The problem is every coauthor wants to increase submissions, LLMs are great at making something that looks OK at first glance, and people have low(er) expectations for a conference paper. A recipe for disaster.
Extrapolate a bit and there are LLM written papers being peer reviewed by LLMs, but fear it not, even if they are accepted the will not be cited because LLMs are hallucinating citations that better support their arguments! And then there is the poor researcher, just a beginner, writing a draft, simple but honest material getting lost in all this line noise, or worse out, feeding it.
