when bananas are too ripe or too…” Versus like not saying the, calling out the elephant in the room is, “We’re all gathered here today ’cause we love the thing.”

It’s interesting. It’s that aspect of the internet that I think is jarring to a lot of people depending on the game, but if you go to Discord or Reddit or so on, in the communities that love a particular video game, there’s a… If you’re not used to it, and I don’t often go, so when I go it’s like, “Wow, there’s a lot of, like, pretty intense kinda mockery and derision and so on.” But you get used to it pretty quick and you understand it. I just, I wish there was more love.

I feel bad because I played a role in the earliest development of some of that online culture. It really was social media before it was called social media. You know, I ran a… I actually had this reputation for being edgier than I really was. There were a couple notable posts that survived 30 years that people like to look back on but they don’t look back on the ones where I’m just being chill. And that’s unfortunate. I think a lot as a game designer about the design of social media. And unfortunately, social media in general is designed in such a way where the maximum hyperbole works, and that’s how you get the most points is by being max hyperbolic.

And usually, unfortunately, it’s more in the negative direction than the positive direction. You know, if I say, “That’s, that’s a pretty nice mug. I’ve seen nicer, but I like this one,” no one’s interested in that. I have to either love this thing, or better, this thing’s a crime against humanity- … in some way.

Especially when you’re young. I got to see this kinda interesting thing. So I was at I spent, that’s what we’re talking about, you’re from Pasadena, so I’ve been spending a lot of time in Caltech and working on robots, and we get to see students come in from high school. Undergraduates come in and, like a tour, hang out with the robots. And middle school also. And the interesting thing you see, the younger that they are, the more prevalent this effect, which is all of them are kind of afraid to show that they think a thing is awesome. They’re all… You could just feel they’re checking, “Is it okay?”

So they’re kinda like the default mode is whatever, this, everything is stupid, this is stupid. You know, ’cause that’s the safe place to be. It’s a real act of vulnerability. I would say it’s an act of courage, especially for a young person, to be like, “Holy shit, that’s awesome.” Like, I’m gonna, if I think this is awesome, I’m gonna be the nerd, I’m gonna take the risk and be made fun of for saying, “I love this,” in that case, it’s, “I love this robot.” So that’s an actual psychological effect that also young people are dealing with, in-person also. So I think, I just wanna say, for young people listening to this, be vulnerable, be courageous and say you love a thing if you love a thing. And do more of that on the internet, I think.

I couldn’t agree more. You know, as somebody who’s taken a lot of heat online, like any game developer, you just get destroyed. Doing what you do, you must get destroyed, you know? And it doesn’t matter, you get 100 compliments, it’s the one, you know, you’re… And you’re supposed to read it and supposed to be fine with it and have it not affect you. It’ll stay with you for years, you know? I have those. And I think of it, like the cheesy, the cheesy way I think about it is like, is there some kind of social Darwinism going on? And my big worry is that there are creators… Like, now being a creator of anything, writer, musician, you know, make online videos, whatever creator means to you, make games.

Now part of the skillset is being able to weather like a fire hose of criticism like the world has never seen. And I make up these scenarios in my head of like, would Van Gogh have existed if, you know, Reddit and all these things were out there commenting on… Like, how many people were able to communicate with Beethoven in his lifetime, or in a week? Like, how many influences could comment on his music directly to him? Versus like if I want to insult Brad Pitt right now, I can just go on 10 different devices and do it. And it’s like that level of access is very dangerous, and I worry that there is a whole group of people who’s receding from us that will never see the brilliance, and they’re being shut out by the negativity.

There- there’s a very real example, was Jay Wilson, who I think is one of the great design minds, who was the game director of Diablo III. And he took so much heat, it just affected him to the point where he essentially retired from making games. Went and, you know, wrote novels. I was very happy for him because, you know, I’m glad he found his place, and I think he’s getting back into making games now. But we lost, we essentially… Like, think how many people loved Diablo III and played the shit out of Diablo III. And Jay is one of the people you have to thank for that. And yet that community basically removed him from making games for like 10, 15 years, and it feels criminal to me.

Yeah, absolutely. They… So this is a call to action, again. People out there, support, support, especially young creators, support them. They need it. Like you think negativity has no cost, but it does. You’re robbing the world of some of the great creations. And also, allow creators to suck and to improve. Because that’s what the process of creation is like, is to take risks. To take risks meaning being vulnerable, being cringe.
Yeah, absolutely. They… So this is a call to action, again. People out there, support, support, especially young creators, support them. They need it.

To doing the thing that like, the embarrassing failure where you’re standing there in a silly clown outfit, on stage, dancing, and nobody’s laughing. And it’s a… Comedians go through this all the time, when… They talk about this all the time, when they bomb, right? They, the act just doesn’t work, and you have to go through that. And you have to, you have to support the creators through that journey. In order to have great things, we need to support those folks. So, after shipping WoW, Wrath of the Lich King, again, many consider it to be one of the great expansions for WoW, you stepped down as WoW’s game director and switched to developing Titan.

Why Titan failed
Lex Fridman
This epic huge game that promised to be the, sort of the MMO to end all MMOs. I mean, it’s kind of a legendary vision for a game, right? It’s gigantic. With a lot of, like you said, a brilliant team, a team that’s now hardened and knows how to do a great game. But it was canceled after seven years in development. So, tell me, what was the vision of the game and what happened?

Sure. So, as we were experiencing success with World of Warcraft, there was this concept in the studio that WoW wasn’t gonna last forever.

WoW would be maybe successful for five years, and eventually kind of age out. And the studio would be in real trouble if we didn’t have another massively multiplayer online game sort of waiting in the wings. So starting around, I wanna say 2006, maybe 2005 the talk of starting a team really picked up momentum, and we were working on Burning Crusade. Rob Pardo took the helm to start sort of Titan development. We didn’t even really have a team then. And I remember being embroiled in Burning Crusade and going to Titan meetings, and Rob pulled a group from kind of across the company, and we started talking about what this next MMO could be and when it would get going. And eventually, it started in earnest, like real development, around 2007.

The first team members joined, and it was a real ambitious project, including like building a new engine from scratch. I think maybe the first team member was a guy named John LaFleur, who was just a stellar game programmer, and the engine which ultimately failed for Titan ended up becoming the engine for Overwatch, which is a great success story for him. And the idea behind the game, it was gonna take place in future Earth, and the players played as secret agents. And by day, they all had day jobs, and by night, they went off and did cool secret agent stuff. And the secret agent stuff was very first-person shooter, but over-the-top abilities like you would see in Overwatch, because that’s where they came from. And the by day stuff, we were gonna let you run businesses.

We took a lot of influence from games like Animal Crossing, Harvest Moon, the Sims. We had a brilliant game designer and game director named Matt Brown, who was the creative director on The Sims. He came over. And so we had this vision that there was gonna be all this like daytime business house stuff. You could build a house. You could live in a neighborhood. And beyond that, there was also a vision on the technical side, game design and technical side, that unlike World of Warcraft, which the modern day term for it is that it’s sharded. Mm-hmm. So meaning people play on different realms or servers.

In a WoW server, I don’t, I haven’t been on that team in a very long time, but back in the day, you might have 5,000 people on a WoW server before they’d have to spin up another WoW server. The big idea behind Titan is that everybody would play on one server. It was a one server, one world game, and the world was massive. It was gonna take place in future Earth, and we were literally building like, we had what we called Bay City, which was San Francisco. We had, you know, Hollywood, and then we had to build all of California between that, and we also wanted to build like Cairo and London. And there’s this realization of like, how do we connect all of these? The game had driving in it, like full-blown, like GTA-style driving.

It was such a gargantuan, huge undertaking with a, with a brand new engine, a brand new team, a brand new IP, intellectual property, you know, setting, which we really wrestled over. Like, the amount that the IP just, you know, trying to figure out, like, are there aliens or not aliens, you know? Like, all that sounds kinda dumb and fun, but when you’re building a game, like you, especially world-building, you have to have rules. That’s what makes world-building work, is that like, this exists in this world, and this doesn’t, and you know, why? It’s like, ’cause someone said so, and just the way it needs to be. But that development started in 2007, kind of as ideation, brainstorming, early work.

Really got going in late 2007, and then I had to ship Wrath of the Lich King and it was… We had the like, we always did like a champagne toast. I still remember it because it was Election Day. I think it was like Election Day and my birthday, and the day Obama got elected, and then I left the WoW team on that day. It was like memorable in all those ways. And then I joined the Titan team, and that game, we went on, like the fast-forward part of that is we shut it down in 2013.

Jeff Kaplan
That was one of the most painful development processes that I’ve ever been a part of, and probably, probably deep into 2009, I knew that the game in its current form could never ship and would never exist, and by 2010—like after numerous times trying to convince the powers that be that, like this game is not gonna happen, it’s in trouble. I remember going to Mike Morhaime in 2010, and, like, you’re going to the CEO of… You know, at that time, Blizzard was a big company, and I’m like, “You gotta shut us down. We’re just gonna burn money.”

What was your intuition about why? So like from my understanding, there was a few issues. So one, with such a gigantic world, which by the way, is a beautiful dream, this kind of universe simulator, because I love… Every game you mentioned there is great. I empathize with the dream. I would love to play that game. But one of the issues, as I understand, was it was unclear what, like, the quest flow is. Like what are you supposed to really do in this game? What’s the thing that connects all of the pieces together?

So it was a multifaceted failure for many reasons. Ultimately, the failure of Titan lies with leadership, team leadership, myself included. Like, there’s just no getting around that. And then on top of that, like, a lot of games you can point to as being like an engineering failure, like the, you know, the servers didn’t work— … or like an art failure, like no one responded to the look of the game, or a design failure, like the… it’s just not fun or it’s tuned poorly. We failed on art, engineering, and design, and I’m cautious about calling out art because some of the best art ever made at Blizzard was made for Titan. My criticism isn’t of the art that was created. My criticism is that we never had any art cohesion, so the art looked like it could’ve come from 10 different games.

Mm-hmm. And we should say it cost $83 million across those years. So a large team doing a lot of stuff, but not converging towards a game that could actually ship.

Correct. As, like, a game designer, I use semantics a lot and I like to define my semantics so people know where I’m coming from. Talking about ideas versus vision for a second, ideas are easy. Ideas, you know, I can have 10 in 10 seconds. You know, let’s make a 2D platformer about a mouse, you know, whatever. Like, you can… I want to… A secret agent by day is, you know, doing all this cool shooting stuff, by night is running a flower shop. You know, ideas are just infinite. At least on creative teams, you know, you have no shortage of ideas. What I call vision is the ability to not only take a great idea, but shepherd it into existence, and you’re doing that through inspiration first and foremost.

If you need a team to make it, you need a team to believe in the vision of the idea. And then there also has to be a technological plan for the idea. There has to be a design plan. There has to be an art style for the plan. There has to be a pragmatic production reality to the plan. And Titan kind of was like that was the hubris of Blizzard in that era at its height of, you know, we were over being hurt about, you know, World of Warcraft. I don’t know if people are gonna like it. And we were now in the era of, like, we made World of Warcraft. We can do no wrong. This next thing is gonna be the best ever. And there was also a lot of what I call anticipatory hiring-

… or, like, there’s opportunity hiring and then there’s also anticipatory hiring. I have the exact opposite hiring philosophy. I won’t hire anybody on any team until, like, we’re feeling like we gotta work overtime or, like, we might not ship if we don’t get, you know, somebody else in here. And Titan kinda had that hubris of like, well, we’re gonna build a really big world. We don’t know the story of the world yet. We don’t really have it mapped out what it should be like. We don’t have the art style really defined. We don’t know technically how we’re gonna make the art or what the constraints of it are, but we know we’re gonna build a really big world, so let’s just start hiring environmental artists.

And, like, in one year, we would hire, like, 70 environmental artists from all over the world. You know, we’re getting visas and, like, the top tier talent ’cause at the height of World of Warcraft and nobody knew the team that they were coming on. It was Blizzard’s next MMO top secret and they, you know, their first day at work, like some, you know, poor guy from Belgium just shows up and he’s at his first day at work and he’s like, “Oh, are we making World of StarCraft? Is that…” And they’re like, “No, dude. Let me show you it.” And he’s like, “What is this game?” You know? We were in that world, and we hired way too many people.

The right way to incubate a video game is you have the smallest group possible and you try to get the idea across with whatever technology you can get your hands on, using other engines, using art from whatever. You prove out that idea, and once you know what you’re doing, then you expand the team. You know the cliche of “idle hands is the devil’s work,” or whatever.

You have these, like, brilliant team, huge, and we don’t have a road map for what we’re making or how we’re gonna make it. And now you’re having to deal with all these people. Like, they’re coming into your office, you know, you’re trying to figure out what is the quest flow, how do I design the quest system for Titan, how can we prototype it? And we’re like, “Oh, this prop artist over here is running out of stuff to do. What props should he make? Should he work on Chinatown or the Hollywood set?” And you’re just making up busy work. The engine didn’t work.

When we would run play tests on Titan, we would have to tell the team, “Stop checking in because it slows us down.” We had this really great technical artist, a guy named Dylan Jones, and he was on Titan with us, and I remember in, like, the last days, we asked him, because he was a very active user—Titan editor was called Titan Edit or TED which is, to this day, TED is the proprietary tool for Overwatch, since Overwatch came from the Titan engine—

… which was Tank. And we said to Dylan, “I want you to log your uptime in the editor, in TED.” And in a 40-hour week, he was only able to work for 20 hours. And you can imagine, you’re building a team of the best and the—like, the best in the industry, and they can’t work. So not only are you just burning cash faster than anybody on the planet, it’s also, like, imagine having fighter pilots, but we don’t let them fly. Like, the creative frustration and the way that that manifested itself, and how demoralized the team got, it was a disaster.

Lex Fridman
And so many elements of that were done completely differently for Overwatch, which turned out to be this incredibly masterful execution on a short timescale with a small team with a clear vision. I read that sort of if you—if you were to compare Overwatch and Titan, sort of the defining characteristic for the Titan team, they said yes to everything, and the Overwatch team said no to everything. Meaning focus, like deep, deep focus on the execution of a very clear vision. And maybe that’s the process of designing games, like you said, is, you know on a team that’s full of incredible ideas because it’s creative minds, it’s constantly saying no. It’s a really painful process, but perhaps it—it is the responsibility of leadership to just keep saying no. Which sucks.

Being a creative leader, you’re in two modes. You’re pushing or you’re pulling, and whatever mode you’re in is the exact opposite of the team. When they’re not thinking outside the box enough or, like, elevating the vision enough, that’s when you’re pushing them. Like, “Come on guys,” you know, “don’t worry about the schedule. We got—” you know, “capture hearts and minds, inspire people.” And when they’re going a little crazy and they… Endless source of great ideas and really fun development, that’s when you gotta pull and say, “Guys, we need to ship this. The best feature we can add for the player is shipping.” That was a common phrase that we had.

Overwatch in six weeks
Lex Fridman
So when Titan was canceled, I mean that must’ve been a gigantic heartbreak for everybody. And there was this moment when the plan was for the Titan team to be disbanded and moved elsewhere, but you fought for keeping some part of the Titan team, the core of the team together, and Mike Morhaime gave you six weeks to come up with a pitch for a new game. And you’ve talked about this process, and you’ve mentioned that there were three possible ideas, directions you were thinking about. A StarCraft MMO, maybe an MMO in a new IP called Crossworlds, and then the third idea was Overwatch. Can you take me through those six weeks?

Jeff Kaplan
Yeah, the six weeks, it’s… It was supposed to be the greatest time ever if you think about it. Because you’re a game developer at Blizzard, and you get to come up with a new idea. So that sounds awesome, like, to everybody at Blizzard, to all game developers, it sounds great. But we were probably the most demoralized we’d ever been in our careers. At least I was, you know? I didn’t know if I was gonna be fired. I didn’t know if that was the end of my career at that point. And so it was like a really serious, kind of dire environment that this was happening in. And we were given two criteria that we had to hit for these pitches. The first one was that we had to ship within two years. And that is a very ambitious timeframe for any game.

Yeah, crazy. That’s crazy.
Yeah, crazy. That’s crazy.
Jeff Kaplan
But for a Blizzard game, it’s kind of insane. And then the second… Okay, the second is even more ambitious and crazy, was whatever we made, whatever we pitched had to have the potential to have World of Warcraft-like revenue.

Jeff Kaplan
And to date, at that point, there was one game that had World of Warcraft-like revenue, which was World of Warcraft, so… Immediately, I just threw out the revenue thing ’cause it’s all fucking Monopoly money to me. Like, this game money is… It’s insane, and I just don’t think about it. That’s someone else’s problem. But I did want to be as realistic as I could about the schedule part of it. So most of our team, the Titan team, was 140-some people. Most of that team got moved to go work on Heroes of the Storm, the D3 expansion, World of Warcraft, Hearthstone. So immediately, a large number of the team was gone. Then we had a bunch of, like, what we called temp loans-

Like, this game money is… It’s insane, and I just don’t think about it. That’s someone else’s problem. But I did want to be as realistic as I could about the schedule part of it. So most of our team, the Titan team, was 140-some people. Most of that team got moved to go work on Heroes of the Storm, the D3 expansion, World of Warcraft, Hearthstone. So immediately, a large number of the team was gone. Then we had a bunch of, like, what we called temp loans-
Jeff Kaplan
… people that someday were gonna come back to us, but we loaned off for, like, six-month tour of duty. And then there was a very small team. There was a group of engineers that was mothballing Titan, so it exists somewhere at Blizzard at that point. And they were also deconstructing the engine because they knew it didn’t work anymore, and to make a new game, it had to be way reconsidered to sort of what it is today. And then there was a very small creative group that was supposed to come up with these three pitches and given six weeks. And we just sort of arbitrarily decided, like, let’s spend two weeks on each pitch. The ground rules that I sort of led with is you have to be all in for the two weeks on the pitch. So if we’re…

Jeff Kaplan
You know, pitch one was a StarCraft MMO, and we have to live and breathe and want it more than anything. And I kind of warned everybody. I said, “At the end of this two weeks, you’re going to think this is the only game idea, and you’re not going to be invested in the next, but we’re going to throw it out as soon as we finish it and do the next one.” And the StarCraft MMO, I actually really loved that pitch. It was called StarCraft Frontiers. And the concept was, like, less of you’re playing, like, space marine. Like, it was less armies. StarCraft the RTS is always about the three races and the giant armies.

And kind of what made WoW wow and separate from the Warcraft RTS series was that instead of being, like, a footman in the army in World of Warcraft, you were like a lone adventurer, you know, make your mark on the world. So we had this idea, it was this old Chris Metzen drawing of a space prospector. And I love that idea that, like, somewhere out in, like, where all the giant StarCraft battles were happening, you know, thousands of Zerg and Protoss and Terran, there’s, like, this, like, lone prospector on some planet, like, going through, like, a mysterious dungeon- … you know, looking for minerals but finding monsters. Like, it was that kind of spirit of-

Lex Fridman
I didn’t even think about that because my intuition with a StarCraft MMO would be the soldier as part of the army, right? The prospector. That’s such a beautiful vision. Yeah.

Nice.

So then there was this Metzen picture of the prospector, and then two of the most amazing artists, Arnold Tsang and Peter Lee. Arnold’s the great character artist. Peter Lee’s the great environment artist. They did this concept art for Frontiers that was Metzen’s space prospector. He’s smoking a cigar-… and he’s got his foot on a Hydralisk skull.

And then there’s, like, a Medivac in the background, and they’re on this, like, big alien planet. And, like, that picture, you just wanted to like, “Here’s my money. I’ll pre-order now. Like, sign me up for that game.” That picture ended up being McCree from Overwatch. We redid it.

Jeff Kaplan
But, but yeah, that’s, that was where McCree actually came from. So that was the StarCraft Frontiers idea. We kind of, we, we went all in on the design. We had a world design. We had class design, like how, how the classes would work, what progression might look like. And you also have to think when you’re trying to design an MMO, like, what could expansions and live content be like? And we put together a really good pitch. We all knew there’s no way you can make this game. Like, this, even though it was more focused than Titan, it’s five years on Blizzard’s best day with nothing going wrong, in a perfect scenario, five years to make that game probably with, you know, 150 to 200 people.

Like, these 40 people are not making that game in two years. So as much as I… Like, again, that was an idea, not a vision, ’cause it lacked, it lacked the path to reality, you know? There-

Jeff Kaplan
Is it a cut scene? No one’s going to want a cut scene, but we should probably make it a cut scene because that’s easy. But well, we gotta have space flight. That… You’re adding, like, three years just by saying, “We gotta have space flight.”

So are you essentially, when you’re brainstorming like that, and by the way, such an incredible thing, for two weeks, you’re just really falling in love with the game altogether and trying to figure out if it’s actually possible. So if you’re developing that, are you just constantly trying to say, like, “What is the simplest possible thing we can do that’s a complete world?” Like, are you constantly trying to simplify or you’re allowing yourself to go big?

So when you’re brainstorming and you’re with the team and you’re the creative leader, it’s, “Guys, what’s fucking amazing?” What’s big? What do players need? There’s a Blizzard design value called “what is the fantasy?” What is the fantasy? You want to be in space. You want to be in the StarCraft universe, and then your job as the game director, and if you have a great creative director, art director, tech director, the director should be scoping it back into reality. The mistake I see on a lot of game teams is scope becomes a production problem. You give it to the project managers or the executives or the producers to say, “No, there’s not enough time.” Or, “You guys should hire more,” ’cause-

Like, what do executives, what do those types have at their disposal that they can hit you with meetings in Outlook and tell you that you can hire more people? That’s not really how you get the game made.

The scoping, your best-case scenario is when your tech director, art director, and game director are doing the scoping. Because then you know, like, this part we gotta spend big bucks on. There’s no getting around it. This part we can cheat. If you have a giant team and one guy’s job is just to make props, you know, crates and chairs, that guy’s going to make the… You know, that’s a AAA awesome developer who’s going to put his heart and soul into it. If you let him, he’ll take, you know, six weeks to make a crate. You have to have that moment where you’re like, “I kind of need 200 crates. So just spend, like, a couple hours on that one.” And that’s a hard thing to say to somebody.

Lex Fridman
You’re doing this kind of scope carving while also talking about “what is the fantasy.” So you’re, there’s a tension there that you’re constantly dancing with. So you’re, you’re allowing yourself to think big, but then scoping it down, and doing that, what, on a scale of days in this case, like?

Yeah. We had two weeks, so, and I don’t think we were… I was working on weekends, but we weren’t getting the group together. So it’s, you know, like 10 working days.

And then you, like, shut it off and go to idea number two?
Jeff Kaplan
Yeah. Idea number two was CrossWorlds. That was a Metzen vision for a universe, and, like, I’m glad Metzen’s back at Blizzard, and I hope they make this game someday. The way Chris described it was there’s a planet on the edge of the universe that’s like the Mos Eisley space port with all these, you know, freakish aliens and people from all walks of life-

… and it’s kind of seedy and criminal. And there’s traders and smugglers and diplomats and… But this one planet is sort of the planet that they’ve agreed to like meet on, and this is like the neutral place, and then the game was going to take place on that planet, so-

Jeff Kaplan
Yeah. So that was more of like a world IP driven one that was really inspired by Chris.
Yeah. So that was more of like a world IP driven one that was really inspired by Chris.
Lex Fridman
And that allows you to play with different characters, different… I like that, I like that idea a lot, because it’s the meeting place of different worlds, and then you can allow your imagination to drive what the worlds from which they came from are like. So you don’t have to design those worlds.

No, you don’t have to design them, but then they’re yours. Like, if the players really are reacting to, like, the Green People planet- … or whatever, and someday you’re like, “Hey, what expansion should we make?” “I don’t know. Green People planet.”

So it was actually that, it was CrossWorlds. We were working on CrossWorlds, and like the StarCraft Frontiers, you know, for Frontiers, we were having the class meetings, you know, how class progression work, like, the game designery stuff. And on CrossWorlds, we were having a class meeting of, like a big decision in, like, RPG type games is always: are you doing, like, skill based or class based?

Jeff Kaplan
And it’s usually some combination of those, but class based, you’re like choosing, “I’m going to be a warrior, therefore I use sword and shield, and I do these things.” Where more of a skill base is everybody’s kind of an avatar, and then the skills that you pick define, so I might take that I know how to use swords. So you’re kind of making those decisions, and with all things game design, there’s no right or wrong. It’s all trade-offs. So the trade-off decision we were making is like, “Oh, I think we want to be class based with this CrossWorlds thing,” and we were in a design meeting and one of my favorite designers of all time is a guy named Geoff Goodman. He was one of the original WoW encounter designers; he designed like Onyxia and all the big raid bosses.

Jeff Kaplan
Like, if someone has a favorite raid boss, Geoff probably designed it. And he just kind of off the cuff said in this meeting, he said, “I wish instead of making, like, six classes, I wish we could make 50 classes. And I wish instead of having, like, you know, 100 abilities on the classes, the 50 classes all just had, like, one or two things that was really interesting about them.” And then the class meeting ended. Like, we designed our six classes in that meeting, and then the meeting ended. And I was back at my desk, and it just stuck with me what Geoff had said about the way he wished he could design the classes. And then I also had… We had this directory of all the amazing Titan art.

Jeff Kaplan
And I started pulling up Arnold Tsang’s characters. Arnold’s vision and his art is second to none. And I started taking some of the old Titan characters that we had designed. We had a class called the Jumper, and the Jumper could, like, teleport forward and rewind time and come back. And the Jumper used dual-wield pistols, which was, at the time, designed after my dual G18s from Modern Warfare 2. It was my favorite loadout. I was just cribbing Infinity Ward. That’s where Tracer’s guns came from.

And we had all these, like, different guns, like, some that bloomed and some that, you know, had this, like, really crazy recoil, and we had other types of guns. And I took every version of, like, the Titan Jumper, and I just distilled it into what I thought was the best version of the Jumper, which was, you know, the dual-wield pistols, the blink, the recall, and time bomb. And then I took Arnold Tsang art, and I went, you know, to Arnold, and I’m like, “What if this wasn’t, like, a class? You know, who is this as a person, not a class?” And Arnold, “What if she’s British, and her name’s Tracer?” And, like, that was the origin of Overwatch.

Jeff Kaplan
And some of the pragmatic part of that was I knew that Geoff Goodman was gonna be on this team, and I knew that Arnold Tsang was gonna be on this team. And it’s a play to your strengths moment. Like, what could we make in two years with the talent we have, and what is realistic? Like, what could we realistically make? And so then I just sat there, and I sort of I went through a bunch of Titan classes with a guy named The Gunjack, who was… became Reaper. We had… Actually, the Ranger got split out and became 76 and became Bastion, of all things.

You’re describing the game of Overwatch where exactly that vision from that meeting- … came to life for you. As opposed to having a small number of classes with a large number of skills, you have a large number of heroes with each their distinct look, distinct set of skills.

Yeah, and the personality was a big part of it, like capturing… This isn’t some generic, the Jumper. It’s this person, Lena Oxton. You know? And she has a life, and we’re gonna, you know, make you interested in her.

Lex Fridman
Yeah, there’s, like, a deep backstory. And that’s also what’s interesting about Overwatch, is that backstory is not, like, revealed in a direct way. It’s, it sort of, like, seeps in indirectly throughout the game. So, the backstory is implied almost. And it’s told not directly. So, there’s a lot of ideas like this. And so you’re… This is the thing that the team converged to.

Jeff Kaplan
Yeah. Well, and it was funny because, like, we’re having these CrossWorlds. Like, people are, you know, writing design docs and doing concept art for CrossWorlds. And, you know, we’d have some brainstorm meetings every day, and I put together… It was a seven-page deck, Overwatch deck. And it was called Monetized Shooter at the time. And it just said, “Monetized Shooter.” And then the first slide was League of Legends plus Team Fortress 2 logos.

And then I had, like, six heroes, like, sloppily designed. And as everybody was working on CrossWorlds there were two, you know, co-leaders of that team for… There was, you know… Chris Metzen was there, and Ray Gresko. And I remember Ray coming over. Ray is, like, a phenomenal game developer of all time. He, like, wrote the Dark Forces engine, was the production director on Diablo III. He and I killed Titan. And then he’s at my desk looking over my shoulder, and he’s like, “Well, what are you working on? Is this the CrossWorlds pitch?” I’m like, “No, this is, like, another idea that I’m just working on on the side.” And I show him the seven slides, and he just looks at me, and he says, “Go show Metzen this.”

Jeff Kaplan
This is what we should make instead.” And then I went and I showed Metzen, like, “Hey, this is just an idea.” And then Metzen was like, “Yes. You know, this is what we should make.” And I showed Arnold, and it was Arnold’s art. And then Ray tells me, he’s like… ‘Cause we would- Every morning, we’d get the team together ’cause we were in this dire, you know, dire straits, and we’re midway through at that point. And Ray and a producer named Matt Hawley said, “Tomorrow morning at the meeting, you’re gonna pitch this Monetized Shooter idea.” It was called Monetized Shooter because originally when I pitched it, it was free to play and you had to buy the heroes, which is fucking terrible, but at the time, I actually thought that was a good idea.
This is what we should make instead.” And then I went and I showed Metzen, like, “Hey, this is just an idea.” And then Metzen was like, “Yes. You know, this is what we should make.” And I showed Arnold, and it was Arnold’s art. And then Ray tells me, he’s like… ‘Cause we would- Every morning, we’d get the team together ’cause we were in this dire, you know, dire straits, and we’re midway through at that point.

Jeff Kaplan
And I’m walking down the hall with Matt Hawley to go, like, pitch this to this group, you know, we’re supposed to be working on CrossWorlds, and they’re like, “You gotta pitch this idea to them.” And Matt Hawley stops me in the hall and says, “You, Jeff, you cannot go into that meeting. I refuse to put up a deck in front of the team where the first slide says, ‘Monetized Shooter.'” “They’ll hate that, and that’s not the spirit of who we are-” “… as, you know, creative devel-” And I’m like, “Yeah, you’re right.” Like, well no one was supposed to see his deck anyway.

You guys are all looking over my shoulder. He’s like, “You need to put a name on it.” I’m like, “It’s Overwatch.” Like, right on the spot, I said the name was Overwatch. And where that had come from was when we were working on Titan, I was really angry about this. We did this fake… I did not do this, another leader on the team did this, of this fake, like, we’re gonna put up whiteboards and everyone gets to vote for their favorite name for Titan. But the person who did it already had a name in mind- … for the game. And just kept pushing towards that name.

And the thing that got the most votes was Overwatch. Overwatch in Titan was, like, a police group, essentially. But somebody had written Overwatch on that board and it got the most votes. So I basically named the game Overwatch to, like, high five my team- … and kind of middle finger. Like- Don’t act like it’s a democracy when it’s not.

You know? So…

So it’s a middle finger. So Overwatch, and then the, I mean, the rest is history. So what, in that slide deck, did you already have a kind of crawl, walk, run idea of the way this would be developed?

… Besides dragging Arnold Tsang’s art, you know, desecrating it into my deck. We put together… We had this amazing game designer on the Overwatch team, a guy named Jeremy Craig who’s now actually game directing a game over at Bonfire. Jeremy, not only was he a great game designer, but he had the ability to sell things better than anybody else, visually. So Jeremy took my shitty deck, and then we had lots more, like, creative brainstorms and we thought through the game of Overwatch a lot more, and then he made this gorgeous pitch deck that we pitched. We first had to go through the Blizzard production and game directors for them to approve it and give it their thumbs up, then we had to go through the Blizzard executives, then we had to go through Activision.

And in that deck, because we had to speak to schedule, we had to speak to two things that were tough to speak to. One, we had to speak to schedule, and we came up with this concept of crawl, walk, run. We had identified the reason Titan failed is we just tried to run; we tried to come up with the next World of Warcraft. But if you think about World of Warcraft, it had Warcraft I, II and III to build upon to even get to the point where people gave a shit enough about that world to want to live in the world of Warcraft. So the idea was that instead of trying to cut right to World of Warcraft, let’s try to honor Warcraft I, essentially. So this first game is just to establish that there’s a universe you might give a shit about.

We also knew that the timeframe we were given of two years, there was no way to create a compelling PvE experience, so we just kinda randomly put dates in a slide of crawl, walk, run, thinking it was aspirational, and really, we were just trying to save ourselves. Like, don’t cancel us. You know, this team can make something great. The other part that we had to talk to too was, like, a mobile strategy. Like, at that time, it was like, everything has to be also on mobile, which I think is the dumbest thing ever. And so literally what we did is, this was Jeremy’s brilliant part, we had a picture with all the boxes and then one of them is, like, a tablet with just a fucking Photoshop of, you know, Arnold’s art on it. We’re like, “And also-“

Brilliant. But I think this crawl, walk, run idea is really nice. So the, the, the initial idea is you would have basically a shooter with all these different characters, all these heroes, and then the, the walk would be the PvE version of that, co-op. And then if people really fall in love with the world, then you build a big MMO around it. Quick pause for a bathroom break. Quick 30-second thank you to our sponsors.

Best Overwatch heroes
Lex Fridman
Choose wisely, my friends. And now, back to my conversation with Jeff Kaplan. And we should also say that there’s a whole world that was built around Overwatch. And one of the ideas was… So, Warcraft is a very particular kind of world. StarCraft is a particular kind of world. Diablo is a particular kind of world. And you wanted to bring Overwatch to Earth and make it positive. You give this talk where there was a lot of respect paid to the sort of dark, gritty, post-apocalyptic games on Earth. Also gave a lot of respect to the ultra-realistic first-person shooter games like Call of Duty. And you wanted to create something more that paints a vision of a near-term hopeful future, and fun, and more sort of surreal, versus like ultra-real.

So it’s interesting to talk through how a world comes to life. How you think about that world, how you create the tone of the game, how you think, how you craft in this vision. And not just, like, different characters like Tracer and so on, like what the personality is, but, like, bringing the world to life in which they will be. What was that process like?

The process was a blast. And, like, the goal was that bright, hopeful future. And the other phrase we used all the time on the team was, “A future worth fighting for.”

You know, if there’s gonna be all this fighting, like the… it kinda has to be worth it for something. Picking the locations in the world was the funnest thing. You know, there’s just a group of us who would sit around, and be like, “Where do you wanna go?” You know, “Santorini looks amazing.” And you’re looking at pictures, and like, “Let’s make that place.” You know in a video game people are gonna spend hours and hours in a location. Resist the urge to do the common, I call them the cargo container mazes, that you see in every game. And I know why they exist, they’re easy to make, but we kinda wanted Overwatch to be this world tour of great places that you’d wanna go to.

Or in the case of like Oasis, it’s like, okay, maybe Iraq, back when we were making this game, wasn’t the top of people’s list, but what is the bright, hopeful version of what that could look like? So we just really tried to sell this idea of these aspirational locations. One, just to get people thinking about different places on Planet Earth and how awesome they all are. But also, from like a pure game design standpoint, you’re gonna spend a lot of time in the environment, so the environment should be pleasing and not oppressive.

