<p> My thesis explores the idea that Buckminster Fuller&rsquo;s World Game is really a formal calculus capable of representing world-scale sustainability problem-solving according to the fundamental principles of a (blockchain) <u> database</u> + (Fuller projection) <u>map</u> + (machine learning) <u>simulation</u> in the form of a <u>game </u>. 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&rsquo;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 &ldquo;game&rdquo; is sufficient for solving the problem of &ldquo;making the world work for 100% of humanity in the shortest possible time through spontaneous cooperation without ecological offense or the disadvantage of anyone&rdquo;&mdash;the objective of World Game. If this hypothesis of sufficiency is true, that means World Game&rsquo;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.</p><p>
