VR optics explained
Very interesting subject about which I knew little to nothing before watching the video.
For me, the last bit was the most important: the next 10 years of VR technology.
It doesn’t sound like headsets in the lower price category will see huge benefits any time soon. Expensive, high-end units however could see substantial improvements in that time frame.
Looking a bit further into the future… afraid I won’t be around for the rollout of “direct brain sensory cortexes stimulators” to the general public 
I think the most important tech in VR is asking Ai chip to produce the image of 2nd eye, instead of asking GPU to render two 3D world at the same time.
