What is AI? /briefly describe the links between learning, reasoning and storage?

Ai's general personal understanding is that all human wisdom manifests itself in the behavior of new technologies, such as robots. The use of technology "machines" to replace human activities. The specific goals are divided into the following three: theoretical analysis of the effective interpretation of intelligent behavior, interpretation of human intelligence, construction of intelligent artifacts. A machine without blood, without a body, can perceive things around him as human beings, and can have the ability to remember and think, to find a suitable treatment, to learn new ways to do puzzles, to act as human beings (scientists and technicians to create the same shell as human beings), to talk, to look, to pose, and so on. In short, it is to make a "machine" in harmony with mankind.
