Richard Hanania and Steve Sailer: noticing the kakistocracy
2w ago00:29:53Tap to summarizeThis is a free preview of a paid episode. To hear more, visit www.razibkhan.comOn 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.

Brianna Wu: the case for liberalism
May 3000:20:01Tap to summarizeThis is a free preview of a paid episode. To hear more, visit www.razibkhan.comOn this episode of Unsupervised Learning Razib talks to Brianna Wu.

Nikolai Yakovenko: 4 years into the age of AI
May 1501:20:00Tap to summarizeIt’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. This is a public episode.
