Welcome to Manifold. Today's episode is an interview that I recorded with the podcast Deus Ex Machina. The host of that podcast, Bohan Liu, grew up in China, attended Yale University, where he studied computer science and religion. And in our conversation, we get into topics ranging from geopolitics, U.S.-China competition,
genomics, and we even get into questions like free will and my views on religion. It's a unique conversation, and I think you'll enjoy it. Thanks for coming to the show. ♪
Super excited to have Professor Stephen Xu on today. Professor Steve is a professor of theoretical physics and I believe computational mathematical science and engineering at Michigan State University. And Steve is also a co-founder of multiple companies, including Genomic Predictions, which uses pre-implantation genetic screening devices for human embryos, and SuperFocus AI, which makes narrowly focused, non-hallucinatory AI that's actually useful for enterprises. But yeah, I think that's the
Steve Fischelbao. I'm happy to touch on multiple subjects, I hope. But as I was going through Steve's extensive blog, and I think you've been blogging for over 20 years now, maybe one of the earlier ones on the internet, I basically went through, I think, most of your blogs to do some research. And it is just all kinds of topics, you know, from China to genius to, you know, obviously your field of genetics. So it's quite fascinating. So I'm very excited for the conversation today. Thank you so much for coming on, Steve. I'm happy to be here.
Awesome. So starting off, I wanted to talk about something that kind of struck me, maybe visually looking at your background and you, is that, you know, you're an Asian American who, you know, got a PhD in physics and is now a professor. Okay, that all tracks. But then you actually, you're a pretty big guy. You played football, college football at Caltech, went back when they had a football team. It was a D3 team, but still college football. And then you also, you know, did things like jujitsu and martial arts. And, you know, actually, the only other
football playing mathematician I know is John Urschel, who I believe is in my team, which I'm sure you've heard. He's a little better player than I am. You did talk about at some point maybe realizing that the NFL maybe wasn't for you, you know, you showed some promise. But I was kind of curious about how you decided to get into sports and, you know, growing up as an Asian American, especially at a time when, you know, maybe the stereotype was even stronger when growing up about associating Asians with math and just STEM and not sports and athleticism.
Yeah, interesting question. I mean, there's several strands to this discussion. Part of it comes from my family background. It turns out my mother's side of the family is a military family. And so my grandfather, my mother's father, attended the same military academy as Chiang Kai-shek and was a general in the KMT.
And when they moved to Taiwan, he was actually briefly in charge of the Navy in Taiwan. So I guess at one point he was kind of an admiral. So anyway, that's a very military family. And that side of the family is very athletic. So my mother's little sister represented Taiwan in the Asian Games in swimming and
Two of my cousins actually are among the only Asian Americans to actually play D1 college basketball. One of my cousins, Richard Chang, is about 6'7", and he was a power forward at Cal. And he was recruited pretty widely. He could have gone to UCLA or other schools as well. So pretty athletic family on that side. And then I guess I learned from my father's side
The Xu side, which, you know, recently comes from Zhejiang mostly, they actually, this is a weird thing, like everybody knows about the imperial examination system, but there was some kind of combined hybrid system for some period of time where to be selected as a candidate in that category, they combined candidates.
physical activities as well as like your ability to do well on the written tests. And so there were even things like weightlifting and I don't know, horseback riding, just all kinds of crazy stuff. So for some reason, like we have this weird multi-thousand year family history that I think I blogged about it at one point. You can look it up, but
My relatives in Zhejiang gave it to us, and it has the names of all these, the male shoes going back thousands years, actually. And some of the more recent guys from Zhejiang actually were selected candidates based on this weird hybrid.
So I guess they were probably pretty athletically talented on that side of the family too back then. So anyway, it's a weird story. So that's one thread. So I think my mom, basically, my brother and I, she encouraged us to do sports when we were pretty young. I think basically because in her family, the military family, that was a standard thing. And so my brother and I were competitive swimmers for a long time.
And so, I don't know, I just gravitated toward that kind of stuff. I actually like contact. I like hitting people in football and I like wrestling and jujitsu and judo. I just like that kind of stuff. Not everybody does. I had friends who were basketball players or track people or even other swimmers who, if you just grabbed them, they really didn't like it. And...
Yeah. Let alone getting hit in the face. So, yeah, I think it's kind of just hardwired. Right. And yeah, go ahead. First of all, you know, extremely illustrious family history. So my great grandfather was also in Guangmingdao, but he was just a mere, I think, deputy secretary to a county. No, not a general. That's also why our family history probably only goes back 150 years, I think, to the late Qing dynasty, whereas you go back thousands because, you know, your family is more worthy of record keeping. Yeah.
But, you know, I think you mentioned that, yeah, at some point, the Chinese maybe in pure exams added a physical component. And then they probably got away, got rid of that at some point. Because growing up in China, I don't think it was that big of a deal. There's some element of it. I remember I was forced to learn how to swim in Shanghai because it was a second grade. The government at some point decided that there could be major flooding.
And we need to make sure the populace knows how to swim for safety. So everyone had to learn how to swim. And I did that. But I think actually recently they've started bringing some of it back in an effort to kind of rejuvenate the nation and re, you know, masculinize nation. And so now, now it's actually a heavier portion of the, I think both middle to high school and high school to college exam, which of course each Asian society means there's, there's a whole industry of test prep geared towards physical test prep now to just optimize it, to get those scores, you know, as, as our society does. Yeah.
But I just, I think like, you are an interesting embodiment, I think, of these ancient virtues that China has valued historically, which is the combination of the intellectual and the martial. Which I think has kind of fell to the wayside a bit more recently. And I know the ancient Greeks were also people that cared about that too. I feel like, you know, in our society, we kind of see a bit more of this dichotomy, right? Imagine the scrawny nerd, and they're not supposed to be jocks. If the jocks are separated, they're supposed to be dumb, you know?
Yeah, why do you think we, you know, kind of like maybe lost some of that emphasis on this well-rounded, both physical, men's and modest kind of integration of a full man? And, you know, whether you think there is any, maybe due to increased specialization, whether the world inherently has to split a bit more to focus on their model? Yeah, it's a super interesting question. And also to get back to what you asked me earlier about the stereotype of Asians being
not athletic. For the historians out there, I'll point you to an interesting fact. If you go back to the LA Olympics, which must have been in late 20s or early 30s or something. There was an LA Olympics also in, I think, 84 or something, but the previous one, which was early in the 20th century. If you go and you do a little research, you'll find that the Japanese swimming team
was the dominant, by far the most dominant swim team in the world at that time. And they had a tradition where, I guess because of the samurai were required to learn how to swim. They were required to be strong swimmers. And so they just had a tradition of it and also physical culture and stuff like that and judo and stuff like this. And so people just don't realize like these things are time and culture dependent and
And, you know, I think the modern kind of HPD people who want to think of Asians as non-athletic would be shocked at what people wrote in the newspaper about the Japanese dominating swimming back then. And so anyway, things are more complicated than I think you're the simple minded modern approach. The way things are today isn't necessarily the way they quote have to be. Now, in terms of like, I think there definitely is an idea in Chinese culture that
it does not particularly value the physical. So that's, I think a Confucian idea that not only, you know, is, is, is the Confucian scholar, the ideal person supposed to be very cerebral and have very high self-control and be a role model for other people doing mundane things like working in, you know, with soil, like, you know, with that, you know, like, you know, the Chinese word, no mean. So the, the,
All that is like kind of denigrated, even being a merchant or a soldier is denigrated. And so I think that has a long term effect for what families tend to pour their energy into. And one thing I'll point out is that growing up in Iowa, which is really one of the most kind of all American places you can grow up.
All of my friends' dads, or at least predominantly, some of them were nerdly professors, but a lot of dads would take their kid out, their son out, and throw the football with them or throw the baseball with them or play basketball with them. That was much less common among the Asian American kids. Of course, that sets you up. If you're trying to make the seventh grade basketball team, of course, if you spent a
With your dad showing you how to do it, you're going to have a huge advantage, whereas a lot of Asian kids generally wouldn't have had that extra time. So it's all much more complicated, I think, than people think. Yeah, and did your dad ever...
Throw the ball with you, you know? No, that's the funny part of it. My dad was actually literally a kind of Confucian scholar. So he didn't really do that with the kids. But luckily for us, my mom came from a very like athletic, active family. And so we were competitive swimmers from I was a competitive swimmer since the age of like seven.
