The Boundaries of Rationality: Game Theory, Probability, and the Philosophy of 'Doing Your Best' In human interactions and decision-making, whether it’s the micro-level of card games or the macro-level of societal operations, the essence often boils down to a “point-to-point” interactive field. Within such systems, there is no omniscient, all-powerful absolute certainty—no so-called “God logic.” The depth of thought and the limits of probability, under the premise of adhering to point-to-point objective rules, allow individuals to maximize their chances of winning through rational game strategies. However, due to the complexity and unpredictability of the system, no matter how perfect the strategy, the win rate can never reach an absolute 100%. This means that an individual’s “depth of thought” cannot equate to absolute control over the final outcome; it is merely a tool to improve the odds. In this field, what participants can pursue is not guaranteed victory but rather making “the best effort” under known conditions to achieve the greatest possible gain. From game theory to decentralized consensus, this acknowledgment of limited rationality and probabilistic boundaries was the core logical premise behind Satoshi Nakamoto’s design of Bitcoin (BTC). In a decentralized network, human “depth of thought” is physically quantified and equated to “the size of computational power.” The entire system does not rely on any centralized “God’s perspective” to maintain order but instead operates through probabilistic games driven by the computational power contributed by each node. As all participants strive to “do their best” for maximum gain, the system naturally achieves an unbreakable consensus. The Boundary Between Humans and Gods & The Sincerity of Existence “The best effort” is not just a survival and game strategy; it is also a philosophical dividing line that delineates the boundary between human capability and “God” (representing absolute truth and inevitability). Acknowledging the unattainability of absolute control is the greatest respect for the objective laws of the world. Meanwhile, exhausting all efforts within a limited probabilistic space is the most genuine sincerity humanity can display when facing impermanence and the unknown. Human dignity does not lie in attempting to become an omnipotent God but in pushing the limits of their computational power and thought within uncertain rules to achieve the utmost.
