Very excited to see this, my ongoing prediction is that the metaverse will be WebXR based. No 30% cut from walled gardens, and sites can evolve from static, 2D flat experiences to immersive ones. Of course, apps will work day one on any headset in a platform-agnostic manner. And for the spark, just wait until the Apple headset ships with WebXR and WebGPU supported by default....

Also, my team are currently working on bringing Unreal Engine to WebXR.