And, you know, I did other sports as well and took judo when I was growing up. Yeah. And so just to mention your grandfather, I believe, was a general. And you said went to the same military academy as Chiang Kai-shek. Is that the one in Japan where he was trained or are you talking about Wanpola Academy? Exactly. No, in Japan. So he both he and Chiang Kai-shek studied military, were trained in military education in Japan, I think in Tokyo, actually. Right, right. And I'm wondering, you know, growing up with that kind of family background,
Did you guys talk a lot about Chinese politics growing up, and did that influence your family's views on the politics in mainland China and cross-race relations? You know, we actually, again, this is a funny inversion, that although my dad was an officer also in the KMT military, he went to college in
During the war, he went to he was in college in Kunming, this special university that was made out of four different, you know. Yeah, exactly. So he spent the war there. And then afterwards, he was actually an instructor briefly at the Air Force Academy training pilots because his field was aerodynamics. So anyway, he was also he also had a military background.
The funny thing, or at least in that era, the World War II era, a lot of men had military backgrounds. But the funny part of it is, though, although my mom's family was involved, obviously, at a high level with the KMT, I didn't ever hear anything political ever from my mom. My mom just wasn't that kind of person. But my dad's family was getting basically screwed over in the Cultural Revolution because they were still in Zhejiang when I was a kid. So this would have been like late 60s, early 70s.
And I heard my dad would get these letters from his relatives in China and they were written on the thinnest, cheapest, shittiest paper. That's all probably you could get in communist China, you know, at that time. And they would write like very densely on these little letters. But those letters were like priceless to my dad because they were his only contact with his family back home. And he would.
spend time telling me about how terrible the cultural revolution was and what his family was going through and how it made people into animals. Like the brothers did terrible things to each other and to the father, to the parents, taking stuff from their house and just really terrible stuff. And it's very funny because if you're an intellectual kid and you grew up in that era, a lot of intellectuals were pro-
pro-communism, pro-leftism. And there was a kind of like romanticization of, you know, both the Soviet Union and communist China by leftists here in the United States. And so I would come home like I like some of my friends, parents who were leftists, like this is a university town. Remember, I would be at their dinner at dinner at their house and hearing all this conversation.
stuff about how bad capitalism is in America. He might come home and talk to my dad and my dad would be like, those people don't know fuck all about what they're talking about. Your relatives are being fucked over. My dad would never use language like that. But your own relatives are suffering in China right now and these people know nothing about it. And so in the modern era, I am very, very able to discount
quote, expert opinion, because, you know, these professors, they quote, experts can be 100% wrong in, you know, very strongly held beliefs. And it's only in a few technical fields where the way I like to say it is that if you say something that's wrong, the facts or the mathematics are going to punch you in the face right away. And it's only in those sub-disciplines where if someone's, quote, an expert, that means something.
In all of these other fields, sorry, people train all my friends with PhDs in history and, you know, other subjects. Like literally you'll find people who are supposed to be the world's expert on a particular topic. And they're literally 180 degrees off.
Yeah, you know, the period talked about, yeah, in the 60s, 70s, when all these leftist intellectuals were enamored with these, you know, platonic ideals of communism and historical materialism, how irrationally it just seemed to make so much sense that they had to support civil union. And even on the right, the fascists had a lot of those intellectuals too. And one of the guests I'm going to have on, Professor Mark Lilla at Columbia, he's writing, or he did write a book about
I think it's called reckless mind. Basically, this phenomenon of intellectuals who really support tyranny often because they have this delusional view that their tyrant is going to implement their views and it's going to work out and things like that. You know, I just another comment on this topic. On Twitter, I'm often pointing out like,
I can't help but notice how dumb like our intelligentsia is. Well, pretty much everywhere in the world. I mean, I'm arrogant enough to say like, well, if you're not like theoretical physicists or something, there's a good chance that you're sure you're right, but you're actually wrong. And even physicists could be wrong about things too. Right. But,
One of the big things is people in the West are just totally wrong. They're totally miscalibrated about China in many respects. I'm often pointing out like simple, obvious things that are, you know, you can go and check them very quickly that they're true, but they go 180 degrees against what people say about China.
And so now I have people saying like, oh, Steve, you're a CPC shill. You're a tankie. You're a woomow. Yeah. Yeah. I'm, I'm, look, remember my dad taught me, you know, when, before any of you guys were born, my dad was teaching me about how shitty the communists were and what Mao did to our family. You know, remember that. Okay. So if,
if I tell you like, well, they do actually seem to have pretty good infrastructure and yeah, they actually did put a satellite up that can do X, Y, Z. You know, it's not because I'm pro-communist. It's because like I actually want to understand the world as it is, not how your ideology wants it to be.
Yeah, no, I actually feel very similar. So I'm a Chinese person living in the West, especially I came to the US for college in 2016. And basically two months after I came down, Trump was elected, right. And then China was just brought to the national forefront as this big demon, this geopolitical peer competitor, and you know, this bipartisan threat. And I often come off as you know, a China apologist, even though, you know, you know, there's definitely parts of the government policy I don't necessarily agree with. But just because there's things that are just
patently untrue that are said. And so I just correct the fact and then I come off as, they think, a classic butthurt Chinese person. But it was interesting when you talked about these leftists, you know, when they were glorifying communist China during the Cultural Revolution,
And how you said, you generally discount expert predictions unless, you know, it's like a really objective, you know, factually based truth. In this case, it seemed like there was an objective fact, right? Like if they actually just ever showed up there, they would see, they would see the truth on the ground. Obviously, maybe if they were on an official tour, they'd be taken to a Patankin village. But like, the fact is, they never went there on the ground. And I think that was different. Yeah. Yeah.
In those days, you could make excuses for the lack of information that a Harvard professor would have about what was going on in China because they might not be able to go there. Or if they went there, as you said, they might be tightly controlled what they could see.
So you can apologize for their lack of knowledge. You cannot apologize for the level of conviction conditional on their level of knowledge. As always, all these people in the humanities and people online who either are far left or far right or whatever...
If they're just using what I call the calculus of words, word calculus, no data, no equations, no analysis, you'll find people that are way just incredibly overconfident based really mainly on their feels. That's all word calculus is. And that's all these people have. And so they're just constantly miscalibrated. So, so.
Now you don't have such a good excuse. You can actually, people hate me on Twitter for saying shit like this and I'm always doing this. I'm like, look at this two minute YouTube video. Do you think that was faked or do you think these electric cars are actually good? Like just a few years ago, I was putting up videos of like,
guy in London or guy in Sydney, Australia or guy in Israel who bought a Chinese car because they could buy Chinese cars already at that time. And they're evaluating these cars like, this thing is awesome. It's as good as my Tesla and it costs half as much. So I'm just asking you, do you think all these people are fake? Because people would come at me and say, oh, Chinese technology, it's junk. These Chinese EVs are going to fall apart. It's all low quality. Only Tesla can make this shit. And
And so I would get into discussions like that. We'll at least do a little bit of work. And I understand if you think all these white guys who know cars and are telling you these cars are pretty good and dudes in Tel Aviv, sure, maybe it's all fake. Maybe the Communist Party is paying off these dudes in Tel Aviv. But maybe actually I'm giving you a little glimpse of the real world and you could get it yourself if you just had an open mind.
Yeah, the very first internship I ever did was working at NIO in Shanghai. That was pre-IPO, right? You know, that's China's premium electric car manufacturer. And that was working on Tongs driving the time, which didn't really pan out for them, nor did it for any of the automakers. But even that time, you could see like, it was real. Like I drove them. They were extremely good. And obviously, in the US, you don't see them for geopolitical reasons. But recently, I was in Europe and in Netherlands.
All of the Chinese EVs are all over the streets, and the people there love them. Unless, of course, the tariffs kick in and really force it out of the market. Yeah, but even now you can find guys online who will trash talk these cars. And I'm like, what is your basis for this? By now you have crazy things like GM pays some famous auto consultancy to tear down
one of these cars and do like a full report on the quality and you can go and look at it. And also like the, the consortium of Japanese automakers have done this too. And by, by now it's like totally beyond question that these are actually good cars and stuff. And yet you can still find people who will tell you like, Oh, it's all shit. It's all fake. It's, you know, so.
So I'm just thinking from the point of strategic competition between US and China, I think in the Art of War, it talks about how you want the enemy to underestimate you, right? In the sense like, you know, the Americans, maybe H.R. McMaster was called strategic narcissism, where they just refuse to see the truth. You know, it's good for China, right? Plays into China's hands, right? And obviously, I know you're an American, so you would want Americans to, you know, overcome these biases and see the competitor for what they are. But I'm kind of thinking about how
I guess from a Chinese perspective, I think during the era of Deng Xiaoping, it was very much like, bide your time, hide your strength. You want the other side to underestimate you. But in the last few years, I think China's been coming out a bit more guns blazing. In a sense, maybe even overplaying the cards a little bit sometimes. And it's causing the West and the world to really respond in such a forceful manner in a way where
I think it's interesting. There's simultaneously some level of overestimation and underestimation going on, it seems like, at the same time about China's capabilities. It's very easy. Obviously, you're evaluating. I mean, forget about evaluating LLM on 10 different metrics to figure out which one is better. I mean, imagine evaluating another culture, another country across like, oh, the miltech, the semiconductors, the social cohesion, the level of their education.
