We are not booking flights or taking driving lessons. We are (hopefully) engineers and scientists. I find it perfectly acceptable that you chose to accept the abstraction of the machine. You may benefit from knowing electrical engineering, but I believe the benefit is slight. Knowing the history of the field is non negotiable however. You don't need to know how to heel-toe to drive to the market, but pretending that it's not a useful skill to master driving is ridiculous. Are you driving to the market, or are you a serious professional?
