The meaning of P=NP is that a utopian world can be constructed, and all solving problems can be computed by machines. This was also the theme of G ö del's letter to von Neumann in 1956. But at this point, it will also lead to the failure of all encryption algorithms and applications built on these asymmetric logics, such as Bitcoin. So we prefer to believe that P!=NP, and the meaning of P!=NP is that the world is created by asymmetric emergence and nonlinear adaptation. If P=NP, we can design any product using various computational logics. If P!=NP, we utilize the asymmetry between P and NP to design nonlinear adaptive complex products, such as Bitcoin designed by Satoshi Nakamoto.
