Episode notes

56% of the population today lives in cities. That's going to be 70% globally by 2050. We need to do whatever we can to make them better, safer and more affordable. I think when our streets emptied out of cars, people suddenly saw what was possible. It really showed that you could change your streets. They didn't have to be designed for cars all the time.

What if we didn’t need cars? Janette Sadik-Khan, former Commissioner of the New York City Department of Transportation, helped revolutionize some of New York’s most famous streets into navigable, car-free areas. She joins the show this week to paint a picture of cities that put people first. How has the purpose of the city changed over time? Is it really possible—and preferable—to remove cars from cities altogether? And what does the future of cities really look like? Janette also responds to speculation about the future of transportation via GPT-4’s stories of how people might traverse Istanbul and Vietnam decades from now. It turns out, we might need a lot less new technology than we think to create the people-first cities of the future.

Possible is a new podcast that sketches out the brightest version of the future—and what it will take to get there. 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.
