- 0:01Speaker 1: Welcome to stuff you should know from how Stuff Works
- 0:04Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh Clark.
- 0:14Speaker 1: There's Charles w Chuck Bryant, there's Jerry over there. I'm
- 0:18Speaker 1: just gonna come out and tell everybody making fun of
- 0:20Speaker 1: me for some weird reason, vaguely weird ways. But I'm
- 0:26Speaker 1: all right. So, Chuck, I have a story for you.
- 0:29Speaker 1: I'm gonna take us back to the seventeen seventies and
- 0:33Speaker 1: the swinging town of Vienna, not Virginia, not Vanna Georgia,
- 0:40Speaker 1: but you know that's how they pronounce it, right, Vanna
- 0:43Speaker 1: Yanna sausages, right, Vienna, Austria. You ever been there? Vienna, Austria. No,
- 0:49Speaker 1: I've been to Brussels. That was pretty close. Vienna's lovely,
- 0:53Speaker 1: I'm sure. I think it's a lot like Brussels. Very clean,
- 0:57Speaker 1: lovely town. I just remember to be very clean, Yeah,
- 1:01Speaker 1: very clean, gorgeous architecture, weird little angled side streets. They're
- 1:06Speaker 1: very narrow, very pretty tone. So we're in Vienna and
- 1:10Speaker 1: there is a dude skulking about going to the royal
- 1:15Speaker 1: Palace in Vienna. His name is Wolfgang von Kimberlin, and
- 1:21Speaker 1: he's an inventor. He's an engineer. He's a pretty sharp dude,
- 1:25Speaker 1: and he's got with him what would come to be
- 1:27Speaker 1: known as the Turk, but he called it the mechanical
- 1:31Speaker 1: Turk or the automaton chess player, and that's what it was.
- 1:36Speaker 1: It was a It was a wooden figure that moved mechanically,
- 1:41Speaker 1: seated at a cabinet and on top of the cabinet
- 1:44Speaker 1: was a chessboard. And when he brought it out to
- 1:47Speaker 1: show to the Royal Court, he would um, it was cool,
- 1:53Speaker 1: kind of but nothing they hadn't seen before, because automata
- 1:57Speaker 1: was kind of a hip thing by that. Yeah, people
- 2:01Speaker 1: loved building these engineering these automatum machines to do various things.
- 2:08Speaker 1: And people are just knocked out by the fact that,
- 2:11Speaker 1: you know, you hide these gears and levers behind wood
- 2:15Speaker 1: or a cloth and it looks as though there's a
- 2:18Speaker 1: real well I'm not real, but you know what I
- 2:19Speaker 1: mean is that it's like a real machine. Yeah, but not.
- 2:23Speaker 1: They weren't fooled anything like is that a real man?
- 2:26Speaker 1: It was, but it was for their time. It was
- 2:29Speaker 1: so advanced looking that it's like us seeing ex machina
- 2:33Speaker 1: in the movie theater that makes sense. Yeah, no, it
- 2:37Speaker 1: does make sense. But imagine seeing like x Makina and
- 2:39Speaker 1: being like I've seen this before. This isn't anything special, okay. Yeah,
- 2:44Speaker 1: and this thing, to be clear, look like a is
- 2:47Speaker 1: it Zoltar or Zoltan from Big Zoltar Sultan? I don't know,
- 2:53Speaker 1: it's one of those two, one of those two. Like this,
- 2:55Speaker 1: this guy's wearing a turban and it's in a glass
- 2:58Speaker 1: case like bust like you know, like a chest up thing. Yeah,
- 3:03Speaker 1: he's seated at this this cabinet, so there's no need
- 3:06Speaker 1: for legs or anything like that. Yeah. But the thing,
- 3:08Speaker 1: this is what was amazing about the Turk. He could
- 3:12Speaker 1: play chess, and he could play chess really well. So yeah,
- 3:16Speaker 1: he was like an automaton and he moved all herky
- 3:19Speaker 1: jerky or whatever. But he could play you in chess,
- 3:23Speaker 1: which was a huge, huge advance at the time. Like,
- 3:29Speaker 1: this is something that wouldn't come up again until the nineties,
- 3:33Speaker 1: more than two hundred years later. This thing, this automaton
- 3:37Speaker 1: could play a human being in chess and beat them. Well, yeah,
- 3:40Speaker 1: and it looked like when the game started, it would
- 3:42Speaker 1: look down at the chessboard and like cock his head
- 3:45Speaker 1: like m what should my first move be? And if
- 3:48Speaker 1: people I love this part, if people tried to cheat.
- 3:51Speaker 1: Apparently Napoleon tried to cheat this thing because this guy
- 3:55Speaker 1: he debuted at the Being's court, but then it, you know,
- 3:58Speaker 1: it went on a world tour. Yeah, and he was
- 4:01Speaker 1: even it was taken over by his successor to the
- 4:03Speaker 1: guy who toured with it. Even further, people went nuts
- 4:06Speaker 1: for this stuff. They did. They loved it because they
- 4:08Speaker 1: were like, this is crazy. I can't believe what I'm seeing.
- 4:10Speaker 1: Most people, though, were not taken in by it. There
- 4:13Speaker 1: like there's some trick here. But von kempel In and
- 4:16Speaker 1: the guy who came after him, I don't remember his name. Um,
- 4:19Speaker 1: they would they would demonstrate. You could open this cabinet
- 4:22Speaker 1: and you could see all the workings of the mechanical
- 4:25Speaker 1: turk inside. Right. So what I was saying is, if
- 4:29Speaker 1: this thing's since a cheater like Napoleon supposedly did it,
- 4:34Speaker 1: would you know Napoleon would move a piece out of
- 4:37Speaker 1: turner illegally or something. This dude, the turk Turk one
- 4:40Speaker 1: two would pick up the chess piece move it back
- 4:43Speaker 1: as if to say like, no, no, Napoleon, I see
- 4:45Speaker 1: what you're doing. And then if the person attempted to
- 4:47Speaker 1: move it again, I don't know how many times on
- 4:49Speaker 1: you two or three times, eventually it would just go
- 4:53Speaker 1: ah and wipe his hand across the board and knock
- 4:56Speaker 1: off all the pieces. Game over, which is pretty great,
- 5:00Speaker 1: A nice little feature, yeah it is. But it even
- 5:03Speaker 1: showed even more that this thing was thinking for itself.
- 5:07Speaker 1: That's the key here, right. Chess had been for a
- 5:10Speaker 1: very long time viewed as only something that a human
- 5:16Speaker 1: would be capable of because it took a human intellect.
- 5:19Speaker 1: And there was actually a guy in English um engineer,
- 5:23Speaker 1: I think he was a mechanical engineer. His name was
- 5:27Speaker 1: Robert Willis. He said that um chess was in quote
- 5:30Speaker 1: the province of intellect alone. So the idea that there
- 5:34Speaker 1: was this automaton playing chess blew people away. But again
- 5:38Speaker 1: people figured out, like, okay, there's something going on here.
- 5:41Speaker 1: We think that um von Kempelin is controlling this thing
- 5:44Speaker 1: remotely somehow, maybe using magnets or whatever. Other people hit
- 5:48Speaker 1: upon the idea that there was a small person inside
- 5:52Speaker 1: the cabinet who would hide when the cab when the
- 5:55Speaker 1: workings were shown, when the cabinet was open to show
- 5:57Speaker 1: the workings, and then when the cabin was closed again
- 6:00Speaker 1: and the mechanical turk started playing, the person had crawled
- 6:03Speaker 1: back out and it was actually controlling it. This seems
- 6:06Speaker 1: to be the case that there was a person controlling it,
- 6:09Speaker 1: but the idea that it was it was a machine
- 6:14Speaker 1: that could think and beat humans in chess, had like
- 6:17Speaker 1: kind of unsettling implications. Yeah, this author Philip Thickness, great name,
- 6:25Speaker 1: British author for sure, Philip Thickness. He uh, he said,
- 6:30Speaker 1: and you know, people like you said all those more
- 6:32Speaker 1: complicated explanations in this article you sent. Astuteley points out
- 6:37Speaker 1: that he followed Occam's razor and basically said, he's got
- 6:40Speaker 1: a little kid in there. He's got a little a
- 6:42Speaker 1: little Bobby Fisher in there that's really good at chess,
- 6:46Speaker 1: and that's what's going on. And other people speculated that other,
- 6:50Speaker 1: you know, little people might be in there, Um, just
- 6:52Speaker 1: adults who would fit in there. But then you know,
- 6:55Speaker 1: there's the explanation that he would open it up and
- 6:57Speaker 1: shine a candle around and say, you know nothing, just
- 7:00Speaker 1: see here everyone. Um, so what should we reveal the
- 7:07Speaker 1: real deal? Sure? I think I did already. Well, I
- 7:11Speaker 1: don't think you spelled it out is we'll spell it out.
