Seems like you have bad experiences with functional programming, but it's a little strange to rat on the advocates that are trying to figure out how to take potentially useful functional programming concepts and make them mainstream and/or explore alternative ways to quickly build robust systems.

Good examples of this translating to huge gains for the overall community are React + Redux.

I'm quick to admit that functional language ecosystems are not as mature, which might lead to lesser organizational productivity but no need to rat on functional programming in general.

A lot of things seem to get lumped into “functional” programming. The lexicon changes so I may just be behind the times, but ensuring every condition of branch logic is covered is not an aspect of functional programming as I understand it. And I may be wrong.

Without getting into what is and isn’t functional programming, exhaustive pattern matching is a very useful feature present in some functional languages.
