I think the way that we specialise from the start is unnecessary. From age 4, kids go to one place (or at least have set times) for maths, another for science, another for art, history, and everything else. Knowledge is so intertwined, it would be better if you could be learning all knowledge together, so they complemented each other. Then someone could notice what vision in machine learning, a certain painting from the seventeenth century, a reflexive verb in French and fluid mechanics have in common, and to write a paper under the title 'philosophy' about aesthetics. Or something. It'd just be nice to be able to use knowledge formally the you haven't had to spend twenty years studying.
