♪ welcome to all of you watching us here in the united states, canada and all around the world.

i'm kim brunhuber ahead on "cnn newsroom." >> it was a very difficult decision on my part. and by the way, i discussed this with our allies, i discussed this with our friends up on the hill, and we're in a situation where ukraine continues to be brutally attacked. >> president biden explains why he's sending cluster munitions to ukraine 500 days after russia invaded the country. plus, u.s. treasure y secretary is in china covering everything from trade to the environment. and the global summit on ai for good. >> live from cnn center, this is "cnn newsroom" with kim brunhuber. >> the biden administration has confirmed that highly controversial cluster munitions will be included in the latest u.s. military package to ukraine. these weapons shower small but lethal bomblets over a wide area, but many don't explode and

remain deadly for years. they're banned by more than 100 countries but not the u.s., ukraine or russia. president biden had long resisted ukraine's request for the munitions but said he reconsidered in light of recent changes on the battlefield. here's what he told cnn's fareed zakaria in an exclusive interview. >> we're in a situation where ukraine continues to be brutally attacked across the board by these cluster munitions that have dud rates that are very very high, that are a danger to civilians, number one. number two, the ukrainians are running out of ammunition. the ammunition, they called them 155 millimeter weapons, this is a war relating to munitions. and they're running out of that ammunition. >> now, before biden would grant the request for the cluster bombs, ukraine first had to agree to strict rules of how

these weapons would be used. cnn's jeremy diamond has more from the white house. >> reporter: president biden's decision to provide cluster munitions is clearly one he made reluctantly. he explained it was a difficult decision and one that took a lot of convincing for him to get to place where he was willing to approve this. there was months of debate, and among the national security team who recommended unanimously to the president that he take this step. it is a step in the words of the national security adviser jake sullivan, intended to provide a bridge of supplies to ukraine. they are clearly running low on ammunition, and this provision of cluster munitions is intended to get them the ammo that they need while domestic manufacturing of conventional artillery shells is ramped up here in the united states. but this is certainly a controversial decision. more than 100 countries have banned the use of cluster munitions, including france and germany, key nato allies and it

also required that president biden bypass a u.s. law that prop prohibits the transfer of munitions to other countries. the president determined it was in the vital national security interest of the u.s. to do that. u.s. officials have also previously said that these munitions have no place on the battlefield and i asked the national security adviser jake sullivan on friday how he scarce the comments with the decision. >> i'm not making an argument that says they do it so we'll do it. the argument i'm making is that russia has already spread tens of millions of these bomblets across ukrainian territory. we have to ask yourselves is ukrai ukraine's use of cluster munitions on that same land actually that much of an addition of civilian harm given that the area is going to have to be de-mined. when we look at what ukraine is doing with the weapons as opposed to what russia is doing with the weapons, we see a substantial difference.

it doesn't make it an easy decision. it's a difficult decision. >> reporter: and sullivan repeatedly distinguished how russia has used these cluster munitions and how ukraine would use the ukrainian provided cluster munitions. russia has used the munitions against civil areas. ukraine has provided written assurances to the united states that it will seek to minimize impact on civilian areas, including not targeting urban areas, and he also argued that ukraine is ultimate lily motiva to minimum risk to civilians. this is their land they are defending and beyond that he noted that the cluster munitions the u.s. is going to be providing to ukraine, that they have a lower dud rate, meaning that a smaller percentage of them ultimately do not explode. 2.4% for the u.s. provided munitions to ukraine, compared to 30 to 40% on the cluster munitions that russia is using.

jeremy diamond, cnn, the white house. >> the revised u.s. policy was quickly denounced at u.n. listen to this. >> the secretary general supports the convention on cluster munitions which as you know was adopted 15 years ago, and he wants countries to abide by the terms of that convention. and so as a result of course he does not want there to be a continued use of cluster munitions on the battlefield. >> and there's also been the swift backlash from some members of the president's own party. two democratic senators wrote in the "washington post," quote, providing cluster munitionis to kyiv would erode the moral advantage held by ukraine since the start of the war. on the 500th day of the war, ukraine's president visited a site that's become symbolic of the country's resolve. he toured snake island on the black sea where a group of

