Before photography, we knew something was truthful because someone trustworthy vouched for it.
Now that photos and videos can be faked, we'll have to go back to the older system.
Ah yes the good old days of witch trials and pogroms.
I am no big fan of AI but misinformation is a tale as old as time.
It was always easy to fake photos too. Just organize the scene, or selectively frame what you want. There is no such thing as any piece of media you can trust.
