ARCHIVAL (CLIP FROM โ2001: A SPACE ODYSSEY,โ 1968):
ASTRONAUT: Open the pod bay doors, Hal.
HAL: Iโm sorry, Dave, Iโm afraid I canโt do that.
NARRATION: If you had to pick our favorite fictional story about robots, the one where they wipe out humans keeps on delivering at the box office.
ARCHIVAL (TRAILER FOR โTHE TERMINATOR,โ 1984):
ANNOUNCER: The Terminator.
ARCHIVAL (CLIP FROM โTHE MATRIX,โ 1999):
AGENT SMITH: Human beings are a disease and we are the cure.
ARCHIVAL (CLIP FROM โEX MACHINA,โ 2015):
MAN: Ava, I said stop!
NARRATION: And recently, similar fears about artificial intelligence seem to be spilling into the news.
ARCHIVAL (BLOOMBERG, 4-18-18):
NEWS REPORT: The robot apocalypse could be closer than you think.
NARRATION: Futuristic as all this sounds, history has some insights to offer us here, because even on the news, weโve seen a version of this movie before. In the 1990โs, the media was fixated on a real life, high-stakes battle between chess grandmaster Garry Kasparov and IBM supercomputer Deep Blue.
MAURICE ASHLEY (CHESS GRANDMASTER): Everybody billed it like this was the Terminator, come to potentially take down the humans.
ARCHIVAL (ABC EVENING NEWS, 5-3-97):
NEWS REPORT: IBMโs 3,000-pound supercomputer, which can calculate 200 million chess positions per second.
ARCHIVAL (CNN, EVENING NEWS, 5-9-97):
NEWS REPORT: All the major TV networks have covered it, and itโs been beamed to 20 countries around the world.
MAURICE ASHLEY: I was rooting for Kasparov to kick its ass. Thereโs no question about it.
NARRATION: While chess grandmaster Maurice Ashley was giving live commentary on the match, Murray Campbell was rooting for Deep Blue. He helped design it.
MURRAY CAMPBELL (SENIOR MANAGER, ARTIFICIAL INTELLIGENCE, IBM): Chess was commonly considered to be a grand challenge for computer science. The earliest computer scientists said if we can get a computer to play chess, weโve really done something.
NARRATION: And in the first round Kasparov had the upper hand.
ARCHIVAL (CNN EVENING NEWS, 5-12-97):
REPORTER: He won game one versus the Deep Blue supercomputer.
COMMENTATOR: In fantastic style.
NARRATION: But Game Two changed everything. About 35 moves in, Kasparov set a trap. But Deep Blue refused the bait. Instead, the machine made a shrewder choice that paved the way to a win.
MAURICE ASHLEY: It was stunning to see a computer play like that. When you have a choice between an aggressive, sharp, tactical move that is concrete and specific, versus a subtle positional move, thatโs really where the โย the grandmaster is shown.
MURRAY CAMPBELL: Those sequence of moves showed Kasparov that Deep Blue was playing at a level beyond what he had imagined it could do.
NARRATION: A shaken Kasparov resigned about 10 moves later. In the rest of the games, Kasparov fought to a grueling series of draws until, in the sixth and final faceoff, the exhausted human champ fell apart completely.
ARCHIVAL (ABC EVENING NEWS, 5-11-97):
MAURICE ASHLEY: There was no reason for him to play chess like this. He never plays chess like this.
ARCHIVAL (CNN EVENING NEWS, 5-11-97):
NEWS REPORT: He resigned about an hour and three minutes into the game.
ARCHIVAL (ABC EVENING NEWS, 5-11-97):
GARRY KASPAROV: I have to apologize again. I am ashamed by what I did at the end of this match.
NARRATION: Media pronouncements on the outcomeโs gloomy implications were swift.
ARCHIVAL (CBS EVENING NEWS, 5-12-97):
NEWS REPORT: We humans are trying to figure out our next move.
ARCHIVAL (CBS EVENING NEWS, 5-11-97):
NEWS REPORT: Call it a blow against humanity.
ARCHIVAL (ABC EVENING NEWS, 5-12-97):
NEWS REPORT: The victory seemed to raise all those old fears of superhuman machines crushing the human spirit.
NARRATION: But computer scientists had a different reaction.
PATRICK HENRY WINSTON (PROFESSOR OF ARTIFICIAL INTELLIGENCE, MASSACHUSETTS INSTITUTE OF TECHNOLOGY): Every time a computer does some narrow thing better than a person, thereโs a temptation to think that itโs all over for us. But Deep Blue doesnโt play chess the way Kasparov plays chess. Deep Blue processes information much like a bulldozer processes gravel.
GURUDUTH S. BANAVAR (CHIEF TECHNOLOGY OFFICER, VIOME): Every slice of capability that weโve seen computers become really good at, and even superhuman at, are actually one small sort of small pieces of the breadth of intelligent behaviors that we exhibit.
NARRATION: Guru Banavar helped build the digital descendant of Deep Blue: Watson. Itโs a talking, self-teaching system, nimble enough to play Jeopardy. In fact, it became very hard to beat.
ARCHIVAL (ABC, WORLD NEWS WITH DIANE SAWYER, 2-15-11):
WATSON: Who is Michael Phelps?
ALEX TREBEK: Yes. Watson?
WATSON: What is Last Judgement?
NARRATION: So how close are machines coming to outsmarting mankind? The people working to solve some of A.I.โs toughest problems may be in a unique position to know. For example, before smart machines could run amok, theyโll need to walk. At M.I.T. in 2016, Russ Tedrake led a team of engineers designing software for one of the most advanced humanoid robots ever built.
