Alex Karp: Silicon Valley Broke Its Promise to America
About this podcast
Whose imagination do you want to live in? In this new series, bestselling biographer Walter Isaacson sits down with the most consequential names in AI and tech to understand the futures they're racing to build. Elon Musk, Peter Thiel, Alex Karp, Fei-Fei Li, Dario and Daniela Amodei, and more open up about their ambitions, what frightens them, how they think about humanity, and what drives them to build so big and so fast. The conversations are intimate, charming, and sometimes chilling. But mostly, they're impossible to dismiss. Because whether or not you agree with them, it's their imagination we're all starting to live in.
