Yes, ok, he is 18, that's true, so my post is probably a bit harsh. But still, if he keeps that attitude he'll be 30 or 40 and use Django in a time where everyone has moved on to new stuff(tm).
I think he's the kind of young developer that when he moves on to university or the workplace he'll rapidly broaden his skills.
Telling me a developer is likely to get the same kind of experience working bit jobs as a contractor in high school as they are either doing the same while pursing a CS degree, or working in a development team is preposterous.
Edit: I just realised you're the OP. Add "gaining some maturity" to the things you'll get from the above.
