Who cares if it's electric or ICE, how combustion or regenerative breaking works, why you need to balance tires, how to change brake pads etc. I take it to the mechanic (IT Department) and they do magic, then give it back to me.
Same for computers. Why does the user need to know about USB 2 vs 3, memory, disk space, multi-threading, ad blockers, etc. Turn it on, use it, and send it out to be fixed when it doesn't work.
