It&#8217;s not just that highly interdependent networks, when run for efficiency rather than robustness, will be breakage-prone. I recall being very dissatisfied with the way Jacques Tainter in his book Collapse argued that societal decay resulted from the rising costs of complexity in energy terms. While that&#8217;s a persuasive argument, he dismissed all theorists who argued from cultural causes basically as Romantics who were decidedly lacking in rigor. The problem, however, is that Tainter &#8216;fessed up in an aside that the elites in some societies that started on a collapse trajectory were able to pull themselves out of the nosedive and others failed. Yet Tainter had no explanation as to why. If it wasn&#8217;t culture, what was it?
