Category theory is a type of mathematics that challenges us to rethink fundamental ideas about numbers, as experimental outcomes. Essential to quantum field theory, its role in gravity remains elusive. Such nonsense is introduced under the assumptions that (i) unification is a valid goal for physics and (ii) relativistic causality holds for local observables. Is fermionic spin analogous to Boolean truth? If so, we should remember that whatever is divided is also non separable, and this ultimate reality cares nought for all our vanity.
