We're a few short years away from a media future in which computer generated video fakes will be indistinguishable from real videos.  It's hard to imagine the full consequences of professional liars in possession of such software.
For example, a large part of the country is currently losing its mind over Hunter Biden's blurry penis pictures.  Imagine what would happen if somebody made a convincing fake video of Hunter Biden meeting with a Chinese spy to sell secrets he got from Joe Biden?  Or a convincing fake video of trump's infamous pee tape?
Or, much more frightening, imagine fake videos of important things, like fake missile launches, or attacks across a border.
We're on a collision course with this technology. >

I thoroughly believe technology like that should be banned. Think of the implication where video fakes are indistinguishable from the real thing. You could take any random person’s face and put it on anyone having sex. It couldn’t just hurt politicians but ordinary citizens. 
I know that going with the sex deepfake is a bit cliche but there’s no telling the amount evil you could do with it. It’s too dangerous to be in the hands of creatures as flawed as human beings. >

I think it would deeply affect our political discourse in a surprising way. People will eventually just not trust anything that does not fit their narrative (we are almost there right now). >

Well, everyone kind of agrees mass media has allowed people to invent confining, pigeon-holed narratives for their worldview. You’re right, but your view isn’t surprising. 
Unrelated, but I’m glad my anti-deepfake comment got two upvotes. That stuff is truly disgusting
