My point is not about whether or not it's possible because just about anything can be done eventually. It's simply a case of what is more likely: 1) Bleeding edge algorithms that can not only separate multiple speakers in parallel on a small device, but also transcode them and track their identities over periods of time and report back. 2) Alexa does exactly what it says on the bin because Amazon already extrapolated everything they need to know about you (including whether you have a teenage daughter who is pregnant[1]) from your last 3 text searches. Also see this relevant comic: https://xkcd.com/538/ https://xkcd.com/538/ Now I may sound defeatist but this is not my intention. Like I said you should stay vigilant, but this article is barking up the wrong tree and may in fact distract from the real dangers in mass surveillance and tracking. Those dangers are far more primitive, yet effective, than you might think. -- [1] https://www.forbes.com/sites/kashmirhill/2012/02/16/how-target-figured-out-a-teen-girl-was-pregnant-before-her-father-did/#7359c58a6668 https://www.forbes.com/sites/kashmirhill/2012/02/16/how-targ...
