Hasn’t it always been the case that the current generation skips learning about useless lower layers used by older generations? How could it be that the layers you grew up with and learned are the special ones which are still useful, when all the layers which came before, which people at the time thought essential, have turned out not to be so?

I.e. why is it that C and assembler is “fundamental”, but electronics is not?
