It’s a moot point, because the average user doesn’t install any OS on their system. They get people like us to install it for them.

They don’t generally solve their own Windows problems either. OEM is the real bulwark of of Windows dominance. Usability and familiarity is one aspect, but I’ve set a good few people up with Linux at this stage and very few of them know what a kernel is, or what Plasma/Gnome are, because they don’t need to (same way they didn’t know or care what NT was either).
