XR Native Markup
I've had this idea for a very fun personal project. I want to make a new XR native markup language for describing scenes. Right now, it seems like XR isn't suited for most consumers because the only things actually worth doing there (cost-wise and time-wise) are gaming and some very niche professional training simulations. Most websites in VR look the same. In the age of spatial computing, 2D websites on a flat browser window won't cut it. I envision a VR experience in which UI on websites is built from the ground up to be written for 3D/VR. Currently, doing so is done by embedding javascript in normal HTML. I think HTML for VR should be much simpler—more like how it felt to write your very first website.
