What I learned working with the Akka framework in Scala is that actors are a really nice concurrency primitive, but I don't generally want to be writing business logic on them directly. I don't know about Ruby, but with Akka, there are all of these higher level constructs, like Akka Streams, which make better building blocks for business logic. Another thing to note is that famous actor-based platforms, like Erlang's OTP and Scala & Java's Akka, offer a lot for building network distributed systems with features for dealing with faults. That's a big part of their appeal. Not sure whether Ractors offer that.
