> If you're trying to build disruptive technology, it seems obvious that you'll be better off using tools that are themselves disruptive. OTOH, tools themselves don't how disruptive your product is. The iPhone and Android are disruptive, even though Java and Objective-C are as boring as tools get (although the Dalvik VM is quite wicked). Find the best developers you've worked with and let them choose whichever tools they like. That being said, some of today's best Java developers will likely end up choosing Scala for a project they're building from scratch.
