So the "I left $AILab for ethical reasons" grift is starting up: I understand wanting that bag, wanting to be in on a big thing. But if you thought OpenAI or Anthropic were okay a year ago or so, I really am not willing to give you any credit for leaving now.

It's a beautiful piece and I loved every moment of it. However this ordinance does not protect us from Cory's example in the slightest.

City council to require driverless tech to have a driver. The ordinance is framed as protecting immigrant workers, but its effect is to fix them in a deskilled role that exists only by legal decree. It ties their livelihood to a function the technology is designed to make obsolete. What a self own

Please stop telling high school students to cold email university professors. Really, just stop. If you are a high school student looking for research opportunities, search and apply to the myriad of formal training programs that cater specifically to your education level.

I agree with that in normality but disagree given our reality. We do NOT have that luxury. For me it is simple, extended categorical imperative: act such that fascism is never possible again. Each of us is fully responsible.

Communicating science is about whether the public believes experts, and that question is now highly polarized. Staying neutral doesn't keep you out of that contest. It gives up ground in it. 3

Being tenured we can mute BUT Grad students losing funding, immigrant postdocs, and colleagues at defunded institutions can't. Opting out can be read as leaving them to fight alone. 2

Dr. Jan Zimmermann @janzimmermann.bsky.social · 23/09/2026
I would like to point out a perspective that I think is pertinent. Science is political. Research funding, grant terminations, visa rules and health policy are all decided politically. Sharing science while muting politics means ignoring the forces deciding whether that science keeps happening. 1

But also the fading of phenomenology. Kraepelins writing is still more precise and useful than 20 years of dimensionality reduction to some useless axis.

I think this all the time and typically concluded I was just not smart enough but many modern papers do indeed say very little.

Preprint time! This is a cool one. Complex systems, be they neural nets, interacting genes, or power grids, can produce diverse dynamics-- things like point attractors, limit cycles, and chaos. The dynamic landscape you get depends on how elements interact. But those interactions can also change!

No matter how justified, you can’t spend all of your time angry about world events. It’s important to take a step back and focus on the little things around you that will also make you angry.
