> Regarding sickness: Doesn't stop mountaineers. Doesn't stop sailors. Humans adapt remarkably. I'm a mountaineer. Feeling ill at altitude isn't the same as motion sickness. People can die of HAPE - it's not something to brush off and say, "humans can adapt". The great majority don't at high altitude. That's why you see tourists on Everest with oxygen masks and dexamethasone in tow. It's not to be a little more comfortable, it's to be a little less likely to be dead. I also get motion sickness for weeks on end. Trying VR isn't exactly appealing to me, but I'm pretty sure I'm not going to die from it. I grew up on a sailboat - other than feeling weird for the first coupla hours after sailing, it wasn't a big deal. People are complicated, I guess.
