Human interaction is complex
The Internet itself is certainly a Good ThingTM. Social media can also be a good thing, but the bitter truth is that humans are, as always, the weakest link.
Technology, as impressive as it may be, will never be the solution. Between arrogant billionnaires who believe that their opinion is more important because their bank account is larger, and the assholes who have the technical means to impose their will on others and do not hesitate to do so (yes, the overlap is rather large here), there is only one solution :
Education. Teaching people to think for themselves. To pit their ideas against historical fact, and deduce on their own whether or not their opinion is right.
The exact thing our governments are currently dead-set against, because that would mean that manipulating opinion is harder, which would be an impediment to their goals - goals which rarely align with the goals of the basic human population, which is mainly to live in peace, live a full life with a loving family and die knowing that you have loved and been loved, and have avoided starvation, death and strife for your family and your loved ones.
Some people just love to watch the world burn.
I don't see how technology, much less pseudo-AI, is going to help here.
