I've seen plenty of junior engineers who read a FP blog post, and start arguing about 'purity' and the need to refactor lots of code – without having any clue that pure functions are useful regardless of other coding paradigms / architectural decisions.

I'm very much in OOP-land when it comes to architecture at large, but a good portion of my code these days could be summarised as: using a 'classic' OO language to namespace pure functions.
