Then, Taleb is a jerk when someone tries to pin him on one of his wild exaggerations. Even as a quant Taleb was prone to smushing over details to push a narrative. In the 90s already Derman was enabling Taleb into claiming the Black-Scholes formula was an interpolation algorithm already known to option traders and served basically to justify using the risk-free rate as a drift (price trend) parameter in accordance to the "economics establishment". But (as noted by more than one response in the literature) making a different assumption on the drift (or even the distribution) -- i.e. leaving the "Black-Scholes world" and merely interpolating two world-states -- you're left with calibrating a stochastic discount rate that gives put-call parity. But hey, not that technicalities should get in the way of a good story!
