The brain of a baby is a tabula race, at the moment of birth all children have approximately equal prospects, with rare exceptions. But about development ... this is where difficulties begin. All sorts of motivations, stimuli, psychological blocks and much more. As a result, some children develop better, others - worse. Someone grows up to matan, someone stops at simpler ideas (like me), well and someone even hardly masters the work of a loader. But since some humanitarians are a little complex, then here you and "all have different interests", and "it's all far-fetched." Because in the end there is a difference, and quite noticeable. And if a conditionally average physicist masters philosophy ... well, maybe for a couple of hours, of course, but without in fact on rsslabone, then the conditionally average philosopher he will never master any thread of quantum theory.
For myself, I can say that it is far-fetched. I see no barriers to solving technical problems and just as freely I can talk about a person and the culture he produces. Therefore, I absolutely cannot apply to myself either the category of "techie" or the category of "humanities" - I just take and solve the tasks set for myself, no matter what bias they may be.
All this is far-fetched. People are not divided into humanities, technicians, or natural scientists. But each person has a certain way of thinking. And everyone has their own interests. Therefore, already in the process of development and learning, a person chooses the direction of interest to him.
