"I am philosophically committed to 'mechanistic naturalism', from which follows the conclusion that anything humans can do, machines can in principle do, too. In many cases we already know they can do it better. Whether they can do it better in all cases remains to be seen, but I wouldn’t bet against it. The precautionary principle should lead us to behave as though there is a real danger — a danger we should take immediate steps to forestall. Unless, that is, we think robots could to a better job of running the world than we can. And a better job of being happy and increasing the sum of sentient happiness" (Richard Dawkins)
