Since the human brain is not capable of recursive alteration of it's source code, and remains almost identical to the first conscious brains evolved 100,000 years ago, one must wonder if it is a tool capable of (or appropriate for) designing a friendly AI. In a time when the parabolic rate of increase in information far exceeds any possibility for natural selection to produce brains that do not rely on the evolved emotions and motivations you discuss, how can such a brain be expected to program the AI source code appropriately, when that brain is not capable of doing the same for itself? That is, how can that brain be expected to be capable of choosing what actually is "friendly", in light of its evolved state?
