However what you asked is wether the vibe coded rust will rot the quality of language ; this is a more difficult to answer to, but I don't think that people who are uninterested in the technics are going to go for rust anyway - from the signals I feedback people are actually not really liking it - they find it too difficult for some reason and prefer to blanket with stuff like C# or python.
Can't explain why.
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.
