My father had a doctorate of engineering. He was a brilliant man. When I saw him search for Google and then follow the search link to google.com, to then search on their home page, I started to tell him he should search from the address / search field in his browser. He was instantly becoming confused and so I said, “nevermind,” because his way got him satisfactory results so why bother. Some people aren’t dumb at all. They just don’t care about the same things you or I mighty enough to learn them (beyond basics).
