Is it really so hard to take existing talent and train them to use other languages? Especially in cases where the existing library and tooling ecosystems exist (e.g. anything based on the JVM) the actual language probably won't be a show stopper for the level of talent you need. If a new language takes a couple weeks to get up to speed in, so what? The bigger problem, IMO, is the existence of libraries and basic development tools like build systems and dependency management. I'm fairly pleased with how many of the newer languages that build on the JVM allow easy interop so that you can use the existing ecosystem when it makes sense.
