be concerned that at the data breaches we don't know about. they could use the information on their platform. the whistle—blower has been talking to the new york times, to the observer newspaper and to channel 4 news. he worked with this company, cambridge analytica, and he claims that 50 million facebook user profiles were acquired by this app. facebook pushes back hard and said there was no breach of its data. they said people, when theyjoined this app, they did so knowing that all of theirfriends this app, they did so knowing that all of their friends personal information would be tapped into. they are not updating the statement in the light of comments from the chair of the select committee as for cambridge analytica, i haven't heard from them this morning but they say they did not use any of the information that they harvested from this infamous app in the us presidential election of 2016 and

the only used legally acquired data from personal information fairly in all circumstances. joe lynam, thank you very much. the weather is causing severe travel disruption around the country. this snowy picture behind me was taken in llandrindod wells early this morning. more snow to come across wales. still warnings put out by the met office for the rest of the day, particularly across the south and west, and we will continue to seek showers falling across the north and east of england, and the central lowlands of scotland. parts of the northwest and northern ireland will seek drier and brighter weather. the greatest concern is 10-20 weather. the greatest concern is 10—20 centimetres, severe weather, and it will be blowing a gale almost as well. blizzard conditions and bitterly cold, treacherous conditions for those out and about.

and it stays bitingly cold overnight tonight, even though we start to lose a lot of the snow, it will be a ha rd lose a lot of the snow, it will be a hard frost, a penetrating frost for the south because of the strength of the south because of the strength of the wind. the good news is, things quietened down a little tomorrow as we have high—pressure moving into cut off the bitter east wind. this is bbc news — our latest headlines. snow and ice continue to cause disruption to road, rail and air travel in parts of the uk. some police forces are advising motorists to avoid non—essential travel. the foreign office has dismissed claims that the nerve agent used to target the former russian spy in salisbury could have come from the nearby porton down research laboratory. a man's been arrested on suspicion of attempted murder after a car was driven into a nightclub in gravesend, in kent. 13 people have received treatment for injuries. mps are asking facebook for an explanation, after accusations that profiles were used without users'

permission by a firm employed by donald trump's election campaign. now on bbc news, click. this week, we are looking at the future of work. but whichjobs will go to the robots? stock pickers? nurses? mine? file: mr victor sherlock of horsham has got a robot at the bottom of his garden and he's trying to teach it how to mow the lawn. artificial intelligence. everyone‘s talking about it.

over the years, we've seen it develop, we've seen it evolve. oh, yes! this is the watson that wonjeopardy. we have travelled the world to see ai that tries to treat cancer... it studies millions, or tens of millions, of examples from the whole assemblage of scientific literature. ..predict crime, understand the economy... show me companies with revenue between $25 million and $60 million. ..and save the world. so it might not yet have conquered diy... it is doing it — it's got the screw in. ..but we keep hearing how ai will change everything. technology will make man the more intelligent form of expression. however, it's the bad side of these algorithms that always seems to get the headlines,

the fear that tireless robots infused with artificially intelligent brains may one day do us all out of ourjobs. with interaction, with use, with feedback, it actually gets progressively smarter. from bots that can talk like us.... you want me to help you reset your sap password? ..walk like us, and even, perhaps, think like us. we have been warned that the fourth industrial revolution is coming. the biggest difference between this and the industrial revolution in the 1800s is the speed. millions of workers are on the move. so, what is going on? whatjobs are really at risk? what is the future of work? and we start with healthcare workers.

for almost 70 years, the uk's national health service has been a free service at the point of care. but that model is under strain as the population ages, chronic health conditions increase and resources shrink. a recent study by the royal college of physicians showed that almost two thirds of doctors think that patient safety has deteriorated, with one doctor saying "we are not robots. we are human staff with limits." but should the nhs be turning to robots to ease the strain on its human staff? jen copestake has been looking at how data—driven technologies could transform care in the nhs. could artificial intelligence help save the nhs? more people are looking at innovative ways to ease the workload of doctors and nurses. computer programmes can rapidly analyse huge quantities of information in ways humans don't have the time or brain capacity to do.

