The problem with genetic algorithm's, as I understand Stuar Kaufmann, is that
while "weeding out redundancies" the fitness space becomes more spiky and
therefore harder to search. The "optimal" solution decays into simple random
guessing in in infinite search space. So, sloppiness and waste is Good - it
helps by creating an area of the fitness space where the "creature" can "move"
i.e. adopt/evolve.
