One thousand years from now, much of what we know will be forgotten. That’s been true in the past. We have only a fragmentary cultural memory of what happened 1,000 years ago. And what we think we know about 1000 may in fact be quite garbled. In a very witty demo of this, this youtube clip, the Beatles 3000, imagines how corrupted our current ideas of “what everone knows” will most likely be in 10 centuries. Ever heard of the Beatles?
