For AI you definitely need to clean up and I think even targeted learning on some practices would be beneficiary ; for users ; it depends on the people, and I'd argue that vibe-coded rust can be better than just "written-rust" IF the important details and mind of the user are actually focused on what is important ; Eg ; I could vibe-code a lock-free well architect-ed s3 - focus on all the important details that would actually make it high perf - or write some stuff myself 10x slower - which means I will have 10 x less time to work on the important stuff.

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.
