>Let alone that the entrenched, canonical, idiomatic coding styles of most modern oop languages encourage state, mutability, nulls, exceptions and god knows how many trivially preventable entire classes of errors. Granted, most have now started to come around and are adopting more fp features and ideas every year, but still.

State isn't a feature solely of OOP. It's very easy to see the FP craze as a similarly dogmatic insistence on pure everything as removing useful features instead of preventing errors.

If FP truly was the indisputable way of the future, Scala would be the CRUDspeak of choice by now.
