Importance: Core spine result: the dual benefit of CES curvature (superadditivity + model collapse protection from the same rho) is the central economic insight linking heterogeneity value to AI robustness.
Novelty: New theorem: model collapse protection and diversity premium controlled by the same parameter K. The three-way bridge (Grossman-Stiglitz / Shumailov / CES) is original.
Quality: Excellent exposition linking superadditivity and model collapse through the same K parameter. Clear LaTeX, strong quantitative bounds, good cross-links.
