Even without shortcuts, or approximations "good enough" not to imply
any perceivable behavioural modifications, an organic brain is a
relatively small system with a very finite number of states. Even very
big brains have some 10^20 or something molecules, and that of. say,
fruitflies orders of magnitude fewer...
