Query: Quite frustrating

I liked Taleb's book, but I also found it quite frustrating to read. Whenever I looked closely at a definition or an equation, it was more likely to be incorrect than not. Further, I'm afraid I also found the prose at times overbearing: statements to the effect that 'People with PhD degrees are of a higher mental calibre than those without', and similars, are really out of place. I think the book should have been more rigourously edited by the publisher. Authored by a practitioner with interest in mathematical analysis, it could have been an extremely useful book.
