Our system is so interdependent that a electromagnetic pulse from the sun or nuclear weapon that knocks out the grid also knocks out transportation and the financial system. Oil decline will eventually lead to the end of transportation and fall of civilization as I explain in my book “When Trucks stop running: Energy and the Future of Transportation (Springer 2016). When you add in declining resources (especially phosphorous which is essential for agriculture), corrosion of infrastructure, climate change caused food reduction and rising oceans plus all the other factors in decline and collapse, it wouldn’t take much to turn a gradual into a fast collapse. My gut feeling is that there will be a fast crash that would take years at worst (EMP or nuclear war), and decade(s) at best. Certainly not centuries.
