I think this depends. People who need basic computer functions can get on very well with linux.
My classmate in highschool had ubuntu on his home pc as long as I remember, because someone preconfigured it for them and it was mainly a browser - schoolwork machine. He gamed on XBox. There was no hassle, it was fine.
My mom on her run down laptop has mint now, because I configured it for her. I haven’t heard any complaints.
E: Also many hospital here run Linux and it is just fine, and trust me, many of the medical staff are barely tech literate enough to register for email themselves.
Linux is a problem for people who come from windows and need more than basics but are not tech savvy enough to get their hands dirty. Then once your comfort level with tinkering goes up again, Linux is once again not a bad recommendation. It really kind of is the bell curve meme.
