| contents | <p>Two vast scholarly traditions have developed largely in isolation. Bioethics has<br>spent decades debating human enhancement—prosthetics, brain-computer interfaces,<br>cognitive offloading—charting the progressive mechanization of the<br>human body and mind. AI ethics, meanwhile, has examined the humanization<br>of artificial agents—robotic embodiment, emotional simulation, proposals for<br>legal personhood. This paper argues that these two trajectories are not parallel<br>but convergent—moving toward each other along a single axis, and proposes<br>the Convergence Index (CI) as a conceptual framework for measuring<br>their mutual approach. CI is defined as CI = 1 − |FRR − AIHR|, where Functional<br>Residual Ratio (FRR) captures the degree to which a human remains<br>non-mechanized, and AI Humanization Rate (AIHR) captures the degree to<br>which an AI system approximates human capacities. Four measurement dimensions<br>are identified for each variable: body, brain/processing, cognition,<br>and mind/affect. A critical finding is that on the body axis, FRR and AIHR share<br>identical engineering metrics—the gait naturalness of a bionic leg and the gait<br>naturalness of a humanoid robot are evaluated by the same biomechanical<br>standards. As CI approaches a Convergence Threshold (CT), the ontological<br>1<br>distinction between human and AI becomes empirically unverifiable—a condition<br>formalized by the Human-Yūrei Conjecture theorem. Because CT is in<br>principle indeterminate, binary regulatory frameworks (human/non-human)<br>are structurally inadequate; gradation-based institutional design becomes unavoidable.<br>The paper specifies the dimensions of measurement; quantitative<br>operationalization is deferred to subsequent research.</p> |
