I can sorta understand that, but both a thesaurus and an LLM when used as tools to enhance and extend your own knowledge and skill can totally be a good thing. The problem is that many try to use such things as a substitute / replacement for their own knowledge and skill, to do the actual human creative work part for them. That's where the real fault lies; Not in the tools themselves, but in the user mis-using the tools.
Also, not sure why the prior comment was gettin' down-voted. I'm just tryin' to be encouraging here. If this guy has an idea and wants to write, I'm just sayin' "go ahead and do it then". Why not? Even if nobody ever reads it, if you enjoy writing it, then something was gained.