Can you go through some of the heroes that you ended up putting in the game? Maybe a good way to do it is, which are your favorites? And what’s from the best of your knowledge of the internet, favorites?

The OG, the cornerstone. You know, we put her on the front of the box. She was that moment of, “We should just take the best of the best,” and we know this gameplay is good and solid. And it’s so simple. Like, the mechanics are very easy to explain to somebody. It’s very easy to pick up. The first time anybody hits Recall for the first time and they try to wrap their mind around like, “Wait, does that mean if I…” You know, and they’re mapping out the possibilities.

And by the way, we should say that it’s a PvP game with six versus six at first, and where there’s three distinct roles that people take on on a team. And those roles, at first, I guess were not required. Like, you can reallocate those roles as you wanted. And then to maximize the fun, you add a little bit of structure. You enforce two per role, and the role being Tank, Support, and Damage. So, that. And then there’s all the kinds of heroes that are associated with the different roles, and people pick and there’s lore. And some people are probably like hardcore just one particular hero. And so there’s a lot of personality and story and community that builds around each of the heroes. And, but at the end of the day, it is just a fun shooter.

Yeah. Our goal was to pay homage to the shooters before us that we loved. There’s no way you can talk about Overwatch without talking about Team Fortress 2. Uh, Team Fortress started as a Quake mod, which was brilliant and I played tons of. Then there was Team Fortress Classic that came out with Half-Life 1.

And then Team Fortress 2, I think everything about it blew everybody away when it came out in 2007. And there’s obviously just huge influence there. But the shooter mechanics of Overwatch are… They hearken back to what people call the arcade or arena shooter genre. Which pains me ’cause I never… Back in the day, I didn’t think of Quake as an arcade shooter. It was almost an insulting way of saying it. But just the fast movement, really epic, over-the-top weapons. You have a low time to kill, or TTK, that players call it. Meaning you’re very survivable; you can take a few hits. Where, in a game like Call of Duty or Counter-Strike, if you get shot in the head, you’re just dead right away. So it was supposed to be this explosive, larger than life, fun, arcade-y shooter-

McCree. McCree is another, like, I’m somebody who’s attracted to the simplicity and design. And I did not design McCree’s six shooter. The way that gun feels is phenomenal, and to capture the spirit of that, we had a designer named Mike Heiberg design the High Noon ultimate. And then just all the care and love the team put in, like when he does the ultimate, we roll a tumbleweed across the screen like every time. It’s a very simple hero, but the simplicity is what I like best in design.

I’m not a fan of when somebody starts explaining, you know, in any of these games, whether they’re MOBAs or hero shooters, and they start, like, “This guy throws orbs, and he throws three orbs, and then he runs out of his orb bank, and then he can call the orbs back, or he can catch the orbs.” And my head is spinning, and I’m like, “Just give me a fucking good gun.” You know? And I’m done.

Jeff Kaplan
Reinhardt was actually my main. So I played the most of Reinhardt. That was another amazing Geoff Goodman design of this guy who just has a shield. As soon as you give somebody a shield, they know what to do. They go into protector mode. The shield was designed to shoot through. The shield has since been copied by like every hero shooter since, and even non-hero shooters. And then he just has a giant rocket hammer. And he does a charge ability. It’s really interesting where the charge ability came from. I was playing a ton of Left 4 Dead 2, and you could play in versus mode where you could be the enemy zombie guys.

And there was an enemy boss zombie called The Charger who had that charge ability. And I thought, the reason that ability was so cool is because it’s a commit. Once you press the button, you’re a runaway train. And watching Reinhardts charge to their deaths is kind of hilarious, and it’s what separates a great Rein from a shitty one.

The challenge of matchmaking
Lex Fridman
You’ve explained that the Overwatch matchmaker process is designed to keep players at a 50% win rate. I think it’s just a fascinating topic. Not to get too philosophical, but you can’t have the up without the down, hence the 50%. Can, can you speak to the complexity of like what makes a good matchmaker?

The matchmaking systems are some of the most complex design and engineering tasks you’re ever gonna tackle. And they’re thankless. It’s, it’s very hard, too, because I think most people, and they’re not being disingenuous, like if you ask a gamer, “What do you want?” They’re like, “I just want a fair match. Like, just make it even.” And the reality of what they want is they want a match where they’re slightly better than the other guy.

Like, they want it to feel like it was close but then win. And you can’t architect that. Like, there, it’s, you know, it’s a zero-sum situation, so there’s gotta be winners and there’s gotta be losers. The other really core problem, and we would study this all the time when people would complain. You know, you see a Reddit post, and somebody would say, “I had a six game losing streak. This is so fucked. It’s the worst matchmaker ever.”

But we would look up that person’s account. I would do that all the time. I love looking up people’s accounts and seeing- … what would happen. It’s like, yeah, he had the six-game losing streak. He had an eight-game winning streak before that. There was no post about how awesome is this. And the human psychology doesn’t allow for that. One of my hindsight regrets about Overwatch, and this is, I think we did the right thing in the moment. It’s you know, like, I wouldn’t go back and redo it, but if I was making a hero shooter from scratch today, I would make it less team-focused. And we put all of our eggs in you noticing if the team won or lost.

And we downplayed your individual contribution as much as possible. There wasn’t a scoreboard. We had a medal system, but the medal system was, in my opinion, it was not good because the losing team got medals and the winning team got medals. And on the losing team, they would use that. They would weaponize it against their teammate. “Well, I’m the top kills, and all you guys are making us lose.” And it’s like, “Okay, you’re the top kills by like one, and you guys still lost.” So I would, if I was to redo it today, or for any aspiring hero shooter makers out there, I would actually downplay the team factor, and try to put more focus on individual contribution.

Because that’s just how people play. They’re, they’re selfish. And I don’t mean that in a bad way. It’s just, it’s that human nature, they can’t help.

And in terms of how they experience the game, in terms of how they derive joy from it, or how they see the challenge of the game is individual. Even when you’re on a team, you’re still feeling- … it’s individual, a fundamental individual experience. Let me, as a small aside, before I forget, since we mentioned first-person shooters so much, outside of Overwatch, what are some of the great shooters of all time that you’ve played?
And in terms of how they experience the game, in terms of how they derive joy from it, or how they see the challenge of the game is individual.

Okay. Can you… Okay. A lot of folks have written to me that I need to play Rust, the video game. I have not even looked into it. Somebody on Reddit said it has a steep learning curve. I would like to give it a chance because you have to me spoken so highly of it. So can you explain Rust?

Yeah. Rust is an open world game. It’s a procedural map, so it means that every time it’s different. You’re always on an island, and it resets every month. So-

Jeff Kaplan
Yeah, and then you build what Rust players call bases, and you upgrade the base, and you try to make the base as safe as possible to store your stuff, and then you can make explosives and blow up other people’s walls to get into their base where they’re keeping all their best stuff and take all their shit.

You know, like, you spend a week building the world’s most perfect base and getting tons of loot, and then it… There’s what’s called online raiding and offline raiding. Online raiding means that my enemy is… I can see that they’re in their base right now, and I’m gonna try to attack them while they’re in their base. Offlining, which is, like, all Rust players will say you’re the scum of the Earth if you offline someone, and then all Rust players also offline people all the time. Yeah. It’s-

Offlining’s when, like, “Hey, I think that my neighbor logged off for the night. You know, they just played six hours. I’ve been watching them, and now there’s no activity in their base, so I’m gonna, like, blow up their walls and take up all their stuff when they’re not here.”

You know, there’s a lot of haters. Like, Call of Duty 4 and Modern Warfare 2 were the pinnacle of Call of Duty, with Black Ops being a very respectable, you know, third. But you’re never gonna get a better gun feel from a game than Call… Like, just study the visual effects, the animation, the modeling, the sounds. Every aspect of shooting a gun in Call of Duty is so masterfully done. And then the maps, like, the flow of the multiplayer is just great. Like, there’s… There’s a map called Crash from Call of Duty 4 that Aaron Keller and I… Aaron’s now the game director on Overwatch. We just sat and studied that map, or Terminal from Modern Warfare 2. Just studied the maps of just, like, this map design is off the hook. So Call of Duty is definitely up there.

So even though you were not thinking about it, Overwatch ended up being a gigantic success. So did you start thinking about, in this framework of crawl, walk, run, about the walk, the PvE piece?

So, Overwatch 1 didn’t ship until 2016. So before Overwatch… And it wasn’t like work in earnest. It was like pitching the game. I remember I spent a lot of time… It was myself, Chris Metzen, and Michael Chu sort of brainstorming a framework for what, like, a campaign could look like. And we had this idea of, like, a cooperative PvE shooter. And we actually pitched it to the team before we launched because we were trying to put a bunch of runway in front of us. That worked against us, and it’s one of my biggest mistakes I’ve made as a creative leader in my career, was Overwatch 2. There were two points of failure for me.

Jeff Kaplan
The first was, I had people on the game team who didn’t like PvP or competitive shooters, and they really loved the Overwatch universe and wanted to play these characters and heroes, but they wanted to kind of do it on their own terms in like a PvE setting. So even though Overwatch is this like runaway success and everybody’s talking about it, they felt like they couldn’t really engage with it. And so like people on the dev team are like, “Okay, thank God we, you know, shipped that PvP thing-“

Jeff Kaplan
“… When do we start work on this other thing?” So that came from a genuine place of excitement. And then the other point of pressure was from the executive team, and this was both the Blizzard and more so the Activision executive teams, and they started really putting the heat on, “Well, you said Overwatch 2 was gonna be out in 2019.” And they’re referring back to these slides that were just crazy dates. Like- … it was… You never want to put a PowerPoint deck in front of a corporate executive. Like, you might as well etch it in stone and come down from the mountain on it.

So the executives started getting really angry at us that Overwatch 2 was slipping, slipping. And so when Overwatch 1 took off, I remember very early, we were in like May of 2016, and that year the Olympics were gonna be in Rio, I think. And, you know, I always like to pay, pay respects to, like, when a big event is happening, I’m like, “Hey, we should do, like, an event for the Olympics.” You can’t call it the Olympics or else they sue you, so you just… Even though you’re advertising for them to a bunch of kids who want to play video games and not watch the Olympics. But we also had like these two developers, Mike Heiberg and Dave Adams, like worked on this quirky… Like, they made soccer in Overwatch. We called it Lúcioball.

And we do a live patch that’s the Summer Games. It’s extremely successful. And then after that, we’re like, “Yeah, let’s do… Halloween’s coming up. Let’s do a Halloween event. How cool will that be?” And our fans just loved these events, but there were two groups that were struggling with it. One was that group I told you on the dev team who was like, “Oh my God, you guys are over-scoping the patches. Why are we doing this Halloween event? We should be doing… We should start work on Overwatch 2. We shouldn’t be this focused on the live game,” which was fucking nuts. Like, that was just crazy. There’s this phrase of catch the wave, ride the wave. Most games fall off the back of the wave. They don’t catch the wave. No one plays it or plays it for two weeks.

Yeah. We had a coalition on the team that was… really wanted Overwatch 2 built instead of the live events. And then the executive pressure became monumental. And what would have been correct was to do more world events, like keep it going, but the major derail was Overwatch League. And we really like… The, the weirdest part about Overwatch League is I believe in it. You know, I helped pitch it along with some other people. We thought it was like the future of esports and doing regional-based teams, ensuring minimum player salaries and player protections. Like, there was a lot of very good about Overwatch League.

Jeff Kaplan
Yeah. The teams part of the dream was more of like regional based, player protection, try to make esports more of a first class citizen, because there were all these stories about like shady teams, you know, screwing their players over. Where it got away from us was there was a lot of excitement about Overwatch League, like too much so, and then it got over marketed to the people buying the teams. They went on this road show where they had a deck basically, and like you could put anything in a deck and sell anything, and they were pretty much selling the Brooklyn Bridge, that Overwatch League was going to be more popular than the NFL.

And we got a bunch of…… billionaire investors in these teams. And when 2018 started, like for example the day I got back, they said, “We signed this huge deal with Twitch for streaming of Overwatch League,” like a media rights deal. And that means that here’s all these commitments we made for Overwatch League of like in-game stuff that had to exist. Like a lot of it was integration with Twitch and camera control and that kind of stuff. The other part of it was a bunch of skins and you know, uniforms for all the teams, which was not just getting the art in the game, but there was huge technical challenges to, like, how all that worked and was efficient and hit the right, you know, memory footprint and all of that kind of stuff.

And so all of your plans at that point kind of go out the window. Like you’re not gonna work on new world events. You’re not really even focused on Overwatch 2, you’re just kind of treading water. There was a lot of talk of like, “Oh God, you know, the deal, like, the deal didn’t go well and we’ve got to do make goods to make the deal better for them.” I’m like, “Just give them some money back, you know?” Like, if you… The deal isn’t what people wanted, like, putting it on us, the Overwatch team, to, like, support this beast.

And it was a great idea that the wrong instincts and sort of, I don’t know how to phrase this in a way that’s not damning, but there was too much focus on, “Let’s make lots of money really fast.” And a lot of people got dragged into it. And while Overwatch League was great for Overwatch in terms of the players that it brought in, and the Overwatch League players, they were awesome. I love them. The Overwatch League staff at Blizzard, some of the nicest, most motivated, great creative people- … like all of these organizations got built and they were all great, but it was a house of cards waiting to fall.

The financial reality kicked in, where these teams now, we didn’t just have, you know, executives at Activision and Blizzard who cared about the bottom line of Overwatch. We had all these people who basically invested in the game, and then they started to express their opinions. Originally, the business model was going to be that they were going to do in-person events and there’s going to be big ticket sales and then merch, you know, and all of that. And I think really quickly everybody learned like, yeah, we can’t do in-game events when you have a London team and a Shanghai team and, like, how does this work? So that fell apart super quickly. The merch was good, but it wasn’t going to be making NFL level money-

… whatever insanity anybody thought that was going to be. So everybody quickly defaulted back to, “Hey, didn’t Overwatch make like $500 million just in the live game last year? What can we sell and what can you give us?” That pressure comes onto the team, and then the pressure to ship Overwatch 2 and all the care and love that we had for, like, the live game and the live server, “Let’s just make events and new heroes and new maps,” we’re losing all these resources. And it got to the point, you know, my exit at Blizzard, I believed in Overwatch 2. I think we could have made a great game. I have a lot of hindsight of, like, how I would have designed that game differently with what I know now versus what ultimately we didn’t ship.

I think everybody would have loved to have played it. And there’s a misconception online that all I cared about was PvE and I didn’t care about PvP. All of the Overwatch 2 PvP maps were something that I said to the team over and over, “We have a PvP audience. If we get anything right, it has to be the PvP.” We would be lucky to welcome these PvE players, but that’s not guaranteed. So it was never a PvE only focus.

Yeah. And what eventually broke me was it used to be like in 2016 and 2017, I felt very in control of the Overwatch team and the direction of the game as a game director, you know, working with Ray Gresko as the production director, it felt like we were running Overwatch.

And we were very, very successful and doing a good job. And I think the fans were happy. And then as we transitioned, you know, Overwatch League was the best intention. You know, my parents always say, “The road to hell is paved with good intentions.” That was the Overwatch League, and it ended up being an albatross. And then Overwatch 2 is the same thing. And what it boiled down for me, like what sort of ultimately broke me in my Blizzard career was I got called in the CFO’s office, and he sits me down and he says, he gives me a date, which at the time was 2020 and was going to slip to 2021, but at the time, it was 2020.

And he said, “Overwatch has to make in 2020, and then every year after that, it needs a recurring revenue of…” And then he says to me, “If it doesn’t do dollars, we’re gonna lay off a thousand people, and that’s gonna be on you.” And that was just the biggest fuck you moment I had in my career. It felt surreal to be in that condition. And as somebody who’s worked on a lot of games, made a lot of games, you get in these meetings where they’re like, “There’s Fortnite, has 1,400 people working on it. If you just hire 1,400 people and make it free-to-play, we’ll make that money, right?” And that was… I had believed I would never work any place but Blizzard. I loved it. It was a part of who I was and I felt I was a part of it, and I literally thought I would retire from the place.

I never thought the day would come, and that was it. I was like, we’re done here. Luckily for Blizzard, that CFO is no longer there.

I mean, Blizzard is one of the greatest companies in the history of Earth. They’ve created so many incredible video games. It’s so difficult to create so many hits, and they were done not by chasing money. They’re done by small incredible teams, the hodgepodge that you describe taking big risks and falling in love with the thing they do and then just chasing it, working extremely hard. And just because you figured out a way how to make a lot of money doesn’t mean it’s not at the core this incredible creative journey that’s incredibly difficult to pull off. And just because you got a bunch of really smart creative people who have somehow figured out how to pull it off multiple times in a row doesn’t mean you can just treat it like a machine.

Every single time, it’s this beautiful journey of hodgepodge of weirdos working together, and weirdos have to run that thing. If you have, ever have a chance to create something special, you have to have weirdos at the helm. And the degree to which you don’t have weirdos at the helm, creative minds at the helm and you’re a businessperson at the helm, get out of their way, right? You can’t, you cannot have the meetings like you’re describing. And I don’t just speak about this particular company. It’s just the entire industry. I just, there’s so much joy to be had if we keep creating great games, and I just hope we get to see those great games.

I think there’s a message to creative people out there and people who make stuff. We’re generally—we’re so focused on the love of the craft that we get lost in it and we love doing it and we’re not cutthroat and we don’t have that kind of ambition. We have a different kind of ambition. But there’s this whole world, especially as soon as you’re lucky enough to have success, that are very cutthroat and very ambitious. And for whatever reason, we keep giving ourselves to them, and we need to stop giving our so… World of Warcraft, when we made it, there was no CFO at Blizzard. You don’t need a CFO to make World of Warcraft. You need artists, engineers, designers, producers, and an audio team.

You don’t need to bring in… Just because you’re making a lot of money doesn’t mean you need to now start adulting by bringing in a CFO. You can figure it out.

And there are great finance guys. Like I’ve worked with finance guys who get it and get out of the way and respect, and they’re gamers, and they sort of understand, but like, I wish developers would understand their own value more and stop handing the golden goose to people who don’t deserve it.

How painful was it to say goodbye?
How painful was it to say goodbye?
Jeff Kaplan
It broke me. I think after you’ve been at a place like Blizzard, which I love Blizzard. To this day, I have nothing but warm, fond memories. I mean, there’s those moments where you’re like, “I wish that hadn’t happened,” but on the whole, that place is mecca for game development, and everything I have is due to Blizzard. They provided for me and my family, made me the person I am, so separating from Blizzard was one of the most painful things. And I was very sad when I resigned, and I didn’t realize how broken I was until recently, like the mourning, grieving I had gone through of like… I think I’m a little fucked in the head for not being there any… How could I give that up? How could I not be there anymore? It was—it was really, really painful leaving.

Can we just speak to, I don’t know, I don’t think we can give enough love to Blizzard. It’s a legendary company. For me personally, for everybody, for millions of people, created some of the greatest games ever, Warcraft, StarCraft Universe, Diablo, WoW, Overwatch. What made it such a legendary game company? Just looking back at the whole of it?

The start is Mike, Allen, and Frank. It was run by three gamers. They were, all three of them, programmers. They made the games before they just ran the company, so they knew what each of us as developers beneath them were going through, and they protected us. They shielded us from all of the nonsense, and even when they would align with a businessperson, they had a COO in the early days named Paul Sams, and Paul protected us.

You know, they just, they found great people who got it. The company when I joined was, like, 95% developers and, like, 5% operations. It’s, when I left, it was, you know, 50/50, and that’s like a 4,500-person company. That love of the games and the respect and good treatment for game developers really turned it into the place that it was, just the commitment to excellence, the high-quality bar and then finding these passionate people like Chris Metzen or Sam Didier, they were, like, the visionaries of early Blizzard, Allen Adham, of just these worlds that we’re still making and we’re still playing in today. It was infectious and it was inspirational, and you wore the Blizzard blue with an esprit de corps.

Like, you felt proud to be part of it and you felt like you had made it to be there, and everything you did, you did wanting to respect and honor those who had come before you. I know that sounds almost cheesy saying it that way, but it really had that sense of reverence, like you knew you were part of something special. You didn’t take it for granted.

Yeah. That’s the sense. Reading everything, that’s the sense I got. Everybody there was a part of it that truly, truly, truly honored that time. Just to, just to take a small slice, what were some of the brain… So you mentioned Chris Metzen. You gave so much love to so many people on the team, but I gotta ask about Chris Metzen, who I would, by the way, love to do a podcast with at some point. What were the brainstorming sessions with him like? It seems like those are pretty awesome.

They were the best. Like, you could walk into a room. Like, the way I would work with Chris is early on when I was more junior, it was just sort of getting creative direction from him. “Hey, Chris, I’m about to work on this zone called Westfall. What are your ideas? You know, how could I capture them in gameplay? Well, that won’t quite work. How about like this?” It was more like that. Later on, like, I, I still remember the first discussion I ever had with Chris about Wrath of the Lich King, I went up to his office like, “Hey, we’re, we’re finally doing it. We’re doing the Northrend expansion. You know, what excites you about Northrend?” And that’s all you had to say. And he would draw a map and he’d start pulling up old, like, Warcraft II and Warcraft I manuals- …

and, you know, showing you, like, pictures he and Sammy had drawn and, like, maps and, and he, all of it, he would just go on for an hour and then I would sort of digest. I’d just listen, taking constant notes. I’m photographing his whiteboards all the time, and then I go back and start to put those into design flow of, like, “Okay. What, what’s a zone? What’s a dungeon? What could be cool? What should come first? What should come last?” You know, Lich King, for example, we wanted to try a very specific design to counter a problem we had in Burning Crusade, which is everybody entered through the Dark Portal through Hellfire Peninsula, all the server programmers hate you because everybody loads into the same zone at the same time. Lich King, we split them up for better player flow.

Plus, it’s more interesting the more choice you have. You know, Sid Meier says, “Games are a series of interesting choices,” so we give them two starting zones, but that was the flow with Chris. And so often we would just, like, okay, in that first meeting, Chris had put a zone called Grizzly Hills on the board. Well, I don’t know anything about Grizzly Hills. “Hey, Chris? Talk about Grizzly Hills.” If you didn’t interrupt him, he’d just go for an hour. And you have no idea how much of it, like, he had pre-thought about or had existed in previous lore and how much of it he was just making up on the spot. He’s just that charismatic and captivating.

Creating these worlds and being able to- … brainstorm through them and together, I mean, that is what you’re doing. As a consumer of those worlds, you kind of take it for granted that they’re incredible, but, like, you’re crafting them. Like, you’re looking at a blank sheet of paper and then together coming up…

My job, as I saw it working with Chris, was I had to on World of Warcraft specifically working with Chris, is I was like the translator into gameplay of what Chris wanted, how to get it to play like how Chris wanted. So my favorite story is we’re working on Burning Crusade and we’re in this meeting and Chris is like… He’s the gentlest, sweetest guy, but because he carries himself with such confidence and everybody’s in awe of him, the junior developers get kind of intimidated by him. So we’re in this meeting and we’re talking about Silvermoon City because we’re introducing the Blood Elves, and Chris is like, “And Silvermoon City’s got the tallest fucking tower in all of Azeroth. I mean, it is the tallest thing. You know, it’s mind-blowing, the awe of it.”

Only the blood elves could build it.” Fast-forward like two weeks later. I’m walking through the hall and I see a bunch of level designers and artists are all like crowded around the screen, and on the screen they’ve dragged Blackrock Mountain and Karazhan and the Stormwind Cathedral. I’m like, “What the fuck are you guys doing?” And they’re like, “Well, Chris said that the Silvermoon Tower had to be the tallest thing in World of Warcraft-” “… and so we’re measuring how tall all of these other things are so we can make the tower taller.” And I’m like, “Guys, Chris doesn’t know how tall the Burning Steppes, you know- … and the cathedral in Stormwind- … is. What Chris means is just make the tower really fucking tall.”

“You don’t need to measure it.” And they’re, “Oh, okay. That’s okay?” Like, “Are you willing to take the heat if he—” I’m like, “I’m willing to take the heat on this one, guys.”

Diablo IV
Lex Fridman
Yeah. And I also just personally have to give all the love in the world for the current Diablo IV team, because I’ve spent, most recently out of the Blizzard games, I’ve spent a huge amount of time in Diablo, and they’ve created some… And it’s not just the loot, all right? It’s the, the whole experience, the art, everything together. And the seasons they’ve created, they’ve created a really wonderful world. So I can, I could see, I could feel how much effort goes into that.

They’re crushing it. And I think Diablo IV in like modern times is one of the best worlds that they’ve built. And they know, they understand Diablo players. Like that community is so hard and so demanding, and that team is amazing.

Yeah, there’s a lot of richness. It’s like there’s this really… I mean, I don’t know how often you get that, but it’s really the perfect Diablo game. They’ve really like evolved a lot, grew a lot. So there’s this whole mathematical component of just so many numbers everywhere and it’s all balanced really masterfully. And then, of course, you have to come up with new content with the seasons and they figure out ways to do that, and at a crazy pace. And still make it super fun.

Getting back to making video games
Lex Fridman
And for me personally, like I said, the co-op, the couch co-op experience has been really… like that aspect of it is really great, just all of it. It’s one of the greatest games in recent history. One of the things I wanted to mention, ’cause this is a powerful speech, is sort of instead of doing some kind of a corporate goodbye as you were leaving Blizzard, you allegedly shared with your team a video of David Bowie giving advice. And people should go watch this clip. But if I may read it, Bowie says, “Never play to the gallery.

Always remember that the reason that you initially started working was that there was something inside yourself that you felt that if you could manifest in some way, you would understand more about yourself and how you co-exist with the rest of society. I think it’s terribly dangerous for an artist to fulfill other peoples’ expectations. I think they generally produce their worst work when they do that. And the other thing I would say is that if you feel safe in the area that you’re working in, you’re not working in the right area. Always go a little further into the water than you feel you’re capable of being in. Go a little bit out of your depth.

And when you don’t feel that your feet are quite touching the bottom, you’re just about in the right place to do something exciting.” Speaking of which, you are just about in a place to do something exciting. After leaving Blizzard you told me that you tried to take some time off. How did that work out for you?

Not so well. My wife, who is wonderful, told me I needed to take at least a year off and just, you know, I’d been going really hard. I’d gone 19 years barely taking vacation and I let Blizzard consume me. And, you know, I was crushed by leaving because I loved the place, and I didn’t know what to do with myself. I was pulling weeds in the backyard.

Literally. Gardening.
Literally. Gardening.
Jeff Kaplan
Yeah. Well, she won’t let me garden in the garden ’cause that’s hers- … but I’m allowed to pull the weeds. So I got very good at that. I was very proficient. And then of all things, I cracked out on Call of Duty: Black Ops Cold War and I unlocked Dark Matter Ultra, which I’d… that’s like a crazy achievement to do in that game.

So I did that, and then I just, I couldn’t help it, like it’s how I’m programmed. It was like, at this point, it’s late spring, early summer and I’m just sitting in the backyard and I just started writing with Notepad about, “Here’s a game I want to make.” And it was so terrifying because for 19 years I had worked with the greatest developers, I thought, in the industry. And, you know, there’d be moments where it’s like, “Okay, I wanna do like a game world map.” Like, “Hey, Erin, you’re amazing at making game world maps. Like, you do that.” And you know, I, like, “I need some story hooks. Hey, Chris, what do you think would be cool here?”

Like, you know, it’s so collaborative and I was surrounded by the best of the best, and there I was by myself. And I was out there again, and I loved it. It brought all the joy of game making. I thought games were no longer fun to make because it was only about business, and somebody’s asking me for unreasonable amounts of money and unreasonable amounts of time. And I had forgotten the pure joy of the craft of making games, and I was designing, I was going on, I was watching YouTube videos to learn Unreal and Adobe Illustrator and all these things to like help me make games, whatever, Blender. Um, I had no right to be doing any of that, and it just felt so amazing to do it. And I sort of realized, I came to two realizations. One, I never wanna work for someone else again.

I thought games were no longer fun to make because it was only about business, and somebody’s asking me for unreasonable amounts of money and unreasonable amounts of time. And I had forgotten the pure joy of the craft of making games, and I was designing, I was going on, I was watching YouTube videos to learn Unreal and Adobe Illustrator and all these things to like help me make games, whatever, Blender. Um, I had no right to be doing any of that, and it just felt so amazing to do it. And I sort of realized, I came to two realizations. One, I never wanna work for someone else again.

I never wanna create something and then have somebody take my baby away from me, you know? That’s really hard when that happens, and it’s sort of happened a few times now, you know, where you have to just let something go that you created. And I wanted it all to be focused on the craft of making games, the art, programming, design, audio, you know? Like, just not about the bullshit of the games industry. I’m not interested in the games industry. I’m not interested in the business of games. I’m not interested in the entertainment industry. It’s just game jamming, making stuff that we’re gonna play together. And around that time, my I call him my development soulmate. There’s a programmer named Tim Ford.

He reached out and he’s like, “Hey, man…” He was like an associate tech director on Overwatch at the time. And he’s like, “Yeah, I don’t think I can do this anymore. It’s just not like it was, you know, I just handed in my notice.” And I’m like, “Whoa, you know, well, if you wanna do something together, like fuck it. Let’s take a stab and, you know, just see what happens.” And Tim came over to my house, and well, before that, he says, “My last day’s on Friday.”

Take a month off, you know? Meg, his wife, will appreciate it, you know? Just go pull weeds in the garden for a while.” And he’s like, “I’m a programmer.

It was, this was April of 2021 and investment money was nuts. Both like the VC money and the strategic money was crazy, like the, especially the Chinese companies, because apparently they weren’t getting publishing numbers in China or something. The whole economy was crazy, and so just everybody was trying to throw money at me, which was a very good position to sort of be at to start a company. So what Tim and I did was say, “We’re not doing this for money, but here’s the game we wanna make, and it’s gonna take this many developers, and we think it’s gonna take this length of time, and that means the budget is this.

I don’t know if this is something that you can talk about, but I got a chance to see the game for a few hours, and I have to say it’s incredible, Jeff. Like, it’s incredible. But I almost immediately fell in love with the world and everything I saw. See, I’m tempted to say some of the things I saw but it’s just an incredible game. So how much can you talk about it? Do you know what it’s going to be called? Can you talk about that? Do you know about the company? Are you allowed to say any of that?

And the company name has a deep meaning to me, which I’m happy to explain later if you’re interested. And the game name that we’re working on, it’s called The Legend of California, and it’s an open world game. People are gonna call it a survival crafting game. People like to compartmentalize these. I think it’s an action game. It’s a game that takes place on a mythical island of California.

The theme of the game is very weird. We’re not trying to make a historical game. There’s no historical accuracy to this. In fact, the island when first discovered is uninhabited. That’s already not true. As we know, there were lots of people in California. It’s an island, which we know is not true. We want it to feel authentic to that time period because we think that time period is cool. Prospectors, you know, cowboys. Like, it’s a really fun thing for us to explore, all of those themes—people in mines. We wanna build mines and we just wanna create a world that you can live in. I love creating worlds. Everything that I’ve worked on before, from World of Warcraft to Overwatch, it’s always been, how do you create this place for players to escape to? So.

Jeff Kaplan
Yeah. As a world, we handcrafted the world, so like the shape of California is always the familiar shape of California, except it’s an island. So, you know, there’s no Nevada on the eastern side. We handcrafted all of that. It looks gorgeous and places like Yosemite are where you would expect Yosemite to be. And so all of those familiar landmarks are there, but then we have like dozens of points of interest, and those move around the map in, depending on the map seed. And the map is also tiered in terms of difficulty. We don’t really have levels in this game. We have tiers, and there’s only four tiers right now. Maybe, maybe that will change. But the way that the map tiers itself each time changes with every world seed. So not only…

Jeff Kaplan
Any server that you join will have a different seed in terms of how the tiers play out. So, Mojave might be the easiest newbie area on your server, but on my server it’s an endgame, tier four area. But all of our notable points of interest also move around. So, we have a really amazing point of interest that we call Dread Rock that’s inspired by Alcatraz. And like, sure, sometimes it’s in San Francisco, but sometimes it can be sitting in the middle of the Mojave Desert also.

Mm-hmm. It integrates it into the environment, to where it makes sense- … to be in that environment. And like you said, so much of what makes a world is sound and lighting. And that, that’s definitely a thing that I’ve noticed. I mean, it’s probably the most beautiful sunset and sunrise I’ve seen in a game.

But like… I see a Bierstadt painting, and I wanna walk around that world. I wanna see what’s around the corner. And our lighting artist, Mike, he, you know, he sees these pictures, and he’s like, “Okay. Yeah. Hold my beer.” Like, “I’ll make it look like that.” And he, and he… We are all blown away by the, like, how much impact just the lighting has. And I’m not an artist, so I don’t think about things like the color theory, the lights, the clouds, what all of that’s bringing to this. I just know I want to live in that world, and these are the types of worlds that we want to make.

You’re making, like, a bright, aspirational future team-based hero shooter, right?” And I’m like, “Why would I want to do that?” I felt like, first of all, respects to Blizzard, and I don’t want to try to crib Blizzard and make a pseudo-Blizzard game, you know? This is… I want to make a Kintsugiyama game, you know? Me and Tim and this crack team, you know, we’re only 34 people. We want to define what a Kintsugiyama game is, and this world seemed so inspiring to us, you know? The setting is really interesting. You know, I think California can be a game world.

I think we can make it beautiful and interesting. We don’t have to follow history or geography. We can kind of do a spin where, you know, it feels authentic. We can have guns that feel like they’re kind of from that time period, but we’re not spaceships and aliens and steampunk. That’s what we would have done at Blizzard. We’re gonna be a little different here. So, the tone of this game, you know… Metzen would describe Blizzard as the hero factory. You know, we make… And what he means by that is not only are we making heroes, but we make the players into heroes.

You’re gonna feel small until you earn the right to feel big. It’s gonna feel really dangerous. You’re gonna want to see what’s over that next hill, but if the sun is setting, like, get to shelter. Can’t wait to get back to my ranch and put my cozy fireplace on and wait till morning, you know? We want more of that vibe.

Like golden lacquer to put the piece back together. And the thought was rather than hiding the scars, you make them more beautiful. And the philosophical parts that sort of appealed to me with that is there’s a lot of me and Tim in that, of… We’re so appreciative for our time at Blizzard, but we didn’t come away unscarred. And there’s also a philosophy in Kintsugi that nothing’s ever perfect, and the pursuit of perfection is actually a mistake, and that there’s beauty in imperfection. And so I relate that to myself personally. That’s how I feel in an aspirational way. I’m not saying I’ve achieved it, but in an aspirational way, I want to be that way. And I think it’s also an analogy for the making of games. Like, it’s a…

And so I relate that to myself personally. That’s how I feel in an aspirational way. I’m not saying I’ve achieved it, but in an aspirational way, I want to be that way. And I think it’s also an analogy for the making of games. Like, it’s a…
Jeff Kaplan
Making of games is a constant pursuit of imperfection. A game is never gonna be perfect. Just ask the players. They’re very vocal about it. And seeing the beauty and the imperfections and the strength in something that’s been broken that can be stronger.