There's so many ways in which you could compare the strength of two different competing countries. So, of course, like you're going to have things that are all over the map where sometimes you say they're 10 feet tall. And actually, this is not one of their stronger attributes. And other times you're like, you don't think they can do X. In fact, they could do X, you know, 10 years ago. And now they can do X better than you. So it's all over the map. And I think one of the most interesting.
important things is for us analysts whoever whatever passes for the thought leadership in our military industrial complex and national security complex they have to be well calibrated if you're not well calibrated you could go to war overconfident thinking that's going to be easy and you get killed or you could be the other way where like you think the enemy is
10 feet tall and you fold before you should fold, right? So all of this is super important. And I honestly just don't think the intellectual, I mean, of course, you need several things. The ideal analyst would be somebody who speaks fluent Chinese, has been there.
has studied military history, technology, hard science, all of those things. And believe me, this intersection of those requirements that I just listed is very, very small. So basically, I kind of feel like Washington is flying blind at this point. Yeah, especially the going there and knowing the people part, right? If you look at the current generation of
China analysts, really, especially during the Trump administration. They had people like Michael Pillsbury who loved to talk about how he read Chinese and that was his competitive advantage where no one at the CIA could read Chinese besides him. It was just like really fanciful interpretations of Chinese idioms. But compared to the... One thing I just want to say, just to reinforce your point, is that when you think about the characters that you hear about, like Pillsbury, you hear about this guy, right? It means he is a policy entrepreneur, right?
Okay. He's not building a startup to sell a product. He's selling himself as a product. Right. Okay. So the way that guy wins is he gets invited to panels. He publishes stuff in foreign policy or other journals. And he gets, you know, eventually he'll have a high position in national security state or start his own consultancy, whatever it is. But he's an entrepreneur and he's selling just like everybody else. Okay. So just take that into account when you judge what these guys say.
On the other hand, for example, I just recently was, I don't know if you've heard of the Office of Net Assessment in the Pentagon. Yes. It's a very famous office, used to be run by Andy Marshall. And I was just talking to some analysts there. And those guys are the official think tank within the Pentagon that advises the Secretary of Defense. And they're very serious about trying to figure out what is going to happen, future trends in technology, drones, etc.
autonomous weapon systems, AI, China. They're trying to figure all this stuff out.
And you don't know who they are. They're like totally, you know, anonymous people, but they're the serious ones, right? The guys you hear about are basically, yeah, they're basically grifters, right? I mean, you know. I mean, I always lament, you know, the quality of maybe, and I know there are some, there are definitely people in the ministry who would know their stuff, but like the average quality compared to maybe the area of the China hands, where, you know, during World War II and immediately after during the, you know, kind of the
early cold war that generation of china experts were basically all children of foreign missionaries who were born and raised in china these were like white people who spoke china as a native language including the dialects they knew chinese people better than chinese people even knew themselves and that was like that level of understanding who led the nation at that time and that is obviously they were all persecuted later because of mccarthyism but it's long yeah i think as a class the people the government if i were advising president trump
and saying, who can give you good advice about what's happening in China and our competition with China and even extending to the MilTech side? I would say talk to American entrepreneurs who had to get their device manufactured in China.
So I interviewed a guy recently who he sells toys on Amazon, but all his stuff is made in China and he's been going there and visiting factories for over 10 years. He knows what's going on. He knows how the system works there. He knows how hard people work. He knows how competent the engineers are. He knows he can't get that stuff made at that price anywhere else. And maybe even at twice the price, he can't get it made in the US. Right. So.
Those are people who have the best insight. His Chinese is not perfect, but he certainly understands, you know, he's like 10 X, 100 X, some dude in Washington who sits in a cubicle. Right. So I would talk to those guys. The other point I want to make is that for students of history,
If you look at what people wrote in the Cold War, okay, what was happening during the Cold War? You had two very formidable superpowers, Soviet Union and the U.S., both of whom were pouring unprecedented amounts of money into developing satellites, thermonuclear weapons,
Intercontinental ballistic missiles. These were all computers. These were all driven by military competition between the two superpowers and the people who were analyzing and planning this strategic competition.
We're predominantly physicists. Okay. So, so this was an era where, you know, you, you went and got your physics PhD and then you became a cold warrior. Right. So the, the level of analysis is so much higher than what we see today. Now you'll never find even the people who are,
I find it so hilarious. I'll be reading some think tank report. Like I'm one of the only people in the country who reads these things. Like I'm reading some think tank report about some weapon system in China. And I, there's like two authors and I go and look up the authors. Right. And you're really lucky if one of those authors has a technical background, like an engineering degree. Right, right, right.
Sometimes the guys who wrote the article are both like political science. One guy's like a PhD in political science. You don't know anything. Like if you came and took my freshman physics class, you would probably fail. But here you are like telling me about some very intricate weapon system that where our guys are going to have to fight. Yeah. Right.
And this is what we have. This is what passes. In the old days, it's not like this. You got your PhD in physics at MIT, and then you went into the defense field. And then you became an analyst in the Office of Net Assessment or something. It's a totally different situation than what we have today. Yeah. I think one of your articles, you were talking about many world's hypothesis. Hugh Everett came up with it, right? And he, I think, had to drop his PhD to go into the military industrial complex because of issues with jobs. He left.
He left right after he finished his PhD at Princeton. He basically, yeah, he basically worked at the office of assessment. Actually, I think it was actually a slightly different office on analysis of systems. There was another office that was even more technical. But anyway, there's this night and day difference between the level of competency
competency today but i think china i think in china the people they have analyzing this shit are competent that's the thing is i think they have a much more realistic sense of what we're capable of than vice versa right well i mean i think china is definitely a society in general that values technical competence i think more than the u.s but i think if there are what i
notice is that basically developing countries, poor countries, value STEM more than humanities. Because humanities, in a sense, is a privilege, is an aristocratic discipline, right? To get to engage that kind of thing. We always knew in college that the wealthiest, on average, the wealthiest majors were the art history and the classics majors, right? Because the immigrants and the poor kids study engineering to climb the social ladder. And I think growing up in China, it was always clear that
Yeah, the smart kids with the highest Gockel scores, they go into STEM, the number ones still go to Tsinghua, but they go in as a philosophy and the literature majors. Yeah.
And I'm pretty sure his undergrad degree is non-technical. So you have some guy who went to law, like, oh, what's your qualification? Well, I mean, that's the whole US government, right? I mean, in America, that is the prestigious. What's your qualification for grand strategy in deciding like now is the moment to call an all-out chip war? Oh, I guess it's your law degree. I mean, really? Come on. No wonder they made such a colossal mistake in the chip war.
That's funny, because Jake Sullivan is probably, his background is like the golden poster boy of a US policy person's background, right? You know. The joke. You know, you could compare him to, for example, Henry Kissinger, who, although he didn't have a technical background, was legitimately super smart. And if you read
You know, if you read his senior thesis at Harvard, you realize this guy and lived through World War Two. So he understood a few things. But, you know, you can find examples of secretaries of defense and such who are literally like PhDs in physics and stuff like that. George Shultz. He was a he was a professor at MIT. He was an economics professor. But, you know, people like Harold Brown.
who was a physics PhD and later president of Caltech, and he was a secretary of defense. And compared to what we have now, it's like, come on, everybody now, you basically can't find any technical people doing these jobs. Well, so I wanted to get your thoughts on the value of the humanities, right? Like, you know, I actually am someone who does really value the humanities, and I didn't grow up without exposure growing up in China. So I always thought, you know, arts were dumb, you know, it was all just about STEM. And then I went to Yale, which is a very big liberal arts focused school, and I got
fell really in love with religious studies and history and philosophy. And I do find a lot of value in them. But over time, I think I have been trying to wrestle with whether we are fundamentally in the world where the technical disciplines, I mean, they clearly do make a bigger impact on society and whether, you know, these things that we've studied for thousands of years, they may still have some value, but they are actually diminishing in terms of, you know, how big, how much, yeah. Yeah.
