Computers and computing are all around us. Some computing is highly visible, like your laptop. But this is only part of a computing iceberg. A lot more lies hidden below the surface. We don't see and usually don't think about the computers inside appliances, cars, airplanes, cameras, smartphones, GPS navigators and games.

Early in the 1990s, I flew alone in a dandelion-yellow, single-engine, 180-horsepower Piper Cherokee from Westchester County Airport in New York westward to the Rocky Mountains, landing and refuelling a good many times in middle-sized cities and towns along the way.

I remember Detroit feeling really unsafe, feeling scared a lot. Our house was broken into, our car was stolen, we had to get a watchdog, we would get beat up in the street, I had my bike stolen. There was just a lot of real anarchy on the streets and sidewalks.
