I think, in my ignorance, that this is a deeply human desire to understand the world or at least parts of it. If there is a simpler, less complex concept you can grasp it's always something that appeals to some. And also there is a need for belonging and FOMO, so if you find a nice subculture that appeals to you and is graspable in it's complexity, it's way easier to stay informed and connected in that, than a more general topic. Specialisation is indeed is the only way to understand something to the state of the art for more than two centuries or so now, since it's humanly impossible to have a working understanding of the whole of human knowledge.
