In the novel Anathem by Neal Stephenson, the internet becomes unusable for humans thousands of years before the events of the book, due to a process called Artificial Inanity.
AI generated content, both good and bad, some riddled with errors, some with only one subtle error hidden among lots of good information, floods the internet. The internet becomes an unnavigable swamp of weaponized nonsense for average humans. The problem is further compounded by the fact that searching and accessing the internet will be noticed by AI agents that will generate still more swamp content in response.
Unfortunately, it seems that this fiction ended up being prophetic. The open internet will fall to entropy, not legislation or one-sided international trade agreements. I think we need more projects like Anna's Archive, where the public uses torrents and distributed infrastructure to save and organize the world's information. Google has abjectly failed in its original mission to organize the world's information and make it universally accessible and useful.
