This is a very quiet, unspoken problem that is very quietly advancing.
I worked for a tech company where we were scanning and digitizing a library of books as old as 100+ years, and yet the concern of the professional librarians were that they were utterly sure if they kept the books in a carefully controlled environmental room, the books themselves could easily last another 100 years, but we could not guarantee that even with every fail-safe we could install in the digital version that the data would last anywhere near that long in digital storage.
Apply this to the unbelievably vast digital content that Uncle Sam or Amazon or even your local uitility maintains, this can be a bit unnerving. Not to mention kids growing up today won't have a terribly embarassing stack of pics of themselves when they were in Little League or in braces like we do.
You know, might not be the worst thing if Amazon and Google's databases got utterly fried. Just sayin'.
That said, I do need to print out a ton of photographs of my son.
