Of course, it is pretty impressive.

It isn’t magic. I think there we’ll often be surprised by the “hits,” but it’ll also get a lot of “misses.” A random photo in your back yard that doesn’t show the horizon will probably be a miss, right?

Meanwhile, lots of photos already include GPS coordinates… data you can strip out, but which is enabled by default for millions of people. Privacy, eh, never knew it I guess.

It's a fallacy to assume that one didn't have privacy merely because most people opted out of it due to personal reasons.
