Nassim Taleb's book Antifragility suffers badly from his writing style, but there are some important ideas here. One way to get the highlights is from his lecture as part of the book tour. His troublesome speaking style will prepare you for the writing style.
The core concept is the importance of a new concept in system design or description. Anti-fragility is the opposite of fragility. The conventional thinking is that robustness or resilience are the opposite of fragility. But, fragility means damaged by external shocks. The opposite is a system that is improved by external shocks. So an anti-fragile device would be labelled, "Please handle roughly". Robustness and resilience are forms of lower fragility, not anti-fragility.
Anti-fragile systems occur in nature in many ways. Muscle and bone tissue need external shocks. A complete absence of loads or shocks leads to wasting away. It's a major problem for long term space dwellers. You strengthen muscle and bone by pushing them close to their limits at appropriate intervals. The muscle and bone respond by growing stronger. That's anti-fragility. There are limits to how hard you can shock an anti-fragile system, but anti-fragile systems are superior to robust or resilient systems.
The book is many snippets and comments around that theme. It's not well organized for taking the concept to the next level of discussing how to create anti-fragile systems. There is a lot there, but it suffers from Nassim's presentation style. As one reviewer put it, "He's a notorious jerk."
At least he's also introduced me to the word flâneur. That's a fine goal for the enjoyable life.