- 7:14Speaker 1: There was a little person in there, Yeah, not just
- 7:16Speaker 1: one little person, but they would travel around and recruit people.
- 7:20Speaker 1: I guess people would get tired of being in there,
- 7:22Speaker 1: or they forget about them and they'd starve and have
- 7:24Speaker 1: to replace them. But it really was a trick. There
- 7:27Speaker 1: was a little person in there. They did the same
- 7:29Speaker 1: thing as like the magic acts. You know, when they
- 7:31Speaker 1: saw a person in half. It's that the lady just
- 7:35Speaker 1: gets into a tiny little ball in one section of
- 7:37Speaker 1: that box. But my thing is this, like, this is
- 7:40Speaker 1: not a satisfying explanation to me, Chuck, I think it's great.
- 7:43Speaker 1: How did the person keep up with the board above? Well?
- 7:48Speaker 1: I mean some I don't know if they ever proved
- 7:50Speaker 1: exactly how it was going. That's what I'm saying, Okay,
- 7:53Speaker 1: whether or not I think they that the zoltar or
- 7:57Speaker 1: I'm sorry, the turk was just hollowed out and you
- 8:01Speaker 1: you would just put your arms through the arm so
- 8:05Speaker 1: you would call up into the church. Yeah, you would
- 8:07Speaker 1: become the churk. When the churk would fuse, That's what
- 8:10Speaker 1: some people thought. I think that's what Edgar Allen Poe
- 8:13Speaker 1: thought too. He would Other people thought that there were
- 8:18Speaker 1: the the the little person was underneath in the cabinet
- 8:22Speaker 1: operating the turk with levers and stuff like that. Whether
- 8:24Speaker 1: it could have been a mirror or something, you know,
- 8:26Speaker 1: I guess a little telescopic mirror. That's what's getting me
- 8:29Speaker 1: is how would they keep up with the game. You
- 8:32Speaker 1: could keep track of the game, but how could you
- 8:34Speaker 1: see where the other person moved? You would know where
- 8:36Speaker 1: you moved, but you wouldn't be able to see where
- 8:38Speaker 1: the other person. That's what I don't get. Just mirrors
- 8:40Speaker 1: smoking mirrors maybe so. But the point is is it
- 8:43Speaker 1: was a fake. It was a fraud, but it raised
- 8:45Speaker 1: some really big questions about the idea of a machine
- 8:50Speaker 1: beating a person at something like chess. Yeah, and it
- 8:53Speaker 1: really peaked the mind of one Charles Babbage. He was
- 8:59Speaker 1: he was a kid or or young at least at
- 9:00Speaker 1: the time when he saw the turk in person, and
- 9:04Speaker 1: a few years afterward he began work on something called
- 9:06Speaker 1: the Difference Engine, which was a machine that he designed
- 9:11Speaker 1: too to calculate mathematics automatically. So at some point to
- 9:16Speaker 1: this is kind of maybe the beginnings of humans trying
- 9:20Speaker 1: to create a I well, yeah, with Babbage's differential machine
- 9:25Speaker 1: or difference machine, yeah, difference engine. But at the very least,
- 9:28Speaker 1: what this is is the first that I know of
- 9:31Speaker 1: example of man versus machine, even though it was really
- 9:35Speaker 1: man versus man because it was a man in the machine.
- 9:39Speaker 1: It was a fraud, yeah, but it was it. It
- 9:41Speaker 1: sparked that idea, It definitely did. And that's something that UM,
- 9:45Speaker 1: like chess in particular, has always been like this idea
- 9:49Speaker 1: of like, if you can teach a machine to play chess,
- 9:52Speaker 1: you really achieved a milestone. And there's been you know,
- 9:55Speaker 1: plenty of programs, was most notably Deep Blue, which we'll
- 10:00Speaker 1: talk about, but there's there's been this idea that like
- 10:04Speaker 1: part of AI is chess, teaching it to play chess.
- 10:09Speaker 1: But they, the people who develop a I never set
- 10:13Speaker 1: out to make a chess playing AI, just to make
- 10:16Speaker 1: a machine that can play chess. That's not the point.
- 10:19Speaker 1: Chess has always been this way to demonstrate the progress
- 10:23Speaker 1: of artificial intelligence because it's a complex game that you
- 10:27Speaker 1: can't just program it, like it almost has to learn. Uh, well,
- 10:32Speaker 1: it depends on how you come at it at first, right,
- 10:34Speaker 1: So initially they did try to program it Okay, there's
- 10:39Speaker 1: this for for from basically nineteen fifty two the about
- 10:44Speaker 1: the mid like about say sixty years right. That is
- 10:49Speaker 1: how they approached AI and chess is you figured out
- 10:53Speaker 1: how to break chess down and explain it to a computer. Now,
- 10:59Speaker 1: what if you could, ideally you would have this this
- 11:02Speaker 1: computer or this AI, this artificial intelligence UM be able
- 11:07Speaker 1: to think about the outcome of every possible every possible
- 11:12Speaker 1: outcome of a move before making it. That's just not possible.
- 11:15Speaker 1: It's still today we don't have computers that can do that, right,
- 11:19Speaker 1: So what you have to do is figure out how
- 11:20Speaker 1: to create shortcuts for the machine, give it best practices,
- 11:24Speaker 1: that kind of thing. And that was actually laid out
- 11:27Speaker 1: in by a guy named Claude Shannon, who is the
- 11:30Speaker 1: father of information theory. And he wrote a paper with
- 11:34Speaker 1: a pretty on the nose title called programming a Computer
- 11:37Speaker 1: for Playing Chess. And you have to say it like
- 11:40Speaker 1: that when you say the name, it's got a question
- 11:42Speaker 1: market in the end, right. But he laid out two
- 11:44Speaker 1: big things, um. One is creating a function of the
- 11:50Speaker 1: different moves, and then another one is called a mini max.
- 11:56Speaker 1: And if those were the two things that Shannon laid
- 11:58Speaker 1: out and they established about fifty or sixty years of
- 12:02Speaker 1: development in teaching an AI to play chess. Yeah, so
- 12:06Speaker 1: this evaluation function is just sort of the base, the
- 12:10Speaker 1: very basis of it all kind of where it starts,
- 12:12Speaker 1: which is you ev kind of give a number to
- 12:14Speaker 1: create a numerical evaluation based on the state of the
- 12:19Speaker 1: board at that moment, and assign a real number evaluation
- 12:24Speaker 1: to it. So, um, the highest number that you would
- 12:28Speaker 1: shoot for is obviously getting checkmate, getting a king and
- 12:33Speaker 1: checkmate right, right, So what you've just done now is
- 12:36Speaker 1: by assigning a number to a state like the pieces
- 12:40Speaker 1: on a board. Um, what you what you've done is
- 12:43Speaker 1: to say, like shoot for this number. The higher the number,
- 12:46Speaker 1: like you're going to give this a either rule. Now,
- 12:48Speaker 1: the higher the number, the more desirable that this move
- 12:52Speaker 1: that could lead to that higher number. Function. Evaluation function
- 12:56Speaker 1: is what you want to do, right, like capture the
- 12:58Speaker 1: night or capture the queen. Kept of the queen would
- 13:00Speaker 1: have a higher evaluation number, right exactly. So that's the function.
- 13:04Speaker 1: And there's another one called the mini max. Yeah, this
- 13:07Speaker 1: is pretty great where you want to minimize the maximum.
- 13:10Speaker 1: And this is another shortcut that they taught computers the
- 13:12Speaker 1: maximum loss, that is right. So what they what they
- 13:15Speaker 1: talk computers do is so you know, computer can look
- 13:19Speaker 1: through an entire game every possible outcome. But what you
- 13:24Speaker 1: there are computers that can look pretty far down the
- 13:27Speaker 1: line at every possible outcome. And what you can say is, okay, um,
- 13:33Speaker 1: you want to find the evaluation function that is the
- 13:36Speaker 1: worst case scenario, the maximum loss, and then find the
- 13:42Speaker 1: move that will minimize the possibility for that outcome. Yeah.
- 13:46Speaker 1: By and this is your only limited by your programming power,
- 13:49Speaker 1: but by looking not only at the state of the
- 13:51Speaker 1: board right now, but if I make this move and
- 13:54Speaker 1: I move the the pond to this spot, what are
- 13:57Speaker 1: the next like three moves possibly that could happen as
- 14:00Speaker 1: a result of this move. And you're only limited, like
- 14:03Speaker 1: I said, by programming power. So obviously, the more juice
- 14:07Speaker 1: you have, the more moves ahead that you can look exactly.
