Only that nothing about this requires big expertise. If you are a user of computers, you should be able to navigate the basics. It's the same like driving a car, you must know the traffic rules and how to behave, but that doesn't mean you have to understand how your engine works in detail.

If you want to drive a car you go through driving school and have to pass the tests to get a drivers license. Theres no drivers license for the internet and not really any strict set of rules you have to follow in order to get online - most people pick up a sense for rules online by osmosis, usually about how to not get scammed or get malware - sometimes they have to learn by first hand experience. If we go by your comparison this would be like learning to drive by crashing a couple cars. I definitely believe anyone whos even a little tech savvy underestimates how complicated or confusing technology can be for the average person.
