Well, yeah, 99% of arXiv papers were not written for me or you. They were written for someone who works in a niche within a niche. That's (in my view) the beauty of research.

Agreed. There was already too much human generated slop in academia.

And I’m not talking about good faith research that didn’t pan out, I mean research that is completely useless for any other purpose other than convincing a casual observer that the authors are doing research.
