Sorry, I'm still not sure I understand. You're saying that computer science is one of the specific areas whose research focus does not and should not coincide with "real-world needs," in contrast to history, economics, biology, law, and music? Or am I misunderstanding you badly?
What other fields of study are like computer science in that they shouldn't be about real-world needs? For a given discipline, how do you tell which of the two categories it falls into?
