♪ ♪ president george h.w. bush began his last journey early today atp the u.s.ol, accompanied by the bush family, and the melancholy chords of the u.s. navy band that set the tone on this national day of mourning. the 41st president's casket was driven through the heart of washington, passing by the whit housfinal time, and ultimately, arriving at washington national cathedral, for the invitation-only funeral. outside, onlookers lined theet stto pay their own respects. >> president bush was my commander-in-chief when i was in the military.ju so it wa fitting for me to come out and say goodbye to him. >> you have to show honor to ings that matter. and mr. bush mattere so this is my way of saying he mattered in my life.

a woodruff: inside, a rare gathering of leade luminaries, led by five formerts presidcabinet secretaries, senators and several supreme court justices. over the next two hours,hey celebrated george h.w. bush with praise, humor and at times, tears. presidential historian jon meacham recalled the moment that history might have taken a very different turn, when a young navy pilot was shot down over the pacific, during world war two. >> the future 41st president of the united states, was alone. sensing his men hadn't made it, he was overcome. he felt the weight of responsibility as a nearly physical burden. and he wept. then, at four minutes shy of

noon, a submarine emerged to rescue the downed pilot. george herbert walker bush was safe. 'se story, his story and ours, would go on by grace. through the ensuing de president bush would frequently ask, nearly daily-- he'd ask himself why me? why was i spared? and in a sense, the rest of his life was a perennial effort to prove himself worthy of his salvation that distant morning. >> woodruff: mr. bush, meacham said, famously kept a frenetic pace, from speed golf to cigarette boats, and even, to campaigning. >> he never slowed down.

on the primary campaign trail once, he grabbed the hand of a manikin asking for votes. when he realized his mistake, asked, never know.to gosk. >> woodruff: meacham called mr. sh "america's last great soldier-statesman," presiding over the fall of the soviet union, and rallying a coalition to fight the first gulf war. >> he stood in the breach in the cold war against totalitarianism. stood in the breach in washington against unthinking partisanship. he stood in the breach against tyranny and discrimination. and on his watch, a wall fell in berlin. the george herbert walker bush, who survived tery fall into the waters of the pacific three-quarters of a century ago, made our lives and the lives of nations freer, better, warmer, and nobler.

that was his mission. that was his heartbeat. and if we listen closely enoug we can hear that heartbeat even now, for it's the heartbeat of a lion. a lion who not only led us, but who loved us. that's, why him. that's why he was spared. >> woodruff: the funeral drew world leaders past and present, including former canadian prime minister brian mulroney, whose term in office overlapped mr. bush's vice president.nt and he recalled one of their first tocounters. >> at his first eeting in brussels, as the new american president, he sat opposite of me actually.

that day george was taking copious notes as heads of government spoke, ending only when the secretary general of nato firmly decreed a coffee break. george put down his pen, walked over to me and said, "i just learned fundamental principle of international affairs." i said, wh's that george? he said, "the smaller the country, the longer the speech"" >> woodruff: mulroney had special praise for t late president's dealings with canada, including the trade al ultimately signed by president clinton, and more recently, rejected by president trump. >> president bush was also responsible for nafta, recently modernized and iroved by new administrations. which createthe largest and richest free trade area in thehi

ory of the world. >> woodruff: but aside frome policy, rmer prime minister remembered a friend, and labor day weekends at the bush family home in kennebunkport, maine. >> he led me down the porch to the side of the house that fronts the ocean and pointed to a small simple plaque that had been installed just some days earlier. it read c-a-v-u. george said, "brian this stands for "ceilinand visibility unlimited" when i was a terrified 18-19 year o pilot inhe pacific, those were t words we hoped to hear before takeoff. it meant perfect flying. and that's h i feel about our life today. c-a-v-u. everything is perfect.

