The thing about democracies is they are resilient but appear resilient. Autocracies are fragile but appear resilient. This is because democracies have open debate about policy, and criticism is an integral part of the system. This disagreement appears chaotic but actually helps the end product of things like legislation work better. Autocracies, on the other hand, discourage open discussion of policy, which creates a veneer of unity, but makes the end product worse.
