A risk is that it will give people a false sense of confidence that they are viewing real content. The only way out of this mess is cryptographic methodss (based on hardware in cameras) that can allow end-users to verify photos as real and then we assume every other photo may be AI.
Cryptographic components in cameras have roots of trust that can be compromised as well. Also, photos can be staged (many famous examples of this).
The only real solution is to build social infrastructure that helps people identify the trustworthiness of a source. Some efforts are being made in both the centralized and decentralized directions.
It turns out librarians and teachers teaching media literacy and critical thinking still has great value!