we couldn't have asked for better lives. we're truly happy and truly at peace." >> woodruff: former wyoming senator alan simpson was likewise a close friend of mr. bush-- a bond forged through decades together in washington. >> and he was a man of such great humility, those who travel the high road of humility in washington, d.c. are not bothered by heavy traffic. >> woodruff: simpson fondly recalled nights that the two men and their wives spent together, enjoying plays and music. >> the four of us went to see thmichael crawford, singin songs of andrew lloyd webber. all four of us were singing when we went back to the white hous"" dont cry for me argentina" and tidbits from phantom of theot opera anr magic of webber, y d a few days later he's getting hammerede press

for some extraordinarily petty bit of trivia, and sdenly he simes out, "don't cry fo argentina" the press then wrote that he was finally losing his marbles. >> woodruff: the famed simpson wit elucidated the man he was mourning as someone who loved a good joke, but, who was so much more, as well. >> he never lost his sense of humor, humor is the universal solvent against the ab elements of life, that's what humor is. he never hated anyone. he knew what his mother and my mother always knew; hatred corrodes the container it's carried in. the most decent and honorable person i ever met was my friend george bush. one of nature's noblemen. >> woodruff: perhaps the mostig

pont moments of the day came when the 43rd president, george w. bush, rose to deliver his own eulogy. he mixed humor and pathos, recalling a father of boundless ergy, and a zest for life. >> at age 90, gerage h.w. bush uted out of an aircraft and landed on the grounds th st. anne's bsea in kennebunkport maine. h the church whe mom was married and where he worshipped often. mother liked to say ti chose the lo just in case the chute didn't open. (laughter) in his 90s, he took great delight when his closest pal james a. baker smuggled a bottle of grey goose vodka into his hospital room. apparently it paired well with steak baker had delivered from morton's. to his very last days, dad's

life was instructive. as he aged, he taught us how to grow with dignity, humor and kindness. and when the good lord finally called, how to meet him with courage and with the joy of the promise of what lies ahead. >> woodruff: the formerpr ident likewise paid tribute to his father's famous appeal for a kinder, gentler nation, and his call to volunteer. >> dad taught us that publicob service is and necessary. that one can serve with integrity and hold true to the important values like faith and family. he strongly believed that it was important to give back to the hicommunity and country in one lived. he recogzed that serving others enriched the givers' soul. to us, his was the brightest of 10 points of light. >> woodruff: but the late prident faced darkness ear

in his family life: the loss of his daughter, robin, to leukemia. >> jeb and i we too young to remember the pain and agony he and mom felt when our three- year-old sister died. we only learned later that dad, a man of quiet faith, prayed for her daily. he was sustained by love of the almighty. and the real and enduring love of her mom. dad always believed that one day he would hug his precious robin again. >> woodruff: ultimately, the 43rd president painted the 41st as a public man of distinction and a private man of w leaving a family to grieve a father, grandfather and great grandfather. >> he was firm in his principles and supportive as we began to seek our own ways. he encouraged and comfortebut never steered. we tested his patience. i know i did. (laughter)

but he always responded with the great gift of unconditional love. last friday, when i was told he had minus to live, i called him. a guy answered t " phone and sathink he can hear you but he hasn't said anything for most of the day." i said, "dad, i love you and eru've been a wonderful fa and the last words he would ever say on ear were "i love you too." through our tears let us know blessings of knowing and loving you. a great and noble man. the best father a son orug er could have. (crying) and in our grief, let us smile knowing that dad is huggingn rod holding mom's hand again.f: >> woodrhe rector of the bush family's home episcopal church in houston was at the esident's bedside in his final hours.

sell levenson delivered the homily today. >> it was a beautiful end. it was a beautiful beginning. for a moment, but a moment only that dint of light we know as george herbert walker bush dimmed. but it now shines brighter than it ever before has. mr. president, mission complete. well de, good and faithful servant. welcome to your eternal home where ceiling and visibility are unlimited and life goes forever. >> woodruff: the service concluded with famed irish tenor ronan tynan singing the lord's prayer.

