Startups are overwhelmingly focusing on rings for new AI wearables. This form factor is seen as ideal for discrete, dedicated use cases like health tracking and quick AI voice interactions, separating them from the general-purpose smartphone and suggesting a new, specialized device category is forming.

Despite access to state-of-the-art models, most ChatGPT users defaulted to older versions. The cognitive load of using a "model picker" and uncertainty about speed/quality trade-offs were bigger barriers than price. Automating this choice is key to driving mass adoption of advanced AI reasoning.

The true evolution of voice AI is not just adding voice commands to screen-based interfaces. It's about building agents so trustworthy they eliminate the need for screens for many tasks. This shift from hybrid voice/screen interaction to a screenless future is the next major leap in user modality.

Instead of visually-obstructive headsets or glasses, the most practical and widely adopted form of AR will be audio-based. The evolution of Apple's AirPods, integrated seamlessly with an iPhone's camera and AI, will provide contextual information without the social and physical friction of wearing a device on your face.

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 future of AI isn't just in the cloud. Personal devices, like Apple's future Macs, will run sophisticated LLMs locally. This enables hyper-personalized, private AI that can index and interact with your local files, photos, and emails without sending sensitive data to third-party servers, fundamentally changing the user experience.

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.
