I'm no longer in academia but I was asked to review a paper recently which was similar to one of my final papers, so I accepted. The paper was written by four Chinese authors who had previously collaborated together. It was one of the worst papers I've ever seen. It went over the same ground as previous studies so in that sense there was nothing new, but more bizarrely it did things like state well known equations incorrectly (most notably one of Maxwell's equations) incorrectly and drifted off onto total tangents about how one might calculate certain things in an idealised situation that had no relevance to the method that the authors used. My assumption is that they had generated the methods section using generative AI and not gone over it with even a cursory check. But the worst part is that I recommended rejecting it outright, and the journal just sent it on to it's slightly less prestigious sister journal rather than doing so.
