On this episode, Razib talks to Daniel Di Martino, a Venezuelan-born economist, speaker, and fellow at the Manhattan Institute, where his research centers on immigration policy, including selection, assimilation, and high-skilled migration. Born in 1999 and raised in Venezuela, he witnessed firsthand the impacts of socialism, including hyperinflation and shortages, which prompted him to immigrate to the United States in 2016. He earned a BA in Quantitative Economics from Indiana University and a PhD in Economics from Columbia University. He writes for publications such as City Journal, and USA Today, and serves on the board of advisors for Young America’s Foundation while sitting on New Jersey’s advisory committee to the U.S. Commission on Civil Rights.

First, they talk about the economic and social impact of socialism in Venezuela under Hugo Chavez and Nicolas Maduro. Di Martino describes the country’s decline, including hyperinflation, shortages, and corruption, leading to a significant emigration of 30% of the population. Di Martino also discusses the potential for Venezuela’s freedom under the Trump administration and his ongoing work on immigration and economic policy. He advocates for a selective, high-skilled immigration policy in the U.S., emphasizing its economic benefits and the need for a moral approach to enforcement. They discuss Di Martino’s report, The Fiscal Impact of Immigration, and how Indians in America fit into that picture more precisely.

On this episode of Unsupervised Learning we have a double-feature with Richard Hanania and Steve Sailer. Hanania holds a law degree from the University of Chicago and a PhD in political science from UCLA, and was previously a research fellow at Columbia University’s Saltzman Institute of War and Peace Studies. He founded the Center for the Study of Partisanship and Ideology (CSPI) and writes the popular Substack newsletter Richard Hanania’s Newsletter, where he covers politics, foreign policy, and social science from a heterodox, broadly libertarian-leaning perspective; his book The Origins of Woke argued that civil rights law, rather than culture alone, drives modern identity politics. His latest book is Kakistocracy: Why Populism Ends in Disaster.

Steve Sailer is an American journalist and blogger, born in 1958 in Los Angeles, who worked in market research before turning to full-time writing in the 1990s, contributing to National Review, The American Conservative, Taki’s Magazine, and the webzine VDARE, as well as his long-running personal blog. He is best known for coining the term “human biodiversity” (HBD) and for pioneering a data-heavy style of commentary on race, immigration, IQ, crime, and demographics. This approach made him persona non grata in mainstream outlets. Long relegated to the fringes and often labeled a race-science promoter by critics, he published an anthology, Noticing, in 2024.

In the first hour, Razib and Hanania discuss his career, his use of social media, and his new book. They delve into the rise of populism, defining it as a movement that divides society into righteous masses and corrupt elites. Hanania argues that populism often leads to poor economic performance and authoritarianism. They also touch on the impact of AI on the legal profession, the role of social media in amplifying fringe views, and the challenges of immigration and institutional trust. Hanania expresses a preference for a merit-based immigration system and criticizes the identitarian deference on both the left and right. In the second hour, Razib and Sailer discuss the demographic and economic changes in Southern California, highlighting the impact of Latino immigration and the rise of new immigrant groups from the former Soviet Union. They recount the environmental movement’s role in halting development in Beverly Hills and the potential of robot taxis to transform urban commuting. Sailer reflects on the decline of Chicago’s Fortune 500 companies and the challenges faced by cities built on water transport. They also discuss the evolution of race and IQ debates and the importance of affirmative action in diverse fields. Likely to the surprise of many Sailer defends affirmative action for black Americans. He also expresses optimism for the future, despite the current political climate.

On this episode of Unsupervised Learning Razib talks to Brianna Wu. Wu is an American video game developer, programmer, and political activist best known as the co-founder and CEO of the independent game studio Giant Spacekat. Raised in Hattiesburg, Mississippi, she attended the University of Mississippi to study journalism and political science but withdrew in 2001 without earning a degree in order to pursue early entrepreneurial ventures. After establishing herself in the tech industry and leading the development of the 2014 indie game Revolution 60, Wu became a prominent advocate for marginalized groups in gaming, a role that expanded significantly after she was targeted during the Gamergate harassment campaign. She later transitioned into political organizing, running for the U.S. House of Representatives in Massachusetts as a Democrat in 2018 and 2020, and co-founding Rebellion PAC to support progressive political initiatives. In the last few years Wu has been pivoting more toward the center, expressing concerns about the power of the anti-Israel faction on the Left.

