I did the exact opposite: I have ~8years of professional ruby/rails experience and I was building a little SaaS. At some point, after 100 hours, I got bored/stuck with only 20% of the planned features to reach a MVP. I decided to switch to elixir/phoenix, where I had few confidence and there was apparently a growing ecosystem not always ready or complete. After 100 hours I completed the MVP and launched it. Using elixir was refreshing and right now I'm using it for almost all my side projects/prototypes.
