The Builders

iHeartPodcasts and Kaleidoscope 1 episodes Nov 10, 2026

The Builders is a interview series hosted by bestselling biographer Walter Isaacson, who speaks with the most influential figures in AI and technology about the futures they are trying to create. Guests include Elon Musk, Peter Thiel, Alex Karp, Fei-Fei Li, Mustafa Suleyman, and Dario and Daniela Amodei, among others. They discuss their ambitions, their fears, how they think about humanity, and what pushes them to build on such a large scale. The conversations are intimate and engaging, and often unsettling, but hard to ignore. The premise is that we are increasingly living inside the imaginations of these builders, whether or not we agree with them.
