The article can be read both ways (also saying that VR is a fad long term).
The fact that it admits that VR is "disruptive" and has "many uses" doesn't mean it's not a fad when it comes to the general population. Something that's trully useful in a lab or educational setting can still be a useless fad gadget people have bought for personal use.
That's still an assessment of VR as it currently exists in current products. It's ludicrous to argue that VR as a whole (immersing someone in a believable, manufactured reality) is a fad. IMAX movies, video games, Second Life, and even role-playing are poor versions of VR that demonstrate that humans are striving toward it.
> No doubt, VR will have many uses. It's fairly disruptive
The article is really arguing that this particular generation of VR hardware is a fad, not that VR itself won't become mainstream.
