over the years we've reported on the more than half a million US servicemen and women who served in Iraq and Afghanistan and are suffering from post-traumatic stress disorder I couldn't even make sense of it but tonight you'll hear PTSD can be contagious the worst of it was in seventh grade I kind of decided that my family would be better off without me here Nvidia has had a blistering ride to the top of the stock market bill look at this how does nvidia's technology make artificial intelligence possible who are you I am fana a representation of Mother Nature it does quadrillions of calculations a second it's just insane numbers and medical researchers and high-tech companies tell us this technology will affect our lives in ways we Can Only Imagine This is Wild yeah it's an incredible feat honestly Pearl Harbor's Red Hill Bulk fuel storage facility 7 miles of tunnels cut through volcanic rock built to hold 250 million gallons of fuel so this is one of the tanks oh my gosh and to give you kind of a reference point the Statue of Liberty not the base but the statue itself can fit in here with enough room tonight you'll hear what happened at this one secret site and how it's affected thousands of military families I'm Leslie stall I'm Bill Whitaker I'm Anderson Cooper I'm Sharon alony I'm John wortheim I'm Cecilia Vega I'm Scott pelly those stories and more tonight on 60 Minutes 2 million Americans served in Afghanistan and Iraq and at least 600,000 have been diagnosed with post-traumatic stress disorder for the most part the US is doing better recognizing and treating these Wounded Warriors but less well known are millions more who are in need but remain hidden they are the children living with injured veterans in a profound sense PTSD can be contagious many children have become caregivers confronting depression and fear and you will hear tonight that the stress can be so great it can lead to attempts of suicide you're about to meet two courageous families who spoke to us so that others can know that help is on the way for America's children of war in 2011 Chuck rotenberry was a marine on patrol in Afghanistan when an improvised landmine detonated a few feet away which sent me down the hill 20 30 ft knocked me out um caused catastrophic injuries to the Marine behind me uh and the Marine behind him it was rotenberry second combat tour after Iraq what happened to the Marine behind you who had stepped on the IED he lost both his legs above the knee you and the medic put the touret on him yes sir you saved his life I helped out yeah when rotenberry came home from his 7-month deployment his wife Liz was pregnant with their fourth child Chuck was suffering with a brain injury from a concussion and PTSD Chuck was struggling to just be in the house because he was stealing with so many emotions mentally and physically um he was hiding in you know back rooms and I'd find him crying and he didn't understand why he was crying I didn't know whether I was coming or going Chuck kept a video diary as he dealt with self-isolation anxiety depression and denial one second I'm up super high and the next I'm not Chuck who was that man who came home in my head it was me but I was very far from it I think at age seven his son Christopher pitched in over the years he tried to Shield his dad from triggers that set him off and shield his sisters from the emotional trauma I just worried about a lot of different things things that kids iess at that age where should not be worried about um and it it kind of evolved into um kind of like a helplessness he was becoming almost like my husband there were times where he wouldn't be able to go to school because he was so stressed internally from everything happening and I don't think he knew how to process it and understand it I knew Christopher was was starting to struggle with the weight of it all the weight grew as Chris turned 12 the worst of it was in seventh grade I think i' kind of decided that you know my family would be better off without me here um I remember looking back on those days it was just chaos all the time and um I uh I remember taking my um one of the one of the dogs leashes upstairs and tied one into the bunk bed that we had my little brother's bunk bed and I tried you know hanging myself and um um it it was working and uh my mom walked in on me kind of and I think I was kind of on about to pass out I was kind of um you know losing Consciousness walking in and seeing what was happening to him and what he was really struggling with I knew everything else had to stop everything just had to stop and my focus had to be Christopher Liz became the Warrior fighting for her family Christopher went to intensive therapy then he and his sister enrolled in a clinic for military children confronting PTSD it's hard as a military family to own that when you're built with such pride and strength and you're seen as resilient as the word is in our community but it's okay to not be resilient and it's okay it's okay to ask for help therapy saved your family it did the guy stops and he like little was known about families like the the roten berries until the wife of a wounded warrior spent 10 months at Walter Reed National military Medical Center Elizabeth Dole former Senator and transportation