I personally know people who were laughing all the way to the bank with the money they made from panicky people and institutions (say, hospitals) "correcting" the Y2K problems with their computers and software.
But there wasn't a political scam going on with government grants going one way and political donations going the other way. That's what I mean by "scam". Global Warming was a scam - an intention lie to defraud.,,
Y2K was a scam for the vast majority of applications. It made a lot of money for IT consultants and some companies. Those that spent tons of money had no significant problems. Those that spent little or no money also had no significant problems. The problem was widely inflated by IT vendors and consultancies that saw it as a quick way to make a buck. It’s ever been thus, and will continue to be so.
