Relative to Go? I'm pretty sure your Go code won't be faster if you used LLMs. If you need that, Rust is still preferred.

Relative to C/C++? That'll be very interesting. Do you have some evidence that LLMs can create memory-safe code in C/C++? It'll be truly amazing if true, but given that they apparently struggle to create/maintain big codebases in already-memory-safe languages I seriously doubt it.
