That is exactly what I think. If you got decent and educated developers, they should be up to speed fairly quickly. But management layers often have no trust at all, even if it would take maybe merely 2 weeks to be able to do basic implementations in a new language and ecosystem. Basically it means, that we cannot possibly spend 2 weeks becoming better engineers, but we can spend infinite time on wrangling with lesser tools.

I would love the chance to learn more Erlang (looked at the beginning of "Learn you some Erlang for great Good") or Elixir (used in last year's AoC) on a job and get to use OTP, watch it run my function calls on multiple machines and all that. I know a lot about functional programming, as I do it in my free time (big Scheme fan).

As it is currently, I cannot apply my skills at the job. For example when I think that some code should not mutate some state, but rather use pure functions and the tests should be simply function calls and checking the output, then I don't get the time to do that, nor the time to show how this would look like and how it would make things simpler. No one aside me on the job seems to be interested in purely functional data structures/persistent data structures either, which sooner or later are necessary, if one wants to make things purely functional. So basically I am the only person with that knowledge and cannot apply it. It is so dull.
