This is always difficult terrain for looking into the crystal ball.
I think the most optimistic scenario is that we're going to create a transition whereby people will observe more and more deceptive material and may turn back to more trusted sources that have a long-standing code of ethics and the resources to do the careful work of compiling and presenting the news in compelling ways. That's the most optimistic view.
The more pessimistic view is that the information ecosystem becomes overly polluted to the point that people tune out. As a political scientist, I worry not just that people might believe false things, but that they also don't know enough. I worry that many folks are not interested in politics, as it is very much their right and perhaps also their privilege, but the danger is that as more and more people tune out because they cannot distinguish between true and false, it further degrades our democracy.
