> They will have a tool that does everything and asks for nothing, and they will be as easy with it as you are with the light switch you never once thought about.

Oh come on! Of course I wondered how a light switch work, and I then learnt. I remember taking apart broken electronics as a kid, and that later morphed into also trying to repair things. Including the computer (both hardware and software wise). I remember ending up reinstalling the OS so many times as a kid on the computer I had access to when I broke it in various ways past what I was able to fix.

Sure, not everyone will have that drive to understand how the world around them works under the hood. But for engineers and scientists I would expect a far higher percentage to have that sort of personality.

It doesn't matter if it isn't "pushing back", just that I don't understand it is enough to catch my interest and a reason to go poking at the thing.
