That's very true, I think there's a window of opportunity when a new device/technology becomes mainstream before it becomes commoditized/cornered by a few big players : thinking of the web, then mobile, now the app stores are saturated and very few people can make money from them. VR might be the next wave (although plenty of false starts in that space).