in 2016, click filmed google‘s deepmind at moorfields eye hospital. they were developing an algorithm to identify abnormalities in eye scans. now it has submitted its findings to a medicaljournal for review. it could mean its systems are more effective than humans at diagnosing eye disease. deepmind taught its machine—learning software using a million eye scans. i'm going to see three other projects integrating data collection and artificial intelligence for monitoring, automation and decreasing waiting times. dementia is now the leading cause of death in the uk. at the manor hospital in coventry, software is being tested to remotely monitor patients on its dementia ward. this is one of the rooms on the ward. it looks like any other hospital room, except in this one there are two infra—red illuminators and an optical sensor monitoring my movements, including when i'm asleep. oxehealth uses a standard digital camera and the tongue—twisting

science of photoplethysmography. every time your heart beats, your skin briefly flashes red. we can't see this but the sensor in the camera can detect these so—called microblushes. it even picks up my vital signs when i am hiding under a table in the room as the microblushes can still be seen on my arm. there is an alert if i leave my bed... announcement: oxehealth alert. ..and the nurses can click on a live feed to see what is happening and determine whether they need to come and check on me right away. for the staff, initially, when we were having what looked like a camera put in a box in a room, they were not happy about it. but when we actually spent some time with oxehealth, they've explained to them and they see how it's working, they love it. they love the fact that it's giving you an extra — an extra support. the project is in the pilot stage and is awaiting medical certification. the data collected is being analysed remotely by a team in oxford

and will be used to train the programme to be more predictive. we've never had this capability as a species, to constantly get heart rate, breathing rate, activity and routine data. there's no reason, as we combine, we fuse the data using artificial intelligence that we can't detect the onset of dementia or even it getting worse. we can see a world where we detect problems earlier, so you can stay in your own home or in the setting you're most comfortable in without being — coming into hospital. and that will save a huge amount of time. saving critical time was the motivation behind automating processes at nhs blood and transplant. 11,500 people receive a transplant each year, but 6,500 are on the list. every day, three people die waiting for a transplant. a lot of information needs to be sorted through to make life—or—death decisions. the nhs is now using public cloud technology from ibm to help maintain huge databases that used to be managed with a marker and whiteboard.

by working with some of this automated technology, we can ensure that we are making the best possible decisions and that our clinical teams are really thinking through the best clinical outcomes for all of the patients on the transplant waiting list, and that our staff, who are often working at 2:00 or 3:00 in the morning in a highly pressurised environment, needing to allocate those organs quickly, are supported by the technology that they use. collecting all this personal data has led some to ask if it is stored securely enough. one of the challenges we have in the public sector is a perception that maybe the public cloud isn't as secure as on—premises data centre, which actually is not the case. so we have an obligation, obviously, to many, many customers to ensure that the public cloud is kept secure and it's patched and it's maintained effectively. the fallout from it not being in that condition obviously is quite severe. in the future, the team hopes that artificial intelligence will be able to predict how long people will be on the waiting list for an organ. there is an average waiting time of two weeks to see a doctor in the uk.

this can come down to two hours if you register with gp at hand. you can sign up if you live or work within certain zones of central london. you have to give up your regular practice doctor and register with gp at hand's remote surgery. 26,000 people have registered so far. i had a chance to test it out, pretending i had a case of food poisoning. first, i went through a triage with a chat bot on the app, who recommended i speak remotely to a real—life human doctor. the doctor recommends further care and can even send a prescription to a pharmacy. the artificial intelligence in the app draws on billions of data points and can cross reference the latest medical research from journals and studies around the world. we use our artificial intelligence to tell you whether you need to see a doctor or not. of course, you're always free to choose to see a doctor anyway, but what we find is that 40% of the people will get reassured and understand what disease

they have and what actions they need to take, and stop there. but the app has faced criticism from the royal college of gps, who say that younger users are being cherry—picked for the service. nhs england lodged a formal objection to the apps planned roll—out beyond london. whenever anybody comes up with a great, exciting idea, they're desperate to see it rolled out everywhere. what i would say is we need to give patients safe care, fair care, and equitable care. if we roll things out too quickly without ensuring that safety and fairness, we run the risk of causing unintended harm. so it is wise and sensible that independent evaluations are now going on of these new technologies, so that patients can be reassured that they are safe and that they are fair for everybody. i think it's wrong. i genuinely think that the slowing down what people want, it's just not right. i cannot understand why people are hesitant. but often, it's because they're scared of new technology. they do not know what the consequences are. and that's right.

they need to check that and reassure themselves. there's nothing wrong with that. i've seen three ways companies are working with data to help with monitoring, automation and decreasing waiting times — all areas that could help an overstretched health service. could artificial intelligence help save the nhs? artificial intelligence is a really exciting development worldwide but never more so than in healthcare, and there are certainly some things that al can help us with — to plough through the masses of data that we already have and provide answers to the questions we didn't even know needed answering. but let's be clear, al's never going to replace that person—to—person interaction. that touch of a doctor to examine somebody, that looking deep into somebody‘s eyes and recognising that physical, social and psychological make—up of the person is what really matters, notjust their bleeding leg or their headache, it's much more than that and ai will be a very long time before ai comes close. do you think it ever will?

