Artificial intelligence is a branch of computer science, which tries to understand the nature of intelligence and produce a new intelligent machine that can respond in a way similar to human intelligence. The research in this field includes robot, language recognition, image recognition, natural language processing and expert system. Since the birth of artificial intelligence, the theory and technology are becoming more and more mature, and the application fields are expanding. It is conceivable that the technological products brought by artificial intelligence in the future will be the "containers" of human wisdom. Artificial intelligence can simulate the information process of human consciousness and thinking. Artificial intelligence is not human intelligence, but it can think like human beings, or it may exceed human intelligence. Artificial intelligence is a challenging science, and people engaged in this work must understand computer knowledge, psychology and philosophy. Artificial intelligence is a very extensive science, which is composed of different fields, such as machine learning and computer vision. Generally speaking, one of the main goals of artificial intelligence research is to enable machines to be competent for some complex tasks that usually require human intelligence. With the development of artificial intelligence and intelligent robots, it has to be discussed that artificial intelligence itself is an advanced research, which requires modern scientific research with a future vision, so it is likely to touch the ethical bottom line. As a sensitive issue that may be involved in scientific research, we should prevent possible conflicts as soon as possible, instead of trying to solve them when contradictions cannot be solved.
