Was referencing the run-time's viability on devices as small as a Beagle Bone micro controller, a mobile app, up to a backend service, etc.
There's an attractive opportunity for code reuse.
Have a preference for process pools over thread pools so don't mind the execution model. Would not be surprised that some applications are better served by other backends like akka etc. Elixir is on my list to learn.
That does of course play into the position that a great "full stack" framework is a thing of the past.
