the uk has registered a daily record of more than 78,000 cases of coronavirus, the highest since the pandemic began. the number exceeds by 10,000 the previous record injanuary. the uk's chief medical officer warned many more records would be broken over the next few weeks. president biden�*s announced the us federal government will cover the entire cost of 30 days of clear—up in the state of kentucky following friday's devastating tornadoes. mr biden described the destruction there as "almost beyond belief." at least 7a people died in kentucky and 1a others in other states. the influential black feminist known as bell hooks has died at the age of 69. the author, professor, poet and activist whose real name was gloria jean watkins wrote dozens of books. she died at her home in kentucky surrounded by family and friends.
now on bbc news, it's time for click. this week, what will it take to keep us all safe? will machines lead us into war? how do we stop killer robots from becoming a reality? and can the victims speak louder than the survivors? theme music plays has there ever been a time when we haven't been at war? battles have been raging down through the ages over lands, religion and resources.
and every so often a new technology comes along, which gives one side a massive advantage and changes the shape of war forever. throughout the history of warfare, there has been one common thread, and that it's been people who have made the decisions on who and how to fight. but now we're having to ask the question — what would happen if you took the human out of the loop? weapons, guided and driven by artificial intelligence, are no longer science fiction. and next week, the un will discuss whether the development and deployment of this kind of tech should be left unrestricted, should be regulated or outright banned. so far, the us and the uk have opposed binding agreements to regulate or ban the use
of so—called �*killer robots�*. james clayton reports from silicon valley on the dawning reality that al researchers say we need to start thinking about today. the nuclear bomb totally transformed warfare. there are those that now say that we're on the cusp of something similar. it is a fast track to — i think "dystopia" is the right word for it. the nation is still recovering from yesterday's incident which officials are saying is some kind of automated attack, which killed 11 us senators at the capitol building. autonomous weapons combine a confluence of different technologies — drones, facial recognition, artificial intelligence and big data to create a sort of super weapon that not only detects and destroys, but can make that decision itself, and can be owned not just by states,
but potentially by organisations, terrorist groups, anyone. this is the kind of dystopian reality that has been painted by critics — assassinations, private armies of bots, computers deciding whether humans live or die. these types of weapons that could easily be deployed and moved throughout different environments, like a swarm, the sort of embodiments of the robo—dog with the machine—gun, and how easy they can proliferate, how easy they can fall into the hands of not what we think of as traditional militaries. gunfire this isn't about prohibiting or banning ai usage in the military, or even in weapon systems. it's about drawing a red line on the specific use case of weapons, which are these smaller types of systems that target people. even the un secretary general is worried. the weaponisation of artificial intelligence is a serious danger. on december 13, a review
of conventional weapons is scheduled to be held at the un in geneva, where they'll be discussing killer robots. campaigners will be looking for an outright ban. but, already, that looks unlikely, with the us reportedly saying it would prefer a non—binding agreement. the discussion should be more about how we regulate it and how we kind of try and define it and approach it rather than trying to outright ban it, which is not going to happen. russia, china and the us are going to go after these technologies, so they are very keen to avoid being put at a competitive disadvantage against what is increasingly looking like the sort of great power, cold war—type competition over the next 30 to 50 years. but if countries can't ban killer robots, what will that mean for humanity? it is a fast track to — i think "dystopia" is the right word for it. it is a world in which we've
delegated and relegated the decision to take a human life to algorithms, right? but it's not quite as simple as that. 0thers argue that autonomous weapons are often mischaracterised. it's not being given the authority to kind of decide its mission set. no commander in the world would ever want a weapons system that decided what it wanted to do at a given moment. these would be preprogrammed rules, according to preprogrammed rules of engagement that are legally screened to make sure they meet the requirements of law of conflict. the machine may make cleaner decisions on the rules of engagement, which have been preset and preassigned on legal grounds, than a stressed pilot, who's trying to do a million things at once. that may be the case with a sophisticated military, but that's not necessarily what we're talking about here. if anyone has an ability to access a type of weapon that can selectively target a group of people,
just lay that framing onto all of the types of conflict that we see today. whether we think about conflicts within country, when we think about rogue states, when we think about terrorist groups, when we think about cartels, when we think about violent crime. now you're giving...powering those types of conflicts with a weapon that can target at scale, right? to me, that is a very, very scary future. autonomous weapons aren't a distance possibility. much of the tech needed to create them already exists and some believe that if humans can't get together to ban them, it could be one of humanity's greatest mistakes. that was james clayton. and i've been speaking to professor stuart russell, whose bbc reith lecture this week warned about the dangers of ai—controlled weaponry. the letter raised the possibility of children playing
with toy guns being accidentally targeted by the killer robots. he was involved in the original slaughterbots short film from 2017, which in itself was shockingly realistic. drones whirr applause did you see that? before it was premiered publicly, i showed it to some of my ai colleagues, right. when they were watching the ceo of the arms company demonstrating the capabilities of this new technology and the kind of uses that you could put it to, they thought this was a documentary. they didn't think this was fictional at all. your kids probably have one of these, right? when it premiered in geneva, actually, _ at the negotiations on autonomous weapons, the russian ambassador sort of sneered at this and said, "well, why are we even discussing this? "this is science—fiction.
