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?
