The Quest For Superintelligent AI: What Can We Infer?

It’s no secret that people like Luke Muehlhauser endorse the creation of superintelligent AI as a means of saving the world. For me, a few questions arise.

1) Isn’t this a direct concession that human intelligence alone is incapable of creating a “perfect” world?

2) Per 1, mustn’t people like Luke Muehlhauser agree with me that a “perfect” world must follow given obedience to an all-knowing God Who has our best interests in mind?

3) What do you think people like Luke Muehlhauser would do if superintelligent AI came to conclusions that conflicted with their own moral preferences? For example, how do you think they would respond were AI to condemn homosexuality?
