What I mean by "the end of information" is that junk information will start to pile up. Misinformation, just plain wrong ideas, pseudoscience and so forth will start to creep in everywhere.
You ever made a xerox of a xerox? That's what will happen as AI starts to put information onto the internet, which will then feed back into other AIs who will put the altered info back out.
A decade from now you won't even know who the president is. Hell, you won't even know if 1 = 1 or if it equals 2. Bridges will collapse as they're designed by AI which was fed by another AI which was fed by another, etc. Each layer of AI will magnify small mistakes made by the previous one. The world will essentially become perpetually deadlocked as everybody tries to figure out what is real and what isn't.
Imagine this over generations, toddlers shown AI generated images of tree dwelling sharks, or public figures being arrested, etc. Information will no longer exist.
