There is a benefit of being a life-long learner, and with all of the free courses out there, it is a great time to learn.
As I've mentioned before, there are a lot of resources available to obtain alternative credentials. Although you may not get an official degree from taking these courses, you will still learn the material and be able to apply it.
aGupieWare has recently put together a free bachelor's level computer science curriculum based on free available courses.
The curriculum offers introductory courses, core courses, and electives with links to the respective free courses from MIT, Harvard, and Berkeley to name a few.
If you have the dedication and discipline to follow the curriculum, many of the commenters believe that it accurately reflects the knowledge you would obtain in a "real" computer science program.
