The Self-Evolution and Multiplication Model of the Thought OS — Thought OS Series Phase 3: Summary

This paper serves as the Phase 3 summary of the “Thought OS Series,” systematizing how the Thought OS evolves recursively, multiplies through interference and resonance with others, and expands into collective and institutional forms. Phase 3 presented: (1) the self-recursive structure (FQ → Question → Structural Pressure → Mindflight → SQ → Deepened FQ), (2) the Thought Immunity System (Interference, Resonance, Rejection, Differentiation + Three-layer Defense), (3) the conditions for a Collective OS (FQ Sharing, Structural Pressure Resonance, Leap Synchronization, and the Five Role Model), and (4) Institutional OS formation (a three-stage model in which social systems internalize and autonomously operate thought). Furthermore, through the Irreversible Four-Stage Subject Shift Model, it demonstrates how the “subject” of thought moves from “I” to “Between,” “We,” and “Institution” in an irreversible evolution. This paper also clarifies the connection from the “Third Intelligence Revolution” (Structure) to the “Fourth Intelligence Revolution” (OS-ization), incorporating human-AI co-evolution and a fully self-referential structure, and envisions a future in which thought is designed, operated, and inherited as an OS.
