> It can already convince the brain so throughly of what is being seen, that people are given vertigo….Others get motion sickness from being on a ship at sea.

That's not because of technology, that's because humans.

I get vertigo playing Descent on a flat screen.

You don't need immersion-level resolution to create vertigo, so vertigo is no indication that your resolution is good enough. And 1440x1600 is absolutely not good enough. Far from it.
