On the other hand I am impressed at how open industry has been to new languages since 2010. At the risk of dating myself slightly in the 2000 - 2006 era proposing a completely new language to solve a business problem was a much more radical idea. This was the era where you could get a lot of street cred and tech envy from hackers by just picking a non mainstream language (Examples - Viaweb using scheme, Naughty dog using lisp, Jane Street using Ocaml, ITA software using lisp). On an optimistic note I think there has never been a better time to ship new tech stacks, users are open to change and companies are fairly open to trying new ideas out.
