arXiV is not intended to be your blog. You should be held to a zero-mistake standard when publishing academic work.
The people I worry for are the junior researchers who are going to be splash damage for dishonest PIs. The PIs, though, deserve everything that’s coming for them.
Maybe I'm misunderstanding you, but zero-mistake seems harsh. I would say that AI references are a sign of something that is not simply a mistake.
However, we can have zero tolerance for certain techniques for "writing" a paper. Plagiarism and inventing data are already examples of this, if there is evidence for these techniques being used there is no excuse. We could say the same for AI references - any writing process that could produce these is by definition not a technique we want.
So the mistake isn't not checking a reference the AI gave. The mistake is letting the AI make references for you.
If we agree that academic research is important then I think we can impose certain standards on how you do it. We can dissalow certain tools if that means we can't trust the output. Just like an electrician can't use certain techniques, even if they're easy, because we don't trust the final result.
