The global Artificial intelligence （AI） is developing into depth. From the simple AI development trajectory，we may find that there are three development stages：human logic digitization，instrumentalization of logic ability and the intellectualization of objects. AI，with the automation of information processing at the core，has created an application pattern of “AI + media + scene.” The United States，China and the United Kingdom are the world leaders in AI research. Although China has edged into the first echelon，it still has not a small gap to bridge with the United States. At the same time，study shows that it is necessary to give full attention to such problems as the constraints in the process of applying AI extensively in communications.
