i think the mass extinction of the dinosaurs is the highest recorded ratio of birds killed with one stone.

There are orher things than problem solving: What about the invention of new concepts, the general understanding and the explanation?

Fabulous! @svalver
Flysch cliffs, Zumaia, one of most amazing geological formations I've seen. These vertical layers run for 8 kilometres along Basque coast, each a page+forming a book covering 60 million years of planet's history. Created when Iberia crashed into Europe and things went all squishy

The Society for Mathematical Biology (SMB) is soliciting applications for Editor in Chief of its flagship journal, Bulletin of Math Bio. It's an important role, in a pivotal time in history for math bio!

Interesting angle indeed! Seen from this perspective, it's easier to grasp that the Baltic Sea was connected to the White Sea during the early Last Interglacial #LIG ~127,000 years ago [~133-124 ka], with the rest of Fennoscandia effectively becoming an island for ~9,000 years.
The Baltic Sea from a different angle. Perspective matters. This looks vastly different and more involved than a standard map of Europe. Source: buff.ly/PvqiVck

As see this pattern as cleverness vs intelligence dominance inside the fields. As the AI destroyed problem-solving bottleneck, my conjecture would be that math will change the disruptiveness curve to resemble biology, where synthesis is more important. CC: @svalver @PalaeoPhilo

Life finds a way...
Young people actively hate AI. My two younger daughters are 19 and 18, both at universities - one in the UK the other in Italy. Through them, I happen to know quite a few kids their age. And ALL OF THEM seem to universally hate AI. To them it's "something old people invented that we now have to deal with... as if climate change wasnt enough" AI is cringe. When they introduce me to their friends, they literally say "heyya, meet my dad, he's a software engineer but nonono, NOT IN AI, dont worry, hahah". They hate it for flooding their social feeds with slop, ruining music, taking phone scams to the next level, also destroying careers & devaluing their hobbies - why become an architect, this skill is about to become worthless? Why learn a musical instrument if session musicians are already obsolete? The outcome is interesting, though - they're spending less and less time on public social, meeting up IRL, moving their online lives into private group chats with actual verified friends. TikTok and Reels are increasingly cringe-something for old dudes. Which, I guess, might be a net positive after all...

If it was a real science endeavor from which we can generalize to full extent, the Open AI should have reported all the details of their inference procedure, including the patterns of failure. Which problems are yielding and why? Which are not and why? #Explanatory_science
"when OpenAI published their..October 6, 2026, Drop..they mentioned having tried 4000 problems, reporting success for some hundred.. seems to imply the existence of a potentially large group of problems on which the frontier LLM failed to find solutions" terrytao.wordpress.com/2026/…

Oh, this will start a war of values and the faith in science
If we want to continue progress in science, we must be prepared to acknowledge that the correct description of nature will eventually simply be too complicated for humans to understand. I do not think it is wise to make human understanding a requirement. AI is the way forward.

Absolutely true. Go and search for opportunities. Show yourself. People are too busy on themselves to care and take interest in you.
This reminds me of my own post-PhD experience. It was after the 2008 crash, and research oriented industry jobs in the US were scarce. I applied to triple-digit jobs online and didn't get a single interview call. By the standards prevalent at the time, I had an extremely good CV with all the right credentials. But I made two big mistakes. First, of graduating in a tough job market, of which I couldn't do anything about. Two, not reaching out to potential employers via my network. Part of it was pride. But a large part was also driven by my extremely high opinion of my own capabilities -- I thought that if someone wanted me, they should come to me (the former is still very true, btw). Eventually, I realized my mistake, and reached out to my network and I ended up getting 5-6 interviews. Those translated to 3 offers, one of which I eventually ended up taking. The whole experience taught me two very important lessons: 1. Network effects matter, irrespective of how good your CV is. 2. If you want something you need to go to people; they won't come to you, irrespective of your capabilities.

Intelligence is non-homogenous thing. From the point of view of the visual memory and inference Clark’s nutcracker (Nucifraga columbiana), who remembers where he stores tens of 1000s of nuts in dynamically changing forest, can think about humans as primitive, mediocre creatures.
Mathematician Terence Tao: "one thing this whole era of AI is teaching us is that our idea of intelligence is not really accurate" The history of AI has been: 'here’s a task only humans can do', and then one by one, an algorithm does it too Maybe we're not quite as smart as we think

The craziest thing in this story is that it became standard to call 30 year old middle aged men "juniors".
the "junior hiring isn't cooked" crowd is currently undergoing an overdose of copium