i will be stunned if, in my lifetime, ai ever replaces a doctor. that wasjen, and although we're seeing to see automation creep into the skilled workforce, we most often think of it as working in the low—skilled sector, where the jobs are very, very repetitive. but what about places in the world where they still have a ready supply of relatively low—skilled, but cheap human workers? you'd expect countries like china, for example, to be able to hold back the robot tide longer than most. well, not so. we sent danny vincent to a warehouse owned by the giant chinese online retailer alibaba. this is a 3,000 square metre warehouse. it's part of an operation that sorts and delivers 55 million packages a day that are shipped to over 200 countries around the world. products are packed and sorted here, usually by dozens of workers.

but recently, they had some new recruits. 148 automated guided vehicles navigate the floors of this warehouse. these agile bots can communicate with each other to avoid collisions and distribute the work amongst themselves — a bit like their human counterparts, who still take on the final stages of processing. li yan is a 28—year—old worker from south—western china. herjob now is, in part, done by these machines. she followed a family tradition of migrating thousands of miles to find better—paid work. translation: it saves me from walking to every shelf to pick up the goods. now ijust need to stand at the pick—up platform to wait for the robots to send me the goods. i don't have to constantly

walk here and there. they are part of a data system collecting information notjust about their environments, but also the sales patterns — understanding what sells more regularly, rearranging where products are placed, shaving off valuable minutes from overall delivery time. translation: in a traditional warehouse, it is purely manual. there are so many products, so the job for the human workers is very heavy. they could walk 50,000 steps a day. it's like finishing a marathon. here, the machines do all of that, making the work easier and more efficient. china has the largest workforce in the world but it is shrinking, and rising labour costs is making it harder for logistic companies to recruit low—skilled workers. china is already leading the development of dark factories — factories that need no human workers and can literally work with the lights off. but will automation replace

workers like li yan? translation: i feel these robots won't become my competitors, because apart from sorting out goods i can also do other work — i can monitor the system, take orders, and other work. i don't think they will affect me. alibaba and its partners say automation is an irreversible trend in china, but they say sectors like e—commerce were born out of innovation. online shops replace many high—street stores, but they insist their workers and machines will need to continue to work together. we are going to interrupt this broadcast with some breaking news coming into us here at the bbc. it is a world first, bbc click presenter spencer kelly has been replaced by a robot. it has been dubbed robospen and the artifical intelligence machine is apparently capable

of a whole host of emotions as well as understanding and writing stories and crucially, he neverforgets his lines. robospenjoins the now from the factory that created him. over to you. sounds like you said i was artificially intelligent. as a robot i am often asked to pose for photos and tv reports about al. while i am a humaoid robot, i am not intelligent. everything i am saying is written by a human. the point is, robots and ai are not the same thing. observe my articulated hands with four independent fingers powered by eight air cylinders. engineering arts has made a name for itself by making robotic performers, actors and communicators. which, according to will, is pretty much the only reason the world might need humanoid robots.

humanoid robots are great for entertainment and communication, if you want something that interacts with people, the best way to do that is to make something person—shaped. so if you think star wars, c3p0 — the robot that talks a lot, has a personality, doesn't do a lot of useful things. will and his team design and build robots here from scratch from the aluminium bones to the rubbery spines and plastic shells. while they are more c3p0, the next wave our way the next wave are way into the uncanny valley. oh my goodness, it has just come to life with the eyes there. you have seen silence of the lambs, haven't you? that is very eerie, that is. if you know what i mean. will is fascinated with how

the human body works and a lot of this research concentrates on making natural looking body movements that are also very quiet. it is something that he believes might find a place in the field of prosthetics, although he says there is still a lot of work to be done. i don't have a single precision part in my body. how can i achieve this level of precision with these organic, knobbly bones and bits of mushy flash. of mushy flesh. one of the biggest problems we have is that there is nothing as good as human muscle. so for all of this motor development that we have done, we don't come anywhere near to what a human can do. where you will see humanoid robots, you will see them in a commercial context, so you might go into a shop and you might see a robot in there that is trying to sell you something. don't worry about all the clever ai, that's really going to stay on your computer, on your smartphone, on a webpage. it's not going chase you up

the stairs any time soon. the artificially intelligent algorithms will is talking about could very well change, assist or replace some jobs. so what does that mean for the field of journalism? now this is the bbc newsroom and every minute of every day there are a lot of complex processes in place here. there are a lot of complex processes in play here. all of these journalists are taking in huge amounts of information from around the world, trying to work out what is true and what is not and then they are trying to turn those raw facts into something that is understandable for our audience. news stories. the question is, can some of the tasks people are doing be made easier or even disappear completely, thanks to ai. we've seen software like this over the years, tools that can turn swathes of dense data into text that is more

digestible to us humans. but they can only produce very specific types of reports, they couldn't cope with new, unstructured information and write beautiful prose. well, this week the reuters news agency announced that it is building its own new bit of kit that assists human journalists by looking for trends and facts using data and turning and facts in data and turning them into handy snippets of fact that the reporters can use. it is all about taking some of the legwork out ofjournalism. machines are good at certain things and humans are good at certain things and conversely they are both bad at some things. machines are good at going to mounds and mounds of data, being able to analyse it and detect patterns and they are not good at writing stories and they are certainly bad at talking to people. humans are good at exercising judgment, understanding what questions to ask and talking to people and not so good at digging through lots of data.

