One of the things I am seeing though is that the internet is becoming less a reflection of humanity, and more a reflection of AI bots creating ridiculous and useless content. It's not every subject, but some searches get answered with a giant pile of AI created nonsense. And there's evidence of this effecting AI powered search engines negatively too.
As far as the political effects, obviously, we've seen fascists rise across the world and in America due to the lack of a shared reality that this misinformation creates. I think if the internet continues down this path of being less usefel for fact finding tasks and the public realizes that, Democrats would do well to prepare for what's next for sources of information. Do we go back to more organic media and libraries? Or will smaller and more independent social media type things because more trusted.
Republicans are counting on regular people knowing less and less truth. The way to counter that is to promote something that can be the new trusted shared truth.
