Food for thought. Your comment shows a wide range of knowledge and covers things I haven't thought about. I was reading about the history of Simula and how the majority of OOP features originated there. It was built as a simulation language, hence the name. I took from that it was designed to simulate the real world - I guess based on the below that's akin to simulation of mental models. I did briefly think about the quantum mechanics rabbit hole. You make a good point. I'll think about this more. People can tell what a radio is because they have a general idea of what a radio does - has a speaker, volume, aerial. This is what led my thinking. I'll think more about this.
