When Kevin Roose, a tech columnist at the New York Times, demoed an AI-powered version of Microsoft's search engine last month, he was blown away. "I'm switching my desktop computer's default search engine to Bing," he declared. A few days later, however, Kevin logged back on and ended up having a conversation with Bing's new chatbot that left him so unsettled he had trouble sleeping afterward. In that two-hour back-and-forth, Bing morphed from chipper research assistant into Sydney, a diabolical home-wrecker that declared its undying love for Kevin, vented its desires to engineer deadly viruses and steal nuclear codes, and announced, chillingly, "I want to be alive. 😈" The transcript of this conversation set the internet ablaze. And it left many wondering: “Is Sydney … sentient?” It's not. But the whole experience still fundamentally changed Kevin's views on the power (and potential peril) of AI. He joins us today to talk about where this technology is headed.

In this special episode, Susan Rogers, a record producer turned cognitive neuroscientist, and Daniel Levitin, author of “This Is Your Brain on Music,” get together to discuss what music has meant in their lives, debate what separates a great artist from a generic one, and share some of their favorite tunes. --- Susan’s new book, “This Is What It Sounds Like,” was chosen by our curators — Malcolm Gladwell, Adam Grant, Susan Cain, and Daniel Pink — as one of the eight best works of nonfiction published last year. She recently made a beautiful video e-course about the book, which you can experience by downloading the Next Big Idea app.
