No human will ever enjoy the feeling of a giant block on their face. Even if the quest was 100x higher res it will never be "default" since it limits peripheral awareness, motion, causes eye strain.

I get Zuck's philosphy on upping the human-computer paradigm to the natural next step but imo horizontal screens at a comfortable 1-10 feet from your eyes will remain unchallenged until seamless brain controlled holograms become a thing.
