Today we’re bringing you an episode from the recently launched New York Times podcast, Hard Fork. Hosted by veteran tech journalists Kevin Roose and Casey Newton, Hard Fork is a rigorous and fun exploration of Silicon Valley’s already-emerging future — and its evolving imprint on the rest of the world.

In this episode, Kevin and Casey discuss Elon Musk’s on-again-off-again – and recently on-again – interest in Twitter, as the billionaire signals once again that he’s buying the social media platform. What might be behind the change of heart? And what will the deal mean for employees and users? Casey and Kevin swap theories and predictions — and also step into the metaverse with the New York Times reporter Kashmir Hill.

Hard Fork is produced by Davis Land. Edited by Paula Szuchman and Hanna Ingber. Fact-checking by Caitlin Love. Original music by Dan Powell, Elisheba Ittoop and Marion Lozano. Engineered by Corey Schreppel. Special thanks to Sam Dolnick, Shannon Busta, Julia Simon, Larissa Anderson, Pui-Wing Tam, Kate LoPresti, Nell Gallogly, Mahima Chablani and Jeffrey Miranda.
