Even large companies are still grasping at straws when it comes to good code. Meanwhile there are articles I wrote years ago which explain clearly from first principles why the correct philosophy is "Generic core, specific shell."
I actually remember early in my career working for a small engineering/manufacturing prototyping firm which did its own software, there was a senior developer there who didn't speak very good English but he kept insisting that the "Business layer" should be on top. How right he was. I couldn't imagine how much wisdom and experience was packed in such simple, malformed sentences. Nothing else matters really. Functional vs imperative is a very minor point IMO, mostly a distraction.
