I don't understand why these Telescreen ( ok, teleblock ) technologies don't require voice print access control as default. Voice biometric is older than this cloud voice NLP tech. Also, it's amazing to me that human psychology and the zeigeist requires everyone flip out over Google Glass, but always on microphones linked to the Company, totally fine. Tolerated, in fact, behind the point of inconvenience. The other incongruous observation I want to add is voice is taking off in the home, but people using voice typing and control in public isn't as accepted. There's an essay in this somewhere.
