I did not read them. I just saw someone (from Caltech) somewhere criticizing Tao's views

#LeanLang is mentioned twice.

But, of course, right now, #LeanLang has been benefitted by the AI wave. Leonardo de Moura was invited to the Trump Science event.

I mean, in the past, when we saw #LeanLang code we would be almost sure it was written by someone who understood the language*, which is not easy. Now anyone can generate Lean gibberish using an LLM.

* This is far from true for other programming languages.

Sad news for #LeanLang

Because of AI?

Will AI become a negative force for Lean?

It always seemed obvious to me in programming: if the person writing the prompt in natural language is not able to read the formal specification (in #LeanLang) and verify that it makes sense, what's the point of having a formal specification?

I imagined a kind of integration between #ElixirLang and #leanLang some years ago and expressed it in some of my podcasts.

José Valim, the creator of Elixir, is taking care of that now.

What mathematical specification connects their treatment of Navier–Stokes / nonlocal PDE structure, and where do the constructions differ?

Verifiable proof correctness is key. But try doing it on practically anything. Especially in security. 🫠 #leanlang seems quite interesting. Without having to have a mathematics PhD 😅
