That would be cool, I'd like that too. Problem is, this only exists in a) marketing material, b) sci-fi movies, and c) if you do everything yourself. In the IoT industry, competition itself is ruining most of the "smart" devices' utility. They won't be useful until apps, hubs and devices are completely independent and commoditized, and you could argue they might not be useful to regulars even then (cue the long discussion on why stable society is incompatible with interesting life).
