The ultimate winner in the AI race may not be the most advanced model, but the most seamless, low-friction user interface. Since most queries are simple, the battle is shifting to hardware that is 'closest to the person's face,' like glasses or ambient devices, where distribution is king.

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.

AI will operate our computers, making our primary role monitoring. This frees people from desks, accelerating the need for a mobile interface like AR glasses to observe AI and bring work into the real world, transforming productivity.

The primary interface for managing AI agents won't be simple chat, but sophisticated IDE-like environments for all knowledge workers. This paradigm of "macro delegation, micro-steering" will create new software categories like the "accountant IDE" or "lawyer IDE" for orchestrating complex AI work.

As AI moves into collaborative 'multiplayer mode,' its user interface will evolve into a command center. This UI will explicitly separate tasks agents can execute autonomously from those requiring human intervention, which are flagged for review. This shifts the user's role from performing tasks to overseeing and approving AI's work.

The next human-computer interface will be AI-driven, likely through smart glasses. Meta is the only company with the full vertical stack to dominate this shift: cutting-edge hardware (glasses), advanced models, massive capital, and world-class recommendation engines to deliver content, potentially leapfrogging Apple and Google.

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.

While phones are single-app devices, augmented reality glasses can replicate a multi-monitor desktop experience on the go. This "infinite workstation" for multitasking is a powerful, under-discussed utility that could be a primary driver for AR adoption.

Spiegel articulates a strong philosophical stance against Virtual Reality, arguing it isolates people from the real world. Snap's strategy is to invest exclusively in Augmented Reality technologies like Spectacles that aim to enhance in-person human connection rather than replace it with a virtual one.
