When I was 14 years old, in 1962, I was a finalist in the State Science Fair, which was held at the University of Oklahoma. While the judges were examining our projects, the university gave us a tour of the various science buildings and exhibits on campus. I remember how proud the tour guide was of the university's awesome new multimillion dollar Computer Sciences building, a huge, noisy place filled with banks and banks of chattering relays and flashing lights.
Today I have more computing power than that in a device that will fit in my purse.
