Getting back to the original question...
Basically I don't even know if the guy is watching his airplane. I have never even considered telling somebody to find a different hobby, but this guy is my first candidate.
I saw a case like this at my field, with a very experienced instructor. I sometimes hang around the instructors to pick up tips (since I learned with a very inexperienced--actually no experience--instructor). What got my interest was the instructor was saying stuff like, "You have to look at the airplane to fly the airplane," and "Did you see what the airplane did?" I really don't know what the issue was. It was a teen, and it appeared his father wanted him to fly a lot more than he did. It wasn't like the kid had an attitude, more like he was really spacey. It was strange, almost like he didn't understand the connection between his fingers and what the airplane did.
