The Actor Model, Behind the Scenes
summary
Claims that actors are self-contained units with mailboxes that prevent race conditions and provide location transparency and fault tolerance. Code demos build a simple counter and a coffee-vending state machine wired to a live sequence diagram, using XState and the stately inspect visualizer; the coffee demo runs and shows state transitions. A multi-agent demo uses the Vercel AI SDK and Stately Agent beta to guess the word "coffee" and orchestrate client/server events, proving the actor-based orchestration actually works.
