About this episode
Reid and Aria discuss the enduring significance of San Francisco and New York in tech, the future of AI in biotech, and the implications for free speech in America.
In this episode, Reid and Aria are live from New York as they unpack why predictions about the “death” of San Francisco and New York keep missing the mark and how network effects continue to anchor these cities as the world’s leading tech and finance hubs. Reid also shares advice for young founders choosing where to build and explains how to align your startup with the right economic network by breaking down lessons from companies like Shopify and Spotify that scaled outside Silicon Valley. The conversation then shifts to the future of AI in biotech as Reid offers an update on Manas AI and why curing disease hinges on regulation as much as technological breakthroughs. The episode closes with a candid discussion on media, political pressure, and the dangers of “pre-obeying” authority. Reid reflects on free speech, institutional courage, and what a volatile post-midterm landscape could mean for American democracy.
