  • (leaves rustling)

  • As fall breaks out in Canada,

  • I'm reminded of all the beauty, innocence and gun-free fun

  • available from our neighbors to the North.

  • (majestic music)

  • There's the majesty of Toronto,

  • vast hockey rinks,

  • spectacular batches of poutine,

  • and gallons of maple syrup that you can chug openly

  • and guilt-free for this maple syrup is pure and nourishing.

  • The changing of the seasons also happens to be

  • the perfect time to encounter one of Canada's

  • most prized creatures,

  • the artificial intelligence nerd.

  • (resolute music)

  • Not too long ago, these beings were rare

  • and hidden away in university dungeons.

  • But today they flourish.

  • They primp with instinctual grace.

  • They wave their hands impressively

  • to assert their intellectual dominance.

  • They carb-load like overpaid professional athletes.

  • And this makes some sense because they're among

  • the best paid professionals in the world.

  • Together these creatures did something truly remarkable.

  • Without anyone paying much notice,

  • they gave birth to an AI revolution.

  • They turned Canada, yes, Canada,

  • into one of the great AI superpowers.

  • This is the story of how all this came to be.

  • It's the story of one nation's quest

  • to teach computers to think like humans.

  • It's the story of what this science experiment will mean

  • for all our lives and for the future of the human species.

  • So if you're a human, or something trying to imitate one,

  • you'll wanna pay attention.

  • Ever since people first came up with the idea of computers,

  • they've dreamed of imbuing them

  • with artificial intelligence.

  • I am a smart fellow

  • as I have a very fine brain.

  • That's the most remarkable thing I've ever seen.

  • AI is just a computer that is able to mimic

  • or simulate human thought or human behavior.

  • Within that there's a subset called machine learning

  • that it's now the underpinning

  • of what is most exciting about AI.

  • By allowing computers to learn

  • how to solve problems on their own,

  • machine learning has made a series of breakthroughs

  • that once seemed nearly impossible.

  • It's the reason computers can understand your voice,

  • spot a friend's face in a photo, and steer a car.

  • And it's the reason people are actively talking

  • about the arrival of human-like AI.

  • And whether that would be a good thing

  • or a horrific end of days thing.

  • Many people made this moment possible,

  • but one figure towers above the rest.

  • I've come to the University of Toronto

  • to see the man they call the godfather

  • of Modern Artificial Intelligence.

  • Geoff Hinton.

  • (calm music)

  • Because of a back condition, Geoff Hinton hasn't been able

  • to sit down for more than 12 years.

  • I hate standing.

  • I much rather sit down, but if I sit down

  • I have a disc that comes out.

  • Well at least now standing desks are fashionable.

  • Yeah, but I was ahead.

  • (laughter)

  • I was standing when they weren't fashionable.

  • Since he can't sit in a car or on a bus,

  • Hinton walks everywhere.

  • The walk says a lot about Hinton and his resolve.

  • For nearly 40 years, Hinton has been trying to get computers

  • to learn like people do, a quest almost everyone

  • thought was crazy or at least hopeless,

  • right up until the moment it revolutionized the field.

  • Google thinks this is the future of the company,

  • Amazon thinks this is the future of the company,

  • Apple thinks this is the future of the company,

  • my own department thinks it's just probably nonsense

  • and we shouldn't be doing any more of it.

  • (laughter)

  • So I talked everybody into it except my own department.

  • You obviously grew up in the UK

  • and you had this very prestigious family

  • full of famous mathematicians and economist,

  • and I was curious what it was like for you.

  • Yeah, there was a lot of pressure.

  • I think by the time I was about seven

  • I realized I was gonna have to get a PhD.

  • Did you rebel against that or you--

  • I dropped out every so often.

  • I became a carpenter for a while.

  • Geoff Hinton, pretty early on, became obsessed

  • with this idea of figuring out how the mind works.

  • He started off getting into physiology,

  • the anatomy of how the brain works,

  • then he got into psychology, and then finally he settled

  • on more of a computer science approach

  • to modeling the brain and got in to artificial intelligence.

  • My feeling is if you wanna understand

  • a really complicated device, like a brain,

  • you should build one.

  • I mean you could look at cars and you could think

  • you could understand cars.

  • When you try and build a car you suddenly discover

  • this is stuff that has to go under the hood,

  • otherwise it doesn't work. Yeah.

  • As Geoff was starting to think about these ideas,

  • he got inspired by some AI researchers across the pond.

  • Specifically this guy, Frank Rosenblatt.

  • Rosenblatt, in the late 1950s,

  • developed what he called a Perceptron,

  • and it was a neural network, a computing system

  • that would mimic the brain.

