The Mirage of Autonomous AI Scientists
Science as AI’s killer application cannot succeed without scientist-AI interaction: Introducing Hypogenic.ai.
cichicago.substack.com
AI can accelerate scientific discovery, but only if we get the scientist–AI interaction right.
The dream of “autonomous AI scientists” is tempting:
machines that generate hypotheses, run experiments, and write papers. But science isn’t just automation.

We're launching a weekly competition where the community decides which research ideas get implemented. Every week, we'll take the top 3 ideas from IdeaHub, run experiments with AI agents, and share everything: code, successes, and failures.
It's completely free and we'll try out ideas for you!

If you're a student in need of a personal website (and if you're doing research, yes, you need a website!), I keep a list of nice examples here, most of which are reusable: www.are.na/maria-antoni...
For example, I just spotted this beautiful website by Catherine Yeh: github.com/catherinesye...

❓ Does an LLM know thyself? 🪞
Humans pass the mirror test at ~18 months 👶
But what about LLMs? Can they recognize their own writing—or even admit authorship at all?
In our new paper, we put 10 state-of-the-art models to the test. Read on 👇

Yes, more companies should move to Chicago!
Chicago is a city, a far better (and bigger) one than Seattle? It's not a purge if you move your company somewhere you can afford? I'm not suggesting living in a woods. There are lots of communities with great hipster restaurants & entertainment even in the rustbelt, you just have to look a little.

AI can write complex code but fails at 4-digit multiplication. 🤔 New research by @elenal3ai.bsky.social & @chenhaotan.bsky.social reveals why billions of parameters can't solve grade-school math—and what it takes to fix it. It's about how AI learns, not how much it learns.

Every clause in this (on AI science) !!! 👇👇
It’s also a resource allocation problem: deciding what matters, which hypotheses to test, and which results to trust.
Automation can produce knowledge, but meaning comes from human judgment.

What is the best way to find faculty job advertisements for CS/info students on the job market? It seems that students in my group are spending an unreasonable amount on this. I thought CRA is good, but seems not active any more.

This resonates very well. I think it should apply to all disciplines. I also really liked this recent piece by Channing and Ghosh: arxiv.org/abs/2509.06580

Jilian Fisher gave a thought provoking talk on political bias. 1. Biased LLMs influence people’s political decision making. 2. We should seek approximations of political neutrality given the impossibilities of a perfect definition.
