    From what I've heard all programming languages are object-oriented and that's a good thing. Well, for one thing, it makes thought organization easier. Plus once you mastered the idea of object-oriented programming, then all the different languages are a snap to learn. I've not heard object-oriented programming is a failure, or that programming languages are running away from it.

    Not all languages follow the paradigm of OOP. Many languages follow different paradigms. For an example, Visual Basic is an event driven language, and Haskell is a purely functional programming language. Furthermore, some languages, such as C++ allow you to mix and match paradigms in your code.

    OOP is an immense success. It is a major part of most successful real-world programming languages.

    Object-Oriented religion, on the other hand, is an incredible failure that cost, and still costs, billions in failed projects and unreadable code.

    The difference is subtle: OOP, when used correctly, is only one tool among others: functional programming, imperative programming, etc. Multi-paradigm languages such as Python, C++ or Go are good examples of this.

    Object-oriented religion, on the other hand, is a kind of cargo-cult programming: I've heard that objects are great, let's make everything an object! Let's force people to make everything a class, even when it doesn't match! We all know the result: the infamous AbstractSingletonGenericFactoryAdaptorFramework.