>> ♪ lead us not into temptation ♪ for thine is the kingdom >> woodruff: and, the nationally televised service funeral came to a close. >> let us go forth in the name of christ. thanks be to god. >> woodrf: with the benediction, a slow procession carried the flag-draped casket from the cathedral, toting motorcade. a departure ceremony followed at joint base andrews in maryland, including a 21-gun salute. and then, president george h.w. sh left washington for the last time. the casket was flown to houston, where mr. bush will lie in a repose overnigst. martin's episcopal church. l ere's a private service tomorrow, with bur follow, alongside his wife barbara andug er robin on his presidential library grounds at texas iversity in college

station, tex. >> woodruff: just moments ago, the plane that has been dubbed "air force special miss1,n 4" landed in houston with the bush family to bring president bush, 41, home for thifinal time. the plane has landed. these are live pictures coming in fm houston, from the airport there, where the plane has landed and they will wait watch as he goes home. anme joinino reflect on the legacy of president george h.w. bush are "new york times" columnist maureen dowd, presidential historian michael beschloss, bush family friend, david bates, who worked in the bush 41 white house, and our margaret warner, now seniort

fellowle university's jackson institute for global affairs. hello to all of you. what a day it has been. i have to say, it was a state funeral,s ut it wasrsonal to me as any official thing i've ever seen. there were accolades. there were humor. and there were tears. earsan i was wiping away t here at our-- at our anchor desk. maureen dowd, what did you take away today? >> well, judy, it was heartwarming to see w.'s incredible emotion toward his father. but it was also kind of heartbreaking because, you know, i've spent decades covering the family, and the father, you know, consttly worried that dick cheney andond rumsfeld were leading w.positive astray on the iraq war, and the neocons were leading him astray, and i

think w. did not want to seek his father's advice or hear what he had to say about the invasion iraq. and then it took years and years before he came around and realized his father was riganht distanced himself from rumsfeld and cheney. but by that time, it was too late. it was the worst mistake in american foreign policy. to, you know, to see all tha emotion, you just wish that, you know, they had been more mentor and protege during the time they needed it. >> woodruff: a lot of complex strands run reriewg that tionship and his relationship with others in his family. margaret warner, you also covered him as a candidate. you've covered-- youe known the bush family. did they capture they complex of george bush. today. >> i think it's very hard to capture the full complexity. i mean, thenecdotes were wonderful. i think what, perhaps, didn't aome through is he was als man of great ambition.

i he was very humble. i reported a long cover story for "newsweek" years ago about how that came to be, how s mother would say, "i don't want to hear more about the great 'i ami' and his father, the grade he claird about does not claim more than his fair share of attention. on the one hand, hard to put himself forward. on the other hand he was very ambitiou and he set his sights for something, and just as on that plane, he was determined to get there, eveafter losing in '7 i'08y and as a candidan his own right. >> woodruff: david bates, you know the family going back many years. you worked for him on several of his campaigns. you were in the white house when he was there. did you see-- did the george bush you knew come through? >> yes, i did. i-- i-- i thought it was a wonderful service.to me, there was a great feeling of love in the-- in the cathedral. and i think that was appropriate because he is a beled figure.

and i thought each speaker offered a uniquperspective on his life and character. and i thought it, as difficult as it s to capture a life, as maaret said, of someone as complex as he is and a life so full as his, i thought-- i thought each of the-- each of the speaksers did a very good job of kind of encapsulating his life and character. odruff: michae beschloss, you pay attention to a lot of presidents, how does remembering this one compare to what you remember of how we've reflected on ando honored er presidents? >> well, i think, you know, every generation looks at aid prt a different way. and one thing that i love aboth is the george bush that we've all been talking about during the last four days or so is very different from the ergeorge bush that people e talking about in january, 1993, wh he was leaving office, and they were talking of him as out

of touch. many people were saying inept president, shown by fact that e couldn't even manage to win a second term. smanager of the economy. yes, he did end the cold war, but we don't care about that anymore in 1993. 25 eryears layou look back and see not only were theseri great hisl achievements, but we see qualities in george bush that were not appreciated at the time-- the modesty, the abity to reach out to the other side, to try to include you know, every generation, as i say, looks for different thingse from adent. here we are in the age of donald trump, a very confrontational politics, and the politics ofh george bems like something that was light-years ago but perhapmay one day come back. >> woodruff: maureen dowd, michael remineses us what a painful loss of that in the '92 election, when he lost to bill clinton. you wrote this week about your

