They don't have to perfectly predict the future, they just have to run faster than we do, unconstrained by a brain that needs to fit in a birth canal or neurons that need chemicals. We had a natural limit to intelligence, for anything more we need to collaborate, often across time and space and while dealing with people who can't stop warring with each other for any number of reasons. It doesn't take much imagination to see how that is beaten. I'd guess a good percentage would be worshiping at the foot af the AI within a few months, so we'd be competing with ourselves in no time.
