"It allows for virtual tourism, the ability to explore Notre Dame or The Louvre or the Great Wall of China in a very compelling way - remotely."
To me, the most compelling way to see the Great Wall of China is to hop on a plane and take a long holiday. Maybe stop by Hong Kong and pick up some cheap tech. What's the point of seeing it from my livingroom? I can already do that via Google Image Search - fine, not so 3D, but it's the same thing. You're either there or you're not. There's no such thing as "virtual tourism" until you have robots with cameras that you can link to a VR suite and control, and even then I'm not sure it counts as "tourism". This is impressive, and yet at the same time, silly.
