The Second Life Vision: Digital Land, Dual-Layer Reality, and Ubiquitous Money — From Facebook Dialogues (2016) to a Unified Theory of Digital-Physical Economic Space

This paper reconstructs the author's vision — first articulated on Facebook in 2016 — of virtual worlds evolving beyond polygon-based rendering into a dual-layer reality. Using V=N/D theory (Value = Service / Friction), three convergent technologies are analyzed: polygon transcendence, dual-layer architecture, and ubiquitous money. When these three friction vectors simultaneously approach zero, digital land becomes real property, DOI coordinates become deeds, and the economy of physical and digital space unifies. Second Life is reinterpreted not as a failed product but as a proof of concept that preceded its enabling technologies. The paper formally records an intellectual priority claim that was voiced before the mainstream metaverse discourse, now permanently timestamped via DOI.
