For the average person: light bulbs, air conditioners, refrigerators, microwaves, radios, etc., etc.

Perhaps but I think there’s a difference. I don’t know how refrigerators work, but I can guess and within a few guesses I’ll probably get close.

I don’t know if everyone can guess how comp tech works. I’ve heard comments about how hard it must be to code how software works. Or to understand that so much can happen behind the scenes

I think most people probably can't guess how a refrigerator works. Maybe if they remember high school physics, but I wouldn't put money on it.

Maybe I'm just pessimistic but I think you're overestimating the understanding of science the average person has.
