Anecdotally I think AI is quite good at langs with lots of training data: C#, TypeScript Rust.

I also think it's much better with languages with more guardrails and clear syntax: think expressive types (sum types), brackets, and linters / compile checks.

Rust has expressive types and lots of compile checks to avoid classes of bugs via ownership / lifetimes and I think makes it a very good tool for agents to use.

I partially agree, but C++ is the second best agentic language! (of 6 tested). LLMs are pretty good at reading machine output. My pet theory is that it has more to do with the training data in lower level languages being of a more interesting algorithmic variety, on average.
