Competent people, not "talent". Talented people are very rare, and the
chances are, you haven't ever seen one in reality.
And there are several things to note about hiring programmers for writing in
less popular languages: (1) it's much more difficult to hire an incompetent
idiot that knows Elm than similar idiot who knows C#, Java, or Python --
signal to noise ratio is much better; (2) there is such thing as Haskell tax,
which pretty much means that writing in Elm can be treated as a job perk; and
(3) you don't need people who know Elm, you only need people who can learn
it in reasonable time.
Especially (3) is important, because learning yet another language of the
same paradigm is not that difficult for a competent programmer.
