"Though your beginning was small, Yet your latter end would increase abundantly." -- Job 8:7 (NKJV)
Something that's antifragile isn't just the opposite of something that breaks easily, it's actually something that benefits from buffeting. The book's choice of its title demonstrates its biggest weakness: It takes a pretty simple concept and mostly defines it in negative terms. Antifragile would have been much more useful if it had focused on identifying many examples of such instances and discussed how to think about interacting most effectively as an individual and an organization in such environments.
Professor Taleb comes across as someone who greatly feels that he's been treated unfairly by critics and the uninformed. Much of the book expresses such experiences and his understandably annoyed reactions to them. In that sense, there's a sense of reading a memoir in places.
I found that the concept made sense to me and provides a useful way to express circumstances and relationships that offer great potential ... but for which I previously had no terminology to describe. Seldom have I found a book that adds to my thinking as usefully in terms of both the concept and the ways to apply it. I felt as if a major part of my brain's map of the world was sketched in for the first time.
I was almost as greatly indebted to the many explanations of why optimizations are bad, due to increasing fragility ... so that when variability inevitably occurs the negative consequences will be increased.
I also appreciated the careful way that resiliency and antifragility were distinguished from one another.
Very nice ... but please, Professor Taleb, make your next book less of a diatribe against those who don't understand you for those of us who like your ideas.
