A better analogy might be two different positions in basketball: shooting guard and center. To some degree, the two positions specialize: SG doesn't need to block shots (let's say), while the center does. However, everyone needs to dribble. A simple CS concept like recursion is analogous to dribbling. If you can't dribble, you're not playing basketball. If you don't know what recursion is, you're not a professional. Period.
