But what would the day-to-day applications of this be? I mean, if you really needed a photo of a side of a house that is now torn down, or if you needed "virtual" access to an unmapped/photographed area, then sure. But the article is talking as if this is going to replace cameras for all scenarios, specially recreational (as that's the only thing focused on in the article).
I see no exciting uses of this technology for recreational purposes. You wouldn't be able to take a photograph of the Library of Alexandria because that existed before we started gathering the data. And taking synthesized photos of your trips would make no sense, why would you even take the picture at all in that case?
My point is that it's a bad article. Technology is cool though.
