So long untyped actors, make way for Akka-Typed
summary
Akka Typed brings compile-time message protocol safety to Akka actors by replacing untyped Actor.receive with Behavior-based APIs that return the next state instead of mutating fields. The talk shows a Scala ticket-reservation actor implemented with tell/ask semantics, supervision strategies, and lifecycle handling (stop/cleanup), and highlights that sending the wrong message type fails to compile, preventing runtime misdeliveries and simplifying state reasoning.
