This week, we tick through the many dramatic headlines surrounding xAI, including the departure of X’s chief executive, Linda Yaccarino; the Grok chatbot spewing antisemitic comments; and the A.I. companion Ani engaging in sexually explicit role-play. Then, we explain why a fight to acquire the start-up Windsurf startled many in Silicon Valley and may reshape the culture in many of the big A.I. labs. And finally, it’s “crypto week.” David Yaffe-Bellany explains how crypto provisions in the bills before Congress and the president could affect even people who don’t hold digital currencies.Also, we officially have merch!
