> "classes do not “model the real world”"

Classes are supposed to model sets (of objects), that is, instances represent real objects and classes represent real sets of objects. So the question is whether sets are as real as the members they consist of. For example, if a set of chairs is a reality that we can comprehend and want to represent in the system.

Yet, I think the problem is that we are probably not happy how classes model sets in OOP. They actually do not - and it is a major problem. (Classes in OOP are mostly templates for instantiating objects.) Also, we are not happy with how inheritance works and it also limits possible benefits of classes. But it is not a reason to say that classes per se are harmful. I would say that they are not as good as they could be :(
