The post argues for replacing this pattern with an explicit FSM using the Elixir Finitomata library, which compiles a plain-text state diagram into a GenServer-backed machine. Benefits include compile-time validation of transitions, structural prevention of illegal states, built-in concurrency serialization via the actor model, first-class failure and timeout handling, automatic history tracking, and a dedicated testing API. Objections like 'over-engineering' or 'academic' are addressed directly. ## Full article daily.dev links to this article rather than hosting it.
