Ontological Constraints and Technological Paradigm Reconstruction of Intelligent Systems under Dao-Er: A Techno-Philosophical Foundation of the "One-Two-Three" Framework

Contemporary intelligent systems (artificial intelligence, autonomous driving, quantum computing) are generally trapped in ontological dilemmas of “optimal yet fragile,” “inadequate security,” and “isolation not feasible.” Based on Dao-Er philosophy, this paper proposes a unified ontological structure of “One (structural invariance)—Two (dyadic coupling)—Three (dynamic equilibrium)” to provide a priori constraints for intelligent technology. It demonstrates that absolute isolation is ontologically impossible, extreme optimization necessarily leads to instability, and security can only be an a priori constraint rather than an add-on feature. The Dao-Er framework reveals the essential laws of technical systems: structural invariance is the bottom line of existence, dyadic coupling is the only way of operation, and dynamic equilibrium is the necessary form of sustainability.
