Workflows as Actors: Is it really possible?

This post details how Temporal Workflows can be used to implement the Actor Model. It explains the core tenets of the Actor Model (message passing, creating other actors, maintaining state) and maps them to Temporal's features: Signals and Updates for message passing, Child Workflows for creating other actors, and the inherent statefulness of Workflows for maintaining state. It also discusses the use of Queries for retrieving state and the implications of long-running Workflows.
