You want to know what's really amazing tech and underappreciated?

Scala.js- full power of both JavaScript and java/scala libs in a strongly typed well designed language.

You can't use all libs in it. Also you just ring-fenced a job a competent JS developer could do to now require someone that knows Scala and JS, which is a lot more cost per head and far harder to recruit.
