There's a simpler explanation: no one's rolled them together because it's expensive and the current technology sucks. Second Life failed because it sucked. The Newton failed because it sucked. There's a pattern here: no one wants to buy shitty products. But that doesn't mean the concepts they're based on are inherently flawed.
There were other cars before the Model T and there were other smart phones before the iPhone. Technology takes a lot of stumbles before it reaches a marketable, consumable state. That can take decades or even centuries. Sometimes it just takes the right person or the right company to orchestrate it. We're not even close to being able to consider dismissing VR, or 3D printing, or artificial intelligence, or countless other technologies booed down by skeptics on the sidelines.
