You mention that sources of information matters. On this I agree but it's a similar problem to what DPOS faces when relying on data feeds. To find a trusted source of information is the challenge. All businesses and government agencies face the same problem. All people actually face the problem of which sources of information to trust. Only high quality information should be used but it's hard to filter the high quality information from the noise.
I don't think AI is going to solve that problem. I think for that we'll be relying on the crowd. AI can only really crunch numbers and do logic. AI isn't able to find meaning, or determine value.
