Is this really why the Y2K problem has a long shadow? "Globally, we handled the very real issues posed by computers being unable to comprehend the passing of the millennium so well that the average punter didn't notice the few systems that didn't get updated."
My recollection is that in fact there were no real issues, or almost none.
In fact, the Y2K BS storm inflated the computing market which then blew up in the dot com bubble.
The implication that Y2K was a success, rather than a much hyped non-event is certainly counter to my experience at the time.