  • The basic idea is a collection of small units

  • called neurons, these are little computing units

  • but they're actually modeled on the way

  • that the human brain does its computation.

  • They take incoming data like we do from our senses

  • and they actually learn so the neural net can learn

  • to make decisions over time.

  • Rosenblatt's hope was that you could feed a neural network

  • a bunch of data like pictures of men and women

  • and it would eventually learn how to tell them apart,

  • just like humans do.

  • There was just one problem.

  • It didn't work very well.

  • Rosenblatt, his neural network

  • was a single layer of neurons

  • and it was limiting what it could do, extremely limited.

  • And a colleague of his wrote a book in the late '60s

  • that show these limitations.

  • And it kinda put the whole area of research

  • into a deep freeze for a good 10 years.

  • No one wanted to work in this area.

  • They were sure it would never work.

  • Well, almost no one.

  • It was just obvious to me that it was the right way to go.

  • The brain's a big neural network

  • and so it has to be that stuff like this can work

  • 'cause it works in our brains.

  • There's just never any doubt about that.

  • What do you think it was inside of you

  • that kept you wanting to pursue this

  • when everyone else was giving up,

  • just that you thought it was the right direction to go?

  • I know that everyone else was wrong.

  • Okay.

  • Hinton decides he's got an idea

  • of how these neural nets might work,

  • and he's gonna pursue it no matter what.

  • For a little while, he's bouncing around

  • research institutions in the US.

  • He kinda gets fed up that most of them are funded

  • by the defense departments and he starts looking

  • for somewhere else he can go.

  • I didn't wanna take defense department money.

  • I sort of didn't like the idea

  • that this stuff was gonna be used

  • for purposes that I didn't think were good.

  • He suddenly hears that Canada might be interested

  • in funding artificial intelligence.

  • And that was very attractive,

  • that I could go off to this civilized town

  • and just get on with it.

  • So I came to the University of Toronto.

  • And then in the mid '80s, we discovered

  • I had to make more complicated neural nets

  • so they could solve those problems

  • that the simple ones couldn't solve.

  • He and his collaborators developed

  • a multi-layered neural network, a deep neural network.

  • And this started to work in a lot of ways.

  • Using a neural network, a guy named Dean Pomerleau

  • built a self-driving car in the late '80s,

  • and it drove on public roads.

  • Yann LeCun, in the '90s, built a system

  • that could recognize handwritten digits

  • and this ended up being used commercially.

  • But again they hit a ceiling.

  • They didn't work quite well enough

  • because we didn't have enough data,

  • we didn't have enough compute power.

  • And people in AI, in computer science,

  • decided neural networks was wishful thinking basically.

  • So it was a big disappointment.

  • Through the '90s into the 2000s,

  • Geoff was one of only a handful of people on the planet

  • who are still pursuing this technology.

  • He would show up at academic conferences

  • and being banished to the back rooms.

  • He was treated as really like a pariah.

  • Was there like a time when you thought,

  • this just wasn't gonna work? No.

  • And you did have some self-doubt?

  • I mean there were many times when I thought,

  • I'm not gonna make this work.

  • But Geoff was consumed by this and couldn't stop.

  • He just kept pursuing the idea that computers could learn.

  • Until about 2006, when the world catches up

  • to Hinton's ideas.

  • Computers were now a lot faster.

  • And now it's behaving like I thought

  • it would behave in the mid '80s.

  • It's solving everything.

  • The arrival of superfast chips

  • and the massive amounts of data produced on the internet

  • gave Hinton's algorithms a magical boost.

  • Suddenly computers could identify what was in an image,

  • then they could recognize speech

  • and translate from one language to another.

  • By 2012, words like neural nets and machine learning

  • were popping up on the front page of The New York Times.

  • You have to go all these years

  • and then all of a sudden, in the span of a few months,

  • it just takes off and it finally feel like, aha,

  • the world has finally come to my vision.

  • It's sort of a relief that people

  • finally came to their senses.

  • (laughter)

  • Next up, we have Professor Geoffrey Hinton

  • of the University of Toronto.

  • (applause)

  • Thank you.

  • (calm music)

  • For Hinton, this is obviously a really redemptive moment.

  • Now he's basically a technology celebrity.

  • And for Canada, it's the country's moment as well.

  • They have more AI researchers

  • than just about any other place on the planet

  • and the quest now is to see what these guys can do,

  • starting companies and pushing the technology forward.

  • I'm gonna set out on a journey across Canada

  • to see the best in Canadian AI technology

  • and to get a feel for how far the technology has come

  • and how far it still has to go.

  • Here is a city that gets right at the central tension

  • of modern life and the unfolding AI revolution.

