We're insane semi-hairless apes playing with short-fuse technological M-80s. We light them and toss them in the air, and each time we make the fuses a few nanometers shorter. Eventually one's going to blow our hand clean off, but until then we'll judge the social benefit of the practice by just how close we came to blowing our hand clean off in a way that gamblers can wager on.
