The issues they bring up about AI slop are real (e.g. how to deal with easy to generate but hard to verify submissions).

Have you seen an increase in AI slop in articles you had to review, in your field?

As a referee, it's not too bad for now in my field, the underlying science is still usually sound, even though I get annoyed at times, yet relieved that I don't have to read broken English anymore.

For editors, I heard, it's getting bad, and they can barely find referees anymore. But the system was already breaking before AI, AI is just accelerating it.
