My worry is that they are not thinking about how many ways this can go wrong. There are already iPhone apps that allows you to put on avatar and meet people in a 3D virtual world. According to DoJ these apps are haven for pedophiles. Nothing good happens in these apps. People with severe mental issues show up, try to hit up others and eventually end up destructing real lives. Initially, everything looks safe because it's all virtual, anonymous and no body is touching you but that sense of safety goes away very fast as you meet wierdos and divulge more and more information. Some of these apps have rules like no nudity but people finds out various ways to be provocative even more than if they were nude. As things are "virtual" everybody wants to push towards extremes of everything. These apps are places worse than Medusa's head.
Internet has good things and bad things but on these apps there is nothing good happens. I can imagine may be VR will be used to celebrate gradma's 90th birthday by her entire family virtually. But from what I can see, these will be about 1% to 2% of use cases. I don't think designers would intentionally encourage it but if you make meth legal, how many would actually use it for medical reasons?
