Right, they run tests too. A compiler is like a quick test before tests. How are you going to cut out that check and let the LLM "write it faster" is beyond me. The compiler catches errors across codebases that today's LLM can't economically or reliably put into context to perform similar checks. They're totally different tools, today.

Also, you can just compile less frequently.

But hey, if LLMs are what drove this person from Haskell to Lisp then all the power to them!
