Episode description

This is Alex Heath. For my final episode as your Thursday episode guest host, I recently sat down with Bret Taylor, the CEO of AI startup Sierra and the chairman of OpenAI, for a live event in San Francisco hosted by Alix Partners. Bret has worked at Google, Facebook, and Salesforce in high-level, executive roles, and he led Twitter’s board during Elon Musk’s takeover, so very few people have seen the tech industry up close like Bret has. Now, he’s all in on AI. We covered a lot of ground in this conversation, and I hope you find Bret’s perspective as fascinating as I did.
