Yes! Thank you, this has been irritating me from day one with agentic AI, I don't think it could be nearly as good as it is without all the well-designed tools humans have spent decades developing from PLs, to VCS, to the Unix philosophy, to CLIs / REPLs.

I think that AI is very skilled and adept at using them, but without them it would just be flailing around in its own psychosis. The tools ground the AI in reality and allow them to make progress without going in hallucinated directions. I very much doubt AI could have solved this problem without Lean, and for AI to invent something like Lean it would have to use other tools made by humans.

This is also perfect evidence of why Python isn't the end-all-be-all of programming languages just because the AI was trained on vast amounts of Python, and proof that the right language for the job is more viable than ever with the aid of LLMs.

Frankly, the forecasting that programming languages are a dead field has baffled me because it seems like with LLMs, unique programming language semantics are more important than they've ever been.
