My thoughts on the current state of AI driven software development, why I'm no longer concerned about a runaway intelligence explosion, and what I think is a far worse outcome we could be walking into maevyn.codes/decoherence
Ik vraag me af of dat over een paar weken of maanden nog steeds het geval zal zijn. @nrc.nl www.nrc.nl/nieuws/2026/...

A glistening little illuminated initial from a Latin Bible written in the early 14thC, possibly in Germany. It illustrates the beginning of chapter 11 of Isaiah, where the Holy Spirit (doves) rests upon the branch (the messiah). Bought by @theulspeccoll.bsky.social in 1891 & now MS Add. 3030.
I thought for a moment that this was about how LLMs "experience" reality ☺️
*Well, it's a dumb question if you want it to be a dumb question, but if you want to reframe it as an "umwelt" question of how other species really do experience reality, that's quite a profound question en.wikipedia.org/wiki/Umwelt

Critics of AI engage in the reverse naturalistic fallacy (i.e., the move from ought to is): reasoning from the moral and social ills to the position that the technology itself doesn’t work well. @fennert.bsky.social link.springer.com/article/10.1...

Toen al werd AI uitgelegd en NU nog staan we met onze vingers in onze oren. Ik snap niets van de mensheid. Alsof je in de fik moet staan om te weten dat vuur gevaarlijk is. www.youtube.com/watch?v=RXJK...

We may finally know that for any n, there exist n² unit vectors in ℂⁿ that all lie at the same angle from each other! More precisely, |⟨v,w⟩| is the same for any two different vectors. The proof is crazy hard, and it required a new result in category theory.
You may finally rest easy at night since SICs exist in all dimensions! github.com/marozols/SIC... SICs are d² unit vectors in d complex dimensions with pairwise equal inner products. Their existences in all dimensions d was conjectured by Zauner in 1999. en.wikipedia.org/wiki/SIC-POVM

*Look, science fiction was invented in the 1920s, while libraries have been burning-down ever since Sumeria *However, Artificial Intelligences getting burned down by remotely-targeted robot missiles, that's an exciting new trend *Is this situation some fantasist's "anxiety," no it isn't
It's funny, really: sci-fi literally depicts this stuff - desscrution of digital databases leading to complete loss of knowledge. Then again, that's more a case of just reflecting the anxieties of the present rather than predicting the future. Disturbing to see it play out, though.

Things I learn by talking to people: Inventiones has a very good AI policy. We should have the same policy everywhere, including arXiv. First and foremost "AI cannot be an author". (No, I don't like the word seminal either.) link.springer.com/journal/222/...
"If a human did this, it would be an instant Fields Medal, no questions asked"? 🤷 thezvi.substack.com/p/new-math-f...
And that answer is... it depends! 😁
Talk and panel done!!! I think I did good and held my own after falling off for 4 years. Slides are uploaded. Not sure if they will provide the talk or anything publicly, I forgot to hit record on my end because some technical issues derailed me, haha. thephd.dev/_presentatio...

Om welke bedreiging moeten we samendrommen op het Museumplein? ☺️
De eindtijdverkondigingen met AI in de hoofdrol vliegen ons om de oren. In mijn nieuwe column voor @dekanttekening.bsky.social schrijf ik over AI en de dreigingen ervan. Hoe uniek en reëel zijn die dreigingen? Te lezen via onderstaande link. dekanttekening.nl/columns/uits...

"I spent a lot of time going over the design decisions involved here, trying my best to complain about async Rust, only to end up going “Oh. Yeah. That’s reasonable. That makes sense. I can see why they did it that way.” every step of the way." herecomesthemoon.net/2026/10/asyn...

I've started my new job! As of today, I'm a postdoc in the Software Science group of the Institute of Computing and Information Sciences at Radboud University in the Netherlands. This position is (largely) funded by a personal 3-year Veni fellowship from the Dutch research organization NWO. I'm […]