  • (church bell ringing)

  • It's Montreal, a place filled with beauty

  • and old world charms that ask you to move

  • slowly through its streets and to chill for a while,

  • reflect, and think deep thoughts.

  • (calm music)

  • At the same time, it's one of the world's

  • top AI research centers.

  • Students flock here from all over the globe

  • to get deep with machine learning

  • and to take Geoff Hinton's ideas and figure out

  • how to turn them into products we all use.

  • To see just how successful they've been,

  • look no further than your pocket.

  • All this stuff started out as hardcore computer science,

  • but over the last five years AI has invaded

  • our everyday lives.

  • Your smartphone is packed full of AI-powered apps

  • including something like Google Translate

  • that lets you point your phone at a magazine

  • that's written in French and read it as if you're a local.

  • Engineers have been trying to get computers

  • to translate text like this for decades,

  • but it was Geoff's neural nets

  • that finally made it possible.

  • Thanks, Geoff.

  • And it's not just your smartphone,

  • neural networks are heading for the open road.

  • Off we go.

  • Meet my friend Stephane, the head

  • of Montreal's Tesla Fan Club.

  • I'm driving a Tesla for a little bit

  • more than four years and a half.

  • So do you have people asking you for rides all the time?

  • Yes, all the time.

  • Maybe that's because of his

  • fancy pants autopilot,

  • Tesla's semi-autonomous driving system

  • that kicks in when road conditions are right.

  • So that's it, autopilot's on.

  • Yes, and it's driving by itself.

  • So we need to pay attention

  • but we don't have to drive.

  • That's crazy.

  • (laughter)

  • Self-driving cars are packed full of camera,

  • sensors and radar.

  • When teamed with computer vision neural nets,

  • it's this technology that lets the cars

  • build a picture of the world.

  • The technology has a long way to go,

  • but this Tesla can monitor all the cars around it,

  • switch lanes and park all by itself.

  • Thanks, Geoff.

  • So you're living in the future.

  • Yeah.

  • You know, when you try it once

  • it's very difficult to do without it

  • because I just can be relaxed and we can drive like this.

  • Oops.

  • There's a stop sign.

  • That's why we still need to pay attention.

  • (laughter)

  • Back on the sidewalk, I tap those neural nets again.

  • This time in the form of speech recognition.

  • Find me some poutine, eh.

  • I found a few places within 8.4 kilometers.

  • Speech recognition used to suck,

  • but now it's pretty darn good.

  • Why?

  • A neural net of course.

  • Thanks, Geoff.

  • The Google brain sent me here.

  • For an artery hardening affair with poutine.

  • Once a simple Quebec dish of cheese curds,

  • French fries and gravy, it's been disrupted.

  • The dandan, pepperoni, bacon and onions.

  • Here we go.

  • It's gooey, glorious and blessedly algorithm-free.

  • Well now the humans are toast

  • when they could make stuff like this.

  • (calm music)

  • A big part of Hinton's legacy lies beyond

  • these examples of AI in the world.

  • He's also inspired a legion of disciples

  • spreading the good word of neural nets.

  • Yoshua Bengio is a professor at the University of Montreal,

  • he's one of the researchers who gloomed on to Hinton's ideas

  • when it seemed to make little sense to do so.

  • Over the years, he's formed a mind meld with Hinton,

  • and together they've come up with many of the key concepts

  • behind modern AI.

  • You guys worked on this stuff through the '80s,

  • the '90s, to 2000s and then it just seemed like

  • this totally went from computer science and research

  • to we see it everywhere in our lives.

  • Are even you surprised what's happened

  • in the last five years that it really is

  • like sitting on all our phones and--

  • The rate at which the progress and the industrial products

  • have been coming up is totally something we didn't expect.

  • Even now it's hard to predict,

  • where are we going, is it gonna slow down,

  • or are we gonna continue with this exponential increase.

  • It's thanks to Yoshua that Montreal is full

  • of top notch AI graduate talent.

  • This in turn has brought tech giants

  • like Google and Facebook to town,

  • along with their ample checkbooks.

  • To me, it seems like if you're good at AI

  • you can make $200,000, $300,000 a year.

  • It is crazy to see how much these guys get paid now.

  • A million dollars is something quite common as a salary.

  • Have you ever had a country offer you

  • an incredible money to come set up a lab there?

  • Not a country but, yeah, companies, yeah.

  • But Yoshua has rejected the lucrative offers

  • of big neural net.

  • He remains committed to the ivory towers of academia,

  • which is a better fit for his philosophical approach to AI.

  • You've got guys like Elon Musk and Stephen Hawking

  • that sometimes paint this technology

  • in a very, very dark light that it could run amok

  • and start doing things on its own.

