Would it be too optimistic to say that if we can create realistic videos of anyone doing anything, the general public will not believe in videos as evidence anymore anyway? And so it wouldn't matter soon, except it would matter for a different thing, namely we'll lose the ability to use legit videos as evidence of anything. On the other hand, it has been possible for an extremely long time (millenia) already to create text of anyone doing anything, and in general it seems we can still trust text mostly (and can distinguish somewhat well between false and reputable textual sources), so maybe it's all reputation based, also for video in the future.
