Nov 2025 LEAP panel of AI experts and superforecasters: 10% chance of AI helping solve a Millennium problem by 2027. "One expert cites the Clay president's June 2025 claim: “We're very far away from AI being able to say anything serious about any of those problems” (Heaven 2025)"

A few things on Navier-Stokes. 1) An unreal achievement, 2) $15 million dollars of output (300,000m tokens at $50/m)!, 3) they explicitly claim they never looked at user data from the NYU/Anthropic team, 4) I would release literally everything given the gravity of the accusation. 3K views · 51 likes · 0 reposts · 3 replies Open on X →

Just to be clear: stupid rumor based on insinuation in the Navier-Stokes letter that OAI folks may have "read the chat transcripts to get the idea" makes no sense to anyone who knows how these models work or how the data contracts work. As Sholto says, please stop repeating this. 25.1K views · 185 likes · 9 reposts · 15 replies Open on X →

US and Canada hold up quite well in PISA 2025...but only relative to global collapse due to COVID/phones still not recovered, esp. for reading scores which just continue to plummet (some of which are now shocking even in well-off countries). 4.8K views · 20 likes · 0 reposts · 2 replies Open on X →

I love this bet. Not a gambling man myself, but just to be clear, 99.9% of economists would take the no-fast-growth side if forced. 15% annual growth by 2033 would require implausible diffusion speed. Think about Waymo diffusion given their tech, and apply broadly... 26.7K views · 109 likes · 9 reposts · 3 replies Open on X →

(And one follow-up from DMs - def a case for the top 20 or so. But a *lot* of good-but-not-really-transformative folks, mid-career, at random institutions, hired with $8m research budgets (5x the next highest standard Canada grant), which does not seem like good value for money) 2.3K views · 5 likes · 0 reposts · 0 replies Open on X →

(Btw, the most surprising thing is that there are zero computer science or robotics hires, with perhaps the exception TBW, who applies AI to ecological conservation.

Still seems to be a successful program with a few very very big names, but not really at the "recruit 64 world-class folks" given the $ involved, and still with the historic pattern that top hires away from the US tend to be citizens of the hiring country. 4/4 5.3K views · 16 likes · 0 reposts · 2 replies Open on X →

Canada announced the 64 chairs of their huge intl recruitment drive. Some major stars (we are bringing Ray Fisman to Rotman) so I was curious about what the nature of the hires way. 1/4 41.7K views · 93 likes · 8 reposts · 5 replies Open on X →

Of those 21, 4 came from outside the US. Of the remaining 17, 9 are Canadian. Still some great hires, e.g., Sara Seager, but maybe less surprising. The remaining 8: some combination of declining US funding in the area + many-millions lab packages. 3/4 5.6K views · 11 likes · 0 reposts · 1 replies Open on X →

Kevin A. Bryan@Afinetheorem27 Aug

From a little work with AI and Google Scholar, I'd put 21 of 64 in the "these would be a better than average, clearly, hire for a top Canadian university". I suppose that's a bit disappointing given the huge amount of money devoted, but it was a quick program. 2/4 6.5K views · 15 likes · 0 reposts · 2 replies Open on X →
