I heard this and frankly wanted to puke. The gratuitous um, uh, uh huh's and the like. I don't feel comfortable with machines imitating humans or the deception involved in this sort of human/a.i. interaction.
I thought about a David Bowie concert I attended in the early 1980's, the Glass Spider tour. Bowie pulls an unsuspecting woman out of the crowd and dances with her, somewhere along the line we all realize that we have been played.
I hate getting played. Or manipulated. By humans or machines.
