If LLMs were developed in an ethical way, this would be good news

The Lean Y3 roadmap is building infrastructure to keep performance "visible and actionable." Radar automatically benchmarks every commit and compares it to previous ones to catch regressions and improvements.

Thanks, @irisvanrooij.bsky.social, because now I know that @barbarafantechi.bsky.social exists. I also hate how Terence Tao is hyping AI for math (and I am not a mathematician - just a #LeanLang fan)

going to do some #LeanLang streaming for the first time in a while!
i tried to get claude code to add polymorphism to my formalisation of HM. let's see what it managed to do and where it got stuck. join me as i do some forensic analysis 🕵️
starting at 7:30pm UTC today!

"I think the other thing that's got real potential is moving away from using English as the main language that you communicate with... There are people who have used mathematical language, Lean is the sort of... mathematical language that allows for processing of mathematical proofs. I think there's some real potential in that because what Lean has that English doesn't is precision." Mathematician and broadcaster Hannah Fry shared this when New Scientist asked her about AI approaches that go beyond transformer-based models.
I don't trust Hannah Fry anymore. She seems to have a strong relationship with Google and DeepMind.
But here she is talking to New Scientist about #LeanLang

Yes. And, for me, the most important point is that it is unethical. They are feeeding the monster. Those companies stole date, use data workers, spend lots of energy and water, and want to spend much more.
I got to know Terence Tao because he is (was?) a big fan of #LeanLang.

I am deeply disappointed by Terence Tao's uncritical use of AI.

Terence Tao on how math is changing, #formalverification as the enabler of scaled human-AI collaboration:
"The reason why scaling and AI and broad participation actually is a net win is because we have formal verification."

I kind of stopped sharing #LeanLang news because all of them now seem to be related to AI. Sad.9

Part of PhysLean is about building good APIs around #physics concepts in #LeanLang. To this end, we have made the following GitHub project to track progress in this direction:

Sad, but it seems everybody is using LLMs to code.
Maybe @algebraic.dev can explain the rules on using AI on #LeanLang source code

I don't understand why they use Lean 4 in the title.
It is Lean.
We don't write Python 3 unless we are comparing versions.
