Antifragile summary: There are not just two states fragile and robust, there is a third one, antifragile. Robust things do not break like a fragile thing will but robust things don’t get stronger with time or random events. Antifragile systems do; they limit the exposure to downside and expose themselves to the upside if things go well. I found this book really engaging, novel and thought provoking. I would love to reread this and discuss with someone.
