Jonathan Blow's "Preventing the collapse of civilization" [1] makes a similar point. It is easy to assume that, if we can build EUV machines and space telescopes, then processing stainless steel and manufacturing PCBs is baby stuff, and is just waiting for the proper incentives to spring up again. Unfortunately that is not the case -- reality has a surprising amount of detail [2] and even medium-level technology takes know-how and skilled workers to execute properly. Both can be recovered and scaled back up if the will is there. And time -- ten or twenty years of persistent and intelligent effort should be plenty to MAGA :)
