"Dig deep enough of a hole and you'll find yourself at the other side of the earth, facing the same problems."
I'll keep this short; I find the entire concept of "World's End" scenarios to be the magnum opus of proof of what society has become in civilized parts of the world. Civilized in the form of safety. Up until recent years, mankind has almost always been facing one form of annihilation or the other, it was a common trait, something given in the world. We, the last 2,3 generations have been blessed, and ironically enough, the human mind cannot fully process the concept of us living in safety.
"From safety to where?" is an old Joy Division quote, that might be applicable.
But beyond teenage rave fests in early/mid december, I really couldn't care less for these self-proclaimed "theories". We've heard it all before, from the semi-realistic prospect of y2k with the idea that most computers couldn't handle the number "2000" (as an IT-specialist, myself, I can guarantee that this was, as the time, an honest-to-god safety risk concerning railroads, airports and the stock-market; but not a doomsday scenario) to far more abstract concepts such as 2012. Let's be honest, nobody would take stock in this unless they, at some level, hoped the world would just cease to be.
Now, there's a million of theories, all which have been struck down or shrunk down at the approach of logic, so all we've got left is superstition.
Now, indulging in these matters only seem to increase the amount of people who do worry about it, and as such, just feeding the masses with even more ammunition. Yeats spoke of a concept called "Hollow people", and this applies with room to spare. The most basic concept of the idea is people who need to absorb structure-less, useless information in order to function as a human being, lacking the integral core of what makes the concept "I think, therefor I am" functional.
Just ignore talk of it, and laugh it off. It's for the best.
I'll agree with "therumancer" on one point, though. It's a mighty good excuse to build a survival gear. But that's what it is, an excuse, nothing more.
- Also, just to add on what the rumancer said; the Maya did, by no mean, actually predict that the world would end at 2012, this is just an uneducated, common-day assumption. Infact, that was the time their Calendar simply ended, and a new "age", so to say, would commence. It's said that's the time when their god, which ironically enough, is assumed to have been the very original of horoscopes, would return to Earth in part of their 5 Life-tree belief. Every god was a mish-mash of characteristics that resulted from a simple, mathmatic combination of their own calendars.
So, to sum up; their belief was at the end of 2012, their calendar god is going to return down to them and usher in a new age. Talk about setting the expectations high for a first date, huh?
