Unlike other creatures humanity can control the course of evolution and change our very natures. I say if we can control it we should aim for betterment rather than let the natural outcome dictate our path. Civilization goes through a form of natural selection the natural outcome is for our civilization to die and a another one to take its place. Betterment is not a criteria for natural selection, survival is... and if cavemen replace a technological civilization because of survivability then we have lost from a cultural standpoint. Aim for something better.
