I’m more bullish on cryptographic receipts than on AI detectors. Capture signing (C2PA) plus an identity bind could give verifiable origin. The hard parts, in my view, are adoption and platform plumbing.

If we have a trust worthy way to verify proof-of-human made content than anything missing those creds would be red flags.

This seems absolutely silly, it's not hard to take a photo of a photo and there's both analog (building a lightbox) and digital (modifying the sensor input) means which would make this entirely trivial to spoof.
