I see this worry about the historical record disappearing, and think it is misplaced. We have plenty of knowledge of civilization from hundreds of years ago, despite a near total lack of written records at the time.

And frankly, it's probably a good thing that a lot of records disappear. How many books about WW2 can you read? Is it remotely useful to keep all the accounting records of every company for future generations? There's a lot of angst about half of the silent movies having disappeared, but let's be honest - most of the silent movies were trash churned out for a quick buck.
