It's worth noting that the folks in the article reporting simulator sickness and long term disorientation are pilots, meaning they have been screened and selected for their endurance and resistance to motion sickness. On top of that, the symptoms they are reporting go well beyond seasickness. Have a look at rowanH's comment in this thread for a better idea of the effects we are talking about.

I'd certainly agree that the brain can adjust to using VR, but at what cost? If using VR means losing your depth perception and sense of balance, so that you are walking around bumping into things (or worse driving), then it's probably not going to be worth it for many people, despite how fun it might be.
