I think OP may be confused that a lot of CS shouldn't be programming language specific. I haven't touched a lot of the languages I learned in college, but knowing specific patterns, data structures, algorithms, control flow, etc and how they may be integrated into the language I am using, whether as a feature of the language or even part underlying VM helps immensely when making intelligent decisions structuring my program.