I have nothing against the humanities as a subject. I think they're obviously, for example, just take an example. History is a great thing to study. If you want to think about great power competition or strategy, grand strategy, of course you should study history, but is it enough to only study history that I think it's necessary, but not sufficient. So anybody like say Harold Brown, you know, secretary of defense under, I think maybe Carter, um,
and a former high energy physicist, you know, like, do you think he went into that job and didn't like start reading a lot of books about Russia and the Soviet Union? And, and, you know, do you think he went in and just said like, nah, I don't need to know anything about history. I'm just going to do this job. No, of course he immersed himself and he probably reads twice as fast as, you know, your average history PhD. And if you know anything about, you know, psychometrics and, and,
So I'm sure he educated himself and said, like, well, surely I need to understand a lot of this historical background before I can opine on anything related to competition with the Soviets.
But you can do that. You can earn your PhD in physics and then go back and say like, oh, I didn't have time to read all these books on, you know, Chinese history, but now I'm going to do it. Whereas show me a Jake Sullivan who later on can have some intuition about exactly why hypersonic weapons are different from ordinary ballistic missiles. Like what, like,
How much intuition can he really gain late in life about these really complex questions or semiconductor physics? You know, extreme ultraviolet lithography. No way. No way. I mean, they were there. These guys are afraid to even discuss the subject. If they open their mouths, they immediately make fools of themselves. So in physics, we say or mathematics, we say the two the two operations don't commute.
You can't do A and then B. It's not the same as doing E and then A. You better do it in the right order. You better get your deep education in the hard stuff. Otherwise, you're not going to have it to rely on later in life. I mean, that basically is a Chinese intuition, right? Like you can go from one way to the other, but not back. Yeah. But here, everything's so politically correct. And, you know, like if a physicist
No physicist on campus other than like a guy like me would dare ever say stuff like that because then he would make an enemy in the history department and in campus politics, it would really be bad. It's a...
Nobody says anything. We live in a world where everybody's bullshitting all the time. It's all preference falsification all the time because things are so sensitive these days. And I definitely agree that on average, people who study theoretical physics are probably like two to three standard deviations of the average. So they do everything and they're basically successful. But I think one phenomenon I wanted to get your thoughts on was just the prodigious amounts of physicists going to finance and maybe now more AI research.
And I know in one of your blog posts, you know, talking about Charlie Munger and, you know, his pressured views on like Ricardo's comparative advantage with China. But the final quote you put on the blog post was your favorite about Charlie Munger lamenting the amount of hard science PCs are going to finance, how they're all getting brain trained. And in China, there's Shi Yigong, if you're familiar, right? He was, I think, dean of the Beida biology department is now the founding president of Westlake University, which is China's probably next generation research
Powerhouse University. And he also had a big speech where he lamented how, actually, I believe, counter to most people's expectations, the highest Gaokao scores in China don't actually go into physics or computer science. They go into finance. It's the most elite schools in Tsinghua, Beidou are their finance undergraduate majors. So it's also the top talent getting sucked into, you know, the highest paying, you know, money making jobs. And, you know, obviously he laments that as, you know, for a state and a civilization. I'm wondering your thoughts on it. Well, I agree with Munger. Munger said,
It's not good for society to attract your best talent into what is really a kind of zero-sum, he used the word casino, casino.
And it's not quite that bad because it's not exactly zero sum. Like you can make arguments about like having more liquidity in the markets is good. Having well-functioning markets is good. And it's a kind of underpinning technology for economic decision-making and allocation of resources. It's all true to a degree, but the extent to which a really talented person
can add value in finance, I think is dominated by people who do real positive some things in the technical world. And it is kind of good that people can now make more money in Silicon Valley. If you're a successful AI founder or something, it may dominate the career path of somebody who goes to Jane Street and just does little stupid arbitrage tricks all day. So
I have friends on all sides. I have friends who were trained in theoretical physics or math or computer science and went into finance and were really the first, the early generation that introduced quant techniques like derivatives pricing, options pricing, all that stuff, high-frequency trading. I was the TA in graduate school at Berkeley of a guy who built the whole HFT setup at Citadel and is a billionaire, okay? Yeah.
So I know all these guys, right? And I also know guys who are tech founders. First author on the scaling paper from OpenAI, high energy physics guy. So it gives me, it's such a rich tradition, physics. It's the first science that became truly international.
and attracted people, the glamour around physics after the Manhattan Project and Oppenheimer and all these things was so high that for generations, like the top people were sucked into physics. If you read Donald, do you know who Donald Knuth is? The guy who wrote The Art of Computer Programming. So if he writes in his autobiography, he says like, well, like every kid in my generation, Cold War generation, every kid in my Cold War generation, I was sucked into physics. And he started out at Caltech as a physics major.
But of course, he just ultimately realized he was more interested in discrete math and computers and stuff. So he ended up there. But the point is that at one time, everybody was sucked into this kind of education. And so coming from that tradition, I've seen people go in all directions, to hedge funds,
quant finance, trading into startups, you name it. They're all over the place, right? And I feel that
It is a misallocation of resources for too many people to go into quant finance. And I think now it's not as glamorous. Like, I guess it kind of went like this. Like, for a while, it was very glamorous. And then it kind of backed down a little bit. But now with Jane Street and some of these two sigma and stuff, it's kind of come back a little bit. But still, if you're really creative...
There are much greater things you can do, like founding a company or building a really earth-changing new technology. And I think that's a healthier way to distribute talent in society. Right. So then with the students you see then, are you doing anything to try to nudge them away from finance in a sense, right? You think it's misallocated, anything's too many. So I've been through this many times, either training a PhD student or a postdoc in my group. And I tell them like,
It's very tough to get a permanent position, a position where you're basically being paid to do research all the time. In theoretical physics, it's very tough. And you should just assume you're not going to make it. There was one period of time where they kept careful statistics. And even from the very top PhD programs like Princeton, Harvard, Berkeley, Stanford, Caltech, MIT, it was like maybe one in four.
one in five PhDs from those schools would find a permanent position. So it's not very many if you think about the quality of the people in these PhD programs. So I would just tell them, you're probably not going to make it. But luckily with me as your advisor, I have pretty broad interests. So if it looks like you're not going to make it, we'll spend six months, nine months at the end of your PhD or postdoc period where I'll train you up.
In something like options pricing theory or, you know, quant finance, or it could be in more machine learning type stuff so that you'll be more marketable on the job market. And so I've been through that with, you know, at least a half dozen students in postdoc, maybe more. And, and so I'm pretty familiar with that. Even that, like the psychology of that transition. Yeah.
between being really, really focused on having an academic career and wanting to do fundamental science to all of a sudden being like, hmm, what's my net present value for doing that? You know, that totally different way of thinking that these finance guys engage. I see it a lot too. One of my best friends, he is about to finish a math PhD at Sony Brook and he is at the point where he's tired of being poor and he's going to finance, you know, you know, realities. And look, I don't want anything against him, you know, of my
really closest friends, like guys who I was best man at their wedding and stuff like this. A lot of them are in finance at hedge funds and stuff like this. I don't hold anything against them. You know, life took them where it took them. And, you know, in the scheme of things, those were also fascinating careers too. I mean, they got to do a lot of interesting stuff. So,
In terms of base contribution to like the advancement of society or deep knowledge about the universe, of course, we don't want everybody to end up there. Do you think you were able to resist the temptation, right? And you didn't go to, you know, I, I thought about it and I actually spent a lot of time trying to understand financial markets, economics, you know, quant finance type stuff. I actually wrote the first paper, which was not published, but it was circulated around wall street. Um,
which used something called path integral. So there's a thing called the path integral, which Feynman introduced in quantum mechanics and has become like a big thing in quantum field theory. I used path integral methods to give closed form solutions for exotic options pricing values. And at the time, that was actually faster than the just purely Monte Carlo method people were using. So that actually...
was used by at least one or two trading groups for a while, but that work. So I actually came pretty close to going down that route. Actually, if you talk to my girlfriends from that era, they would be like, yeah, Steve was always undecided whether he should stay in physics or he should just go to Goldman Sachs or something. And I think what happened for me was my career just went in a certain path because I was a junior fellow at Harvard, which is a high prestige thing. And
So I kind of knew I could stay in physics if I wanted to. I didn't have to go through quite the job difficulties that most people, even PhDs from good universities have to go through because I kind of knew I was going to get a good faculty position. So that's kind of what kept me in. Also, you know, it's funny because if the ground zero for quant finance had been in the Bay Area instead of New York,
I probably would have gotten into quant fancy because I just don't like the Northeast. I don't like New York City. I never liked it. When I was a professor at Yale, I used to go down to New York City to hang out with my bond trader friends and shit or to train at Henzo Gracie's school, jujitsu school. That was the closest thing.
you know, BJJ school to New Haven at the time. So, but I used, I hate New York and just the idea that I have to live in Manhattan just never appealed to me. But if it had been in, if it could have been like, oh, you can live in Berkeley, California, you know, if, if, if the roles had been a little bit reversed and gone to finance, part of the thing repelling me from finance is I just did not want to live in Manhattan. Right. Right. I mean, yeah, to this day, I think most of these big, you know,
you know, quant firms aren't really in California, maybe due to non-compete reasons, but, you know, still isn't a big presence. I don't know why. I don't know why it is. Yeah, but it's just inertia. But yeah, that actually idiocratically played a big role. Right. But I guess, you know, you are now a professor and you've served in academic administration functions, but you still engage in private sector activities, right? You had genomic predictions and you now run Superfocus. Like, what is, you know, your interest in these private sector pursuits? And also, I'm wondering, honestly,
Do you feel like it detracts from research? So I got involved in tech startups over actually about 25 years ago. So during the first internet bubble and my first, the first company I founded was with a PhD student who was studying with me at Yale. And we started the company, you know, when he was still a PhD student and that became a company called SafeWeb, which was acquired by Symantec.
