As users increasingly interact with voice-first AI assistants, the traditional digital advertising model faces a major disruption. With no screen to display ads, companies that rely on visual ad revenue, like Google, must find new ways to monetize these interactions without ruining the user experience.

Figma CEO Dylan Field predicts we will look back at current text prompting for AI as a primitive, command-line interface, similar to MS-DOS. The next major opportunity is to create intuitive, use-case-specific interfaces—like a compass for AI's latent space—that allow for more precise control beyond text.

The best UI for an AI tool is a direct function of the underlying model's power. A more capable model unlocks more autonomous 'form factors.' For example, the sudden rise of CLI agents was only possible once models like Claude 3 became capable enough to reliably handle multi-step tasks.

The evolution from simple voice assistants to 'omni intelligence' marks a critical shift where AI not only understands commands but can also take direct action through connected software and hardware. This capability, seen in new smart home and automotive applications, will embed intelligent automation into our physical environments.

The magic of ChatGPT's voice mode in a car is that it feels like another person in the conversation. Conversely, Meta's AI glasses failed when translating a menu because they acted like a screen reader, ignoring the human context of how people actually read menus. Context is everything for voice.

The next frontier for conversational AI is not just better text, but "Generative UI"—the ability to respond with interactive components. Instead of describing the weather, an AI can present a weather widget, merging the flexibility of chat with the richness of a graphical interface.

The next user interface paradigm is delegation, not direct manipulation. Humans will communicate with AI agents via voice, instructing them to perform complex tasks on computers. This will shift daily work from hours of clicking and typing to zero, fundamentally changing our relationship with technology.

The most valuable use of voice AI is moving beyond reactive customer support (e.g., refunds) to proactive engagement. For example, an agent on an e-commerce site can now actively help users discover products, navigate, and check out. This reframes customer support from a cost center to a core part of the revenue-generating user experience.

Despite the focus on text interfaces, voice is the most effective entry point for AI into the enterprise. Because every company already has voice-based workflows (phone calls), AI voice agents can be inserted seamlessly to automate tasks. This use case is scaling faster than passive "scribe" tools.
