OpenAI acquires TBPN. OpenAI bought John Coogan and Jordi Hays’ daily 3-hour tech show TBPN, with new “CEO of AGI Deployment” Fidji Simo framing it as a bet on “constructive conversation about the changes AI creates.” Editorial independence is promised — but Silicon Valley owning its own media pipeline is the real story, and the labs are no longer pretending to be neutral.
