How to understand the narrative of GEB @ BitAgere's complex adaptive system for perceiving reality? -Perceive reality? The abstract model of the oracle Turing machine is used to solve decidable problems in non computable situations (i.e., relative computable problems in asymmetric modes), and the landing object of the oracle Turing machine that solves decidable problems can be called a perceptron. The object that is analogous to solving computable problems with Turing machines is called a computer. -2 complex adaptive systems? Complex adaptive systems, abbreviated as CAS, refer to the complexity of how individuals emerge by solving decentralized arbitration problems. The dual spending problem of Bitcoin is an example of the decentralized arbitration problem (also known as the decentralized trust problem), and the method to solve the decentralized arbitration problem can be based on Turing's 1939 paper, which proposed an ordinal based super poor iteration layer by layer to increase the reliability of trust, thus using the iterative process of the algorithm to solve the decentralized arbitration problem.
