To put it simply, the BEAM lets you swallow all of your dependent services into a consistent API, no matter network distance or machine dependability. In Python it feels like my main thread, DB, job queue, and OS are all speaking different languages. With Elixir I don't spend much time at all getting different services to work together, at least an order of magnitude less.

Elixir is not perfect, but for me working alone dependency hell was the bottleneck with Python. Now the bottleneck is adding features, which is right where it should be.
