So I have this basic theory that all learning curves have the same shape. And if you compare that shape to the evolution of man and our abilities, then two possibilities arise. The first is that we are really still in our infancy and that we have a lot more to discover. And the second is the Battlestar Galatica possibilities, that we have been here before and this will happen again. Or as I would say, we get to a point where we discover some scary things and destroy ourselves to the point where we have to start over again, back to the beginning of the learning curve.
