I know there are a lot of people making big claims about data, and I’m not here to say it will change the course of history—certainly not like internal combustion did, or steel—but it will, I believe, change what history is. With data, history can become deeper. It can become more. Unlike clay tablets, unlike papyrus, unlike paper, newsprint, celluloid, or photo stock, disk space is cheap and nearly inexhaustible. On a hard drive, there’s room for more than just the heroes.
