I think you missed the point. Yes it was meant to be humorous, and also to emphasise one of the reasons AI-generated citations are completely untrustworthy, especially with the growing number of AI-generated (junk) papers being published.

No, I had no intention of trying to offer a real source for the accuracy of AI generated citations. It is not hard to Google, search HN or even (ironically) use AI to search, to find numerous relatively recent studies discussing the problem or highlighting specific cases of respected journals/conferences publishing papers with junk citations.
