I'm not sure that deepfake technology would be an appropriate target for any specific action, only because it is one in a very large belt of tools available to people who are trying to manipulate people through social media. Through the ways that both of the other speakers have spoken about, our brains are kind of wired to heuristically solve problems that we can't possibly logically solve because there's so much information being thrown at us at all times.
I worry, truthfully, more about the intent of misinformation and disinformation. I truthfully worry more about that than the specifics of deepfake video. This is only because—again, I go back to my security camera footage—you don't need to have a very sophisticated video or fake video to convince people that something's happened. You don't need to have a very convincing photo to convince people that something's happened. You can use a real image just as easily as you can use a fake image.
