I think this is a weak argument that ignores some of what the OP wrote.

A CS degree alone will not keep him relevant 5/10/20 years from now. The industry is, for the most part, a meritocracy, and he will need to keep his skill set up-to-date with industry trends forever.

In my experience, good CS students tend to learn more outside of class. Based on the OP's post, I would bet that he is sufficiently capable of self-educating.
