Times tech columnist Kevin Roose stopped by The Daily twice this week to chronicle the debut of Bing’s new chatbot — and the creepy things that transpired. Today, we’re bringing you the latest episode of Kevin’s podcast, Hard Fork. Kevin, along with his co-host Casey Newton, expand the discussion about why Microsoft’s A.I. search tool appears more powerful — and more unsettling — than they initially believed. Plus: a conversation about Elon Musk’s quest to be the most popular user on Twitter, and why online ads have gotten so much worse (like, much worse). Hard Fork is a podcast about the future of technology that’s already here. You can search for Hard Fork wherever you get your podcasts. Visit nytimes.com/hardfork for more.
