If you're truly committed to "the right tool for the job" be prepared to become a polyglot programmer. We use 5 (or 6, depending on how you count) different programming languages regularly at my startup and for strong business and technical reasons each of them is "the right tool for the job". We also have some other languages squirreled away in odd corners. In those cases, the languages tend to be "good enough" tools for their jobs (so there's no sensible reason to change something that is already working).