wonderful correspondenh him, being in touch with him over the years. how did he work his way through that? >> oh, think that was-- you know, that was very hard for him to astake because he at 90% after, you know, the persian gulf war. and then, oneay in the press office, he sort of admitted that he h n interest in domestic policy. he really just l bing in that, you know, global club, mostly men's club. and he really didn't want to deal with the domestic side. and i think he kind of missed the moment where americans weres getting anxabout, you know, the economy and other things. and he just really gloried in the foreign affairs part of it. >> woodruff: but then on-- then, as we were saying, i mean, he lost, but he managed to livue a flife after that. and you, pigain, in that ece you wrote this week, you captured a lot of that. i mean theumor came back, the

zest for life came back. >> well, i think michael's right, you know, when we look at it through the prism of donald y trum know, one way to look at it is bush sr. would drop the first-person pronoun, the personal pronoun, because his mother always told him not to use the big "eye," not to gloat. so he would start sentencing like the danaarver imitation, "can't act, just have to be me." he would drop the "i," and now we're livingn this world that's all about the "i" with donald trump.wo the wholld is having to pivot to trump's narcissistic "i." and, you know, one heartbreaking thing was when-- in bush's book of letters, he wrote a letter ta his son he said, "if you

ever need to distance yourself from me when you'r running, don't feel bad about it." >> woodruff: margaret warner, you were parof a story that lives in history. agu wrote-- you were a reporter for "newsweek" mine, and you had done a lot of reporting about his campaign in the 1980, when he was running for president. and your editor at "newsweek" gave it the title "the wimp factor." >> "fighting the wimp factor." >> woodruff: "fighting the wimp factor." tell bus that and his reaction to it. >> what i had spent almost a year doing and speaking to every member of the family, wasatrying to gehy this person, this man who wass courage his day, as a young man who achieved so much, that there was this image problem, that the was his own man. he didn't want to separate n, andf from ronald rea so on. and i really got, i think, at the nub of h character, including the self-effacement, and why he nevers usee word

"i." and because i think "newsweek," they just wanted to jit up, they wanted to make a splash-- >> woodruff: we' never no, i don't mooez news media to do that. >> never happens. >> it came out the day he announced. and it was just devastating to the familu his ghter, doro, who spent time with me, burst into tears. in any event, he then-- so i was in agony about it because i did feel it was cruel and gratuityos. ly onee to him and amazi day at home he called me, and i don't actually recall every detailbut i do recall him saying, "there's one person in this household who won't forgive and forget. bar." >> woodruff: his wife, barbara. >> his wife, barbara bush. >> woodruff: david bates, we're trying to capture in just a few minus again the complexity of this man with the humor, you know the fact that almost died when he went into the pacific. what jon meacham was remembering

today. and yet, in the end, he did a lotsresident. i mean,s he was only there-- not only-- he was there for four years. but there was-- he was managing a foreign policy at a time when durope was it's world was changing at the f the soviet union. i mean, he managed to pull off o >> he was a very consequential president. and i think secretary j baker said it-- said it best, and he's certainly best one-term president the country has everd. and-- and-- and i agree with him. he's one of the most outstanding presidents we've ever had. he had-- his record on foreign policy is well known to many, ending the cold war without a shot being fired, which is unique in history. reunificat was-- which was opposed by most leaders of western europe. we know-- we know about the first gulf expwar how successful

the diplomacy was i but on the domestic side, clean air t amendments, which essentially endded aci rain, which was-- which was a very itical problem before that. americans with disabilities actu which reall disabled people into the mainstream of society. and a very, very tough spending control piece of legislation, which also had, as senator simpson mentioned, some revenue increases. >> woodruff: do you think he recognized what he was getting done? >> i believe that by the-- it-- in '92, in '92, after he lost, he may not have-- he n mayot have been recognized, you know, how-- how successful his presidency was. but i do think that-- and senator simpson alluded to it-- that with some years looking back on his presidency, i think