  • What do you feel when you hear people say things like that?

  • I'm not concerned about technology running amok.

  • The Terminator scenario I think is not very credible.

  • And I also believe that if we're able to build machines

  • that are as smart as us, they're also smart enough

  • to understand our values and to understand our moral system

  • and so act in a way that's good for us.

  • Now I think there are real concerns

  • which is essentially misuse of AI

  • to influence people's minds.

  • It's already happening with political advertising.

  • Yeah, we've already seen like the stuff from Facebook.

  • So I think we should be careful about this.

  • And try to regulate the use of AI

  • in places where it's morally wrong or ethically wrong,

  • I think we just, we should just ban it and make it illegal.

  • It's comforting that Yoshua has these concerns.

  • But hop down the road from the university,

  • in reality, or what's left of it, becomes messier.

  • This tiny room is the home to a startup called Lyrebird.

  • It was founded by Yoshua's former students

  • and has built an app that can clone your voice.

  • We were speaking about this new algorithm

  • to copy voices.

  • This is huge.

  • It can make or say anything, really anything.

  • One of its founders is this guy,

  • Mexican expat Jose.

  • He taught me the art of the clone.

  • So you'll need to record yourself

  • for a few minutes of audio.

  • Thousands of letters danced across

  • the amateur author screen.

  • When you start to eat like this, something is the matter.

  • You guys better quit politics and take in washing.

  • I don't know where that one came from (laughs).

  • Okay, so create my digital voice now.

  • Creating your digital voice.

  • Takes at least one minute.

  • One minute, my God.

  • Yeah, so before to create some artificial voice of someone

  • you would need to record yourself for at least eight hours.

  • Test your voice.

  • All right, so now I get to type something.

  • Yeah, so the moment of the truth.

  • Okay.

  • Once Lyrebird's AI has worked its magic,

  • after I'm done typing.

  • Better spell that out.

  • Any words I put into the app can be played back

  • in my digital voice.

  • And here's the crazy thing.

  • Even words I never actually said in the first place.

  • Artificial intelligence technology

  • seems to be advancing very quickly.

  • Should we be afraid?

  • I mean I can definitely hear my voice in there.

  • That's really interesting.

  • I just picked those words at random

  • and I definitely did not say some of them

  • and it's like flawless and being able to sort of pick

  • from just about any word and manufacture it.

  • Hello, world.

  • This is the best show I have ever seen.

  • This technology seems sweet,

  • but lends itself to all manner of trickery.

  • I've popped back to my hotel to test out

  • the Lyrebird technology a little bit.

  • And you could see some really obvious ways

  • that this could be abused.

  • This is fake Donald Trump talking.

  • The United States is considering,

  • in addition to other options,

  • stopping all trade with any country

  • doing business with North Korea.

  • And then you could picture somebody taking over your voice

  • and creating some mayhem in your personal life.

  • Now to really put my computer voice to the test,

  • I'm going to call my dear, sweet mother

  • and see if she recognizes me.

  • (phone ringing)

  • Hey, mom. Hi.

  • What are you guys up to today?

  • I'm just finishing up work and waiting

  • for the boys to get home.

  • Okay.

  • I think I'm coming down with a virus.

  • (laughter)

  • I was messing around with you.

  • You were talking to the computer.

  • (laughs) Is that scary or good?

  • I don't know.

  • (laughter)

  • Is it?

  • (calm music)

  • After realizing that anyone with the time

  • and inclination could mess with my life,

  • there was only one thing left to do.

  • I joined Jose and a few other Lyrebirds

  • to chat more about the evils of AI

  • while dulling my fear with booze.

  • Obviously some people are freaked out by this technology

  • because we're already like blurring the line

  • about truth and reality.

  • Of course there is some risk in people

  • using this kind of technology for bad applications.

  • Unfortunately, technologies it's not possible to stop it.

  • So the ethical path that we have decided

  • is to show these to people, to make them know

  • that this kind of technology is available

  • and to make them more cautious from this kind of subject.

  • We really believe that right now

  • that the technology is not perfect

  • is the right time to let people kind of play with it,

  • get used to it slowly.

  • So you guys think that the idea is just sort of new

  • and that's why it scares people,

  • but if you get used to it it's just,

  • that's just the way it is.

  • We want our technology to be used for positive things.

  • It's not something that we should be really afraid of,

  • it's something that we should be careful about

  • but I feel enthusiastic about.

  • (calm music)

  • It's nice to be enthusiastic.

  • It's also nice to meditate on the consequences

  • of your inventions, instead of turning our souls

  • over to chance and blind luck.

