That’s not actually the abstract; it’s a piece from the discussion that someone pasted nicely with the first page in order to name and shame the authors. I looked at it in depth when I saw this circulate a little while ago.
Ah, that makes more sense. I looked up the original abstract and indeed it looks more like what you’d expect (hard to comprehend for someone that’s not in the field).
Though to clarify (for others reading this) they still did use generative AI to (help?) write the paper, which is only part of why it was withdrawn.
