I think you severely underestimate the amount of serious work put into all these "tech properties" (I'm guessing you mean Facebook/Dropbox) by very experienced, in-demand engineers.
VR and AR both need just one hit application. What would be a hit application?
1) It should just work, with no annoying aspects. Should be completely intuitive and engaging/fun
2) People want to use it on a regular basis. For example people play games for hours at a time on a regular basis, or use an app every day multiple times a day. Not just a "use it for 10 mins, think it's cool but never use it again" app
