I have an Echo in the kitchen, which I love. And other devices in the house that respond to "Ok, Google" or "Hey Siri!". The conscious trade-off in my family is that voice control is useful, natural, and fun versus a somewhat low probability that amazon/google/apple are recording everything we say. The latter would be as catastrophic for those companies as the VW emissions scandal. Which of course happened, so it's just a low probability, not zero. Companies do dumb things and break the law all the time. The answer is to make sure that sensible laws, vigorously enforced, are in place. I don't see a huge difference between an Echo and the camera/microphone in my laptop - they both could be listening all the time, and there's a certain level of trust that smarter people than me have checked and found nothing. Can anyone wearing a tin-foil hat in this thread point to credible evidence otherwise? That would be enough to make me change my mind, but I doubt there's anything I could say that would change yours.
