There used to be a time when you could impress your family by loading up Google Maps, finding a childhood memory, and zooming in until it became a sort of pixellated memory lane. Your mum and dad would be amazed, and you would be lauded because you showed them their old shed viewed from a satellite on the same thing they use to look up recipes.
I thought I was past that sort of technology-as-magic reaction, but since I tried out Google Earth VR on my Vive I’ve been shoving it on visitor’s faces ever since. It s magic.
