I code in a few languages and I’ve always wanted to know more than one “human” language but efforts in that area have more or less consistently failed (exception being Esperanto because that’s easy, but since hardly anyone speaks it it’s not exactly useful).

Despite my interest in both I doubt there’s much of a correlation when you look at programmers (or polyglots) as a group, though. For all we call all of these things “languages” there’s a pretty big distinction and difference in complexity and approach between the computer and human ones, it’s a whole different hobby.

I’d compare coding more to other hobbies that involve making things. I knit a jumper, I develop a video game…scratches same itch.

Or possibly problem-solving hobbies. I work out how to adjust a sewing pattern to fit, I solve a tricksy sudoku…again same itch.
