I think it’s subjective. I learned Haskell early on in university and I’ve learned Lisps and it still feels like extra work to reason about programs or model domains in functional languages.

I believe functional programming advocates when you guys say it works better. But I only believe it works better for you. In my experience there’s a minority of people who find functional programming to be a powerful paradigm shift but for most developers functional programming either doesn’t resonate or resonates at the level of an academic exercise that helps you think better about writing code but best remains an academic exercise.
