What I see is the tens of thousands of people in troll factories producing content for 3/4 of the world population ready to believe whatever they see in the TV.
I think a more likely scenario is that people will be so used to it that a lot of people are going to have trouble believing that real things are real. Conspiracy theorists already suffer from this and it's going to get so much worse.
I think in the initial years there'll be some major incidents where a fake thing gets major attention for a few days until it's debunked, but the much larger issue will be the inverse.
