while there is certainly merit to choosing a language with a large talant pool. It drives me nuts how so many employers optimize for hiring juniors. Hiring a Junior is like getting a puppy and now you're picking a language that minimizes the scale of their messes.

I'd rather hire someone that knows what they are doing and give them tools to maximize the scale of their strengths.

2 good devs working in elixir, rails or clojure will accomplish far more than 10 juniors working in javascript or go.
