But it's the same. I think that the fact that people are so scared of deep fakes show they are not critical enough of what they are already shown. Images lie all the time.
Eh, maybe. People watching cinema "know" it's not real, even though propaganda is a thing I guess. Deepfakes won't alter anything with regard to that though, whether it's a deep-faked actor, a CGI monstrosity, or just a look-alike actor in makeup.
although you are right about video 'evidence', editing, cuts, and carefully muted dialog can alter things to the point of being the opposite of what was being filmed - an unprovoked attack can become self-defense or vice-versa, etc. Again, deep-fakery is just another tool in that unsavory toolbox, not anything paradigm shifting.
