Trying to be as least cynical as possible, imagine if you were a party with 3 or more people, and you really wanted a nice pic like that to commemorate the night, but never got to take one all together because someone left early, and you were in the bathroom when they announced their departure.
Yes, it's a major first-world problem to not get a photo, but to the right person, it could mean a lot to them to "fix" the photo they took with A and B to add C to their 'rightful place.'
and then as you look back at that wonderful night you "remember" with all your friends, you will reinforce a false picture and reality strays further
This is such a contrived imaginary situation that is pretty divorced from reality. No one wants a fake AI photo to commemorate a real event.
But still what's the point? To look back on false memories that didn't happen?
What's the point of having a photo like that?
Is spending time with your friends not enough in 2026? Do we must provide photographic evidence of all the fun you have been having or it did not happen?
