The post traces the evolution of asynchronous programming from simple sequential code to modern patterns such as callbacks, promises, and `await`, highlighting how each step added more abstraction to manage parallel flows. It then introduces the Actor modelâactors that receive messages, become functions via a âBECOMEâ method, and communicate through events like READY before being connectedâillustrating its use in visual programming where components must be fully initialized before wiring them together. Finally it expands on higherâlevel abstractions: supervisors that queue work for workers (each an actor turned function), enabling parallel execution across CPU cores, automatic retry and recovery when tasks fail, and even human interaction by waiting for user input before marking a job complete. The result is a selfâhealing, highly parallel system built from simple actors to sophisticated supervisor/worker pipelines.
