The deadline for TikTok to sell or to face a ban is fast approaching. We discuss how Supreme Court justices — who opted on Friday to uphold the law — reacted to arguments in the case, whether the Chinese government might allow Elon Musk to buy the app, and why self-proclaimed TikTok refugees are rushing to a different Chinese app, called RedNote. Then, we talk with an A.I. industry insider about what we actually know about how bad artificial intelligence is for the environment. And finally, after Mark Zuckerberg’s recent appearance on Joe Rogan’s podcast, Casey offers Kevin some ideas for how to bring more “masculine energy” to Meta. Guest: Sasha Luccioni, A.I and climate lead at Hugging Face. Additional Reading: Supreme Court Backs Law Requiring TikTok to Be Sold or Banned‘Red Note,’ a Chinese App, Is Dominating Downloads, Thanks to TikTok UsersChina Weighs Sale of TikTok US to Musk as a Possible OptionMatter of Opinion Podcast: How Democrats Drove Silicon Valley Into Trump’s Arms We want to hear from you.
