The main problem with digital content is that you need a complicated electrically-powered device to read it. Books can be read without high technology; you pretty much only have to worry about fire, moisture, termites, paper-eating microorganisms, acids in the air...hmm...maybe paper-based books are just as bad.
But seriously we need some ultra-futuristic answer to how to store and keep the knowledge we've acquired for much longer than we can now. Something thin but sturdy (silicon-based?), simpler than electronics today and powered by solar energy.
Its mind-boggling when you think about the number of books and other media there are available today and not just in the U.S. I wonder if something so mundane (now) as an episode of Johnny Carson's Tonight show will even exist 500 years from now.
And to think, it hasn't even been 100 years really since electronic-based media has been around and now look at how much of it there is!
We surely live in amazing times...Who knows, if this nfo isn't preserved we may be thought of as a lost Golden Age in a few thousand years.
Ugh...sorry for the rambling, was bored and got into 'deep thoughts' mode.
