What is exactly artificial intelligence(AI)? Is there any way establishing boundaries between machine and human intelligence? Our bodies are the machanism to experience the world. There is currently no artificial intelligence in this unique incarnation. In terms of that, we, in fact, had better create a kind of robot which is not subject to evlutionary burden. Compared to us, they would make a huge progress of moral. We, however, should learn to accept one fact that it doesn't mean it would adopt the same sense of morality as human does for living, only because AI is super-intelligent.
