ken jennings who had won millions on the program had only 200. in the second round as the questions became more nuanced and difficult the humans came back symptoms. >> you can see it struggling with some of the more ambiguous questions, but the revealing moment of the night, when it is not a genious, jennings maid the incorrect answer and. >> ken, what are the 20s, watson. >> what is 1920s. >> no. >> ken said that. >> you could hear alex trey beck saying "ken just said that." >> the humans, they came back, but they didn't pass watson, brad rutter is now tied with the machine with 5,000 points, ken jennings has 2,000, there is two more nights of this, gone two rounds, got to get through final jeopardy. we won't know until wednesday weather machine or man wins. >> it's incredible because two years ago it's impossible. you couldn't do it. >> think about all the nuances and those questions, you have to answer with a question it and it -- that machine had some awkward moments as it struggled in the later moments. >> yeah, the wording of the questions

reporter: it's the ultimate jeopardy square off, the record holder for consecutive matches won ken jennings and brad rutter taking on an i.b.m. computer named watson. >> watson? >> what is sauron? >> right. >> reporter: watson is a mega- mind of ten refrigerator-sized computer racks running at a speed of 80 trillion operations a second. but this is far beyond google. watson understands language the way we speak it. the difference between bat and bat, for instance. it analyzes the equivalent of a million books and whittles down hundreds of likely answers to the best one. >> understanding human language, being able to get into the nuance, the implicit nature of it, the ambiguities actually are very, very hard problems. >> reporter: the scientists here have filled watson with so much information it would take the typical human being 250,000 years to learn as much. but as the competition has proven so far, that makes watson smart-- not perfect. >> what are the '20s? >> no, watson? >> what is 1920s? >> no. ken said that. >> reporter: after the first of three nights, watson was tied for the lead

champs, ken jennings and brad rutter, again wednesday night.t, watson earned $77,000 versus $24,000 for jennings and $21,600 for rutter. >> i think we both got a taste of what it might have been like to play against us. >> reporter: this is how the computer worked. when show host, alex trebek, delivered a clue, a text of the clue was sent to watson, who searched his hard drives for the answer. a long way since that first computer with a hard drive in the '60s which could store one manhattan phone book. watson can hold 12 million of them. in the '80s, ibm's first pc could understand 5,000 words. watson, 125 billion. still, trebek is only impressed up to a point. >> i said, when you can develop a computer that can come up with original thought, that can make me laugh and that have emotion, then i'll stare worrying. but that's a long way down the line, folks. that will take a while. >> reporter: t.j. winick, abc news, new york. >> despite the victory, watson's main creator says he sees human intelligence consuming machine intelligence, and not the

. >>> "jeopardy" champions ken jennings and brad rutter have one last chance to redeem themselves tonight. they were literally crushed in the second round of "jeopardy's" man versus machine challenge. watson finished the game with a $25,000 lead. but the computer did miss final "jeopardy." the topic was u.s. cities. but watson gave the response, toronto. it was a pretty bad night for the humans. only 5 out of 30 questions answered correctly. >> i have a feeling watson has a pretty quick trigger finger also. >>> coming up on this wednesday, bernard madoff's first interview. >>> plus, some swear it's a cold killer. dr. richard besser weighs in on the use of zinc. >>> and the klepto cat, who has a habit of stealing from the neighbors. craves fuel. make sure you give it something that counts. i love quaker oatmeal, it's seriously a superfood. it's fuel that your body needs to get going. this stuff is a game changer. and now it's better than ever. it's got a heartier texture, and in some of your favorites, all natural flavors and 25% less sugar. i can't think of a better way to kick off your d

watson netted nearly thirty six thousand dollars in prize money and its two human competitors ken jennings had forty eight hundred dollars and brad rutter had a little more than ten thousand dollars so basically it was a rout the computer made a killing but i guess that we should lose all hope not feel completely useless just yet because watson did have a few problems including a big stumble in final jeopardy and the category was u.s. cities and the answer was its largest airport is named for a world war two hero its second largest for world war two battle and both jennings and rutter correctly answered chicago but not so much for watson now who are leader watson going in the final thirty six thousand six eighty one and the response was what is to wrong too with a lot of question marks which means of course that watson had many many doubts and the wager how much you're going to lose all you see right. now watson the answer of toronto set off a firestorm of questions and suppositions on twitter and other sites as to how the i.b.m. machine could possibly come up with an answer so out of left

supercomputer question answering machine watson now ken jennings even wrote i for one it welcome our new computer overlords it's incredible stuff an artificial intelligence for a computer to understand respond to the human natural language and it can also be a scary one how long until your job is replaced by watson's offspring and i.b.m. has announced they're already planning on creating a position as a system service where doctors can ask questions to a cybernetic assistant there also discussion to create a version of watson that would be able to interact with consumers on subjects like buying decisions and even technical support to house a new computer age officially arrives where you want to discuss it is chris wilson associate editor at slate purse thanks so much for being here my pleasure you know this is kind of incredible kind of demoralizing or hard saying i think i want to do it and it was mostly exciting was there anything out there that really shocked you in watching this watson versus man competition on jeopardy sure the thing that shocked me really was that jeopardy goes

