Although it regularly discusses the possibility of superintelligences with the power to transform the universe in the service of some value system - whether that value system is paperclip maximization or some elusive extrapolation of human values - it seems that Less Wrong has never systematically discussed the possibility that we are already within the domain of some superintelligence, and what that would imply. So how about it? What are the possibilities, what are the probabilities, and how should they affect our choices?
We definitely do live in a world where there are representatives all along the intelligence spectrum. We also live in a world where the difference in the mental life of an infant and an adult is so great we adults can't remember or convey what it was like to be infants. Then there's humans and the other primates. Plenty of intelligence disparity relations already in play. If there is a level up it will have the same wonderful and terrible relation we have with each other already.
