At some point, it will be expected that people creating content (writing/video/etc.) use a human validation service to prove that they aren’t AI. Anyone that doesn’t use this (and presumably uses AI) will be deranked from YouTube and social media.
And their human content fed into the machine, so it can be mass produced whenever and wherever desired, allowing less of the total benefit to flow to the creator, giving them just enough incentive to keep feeding the machine.
Content ecosystems are only valuable as ecosystems. If everything on a platform becomes AI generated, the average person will stop caring - and they’ll switch to a social network that enforces humans-only.
I don’t think it’s a realistic understanding of psychology or sociology to think that people will be happy only consuming AI stuff.
