Roasting the Duck - A talk about Ruby and types
summary
Argues that adding types to Ruby via RBS + Steep gives real, concrete wins: improved autocomplete, navigation, refactoring and scalable refactoring across hundreds of lines, not just theoretical bug catching. Contrasts that with dynamic typing's practical advantage for the internet: tolerant, heterogeneous services follow Postel's law so runtime checking and flexible borders avoid brittle contracts. Recommends learning both styles or a gradual language that supports static tooling and runtime flexibility for libraries and large codebases.
