When I started my career 3G was the hot topic, and every investor kept asking 'what's the killer app for 3G?' It turned out that the killer app for having the internet in your pocket was, well, having the internet in your pocket. But with each of those, we knew what to build next, and with VR we don't. That tells me that VR has a place in the future. It just doesn’t tell me what kind of place.
