I don't get this explanation. Sure, a process can tend toward a certain result, without having an explicit representation of that result. But such tendencies often seem to be fragile. For example, a car engine homeostatically tends toward a certain idle speed. But take out one or all spark plugs, and the previously stable performance evaporates. Goals-as-we-know-them, by contrast, tend to be very robust. When a human being loses a leg, they will obtain a synthetic one, or use a wheelchair. That kind of robustness is part of what makes a very powerful agent scary, because it is intimately related to the agent's seeing many things as potential resources to use toward its ends.
