Tech Feuds and Environmental Ironies

OpenAI spent the week responding to outcry from users who miss the behavior of the old ChatGPT, before the latest flagship model was released.

We discuss the criticism, why it caught the company by surprise and what it indicates about the deepening emotional relationships that people are forming with chatbots.

Then, Aravind Srinivas, the chief executive of Perplexity AI, joins us to discuss his company’s new artificial intelligence-powered browser, Comet; his company’s bid to buy Google Chrome; and what the future of the internet looks like when users turn to A.I. assistants to browse the web for them. Finally, to cap it all off, we rate the craziest tech stories of the week in our game Hot Mess Express.
