They just aren't much use for working things out as they happen.
If the physicists a hundred years ago were right, you could take the position of all the particles in, say, an antelope, work out the wave-function for it, and work out what it would go next.
Except you'd need more computational power than you could ever get, and you still haven't modelled the wave-functions of the grass it is eating, or the lioness hiding behind that rock, which are interacting with and changing what happens to the antelope every moment.
So we make up little stories about what they are doing and why, that will never get down to the level where things are really worked out, but are rough guides to the future. "the antelope has spotted the lioness, and he will run... NOW!"
Once humans got good at stories like that, they then tried out things like mercy, and altruism, and sometimes even justice.
Complicated concepts produced by simple modules re-purposed and rewired in unexpected ways.
Admittedly, Milton Keynes has never been sufficiently explained. Probably proof of a malign intelligence (or 1960's architect) at work. |
