Also note that being able to pay rent to be able to predict something is still not the same as being able to control it. Kvothe might be able to know where every molecule of air is and be able to compute where they are going (ignoring for a moment issues of fundamental uncertainty due to quantum mechanical issues), but that doesn't mean one can figure out an action that will make the air do what one wants. To do that requires not just computing a single path of events but likely requires computing many paths and figuring out which one one wants. Similarly, the evil oracle has a much tougher job computationally than a regular oracle.

Conversely, in many cases, e.g., simple chaotic systems, it is easier to control something then to predict what will happen if you don't intervene.
