This is a most excellent place for technology news and articles.
This will eventually settle into a new era of going back to times where people didn’t have cameras in their pockets.
People eventually will start believing only other people who have some reputation at stake. Like journalists and similar.
It won’t happen overnight. A lot of harm and bad will happen before we learn it.
I think it’s more likely that we’ll need some cryptographic verification at time of recording to be valid, or a physical medium like film to be present. So perhaps film cameras or discs (non rewritable) have a resurgence.
That can all be faked.
It’s a hard problem, but there is likely a way with cryptography and upload to server that would be verifiable. Honestly this may be the only legitimate use of blockchain.
It would require a centralized authority to work in any meaningful way.
Not really
You can publish public keys and sign the videos with private keys
It still doesn't prove the video is not AI, just that it comes from a specific source, like a press camera
You can always retroactively sign. Or it would require secretive hardware managed by some centralized authority, and would be exploitable by at least nation state actors.
Signing it doesn't mean "not modified", it means "yes, this video is from that person", basically, nothing more. However, that signature is something that can't be faked.
At least with that you can state that a video came from a journalist themselves. If that's enough to trust it, is another question