"it won't be even possible for even 25 or 30 years." three weeks after we premiered the movie, turkish arms company stm actually announced a weapon and they advertised capabilities for autonomous hits on humans, face recognition, human tracking, all of the things that the ceo talks about. those genuine bots could exhibit the same kind of intelligence and autonomy that's in the film, i would imagine they would be manually controlled and flown into things? you might think that, but, actually, no. they are fully autonomous and the un has a report showing that they were actually used autonomously to hunt down retreating troops in libya in march of 2020. i think there are many different arguments people make. one is a moral one, that it isjust morally
unacceptable to turn over to a machine the decision to kill a human being. you can basically launch weapons by the million. enough to kill half. a city — the bad half. type in rough description of the mission, like you know, "wipe out everyone in this city between the age of 12 and 60." just characterise him, release the swarm and rest easy. - so you create this weapon of mass destruction that's more effective than nuclear weapons, cheaper, easier to build, easier to proliferate, and doesn't really leave behind a huge radioactive smoking crater. is the answer just always to keep a human in the loop? and is the problem with that which human? i think the answer is "yes." to disallow attacks where there's no human supervision, there's no human who's looking at the actual situation and the actual target and saying, "yes, this is ok."
even under the assumption that the machine is programmed by someone who has the best legal training and the most humanitarian ofaims, even in that situation, we face problems of not being able to make the decisions correctly. the problem is the idea of these slaughterbots, all the bits can be bought in a decent supermarket, probably with the exception of the small bit of explosives, so, what do we do? they're technically already available and how would you ever ban them? so, we ban many things that are already available. so, biological weapons — it wouldn't be that hard for someone with the knowledge to create a biological weapon, but we still ban them. chemical weapons are widely available in industrial products. the companies that make them are required to account for those products, to check that their customers are real customers
and not fake shell companies. companies that receive an order for 5 million quadcopters would need to check who's buying the 5 million quadcopters. we can do this in ways that will not be perfect, but will prevent the kinds of weapons of mass destruction that i'm most concerned about. hello and welcome to the week in tech. it was the week better.com's ceo had a better day than the 900 people he fired over zoom. your employment here is terminated. twitter closed thousands of fake china state—linked accounts pushing propaganda. and here's a look at nasa's latest crop of artemis astronauts, some of whom might take giant steps walking on the moon. it was also the week instagram announced a new feature to help manage time spent on the app. parents will be able to see, and possibly be horrified by, how much time their children spend on the app,
and set time limits, while teens get their scrolling interrupted by �*take—a—break�* reminders. it comes after leaked internal research suggested teenagers blamed the app for increased anxiety. researchers from mit's csail have found a new way to exercise the brains and bodies of soft robots inside a computer programme. welcome to the evolution gym, a simulator allowing large—scale testing of machine—learning algorithms who choose how to grow bodies to complete tasks like climbing and flipping. some are evolving like animals. and finally, those of us who've always wanted to swap hands for wheels are in for a treat! that's what researchers at eth zurich did with this, the newest iteration of anymal, its quadruple—legged robot. it simply locks its wheels when it needs to walk, but why walk when, with a top speed of 14mph, it can really even roll up and down staircases! that is a �*wheely�* good idea!
the pandemic�*s come with many a challenge, but at least for the majority of us, being at home actually means being in a place of safety, but not for everyone. calls and messages to domestic abuse charity refuge increased by over 60% between april last year and february this year. some have described the situation as an epidemic beneath a pandemic. this isn't an issue in the uk alone. in israel, domestic violence cases between partners quadrupled last year. i was michal sela. in 2019, i was murdered by the man who was my husband. this was from a campaign highlighting the issue, by giving a voice to those who never got the chance to speak up for themselves. we have been training our deep learning tools for quite a long time on hundreds of thousands of faces and videos, so it really understands really, really well how faces move.