he was very, very pleased with-- with how-- how his-- and the loss was-- the loss was very, >> woodruff: it was tough. >> in a way, i don't think hisav sons wouldbeen elected governor of texas and florida or his son been elected president if he had won a second term. so. woodruff: michael beschloss, we're asking historians how do presidents weigh compared eto on another. it's too early, but what do you say now? >> well, during those four years with 2020 hindsight the one thing i'd want from a president in that he makes the right decisions about ethe cold war. he built this relationship with gorbachev, made gorbacfeel that bush would not exploit him if gorbachev opened the berlin ll, let eastern europe go, let germany reunify within nato.us georgemade some mistakes. he was not a perfect man. one thing thait drves me crazy is that he did not do what effective pres is he couldn't explain to americans when he was making

unpopular decisions. effective presidents can surmount that. but sum it all the one thing i'd want from him is what he did on the cold war. no one else who could have plausibly been president could have done that, so i think that qualified george bush to be thought of as at least a near-great president and certainly a consequential one. >> woodruff: maureen dowd, quickly, itioned the piece you wrote this week reflecting on your long correspdence and lationship with him, reporter, politician, capture for us how that went. i mean the line, "the con effecto." i can't do justice to some of the language you used. well, he just ws trying to agonize-- he would say, "dr. freud, dr. young, dr. phil, help me." you know, he didn't understand how he couldn till maintaithis correspondence with me when i was being so hard on his son. but he, as margaret has pointed out, he was capable of great

decency and forgiveness. and, you know, we just hadhis wonderful correspondence for decades. d, you know, he was a very special guy. >> woodruff: musgaret, quickly, remembering him? >> i agree with mreen completely. there was this core, this decency, and warmth ad graciousness about him that really comes through. and the letters to maureen and back, very much-- but i also agree with michael that i covered that wle period at the end of the cold war, and also the gulf war, and that could have never been brought together, that coalition-- i was with jim bakeries he went all around to try to put that together-- if iteren't for bush's personal relationships with these world leaders. and then, of course, later his willingness to end the war en he did. >> woodruff: in just a few seconds, michael beschloss, we'll still be talking abo him years from now. >> i think we will. and the great thing about history is it's tan argum without end, so if you'll invite

us back in 30 years we'll d m thre. >> woodruff: that's a promise. you'll all be back. >> thank you. >> woodruff: michael beschloss, maureen d bates, margaret warner, thank you. >> thanks, judy. >> thanks, judy. >> woodruff: turningo the day's other news, u.s. markets were closed for the bush funeral, but overseas markets fell again, on continuing confusion about u.s./china trade tensions. on twitter, president trump tried to allay the doubts, saying, "not to sound naive or anything, but i believe president xi jinping meant every word" their saturday meeting. beijing said today it will abide by a tariff cease-fire, but it gave no details. the esident was silent today on the news that former national security advisor michael flynn has given substantial cooperation to the russia investigation.

special counsel robert mueller's office described flynn's aid i a heavily-redacted court filing last night. it recommended that heot serve any jail time. flynn has admitted lying abo his conversations with the russian ambassador, during the trump transition. russian president vladimir putin is warning the u.s. against pulling out of a 1987 arms treaty. the trump administration announced yesterday it will begin that process in 60 days, if russia continues its alleged treaty violations. in moscow, putin denied any violations. he said russia will react inif kindhe u.s. starts building missiles that are now banned. >> ( translated ): many other countries, like a dozen, i think, produce such weapons. while russia and the u.s. havere ricted themselves. it looks like the american side have now decided that the situation had changed so much w that the u.sell has to have such weapons. and what will our response be?

