A 1983 Apple IIe puts a letter on screen about 30 milliseconds after you press the key. A modern web app, running on a processor a thousand times quicker, often takes five times longer. We spent forty years of Moore's Law and handed the budget to abstraction: layers of frameworks, compositors, network round-trips and animation, each adding a few milliseconds between your finger and your eye.
You feel it without naming it. The faint mush when you type into a chat box. The beat before a key registers. It is not your imagination, and it is not nostalgia. It was measured.

Nothing on this page was sent anywhere. The lag you felt was simulated locally,
from real measured numbers, just to make four decades tangible.
