I absolutely hate to use voice-controlled assistants. Not because they are annoyingly dumb, not because they can only be good in areas their developers prepared them, but because this way of communication is much slower and absolutely not private, at all. Maybe most of the population currently is living lonely, but I have family and I'm not ready to speak out my web surfing to them. Even more stupid it would be to do in office or train, plane. Only good place for voice-controlled assistants is a car, I think. And a spaceship.