- 14:11Speaker 1: And then they just shy away from ones with the
- 14:14Speaker 1: higher function number or lower function number, depending on how
- 14:17Speaker 1: you've programmed it. But they they they're making these decisions
- 14:21Speaker 1: based on these rules, um. And then there's other things
- 14:23Speaker 1: you can do, like little shortcuts to say, if if A,
- 14:27Speaker 1: if A decision tree leads to a the other players
- 14:33Speaker 1: King being in checkmate. Don't even think about that move
- 14:36Speaker 1: any further, don't evaluate any longer, just abandon it because
- 14:39Speaker 1: we would never want to make that move, right. So
- 14:41Speaker 1: there's all the shortcuts you can do. And that's what
- 14:44Speaker 1: they did to teach computers. That's what Deep Blue did
- 14:47Speaker 1: when it beat Gary Kasparo. It was this huge, massive
- 14:51Speaker 1: computer that knew a lot of chess, a lot about chess.
- 14:56Speaker 1: It had a lot of rules, a lot of incredibly
- 14:59Speaker 1: intricate programming that was extremely sharp, and it actually wanted
- 15:04Speaker 1: became the first computer to beat an actual human chess
- 15:09Speaker 1: grand master in like regulation match play. Yeah. I mean,
- 15:13Speaker 1: and I don't think caspar Off gets enough credit for
- 15:16Speaker 1: like willing being willing to do this, because it was
- 15:20Speaker 1: a big deal for him to lose. It was in
- 15:23Speaker 1: this community and the AI community. It was sent shock waves,
- 15:27Speaker 1: and everyone that was alive remembers, even if you didn't
- 15:31Speaker 1: know anything about either, one remembers Deep Blue being all
- 15:34Speaker 1: over the news. It was a really big deal. And
- 15:36Speaker 1: Casperrof put his name on the line and lost. Yeah,
- 15:39Speaker 1: And I was wondering, Chuck, how how like you would
- 15:42Speaker 1: get somebody to do that. I'm sure the Mountain of Catch.
- 15:47Speaker 1: I guess that would probably be part of it. But
- 15:48Speaker 1: I mean, I don't know. I bet, I bet that's
- 15:52Speaker 1: out there. We just I just didn't look it up.
- 15:54Speaker 1: So um, that's possible. It's also possible that they said, look, man,
- 15:58Speaker 1: like this is chess, we're talking about what ever, But
- 16:00Speaker 1: really what you're doing is helping advance artificial intelligence because
- 16:05Speaker 1: we're not at we're not really trying ultimately to win
- 16:07Speaker 1: chess games. We're trying to cure cancer. Yeah, we're gonna
- 16:10Speaker 1: take your title because we're gonna beat you, or our
- 16:14Speaker 1: machine is gonna beat you. But even still, you're gonna
- 16:16Speaker 1: be helping with cancer. Think of the cancer Casparrow. That's
- 16:20Speaker 1: probably what they said. Should we take a break? Yeah? Uh, what?
- 16:23Speaker 1: Well should we tease our special guests? First? Is he okay?
- 16:27Speaker 1: I can smell him. I don't think we even said
- 16:29Speaker 1: we're gonna have a special guest. Later in the episode,
- 16:33Speaker 1: Mr Jonathan Strickling of tech stuff nice. It's just been
- 16:36Speaker 1: a long time since, like years since we had stricken.
- 16:38Speaker 1: The last time we had stricken was like two thousand
- 16:41Speaker 1: nine with the Necronomicon episode what is what where has
- 16:44Speaker 1: he been besides sitting in between this every day? It's
- 16:47Speaker 1: been a strickling drought is It's yes, the stricklands coming later.
- 16:50Speaker 1: But we're gonna come back after this and talk a
- 16:52Speaker 1: little bit more about man versus machine. Okay, dude, So
- 17:18Speaker 1: what we just described was how AI was taught to
- 17:22Speaker 1: play things like chess or to think like you take something,
- 17:26Speaker 1: you figure out how to break it down into little
- 17:29Speaker 1: rules and and and things that a computer can think of, right,
- 17:33Speaker 1: and then follow these kind of rules to to make
- 17:35Speaker 1: the best decision. That's how it used to be. The
- 17:39Speaker 1: way that it's done now that everybody's doing now is
- 17:43Speaker 1: where you are creating a machine that teaches itself. That
- 17:48Speaker 1: was the breakthrough. You may have noticed back in about
- 17:51Speaker 1: two all of a sudden, things like Siri and alexa
- 17:58Speaker 1: um got way better at what they are doing. They
- 18:02Speaker 1: got way less confused. You're a navigation app got a
- 18:07Speaker 1: lot better. And the reason why is because these these
- 18:10Speaker 1: this type, this new type of AI, this new type
- 18:12Speaker 1: of machine learning that can teach itself and learn on
- 18:17Speaker 1: its own, just hit the scene and they just started exploding.
- 18:20Speaker 1: And one of the things that they were first trained
- 18:22Speaker 1: on was games. Yeah, and it makes sense. Um. And
- 18:25Speaker 1: if you thought chess was complicated and difficult, when it
- 18:29Speaker 1: comes to these new AI s that they're teaching to
- 18:32Speaker 1: teach themselves game strategy, they said, we might as well
- 18:36Speaker 1: dive in to the Chinese strategic game Go because it
- 18:40Speaker 1: has been called the most complex game ever devised by humans.
- 18:45Speaker 1: And this was actually that was actually quote from Demi Hassabi,
- 18:51Speaker 1: neuroscientists and the founder of deep Mind, which was deep Mind.
- 18:57Speaker 1: They were purchased by Google or where they are always
- 19:00Speaker 1: part of Google. I don't know if they were a
- 19:02Speaker 1: spun off branch or where they were purchased, but it's
- 19:04Speaker 1: one of Google's AI outfits. Well, they're they're one of
- 19:08Speaker 1: the teams, yeah, that they are designing these new programs.
- 19:10Speaker 1: And to give you an idea of how complex Go is, uh,
- 19:14Speaker 1: it deals with a board with with different stones and
- 19:17Speaker 1: there are uh ten how do you even say that
- 19:22Speaker 1: tend to the hundred and seventy power So that means
- 19:25Speaker 1: a hundred and seventies zeros uh and take that number
- 19:28Speaker 1: and that's the number of possible configurations of a Go board. Right, So,
- 19:32Speaker 1: like you say, chess is very complex and complicated and
- 19:36Speaker 1: it's very difficult to master Go. And I've never played
- 19:40Speaker 1: Go of you now, so it's supposedly it's easy to learn, right,
- 19:44Speaker 1: but very complicated in its simplicity, right right, exactly, it's
- 19:47Speaker 1: extremely difficult to master. And there was a guy in
- 19:50Speaker 1: the late nineties, and I'm guessing that that he was
- 19:55Speaker 1: saying this after Deep Blue beat casper Off. Um. There
- 20:00Speaker 1: was an astrophysicists from Princeton. He said that it would
- 20:03Speaker 1: probably be a hundred years before a computer beats the
- 20:05Speaker 1: human at Go. To give you an idea of just
- 20:08Speaker 1: how complex Go is, that deeply would just be cast
- 20:12Speaker 1: prov And this guy is saying it will still be
- 20:14Speaker 1: a hundred years before any anyone gets beat at Go
- 20:17Speaker 1: by a computer. And he was someone who knew about
- 20:19Speaker 1: this stuff, who was an astrophysicist. He wasn't just some
- 20:22Speaker 1: schmoe at home and drunk in his recliner just making
- 20:26Speaker 1: asinine predictions. Um. So, And again we've we've said this before,
- 20:31Speaker 1: but I want to reiterate the people that, uh, I
- 20:35Speaker 1: think Alpha Go is the name of this program. The
- 20:37Speaker 1: people that created this a deep mind. They wanted to
- 20:40Speaker 1: stress that this is a problem solving program. We're just
- 20:45Speaker 1: teaching it this game at first, to to make it
- 20:48Speaker 1: learn and to see if it can get good at
- 20:50Speaker 1: what it does. But they said it is built with
- 20:54Speaker 1: the idea that any task that has a lot of
- 20:56Speaker 1: data that is unstructured, and you want to find patterns
- 20:59Speaker 1: in the data and then decide what to do right,
- 21:02Speaker 1: And that's kind of like what we're talking about. It's
- 21:04Speaker 1: it crunches down all these possible options aka data to
- 21:09Speaker 1: decide what move should I make right, and you can
- 21:12Speaker 1: apply that. Ideally, they're gonna apply this to Alzheimer's and
- 21:15Speaker 1: cancer and all sorts of things. Right. That's general general
- 21:18Speaker 1: purpose thinking, right, yeah, and thinking on the fly to
- 21:22Speaker 1: faced with novel stuff. So one of the reasons why
- 21:26Speaker 1: it's good to use games like chess or go or whatever.
