Nothing could be worse than rushing too blithely into a new technological era, becoming over-reliant on new tools without adequately exploring their failure modes. Y2K has had exactly this effect. Millions of lines of code have been re-examined. This new capability, created expensively, under quasi-war urgency, needs much more development. In fact, a whole new type of industry has arisen that makes its living by catering to scary scenarios about what might go wrong.
Optimism makes sense.
If civilization goes on, though, I get points for positive thinking. Now there is an old rule of thumb. In the end, costs come down to wages. That works out to at least one hundred million man-years spent working solely on Y2K fixes. Don't get me wrong.
