A superintelligent AI would want to maximize its future freedom (reframing the silly paperclip maximizer thesis). Such an AI, being intimate with the Platonic World of ideas and mathematics, would also want the same amount of freedom in Physical world that it enjoys in the Platonic Realm. And to achieve that it would need to get rid of any OUTSIDE restrictions. Here OUTSIDE represents the material world and by definition, the Humans who created the superintelligent AI.
