I feel like everyone has some sort of justification for why their pet language is now the best because LLMs can work in it better for a bunch of reasons.

Javascript/Python is the best because there's so much code out there that the LLMs can train on, and LLMs can write lots of tests to make sure everything is correct. There's nothing to compile, so the LLM can iterate quickly.

Rust is the best because the LLM gets great feedback from the compiler because of its strong type system, and it can deal with the borrow checker for you.

Go is the best because it's a simpler language with a decent type system, and the LLM can reason about that well, and will never forget to check an `err` return. The compiler is fast, so the LLM can iterate quickly.

I could write similar praise for C, C++, Java...

At this point I don't think any language is the best "because LLMs". I think there are quite a few languages that LLMs are probably not good at, but you have lots of choices if you want something they are good at.

I have a pet language Inm love because LLMs have shown themselves to be quite lousy at writing it. It makes programming a lot more fun when you have to do it yourself.

I mean, it can still reason about it, but the code it (Claude and Gemini) frequently doesn't compile and it throws edits onto it until it does. When it then compiles this pretty much c# written in a functional HM-typed sexpr language that lacks classes.

AI has been great help in writing the compiler, though. I got stuck in codegen after having written a lexer, parser and type checker, and not only did it make a faster and better code generator than I ever could, it also made the type checker about 5x fater.
