The one-dimensional pipe between two high-dimensional minds

A hand-drawn diagram titled “Asymmetry of dimensions” (次元の非対称) in Japanese. The upper half shows a timeline from 2022 to 2026. On the left (2022), a small human figure and an AI figure exchange one-dimensional text labeled “ABC…” back and forth. Moving rightward, the AI begins outputting images, then multiple modalities (image, video, graph, sound). On the far right (2026), the human still sends mostly text (“abc…”) while the AI returns rich multimodal content. The lower half shows two diagr

On AI, prompts, and the strange new asymmetry between two high-dimensional minds

Yesterday I read a piece by Joshua Leigh, “The Prompt is Not an Interface,” and it stopped me in my tracks. Leigh argues that decades of interaction design were spent moving away from typed…
