In this special episode, in partnership with Frontiers Science House, we launch our new Why? series by asking one of the biggest questions of our time: Why AI? Why has artificial intelligence advanced so rapidly, why does it work the way it does, and why could it fundamentally change how we think, work, and live? To explore the answers, we hear from four remarkable voices at the heart of the AI conversation: Geoffrey Hinton, Mike Wooldridge, Cristina Criddle, and Wendy Hall. Like this podcast?
