The fact that many students learn Haskell in University and then don't use it in production isn't as much of a problem as the presentation seems to suggest. Programming in a pure functional language is a school of thought, a way to solve problems that's markedly different from OOP or imperative styles. In my education as a programmer Haskell has a special place and the way I use filter, map and reduce in production JS code is a small reflection of that. Ideas of Haskell have cross fertilized into many other languages, e.g. you can clearly see it in Rust.
