Well so what if they can predict the future better? That's certainly one possible advantage of AI, but it's far from the only one. My greatest fear/hope of AI is that it will be able to design technology much better than humans.
The way I think of it, designing technology is a special case of prediction. E.g. to design a steam engine, you need to be able to predict how steam behaves in different conditions and whether, given some candidate design, the pressure from the steam will be transformed into useful work or not.
You can design things based on a priori prediction, but you don't have to in many cases...you can also use trial and error instead.