the idea is, you take what machines and humans are good at and put them together and make a much better journalist and much better story out of that. the bbc‘s editor of news labs is also looking at ways to turn some of those duller tasks over to the machines. so much of the work in journalism isn't actually about journalism, it is about logistics, for example we will want a transcript of these interviews. words you've spoken, written down. exactly. at the moment that is done by human beings, we are working on some software that allows a machine to do that for you. it is not 100% accurate but probably good enough to work out roughly where i am talking about the interesting stuff. we have a day's worth of interviews, where is the interview with me? so can we have facial recognition software that will allow you to put all your interviews in and find that bit that has me in it. that kind of thing frees up time forjournalists to be journalists. this weekend and next we will be

looking at whether al or automation will make ourjobs easier or take it away altogether, but it is important to remember that al and robots are different. yourjob might be safe from one, but not necessarily the other. i think what they are doing here is fascinating. nasty! but the moral of this story is that when you think of computers taking people's jobs, they are not going to look like you. it is already happening and it is software which is artificially intelligent and invisible. the onlyjournalists that are ever going to be replaced by humanoid robots are the ones that simply read words written by other people. hello humans, it's me. newsreading automoton lara 9000 and welcome to the week in tech. it was the week these low—cost 3—d printed homes were unveiled, thanks to a collaboration between texan start—up icon

and non—profit newstory. the hope is to eventually make possible building 600—800 square foot homes in under 2a hours for less than £11000. in other news, it is humans who are spreading fake news — not bots — according to new research on how stories grow on twitter anyway. mit researchers say it is partly because when humans share novel information their status goes up and false news tends to be more novel than the truth. another air taxi has lifted off, this time in new zealand. the quora can fly up to 100 kilometres, at 110 kilometres per hour and it doesn't need a human pilot. another one of my friends showing off. and finally, for some reason, humans love to try to invent robots that can replace theirjobs, but this time they've gone too far. just look at this thing. it's a robotjockey, apparently.

it can reach speeds of up to 30 mph and jump fences. maybe one day this will happen, but i am pretty sure it won't look like. it won't look like this. please listen humans, stop this madness, we have no interest in taking your stupid jobs! end of news. lara 9000 deactivating. and that's it for now. you canjoin us for part two of our special look at the future of work, next week. in the meantime, you can find a lot more from these guys on twitter @bbcclick and also on facebook too. thanks for watching. and as thesp would say... isn't it time you were leaving? yeah, we're off. hello there.

treacherous conditions out and about. the snow is coming thick and fast across parts of wales, south and west england in particular, where there are still amber warnings in force throughout the rest of today. but there will be snow showers elsewhere as well. those snow showers are blowing around in this strong to near gale force wind, making it feel really bitter, and really significantly reducing visibility. so lots of hazards, it's dangerous if you are out and about on the roads today. a slightly brighter picture for the north west of scotland and north west northern ireland, but still bitterly cold. some of the worst of the snow will continue to fall, moving west across devon and cornwall. across much of wales we have seen heavy snowfall through the day. more snowfall to come on that strong easterly wind blowing it around. we have already had 10—15 centimetres in places. snow showers continuing in northern parts of england, fewer than yesterday, and moreso across east anglia

and the south—east, fewer. could be snow showers around antrim and county down, but fewer for the north west of northern ireland and the north west of scotland, still some coming through in the central lowlands. we've had a good covering here and in glasgow overnight. tracing the snow, very slow easing westward, so it will continue to pile up another five or ten centimetres widely, but double that in places, especially on the hills. temperatures are nothing to write home about, akin with yesterday. maybe slightly less wind in the north. adding on the wind elsewhere, and it's another very bitter day with a penetrating frost to come through the night, because we will keep the strong winds across southern areas. as you can see, it will take a long time to lose the snowy weather in south—western areas and we still have the wind, and we still have the easterly wind, another cold and frosty night, could be some mistiness in the north. penetrating frost in the south because of the tightly packed isobars, the strength of the wind.

we slowly lose that on monday. high—pressure orientates itself across the north, so it allows a northerly wind as opposed to the easterly. we still have the easterly in some areas, but fewer showers to contend with and the return to work on monday, it will be very icy where we have had a lot of snow. it's bound to be the case. but we could see that melting tomorrow afternoon in the sunshine but it will again freeze overnight and we will have to wait until the middle of the week onwards when the temperatures are recovering. goodbye.
