Your sarcasm not withstanding, it's possible that the part of human brain
required to play chess is the size of a walnut. Certainly, animals with a brain
smaller than that size are computationally much more sophisticated than Deep
blue. What the pentagon wouldn't pay for a smart weapon with intelligence and
perceptual abilities of an eagle.
