david: that was caitlin reporting. joining us now, david kirkpatrick. fitting you have gone up multimedia on us. we just saw you on tape in the piece. now we have you buy skype. on this story about the echo and the artificial intelligence in the home. how transformational could this be? transformational. one thing i think the story did not fully explain as that the something called the dot, a $50 version of the echo, which is possibly what sold like hotcakes over the holidays, even though amazon does not give us the numbers. i was in florida at my father's nursing home and all of the nurses were talking about getting echoes for christmas. this is a huge product.
