I predict that nothing too crazy is going to happen, leaving millions of people disapointed. It is the end of an age, and the beginning of a new one, but who said everything has too change in one day? Why couldn't it be a more gradual change that lasts over a period of months?
I remember years ago my now college age daughter was 9 years old, and she rushed outside on the first day of spring expecting to see leaves on the trees. I had to explain to her it just didn't work like that, the change happened gradually.
So what are we changing too? I don't know, but I don't think that this time next year we will be broken down into a fuedal society going to war over the last few cans of tuna while a bunch of rich guys wait things out inside a cavern deep inside the bowels of the Earth. Even if I knew for sure a bad earthquake was coming, I don't think I would want to be in a cave that could collapse on me.
If I'm wrong, jump on this post after the fact and point it out to me. Of course the very ability to do that would mean that I was correct all along.
