You mention physical electronics. After the raspberry pi wave I dabbled into electronics, thinking I would have an easy time, boy was I wrong :) There are so many things even for the tiniest circuit. And yeah even soldering is a sophisticated piece of knowledge with moving parts everywhere (alloy, flux, iron, board geometry and layers, ground planes) and you quickly get a sense of: I need to KNOW how to solve this good and fast. Not just "just use that tool and maybe it will work". It went to the point of rewiring how I approach software.
