I really wonder about the usefulness of implementing a language feature to reduce the need to copy paste in an editor.

  Generics are a language feature to reduce the need to copy and paste in an editor. For that matter, functions are a language feature to reduce the need to copy and paste in an editor.

  Really? You don't see the problem with trying to maintain code that's been copy-pasted everywhere with slight differences? Doesn't it seem easier to maintain one implementation of something than N implementations?

  Isn't that basically all language features? I could also write print("Hello") print("Hello2") print("Hello3") print("Hello4") print("Hello5") (which I partially copy-pasted above) but I use a for-loop instead.

  As a library maintainer, you can't copy-paste a line for a type that isn't written yet. As a library user, you can't copy-paste a line for a type you just created in a library you don't maintain. Being able to do what you describe lets a maintainer create an interface for all the future types that satisfy given requirements.
