- Consider a chess-playing computer. In a trivial sense its next move in
- the game it is playing could be predicted from the laws of physics and
- a knowledge of its current state. In practice this would take grossly
- more computing power than is exercised by the device itself, by very
- many orders of magnitude. It would be much easier to predict it's next
- move from a listing of the code. And much easier again from a spec of
- the system and a knowledge of the laws of chess. But even here the
- unaided computational powers of a human being would be struggling to
- accomplish this prediction accurately in less than a few decades,
- although a good guess might be available in a few days.
-
- In other words, whether or not we do as the universe dictates is a
- rather airy theoretical distinction, since there is no way we can
- ever find out what the universe has dictated.