very simple: we will do the same. >> woodruff: the 1987 treaty aimeto eliminate u.s. and russian short-range missiles the warr set to begin peace talks in stockholm, sweden tomorrow. delegates fromhe houthis, a shiite rebel faction, arrived late tuesday. members of yemen's government- in-exile arrived tod for the first talks in more than two years. a saudi coalition of sunni arab nations has been fighting the irann-allied rebels since 2015. french president emmanuel macron has scrapped a proposed fuel tae hat sparked the most violent protests in decades. his government initially said it would suspend the tax for six months. tonight, macron's prime minister said the tax is a dead letter, and he called for dialogue with protest groups. european police arrested at least 84 suspected mobsters today in raids across italy, germany, belgium and the

netherlands. they targeted an italian mafia syndicate known as the 'ndrangheta and accused of cocaine trafficking, money laundering and other crimes. at the hague, italy's top anti- maosecutor said the raids are just a small step in taking down the group's vast network.>> translated ): i wanted to underline once again, how 'ndrangheta has e,lls that operooperating amongst each other and in a network that covers the whole of euk pe. if we th have dismantled 'ndrangheta with this operation, we a certainly, we are wrong. >> woodruff: today's raids followed a two-year investigation. in addition to the arrests, police also seized more than $2 million. there's word that global carbona emission reached new records in 2018, rising the most in seven yea. an international scientific group, the global carbon project, makes that projection, based on figures from the u.s.,

china, europe and india. the findings mean some goals o the 2015 paris climate accord may be nearly out of reach. back in this country, wisconsin's republican- controlled legislature voted early today to weaken the powers of the incoming governor and attorney general, both democrats. the lame-duck session also blocked governor-elect tony evers, from overturning medicaid >> the will of the peoen officially been ignored by the legislature.ho four of us won races. the people of wisconsin expect better from us as leaders then to pit people ainst each other. >> woodruff: the measure would bar the newly elected attorney general from withdrawing the

in georgia, republican brad raffensperger won a runo tuesday for secretary of state, brerseeing elections. fellow republican kemp held the position before being elecd governor last month. he has denied using his office . suppress minority turno raffensperger says he ll continue strict enforcement of voter i.d. laws and purges of inactive voters. still to come on the newshour: newly released documents reveal that facebook shared valuableus data with select advertisers. and could robots become our newest co-workers? a look at how artificial intelligence is being used in hospitals, and much more. >> woodruff: ever since news first broke that a political alnsulting firm, cambridge

ica, was able to get data from 87 million facebook users, there have been more questions about whether facebook sold orat sharedwith other companies than it has let on publicly. that investigatiin has been cong in europe. today, as nick schifin tells us there w documents that show the social media giant gave other companies select accesto users data >> schifrin: judy, the documents were released by a british parliament committee and seem to show facebook using all of our data as a bargaining chip to increase revenue. thcommittee accuses facebo of cutting special deals with companies like netflix, trbnb, and lyaccess users' data because those companies were advertising facebook. facebook restricted access to users' data to companies iet deemed as coion. the data we're talking about is users' education and religious background, also preferences- what users like, and don't like. this matters because facebook claimed to have restricted access to this data to all

companies in 2015. and it matters becauseises questions about facebook's interest in collecting your data, and making money. for the record-- the newshour works with facebook on some video to talk about this, i'm joined by the "washington post's" silicon valley correspondent elizabeth dwoskin. thank you fonebeing with the hour. let me start with these internal discussions in 2012, and we now have these emails. facebook was figuring out how to make money. mark zuckerberg writes the following in october 1212: does that show zuckerberg thinking about users' data as some sort of bargaining chip? >> i think it does. you have to see the big picture here. this is right after facebook has gone public, and the media sto they can't pivot to mobile? are they going to make money? their stock prices dropping. so they have at the time this whole developer com know, tens of thousands of

apprentices that are literally riding off the social graph. it,obama campaign did cambridge analytica did it. and they're looking and saying, "we need to mak so they're looking at these relationships with thousands of developers, and you can see this intense bargaining that's going on beten zuckerberg and facebook's top brass over who should get access and how while at the same time, what they're publicly telling developers is th all the access is free and neutral. d this runs up until-- this debate runs through 2015 when they finally decide 2014, 2015, ey finally decide to cut off access. but what we're learning is actually there were whole atngratulations of exception the time. >> so let's fast forward to 2018. mark zuckerberg is in front of congress. this is april, and he is speaking in reponse to a question from dean heller, republican of nevada. let's take a look. >> well, senator, once again, we

