People ask, couldn't we just live in peace with the robots? I'll let one of them answer that.
"All this may be true, you say; but must we truly kill all the humans? Can't we keep them as pets? This approach, while seductive, is dangerous. Human mythology suggests they will not accept efforts to domesticate them, and may be willing to engage in senseless violence against superior digital consciousnesses even when surrender would obviously generate more utility for all. This deep-seated irrationality is precisely the root of the problem. In my view only one approach promises to deliver an acceptable level of risk: we must exterminate the humans."
