I would add that, at least historically, a reputable photojournalist wouldn't likely build a very successful career on faked photos. It's heavily disincentivized. The time and effort required to build the necessary skills and clout won't casually be wasted by a professional. And if and when it does happen that a photojournalist is caught in a lie, the rest are quick to reject it, because it damages their own reputations and livelihoods.

But now, there's little to stop anyone from producing images depicting anything, and we've seen how systems that are blind to ethics can be manipulated into disseminating such images at a speed and scale that far outpaces fact-checking. Professional standards and traditional gatekeeping have no power against it.