secretary heard these families while caring for the late Senator Bob Dole and I met all of these young spouses mothers dads who were caring for their Wounded Warriors I don't think America is aware of what's Happening most Americans have no idea what's happening in these military families less than 1% are serving in the military today less than 1% are protecting our freedom and our security and so important for us to raise awareness of their challenges and their needs and provide them with the support Dole created a foundation that commissions studies of military caregivers the studies discovered that more than 1 million are caring for those in inured during the war since 911 nearly half said they were overwhelmed you know they felt guilty really that they were they were leaning on their children so much needing their support and that this was causing problems for the children there are 2.3 million military children living in the homes of Wounded Warriors that's how one of them is Elizabeth Cornelius and I just need to make sure everybody's okay cuz if my mom is isn't okay everything's going to just fall Elizabeth has helped her mom Ariel as long as she can remember even before she was born her dad brought terrifying memories home from a combat tour in Iraq Ariel told us his first episode came with a pizza delivery the delivery man came up to the door and knocked on the door and um you know my husband didn't expect it and he had the you know an immediate flashback in threw me to the floor and was yelling get down get down get down get down um even with that he deployed to Iraq again in 2007 and to Afghanistan in 2011 Ariel is a school teacher her husband is completely disabled by PTSD he can't work and wasn't up to speaking with us I have a video 16-year-old Elizabeth has become something of a co-parent to a brother and sister at home in Mont shielding them she told us from episodes and arguments I just try to Shield them as much as I can as my mom did for me and she did it for a very long time a lot of it falls on on myself and then she goes out and helps pick up the pieces that I can't her husband's worst crisis came on the anniversary of an attack that killed several of his fellow Marines um oh gosh um he was extremely suicidal because of all the memories that came back um he was barely hanging on and it's just that regret it's the um this the flow of memories that come in extremely suicidal but Ariel found beds for impatient Mental Health Care can be scarce you know Helena is an hour and a half to two hours away Casper Wyoming is eight plus hours away um and they didn't have a bed we then looked at Idaho they didn't have a bed we looked at Oregon they didn't have a bed we still ended up having to waake 3 weeks before he could get the support he needed in pet Sound Washington and you know that's 10 hours away 3 weeks during this time you felt like he could commit suicide at any point in time and we couldn't get help chasing care in a crisis and navigating government health insurance raised stress for everyone it's rough on her cuz she's been on the phone for hours and hours reading pamphlets trying to find us help in 2018 Elizabeth Dole watched president Trump sign a law that expanded VA benefits for caregivers of the severely disabled it offers a stipend access to health insurance and counseling the Dole foundation's studies found that at least 100 other organizations are providing support which now include the Dole Foundation itself Steve Schwab is the CEO how does the foundation help these children one of the first things that we do is we offer emergency financial support to anybody who needs it second is peer support we're building a first ofit kind peer support model that will link these children with other children like them for the first time in their lives we offer on the ground respit care backup care in the home to provide a trained healthcare worker to come in and back up that Mom or Dad so that that family can take a break together one Dole Foundation partner called our military kids paid fees to help keep the Cornelius children in sports their mom Ariel says that even the little things help her husband he is an amazing man and I can't wait for him to get past um and I know he'll never get past the PTSD but for him to heal enough to enjoy life and to be able tojoy the family Dynamics and those just being around you have hope for that I sure do yeah today Liz rotenberry leads a dole Foundation initiative to train caregivers to be public advocates for example on Capitol Hill husband Chuck is recovering and works as a dog trainer for the Secret Service and Son Christopher recovered and has applied to follow his father into the military after all the things that Chris did to help the family during your troubles what would you like your son to know first of all everybody everybody that's in my life now I wouldn't be here without them I tell them I love them all the time and he replies but I never really say why watching him grow being aware of other people there's plenty of proud dad moments for me but I'm proud of you every day all the time you owe me nothing but to be happy more than just about anything these families told us they want the nation to Simply see and know the children living with Disabled