Well, they are listing what are obviously the most widely used languages in the industry - C, Java, C++, SQL, JavaScript, R, HTML&CSS, Python, C#, Go, Bash, Assembly; and a few of the better known but more niche languages - Ruby, Swift, Objective-C, F#, Erlang, Rust, Kotlin, TypeScript; and still a few others. Together, these cover cloud programming, web, embedded, desktop, mobile, OS, networking, games, machine learning, data science and probably quite a few other industries. The only languages I can think of that see quite a bit of use and that are missing are Lua and TCL; and some of the more obscure ones that would still have been interesting are Ada, some MLs, Haskell, and CommonLisp. Why do you believe that this list is biased towards web development? And, out of curiosity, what languages are you working with? By your mention of Emacs, I'm thinking maybe some kind of Lisps?
