I was reading a section of R. P. Feynman's book "Pleasure of Finding Things out" today. Let me summarize a beautiful thought he has pointed out with some addtition by myself. "The world is so wonderful in the sense that stars are made of the same atoms as the cows and as ourselfes, and as stones." Everything we do, feel or say can be understood in terms of what atoms can do, that is in terms of physical laws. So oneday the scientists can understand the atom's behavior in human body and can have the control on it. Artificial Intelligence is not mere a fictitious idea people are trying out.
