It’s an operating system that demands more of you than does the commercial offerings from Microsoft and Apple.

It's different, but I imagine they're not fundamentally different if you exclude established knowledge/already being used to something.
Normal office use for non-techy people is launching apps, editing documents, and surfing the web. That doesn't work much differently, not fundamentally different, and not fundamentally more difficult.
Does it need more than the borrow checker if it's a game changer?
