Like, including what floor you happen to be on in an apartment building?
... uses your Wi-Fi, GPS and cell tower information to pinpoint exactly where you are
None of that contains any information about altitude. While it is technically possible to measure altitude as well and relay that, you cannot do so with enough anywhere close enough precision to get the exact floor of a building that you happen to be on if you live in an apartment building.
Land lines still rule for emergency services immediately knowing exactly where you are.
If the message is intercepted while it is being delivered, but is still otherwise delivered normally while a copy is saved elsewhere, I can see that being a problem, because the recipient gets no cues that interception is occurring. But that's not what I was talking about... the article talked about the problem of messages being intercepted and then *NOT* being delivered, which I would imagine is not going to be a serious problem.
No... just law enforcement.
I had once thought that this was because of a provincial court ruling that ordered them to do so, but I've been told since that this was not the case, so I can't say I'm entirely sure what would have happened if they had made any real attempt to argue against it. Perhaps they didn't feel it was worth the fight, particularly if they thought they would only lose anyways.
I fully agree with your main point, however.
It's the forced stereoscopy.... when you project different images into each eye, unless you are sitting only at certain spots in the movie theater, the angle that your eyes will have to converge to fuse the two images into a single 3d image in your visual cortex is unnatural with respect the distance that the visual differences between the two objects conveys to your brain about the apparently distance of what you are seeing.
Holograms would not have this effect, since where you are focusing on when you view a hologram is consistent with where the 3d image actually is supposed to be. The image appears as fully 3 dimensional as would looking at real physical objects on the other side of a pane of clear glass, or looking at things in a mirror.
But I imagine we're still some years away from real holographic movies being a thing.
When it is not necessary to make a decision, it is necessary not to make a decision.
