The issue is the blind trust that the internet is built on top of.
It's was that initial good faith that made the internet a special thing - you could come online and discover all the weird interesting things people were up to, have conversations with real people that weren't possible in the real world.
At this point most platforms have figured out how to exploit and profit off the blind trust - but AI is threatening to annihilate it completely.
I'm not worried about the generic content, the worthwhile stuff is what's at risk.
