How long until you are competent?

I'm a high school senior who is very interested in programming as a backup option for if my acceptance to music school does not happen, or happens with too little scholarship money to afford it. I'm pretty big on math, and have done a bit of Learn Python The Hard Way. I guess my question is, with or without college, how long does it seem to take until most people are able to begin programming for money?

I know it's a lifelong-learning experience, but surely there has to be a point in which you can support yourself on your work.

You forgot Straustrup, but the real mastermind behind him was Alexander Stepanov, who did templates. And Grace Hopper here is just for feminist reason. Like there should be always a nigger in every Hollywood movie, so that nigger won't feel excluded.

Alonzo Church is just some minor mathematician. Haskell Curry and Moses Schönfinkel are much more famous.
