THE INTERFACE IS NO LONGER THE PRODUCT

Summary from the TLDR Design newsletter

AI agents don't need traditional interfaces like menus and canvases — they require structured data they can directly read and modify. Current software categories like spreadsheets and slide decks are historical accidents based on human interface needs, not fundamental requirements. The future lies in apps built around structured representations that agents can inspect and validate directly, with traditional interfaces becoming mere output formats rather than the source of truth.
