Ask HN: Should "I asked $AI, and it said" replies be forbidden in HN guidelines?

They already are against the rules here.

(This is a broader restriction than the one you're looking for).

It's important to understand that not all of the rules of HN are on the Guidelines page. We're a common law system; think of the Guidelines as something akin to a constitution. Dan and Tom's moderation comments form the "judicial precedent" of the site; you'll find things in there like "no Internet psychiatric diagnosis" and "not owing $publicfigure anything but owing this community more" and "no nationalist flamewar" and "no hijacking other people's Show HN threads to promote your own thing". None of those are on the Guidelines page either, but they're definitely in the guidelines here.

This is the correct answer. If you're curious about what other sorts of things are disallowed by common law, look at dang and tomhow's comments that say "please don't":

Where does that saying come from? I keep seeing it in a lot of different contexts but it somehow feels off to me in a way I can't really explain.

It's not "off" unless you're simply reading it literally. If you do that, then it's a verbose way of saying "I agree". But the connotations are something like "I agree, strongly, and in particular am implying (possibly just for effect) that there are objectively right and wrong answers to this question and the other answers are wrong." The main difference is the statement that there is an objective answer to what people may be treating as a subjective question.

If it helps, you can think of it as saying more about possible disagreeing opinions than about the specific opinion expressed. "This answer is right, and the people who disagree are 'objectively' wrong."

It took me some time to catch on to this. It can certainly be jarring or obnoxious, though sometimes it can be helpful to say "yo people, you're treating this like a subjective opinion, but there are objective reasons to conclude X."
