Could be, and maybe the motivation varies depending on the subject of the photo.

For example, I can go a whole vacation without taking any pictures. But with my kids I love to take their picture and get videos because they grow up so fast and it's fun now to go back and revisit a time when they were younger. They also love to see themselves when they were an age that they don't remember.

I think it's just a manifestation of FOMO. People fear they will one day regret not having more pictures, so they take more pictures than they might have otherwise "just incase."

It’s interesting that individuals have this desire- the goal should be survival of the species not of an individual

Like insects? No, thanks.
