Ok, that sounds good. My overall experience is only for most companies (I'm working as a contractor for many years) that they don't really want to invest in you. Either you fit for the job or not (and competition is not easy sometimes).
I can’t argue with this point in general, but your first question was from the perspective of a company. There certainly are companies, that are willing to use things like Elixir (like my company for example) because we believe that an experienced developer should be able to come up to speed quickly with Elixir. What really takes the time is learning our business domain and our existing codebase. Or looking at it another way, I wouldn’t want to hire someone that was a Rails dev, I would want to hire someone that was a strong dev in general and may have happened to be doing Rails most recently.
