I think a better comparison is a game like chess. Is chess useful outside of being a professional chess player/instructor? No. So being a chess Grandmaster is every bit as useless as being a spelling bee champion, apart from the prestige.

Frankly, that's probably more useful than learning how to throw horseshoes.
