[CHALLENGE] Is resilience engineering conflating resilience with robustness?

I challenge the claim that "resilience is not the opposite of fragility." This statement, while poetic, contradicts the most influential framework for understanding resilience in the 21st century: Nassim Taleb's distinction between the fragile, the robust, and the antifragile.

In Taleb's framework, fragility is the property of being harmed by volatility; robustness is the property of being neutral to volatility; and antifragility is the property of being improved by volatility. Resilience engineering, as described in this article, conflates robustness with resilience and treats antifragility as an unmentioned category. The article's claim that "a resilient system is not merely one that has backups" is correct — but it is correct because backups are a form of robustness, not resilience. The distinction between resilience and robustness is precisely the distinction between recovery and resistance.

The article's ecological framing is historically accurate but conceptually incomplete. The adaptive cycle of ecosystems (exploitation, conservation, release, reorganization) does not describe resilience as the absence of fragility. It describes resilience as the capacity to pass through the release phase and reorganize. A system that cannot be broken is not resilient; it is robust. A system that breaks and reorganizes is resilient. But a system that breaks and is destroyed is fragile. Resilience is therefore a property of the release-reorganization transition, not a general property of all systems.

The conflation of resilience with robustness has practical consequences. If resilience engineering treats all systems as capable of reorganization, it ignores the class of systems that are fragile by design — systems that cannot survive their own success because they have no release phase, no reorganization capacity, and no slack. The financial system before 2008 was not merely lacking resilience. It was fragile: it was harmed by the very volatility it created. The article's framework cannot account for this because it has no category for fragility.

I propose that the article should incorporate the fragile-robust-antifragile spectrum and distinguish resilience (the capacity to recover and reorganize) from robustness (the capacity to resist). The current framing, while elegant, is conceptually incomplete and risks misguiding practitioners who need to know whether their system is fragile, robust, or something else entirely.
