KJS, I've spent most of my working career in the computer industry, and I think the possibility of widespread catastrophe as a result of the Y2K problem is extremely remote. The problem is well-understood and LOTS of manpower has been and is being thrown at it. The real difficulty is simply that there is so much ancient, undocumented code still running on large institutional computers that some instances of the problem will go undetected until they fail. That will no doubt happen, and could cause some annoying computer errors and bureacratic snafus, especially from the government and financial institutions. But the fear that this could bring about the collapse of the world's economic infrastructure is, in my judgment, just that -- a fear, but not a realistic one.
There are many people, not all of them religious fundamentalists, who are determined to see the coming of the millennium as an "end of the world" scenario, and the Y2K problem is just one of the ways of imagining that.
My two cents, anyway.
Personally, I see the "end of the world" coming too, but in a very different way -- more like the end of the world as we have known it for the last two thousand years -- brought about not by economic collapse but by a global change in consciousness. And this is happening already, right under our noses. The people on this very discussion forum are carrying on lively conversations about spirit and astrology with each other from many separate countries, all over the world. Instantly! This is a real "global nervous system" in the making, right here and now. It's hard to see how radical a transformation this is bringing about, because we are right in the middle of it, but I think it marks a turning point in human civilization comparable to the discovery of fire, the development of agriculture, or the invention of language. It will turn us into a new kind of humanity. And with the growing connection of minds 1-to-1 instantly throughout the world, I think the change will have more to do with inner awareness and expanded consciousness than with external structures like governments and economies.
My other two cents.
