ashlee: he is mark sagar, a computer scientist at the university of auckland. e famous for building super detailed simulations of the human body, and ended up winning a couple oscars for his work on films like "avatar" and "king kong." these days, mark is -- how to put this? trying to reverse engineer the human brain. he has built a series of simulations around how the human phase moves, our emotions, and how neurons fire. mark: we are trying to build a computer that has experiences, can imagine, and basically has its own existence, in a way. now what we are going to do is i am going to run baby x. what we are building here is a computer that can learn. so, this is baby. she is sort of looking at us and hearing us. if i make a loud noise, she can get a fright. this is what she can see. she can see my face here. so she is not copying my smile. she is responding to me. now this is little baby's first book. you can pick up the page and show her something. you have to get her attention. ashlee: hi, baby. what do you see? what's this? >> puppy. ashlee: very good. wha
