question please, o great writhing amoeba of collective extropian arcania: is anyone here familiar with the terms m1, m2, m3, civilizations? i think i saw it here once. the definition is something like: an m1 civilization is one that has exhausted the resources of a continent. m2... a planet? where does this terminology come from? thanks! spike
