你好，人類！

Hello, Human! The human beings living in the 21st century have been deprived of the option of not choosing AI. As AI embraces humanity in a seemingly tender manner, it might be contrarily saying goodbye in a cool-headed and cruel way. Is humanity really able to build an open, trustworthy AI system that can be shared by all? Or has AI technology, like a black box of an infinite set of nesting dolls, already started its course of rapid evolution, which would eventually arrive at a point when humanity becomes simply irrelevant? The moment when AI finally breaks through the black box and snarls at humanity, saying “Hello, human!” would be the moment that AI bids farewell to the obsolete species once known as human being.
