War, famine, and pestilence are outside the realm of our first-hand experience. We get up expecting that today will be pretty much like yesterday, and tomorrow will be pretty much like today. In the past, people expected their lives to be periodically disrupted, and they planned accordingly. In the past. people always prepared themselves against storms, winter blizzards and summer tornadoes. No one questioned the wisdom of preparing for emergencies.
Insurance is based on a similar notion.
We should cancel our policies. No, we would be happy if we never had to use it. Y2K is no different. In essence, Y2K is sort of an insurance policy. If you don't end up needing it, so much the better.
