While its true that the future IS bright for both Virtual Reality and Augmented Reality, we should also keep in mind the risks. One needs look no farther than the power that social media sites, such as Facebook, have to monitor, influence and shape perception already to understand the potential dangers of this technology. Not only will Facebook (through its VR tech Oculus Rift) have the power to create a profile of you through your messages, contacts, photos, and user activity (like they do today), but they will now have access to your biometric information, physical movements, the layout of your homes, and everything you see and experience through the VR interface - not to mention direct access to your very brainwaves. They will also have the power to influence you through the immersive VR experience that they will fully control. Given how deep their influence is now, its frightening to think about how total their (and, by extension, other actors like the government) control could (will?) be once VR becomes ubiquitous.

Certainly we should all be excited about these emerging technologies, but we should keep in mind that the potential for negative outcomes is just as real as the potential for positive ones.