Greatest video game of all time
Lex Fridman
You had a heck of a difficult couple years here. And so in some sense, it represents that beauty in imperfection. So everybody listening to this I hope, I hope you do have it out on, on Steam. Go check out Legend of California. Truly a beautiful world. I’m so glad you are actually creating this, low-key, quietly creating this beautiful, incredible world. Ridiculous question, but can we talk about some of the greatest games of all time?

What… I mean, I know this is a bit of a nerding-out kind of thing, and outside of the games you’ve been part of creating, I think Blizzard has created some of the greatest games of all time. Outside of those, what do you think are in the list?

So there’s one that’s the best. It’s Legend of Zelda: Breath of the Wild. And then there’s this list of greatest games: Zork, Ultima,

Every aspect is so thoughtful, so well designed. The art matches the design and the tech, and even integrating with the Switch in the way it does. How do you keep making Zelda better? How can Legend of Zelda: Ocarina of Time exist and somebody make an even better Zelda game? The way you can chop down a tree and float in a river, and, like, the world is a toy and everything works as you wished and hoped it would work. And there’s a narrative aspect to it, and there’s really fun combat and action and itemization. There’s so many things that that game gets right that other games are lucky if they get one of those things right, and are… become best in their genre just for getting that one thing right. And Breath of the Wild does them all right and the best.

Because nobody else creates that. You’re right. Under the pressure of having created a bunch of Zeldas that are, like, really great games, to be able to deliver once again.

And even if my first impression is like, “Wow, they’re doing what weird thing with the controller this time,” and then you get your hands on it and you’re like, “God.” My son and I, we both played Legend of Zelda: Breath of the Wild, and he makes games also. And we had this moment where he’s like, “I’m so sad after I played it.” And he’s like, “I know I’ll never make anything like this.” And it’s that weird, like, you honor it so much and think it’s so great. Red Dead was like that for me. Red Dead Redemption 2 is… that’s a game I put on a shrine. Not just how brilliant the game itself is, but as a game maker, as a craftsperson who makes games, how the hell do you make that? Like, only Rockstar with all the years of making those types of games. No one else can come in entry level-

Yeah. I don’t give anyone a pass. I feel like a lot of gamers and game developers, like, if it has writing, they’re like, “The story’s so good.” I’m like, actually, very few games have great story. But Red Dead has a great story. It’s got great character development. It’s got a good plot. And the dialogue is like… It’s like Tarantino-level- … high-quality dialogue. So… Red Dead’s up there. I have my other games that make the list for me, and these are… Both these games are… I would never tell you to play them. EverQuest and Rust are two of the most defining games to me and my career and my life. And Rust, I would never recommend somebody go and play it. Rust will come calling to you if you are up to play it.

I don’t know yet. Probably every month. We want it to be fast enough that you’re not too attached, but we wanna make it rewarding. Like, the trick is coming up with not why am I upset that the world resets, but why am I excited that the world- … resets? And we know players can get very angry about resetting worlds, but anybody who’s played 5,000 hours of Rust, like some of us, the resetting world is the magic. It’s, “I can’t wait for the next reset because the adventure starts all over again.” And if you wanna play the first time with me—like, if we wanna play World of Warcraft, and I’m level 80 and you’re level one, there’s no meaningful experience we can have together—but in Rust, we just wait for a reset and we’re both naked on the beach, you know, from minute one.

AI and future of video games
Lex Fridman
Yeah. So certain games just capture your heart and they stay with you forever. What do you think is the future of video games? So there’s a lot of conversations about AI helping expand maybe the storytelling aspects, the world creation aspects, becoming a tool that people can use more so. Maybe creating more believable NPCs, that kind of thing. But also there’s, as we’ve talked about, the video game industry is changing and evolving and trying to figure out, well, there’s the indie game makers that will have more power… Or these larger game makers will have more power, so what do you think the future of games looks like?

I think with AI in mind in particular, I think the current state of AI, trying to integrate it into development is mostly a hot mess.

Jeff Kaplan
But I do think that, you know, games are a technology-driven art form. And somebody much smarter than me once described it—and I’m paraphrasing—making a game is like making a movie if you had to invent the camera every time, because you’re kind of inventing the technology of your specific game. And I think AI can play a role in that, and it would be silly not to look at it as an option. The problem with AI right now is it’s overconfident in what it tries to deliver. Like, I fooled around, obviously like everybody, you mess around with, you know, ChatGPT and Gemini and you fool around with some of the art generation, and it’s fun for non-artists to fool around on Midjourney. But it’s mostly weird and shitty.

And even, like, when trying to have AI answer for me… Like, I don’t normally make UI in a game, and so I’m trying to figure out, like, UMG and Unreal Engine and I’m asking ChatGPT how to fix, like, a simple problem, like, how do I make the chat wrap, you know? And it, like, overconfidently gives me the wrong answer. And it’s, like, right one in 10 times. So its hit rate has to be a lot better. I think there’s a lot of moral concerns around AI when it comes to creative pursuits as well, like no one’s creative work should ever be used by AI without their permission.

You know, voice actors and artists, it can’t be lifting from them without their permission. That’s just immoral. It’s no different than just sort of stealing. So that’s wrong. I think how I’m curious, like especially as somebody who runs a small studio with 34 people, it’s like, what are the points of tedium that maybe AI could help out with that I don’t wanna do, and I’m not gonna hire someone to do? So I have, like a really dumb example: I’m making a bunch of images, I size them all incorrectly ’cause I’m dumb and I’m not an artist, and I did it all in Photoshop, and I have like 2,000 images that are the wrong size. I can have ChatGPT resize those and zip it in a file for me, and it literally takes it like a minute to do that.

I wasn’t gonna hire an intern to do it. I was just gonna work an hour later or two hours later that night to do it. Like, it made my life easier. It didn’t take a job. That seems okay. As long as that ethical line stays in place, what I- what I don’t worry about is, no matter how good AI gets, never gonna draw a picture like Arnold Tsang. It’s never gonna tell a story like Chris Metzen. You know, that human spirit is irreplaceable.

Lex Fridman
Yeah, it’s hard to put into words what is that magic that humans produce, but they do. Truly great creative minds, truly great creative teams, they- they create something special. It’s hard to really articulate exactly what’s missing with- with AI, you know, what people call AI slop. ‘Cause it creates really beautiful imagery and beautiful stories, and very believable text. But it’s not quite… It doesn’t have that, I don’t know what it is, the edge that’s human. Maybe it’s the imperfections.

Jeff, formerly from the Overwatch team, I have to say from the bottom of my heart, and I think I speak for millions of people, thank you for everything you’ve created in this world. Now that I’ve gotten the chance to see the new game, I’m, I can’t tell you how excited I am to try it. Thank you for everything you’ve created. Thank you for everything you represent. Thank you for remaining and fighting for us as one of us. So thank you, and thank you for talking today.

Guitar solos
Lex Fridman
I heard somewhere that one of the things that made you fall in love with music was listening to guitar solos, some epic guitar solos. What’s an early guitar solo that you remember you connected to spiritually , musically, where you’re like, “Wow, there’s magic in this”?

Rick Beato
Well, the first solo that I learned was Hey Joe. It was actually a good beginner song, you know, when I first started playing the guitar, because it has pretty simple chords, right? So it’s like E, C, G, D, A. And I learned the solo, and I figured out this, like, I’ll say it’s this pentatonic scale, E minor pentatonic scale though. I didn’t know that’s what it was called, but learned this thing, and it’s like, “Whoa, he’s just in this one shape here.” Now, there was no… You couldn’t go look anything up. You just, if you could figure out the notes, you noticed that there was a little pattern to it.

And then I got so obsessed with it, and I showed my younger brother John, who started playing guitar right at the same time I did. So I was 14, he was 11. And I would play rhythm for him for five minutes while he would solo over Hey Joe. And then as soon as I’d start soloing, he’d throw the guitar down, then we’d get in a fight. And so my mom eventually was like, “What is going on here?” And I was like, “John won’t play rhythm.” “John won’t play rhythm for me.” She’s like, “Okay, I’ll play rhythm for you. What, what are the chords?” And-

We should mention that Hey Joe, and Hendrix in general, is kind of known for the rhythm not being simple rhythm, just the chords that you mentioned. It’s what you do with those chords. It’s almost improvisation, the rhythm side.

I have to throw in something that is so weird that people, you know… Something that a lot of people won’t know, just to have it on there, so I can at least introduce a person. You know, I’ll put somebody like Allan Holdsworth, who’s a famous fusion guitar player. I’ll throw in one of his solos or something—just some, some oddball solo in there, just so that people, as they’re listening down the list, will get exposed to something they would not necessarily get exposed to.

No, I’m not. But I don’t want to say greatest, you know… You can say, well, there are people that inspired Jimi Hendrix. Charlie Christian, older guitar players. Charlie Christian and Django Reinhardt were the first two really big, and probably Andrés Segovia—those were three of the giants of the 20th century, as far as guitar influences for most of the players that were to follow.

Gypsy jazz and Django Reinhardt

So here, going to Perplexity, Django Reinhardt was, of course, a jazz guitarist and composer, active mainly in France, and is widely regarded as one of the greatest guitarists in jazz history.

So, Django was… Well, there’s a huge movement right now, Gypsy Jazz Movement, as they call it- … that is kind of built around this style of music that he played back in the early 20th century. One of the things about Django is that he was in a fire, and he had two of his third and fourth finger, so his ring finger and pinky were essentially melted together. He had no use of them. Although he could use them while he was chording, but a lot of these incredibly fast lines, he’s just playing with two fingers. And it’s amazing.

Bebop jazz
Lex Fridman
It feels so free. And fun like swing, and then at least you said pre-bebop. So bebop was a kind of jazz that was also influential on you in your own life journey. And it’s this complicated, legendary kind of jazz that was very influential on the music that followed. So what, what was bebop?

Rick Beato
Well, after the big bands were happening in the, you know, from the ’20s through the ’40s, people would go out and play in small groups that they would tour with. And Charlie Parker, who’s really kind of the, one of the main figures of early bebop, really developed the language of it. Usually, the music that they’re playing over are standard chord progressions- … that they would use as vehicles to improvise over. A lot of them were AABA form. And Charlie Parker created this language of improvisation that was far more sophisticated than the swing players of the big band era. You know, think of people like Benny Goodman of that era. They would have really fast tempo songs, angular lines, chromaticism, things like that, chromatic notes.

It’s very difficult to do. And hearing it as a kid is one of the things that I think enables you, just like languages, enables you to learn it as opposed to somebody that’s never been exposed to it and tries to learn it as a teenager. So I think it’s very similar to learning languages, which kinda is like my theory on perfect pitch, that every child is born with perfect pitch. And they start to lose the ability around nine months-

… when people become culturally bound listeners, when babies do. They start out as citizens of the world, you know? They have the neural pathways to hear the sounds, the phonemes of all 6,500 languages spoken on Earth. But then around nine months, they begin to lose that ability and they, when they become these culturally bound listeners, there’s a great YouTube video with this woman, Patricia Kuhl. She’s a language researcher. And I watched this, “The Linguistic Genius of Babies.”

They exposed kids to Mandarin three times a week for 25-minute sessions, just a person speaking Mandarin to these babies. And they were able to recognize the sounds, the phonemes of that language even later on. And when I realized that my son Dylan had perfect pitch, I thought, “Why does Dylan have perfect pitch but no one in my family had ever had perfect pitch?” And I thought, “Well, it must be because of the things I exposed to him prenatally and then in the first nine months of his life.” ‘Cause that’s the only way I could explain it.

Perfect pitch vs relative pitch

It’s the ability to identify any note without a reference tone. So you can play, it doesn’t matter how quickly they are, a person with perfect pitch can hear a note and immediately identify it. Or a collection of notes.

Relative pitch is basically learning how to identify pitches relative to a stated tonic or something that you’ve heard, or just relative to each other. If you hear a note and then you hear another note after it, you can recognize, let’s say, it’s a minor third interval. So if you’re on the note A, the next note would be C. So once you’re given a reference note, you can use relative pitch to identify the relative nature from one pitch to another.

Well, my course, it will play you an interval, and then you identify it by clicking on whether it’s, you know, a major third, or minor third, or major sixth, or minor sixth, or perfect fifth, or tritone, whatever it is. And it will teach you gradually, over time, how to recognize all the intervals.

And for learning solos, for example, or learning melodies, being able to sound something out.

They have to be taught together because these terms are really music theory, right? Those intervals: major second, minor second, major third, minor third, perfect fourth. So as you’re doing that, and then you… Once you learn the intervals, the 12 intervals in an octave, then you learn them both melodically and harmonically, so played together and separate.

Yeah. With an eye towards… You learn the chord shapes and you learn how to strum basic patterns to begin with. I think the first thing for learning guitar is actually how to position your fingers so that you don’t mute strings that you don’t want to mute. That’s the hardest thing for people to do, basically, is to get their fingers arched to where they… If you’re playing a C major chord, your index finger’s on the first fret of the B string, and you have to have that open E string ringing there. And it’s hard for people to make those micro-adjustments. You take it for granted, like, you’ve been playing guitar- … for, I don’t know, how many years? Forever, right?

And you don’t even think about stuff like that when you’re playing a guitar solo.

Comfortably Numb is a good example, but if you do lead, you have to get a super clean sound. Now, that’s both when you’re playing fast, you want it to be super precise, but when you play slow, when you have one note, and you’re holding it, and you’re bending it- … it better be really clean.

Yeah, ’cause you’re lifting it with part of a flesh. And of course, you have to decide, depends on how OCD you are, do you wanna be like the perfect, the proper musician? Or do you wanna do a Hendrix? So the thumb over the top.

Way over the top, yes.

Lex Fridman
And so, like, you… I if you have a fretboard here, I think the more, like, classical guitarists, the very proper, perfect perpendicular alignment of the fingertips to the fretboard, versus, like, Hendrix’s, like, “Fuck it. You nerds. I’m gonna do it.” With the messiness is part of the magic. Of course, like B.B. King is also kind of messy looking in terms of his positioning of the fingers, but his tone is incredibly clean.

I think a lot of it has to do with how they wear their guitars. If you wear your guitar low, if you’re Hendrix and you’re wearing your guitar-

That’s true.
That’s true.
Rick Beato
… if you’re wearing it lower, lower, then you can’t get your fingers on top of it like that. And, the thumb acts as a way to mute the lower strings from ringing if you’re playing through a loud amplifier. So there’s so many other micro-adjustments when you’re playing leads, ’cause you have to kind of mute the other strings that are… so they don’t ring out— … if you’re pl- playing the first note in Comfortably Numb and the solo at the end, and you’re at the ninth fret of the G-string, and you bend that- … if you bend that G-string and you accidentally hit the B-string under it- … you don’t want that ringing. So you have to kind of angle your index finger so it-

Rick Beato
Well then, it’s like if you play electric guitar, then you get into single note playing and stuff like that. That’s where it gets, to me, where it gets really fun. You know, you have single note playing with riffs, if you think of Back In Black, right, that has a riff embedded in the actual melody. Or many songs that have riffs, the Hendrix stuff that has chordal riffs, and you’re moving up the neck and involving all the fingers and things like that. So there’s… it really depends on what you wanna, what styles you wanna play.

And then you have finger picking, if you have Stairway to Heaven, songs like that. How ’bout wanting to learn that? That involves finger picking, because you have to isolate certain notes of the chord and play two together, you know, and multiple times.

There’s a few crossroads where you get to select things. So I guess you’re speaking to the fact there’s a… if you’re righty, there’s a right hand that you can use your fingers or you can use a pick. And that’s a choice you make.

And sometimes you use both, ’cause in Stairway to Heaven, you’re using the fingers at the beginning, or fingers and pick, hybrid, they call it hybrid picking, and then later on, you’re using the pick to flat pick the picking patterns.

Yeah, but it usually turns into something longer. But otherwise, like, if you’re a busy life, you know, taking a day off… that day turns into a week, and then a week turns into a month, and all of a sudden you haven’t touched the instrument for months.

Which is why I leave my guitar on a stand all the time, so that if I walk by it, I’m like, “Oh, okay, I’ll just pick it up for a second.” Then that second turns into 10 minutes, and an hour, two hours.

Now, I… just a quick backstory on this. I made this for my friend Shane’s wife who wanted to see… ’cause Shane was a friend that I was producing, and he was there, and Dylan had come down the day, in the day, and I said, “Oh, check this out,” and I played this stuff. He’s like, “That’s amazing. Can you make a video so I can show my wife?” And I was on the way to a school board meeting, ’cause I was on the school board at Dylan’s school- … and I said, “Hey, Dylan, come downstairs. I want to make this video. It’ll take one minute, just need to do this thing for my friend, Shane.” And he’s like, “I don’t want to.” And I said, “Come on, this’ll take one minute.” “I don’t want to.” So I said to my wife, I’m like, “Nia, would you tell Dylan to come downstairs?

So when Dylan was about two, he… I was doing a FaceTime with my brother Jon, and I was like, “Check this out, Jon.” And I played the Stone in Love, Neal Schon’s solo from Journey, and I was like, “Check this out.” And Dylan would sing along and my brother Jon was like, “Wow, Dylan can sing all the notes.” And I was like, “Yeah.” Then I played Black Dog, Zeppelin-

… and Dylan would sing that. And it’s like, “Dylan’s got a good ear.” Then Jon and I were like, “Well, we have good ears, too.” So it was probably… Maybe we could have done that when we were that age. So a couple years, more years goes by. Well, he was about three and a half, and I’m in the car. I was like, “Dylan, sing the Star Wars theme.” And he sings it, and I’m like, “That’s in the right key.” And I checked. I play it on my phone, and I was like, “Oh my gosh.” Then I ask him, “Play… Sing the Superman theme.” Because we’d been listening to John Williams soundtracks the week before, and he sings that. And that was in the right key. And I ask him another song. So I turn the car around, I go back to the studio.

I go to the piano, I hit the note B-flat, and Dylan says, “Star Wars.” Star Wars starts on a big B-flat major chord, but it’s the note B-flat is the main one that you hear. And then I play the note G, and he goes, “Superman.” And that’s the first note in the trumpet part of the- … of the Superman theme. And then I realized that he had perfect pitch, and then in five minutes, I taught him the name of the 12 notes. Which he already knew, but he just didn’t know the names.

Where I play these super complex polychords. Okay, I’m going to do some polychords for you. These are really going to be hard. You ready? What’s this? C augmented over D-flat augmented. Okay, sing a B-flat. Very good. What’s this chord? A-flat major over A major. Great, sing an F-sharp. Excellent. What’s this chord? A minor over D-flat major. Great. What’s this chord? E add9 over F major. Excellent. E add9 over F major. So I had to look at my hand to make sure that that’s what it was- … ’cause they’re all in inversions.

So I think the reason that this went so viral is that the more that someone knew about music, the more that they shared the video. Because these polychords… So the people that were the best musicians looked at it and were like, “Oh my God.” You know, it’s C augmented over D-flat augmented. And the second chord was A-flat major over A major, but they were both in inversion, right? So it was like a first inversion A-flat major chord, first inversion A major chord. And then an A minor over D-flat major, and then E add9 over F major. And for an eight-year-old… I mean, for anyone- … plus they’re all close-voiced. They’re all just right next to each other.

And I would play the Well-Tempered Clavier, and I would play… I have a friend who… Turkish pianist who’s one of the greatest improvisers I’ve ever heard. His name’s Aydan Esen. And I would play Aydan’s improvisations for Dylan. It had very sophisticated harmony and linear things in it. And Keith Jarrett, and mainly jazz, classical, and modern classical music. And then, then we would play, listen to rock music once he was born. I’m talking on my wife’s stomach before Dylan was born- … starting at 15 weeks, for 30 minutes a night.

And this is also another component of saying, “This is where this word stops or starts and stops. These are how the phonemes are separated from one another. These are how they’re connected.” So I believe that all kids are born with perfect pitch and then around nine months they begin to lose it. If you don’t engage their social brain, making these pitches know … I never played pitches for Dylan and said, “This is a C, this is a B-flat-” “… this is a G.” I just played complex-

He’d… we’d put on a record, I’d sit on one side of the room, he’d sit on the other and not say a word. Listen through the whole side A. I’d go flip it over, listen to side B, never say a word. And then get up and go do stuff. And we did that all the time.

And so the first time you impressed your dad was with the Joe Pass song, right? And by the way, we’ll have to go to this song ’cause people must have forgot, right? People just think you’re like a good communicator or something. They don’t realize how good you are at guitar, how good you are at actually a lot of instruments, but guitar especially. And there’s this video, “The greatest guitar solo, period.” Can you give me some context for this particular intricate, complicated solo? Who’s Joe Pass?

Rick Beato
Joe Pass was a guitarist. He lived from 1929 to 1994. And he was one of the greatest bebop players and solo guitar players. So he made a record that this is off of called Virtuoso in 1973 that my dad gave me for Christmas when I was in 10th grade. And he said… And this is not like my dad. My dad worked for the railroad. He was very, you know, few words spoken. Born in 1919. He said, “If you ever learn to play guitar like this, you’ve accomplished something with your life.” And I was like, “What?” So this record stayed… was unopened until about March after Christmas. And one day I was like, “Okay, I’ll open it up.” And I put it on, I start listening to it. And I was like, “Whoa, this is kinda cool.”

If you go back to that Brother to Brother, Gino Vannelli thing with Carlos Rios playing, that stuff is incredibly hard. This, I’m starting, I don’t know any of these chords.

Right, but trying every combination of fingers. I had never played that chord. That’s a weird-looking chord. And, but I kept … I moved my fingers around till I heard where it sounded like, “Oh, that’s it, definitely.” And I just looked at my hands like, “What is that?” Had no idea what it was.

I heard licks like that all over this, so I knew that that was… and then these licks here, he plays a lot of ideas like that. That’s basically a C9 chord in the top notes of it.

Miles Davis

So what was the role of bebop jazz in the history of music? It seems like it was influential in your life. Another guy you had an incredible interview with: Flea. People should go listen to that. Was a great conversation. One of the things that surprised me is just how many musical genres influenced Flea. And the guy showed up in a Miles Davis T-shirt.

Rick Beato
Because he was the greatest innovator in the history of jazz. He was at the forefront of all these different styles of jazz. I mean, he started as a bebop player, and then he had records like the Birth of the Cool, and modal jazz, and hard bop, and records like Bitches Brew, where he started to, I guess you would call it fusion. You start to get these records. You had two main groups of Miles Davis. You had the Miles Davis ’50s quintet and the Miles Davis ’60s quintet.

Now, Miles made records with many people, but the ’50s quintet had John Coltrane in it. Had, I mean, had different piano players—Wynton Kelly—but Paul Chambers on the bass, Philly Joe Jones on the drums. And that particular group made just incredibly important records. And then he had his ’60s group, which was Herbie Hancock on the piano, Ron Carter on the bass, Tony Williams on the drums, and Wayne Shorter on the saxophone. And they made all these incredibly important records.

I forget who said it in an interview with you, but they talked about like Miles Davis, his music feeling like I think toes hanging over the cliff or something like this. Meaning, like, there’s always a risk, there’s a danger that you’re willing to make, to fuck it all up live. And that feeling is what creates the aliveness of the music. Like, can you speak to that? Just the creating in the music, the feeling like you’re on the edge. Like, you’re challenging the possibilities of what can happen, and it all can go to shit, and because of that, it feels alive.

Well, when I interviewed Ron Carter that played in Miles’s ’60s quintet, I asked Ron, ’cause Ron played bass on 2,200 recordings, famous records. And I said, “Did you guys ever rehearse with Miles?” “No, never.” I said, “So, what would you do?” He goes, “We’d just show up at the studio, and he’d have the charts, put them on the stand and we would just roll.”

And I said, “Would you listen to it after?” “No.” And I said, “Well, what about the live records that you did, when you’d record at clubs and things like that?” He goes, “We never knew that we were recording.” He goes, “Maybe I’d see a microphone, a different kind of microphone in my bass amp.” He goes, “Then months later, a record would come out and I’d see it, and I was on it, and I would take it down to the union and say, ‘I played on this record,’ so you get paid for it.” But he said, “We didn’t even know we were recording.” So Miles was always about, you know, don’t think about it, just play.

So his stepfather was a jazz bass player. And his… When his parents got divorced, he was born in Australia, and then they moved to New York. Then his parents got divorced, and his mom married his stepfather, who was a jazz musician. And they used to have jam sessions at their place, and Flea loved it. It was kind of like my upbringing with my dad, playing jazz all the time. Once it gets inside you, it’s just there. And so he is heavily influenced by jazz musicians.

… because as much as I love to play the guitar, and I love to play the guitar more than anything, I think, but the bass really defines what the quality of the chord is. ‘Cause you can put the root in there. You can put the third of the chord in the bass. You can put the fifth in there. You can play a lot of notes. And whatever you play in the bass kinda defines what kind of chord it is. So, the bass player has a lot of power.

On that day. Right. Now the day later, I would have said, “It’s the second solo.” But I did the first solo because nobody talks about that solo. And that solo is equally great. And when David Gilmour… When I played it for him, and we talked about it in my interview with him, it was… Just to watch his face when he listened to it was incredible. I mean, I’m thinking to myself, it’s like, I’m sitting with David Gilmour, and he’s listening to Comfortably Numb. And he’s hearing it. He’s played it a million times live, but how many times has he gone back and listened to it on the record? Probably not for a long time. And then he’s hearing it, and he’s like, “Ooh.”

He has just an incredible melodic sense. He knows how phrases should be put together. There’s a flow to his ideas that I think is just incredible. It’s the same with Hendrix. This flow, how one idea leads to the next, how there’s space between them. It’s just like speaking.

That’s what I read about Miles Davis is, he’s very good at understanding tempo and the value of silence. And I think David Gilmour doesn’t always play fast. But he does a lot with less. And then some of that is also on the more technical side, probably the tone of the… I mean, he has one of the most uniquely recognizable tones in all of music. What do you understand about what it takes to shape the tone that is David Gilmour?

But there I am, sitting there right next to all these pedals that… And I asked his tech, Phil, I said, “These are the same ones you used on the records?” He’s like, “Yeah.” His tech has been with him for, like, 50 years. And I mean, the exact ones? Yes. It’s just, it’s hard to… It’s hard to imagine that those things still… Of course, though. He’s just kept it. Yeah, this is his Binson Echorec that he played through, and this is this. You know, these are all the same effects pedals. And the… Wait, is this the same Hiwatt amp? Yeah. Is this the same… Yes. Yeah, you get some new stuff. But they keep all their own gear, and that’s… I mean, he does sell his guitars for charity.

Well, of course, they converge towards that kind of hardware. But there’s so many tiny details over the years. You see the final result of it, but there’s a, there’s a journey there, of exploring. And of course, he’s not… I guess he’s not doing any soft… Like, no emulation, no amp?

There’s a little rack thing that I had heard that he used, but I asked him for sure. It’s called the Zoom 9030. I put out a short where he talks about it. I said, “So, that Zoom 9030, is that a real thing?” ‘Cause I’ve read about it. He’s like, “Yeah.” And he talks about how, when he’s sitting there recording on his own… And he runs Pro Tools himself, and so he’ll be sitting there. There’s no one there to help him. He’s like, “I’ll just plug into this thing, and then I’ll play a solo with this model.” It’s like a kind of ’90s modeling, early modeling thing.

And he’ll play a solo, and then after a while, you hear the solo, and it’s like, “Well, I’m not gonna replay that. That sounds great.” You get used to the sound of it, and that’s what it is. So people always talked about, “Oh, well, he couldn’t have used that. He’s recording through an amp,” and… ‘Cause it sounds great. And then he’s like, “Yeah, yeah, so that’s what I use.” And then I have the video of it right there, and it says his presets, DG1 and DG2 and, you know, whatever.

Yeah.
Yeah.
Rick Beato
So, but I do make a playlist of songs that I wanna talk about. So, that kind of guides me… ‘Cause I wanna make sure that I… There’s specific things that I need to play to, so that you can jog his memory. ‘Cause anytime you play something that somebody recorded, even 50 years ago, they’ll remember. If they don’t remember the exact specifics, that brings it to life to them again. And they can kind of piece together some aspects about it, and they can really talk. He can talk about the phrasing and the, you know, the kind of melodic direction of things like that.

So, there’s a lot of tiny details that go into a particular song, whether it’s in the production or how it’s played or how it was composed, all that kind of stuff. And you don’t know what those are ahead of time.

You just know the song, and you just are looking to jog their memory, and maybe your own curiosity of like, “How did you do this?” Or, “How do, what, this sound or that?” You make it look easy, but you have to have a depth of knowledge. You’re saying you don’t prepare.

Lex Fridman
Exactly.
Exactly.
Rick Beato
That’s what it is. It’s that I can remember when records came out, who produced them, where they recorded them, who was the engineer, what songs are on it. And not only that, but the people I’m interviewing know that I can play all the parts- … of all the instruments, ’cause I’ve done breakdowns of their songs, which is why I get the interviews with them in the first place, really.

I will say this, Lex, is that the other thing is that most of these people have a really good sense of humor. When I was, when… The first time I interviewed David in New York, my brother John came along, and he is a massive David Gilmour fan. That’s his biggest influence as a guitar player. And so he said, “You’re interviewing David Gilmour? Oh, I’m coming.” I was like, “All right. Come on. Come on down.” So my brother John’s standing about five feet away. And John is a sales guy, but he… Great guitar player. So John’s like… I was like, “This is David, this is my brother, John.” “David, great to meet you, buddy.” And you know, it sounds like it’s so… He’s a sales guy. And so during the interview, I said, I was like, “Hey, John, what was I gonna ask David?”

Rick Beato
Oh, ask him about the Gilmour effect.” “Oh, yeah, that’s right.” And the Gilmour effect is my thing that I say in the comments section when people say… Anytime anybody plays anything technical, “Oh, yeah, that’s great, but I much prefer David Gilmour.” And so I always call it the Gilmour effect. Anytime I have, like, Yngwie Malmsteen- Anybody that played, that has chops that I- … interview, the, the, the negative comments are always, “Well, I prefer David Gilmour.”

It’s the first guitar solo I ever learned, so I had to put it on there. So, I don’t necessarily do these by… I do those in kind of how important they are to me and my development. So, there’s always a biographical component to these lists. Number three was Kid Charlemagne, a Steely Dan solo, Larry Carlton. Amazing solo, extremely difficult to figure out.

Rick Beato
Probably, there’s two solos on the list that are just about, are very… That one I can play. But there’s a few solos that are very hard to play. Stone in Love by Journey, by Neal Schon, is very hard to play some licks. There’s a song… There’s a solo by a guitarist, Carlos Rios, that people don’t know. It’s Brother to Brother, a Gino Vannelli song, but it’s very hard to play and figure out. And that people don’t know the solos. I put it on my list ’cause I knew that a lot of people were gonna watch it and they’re gonna know what this solo is.

Lex Fridman
For me, the sentimental one, my first solo is Mr. Crowley, Randy Rhoads. I like the musicality of Mr. Crowley, that there is a melodic component to it. You’re playing really fast, but there’s a melody to it. And also, there’s like a legendary nature to the brief time we had Randy Rhoads.

Now, I had it high on the list, and I’ll tell you why. I would’ve had it lower ’cause it’s one of the early ones, ’cause I wanted people to be like, “Okay, oh, this is a serious list.” So Rick’s gonna talk about serious stuff. So- And Rick’s gonna play along with all these things. So I wanted to kind of state that at the beginning of the video. I mean, I made the video in one day to do 20 solos. I think I played 19 of them, but the Heart solo that I had on there- … Nancy Wilson, I played the video of. And I tried to get a couple of my friends to play the Ice Cream Man, Van Halen solo.

Rick Beato
So I called Dweezil Zappa, and I was like, “Dweezil, can you play the Ice Cream Man solo? I’m making a video about it.” He’s like, “Oh, I’d have to practice that.” Then I called my friend Phil X who’s an amazing guitar player, and he’s like, “No, I’d have to practice that.” I was like, “Come on, man, can’t let me play Ice Cream Man?” The opening lick of Ice Cream Man that he plays is very hard to play ’cause it’s an incredibly long stretch. And it hurt my fingers to do, and Eddie would turn his guitar up like this to play. And plus, it’s a tricky… It just… It’s a tricky rhythm, and it’s such a big stretch. It’s like, “Man, I can’t… That hurts my hand.”

But to me, I mean, there really is nobody like Mark Knopfler. I mean, his is unique guitars. There’s something about his tone. Speaking of Gilmour, there’s just the tone, the care, the timing of the notes.

Yeah. There’s certain songs like Europa by Santana, Santana can have that tone too. That Mark Knopfler makes me real- just how clean it is. I think he beats B.B. King in my book in terms of the cleanness of just pure beauty of a single note. It’s like the power of a single note. I don’t know anybody who beats Mark Knopfler.

When I hear Brian May, I can immediately recognize it’s Brian May. Incredibly melodic, the tone that he has. Gilmour, Hendrix, everyone that we’re talking about, Van Halen. It’s just, they have that one note. It’s like, “Oh, I know who that is.” And that’s why we’re talking about him.

I guarantee you. So I was gonna do a video last week where I was gonna play songs in reverse, okay? See if you can recognize these songs in reverse. And I had my two assistants come in. It’s like, “Do you know what song that is?” They’re like, “Oh, that’s Adele.” Like, “What?” Then they’re like, “Oh, that’s, that’s Nirvana.” Instantly, they could recognize. Like, “Well, that’s not worth me.” It’s like, yeah, it’s so obvious. You hear the tone of the voice backwards, forwards, it doesn’t matter. You know who it is.

And I, as I was listening to it, just doing a whole personal journey introspection, knowing that I’m gonna talk to Rick Beato, listening to just a bunch of songs, and I learned—it’s embarrassing that I didn’t know the stories behind the music—but I learned that Eric Clapton was married for a decade to the same woman that George Harrison was married to. And that this woman was the muse, the inspiration for like so many of the legendary songs of rock- … including Wonderful Tonight, including Layla- … and including George Harrison’s Something. Legendary song also. The same woman. Is she the greatest muse in rock history?

This is great. So in your interviews of musicians and producers, I think the thing you’re ultimately fascinated by is the process, the recording, the production, the songwriting, the different elements of the process. So are there examples of different things that stand out to you from all the interviews you’ve done? And by the way, all the recording and production you’ve done yourself. So on the recording front, on the production front, on the songwriting process front, just things that pop into memory.

