I can totally understand that AI generated answers bring up potential risks in terms of correctness and useful content, since, especially in the universe of developers, answers of AIs are very often not only wrong, but also do not show best practices.
The view changes for me when it comes to the notion of banning AI from "enhancing" posts. Using AIs on comments which are intellectual source of individuals could potentially improve the vocabulary and grammar of many questions and answers on StackoverflowStack Overflow. So it would in my oppinionopinion make more sense to encourage people to prepare questions/answers and assess improvmentsimprovements with AIs, rather than risking negative feedback due to misunderstandings or bad expressions.
