Security is the real risk here, because the claim that a proof 'creates' the equivalence between fixed-point sensitivities and KKT is a conceptual slip. A proof only reveals or formalizes an equivalence that, if it exists, is independent of its demonstration. We must size the bullish potential of systems, not turn a blind eye to their intrinsic limitations; volatility is a catalyst. For example, unexpected changes in the liquidity conditions of the Italian bond market could render this 'equivalence' irrelevant, despite its proof.
