If you decide that a language you do not have experience with is the best language for the task, that will hopefully be just that. It's all in the constraints of the problem, what's important, time to delivery, total cost of ownership or whathaveyou? Intel and GloFo spend billions of dollars in developing new factories to produce smaller transistors. Then they spend less money to refine the process, then they build newer factories that can produce smaller transistors. Sometimes it's worth investing 4 months into tech (Scala) that will be more beneficient for you in the long run. I spent almost 10 years doing Java, and I refined my skills until I felt there wasn't anything more to refine, and to produce better software, I needed to invest time into a new technology (Scala). With that being said, I am a worse Scala programmer than a Java programmer, but I now produce more features, at higher velocity, with lower maintenance cost than I ever did with Java. There is no one-solution-fits-all, everyone has to decide for themselves what is most important to them, both in the short run and in the long run.
