Similarly I started programming very young. You do need to pursue other interests to be well rounded, though. But hey, not everyone is well rounded. However, I will say I think there is a difference if you are doing it because it is fun or you are feeding a thirst for knowledge vs you are trying to become the next Zuckerberg. There's a place for that, sure, but 13? I'm not saying this person is doing this, just remarking generally.