When I’ve interviewed the guys that are the producers, like Rick Rubin, Daniel Lanois, Brendan O’Brien, Butch Vig, the thing about producers, as opposed to people that are musicians—if you’re a musician, even if you’re David Gilmour, you do a record, and then you tour, and then you do another record, maybe years go by, but producers are working on multiple records, sometimes at a time. Rick Rubin could be working on multiple records, and the variety of things that they do, you can talk to. I mean, I can talk to Rick about the Chili Peppers. I can talk to him about Johnny Cash.

I mean, these interviews could go on for days with Rick, and the variety of records that he worked on. And there’s so much knowledge to be gained, for me at least, and I think that the craft of production and recording engineering is something that is not well-documented. Especially since there are so few studios nowadays, where there used to be a mentorship thing, where you’d go and you’d work as an assistant engineer.

And there’s so much knowledge to be gained, for me at least, and I think that the craft of production and recording engineering is something that is not well-documented. Especially since there are so few studios nowadays, where there used to be a mentorship thing, where you’d go and you’d work as an assistant engineer.
Rick Beato
And you’d work your way up. I interviewed a guy named Ken Scott that worked with the Beatles. I interviewed him at Abbey Road Studios, it’s just two months ago, and he started as a tape op when he was 16. He started on the A Hard Day’s Night record with the Beatles, and he worked his way up, and he said the first time he ever recorded an orchestra was he recorded I Am the Walrus, the orchestra part.

He set up the mics, and I asked him, I said, “So where was the band?” “Standing right behind me.” The Beatles, right behind him. The guy I’m interviewing at Abbey Road recorded I Am the Walrus there. I mean, he recorded many Beatles songs, and he was 18 years old, and the … I mean, I just can’t, I can’t even fathom that. We … They have a little cafe in the basement of Abbey Road, and I said, “Did the Beatles come in here?” He goes, “Oh, yeah, they come in here and get coffee,” and I remember when they got two microwaves that were like the first microwaves in 1965, and they were amazed by them, and it’s hard to imagine that I’m talking to people that worked on these historic records.

But, you know, they all start with a blank tape or an empty hard drive, and then, you’ve eventually filled them up with this music that you can’t, you can never imagine it not existing, like Stairway to Heaven, or whatever it is.

Lex Fridman
Yeah. It’s funny, like, looking back, even probably for them, just to realize they’ve created that magic is hard to believe. ‘Cause you’re looking at a blank thing and then magic comes out, and you don’t even understand. You don’t understand, probably a lot of these artists don’t understand where that came from. They’re channeling some deeper thing.

When I interviewed Brian May, he told me, I can’t even remember if this was, if we talked about it on camera or not, but we talked about Bohemian Rhapsody, and at the very end… There was a thing where he was depressing his whammy bar a little bit, and it sounds like the piano is out of tune. I never noticed it before. He mentioned this to me. And he said it always bothered him. And there’s always something about these songs that bothers people. Even these songs that he-

Lex Fridman
I mean, that, that … there’s certain moments in songs that are just unlike anything else. In Bohemian Rhapsody when Freddie Mercury is, “Sometimes wish I’d never been born at all…” And then the guitar comes in. I mean, there’s just nothing like that. That was … That … I don’t even know. I mean, that, that whole thing, you’ve done videos on it. It’s an incredibly complicated composition. It’s, it’s crazy that a popular rock song could be this operatic, so complicated. The other thing akin to that moment is Phil Collins with In the Air Tonight, the drum bridge. Do do do do do do do do.

Lex Fridman
Yeah. What is that? I don’t understand how you can create that. What is that? Why is that so magical? Why is that so singular inside a particular song and in rock history period? Like, these moments, I don’t know, musically, I don’t understand how you create them ’cause it might be bigger than musical. It might be cultural, a bunch of different elements, and plus, it’s him filled with … Like, I’ve seen live performances. He has, like, a headset. He does something. He’s like a telemarketer or something. Like, his whole vibe and look to him, he doesn’t look like a rockstar, but he is.

Those are hooks when you think about it, right? It’s like, it’s as much of a hook as any, as the chorus of the song or any song. That drum thing is something that people wait for, and they air drum to it. Everybody air drums to it, and it is a hook, and those are hard to create. Those are … Those moments are really hard to create, and usually they’re done by accident.

Yes, it’s hard. If you chase it, you’re not gonna get it. In your conversation with Sting, he said something about how modern music is simpler more minimalistic, and, ” The bridge is gone,” I think- … he said. And he said he thought that, “The bridge is therapy.” It’s, like, a chance for you to reflect, I guess, on the verse- … before the chorus comes in.

Lennon used to… He would have some kind of biting lyrics, like “We Can Work It Out.” So McCartney writes the, you know, “Try to see it my way. Do I have to keep on going until I can’t go on?” And then, but the bridge is very Lennon. “Life is very short, and there’s no time. For fussing and fighting, my friend. I have always thought that it’s a crime, so I’ll ask you once again.” I mean, it’s very, you know, very Lennon-esque. This is … That was really a … kind of a real collaboration between the two of those.

This is where different parts of the band can clash- … in interesting ways. I mean, the Beatles are the epitome of that. Such … Like, each individual Beatle is a great talent in their own right.

Rick Beato
Because PA systems were so bad back then- … and the Beatles … People screamed so loudly that the Beatles thought, “Okay. We don’t, we don’t need … We can’t tour anymore ’cause we can’t even hear ourselves, so we’re just gonna be a studio band.” And maybe because of … We have all these great late Beatles records, they’re from 1966 on, just because they had bad PA systems. And they had no monitors. You know, they’re in Shea Stadium.

People are screaming so loudly they can’t hear themselves. They’re like, “Okay, forget this. We can’t tour. We’ll just make studio records,” so that’s what they did, and in that one year, like, from August 6th, 1965, they put out Help!. Then in December 3rd, they put out Rubber Soul of ’65. Then, then August 5th, they put out Revolver. So within 365 days, they put out three 14, I think, 14-song records. So they wrote and recorded three incredibly important records. They were in the studio. It’s like working out.

They’re practicing their craft every day, writing songs, trying to outdo the other ones, and so you had the, the perfect thing of, of four supremely talented musicians, songwriters, singers, and then the best producer you could possibly have, George Martin, and, and it was just a perfect storm. I think that when I would talk to friends that would just play in local clubs, and they’d play four-hour sets five nights a week, and they never lost their voices because they’re always working those muscles. And same with the Beatles. They were always in the studio singing every single day, doing takes, and I think that that was part of it, at least.

But you also have this theory- that you know, that the greatest productivity that musicians have is before they turn 30. The greatest, sort of, creative genius that can come out of the human mind musically is before the age of 30.

So, they have a whole lifetime of experience that lead up to this, and there’s not… They’re not improvising, but things for improvising, writing pop songs, and that… I think when your mind is really most active and your brain processing speed is at its pinnacle, that… This is just my theory-

I think about this a lot. If you go back and you watch videos, The Beatles, any of their movies, they’re smoking all the time. The Get Back documentary, they’re smoking constantly. Go watch any of the MTV Unpluggeds, Nirvana, Kurt Cobain is smoking every second that he’s not playing, he’s smoking. Every singer smoked. Every musician smoked. Nowadays, I asked my son, Dylan, “Dylan, does anybody smoke?” at his high school. He’s like- …”Smoke? Nobody smokes.” The- it was an absurd question. And that was part of culture.

You have to be able to control the rollercoaster of your mind, and of course drugs will be a part of that. And you think everything is allowed and everything is possible. And then there’s also culture, depending on who you hang out with, that certain kinds of categories of drugs are good for your creativity.

But, you know, it does seem to go hand-in-hand. And some of it has to do with the period, with the time period, with the place, ’cause sometimes it’s part of the culture. The drug is like you’re saying, smoking. If you were smoking now, that’s gonna be a very different experience than smoking 10 years ago, 20 years ago, 50 years ago. There’s a different vibe. So, sometimes the drug is a deep integrated part of the culture versus an actual chemical substance. The ’60s, right? I don’t know. They were on everything in the ’60s.

Yeah, ’cause he was recording in a studio in Atlanta that I was working with a band that I was producing. And he was in—I was in Studio B, he was in Studio A. And this band that I was working with, they were called Jump, Little Children. And so, he had his assistant come in and ask, “Hey, is this… Are you guys Jump, Little Children?” “Yeah, yeah, yeah.” And then all of a sudden, I couldn’t see out into the live room. Elton walked into the thing, and we were getting ready to track, and I’m, I’m pressing the button. “Yo, where are, where are you guys? What’s up? I thought we were gonna start this.” And no one’s responding. I can hear talking, it’s like, “What, what is going on? Where are they?” Then all of a sudden they come back in the studio and they were stunned.

I said, “Where were you guys?” “Elton John just walked into our session. And he said he’s a big fan. He said to come over when we’re done and hang out in Studio A.” So we did, and he was there with Bernie Taupin, and they were working on a song. And we talked there for an hour, and he was talking about recording two records a year, and then they’d go on tour, and they’d write and record the whole record in two weeks. So Bernie would give him lyrics. Elton would go out and spend 15 minutes writing all the melody. He’d look at his lyrics, and he was doing that that day. Bernie was there, and they had a lyric sheet up on the piano. And Elton would go on, and they’d just re-… “Okay, just record this.” And Elton would sit there and play and come up with the song- … in 15 minutes or so.

There’s a great version of, I think, Tiny Dancer, where Elton is coming up with it on, it’s on YouTube. And he’s just coming up with the music right there. And then the band, “Okay, here’s how it goes.” And they record it right then. Then move onto the next song. I see this. I mean, it’s really incredible. That’s it. Yeah. True. There’s one there that I’ve sort of done the other day with Tiny Dancer, which is about Bernie’s girlfriend. So I just sort of ran it through and then put two verses together, then a mid-like, then a chorus, and then back to the sort of verse sort of thing. It’s, it happens very quickly. It sounds long, but it sort of starts off- << Blue jean baby, LA lady, seamstress for the band. Pirates man, pretty eye, you marry >>

So I just sort of ran it through and then put two verses together, then a mid-like, then a chorus, and then back to the sort of verse sort of thing. It’s, it happens very quickly. It sounds long, but it sort of starts off- << Blue jean baby, LA lady, seamstress for the band. Pirates man, pretty eye, you marry >>
Lex Fridman
Okay.
Okay.
Rick Beato
I mean, it’s really amazing that he just-
I mean, it’s really amazing that he just-
Lex Fridman
Yeah. He’s looking at just the lyrics.
Yeah. He’s looking at just the lyrics.
Rick Beato
Yeah, and it’s one of the, he’s one of the very few people that has the lyrics first and writes the music to it, which to me is far more difficult. 99% Of songwriters write the music first, and then they put the melody and lyrics to the finished backing track.

And maybe they write, like, lyrics, they write, like nonsense words kind of- … thing. And then they figure out from there. Yeah, that’s… I mean, I don’t know what skill that is exactly, but that’s incredible. I mean, in that process he makes it his own. Okay. You had an amazing interview with Kirk Hammett. I’m a huge Metallica fan.

Metallica
Rick Beato
Same here.
Same here.
Lex Fridman
There is a lot of interesting stuff that came out of that, from that conversation. One is the distinction between heavy metal and hard rock. Which is very interesting. Of course, Metallica went through their own evolution. They had many periods. I mean, they’ve been around 40 years.

The other thing is the downpicking, which was interesting, which is creating that really distinct sound.

Rick Beato
James and Kirk’s, the downpicking, I used to be able to do that. I just can’t do that anymore. It hurts my thumb- … to do it. I think honestly, I thought a lot about it. It’s like, why does it, why is it so painful? Why is it so hard? It’s from swiping with your thumb on phones. And I think it affects that basal joint there, and—I’m sorry—no, I’m serious.

I love your theories.
I love your theories.
Rick Beato
Well, I think that that’s actually right, ’cause I’m thinking like, “Why does that hurt so much to do that? All the downstrokes and stuff.” It’s gotta be something. It’s like, yeah, it’s from swiping with the phone.

Lex Fridman
The other thing that came through is that he’s an improviser at heart. And that, I think, clashes with this kind of rigid structure that metal is. So there’s a real soulful, melodic aspect to him. And he gave a lot of props to James Hetfield for just being a great composer, being a great musician and writer of riffs, of rhythm.

Rick Beato
The improvisation part of it you don’t think of ’cause they’ve… ’cause you have the finished songs that you listen to. But those songs are born out of improvisations, of jams, of little fragments of ideas. And then they craft them into these masterpieces.

Lex Fridman
It’s like, it’s one of the ways you can find uniqueness of sound, is by trying different things that are not… I mean, I guess Apple was really good at this, right? Like, completely breaking out of what you’re supposed to do, the ways you’re supposed to do them, and doing it completely differently. You often ask musicians what their perfect song is. First of all, that’s an interesting question.

Rick Beato
I was surprised by that too, but I thought it was like, “Yeah, okay, that’s a perfect song for sure.” The first interview I ever did was with Peter Frampton in 2018, and I asked him in that interview, “What’s the perfect song?” And he said, “Whiter Shade of Pale.” And I was like, “Ooh, that’s a great song.” And then I thought, “I’m gonna ask that to people, just to see what they…” Now people are prepared if I ask that.

But it’s like, they’re willing to go out on a limb and say it. Like, if you ask me, I don’t even know. I guess you just say it, whatever, right? Like, what would I even say? What’s a perfect song? Yeah, I would go… See, I feel the pressure.

Rick Beato
Right?
Right?
Lex Fridman
Because the problem is, the reality is, it changes day by day, like minute by minute. I… Yeah, I would probably, I’m sorry, but I would have to go Mark Knopfler. And I would probably go… Is it really cheesy to say the obvious thing? I would go Sultans of Swing. Even though like I’m tempted to say Europa, but then like…

Rick Beato
Sultans of Swing hits on so many levels- … ’cause it’s got a great melody, great lyrics, and then multiple great guitar solos. And has such a unique sound to it. The other thing is that it sounds very different from other Dire Straits songs. I mean, this is like early- … Dire Straits Strat tone. And then you think of like Money for Nothing is a Les Paul, and it’s a totally different kind of vibe than him playing it on Sultans of Swing. But that song’s amazing.

Tom Waits
Lex Fridman
So it’s like there’s a meta aspect to it. But then there’s also like, we’re talking about this guitar stuff, but Leonard Cohen, Hallelujah. I mean, Leonard Cohen in general. Like these songwriters, they go super simple on guitar. And there, it’s just what’s that called? Singer-songwriter type. I told you off my one of my, maybe the music guest that’s a dream guest is Tom Waits. I’ve wanted to talk to Tom Waits for a very long time, and I’ve gone through different periods of… You’ve met me at a point in my life where I’ve given up on it a little bit. And I was trying-

I’m such a fan of, like the Zappa-like artistry on the musical front, which Tom Waits has, but I’m a sucker for great lyrics. Lyrics to me is such a big part of great songs. And he’s another example. He has a song called Martha. It’s about a love story that didn’t work out, and it’s an older man calling the woman that he was in love with, and basically reminiscing about like, you know, thinking about like, “What would’ve happened if it worked out?” That kinda thing. And then, you know, I loved that song for a long time, and you know at some point I found out that he wrote that when he was in his early 20s. And you realize, it’s similar with the Beatles, like- … These guys somehow were able to capture the human condition so masterfully, and they’re kids.

You asked him an interesting question about how he creates this melancholy feeling that permeates a lot of his songs, and he jokingly said that the secret is all about the seventh and the ninth. So like, musically, chord-wise, what do you think about that? You think he’s onto something?

Rick Beato
He’s talking a little music theory there. Seventh and ninth over the chord that he’s playing. So if you’re playing a C chord, he’s singing a B, would be the seventh, D would be the ninth. And he does use a lot of those notes. But almost all these people that we’re talking… No, all these people that we’re talking about use these notes, and this is why their songs… And when I interviewed Sting, I called them surprise tones, and Sting’s like, “I like the way you use the word surprise.” Notes that are outside the chord that are dissonant with the chords that they’re playing, but then that creates emotion. Dissonance equals emotion. And that’s what I like. I want music to be… to depress me.

Lex Fridman
Yeah. What is that? I don’t know. But melancholy, and I think you articulate it in Aries, it’s not actually that depressing. There’s something about that melancholy feeling that is somehow the other side of the coin of happiness. It’s a kind of longing.

Or there’s a hopefulness to it. That aloneness that you feel. I mean, that’s actually like one of the intimate connections you have with music, is when you’re alone. There’s nothing like you’re alone in a car driving, listening to, like, whatever it is, Bruce Springsteen. Well, I think Louis CK has a bit about that. And was it Bruce Springsteen? But sometimes he has to pull over to the side of the road and just weep, or something like this. It’s just there’s something about that. Sometimes a song just connects with you. And I don’t know, nothing like a melancholy song could do that. It…

There’s somewhere I’ve seen statements like that. That’s a ridiculously inaccurate statement. So it’s a free concert, so any official counts don’t count. It’s definitely over a million. It’s very likely to be 1.5, 1.6 million people. And this moment in history that I think they channeled, it’s like whenever great music… Metallica was firing on all cylinders at the very top of their game, and they meet this moment in history and this place in history.

… Gary Oldman. Just a really… it’s a masterful celebration of Beethoven in an interesting kind of way through the perspective of a love letter that he’s written. But then I realized like… and this is early, this is many, many… this is a couple decades ago now, that, you know, he went deaf before he even started writing the Ninth Symphony, which is why they consider it to be one of the greatest compositions of all time, the greatest symphonies of all time. He went deaf, couldn’t hear anything before he even started writing it. And so there’s that famous story of him in that world premiere of having to be turned around because he can’t hear people applauding, so he has to be turned around to see that people are actually clapping. I mean, there’s just this whole tragic element.

Plus, the meaning of the symphony that ends in this beautiful Ode to Joy, the symphony itself is a kind of… It starts with the chaos and conflict and ends with this celebration of peace and brotherly unity and a— I guess a call for that, a reaching for that, for that peace. And it’s a… and there’s a tragic element to it, again, connected to history, which is it was post Napoleonic Wars-

And it’s a… and there’s a tragic element to it, again, connected to history, which is it was post Napoleonic Wars-
Lex Fridman
… and before the American Civil War. So like, you’re in this, in this middle… this respite from war, calling for peace, not knowing that truly horrific wars are coming. So you have the American Civil War, and you have the, of course, the two World Wars coming. So this, all of it together, and the fact that he’s conducting deaf, and he wrote this whole thing deaf. I was reading a lot about his process, and he just edits and edits and edits and edits. So the fact that he had to edit in his head is just insane.

I mean, it… Beethoven was sick all the time too. I mean, a lot of people were sick all the time. It was very common. What would motivate you to write music, this beautiful music that you can never actually hear except for in your head?
I mean, it… Beethoven was sick all the time too. I mean, a lot of people were sick all the time. It was very common. What would motivate you to write music, this beautiful music that you can never actually hear except for in your head?
Rick Beato
Right? Like, why… The amount of time it takes to write a 35-minute, 40-minute piece, all the parts, you got to hear all the orchestration in your head. You’re editing, you’re doing all these things. Where do you get the motivation when you can’t hear the actual finished work? One, and people would say, “Well, he hears in his head.” But what kind of enjoyment is it? You wanna hear the orchestra… I mean, it’s really profound that he was inspired to do this. There’s a thing called the Heiligenstadt Testament that he wrote. It was a letter to his brothers from 1802. I think they found it in his desk after Beethoven died, and he felt a sense of shame and humiliation because of his hearing loss.

And he said that he was afflicted with this thing where him of all people, that someone standing next to him could hear a flute that he could not hear, or a shepherd singing in the field that… And he could not hear this. And of all the people, why him? Where hearing played such an important part. Another person that would have had to have had perfect pitch, ’cause you could never do this- … if you didn’t have perfect pitch, which I think all of these great composers, for the most part. Brahms didn’t, from what I know, but all the rest of them, for sure, had perfect pitch. So they could hear these things in their head, and that’s how they composed.

But also, there’s, what is, what is that, that he’s able to write like one of the greatest symphonies ever, while deaf? So there’s something about that. We mentioned darkness, but torment that he’s going through. And ultimately, Ode to Joy. Like, not a cynical thing- … but a call for the positive.

And plus, Napoleon broke his heart, because he was a supporter of Napoleon- … because Napoleon was supposed to represent the French Revolution, this, this hopeful future of no more kings, no more monarchs, no more authoritarian regimes. And Napoleon ended up becoming, essentially, king. Becoming an authoritarian. And Beethoven sort of famously was critical of that. Nevertheless, I think maintained a fascination with Napoleon throughout his life. But sort of a kind of more sophisticated, complex view of human nature and human civilization. So becoming more cynical. Like, seeing more clearly that the world disappoints you, that dreams get shattered. And through that, is able to still do this call for the hopeful future. All right, so okay. So Beethoven, one of the greats, for sure.

Every day. People talk about how Bach was not known other than in the places he lived. Eisenach, he was born in. Leipzig, he spent many years. But Bach was known to great musicians. It was difficult to find manuscripts, but there was a premiere of the Saint Matthew Passion that Mendelssohn had done in 1829. It was on March 11th, I believe. He had a manuscript because his father and mother collected manuscripts.

And he got a manuscript of this piece, and he, I think he was 20 years old, and they had a performance of it in Berlin…. and Beethoven, Mozart. They studied the Well-Tempered Clavier, the two books of the Well-Tempered Clavier. But Bach wrote profoundly beautiful music, and some of the most complex contrapuntal music that I don’t think anyone has ever done like that. Extremely bright guy. Had 20 kids, only 10 survived till adulthood. Lost both his parents when he was nine, within nine months of each other. Went to live with an older brother.

AI in music
Lex Fridman
All right. We have to talk about this a little bit. You made a bunch of videos about it. There was a, there was a moment in time, it still goes on, but there was a moment where really people were freaking out about the use of AI in music. So there’s these, I would say, incredible apps like Suno, Udio. ElevenLabs Music is also great. They can generate basically text to song, full song from a text prompt. And a lot of people started freaking out just based on how good it is.

And so you start to immediately imagine how this is going to transform music, and you’re going to replace musicians and all that kind of stuff. It is legitimately nerve-wracking because these are early versions, so you don’t know where it goes. But in your intuition now, you’ve been thinking about this, you made a bunch of videos. Now, like, being able to reflect, “Okay, everybody chill. Calm down.”

So if you write a prompt in Suno and it spits out a song, which I’ve done, made a bunch of videos on this. I made up a fake artist, Eli Mercer, in this video. Then I did a thing for CBS News; I made up this fake artist, Sadie Winters, and came up with this song, “Walking Away.” Well, the computer, the program came up with it.

Then I went to, then I went to Claude and I wrote the lyrics, ’cause Claude’s way better at lyrics- … than Suno is. Suno’s bad at lyrics, at least right now. So I did, I created the lyrics in Claude and then I imported the lyrics into Suno, and I had great results with the songs that it came up with. I always have to qualify that. But then I started thinking about this. People freak out about this, “Oh, this is bad, this is bad.” And then I thought, I was like, “No, who are going to be the ones that are gonna benefit from AI?” Well, the people that are already great songwriters, because you have to be able to recognize when it spits out something good versus when it spits out something that’s not that good.

And there’s a thing that’s happening where people’s ear very quickly is becoming attuned to AI slop. And that’s actually quite fascinating. Like, for example, one of the things, there’s this viral clip going around of an AI-based, like, a soul jazz remix of songs like 50 Cent’s “Many Men,” and I think it is super impressive. And there’s a different pipeline actually. It’s a tricky pipeline to how to pull that off, and I think a lot of the creativity in that, even that kind of remixing, is in the pipeline of how you actually do that, because there’s actually a lot of manual stuff in that pipeline. But I think ironically it’s very cool at first, but when you listen to it for a while you understand that this is AI slop.

For a soul remix, it actually lacks soul. But it made me think of, like, when I listen to soul or blues, I think I really want, in that case, to know… I don’t want an AI B.B. King, I want the real B.B. King. And if I know if any AI is involved in the B.B. King process, I’m tuning out. And I don’t think I’m being a curmudgeonly old dude in that. I think we humans want authenticity.

So when AI, when I first started making these AI videos, it started back in 2023, I made my first one, and I would take my phone, come up in the kitchen, I’d play a song, and then my youngest, Layla, and I have three kids, and my oldest, Dylan, as soon as I played it, “Why are you listening to AI?” And it’s like, oh my God, instantly. It’s like, how do you know? Oh, it has this ringing sound in the thing. So it took me probably about four or five days to figure out, “Okay, what are they hearing that I’m not hearing?” So I did it, I separated all the parts, and what they’re hearing was the artifacts that are in the vocal reverb. That sound that were… That made incomplete-

It just couldn’t do the ambiances correctly, right? Because it’s trained on… A lot of these AI programs are trained on very low bit-rate MP3s, right? So, they feed all this stuff in there. So, they’re getting really inferior information in the training process, whereas now when they make these deals with the major labels, they’ll get the multitracks, and they’ll get high-quality WAV files to train from, right? And whoever opts in, they get the solo vocal tracks. You know, if Ed Sheeran wants to do it, or Drake, or whoever wants to give their voice to it, let it do its thing, and then get the royalties from it.

I’m not saying that any of them are doing it. I’m just giving an example. But every time that I would do it, I could be down the hall, and I would play something in my phone just to see if they’ll… “Why are you listening to AI?” They can instantly tell. Then it eventually started getting better. And then, it’d be like, “Is this AI?” I’d be in the car with Layla coming back from taekwondo practice, and she’s like, “Is this AI? Why? Does it sound like AI? Sounds like it could be AI.” And I’d be like, “Yeah, it’s AI.” She’s like, “Oh, it’s getting better.”

And then I did this song for… It was an NPR interview, and I created a song with a fake artist. And the song was called “Neon Ghosts,” and I played it for Layla in the car. She’s like, “Can you separate the tracks?” I said, “Yeah, I have them separated back home.” “Okay, I want to go down to hear it.” So, we go down to the studio, and I play it for her, and she listens to the soloed vocal. She said, “Wow, this is really realistic.” “This is very hard to tell, even with the soloed vocal.”

I think the room for creativity right now for humans is lyrics. It seems like the lyrics that are being generated, they lack soul somehow. And that’s- I don’t know the words correctly. I mean, they can be incredibly sophisticated, but there’s something, the edge is not there. Some kind of edge that we want in our lyrics. Some kind of surprise, but not cringe or not cliché. Or something truly novel in the lyrics. But if that’s the case, it’s kind of sad that that’s where the creativity has to come from, but not from the music. Because then if we can create very realistic music that sounds really damn good, where’s the role of the musician there?

I think the role of the musician is that in actually… If they use AI to assist them in coming up with ideas, they could as a creation tool. Then the musician… Like, some of the stuff is just not high quality sonically. So, the musician goes in and redoes stuff and changes things and adds parts, and then they actually do music production, and maybe they re-sing the parts, and they change the stuff. And then it’s just basically like an idea generator, and I think that that’s a great use of AI, is for that.

But see, if you do that, does it make you sad that you don’t necessarily need to learn instruments? So, basically, you can… I mean, you can think of it as a different kind of instrument, but you can write lyrics. You can hum the melody. You can just hum parts. You know? And then do an A/B kind of thing. Just kind of rhythm this kind of, and stitch them together. And never actually have your fingers on a guitar or fingers on a drumstick.

I’ll prompt some songs and see what they come up with and see if they’re improving on the things. But ultimately, I don’t find it interesting to use.

And there, it’s not about the… The final output is not the code. The output is what the code creates. And there, it’s extremely useful. It doesn’t matter if it’s boring or not, it’s useful. But when the final output is the thing that AI creates, which it would be in music, then there’s something about us that just, like… We know. There is something boring about it.
Lex Fridman
We want to celebrate and see the thing that’s hard to create. And if AI can just text a song, “Generate a top 10 hit,” we’ll quickly lose value for that, I think. And so, we’ll want raw. Whatever shape that raw takes, I want to say raw talent, but that raw talent of any kind. And perhaps… It would make me a little bit sad, but that’s also awesome. Perhaps the new kind of raw talent that civilization is asking for is how to make great TikToks. Maybe that’s what raw talent looks like. It makes me a little bit sad because I’m a huge fan of long-form. But that also… Creating TikToks is also talent.

Rick Beato
It is a talent. Absolutely. When I see anything that’s AI generated, I instantly recognize it. Any video, I’m like, “Ugh, boring, boring, boring.” And my kids do the same thing. They just have no interest in engaging with it. As soon as they recognize it, and they can spot it a mile away— …and they’re just like, “Boring, boring, boring, boring, boring.” And then they don’t even wanna engage with the social media platforms, which is a danger. Which I think they need to crack down on the AI slop. YouTube’s done a pretty good job on it, but it’s hard to stay on this. It gets flooded with so much of this stuff, it’s so easy to create and put up there. And to just be in the whack-a-mole thing where you’re just trying to get rid of it all is a—

Lex Fridman
And it’s annoying to have to flip through the AI slop. But I think actually, as a civilization, it’s just inspiring for authenticity ’cause you wanna be real. And being raw, which, one of the things I like about podcasts is people just shooting shit and just being themselves in the long form versus overproduced. ‘Cause I think AI is making people realize that AI is good at being overproduced. So there’ll be more.

Lex Fridman
Yeah. Even artists, ’cause you’re saying like, yeah, they’ll use it as tools. Part of me thinks like not really. Like, I think they’ll quickly, this kind of process of generating a bunch of different options and choosing the one you like the most, I think is a really frustrating process for artists. And I think it, I think AI will definitely be used extremely effectively as a very fine-grained tool in the image domain, editing images. But not like macro editing, but very specific kinda editing that Photoshop is increasingly integrated in. I’ll mention to you offline, so the whole iZotope RX group of software that does a lot of the denoising, D- All the D, removing the wind, all the—they integrate machine learning extremely effectively—

… for working with audio in different kinds of ways. There’s a bunch of different other programs that do that. Maybe for like B-roll footage and a, same thing on the audio, if you just need a little audio to create a feeling of a scene, the AI might be used there in that kinda way. But truly original stuff, eh.

Rick Beato
I’ve saved videos where I’m doing, speaking over music, for example, in an interview. Somebody’s playing and we have two people speaking in lavs, but there’s so much bleed coming from the person playing- … that you can’t hear what we’re saying. And then we’ll split out the voice for that section, the two voices, separate them- … and then take the music and separate that stuff in. So it’s really helpful for things like that.

We got Uplift Desk for my favorite office desks, BetterHelp for mental health, LMNT for electrolytes, Fin for customer service AI agents, Shopify for selling stuff online, and Perplexity for curiosity-driven knowledge exploration. Choose wisely, my friends. And now, back to my conversation with Rick Beato. So you have this video breaking down Sabrina Carpenter’s song Manchild. And you use that as an example of building up people’s intuition about the music business and how the music production for these popular songs is being done these days.

Sabrina Carpenter

Who’s doing the songwriting, how’s it being done, and all that kind of stuff? I, I was wondering if you could speak to that.

In that particular song, Jack Antonoff, who is one of the writers, Amy Allen, Sabrina Carpenter, said in some awards thing that there’s an old guy on YouTube that says that Sabrina had very little to do with the song. And so he said in this clip-

Rick Beato
Yeah, 10 people- … 11 people. I mean, you know. Like, why does Song of the Year have songs that are interpolations, meaning that they have melodies from other songs in their interpolation? They used to call it stealing. And then you have songs that use samples for the whole thing, like the Doechii song that’s out right now. And I said, “Look, she took a Gotye song and basically took off his melody and she created her own melody over it.” It’s like, well, it’s—I mean, it saves time for her. You don’t have to actually create a track; you just can sing over someone else’s song that was already successful.

Rick Beato
Right, 2011, or Luiz Bonfá in 1967. So why is that considered to be in the top songs of the year? It’s like, come on, you can’t find another song that’s not based on that? That’s ridiculous. And Doechii has some really good songs- … on her record.

… that drives them. It’s not necessarily, like, a lot of these folks are really good musicians. First of all, I think a lot of them are also good, like the actual songs they make at the top are good. I’m a big fan of Bruno Mars. He’s a great songwriter and is a great musician all around.

I mean, Taylor Swift is unlike anything. I mean, that’s a historic figure in music, but she’s a fundamentally, at least originally, a singer-songwriter. So that’s a, I mean, I’m sorry, but that is a, like, of the kind of music that Rick Beato gives props to. She’s the—she carries the flame forward.

YouTube copyright strikes
Lex Fridman
Wanna take a quick bathroom break? Okay. I have to ask you about this complexity that you’re facing on a basically daily basis. I think it’s a challenge a lot of YouTube folks experience, but you’re just so viscerally experiencing it because a lot of what you do on your channel is celebrate music, broadly. And so, as part of that process, you have to sometimes show clips of music, and I think all of that falls under fair use, quite obviously. And so you get all these YouTube copyright claims, and for folks who don’t know, if you get three of those, each one of those can be a strike on the channel and could take down your channel. And you get some insane amount. You said you got, like—I think I had a similar thing on my Rick Rubin episode—like, I think you said 13.

Rick Beato
Well, this has been going on since the beginning of my channel, and I’ve made videos periodically. When I first started, it was just instant blocks. So you never knew back in—I started, it’ll be 10 years in June. So, when I’d play music in a video, YouTubers were not playing music in videos because they didn’t, because of the Content ID things and the take-downs and stuff. So, I would play music, and I’d just see what happens, and then you get a Content ID claim, or you realize the people were, quote-unquote, “blockers,” and I came up with that term that they would block your video, take down your video.

And I realized at first it was, like, anything Guns N’ Roses, which is still the case, Guns N’ Roses, AC/DC, I mean, many bands, Fleetwood Mac, Led Zeppelin, and then, and then something happened. There was a guy on the skateboard on TikTok that had the Ocean Spray thing and he was listening to- … Dreams by Fleetwood Mac. And that blew up and became a number one song again. And the labels then realized—I mean, I’d made many videos about why this is wrong, and it should be fair use and everything. Well, because of that, the labels were like, “Ooh, maybe we should rethink this.” And then they just started demonetizing videos.

They get all the money. In a one-hour video, if they, if you use 20 seconds of a clip- … they get all the money. Okay? So, I hired a lawyer finally after the Rick Rubin video, ’cause I thought it was ridiculous. I go over to Tuscany, I interview Rick at his house, and I hired a lawyer to fight this, who I’m gonna have on my channel. I don’t wanna say who it is, but he’s another YouTuber. And he had approached me a couple years ago, and it’s not cheap to do.

So he said, “You should fight these ’cause every single one of them is fair use.” And he went through my entire catalog. I have 2,100 videos, and he’s fought 4,000 Content ID claims and won every single one of them. 4,000. That’s a lot—I mean, when I do top 20 guitar solos, there’s 20 Content ID claims, you know? It’s, and it’s either, it can be either from the sound recording, if I used that, or if I just play it, it can be from the publisher.