Vets who are in a sense still fighting America's post 911 Wars only four companies in the world are worth more than $2 trillion Microsoft Apple alphabet parent company of Google and computer chip maker Nvidia the California based company saw its stock market value sore from 1 trillion to $2 trillion in just eight months this past year fueled by the insatiable demand for its Cutting Edge technique technology the hardware and software that make today's artificial intelligence possible we wondered how a company founded in 1993 to improve video game Graphics turned into a Titan of 21st century AI so we went to Silicon Valley to meet nvidia's 61-year-old co-founder and CEO Jensen hang who has no doubt AI is about to change everything what at nvidia's annual developers conference this past March the mood wasn't just upbeat it was downright giddy more than 11,000 enthusiasts software developers Tech Mogul and happy shareholders filed into San Jose's Pro Hockey Arena to kick off of 4-day AI extravaganza they came to see this man Jensen hang CEO of Nvidia welcome to GTC what was that like for you to walk out on that stage and see that you know Bill I'm an engineer not a performer when I walked out there and all of the people going crazy it took the breath out of me and so I was the scariest I've ever been I'm still scared you'd never know it clad in his signature cool black outfit Jensen shared the stage with Nvidia powered robots let me finish up real quick and shared his vision of an AI future a new Industrial Revolution it reminded us of the transformational moment when Apple Steve Jobs unveiled the iPhone Jensen hang unveiled nvidia's latest Graphics Processing Unit or GPU this is Blackwell designed in America but made in Taiwan like most advanced semiconductors Blackwell he says is the fastest chip ever Google is gearing up for Blackwell the whole industry is gearing up for blackw NVIDIA ushered in the AI Revolution with its game-changing GPU a single chip able to process a myriad of calculations all at once not sequentially like more standard chips the GPU is the engine of nvidia's AI computer enabling it to rapidly absorb a fire hose of information it does quadrillions of calculations a second it's just insane numbers is it doing things now that surprise you we're hoping that it does things that surprise us that's the whole point in some areas like drug Discovery designing better materials that are lighter stronger we need artificial intelligence to help us explore the universe in places that we could have never done ourselves let me show you here bill look at this Jensen took us around the GTC convention hall to show us what AI has made possible in just the past few years I'm making your drink now some Creations were dazzling this is a digital twin of the earth once it learns how to calculate weather it can calculate and predict weather 3,000 times faster than a supercomputer and a thousand times less energy but nvidia's AI Revolution extends far beyond this Hall blue metallic spaceship and let's generate something panar Sean demera is originally from Istanbul but co-founded cubric near Boston her AI application uses nvidia's gpus to instantly turn a simple text prompt into a virtual movie set for a fraction of the cost of today's backdrops this isn't something that's already planned no we're doing it in real time it's life is Hollywood knocking at your door and we're we're getting a lot of love nearby at generate biom medicines Dr Alex Snider head of research and development is using nvidia's technology to create protein-based drugs she was surprised at first to see they showed promise in the lab initially when I was told about the application of AI to drug development I sort of rolled my eyes and said yeah you know show me the data and then I looked at the data and it was very compelling Dr Snider's team asks its AI models to create new proteins to fight specific diseases like cancer and Asthma a new way to defeat the Corona virus is now in clinical trials you're now working with proteins that do not exist in nature that you're coming up with by way of AI yes we are actually generating what we call denovo completely new structures that have not existed before do you trust it as scientists we can't trust we have to test we're not putting Frankenstein into people we're taking what's known and we're really pushing the field we're pushing the biology to make drugs that look like regular drugs but function even better this is a technology that will only get better from here Brett Adcock is CEO of figure a Silicon Valley startup with funding from Nvidia look at his answer to labor shortages an Nvidia GPU driven prototype called Figure one I think what's been really extraordinary is the pace of progress we've made in 21 months from zero to this in to this yeah we were walking this robot in under a year since I Incorporated the company could you do this without nvidia's technology we think they're arguably the best in the world at this I don't know if this would be possible without them I'm here to assist with tasks as requested we were amazed that figure one is not just walking but see to reason hand me something healthy on it figure one was able to understand I wanted the orange not the packaged snack thank you