The human brain is not organized anything like a modern computer. The human memory is not organized like a computer database. It is more like an incredible number of hyperlinks. There is no index in the computer sense of the term. A human brain can not be viewed as having software and hardware. It is like a computer which is constantly being rewired. A human brain does not store data, it rewires itself. Furthermore, we know that the stored data relating to something like a Rsoe bush is scattered around the brain in a strange fashion. The outline of the green petals is stored with other outline dat, while the green & red colors are stored someplace else. The words relating to the rose bush and all its characteristics are simlarly scattered. The memory of how to say those words is stored separately. If you read about the functioning of people with various types of brain injuries, you might be amazed. For example, some people can recognize colors visually, but cannot say the words red, blue, green, et cetera. Considering the apparent speed of individual components, it is very fast at certain operations. A computer usually takes longer to decide that a searched for item is not there. A human can often say I never saw that guy/girl before almost immediately, while it might take a while to remember somebody you knew many years ago. This suggests some fundamental difference in organization. We have very little knowledge of how to build a computer system which would function like a human brain, and there is eveidence that se cannot do it with raw processing power and huge memory resources. The computers who beat chess experts can hardly do anthing else.
