The folks coming from film/video to VR speak of it as a new medium. Describing it as analogous to the early days of cinema, before the now familiar cinematic idioms had been developed. The folks working on WebVR say similar things wrt web idioms. And, to a perhaps lesser extent, gamedevs do too (motion, controls, showing state, haptics, accessing inventory, etc). And almost none of these communities were active in past VR waves.

So perhaps you and the article are using the phrase "new medium" differently.
