I think it's better to compare VR to Ham Radio in that there's a hobbyist or niche interest but not enough to spawn a mainstream adoption of the technology. Even AR I think has a similar problem since it's all about making a market where no real demand exists. VR is cool in my opinion but it really isn't something I can see even my nieces and nephew using beyond once or twice in their lives. The games they play tend to be focused on the relaxation they bring with the ability to just lounge in the living room which VR breaks from that format of leisure. VR seems to take effort to consume and if you don't find that kind of effort relaxing then you're not likely to do it for a pass time or hobby. Frankly, I think too many in Silicon Valley assume their interests mirror the interests of non-Valley and non-technically-minded people.
