As a futurist, I’ve often licked my chops over rather grim possibilities. But my lasting fondness for the dark side is a personal taste, not an analysis. I’m frequently surprised, and when I consider the biggest surprises, I’m heartened that they were mostly positive. The Internet, for instance, crawled out of a dank atomic fallout shelter to become the Mardi Gras parade of my generation. It was not a bolt of destructive lightning; it was the sun breaking through the clouds.
