What if there was a source of energy that was virtually inexhaustible, produced no greenhouse gasses, and generated minimal waste? Well, it already exists – almost. Reid and Aria sit down with Dr. Kim Budil, director of the Lawrence Livermore National Laboratory, to talk about the future of fusion energy. Last December, Dr. Budil’s lab achieved fusion ignition. She explains what that historic breakthrough means, and what levers need to be pulled to go from that experiment to powering nations. Dr. Budil responds to stories, generated by GPT-4, about scaling fusion energy, plus another about how a country can transition to fusion energy in 2053.  Read the AI-generated stories for this episode here.

Most of all, it asks: what if, in the future, everything breaks humanity's way? Hosted by Reid Hoffman and Aria Finger, each episode features an interview with a visionary from a different field: climate science, media, criminal justice, and more. The conversation also features another kind of guest: GPT-4, OpenAI’s latest and most powerful language model to date. Each episode has a companion story, generated by GPT-4, which will serve as a jumping-off point for a hopeful, speculative discussion about what humanity could possibly get right if we leverage technology—and our collective effort—effectively.
