1. Enough AI copilots, we need AI HUDs Total comment counts : 85 Summary Mark Weiser’s 1992 critique of AI design highlights the limitations of the “copilot” metaphor for AI, advocating instead for a focus on “invisible computers” that enhance human awareness. He contrasts the copilot model, which actively assists, with the concept of a Head-Up Display (HUD) that seamlessly integrates information into the user’s perception. Modern examples include spellcheck and custom debugging tools that augment human understanding without direct interaction....