it's not yet perfected yeah you're going to get it but the early results are so promising German automaker BMW plans to start testing the robot in its South Carolina Factory this year I think there's an opportunity to ship billions of robots in the coming decades onto the planet billions I would think that a lot of workers would look at that as this robot is taking my job I think over time Ai and Robotics will start doing more and more what humans can and better but what about the worker the workers work for companies and so companies when they become more productive earnings increase I've never seen one company that had earnings in increase and not hire more people there are some jobs that are going to become obsolete well let me offer it this way I believe that you still want human in the loop because we have good judgment because there are circumstances that the machines are not just not going to understand the futuristic Nvidia campus sits just down the road from its modest birthplace this Denny's in San Jose good morning where 31 years ago Nidia was just idea my goodness when he was 15 Jensen hang worked as a dishwasher at Denny's as a 30-year-old electrical engineer married with two children he and two friends Nvidia co-founders Chris malikowski and Curtis PR envisioned a whole new way of processing video game graphics and so we came here right here to this Denny's sat right back there and the three of us decided to start the company frankly I had no idea how to do and nor did they none of us knew how to do anything their big idea accelerate the processing power of computers with a new graphics chip their initial attempt flopped and nearly bankrupted the company in 1996 and the genius of the engineers and Christen Curtis um we pivoted to the right way of doing things and created their groundbreaking GPU the chip took video games from this to this today completely changed computer Graphics saved the company uh launched us into into the stratosphere just eight years after Denny's Nvidia earned a spot in the s&p500 Jensen then set his sites on developing the software and hardware for a revolutionary GPU driven superc Compu which would take the company far beyond video games to walk Street it was a risky bet to early developers of AI it was a revelation was that luck or was that Vision that was a a luck founded by Vision we invented this capability and then one day the researchers that were uh creating deep learning discovered this architecture because this architecture turns out to have been perfect for them perfect for AI perfect for AI this is the first one we've ever shipped in 2016 Jensen delivered nvidia's AI supercomputer the first of its kind to Elon Musk then a board member of open AI which used it to create the building blocks of chat GPT how are you when AI took off hey guys so did Jensen hang's reputation can we get a picture yeah yeah he's now a Silicon Valley celebrity he told us the boy who immigrated from Taiwan at age n could could never have conceived of this it is the most extraordinary thing bill that a normal dishwasher bus boy could grow up to be this there's no magic it's just 61 years of hard work every single day I don't think there's anything more than that we met a humble Jensen at Denny's back at nvidia's headquarters in Santa Clara we saw he can be intense let me tell you what some of the people who you work with said about you demanding perfectionist not easy to work for all that sound right perfectly yeah it should be like that if you want to do extraordinary things it shouldn't be easy all right you guys keep up the good work Nvidia has never done better investors are bullish but last year more than 600 top AI scientists ethicists and others signed this statement urging caution warning of ai's risk to humanity when I talk to you and I hear you speak part of me goes she whiz and the other part of me goes oh my God what are we in for yeah yeah which one is it it's both it's both yeah you're feeling all the right feelings I feel both you feel both sure sure Humanity will have the choice to see themselves inferior to machines or Superior to machines Pinar Sean demera is an AI Optimist though she named her company cubric an homage to Stanley kubri the director of 2001 A Space Odyssey hello hell do you read me in that film Hal the AI computer goes Rogue open the pod bay doors hell I'm sorry Dave I'm afraid I can't do that I think that's what worries people about AI that we will lose control of it just because a machine can do faster calculations comparisons and analytical solution creation that doesn't make you smarter than you it simply computat faster in my world in my belief smarts have to do with your capacity to love create expand transcend these are qualities that no machine can ever bear that are reserved to Only Humans there is something going on Jensen hang sees an AI future of progress and prosperity not one with machines as our masters we can only hope he's right thank you all for coming thank you the US military takes pride in protecting its own that's why military families we met in Hawaii told us they feel so betrayed 2 years ago there was a fuel spill close to the drinking water system at the Pearl Harbor base in Hawaii Navy leadership assured thousands of military