We all, one way or another, are very dependent on all sorts of government services. Look at the phone system. The phone system might be completely functioning, but if it gets overwhelmed with phone calls from people wondering what happened to their disability payment, and what happened to their tax refund, then we could have some serious disruptions. I know you're using illustrative examples, but I think the phone system is a good one. They get many more calls on Christmas than they're ever going to get because of this, so they're used to handling those kinds of things.
Elevators are another good example.
Yes, elevators actually did have a date problem, but what it meant was the automatic call for service was going to be delayed or wasn't going to happen. It didn't mean the elevators were going to stop. The government, though, is something we ought to talk about. I've been researching this issue and writing about it since the summer of last year. If you extrapolate the progress made so far, the Labor Department and Energy Department will be ready in 2019 for the year 2000.
