I've been a software developer for 20 years. i've been involved in language development and large data warehouse development. I've worked for start-ups that have gone public, and for government contractors, and I've written a published programming book.

My knowledge is either self-taught or on-the-job. I've worked with some of the best and brightest, and they taught me well. I'm back in school now, and am weighing my options, deciding between a Computer Science and a business degree.

My question is this. What do I gain, at this point in my career, by earning a Computer Science degree? I just don't know if a Computer Science degree, at this point, is a value-add on my resume.

Edit: I'm working on completing an undergraduate degree.
