I think the baseball example is different than fake photography. It's the photo you'd like to take if you could put your camera on the other side of the fence. The photo is an accurate representation of reality... it's just that the photographer (mom/dad) couldn't avoid the fence for whatever reason.

Now, if they took the flower from the next demo and said "Wish you were taking a picture of a different flower? Ta-da!!" Then yeah, that's not helpful, that's just fake.

I don't know about the leaving the campus portion...but it is unsettling. I keep searching for a Google email alternative, but can't find one.

I think the audience felt the same way - interestingly, that was the one demo they didn't cheer after, when he introduced it like that.

Definitely disconcerting, especially with people using data to do things like this: The Guardian: The great British Brexit robbery

I really think that people are taking it out of context. They are saying that the application you're using is aware of your location and can use contextual data.
