Want court evidence of your wife cheating? Fake grainy hidden camera video. Want to discredit a politician? Here he is picking up a male escort and using racial slurs. These sorts of things could be used to start wars.
Sure, deeper analysis might prove that this video isn't real, but that won't stop the immediate public reaction and response. The knee-jerk reaction to what the public sees is the end-goal. I'll bet good money that this technology plays a major role in future elections.
