> Standard deviation, STD, should be left to mathematicians, physicists and mathematical statisticians deriving limit theorems
>There is no scientific reason to use it in statistical investigations in the age of the computer, as it does more harm than good
He is saying it's not useful for real world things and people are just confused. What you wrote is reasonable view. What Taleb writes isn't.
