You can see this as an implementation detail or also as a conceptual detail.

  I don't think it's conceptual. It's a technical detail. If they had been implemented differently, this would have made little difference to the programmer using Scala. Again, Objects aren't Java interfaces, so I guess the whole discussion is moot :)

    Yes, this is conceptual as you can conceptually regard functions as objects and it may have great benefits as a tool to communicate the idea to the other people. There are of course other abstractions with their own benefits.

      I disagree. Regardless, Objects aren't Java interfaces, so what are we even discussing? Uncle Bob wasn't arguing against the general concept of an interface, but about its specific meaning in Java.
