This week, we dig into the group chat that’s rocking the Trump administration and talk about why turning to Signal to plan military operations probably isn’t a great idea. Then, we’re joined by the podcaster Dwarkesh Patel to discuss his new book “The Scaling Era,” and whether he’s still optimistic about the broad benefits of A.I. And finally, a couple weeks ago we asked whether A.I. was making you dumber. Now we hear your takes. Guest:Dwarkesh Patel, tech podcaster and author of “The Scaling Era: An Oral History of A.I., 2019-2025” Additional Reading:The Trump Administration Accidentally Texted Me Its War PlansSignal Chat Leak Angers U.S. Military PilotsIs A.I.
