And, of course, it's his level of genius. And it's awesome. But, hell, aren't we scared yet?
Given everything we now know about the end of privacy, the fact that the NSA have back-doors to all our mainstream social software that Google are legally prevented from telling us about? And that Google are putting always-on cameras onto everyone's face?
Is the thing that we are really missing the ability to have millimetre accurate models of all the geometry (and therefore, via recognition algorithms, inventories of all the objects), in every room we enter? Collected automatically? And potentially streamed to Google's servers? Do I want to have someone walk into my room and immediately start telling Google / the NSA everything I have in it?
Sure, it's going to make amazingly competent robots, though.
