Antifragile (edited EN title)

Taleb splits the world into three kinds: fragile, robust, and antifragile.

Fragile things fear volatility, robust things survive it, but antifragile things benefit from it.

That is a big lesson for quant work: a good strategy should not merely "survive on historical data" — it should be structured to profit from uncertainty.

Three ideas that stuck

1. Volatility is not the enemy. Moderate stress makes a system stronger — markets, muscles, and minds alike.
2. Do not predict; prepare. Instead of guessing tops and bottoms, build a portfolio that will not die in any scenario.
3. The barbell strategy. Extremely conservative plus extremely aggressive, rather than a bland middle.

The biggest takeaway: shift attention from "predicting the future" to "benefiting from uncertainty".
