Resiliency means the ability to take a blow and not be bowled over by it; it means designing ones and structures that can bend but not break; it means blackouts that bounce back into brightness rather than cascade across the continent; it means backup systems so seamlessly integrated into primary systems that one doesn’t even notice the switch between them. Resiliency means accepting that sometimes things do break and then imagining and engineering ways not so much to make them unbreakable, as to consider how they might be less thoroughly broken in the first place and thus also easier to fix.