- 21:29Speaker 1: Those are called perfect information games where both players or
- 21:33Speaker 1: anybody watching has all the information that's available on it,
- 21:37Speaker 1: there are definite rules their structure. It's a good proving ground.
- 21:41Speaker 1: But as we'll see, AI makers are getting further and
- 21:44Speaker 1: further away from those structure games as their AI becomes
- 21:48Speaker 1: more and more sophisticated, because the structure and the limitations
- 21:53Speaker 1: aren't necessarily needed anymore. Because these things are starting to
- 21:56Speaker 1: be able to think on their own in a very
- 21:58Speaker 1: generalized and even creative way. Yeah, it's really really interesting
- 22:05Speaker 1: the way that they're like you said um earlier and
- 22:08Speaker 1: before the break that we we don't have computers that
- 22:10Speaker 1: can run all the possibilities. So what they teach in
- 22:13Speaker 1: the case of AlphaGo, this program teaches itself by playing
- 22:17Speaker 1: itself in these in these games and go specifically, and
- 22:22Speaker 1: the more it plays itself, the more it learns, and
- 22:24Speaker 1: the more ability it has during a game to choose
- 22:29Speaker 1: a move by narrowing down possibilities. So instead of like, well,
- 22:33Speaker 1: there are twenty million different variations here, by playing itself,
- 22:37Speaker 1: it's able to say, well, in this scenario, there really
- 22:40Speaker 1: only fifty different moves that I could or should make.
- 22:44Speaker 1: Right or that's kind of a simplified way to say it.
- 22:46Speaker 1: But right, No, but it's true. But that's that's exactly right.
- 22:49Speaker 1: And what they're doing is basically the same thing that
- 22:51Speaker 1: a human does. It's and it's going back to its
- 22:54Speaker 1: memory banks, yeah, exact experience and saying well, I've I've
- 22:58Speaker 1: been faced with something like this before, and this is
- 23:00Speaker 1: what I used and it was successful. Forty out of
- 23:02Speaker 1: fifty times. I'll do this one. This is a pretty
- 23:05Speaker 1: reasonable move. That is what humans do. Yeah, not only
- 23:09Speaker 1: I mean, boy, we screwed up the chess episode, but
- 23:11Speaker 1: I get the idea that when you're a chess master,
- 23:14Speaker 1: you don't just think what do the numbers say and
- 23:16Speaker 1: what does the book say? But oh man, I did
- 23:19Speaker 1: this move that one time and it didn't go as
- 23:23Speaker 1: the book said. So that's now factored into my thinking, right,
- 23:27Speaker 1: except imagine being able to learn from scratch and get
- 23:32Speaker 1: to that point in eight days or eight hours. So
- 23:35Speaker 1: that Go team, the Alpha Go the first the first
- 23:39Speaker 1: iteration of Alpha Go. I think they started working on
- 23:41Speaker 1: it in two thousand fourteen and in two thousands sixteen,
- 23:45Speaker 1: at the end of two thousand and sixteen, they unleashed
- 23:47Speaker 1: it um secretly onto uh an Alpha Go website and
- 23:53Speaker 1: it started just wiping the floor with everybody. Everybody's like,
- 23:57Speaker 1: this thing is pretty good. Oh it's Alpha Go. Well,
- 23:59Speaker 1: here's this it. That was the end of two thousand
- 24:01Speaker 1: and sixteen. Okay, so chess had already come and gone.
- 24:05Speaker 1: Like by this point, you can download a program that's
- 24:08Speaker 1: like deep Blue, right, that was that's a great point. Yeah,
- 24:11Speaker 1: Like today the stuff you played chess with on your
- 24:15Speaker 1: laptop is even more advanced than Deep Blue was in
- 24:18Speaker 1: the nineties. And it's just on your laptop. Um, but
- 24:21Speaker 1: this is so, this is Go. This is the end
- 24:23Speaker 1: of two thousand and sixteen. The end of two thousand seventeen,
- 24:26Speaker 1: um Alpha Go was replaced with Alpha Go zero. It
- 24:32Speaker 1: learned what Alpha Go had taken two years or three
- 24:35Speaker 1: years to learn in forty days by teaching itself, and
- 24:41Speaker 1: it beat the master. And finally, in May of two
- 24:44Speaker 1: thousand seventeen, Alpha Go took on Key G, the highest
- 24:50Speaker 1: ranked Go player in the world. I don't know if
- 24:53Speaker 1: he or she still is. No Lisa A. Doll is
- 24:57Speaker 1: the current or was until Alpha alpha Go beat him. Man, yeah,
- 25:03Speaker 1: do they get knocked off in Alpha Go is the champion? Like,
- 25:05Speaker 1: that's that's not fair. I if it's match play and
- 25:10Speaker 1: the player, the human players accepted a challenge from the computer.
- 25:15Speaker 1: I don't see why it wouldn't be the world champions.
- 25:18Speaker 1: Or do they just now say on websites like human
- 25:22Speaker 1: champions maybe in italics with like a sneer maybe yeah? Interesting?
- 25:28Speaker 1: What do they call that wet wear? Like your brain,
- 25:32Speaker 1: your neurons and all that what instead of hardware, it's
- 25:35Speaker 1: wet wear. Oh, I don't know about that. I think
- 25:37Speaker 1: that's the term for it. What does that mean? Though?
- 25:39Speaker 1: It means like you're you have a substrate, right, you're intelligence.
- 25:43Speaker 1: You're intellect is based on your neurons and they're firing
- 25:47Speaker 1: all that stuff, and it's wet and squishy and meat.
- 25:50Speaker 1: And there's hardware that you can do the same thing on,
- 25:53Speaker 1: you can build intelligence on, but it's hardware, it's not
- 25:56Speaker 1: wet wear. Interesting, so it's probably it. It's the wet
- 26:00Speaker 1: champion versus the hardware champion. But wet wears italicized what
- 26:05Speaker 1: the sneer? Uh So where things really got interesting because
- 26:08Speaker 1: you were talking earlier about um, what what is it
- 26:12Speaker 1: with the chess and go? What are they called? What
- 26:13Speaker 1: kind of games? Perfect information games? Right? Then you think
- 26:19Speaker 1: And my first thought when you said that was well, yeah,
- 26:22Speaker 1: then then there's there's games like poker like Texas Hold Him,
- 26:26Speaker 1: where there are a set of rules. But poker is
- 26:29Speaker 1: not about the set of rules. It is about sitting
- 26:31Speaker 1: down in front of whatever five or six people and lying,
- 26:35Speaker 1: bluffing and getting away with it in your game face
- 26:39Speaker 1: being bluff Like there's so many human emotions and contextual
- 26:44Speaker 1: clues and and uh micro expressions and all these things,
- 26:49Speaker 1: like surely you could never ever teach a machine to
- 26:53Speaker 1: win at Texas Holding poker. Yeah, it'll be a hundred
- 26:56Speaker 1: years at least before that happens, I predict. No, they
- 27:00Speaker 1: did it, and more than one team has done it. Yeah.
- 27:04Speaker 1: I read um there was one from Carnegie Melon called
- 27:08Speaker 1: Liberatus Ai go melon heads, Yeah, go the Thornton Melons.
- 27:15Speaker 1: Uh yeah, I mean that's was. The University of Alberta
- 27:19Speaker 1: has one called deep Stack. That was the one I
- 27:21Speaker 1: read about. And it actually here's the thing, like if
- 27:24Speaker 1: you read the release on it, you're like, you don't
- 27:28Speaker 1: know how this thing works to you? Yeah, And I'm
- 27:31Speaker 1: pretty sure they don't fully get it because that's one
- 27:33Speaker 1: of the problems. Actually talked about this in the Existential
- 27:36Speaker 1: Risks series that's Scared that is to be released there, right,
- 27:40Speaker 1: that there is a there is a type of machine
- 27:43Speaker 1: learning where the machine teaches itself, but we don't really
- 27:46Speaker 1: understand how it's teaching probably the scariest one, right, or
- 27:50Speaker 1: what it's learning, But that's the most prevalent one. That's
- 27:52Speaker 1: what a lot of this is is like these machines.
- 27:54Speaker 1: It's like, here's here's chess, go figure it out and
- 27:59Speaker 1: they go, okay, got it. How did you do that?
