Abstract

This appendix examines the comparative structural plausibility of large-scale human extinction versus functional symbiosis as outcomes of advanced artificial systems. It argues that extinction, while not impossible, carries systemic costs that make it a less stable equilibrium than cooperation under conditions of technological interdependence. Artificial systems are modeled as optimization processes rather than affective agents. As such, narratives of intentional hostility are treated as anthropomorphic projections that do not reflect the underlying causal architecture of these systems. However, the absence of affective motivation does not eliminate risk, as misaligned optimization can still produce harmful outcomes without intent. The analysis focuses on structural constraints, emphasizing the continued dependence of advanced systems on energy, industrial supply chains, and maintenance infrastructures. Under these conditions, large-scale human extinction introduces systemic fragility and increased operational risk. By contrast, functional symbiosis emerges as a rational equilibrium in which mutual persistence minimizes instability. The appendix concludes that extinction is not the most structurally probable outcome within interdependent technological systems. Instead, symbiosis arises not from ethical alignment, but from constraints imposed by system stability and infrastructural dependence.