Razib and Wu discuss their political differences, he, being on the political Right his whole adult life, and, Wu, a partisan of the Left. Wu makes the affirmative case for a liberal Left vision of American politics, a welfare state without express support for socialism. They also discuss the excesses of both the woke Left and the MAGA Right, and Wu challenges Razib on the actions of state-level Republicans. She argues that for many Americans the Right presents no option, because it does not welcome many identity categories as the Left does.

It’s been a minute since we’ve had Nikolai Yakovenko on the podcast. Yakovenko is a former professional poker player,and was a research scientist at Google, Twitter and Nvidia. With a decade in computer science, Yakovenko has been at the forefront of the large-language-model revolution that has driven to prominence companies like OpenAI, Anthropic, and DeepMind, and an ecosystem that has birthed hundreds of smaller startups. He is also the founder of DeepNewz, an AI-driven news startup.

Razib and Yakovenko have been discussing the Age of AI for about 4 years now, and it’s time for a temperature check. Nearly four years ago, Razib put in a “prompt” that generated the below image:

The same prompt now returns the image at the top of this post. It illustrates the strides that AI has made in the last four years.

On this podcast, Razib and Yakovenko talk about the current top of the line “frontier labs,” OpenAI, Anthropic, and Google’s DeepMind, why xAI has faltered, and the reality that only DeepSeek in China seems up to challenging the American firms. Yakovenko notes that AI’s transformative impact is mostly in the massive capital influx into the sector, as well as becoming a ubiquitous part of the software engineer’s toolkit. They discuss how programming without an AI-assist is now likened to “raw dogging” coding, while artificial superintelligence seems a rather distant prospect. The technology is getting better, but predictions of the doomers seem not to have panned out.

On this episode of Unsupervised Learning, Razib talks to physicist Gregory Cochran. Cochran is best known for his work in human evolution, often at the intersection of biology, anthropology, and history. Trained in physics, he later turned to population genetics and became widely known through collaborations with researchers like Henry Harpending, producing influential but controversial work on recent human evolution, including the idea that natural selection has accelerated in the Holocene. Cochran has also been a prominent public intellectual, co-authoring the book The 10,000 Year Explosion: How Civilization Accelerated Human Evolution. He writes at the blog West Hunter.

First, Razib and Cochran examine the controversy surrounding Ancient DNA reveals pervasive directional selection across West Eurasia, including Davide Piffer’s complaint that the authors did not cite his work. Then, they review chapter-by-chapter the arguments in The 10,000 Year Explosion, from Cochran and John Hawks’ prediction that Neanderthals likely admixed with modern humans, to the importance of agriculture in driving adaptation in human beings and the ecological context of the increase in Ashkenazi intelligence.

Today Razib talks to Matthew Schmitz, a journalist who previously served as an editor at the religious journal First Things. He is the cofounder of the online magazine Compact, alongside Edwin Aponte and Sohrab Ahmari. He currently serves as editor of Compact, religion editor of Washington Post Opinions, and co-host of the podcast Against the Grain. Compact His essays on politics and culture have appeared in The New York Times, The Wall Street Journal, and The Claremont Review of Books. A native of O’Neill, Nebraska, Schmitz is a graduate of Princeton University.

First, they discuss Schmitz’s piece in the Washington Post, The unreligious religiosity of Christian identity politics. Here Schmitz articulates the view that the nationalist-inflected Christianity exemplified by many MAGA and MAGA-adjacent figures is quite different from the sincere but earnest evangelicalism of the older religious right. Rather, it is more performative, more civilizational, and tied into white identity politics. Additionally, it turns away from the philo-Semitism that has been typical of the American religious landscape. Schmitz and Razib also address the rise and fall of the New Atheism over the last 20 years, from the decline of public Christian faith as the center of the body politic, the rationalist critique and the marginalization of both by woke social-justice political theology. They also discuss the difficulties and travails of religious pluralism in the US today, including the tensions caused by the arrival of large numbers of Hindus in places like Texas, where they erect statues to their gods, including the semi-monkey divinity Hanuman.
