One of them is its potential for bringing on a condition where people no longer trust any sources of information
Oh but wouldn't that be great? People would have to start trusting their own observations and experiments, and direct interaction with other human beings, and build trust on them on individual level (by learning to know them). That would be a huge advance in society.
Contamination of "trusted" sources unfortunately happened well before AI. There has never been such a thing as a generic source you can trust. Some people believe what is said on TV, or newspapers from large mainstream media outlets, but these were
always compromised, these
always had a political, religious or some other kind of an agenda. (During different times, the agenda of course changes.)
I think you have a valid point - you are right. I don't like the fact we have to trust and accept without any questioning "official" information fed to us, and lately who feeds that information has become more fluffy; in totalitarian systems, it's the government and a few selected media outlets controlled by said government, but in modern times it's a weird and untraceable mix of megacorporations and AI systems hallucinating something up and now you are supposed to trust all this.
I trust in people - people hate this already and will get fed up with it. As a result, and I quote you because it was so well said: they no longer trust any sources of information.
And that's a great thing. That's exactly what we should do: stop trusting sources because they feel trustworthy. Instead, evaluate what is being said, and compare with your own experiences, observations - does this make sense? Use incoming data, no matter of source, only as provoke thoughts.
But that is a big shift, indeed. We have been taught, nearly aggressively during last years, that certain types of sources are The Truth, and "alternative sources" are no good even as thought-provoking, so they should be ignored (even better, banned, but that doesn't play well with the idea of freedom of speech/press). If we enter a situation where any source is equally good input material for our own thinking, where nothing is trusted at face value, then... I think this is very good!
If AI helps us to reach the saturation point in meaningless noise, then great!
