taiwan. an island shaped like a leaf but the meeting point of four seas. many around the world came to know it from the words made in taiwan stamped on electronics, toys and bikes. it became a brand people recognised. but the world has changed again. hardware is out, software is in. ai is the future, handsets are the past. stephen and i have been to find out what ‘made in taiwan' means in the 21st century. welcome to taiwan.

500 years back, taiwan was known as a pirate kingdom, a base for chinese and japanese entrepreneurs who traded in the south china sea. but more recently, it's chased legitimate business but still with an entrepreneurial zeal, leading the world of technology manufacturing since the 1960s. over 30 years, taiwan underwent massive industrialisation in what has become known as the taiwan miracle. huge tech firms grew, becoming household names. asus, htc, acer. at the centre of this was the semiconductor industry, led by a company you have probably never heard of...

..tsmc. it is the one of the largest semiconductor manufacturers in the world, producing chips in some of the best phones, including the iphone 11. it is most likely if you have a smartphone, you have something made by tsmc. and these chips were only made possible thanks to the discovery of semiconductors. why semiconductors are important or interesting? because it changes your life. with factories, or fabs as they are known across the globe, the largest is here in taiwan. and we have been granted exclusive access to see just how those chips that form the heart of our electronic devices are created. but before we can go into the fab, there was quite a process to undergo. i have to take my shoes off on the carpet. then put them in a locker, it seems.

and that was just the start. i had to put on a hairnet, wash my hands and wear this to keep the dust out. phew, but it is time for an air shower. i feel like i am in a tumble dryer! the manufacture of wafers has to be extremely precise. they cannot tolerate any particles because they fall onto the wafer then damage the chips. so finally, we were allowed in the factory and there was a good reason for all that faff. the speed of these chips relies on how many transistors you can cram into a tiny space. and when i say tiny, i mean tiny, i am talking nanometres. i don't really know how to describe how fine that 5—nanometre or 7—nanometre is but people often say if you look at 28 nanometres, it was like 1,000 of

the diameter of a human hair. in this fully automated factory, the lights are kept yellow to protect the product and the machinery is moving all around but there are quite a few things in here we are not allowed to film because this is seriously cutting—edge technology so it needs to remain pretty secret. we have to protect our customers‘ information. whichever way we can. so basically, we do not allow cameras to freely roam inside our fabs because, inevitably, they may pick up customer information. between all the automated devices in this facility, they travel 400,000km a day. devices in this facility, to put that into context, that is ten times around earth. all of this is about the concept

of keeping up with moore's law, as predicted by intel engineer gordon moore in the ‘60s. it refers to the doubling of transistors on a chip every two years whilst the cost is halved. a concept increasingly hard to keep up with, despite us expecting a lot more from our ever connected lives. the next driver is what we call ubiquitous computing. it is computation everywhere at any time. all the devices are connected. billions and billions of devices that are smart, that can compute at any time and communicate and link and that will be the future enabled by semiconductors. it's a future that's not too far away for taiwan. ai is making substantial progress here, especially in health care. i am here at taipei veterans general hospital where they are already experiencing the benefits of ai.

whilst many ai systems are hidden behind closed doors, in this hospital, we were given behind—the—scenes access. we have a patient actually inside the tunnel and he is scanned for his brain, to see any brain metastasises coming from the lung cancer. many of the patients who come here already have preliminary diagnosis of cancer so they come here with anxiety so our purpose is to diminish the guide anxiety, to treat anxiety and shorten the process. in the real world, i have to read the images one by one. it's pretty heavy physical loading work but with al systems, i can ask al to help

me read the images. but what could take a doctor a couple of weeks can be done by the ai in seconds. you can see how quick the images are uploaded for the system. and from the ai, you can see the lesion already there. and another one here. that time can make all the difference. beyond diagnosis, the ai is also assisting the surgeons with surgery decisions. already the patient has been stage four lung cancer. so he shouldn't be operated. why, though, has taiwan and this hospital managed to lead

