There are essential differences between artificial intelligence and human thinking. Machines themselves can't think, let alone be smarter than people.
Artificial intelligence and human consciousness are fundamentally different in origin and material basis. Human consciousness is a highly organized substance-the function and attribute of the brain (its complexity is far from being understood today), and the basis of artificial intelligence is a mechanical material system composed of electronic components. So people's thinking process and computer's "thinking" process belong to two completely different sports processes. Although the movement of consciousness is accompanied by the physical and chemical changes of the brain, it also has more complicated physiological and psychological processes, and the "thinking" of the machine is only a pure material process. When it is thinking, there is no subjective psychological experience at all. When thinking, people are subjectively aware of their own thinking, as well as the content and process of thinking, while the "thinking" of computers has no subjective self-awareness at all. One is the psychological process that takes place inside living organisms, and the other is the material movement of rigid machinery.
Human brain and consciousness are not only the product of long-term biological evolution, but also the product of social movement. Consciousness is always the consciousness of society, and computers are just machines made by people. They can't live a social life like people and participate in extensive social practice, which is irreplaceable.
