On this episode of The Circuit, Emily Chang sits down with Microsoft CEO Satya Nadella to hear how AI is shaking up the competition for search. Nadella argues that this new wave of technology is as big as the web browser or the iPhone. Chang also speaks with OpenAI CEO Sam Altman to discuss his company (which has some help from Microsoft), its ambitions and the latest on ChatGPT. If you have 24 minutes, this is pretty interesting on the current status of AI at Microsoft and OpenAI.
