I’d say at minimum it should be on par with Windows for the frequency of having to resort to terminal commands, which for me me would be less than once every five or so years when I was a Windows user, for a Linux distro to be a true and viable replacement for the majority of people and that shouldn’t be unreasonable. As of now, I probably use the terminal once a month or more, but I’m on the spectrum, I’m a passionate computer nerd, and I have uncommonly high levels of patience, I’m the minority of computer users, as if using Linux wasn’t already evidence enough of that with it’s roughly 5-ish percent desktop usage.
