The value of automatic machine system is the compound value of the organic unity of the practical value form and the theoretical value form of sublating the logical power of capital that human (labor) sublates to the capitalist production mode, and it is manifested as the historical dialectical development law of labor (value) -- capital (surplus value) -- labor (value). The value evaluation of automatic machine system mainly includes human learning value and thinking value. Marx's thought on the value of automatic machine system adheres to the distinct problem-oriented consciousness, which is based on the development of nature, society and human thinking system, and responds to the requirements of the new era of intelligent system. It should be a prospective research topic in the field of value philosophy.
