As humanity edges toward immersive digital worlds that mirror physical reality, the infrastructure beneath them must reconcile two ancient tensions: speed and endurance. Researchers have now demonstrated that a distributed artificial intelligence system, operating across terahertz wireless networks, can manage the computational and energetic demands of Metaverse applications in real time — reducing energy use by up to 41 percent and holding latency within the narrow window that keeps illusion intact. The work suggests that the gap between the Metaverse as aspiration and the Metaverse as lived