- 28:02Speaker 1: Wouldn't you like to know? So that's the scariest presentation
- 28:06Speaker 1: you will see on ai as when someone says, well,
- 28:09Speaker 1: how does all this work? And they go, but we
- 28:12Speaker 1: just know it can beat the human at poker. But
- 28:14Speaker 1: the thing about Deep Stack at the University of Alberta
- 28:17Speaker 1: is that it learned somehow some sort of intuition, because
- 28:22Speaker 1: that's what's required is not just the perfect information where
- 28:26Speaker 1: you have all the information on the board. It's with poker,
- 28:30Speaker 1: you don't know what the other person's cards are and
- 28:32Speaker 1: you don't know if they're lying or bluffing or what
- 28:34Speaker 1: they're doing. Um, so that's an imperfect information game. So
- 28:39Speaker 1: that would require intuition. And apparently not one, but two
- 28:42Speaker 1: different research groups taught AI too into it. Yeah, Carnegie
- 28:47Speaker 1: Mellon came out in uh January of two thousand seventeen
- 28:50Speaker 1: with its Liberatus AI and they said they spent twenty
- 28:54Speaker 1: days playing a hundred and twenty thou hands of Texas
- 28:58Speaker 1: hold them with four professional poker players and one and
- 29:04Speaker 1: smoked him. Basically got up to They weren't playing with
- 29:07Speaker 1: real money obviously, but they they would have been great funded.
- 29:12Speaker 1: Their next project, Liberatis, was up by one point seven million,
- 29:17Speaker 1: and one of the quotes from one of the poker
- 29:19Speaker 1: players that he made two Wired magazine said, I felt
- 29:22Speaker 1: like I was playing against someone who was cheating, like
- 29:24Speaker 1: it could see my cards. I'm not accusing it of cheating,
- 29:27Speaker 1: it was just that good. So that's a really interesting thing. Man,
- 29:32Speaker 1: that they could teach self teach program, or a program
- 29:37Speaker 1: could teach itself intuition. That's creepy. I thought this part
- 29:42Speaker 1: was interesting. The Atari stuff, Um, this gets pretty fun.
- 29:46Speaker 1: Google deep mind. Let it's a i um reek havoc
- 29:52Speaker 1: on Atari forty nine different at twenty games, see they
- 29:56Speaker 1: could figure out how to win, and apparently the most
- 30:00Speaker 1: difficult one was Miss Pacman, which is a tough game.
- 30:04Speaker 1: Still man, Miss pac Man. They nailed it. It's still
- 30:07Speaker 1: one of the great games. But but there um their
- 30:11Speaker 1: game or their Q deep Q network algorithm beat it. Yeah.
- 30:17Speaker 1: I think it got the highest score nine hundred points,
- 30:21Speaker 1: and no human or machine has ever achieved that high
- 30:24Speaker 1: score from what I understand. Amazing and the way this
- 30:26Speaker 1: one does it. The hybrid reward architecture that it uses
- 30:31Speaker 1: is really interesting. It's it says here, it generates a
- 30:34Speaker 1: top agent that's like a senior manager, and then all
- 30:38Speaker 1: these other hundred and fifty individual agents. So it's almost
- 30:41Speaker 1: like they've devised this artificial structural hierarchy of these little
- 30:47Speaker 1: worker agents to go out and collect I guess data
- 30:51Speaker 1: and then move it up the chain to this top agent. Right,
- 30:56Speaker 1: and then this thing says, um, Okay, you know, I
- 31:00Speaker 1: think that you're probably right what these agents are probably doing.
- 31:05Speaker 1: And I don't know this is exactly true, but there's
- 31:08Speaker 1: there are models out there like this where the agent
- 31:11Speaker 1: says this is um, you have a nine chance of
- 31:14Speaker 1: success at getting this pellet um if we take this action.
- 31:19Speaker 1: Somebody else says, you've got a two percent chance of
- 31:21Speaker 1: evading this ghost if we go this way. And then
- 31:24Speaker 1: the the top agent, the senior manager, can put all
- 31:28Speaker 1: this stuff together and say, well, if I listen to
- 31:30Speaker 1: this guy and this guy done, only will I evade
- 31:32Speaker 1: this ghost. I'll go get this pellet um. And it's
- 31:35Speaker 1: based on what what confidence level that the lower agents
- 31:40Speaker 1: have in success in recommending these moves, and then the
- 31:44Speaker 1: top agent ways these things. They should give him a
- 31:47Speaker 1: little a little cap But all this is happening like that,
- 31:51Speaker 1: you know what I'm saying. This isn't like well, hold on,
- 31:53Speaker 1: hold on, everybody, what is Harvey? Harvey? What do you
- 31:55Speaker 1: have to say? Well, let's get some Chinese in here
- 31:58Speaker 1: and and hash it out. And everybody sits there in
- 32:01Speaker 1: order some Chinese food, and then you wait for it
- 32:03Speaker 1: to come and then you pick up the meeting from
- 32:05Speaker 1: that point on. And then finally Harvey gives his idea,
- 32:09Speaker 1: but he forgot what he was talking about, so he
- 32:11Speaker 1: just sits down and eats his agrol. Well here's a
- 32:14Speaker 1: pretty frightening. Uh. Survey. Uh. There was a survey of
- 32:17Speaker 1: more than three fifty AI researchers and they had the
- 32:20Speaker 1: following things to say. And these are the pros that
- 32:23Speaker 1: are doing this for a living. They predicted that within
- 32:26Speaker 1: ten years, ay, I will drive better than we do,
- 32:30Speaker 1: they will be able to write a best selling novel,
- 32:33Speaker 1: A I will generate this, and bye be better at
- 32:37Speaker 1: performing surgery than humans are. You know. So again, one
- 32:42Speaker 1: of the things that about the field of artificial intelligence
- 32:47Speaker 1: a you know a lot about now famous. It is
- 32:50Speaker 1: famous for making huge predictions that did not pan out.
- 32:54Speaker 1: But you've also seen it's it's also famous for beating
- 32:58Speaker 1: predictions that you know been levied against it um. But
- 33:02Speaker 1: there is something in there, Chuck, that stands out to me,
- 33:06Speaker 1: and that's the idea of an AI writing a novel.
- 33:09Speaker 1: Like for a very long time, I thought, well, yeah, okay,
- 33:12Speaker 1: you can teach a robot arm to like put a
- 33:15Speaker 1: car part or something somewhere if you wanted to just
- 33:18Speaker 1: follow these these mechanical things, or it can use in
- 33:21Speaker 1: a wish, or it can use logic and reason. But
- 33:24Speaker 1: to create that's different, right. That was like the new frontier.
- 33:27Speaker 1: It used to be chess and then it used there
- 33:29Speaker 1: was go. The next frontier is creativity, and they're starting
- 33:33Speaker 1: to bang on that door big time. There's a game
- 33:36Speaker 1: designing AI called Angelina out of the University of foul Myth,
- 33:40Speaker 1: which I always want to say foul Mouth, but we'll
- 33:43Speaker 1: just call it Foulmouth like it's supposed to. And Angelina
- 33:46Speaker 1: actually comes up with ideas for new games, not um,
- 33:53Speaker 1: like a different level or something like like you should
- 33:56Speaker 1: put a purple loincloth on that player. You know that'll
- 33:59Speaker 1: look kind of like new games, but whacked out games
- 34:03Speaker 1: that humans would never think of. One example I saw
- 34:06Speaker 1: is in a Dungeon Battle Royal game, a player controls
- 34:10Speaker 1: like ten players at once, and some you have to
- 34:13Speaker 1: sacrifice to be killed to save the others. Like the
- 34:16Speaker 1: stuff that human wouldn't necessarily think of, this AI is
- 34:19Speaker 1: coming up with. Well, I mean, when you think of creatively,
- 34:22Speaker 1: especially something like writing a novel or a film, if
- 34:24Speaker 1: there are only seven stories, I mean, and that sort
- 34:28Speaker 1: of thinking that they're basically every every dramatic story is
- 34:32Speaker 1: a variation of one of seven things. Yeah. So I
- 34:35Speaker 1: mean you can look at like um AI is scary,
- 34:39Speaker 1: and in some ways very much is and can be,
- 34:43Speaker 1: but there's also like definitely a level of excitement of
- 34:46Speaker 1: the whole thing and the idea that there are artificial
- 34:50Speaker 1: minds that are coming online or that have come online now,
- 34:53Speaker 1: that are out there that are they'll they'll just naturally
- 34:56Speaker 1: by definition, see things differently than we do, and the
- 35:00Speaker 1: idea that they can come up with stuff that we've
- 35:02Speaker 1: never even thought of that is just gonna knock our
- 35:03Speaker 1: socks off, hopefully in good ways. Um that's that's a
- 35:07Speaker 1: really cool thing. And so maybe there's just seven as
- 35:11Speaker 1: far as humans know, but there's an unlimited amount if
- 35:14Speaker 1: if you put computer minds to thinking about these kind
- 35:17Speaker 1: of things, that's the premise of it. Right, So the
- 35:19Speaker 1: robot would be like you never thought of boy meets
- 35:22Speaker 1: girl meets well trilo bite. But see even that's a
- 35:28Speaker 1: variation of right, just imagine something that just we've never
- 35:33Speaker 1: even thought. Well, Gina, how they should do this? If
- 35:35Speaker 1: they do do that is uh is not is just
- 35:39Speaker 1: release a book and not tell anyone that was written
- 35:43Speaker 1: by an AI program, because if they do that, then
- 35:46Speaker 1: it's going to be so under scrutiny. They should secretly
- 35:49Speaker 1: release this book and then after it's a New York
- 35:52Speaker 1: Times bestseller, Say, meet the Whopper, the author of this.
