As long a you don't intend to get work from it, there are tons of alternatives for learning the information that would be contained in the course.
Typically speaking, just doing the necessary coursework, as Scott Young did, isn't enough to make you employable, even if you do it in a context in which you end up with a degree. It's a good part of it, though, since it certifies that you would be able to use the same words to communicate about algorithms, etc., when talking to peers, which is something you probably wouldn't be able to do otherwise. A lot of the communications in any technical field takes place in a higher bandwidth shorthand, or jargon, which lets you communicate a lot of information in a short amount of time.
Consider, for example, if you don't speak portuguese, your teaching credential and experience, valid though it may be in an English speaking country, won't transfer over directly to being able to teach even your top subject to a non-English speaking class.
