I discovered Haskell in a comparative programming languages course I took at university last semester, and it completely changed how I think about programming. I can't speak for an industrial use case, but for a hobbyist writing open source software and personal projects, programming in Haskell has been an absolute joy and has reinvigorated my love for programming.

Tools like IHP (https://ihp.digitallyinduced.com/) are a great example of not only the beauty of the language, but when combined with Nix and the IHP IDE, a better development experience than I ever had with Rails or any other language.

If you are pragmatically minded, you can get stuff done in Haskell. In my experience there's a lack of online resources for this kind of work in Haskell, but that's what I and others especially in the IHP world are working on. If you just want to experiment, Haskell is great for that too.
