If we forced everyone to switch to Haskell, do you think this would really be any different? People would still do the bare minimum to implement the latest user stories, because that is literally what the boss is paying for.
We force everyone to switch to Haskell. OK. Even the fair-to-mediocre programmers? Yes. Who tend to program by copypasta and change stuff until it gets the right answer? Yes.
Run away. Run far, far away. You don't want to see what "design patterns" and urban legends these people layer on top of Haskell to make it intellectually manageable.
I remember being a sophmore in college and I understood the basics of haskell (not really monads yet) and we worked in groups. My partner was very intelligent, but didn't have a grasp on the language at all.
For the final project, we had a problem that I didn't understand well, but he couldn't use the language effectively. We ended up having him work out the problem incorrectly in a shared notepad and I would refactor his broken code into something that worked. It was a mess. I'm pretty sure I've seen worst things you can possibly build in haskell -- and they are bad.
I think the point is to not force any single paradigm. OOP is what is being forced today, but it would also be bad if the industry forced functional programming. Large programs typically call for multiple styles of programming. One piece may suit an imperative style, another functional, another logic/relational, another object-oriented, etc. In general, I think OOP is nearly always the wrong tool, though.
I'm in university right now and there is an object-oriented programming course (which is required by most other advanced courses), but no functional programming course. That shows how skewed the industry is. It's a pretty forward-thinking university as well.
OOP is sometimes the right tool, but most times it definitely is not. It's important to be able to know your tools and choose the right one. The current situation is disappointing though.
In Haskell? I'm afraid the bare minimum is the most abstract possible engine with business rules added on as data or high level function application.
But I'm not really disagreeing. It's just that those people will spend months and months on some stupid repetitive concrete code, while the smart way would take a week, and the OOP way would take 3 weeks in Java.
