Mark Weiser’s 1992 talk critiques the metaphor of "copilot" as a representation of AI, arguing against the notion of AI agents that interact directly with users. He contrasts this with the idea of creating systems that seamlessly integrate with human abilities, advocating for an “invisible computer” that enhances human awareness without demanding attention. Weiser’s vision is illustrated through the use of a Head-Up Display (HUD) in airplanes, which provides critical information without interrupting the pilot’s focus. He