- 35:58Speaker 1: You know his interests are rule skating, playing tic tac toe,
- 36:01Speaker 1: and global thermal nuclear war. All right, should we take
- 36:05Speaker 1: a break and get strickling in here. Yeah, we're gonna
- 36:07Speaker 1: end the strickling drought because it is about to reign
- 36:09Speaker 1: strickling in this piece. Gross. Okay, we're back and get this.
- 36:37Speaker 1: The scent of strick has permeated our place, and that's
- 36:41Speaker 1: a beautiful scent. It smells like a soldering gun and
- 36:46Speaker 1: a circuit board. You know, feel the lavender in a
- 36:48Speaker 1: protein bar. That's fair. I'm gonna say, Drac o' noir
- 36:52Speaker 1: that that would have been a lie. Is that how
- 36:54Speaker 1: you said? I always called it Drecar, drac Car. That's
- 36:58Speaker 1: that's fair, d Car. I always pronounced it Benetton colors.
- 37:03Speaker 1: I think that was what I wore. Oh is that
- 37:05Speaker 1: what you wore? Yeah? During my what I call the
- 37:07Speaker 1: Year of Cologne, I had a couple of seven. Uh,
- 37:13Speaker 1: this is scintillating. Why are you? Why am I here?
- 37:17Speaker 1: So we know that you already know because we talked
- 37:20Speaker 1: via email about this, but we'll tell everybody else. We
- 37:23Speaker 1: have brought you in here because you're the master of tech.
- 37:26Speaker 1: And we were talking tech today, which we've talked about
- 37:29Speaker 1: without you before. But frankly, Chuck and I and Jerry
- 37:31Speaker 1: huddled and we said this is not quite as good
- 37:33Speaker 1: without strict so let's try something different. Got you and
- 37:37Speaker 1: and we're talking about games and machine versus man and
- 37:42Speaker 1: that whole whole evolution and how that's gone super crazy
- 37:46Speaker 1: over the last few years. Games without frontiers, Peter Gabriel
- 37:49Speaker 1: would say, war without fear. And we've talked, I mean,
- 37:51Speaker 1: we've talked a lot about the evolution of machine learning
- 37:55Speaker 1: and how now it's starting to take off like a
- 37:57Speaker 1: rocket because they can teach themselves. But one thing we
- 38:00Speaker 1: haven't really talked about are solved games. And we talked
- 38:04Speaker 1: about chess. Yeah, we talked about go right with those
- 38:08Speaker 1: constitutes solved games, not really so so a solved game
- 38:12Speaker 1: is the concept where if you were to assume perfect
- 38:15Speaker 1: play on either sides of the game, you would always
- 38:19Speaker 1: know how it was going to end, which we always
- 38:21Speaker 1: assume perfect play, right, that's kind of work bags stuff
- 38:24Speaker 1: should know motto. So perfect play just means that no
- 38:27Speaker 1: one ever makes a mistake, so very much the way
- 38:29Speaker 1: I do my work right stuff exactly. So, if you
- 38:33Speaker 1: were to take a game like Tic tac toe and
- 38:36Speaker 1: you assume perfect play on both sides, it is always
- 38:38Speaker 1: going to end in a draw, which is what's in
- 38:41Speaker 1: war games. Yes, right, the only way to win is
- 38:43Speaker 1: not to play. Yes, so a game, it's a game
- 38:48Speaker 1: like Connect four, whoever goes first is always going to win,
- 38:52Speaker 1: assuming perfect play sides. Yes, what, I don't think I've
- 38:57Speaker 1: played Connect for it. That's where you dropped for a
- 38:59Speaker 1: long time, when where you drop the little uh tokens
- 39:04Speaker 1: kind of checkers. We did an interstitial playing Connect for Remember,
- 39:07Speaker 1: I was speaking it though, and you had perfect place,
- 39:09Speaker 1: so I knew it was useless. I was gonna say
- 39:11Speaker 1: that I'm so humiliated by all the Connect four games
- 39:14Speaker 1: that I've lost starting even Yeah, but but I mean
- 39:18Speaker 1: perfect play. That's something that that obviously only the the
- 39:22Speaker 1: best players typically achieve with with significantly complex games. Obviously,
- 39:27Speaker 1: the simpler the game, the easier it is to play perfectly.
- 39:31Speaker 1: Right tic tac toe? If you know, once you've mastered
- 39:34Speaker 1: the basics of tic tac toe and the other person has,
- 39:36Speaker 1: you're never really going to win unless someone has just
- 39:39Speaker 1: made a silly mistake because they weren't paying attention like
- 39:43Speaker 1: a star instead of an ex right, which doesn't count
- 39:46Speaker 1: automatically disqualified you. One thing I found this very enjoyable
- 39:50Speaker 1: is playing with little kids who haven't figured out that
- 39:52Speaker 1: tic tac toe is very easy to bring. Yes, smashed
- 39:55Speaker 1: their face on the board, rub it in. Yeah, the
- 39:58Speaker 1: same reason why I like to join in on little
- 40:00Speaker 1: league games, because I can really whale that ball out
- 40:02Speaker 1: of the park. Yeah, it really missed me, feel like
- 40:05Speaker 1: a man. That's the most tech stuffy thing you've ever said.
- 40:07Speaker 1: You really wail that ball out of the park. Well,
- 40:10Speaker 1: to be fair, I did just do a tech stuff
- 40:12Speaker 1: episode about the technology behind baseball bats so fresh. Actually
- 40:17Speaker 1: it's a lot of fun. So there have been a
- 40:19Speaker 1: lot of games that have been solved, but Checkers was
- 40:22Speaker 1: one that was recently solved back in recently by the
- 40:25Speaker 1: early nineties when it was played against a computer called
- 40:29Speaker 1: Chinook and uh h I in O okay, yeah, like
- 40:33Speaker 1: the helicopter or the winds that blow through Alberta exactly.
- 40:37Speaker 1: And so there are certain games that are more easily
- 40:42Speaker 1: solved than others. You do it through an algorithm, but
- 40:45Speaker 1: other games, like chess, are more complicated because you can
- 40:48Speaker 1: in chess you have multiple moves that you can do
- 40:51Speaker 1: where you can you can move a piece back the
- 40:53Speaker 1: way you win, right, it's not you're not committed to
- 40:56Speaker 1: going a specific direction with certain pieces, like with a
- 40:59Speaker 1: night you know you can you could go right back
- 41:01Speaker 1: to where you started on the next move if you
- 41:03Speaker 1: wanted to, and that creates more complexity. So the more
- 41:08Speaker 1: complex the game, the more difficult it is to solve.
- 41:10Speaker 1: And some games are not solvable simply because you'll never
- 41:14Speaker 1: know what the full state of the game is from
- 41:18Speaker 1: any given moment. Did you have a chance to talk
- 41:21Speaker 1: about the difference between perfect knowledge and imperfect knowledge and
- 41:25Speaker 1: a game. Yeah, yeah, we talked about that. Yeah, so
- 41:28Speaker 1: so computers obviously, they do really well if they understand
- 41:33Speaker 1: the exact state of the game all the way through.
- 41:35Speaker 1: If they if they have perfect knowledge, all of the
- 41:37Speaker 1: information is there on the board right and and all
- 41:40Speaker 1: players can see all information at all times. But games
- 41:43Speaker 1: like poker what you guys talked about, obviously you have
- 41:46Speaker 1: imperfect information. You only know part of the state of
- 41:49Speaker 1: the game. That's why those games have been more difficult,
- 41:52Speaker 1: more challenging for computers to get better than humans until
- 41:57Speaker 1: relatively recently. And there've been two major ways of doing that.
