It's not useful, interesting, or accurate to stratify people this way. You have no idea what someone's intelligence level or background is based on their usage of JS or C.

I loathe JS, but one of the best devs I know likes it. People's mileage varies.

For me personally, there's much more money in easy React products than making games. I'm not a great dev, but I'd be doing this same work even if I were.
