Actually, Kasparov is doing somewhere around 200 trillion operations in his head every moment, not merely 100 billion. His brain isn't single-purpose, though, as Deep Blue is. The brain, as Montague points out, does all sorts of things consciously and subconsciously that Deep Blue has no chance of doing with only 100 billion operations/second. It's much more omni-purpose than Deep Blue's processors. And, while it's interesting that Deep Blue can be produced with relatively low energy cost, it's interesting in the way a fly can be produced with low cost compared to a human. The fly is designed for a very specific type of life, and it does a nice job with it. But a fly is not nearly as adaptable as a human, and neither, ultimately, is Deep Blue. Our long setup period allows us to do some incredible tasks that we are still decades from understanding well.
