In cellular automata, simple rules create elaborate structures. Now researchers are working backward — starting with the result to learn the rules behind it. @georgemusser.com, SFI’s 2025 Journalism Fellow, explores how this could reshape computation and self-organization in Quanta:
Self-Assembly Gets Automated in Reverse of ‘Game of Life’ | Quanta Magazine
In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules.

Good news, everyone!
I researched every attempt to stop fascism in history. The success rate is 0%.
Once they win elections, it's already too late.

New paper: "Large Language Models and Emergence: A Complex Systems Perspective" (D. Krakauer, J. Krakauer, M. Mitchell).
We look at claims of "emergent capabilities" & "emergent intelligence" in LLMs from the perspective of what emergence means in complexity science.

At a time where the vulnerability of relying on US digital infrastructure and cloud services is *huge*, our @algosoc.org research program pilot to rely on *European* cloud services is more relevant than ever. [edited]

Recently I've given a number of public talks on how information tech, including social media, is impacting our ability to make collective societal decisions.
But it was this Q&A session with Rob Brooks at @unsw.bsky.social that I think best captured the story I'm trying to tell. Full podcast here:
