The last question is interesting. Our eyes create an image with ~ 1 Gigapixel resolution at frame-rate equivalent > 120 Hz.
For real VR/AR, 5G is not fast enough, would have to work in the THz regime for wireless (wow, nature has a huge bandwidth requirement...). Interesting thing about THz is that most electronic materials breakdown and stop working.
The actual resolution of the human eye is much smaller than that and a lot of our perception is based on interpolation. It's pretty interesting to read up on this.
