In my opinion it won't make any difference, cause I've seen some AI's popping up that detect if a piece has been written by an AI or not, just like plagiarism checker, but I can't say about their performance. Till those become mainstream, I believe you're right.

I know people who write for these sites, most of them know nothing about the topics they've to write about so they just google stuff for 5 mins and write like 500 words to get paid. Most of them are freelancers so they can't afford to invest in the topic. Hence, end making a vicious cycle of underpaid writers and Jack ass content.
