Yeah. It's hard to express and understand nested structures in a natural language yet they are easy in high-level programming languages. E.g. "the dog of first

Yeah. It's hard to express and understand nested structures in a natural language yet they are easy in high-level programming languages. E.g. "the dog of first son of my neighbour" vs "me.neighbour.sons[0].dog", "sunny and hot, or rainy but not cold" vs "(sunny && hot) || (rainy && !cold)". In the past maths were expressed using natural language, the math language exists because natural language isn't clear enough.