And so once I had that experience, which was so exciting, it's so exciting to like, actually the headquarters at first was in Berkeley and then we moved it to Emeryville, which is right next to the Bay Bridge, a little town on the East Bay, right next to the Bay Bridge. And so we had the classic startup experience. And once you understand that world, once you understand how venture capital works, how entrepreneurship works, how leadership of a team works,
All these things, it's like, it's kind of addictive because you have ideas and they can be ideas in a broader space than just like some narrow area of physics. You can actually do something about it. So if we figure out that like, wait a minute, there's enough data now to actually predict quantitative traits in genomics using machine learning, you can not only do it as a research project, you can build a company around it. So I've always, since then, I've always had my sort of one foot in one world and one foot in the other.
If you talk to my advisor, you know, at Berkeley or, you know, my colleagues, they'll be like, man, I wish Steve would quit fooling around with these stupid tech companies and just spend all his time doing physics. And then like, there are actually many times when like a particular venture fund was like,
Because I can't be the CEO of the company if I'm not full-time. So if I'm only involved as a professor, like I'm on the board and I'm helping the company, but I'm not actually the CEO. There have been times when I've had venture funds say, hey, we really want to put a big chunk of money into this company, but only if you're the CEO. And so-
it on both sides people have said yeah you should drop that other thing that's stupid why are you why are you writing these papers on black holes i just cut it out like come over here and help us make sure this product ships you know so but you i don't know but i so far haven't been willing to give up either right i haven't and part of it is my i think it's just hardwired polymathic nature because there are plenty of people who are
smart, very smart, but they're not polymathic. Like they just, they're able to just focus on one thing. Like I'm doing algebraic topology and I'm not going to even think about the next election. I'm just doing, you know, I'm not going to worry about, you know, my kids like school board. I'm just doing algebraic topology from now until I die. Right. So there are people like that.
hedgehogs, if you want to call them that. And then there are foxes who are always like sniffing around and finding interesting stuff or even like better, like you could say like hawks or eagles that fly above it and see interesting stuff and come down and look at it. So I just have that personality where I'm doing lots of stuff and I, I can get bored easily and I can get interested in something and I'm able to kind of go deep.
into something. And like, you could say like, Steve, why are you worried about us trying to geopolitics? That has nothing to do with startups. And it's the thing with physics. What the hell is that? Right. And it's like, yes, but I still spend a lot of time because I'm interested in it. And I ended up talking to people from the office of net assessment in the Pentagon, you know, or something like that, or at the Jason's or whatever. So I think that's just a hardwired aspect of my psychology that I have probably, you
Some of my colleagues would say your interests are too broad. You should not do all this stuff. No, I mean, I definitely am a believer in, you know, polymaths and Renaissance men and how, you know, I think empirically the foxes outdo the hedgehogs, at least in predictions. You know, like the world is interdisciplinary. It's complex. It's interdependent. You know, it might be true over some...
set of predictions. However, it might be that the ones who make the really deep time, you know, eternal contributions are the hedgehogs. So like Einstein didn't do much other than physics. So, so, so the thing is like, and maybe von Neumann, if he had focused more on one thing would have made some real, well, some mathematicians would say von Neumann, although he was very quick and smart, didn't make any one like really, really deep mathematical predictions.
the way that, you know, some other people did, right? Who were maybe not even as talented as him. So there is a trade-off going on here for sure. Yeah. And just to your point about like your interest in US-China geopolitics, and I'm kind of curious, you know, given your Chinese background in this day and age, you know, being interested in this field and maybe doing certain things with the US government, do you think you're
actually curious about whether your Chinese background played a role in shaping your identity growing up, or even now you face any additional resistance, you know, potentially with increasing geopolitical tensions? No. Well, it definitely played a role in shaping my view of the world, because certain questions that I regarded as fundamental, I was always astonished that other people were not interested in these questions. So
I would even ask my dad, like, well, wait, you guys keep saying you have 5,000 years of civilization. Well, what, what happened in the last few hundred years? Like what, what, what was that? You know, like how come you guys, you know,
You know, there's an untrue statement that like, oh, they didn't know the earth was round until the Europeans told them it was round. But that's actually not true. But that's a widely stated thing, even by like, quote, historians of China or whatever. And and but, you know, I would ask my dad, like, is this true? You guys with your great civilization didn't know the earth was round until the Europeans came. Some Jesuit missionaries came and told you like, what, really? So there are really some fundamental, deep, fundamental questions about
developments of society, progress in technology, economics, deep economic history. So there's stuff like that I've been interested in since literally I was like a five-year-old kid because it was kind of obvious. Some of these things are obvious to me from very early age. And so it definitely shaped my identity that I'm interested in these questions. And so I'll just give you an example. The first time I went to China was I think around 1991, I
I attended a conference in hierarchy physics in Japan. And so I was in Tokyo and I deliberately said, and I don't think you could go to China at that point, except the special economic zone across the border from Hong Kong.
And so I deliberately made a trip. I guess my girlfriend lived in Hong Kong. I had a girl, ex-girlfriend who lived in Hong Kong. Anyway, so I deliberately added a leg to my trip. And these are the days when international travel is much rarer than it is now. So anyway, so in addition to that physics conference in Japan, I deliberately went to Hong Kong not to see this girl, not to see my buddy who was trading for Salomon Brothers in Hong Kong at the time.
No, I went because I wanted to go across the border and see the special economic zone because I wanted to understand what big China, real China's trajectory, not Hong Kong or Taiwan, but real China's trajectory was likely to be during my lifetime.
And I remember people in Hong Kong, like my girlfriend saying, like ex-girlfriend saying, like, why are you going to Shenzhen? It wasn't even called that then. It was probably called that then, but it was mostly known in the West as a special economic zone, SEZ. And she was like, you should go to Guilin. You can go to Guilin. You can get like a one, a few day temporary passport and go to Guilin and see these oddly shaped limestone rocks. Right, right.
And I'm like, what the fuck do I want to see these rocks for? I'm going to go. I'm going to take this like horrible bus trip across the border to Shenzhen where they don't even have sidewalks. They just have mud and they're putting up skyscrapers and mud and then huge factories, huge infernal factories that scream of the early industrial revolution where people, you know, quality of life is horrible. Yeah.
People don't know how to behave in an, you know, organized industrial setting. People are poor. People are like six inches shorter than me because they had no protein to eat when they were growing up. No calcium, you know, just insane. I saw things that, you know, I will never forget. I wanted to see those things. And so obviously I had a deep interest in what was going to happen there. And so, yeah, I've had this interest for a long time now.
And to me, it's like if you just say, like, what's the greatest story of the world over the last 20 years? Well, it's obviously the development of China, right? It's like, okay.
You know, one fifth of the human population goes from being desperately poor to being one of the most technologically advanced countries in the world. How many times has that happened in the history of humanity? Well, maybe never. Right. And so that's the greatest story. And if you're like a historian or political scientist or whatever, and you missed it, well, too bad for you because I was following it. And so, but now we're finally at a point which I anticipated as a kid, because I knew what happened to the Japanese Americans and stuff like this, that
Yeah. I mean, there, I'm sure that, you know, I'm not sure there's a very good chance that NSA or, or CIA are monitoring my communications and people are like, is this Steve guy on our side or is he actually a spy? You know? And it's, it's very weird because as I've said in other interviews, I'm regularly talking to us national security people, intelligence people and stuff like this.
