LOL. No danger of that ever happening in my place, can't imagine wanting to talk to a device, I don't even use that feature in my phone....seems silly to talk to other than a real person. I'm old, tho.
I don't have conversations with Alexa, "she" is way too dumb for that!
I tell ask her for the news and weather in my bathroom when I wake up.
In the living room, I ask her to shuffle my music.
In the kitchen, I'll ask her to set a timer (for when to flip the steaks, etc) as I'm stepping out the door with plate and tongs in hand.
All of them get asked to play music depending on where I am. Also, excellent with music trivia such "tell me about the band, Grass Roots. (it reads the introductory section from wikipedia).
Really, there is no way to have a decent conversation with Alexa, but if you think of her as a dumb version of the computer from Star Trek, that is where the Dot is worthy. I would not buy an Echo again. Using the Dot with powered speakers gets you a fine "voice command" music system.
