The author animated two identical AI responses: same answer, same generation pace — the only difference is whether text appears as it's ready or after the whole thing completes. The empty screen makes the gap obvious, showing streaming means earlier reading, not faster computation.
An interactive explainer site (explain-lab) accompanies the demo, narrated by an AI clone of the author's voice — part 1/6 of the FastLab series.
