The many worlds theory is incredibly inefficient from a computational complexity perspective. The theory that human brains perform arithmetic at less than one

The many worlds theory is incredibly inefficient from a computational complexity perspective. The theory that human brains perform arithmetic at less than one FLOPS while dissipating 20 watts is incredibly inefficient from a computational complexity perspective. The theory that sugar dissolves into tea by interactions of more than 10^23 sub-nanometer structures is incredibly inefficient from a computational complexity perspective...
