Object-oriented programming (OOP) is an ancient (25-year-old) technology, now being pushed as the answer to all the world's programming ills. While not denying that there are advantages to OOP, I argue that it is being oversold. In particular, OOP gives little support to GUI and network support, some of the biggest software problems we face today. It is difficult to constrain relationships between objects (something SmallTalk did better than C++). Fundamentally, object reuse has much more to do with the underlying models being supported than with the object-ness of the programming language. Object-oriented languages tend to burn CPU cycles, both at compile and execution time, out of proportion to the benefits they provide. In summary, the goods things about OOP are often the information hiding and consistent underlying models which derive from clean thoughts, not linguistic cliches.
