The brain and the computer
Recent studies in the computer industry make scientists predict that the difference between humans and the computers will disappear by the year 2050.
To understand thesignificance of this prediction, we need to compare the human brain with existing computers.
The human brain typically weighs about 1 ½ kilos.
It consumes electrical energy at the rate of 25 wattsand occupies a volume of 1/10 of a cubic foot. Within this volume, the brain houses between 10 billion and 100 billion pieces of information.
The most powerful computers today have memories that holdonly a few million items of immediately accessible information. These machines consume 100,000 watts of electrical power and occupy hundreds of cubic feet of space. Their capacity is far less thanthat of the brain.
The superiority of the brain is even more striking. Every brain cell is directly connected to many other cells. This makes it possible for those cells to communicate on asubconscious level, which results in intuition, insight, perception and creative inspiracion. The computer, in contrast, has no thinking capacity and no connections elsewhere.
Compared to the human brain, themost powerful computer today is hopelessly inadequate.
