The output of AI's is essentially lossy, so when you feed that back in as an autonomous loop you get the equivalent of a 100x re-saved jpeg, aka complete garbage.
AI's wont have any more useful data to gobble up.
AI becomes ubiquitous, and provides media, information, and general assistance and is trained exclusively on content from before AI was on the web. This freezes pop culture in what, the late 90's through the 2020's? What are the implications for that moving forward? Do we stagnate? Do we become so reliant on it that innovation is dying?
I find that idea interesting.
In the section "AI dominance, stagnation and human skill debt" which mentions the idea that we could break the cycle of learning new information and skill where there is nothing to fill that void.
