Convergence
Three operators (and Gartner forecasts) converge on a UX/product reframe: agents and machine-customers are now first-class users of B2B and B2C products. Design for reliable structured output and natural-language input, not for human-readable navigation. By 2028, 20% of storefront interactions are projected to shift to machine customers.
Operators
- Elena Verna — Agents are first-class product users; design for output reliability, not navigation. Agents are first-class product users; design for output reliability, not navigation.
- Aparna Chennapragada — Natural language is the interface; conversation flow is the design surface. Natural language is the interface; conversation flow is the design surface.
- Gartner — By 2028, AI agent "machine customers" will replace 20% of human-readable storefront interactions. By 2028, 20% of human-readable storefront interactions will be replaced by AI agent machine customers.
- Simon Willison — The dark factory: nobody reads the code, gated by a simulated QA swarm. The dark factory: nobody reads the code, gated by a simulated QA swarm — the production analog (agents producing for agents).
Variation
- Verna scopes it to product UX.
- Chennapragada scopes it to interface paradigm.
- Gartner provides the macro forecast.
- Willison provides the production analog (agents producing artifacts for other agents).
- Convergence: humans are no longer the only consumers of your product surface; design for the dual audience or get bypassed.
Implication
Audit your top user flows: which already have agent users, which are about to, which are still human-only? Add structured-output endpoints (clean APIs, MCP servers, schema'd responses) for agent consumption. Treat conversation flow design as a first-class craft. Forecast 20%+ machine-customer share for your category by 2028 and plan accordingly.