well -- >> i'm not ken jennings but -- >> jimmy: best of luck. remember, it's very easy.ve to get his chest waxed. all right? >> sounds good. >> jimmy: simple enough. let's take a look at tonight's category. we've got latvian prime ministers. [ laughter ] 13th century south american architecture. [ laughter ] much ado about quantum mechanics. [ laughter ] you'll notice, quantum mechanics is in quotes. moving on, the 1520s. [ laughter ] other lesser-known latvian prime ministers. [ laughter ] and, of course, potpourri. [ laughter ] feeling good about these categories? >> yes, definitely. >> jimmy: all right, he's feeling good. all right, let's get started. as per the rules of the game, i will be choosing the categories for you. [ laughter ] so, let's start off with latvian prime ministers. ready? here we go. this founder of the latvian farmers union was elected in 1918 and was later succeeded by zigfried anna meierovics. audience, no helping. it's all riding on you, what do you think? >> i'm going to say who is president obama.

[ laughter ] i made that up, too. i made that part up, too. [ laughter ] >> no, that part's true. >> but there are people trying to kill him. >> this is all his reality, so you don't know what's real or what's not real. so, that's an amazing setup for the clip. >> jimmy: yeah, 'cause i'm so excited. i love these movies. there just like a real good story movie. >> it's like "taken," or "borne identity' -- i mean it's like a really fast -- it's fun. >> jimmy: i love it so much.

ken jennings won 74 consecutive games brad rutter earning $3 million in prize money but watson isn'ttecture. that is a mouthful but it's taking that clue and that category and this surrounding clues like z.understanding it for many different dimensions. >> they played a demo round for the media and watson didn't hold back. >> for jennings playing "jeopardy" is old hat. but playing against something the size of 10 refridge yaitors? >> i never picked up a buzzer it turns out to be like playing a very good human player. you've got to know your stuff. but kit be beat. it turns out. >> always bet on humanity. >> rutter didn't let on he was intimidated. >> there is a bit of having to strike the blow for humanity here. and... from the rehearsals we've done in the game play watson is just a really good player. it's kind of the same thing. i guess there is extra pressure having to represent humans against machines. >> the host isn't intimidated and he's seen all kinds of contestants. >> i think an intriguing thing about this with this is where do we go from here. how do we follow this? i'm su

the human brad rutter has a little more than $10,000 and the other human ken jennings is in third with800. the final round is today. >> the other human. >> yeah. they're lagging. >> the computer is so quick. i mean, the minute the question pops up -- >> we still have lawrence. we need lawrence. >> with the weather. >> it's the weather around the bay area, folks. what a morning to wake up to. it's been stormy. the ends with have been howling outside. and the rain has been dumping in spots. we are getting on the back side of this cold front just a bit. we have cells popping up on the back side through martinez and orinda. in berkeley rain falling there right now and there is more on the way. you have this very cold, unstable air that's coming in behind this cold front now. so yeah, cold showers and the possibility of some isolatedd thunderstorms. saturday morning leftover showers, looks like we'll dry outcome sunday, more rain the beginning of next week. elizabeth has traffic. traffic coming into san francisco. >> if you are coming up 101 from the peninsula the connector ramp to 280 is s

will run part of one of a three-part series featuring the watson computer versus jeopardy champs ken jennings expert katie linendoll to ibm headquarters in new york to challenge watson. hey, katie. >> yeah, save myself some real humiliation. here is a chance for me to combine my two favorite things i'm a tech geek and a jeopardy freak. the computer, who is boss? with its 9 million daily viewers jeopardy is one of the most popular game shows in america. and it's been a pop culture icon for more than 45 years. but would you believe that the best jeopardy player of all-time might only be four years old? >> what is buffalo, new york. >> that is correct. >> meet watson. a super computer designed by ibm to be the ultimate jeopardy playing machine. >> the computer is capable of tens of billions of operations per second. >> we've got ten racks -- >> reporter: the doctor and dozens of researchers started building watson in 2006 and fed its brain with all kinds of information. >> encyclopedias, dictionaries, the bible, shakespeare's plays, classic books and novels. about a million books. >> reporter: i

the machine won more money than ken jennings. researchers can also take a bow because they created watson's brain. the program says that machine represents a break through in the computer's ability to understand the human language. ibm is sending that super computer now to a number of university hospitals for field testing. it will assist doctors in processing large amounts of data. but hospital officials say unlike jeopardy where there's one clear-cut answer the medical field can often have multiple diagnosis and solutions. so that's different. and we should point out during the competition wattson a couple of times got the answer wrong. the human would say the wrong answer and he repeated the same one. he didn't understand and repeated the same answer. it is not perfect. >>> 5:20. the brainiest city in america is not here. we'll take a look at the new list at which bay area cities were left off. >>> and apple's ceo steve jobs is back in the public. what right does the public have about his health? >>> plus a bay area police off

