Computers are magic to the majority. I bring up in a previous reply that mirrors, and now lights, pedals, and other controls, that these are directly user-facing and must be interacted with in order to get anything done. Even knowing there is an engine that might need engine-y things like water and oil. But where is the requirement a user knows about URLS in order to use the web? Way back when we had AOL keywords.

But why is it that computers are that magical? Computers have been now around for nearly 70 years. It's a technology as new as airplanes were in 1980. (If we include digital accounting machines with storage, they have been around even before the first flight of the Wright brothers, they are even older than any living person.) Computers are also the means by which many, if not most, are dealing with for a living on a…
So, it's entirely unfair to suppose that since people got used to having tap water and so we are surprised if a person can't operate a tap, therefore they should be used to the entire complexity of computation by now.
You definitely _should not_ count machines that aren't actually computers ("digital accounting machines with storage") since those aren't Church-Turing, they're just another trivial machine like a calculator. Instead, compare the other working example we have of full-blown Church-Turing: Humans. Why aren't people somehow used to everything about people yet? People have been around a long time too. Why isn't everyone prepared for every idiosyncratic or even nonsensical behaviour from other people, they've surely had long enough right?
