Abstract: Artificial intelligence plays an increasingly important role in social development， which may promote social development and human progress. Artificial intelligence has changed the human modes of production and ways of thinking， but as a disruptive technology it may bring some risks such as a widening gap between the rich and poor， and environmental pollution. The development of artificial intelligence may lead to such ethical problems as ethical responsibility conflict and social risk enlargement. Only by regulating the behaviors of intelligent machine designers and users， advocating the ethics of artificial intelligence professionals， and perfecting the laws and regulations on artificial intelligence， the security of using intelligent machines and systems can be effectively ensured so as to protect the fundamental interests of human beings and promote the healthy social development.

Key words: artificial intelligence, risk, ethics, Asilomar's AI Principles
