As a heavy Scala user I'm excited by this. But really I don't think it will improve Scala adoption because the blockers there are all around developer experience (tooling is terrible - sbt, and feedback cycles are very slow).
Personally, for a lot of my current use cases (APIs) I'm veering towards Go more and more as I find it a lot more productive.
At the Scala Center we’re working on addressing these problems. We now have working groups devoted to ease coding in Scala and make it easier for any dev to use any build tool.