  • But it is kinda cool to be a cynical bastard

  • in my new artisanal computer voice.

  • Welcome Russian friends to our huge,

  • wonderful and very pure elections.

  • The real artificial intelligence weirdos

  • in Canada live here in Edmonton.

  • This is a large but very, very cold

  • and very, very flat city.

  • It is more or less in the middle of nowhere.

  • It's the kind of place that has a giant butter vault

  • to help people survive the lean winter months.

  • Canadians like to put the best possible spin

  • on how these conditions bring out

  • interesting traits in people.

  • Ask anyone.

  • Like this guy from the Edmonton Tourist Center.

  • Well Edmonton's one of those cities

  • that isn't automatically listed in the top cities in Canada

  • in terms of size or scale or notice even.

  • But it's always had a really neat quality to it

  • of that Western independent spirit

  • that you see very much in Alberta in general,

  • combined with a conscience and thoughtfulness.

  • Over at the University of Alberta,

  • some of the most far out AI research in world

  • is taking place.

  • The man I'm here to see is the university's very own

  • AI godfather, Rich Sutton.

  • Rich is considered one of the great

  • revolutionary thinkers in AI.

  • You are not Canadian.

  • I am Canadian.

  • You are (laughs), but not by birth.

  • No, I was born in the US.

  • But now I'm just Canadian.

  • Okay.

  • And what brought you to Canada?

  • The politics.

  • I wanted to get away from difficult times

  • in the United States.

  • United States was invading other countries in 2003

  • when I came here and I didn't care for all that.

  • Sutton entered the field of AI in the mid '80s.

  • And like Geoff Hinton and Yoshua Bengio,

  • he was a big believer in neural networks.

  • But Sutton has a different idea

  • about how to further the technology.

  • Unlike Hinton's method of feeding neural networks

  • reams and reams of data and telling them what to do.

  • Sutton wants them to learn more naturally from experience,

  • an approach called reinforcement learning.

  • Reinforcement learning, it's like what animals do

  • and what people do, try several things,

  • the things that work best you keep doing those

  • and things that don't work out so well you stop doing them.

  • And how do you teach a computer that idea?

  • The computer has to have a sense

  • of what's good and what's bad.

  • And so you give a special signal called a reward.

  • If the reward is high that means it's good,

  • if the reward is low that means it's bad.

  • To see reinforcement learning in action,

  • I found Marlos] an industrious young Brazilian

  • whose created an AI to play his video games for him.

  • His algorithm plays the game thousands of times

  • and gradually learns from experience how to do better.

  • So the goal of this game is that you are this yellow block

  • and what you have to do is that you have to get

  • as many potions as you can while avoiding harpies.

  • And this is like the AI going at this for the first time.

  • It's the AI running for the first time.

  • So it just bumps into things.

  • If it gets points it's happy, if it dies it's unhappy.

  • Yes.

  • And the AI starts to figure out that maybe what I wanna do

  • is to collect the potions and avoid the harpies.

  • And now we can look at AI that has ran for 5,000 games.

  • Okay.

  • And this is what it looks like.

  • You can tell that it's smarter

  • about its strategy. Yes.

  • And then what happens if you run it 500,000 times?

  • Oh, we got you this superhuman performance level.

  • Though notching a high score

  • is the noblest of pursuits,

  • reinforcement learning has turned out to have

  • all kinds of other applications.

  • It's behind the algorithm that recommends movies

  • and TV shows on Netflix and Amazon.

  • It beat the world champion Go player,

  • a feat previously thought impossible for a computer.

  • Soon, it could read your brain waves

  • and determine whether you have a mental disorder.

  • But for Sutton, all that is just the beginning.

  • We are trying to make real intelligence.

  • We're trying to recreate human intelligence.

  • Humans are our examples.

  • He sees reinforcement learning as the path

  • to what futurists call the singularity.

  • The moment when our AI creations light up

  • and surge past human level intelligence.

  • Do you have dates for the singularity or?

  • It's a quite broad probability distribution

  • and the median is at 2040.

  • So that means equal chance being before or after 2040.

  • The rationale goes like this.

  • By 2030, we'll have the hardware.

  • So give guys like me another 10 years to figure out

  • the algorithms,

  • the software to go with the hardware to do it

  • and it's gonna be exciting where we're going.

  • If 2040 seems like a long time

  • to wait to meet a smart robot, do not fret.

  • Over in the experimental wing of the university,

  • there are coeds hard at work learning the line

  • between humans and machines.

  • Are you human?

  • Of course not,

  • but that shouldn't keep us from chatting.

  • Case in point, homegrown Edmontonian genius,

  • Kory Mathewson.

