I expect my computer to work effortlessly like any other appliance
None of your appliances have the power and flexibility of a computer. At least mine don't. I don't recall my toaster being able to wash dishes, mix cake batter, keep foods cold or frozen, and wash my clothes. That's the sort of flexibility all personal computers have (at least in theory).
I don't want to take several college level courses just to use it. You don't have to be an automotive engineer to drive a car, why should a computer be any different?
You were born before computers were commonplace, unlike cars. You grew up watching people drive, watching them maintain their vehicles, etc. My kids will view computers just like a car or even a toaster.
BTW, if you had to lay hands on your car like you do with a computer, you'd need several college level courses to be successful (or at least a lot of hands on experience). People who have neither are just as stymied by their cars as they are by their computers. Afterall, what we're talking about here is repair and maintenance, not day to day operation.
FWIW, well maintained computers need little day to day maintenance, just like modern cars.
