AI won't replace designers because it lacks taste and subjective opinion. Instead, as AI gets better at generating highly opinionated (though not perfect) designs, it will serve as a powerful exploration tool. This plants more flags in the option space, allowing human designers to react, curate, and push the most promising directions further, amplifying their strategic role.

AI tools democratize prototyping, but their true power is in rapidly exploring multiple ideas (divergence) and then testing and refining them (convergence). This dramatically accelerates the creative and validation process before significant engineering resources are committed.

AI's primary impact on design isn't just making it accessible. For experts, it's a tool to rapidly explore a vast space of creative possibilities. This allows them to sample far more options and apply their taste and intentionality to a much broader canvas than was previously possible.

Contrary to claims that "handoff is dead," designers at top companies use AI-generated prototypes as highly detailed specs. These interactive prototypes provide more information than static designs but are still handed off to developers for implementation, rather than being merged directly into production.

The goal isn't to build one perfect prototype quickly. The real strategic advantage of AI tools is the ability to generate three or four distinct variations of a feature in a short time. This allows teams to explore a wider solution space and make better decisions after hands-on testing.

AI's true productivity leverage is not just speed but enabling more attempts. A human might get one shot at a complex task, whereas an AI-assisted workflow allows for three or more "turns at the wheel." The critical human skill shifts from initial creation to rapid review and refinement of these iterations.

With AI, designers are no longer just guessing user intent to build static interfaces. Their new primary role is to facilitate the interaction between a user and the AI model, helping users communicate their intent, understand the model's response, and build a trusted relationship with the system.

For creative work like design, AI's true value isn't just accelerating tasks. It's enabling designers to explore a much wider option space, test more possibilities, and apply more craft to the final choice. Since design is non-deterministic, AI serves creative exploration more than simple speed.

Figma's CEO argues that while agentic coding systems are powerful, they risk being too linear. True product innovation requires exploring a wide option space through design, using systems and components to ensure a cohesive user journey. Relying solely on code generation can lead to a suboptimal product, even if it's built quickly.
