Maybe I can write more on near-far and signaling in another book. One thing at a time. Most of the things that make our physical world luxurious or impoverished have little to do with the cost of simulating them. A dirty smelly hut is just as expensive to simulate as a vast mansion. Yes, they might spend 0.1% more relative to brain computing costs on computing VR if that increases work productivity by more than 0.1%.
A mansion will have dozens or hundreds of rooms; how can equally difficult rooms be just as expensive to simulate when there are hundreds more rooms in one scenario than another?
If the em is only in one room at a time, only one room must be simulated in detail at any one time.
The future will have little winding passages constructed to prevent line-of-sight from one room to another?
Deus Ex was righter than they knew.
The rooms will still need to be designed and available somewhere; even AAA games can't get away with indefinitely big canned environments no matter how many paging or zoning tricks they use to reduce the immediate rendering costs.