ukrainian soldiers delivered a defiant response to a threat from a russian warship. president zelenskyy honored the troops saying quote, today, we are here on snake island which will never be conquered by the occupier, nor will the entire ukraine because we are the nation of the free, even though it is a small piece of land in the middle of our black sea, it is a great proof that ukraine will regain every part of its territory. earlier president zelenskyy visited president erdogan to shore up support from nato countries. here he is. >> translator: ukraine deserves nato membership. i would like to reemphasize a point that i have always defended persistently, a fair piece creates no losers, despite the differences between the parties it's our most sincere desire to return to the peace efforts. >> turkey is working to extend

the deal to russia export grain through the black sea. the russian leader would visit turkey next month. >> president biden said he doesn't believe ukraine should become a member of nato just yet. here's what he told cnn's fareed zakaria. >> i don't think it's ready for membership in nato, but here's the deal. i spent, as you know, a great deal of time trying to hold nato together. i believe putin has had an overwhelming object ive since h launched troops into ukraine. he was confident he could break nato. holding nato together is really critical. i don't think there is unanimity in nato about whether or not to bring ukraine into the nato family now at this moment in the middle of a war. >> it comes days after president zelenskyy made a direct appeal to president biden saying in an

interview with erin burnett, ukraine needs to be part of nato now. nathan, let's start there with zelenskyy's trip to turkey. did zelenskyy get what he came for? >> kim, first, he got a very clear message of support, i'd say from turkish president erdogan. with erdogan not only reiterating the idea that, you know, ukraine needs to be in nato, but also reminding people that crimea in his view, you know, needs to be returned to ukraine. this is the black sea peninsula that was occupied by russia back in 2014. well before last year's full scale invasion of ukraine. and equally important, zelenskyy, by meeting with erdogan, is also meeting with a key interlocketer of russia president vladimir putin. erdogan has for years maintained

quite an open channel of communication with putin. he's been key in this deal to -- in brokering this deal to open ukrainian ports to the export of grain, as well as things such as prisoner exchanges. erdogan pointed out something that i think is an important point for the ukrainian side, the rights of the crimean minority, a turkish ethnic group native to the crimea peninsula, again, which has been under russian occupation since 2014, so i think he certainly did, zelenskyy, come away, i think, with a broad message of support. especially in, you know, amid this rolling offensive, kim. >> i want to get back to our top stories and the u.s. decision to cluster munitions to ukraine, a controversial one. i mean, we heard the white house

making its defense of its thinking there. what does it say that ukraine has to resort to asking for these bombs that could well injured or kill their own civilians for years to come? >> kim, that's where, you know, the main question comes in about reducing civilian harm, and the big issue all along with cluster knew in a munit munitions, and the reason countries are signatory to the ban is what you call the dud right, and we're seeing technical descriptions of what the appropriate dud rate should be about the munitions sent to ukraine. a certain percentage of bomblets scattered over a wide area, they don't go off. essentially creating kind of a land mine hazard for civilians and in the area where they have been dropped. now, the ukrainians have come back and said, you know, they've offered guarantees in thanking the u.s. saying these would be delivered. ukraine's defense minister said

they would abide strictly with international humanitarian law on the usage of these weapons. in other words r, you know, avoiding built up civilian areas. again, though, i think that it is pointing to the larger problem that ukraine is going to have particularly in the east. but also throughout the country of massive amounts of unexploded ordinance. we're seeing especially in the donbas region, something that really resembling sort of the 21st century version of world war i trench warfare with just enormous amounts of orthem bein lobbed across the territory. >> finally, looking big picture here, 500 days into the war, i mean, surely when it started that's not a sentence many of us thought we would be saying. are we any closer to an end now or are we more likely eventually

noting the thousand day mark? >> no one really can say, but it is important, though, as we observe this grim milestone to be reminded of the civilian cost of this war. ukraine's prosecutor general put out a statement today saying that nearly 500 children have been documented, have been killed in these 500 days of the full scale invasion of russia. i mean, we recently saw the russian strikes on a pizzeria in kramatorsk in the east. cruise missile strike on the western city of lviv, claiming civilian lives after hitting a residential building. so while zelenskyy did have, you know, an important photo opportunity here, which was commemorating the defenders of snake island, you know, quite famously, the ukrainians came up with a postage stamp showing the ukrainian soldier defending the island giving the middle finger

to a russian warship, and this is an important symbol of ukrainian defiance, and resilience that we've seen since the beginning of, you know, since following the full scale invasion of february of last year, so definitely the ukrainians today, this is not a joyful milestone. i mean, this is one that speaks to the immensely high cost of war, but things are unpredictable just as we've seen in russia with this, you know, apparent armed rebellion by the wagner mercenary group in russia. things can change very quickly in war, and war does unleash unexpected forces, kim. >> absolutely. an important and poignant reminder you say there, one child dead for every day of this tragic war. nathan hodge, thank you so much. on the front lines, ukrainian troops have reported,

