The Implications of Computational Equivalence

The principle of computational equivalence suggests that all computational processes, whether in nature, brains, or mathematics, are equivalent in their complexity. This principle implies that there is no systematic way to outperform these computation systems, highlighting the presence of computational irreducibility. Despite the vast complexity, certain pockets of computational predictability can be found, which align with significant scientific theories like general relativity and quantum mechanics.
