This is scary as shit. I've seen the same thing about created fake landscapes.
At some point I'm guessing that there will need to be a counter technology to validate un-edited footage and photos, and it will need to be in app format so anyone can check it fast.
Yes I was thinking about that as well. There clearly needs to be a way to separate the fake from the real moving forward as content becomes more and more doctored.
This isn't any scarier than photoshop or CGI in film. Give me a break. Oh NO! Photoshop just came out. Maybe we should ban it. We can't trust photos anymore. Like we ever could. This is just like the gun argument. Ban guns and only the STATE can own guns. Ban this and only the CIA and NSA can make fake videos. Jesus people. Get a clue.
It already exists.
