The problem is that people take for granted that [insert code organization method here] is good and lack of it in another language is bad. This is a rehash of the conversation between Java and C++ proponents about the correct way to do multiple inheritance.

In practice, none of this really matters. For example, generics are just one way to do code organization, you can write codebases that are clear, maintainable, and reliable, without ever touching generics once.
