> As for politics and fact-checking, personally I just don’t care. If you do, then sign your damn video with a public key already and check if a video matches it. I think we're going to see a lot of things like this, soon. Signing for ownership, definitely, but also lots of other tech tricks. We already have livestreaming, which prevents fakes in the moment. If you upload a video as soon as you take it, you can put a Google or Facebook vouched timestamp on the content. If you don't want to rely on their reputation, you can share a hash of the video content before a deep-faker would have had time to edit the content. Timeless content like a video of police violence is tougher to prove, and fakes will be very hard to disprove, but the idea that convincing-looking fakes obviously destroy trust is a failure of imagination.
