Anymore? Photos have always been imperfect approximations of the truth that should be considered with appropriate skepticism. Photographers choose when, where, and what/who their subjects are, when they frame their image and release the shutter. Editors choose which ones to include in a story. AI may be doing us a favor by making this more obvious.

As with other media the solution has been and still is corroboration. Are there several, independent photographs of the same event? Great! Otherwise, treat with due skepticism. This is good news, as it doesn't require all the tech ("fingerprints and cryptographic signing of images from the cameras that took them") that Mosseri proposes.
