alt Hacker News> Please consider not vibe coding rust as AIs are not good at writing Rust and also hire a real rust dev
Isn't the whole point of AI companies using Rust that it's explicit, safe, and AIs are fairly good at writing it?

I suspect "Rust is fast/low memory utilization" is the more common value proposition, with memory safety as the bonus that can push it over other fast languages.

AI is not good at writing Rust. The ways in which it is bad vary from writing code that just looks off to actually not working. I do not use unsafe frequently so cannot comment on this particular scenario but I have seen similar stuff often, most Rust code that I read from AIs has at least one or two issues.
In particular, if you have a situation that requires any kind of conceptual understanding then AI will likely have issues. Sync blocking async is the classic example. My theory is that humans make this worse because they will often prompt in a certain direction and AI will faithfully build the footgun.
