Agreed. The BEAM run-time and the preemptive scheduler implementation is designed to never block and keep chugging a long; highly desirable for the Actor model. The trade-off is you're further from the metal and raw-compute isn't as powerful as a JVM language like Scala. That said an Actor model on the JVM (Akka) can't make the same run-time guarantees using a cooperative scheduler; instead you get all the enterprise libraries and developer hours to tap into. So the trade-off of more complexity in Scala/Akka is probably worth it for big enterprise who are probably already in bed with the JVM.

I think we'll see more Akka features built in Elixir through things like Genstage and Flow, but it's hard to argue with the mountain of exiting developer man-hours in the JVM.
