However, the same lessons don't extrapolate into the future. We are leaving digital artifacts, which are (potentially) immortal. It's very possible that a historian in 3000 A.D. could listen to all of the Beatles' recordings, with exactly the same quality that we can listen to them now. He could watch their movies, and read newspaper articles about them.
Part of what makes another culture feel old or distant is the fact that aging is a lossy process - their paintings fade, their buildings collapse, and their books are lost. How will things change when our artifacts (e.g., the web) can be perfectly preserved indefinitely?
