I noticed the quest having inside-out tracking with cameras...point being that VR and AR are fuzzing a bit and it just might converge at some point as something that makes sense where you simply have more opacity or not depending on your app need. Then this type of argument is moot when say "oculus slim" comes out that looks like ready player one and is cool enough to wear everywhere and has a more contextual app model. (but i still think nueralink approach is the real future)
