If such a thing as a super intelligence existed, why would it operate on matter in the physical world? Animals do physical world modifications because we're biological and need shelter etc. A super intelligence would quickly understand everything there is to know about the physical world and just move on meta-physics. It would just be like an "orb". Humans are already bored with the physical world and thus much prefer being in virtual spaces, look at everyone just starting at Instagram. IMO This idea that it's going to eat all the atoms on Earth is part of the anthropomorphize of something mythological. Exactly how we imagine God as a dude with a grey beard.
