No, it doesn't. Most people deviate from the norm on something. Age, gender, disabilities. So what?
As a teenage programmer, I can say that teenage programmers aren't that uncommon any more. It's not remarkable, age really doesn't matter. Anyone over the age of 10 can learn programming by taking programming courses from world-renown universities nowdays. I'm 16 and I've been programming for years. That's only because I had a chance to learn programming and I took it, not because I'm more intelligent than a someone who's 20 years older than me and only got a computer when he was 18. Other people at my age didn't have such chances, and I'm thankful.