  • Tell me about this guy a little bit or--

  • Yeah, sure.

  • Sure.

  • So this is Blueberry.

  • On Blueberry, I've deployed the Improv System

  • so there's an artificial Improv System

  • running on Blueberry right now.

  • Yes, that's right, Kory does Improv comedy with a robot.

  • I've been doing Improv longer

  • than I've been doing computing science.

  • I've been doing it for 12 years and I thought

  • there's no more natural convergence

  • than taking some of these state-of-the-art systems

  • and putting them up on stage.

  • One day, we'll take it to the moon if this planet

  • is not to be our last.

  • (laughter)

  • The sky, the moon, and the universe.

  • The sun, the sun.

  • The sky, the moon, and the universe.

  • I keep thinking it's like ventriloquist

  • or it is like a new edge.

  • That's really good way to put it, yeah.

  • Strange too as I thought it.

  • The piece that's different is that

  • I don't know what it will say.

  • Anything that comes from the system,

  • it's generating live in the moment.

  • Blueberry, I created you.

  • I downloaded a voice into your brain

  • so that you could perform in front of these people.

  • But I do not know what I'm going to say.

  • I don't know what you're gonna say either.

  • To give Blueberry the power of surreal

  • Canadian Improv, Kory made use of some tech

  • that should be familiar by now, a neural network.

  • Step one, he feeds the network the dialogue

  • from a bunch of movies.

  • 102,000 movies to be exact.

  • All the movies.

  • Every movie for 100 years.

  • And that's just so it can learn language

  • to see how somebody responds to somebody else.

  • That's exactly right.

  • Yeah, it builds kind of language model.

  • Step two, he uses reinforcement learning

  • to train the network.

  • Rewarding it when it makes sense

  • and the punishing it when it spits out gibberish.

  • Time to put this wannabe kid in the hall to the test.

  • There we go.

  • Start improvising.

  • Okay, campers, we're gonna get ready

  • for a real baseball game.

  • Grab your gloves and grab your baseball bats,

  • let's get out there, especially you, Franklin.

  • Okay, okay.

  • Well, why aren't you ready for the match?

  • Okay.

  • Come on, Franklin, you know how I feel about you,

  • but you gotta keep your head in the game right now.

  • It's threatening you?

  • I know.

  • Oh, Jesus, put down the bat, Franklin.

  • What are you doing?

  • I've got nothing to hide.

  • Look, this is all I am.

  • Okay, I'll end it there.

  • That's what how it work. That's great.

  • Obviously, some of the responses are a little bit weird,

  • but that it's really funny 'cause then as you go along,

  • it did hid a couple of things perfectly

  • and then it's like, I mean, it's extra hilarious

  • because, yeah, that's going.

  • Blueberry may not be ready

  • for its second city audition just yet,

  • but Kory has a higher purpose: making AI relatable.

  • Oh, it's gonna move.

  • It's gonna move.

  • It's gonna move.

  • Holy crap.

  • (laughter)

  • There is fear in society of AI.

  • So we are kind of humanizing this AI

  • where we're taking it down a peg.

  • We're saying don't be afraid of this tech.

  • Look at how cute it is.

  • Look at how kind of naive it is.

  • Yeah, yeah, yeah that sounds cool.

  • You've done it again, Blueberry.

  • Isn't there a flip side to that though

  • that you make it cute and then people start to accept it

  • then we wake up?

  • I mean, I don't think that will happen in my time.

  • The singularity may be near or maybe not so near.

  • But if the inhabitants of this oddly beautiful place

  • keep pushing the technology, they just might create

  • something alarmingly human-like one day.

  • For Rich Sutton,

  • it's not a question of whether we'll get there,

  • but whether we'll be able to accept our mechanized brethren.

  • Our society will be challenged.

  • It's just like every time are lack people people,

  • are women people,

  • we will do the same thing with robots eventually.

  • Are they allowed to own property?

  • Are they allowed to earn an income

  • or do they have to be owned by somebody?

  • But a robot is obviously not a person.

  • Right?

  • No.

  • (calm music)

  • (upbeat music)

  • For my last stop, I returned to Toronto.

  • Home to 2.8 million people, one very tall tower,

  • and of course, the godfather himself.

  • Inside the system, there's also little processes

  • which are a little bit like brain cells.

  • He may be an import,

  • but Geoff Hinton has done something

  • truly exceptional for Toronto.

  • He's turned this city into an AI Mecca

  • where AI conferences like this one seem to take place daily

  • (applauding)

  • and where young minds come to show off their ideas.

  • Canada, if we're being honest,

  • doesn't usually seem that intimidating,

  • but thanks to Geoff, it's got nothing

  • less than world domination in mind.

