It is about the shift taking place in our civilization right at this moment. Not that shifts are anything new to us - they have been happening since the dawn of time. That is how we hopped onto the ground from the branches of trees and came to live in the city.
But the present shift is a cumulation of all the earlier shifts. As the next shift will cumulate this one with all the rest.
Please switch on your speakers while you watch this brief (about six minutes) presentation. For the background music (a score from "The Last of the Mohicans") is haunting, and quite apt to its content.
