Abstract: Artificial Intelligence， a revolutionary technology that iterates constantly and drives new inventions， is profoundly changing the world and affecting the fate of mankind， deconstructing and reshaping production and life of modern people. In the era of intelligence， the development of mankind is in nature the development of humanization in the material world. Marx’s humanist thought provides the theoretical key to the questions of why artificial intelligence is possible and what it can be. Artificial intelligence has promoted the free and comprehensive development of mankind by satisfying people’s needs for good life， increasing people’s free time and promoting people’s return to work， which echoes the value return of the upgrading and iteration of science and technology. However， we need a comprehensive examination of the related problems derived from artificial intelligence: the ethical problem related to artificial intelligence， and problems of whether artificial intelligence will ”replace” human beings or result in the alienation of human beings.

Key words: Marx, humanistic thought, artificial intelligence, development of humanization, free development of mankind
