"Whow as a physicist, former submariner, involved in advanced technology all of my life, Trump drove this nail in with one hammer blow. The behavior of complex systems is not predicated by an analysis of each step in a process because it is all too complex for such an analysis. I have seen project after project go disastersouly awry because of this. And of course we all see this in software that started as a simple workable program (now called an app) that is in an endless do-loop of patches and upgrades because some kid decided to add one more really awesome feature."
