I made my first simple game app at 10 years old and I remember feeling that the concepts were fairly easy to grasp. Admittedly I was doing much simpler 80's BASIC programming, but I also didn't have the internet at my finger tips like your son has. I don't remember feeling too challenged when I learned algebra. It wasn't until I got to trig and calculus that I really started having to stop and think hard. As for my career, I've turned out to be an above average programmer but not superstar level. And I haven't lucked into any big dot-com jackpots, though I've tried. So in my opinion, your son is probably smart and could do well, especially if he learns how to stay focused. But I don't think his programming at 11 is necessarily proof that he is a genius or anything like that.