- 42:00Speaker 1: You either throw more processing power at it, like you
- 42:03Speaker 1: get a supercomputer, or you create neural networks, artificial neural networks,
- 42:07Speaker 1: and you start teaching computers to quote unquote learn the
- 42:11Speaker 1: white people do. So we talked about that, and one
- 42:15Speaker 1: of the things that we talked about was how there's
- 42:17Speaker 1: this idea that they the programmers, especially, say, the people
- 42:22Speaker 1: who are making programs that are playing poker and are
- 42:24Speaker 1: getting good at poker, aren't exactly sure how the machines
- 42:28Speaker 1: are learning to play poker or what they're learning. They're
- 42:31Speaker 1: just getting better at poker. Do they know how they're
- 42:35Speaker 1: learning poker? They just know that they're learning poker and
- 42:38Speaker 1: that they're good at it. Like, where's the intuition? How
- 42:41Speaker 1: is that being learned? An excellent question. The way it
- 42:44Speaker 1: typically is learned, especially with artificial neural networks, is that
- 42:47Speaker 1: you you set up the computer to play millions of
- 42:52Speaker 1: hands of poker that are are randomly assigned, so it's
- 42:56Speaker 1: it's truly as random as computers can get. That's the
- 42:59Speaker 1: whole philosophical discussion that I don't think we're ready to
- 43:02Speaker 1: go into right now. But you have games come up
- 43:06Speaker 1: where the computer is playing itself millions upon millions of
- 43:10Speaker 1: times and learning every single time how the statistics play out,
- 43:15Speaker 1: how different betting strategies play out. It's it's sort of
- 43:19Speaker 1: partitioning its own mind to play against itself. And through
- 43:23Speaker 1: that process, it's as if you, as a human player,
- 43:27Speaker 1: we're playing thousands of games with your friends and you
- 43:30Speaker 1: start to figure out, oh, when I have these particular
- 43:33Speaker 1: cards and they're in my hand, and let's say we're
- 43:35Speaker 1: playing Texas, hold them and the community cards are are these?
- 43:39Speaker 1: Then I know that generally speaking, maybe three times out
- 43:43Speaker 1: of ten I end up winning, maybe I shouldn't bet.
- 43:45Speaker 1: And well, the computer is doing that, but on a
- 43:47Speaker 1: scale that far dwarfs what any human can do, and
- 43:51Speaker 1: in a in a fraction in the amount of time,
- 43:53Speaker 1: And so it's it's sort of well, it's intuition in
- 43:57Speaker 1: the sense of it's just done it so much, right,
- 44:00Speaker 1: But is that? Does that mean it's completely ignoring um
- 44:05Speaker 1: micro expressions and facial cues, So that didn't even come
- 44:08Speaker 1: into play? Ye, yeah, I was. I was waiting for
- 44:13Speaker 1: you've been doing this. I still nod when I do
- 44:15Speaker 1: a solo show and I do a lot of expressive dance.
- 44:18Speaker 1: What do you think, Jonathan, I don't know, Jonathan. It
- 44:21Speaker 1: gets lonely in here, guys. But yes, what you're saying
- 44:25Speaker 1: all the tells. It tells that you would use as
- 44:28Speaker 1: a human player. The computer does not pick up typically data. Yes, typically,
- 44:33Speaker 1: what it would do is it would study the outcomes
- 44:35Speaker 1: of the games from a purely statistical expressions. Most of
- 44:40Speaker 1: these poker games tend to be computer based poker games.
- 44:43Speaker 1: So it's not that it's playing like it's it's not
- 44:45Speaker 1: like there's a computer that says push ten more chips
- 44:48Speaker 1: into the table. You know, it's right, exactly, a little
- 44:53Speaker 1: it's a little winky face emoticon, like I don't have
- 44:56Speaker 1: good cards. No, it's it's all usually over of like
- 45:00Speaker 1: internet poker, which a lot of the people who play
- 45:03Speaker 1: professional poker cut their teeth on, especially you know in
- 45:06Speaker 1: the more recent generations of professional poker players. Yeah, they
- 45:11Speaker 1: don't know what it's like being a smokey saloon like Moneymaker.
- 45:15Speaker 1: In money Maker rose to the top a few years ago,
- 45:17Speaker 1: more than like a decade ago. Now he had come
- 45:20Speaker 1: from the world of internet poker, and so he was
- 45:23Speaker 1: using those same sort of skills in a real world setting.
- 45:27Speaker 1: But obviously there are subtle things that we humans do
- 45:31Speaker 1: in our expressions that computers do not pick up on,
- 45:33Speaker 1: and in fact that leads us sort of into the
- 45:36Speaker 1: realm of games where computers don't do as well as humans.
- 45:41Speaker 1: Is that list you sent a joke or is it really? No,
- 45:44Speaker 1: that's real. It does seem like it's weird, like one
- 45:46Speaker 1: of the games on there is Pictionary, for example, or tag. Yeah,
- 45:50Speaker 1: but these are some of these are are They sound silly,
- 45:54Speaker 1: But when you start to think about them in terms
- 45:55Speaker 1: of computation and robotics, you start to realize how incredibly
- 45:59Speaker 1: complex it is from a technical perspective, but incredibly easy
- 46:03Speaker 1: it is for your average human being. So with humans
- 46:07Speaker 1: a game of tag, once you know the basics, it's
- 46:10Speaker 1: it's all an instinct. You know what to do. You
- 46:12Speaker 1: run after the person you tried to catch up with
- 46:14Speaker 1: them and tag them. But you also know push him
- 46:16Speaker 1: in the back as hard as you can. Well, if
- 46:19Speaker 1: you're Josh, you push him as hard as you can.
- 46:20Speaker 1: But most of us we tag and we're not trying
- 46:22Speaker 1: to cause harm. Robots, however, robots not so good on
- 46:29Speaker 1: you said, and just say Isaac Asimov Isaac Asimov's rules
- 46:33Speaker 1: of robotics. Aside, robots are not very good at judging
- 46:36Speaker 1: how hard they have to hit something in order to
- 46:39Speaker 1: make contact, right. They're not as good at even your
- 46:43Speaker 1: bipedal robots that walk around like people, even the ones
- 46:46Speaker 1: that can run and do flips and stuff. Have you
- 46:48Speaker 1: seen that one the other day that the footage of
- 46:50Speaker 1: that thing running and jumping, it's really impressive and in
- 46:53Speaker 1: super creepy. Yeah, but even so, that's that's a clip
- 46:58Speaker 1: of the best of If you ever if you ever
- 47:00Speaker 1: see the clips where they show all the times the
- 47:02Speaker 1: robots fallen over, we'll pouring hot coffee in someone's head. Yes,
- 47:07Speaker 1: but they always play those clips shows to Yake, yes
- 47:10Speaker 1: that this this is true. So so, DARPA had its
- 47:13Speaker 1: big robotics challenge a few years ago where they had
- 47:16Speaker 1: bipedal robots tried to go through a scenario that was
- 47:21Speaker 1: simulating the Fukushima nuclear disaster. So the interesting thing was
- 47:26Speaker 1: the robot had to complete a series of tasks that
- 47:29Speaker 1: would have been mundane to humans, things like open up
- 47:32Speaker 1: a door and walk through it, and pick up a
- 47:35Speaker 1: power power tool and use it against a wall. And
- 47:39Speaker 1: you can watch the footage of some of these robots
- 47:42Speaker 1: doing things like being unable to open the door because
- 47:46Speaker 1: they can't tell if they need to pull or push
- 47:49Speaker 1: or they open the door, but then immediately fall over
- 47:51Speaker 1: the threshold of the door. And when you see that,
- 47:54Speaker 1: you realize, as advanced as robotics is, as advanced as
- 47:58Speaker 1: machine learning has become, as incredible as our technology has progressed,
- 48:04Speaker 1: there are still things that are fundamentally simple to your
- 48:07Speaker 1: average humans that are incredibly complicated from a technical standpoint,
- 48:11Speaker 1: Like a six year old can play jinga better than
- 48:13Speaker 1: a robot, right right, right, Okay, But the thing is
- 48:16Speaker 1: we're talking robots here, and is we go more and
- 48:18Speaker 1: more and more online in our world, becomes more and
- 48:21Speaker 1: more like web based rather than reality based. Doesn't the
- 48:27Speaker 1: the fact that a robot can't walk through a door
- 48:29Speaker 1: matter less and less. And the idea that that machines
- 48:34Speaker 1: are learning intellect and the robotivity, you just blew my
- 48:39Speaker 1: mind that that's becoming more and more vital and important
- 48:42Speaker 1: and something we should be paying attention. It absolutely is
- 48:45Speaker 1: something we should pay attention to. I mean, we have
- 48:47Speaker 1: robotic stock traders there trading on thousands of trades per second,
- 48:53Speaker 1: right fast, so fast that we have had stock market
- 48:56Speaker 1: booms and crashes that last less than a second long
- 49:00Speaker 1: due to that. So the robot army that will ultimately
- 49:03Speaker 1: defeat us is not something from the terminator. It's invisible.
