How much do you know about metallurgy, plastics, concrete engineering, hydrocarbon refining, etc etc etc all the thousands of extremely specific domains of expertise that modern society is built upon? The fact that you can possibly get more out of some tech by knowing how it works is because most of it is very new, which is basically just an anomaly that is fading. Eventually how computers work will be like those other things: expert domains that we rely on but users don't need to understand. It's already largely like that and that is good. I get that everyone here is a nerd and grew up tinkering with their computers and this makes them sad.
