The main upshot seems to be a fine argument for Scala, really. They manage to somewhat indirectly argue that, if you want to be doing parallelism seriously, you should be using a functional language, but that people really want something object-oriented. So while they don't say so in as many words, they effectively argue that multi-paradigm languages like Scala and Oz are the way of the future.
And speaking of parallelism and Scala, the really hardcore may want to check out this presentation from ScalaDays (30 min video; here's the low-res version). It demonstrates a new open-source project out of LinkedIn, called Norbert, which provides a solid high-level API for creating and managing a distributed system of nodes for doing real work. Towards the end, he spends a while showing specifically why Scala worked so well for this -- not only the Actors architecture for parallelism, but also the rich trait system that lets them eliminate duplicate code.
