So you think that when we finally have smarter than human AI, it's just going to make completely objective decisions?

First off, we'll never let such an AI to be completely objective, because, well, the paperclip scenario. And second, the AI will be about as "objective" as Google search is - in other words, not really. At the end of the day it's still humans that decide the algorithms for Google search, and it will be humans that decide the algorithms for the "smarter than human" AI.
