fast

An essay arguing that "fast" is a profoundly under-asked-for property in software but the one that quietly changes behavior most — fast deploys ship more code, fast tools (Raycast, Superhuman's sub-100ms rule, Mercury's instant settle, Instagram's optimistic photo uploads) feel like extensions of the mind, and fast signals discipline because latency exposes everything you couldn't strip away. Jue extends the argument to AI: today's LLM-augmented workflows are already 10,000x faster than what they replaced, but the developer experience around them is still clunky; the next wave of value will come when AI tools enter their optimization phase.