And I mean, just as a civilian, I don't do any spying for anybody. Sometimes people come to me and ask me like what I think about something. Right. And I'm regularly doing stuff like this. And yet, because I am ethnically black.
Chinese, there are plenty of people who will be suspicious that I'm actually a spy or something like that. Yeah, and it's inherently true. I think in this climate that our ethnicity does matter and it's noticeable versus like in the Cold War, the Russians were white and they could blend in a very different way, but we're noticeable. My interviewer for Yale, who was the U.S. Consul General in Shanghai and was on the National Security Council under Clinton Bush, he's a white Jewish guy married to
Chinese woman, was one of the first Americans to go to China. And he tells me that he married a Chinese woman. And nowadays, someone like him could never serve in the positions he did just because he married a Chinese person. It's just too sensitive now. Even though he's a white American, they just couldn't even place it there anymore. Yeah. So I think things are going to happen in the next 20 years, I'm pretty sure, because this competition is probably going to intensify.
And so, yeah, the part where the unpleasant, you know, up till now, it's just been an interesting intellectual exercise for me to follow what's been happening in China development. But now it could get kind of nasty. Who knows?
Yeah. I wanted to touch a bit about, you know, the genomic predictions work and, you know, your work with, you know, cognitive, you know, predictions, psychometrics. And so, you know, you've, you publish research showing, talking about the genetic architecture of intelligence and, you know, how we're getting to a point where we probably, you know, correct me if I'm wrong, maybe getting really close, we're already able to predict intelligence, you know, with polygenic, you know, genetic markers. Yeah. First, I'm kind of curious, like,
Where are we at in terms of the stage of like getting a baby or an embryo and just figuring out what is their IQ going to be? So can get the embryo, genotype the embryo. My company, Genomic Prediction, has genotype something like approaching 100,000 embryos. Right. You know, it's part of our business. And we get a whole genome genotype.
And from that, we can compute all kinds of things. Like if you're an outlier and risk for diabetes or breast cancer, et cetera, we can determine those things. We deliberately don't try to make any estimate of cognitive ability just because it's too controversial. If we did try with the current best cognitive ability predictors that we've built or other people have built,
you could maybe get a correlation of about 0.4. Okay. 0.3, 0.4 between the cognitive ability of the kid and the genetic, the eventual cognitive ability of the kid and the calculated genetic score. Right. 0.3, 0.4 is not
you know, it's not really good enough for, well, I mean, okay, like, Guern has done these calculations and other people have done these calculations where, like, you can get, depending on how many embryos you're choosing from, you can get a few IQ points out of this, the expectation value. Just the delta in expectation value is maybe not the most important thing. Like, you could also, like, with
pretty high probability exclude rare negative fluctuations. So in other words, you could reduce significantly the chance that your kid is in the bottom 5% or bottom 20%. Okay. You can do that. So it's funny because even like sophisticated, even like fairly sophisticated people who think about this don't really think about it properly. They only think about like, what's the expected gain, which really like for a family, like
The variance around that is pretty big. It's like the expected gain. Okay. It's important to know, but really what you'd like to know is can I like exclude some tail risk? And I have the hardest time explaining this to people that, you know, when you buy home insurance, you're paying some percentage of the value of your house every year for that home insurance. And most people never benefit from that home insurance. Right. So why do people do that?
Well, they do it to eliminate some tail risks they really don't like, like my house burns down. So in the same way, 0.3, 0.4 is not great, but I can eliminate a significant amount of tail risks that you don't like. And just based on that, a highly intelligent, rational person would understand there's a lot of value in this, right? Right.
The main limiting factor for improving these predictors is just the availability of data. So the political situation now is that if you go out and you try to, you're building a biobank or you're doing something and you try to measure the cognitive scores of the people that you're inducting into your sample.
You will just be attacked. They'll call you a racist. They'll call you a eugenicist. NIH is so scared about this, they won't touch it with a 10-foot pole. Nobody can get funded to do this kind of research. Even worse, NIH is banning some researchers. For example, some people that I've worked with before who are really world-class computational genomicists, statistical geneticists,
they are not allowed to access what data the NIH does have of this kind, right? So it's clearly a Sharia law reaction to a certain branch of science. This is a branch of science because when we build these genomic predictors for cognability and we find like, oh, there's this gene, a variation, this gene has some particular impact plus or minus on the expected IQ of the person,
Immediately, you can go back into neuroscience and say, oh, I see this gene codes for this protein, which is involved in this neurotransmitter or the growth of this dendrite. This is real science. It's not like bullshit. There's real stuff here, but we are not doing this science because some leftists...
have the butthurt feels. That's literally how our society is organized, right? So some leftists have the butthurt feels. So there's a very serious, important area of science, which we could make progress on, but we're deliberately not making science. And we're persecuting the people who are interested in it. Right. So basically right now in the West, there is actually no progress in enlarging this data set, right? It's just stagnant. It's just not getting... Well, I don't want to comment
too in too much detail because then I would shine the eye of Sauron on some researchers that are just trying to do science. So obviously like, oh, there might be incidental collection of genotypes. Maybe you can hoover up and aggregate those genotypes. Just I can't resist telling you the story. So there was a there's a longstanding collaboration which used to be based at UC San Diego and then it moved to USC in
It's called the Pediatric Imaging Neuroscience something. It's a project where they inducted lots of children and then they did a bunch of brain imaging on them, pediatric imaging. So they did a lot of brain imaging on these kids and they were studying the neural development of these kids. And of course, like even just old timey, old school neuroscientist people, you would IQ, you would measure the cognitive ability of these kids. Right.
as part of the project, right? Yeah. But that generated a data set that was very dangerous. And so like lately, there's been tons, if you look carefully in the scholarly literature, it's not really the scholarly literature, it's the butthurt, woke feels literature. There are people like, oh, this is really bad now because wow, we actually, from that data, and you know, by the way, like they were very responsible researchers. So they have like all the different American ancestry groups are in this
population sample. You have Asian kids, you have black kids, you have white kids, you have mixed race kids, you have everything in the sample, right? It's thousands of kids that were imaged this way over the years. And they have lots of data, bio data on these kids. So you can just take that data and trivially compute. There's a 0.4 correlation between just brain size and cognitive score.
And it's not brain size measured by craniometry, like some like old timey 18th century white guy with a mustache is like putting like calipers on my head. It's measured using MRI. You fucking idiots. Okay. It's measured by if you think I can measure like the size of little sub features of your brain and not measure the total volume. Really? That's what you think? No, I can measure the total volume.
I can measure the size of different features of your brain, and I can run tests to see whether in a statistically significant way, those gross physical measurements are correlated to the IQ, the cognitive scores of these kids. Lo and behold, yes, it's for real. There is a correlation. So what?
Well, very dangerous. Must shut this thing down immediately. You better shut this thing down, right? So that's the America that we live in. Right. So do you think like this kind of research is, you know, gaining speed in countries like China or other places that may not have these quants? Or like Singapore, which, you know, used to have eugenics programs. Not safe. There are many places where they don't have the feels reaction. Right.
That you would have here. So in other words, if I if I like my wife's in the humanities, if I was at some cocktail party, her department. And I just told the little story that I told you about the ping collaboration. I mean, ping collaboration probably burned like 100 million dollars of NIH money like this study over a decade. Right.
I mean, they accumulate a lot of good data, right? But, oh, it's dangerous, right? So if I went to my wife's cocktail party and told these English professors, history professors, political scientists, they would get very frightened. They would be shaking and they would be like, what? Brain signs? Stephen Jay Gould wrote a whole book on this, Steve. It's called The Mismeasure of Man. You should really read it, right? That's how they would react. Now,
The Asian professors in the group would probably be like, wow, this is really interesting, making a little mental note. So Stephen Jay Gould's book is bullshit, I guess. Wow, we were forced to read that in grad school. It's actually bullshit. Okay, anyway, so they don't have that kind of feels-y, visceral discomfort with the whole thing.