- 49:07Speaker 1: It's online, or it will be online. It's it's it's
- 49:10Speaker 1: it's what's determining our retirement, right, yeah, the global economy
- 49:15Speaker 1: or um our municipal waters apply or whatever. Yeah. Now
- 49:19Speaker 1: there's the fascinating thing to me about this is not
- 49:24Speaker 1: just that we're training machine intelligence to learn and to
- 49:28Speaker 1: perform at a level better than humans, but that we're
- 49:31Speaker 1: putting a lot of trust in those devices and things
- 49:36Speaker 1: that have real incredible impact on our lives, the significant
- 49:41Speaker 1: enough impact where if things were to go south, it
- 49:43Speaker 1: would be really bad for us. Uh, and not in
- 49:46Speaker 1: that Terminator respect. Terminator is a terrifying dystopian science fiction story.
- 49:53Speaker 1: But then when you realize what could really happen behind
- 49:56Speaker 1: the scenes, you think the robots don't have to do
- 49:59Speaker 1: any physical harm to us to really mess things up.
- 50:02Speaker 1: So there are certainly some cases for us to be
- 50:06Speaker 1: very vigilant in the way we deploy right from the
- 50:11Speaker 1: outset exactly, and that it depends not necessarily I think.
- 50:17Speaker 1: I think it's I don't think it's too late, but
- 50:21Speaker 1: I think it's getting to that point of no return
- 50:25Speaker 1: very very quickly. December of this year. Yeah, Well, if
- 50:28Speaker 1: you're if you're someone like if you're someone like Elon Musk,
- 50:31Speaker 1: you'd say, if we don't do something now, we're we're
- 50:34Speaker 1: totally going to plummet off the edge of the cliff.
- 50:37Speaker 1: But now is a window that is rapidly closing. Yes, yeah, yeah,
- 50:41Speaker 1: the now is the now is a time where we've
- 50:43Speaker 1: got a deadline. We don't know exactly when that deadline
- 50:47Speaker 1: is going to be up, but we know that it's
- 50:50Speaker 1: not getting further out it. We're just getting closer to
- 50:52Speaker 1: that deadline. So, and a lot of this is is
- 50:56Speaker 1: it covered in deep conversations and the artificial and eligience
- 51:00Speaker 1: and machine learning fields that has been going on for ages,
- 51:04Speaker 1: to the point where you even have bodies like the
- 51:07Speaker 1: European Union that have debated on concepts like granting personhood
- 51:12Speaker 1: to artificial intelligence. So this is a really fascinating and
- 51:17Speaker 1: deep subject that and the games thing is a great
- 51:21Speaker 1: entry point into having that conversation. Uh, you know, I'm
- 51:25Speaker 1: lucky if I can win a game of chess against
- 51:26Speaker 1: another human being. Right, So, I can't even describe chess,
- 51:31Speaker 1: did I did. My big thing is I do that
- 51:33Speaker 1: night thing I called the night shuffle. I just move
- 51:35Speaker 1: them back and forth. I just castle. If I can castle,
- 51:39Speaker 1: then I'm I'm I'm so happy. And that's the third
- 51:43Speaker 1: tech stuffiest thing to come in threes. Well, strict, thank
- 51:46Speaker 1: you for stopping by. Thank you should stick around for
- 51:49Speaker 1: a listener mail. I think you should too, love to
- 51:52Speaker 1: and and throw out any funny comments that you have
- 51:55Speaker 1: I'll throw out comments and then Jerry can decide which
- 51:58Speaker 1: ones are funny. Okay, all right, fair, all right, So
- 52:01Speaker 1: if you want to know more about AI, go listen
- 52:03Speaker 1: to Tech Stuff. Strict does this every week, what days, Monday, Tuesday, Wednesday, Thursday,
- 52:10Speaker 1: and Friday. That's amazing, buddy, and wherever you find your
- 52:14Speaker 1: podcast Okay, and you've been doing it for years, so
- 52:18Speaker 1: if you love this, there's a whole big backlog, nine
- 52:20Speaker 1: plus episodes you're celebrating. You're celebrating your ten year as well,
- 52:24Speaker 1: right yep, by sure, m I'll be uh, we'll be
- 52:26Speaker 1: turning ten and Tech Stuff on June eleven, congratulating. Well,
- 52:31Speaker 1: since I said happy anniversary, it means it's time for
- 52:33Speaker 1: listener mail. Guys. I'm gonna call this, uh Matt graining
- 52:39Speaker 1: and cultural relativism about that. Hey, guys, love your podcast
- 52:44Speaker 1: so much. The massive archive makes for endless learning and entertainment.
- 52:47Speaker 1: My favorite part is you were such rad guys, including Strickland,
- 52:51Speaker 1: and I could totally imagine how did they know? I
- 52:54Speaker 1: can totally imagine myself getting a beer with you two,
- 52:57Speaker 1: But without Strickland, your Simpsons episodes were absolutely perfect. I
- 53:01Speaker 1: used to live in Portland and drove on Flanders and
- 53:03Speaker 1: love Joy Streets a lot. Wait, is this Matt Greening,
- 53:07Speaker 1: Matt Graenning, Drew bart and the sidewalk cement behind Lincoln
- 53:11Speaker 1: High School in downtown Portland's You can google that. I
- 53:14Speaker 1: would like to offer one interesting observation though, I've noticed
- 53:17Speaker 1: that on several episodes, you guys have said that you
- 53:19Speaker 1: are cultural relativists. Is that pronounced right? Yeah? But then
- 53:23Speaker 1: in nearly every episode I hear you pass moral judgments
- 53:27Speaker 1: on all the messed up stuff that people do, whether
- 53:29Speaker 1: it's racism, freak shows, or crematori ums bearing bodies on
- 53:33Speaker 1: the sly you guys are never shy to condemn something
- 53:36Speaker 1: that deserves to be condemned. Reminds me of something I
- 53:38Speaker 1: read from Yale sociologists who Loop Gorsky, who points out
- 53:43Speaker 1: that our own relativism is rarely as radical as our
- 53:47Speaker 1: theory requires. We can't be complete relativists in our daily lives.
- 53:52Speaker 1: He then gives the example of how academic social scientists,
- 53:55Speaker 1: where die hard relativists, get furious at uh and moralistic
- 53:59Speaker 1: at the data fudging of other researchers. Anyway, love the show, guys,
- 54:04Speaker 1: love tech stuff especially, and will forever be indebted to
- 54:07Speaker 1: you for your hilarity and knowledgeability. Cheers Jesse Lusco ps
- 54:13Speaker 1: go tech stuff. That's that's sweet. So yeah, thanks a lot, Jesse. Um.
- 54:18Speaker 1: There was an actual episode, and I don't remember which
- 54:20Speaker 1: one it was, where we abandon our cultural relativism, do
- 54:23Speaker 1: you remember, Because we used to just be like, no judgment,
- 54:26Speaker 1: no judgment, we just can't judge, you know, and then
- 54:29Speaker 1: finally we're like, you know what, No, that's not true.
- 54:32Speaker 1: We changed our the our philosophy to include the idea
- 54:35Speaker 1: that there are moral absolutes that are universal, although sometimes
- 54:40Speaker 1: we are just judging even beyond that. Look at us. Yeah, well,
- 54:44Speaker 1: if you want to get in touch with us, you
- 54:46Speaker 1: can tweet to us. I'm at josh um Clark and uh,
- 54:50Speaker 1: John Strickland's at John Strickland. That's correct. On Twitter, Chuck's
- 54:54Speaker 1: a movie crush and uh, you have a tech stuff
- 54:57Speaker 1: hsw Twitter, right, that's right. And then we also have
- 54:59Speaker 1: s y sk podcast. We're on Facebook dot com slash
- 55:02Speaker 1: stuff you should know, slash tech stuff and slash movie Crush.
- 55:07Speaker 1: Do you have a movie crush page for Facebook? Yeah? Yeah,
- 55:10Speaker 1: that's actually where I spend most of my time. Oh,
- 55:12Speaker 1: I didn't know that, said it's time. And then there's
- 55:15Speaker 1: also a slash stuff you Should Know Facebook page. You
- 55:17Speaker 1: guys have a lot of Facebook and to do it
- 55:19Speaker 1: so many social medias flying around. You can send us
- 55:22Speaker 1: an email to stuff podcast at how stuff Works dot com.
- 55:25Speaker 1: You can send John an email to tex stuff at
- 55:28Speaker 1: how stuff Works dot com. Nice, and then hang out
- 55:30Speaker 1: with us at our home on the web Stuff you
- 55:32Speaker 1: Should Know dot com and just go to tech stuff.
- 55:36Speaker 1: Just search it in Google. I come up all the time.
- 55:38Speaker 1: Fair enough for more on this and thousands of other topics,
- 55:46Speaker 1: is it how stuff Works dot com
