If Java is a tool that provides the functionality needed for a particular developer, why investigate a new language? Seriously? It isn't just a case of the developer and the language features that matter to a commercial business, there are the IT folks running the thing, their familiarity with the tools, the logging facilities, etc. Tools are great and learning new ones is a good thing. But articles like "X should look forward to/embrace Y" are short sighted unless they take into account the simple fact -- what is the end goal. If it is shipping product, the whole team needs to be on board from design, implementation, running, and maintenance.