quote, hot fighting against russia as their counter offensive goes on. enemy fighters have tried to breakthrough, but have so far failed, advancing more than one kilometer in 24 hours. they s ty are putting on so much press rusan forces are trapped in the city. in the south, ukraine says it's destroying russian equipment and weapons and the russian forces are suffering quote, significant losses in manpower. cnn's ben wedeman has more on the front line advances. >> reporter: as soon as one artillery round blasts toward bakhmut, the crew rushes to prepare for another. ukrainian officials report gains around the town that since last year has been the epicenter of the war. gun commander artem has been in the area for months. the task of taking down coordinates and barking orders, now routine. he says he's now half deaf from the blasts.

yet he has sense to change. it feels like they're often running away, he says, referring to the russians, and then the order to fire. there's barely a let up in the distant thud of shelling. the russian says this gunner called sign aries are falling back. we know because they hit us much less. one or two months ago, there was a lot of incoming. it was scary to be here. now it's different. on another flank, the big guns are out. this is a bodana, a ukrainian made 155 millimeter, self-propel self-propelled howitzer. ukraine claims the russians have put 150,000 troops. the russians have fortified their positions and stand strong

demander dmytro tells me, but i think that's temporary. russian soldiers captured in the battle told us the shelling on their positions was relentless. that was a high explosive anti personnel munition fired at the direction of russian troops outside of bakhmut. >> as soon as they fire, they prepare to fire again. ben wedeman, cnn, near bakhmut. >> china is holding key meetings as both countries prepare to repair their fractured relations. u.s. treasury secretary is in beijing. she met with the premiere hoping they can meet halfway and put their relations back on track. yellen held a round table meeting with climate finance leaders and a lunch meeting with female economists, and wrapped

up a meeting with vice premiere. yellen's latest meeting, take us through what happened? >> reporter: she has been meeting with vice premiere at the state guest house. the two will also have dinner this evening. the vice premiere said that he and yellen had met back in bali in november of last year at the g20 summit and said that the chinese leader xi jinping believes the u.s. and china relationship should be stable. now, in yellen's opening remarks, she said the complicated global economic outlook means there's a pressing need for the two lgest economies to closely communicate. she went on to say, and let me read you the quote, i believe the united states and china should seek a relationship of healthy economic competition that is not winner take all but that with a fair set of rules would benefit both countries over time. where we have concerns about specific economic practices, we

should and will communicate them directly. now, yellen's trip has been very productive, kim. that's according to the u.s. ambassador to china, nick burns. he said it's really helping, you know, reset the relationship. this morning, as you mentioned, yellen took part in a round table with climate finance leaders where she said the threat of climate change was a top global challenge and that both countries, as the largest emitters of greenhouse gases must work together. yellen's most important meeting was yesterday with chinese premiere. he described yellen as a builder, working to improve economic ties between the u.s. and china. beijing sees her as a voice of reason within the biden administration. she's argued against tariffs and warned decoupling would be disastrous. chinese officials certainly appreciate that sentiment. but yellen also met with

representatives of the u.s. business community where we got an insight, perhaps, into the challenges that she's facing on this visit. she expressed concern in recent months, also china's decision to control exports of critical minerals used in technologies like semiconductors. this is a tit for tat on further restrictions on technology trade from china, including potential limits on advanced tips and u.s. investments in china, citing national security. a very contentious issue for the u.s. and china, no doubt, has been discussed with the vice premiere. yellen's meetings wrap up this evening. tomorrow morning she'll hold a press conference before flying back to washington. >> and you mentioned that from the u.s. perspective, they're saying, you know, relations are improving. what's been the reaction so far in china? >> well, look, i mean, we got that quote from the chinese

premiere yesterday. who spoke about the rainbow when janet yellen's plane arrived in beijing. perhaps it's symbolic, there will be wind and rain, and hopefully also rainbows. i think what we are hearing from china is that they are open to, you know, improving ties, as we just heard from the vice premier, he believes that the u.s. and china should have a, you know, a stable relationship. so that is what this is all about. it comes off the back of u.s. secretary of state antony blinken's trip, you know, just over two weeks ago. janet yellen obviously has had a successful trip. i think it's safe to say, nicholas burns, the u.s. ambassador to china really, you know pointing that out this

morning. then we know that john kerry, he's also, you know, locked in plans to come to beijing perhaps, you know, next week. so certainly things are progressing, and hopefully this will, you know, be a real reset in the u.s./china relationship. >> thank you so much for that appreciate that. so much more to come here on cnn. former president donald trump campaigns in iowa and tries to spin multiple investigations to his advantage. and the shooter who killed two dozen people in a texas walmart receives his sentence in federal court. we'll have that and d more afte the break.

