This article strikes me as saying something akin to "Cellular phones are a stupid idea and will never take off. They're heavy, the size of a brick, and you can only use them in the few areas where there are towers nearby." Well yeah, if we were perpetually stuck in 1985 sure, but fortunately we're not.
I'd argue that the current generation of VR (Rift/Vive/Gear/PS4/etc) is already multiple orders of magnitude more successful than past attempts, and, to continue the cell phone analogy, we're essentially in 1985 right now.
