Surely the point is that this developmental ability to persist is wasted on FPS?

Who is to say? FPS games can teach you about your physical ability, practice and teamwork as much as playing football or playing in a band. The physical skills are different, sure, but the planning, teamwork and execution are all very similar (and similar to developing an app with a team). Any of these things could also, well, not teach you much of anything. But is that a function of the game or the player?

The article suggests maybe it's a function of genuinely liking what you're doing vs simply wanting to do it (maybe because of an addiction).

I.e. the real problem is the opportunity cost

The problem with viewing through the lens of the opportunity cost is that it requires some hindsight to be completely evaluated. I played competitive football for 8 years. I wanted to, but I never went pro. You can work hard, put in the effort and still have nothing good to show for it. Today, I feel like I could have better spent that time, because it ate up a lot of it.
