Vetting, moderating ... none of them scale well when done manually. The solution I see is that everyone have their own AI filters, customised as they see fit. You can include or exclude specific people and topics, make it as diverse or narrow as you like, allow challenging opinions or not. One of the filters can be to detect AI bots. Don't make the world conform to you, be selective and just skip the bad parts.
I think people are going to trust their own AI tools that are running on their own computers more than they trust other people and especially other AI. We already know we can't face the future onslaught of information with the old methods, we need help. User controlled AI is going to be our first line of defence and our safe space, "a room of one's own" where there is no tracking and thought policing.
With the advent of large language models we already have that, indirectly - the LM is a synthesis of everything, but we let it generate only conditional to our intentions. All the view points are in there for us to reach, it depends on us how we relate to them.
AI should be like a cell membrane separating outside from the inside. It should keep the bad stuff out, take the necessary nutrients and nurture the life within.
