In engineering, it’s called a cascading failure. Event one, oil running out, causes event 2, blown bearings, causes event 3, locked wheels, causes event 4, multi-car pile-up, causes event 5, massive shooting incident as protection teams assume it’s a trick, causes event 5...ending with the fall of banks, nations, the European economy, the Fed steps in with a massive cash infusion, Unicorns appear. Cue dramatic music…The oceans begin to recede, Earth begins to cool, we have a dialog on race, everybody kills everybody else, ‘cause these things to not work out.
” For want of a nail....”
Bump the engineering thing, but that is physics and logic. check the tagline.
