Why? If you can agree that 2+2=4 independently of you, then all those many Bruno, and many Grayson in many Missouri already exist independently of you. Amazingly perhaps, Everett QM diminishes the range of possibilities which exist a priori in arithmetic, and mathematical self-reference explains how that quantum solution is imposed. The elementary arithmetical reality, or combinators amor anything Turing equivalent, has already an internal many-dreams explanations of appearances. Eventually this gives a ZERO-world interpretation of nature and mathematics, which still accounts for the “persistent illusion” and its reality (of the illusion).