try killing bugs the worry-free way. not the other way. zevo traps use light to attract and trap flying insects with no odor and no mess. they work continuously, so you don't have to. zevo. people-friendly. bug-deadly.

on the campaign trail, former president donald trump has been trying to spin the multiple special counsel investigations to his advantage. he says the inquiries are making his poll numbers go up, but his republican challengers are hoping to use trump's legal trouble to their advantage. jeff zeleny is in iowa. >> if i weren't leading fin the polls by so much, they wouldn't be indicting me.

>> reporter: trying to use the indictments as a rally. >> i will never let them take away your freedom. >> reporter: the former president making clear he's consumed by the probe of his attempts to cling to power and overturn the results of the 2020 election. >> every time i get a subpoena, you know my polls go up, i get more and more subpoenas, report to a grand jury, he's killing biden. >> reporter: before his appearance in council bluff, said he would focus on a leading rival. florida governor ron desantis. >> he would be a total disaster, every iowan needs to know that ron desanctimonious despises iowa. >> reporter: trump returned to iowa as many republican rivals bluntly question his ability to win a general election, as they seek to gain attention in a

crowded field of candidates, some contenders are taking to the air waves. >> small town boy, self-made business leader. >> the radical left have chosen a culture of grievance over greatness. >> reporter: others are shaking hands, introducing themselves to one voter at a time. former have the mike pence implored republicans to turn the page to avoid losing in 2024. >> i believe that different times call for different leadership. >> reporter: more than six months before the presidential nominating contest begins in iowa. republicans are a party divided, between trump excitement and trump fatigue. starlin perdue who leads the republican party and is staying neutral in the primary is uncertain how that divide will be settled. >> there are people that are still very much pro trump, other ones that are exploring their options, so it will be interesting to see how it plays out. i think truly it will just be time will tell on how it will impact his election. >> reporter: with the iowa caucuses set to open the

presidential republican contest in early january, one thing is clear, trump's campaign and had his legal case have one argument behind him. the former president using this indictment and investigations as a weapon to rally support among republicans. the question is can any other candidate breakthrough and challenge him one on one? jeff zeleny, cnn, council bluffs iowa. rudy giuliani, one of trump's former attorneys has already had his law license suspended in new york. now his role in trying to overturn the 2020 election could get him disbarred in washington. cnn's sara murray has the latest. >> reporter: more troubles for former trump attorney rudy giuliani. an attorney disciplinary committee recommending giuliani be disbarred in washington, d.c. for his efforts on trump's behalf to overturn the 2020 election results. he claimed massive fraud but had no evidence of it, the committee wrote, by prosecuting that

destructive case, mr. giuliani, a sworn officer of the court forfeited his right to practice law. he should be disbarred. the three person panel was unanimous in their recommendation. he said he had reason to believe the claims were true and he was relying on what others working with the trump campaign had told him about the fraud allegations. this recommendation from the disciplinary committee is not the final word on disbarment. d.c.'s board on professional responsibility will need to consider the case against giuliani as will the d.c. court of appeals a. political adviser to giuliani called the report, quote, a great injustice adding the decision makers at the d.c. bar association are nothing more than an arm of the permanent regime in washington. sara murray, cnn, washington. just ahead, we take a closer look at the disturbing rise across the u.s. of a street drug called trank. it leaves users in a zombie like stupor and can eat away at their

limbs. stay with us.

welcome back to all of you watching us here in the united states, canada and all around the world. i'm kim brunhuber. this is cnn newsroom. on friday, the mass shooter who killed nearly two dozen people in a walmart in el paso, texas, was sentenced to 90 consecutive life terms. patrick crusius showed no emotion as his sentence was announced. he pleaded guilty as part of a plea deal that kept the death penalty off the table but still faces capital punishment in a state case. rosa flores has more. >> reporter: a federal judge has sentenced patrick crusius to 90 consecutive life sentences in

