There’s a lot at stake in the artificial intelligence race, and although it may feel like it’s everywhere, the U.S. AI race is primarily playing out in just a few places — specifically, hubs that offer AI entrepreneurs advantages like capital, talent and more.

Marketplace’s Lily Jamali spoke with Muro about that concentration and what it means for AI development going forward.
