> There’s growing skepticism toward OOP, and that’s reflected in the popularity of languages like Rust and Zig, which are explicitly designed to push against traditional object-oriented patterns.

I don't know about Zig, but my experience with Rust's trait system is that it isn't explicitly against OOP. Traits and generics feel like an extension and generalization of the OOP principles. With OOP, you have classes (types) and/or objects (instances) and bunch of methods specific to the class/object. In Rust, you extend that concept to almost all types including structs and enums.

> OOP, by contrast, offers a new conceptual lens: objects, inheritance, polymorphism, and eventually design patterns.

Rust doesn't have inheritance in the traditional sense, but most OOP languages prefer composition to data inheritance. Meanwhile, polymorphism, dynamic dispatch and design patterns all exist in Rust.

That’s not oop. Traits and generics are orthogonal to oop. It’s because oop is likely where you learned these concepts so you think the inception of these things is derived from oop.

What’s unique to oop is inheritance and encapsulation.

Design patterns isn’t unique to OOP either but there’s a strong cultural association with it. The term often involves strictly using encapsulated objects as the fundamental building block for each “pattern”.

The origin of the term “design patterns” was in fact established in context of OOP through the famous book and is often used exclusively to refer to OOP but the definition of the term itself is more broad.
