Understanding nature is something a lot of people talk about, but it's not obvious to me that it is possible. As in, not possible at all, at exactly the same level as what you are referring to.
Put simply: there are a lot more possible states in a giant universe than in an individual ape's brain, or even in a collective system made up of many such apes. Wouldn't information theory tell us that we can never represent the larger system inside the smaller one? Or if we do represent it, it has to be as a model that is necessarily incomplete?