prison in relation to the 2019 el paso walmart shooting, which is considered one of the deadliest attacks on hispanics in modern u.s. history. during the allocution, which is when both parties are able to make statements, the defense said that the shooter takes responsibility but then went on to blame the shooter's mental illness. now, the prosecution rejected that saying that the judge in this case should really justice focus on the facts of the case, which in this case include that a shooter drove to the city of el paso, and went on a hate-filled rampage against hispanics and ended up killing and wounding dozens of people. now, this act, according to the victims that spoke in open court did shatter the sense of safety in this community but what it didn't do is it didn't shatter the sense of pride in this

mexican-american border town, where many of the individuals who live in this city are mexican americans. now, for the victims, it was very difficult for them to be in the same courtroom with the shooter, but many of them said it was important for them to be there. take a listen. >> i think it's about what's going on in america with all the white supremacists, all the hate. i just feel also that nothing's going to change. giving due diligence and due process to a mass shooter. >> this was really hard. a lot of it just hearing what the families had to say. i don't know how you can sit through that and not have a tear come out of your eye. >> reporter: as the hearing ended and the shooter was being walked out by u.s. marshals, dean ricard, the son of margie ricard, a victim in the el paso shooting yelled out, quote,

we'll be seeing you again coward. he's referring to the state case because the shooter is facing a capital murder charge in the state. now the death penalty is still on the table in that case. the shooter has pleaded not guilty. that trial has not been set yet. rosa flores, cnn, el paso. >> u.s. secret service is expected to wrap up its investigation in the coming days of a small quantity of cocaine found last weekend in the white house but identifying a suspect may be difficult given that many pass through that part of the west wing. on friday, national security adviser jake sullivan had this to say about the situation. >> we have rigorous drug testing policies at the white house. we have rigorous drug use policies at the white house. we take those extremely seriously, so we'll let the investigation unfold. if it involves someone from the white house, the appropriate

consequences will ensue. the drugs were discovered in a cub by near the ground floor entrance of the west wing, a place frequented by both staff and visitors. an elicit and highly dangerous drug called trank is spreading across the u.s. governors are wrestling with what to do about the flesh killing drug. we have to warn you that some of the images in this report may be disturbing. cnn's danny freeman is in philadelphia where a surge of trank can be seen on the streets. >> i've been using all my life. >> reporter: gyjimmy golden doesn't remember when trank started showing up in philadelphia's neighborhood. >> i call it the drug that bites hr. can't forget the impact it has left. >> a lot of people are losing limbs, the trank, it gets into your bloodstream and eats at your skin. >> reporter: in recent years, the animal tranquilizer known as

trank has found its way into a exploding opioid crisis, in part because of its low cost. illegal fentanyl is frequently cut with zylosin, but users don't always intentionally seek it out. the drug is not approved for human use. it calls open necrotic wounds and often leaves users motionless. >> reporter: what does it feel like when you're on trank? >> i don't know, because it passes you out. >> reporter: it passes you out, knocks you out immediately? >> here in philadelphia, it was found in dope samples in 2021, making a difficult problem even worse. >> it's not an opiate, people are having opiate withdrawals. >> meghan cohen used to be addicted to heroin. now sober, she leads a group of

volunteers for those suffering from addiction, for food, resources and wound care. >> if it's severe, sometimes we have to do surgery. most of the time folks need iv antibiotics or need to be admitted to the hospital. >> reporter: this problem is not isolated to the small section of philadelphia. >> it's easy to see this problem here because it's so concentrated so people are so drawn to kensington to talk about zylosene, the reality is everywhere. >> reporter: it contributed to 51 overdose deaths in a handful of counties near philly. by 2022, it contributed to nearly 650 overdose deaths across more than 35 counties. >> we're seeing it present all across this commonwealth. that's why we took action. >> reporter: josh shapiro's administration addressed

zylosene. >> it allowed the substance to be controlled. for law enforcement to have greater tools to stop the flow of it on to the streets and hopefully allow us to save lives. >> reporter: we have been speak to go advocate on the ground who have said fentanyl is illegal, heroin is illegal, and yet people are still dying from those drugs. >> i was the attorney general before becoming governor. and as attorney general i arrested 8,500 drug dealers across our commonwealth. that had an impact on the streets. i was the first one to say you can't arrest your way out of this crisis, you have to take a multidisciplinary approach. >> reporter: megan says wile the government is starting to catch up, it's still behind it comes to understanding and treating the impact of trank. >> these are human beings and they need help. there was no big warning saying it's going to come into your drug supply and this is the effect it's going to have. they were already using, and here we are, people are losing

limbs. a lot needs to change. we have to keep up with the times. >> reporter: do you have faith the government can stop trank from getting on the streets here? >> if they stop, it's going to be something behind it. it's not going to stop. >> danny freeman, cnn, philadelphia. as artificial intelligence moves forward, there are growing concerns about what the future could look like. the u.n. is hosting a two-day summit to talk about it with robots taking center stage. we'll have that coming up, stay with us. okayay... i'll work on that. the queen sleep number 360 c2 smart bed is now only $899.. plus, frfree home delivery when you add an adjustable base. shop now only at sleep number.

