The issue is that far too many people don't have a clue about HOW to think.
A lot of folk simply have never learned how to think. We see that here quite often.
They claim that the fact that some projection have not yet happened yet seem to totally misunderstand, seemingly intentionally misunderstand, that the projection were the very things that drove changes that have so far mitigated some of the direst predictions.
Yet so far the trend actually continues to point towards those direst projections and what reality show is that human efforts have changed the timing but so far there is no indication that we have done anything more than postpone the consequences.
And I was one of the programmers not only dealing with the issue but working with state government IT people from all over the US to make sure that any Y2K crisis was only ripples on a summer pond. The Government Information Management Sciences group was active in identifying issues unique to each mainframe computer system and programming language as well as to the entirely different threats faced in the mini, micro and desktop environments.
The threat was very, very real and the cooperation and information sharing that resulted in the very minor problems that did ensue put paid to the absurdity of your positions.
