Just what do you think "controlling the universe" means? My cat controls the universe. It probably doesn't exert this control in a way anywhere near optimal to most sensible preferences, but it does have an impact on everything. How do we decide that a superintelligence "controls the universe", while my cat "doesn't"? The only difference is in what kind of the universe we have, which preference it is optimized for. Whatever you truly want, roughly means preferring some states of the universe to other states, and making the universe better for you means controlling it towards your preference. The better the universe, the more specifically its state is specified, the stronger the control. These concepts are just different aspects of the same phenomenon.
