Hey! You've been complaining about the other side's simplistic analyses, but here you're doing exactly the same thing. Deep Blue included special purpose hardware for playing chess, as well as dozens of general purpose CPUs. And you're claiming it's looking at 25 million times as many positions per second. Yet, Deep Blue lost to Kasparov, and Deeper Blue only just managed to eke out a victory. So, the 25 million number is crap, isn't it? It appears the human and the machine are roughly at parity, in terms of chess playing ability. And Kasparov is a general-purpose machine, capable of doing things that Deep Blue can't, like ride a bike.

One lone human has *way* more processing power than today's computers. This is a sufficient explanation of their difference in cognitive ability.
