The problem with Taleb is that he is insecure enough that he has to not only advocate for a position, but then go on to spend most of his time and effort denouncing everyone else in the world as "sub-imbeciles". The truth is that literally no-one who seriously studies options assumes a normal distribution in the returns on the underlying and they haven't in my lifetime. To the point that I distinctly remember my finance 101 professor disclaiming nearly on day 1 that while we were going to use a normal distribution for teaching purposes, we all needed to remember that returns don't actually follow a normal distribution in real life. Do a google scholar search for "distribution of stock returns" and the first of literally 2 million papers was one written in 1972 discussing how returns are more "fat tailed" than the normal distribution, so this isn't a new concept. More recent work goes into excruciating detail on the pluses and minuses of various distributions.
We actually don't live in the fantasy universe that Taleb has built around himself where there's a clear, obvious answer that only he "gets" and the rest of the world studying and working in the subject are morons. Don't let him fool you into joining his little delusion. The truth is there's a lot of smart people doing a lot of good work in the area, the world's a nuanced place without a lot of black and white or right and wrong answers, and Taleb is an insufferable narcissist.
