On “How comes OOP overemphasises nouns, as opposed to FP?”

[video I can't blame you for doing so because the majority of (popular) OO languages (and consequently their libraries) assume mutability, but it's perfectly possible to have purely-functional, immutable-by-default, OO languages. Though this may not be reflected by the popular languages of today, OO does not imply mutable state or in-place modification. As I said, it's perfectly understandable, but nonetheless you're conflating two very different things.
