What can 3d interfaces do better that they replace 2D interfaces as the preferred medium for digital activity? Are those benefits worth the additional costs of producing, distributing, and interacting with 3D content? The argument that VR/AR is a boon restrained only by current technological ability seems to be incomplete. Rather, could there be some other economic, cultural, and practical factors which make VR/AR unappetizing outside its niche use cases? (EG, why did 3D television "fail" despite being available for a long time?) I don't personally believe that 3D will eventually replace 2D because I know I wouldn't want to develop 3D content when 2D is a chore already. If 3D will replace 2D in some point in the future there should be a greater emphasis on developing technologies to make creating 3D content as easy (if not easier) as creating 2D content.
