There is a wide spectrum between sending 3d models to web pages and The Matrix. There are 2 things going on here: 1) making gpu more accessible to the www 2) the headsets/glasses hardware. Everyone seems caught up on 2 when I think the more important thing is 1. I hope the future is to do 3d dev in www by default rather than depending on exporting a unity/unreal/etc thing. I can see www replacing a lot desktop 3d content creation apps if that came to pass.
