No, you've missed the point of the book (or haven't read it). It's about that some things become better in the presence of error/noise/damage/volatility. But not all things, some other, fragile things, become worse and worse as damage accumulates. And that there's no word for such a property, so he calls it "Antifragile". And then the book goes in great detail about lots and lots of examples (with the usual rambling).
