The topics covered in a CS degree don't really change much over the years, the point is not to teach someone how to write in a particular language, rather teach a deep understanding of structures, algorithms and math behind computers and programming.
For the most part unless you happen to luck out and work on something interesting there will be a cap on your career and areas you won't be able to work in. In some jobs a BSc isn't even considered enough and MSc is required.
