Over the weekend, X was banned in Brazil. We talk with The New York Times’s Brazil bureau chief, Jack Nicas, about how Brazilians are reacting, whether its owner, Elon Musk, has made a business miscalculation and what this means for free speech around the world. Then, we’re going “founder mode.” We explore why an essay about start-up founders reclaiming their authority went viral and what that tells us about how Silicon Valley thinks about power. And finally, we hear from listeners. Teachers and students left us voice messages describing how phone bans in schools are transforming their lives.

Guest:

• Jack Nicas, Brazil bureau chief for The Times