it is able, when you give it a video of someone moving their face, to transfer all that movement to a still image. it understands where the different markers on the fac are, and what will look realistic, and it is very, very skilful at taking every little gesture, every little blink and adding it to that new image. we were able to take videos of famous actresses speaking, bringing their story to life, and allowing technology, our technology allowed it to transfer that to their actual image, so it appeared as though they were telling their own story. the shocking murder of michal saylor shook israel in 2019. her husband was found guilty of stabbing her to death in front of her young daughter. her case is not an isolated one. i spoke to her sister, who has become a leading voice
in raising awareness for domestic abuse in israel, setting up a charity, hoping to use technology to save the next murder victim. after it happened, - i had so many questions. how come it happened to us? how come i didn't see anything? why didn't she share nothing with me? i what was she going through? the biggest question, - could we have saved michal? could she be with us today? and you have actually taken your grief to start a charity and help raise awareness, haven't you? the head of this second campaign is shiran melamdovsky somech. the first time i heard her idea, to take my sister's picture and make her alive, i was shocked, i was like, "oh, my god — it is too hard." but then i thought again, and i told her, "you know what, shiran? "you are a genius. "this is what the world needs. "the world needs to be shocked!" what do you hope to achieve overall?
my vision is zero femicide per year. an ecosystem of hundreds of thousands of start—ups to save lives of women in their own homes. so we can beat this, we can combat domestic violence with technology, innovation, humankind. we have solved much harder problems than this. now, many of us may feel quite uncomfortable when we have to unavoidably walk home alone, especially after dark, so shona mccallum has been taking a look at some of the latest technology that is hoping to help keep us safe. there is always that thought at the back of your mind — will i get home safe tonight? between leaving your friends and opening your front door, there might be a time you are travelling alone. we might call our mum,
share our location on whatsapp, or have our keys to hand — anything to make us feel safer. but i am interested to find out is there something better? one in three women in the world experience violence at some point in their lives, and even more say they have been harassed or felt unsafe. we did experience being followed, we have cat—calling, and we did receive quite a lot of unwanted attention. we did see flashers quite frequently on our school run. experiences like that led emma kay to create walksafe, am app to help women map out a safer route home. so we have got our walksafe map, you and i are on our way home. what i can do is, i can have a look at our routes. i can zone out here and, as you can see, it will show me all where the recent crime data is. so that has been a recent pickpocketing. this has been where
an assault has taken place. looks like somewhere we would want to avoid, right? exactly. the app also has a feature called tapsafe, where you tap the phone to alert your friends orfamily that you feel under threat. but some might feel having this kind of information in your pocket could make you more paranoid. looking around this park, it is lovely and, yeah, i feel pretty safe, but, just a couple of hours later... ..and in the dark, things feel pretty different. and if you are getting assaulted, it is perhaps unlikely that you would reach for your phone and bring up a safety app. so i've travelled to the university of bath to meet the team who are developing a smartwatch app that senses distress by monitoring heart rate and body motion to send an automatic alert if you are under attack.
alert blares. i often feel scared when i am out walking or running alone. so when i saw that apple watches were being used to detect heart—attacks, i had a kind of light bulb moment and i thought, maybe this could be applied to women's safety? but as the team have discovered, it is difficult to simulate distress. we looked at loads and loads of police reports and loads and loads of cctv footage of people being attacked and we tried to find things that were common amongst everything, and we saw the struggling motion, the pushing motion, that kind of change from being very regular and repetitive to something that was very erratic. so they created a test which allowed them to collect the data to train an algorithm which could recognise similar events. 26 plus 58. this smartwatch tech is in early development, but if the team manage to crack it, it could be something
we see being used by women in the future. the bsafe app for smartphones is similar too. phone: all guardians alerted. the idea is an emergency alarm is activated by your voice, and then it automatically starts livestreaming video and audio to your chosen contacts and records what is happening. the company believes these recordings could be used in evidence in court cases, which are often hard to prove. making women safer on our streets should be a priority for all of society, and what is clear is that this huge problem cannot be solved by technology alone. but what i have discovered is that tech could have a role to play in addressing some of the fears that women feel on theirjourneys home.
