We just bought a couple of Echo Dots for the house and this is the first time my sister is using it. She says please and thank you to Alexa. When Alexa fails to find an answer to her query, she gets angry at her and rudely tells it to "shut up". Then apologises for her behavior. She tries to have contextual conversations with it. It seems like the line between a human and a machine is getting blurred for some people. What implications do you think this is it going to have on the next generation who grow up in a house with these devices?
