I heard quite a bit abt Taleb but only read Fooled by randomness before and wasn't overly enthusiastic, although more because of style than substance.
Antifragile could have been (much) shorter, and the issue is IMO less in the money spent to buy the book than the time to read it. It's a little boring in Taleb's narcissistic ways to lecture on abt everything, even spending at least over a dozen pages on nutrition and weight lifting, and I was familiar with much of the book as he picks a lot from his own writings, as well as kahneman and Mandelbrot, but the antifragility thesis is still quite interesting (but not as new as the term he might have coined), and he comes up with plenty of historical references, many I wasn't familiar with.
