I think it can open up a sort of travel for the majority of people in the world who may be able to get a mobile device and a cheap VR headset but who would find it difficult to impossible to actually travel to most places. I also think that VR tours will be an awesome way for children to learn both Geography and Social Studies in whole new ways. I think two way VR video (with interpretation capability) will change the world by bringing down the national, religious and linguistic barriers that separate us now.
