Additional cases for permanent ban of answers
In addition to completely agreeing with this for all the reasons already stated in the other answers, and also feeling like it should be permanent (also for reasons stated many times elsewhere), I think there is an additional case for making it a permanent ban that I don't see covered elsewhere:
Under the presumption that anybody can just go to a public GPT instance, type their question, and get a similar (if not identical) answer, then allowing those answers to be posted on SE sites essentially means two things:
It means, to some extent, that the question itself lacked research: If it was that easy to get an answer (ask a bot), then the asker probably could have done that. In some SE communities, this is fine, but for communities where lack of research is generally frowned upon, allowing these answers to be posted essentially encourages questions that the community does not generally want.
More importantly, it means that the Q/A pair is, for all intents and purposes, simply a bot's chat log. If I can ask the bot a question, and get an answer, andthen I put that question and answer on an SE site, then all I've really done is duplicate information that already exists on the internet. While certain SE sites definitely have their share of duplicate information (e.g. SO has a lot of questions whose answers can be found in documentation), it's still generally of no value to add additional duplication, especially when that information is just a copy of a Q/A session that can be had with a given GPT bot at any time. Duplicating logs of chats with bots doesn't really add any value to the internet. SE ultimately serves the purpose of getting knowledge out of small groups of peoples' heads and into large groups of peoples' heads, but this just duplicates what's already out there.
Therefore, because encouraging questions that communities don't want is obviously undesirable, and because duplicating logs of chats with bots doesn't really add any value anywhere, I think the ban should be permanent. In addition, of course, to all the other reasons given.
P.S.PS Furthering the above two points: These bots are trained on existing information, and as such they're not really creating new information. They're effectively just search engines that present reorganizations of existing information in the form of readable text. So asking them a question is roughly equivalent to Googling for a question and interpreting the results. In my opinion, bots should be treated with the same attitude thatas search engines are treated. And answers from bots should be treated the same as answers that are just copy+pasted Google results (i.e. valueless plagiarism).
