Unfortunately, knowing all this won't help you get a job when the market demands an army of React devs and little else. Under our current system, knowledge that cannot be monetized is useless. Worse than useless, in fact, because time spent learning low-level concepts is time that could be spent learning marketable skills. The industry is effectively paying us all to forget. Sure, learning the USB stack and differential signaling is fun, but unless my job involves implementing custom USB devices from scratch then it's pointless trivia that won't pay the bills.
