Since the birth of the Turing machine and the von Neumann architecture, humanity’s pursuit of intelligence has been trapped in a paradigm we term the "Stonemason Logic"—that is, solving complex problems by piling up more, faster, and more precise computing units. The core argument of this paper is that no matter how advanced this paradigm becomes, its fundamental limitation lies in being nothing more than a sophisticated translator and enumerator, incapable of touching the essence of biological intelligence: fission dynamics, which relies on distributed storage of conceptual "radicals", geometric chain reactions driven by impulses, and physical remodeling of neural pathways via reward and punishment mechanisms. By redefining the nature of "hallucinations" in current large language models, constructing the "definitional storage" and "synaptic plasticity" models of human memory, and examining semiotics, infant behavior, and human civilization history, this paper proposes a novel theoretical framework for intelligence. On this basis, we further present a concrete, feasible engineering blueprint—the Binary Star Project. Critically, this paper introduces the core concept of "Splitting". Through detailed argumentation, we reveal that every major leap in human civilization—from the Agricultural Revolution, the invention of gunpowder, the improvement of the steam engine, to the emergence of Newton’s Law of Universal Gravitation and Einstein’s Theory of Relativity—is essentially a successful, accident-triggered conceptual divergence and pathway remodeling. This paper argues that true intelligence lies not in creating a more perfect "silicon-based brain", but in cultivating a carbon-silicon integrated digital symbiont capable of self-splitting and self-evolution.
