In my experience, setting up gRPC often involves a lot of boilerplate, particularly with code generation when using libraries like Tonic. While gRPC is great for well-defined, schema-driven communication, one of the big advantages of distributed actors in Kameo is that you can communicate with any actor on any node without the need to define a schema upfront.

With Kameo, an actor running on another node is simply accessed through a RemoteActorRef, and you can message it the same way you would interact with a local actor. This flexibility allows you to avoid the overhead of schema management while still achieving seamless communication across nodes, making the system more dynamic and less rigid compared to gRPC.