families that the tap water was safe but nearly two weeks after the spill parents learned the truth the water they drank or used to bathe their kids contained jet fuel tonight you'll hear from some of the families who say the jet fuel tainted water made them sick but first we'll go to where the water crisis at Pearl Harbor began from the air the historic Naval Base is easy to spot 8 mil from Honolulu sparkling Blue Waters host battle gray ships and memorials to those killed by Japan's surprise attack in 1941 what you can't see is the one secret storage site that provided fuel for the Pacific Fleet and its planes for 80 years it doesn't look like much from the outside wait till you get inside vice admiral John Wade led us through the Red Hill Bulk fuel storage facility 7 miles of tunnels cut through volcanic rock built to hold 250 million gallons of fuel so this is one of the tanks oh my gosh that black hole is a steel lined fuel tank so deep it's hard to see the bottom 20 stories below to just show you how enormous this is this tank holds 12.5 million gallons and it give you kind of a reference point the Statue of Liberty not the base but the statue itself can fit in here with enough room and this is just one of the 20 tanks hidden here this is the Arizona rising in death Agony when the Japanese bombed Pearl Harbor construction was already underway to protect the Navy's fuel Reserve from an aerial attack the decision was made to embark on a herculine task to build a bulk Storage Fuel facility inside a mountain in secrecy and how long did that take to do it was a little less than 3 years at its peak there are about 4,000 men working here watch your head we're going to go this way but this Testament to American resolve became a Monumental liability after this that's jet fuel sprayed from a cracked pipe the video was recorded by a worker inside Red Hill on November 20th of 2021 the fuel 20,000 gallons of it was trapped in a plastic pipe the weight caused the pipe to Sag this trolley hit it and jet fuel spewed for 21 hours close to the well that supplied drinking water for 93,000 people on and around the base at Pearl Harbor according to na investigators the workers who responded didn't have the right tools to contain the spill they also assumed there was no danger to the drinking water they were wrong at least 5,000 gallons of jet fuel drained into the tunnel floor and into the Navy water system the next day the Navy issued a press release about the incident and told the 8,400 families living in military housing the water remained safe to drink even though the Navy had not tested the water yet a week later residents began to notice a problem when did you get the sense that there was something wrong with the water my husband came into the kitchen and washed his hands and said gosh the water smells like I just did an oil change like the water smells weird Britney Trager lived on base about 2 and 1 half miles from Red Hill with her daughter and husband who is a Navy chief petty officer triager says she began to feel sick a week after the spill a week I had a cough my tonsils were very swollen I remember a very distinct moment where I was walking to the car and I had vertigo so bad that I had to hold on to the car the smell was that overwhelming mhm in an email to Residents 9ine days after The Spill the commanding officer of the base reassured residents there are no immediate indications that the water is not safe my staff and I are drinking the water did you stop using water did you stop taking baths so I did my daughter did just because you had a bad feeling not cuz anybody told you to correct they gave us an email address that we could send an email to if we wanted to have our water tested so I emailed those people who then emailed me a phone number that I should call and I called that phone number for days and it was just busy they were overwhelmed and inundated with reports 10 days after the spill there were more than 200 reports ports from six neighborhoods across the base of strong fuel odor coming from kitchen and bathroom faucets but the Navy said its initial test did not detect fuel it defied logic you know even though there was a leak and even though our water smelt like jet fuel and even though there was sheen on it they continued to say the tests are coming back negative after 12 days and four statements assuring residents the water was not contaminated with fuel the Navy reverse course on December 2nd 2021 it announced more comprehensive tests conducted by the Navy had detected jet fuel in the water 3 weeks after the spill test from Hawaii's Department of Health revealed jet fuel levels 350 times higher than what the state considers safe Michelle deetz lives on base with her husband a Navy chief petty officer and their two children that feels not something that you would even think could happen to be in your water how were people reacting to the news I was so sick to my stomach from that news that I actually threw up when I hurt because why because my kids have just been poisoned within a month the Navy set up medical tents for residents some complained of stomach problems severe fatigue and coughing the military moved more than 4,000 families to hotels small studies of military personnel suggest jet fuel