Sigh. A mathematical model gets invalidated when its assumptions are no longer true. It does not involve some demigod declaring it invalid ex cathedra. No account was taken of the devaluation in the model. How, then, can you be certain it has not been invalidated? All you know is that it has not formally been withdrawn. |
