After entering the 2 1 century, the plagues, famines and wars that once threatened the survival and development of mankind for a long time have all been conquered. Homo sapiens is faced with a new topic to be discussed: eternal life, happiness and becoming a "sacred" human being. In the process of solving these new problems, the development of science and technology will subvert many of our "common sense" that does not need proof at present. For example, the free will advocated by humanism will face severe challenges, and machines will replace human beings to make wiser choices.

More importantly, when the development of science and technology represented by big data and artificial intelligence becomes more and more mature, human beings will face the biggest change from evolution to homo sapiens, most people will become "worthless groups", and only a few people can evolve into "gods" with changed characteristics.

In the future, mankind will face three major problems: biology itself is an algorithm, and life is a process of constantly processing data; Separation of consciousness and intelligence; The external environment with big data accumulation will know yourself better than yourself. How to treat these three problems and how to take countermeasures will directly affect the future development of mankind.
