> I'd argue that vibe-coded rust can be better than just "written-rust

I never thought about it this way, but it actually makes sense. It's just like how Rust / Go / Java / C# can sometimes be orders of magnitude faster than C, only because they're more expressive languages. If you have a limited amount of time, it may be possible to write an efficient, optimal and concurrent algorithm in Java, while in C, all you can do is the simplest possible solution. Linked list versus slices (which are much more cache-friendly) is the perfect example here.
