US, China, AI & More - Dan Wang 2025 Letter

Dan Wang 2025 letter as usual is full of insights plus its funny when he pokes at Paypal mafia morons.

Narrowness of mind is something that makes me uneasy about the tech world. Effective altruists, for example, began with sound ideas like concern for animal welfare as well as cost-benefit analyses for charitable giving. But these solid premises have launched some of its members towards intellectual worlds very distant from moral intuitions that most people hold; they’ve also sent a few into jail. The well-rounded type might struggle to stand out relative to people who are exceptionally talented in a technical domain. Hedge fund managers have views about the price of oil, interest rates, a reliably obscure historical episode, and a thousand other things. Tech titans more obsessively pursue a few ideas — as Elon Musk has on electric vehicles and space launches — rather than developing a robust model of the world.

So the 20-year-olds who accompanied Mr. Musk into the Department of Government Efficiency did not, I would say, distinguish themselves with their judiciousness. The Bay Area has all sorts of autistic tendencies. Though Silicon Valley values the ability to move fast, the rest of society has paid more attention to instances in which tech wants to break things. It is not surprising that hardcore contingents on both the left and the right have developed hostility to most everything that emerges from Silicon Valley.

One of the things I like about the finance industry is that it might be better at encouraging diverse opinions. Portfolio managers want to be right on average, but everyone is wrong three times a day before breakfast. So they relentlessly seek new information sources; consensus is rare, since there are always contrarians betting against the rest of the market. Tech cares less for dissent. Its movements are more herdlike, in which companies and startups chase one big technology at a time. Startups don’t need dissent; they want workers who can grind until the network effects kick in. VCs don’t like dissent, showing again and again that many have thin skins. That contributes to a culture I think of as Silicon Valley’s soft Leninism. When political winds shift, most people fall in line, most prominently this year as many tech voices embraced the right. 

The two most insular cities I’ve lived in are San Francisco and Beijing. They are places where people are willing to risk apocalypse every day in order to reach utopia. Though Beijing is open only to a narrow slice of newcomers — the young, smart, and Han — its elites must think about the rest of the country and the rest of the world. San Francisco is more open, but when people move there, they stop thinking about the world at large. Tech folks may be the worst-traveled segment of American elites. People stop themselves from leaving in part because they can correctly claim to live in one of the most naturally beautiful corners of the world, in part because they feel they should not tear themselves away from inventing the future. More than any other topic, I’m bewildered by the way that Silicon Valley talks about AI.

[---]

It’s easy for conversations in San Francisco to collapse into AI. At a party, someone told me that we no longer have to worry about the future of manufacturing. Why not? “Because AI will solve it for us.” At another, I heard someone say the same thing about climate change. One of the questions I receive most frequently anywhere is when Beijing intends to seize Taiwan. But only in San Francisco do people insist that Beijing wants Taiwan for its production of AI chips. In vain do I protest that there are historical and geopolitical reasons motivating the desire, that chip fabs cannot be violently seized, and anyway that Beijing has coveted Taiwan for approximately seven decades before people were talking about AI.

By being the site of production, they have a keen sense of how to make technical improvements all the time. American scientists may be world leaders in dreaming up new ideas. But American manufacturers have been poor at building industries around these ideas. The history books point out that Bell Labs invented the first solar cell in 1957; today, the lab no longer exists while the solar industry moved to Germany and then to China. While Chinese universities have grown more capable at producing new ideas, it’s not clear that the American manufacturing base has grown stronger at commercializing new inventions.

So here’s a potential way that China succeeds. Beijing’s goal is to make nearly every important product in the world, while everyone else supplies its commodities and services. By making the country mostly self-sufficient, and by vigorously policing the outputs of LLMs and social media, Xi might hope to make China resilient. He is building Fortress China stone by stone in order to outlast the adversary. Beijing doesn’t have to replicate American diplomatic, cultural, and financial superpowerdom. It might hope that its prowess in advanced manufacturing might deter the US. And its success in manufacturing might directly destabilize the US: by delivering the coup de grace to the rustbelt, the US might shed a few million more manufacturing jobs over the next decade. The job losses combined with AI psychosis, social media, and all the problems with phones could make national politics meaningfully worse.

I don’t think this scenario is likely to be successful. Authoritarian systems have always hoped for the implosion of liberal democracies, while it is the liberal democracies that have a better track record of endurance. But I also don’t think that authoritarian countries are obviously wrong to bet that western polarization will get worse. So it’s up to the US and Europe to show that they can hold on to their values while absorbing the technological changes coming their way.

I wish that the tech world could learn to present broader cultural appeal. I hope that Silicon Valley could learn some of the humorousness of New York (or at least LA.) It’s unfortunate that any show or movie made about Silicon Valley is full of awkward nerds; by contrast, Hollywood reliably finds attractive leads when it makes movies about Wall Street. So long as the tech world is talking about the Machine God and the Antichrist, so long as it declines to read more broadly, so long as it is mostly inward looking, it will continue to alienate big parts of the world.
