> Has basic reading become a Herculean task?

I find LLM slop much harder to read than normal human text.

I can't really explain it, it's just a feeling.

The feeling that it draaaags and draaaaaags and keeeeeps going on and on and on before getting to the point, and by the time I'm done with all the "fluff", I don't care what is the text about anymore, I just want to lay down and rest.

Same here. The text is pretty smooth and there is nothing that stands out to sustain my attention, at least that's my interpretation
