Am I too naive in thinking the answer is rather simple? Cryptographic proofs (digital signatures). For text this should be trivial and for streaming video/audio you can probably hash and sign packets or maybe at least keyframes or something?

I think this is naive, is it just kicks the can. How do you trust that the signer is human?

True, I can only know that the owner of the private key signed but not how the document was created. But I suppose there is some trust involved that a person I know who signs doesn't sign some AI generated stuff. To establish the initial link, I suppose we need something more mainstream/scalable than the old key signing parties I remember from CCC etc.

But at least for friends and family it should be possible to create some flow where every member has a key-combo and you trust them to only sign stuff they wrote etc. and have local mini-keysign parties.

		Do we need new key signing for friends/family? I can trust that all messages coming from a friend/family’s account originated from them, or else their account was compromised. I don’t see how a ‘non-ai’ key adds enough more trust to be worth it.