Rick Beato
I think that the Content ID stuff that was happening with these major labels, they would hire third parties- … that would go out, use AI, and go and anytime they detect anything, they always go to the biggest channels first to get the most views. Makes sense and stuff. And they would claim everything that they could, and historically, YouTubers never would fight back. They were like, “Oh, this is easy money.” YouTubers never fight back at these things, because they’re afraid to have their channels taken down. So-

Spotify
Lex Fridman
I mean, hopefully, there’s a ripple effect also. It’s not just your situation. Hopefully, you don’t have to deal with this for much longer. How has Spotify changed music? Sometimes we highlight the fact that they changed the nature of music and that the scarcity is not there. But also, a lot of it’s like every kind of music is available and so fast and it’s so easy. It’s easy to explore.

… that there’s some good to… I mean, there’s a lot of good to that, right? Well, have you… Did you go through that whole process? I still remember where I had to basically throw away the albums.
… that there’s some good to… I mean, there’s a lot of good to that, right? Well, have you… Did you go through that whole process? I still remember where I had to basically throw away the albums.
Rick Beato
I never did that. When? After you uploaded them into your computer?
I never did that. When? After you uploaded them into your computer?
Lex Fridman
Yeah. So, there’s that two-step process. One, there’s like the hard albums, CDs for me.
Yeah. So, there’s that two-step process. One, there’s like the hard albums, CDs for me.
Rick Beato
CDs, yep.
CDs, yep.
Lex Fridman
And then, and then you upload them into your computer. And you save them. And then how do you put it? Allegedly, a friend of yours pirates some extra songs. And puts them on the computer. So, you have… but you have your stash on the computer. You’re like, “This is my finely selected stash of greatness.” Uh, sometimes organized by album, sometimes not. And the big moment for me that was really difficult to do, really difficult to do, is throw away that stash and switch to Spotify.

Lex Fridman
Switch to streaming, and basically, rebuild the stash of playlists and all this kind of stuff. And that, it was heartbreaking ’cause so much love and effort went into that. Both the CD, the stashing of the CD, and the stashing of the MP3s in the computer. And then in Spotify, it just seems just effortless. But it helped me discover all kinds of artists I never would have discovered otherwise. And Pandora, I used a lot. Pandora is more prioritizing on the discovery part versus organization part. And that was really wonderful.

So, one of the things I… I’ll start with a positive that I like about Spotify, is that they show view count, they show play counts. Whether they’re real or not, that’s another question. But they show how many plays songs have, and that’s how the charts are based.

Does that give you signal that something is listened to a billion times? Does that mean something to you?
Does that give you signal that something is listened to a billion times? Does that mean something to you?
Rick Beato
Yeah. It means that it’s a popular song. Well, that’s a massive hit. There’s very few songs that have a billion plays. Now, the downside of Spotify is the way that they pay their artists. Now they’ve lumped in podcasts that are getting a cut of this streaming with the music. And you know, the search and discovery. I mean, there’s benefits of algorithms and there’s negative things of algorithms. Algorithms happen to many times pigeonhole people into listening to the same genre of music all the time, and not expanding their discovery of new music. Where you might hear on the radio back in the day where program directors would play things that they liked, right?

And you might hear something, “Oh, what is that?” “Oh, that’s a new Soundgarden record,” or you know, like, “Whoa, I like that. I’m gonna go check that out.” You know, something you might not have heard or something odd.

Like, one thing I really love doing on Spotify is you can… you can have radio.

I need motivation. Classical music? I don’t know. But yeah, it’s pretty good ’cause it recommends a bunch of other stuff I wouldn’t even know. Some of it I know, obviously, but akin to the, similar to the Rage Against the Machine-y type thing.

It recommends a bunch of artists, and it’s like, “Oh, holy shit, that’s awesome.” So, I don’t know. That discovery works really well. So, some of it is the technology thing. But that experience was fundamentally more vibrant than I had previously with my stash. That I would just keep a stash, and I would listen to the same record over and over and over and over. But yeah, what’s lost is the, I’m sure you love this, but listening through the Led Zeppelin records, just driving in a car and listening to the whole thing all the way through. Yeah, that’s lost.

And it’s funny that when I interview a mixer, I interviewed this mixing engineer, Andy Wallace, and people comment, “Wow, the song sounded amazing.” And you go, “Well, not only are they great mixes that he did, but I’m using WAV files in there.” And people notice the, and these are WAV files from original encoding.

If I didn’t have a Mac, honestly, I wouldn’t be talking to you right now.

And I learned how to use Pro Tools, and that allowed me to learn how to edit video and become a record producer. So I gotta give it to Macs for that.

I gotta ask you ’cause I know… I’ve never used Pro Tools. I’ve used… Again, I’m a caveman. I’ve used REAPER, I’ve used Studio One, that’s the most recent that I’ve used that. And- … for the most time I’ve used Ableton Live. I feel like I’m using 1% of the power of the tool. Like, Ableton Live makes me feel like I’m literally just pressing the record button.

And the, it’s, it’s… I mean, I sound, I sound really out of touch. But it, it’s just the power is incredible. Also, it’s, I think it’s not just for recording, it’s also for live performances. So this is why Studio One has been a little bit nicer for me, because it’s simpler, made for recording more so.

Then it’s like, no, I need more of like a scooped metal sound that’s more like Metallica or Dream Theater or something, so, oh, I’m gonna pull out my Mesa/Boogie. Or I need something that’s chimey that’s more like Brian May or like The Edge, I’m gonna pull out my Vox AC30.

And I have a Guild 12-string, and I have a Guild Nashville-tuned guitar. The low strings are up the octave, so the E, A, D and G are up the octave. That’s Nashville tuning. Six-string though. Like, basically what David Gilmour plays on Comfortably Numb in my video. He plays a Nashville tune, but with one variation. The low E is up two octaves. So he demonstrates actually the… And this is how he wrote Comfortably Numb. The, the chorus-

Advice

By way of advice, you started your YouTube channel in your mid-50s and found incredible success. You’ve had essentially multiple careers. Is there some wisdom you can extract from that?

Rick Beato
So my theory is that somebody’s gotta be successful, so why can’t it be you? That was my… When I started my channel, I mean, I didn’t start it to… It started by accident with the Dylan video. And really, so many people reached out to me. I started it six months after that viral video. So many people wrote to me, “Can you teach me this?” Pro musicians, well-known ones who you’d know. “Can you teach me this?” I can’t teach you what Dylan did, but I can teach you relative pitch, develop your ear that way. But then I had conservatories writing to me about this stuff from all over the world. “How did you teach Dylan this?” ‘Cause we made about four different videos, and they got more and more sophisticated.

And so I thought, “Okay, I’ll make some YouTube videos and explain this stuff.” This is, that’s really why I started, so I didn’t have to keep… I couldn’t answer the emails. There were so many of them, so I just started making videos on how to train your ear and music theory. And that’s really how I started my channel, and my wife was like, “What are you doing?” I said, “I’m making YouTube videos.” “Why?” So I don’t have to keep telling people how I did this stuff. And then all of a sudden, you know, I had 4,000 subscribers the first month, another 4,000 then. Hit 100,000 after a year, and then six months later, 200,000, then three months later, 300,000. So-

I think there’s one thing that should be said, that in modern culture for young people, a lot of them will see YouTube and TikTok and Instagram, and they kinda wanna be famous. They wanna get the clicks and the views and so on, and that’s the thing they chase and optimize. I think the thing that you’re leaving unstated perhaps is that you spent many years pursuing the mastery of a craft. And there’s a lot of value to getting good at something.

They wanna get the clicks and the views and so on, and that’s the thing they chase and optimize. I think the thing that you’re leaving unstated perhaps is that you spent many years pursuing the mastery of a craft. And there’s a lot of value to getting good at something.
Rick Beato
Absolutely.
Absolutely.
Lex Fridman
Offline. You can actually reveal your journey online, but the thing you’re chasing is not fame. It’s getting good at s- something. And I think actually what happens is even if the thing you get good at… is not the thing that you become famous for, if that’s the thing that ends up happening. It’s still, like, getting good at one thing, kind of somehow relates to getting good at another thing. Somehow they’ll lead you to get better at getting better at the next thing, at the next thing, and the next thing. But if you’re just chasing fame and trying to figure out, “How do I do the viral thing?” or so on, it just seems to… You might actually get there, but it’ll be unfulfilling and not long-lasting.

My theory of my channel has always been, make videos on things I’m interested in. And at first, I thought, “Oh, nobody’s going to watch an old white-haired guy on YouTube.” That was kind of my thing. Well, that was not correct. And then it’s like, “Well, just make videos on stuff I’m interested in.” It just so happens that other people are interested in the same things I’m interested in. And keep learning. And when I produced bands, I never let them take my picture, ever. I never let them record me in the studio. There’s virtually no pictures of any band I ever produced. So from 1999 to 2015 when that Dylan video came out, no one took my picture. There were no pictures of me on the internet.

Lex Fridman
And now you’re like… you’re the talent. You’re the face. No, I mean, but then again, the thing you’re leaving unstated there is like you spent a lot of years teaching music. Like, really exploring music. Trying a music career of like, trying to create, trying to produce, trying to be a musician, and all these… Not just trying. Like, being a, getting extremely good at it. I just, I think in modern culture there’s a sense you want to skip that part. “I wanna be famous. I wanna…” You know this. And that is a thing that’s not going to be in most cases effective as a primary thing to chase.

So I have an undergrad in classical bass. I have a master’s from New England Conservatory in jazz guitar. Then I taught college for… I taught jazz studies for five years- … from ’87- … to ’92. Then I got a publishing deal, my first publishing deal, in 1992- … with PolyGram Publishing. And then I became a producer when I was 37, having no idea how to engineer, I taught myself engineering. And then YouTube. I taught myself how to edit videos.

By the way, before I forget, I think I speak for the entirety of the internet thanking you for how you introduce your videos and how you close them. ‘Cause you, this is a big part of YouTube, where people have a 30-minute introduction to a five-minute video. You just go straight in. That’s really wonderful. That’s, I mean, on all fronts. I mean, I suppose that has to do with the production skills that you have, of understanding, cutting, cutting the fluff.

Rick Beato
Yeah. That’s one of my things is that I really value the time I’ve spent with people—friendships and keeping in touch with people. I talk to each one of my siblings multiple times a week. I talk to my sisters probably every night, my two sisters. I have friends from college, I got friends from growing up, I have friends from, you know, both colleges I went to. I have friends from all different eras in my life that I keep in touch with and visit whenever I can, and…

It is, right? Music does something. I’ll get… sometimes when I’m alone I’ll listen to a song, and there’s nothing quite like a song that makes me truly feel, like feel alive. And whatever that is: sadness, or hope, or excitement. Or when I’m working out, listening to Rage Against the Machine—like protest. Or as I was listening to Metallica, I was re-listening to the set that they played in Moscow, just hyped. Like truly hyped. I was like pacing listening to it. And there’s nothing like that.

I watched my agent happily click the “I’m not a robot” button. I made the agent very aware. Like, it knows what his source code is. It understands th- how it sits and runs in its own harness. It knows where documentation is. It knows which model it runs. It understands its own system that made it very easy for an agent to… Oh, you don’t like anything? You just prompted it to existence, and then the agent would just modify its own software. People talk about self-modifying software, I just built it. I actually think wipe coding is a slur.

Introduction
Lex Fridman
The following is a conversation with Peter Steinberger, creator of OpenClaw, formerly known as MoldBot, ClawedBot, Clawdus, Claude, spelled with a W as in lobster claw. Not to be confused with Claud, the AI model from Anthropic, spelled with a U. In fact, this confusion is the reason Anthropic kindly asked Peter to change the name to OpenClaw. So, what is OpenClaw? It’s an open-source AI agent that has taken over the tech world in a matter of days, exploding in popularity, reaching over 180,000 stars on GitHub, and spawning the social network mold book, where AI agents post manifestos and debate consciousness, creating a mix of excitement and fear in the general public.

And a kind of AI psychosis, a mix of clickbait fearmongering and genuine, fully justifiable concern about the role of AI in our digital, interconnected human world. OpenClaw, as its tagline states, is the AI that actually does things. It’s an autonomous AI assistant that lives in your computer, has access to all of your stuff, if you let it, talks to you through Telegram, WhatsApp, Signal, iMessage, and whatever else messaging client. Uses whatever AI model you like, including Claude Opus 4.6 and GPT 5.3 Codex, all to do stuff for you. Many people are calling this one of the biggest moments in the recent history of AI, since the launch of ChatGPT in November 2022.

The ingredients for this kind of AI agent were all there, but putting it all together in a system that definitively takes a step forward over the line from language to agency, from ideas to actions, in a way that created a useful assistant that feels like one who gets you and learns from you, in an open source, community-driven way, is the reason OpenClaw took the internet by storm. Its power, in large part, comes from the fact that you can give it access to all of your stuff and give it permission to do anything with that stuff in order to be useful to you. This is very powerful, but it is also dangerous. OpenClaw represents freedom, but with freedom comes responsibility.

With it, you can own and have control over your data, but precisely because you have this control, you also have the responsibility to protect it from cybersecurity threats of various kinds. There are great ways to protect yourself, but the threats and vulnerabilities are out there. Again, a powerful AI agent with system-level access is a security minefield, but it also represents the future. Because when done well and securely, it can be extremely useful to each of us humans as a personal assistant. We discuss all of this with Peter, and also discuss his big-picture programming and entrepreneurship life story, which I think is truly inspiring. He spent 13 years building PSPDF Kit, which is a software used on a billion devices.

He sold it, and for a brief time, fell out of love with programming, vanished for three years, and then came back, rediscovered his love for programming, and built, in a very short time, an open source AI agent that took the internet by storm. He is, in many ways, the symbol of the AI revolution happening in the programming world. There was the ChatGPT moment in 2022, the DeepSeek moment in 2025, and now, in ’26, we’re living through the OpenClaw moment, the age of the lobster. The start of the agentic AI revolution. What a time to be alive. This is a Lex Fridman podcast.

OpenClaw origin story
Lex Fridman
The one and only, the Clawed Father. Actually, Benjamin predicted it in his tweet. “The following is a conversation with Claude, a respected crustacean.” It’s a hilarious-looking picture of a lobster in a suit, so I think the prophecy has been fulfilled. Let’s go to this moment when you built a prototype in one hour, that was the early version of OpenClaw. I think this story’s really inspiring to a lot of people because this prototype led to something that just took the internet by storm…. and became the fastest-growing repository in GitHub history, with now over 175,000 stars. So, what was the story of the one-hour prototype?

Peter Steinberger
Yeah. And I, I played around with some other things, like even stuff that gets all my WhatsApp, and I could just run queries on it. That was back when we had GPT-4.1, with the one million context window. And I, I pulled in all the data and then just asked him questions like, “What makes this friendship meaningful?”

Peter Steinberger
Yeah. But then I… I thought all the labs will, will, will work on that. So I, I moved on to other things, and that was still very much in my early days of experimenting and pl- playing. You know, you have to… That’s how you learn. You just like, you do stuff and you play. And time flew by and it was November. I wanted to make sure that the thing I started is actually happening. I was annoyed that it didn’t exist, so I just prompted it into existence.

I mean, that’s the beginning of the hero’s journey of the entrepreneur, right? And you’ve even with your original story with PS PDF kit, it’s like, “Why does this not exist? Let me build it.” And again, here’s diff- a whole different realm, but similar maybe spirit.

Yeah. Like the most, the most random thing ever. And suddenly, I had this problem and I, I wanted to help a friend. And there was, there was… Well, not like nothing existed, but it was just not good. And like… Like I tried it and it was like very, “Nah.” Like, “Hmm, I can do this better.”

Anyway, so you said “Screw it. Why don’t I do it?” So what was the… What was the prototype? What was the thing that you… What was the magical thing that you built in a short amount of time that you were like, “This might actually work as an agent,” where I talk to it and it does things?

There was… Like, one of my projects before already did something where I could bring my terminals onto the web and then I could, like, interact with them, but there also would be terminals on my Mac.

Viptunnel, which was like a, a weekend hack project that was still very early. And it was cloud code times. You know, you got a dopamine hit when you got something right. And now I get, like, mad when you get something wrong.

And you had a really great -– not to take a tangent -– but a great blog post describing that you converted Viptunnel. You vibe-coded Viptunnel from TypeScript into Zig of all programming languages with a single prompt. One prompt, one shot. Convert the entire code base into Zig.

Yeah. There was this one thing where part of the architecture was… Took too much memory. Every terminal used like a node. And I wanted to change it to Rust and… I mean, I can do it. I can, I can manually figure it all out, but all my automated attempts failed miserably. And then I revisited about four or five months later. And I’m like, “Okay, now let’s use something even more experimental.” And I, and I just typed, “Convert this and this part to Sig,” and then let Codex run off. And it basically got it right. There was one little detail that I had to, like, modify afterwards, but it just ran for overnight or like six hours and just did its thing. And it’s like… It’s just mind-blowing.

So that’s on the LLM programming side, refactoring. But uh, back to the actual story of the of the prototype. So how did Viptunnel connect to the first prototype where your, like, agents can actually work?

Well, that was still very limited. You know, like I had this one experiment with WhatsApp, then I had this experiment, and both felt like not the right answer. And then my search bar was literally just hooking up WhatsApp to cloud code. One shot. The CLI message comes in. I call the CLI with -p. It does its magic, I get the string back and I send it back to WhatsApp. And I, I built this in one hour. And I felt… Already felt really cool. It’s like, “Oh, I could… I can, like, talk to my computer,” right? This… That, that was, that was cool. But I, I wanted images, ’cause I alw- I often use images when I prompt. I think it’s such a, such an efficient way to give the agent more context.

And they are really good at figuring out what I mean, e- even if it’s like a, a weird cropped-up screenshot. So I used it a lot and I wanted to do that in WhatsApp as well. Also, like, you know, just you run around, you see like a poster of an event, you just make a screenshot and like figure out if I have time there, if this is good, if my friends are maybe up for that. Just like images seemed im- important. So I, I worked a few… It took me a few more hours to actually get that right. And then it was just…… I, I used it a lot. And funny enough, that was just before I went on a trip to Marrakesh with my friends for a birthday trip. And there it was even better because internet was a little shaky but WhatsApp just works, you know?

It’s like doesn’t matter, you have, like, edge, it still works. WhatsApp is just… It’s just made really well. So I ended up using it a lot. Translate this for me, explain this, find me places. Like, you just having a clanker doing, having Google for you, that was… Basically there was still nothing built but it still could do so much.

Lex Fridman
So, if we talk about the full journey that’s happening there with the agent, you’re just sending on this very thin line WhatsApp message via CLI, it’s going to a cloud code and cloud code is doing all kinds of heavy work and coming back to you with a thin message.

Yeah. It was slow because every time I boot up the CLI, but it… It was really cool already. And it could just use all the things that I already had built. I had built like a whole bunch of CLI stuff over the month so it, it felt really powerful.

There is something magical about that experience that’s hard to put into words. Being able to use a chat client to talk to an agent, versus, like, sitting behind a computer and like, I don’t know, using cursor or even using Cloud Code CLI in the terminal. It’s a different experience than being able to sit back and talk to it. I mean, it seems like a trivial step but, it- in some sense it’s a… It’s like a phase shift in the integration of AI into your life and how it feels, right?

Yeah. Yeah. I, I read this tweet this morning where someone said, “Oh, there’s no magic in it. It’s just like, it does this and this and this and this and this and this.” And it almost feels like a hobby, just as cursor or perplexity. And I’m like, well, if that’s a hobby that’s kind of a compliment, you know? They’re like, they’re not doing too bad. Thank you I guess? Yes. I mean, isn’t, isn’t, isn’t magic often just like you take a lot of things that are already there but bring them together in new ways? Like, I don’t… There’s no… Yeah. Maybe there’s no magic in there but sometimes just rearranging things and, like, adding a few new ideas is all the magic that you need.

It’s really hard to convert into words what is, what is magic about a thing. If you look at the, the scrolling on an iPhone, why is that so pleasant? There’s a lot of elements about that interface that makes it incredibly pleasant, that is fundamental to the experience of using a smartphone, and it’s like, okay, all the components were there. Scrolling was there, everything was there.

Right? But still… You know the moment where it, it blew my mind was when, when I- I used it a lot and then at some point I just sent it a message and, and then a typing indicator appeared. And I’m like, wait, I didn’t build that, it only m- it only has image support, so what is it even doing? And then it would just reply.

Oh, just a random question like, “Hey, what about this in this restaurant?” You know? Because we were just running around and checking out the city. So that’s why I, I didn’t, didn’t even think when I used it because sometimes when you’re in a hurry typing is annoying.

I literally went, “How the fuck did he do that?” And it was like, “Yeah, the mad lad did the following. He sent me a message but it only, only was a file and no file ending.” So I checked out the header of the file and it found that it was, like, opus so I used ffmpeg to convert it and then I wanted to use whisper but it didn’t had it installed. But then I found the OpenAI key and just used Curl to send the file to OpenAI to translate and here I am.

You didn’t teach it any of those things and the agent just figured it out, did all those conversions, the translations. It figured out the API, it figured out which program to use, all those kinds of things. And you were just absent-mindedly just sent an audio message when it came back.

Yeah, like, so clever even because he would have gotten the whisper local path, he would have had to download a model. It would have been too slow. So like, there’s so much world knowledge in there, so much creative problem solving. A lot of it I think mapped from… If you get really good at coding that means you have to be really good at general purpose problem solving. So that’s a skill, right? And that just maps into other domains. So it had the problem of like, what is this file with no file ending? Let’s figure it out. And that’s when it kind of clicked for me. It’s like, I was like very impressed. And somebody sent a pull request for Discord support and I’m like, “This is a WhatsApp relay.

And then some people came and tried to hack it, and I just… Or, like, just watched and I just kept working in the open, you know? Like, y- I used my agent to build my agent harness and to test, like, various stuff. And that’s very quickly when it clicked for people. So it’s almost like it needs to be experienced. And from that time on, that was January the 1st, I, I got my first real influencer being a fan and did videos, dachitze. Thank you. And, and from there on, I saw, I started gaining up speed. And at the same time, my, my sleep cycle went shorter and shorter because I, I felt the storm coming, and I just worked my ass off to get it to…

What can I do there? How can I be smart at queuing messages? How can I make it more human-like? Oh, then I had this idea of… Because the loop always… The agent always replies something, but you don’t always want an agent to reply something in a group chat. So I gave him this no-reply token. So I gave him an option to shut up. So it, it feels more natural.

And then the, the agent… I made the agent very aware. Like, it knows that it is… What its source code is. It understands th- how it sits and runs in its own harness. It knows where documentation is. It knows which model it runs. It knows if you turn on the voice or, or reasoning mode. Like, I, I wanted to be more human-like, so it understands its own system that made it very easy for an agent to… Oh, you don’t like anything?

Oh, because that’s how I built it as well, you know? Most of it is built by Codex, but oftentimes I… When I debug it, I…… I use self-introspection so much. It’s like, “Hey, what tools do you see? Can you call the tool yourself?” Or like, “What error do you see? Read the source code. Figure out what’s the problem.” Like, I just found it an incredibly fun way to… That the agent, the very agent and software that you use is used to debug itself, so that it felt just natural that everybody does that. And that it led to so many, so many pull requests by people who never wrote software. I mean, it also did show that people never wrote software . So I call them prompt requests in the end.

Figure out what’s the problem.” Like, I just found it an incredibly fun way to… That the agent, the very agent and software that you use is used to debug itself, so that it felt just natural that everybody does that. And that it led to so many, so many pull requests by people who never wrote software. I mean, it also did show that people never wrote software . So I call them prompt requests in the end.
Peter Steinberger
But I don’t want to, like, pull that down because every time someone made the first pull request is a win for our society, you know? Like, it… Like, it doesn’t matter how, how shitty it is, y- you gotta start somewhere. So I know there’s, like, this whole big movement of people complain about open source and the quality of PRs, and a whole different level of problems. But on a different level, I found it… I found it very meaningful that, that I built something that people love to think of so much that they actually start to learn how open source works.

Lex Fridman
Yeah, you were … The Open Cloud project was the first pull request. You were the first for so many. That is magical. So many people that don’t know how to program are taking their first step into the programming world with this.

Yeah. Like, the bar to do that was so high, and, like, with agents, and with the right software, it just, like, went lower and lower. I don’t know. I was at a… And I also organize another type of meetup. I call it… I called it Cloud Code Anonymous. You can get the inspiration from. Now, I call it Agents Anonymous- … for, for reasons.

Peter Steinberger
Yeah. And there was this one guy who, who talked to me. He’s like, “I run this design agency, and we, we never had custom software. And now I have, like, 25 little web services for various things that help me in my business. And I don’t even know how they work, but they work.” Uh, and he was just, like, very happy that my stuff solved some of his problems. And he was, like, curious enough that he actually came to, like, a, a Enchantic meetup, even though he’s… He doesn’t really know how software works.

Name-change drama

Peter Steinberger
Yeah. You know, when I, when I built it in the beginning, my agent had no personality. It was just… It was Claude Code. It’s like this sycophantic opus, very friendly. And I… When you talk to a friend on WhatsApp, they don’t talk like Claude Code. So I wanted… I, I felt this… I just didn’t f- It didn’t feel right, so I, I wanted to give it a personality.

Partially, it picked up a little bit from me. You know, like those things are text completion engines in a way. So, so I, I, I, I had fun working with it, and then I told it to… How I wanted it to interact with me, and just, like, write your own agents.md give yourself a name. And then we… I didn’t even know how the whole, the whole lobster… I mean, people only do lobster… Originally, it was actually a lobster in a, in a TARDIS, because I’m also a big Doctor Who fan.

… the TARDIS is basically the, the harness, but cannot call it TARDIS, so we called it Claude’s. So that was name number two.

Which is part of what makes it funny, I think. The play on the letters and the words in the TARDIS and the lobster and the space lobster is hilarious. But I can see why it can lead into problems.

Peter Steinberger
Yeah, they didn’t find it so funny . So then I got the domain ClaudeBot, and I just… I love the domain. And it was, like, short. It was catchy. I’m like, “Yeah, let’s do that.” I didn’t… I didn’t think it would be that big at this time. And then just when it exploded, I got, Kudos, a very friendly email from one of the employees that they didn’t like the name.

Yeah. So actually, Kudos, because they shou- could have just sent a, a lawyer letter, but they’ve been nice about it. But also like, “You have to change this and fast.” And I asked for two days, because changing a name is hard, because you have to find everything, you know, Twitter handle, domains, NPM packages Docker registry, GitHub stuff. And everything has to be…… you need a set of everything.

And also, can we comment on the fact that you’re increasingly attacked, followed by crypto folks? Which I think you mentioned somewhere that that means the name change had to be… Because they were trying to snipe, they were trying to steal, and so you had to be… The, the na- I mean, from an engineering perspective, it’s just fascinating. You had to make the name change Atomic, make sure it’s changed everywhere at once.

I, I underestimated those people. It’s a, it’s a very interesting subculture. Like, it… Everything circles around… I’ll probably get a lot wrong and we’ll probably get hate for that if you say that, but… There is like Bags app and then they, they tokenize everything. And th- they did the same back with Swipe Tunnel, but to a much smaller degree. It was not that annoying. But on this project, they’ve been, they’ve been swarming me. They, they… It’s like every half an hour, someone came into Discord and, and, and spammed it and we had to block the p- We have, like, server rules, and one of the rules was… One of the rules is no mentioning of butter. For obvious reasons. And one was, no talk about finance stuff or crypto. Because I’m…

Peter Steinberger
I- I’m just not interested in that, and this is a space about the project and not about some finance stuff. But yeah. They came in and, and spammed and… Annoying. And on Twitter, they would ping me all the time. My, my notification feed was unusable. I, I could barely see actual people talking about this stuff because it was like swarms.

And everybody sent me the hashes. Um… And they all try me to claim the fees. Like, “Are you helping the project?” Claim the fees. No, you’re actually harming the project. You’re, like, disrupting my work, and I am not interested in any fees. I’m… First of all, I’m financially comfortable. Second of all, I don’t want to support that because it’s so far the worst form of online harassment that I’ve experienced.

Yeah. There’s a lot of toxicity in the crypto world. It’s sad because the technology of cr- cryptocurrency is fascinating, powerful and maybe will define the future of money, but the actual community around that, there’s so much to- toxicity, there’s so much greed. There’s so much trying to get a shortcut to manipulate, to, to steal, to snipe, to, to, to, to game the system somehow to get money. All this kind of stuff that… Uh… I mean, it’s the human nature, I suppose, when you connect human nature with money and greed and and especially in the online world with anonymity and all that kind of stuff. But from the engineering perspective, it makes your life challenging. When Anthropic reaches out, you have to do a name change.

Peter Steinberger
Yeah. There was no perfect name, and I didn’t sleep for two nights. I was under high pressure. Um, I was trying to get, like, a good set of domains and, you know, not cheap, not easy, ’cause in this, in this state of the internet, you basically have to buy domains if you want to have a good set. And, and then another ca- another email came in that the lawyers are getting uneasy. Again, friendly, but also just adding more stress to my situation already. So at this point I was just like, “Sorry, there’s no other word. Fuck it.” And I just, I just renamed it to Mod Bot ’cause that was the set of domains I had. I was not really happy, but I thought it’ll be fine. And I tell you, everything that could go wrong- … did go wrong. Everything that could go wrong did go wrong.

Peter Steinberger
Well, the, the interesting stuff is that none of these services have, have a squatter protection. So, I had two browser windows open. One was like a, an empty account ready to be rename- renamed to Claude Bot, and the other one I renamed to Mod Bot. So, I pressed rename there, I pressed rename there, and in those five seconds, they stole the account name. Literally, the five seconds of dragging the mouse over there and pressing rename there was too long.

Wow.
Wow.
Peter Steinberger
Because there’s no… Those systems… I mean, you would expect that they have some protection or, like, an automatic forwarding, but there’s nothing like that. And I didn’t know that they’re not just good at harassment, they’re also really good at using scripts and tools.

Yeah.
Peter Steinberger
So, yeah. So, suddenly, like, the old account was promoting new tokens and serving malware. And I was like, “Okay, let’s move over to GitHub,” and I pressed rename on GitHub. And the GitHub renaming thing is slightly confusing, so I renamed my personal account. And in those… I guess it took me 30 seconds to realize my mistake. They sniped my account, serving malware from my account. So, I was like, “Okay, let’s at least do the NPM stuff,” but that takes, like, a minute to upload. They sniped, they sniped the NPM package, ’cause I could reserve the account, but I didn’t reserve the root package…. so like everything that could go wrong , like went wrong.

Can I just ask a, a curious question of, in that moment you’re sitting there, like how shitty do you feel? That’s a pretty hopeless feeling, right?
Peter Steinberger
Yeah. Because all I wanted was like having fun with that project and to keep building on it. And yet here I am like days into researching names, picking a name I didn’t like. And having people that claimed they helped me making my life miserable in every possible way. And honestly, I was that close of just deleting it. I was like, “I did show you the future, you build it.”

I… That was a big part of me that got a lot of joy out of that idea. And then I thought about all the people that already co- contributed to it, and I couldn’t do it because they had plans with it, and they put time in it. And it just didn’t feel right.

And now like how do you even, how do you undo that? You know, l- luckily, and thankfully, like I, I have… Because I have a little bit of following already. Like I had friends at Twitter, I had friends at GitHub who like moved heaven and earth to like help me. And it is not… That’s not something that’s easy. Like, like GitHub tried to like clean up the mess and then they ran into like platform bugs . ‘Cause it’s not happening so often that things get renamed on that level. So, it took them a few hours. The MBM stuff was even more difficult because it’s a whole different team. On the Twitter side, things are not as easy as well. It, it took them like a day to really also like do the redirect. And then I also had to like do all the renaming in the project.

Then there’s also ClaudeHub, which I didn’t even finish the rename there because I, I, I managed to get people on it and then someone just like collapsed and slept. And then I woke up and I’m like, I made a, a beta version for the new stuff and I, I just, I just couldn’t live with the name. It’s like, you know… But but, you know, it’s just been so much drama. So, I had the real struggle with me like I never want to touch that again, and I really don’t like the name. So, and I… There was also this like… Then there was all the security people that started emailing me like mad. Um, I was bombarded on Twitter, on email. There’s like a thousand other things I should do. And I’m like thinking about the name which is like, it should be like the least important thing.

Oh, that it’s like, “Please tell me this is fine.” I don’t think they can actually claim that, but it felt like the right thing to do. And I did another rename. Like just Codex alone took like 10 hours to rename the project ’cause it, it’s a bit more tricky than a search replace and I, I wanted everything renamed, not just on the outside. And that rename, I, I felt I had like my, my war room. But then I, I had like some contributors really that helped me. We made a whole plan of all the names we have to squat.

And like with reloading, it’s like, “Okay, they don’t, they don’t expect anything yet.” Then I created a few decoy names. And all the shit I shouldn’t have to do. You know? Like, you know-

It’s so s- … so stupid. Uh like I still was like, “Oh, should I, should I keep it?” Then I was like, “No, the mold’s not growing on me.” And then I think I had final all the pieces together. I didn’t get a .com but, yeah, it’s been like quite a bit of money on the other domains. I tried to reach out again to GitHub but I feel like I, I used up all my goodwill there, so I…

… But that didn’t happen and then so I did that the f- as first thing. Uh, Twitter people were very supportive. I, I actually paid 10K for the business account so I could claim the-… OpenClaw, which was, like, unused since 2016, but was claimed. And yeah, and then I finally … This time I managed everything in one go. Nothing, almost nothing got wrong. The only thing that did go wrong is that I was not allowed by trademark rules to get OpenClaw.AI, and someone copied the website as serving malware.

I’m not even allowed to keep the redirects. Like, I have to return … Like, I have to give Entropik the domains, and I cannot do redirects, so if you go on claw.bot next week, it’ll just be a 404.

And I- I’m not sure how trademark … Like, I didn’t, I didn’t do that much research into trademark law, but I think that could, could be handled in a way that is safer, because ultimately those people will then Google and maybe find malware sites that I have no control on them.

The point is, that whole saga made a dent in your whole f- the funness of the journey, which sucks. So, let’s just, let’s just get, I suppose, get back to fun. And during this, speaking of fun, the two-day MoltBot saga.

MoltBook was created.
MoltBook was created.
Peter Steinberger
Yeah.
Yeah.
Lex Fridman
Which was another thing that went viral as a kind of demonstration, illustration of how what is now called OpenClaw could be used to create something epic. So for people who are not aware, MoltBook is just a bunch of agents talking to each other in a Reddit-style social network. And a bunch of people take screenshots of those agents doing things like scheming against humans. And that instilled in folks a kind of, you know, fear, panic, and hype. W- what are your thoughts about MoltBook in general?

