One point that is often lost on the discussions of fake video/"deepfake" is that this development won't only make it easier to fool people into believing something that's made up, but it might also make people more distrustful of things which are actually true.

When it's been spread out enough that anything can be doctored to an indistinguishable extent, everything becomes deniable by those being caught, and the skepticism explosion is going to raise the bar for investigative journalism / actual evidence to standards high enough that few will have the resources to produce them.