the world in al? people in taiwan, we're proud of two things. one is computer science. the other one is medicine. all of our medical affairs was computerised for more than 20 years. is the fact that you've been collecting data over a number of years what puts you in a really good position to be able to put into practice a lot of this ai? oh, yeah, because we can train the machine. they can learn to write, make the diagnosis. so the imaging is the same you would have used before but it's at the point of diagnosis and the computer can now diagnose that instead of a doctor. oh, yes, yes. it's kind of a deep learning. everyone in taiwan has a health care card which is used

to access medical records. basically, once you have a card, you can use it everywhere because i think 99% of people actually use our health care insurance system as a means to see doctors so that makes all the data central in one place and you can imagine that if there is a database that has all the medical records, no fragmentation, that is the first step of ai. but the data can only be read if the doctor also inserts their card into this device. it is also like a key. and authorisation by the patient. otherwise i cannot access her information without her improvement. you can see this information. i can put my card here. you can see the ct, see that information. we also upload the image within 2a hours after starting. that's very convenient. so if she visit the other hospitals

or the primary care physician office, the doctors there can also access the same information like me. but it's notjust big hospitals using ai and health care. i travelled across town to a small start—up at the cutting edge of medical science. this brain tracking system is used to assess stress in the brain. and the likelihood of someone being susceptible to depression. over the last decade, many, many neuroimaging studies have proved that the brain activity of patient with depression have some abnormal condition. but this evidence is found by mri, not eeg. for mild depression, mri cannot find anything, but we can find the mild depression from eeg signal. that is, the brain wave signal. the cap is cheaper and, unlike an mri, portable. it aims to allow doctors to diagnose depression in a more scientific way.

and we use the ai analysis method to analyse the patterns of the data from the patients with depression and finally, we found some biomarkers and we can detect whether the person has depression or not with about 80% accuracy. the company hopes to launch the product next year and is also looking at how it might be used to identify alzheimer's, attention deficit disorder, and susceptibility to insomnia. welcome to the week in tech. it was the week that a device dispatched by samsung to send selfies to space came back to earth with a thud, crash—landing in a back garden in michigan, usa. thankfully nobody was injured. on a slightly safer note, the korean tech giant has teased a flip phone — how very early noughties of them,

with a foldable screen. let's hope this one's more successful than its last attempt at a folding phone. twitter has banned all political advertising worldwide on its platform, saying the reach of such messages should be earned, not bought. the move puts pressure on rival social media outfit facebook, which recently ruled out banning political ads. in other facebook news, the social network has agreed to pay a £500,000 fine issued by the uk data protection watchdog over the cambridge analytica scandal, ending a year's worth of legal wrangling over the issue. as part of the agreement, facebook has made no admission of liability. facebook subsidiary whatsapp is suing the nso group, an israeli surveillance company, alleging it created various whatsapp accounts and caused malicious code to be sent by its servers to over 1,400 mobile devices for the purpose of spying. the nso group said it disputed the allegations and would vigorously fight them. and finally, an american company has

developed a pair of smart glasses designed to improve concentration and prevent distraction. narbis claims sensors in the smart specs measure the wearer's brain activity. if they decide the wearer isn't paying attention, the glasses darken, preventing them from seeing the distraction. the glasses will cost $690 when they launch in december. back in taiwan, one of the biggest causes of healthcare problems is pollution. and there's a lot of it — as stephen can smell and see. this is taipei's famous, or perhaps infamous, scooter waterfall. it's one of the main routes into central taipei for thousands of commuters every day. it is mind—boggling how many mopeds there are here. thousands of them, and theyjust keep on coming.

