Brain and computer?

The difference between a brain and a computer can be expressed in a single word:complexity.
The large mammalian brain is the most complicated thing, for its size, known to us. The human brain weighs three pounds, but in that three pounds are ten billion neurons and a hundred billion smaller cells.These many billions of cells are interconnected in a vastly complicated network that we can't begin to unravel as yet.
Even the most complicated computer man has yet built can't compare in intricacy with the brain. Computer switches and components number in the thousands rather than in the billions. What's more, the computer switch is just an on-off device, whereas the brain cell is itself possessed of a trmendously complex structure.
Nowadays people like deal with anything through computer. I often use it to resolve problem. Meanwhile I like to think it by myself. The handwriting is full of emotion. What do you think about it?
