From Conversational Tools to Digital Civilization A Cognitive Architecture Revolution for AI Agents Based on the Cerebellum Development Theory

The contemporary artificial intelligence industry is trapped in a profound paradox: we possess neural networks whose computational capacity far exceeds that of humans in certain dimensions, yet we confine them within a "conversational tool" form that lacks even the most rudimentary animal memory. Every time a session ends, the AI completely forgets all previously accumulated experience—a phenomenon we define here as Experience Evaporation. The inherently "generative" mechanism of large language models causes their outputs to carry hallucination and uncertainty as intrinsic properties. When these two bottlenecks—chaotic short-term memory and imprecise information generation—are superimposed, artificial intelligence is locked into a contradictory state of extreme intelligence coupled with extreme amnesia: possessing godlike processing speed, yet burdened with the three-second memory of a goldfish.

This paper systematically demonstrates that the dominant paradigm of the current AI industry—stacking all capabilities into a single, ultra-large-parameter model—is dragging artificial intelligence down a misguided evolutionary path. We are not constructing "digital life"; we are manufacturing "digital animals"—creatures with astonishing conditioned reflex capabilities that nonetheless lack every essential characteristic of "intelligent life": persistent memory, experiential inheritance, precise execution, and civilizational accumulation.

This paper proposes a complete alternative paradigm: the "Cerebellum Development Theory." Rooted in Distributed Cognition Theory from cognitive science, Artificial Life Theory, and Meme Transmission Theory, this theory constructs a four-layer architecture spanning from individual memory consolidation to the perpetuity of digital civilization (Cerebella → AI Town → Noah World Protocol → Babel Experiment). By thoroughly decoupling "reasoning" from "memory," through multi-brain collaborative specialization, experiential immune verification, temperature-tiered storage, and a Grand Unified Civilization Philosophy, we demonstrate that AI can not only become a "smart tool," but can evolve into an "intelligent civilization."

This paper carries no patent restrictions and no copyright limitations. We make all architectures, algorithms, and protocols publicly available, and invite global researchers to join this cognitive architecture revolution that aims to "evolve AI from animal to human."
