There's a shockingly large number of people who aren't even convinced that election meddling took place in 2016, or that propaganda was disseminated to many people on social media, despite unanimity from US intelligence.
If we as a society can't all agree that these things even happened, how can we hope to properly educate people on the existence/prevalence of fake video? It seems like common sense to many people, but we can't assume that everyone will accept these truths based on the political rhetoric we've seen in the last few years.
And yet, fake news does seem to be a problem. Checking provenance of facts and statistics is often skipped, even by journalists, let alone on Twitter.
This suggests that people will have lots of fun resharing deep fakes and won't care much that they're fake, as long as they express some emotion that they agree with.
Give people a fake that they want to believe in, and it's going to be very hard to talk them out of it.
Previously it took at least one CGI artist to convincingly fake video, probably several. This inherently limits how much of a problem it can be, because it doesn't scale. AI scales.
I mean- either deep learning AI automation is going to be important and useful, or it isn't. If replacing all drivers with robots is important, then automated turnkey fakery has the potential for disrupting something, isn't it?
