There is no guarantee that greater perspective-taking capacity will be matched with equivalent action. But presumably greater empathetic concern makes such action more likely. [cf. Steven Pinker's "The Better Angels of Our Nature". Pinker aptly chronicles e.g. the growth in consideration of the interests of nonhuman animals; but this greater concern hasn't (yet) led to an end to the growth of factory-farming. In practice, I suspect in vitro meat will be the game-changer.]

The attributes of superintelligence? Well, the growth of scientific knowledge has been paralleled by a growth in awareness - and partial correction - of all sorts of cognitive biases that were fitness-enhancing in the ancestral environment of adaptedness. Extrapolating, I was assuming that full-spectrum superintelligences would be capable of accessing and impartially weighing all possible first-person perspectives and acting accordingly. But I'm making a lot of contestable assumptions here. And see too the perils of: http://en.wikipedia.org/wiki/Apophatic_theology
