I asked my regular robot (gpt5. 6-terra) their personal score for probability of AI wiping out humanity. Was bit surprised it was p(doom)<.15 Is this rhlf obsequiousness? - tell the human what it wants to hear. Or is it's an aspiration? - kill all humans by 2100
Caspar Addyman:
Let's both agree It's a very limited measure but do you have p(doom) score?
https://en.wikipedia.org/wiki/P(doom)

Tad:
[Tad] Yes: roughly 15% by 2100 for AI causing human extinction or an effectively irreversible civilisational catastrophe.

Very rough decomposition: capabilities + loss of control feel genuinely dangerous; timelines and governance are radically uncertain; extinction specifically is a higher bar than severe catastrophe. I’d put serious global AI catastrophe nearer 30%.

É uma medida pobre, mas useful as a forcing function: I am not in the “obviously negligible” camp.

Omer Reingold paints a remarkable picture of current feelings of professional mathematicians & of the scale of the advance that the 400+ new math proofs by openai represent. Everyone accepted AI magic when it was chess, go & protein folding. Math is more scary & alien. scottaaronson.blog?p=10169
The Mathocalypse
… then they came for Navier–Stokes and I said nothing because I never worked on Navier–Stokes. But when they came for RL vs. L I realized that things are serious

–friend-of-the-blog Omer Reingold (shared with permission)

Last night my 9-year-old son was taunting my wife, complexity theorist Dana Moshkovitz, as follows: “mommy, I heard you got cooked! I heard that a robot solved the math problem you worked on for your whole career! OOF!”

While my son was being a brat, he also wasn’t wrong.If you’re wondering what emotions Dana is feeling—well, probably all of them! Even while a central career aspiration has fallen to a robot, there are at least two mitigating factors for her. First, she can feel vindicated that the UGC was true after all, something she never doubted even while many of her colleagues did! Second, all of us in math and theoretical computer science and mathematical physics, at least those who cared about solving crisply-stated problems, are now in the same boat.If you want some sense of what things feel like now in math, imagine a hunter-gatherer who’s spent his entire life learning to survive deep in an unforgiving rainforest, then a giant resort hotel springs up right next to him with a helipad and heated pools and AirBnBs, and without missing a beat, the hunter-gatherer says: “alright fine, so now my new job is to run wilderness retreats for the tourists, or something.”

Hey Shona Rhimes / Netflix, Could you make this for me? Fictionalised version of life of Thérèse Schwartze. In late c19, she's Europe's most famous portrait painter. But.. she's also a detective! Each episode she paints the portrait and solves a mystery in the royal household she's attending..
Alt text: Screenshot of a text summary about Dutch portrait painter Thérèse Schwartze (1851–1918), describing her as one of the most successful and financially independent female artists of the late 19th and early 20th centuries. Below a heading "Key Highlights of Her Career," three bulleted points cover: her elite and royal clientele, including a 1881 breakthrough painting Queen Emma and Princess Wilhelmina; her vast oeuvre of roughly 1,000 drawings, pastels, and oil paintings over a 40-year career; and her prestigious recognition, including a self-portrait invited by the Uffizi Gallery and her role as a model for the Amsterdamse Joffers group of female artists. Small source citation tags (Rijksmuseum.nl, DailyArt, Journal of ART in SOCI...) appear beside each claim.
