Elixir and Phoenix are living proof that functional programming can be easy - most of the time you just play with struct and functions, that's basically it. No need to pay attention to monads and type classes. On the other hand, it also reflects functional programming is also more straightforward than Object-oriented programming because it's more objective to just model the data, than modeling the data and procedures at the same time. If you have two people writing the same thing, there's a much larger chance they'll yield similar or identical results.
