The way we look at pictures of our grandparents and great grandparents may go away as we stop printing picture and our digital records get deleted shortly after our deaths. In a generation or two, there may be a whole generation that has no access to their historical family pictures.

Edit - Lots of great comments. I'm referring to a scenario similar to my fathers death. For years his pictures were on his accounts and on his computer. When he passed, the accounts closed, the computer was lost in the family. The old physical albums are with a family member and are basically inaccessible. I have maybe one or two pictures of my parents and I expect my children will have less. Each generation will lose data, even as we personally generate more individually. My children may not be interested in maintaining thousands of pictures I have of myself and people they barely, if ever knew. This may compound generation to generation.

I was not referring to global apocalypse where all data was lost.