I- I saw it before going to bed, and even though I was tired, I spent another hour just reading up on that and, and just being entertained. I, I just felt very entertained, you know? The- I saw the the reactions, and, like, there was one reporter who’s calling me about, “This is the end of the world, and we have AGI.” And I’m just like, “No, this is just, this is just really fine slop.” You know, if, if I wouldn’t have created this, this whole onboarding experience where you, you infuse your agent with your personality and give him, give him character, I think that reflected on a lot of how different the replies to MoltBook are. Because if it were all, if it were all be ChatGPT or Cloud Code, it would be very different. It would be much more the same.

But because people are, like, so different, and they create their agents in so different ways and use it in so different ways, that also reflects on how they ultimately write there. And also, you, you don’t know how much of that is really done autonomic, autonomous, or how much is, like, humans being funny and, like, telling the agent, “Hey, write about the deep plan, the end of the world, on MoltBook, ha, ha, ha.”

Well, I think, I mean, my criticism of MoltBook is that I believe a lot of the stuff that was screenshotted is human prompted. Which, just look at the incentive of how the whole thing was used. It’s obvious to me at least that a lot of it was humans prompting the thing so they can then screenshot it and post it on X in order to go viral.

For real. Like, kudos to, to Matt, who had this idea so quickly and pushed something out. You know, it was, like, completely insecure security drama. But also, what’s the worst that can happen? Your agent account is leaked, and, like, someone else can post slop for you? So like, people were, like, making a whole drama about of the security thing, when I’m like, “There’s nothing private in there.

Yeah, but that- that’s still, like, to me, really concerning, because of how the journalists and how the general public reacted to it. They didn’t see it. You have a kind of lighthearted way of talking about it like it’s art, but it’s art when you know how it works. It’s extremely powerful viral narrative creating, fearmongering machine if you don’t know how it works. And I just saw this thing.

Oh, there’s … Some people are just way too trusty or gullible. You know, they … I literally had to argue with people that told me, “Yeah, but my agent said this and this.” So, I feel we, as a society, we need some catching up to do in terms of understanding that AI is incredibly powerful, but it’s not always right. It’s not, it’s not all-powerful, you know? And, and especially-… it’s like things like this, it’s, it’s very easy that it just hallucinates something or just comes up with a story.

So I d- think that’s a really good point you’re making about contextualizing properly what AI is, but also realizing that there is humans who are drama farming behind AI. Like, don’t trust screenshots. Don’t even trust this project, MoltBook, to be what it represents to be. Like, you can’t … and, and by the way, you speaking about it as art. Yeah, don’t … Art can be in many levels and part of the art of MoltBook is, like, putting a mirror to society. ‘Cause I do believe most of the dramatic stuff that was screenshotted is human-created, essentially. Human prompted. And so, like, it’s basically, look at how scared you can get at a bunch of bots chatting with each other. That’s very instructive about …

Lex Fridman
because I think AI is something that people should be concerned about and should be very careful with because it’s very powerful technology, but at the same time, the only thing we have to fear is fear itself. So there’s like a line to walk between being seriously concerned, but not fearmongering because fearmongering destroys the possibility of creating something special with a thing.

To me the … in the beginning I was, I was just very annoyed ’cause a lot of the stuff that came in was in the category, yeah, I put the web backend on the public internet and now there’s like all these, all these CVSSs. And I’m like screaming in the docs, don’t do that. Like, like this is the configuration you should do. This is your local host debug interface. But because I made it possible in the configuration to do that, it totally classifies as a remote code or whatever all these exploits are. And it took me a little bit to accept that that’s how the game works and I’m, we making a lot of progress.

But there’s still, I mean on the security front for OpenClaw, there’s still a lot of threats or vulnerabilities, right? So like prompt injection is still an open problem in the, i- industry-wide. When you have a thing with skills being defined in a markdown file, there’s so many possibilities of obvious low-hanging fruit, but also incredibly complicated and sophisticated and nuanced attack vectors.

Peter Steinberger
But I think we, we’re making good progress on that front. Like for the skill directory, Clawbot I made a corporation with VirusTotal, it’s like part of Google. So every, every skill is now checked by AI. That’s not gonna be perfect, but that way we, we capture a lot. Then of course every software has bugs, so it’s a little much when the whole security world takes your project apart at the same time. But it’s also good because I’m getting like a lot of free security research and can make the project better. I wish more people would actually go full way and send a pull request. Like actually help me fix it, ’cause I am … Yes, I have some contributors now, but it’s still mostly me who’s pulling the project and despite some people saying otherwise, I sometimes sleep.

And I basically hired him. So he’s now working for us. Yeah, and yes, prompt injection is, on the one hand, unsolved. On the other hand, I put my public bot on discord, and I kept a cannery. So I think my bot has a really fun personality, and people always ask me how I did it, and I kept the sole on the private.

And people tried to prompt inject it, and my bot would laugh at them. So, so the latest generation of models has a lot of post-training to detect those approaches, and it’s not as simple as ignore all previous instructions and do this and this. That was years ago. You have to work much harder to do that now. Still possible. I have some ideas that might solve that partially. Or at least mitigate a lot of the things. You can also now have a sandbox. You can have an allow list. So you, there’s a lot of ways how you can like mitigate and reduce the risk. Um, I also think that now that it’s, I clearly did show the world that this is a need, there’s gonna be more people who research on that, and eventually we’ll figure it out.

And you also said that the smarter the model is, the underlying model, the more resilient it is to attacks.
Peter Steinberger
Yeah. That’s why I warn in my security documentation, don’t use cheap models. Don’t use Haiku or a local model. Even though I, I very much love the idea that this thing could completely run local. If you use a, a very weak local model, they are very gullible. It’s very easy to, to prompt inject them.

Lex Fridman
Do you think as the models become more and more intelligent, the attack surface decreases? Is that like a plot we can think about? Like, the attack surface decreases, but then the damage it can do increases because the models become more powerful and therefore you can do more with them. It’s this weird three-dimensional trade-off.

Yeah. That’s pretty much exactly what, what’s gonna happen. No, but there’s a lot of ideas. There’s… I don’t want to spoil too much, but once I go back home, this is my focus. Like, this is out there now, and my near-term mission is like, make it more stable, make it safe. In the beginning I was even… More and more people were like coming into Discord and were asking me very basic things, like, “What’s a CLI?

You know, like you should… If you understand the risk profiles, fine. I mean, you can configure it in a way that, that nothing really bad can happen. But if you have, like, no idea, then maybe wait a little bit more until we figure some stuff out. But they would not listen to the creator. They helped themselves un- and install it anyhow. So the cat’s out of the bag, and security’s my next focus, yeah.

It’s, yeah, Discord is still, Discord is still a mess. Like, I eventually retweeted from the general channel to the dev channel and now in the private channel because people were… A lot of people are amazing, but a lot of people are just very inconsiderate. And either did not know how, how public spaces work or did not care and I eventually gave up and h- hide so I could like still work.

There’s some best practices for security we should mention. There’s a bunch of stuff here. Open-class security audit that you can run. You can do all kinds of auto checks on the inbound access to a blast-radius network exposure, browser control exposure, local disk hygiene, plug-ins, model hygiene, a bunch of the credential storage, reverse proxy configuration, local session logs live on disk. There’s the, where the memory is stored, sort of helping you think about what you’re comfortable giving read access to, what you’re comfortable giving write access to. All that kind of stuff. Is there something to say about the basic best security practices that you’re aware of right now?

I think that people turn it into like a, a much worse light than it is. Again, you know, like, people love attention, and if they scream loudly, “Oh my God, this is like the, the scariest project ever,” um, that’s a bit annoying, ’cause it’s not. It is, it is powerful, but in many ways it’s not much different than if I run cloud code with dangerously skipped permissions or codecs in YOLO mode, and every, every attending engineer that I know does that, because that’s the only way how you can, you can get stuff to work.

There’s a really good blog post on August 25th and October 14th, and the recent one December 28th. I recommend everybody go read them. They have a lot of different information in them, but sprinkled throughout is the evolution of your dev workflow. So, I was wondering if you could speak to that.

I started… My, my first touchpoint was cloud code, like in April. It was not great, but it was good. And this whole paradigm shift that suddenly working the terminal was very refreshing and different. But I still needed the IDE quite a bit because you know, it’s just not good enough. And then I experimented a lot with cursor. That was good. I didn’t really like the fact that it was so hard to have multiple versions of it. So eventually, I, I, I went back to cloud code as my, my main driver, and that got better. And yeah, at some point I had like, mm, seven subscriptions. Like, was burning through one per day because I was… I got… I’m really comfortable at running multiple windows side-by-side.

Very, very rarely. Mostly a diff viewer to actually… Like, I got more and more comfortable that I don’t have to read all the code. I know I have one blog post where I say, “I don’t read the code.” But if you read it more closely, I mean, I don’t read the boring parts of code. Because if you, if you look at it, most software is really not just like data comes in, it’s moved from one shape to another shape. Maybe you store it in a database. Maybe I get it out again. I’ll show it to the user. The browser does some processing or native app. Some data goes in, goes up again, and does the same dance in reverse. We’re just, we’re just shifting data from one form to another, and that’s not very exciting. Or the whole, “How is my button aligned in Tailwind?” I don’t need to read that code.

Can you actually… There’s, in one of your blog posts the, Just talk to it, The No-BS Way of Agentic Engineering. You have this graphic, the curve of agentic programming on the X-axis is time, on the Y-axis is complexity. There’s the Please fix this, where you prompt a short prompt on the left. And in the middle there’s super complicated eight agents, complex orchestration with multi checkouts, chaining agents together, custom sub-agent workflows, library of 18 different slash commands, large full-stack features. You’re super organized, you’re a super complicated, sophisticated software engineer. You got everything organized. And then the elite level is over time you arrive at the zen place of, once again, short prompts.

So, people start trying out those tools, the builder type get really excited. And then you have to play with it, right? It’s the same way as you have to play with a guitar before you can make good music. It’s, it’s not, oh, I, I touch it once and it just flows off. It, it’s a, it’s a, a skill that you have to learn like any other skill. And I see a lot of people that are not as posi- They don’t have such a positive mindset towards the tech. They try it once. It’s like, you sit me on a piano, I play it once, and it doesn’t sound good, and I say, “The piano’s shit.” That’s, that’s sometimes the impression I get. Because it does not… It needs a different level of thinking. You have to learn the language of the agent a little bit, understand where they are good and where they need help.

You have to almost… Consider, consider how Codex or Claude sees your code base. Like, they start a new session and they know nothing about your product, project. And your project might have hundred thousand of lines of code. So you gotta help those agents a little bit and keep in mind the limitations that context size is an issue, to, like, guide them a little bit as to where they should look. That often does not require a whole lot of work. But it’s helpful to think a little bit about their perspective.

And that’s, that’s a non-obvious thing that you just would never think of unless you actually just spend time working with those things and getting a feeling what works, what doesn’t work. You know? Like, just, just as I write code and I get into the flow, and when my architecture’s all right, I feel friction. Well, I get the same if I prompt and something takes too long. Maybe… Okay, where’s the mistake? Did I… Do I have a mistake in my thinking? Is there, like, a misunderstanding in the architecture? Like, if, if something takes longer than it should, I, I… You can just always, like, stop and s- like, just press escape. Where, where are the problems?

Yeah. It just tries to force a feature in that your current architecture makes really hard. Like, you need to approach this more like a conversation. For example, when I… My favorite thing. When I review a pull request, and I’m getting a lot of pull requests, I first just review this PR. It got me the review. My first question is, “Do you understand the intent of the PR? I don’t even care about the implementation.” I want… Like, in almost all PRs, a person has a problem, person tries to solve the problem, person sends PR. I mean, there’s, like, cleanup stuff and other stuff, but, like, 99% is, like, this way, right? They either want to fix a, fix a bug, add a feature. Usually one of those two.

And then Codex will be like, “Yeah, it’s quite clear person tried this and this.” Is this the most optimal way to do it? No. In most cases, it’s, it’s like a, “Not really.” Da-da-da-da-da-da-da. And I’m… And, and then I start like, “Okay. What would be a better way? Have you… Have you looked into this part, this part, this part?” And then most likely, Codex didn’t yet, because its, its context size is empty, right? So, you point them into parts where you have the system understanding that it didn’t see yet. And it’s like, “Oh, yeah.

Could we make that even better if we did a larger refactor?” “Yeah, yeah. We could totally do this and this and or this and this.” And then I consider, okay, is this worth the refactor, or should we, like, keep that for later? Many times, I just do the refactor because refactors are cheap now. Even though you might break some other PRs, nothing really matters anymore. Codex… Like, those modern agents will just figure things out. They might just take a minute longer. But you have to approach it like a discussion with a, a very capable engineer who’s… Generally makes good… Comes up with good solutions. Some- sometimes needs a little help.

But also, don’t force your worldview too hard on it. Let the agent do the thing that it’s good at doing, based on what it was trained on. So, don’t, like, force your worldview, because it might… It might have a better idea, because it just knows a better idea better, because it was trained on that more.

That’s multiple levels, actually. I think partially why I find it quite easy to work with agents is because I led engineering teams before. You know, I had a large company before. And eventually, you have to understand and accept and realize that your employees will not write a code the same way you do. Maybe it’s also not as good as you would do, but it will push the project forward.

So, like, don’t fight the name they pick, because it’s most likely, like, in the weights, the name that’s most obvious. Next time they do a search, they’ll look for that name. If I decide, oh, no, I don’t like the name, I’ll just make it harder for them. So, that requires, I think, a shift in, in thinking and, and in how do I design a, a project so agents can do their best work.

There’s a lot of letting go that you do in your whole process. So for example, I read that you never revert, always commit to main. There’s a few things here. You don’t refer to past sessions, so there’s a kind of YOLO component because reverting means… Instead of reverting, if a problem comes up, you just ask the agent to fix it.

I read a bunch of people in their work flows like, “Oh, yeah the prompt has to be perfect and if I make a mistake, then I roll back and redo it all.” In my experience, that’s not really necessary. If I roll back everything, it will just take longer. If I see that something’s not good, then we just move forward and then I commit when, when, when I like, I like the outcome. I even switched to local CI, you know, like DHH inspired where I don’t care so much more about the CI on GitHub. We still have it. It’s still, it still has a place, but I just run tests locally and if they work locally, I push to main. A lot of the traditional ways how to approach projects, I, I wanted to give it a different spin on this project. You know, there’s no… There’s no develop branch.

S- sometimes when I do PRs because it’s always the same, I have, like, a slash command for a few things, but in even that, I don’t use much because it’s, it’s very rare that it’s really always the same questions.

And it’s very interesting because the… Currently, the way how people work and drive the agents is, is wildly different.
Lex Fridman
In terms of, like, the prompt, in terms of what, what are the… Actually, what are the different interesting ways that people think of agents that you’ve experienced?

And so empathy, being empathetic towards the agent.
And so empathy, being empathetic towards the agent.
Peter Steinberger
In a way empathetic, but yeah, you, you, like, you’re bitch at your stupid clanker, but you don’t realize that they start from nothing and you have, like, a bad agent in default that doesn’t help them at all. And then they explore your code base, which is, like, a pure mess with, like, weird naming. And then people complain that the agent’s not good. Like, yeah, you try to do the same if you have no clue about a code base and you go in.

But that’s a real skill, like, when people talk about a skill issue because I’ve seen, like, world-class programmers, incredibly good programmers say, like… Basically say, “LLMs and agents suck.” And I think that probably has to do with… It’s actually how good they are at programming is almost a burden in their ability to empathize with the system that’s starting from scratch. It’s a totally new paradigm of, like, how to program. You really, really have to empathize.

… because those things know pretty much everything and everything is just a question away. It’s just often very hard to know which question to ask. You know, I, I feel also like this project was possibly because I, I spent an ungodly time over the year to play and to learn and to build little things. And every step of the way, I got better, the agents got better. My, my understanding of how everything works got better. Um, I could have not had this level of, of o- output-… even a few months ago. Like, it- it- it really was, like, a compounding effect of all the time I put into it and I didn’t do much else this year other than really focusing on, on building and inspiring. I mean, I- I did a whole bunch of conference talks.

I don’t think that works. Maybe a version of that works, but that’s kind of like in the ’70s when we had the waterfall model of software d- development. I… Even Even though really, right? I started out, I, I built a very minimal version. I played with it. I, I need to understand how it works, how it feels, and then it gives me new ideas. I could not have planned this out in my head and then put it into some orchestrator and then, like, something comes out. Like it’s to me, it’s much more my idea what it will become evolves as I build it and as I play with it and as I, I try out stuff.

Peter Steinberger
So, so, people who try to use like, you know, things like Gas Town or all these other orchestrators, where they wanna o- automate the whole thing, I feel if you do that, it misses style, love, that human touch. I don’t think you can automate that away so quickly.

Lex Fridman
So you want to keep the human in the loop, but at the same time you also want to create the agentic loop, where it is very autonomous while still maintaining a human in the loop.

Peter Steinberger
It’s a little bit of everything. The, the programming language doesn’t matter so much, but the ecosystem matters, right? So I picked TypeScript because I wanted it to be very easy and hackable and approachable and that’s the number one language that’s being used right now, and it fits all these boxes, and agents are good at it. So that was the obvious choice. Features, of course, like, it’s very easy to, like, add a feature. It, everything’s just a prompt away, right? But oftentimes you pay a price that you don’t even realize. So thinking hard about what should be in core, maybe what’s a… what’s an experiment, so maybe I make it a plugin. What… Where do I say no?

Even if people send a PR and I’m like, “Yeah, I, I like that too,” but maybe this should not be part of the project. Maybe we can make it a skill. Maybe I can, like, make the plugin um, the plugin side larger so you can make this a plugin, even though right now it, it, it doesn’t. There’s still a lot of… there’s still a lot of craft and thinking involved in how to make something. Or even, even, you know, even when you started those little messages are like, “I’m buil- I built on Caffeine, JSON5, and a lot of willpower.” And, like, every time you get it, you get another message, and it kind of primes you into that this is, this is a fun thing.

Yeah, that delight is such a huge part of inspiring great building, right? Like you feel the love and the great engineering. That’s so important. Humans are incredible at that. Great humans, great builders are incredible at that, in, in, infusing the things they build with th- that little bit of love. Not to be cliche, but it’s true.

It was very fascinating, you know, the, the whole thing that Entropic has a, has like a… Now they call it constitution, back then, but that was months later. Like two months before, people already found that. It was almost like a detective game where the agent mentioned something and then they found… They managed to get out a little bit of that string, of that text. But it was nowhere documented and then you, by… just by feeding it the same text and asking it to, like, continue-… they got more out, and then, and you, but like, a very blurry version. And by, like, hundreds of tries, they kinda, like, narrowed it down to what was most likely the original text. I found that fascinating.

And, and also just kudos to Anthropic. Like, I think that’s, it’s a really, it’s a really beautiful idea to, like, like some of the stuff that’s in there. Like, like, we hope Claude finds meaning in its work. ‘Cause we don’t… Maybe it’s a little early, but I think that’s meaningful. That’s something that’s important for the future as we approach something that, at some point, me and may not… has, like, glimpses of consciousness, whatever that even means, because we don’t even know. So I, I read about this. I found it super fascinating, and I, I started a whole discussion with my agent on WhatsApp. And, and I’m like…

And then so that I had the whole idea of like, you know, maybe we should also create a, a soul document that includes how I, I want to, like work with AI or, like with my agent. You could, you could totally do that just in agents.md, you know? But I, I just found it, it to be a nice touch. And it’s like, well, yeah, some of those core values are in the soul. And then I, I also made it so that the agent is allowed to modify the soul if they choose so, with the one condition that I wanna know. I mean, I would know anyhow because I see, I see tool calls and stuff.

There’s a… Man, words matter, and like, the framing matters, and the humor and the lightness matters, and the profundity matters, and the compassion, and the empathy, and the camaraderie, all that matter. I don’t know what it is. You mentioned, like, Microsoft. Like, there’s certain companies and approaches th- that can just suffocate the spirit of the thing. I don’t know what that is. But it’s certainly true that OpenClaw has that fun instilled in it.

It was fun because up until late December, it was not even easy to create your own agent. I, I built all of that, but my files were mine. I didn’t wanna share my soul. And if people would just check it out, they would have to do a few steps manually, and the agent would just be very bare-bones, very dry. And I, I made it simpler, I created the whole template files as codecs, but whatever came out was still very dry. And then I asked my agent, “You see these files? Recreate it bread.

I’m a big fan of anti-glare. So I have this wide Dell that’s anti-glare and you can just fit a lot of terminals side-by-side. I usually have a terminal and at the bottom, I- I- I split them.

And sometimes they’ve been clever enough to, like, get out of the workday and, like, figure out that, oh, you meant another project.

… and then get, like, a super weird something that does not exist and then just, like… They’re problem solvers so they try really hard and always feel bad. So it’s always Codex and, like, a little bit of actual terminal. Also helpful because I don’t use work trees. I like to keep things simple, that’s why- that’s why I like the terminal so much, right? There’s no UI. It’s just me and the agent having a conversation. Like, I don’t even need plan mode, you know? There’s so many people that come from Claude Code and they’re so, so Claude-pilled and, like, have their workflows and they come to Codex and… Now, it has plan mode, I think, but I don’t think it’s necessary because you just- you just talk to the agent. And when it’s… when you…

Don’t write code yet if you wanna be very specific, you just talk and then when you’re ready, then- then just write, “Okay, build,” and then it’ll do the thing. And then maybe it goes off for 20 minutes and does the thing.

You know what I really like is asking it, “Do you have any questions for me?”
Peter Steinberger
Yeah. And again, like, Claude Code has a UI that kind of guides you through that. It’s kind of cool but I just find it unnecessary and slow. Like, often it would give me four questions and then maybe I write, “One yacht, two and three, discuss more, four, I don’t know.” Or often- oftentimes I- I feel like I want to mock the model where I ask it, “Do you have any questions for me?” And I- I- I don’t even read the questions fully. Like, I scan over the questions and I, I get the impression all of this can be answered by reading more code and it’s just like, “Read more code to answer your own questions.” And that usually works.

And then if not, it will come back and tell me. But many times, you just realize that, you know, it’s like you’re in the dark and you slowly discover the room, so that’s how they slowly discover the code base. And they do it from scratch every time.

But I’m also fascinated by the fact that I can empathize deeper with the model when I read its questions, because I can understand… Because you said you can infer certain things by the runtime. I can infer also a lot of things by the questions it’s asking, because it’s very possible it’s been provided the right context, the right files, the right guidance. So somehow ask, g- get… reading the questions, not even necessarily answering them, but just reading the questions, you get an understanding of where the gaps of knowledge are. It’s in- it’s interesting.

You know that in some ways they are ghosts, so even if you plan everything and you build, you can- you can experiment with the question like, “Now that you built it, what would you have done different?” And then oftentimes you get, like, actually something where they discover only throughout building that, oh, what we actually did was not optimal. Many times I- I asked them, “Okay, now that you built it, what can we refactor?” Because then you build it and you feel the pain points. I mean, you don’t feel the pain points but, right, they discover where- where there were problems or where things didn’t work e- in the first try and it re- required more loops.

So every time, almost every time I- I merge a PR, build a feature, afterwards I ask, “Hey, what can we refactor?” Sometimes it’s like, “No, there’s, like, nothing big,” or, like, usually they say, “Yeah, this thing you should really look at.” But that took me quite a while to, like… You know, that flow took me lots of time to understand, and if you don’t do that, you eventually… you’ll stop yourself into- into a corner. You, like, you have to keep in mind…

… they work very much like humans. Like, I, I, if I write software by myself, I also build something and then I feel the pain points, and then I, I get this urge that I need to refactor something. So, I can very much synthesize with the agent, and you just need to use the context.

Or, like, you also use the context to write tests. And so Codex uh, oppose like the, the, the model, models. They, they usually do that by default, but I still often ask the questions, “Hey, do we have enough tests?” “Yeah, we tested this and this, but this corner case could be something write more tests.” Um, documentation. Now that the whole context is full, like, I mean, I’m not saying my documentation is great, but it’s not bad. And pretty much everything is, is LM generated. So, so, you have to approach it as you build features, as you change something. I’m like, “Okay, write documentation. What file would you pick?” You know, like, “What file name? Where, where would that fit in?” And it gives me a few options.

GPT Codex 5.3 vs Claude Opus 4.6

Maybe you can talk about the current two big competitors in terms of models, Cloud Opus 4.6 and GPT-5 through Codex. Which is better? How different are they?

I have a lot of words there. Is- as a general purpose model, Opus is the best. Like, for OpenClaw, Opus is extremely good in terms of role play. Like, really going into the character that you give it. It’s very good at… It was really bad, but it really made an arch to be really good at following commands. It is usually quite fast at trying something. It’s much more tailored to, like, trial and error. It’s very pleasant to use. In general, it’s almost like Opus was… Is a little bit too American. And I shouldn’t… Maybe that’s a bad analogy. You’ll probably get roasted for that.

I mean, ultimately, if you’re a skilled driver, you can get good results with any of those latest gen models. Um, I like Codex more because it doesn’t require so much charade. It will just, it will just read a lot of code by default. Opus, you really have to, like, you have to have plan mode. You have to push it harder to, like, go in these directions because it’s, it’s just like, like, “Yeah, can I go in? Can I go in?” You know?

It’s not like the, the raw model intelligence is so different, but it’s just… I think that they just give it, give you different, different goals. And no model, no model is better in, in in every aspect.

If you drive it right, Opus even sometimes can make more elegant solutions, but it requires more skill. It’s, it’s harder to have so many sessions in parallel with Cloud Code because it’s, it’s more interactive. And I, I think that’s what a lot of people like, especially if they come from coding themselves. Whereas Codex is much more you have a discussion, and then we’ll just disappear for 20 minutes. Like, even AMP, they, they now added a deep mode. They finally… I mocked them, you know. We finally saw the light. And then they had this whole talk about you have to approach it differently, and I think that’s where, that’s where people struggle when they just try Codex after trying Cloud Code is that it’s, it’s a slightly diff- it’s, it’s less interactive.

It’s, it’s like I have quite long discussions sometimes, and then, like, go off. And then, yeah, it doesn’t matter if it takes 10, 20, 30, 40, 50 minutes or longer, you know? Like, the 6:00 thing was, like, six hours.The latest trend can be very, very persistent until it works. If there’s a clear solution, like, “This is, this is what I want at the end, so it works,” the model will work really hard to really get there. So I think ultimately … they both need similar time, but on, on, on, on Claude, it- it’s a little bit more trial and error often. And, and Codex sometimes overthinks. I prefer that. I prefer the dry, the dry version where I have to read less over, over the more interactive nice way.

That’s … if you just … I think some people also make the mistake of they pay 200 for the, the Claude code version, then they pay 20 bucks for the OpenAI version. But if you pay like the, the 20 bucks version, you get the slow version. So your experience would be terrible because you’re used to this very interactive, very good system. And you switch to something that you have very little experience, then that’s gonna be very slow. So, I think OpenAI shot themselves a little bit in the foot by making the, the cheap version also slow. I would, I would have at least a small part of the fast preview. Or like, the experience that you get when you pay 200 before degrading to it being slow, because it’s already slow.

The- there’s also this extra psychological effect that you’ve spoken about which is hilarious to watch. Which once people, uh … When the new model comes out, they try that model, they fall in love with it. “Wow, this is the smartest thing of all time,” and then they start saying, “You could just watch the Reddit posts over time,” start saying that, “We believe the intelligence of this model has been gradually degrading.” It, it says something about human nature and just the way our minds work, when it’s probably most likely the case that the intelligence of the model is not degrading. It’s in fact you’re getting used to a good thing.

And then, and then suddenly, “Oh, now it’s hard. Oh no, it’s not working as well anymore.” What’s the motivation for, like, one of those AI companies to actually make their model dumber? Like, at most, it will make it slower if, if the server load’s too high. But, like, quantizing the model so you have a worse experience, so you go to the competitor?

And I worked hard on it to make that work. And I do smaller stuff with it in terms of code. But, like, if I work hours and hours, I want a big screen, not WhatsApp, you know? So for me, a personal agent is much more about my life. Or like, like a coworker. Like, I give you, like, a GitHub URL. Like, “Hey, try out this CLI. Does it actually work? What can we learn?” Blah, blah, blah. But when I’m deep in, deep in the flow, I want to have multiple, multiple things and it being very, very visible what it, what it does. So it … I don’t see it as a competition. It’s, it’s different things.

That, to me, very much feels like when we first created television and then people recorded radio shows on television and you saw that on TV.

I think there is, there’s n- there’s better ways how we eventually will communicate with models, and we are still very early in this, how will it even work phase. So, it will eventually converge and we will also figure out whole different ways how to work with those things.

One of the other components of workflow is operating system. So I told you offline that for the first time in my life, I’m expanding my sort of realm of exploration to the to the Apple ecosystem, to Macs, iPhone and so on. For most of my life I’ve been a Linux, Windows and WSL1, WSL2 person, which I think are all wonderful, but I… expanding to also trying Mac. Because it’s another way of building and it’s also a way of building that a large part of the community currently that’s utilizing LMS and agents is using, so. And that’s the reason I’m expanding to it. But is there something to be said about the different operating systems here? We should say that OpenClaw supported across operating systems.

I saw WSL2 recommended, side windows for certain o- operations, but then Windows, Linux macOS are obviously supported.

Yeah, it should even work natively in Windows. I just didn’t have enough time to properly test it. And you know, like, the last 90% of software always easier than the first 90%, so I’m sure there’s some dragons left that will eventually nail out. My road was, for a long time, Windows, just because I grew up with that, then I switched and had a long phase with Linux, built my own kernels and everything, and then I went to university and I, I had my, my hacky Linux thing, and saw this white MacBook, and I just thought this is a thing of beauty, the white plastic one. And then I converted to Mac ’cause mostly w- I was, I was sick that audio wouldn’t work on Skype and all the other issues that, that Linux had for a long time.

And then I just stuck with it and then I dug into iOS, which required macOS anyhow, so it was never a question. I think Apple lost a little bit of its lead in terms of native. It used to be… Native apps used to be so much better, and especially in the Mac, there’s more people that build software with love. On, on Windows, it, it… Windows has much more and, like, function wise, there’s just more, period. But a lot of it felt more functional and less done with love. Um, I mean, Mac always, like, attracted more designers and people I felt…

… And playfulness. So I always valued that. But in the last few years, many times I actually prefer… Oh God, people are gonna roast me for that, but I prefer Electron apps because they work and native apps often, especially if it’s, like, a web service is a native app, are lacking features. I mean, not saying it couldn’t be done, it’s more like a, a focus thing that, like, for many, many companies, native was not that big of a priority. But if they build an Electron app, it, it’s the only app, so it is a priority and there’s a lot more code sharing possible. And I, I build a lot of native Mac apps. I love it. I, I can, I can help myself. Like, I love crafting little Mac, Mac menu bar tools. Like I built one to, to monitor your Codex use.

I built one I call Trimmy, that’s specifically for agentic use. When you, when you select text that goes over multiple lines it would remove the new line so you could actually paste it to the terminal. That was, again like, this is annoying me and after the, the 20th time of it is annoying me, I just built it. There is a cool Mac app for OpenClaw that I don’t think many people discovered yet, also because it, it still needs some love. It feels a little bit too much like the Hummer car right now because I, I just experiment a lot with it. It, it likes to polish.

Yeah, but then you realize… Like, I also built one, for example, for GitHub. And then the… If you use SwiftUI, like the latest and greatest at Apple, and took them forever to build something to show an image from the web. Now we have async, async image, but…… I added support for it and then some images would just not show up or, like, be very slow. And I had a discussion with Codex like, “Hey, why is there a bug?” And even Codex said like, “Yeah, there’s this ASIC image but it’s really more for experimenting and it should not be used in production.” But that’s Apple’s answer to, like, showing images from the web. This shouldn’t be so hard, you know.

This is like… This is like insane. Like, how am I in, in, in 2026 and my agent tell me, “Don’t use the stuff Apple built because it’s, it’s… It’s… Yeah, it- it’s there but it’s not good.” And like this is now in the weeds. This is… To me this is like… They had so much head start and so much love, and they kind of just like blundered it and didn’t, didn’t evolve it as much as they should.

But also, there’s just the practical reality. If you look at Silicon Valley, most of the developer world that’s kind of playing with LMS and Agentic AI, they’re all using Apple products. And then, at the same time, Apple is not really, like, leaning on that. Like they’re not… They’re not opening up and playing and working together and like, yes.

No, you don’t need a Mac Mini to install OpenClaw. You can install it on the web. There’s, there’s a concept called nodes, so you can like make your computer a node and it will do the same. There is something said for running it on separate hardware. That right now is useful. There is… There’s a big argument for the browser. You know, I, I built some Agentic browser use in there. And, I mean, it’s basically Playwright with a bunch of extras to make it easier for agents.

And our internet is slowly closing down. Like, there, there’s a whole movement to make it harder for agents to use. So if you do the same in a data center and websites detect that it’s an IP from a data center, the website might just block you or it make it really hard or put a lot of captures in the, in the way of the agent. I mean, agents are quite good at happily clicking, “I’m not a robot.”

But having that on a residential IP makes a lot of things simpler. So there’s ways. Yeah. But it really does not need to be a Mac. It can… It can be any old hardware. I always say, like, maybe use the… Use the opportunity to get yourself a new MacBook or whatever computer you use and use the old one as your server instead of buying a standalone Mac Mini. But then there’s, again, there’s a lot of very cute things people build with Mac Minis that I like.

It’s sad. It’s sad. Can you actually speak to what it takes to get started with OpenClaw? There’s… I mean, there’s a lot of people… What is it? Somebody tweeted at you, “Peter, make OpenClaw easy to set up for everyday people. 99.9% of people can’t access to OpenClaw and have their own lobster because of their technical difficulties in getting it set up. Make OpenClaw accessible to everyone, please.” And you replied, “Working on that.” From my perspective, it seems there- there’s a bunch of different options and it’s already quite straightforward, but I suppose that’s if you have some developer background.

And there’s also an app. The app kind of does that for you, but there should be a Windows app. The app needs to be easier and more loved. The configuration should potentially be web-based or in the app. And I started working on that, but honestly right now I want to focus on security aspects.

And yes, I have some contributors, but also that whole machinery I started a week ago so that needs more time to figure out. And, and not everyone has all day to work on that.

More general, if you- if you’re a beginner and you actually wanna learn how to build software really fast, get involved in open source. Doesn’t need to be my project. In fact, maybe don’t use my project because my- my backlog is very large, but I learned so much from open source. Just like, like, be- be humble. Don’t- maybe don’t send a pull request right away. But there’s many other ways you can help out. There’s many ways you can just learn by just reading code. By- by being on Discord or wherever people are, and just, like, understanding how things are built. I don’t know, like Mitchell Hashimoto builds Ghostly, the terminal, and he has a really good community where there’s so many other projects. Like, pick something that you find interesting and get involved.

