<h1 style="font-size: 22px; font-weight: normal;">The Second Wave of the Metaverse : Has the Metaverse Really Died?</h1>By 2022–2023, “metaverse” seemed like a fading buzzword. VRChat, Roblox, and Meta Horizon persisted, but public attention shifted to AI.In 2025, a new narrative emerges: Spatial Computing and AI World-Building are reviving the idea of immersive virtual worlds,but with far more automation and scalability.<h3 style="font-size: 22px; font-weight: normal;">What is Spatial Computing?</h3>Spatial Computing goes beyond VR/AR. It integrates real-world space and digital objects for natural interaction:<ul style="list-style: inside none; padding: 0px; margin: 0px;"><li style="list-style: inside none; padding: 0px; margin: 0px;"></li><li style="list-style: inside none; padding: 0px; margin: 0px;">Apple Vision Pro: Launch apps in 3D space, manipulate with hands</li><li style="list-style: inside none; padding: 0px; margin: 0px;">Meta Quest 4: Mixed-reality games and collaboration tools</li><li style="list-style: inside none; padding: 0px; margin: 0px;">Samsung XR Headset: MR device integrated with Google ecosystem</li></ul>The key idea: apps live in your physical space, not just on a screen.<h3 style="font-size: 22px; font-weight: normal;">What is AI World-Building?</h3>Traditional metaverse creation required months of modeling and coding. Now, AI can generate worlds instantly:<ul style="list-style: inside none; padding: 0px; margin: 0px;"><li style="list-style: inside none; padding: 0px; margin: 0px;"></li><li style="list-style: inside none;
