What weird funny scary stories do you have from chatroulette?
JH: That was so weird. Let's see if we can get a sequel tomorrow, or we can get something today. JH: (V.O.) You know, maybe next time we can do a live demo. Alright, we're done here. It's been great. I'm kind of jaded now, kind of worn down. But I'll come back tomorrow and do it again, and again and again and again. You know, just have to be patient. You can't force anything. I promise. You can't force anything. But you can use the platform to your advantage.
JH: So next time, what I want to talk about is the next frontier -- artificial intelligence, specifically, specifically neural networks. And in the meantime, how about a quiet day, how about a quiet night?
JH: That was amazing.
JH: So now, I'm going to talk about the last frontier -- outer space. And out of curiosity, what's the law of universal gravitation?
UR: The law of universal gravitation is the stuff of gyroscopes.
JH: And what is the law of conservation of momentum?
UR: The law of conservation of momentum is the stuff of ... sorry.
JH: I didn't know that.
JH: So the stuff of modern physics -- I'm going to just come right out and say it -- the stuff of modern physics is nothing but math, is it not?
JH: So what is the stuff of outer space, is it not the stuff of outer space?
UR: Yes, it is. Absolutely.
JH: Now, was there ever a probe that you didn't want the rest of the human race to go on to?
UR: Well, the one thing about this question -- well, I didn't ask it -- is where's the sample? The sample is in the question. The sample is what you're going to use it for. And the thing about human curiosity is that we want to know where the human sample is. So for that to happen, we're going to need to know the answer to this provocative but ultimately basic butchers' dilemma: Where's the hot pie coming from?
JH: OK. Well, Dr. Urmson, I want to play for you a video that you shot while you were shooting the Curiosity rover. So this is a 30-second clip.
UR: So this is ... (Cheers) So this is the stereo image. The rover is pointing down at
