If anything I think the opposite, the internet is going to be so flooded by AI pigswill that no one, automated or not, is going to be able to deal with it.
The governments of the world might be able to listen to your phone conversations, but I doubt anyone can listen to whispers in a tornado.
It's not about web pages publishing garbage. It's your comments to HN, your emails to your cousins and book club mates, your reviews on Amazon, etc. Unless you send your friends AI pig swill mostly in your FB messenger chats?
Right now a lot of the data collection is done in the hopes that it becomes useful, AI makes it possible to draw conclusions on ALL the data they're collecting on everyone at all times.
I was being a bit naive/non-descript in my first comment but I'm a pretty firm believer they already had some secret sauce that could do the same job of summarising the information they collect into a human useable level
