Not as much of a lack of seriousness as excusing away hallucinations as not that big of a deal in what's supposed to be a researched, scholarly body of work written by humans.
In 2026, LLMs are highly intelligent. In many ways, they even surpass human intelligence and ability. Dismissing them as "bullshit generators" is utterly unserious, and shows that one does not want to deal with the reality of the situation.
I don't see anyone excusing hallucinated citations. I see people arguing that this is an overreaction by the arXiv. AI is going to become a major part of research, including in writing papers. It would be better if people would freak out a little less about that fact.
If the author just wanted to add a citation to some canonical paper (like "Attention is all you need") at the last minute, used LLM autocomplete to do it, and didn't carefully check that the citation was correct, then a year-long ban is a massive overreaction. A careless miscitation is not on the same level as something like data manipulation.
In general, I think everyone needs to be practical about what the actual risks are of LLM use. Are we worried about true nonsense flooding the arXiv? Or are we worried about tracking authorship when LLMs are involved? What's the actual concern?
