I am a small person in the forum staff. All I can say is that such a question has not yet been raised among the forum staff. As for me, I have already voiced my opinion on this matter. I will repeat here that until there is a sufficiently valid algorithm for identifying such texts, I think that nothing will change in the rules of the forum. If we introduce such a rule now, it would create chaos.  Many users, who will be caught using AI and whose posts will be deleted, will start to create topics in the Meta with complaints about the wrongful actions of moderators. Today moderators do not have tools for checking, which would fully confirm that one or another user used AI in his posts.