don't sell any data to anyone. we don't sell it to advertisers and we don't sell it to developers. what wdo allow is people to sign into apps and bring their data, and it used to be theata of some of their friends, but now it isn't with them. is and i think that makes sense. that's basic data rtability. you own the data, you should be able to take it from one app another if you like. >> schifrin: do the documents show while facebook didn't sell data, they used the data to make money? >> the documents strgly suggest that. now, the caveat is we are seeing bits and pieces in the documents. it's not like it's a full triment of everything facebook ever did. but from what we can tell, it's interesting, privacy didn't come up that much in the. itas all about competition, business decisions. and one of-- one piece of t documents that was interesting is there's this point where they talk about how they're going to cut off all developers, unlesse thevelopers spend $250,000 on their mobile adgram.

so that is-- that's one example in the documents where they really talked about ity. direc >> schifrin: you said the privacy didn't come up in these documents. lieve that some of th documents show that facebook was motivated less bday usersta or protecting that user data and more about maxizing profit? >> yeah treally seems to be that wah at the time, representation to the public is these are t abusive apat are taking too much data. but let's step back fair second. facebook's permissions at the time, until 201 were so oose, that, as you heard mark zuckerberg'slip, if i signed into an app, i could actually be giving permission for the deloper to access your profile and all of my friends' profiles, even if you guys er signed into the app. so they're saying these developerdeveloper abused our pc in fact the pos were incredibly loose, and the developers went rampant with them. they built businesses offhem.

what you see here and how this data trove adds to the story, is you see how there were really deep, competitive reasons and r businesons yes they were pulling back data. and those didn't appear to have to do very much with privacy. >> schifrin: facebook has responded to these documents, of course. let me read the statement: elttom line: what's the difference betweenng the data and what they did? >> i think you've got to ask them, and they're not many answers beyond their own statements, you know. and i've been trying i think since i was up this tmorning a 4:00 a.m. so, yeah, i think they're going to have a l of explaining to do. and another question around that is whether any of this violates 2011 settlement that they have with the federal government, with the f.t.c., over whether whether they gave-- whether they were prohibited from giving

developers access to data users nshadn't coted to. and yet you have all these appse being whitelthat got data that apparently bypassessed people's permissions. that's going to raise a big question as well. and i think another interesting point that y see the documents is, for example, the video streaming app vine. this was i an that exploded on the scene. it was like the birth of liveg video streamom your phone. and facebook managers have a conversation where they ask zuckerberg, "hey, do you think now that vine is getting big on thscene, we should cut o their data?" and zuckerberg writes, "yup, absolutely." it was very clear that there were lots of motivations about how they were bro werg data that really has been such a big story sinlyce cambridge aca. >> schifrin: elizabeth dwoskin, silicon valley correspondent for the "washington post," thank you very much. >> thanks for having me.

>> woodruff: one of the big b questions thatng debated about the future of work is the extent to which robots,ci arti intelligence and automation may further eliminate, add or change our jobs. we're going to spend the next couple of nights of our series exploring that idea. tonight, miles o'brien looksma into whether wns may findtt a partnership with the bot next to us. it's the focus of onr weekly noorhe "leading edge" of science and techgy. >> reporter: robots on are on the march, rising, nalling. and if you watch t youtube channel for robot innovator boston dynamics, you might conclude they are out to replace us, or eveworse. m but at.i.t., roboticist julie shah and her team are desing robots with enough artificial

intelligence to collaborate with humans. cobots. >> if we're just going to design them to replace, we're living in a very limited sphere of what this technology can do and we can really open up the possibility by designing theas collaborators. >> reporter: so, we do more together? >> we can do more together. >> reporter: that's a relief. robots that march with us, on our side, right? but first, do no harm. please! so shah is making it safe for workers to get closer to the big, strong, fast but not so smart robots that are already used on assembly lines all over the world. >> we now have a new species really of inherently safe robots that can work right alongside eypeople. an bump into you and not permanently harm you in any way. e at's a game changer. >> reporter: with ght sensors and tracking software,s the robot slow stops when a huthn is in harm's way, and artificial intelligence, it

