There's some interesting parallels here. If you go deep enough into electronics, you'll run into physics again. The engineers working at the chip fabs (and chip design) work very hard to shield us mortals from the messy details - the idealized transistors and gates we work with in the digital world are a useful abstraction. (I hope never to need to learn about quantum tunneling!) In the same way, if you go deep enough into software design (whether "user-facing" or for other developers, you'll run into the messy vagaries of humans and our wetbrains. Whether you're dealing with the subcultural expectations of your audience for a drop-down vs radio-button, or writing a tutorial on how to use your library, or thinking about what features your fancy new programming language needs, we rely on the abstractions and rules-of-thumb that we've learned. But those rules come from deep places, using results from neurology, sociology, psychology, etc! Everything is deep, in every direction and all the way down. :)
