It is able to dance freely, refreshing the knowledge of more people. The iteration and development of artificial intelligence has accelerated in recent years. Five or six years ago, the robot danced like with Parkinson. But now, they can dance with high flexibility and coordination, reaching the level of professional dancers. Now the robots can be engaged in physical works such as dancing, accounting and cooking. And they can use Gatling machine guns to commit an outrage. They can also be engaged in creation in cultural fields such as literature, art and music.
Behind all these, it is that human beings have used mathematical tools to sort out the data, rules, laws and regulations in all fields of society, and give them to a unemotional computer to run and generate corresponding digital rules, algorithms and operation models. People will also train it to accumulate data and model iteration continuously, so that it has self-developed artificial intelligence (AI), which already has the technical possibility to replace all professions of people.
