What does antifragility mean?

Antifragility is a concept originally coined by Nassim Taleb, and its definition is deceptively simple: it means "the opposite of fragility." In other words, antifragile gets stronger when exposed to volatility, randomness, disorder, and stressors. You are an antifragile system if you become stronger when everything around you is getting chaotic.

Antifragility has been used in several industries. The term "antifragile" was first applied to software development by Google's director of engineering, Ray Kurzweil. He dubbed the technique "antifragile programming," describing it as an approach in which programmers embrace uncertainty and chaos by building systems that thrive on change with no surprises (my emphasis).

The antifragility concept has also been applied to marketing, finance, architecture, engineering, healthcare policy, governance, genetics, and biology.
