Hey #ALIFE2025 people! Have you heard of Assembly Theory? A month ago, I wrote a good, objective essay summarizing AT's contributions, limitations, and possible improvements. It's perfect if you don't want to read all the critiques and counter-critiques that have been written!

As a promising avenue for unifying physics and biology, assembly theory (AT) has been subject of controversy, being both praised and refuted at the same time.

What is its current status? Has it really quantified selection and evolution?/1

Demystifying Assembly Theory

“It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are who made the guess, or what his name is … If it disagrees with experiment, it’s wrong. That’s all there...

Tech is depleting not only material resources but also intellectual resources, especially common knowledge. Political polarization erodes agreement on the most basic facts and concepts. "It's almost like seeing the ozone layer deplete before our eyes," said @audreyt.org at #ALIFE2025. ⚙️🧫

Evolution has an arrow of time toward greater complexity. It's driven neither by mutation nor by crossover/sex but by symbiogenesis, argued @blaiseaguera.bsky.social (following Lynn Margulis) at #ALIFE2025. He showed lots of cool CoreWar-like competing programs. whatisintelligence.antikythera.org ⚙️🧫

I guess it’s easier to imagine an ensemble of civilizations, for which we can plausibly imagine a selection effect, than of superpower histories on Earth.

At the industry session, He Wang (Galbot Robotics) introduced us to a Vision-Language-Action loop to achieve generalist robots. As a solution to the big amount of data needed to train their robots, they propose the use of large scale synthetic data.

The usual explanation for great music is that it's predictable but not too predictable. But there's more to it, said @frosas.bsky.social at #ALIFE2025. We prefer music when we perceive agency behind it. Improvisation trumps a prepared performance. See paper at www.frontiersin.org/journals/psy.... ⚙️🧫

For A.I. to feel empathy, it has to be able to feel pain, argued roboticist Minoru Asada in a provocative talk at #ALIFE2025. He has built a pain signal into his robots. I hope it doesn’t inure them to others’ misery, as we see all too often in people. www.er.ams.eng.osaka-u.ac.jp/asadalab/?pa... ⚙️🧫

Thousands of NASA employees to bid farewell to the NASA they knew

Yes, NASA science is being destroyed, and the NASA we know is actively in the process of being gutted.

Here are the receipts.

As October begins, thousands of longtime NASA employees are leaving the agency. 4000+ will exit by January 9, 2026, changing NASA forever.

Interesting interview of Eliezer Yudkowsky by @kevinroose.com and @caseynewton.bsky.social. One problem I have with A.I. doomsters is that they equate intelligence with power. When I look around at who exerts power and accrues wealth, I see a fairly weak correlation between those two attributes.

Are we heading for a world in which superhuman AI mathematicians define questions, construct proofs, check them, and then write+peer review the paper about them afterwards? Many mathematicians seem to think so, and some are happier about it than others. ⚛️🧪 #HLF2025 physicsworld.com/a/are-we-hea...

The cells of your body follow simple rules and play off one another to form a complete organism. The researcher Alexander Mordvintsev has developed “neural cellular automata,” building blocks that can self-assemble into any form. @georgemusser.com reports: www.quantamagazine.org/self-assembl...

In cellular automata, simple rules create elaborate structures. Now researchers can start with the structures and reverse-engineer the rules.
