The article kind of seems to contradict itself -- she starts out talking about how the Rift and the Vive are super expensive and will only be available to a small subset of the population and then she ends by telling you to get started with the $15 Google Cardboard and a bunch of free tools. In fact I don't really know what the takeaway of this whole article was, about half of it just talks about how exciting the potential of VR is and then talks about whatever project she worked on.
