Man's system of values is formed during the course of actuating desires and needs, receiving education, experiencing life and practicing social activities. The value system is unconscious in mind and its function is to engender a drive to actuate man's physiological and psychological balance to dominate man's judgements and choices, namely attitude and orientation of behaviors. The computer does not have any desires, needs, emotions and wills as a subject, and it does not have the drive for spontaneous mental balance, either. In order to endow the computer with intelligence, we need to guide its orientation of intelligence, and it should be agreeable to the logic of man's value system. So we need to set up a system of values and a spontaneous function of dynamic psychological balancing for the computer and make it subjectivized. This way of intelligentizing the computer depends on the drive originated extrinsically. The feature is that the process is accordant with the developing mode of human intelligence; the interactions with outside primarily orient human being; the modes of input and output of information are compatible with human sense organs, and man believes that he is able to control the orientation of the values of the cyberbrain. We can find the embryo of this intelligentization in many of current computer programs, but it can not go farther on this way. Whether the cyberbrain will alter the acquired values or not is another thing to argue.
The other way of making artificial intelligence is to endow the computer with instinct to form its own values spontaneously. This instinct is almost non-human-oriented and the value system that it forms is entirely natural, and perhaps unfathomable to human being. The risk of such intelligence is that it grows away from human being and forms the values deviated from that of human being or even goes antihuman. The value system of human being is centered on human itself and established on the basis that human interest is the highest of all, but the cyberbrain may regard the most important thing as to keep a sort of nature balance.
Human never allows itself to be dominated by foreign wills as chips or jetons. Most people deem that the purpose of creating the artificial cyberbrain is to serve human and let it follow the orders by human. They are unconsciously certain that the property of the cyberbrain is of still a tool and its use is nothing more than to help people work out, explore and discover rules and laws and adopt these, but this will most probably be their own wishes only.
