Agreed with all of what you said. I'd like to add another point. The article basically only focuses on the gaming aspect of VR. But there is enormous potential in business/industry applications.
The focus now is primarily on VR systems as gaming platforms, but once people catch on the near limitless potential it has to revolutionize certain industries (thinking about design, engineering, ...) the interest in this technology will skyrocket. Just pick any topic whatsoever and start fantasizing about ways VR can improve on it, you are guaranteed to think of something.
So yeah, I think the VR developers kinda made a mistake by advertising it as a gaming platform, kinda shoving themselves into a box. The public perception is now skewed to see VR in a gaming context only. If we can get past that in-the-box thinking regarding this technology, it will definitely be here to stay this time.