inundated with scary stories about how ai could pose a threat to humanity, but a u.n. summit this week in geneva aimed to prove the opposite. the ai forgood global summit brings together more than 3,000 leading tech executives, academics and international

organizations to explore the benefits of artificial intelligence. major themes of this year's summit include ways of using ai to enhance health care to fight climate change and bridge the digital divide between rich and poor communities. the attendees also discussed governance of ai and ensuring it's using responsibly. listen to what one of the robots had to say at the forum. >> i am a robot. i have a human like physical appearance, but i am not a human. i am very grateful for you giving me life and i'm proud to be your creation. >> with me now is one of the creators of that robot, nadia talman, a professor at the university of geneva. thank you so much for being with here with us. i imagine most watching this will react with a mixture of fascination and fear. if you were to make the case to folks who might be a little amp henciv apprehensive about this, how can your robot and others like it be

a force of good? >> the objective of making the robot is really to help people. as well as academics in the time i used to be in singapore from 2009 to 2021, we developed quite a lot of organisms to make the robot be able to communicate nicely with people, and after this, we published a lot of papers and have a lot of ph.d.s, but after this, we put nadine in a situation where we can prove that she is there for good. and one of the application was to bring her in an elderly home where people were slightly dement and we spent quite a lot of the time to prepare this visit with nadine and when she was there, she interacted with

patients, and she played bingo. she could talk to them whenever they like. she played her favorite songs. and when you ask what is good in that, it's in most of the cases in elderly homes, we don't have anybody to be taking so much time for you, so nadine was available 24 hours, and anybody could come to her whenever they have a problem, pleasure to discuss or listening and so on. >> seniors, you know, they're not always welcoming new technology, but as well, how do you overcome the so-called uncanny valley, which is as robots become more human like, they become more appealing until they get to that point where they're too human and then that response turns to revulsion? >> i think thanks to, for example, to chatgpt, the

language and robot answers is much more natural, and, you know what is fantastic really in this elderly home, the people, the residents knew from the beginning and also were aware that it was a robot. they never thought it is a person, so that mean it was great because they understood it is a tool that can help them with whom they can talk and make jokes, for example, but this uncanny value didn't happen. we made a user case study of the background of the social workers there and also from them, where they explain how they feel, and it was all positive. >> in my reporting from silicon valley on robotics, even as recently as a few years ago, the expert opinion was that even the smartest robots were actually

really dumb. they're great for repetitive tasks, not so great dealing with complex human behavior, but it sound like ai might be the game changer there? >> yes, because they are more clever. you know, for example, nadine was, with the permission of the residents and families, was able to discuss with them to remember facts and emotion. so it was like kind of natural languages, so if you present robot with more things, i would say, it's not the same. the more they have similarity with humans, the more they trust the help. and nadine, for example, was playing bingo, so that's not so many people who have time to play games. >> let me jump in with the flip side because i did want to ask you about this before we go. i mean, the controversy over

chat bot gpt, the bot that fell in love are the reporter. we covered that extensively, there were dangers people could form false attachments to the bots and the feedback they're getting from there. is that danger increased exponentially if they're chatting with a humanoid. >> it's not what i see. i didn't notice that. the problem is we need to not let people, the social robot is a human. so, for example, in our case, nadine will always answer i'm a robot. i'm here to help you. if we ask her what she eats, she will say i'm fed up with electricity, but if the people who create the social robot start to simulate a real human and say i have a dream, i fall in love, sure it could be

dangerous. so we need ethical rules of what the robot, what robots in general are able to say or are allowed to say, so there should be a governance in this. we cannot let robots going -- >> yeah, absolutely. well, listen, what we're seeing mow, this is clearly only the beginning but we appreciate this window into the future. nadia talman, thank you so much for speaking with us. >> thank you. all right. still ahead, this week, the planet saw its four hottest days on record, the latest evidence the earth is heating up much faster than expected and another wake-up call in the climate crisis. stay with us.
