The Meta World Series: Eight Coordinates of the Dual-Layer Civilization — Digital Land, Resonance Economy, and the Coming Second World

This paper presents the master framework of an eight-part series on the emerging dual-layer civilization — a world in which physical and digital reality coexist simultaneously through wearable spatial computing interfaces. The series originates from Facebook dialogues conducted by the author in 2016, reconstructed through AI-assisted dialogue in 2026, and permanently timestamped via DOI. Using V=N/D (Value = Service / Friction) as the unifying equation, the series maps eight structural coordinates of the Meta World: (1) The Second Life Vision, (2) The Dual-Layer Human, (3) The Infinite Estate, (4) The Observer's Archive, (5) The Secret BAR, (6) DOI Credit Score, (7) AI-Dialogue Startup, (8) The Resonance BAR. Together, these eight coordinates constitute a civilizational design document for the world that is coming — authored from Fukui, Japan, beginning 2026.