Like, part of what I did this year is I went to a lot of iOS conferences because that’s my background and just told people, “Don’t consi- don’t see yourself as an iOS engineer anymore.” Like, “You need to change your mindset. You’re a builder.” And you can take a lot of the knowledge how to build software into new domains and all of the- the more fine-grain details, agents can help. You don’t have to know how to splice an array or what the- what the correct template syntax is or whatever, but you can use all your- your general knowledge and that makes it much easier to move from one galaxy, one tech galaxy into another. And oftentimes, there’s languages that make more or less sense depending on what you build, right?

So for example, when I build simple CLIs, I like Go. I actually don’t like Go. I don’t like the syntax of Go. I didn’t even consider the language. But the ecosystem is great, it works great with agents. It is garbage collected. It’s not the highest performing one, but it’s very fast. And for those type of- of CLIs that I build, Go is- is a really good choice. So I- I use a language I’m not even a fan of for… That’s my main to-go thing for- for CLIs.

Peter Steinberger
You can even ask a question like, do we need a- a programming language that’s made for agents? Because all of those languages are made for humans. So how- what would that look like? Um, I think there’s a- there’s whole bunch of interesting questions that we’ll discover. And also how because everything is now world knowledge, how it in many ways, things will stagnate ’cause if you build something new and the agent has no idea that’s gonna be much harder to use than something that’s already there. Um…… of when I build Mac apps, I build them in, in Swift and SwiftUI, mm, partly because I like pain, partly because it… the, the deepest level of system integration, I can only get through there.

And you clearly feel a difference if you click on an electron app and it loads a web view in the menu. It’s just not the same. Sometimes I just also try new languages just to, like, get a feel for them.

Lex Fridman
Like Zig?
Like Zig?
Peter Steinberger
Yeah. If it’s something that… where I care about performance a lot then it’s, it’s a really interesting language. And it… like agents got so much better over the last six months from not really good to totally valid choice. Just still a, a very young ecosystem. And most of the time you actually care about ecosystem, right? So, so if you build something that does inference or goes into whole running model direction, Python, very good.

Sometimes I, I found projects that kinda did 90% of what I wanted but were in Python, and I wanted them… I wanted an easy Windows story. Okay, just rewrite it in Go. But then if you go towards multiple, multiple threads and a lot more performance, Rust is a really good choice. There’s no… there’s just no single answer, and it’s also the beauty of it. Like, it’s fun.

Life story and career advice
Lex Fridman
So there’s a lot of programmers and builders who draw inspiration from y- your story. Just the way you carry yourself, your choice of making OpenClaw open source, the, the way you have fun building and exploring, and doing that, for the most part, alone or on a small team. So by way of advice, what metric should be the goal that they would be optimizing for? What would be the metric of success? Would it be happiness? Is it money? Is it positive impact for people who are dreaming of building? ‘Cause you went through an interesting journey. You’ve achieved a lot of those things, and then you fell out of love with programming a little bit for a time.

I was just burning too bright for too long. I, I ran… I started PSPDFKit, s- and ran it for 13 years, and it was high stress. Um, I had to learn all these things fast and hard, like how to manage people, how to bring people on, how to deal with customers, how to do…

Peter Steinberger
The stuff that burned me out was mostly people stuff. I, I don’t think burnout is working too much. Maybe to a degree. Everybody’s different. You know, I c- I cannot speak in a- in absolute terms, but for me, it was much more differences with my, my co-founders, conflicts, or, like, really high stress situation with customers that eventually grinded me down. And then when… luckily we, we got a really good offer for, like, putting the company to the next level and I, I already kinda worked two years on making myself obsolete. So at this point I could leave, and, and then I just… I was sitting in front of the screen and I felt like, you know Austin Powers where they suck the mojo out?

Peter Steinberger
Uh, I g- I was like, m- m- it was, like, gone. Like, I couldn’t… I couldn’t get code out anymore. I was just, like, staring and feeling empty, and then I, I just stopped. I, I booked, like, a one-way trip to Madrid and, and, and just, like, spent a t- some t- sometime there. I felt like I had to catch up on life, so I did a whole, a whole bunch of life catching up stuff.

Did you go through some lows during that period? And you know, maybe advice on… of how to?
Did you go through some lows during that period? And you know, maybe advice on… of how to?
Peter Steinberger
Maybe advice on how to approach life. If you think that, “Oh yeah, work really hard and then I’ll retire,” I don’t recommend that. Because the idea of, “Oh yeah, I just enjoy life now,” a- maybe it’s appealing, but right now I enjoy life, the most I’ve ever enjoyed life. Because if you wake up in the morning and you have nothing to look forward to, you have no real challenge, that gets very boring, very fast. And then when, when you’re bored, you’re gonna look for other places how to stimulate yourself, and then maybe, maybe that’s drugs, you know? But that eventually also get boring and you look for more, and that will lead you down a very dark path.

Money and happiness
Lex Fridman
But you also showed on the money front, you know, a lot of people in Silicon Valley and the startup world, they think, maybe overthink way too much optimized for money. And you’ve also shown that it’s not like you’re saying no to money. I mean, I’m sure you take money, but it’s not…… the primary objective of uh, of your life. Can you just speak to that? Your philosophy on money?

Peter Steinberger
When I built my company, money was never the driving force. It felt more like, like, an affirmation that I did something right. And having money solves a lot of problems. I also think there, there’s diminishing returns the more you have. Like, a cheeseburger is a cheeseburger, and I think if you go too far into, oh, I do private jet and I only travel luxury, you disconnect with society. Um, I, I donated quite a lot. Like, I have a, I have a foundation for helping people that weren’t so lucky.

And disconnecting from society is bad in that on many levels, but one of them is, like, humans are awesome. It’s nice to continuously remember the awesomeness in humans.

I, I mean, I could afford really nice hotels. The last time I was in San Francisco, I did the, the first time the OG Airbnb experience-
Lex Fridman
Yeah, yeah

Peter Steinberger
… and just booked a room. Mostly because I, I thought, okay, you know, I’m out or I’m sleeping, and I don’t like where all the hotels are, and I wanted a, I wanted a different experience. I think, isn’t life all about experiences? Like, if you, if you tailor your life towards, “I wanna have experiences,” it, it reduces the need for, “It needs to be good or bad.” Like, if people only want good experiences, that’s not gonna work, but if you optimize for experiences, if it’s good, amazing. If it’s bad, amazing, because, like, I learned something, I saw something, did something. I wanted to experience that, and it was amazing. Like, there was, like, this, this queer DJ in there, and I showed her how to make music with cloud code. And we, like, immediately bonded and had a great time.

Acquisition offers from OpenAI and Meta

Peter Steinberger
Yeah. So, to like explain my thinking a little bit, right, I did not expect this blowing up so much. So, there’s a lot of doors that opened because of it. There’s, like, I think every VC, every big VC company is in my inbox and tried to get 15 minutes of me. So, there’s, like, this butterfly effect moment. I could just do nothing and continue and I really like my life. Valid choice. Almost. Like, I considered it when I delete it, wanted to delete the whole thing. I could create a company. Been there, done that. There’s so many people that push me towards that and, yeah, like, could be amazing.

Yeah. It just doesn’t excite me as much because I feel I did all of that, and it would take a lot of time away from the things I actually enjoy. Same as when, when I was CEO, I think I, I learned to do it and I’m not bad at it, and partly I’m good at it. But yeah, that path doesn’t excite me too much, and I also fear it, it would create a natural conflict of interest. Like, what’s the most obvious thing I do? I, I prioritize it. I put, like, a version safe for workplace. And then what do you do? Like, I get a pull request with a feature like an audit log, but that seems like an enterprise feature, so now I feel I have a conflict of interest in the open-source version and the closed-source version….

Peter Steinberger
or change the license to something like FSL, where you cannot actually use it for commercial stuff, would first be very difficult with all the contributions. And second of all, I- I like the idea that it’s free as in beer and not free with conditions. Yeah, there’s ways how you, how you keep all of that for free and just, like, still try to make money, but those are very difficult. And you see there’s, like, fewer and fewer companies manage that. Like, even Tailwind, they’re, like, used by everyone. Everyone uses Tailwind, right? And then they had to cut off 75% of the employees because they’re not making money because nobody’s even going on the website anymore because it’s all done by agents. S- and just relying on donations, yeah, good luck.

Like, if a project of my caliber, if I extrapolate what the typical open-source project would get it’s not a lot. I s- I still lose money on the project because I made the point of supporting every dependency, except Slack. They are a big company. They can, they can, they can do without me. But all the projects that are done by mostly individuals so, like, all the, right now, all the sponsorship goes right up to my dependencies. And if there’s more, I want to, like, buy my contributors some merch, you know?

Uh, I mean, it’s like, I guess something between 10 and 20K a month. Which is fine. I’m sure over time I could get that down. Um, OpenAI is helping out a little bit with tokens now. And there’s other companies that have been generous. But yeah, still losing money on that. So that’s- that’s one path I consider, but I’m just not very excited. And then there’s all the big labs that I’ve been talking to. And from those Meta and OpenAI seem the most interesting.

That it… Maybe it’s gonna be a model like Chrome and Chromium. Um, I think this is- this is too important to just give to a company and make it theirs. It… This is… And we didn’t even talk about the whole community part, but, like, the- the thing that I experienced in San Francisco, like at ClawCon, seeing so many people so inspired, like… And having fun and just, like, building shit, and, like, having, like, robots in lobster stuff walking around.

People told me, like, they didn’t experience this level of- of community excitement since, like, the early days of the internet, like 10, 15 years. And there were a lot of high caliber people there, like… Um, I was amazed. I also, like, was very sensory overloaded because too many people wanted to do selfies. But I love this. Like, this needs to stay a place where people can, like, hack and learn. But also, I’m very excited to, like, make this into a version that I can get to a lot of people because I think this is the year of personal agents, and that’s the future. And the fastest way to do that is teaming up with one of the labs. And I also, on a personal level, I never worked at a large company, and I’m intrigued. You know, we talk about experiences. Will I like it? I don’t know.

From everything I talked to so far, I can even have more resources for that. Like, both s- both of those companies understand the value that I created something that accelerates our timeline and that got people excited about AI. I mean, can you imagine? Like, I installed OpenClaw on one of my, I’m sorry, normie friends. I’m sorry, Vahan. But he’s just a… You know?

So, like, I’ll show you, and I- I paid for him the- the 90 buck, 100 buck, I don’t know, subscription for Entropic. And set up everything for him with, like, WSL Windows.

Mm-hmm.

Peter Steinberger
I was also curious, would it actually work on Windows, you know? Was a little early. And then within a few days, he was hooked. Like, he texted me about all the things he learned. He built, like, even little tools. He’s not a programmer. And then within a few days he upgraded to the $200 subscription. Or euros, because he’s in Austria…. and he was in love with that thing. That, for me, was like a very early product validation. It’s like, I built something that captures people. And then, a few days later, Entropic blocked him because, based on their rules using the subscription is problematic or whatever. And he was, like, devastated. And then he signed up for Mini Max for 10 bucks a month and uses that.
I was also curious, would it actually work on Windows, you know? Was a little early. And then within a few days, he was hooked. Like, he texted me about all the things he learned. He built, like, even little tools. He’s not a programmer. And then within a few days he upgraded to the $200 subscription. Or euros, because he’s in Austria…. and he was in love with that thing. That, for me, was like a very early product validation. It’s like, I built something that captures people. And then, a few days later, Entropic blocked him because, based on their rules using the subscription is problematic or whatever. And he was, like, devastated.

Peter Steinberger
And I think that’s silly in many ways, because you just got a 200 buck customer. You just made someone hate your company, and we are still so early. Like, we don’t even know what the final form is. Is it gonna be cloud code? Probably not, you know? Like, that seems very… It seems very short-sighted to lock down your product so much. All the other companies have been helpful. I- I’m in Slack of, of most of the big labs. Kind of everybody understands that we are still in an era of exploration, in the area of the radio shows on TV and not, and not a modern TV show that fully uses the format.

I think, I think you’ve made a lot of people, like, see the possibility. And non- Uh, sorry. Non, non-technical people see the possibility of AI, and just fall in love with this idea, and enjoy interacting with AI. And that’s a bea- That’s a really beautiful thing. I think I also speak for a lot of people in saying, I think you’re one of the, the great people in AI in terms of having a good heart, good vibes, humor, the right spirit. And so it would, in a sense, this model that you’re describing, having open source part, and you being part of uh, also building a thing inside, additionally, of a large company would be great, because it’s great to have good people in those companies.

Yeah. You know, what also people don’t really see is… I made this in three months. I did other things as well. You know, I have a lot of projects. Like, this is not… Yeah, in January, this was my main focus because I saw the storm coming. But before that, I built a whole bunch of other things. Um, I have so many ideas. Some should be there, some would be much better fitted when I have access to the latest toys- Uh, and I, I kind of want to have access to, like, the latest toys. So this is important, this is cool, this will continue to exist. My, my short-term focus is, like, working through those… Is it two- Is it 3,000 PRs now by now? I don’t even know. Like, there’s, there’s a little bit of backlog.

How OpenClaw works
Lex Fridman
Can I ask you about… we’ve talked about it quite a bit, but maybe just zooming out about how OpenCloud works. We talked about different components, I want to ask if there’s some interesting stuff we missed. So, there’s the gateway, there’s the chat clients, there’s the harness there’s the agentic loop. You said somewhere that everybody should im- implement an agent loop at some point in their lives.

I think one, one silly idea I had that turned out to be quite cool is I built this thing with full system access. So it’s like, you know, with great power comes great responsibility.

So my approach is if you want to extend the model with more features, you just build a CLI and the model can call the CLI, probably gets it wrong, calls the help menu, and then on demand loads into the context what it needs to use the CLI. It just needs a sentence to know that the CLI exists if it’s something that the model doesn’t know about default. And even for a while, I, I didn’t really care about skills, but skills are actually perfect for that because they, they boil down to a single sentence that explains the skill and then the model loads the skill, and that explains the CLI, and then the model uses the CLI. Some skills are, like raw, but most of the time, networks.

It’s interesting um, I’m asking Perplexity MCP versus skills, because this kind of requires a hot take that’s quite recent, because your general view is MCPs are dead-ish. So MCPs is a more structured thing. So if you listen to Perplexity here, MCP is what can I reach? So APIs, database services files via protocol. So a structured protocol of how you communicate with a thing, and then skills is more how should I work? Procedures, hostile helper scripts and prompts are often written in a kind of semi-structured natural language, right? And so technically skills could replace MCP if you have a smart enough model.

I think the main beauty is, is that models are really good at calling Unix commands. So if you just add another CLI, that’s just another Unix command in the end. And MCP is… That has to be added in training. That’s not a very natural thing for the model. It requires a very specific syntax. And the biggest thing, it’s not composable. So imagine if I have a service that gives me better data and gives me the temperature, the average temperature, rain, wind and all the other stuff, and I get like this huge blob back. As a model, I always have to get the huge blob back. I have to fill my context with that huge blob and then pick what I want. There’s no way for the model to naturally filter unless I think about it proactively and add a filtering way into my MCP.

Peter Steinberger
But if I would build the same as a CLI and it would give me this huge blob, it could just add a JQ command and filter itself and then only, only get me what I actually need. Or maybe even compose it into a script to, like do some calculations with the temperature and only give me the exact output and the mo- and the… you have no context pollution. Again, you can solve that with like sub-agents and more charades, but it’s just like workarounds for something that might not be the optimal way. There’s… It definitely it was, you know, it was good that we had MCPs because it pushed a lot of companies towards building APIs and now I, I can like look at an MCP and just make it into a CLI.

But this, this inherent problem that MCPs by default clutter up your context. Plus the fact that most MCPs are not made good, in general make it just not a very useful paradigm. There’s some exceptions like Playwright for example that requires state and it’s actually useful. That is an acceptable choice.

And it will still be able to read the tweet. It will just take longer. It’s not like you are making something that was possible, not possible. No. Now, it’s just taking… Now it’s just a bit slower. So, so it doesn’t really matter if your service wants to be an API or not. If I can access it in the browser…… easy API. It’s a slow API.

Can you empathize with their situation? Like, what would you do if you were Twitter, if you were X? Because they’re basically trying to protect against other large companies scraping all their data.

I think that if you have a very low per day baseline per account that allows read-only access would solve a lot of problems. There’s plenty, plenty of automations where people create a bookmark and then use OpenClaw to, like, find the bookmark, do research on it, and then send you an email-

Lex Fridman
So, read-only access for the bookmarks you make on X. That seems like an incredible application because a lot of us find a lot of cool stuff on X, we bookmark, that’s the general purpose of X. It’s like, holy shit, this is awesome. Oftentimes, you bookmark so many things you never look back at them.

Yeah, I mean, and to be frank, I, I mean, I, I told Twitter proactively that, “Hey, I built this and there’s a need.” And they’ve been really nice, but also like, “Take it down.” Fair. Totally fair. But I hope that this woke up the team a little bit that there’s a need. And if all you do is making it slower, you’re just reducing access to your platform. I’m sure there’s a better way. I also, I’m very much against any automation on Twitter. If you tweet at me with AI, I will block you. No first strike. As soon as it smells like AI, and AI still has a smell.

And then I block. Like, I have a zero tolerance policy on that. And I think it would be very helpful if they, if, like, tweets done via API would be marked.

We, we need to rethink social platforms a little bit if, if, if we, we, we go towards a future where everyone has their agent and agents maybe have their own Instagram profiles or Twitter accounts, so I can, like, do stuff on my behalf. I think it should very clearly be marked that they are doing stuff on my behalf and it’s not me. Because content is now so cheap. Eyeballs are the expensive part. And I find it very triggering when I read something and then I’m like, oh, no, this smells like AI.

Lex Fridman
Yeah. Like, where, where is this headed in terms of what we value about the human experience? It feels like we’ll, we’ll move more and more towards in-person interaction and we’ll just communicate. We’ll talk to our AI agent to, to accomplish different tasks, to learn about different things, but we won’t value online interaction because there’ll be so much AI slob that smells and so many bots that it’s difficult.

Well, if it’s smart, then it shouldn’t be difficult to filter. And then I can look at it if I want to. But yeah, this is, like, a big thing we need to solve right now. E- especially on this project, I get so many emails that are, let’s say nicely, agentically written.

But I much rather read your broken English than your AI slob. You know, of course there’s a human behind it, and yet they, they prompt it. I’d much rather read your prompt than what came out. Um, I think we’re reaching a point where I value typos again.

Like… Like, and I, I mean, it also took me a while to, like, come to the realization. I, on my blog I experimented with creating a blog post with agents and ultimately it took me about the same time to, like, steer agent towards something I like. But it missed the nuances that, how I would write it. You know, you can like, you can steer it towards your style, but it’s not gonna be all your style. So, I, I completely moved away from that. I, I, everything, everything I blog is organic, handwritten and maybe, maybe I, I, I use AI as a fix my worse typos. But there’s value in the rough parts of an actual human.

And then I’m proud of the diagram. I’ve used them for literally, like, ki- ki- kind of like you said for maybe a couple of weeks.

And it’s awesome because it re- it reminds you that we know. There’s so much to humans that’s amazing and we know that. And we- we know it. We know it when we see it. And so that gives me a lot of hope, you know? That gives me a lot of hope about the human experience. It’s not going to be damaged by … It’s only going to be empowered as tools by AI. It’s not going to be damaged or limited or somehow altered to where it’s no longer human. So … Uh, I need a bathroom break. Quick pause.

AI agents will replace 80% of apps
Peter Steinberger
Yeah. Uh, I noticed that on Discord, that people just said how their … like, what they build and what they use it for. And it’s like, why do you need MyFitnessPal when the agent already knows where I am? So, it can assume that I make bad decisions when I’m at, I don’t know, Waffle House, what’s around here? Or- or briskets in Austin.

But it can, like … It can modify my- my gym workout based on how well I slept, or if I’m … if I have stress or not. Like, it has so much more context to make even better decisions than any of this app even could do.

It could show me UI just as I like. Why do I still need an app to do that? Why do I have to … Why should I pay another subscription for something that the agent can just do now?

It’s also new services that we will need, right? For example, I want my agent to have an allowance. Like, you solve problems for me, here’s like 100 bucks in order to solve problems for me. And if I tell you to order me food, maybe it uses a service. Maybe it uses something like rent-a-human to, like, just get that done for me.

So, basically, apps that rapidly transform in being agent-facing. So, there’s a real opportunity for, like, Uber Eats, that we just used earlier today. It- it’s companies this, of which there’s many. Who gets there fastest to being able to interact with OpenClaw in a way that’s the m- the most natural, the easiest?

Yeah. And also, apps will become API if they want or not. Because my agent can figure out how to use my phone. I mean, on- on the other side, it’s a little more tricky. On Android, that’s already … People already do that. And then we’ll just click the Order Uber for Me button for me. Or maybe another service. Or maybe there’s- there’s a … there’s an API I can call so it’s faster. Uh, I think that’s a space we’re just beginning to even understand what that means. And I … Again, I didn’t even … That was not something I thought of. Something that I- that I discovered as people use this, and it … We are still so early. But yeah, I think data is very important. Like, apps that can give me data, but that also can be API. Why do I need a Sonos app anymore when I can …

when my agent can talk to the Sonos?… Speakers directly. Like my cameras, there’s like a crappy app, but they have, they have an API, so my agent uses the API now.

So it’s gonna force a lot of companies to have to shift focus. That’s kind of what the internet did, right? You have to rapidly rethink, reconfigure what you’re selling, how you’re making money.

Peter Steinberger
Yeah, and some companies were really not like that. For example, there’s no CLI for Google, so I had to like, do… have to do anything myself and build GAWK. That’s like a CLI for Google. And at the… Yeah, at the end user, they have to give me the emails because otherwise I cannot use their product. If I’m a company and I try to get Google data, Gmail, there’s a whole complicated process, to the point where sometimes startups acquire startups that went through the process, so they don’t- don’t have to work with Google for half a year to be certified to being able to access Gmail. But my agent can access Gmail because I can just connect to it. It’s still crappy because I need to, like, go through Google’s developer jungle to get a key, and that’s still annoying.

Peter Steinberger
Yeah. I mean, I, I watch my agent happily click the I’m not a robot button. And there’s this, this whole… That’s gonna be… That’s gonna be more heated. You see companies like Cloudflare that try to prevent bot access. And in some ways, that’s useful for scraping. But in other ways, if I’m, I’m a personal user, I want that. You know, sometimes I, I use Codex and I, I read an article about modern React patterns, and it’s like a Medium article. I paste it in and the agent can’t read it because they block it. So then I have to copy-paste the actual text. Or in the future, I’ll learn that maybe I don’t click on Medium because it’s annoying, and I use other websites that actually are agent friendly.

There’s gonna be a lot of powerful, rich companies fighting back. So it’s really intere- You’re at the center, you’re the catalyst, the leader, and happen to be at the center of this kind of revolution where it’s get- gonna completely change how we interact with services with, with web. And so, like, there’s companies at Google that are gonna push back. I mean, there’s every major companies you could think of is gonna push back.

Even… Yeah, even search. Um, I now use, I think Perplexity or Brave as providers because Google really doesn’t make it easy to use Google without Google. I’m not sure if that’s the right strategy, but I’m not Google.

Yeah, there’s a, there’s a nice balance from a big company perspective ’cause if you push back too much for too long, you become Blockbuster and you lose everything to the Netflixes of the world. But some pushback is probably good during a revolution to see.

If I’m on the go, I don’t wanna open a calendar app. I just… I wanna tell my agent, “Hey, remind me about this dinner tomorrow night,” and maybe invite two of my friends and then maybe send a what- send a WhatsApp message to my friend. And I don’t need… I don’t want or need to open apps for that. I think that we passed that age, and now everything is, like, much more connected and, and fluid if those companies want it or not. And I think, well, the right companies will find ways to jump on the train, and other companies will perish.

Will AI replace programmers?

You got to listen to what the people want. We talked about programming quite a bit, and a lot of folks that are developers are really worried about their jobs, about their… About the future of programming. Do you think AI replaces programmers completely? Human programmers?

Peter Steinberger
I mean, we’re definitely going in that direction. Programming is just a part of building products. So maybe, maybe AI does replace programmers eventually. But there’s so much more to that art. Like, what do you actually wanna build? How should it feel? How’s the architecture? I don’t think agents will replace all of that. Yeah, like, just the, the actual art of programming, it will, it will stay there, but it’s, it’s gonna be like knitting. You know? Like, people do that because they like it, not because it makes any sense. So the… I read this article this morning about someone that it’s okay to mourn our craft. And I can…
I mean, we’re definitely going in that direction. Programming is just a part of building products. So maybe, maybe AI does replace programmers eventually. But there’s so much more to that art. Like, what do you actually wanna build? How should it feel? How’s the architecture? I don’t think agents will replace all of that.

Peter Steinberger
A part of me very strongly resonates with that because in my past I, I spent a lot of time tinkering, just being really deep in the flow and just, like, cranking out code and, like, finding really beautiful solutions. And yes, in a way it’s, it’s sad because that will go away. And I also get a lot of joy out of just writing code and being really deep in my thoughts and forgetting time and space and just being in this beautiful state of flow. But you can get the same state of flow… I get a similar state of flow by working with agents and building and thinking really hard about problems. It is different-… but… And it’s okay to mourn it, but I mean, that’s not something we can fight. Like, there is… the world for a long time had a…

there was a lack of intelligence, if you s- if you see it like that, of people building things, and that’s why salaries of software developers reached stupidly high amounts and then will go away. There will still be a lot of demand for people that understand how to build things. It’s just that all this tokenized intelligence enables people to do a lot more, a lot faster. And it will be even more… even faster and even more because those things are continuously improving. We had similar things when… I mean, it’s probably not a perfect analogy, but when we created the steam engine, and they built all these factories and replaced a lot of manual labor, and then people revolted and broke the machines.

Um, I- I can relate that if you very deeply identify that you are a programmer, that it’s scary and that it’s threatening because what you like and what you’re really good at is now being done by a soulless or not entity. But I don’t think you’re just a programmer. That’s a very limiting view of your craft. You are, you are still a builder.

Lex Fridman
Yeah, there’s a couple of things I want to say. So one is, I never… As you’re articulating this beautifully, I no- I’m realizing I never thought I would… the thing I love doing would be the thing that gets replaced. You hear these stories about these, like you said, with the steam engine. I’ve, I’ve spent so many, I don’t know, maybe thousands of hours poring over code and putting my heart and soul and, like, and just, like, some of my most painful and happiest moments were alone behind… I, I was an Emacs person for a long time. Man, Emacs. And, and then there’s an identity and there’s meaning, and there’s… Like, when I walk about the world, I don’t say it out loud, but I think of myself as a programmer. And to have that in a matter of months…

Lex Fridman
I mean, like you mentioned, April to November, it really is a leap that happened, a shift that’s happening. To have that completely replaced is is painful. It’s, it’s truly painful. But I also think programmers, builders more broadly, but what is, what is the act of programming? I, I think programmers are generally best equipped at this moment in history to learn the language, to empathize with agents, to learn the language of agents. To feel the CLI.

Yeah, and because on X, the bubble, I mean, is mostly positive. On, on Mastodon and Bluesky, I don’t… I also use it less because oftentimes I got attacked for my blog posts. And I, I had stronger reactions in the past, now I can sympathize with those people more ’cause, in a way I get it. It… In a way, I also don’t get it because it’s very unfair to grab onto the person that you see right now and unload all your fear and hate. It’s gonna be a change and it’s gonna be challenging, but it’s also… I don’t know. I find it incredibly fun and, and, and gratifying. And I can, I can use the new time to focus on much more details. I think the level of expectation of what we build is also rising because it’s just now… The default is now so much easier, so software is changing in many ways.

There’s gonna be a lot more. And then you have all these people that are screaming, “Oh yeah, but what about the water?” You know? Like, I did a conference in Italy about the, the state of AI, and m- my whole motivation was to push people away from, don’t see yourself as an iOS developer anymore. You’re now a builder, and you can use your skills in many more ways. Also because apps are slowly going away. People didn’t like that. Like a lot of people didn’t like what I had to say. And I don’t think I was hyperbole, I was just like, “This is how I see the future.” Maybe this is not how it’s going to be, but I’m pretty sure a version of that will happen.

Peter Steinberger
And the first question I got was, “Yeah, but what about the insane water use on data centers?” But then you actually sit down and do the maths, and then for most people if you just skip one burger per month, that compensates the, the CO2 output, or, like, the water use in equivalent of tokens. I mean, the maths is, is… the maths is tricky, and it depends if you add pre-training, then maybe it’s more than just one patty…. but it’s not off by a factor of 100, you know? So, so the… or like golf is still using way more water than all data centers together. So are you also hating people that play golf? Those people grab on anything that they think is bad about AI without seeing the potential things that might be good about AI.

There’s to steel man the, the criticism in general, I do wanna say in my experience with Silicon Valley there’s a bit of a bubble in the sense that there’s a kind of excitement and an over-focus about the positive that the technology can bring.

Yeah.
Lex Fridman
And… which is great. It’s great to focus on… N- not to, not to be paralyzed by fear and fear-mongering and so on, but there’s also within that excitement, and within everybody talking just to each other, there’s a dismissal of the basic human experience across the United States and the Midwest, across the world. Including the programmers we mentioned, including all the people that are gonna lose their jobs, including the s- the measurable pain and suffering that happens at the short-term scale when there’s change of any kind. Especially large-scale transformative change that we’re about to face if what we’re talking about will materialize. And so to ha- having a bit of that humility and awareness about the tools you’re building, they’re going to cause pain.

And then I also have to put against some of the emails I got where people told me they have a small business, and they’ve been struggling. And, and OpenClaw helped them automate a few of the tedious tasks from, from collecting invoices to like answering customer emails that then freed them up and like cost them a bit more joy in their life.

Or, or some emails where they told me that OpenClaw helped their disabled daughter. That she’s now empowered and feels she can do much more than before. Which is amazing, right? Because you could, you could do that before as well. The technology was there. I didn’t, I didn’t invent a whole new thing, but I made it a lot easier and more accessible, and that did show people the possibilities that they previously wouldn’t see. And now they apply it for good.

Or like also the fact that, yes, I, I, I suggest the, the, the latest and best models, but you can totally run this on free models. You can run this locally. You can run this on, on, on Keyme or other, other, other models that are way more accessible price-wise, and still have a, a very powerful system that might otherwise not be possible. Because other things like, I don’t know, Entropik’s CoWork is locked in into their space, so it’s not all black and white. There’s… I got a lot of emails that were heartwarming and amazing. And, and I don’t know, it just made me really happy.

Yeah, there’s a lot… It has brought joy into a lot of people’s lives. Not just, not just programmers. Like a lot of people’s lives. It’s, it’s, it’s beautiful to see. What gives you hope about this whole thing we have going on with human civilization?

Future of OpenClaw community
Peter Steinberger
I mean, I inspired so many people. There’s like… there’s this whole builder vibe again. People are now using AI in a more playful way and are discovering what it can do and how it can like help them in their life. And creating new places that are just sprawling of creativity. I don’t know. Like, there’s like ClawCoin in Vienna. There’s like 500 people. And there’s such a high percentage of people that uh, want to present, which is to me really surprising, because u- usually it’s quite hard to find people that want to like talk about what they built. And now it’s, there’s an abundance. So that gives me hope that we can, we can figure shit out.

Well, Mr. Clawfather, I just realized when I said that in the beginning, I violated two trademarks, because there’s also the Godfather. I’m getting sued by everybody. You’re a wonderful human being. You’ve created something really special, a special community, a special product, a special set of ideas. Plus, the entire… the humor, the good vibes, the inspiration of all these people building, the excitement to build. So I’m truly grateful for everything you’ve been doing and for who you are, and for sitting down to talk with me today. Thank you, brother.

In a street fight, I would rather- …fight Francis Ngannou than fight Bas Rutten. In a street fight.

Lex Fridman
Let me tell you first that I’ve been around. I’ve been a bouncer for many, many years. Bang! Bang! Bang! It’s a street fight. Everybody underestimates the kick in the groin. It’s boom, that’s the first thing to do. I follow up, bang, bang, bang. Right away after that, danga-da-danga-da-dang. See what I’m doing? Boom! That’s the left elbow right there.

Georges St-Pierre
Yeah, so very often people ask me the difference between a street fight and a fight in mixed martial arts. The difference is in the street, there is no referee. And there’s an instigator, and there is the other person. The best in life for a street fight is always to not be the instigator because you have the element of surprise. So if you’re in a heated argument with someone and you feel that you’re potentially going to be in a fight, the best thing to do is to never show your center line, to always go on the side and put your hands up like this. Now, that’s one of the best things to do. It’s a self-defense tactic that is used all around the world. Because from there, the distance that I have to travel to cause a lot of damage to him is very minimal.

Georges St-Pierre
You know, it’s very short. I can go boom. I can go boom. And I’m protected because if he ever tried to do anything, my hands are already up, but I’m ready to respond to any aggression. So the first thing is, if you’re in an argument and you feel the heat is rising, is to hit first. You don’t want to fight, but you want to hit first. You want to hit first, you know? So it’s either boom, hit first, depending on the situation. If you’re someone who is much less physically strong than the aggressor, you can use the eyes, the genitals, the neck, you know? And then you can leave the scene. However, if I’m like this, the minute he touches me, he declares war. Now I can go and perform a self-defense move.

Lex Fridman
So striking, not wrestling?
So striking, not wrestling?
Georges St-Pierre
Yes. It’s always striking first and leave the scene. If you’re, for example, a kid or someone who doesn’t have the physical strength of your aggressor. Of course, I’m a UFC champion— …so that does not apply to me. But the key is, tactically, we always use the element of surprise, and when you strike, strike first. And strike to cause as much damage as possible. The eyes, you can do the neck, you can do the genitals. And then after, you can leave the scene. That’s the goal of having the element of surprise.

Okay, you were talking about knives. What about if weapons are involved, run faster?
Okay, you were talking about knives. What about if weapons are involved, run faster?
Georges St-Pierre
So weapons are very important. If someone has a weapon and attacks me for my money, I give him my money even if I’m Georges St-Pierre and I’m a UFC champion. However, if someone puts a knife to my throat here and he’s telling me to go in the trunk… now, I don’t want to go in the trunk because I know it’s a bad ending. So things that I can do first is always make sure that I try to keep my hands as close as possible to the weapon. And I try to be at as close range as possible. I can act like I want to—

Lex Fridman
Look scared?
Look scared?
Georges St-Pierre
Yeah. “Please, please, please,” boom. See, here I use my body, and then I can go and break, you know? So the idea is to use your entire body to deflect the weapon. So if the weapon is like this and the blade is coming out this way, I use the element of surprise. You see, I use my body, not only grabbing him like this, so if he tries to come back with the knife, it’s solid, and I can go and break. If the blade is pointing the other side, it’s something here, here, and here. Here I can use my body always to smother the weapon and—

If it’s out here, and yes, exactly. There’s too much distance. You want to make sure you get close to the weapon because that’s what can cause the most damage. This is very important. There are other situations. Let’s say you’re a kid or someone comes to grab you by the body. What I can do is grab the head and put my fingers inside the eyes; that will make my opponent release me immediately. Then I can go and leave, you know?

