Efficiency is the removal of redundancy. Redundancy is a necessary element of resilient systems. The unbounded search for efficiency has one result: brittleness.
@ekuber Yes this is true, but there's a new kind of efficiency hindering process that provides no resilience against crises. It's things like Billionaires who, increasingly, not only waste valuable resources directly, but also influence policy making into wasting even more resources. It's what got us into car-centric worlds, despite of cars being highly inefficient and fragile systems.
