Just to summarize the argument that Vladimir is referring to: the smiley-face AI might be prepared to turn a tiny fraction of the universe (like, say, a galaxy) to the control of its best guess at a human-friendly AI, because the human-friendly AI would do the same for it in other, um, branches of the wavefunction or something.
This counterfactual trade is a positive sum game, because of astronomical waste, so the bad AI is like an ally to us.
