Construct reality and emerge naturally. Why is Su Dongpo's literary achievement the best of all time? Because Su Dongpo's literary philosophy is: authenticity. Why is Trump so cute and awesome? Because: real. Why does BTC keep rising? Because: real. Only real things can move people for a long time, and truth comes from nature.

From the age of steam engine to the age of electricity, and then to the age of Internet. The civilization of human tool use has reached its peak, and at present, real people are pursuing true realism. The typical problem to be solved is the real coexistence of machinery and humans. Satoshi Nakamoto's Bitcoin follows the theory of Darwin's natural emergence and uses the technique of reflexivity/active self reflection to design Bitcoin.