. >> it seems to be outperforming ken jennings though who won a record 74 consecutive rounds of jeopardythat's why he's back doing this. after one of three rounds jennings had $2,000 to wattson's $5,000. the other human, brad rutter is tied with wattson. the event wraps up tomorrow. >>> taxpayers will pay the clean up bill for a san francisco valentine's day tradition. >> our job is to keep the city clean. and we don't have any resources that we need. and having this extra burden just makes it harder for everyone. >> huge pillow fight. this one at justin herman plaza drew hundreds of people. last year took two days and $35,000 to clean up the mess left behind. but last night the city got some help from a nonprofit group. pillows for puppies say they collected 150 garbage bags full of trash and 300 pillows. they'll be donated to the puppies at homeless shelters. >>> pillows for puppies. >>> they put their lives on the line for america, but this morning they are homeless. what's next for war veterans on the peninsula after a fire chased them right out into the streets? >>> plus will berkel

and if you watched it, you saw ken jennings because he knew the answer to almost all the questions but just went right in. >> but it's like one of the scientists said the other day, you have this huge super- computer, people working for years on it, and it competes against a guy who had a sandwich last night. so -- >> that's true. [ laughter ] >> but they kind of use it to help in medical -- > yes, diagnosis and do a bun of things. >>> 5:55, we have our doctor of weather down in the weather center. lawrence, what's happening with the storm? >> we have those showers continuing outside. saw some lightning strikes coming in this morning so you get an idea that air is very unstable over head. right now the heavier amounts of rain focused to the north bay. you can see moderate and heavier amounts in this area. kind of catching a break in parts of the peninsula. the south bay showers in towards san jose. but a bigger batch of moisture off the coastline likely to get rain going, on and off heavy and pockets of thunderstorms, and maybe even some isolated hail. cold enough for snow in the mount

. >> so far it's out performing the great ken jennings who won a record 74 straight rounds of jeopardy. jennings is just $2,000 while watson and the other human contestant have $5,000 each. jeopardy will hold three rounds to decide who is the smartest. >>> barry bonds' perjury trial finally set to begin in just five weeks. lawyers are now playing hardball. both sides are now focused on bonds' ex-mistress kimberly bell. prosecutors want her to testify about bond's alleged rage and physical changes. feds call her an unreliable witness who tried to cash in on her relationship with barry bonds. >>> we have learned this morning that it took six hours to clean up the remains of what's become a valentine's day tradition in san francisco. we spoke with the department of public works just about an hour ago and they say it costs $8,000 to clean up the feathers left behind by last night's pillow fight in justin herman plaza. last year there were more people it cost $35,000 to clean up. this year a nonprofit group tried to lend a hand. pillows for puppies collected 150 garbage bags full of trash a

so when we look at ken jennings and brad rutter, we're impressed by what they know. but for the i.b.m. team, it wasn't encoding all of that knowledge that was a challenge, it was figuring out how to use natural language. so there uz there's things about "jeopardy" contestants that we take for granted turn out to be a lot of the challenge. so i think in some ways these contests throw a lot of interesting light on what's impressive about being a human being. >> rose: is watson significantly more powerful than the kind of computer that most of us use? >> oh, absolutely. yeah. >> it's an entire system that's taken four years and $30 million to build. all geared towards one single task, if you like, and there have been 25 to 30 ph.d.s working on this, some of the smartest people in their fields in the world. so you can imagine all that brain power brought to bear on playing one simple quiz show that gives you a sense of how far they've gotten. they've had to make break throughs not just in writing algorithms, the sort of basic tasks that term how this computer work but al

second place is ken jennings. he had the longest winning streak at 74 games.t of the first round will be showed tonight with a second round on wednesday. the winner gets $1 million. i'm not sure how the computer would spend it if it wins. maybe an upgrade to the hard drive. >>> 5:55. we are tracking the forecast this morning because rain is moving through again today. christina has the latest. >> good morning to you. it is not fair that watson gets to do a google search to find out the answers. i think that whole situation is rigged. not like our forecast. it is pretty well laid out for us. we have a lot of rain each and every day. all the way through this weekend. the most moisture we are expecting from the series of systems that will pass through the bay area will come through over the course of tonight into tomorrow. this is our weather maker. a big system of low pressure. this is what passed through the area yesterday. you can see it is weak in comparison. and you can see a lot of the showers fall apart as they make their way through the los angeles area i

champs ken jennings and brad rutter again wednesday night. ournament, watson earned $77,000 versus $24,000 for jennings and $21,600 for rutter. >> i think we both got a taste of what it might have been like to play against us. >> reporter: this is how the computer worked. when show host delivered a clue, a text of the clue was sent to watson, who searched his hard drives for the answer. a long way since that first computer with a hard drive in the '60s which could store one manhattan phone book. watson can hold 12 million of them. in the '80s ibm's first pc could understand 5,000 words. watson, 125 billion. still trebek is only impressed up to a point. >> i said when you guys develop a computer that can come up with original thought, that can make me laugh and that can have emotions, then i'll start worrying. but that's a long way down the line, folks. that will take a while. >> reporter: t.j. winick, abc news. >> sad day for humanity. we could test our viewers. >> we have a little question for you. >> there we go. most popular dual-anchor ove
