This concept references a system or idea that learns and improves from disturbances it encounters.
Antifragile is a term by Nassim Nicholas Taleb to describe things that improve when perturbed. "Some things benefit from shocks; they thrive and grow when exposed to volatility, randomness, disorder, and stressors and love adventure, risk, and uncertainty. Yet, in spite of the ubiquity of the phenomenon, there is no word for the exact opposite of fragile.
Antifragility is beyond resilience or robustness. The resilient resists shocks and stays the same; the antifragile gets better". Antifragility is a feature of thrivability, and is part of what marks its distance from “sustainability” or “resilience”. Thrivability is not a call to return to a prior state, but an embodiment of the willingness to learn from the disturbances we encounter.
