We’ve skipped so many additional things like Redis, Memcached, Sidekiq and tons of libraries because it’s so easy to write a module to replace stuff.

Switched from ruby to elixir 4 years ago and the only time we touch ruby is to maintain some old system.

It’s so darned easy to add functionality to an exiting app that you have to be careful of bloat.

And the functional paradigm is like second nature now. It’s hard to go back to a non functional language.
