My calculus is very simple these days:

If I care about performance, use Rust.

If I care about iteration speed, use TypeScript.

If I want a script or numerical code, use Python.

LLMs are better with Rust because the more expressive type system provides stronger guardrails especially when writing multithreaded code. Go is almost the worst conceivable design of a programming language for LLMs: powerful but weak guardrails. Only C and C++ would be worse.

LLMs don't struggle with the low-level lifetimes like humans do. They struggle with the high-level view because of limited context windows. That's why you want a powerful type system to enforce those global constraints. Go ain't it.
