Bach's *The Art of Fugue* inspired von Neumann to create the stored-program architecture for computers. A standardized design can be independent of any subject (instrument/computer medium). And the self-growing introspection model of Bitcoin blocks is exactly the same as Escher's self-referential style in his drawings. Complete decentralization and freedom, independent of any third party—posing its own questions, answering its own questions, completing its own verification, and then entering the next cycle of self-referential structure.
