I regret using it. Recruiting risk. Smaller ecosystem. I should have gone for Python.
Hired a python dev at an elixir gig because I was forced to by the CTO. Picked by the CTO "because we need someone that can do python". Dev was absolute trash. Never hired a shit elixir dev. Python is a huge recruiting risk.
Don’t get me wrong. Phoenix is wonderful, Elixir kicks serious ass as a language. Jose valim is one of the kindest and most prolific guys I met on the net. I’d use elixir for a solo project any time.
