>My last example was when I needed to batch sql inserts in an events database. In a normal language I would have needed a queue, the libraries for it, workers, new deployments and infrastructure to monitor, monitoring, supervision, etc... In Elixir, in 20 lines of code, it's done.

Can you provide more details on this? AMQP is pretty recent and people have been batching SQL inserts for much longer than it has been around. An external queue is not a requirement of non-Erlang languages, but I'm curious about specifically about how the implementation in Erlang would substantially differ/allow new approaches from that in other languages.
