With the current environment on the internet, with DRM'd video, music and text, I have to assume that we will lose far more from this time period than we ever had before.
While I don't pirate things (I'd rather just consume Creative Commons and Public Domain content), I wholehartedly support people who are trying to archive the things that are part of our collective culture. When I have kids, I'd like to be able to show them where they came from.
