Programming languages vary across a spectrum of expressiveness. By expressiveness, I mean the ability and ease by which you can express something in a particular language. For example, programming languages having closures are widely considered to be more expressive, and hence more powerful, than languages that lack this feature. I wonder if natural (human) languages also vary in expressive power and if so how this affects your thinking and personality. If you grew up learning the most expressive natural language of all, would that make you smarter than those who didn’t?