exposure can lead to neurological and breathing problems but the long-term impact of ingesting jet fuel is unknown because it's so unlikely to ever happen relle Deets told us days after the spill her daughter's tonsils became inflamed and her son started suffering from chronic headaches I can hear people saying tonsils headaches kids get that stuff how do you know it's related um because they never had it before November of 2021 it wasn't an issue it's unclear how many got sick but of 2,000 people who responded to a survey by the Centers for Disease Control and prevention more than 850 sought Medical Care the water system was flushed over 3 months and bottled water brought in Britney Trager said her 4-year-old now suffers respiratory problems which require hour-long treatments at least two times a day that includes a nebulizer and this vibrating vest to clear her lungs tell me about your daughter's Health 13 days after the contamination after our water smelt like jet fuel my daughter woke up in the hotel with a cough and it pretty much never went away 3 months p passed before Pearl Harbor's drinking water was deemed safe again the Navy's own investigation into the spill described quote cascading failures and revealed poor training supervision and ineffective leadership at Red Hill that fell unacceptably short of Navy standards for the last 10 years Hawaiians have raised concerns about the threat from smaller leaks at Red Hill the primary water supply for the city of Honolulu is 100 ft below the Navy complex in March of 2022 the Secretary of Defense ordered Red Hill permanently closed vice admiral John Wade was brought in to get the 104 million gallons of fuel out of the tanks and move it safely to sites around the Pacific we've got to defuel that's the imminent threat there's ongoing and will be continued long-term environmental remediation to restore the aquifer the land and surrounding area and then there's also a medical component for those that have been impacted you view now this thing that was a Lifeline for the fleet mhm is a threat that's right that's right in 6 months Wade's team in Hawaii successfully removed almost all of the fuel but it took 2 years before the Navy issued disciplinary letters to 14 officers involved in the spill response including five Admirals was anyone fired because of this at the time that the accountability came through uh we had officers that had already retired and so uh they had already separated from service Meredith Berger is an assistant Secretary of the Navy we met her at the Pentagon in November she told us the Navy has been accountable we're talking about 20,000 gallons of fuel leak 990,000 people had their water contaminated it looks like people retired or were reassigned and no one was fired how is that accountability it's accountability within the system that we have established and we have heard that this was too long um and that maybe it didn't go far enough 2,000 military families agree the Navy didn't go far enough and are suing the government the tagers and deas have joined the lawsuit alleging they were harmed by negligence at Red Hill are you angry that it happened or are you angry at what happened after it's a little bit of anger but it's also this feeling of betrayal what do you mean betrayal so my husband has been in for almost 18 years we have moved our family cross country cross oceans we gave so much of our life to the Navy for them to ignore warnings and then we were directly and blatantly lied to about it Navy leadership has apologized for the spill but has not said that the contaminated water is the cause of the ongoing illnesses the Navy did set up a clinic on base to collect data and treat anyone who believes they have health issues related to the tainted water what happens in 5 or 10 or 15 years will those Services still be available to these families so that's that is part of why um we are making sure that we're collecting that information to inform future actions and what the requirements are for those types of uh needs and care that doesn't sound like a guarantee of care in the future and I want to be careful because I don't do the health care part of things and so I I don't want to speak outside of um of of where I have any Authority or decision so we followed up with the defense department which told us it's reviewing the question of long-term health care for military families including more than 3,100 children two years after the spill some residents have reported water with a smell or Sheen the Navy is conducting daily tests at Pearl Harbor and says it is confident there is no fuel in the tap water Michelle DEET is still using bottled water the lawsuit she joined with Britney Trager and the other military families is scheduled to go to trial tomorrow What is the remedy that you want in our family it's restoring my in our nation that's a big thing to say there's a body of government that failed they contaminated our water they lied to us they did not protect us and they did not intervene and accountability looks like a lifelong care plan for me my family and the people affected and that will restore my faith in my nation does Red Hills still pose a threat to Honolulu this facility was a disaster waiting to happen at 60 minutes overtime.com
