I think there is something to be said about what is worth archiving. I don't know what it is that should be said though. It seems weird to me that as a society we might be saving things such as a 10 hour video of white noise for another 100 years rather than some personal blogs. What is and isn't worth saving?
It will probably end up being the most popular things, the most viewed or read. More copies of it, more likely to be archived. This reminds me of books. I’m sure the majority of books from over a hundred years ago are lost because they weren’t popular. We haven’t really noticed their absence…
Kierkegaard, Thoreau, Dickenson and Melville, for instance.
If their works had been lost, "we" probably wouldn't have noticed any of those absences either.
