I don't understand the argument that crypto solves the problem of verifying real vs AI-generated content. how exactly does crypto help here? genuinely curious

The year is 2035, 80% of videos on YouTube are deepfakes. POTUS "saying" all kinds of stuff they don't say. A video appears that's signed by POTUS.eth, which is an actual Eth address controlled by the White House. You watch the signed video, knowing it's real, knowing it's not deepfaked by some actor.

ok, so what happens if a politician actually does/says something horrible, and they just refuse to sign the video of them doing the horrible thing? who do we trust in this case?

Presumably you trust the journalist or reporter that released the video. 

It’s all reputation based at the end of the day.

/max • /bracket • @quickcast • /coys • maxp.co

yea that’s my point tho - if it falls back on reputation anyway then the crypto part isn’t relevant

Cryptography is a solution to direct attestations/claims, as many wrote in this thread.

Reputation helps when there is indirection. If the direct persons/subjects involved don't want to attest, then the best you can get is third-parties attesting.

Did you change your question to how crypto can help with reputation?
