In one week, two open letters laid bare the deepening fracture in Silicon Valley over AI. Nvidia CEO Jensen Huang posted a letter opposing "premature restrictions on open weight models," signed by Microsoft, Meta, Mistral, Hugging Face, and later by OpenAI and Google — but not by Anthropic. Days later, a separate letter called "Pacing the Frontier" appeared, signed by more than 1,200 employees of frontier AI labs, including Anthropic CEO Dario Amodei. Its core request: that the U.S. government develop the technical and governance tools needed to deliberately slow automated AI development.

Show Notes

This week, we break down the arguments about open-weight models unfolding in Silicon Valley right now. Nvidia released an open letter signed by over 230 companies opposing “premature restrictions,” but will the Trump administration listen?

Then, we’re joined by the author Claire Stapleton to discuss her new book about what she learned while leading employee activism inside Google.

And finally, can Substack stop the slop? We’ll talk about the platform’s new A.I. detector.

Guests:

  • Claire Stapleton, author of “Don’t Be Evil: Bad Bosses, Fake Promises, and My Escape from Big Tech.”
