Not getting a job is one risk. Loosing the interest in CS is another. I know a fellow who was very much "into computers," decided to become a programmer, signed up for the (offline) classes and then had massive troubles trying to understand how a do-while construct works. He was in mid-20s back when it happened, spoke 3 languages and had a day job as a nurse. He did finish the course, got his grades, but ultimatley lost all the interest and never got into IT.