RUSS TEDRAKE (PROFESSOR OF ELECTRICAL ENGINEERING, MASSACHUSETTS INSTITUTE OF TECHNOLOGY): The level of complexity that we can deal with is absolutely state of the art and beyond.
NARRATION: And if machines are going to walk, theyโll need to recognize whatโs in front of them. A few years ago at Stanford, Fei-Fei Li taught computer systems to describe objects they see in pictures for the first time.
ARCHIVAL (FEI-FEI LI TED TALK, MARCH 2015):
COMPUTER VOICE: A man is standing next to an elephant. A large airplane sitting on top of an airport runway.
FEI-FEI LI (PROFESSOR OF COMPUTER SCIENCE, STANFORD UNIVERSITY): Weโre really on the quest for building machines and computers to have that kind of visual intelligence that eventually can match to humans. Visual intelligence is about seeing the objects, understanding the scene, reasoning about the visual story.
NARRATION: At M.I.T., Patrick Henry Winston has been programming systems to carry out the kind of basic reasoning people use to interpret stories.
PATRICK HENRY WINSTON: What is it that makes human intelligence different from the intelligence of something like a chimpanzee, or a Neanderthal? And for me, itโs the ability to tell stories.
NARRATION: Each of these scientistsโ projects amounts to an engineering moonshot in its own right. Yet each aims to replicate just one facet of the general intelligence humans take for granted, and even as the technology improves, none of these researchers see a finish line in view.
RUSS TEDRAKE: This is absolutely one of those very state-of-the-art-machines. But it is not capable of even some of the things that weโd expect a toddler to be able to do very effectively.
FEI-FEI LI: Iโm not trying to say we didnโt work hard, and you know, we have made a lot of progress. But I think itโs important to understand we are closer to a washing machine than the Terminator.
ARCHIVAL (FEI-FEI LI TED TALK, MARCH 2015):
COMPUTER VOICE (DESCRIBING A PHOTO OF A STATUE AND ANOTHER OF A BABY HOLDING A TOOTHBRUSH): A man riding a horse down a street next to a building. A young boy is holding a baseball bat.
PATRICK HENRY WINSTON: The closer you come to doing research in this area, the more you realize how difficult everything is. We donโt know when those discoveries will come, but they look like thereโs going to be many of them, not just one.
NARRATION: And these scientists say itโs unlikely weโll see smart machines beget vastly smarter versions of themselves overnight and totally escape human control. Thatโs because these A.I. nightmare scenarios fail to grasp a paradox that underlies much of the work in artificial intelligence.
GURU BANAVAR: Things that are easy for humans are hard for computers. And things that are easy for computers are hard for humans. We underestimate all of the things that we do so easily.
NARRATION: In some ways, it comes down to common sense. We see this problem in one of the most visible applications of A.I. on the street right now. Cars owned by the Google offshoot Waymo are piloting themselves around a suburb of Phoenix, Arizona, as part of an experimental driverless taxi service. It works in part because Waymo cars follow hyper-detailed maps.
ANDREW CHATHAM (LEAD SOFTWARE ENGINEER, MAPPING, WAYMO): Our maps have, down to about 15 centimeters, the location of every curb, traffic light, stop sign, driveway, and so for a car from us to appear on your block, we need to have built a map of your block.
NARRATION: The question is what happens in more chaotic situations that call for more common-sense understanding on the road.
JOHN LEONARD (PROFESSOR OF MECHANICAL ENGINEERING, MASSACHUSETTS INSTITUTE OF TECHNOLOGY): Thereโs this sort of negotiation which has been called the social ballet of driving. How do you write the computer code that says always stop at red lights unless thereโs a man on the side of the road whoโs a police officer and is waving you to go through a red light. Thatโs a really hard thing to do.
NARRATION: Obeying a traffic cop is just one common sense task humans carry out behind the wheel, and things like this remain hard for machines. And thatโs why Waymos arenโt likely to appear soon on your block if the conditions arenโt ideal. A.I. works best on problems where thereโs a structured environment.
While some researchers worry that millions of workers could be displaced by automation, others think our jobs will simply be transformed, and one of the optimists on this issue may surprise you: Gary Kasparov.
ARCHIVAL (TED TALK, 2017):
GARY KASPAROV: Human plus machine isnโt the future, itโs the present. And as someone who fought machines and lost, I am here to tell you this is excellent, excellent news.
NARRATION: As for the question about Hollywood fearsโฆ
ARCHIVAL (โAVENGERS: AGE OF ULTRON,โ 2015):
ULTRON: Iโm glad you asked that, because I wanted to take this time to explain my evil plan.
NARRATION: โฆplenty of A.I. researchers say weโre safe from those for now.
RUSS TEDRAKE: I think you canโt watch this robot without thinking, wow, theyโve got a long way to go. We like to joke โย his batteries only last an hour, so, you know, even if he ran amok he wouldnโt get very far.

Are Robots Really Taking Over?
Humans are wary that robots could replace them. So what can we learn from the legendary chess match between a supercomputer and Garry Kasparov?
The first time the word โrobotโ ever appeared in literature in the 1920s, the fictional machines rose up and killed their creators. Weโve been telling the same story ever since. From Hal 9000 to the Terminator, it often seems the measure of a fictional machineโs intelligence is best taken by its wish to do us harm.
Itโs a scary vision for some observers, and not just technophobes: Scientists like Stephen Hawking; legacy technologists like Bill Gates; not to mention cutting-edge techies like Elon Musk, have all announced their worries about runaway A.I. killing off the human race.
Remarks like that tend to echo in the press. But how worried should we really be? Talking to the scientists working to solve some of A.I.โs toughest problems offers some answers. And so does taking a closer look at the legendaryโand widely misunderstood โ match between a supercomputer and chess grandmaster Garry Kasparov in 1997.