for years, efforts in developing autonomous systems have focused on replicating the human brain through machine—learning, but one uk—based start—up thinks there may be a better model — the honey bee. engineers at 0pteran think nature has already solved autonomy, and they have been researching the brains of honey bees to derive algorithms to teach robots and drones collision avoidance. the honey bee is a fabulous visual navigator. they can understand the world they are in over a 10km radius. they can fly point—to—point and return to home, and they can share information with other bees in the hive. and then those bees can go to that location. that is exactly what robots need to do. we have robots in warehouses that need to move around and get to certain locations, and then come back, and then do that dynamically without bumping into other things or if the environment changes. we have the same in the air with drones, doing inspections.
self—balancing autonomous bicycles navigating around the streets. essentially, what is happening is that machines need to move more naturally. the system enables drones and robots to take panoramic views of the world around them, just like an insect would. then, like a honey bee, the sensing technology calculates the optic flow across the field of vision, considering any obstacles, and taking action to avoid collisions. the system has already been tested on drones and a robot dog named hopper. nature likes to solve things in the most simple way possible. it finds those solutions that stop you from having to do a lot of computation that you didn't need to do. one of the ways it does that is and how it perceives the world. so, every animal that we know of that uses vision to navigate works out the motion of the world around it. we call it optical flow. and that is exactly how
our technology works. and the company claims that basing algorithms on insect brains could be a more efficient way of creating ai. importantly, it would also be a more affordable method for lower—cost robotic applications and that is the market that 0pteran is targeting. the current approach to ai is fundamentally flawed because it is really based on a caricature of how real brains work. it is kind of a tiny piece of the puzzle that has just been scaled up and applied to lots of different data with lots of computing power. but that means it is very fragile. it doesn't work the way real brains work and it is very opaque. we don't really understand what it is doing half the time, and that is not a good enough solution for autonomous systems. nature has come up with weird and wonderful ways of doing things that humans could never figure out, so maybe there is a lot more technologists can learn from the other creatures around us.
that's it from us for this week. as ever, you can keep up with the team on social media, find us on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching, and we'll see you soon. bye— bye. hello there. temperatures were as high as 1a degrees on wednesday, and the rest of the week will stay mild. i suspect many of us, though, will continue to see cloudy skies like this. there was some sunshine, though, across a good part of yorkshire and lincolnshire on wednesday, but these areas with those clearer skies are starting a bit colder on thursday morning. mild elsewhere underneath that blanket of cloud. could be some mist and fog patches with those clearer skies across parts
of northern england, even down into norfolk as well. we'll see those mist and fog patches lifting, and the best of the sunshine more likely to be to the east of the pennines, in the north—east of england. a lot of cloud around elsewhere. there's a bit of rain and drizzle across northern parts of scotland, becoming more confined towards the northern isles. whether you've got the cloud or not, though, it's still a mild day for the time of year. temperatures widely in double figures once again. now, high pressure is building in across the uk. that's why it's so quiet, but that high pressure is bringing with it a good deal of cloud. now, the cloud could just be thick enough to give one or two spots of drizzle across more southern parts of the uk, whereas again a mild start on friday. a little bit chillier across some eastern parts of scotland, the north—east of england, perhaps even into the north west of wales, where there could be a few breaks overnight. but as you can see, not a great deal of sunshine on offer on friday. the winds are light in most places, just picking up a touch there in the far south—west of england. and again, it's mild. 8—9 degrees more typically across northern parts of england and scotland. this time temperatures
are starting to ebb away just a little. this weekend, though, we're going to hang on to the cloudy skies for most of the country. a lot of dry weather around as well, of course. limited amounts of sunshine means a limited amount of frost. it will be turning a bit colder as the weekend goes on. you can see we may have some sunshine across the north—east of scotland, perhaps west wales, into the far south—west of england, where there's a bit more breeze on saturday. but otherwise, it looks cloudy once again. and we may just sneak those temperatures across southern parts in particular into double figures. there's the area of high pressure. it's really taking a shine to the uk. it's not going to move very far at all during this weekend. so, again, the winds are likely to be light, but as you can see again it looks like it's going to be quite cloudy. that cloud could be quite low as well, so some mist and some fog potentially over some higher parts of the uk. and those temperatures beginning to drop away a little bit. it will feel a little bit chillier on sunday.
this is bbc news. our top stories: the 0micron variant deals higher cases in the uk and awarding of staggering cases to come. —— a warning. the doubling rate of 0micron in some regions is now down to less than two days and i'm afraid we are also seeing the inevitable increase in hospitalisations. seeing the destruction for himself: president biden goes to kentucky and witnesses the devastation caused by deadly tornadoes. when you look around here, it is just almost beyond belief. these tornadoes devoured everything in their path. the influential black author and feminist known as bell hooks has died at the age of 69.
