If an author doesn’t have time to write. Why should I give up my time to read?

Because -- if the author is to be believed -- essentially no one bothered to look at this work at all before AI became available to help with it. I had certainly never heard of it before. Had you?

That's the choice being offered. Not between "LLM slop" or "painstaking human authorship", but between something being done or nothing at all being done.
