A great read. I have similar feelings about how AI labs approach progress directly and without nurturing of scientific communities & intuition. The math research community went through the transition the fastest, so it was felt most. Other fields next. terrytao.wordpress.com/2026/09/11/a...

Can A.I. “Go Rogue”?
In the wake of turmoil at OpenAI and Anthropic, it’s become common to describe A.I. as a kind of person, hatching plans and pursuing desires. The truth is a little trickier.

Anyone else getting lots of (AI-written) emails offering to feature one's book at their large online book club? I've gotten several of these in the last week. There's something scammy going on but I'm not sure what the angle is.

What, an Anthropic researcher states (without evidence) that there is a 10% chance that AI will cause human extinction? Incredible, we have never before heard such a claim!

Hey @ericlipton.nytimes.com 👋 AI is not “evolving” on its own. *People* are choosing how to build it. *People* are choosing how to train it. *People* are choosing how to run it. Maybe the problem is that they are the *wrong people* to make these choices.

"At this very moment, we have an emerging alien—and uncontrollable—intelligence that bears scrutiny" Why do pple keep saying the models are "uncontrollable"? Any of them could be put in an unhackable sandbox--these exist! Any of these companies could shut any of these models off at any time.

Thanks, but actually my favorite line didn't make it to the piece. Does Odysseus feel guilty about the Trojan war? Lots of discourse on this question even though he doesn't exist! Is he conscious? AI agents are fictive characters abstracted from text - like Odysseus.
