Ask HN: Am I too old to become a developer?

Hi HN, long time reader here. I am 29, and I've just been accepted into a Master's program in Computer Science. I am an engineer by eduction (not CS) and have been working in the financial industry (quite profitably) for the past five years. I have a good grasp of programming in several languages, but all for personal projects and fun, nothing professionally. Needless to say, it'll be a while before I'm a code-ninja; I haven't put in my 10 years. So my question is this: will I be considered too old to get into the industry 2 years from now? I want to do this more than anything else, and I personally feel that I'll be really good at it, but I would love to hear your views.
