This week, President Trump announced sweeping new tariffs that are roiling the global economy. We discuss what this could mean for the tech sector and whether this will give China a competitive advantage over the United States in the development of A.I. Then, we chat with a Wall Street Journal reporter, Keach Hagey, about her new book on Sam Altman and how she solved the mystery of his firing from OpenAI. And finally, Tinder has a new chatbot that you can practice your flirting skills with — which means it’s time for a flirting competition.

Guest:

• Keach Hagey, Wall Street Journal reporter and author of the forthcoming book The Optimist: Sam Altman, OpenAI, and the Race to Invent the Future.

Additional Reading:

• What Trump’s Sweeping Tariffs Mean for the Global Economy, and for You

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”
