IBM say, "Today's computers are little better than calculators; ruled by the von Neumann architecture for over half a century, they use storage structures and programmable memory that scientists are endlessly aiming to improve. However, the human brain - the world's most sophisticated computer - can perform complex tasks rapidly and accurately using the same amount of energy as a 20 watt light bulb and consuming as much space as a 2 liter bottle of soda. Researchers at IBM and collaborating universities are working to build cognitive systems that can learn and perform complex tasks such as action, recognition and perception, while rivaling the low energy and power consumption of the human brain."