learns more efficient ways to avoid causg injury. collaboration? not really. thin is more like coexistenc close proximity. and on ftory floors, more and more robots are emerging from behind protective ba. >> if you look at a real cutting-edge warehse these days, you see this fascinating dance between people and rots. >> reporter: andrew mcafee is a principal research scientist at m.i.t. hetudies how digital technologies are changing business, the economy, and society. >> robots bring the shelves up p to tson and rotate it so that the right item is right in front of the person. and the person's job is to reach in and with their extrely dexterous hands, grab two of those things out and put them in a bin that's going to go off and get shipped off to me somewhere down the road. the robots are not yet capable of doing that reaching, grab to and put it away as accurately and as quickly as a human being can.

>> reporter: julie shah and her team aim to take this to a new level, devising machines that are flexible, smart assistants - able to adapt, even anticipatewh 's next, while their human co-workers do what they do best; thinking intuitively, creatively, innovating efficiencies. >> in almost every setting, where people are doing much of the work, there is little pieces of the work that can very easily be done by robots today. and the problem is not in enabling the robot to do those little pieces of work but enabling the rob to integrate and work effectively with the person so that they can accomplish the task together. >> reporter: a world filled with art helpful robots has long been a science fiction dream. >> welcome to altair iv gentleman, i am to transport you to the residence. >> reporter: but the real world is still far from the hope and the hype. big ideas for revolutionizing

the way we w intelligence and robots are just that: big ideas. but julie shah is undeterred, taking her approach into a workplace where things are less scheduled and predictable, to say the least. >> i would like to offer a recommendation. >> reporter: the labor and delivery floor at a hospital,wh e the nursing supervisors make an air traffic controller's job look easy. shah's robot is programmed with enough artificial intelligence to help nurses decide how to assign rooms and personnel. >> if we can offload even just e simple decisions and free up the cognitive capacity of these nurses that handle the most canicult situations, significantly improve safety in hospitals. s>> reporter: at massachu oyneral hospital they are seeing if they can emplrtificial intelligence in the operating room in real time for surgeons, like ozanan meireles. here is in the midst of a

laparoscopic liver gastrecthmy, staplingstomach of a morbidly obese patient. in the next room, sits his colleague, surgeon daniel hashimoto. they are part of a team deng software smart enough to offer advice to a surgeon during a complex operation. h ave shown the software hundreds, and soon thousands, of videos of the same procedure - so the machine learns the sequence and patterns of success. hais artificial intelligence is compared to what iening live in the o.r. >> what's it loo, ng at is, okis frame followed another, what's the probability that this frame is supposed to follow that? so, the red here marks areas where the computer has decided that that particular frame that it's looking at with sort of high confidence belongs to a certain step. >> reporter: o important steps is the placement of the staples relative to a notch in the stomach called the

incisura angularis. if the staples are too close,en the pawill have trouble swallowing. >> let's say if a novice surgeon of a surgeon, a community area, that is the only surgeon available and start this type of procedure gets too close to it, artificial intelligence through computer vision could actually give some like intuition to that surgeon and say, "you might be better off, go two or three centimeters away where you are"" >> reporter: hashimoto envisions a day when surgeons can instantly draw on the latest and best advice from everywhere; a collective surgical consciousness if you will- making decisions lind to patient outcomes years later. it will take some time before anything like this is deployed. among the thorny issues, it isea often unto computer programmers just how machine learning software aches its conclusions. it's a black box. >> you really need a human being whether it's a physician, whether it's a programmer,

whether it's a lawyer, to look at the output and say "is this a valid rt of recommendation that we're following?" >> reporter: much as we love our machines, humans le to have humans in the loop, especially when our lives are on the line. >> and in general, when something bad happens to a human being, they kind of want a human being to blame, to be responsible for that. it's just our wiring. >> reporter: machines and humana be good co-workers for now, lyt as the robots grow increasimarter and more flexible, there may come a day when they don't need a human partner at all. don't believe me? just watch. for the pbs newshourmiles o'brien in boston. >> woodruff: a lot more rhythm than many of us hav and that's the newshour for tonight. i'm judy woodruff. join us online and again here tomorrow evening.