But even the scientists in China and Taiwan, a lot of them were trained here. They understand the sensitivities of their white colleagues. So they actually also have like a kind of stop short kind of instinct also. Like they're like, well, I understand there's a good scientific reason to do this project, but my white colleagues might not.
find this a little controversial. Right, right. So, unfortunately, that's crept in even in Asia. I see. So,
it's still retarded somewhat but to a lesser degree yeah than would be here that's unfortunate because i would have loved to test myself you know taking my current sample and just to know did i achieve my full genetic ability or did it's not accurate enough for you to tell something like that well you said right now it's point four but like like you know if we have more data right then maybe you know eventually well
in the fullness of time, maybe you could get it, like the correlation could be 0.7 or something, right? Or whatever. But you, yeah. There's still also clearly some variance or it could just be pure randomness, developmental randomness that is not controlled just by the DNA. So you'll never get rid of that. Right. Because I was just always curious whether environmental factors like lead exposure, microplastics, whatever, did I, am I like stupider than I needed to be? You know, I'm always just like, oh, you know. You'll never know. Yeah. But
Let's say another factor, because I'm not the tallest guy, is height. Height is something that's less controversial, and you guys have pretty good ability to predict. We pretty much stall height. So our uncertainty in the height predictor is a few centimeters. So I could go get tested and know whether I was malnourished as a kid and was deprived of my full potential in height? I think in the extreme case where you were very malnourished,
then we could tell that in a quantitative way, but you would probably already know it. Right, right. Yeah. Most likely not extremely malnourished. Yeah. But, you know, I'll tell you something. This is, again, something that kind of dumb HPDers don't understand is that if you go to Japan or China until recently, or Korea, people really didn't drink any dairy and they had very limited sources of calcium in their diet.
And also like the average amount of protein consumed per day was way lower than what, say, Americans would eat. So, you know, like if you look at Korea, the kids are so much bigger now than just one generation, one and a half generations ago. Clearly, there is a lot of environmental stuff. And I don't think we really know the asymptotic kind of group.
Average height for East Asians, because even now there are that populations that are eating a kind of completely comparable diet to what they would eat in, you know, the Netherlands or something like this. Right. Or or Iowa. Right. So so there's still some residual uncertainty like that.
Well, there's that. And I feel like there's also, you know, social selection factors, you know, at least in East Asia. I'm just reading reports coming out of China of like, obviously the East Asians compete on everything that can be competed on. And now Haidt is like the new battleground. Her parents are so anxious about, you know, injecting their kids with human growth hormones, just like do whatever they can because they don't lose out on high competition. I think that's also going to push the average higher, you know, marriage selection, things like that. Yeah. I'm kind of curious. So,
You wrote a lot of the many, many worlds interpretation of quantum mechanics. And I'm wondering, you know, do you have any views on determinism and free will, you know, especially after the discovery of quantum mechanics or in a way that, or what does it even mean, you know, for you? Yeah. So I have written on this topic. I don't know if you saw my blog post on this, but so there's, there's sort of two separate issues here. So, so one is like, given what we know about physics, right.
What can we say about free will? And first of all, of course, it's very tough to define what you mean by free will, right? But I can define, to me at least, some philosophers don't like this way of viewing it. I think there's a school of thought called compatibilist. Philosophers who think about free will, some of them are compatibilists. I think that's all pretty stupid myself. But if you think in physics that
Forget about just your brain making decisions. Just take a slice, a time slice of the universe and ask if you have full knowledge of the position and momentum of every particle on that slice, can you predict the next slice, the state of the universe on the next time slice next time? So can you basically, if you think about partial differential equations, is there an initial value problem that you can integrate up?
And if the answer is yes, then what are you talking about? Free will? Like, what do you mean by free? You know, because the whole universe is deterministic. Yeah. Right. Then you can say like, well, but what about quantum mechanics? I mean, are there random events? Are there random outcomes due to quantum mechanics? And the answer might be yes. There's occasionally dice throwing going on.
But it turns out the operation of your brain is not intrinsically very quantum mechanical. And furthermore, if these are truly random dice rolls, in what sense does that give you a free will? Like if I have a robot, occasionally it is a robot, deterministic robot, but every now and then I perturb it using a random throw of the dice. How is that free will? So there isn't really any way to accommodate, I think, the traditional idea of free will, which is that like,
I have a soul and I quote, make decisions in the ether and this machine, meat machine then like acts on my decisions. One way to realize this would be like, we live in a simulation, right?
You are not an NPC. You're actually a player character. And in some higher dimensional other universe, there is a player operating you. Right. And in that sense, you have free will. Right. But that player may be determined, right? Because they're in a universe. Well, that's it. Okay. Who knows what the laws of physics for that player are, right? But that's a scenario where you could say like, okay, you're
The PCs have free will, the NPCs don't have free will, and that's the end of the story. So there's a situation where you could say, at least Majulo, what is going on in this other universe? The PCs could have at least more free will than the NPCs. So you can address it that way. There's no evidence in physics that I'm more than just a machine.
um that's described by this entire slice of the time slice of the universe and so therefore if if there's a good initial value description of yeah the universe there's a good initial value description of me plus my environment and therefore i quote don't have well and some philosopher guys gonna go like well this is the compatibilist situation it could be compatible i don't really care i think i think that's a my way of thinking about is more clear i think than yeah anyway i mean but
Go ahead. Go ahead. Your position is basically my position. You know, since learning about physics, I find it difficult to believe in free will. And I'm kind of curious, like, how does this impact your day-to-day life, right? You know, are you bothered by it that way? Or is it just the illusion of your agency is enough? Well, yeah, I think ultimately when you think about it,
We are an evolved species, and it's useful for evolutionary purposes for us to have the illusion of free will, the illusion of self, the illusion of making decisions, even though they're determined by some lower-level machinery in our neural net. Those are all still useful illusions of self and self.
agency that we have but possibly they're just illusions yeah right so just it is what i mean that so maybe that that's a very like dispirited for some people for some humanists for example it's a very dispiriting perspective but that could be true it's also possible we're in a simulation and i'm an npc and you're not it's so so that's also possible no yeah
Yeah, I don't, I enjoy discussing this stuff, but I can't imagine spending like a significant amount of my entire career at like a philosopher would working on this stuff. It's kind of laughable, but because the basic things are not known, like you got to figure out the actual physics, you know. By the way, I just want to say one other thing, which is that another deep aspect of physics, which is even more deep in a way, it's not as personal for humans, but it's even more deep, is
is there actually true randomness in physics? So that's a really fundamental question, which actually I have to say most physicists are, most physicists kind of punted because of this stupid Copenhagen interpretation of quantum mechanics. They just punted and said, yes, there is true randomness. I accept it. There's true randomness. But actually it's not clear. Whatever it showed us is that
In fact, it could be that the wave function as a whole is evolving purely deterministically and there's only apparent randomness to the individual observers on branches of the wave function. But that is, in a way, the most fundamental question in physics. And yet, 95% of physicists that you talk to don't really understand this point because they just sort of learned something about the Copenhagen interpretation when they took quantum mechanics and they haven't thought deeply enough about this. Right.
Right, right. Or maybe they're too scared to know the truth, you know?
No, I, well, I think it's just sad that, I mean, if you look at the sociology of physics, this Copenhagen interpretation thing is just the most convenient way to formulate it for students. So we can just get on with calculating, calculating cross sections and reaction rates, because that's much more important. That's kind of the way the field went. And then it's like only a small number of deep thinking people went back and looked at these things more carefully, including Everett. Right. Then like that knowledge is very esoteric, even within physics. Interesting.
So right now, the Copenhagen Interpretation is the consensus view that's really taught in the many ways it's a heterodox? Well, the funny thing is it's a kind of consensus view among the bulk of the physics population that has not thought deeply about this question, which is most people. And among the people who have thought deeply about it, I would say not that many believe in Copenhagen. I actually document this on my blog. I've gone back and looked all over.
the biggest brains, all the top theorists, you know, going back a couple of generations and tried to see how many of them actually thought about this and wrote down their thoughts about
And overwhelmingly, you can see that, you know, whether it's Julian Schwinger or Richard Feynman or Murray Gelman or, you know, you name it, David Deutsch. Well, I wouldn't necessarily put Deutsch in the category with those guys. But every one of them, if you look at their, if you look carefully at what they wrote, because there was a very big social stigma about talking about Everett or deviating from Copenhagen for a long time.
Nevertheless, you can find in their writings, I document this on my blog for, you know, huge number of these people. They were very specific about this point that like Copenhagen doesn't make any sense. Everett does seem to be self-consistent, although we don't know for sure that it's correct, but it does seem to be self-consistent. And boy, my colleagues are dumb and I can't believe they didn't think harder about this.
So why hasn't this trickled down to the standard curriculum? Yeah, I'm sure there's lag, but like, you know, why is it still not that this is what's being taught in school?
