The differences are very small, and I am not too surprised with the relative popularity of Matlab and R compared to say Haskell, since there are relatively more women majoring in engineering that computer science, as well as relatively high numbers doing quantitative work in the social sciences. I wonder why Rust, though, is such a huge outlier. Maybe it is just noisy because there are so few people asking about Rust at all on Stack Overflow.
