People our age only have a few childhood pictures, and they are warped by time on analog media. Those pictures of us as a kid look really old because they are naturally filtered. Soon people will wonder WTF old-pic filters are for, and some historian will have to explain why it's blurred and the colors are faded. Also why did people have clothes for each decade?
Our kids, by contrast, have had pictures taken of them every week at least. With metadata so you know where you were. And they're digital images that won't fade. When our kids are 40, they can look at an archive of how they looked pretty much every week of their lives. Not only that, they can already search the archive for particular situations.
