100% agree that shared mutable state should be minimized regardless of the paradigm used and further agree that it's generally not possible to totally eliminate it. I believe programming in a functional style helps on to adopt a mindset towards minimizing shared mutable state. Also believe functional programming gets one to think in terms of function composition. Even in an OOP-heavy language like Java, one can find themselves developing complex operations as a composition of simpler, reusable operations. While Java may not have proper 1st class function nor solid syntax for working with functional interface, one can still think in terms of composable operations.
