For me, you nailed it. Maybe how I feel on this will change over time, yet at the moment (and since the movie Her), I feel a deep unsettling, creeped out, disgusted feeling at hearing a computer pretend to be a human. I also have never used Siri or Alexa. At least with those, they sound robotic and not like a human. I watched a video of an interview with an AI Reed Hastings and had a similar creeped out feeling. It's almost as if I want a human to be a human and a computer to be a computer. I wonder if I would feel the same way if a dog started speaking to me in English and sounded like my deceased grandmother or a woman who I found very attractive. Or how I'd feel if this tech was used in videogames or something where I don't think it's real life. I don't really know how to put it into words, maybe just uncanny valley.
