Removing inefficiencies when circumstances are as anticipated means that there isn’t much slack in the system to respond when the unanticipated happens. Optimization is intrinsically brittle , because it’s about closely matching the outpu

Resilience requires a kind of elasticity, an ability to stretch and reach but then to return, to spring back into a former shape—or perhaps to shapeshift into something new if the circumstances require it. Resilience is stretchy where optimization is brittle; resilience invites change where optimization demands continuity. But whether we’re talking
