As someone who is huge on Functional Programming, I'm not sure you're reaping the benefits you're talking about. Your dedication is impressive, but it's nowhere close to being required to build any kind of product. Sure, I agree that learning FP will make you a better development, but spending all these learning resources in order to build a product is not very convenient. I've been shipping code with mediocre languages all my life. Even now, I routinely pick node.js over Haskell or Rust just because the complexity of the solution I need to build is not high enough to justify writing amazing bug-free code. Sure, you may get more bugs and less help from the compiler, but there is more material online and I can easily find a cheap developer to throw at the project. I've been developing for 15 years. After 5 years of C++, PHP, JS, I decided to jump into Haskell for my side projects. I can't say the learning curve was as hard as you made it out to be: there are plenty of great resources for learning Haskell and you don't need to go through Elm or Purescript (which weren't even a thing when I learnt Haskell). Actually the differences between the languages may make things more confusing. In the last couple of years I stopped using Haskell completely, simply because Rust (a language designed to build things, unlike Haskell which is more of a language research project) is functional enough, pleasant enough to use and is developing a nice community. The most useful FP concepts trickled down in other languages. FP already won and nobody even noticed it.
