Asynchronous hamburgers
summary
An animated cartoon builds a miniature responsive hamburger restaurant to show synchronous blocking, a parallel approach that calls customers back, and a pager-based promise that lights when a burger is ready; the story names an actual surprising latency — 500ms — and demonstrates the failure modes: stuck customers, a callback that hands out the wrong phone number and produces callback hell, and a pager solution that mainly removes waiting but exposes new coordination bugs.