  • We are enormously thankful to Canadians

  • for inventing all these stuff 'cause we now use it

  • throughout our entire business--

  • And we have it on record that he owns

  • that Google owns Canada.

  • We absolutely own Canada, so that was a mistake.

  • The tech industry is full of people who adore AI.

  • And then also some famous types like Elon Musk

  • and Stephen Hawking who said,

  • well, that AI might be the end of us.

  • To consider such dystopia in the proper light,

  • I've come to Toronto's geekiest bar

  • to encase myself in this steel container

  • with George Dvorsky.

  • He's a writer for Gizmodo and an AI philosopher.

  • Since we're in a Apocalyptic bar,

  • what is the con case around AI?

  • What's the nastiest scenario

  • that everybody is worried about?

  • Unfortunately, there is no shortage of nasty scenarios

  • and I think this is what makes artificial intelligence

  • such a scary thing is all the different ways

  • that it can go wrong.

  • It can be everything from an accident

  • where we just didn't think it through.

  • We gave a very powerful computer instructions

  • to do something.

  • We thought we explained it articulately,

  • we thought we gave it a concrete goal

  • and it completely took a different path

  • than we thought it would in such a way

  • that it actually caused some great damage.

  • And I'm sure you've heard the old paper clip example

  • where you're a paper clip manufacturer and you say, hey,

  • we need lots of paper clips,

  • and because the artificial intelligence

  • has so much reach and so much power,

  • it actually starts to go about converting all the matter

  • and all the molecules on the planet into paper clips.

  • Before you know it, we've now converted the entire cosmos

  • into paper clips.

  • It's a crazy scenario, but it's an illustrative scenario.

  • We can't be dismissive of the perils.

  • I think that's exceptionally dangerous

  • and I don't think it's too early

  • to start raising alarm bells about it.

  • Being turned into clippie sounds awful.

  • But fear not, we'll have years

  • to ease into that sort of suffering

  • as AI steadily plucks off one job after another.

  • The first to go, of course, will likely be

  • the always screwed factory workers

  • which brings us to Suzanne Gilbert,

  • a budding AI overlord

  • and founder of robotic startup, Kindred AI.

  • (calm music)

  • Tell me about these guys.

  • So these are research prototypes.

  • So they're some of the first robots we've built at Kindred.

  • We tend to work with small robots.

  • It's a bit like if you imagine a child growing up

  • and it breaks a lot of things.

  • Now, imagine if the child was six feet tall

  • when it have the brain of a six-month-old,

  • it would be terribly dangerous.

  • How many of these robots have ever slapped you?

  • I have been hit in the face by robots a couple of times.

  • Suzanne seems nice enough.

  • She makes exotic digital art.

  • And she loves cats to the point where she has built

  • a robotic fleet of them for the office.

  • This one, I usually call pink foot.

  • It's a quadruped robot loosely based on cat anatomy,

  • although it's not a very highly faithful representation yet.

  • And then when you were growing up,

  • you would build things as well?

  • Yeah, that's correct, yeah.

  • So I was really enthralled by electronics at an early age.

  • I guess most little girls will be looking at

  • trays of beads and things and I was looking at trays

  • of like resistors and capacitors and little components,

  • but having the same kind of reaction to them.

  • But don't be fooled by the hobby electronics

  • and the cute cat bots.

  • Suzanne is a keen business woman.

  • And Kindred has recently embarked

  • on its first commercial venture.

  • What's going on here is that we have a bank of robots

  • that are learning,

  • so they are continuously running picking up objects.

  • These would run all day?

  • All day, all night.

  • Powered by a neural network,

  • these arms can do something that's very easy for a human,

  • but very hard for a bot.

  • Pick up objects of different shapes and put them down.

  • Most factories still use people to do that sort of thing,

  • lots and lots of people.

  • Today, everyone's shopping on ecommerce.

  • Thousands and thousands of different types of objects,

  • shapes, textures, weights, how do you pick that up?

  • Right now as humans, we have millions of humans

  • in warehouses just like picking up things

  • and putting it into another location,

  • so we're teaching our robots how to do that.

  • What's the hard part is figuring out

  • what's a belt, what's a shirt or it's just how to grasp it.

  • Yeah, exactly.

  • It's very hard to pick it up, right?

  • So things will show up in any shape

  • and you gotta figure out how to pick up without dropping it,

  • put in the location.

  • So it takes a lot of training.

  • Part of the training involves,

  • of all things, humans.

  • Robot pilots who manually control the arms

  • while the AI watches

  • and learns the finer points of grabbing.

  • All right, man, teach me how to use this thing.

  • Have a seat.

