This is just an iteration of the same overreaction that has been occurring since the days of splicing audio tape together.
If anything, I would argue malicious editing of REAL footage, which already occurs in media outlets today, is far more frightening than the possibility of having a deepfake video, though it might be another tool in that slimy toolbox.
Convincing enough deep fake + the 24/7 news industry + Twitter rage machine combined will at some point overreact way too fast and too hard and someone will get actually hurt, maybe even killed.
Actors have had clauses for not using their likeness for a long time now, if their face is 3D scanned, the use cases are carefully limited. They can't just put Brad Pitt in a random commercial even though they have the scans of his face and body and can find a voice actor.
Boy, that escalated quickly.
Bruce Willis got paid an insane amount of money for his deepfaked face to appear in a Russian commercial. He literally got paid a couple million dollars to do NOTHING except agree to his likeness being used.

For example, let’s say you want to make someone seem like a jerk… in 168 hours, everyone is going to have at least 30 minutes of actions that, in a vacuum, make you look like a jerk. By choosing only to show actions that contribute to a certain narrative, you can completely change how someone appears to behave.
What we need is better inoculation to psycho misinformation politics
We already do this with photos. We don't necessarily worry so much about what's in the photo as who claims the photo is real and what the chain of custody was.
The same will be true for video evidence, even if or especially if we start stamping videos with tamper-proof signatures.
