Taleb and the language of risk

Last night, I read about Nicholas Nassim Taleb on English Language and Usage StackExchange (EL&U). Professor Taleb wants to introduce a new word to the vocabulary of global financial collapse, antifragility:

So let us coin the appellation “antifragile” for anything that, on average, (i.e. in expectation) benefits from variability.

Consensus on EL&U was that this was a creative but unnecessary neologism. I echo the concerns of my EL&U comrades: Antifragility might cause confusion (maybe it is “anti-fragility”). There are many adequate, extant words that Taleb could use, however, antifragility is a term that will be uniquely associated with him.

I am not convinced that there are many entities that actually thrive due to uncertainty. A delta hedge that is long volatility is the only construct that I can think of off-hand. Perhaps that was what Taleb had in mind.
