differently to fluctuating circumstances around them. A machine is only capable of doing what has been programmed into it. A human is infinitely more resourceful, and not static in his methods.
A human brain will forever have more intelligence than can be "built" into a machine. No computer/database combo can ever compare to the human brain. The human brain is the ultimate super-computer, the likes of which may never be equaled by anything that humans can build "artificially".
There is not a single "super-computer" ever built that can compare to even the brain of a mouse.
