My thesis explores the idea that Buckminster Fuller’s World Game is really a formal calculus capable of representing world-scale sustainability problem-solving according to the fundamental principles of a (blockchain) database + (Fuller projection) map + (machine learning) simulation in the form of a game. These computational media comprise an operational formalism which embraces all effective procedures for world-scale problem-solving. If this hypothesis is true, then that would mean World Game’s comprehensive use of the aforementioned fundamental principles are necessary for a sustainable Earth-scale civilization. Furthermore, the protocol for solution formation in the form of World Game “game” is sufficient for solving the problem of “making the world work for 100% of humanity in the shortest possible time through spontaneous cooperation without ecological offense or the disadvantage of anyone” — the objective of World Game. If this hypothesis of sufficiency is true, that means World Game’s principles are in effect synonymous with the process of making the world work. In plain English, a problem-solving engine like World Game is necessary for the survival of humanity, period.