  • So you see a 3D mouse here,

  • this lets you navigate the arm through dimensional space.

  • So imagine you're holding the arm in that left hand

  • and you're just moving around.

  • Move it slowly and gently.

  • There you go.

  • I'm trying to get the Oreos.

  • I gotta go up.

  • Oh, shoot, I went too far up.

  • I want these Oreos.

  • (grunts)

  • You killed the can. You lose.

  • Come back to me arm.

  • There, success.

  • It's like being in an arcade. Basically.

  • It's like you actually get to win something.

  • Just down the hall, Kindred keeps a room

  • full of pilots doing the same thing as me.

  • Only these guys are actually competent.

  • They're remotely overseeing some arms in a Gap factory,

  • a thousand miles away in Tennessee.

  • How long have you been a robot pilot?

  • Just over a month actually.

  • I've only been here five weeks.

  • What was the training process like?

  • Almost like playing a video game.

  • It's a like shirt, done.

  • That's a backpack. That's a backpack, okay.

  • Somebody's undies.

  • Oh, there it goes.

  • One shirt at a time.

  • (calm music)

  • As the arms observed their human guides,

  • they gradually learn how to do better

  • at picking up T-shirts and shoe boxes.

  • Eventually, they'll be fully autonomous

  • and size services will no longer be required.

  • One day, this is just gonna light up

  • and it's gonna be picking the objects--

  • Pretty much.

  • Pretty much that's the ultimate end goal at least for these

  • to have it just constantly wearing and going.

  • And the people will be free.

  • The people will be free to do other more important things.

  • So he seemed kind of happy about the prospect

  • of unemployment, but I was concerned for his future.

  • Isn't there something grim about the human training there?

  • Yeah, it's not good to take people's jobs away,

  • but this kind of technology coming into the workforce

  • should make us stop thinking

  • about how we're going to pay people in the future

  • because AI is not just going to automate manual labor jobs,

  • it's gonna automate things like doctors, and lawyers,

  • and accountants very soon,

  • so I think there's gonna be issues,

  • there's gonna be a lot of disruption

  • when these things come online.

  • Suzanne is a realist, but she's also an optimist.

  • In her vision of the future,

  • robots won't be mindless competitors to humanity.

  • They'll be full-fledged citizens like the rest of us.

  • One of the crazy ideas that you talked about was

  • you've got a robot and it's working at a factory

  • and then it's gotta go, maybe it gets paid a wage

  • and it goes to buy lithium-ion batteries to keep it going.

  • Why would that have to happen?

  • I mean, if you're having a physical body

  • then you will have a lot of physical needs

  • just like we have.

  • You might have to go to the repair shop

  • to get like motor looked at or something like that

  • and they'll have to pay someone to do that.

  • I think they'll just be contributing to our economy

  • in the same way we do.

  • And if they have brains like us, they'll want to

  • explore new things they've never seen before,

  • they'll want to learn things, they'll want to perhaps rest

  • so that their mind has time to consolidate

  • all this new information.

  • I'm trying to picture it in my head

  • this little robot worker.

  • Does he go home and sit on the couch, watch TV after work?

  • I don't see why not.

  • They probably watch cat videos like the rest of us.

  • It's hard to tell sometimes if Suzanne

  • is laughing with us or at us.

  • But she's not alone in her cautious optimism for the future.

  • I think there's always a sense that technology can be

  • either used for good or used for bad unreassured

  • that Canada is part of it

  • in terms of trying to set us on the right path.

  • On the whole being responsible and thoughtful

  • about the power we're gaining by research and learning

  • is the right trend line,

  • and I don't think AI is automatically doomed

  • to some dystopian outcome.

  • We're told that politicians will come up

  • with policies that address massive job loss

  • and prevent horrific inequality between the classes.

  • And we're told that these guys will take so long

  • to become human-like that we need not be afraid for a while.

  • The truth though is that we're turning ourselves

  • over to the unknown here.

  • So, you know, fingers crossed.

  • Eventually, I think we will become the AIs.

  • We will become the intelligent machines.

  • We will understand how things can be smart

  • and we can deliberately create them.

  • So it's you might think of it as making a new generation,

  • new kinds of people.

  • Humanity is continuing to evolve,

  • and why wouldn't enhanced people or even design people

  • be the next step in humanity?

  • It's really hard to predict the future.

  • I think there's gonna be all sorts of things happening

  • we didn't expect, but there's one thing that we can predict.

  • This technology is gonna change everything.

  • Good bye.

  • Good bye.

  • Good bye. Good bye.

  • Once I power you down, that's it.

  • Yeah, that's right.

  • We'll end it right there.

  • That was getting deep.

  • That was getting really deep.
