1) How much harder and stranger will it be to do VR graphics programming?
2) Can we predict when we will be able to replicate real world in a graphics application?
3) AI has a end goal of achieving singularity. What is the ultimate goal of a graphics programmer? And how much closer are we to the goal?
Replicating the real world is still very far off, but there is an estimate where the resolution offered by the screen matches the average density of receptors in the eye. I don't recall exact numbers, but I seem to remember Michael Abrash having said something about it. Probably somewhere in the range of 8k displays per eye.
What's cool is that mobile manufacturers have already committed to creating screens capable of much higher-density screens than current technology. The VR space was a bit nervous regarding display technology due to the diminishing returns of higher-resolution screens but recent announcement makes hi-resolution VR not only possible but likely regardless of the success of individual VR companies.