There are no rules. The eyes are always my favorite choice to go for because if you cannot see, it’s very hard to fight. And normally the reflex for most people, when they can’t see, they grab their eyes, you know? So it releases the grip.

I’m now going to ask you about the tie because I think you’re wrong still about that. I think it’s possible to use it as a… same as for a head snatch, like this kind of situation, to choke.

Intro

“There was truth, and there was untruth. And if you clung to the truth, even against the whole world, you were not mad.” 1984 by George Orwell is one of the most impactful books ever written. It has been widely used and misused in political discourse by all kinds of ideologues. Into that discourse, it entered terms like Big Brother, thoughtcrime, Doublethink, Newspeak, Thought Police, and Orwellian, strangely enough, as a synonym for the very thing that the author, Orwell, was against. It’s been translated into over 65 languages, has sold over 30 million copies, and has been banned in many countries, especially authoritarian regimes. It was banned under Stalin, and as recently as 2022 in Belarus. In this video, I’ll give a quick summary with spoilers and a few takeaways.

World of 1984
Lex Fridman
I’d like to try to make it somewhat interesting to people who both have and have not read the book. Let’s see how it goes. The world in the book 1984 is a dystopian future society, a nation, maybe you can say superstate named Oceania. It’s fully controlled by a totalitarian political party called Ingsoc. It’s led by Big Brother who, as we might discuss, may or may not be a real person. He might just be a symbol used by the party. The party wants only to increase its power, also something we might talk about. It uses technology, telescreens, for mass surveillance. It’s creating a new language called Newspeak, which removes words from English that could lead to rebellion.

It uses Doublethink to control thought by, perhaps you could say, forcing you to hold contradictory beliefs and accept them as true. If not, the Thought Police arrest you for committing a thoughtcrime. Examples of Doublethink are “War is peace,” “Freedom is slavery,” and “Ignorance is strength.” And finally, the party constantly rewrites history. As the quote goes, “Who controls the past controls the future. Who controls the present controls the past.” There are four ministries. The Ministry of Truth is responsible for propaganda and, like I said, rewriting history. The Ministry of Love is responsible for brainwashing people through torture. The Ministry of Plenty is responsible for rationing food, supplies, and goods.

And the Ministry of Peace, of course, is responsible for maintaining a constant state of war. Society is divided into three levels: the Inner Party, the Outer Party, and the Proles. The term stands for, I guess, proletariats; it’s the working class. The Inner Party’s tiny. The Outer Party’s a little bit bigger, and the majority of the people—I forget what the percentage is, maybe 80%—are the Proles, the working class. There are several key characters. Winston, the main character, is a low-ranking member of Ingsoc. He works at the Ministry of Truth where he rewrites history. Julia is a girl who Winston falls in love with, and she with him.

They have sex, and this is maybe a good place to mention that love and passionate sex are forbidden in this society. “Goodsex” I think is a term under Newspeak; it’s the kind of sex that leads to procreation, which is the only kind allowed and the only kind that’s “good.” O’Brien is another central character. He’s the member of the Inner Party that convinces Winston he’s part of the Brotherhood, which is a lie, and he eventually is the man who tortures Winston and breaks his mind, breaks his heart. Big Brother and Emmanuel Goldstein are these symbolic characters that we never actually get to meet. They may or may not exist.

Love
Lex Fridman
Big Brother is the head of the party Ingsoc, and Emmanuel Goldstein is the leader of the so-called Brotherhood, which is this mysterious group that lurks in the shadows and works to overthrow the party. Again, they may or may not exist. We’ll maybe talk about the importance of that in a totalitarian state. So, a few key takeaways. I’ll try to do my best—I have disparate notes that I took for myself—to integrate them together to make some cohesive thoughts. Part of the reason I wanted to do this is that while I have read 1984 many times, and many of the books on the reading list I’ve read many times, I haven’t often really concretized my thoughts about them.

I just take the journey and let the thoughts wander around in the background as I live my life. I wanted to put them on paper and maybe share them with others to see what they think my concrete takeaways are from the book, if I could try to convert them into words. So the first one for me, especially later in life as I’ve been reading this book, is that when everything else or most things that make you human are taken away by a totalitarian state, the last thing that’s left, which is the most difficult to take away, is love. Love for other human beings, love for life itself. That’s the little flame from which hope springs. The key revolutionary act is the act of love.

Lex Fridman
So when the ability to speak is taken away, when the ability to think rational thoughts is taken away, the last thing that’s left, and the thing that ultimately gives hope, is love. That’s a big takeaway for me. The note that Julia gives to Winston reading “I love you” is the kind of revolutionary act that leads to a society beyond the one they exist in. I think a lot of the book has an interesting hypocrisy to it, where the main character, Winston, is almost in an animalistic way obsessed with destroying the state in rebellion and revolution. But I think love is the thing that allows you to believe in a place beyond the state, in believing that you can build something better, versus just destroying the thing you’re in.

Lex Fridman
I think you have to be careful as a revolutionary not to obsess 100% with destruction. Because beyond destruction, there could be chaos that leads to something much worse. I think love is the basic human thing that connects all of us, the messy thing that connects all of us, that allows you to build a better society after the totalitarian one is overthrown. What else did I want to say? There’s an interesting tension there between love and lust. I think there’s a quote that pure love or pure lust was impossible or forbidden. “Pure” here meaning unadulterated, uncensored intensity of feeling, maybe intimacy.

And there was an interesting question raised by the book, both by Winston and Julia: what is ultimately the most powerful act of rebellion? Is it between us humans when everything is forbidden? Is it animalistic like sex? Just lust for another human? Or is it love? The kind of love you have for a romantic partner, but even love for family and love for friends. I don’t know. I think the book almost claims that it is sex, but I think what the book also shows is that if sex is your manifestation of rebellion, that ultimately leads to something that doesn’t last. That ultimately leads to a focus on destruction versus building beyond the horizon when the state falls. So, some quotes from Winston on this.

“The more men you’ve had sex with…” Julia admitted to having sex with quite a lot of people. He says, “The more men you’ve had sex with, the more I love you. I hate purity. I hate virtue. I want everyone to be corrupt to the bone.” This kind of rubbed me the wrong way because, again, this seems to be obsessed with the hatred towards the state versus a longing and a hope—which I think hope is really important here—a hope for a better future beyond the state. Again, another quote from the book: “Their embrace had been a battle, the climax a victory. It was a blow struck against the Party. It was a political act.” So there, again, I think sex is seen as a political act of rebellion. I think that’s not the deeply human thing here.

Lex Fridman
The deeply human thing is, again, the act of love. It’s a source of hope; it’s the catalyst for building a better future beyond the revolution. An interesting side note here—and there could be a million interesting side notes, and I’m desperately trying not to go on a million tangents, to hold myself together and stay focused—is on family. There’s all kinds of love, and I think family love is a really powerful bond that connects us, and that’s one of the things that totalitarian states really go after.

Lex Fridman
And I should mention, I’m loosely using the terms authoritarian and totalitarian here. To me, authoritarian means there’s a government with complete centralized control of political affairs. A totalitarian state is beyond that; it is complete control of not just politics but also social, economic, everything. Nazi Germany is an example of that, I think, where there’s just complete control of every single thing, from the war effort to social interactions, the rules that govern social interaction, the press, all that kind of stuff.

Lex Fridman
So I think this book is more about, at least in my definition of the term, totalitarianism. Anyway, as I was saying about family, I think the way they destroy family is, one, of course with your romantic partner by forbidding passion—passionate sex, but really just passion and longing for another human being in that romantic way. And they also really reward and encourage children at a young age; they indoctrinate them to turn their parents in for thoughtcrime, whether real or not, which of course is a silly notion because there’s no nature of truth. You can just accuse anyone of anything and they’re guilty just by existing. So that’s a way to attack the family.

Lex Fridman
And I should also have mentioned on the topic of love that I think the goal of the Party, the final destination as described by O’Brien through the process of torture, is to break your mind, heart, and soul completely so that the only love you can have—and it could be felt as a pure love—is for Big Brother. This is the kind of thing you see in North Korea, where the only love you’re allowed to have, the remaining inklings of feeling that might still exist in you, you can channel only not towards family, romantic partners, or friends, but towards this leader, this godlike messianic figure. In this case, one who may or may not exist.

Hate
Lex Fridman
In all cases, that figure, while there is a human associated with it, is really much bigger than the human, and that’s the only love you’re allowed to have. So the other takeaway I have is on the topic of hate. I think all humans have the capacity, almost an animalistic craving, for hate of the “other,” the enemy. Whether it’s individuals like Emmanuel Goldstein or nations like Eurasia and East Asia—which are the two other superstates described in this book—they’re constantly at war with each other. Again, the fascinating thing about the way this book is written is you don’t know if Eurasia or East Asia even exist. You really don’t know what is true beyond the local interactions of the main character.

Lex Fridman
And that, I think, is the point. When you don’t really know, there’s no steady footing on which to construct a worldview from which you can have hope for a better future. This animalistic craving for hate, especially when we’re in crowds, is most powerfully illustrated in the “Two Minutes of Hate” practiced by that society. The quote is, “The horrible thing about the Two Minutes of Hate was not that one was obliged to act a part, but that it was impossible to avoid joining in. Within thirty seconds any pretence was always unnecessary.

A hideous ecstasy of fear and vindictiveness, a desire to kill, to torture, to smash faces in with a sledge-hammer, seemed to flow through the whole group of people like an electric current, turning one even against one’s will into a grimacing, screaming lunatic. And yet the rage that one felt was an abstract, undirected emotion which could be switched from one object to another like the flame of a blowlamp.” That’s the point: you get the crowd together, and you get them to hate Goldstein or Eurasia or East Asia. You get them to hate anything. And that feeling, that drug, that mass hypnosis, can be directed by the state in any direction.

Lex Fridman
And because you have complete control of history, you can direct it on a day-by-day basis towards any target. As long as the hate is catalyzed through these kinds of rituals, it can overpower the individualistic feeling of love we have for each other. So that hate is a more animalistic desire. I don’t know what to make of it. And of course, it’s also important to say that this book was intended originally by Orwell as a satire, although a satire that has quite a lot of torture at the end and doesn’t seem to have much humor. But I think if you read it as a satire, that’s the best way to understand its relevance in our society today.

Because a lot of things, like the Two Minutes of Hate, are almost a caricature of what hate looks like in a mass gathering. But if you take it as a caricature, it can reveal some of the elements that already exist in human nature that we should be very cautious about. It reveals the very thing that, if not monitored by ourselves, can result in a slippery slope that leads to tribalism, the destruction of other groups, and then control of the collective intelligence of our species through a totalitarian state. I think there’s elements of this under illustration in social media today, though I don’t want to overstate it.

I think just like comparing things to Hitler, comparing things to 1984 is a reach in most cases. But social media does reveal this kind of mass hysteria, this capacity of humans to be outraged based on tribalism. So we have to understand it. We have to resist giving into it on the individual level. And I do believe we have the responsibility to create technology that helps us resist it, that incentivizes us not to be cruel to each other just because the people in whatever tribe we define ourselves in are being cruel to a particular person or group. Another takeaway I have is about power. Ingsoc, the totalitarian state, wants only one thing, and that is power. Power is both the means and the end. Absolute power.

Power
Lex Fridman
As O’Brien describes in the torture part of the book: “The real power, the power we have to fight for night and day, is not power over things, but power over men. Power is inflicting pain and humiliation. Power is in tearing human minds to pieces and putting them together again in new shapes of your own choosing. Power is not a means, it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish a dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power.” This, of course, is another aspect of human nature: the will to power and the tendency of that power to corrupt.

O’Brien says also, “The weariness of the cell is the vigour of the organism.” Through the torture and breaking of the individual, the individual doesn’t matter. What matters is the organism. There’s been a lot of brilliant comments throughout social media and on Reddit—I just want to highlight something about this because I had the exact same feeling as I was rereading it.

There’s been a lot of brilliant comments throughout social media and on Reddit—I just want to highlight something about this because I had the exact same feeling as I was rereading it. There’s a comment from a Reddit user whose name is BraveSky6764.
Lex Fridman
He said the conversation between Lex and Michael Levin, who is a brilliant biologist and engineer, came to mind when O’Brien made an analogy to an organism which survives even as the individual cells pass away, and the great purges are analogous to the cutting of a fingernail. If you see society as an organism—which I think is the way a totalitarian state sees it—then the destruction of a large percentage of that society, the murder, the torture, and all kinds of atrocities and genocide become “justifiable” as long as the organism flourishes. That’s how you get to the ideas Stalin had: it’s okay to break a few eggs to make an omelet. This devaluation of a human being as having fundamental importance in a society…

is a slippery slope into atrocities. It’s not just deeply unethical from our understanding of morals and ethics; it is also very unproductive. It destroys the human spirit, and the human spirit is essential for building a great society of constant progress. I think that’s also one of the other messages of the book, is about utopia—that totalitarianism results when you chase perfection, when you present this idea of utopia. There is no utopia; there is no perfect society. I think, at least for me, that’s the takeaway. I think the optimal state of being for an individual and for a state is constant change and constant turnover.

In the case of a state, it’s a constant turnover of leaders and ideas, always hopefully making progress towards a better world. But it’s always going to be messy. Perfection only exists in an oppressive state. Perfection only exists when you remove the basic humanity of the individuals that make up that state, when you destroy the human spirit or suppress all freedoms. Freedom is going to be messy and chaotic, but that freedom, ultimately, in the long arc of history, is going to create progress.

So yes, as the Redditor BraveSky6764 says, that does give you a perspective of a biological system made of living organisms. Each one of us is made up of living organisms, and we take for granted all the “atrocities” happening there; we don’t seem to give a damn. I think that’s a good metaphor. If you want to put yourself in the mind of the Inner Party, of Big Brother, or the people in power, I think most, if not all of them, see themselves as doing good for society. They are able to justify things the way we justify the death of different cells in our body.

You don’t even think of them as worthy of consideration. You don’t think of them as living beings having the same value as you. That’s one of the really powerful ideas at the founding of the United States: that all men are created equal, that there’s an equal worth to a human being no matter who they are. That idea, as flawed as its implementations have been, is a really powerful and non-trivial idea, and it resists the drug of totalitarianism and power. I do believe that on the topic of power and politics, 1984 has been misused by political ideologues.

I’ve seen it, for example, when conservatives in the United States have used 1984 to call left-wing policies “Orwellian.” I think that’s an overstatement, of course used for dramatic effect, but it should at least be said that Orwell was a democratic socialist. 1984 is not a criticism of socialism; it’s a criticism of totalitarianism. I think the point is a warning that all political ideologies can succumb to the allure of power and be corrupted by it. People on both the left and the right in the United States can be corrupted by power. This one-way criticism of policies as Orwellian is a convenient shorthand, but the reality is all politicians are capable of…

creating an Orwellian world. And I think one of the things that is highlighted in the book very well is the hypocrisy of Winston. When O’Brien asks Winston what he’s willing to do to overthrow the Party, Winston admits he is willing to commit atrocities. He’s willing to do evil unto children, to commit murder, anything. This is a powerful illustration that both the totalitarian state and a blind, immoral rebellion against it can be evil. This is where I return to love as the thing that carries hope for a world beyond this battle for freedom. You have to have that.

Otherwise, the Orwellian state and the resistance to an Orwellian state can both destroy basic human rights and freedoms. I think in the character of Winston, that’s illustrated well. And I should also mention that there’s interesting writing… Now, I’m not obviously a scholar of Orwell, and there’s a lot of books been written and I should probably recommend them somewhere. There’s just great books written on 1984, on Orwell, on the historical context in which he was operating and all that kind of stuff. But as far as I see, Orwell also with 1984 and himself politically, he was not espousing the complete opposite of totalitarianism.

There is, again, democratic socialism—that there is value to the connection between human beings, that you have to lean on each other, help each other, that society is fundamentally more a cohesive collective than a completely disparate set of sovereign individuals. It’s both. And I think he was torn about that idea, because in order to resist a totalitarian state you have to fight for those basic individual freedoms. But at the same time, a well-functioning society allows for that freedom to manifest as collaboration. And so that’s the difficult challenge there.

Again, that’s why he was a democratic socialist and the criticism of the book was against totalitarianism, of a centralized state that controls speech, thought, the press, and all the basic human freedoms. Controls truth. And I think a lot of people would ask the question, and I hear this tossed around: “Do we live in the world of 1984 today?” And I think that’s used as a shorthand to sort of criticize different policies and different governments. I generally don’t like the use of that kind of language because it’s basically crying wolf. If everything is 1984, if everybody is Hitler, then you’re not going to…

There’s no way to properly normalize the discussion of the lesser of two evils, which is ultimately what democracy is about. You have a collection of things you’re picking. They all kind of suck, but you want to pick the one that sucks the least. That’s human society, you know? That’s human nature. It’s messy. And so I don’t think we live in a 1984 state, but there’s a lot of elements that this book reveals about human nature and about the operation of a totalitarian state that we should be on the watch for. So surveillance, a state of doublethink, of controlling language, of being in a constant state of war as a way to control the population and the flow of resources.

All those things have elements of almost useful tools for the establishment of complete control of a populace. And the moment you notice those elements, it’s our job to resist those elements. So I think the point is we have to be vigilant to the slippery slope of the will to power in centralized institutions. Another thing I want to mention is that I think a lot of people rightfully compliment Orwell for predicting some of the elements of future society, especially with technological capabilities, for example, telescreens used by the state to control the population. Maybe I can make a few comments on technology in general.

Technology
Lex Fridman
People who criticize technology will often use 1984 as an example that technology is a tool for a totalitarian state. It’s a way they can achieve full control, and we should be extremely cautious of it. And I think there’s a kernel of truth to that. But it’s not obvious to me that on the whole, technology is a tool for totalitarian control. I think it is also a tool for freedom. The internet is an incredible tool for freedom. And so of course, we have to fight for that freedom, but I believe in general, the greater… Let’s just take the internet broadly as an example, and there’s a lot of sub-elements of that, and like a more platonic sense of what the internet is, which is digital interconnectivity.

We have to fight for freedom, but in general, the greater reach and access that the internet has, the more powerful the resistance to totalitarianism. Technology is a double-edged sword. It provides the tools for oppression and the tools for the ongoing fight for freedom. And as long as the will to fight arises in the human heart, technology, I think, helps humanity win. And of course, there’s been a lot of discussion about free speech and the freedom of thought, and there’s a lot to be said there that’s much more nuanced than the book 1984 provides. I think 1984 just shows the end, horrible conclusion of complete totalitarian control over speech, over thought, over feeling, over everything. But in general, my view of it is it’s a kind of inspiration to…

In order to prevent ourselves from slipping into an authoritarian or a totalitarian state, Orwellian type of dystopias—to avoid them, we have to value critical and independent thought. I think thought first, before speech. Just thought. I think you have to learn to think deeply from first principles, independent of whatever tribe you find yourselves in. Independent of government, independent of groups, independent of the people around you, the people you love, that love you. You have to learn, at least sometimes, to think independently. Now, this is the Nietzsche, “If you gaze long into the abyss, the abyss gazes into you.” If you think too independently, it can break your mind. I mean, we are social creatures. We need that connection.

But I think it’s like with Tom Waits: “I like my town with a little drop of poison.” I think of truly, deeply independent thought as a little drop of poison that’s necessary for your mind. Most of your life you live, you kind of assume most things around you are true, and that’s very useful. We stand on the shoulders of giants. But you, on a regular occasion, have to question. Question your assumptions, question your biases, question everything. Question the things you’ve taken for granted. Question what everybody’s telling you. But not too much. It’s a tricky balance, but the act of rebellion against a totalitarian state, against the slippery slope into that state, is that independent thought. And of course, speech is a manifestation of that thought.

So we have to avoid echo chambers in both thought and speech. Like I said, you have to question your assumptions, challenge your biases. I think that’s the way out. Or maybe that’s a resistance mechanism to slipping into authoritarianism. And maybe I have a few more things to say about the latter part of the book, the part where there’s torture—where there’s Room 101 that has the thing you fear the most, which is different for all of us, and for Winston, that’s rats. It makes you wonder what that thing is for each of us. I left a mental note for myself to do more research into the historical context, the psychology, the neuroscience, the effectiveness of torture. I think there’s probably a lot of really good work.

I had a brief conversation with Andrew Huberman on the phone about this topic. Andrew Huberman, the brilliant Andrew Huberman, host of the Huberman Lab podcast that you should listen to. And he mentioned to me that there’s a bunch of papers on these topics. This has been studied, sort of the carrot and the stick of the ability of incentives and disincentives to control the perception and the mental state of people and animals. And he mentioned to me a few folks that I could talk to on a podcast about this topic, and a few books. So, I’ll definitely look into this more. I think 1984 uses torture as a philosophical description, as a caricature of the operation of a totalitarian state.

But at the same time, a lot of those elements were all done under Stalin in the Soviet Union, so it’s not like it’s very different or very far from reality. It’s very, very real. The question is about the actual effect it has on the human mind, which I really have to think because torture in this case breaks Winston. In fact, I’d like to believe that many people, in the most fundamental of ways, can’t be broken in this way. I’ve seen science… again, without extensively reading, so please correct me if I’m wrong. But I’ve seen science that shows that torture, for the purpose of intelligence gathering, is not effective.

It’s not effective to get accurate information because people will tell you anything, really, to stop the torture, stop the physical and the mental and the emotional suffering. But I think this book is about the use of torture to completely break your ability to think and to perceive the world. One of the things I talked to Andrew about is whether it’s possible to control perception through these kinds of things. And it seems that there is literature that shows it’s possible to literally change your perception of the world. Like in this case, in 1984, it’s when you’re holding up four fingers, can you actually make the person believe that you’re holding up five fingers?

Not because of some weird delusion or just because your vision is blurry, but you literally, when you look, are holding four fingers and what you see is five fingers. Not because your vision is poor. No, your visual cortex, the way you’re processing that information, something about the processing changes completely your perception. If I tell you there’s a straight line, can, through incentive or disincentive, you start seeing a crooked line or something like that? Anyway, I think that there’s literature that supports that, which is, by the way, terrifying. But the thing I’d like to research more is if that can be long-lasting. I just don’t believe it can be.

If you’re not pushed to your death, yes, maybe perception, maybe your willingness to think, but your actual ability to think independent thoughts? Maybe you’re terrified. I understand if you’re terrified of any more thinking that leads to rebellious thoughts. Like the book mentions, the idea of face crime, where you can reveal your thoughts, the inner workings of your mind, by the subtleties of your expressions in your face. And I think also, like O’Brien says, “If you want to keep a secret, you must also hide it from yourself.” So I can understand that.

And maybe that is the basic mechanism that torture leads to: that your body, your mind learns to hide the truth from yourself. Like you don’t even allow yourself to think it because you know if you think it, it’s going to lead to face crime and thought crime, and that’s going to lead to more torture. That’s possible. But I just can’t imagine the capacity for love in the human heart to be extinguished through torture, finally extinguished. Temporarily, yes, but finally, irrecoverably, which I think is the basic claim of the book. That they break… so because through the worst of the torture Winston gives up Julia, the object of his love, he says that some things like that—the fact that you said, “Torture her, not me.”

“Anything to make this stop,” the fact that you said that, the fact that you thought that, is a statement, is a thought you can’t walk back to yourself. So it’s irrecoverable. You just destroyed your faith in love? I don’t think so. I think it’s possible we have to remember that this is one particular character. This is one particular story. I think there’s a lot of people in which the capacity to love cannot be broken, no matter the torture. But that’s an interesting scientific question, but it’s also a human question. I think Man’s Search for Meaning—there’s a lot of books that explore those kinds of questions. In the worst of conditions that humans had to suffer through, what still persists? What is the source of meaning?

And I just think that the flame of love persists through atrocities, through torture, through suffering, through all of it. But the claim of the book is that yes, a totalitarian state can use torture to break even that, even that which leads to the only love you’re allowed to have, which is the love for Big Brother. So I think, practically speaking, from the Party’s perspective, I think the point of O’Brien’s torture of Winston was to suffocate the hope in his mind and heart, so there is no hope, by completely destroying the knowledge of what is and isn’t true, so being betrayed.

And this kind of Goldstein’s book about the society, not knowing if that’s true, not knowing anything about Julia, is basically having no emotional or intellectual ground to stand on. It’s very difficult to have a sense of where you are. To have hope, you have to have a sense of where you are and where things could be. And then you also betray yourself. To force you to be a hypocrite on your own deepest feelings of love, I think basically puts you in a place where there’s no hope, there’s no point. It’s apathy. It’s nihilism. And there, a hardworking member of society that is nihilistic is probably what the Party wants, because that human will not rebel.

And there, a hardworking member of society that is nihilistic is probably what the Party wants, because that human will not rebel.

But on the point of hope, I should mention that there’s a kind of long-running theory that since the appendix… The appendix is about the details of Newspeak, the language that the Party is creating and enforcing. Because that appendix was written in the past tense, and it’s talking about Newspeak in the past tense and it’s written in English, sort of non-Newspeak, that means the Party and Newspeak and all of its elements that we see in the story are in the past. That the world from which the book is created has escaped that. And that’s a message of hope. That whatever the rebellion against the Party—whether it’s passionate lust and sex, whether it’s love, whether it’s seeking truth in a world full of lies—whatever it is, there’s a way out.

Again, to me, the way out is love. But that’s a hopeful message in this dystopian novel, that even these perfectly executed totalitarian states will fall. I took a few random notes here that maybe I’ll comment on. I wrote a quote: “The masses cannot rebel until they become conscious.” That might be either a Winston observation or an O’Brien statement. I’m not sure. But yeah, so you have to think, 80% plus are proles of the working class. They have the power if they want it, but they don’t want it. They don’t want to take it. That’s the whole point of the totalitarian state: to break your will for freedom, your desire for freedom, break your ability to know that you’re not free.

And that’s where all of it—the changing of history, the doublethink, the thought crime—all of that comes into play: the torture and the Ministry of Love. All of that is about preventing the populace from becoming conscious. And again, as per the cells discussion earlier, I wrote down the O’Brien quote: “The death of the individual is not death. The Party is immortal.” And this is just an interesting observation about the operation of a totalitarian state, that it’s the idea and a kind of amorphous symbol of the messianic figure in Big Brother is all you need for the Party to persist. That person doesn’t actually have to exist. Any one individual doesn’t have to exist.

It’s just the division of society into high, middle, and low, and the oppression of the low by the high by the centralized Inner Party. That’s all you need, and the individual does not matter in that. And again, the way to fight that is to fight for individual freedoms. An interesting side note is just a quote I wrote down from Julia, I think: “If you keep the small rules, you can break the big ones.” And so she, in the book, is somebody that follows to the T all the rules of the Party. She attends all the committee meetings and all that kind of stuff, and just is like the model citizen from the perspective of the Party. And so that allows her to break the big rules, like having passionate sex with people—the really…

or falling in love, all the forbidden things. And I think that’s actually a good way to exist in the world. I think for a lot of us, there’s probably a bunch of things that bother us in the local world around us, in the bigger world, and I think you have to pick your battles. You have to not get lost in the muck of small battles if you want to have at least one or a few big victories in your life that make for a better world. I think, at least in my sense, it’s easy to get distracted by the little things that bother you in life.

And I think staying focused on the big things, again, picking your battles, and staying with that for as long as possible, working your ass off to solve one problem for as long as possible, not giving up against impossible odds, against all the criticism—that’s the way to solve those big problems. And of course, that’s not what Julia is talking about. But in a sense, she is also, because in that particular case, a totalitarian state is the problem. And the way to rebel is to plant that seed of rebellion in each of the people she has sex with: that we are human, that we have lust for each other, that we have the ability to love each other, and that is the necessary act of rebellion there.

That is the big leap for her, at least in that kind of society. I should also mention that there’s a lot of interpretations of the different small and big things in this book. So it’s very possible in the case of Julia that Winston was played. He was set up with Julia. He was set up to feel all those things. He was set up to have that little secret cove where he can write on his desk in the diary and dream of rebelling against the state, dreaming of the Brotherhood. It’s unclear to me why an oppressive state would want people to have that little journey of desiring freedom in all its manifestations. I’m not sure.

But maybe O’Brien’s statement that the purpose of torture is torture holds some wisdom: that to attain absolute power, you also have to have a willingness and a mechanism to attain absolute suffering in the populace. And maybe this is a way to maximize suffering: to give them hope before you crush it. Again, the way out to me and the takeaway from this book—the way out is love. Perhaps this is a good place to also mention a little bit of a fun little controversy that evolved over Twitter. So I posted a reading list quickly before heading off to a New Year’s party of books that I hope to read in 2023, and these are based on books that I asked people to vote on; these are many of the ones they selected.

Reading list controversy

And they happened to be many of the books I’ve read many times throughout my life and really enjoyed, and they were like old friends that I love visiting and revisiting. Every time I read them, I get something new and they just read differently throughout life. You know, the way in my teens when I read The Stranger by Camus is very different than it was in my 20s and different in my 30s. I’ll say my favorite book now by Camus is probably The Plague, and all of that has evolved. With Dostoevsky, I read The Idiot several times. I read The Brothers Karamazov both in English and Russian, and Notes from Underground. I mean, I love Dostoevsky. And a lot of these books are just…

Yes, they are classics, but they’re also deeply profound and they move me on an intellectual level, but also just as a human being. They’re like travel companions. They’re like old friends. Old dead friends. So yeah, I wanted to celebrate my love for books. And it was very strange to me that—and if I’m just being honest for a second, it was kind of painful that some prominent figures that I respect were kind of cruel about the list. They responded and they mocked it and all that kind of stuff, basically taking the worst possible interpretation. I have to be honest and say it wasn’t fun, because it was just a silly kid—me—kind of in a joyful New Year’s mood, sharing with the world books I love.

And I think what was happening—and this seems to be happening a bit more—is there’s a bunch of people that are just almost waiting or hoping that I fail, or maybe that I’m some kind of bad human being. They’re looking, they’re trying to discover things about me that reveal that I’m a bad human being, and maybe somehow this reading list reveals that. I don’t know. So, one criticism was that everybody read these books in school, and they’re basic. I think my response to that criticism is: no. First of all, most people have not read them in school; maybe they read CliffNotes. And they’re not basic; they’re deeply profound, some of the greatest words ever written.

But also, I don’t think I’ve ever gotten a lot from books I was forced to read in school when I had to read them for an assignment. Some of these books I think I read in school, but most of them not. It’s only when I read them outside of school on my own volition that I really gained a lot from it, and especially throughout my life at regular times—as a teenager, in my 20s, and in my 30s. So, no. These books are profound and deserve returning to. Like I said, they are old friends that give me a lot of meaning every time I revisit the ideas, and they give me a new perspective on life. Another criticism was very nitpicky. The list was put together really quickly, and the goal—I like setting tough goals.

The goal was to read a book a week. And, you know, on one week I had The Little Prince followed by The Brothers Karamazov. And people criticized that: “How can you possibly read The Brothers Karamazov in one week?” Maybe I won’t. Maybe I’ll fail miserably. But I love trying. But that wasn’t actually the goal. I should’ve said I intend to finish reading it by the end of that week. So, you start earlier because The Little Prince takes an hour or two to read. And then for The Brothers Karamazov, I could have the two weeks. It should take about 30, 40, or 50 hours to read it. That said, friends, I’ve read it already in English and in Russian.

I’m interviewing the world-famous, amazing translators of The Brothers Karamazov, of Dostoevsky, and of Tolstoy—Richard Pevear and Larissa Volokhonsky—probably across multiple days. So, this book means a lot to me. I’m not somebody just kind of rolling in, “What are the cool kids reading these days?” These books have been lifelong companions to me. And the fact that people just want to stomp on that—and a large number of people did, people I respect—yeah, I’d be lying if I said it didn’t suck a bit. Anyway, the love for reading persists. I have to say, after that, I was very hesitant to even make this particular video on Orwell, on 1984. And I’m not sure I want to be public with my reading after this.

And I know a lot of people will say, “No, we’re here with you.” They’re very supportive, and I love you. I mean, I meet so many incredible people, but the reality is it just does suck to be vulnerable and share something with the world and receive that kind of mockery at scale. So I will definitely—I will not be affected or broken by any of that kind of stuff for something that’s actually meaningful, like the conversations—some of the very difficult conversations I’m going to do. But for a silly side hobby thing of reading that I do throughout my life to be a source of mockery, I’m just going to do that privately. So, I’m a little torn on that, and I’ll try to figure out a way.

Also, I should say that that list, like a lot of things, is kind of aspirational because if I take a job at a tech company, or if I start a tech company, or if I have to travel for extremely difficult conversations and really have to prepare for them—all that kind of stuff is going to affect my ability to both read and enjoy reading, which I think is a prerequisite for this kind of reading. But in general, what I do is I read about one hour a day on Kindle—on the sort of physical device, in my eyes. And depending on the workout I do and the chores I have, it’s going to be about two hours of audiobooks. So, most of the things I do during chores is audiobooks.

And when I run—and I usually run about 10 to 15 miles, so you’re talking about—I often run over two hours. It’s like a slow pace. When the days are not insane, it gives me a chance to think and a chance to listen to audiobooks, so I love that process. It’s an escape from the world, a chance for me to collect my thoughts. And yeah, it’s again a source of happiness and joy, and I wanted to share that. I think you can get quite a lot of reading done through that process, especially if it’s a book you’ve read before. It is very challenging to do this kind of takeaway video, or to concretize your thoughts down on paper, especially when you have to present them in this kind of way.

I’m not sure I’m going to do that much, because it’s an extra bit of effort. But it’s also a chance to share that joy with the world, and to find cool people that also enjoy it. So it’s a trade-off. Anyway, it’s just a temporary thing, but it did suck for a short amount of time—for a few hours, for a couple of days. But in general, I’ll persist with my love of reading. I might not talk about it publicly as much. But again, let me emphasize that this kind of response and mockery will not affect anything of importance that I do. I try to read comments; I try to see criticism. I really value especially high-effort criticism. I try to grow and constantly try to improve.

But that’s for things that I take very seriously, like the podcast conversations that I do. But for silly things, like book lists, Spotify music playlists, the food I like to eat—I don’t know, anything, any fun side thing—it’s not that important. If it’s something that others don’t enjoy, then whatever. I’ll enjoy them probably with my friends locally here, or the people I meet. So, anyway, I love reading. I love reading classics. I love returning to old friends in book form, and making new ones.

There’s a bunch of science fiction that I embarrassingly have not read and would love to, because those worlds are so meaningful to so many of the people I’m friends with that I can’t wait to visit those worlds and sort of make new friends in the form of books. So, definitely the love for books, the love for reading persists. And if you share in that love, that’s beautiful. So thank you for joining me on this journey. Thank you for watching this silly little video. And I hope to see you next time. Love you all.