Um, because it's off the track of the way you advance your career in physics. So it's kind of irrelevant to the actual experiments that people do in physics to learn a little bit more about the fundamental laws or the mass of some particle or the properties of some semiconductor. It's all kind of irrelevant to that. It's a much deeper foundational question.
it's sort of hived off into an area called quantum foundations. But if you realize, if you have a slight philosophical bent or whatever, you realize this is like the most, one of the most foundational questions in physics. And it's kind of amazing that if you just pull like a hundred random physics professors, most of them have not thought deeply about it. It's very frustrating to me. I mean, I've written many papers on this kind of stuff, but, but,
It's a sociological phenomenon. Right, right. And I wanted to touch on something you mentioned earlier as we were talking about free will, you know, about the role of religion. I'm kind of curious, are you religious and do you have any views on, you know, religion? Yeah, this is a great question. So my mother...
Her family, actually this military family, they were converted to Christianity in the 1800s by missionaries. Wow. So it's very unusual that I come from this long line of Christians. My mother is a devout Christian. I was raised as a Methodist. So at the age of like nine, I pleaded with my dad to accept Jesus Christ as
So that his soul, he would not, his soul could go to heaven and he would not burn in hell. Right. So I would say I have a very deep religious sensibility. I can very easily, if I walk into a church and I listened to them singing, or I walk into a beautiful cathedral in Europe and look up, I can easily attain that mindset where I think,
There is more than just this visible physical world. There's a depth to the universe that humans will never fully grasp. I can empathize with all of that. However, I also have the smart-ass physicist's perspective that like, yeah, this is just a kind of like weird delusion that heaps have. They can't accept death or that they're a machine or that the free will is an illusion. So they punt and say like, oh, the universe is mysterious and God loves me.
So I can kind of have both perspectives. It's kind of strange. That's interesting. I understand what you're saying, you know, just rationally, right? You like just how you talk about if you will. It's hard to believe in this non-materialist soul-ish thing going on. It just doesn't really make sense. Yeah. But just the fact that, you know, when you walk into a church and you do feel something tugging your heartstrings, maybe that's a sign of
you know, something going on there where obviously there's material ways to explain it, but there's, I, I also feel that I'm the same person that grew up in Ames, Iowa, you know, 40, 50 years ago, even though every molecule has been replaced now in my body. Right. Right. Yeah. That's a useful illusion from the perspective of evolution that I feel that way. So,
Yeah. And, you know, as we get close to wrapping up, I'm kind of curious, are there any things you thought really intentionally about when it comes to educating your kids? You know, I did. I was I was a very high. My kids are in college now, so it's kind of over. It's really a weird milestone in your life to think like invested so much energy and time.
I didn't necessarily do the right thing all the time, you know, I, but I tried and it's, it's an emotional thing to like realize it's over now. Like, of course I still have some influence, but you know, it's decaying exponentially, you know, once they move out of your house. So I tried to be like, like I tried to teach my kids stuff. Um, uh, I'm,
I think this is a common thing, actually, among physicists. It was funny because at our AI company, Superfocus, where my son is working this summer,
There's another kid there who's also the son of another physicist that a colleague of mine. And so they're both interns there. And I was asking them about it and they're like, yeah, both in both cases, like dad tried to teach me all this stuff when I was a kid and like, you know, probably probably ruined my interest in physics or something or math or whatever. So I tried. I think what I would advise parents is expose your kids to lots of stuff.
A little bit of what you're doing is providing the kid the willpower that he doesn't have because his brain is still maturing. So don't let him quit immediately, like expose him to something and make him try. Sometimes you have to just make them do stuff. It's good for them. You don't want to push it too far and create a nonlinear back reaction. But a lot of the times you're just thinking like, it's good if my kid learns jujitsu. It's good if he learns how to swim well.
And for a while, it's going to be me supplying the willpower because the kid doesn't want to do it. The kid would rather just be watching TV or TikTok or whatever. But I'm taking them to the pool and I'm making them swim. So you can do some of that, but you can't push it too far or maybe you're going to have the opposite effect on your kid. And so that's all I can say to people is that. Right. So are kids interested in physics at all?
Yeah, my daughter's more on the artistic side, so she's not. And my son is actually pretty talented in math and stuff like that. But he's a computer science major. And I think it's actually unfortunate that he's not studying more physics in college. He took some pretty advanced math and physics when he was in high school. He had already taken like the college calculus based physics class. He had taken linear algebra, multivariable calculus in high school.
And he's thinking he's definitely going to take more advanced math, but maybe more along computer science lines and less along physics lines. So in a way, it's kind of tragic. Like he may be one of those people who will never really understand Maxwell's equations. Right. I mean, but like you mentioned, right, oftentimes kids have some level of rebellion to, you know, what their parents' vocation is maybe. And, you know, sometimes also when they get older, they come around. I think about how like
My dad is a professor of pharmaceutical oncology, the Chinese Academy of Sciences. And probably the thing I've always been least interested in and know the least is anything related to life science or biology. Everything else I'll learn, but just not the biology. And there's some maybe inherent thing there about trying to leave your parents' shadow, right? Given you're such an eminent physicist. Yeah. So that could be an unfortunate consequence of it. So parenting is one of these weird things where you just have to acknowledge at the end
you really can't evaluate the counterfactual very well. Like my wife will say things like, oh my God, we should have kept them in piano for another year or we should have forced them, my daughter to learn violin longer. You know, I'm like, well, how do you know what, you know, the consequence of that would have been?
You know, you'll never know. I mean, so many things I think it's quite hard to evaluate the counterfactual. As someone who's interested in Chinese history, I'm always thinking about the counterfactual, right? What are the KMT-1? What are this list? Who knows? You know, there's romanticized versions of a different trajectory, but it's really hard to say. I certainly couldn't tell you how my life would have turned out if I had, you know, taken the offer from, you know, Morgan Stanley to join their company.
quant trading group when I was 25, you know, or 24 or whatever. I didn't do it, but I can't tell you what my life would have been like if I had done it. Right, right. Maybe final question for you. I'm kind of, you did write some topics about happiness in your blog, and I am curious to hear, what is your main approach to happiness? Again, it's a very hardwired thing. I'm just a pretty happy person. Like, I'm very lucky. I don't have, I'm not high strung or neurotic. I don't have
problems with depression. I'm pretty much happy all the time. I'm so happy, I'm probably annoying to people. I wake up in the morning and I'm just like, hey, what are we doing today? What's up with that? And then they're like, oh my God, leave me alone. So I don't have much to say other than it's hardwired. I will say one thing, my dad was old when he had me and my brother. And so the whole time growing up, I thought being a smart kid
and no understanding death, like having thought a lot about death and infinity and stuff like this. I was like, wow, there's going to be a time when my dad is not around. And since he's older, I can like kind of calculate, like I'm not going to be, potentially I'm not going to be that old when he goes. And so when my dad died and I was in my mid thirties, I think really affected me because I mean, I have friends who are my age and both parents are still alive. It's not that uncommon. Whereas my dad's been dead for a long time.
And when that happens, you then can consider someone's life in its entirety, someone you knew really well. You can think about like, well, what was important to my dad? Like he had an academic career, he published books, he wrote scientific articles, but what was really important to him, it turns out it was family.
And so, like, I always have this balance, like some of my physicist friends who are very focused on their physics careers or whatever guys try to make money. I've always been like, you know what, there's a good chance at the end, like all this stuff is you're going to regard this all as kind of like vanity bullshit, like, you know, vanity, vanity, all is, you know, the.
from the Bible, you're going to realize it's really your family and your human connections that matter. And in that way, actually, the experience of having kids and raising them has been such a joyful and rewarding experience that in a way, some people might say, oh, this Steve guy, he's such an elitist. He's talking about cognitive ability and Richard Feynman and whatever. I actually am glad that almost any ordinary human
who can have a family and raise their children really has experienced maybe 90% of the great stuff. You know, even if they were working as a gardener the whole time, they didn't have some highfalutin career. They still got to experience really the great stuff. And I feel that's, you know, it's a, in a way that's so contributing a little bit to the justice of the universe. And it, after going through that myself, I feel much better that,
things are not as unequal as they could be. Right. It's almost a religious view, you know, like on the blessing of children and how important it is. Like, I mean, you've accomplished so much and yet you say all of that is squeezed into maybe 10% of the happiness and value, you know, of life, right? In a way, in a way, yeah. I mean, of course, you can go into some mode where you're like, oh, what are my historical contributions to, you know, blah, blah, blah. But at the feels level, at some deep level, it's more like,
No, that other stuff is just vanity, vanity, all this. But anyway. Yeah. Well, thank you so much for your time, Steve. And I'm wondering, you know, just the audience, you know, you do write prolifically on Twitter and blogs. And so where can people find you? And I'm happy to leave. Well, I moved my blog to Substack. So just find me there. My place to start is just Twitter and my podcast, which is called Manifold. Yeah. Awesome. Well, thank you so much for your time, Steve. Thank you.
