I see what you are saying, but the whole point behind anti-fragility is that change is for good, not bad. By default, in fragile things, change is bad. But in antifragile things, that change is harnessed for good.

Hm. The best way to clearly demarcate that would probably to move the word "bad" from describing the word "change", and put it as part of the first sentence.

Things sometimes break, and that is a bad thing that you do not want happening. It happens when outside forces cause changes to it and to the world it acts in. ...
