The more direct problem for people in general is that finding what you're looking for has become even more of a "needle in a haystack" problem than it already was.

The indirect problem is that if genuine content creators can't get much out making content (not necessarilly money: for many simply the satisfaction of seeing how many people liked their content is incentive enough) because viewers are much more dispersed due to the AI-rewritten info cloning sites, then there won't be much new info for the cloners to copy in rewritten form, which is maybe fine for "questions already answered 1000 times" but won't be for questions or tutorials about new stuff.
