The human species hasn't changed, the stuff they're familiar with has changed. And I think you underestimate the younger generations, I'm under 35 and could trivially identify a carb or fuse. Furthermore, I would be unsurprised if my 5 year old could also identify those inscrutable things, he 'helped' me get the snowblower ready for the season and winterize the power washer a month ago, and watched/helped while asking endless questions as I replaced the water heater last weekend. It sits adjacent to the furnace, which has a discrete Edison fuse; I don't recall if that was part of the litany but it probably was.
