OOP is not about doing things harder, it‘s about doing them efficiently. The key elements of software engineering are abstraction and encapsulation: we, humans, cannot load the entire domain into our memory and reason about it at all levels of detail at once. We need to zoom in and zoom out, decompose problems into smaller pieces, then reassemble, treating those pieces at surface value. OOP isn‘t rocket science, it just adds one more piece — the hierarchy of concepts with inheritance and polymorphism. And it‘s just a technique: most programs are written in a mix of styles anyway. The foundational style is procedural, because that‘s how computers work. FP and OOP just build on top of it and translate to it.
