That's not what I said. I said that no one would say that Scala can replace Java in all circumstances. Opinions vary greatly on what percentage the appropriate circumstances are (I think Scala is rarely a good replacement and never given the alternatives, while others, like you, say it's a good replacement in most circumstances - but not all).

In short, no one (who knows the software development landscape well, that is) can say Scala (or some other JVM languages) makes Java redundant.