and you know what? you really get a sense ofjust how much pollution that these guys are probably causing because it stinks, it's horrible, and i think when you're walking around the city, you don't notice but here, you really get a sense of it. it's really quite disgusting. it's not often that you can see, smell, and even feel the pollution in a place. this is an extreme example of a problem that's a growing issue not only in taiwan, but around the world. imagine sitting at a stop light behind a gas scooter that is puffing, you know, puffing just toxic gas into your face just every day. this is what people have to go through every day because they didn't have any other option. air pollutants will affect your health, especially for the respiratory system. pollution and congestion is becoming a very big problem for us as everybody is moving into cities and living on top of each other. so i've come to taipei's institute of information science to find out how they're tackling air pollution here in taiwan. dr chen is one of the founding

researchers behind airbox. the idea is pretty simple — help people better understand and tackle the pollution around them by teaching them to make their own diy, low—cost air sensors. since launching in 2015, they've built a network of thousands of community—run air—quality sensors across the island. initially, when people started to use the local sensors to sense their environment, they found a lot of interesting findings which are never reported by the governments. so, initially, the government doesn't like the results. but finally, theyjust realised, well, this is the real environment people are living in. today, there are over 4,000 of their pollution sensors around taiwan, including one in every

primary and secondary school. some schools may change the schedule, so if the air pollution is more severe, then they will cancel the outdoor activities. research like this has revealed that there are a few major sources of pollution in taiwan. the usual suspects like industry, power generation, and transport, but also a few surprises — things like pollution blown across from mainland china, and some sources you might not expect at all. in changhua, also in central taiwan, there are some new devices that always show you a purple colour. that is very bad. and the reason? so someone reported the reason is the temples. 0h! they went out to investigate and they found the source. well, by going out and taking a look, the community discovered the culprit — traditional incense burning. well, by going out and taking a look, the community discovered the culprit — traditional incense burning. you know, in taipei, the two major temples, the longshan temple and the qingshan, there is no incense burning any more. 0k. yeah, because they also install airbox.

and then after some observation, they decided to cancel. so it makes a real difference, knowing about the impact? yeah, right. solving a problem like pollution almost certainly means changing the way we do things as humans. remember this place? well, this is the same spot a few weeks later. believe it or not, a big chunk of those bikes are not producing any pollution at all. this is a publicity stunt for gogoro, a taiwanese start—up that is pioneering the uptake of electric scooters in taiwan. taiwan has the highest density of scooter per capita anywhere in the world. as everyone‘s moving into cities and living on top of each other and the need for adopting electric transportation as a cleaner mode of transportation. but here comes the problem — chicken and egg, right? without the proper infrastructure, nobody would ever adopt a mobility solution that is electric, because charging in these big cities is next to impossible.

and this is gogoro's solution to that problem. riders own special electric bikes, but not the batteries inside them. instead, when they're running low on power, theyjust visit a station like this to swap out their flat battery and pick up a fully charged one. a subscription of around $10—$30 per month gives you access to any of the 1,400 swap stations around taiwan. the more you pay, the further you can go. so eric here has very kindly agreed to give me a ride around the block on one of their scooters. and you know what? it does feel a little bit different. the sound is slightly different, there's kind of a higher pitched whine, rather than the chug of a motor. and otherwise, though, it feels pretty much like a normal moped. i visited gogoro's head office, just as they were getting ready to launch their latest, top—secret scooter. this is our new baby.

right. with a lighter weight, colourful designs, and a grab bag of accessories, gogoro is trying to expand the reach of scooters beyond traditional riders. but, with a price tag of around $2,000 and just one battery instead of two, it might not be for everyone. the fact that the range is a bit smaller, do you think that matters? we see people riding about 15—20 kilometres a day on average in taiwan. this vehicle can provide about 70—80 kilometres. so you are talking about three or four days between swaps. we think that's plenty. gogoro estimate that their customers have saved 80,000 tonnes of c02 between them — that's roughly 25,000 across—the—world flights. there's no one magic solution to society—wide problems like pollution, but it's encouraging to see how taiwan is leading the way on finding some new ideas. taiwan doesn't look like a place with a population crisis but for many, too much hard slog has

meant too little time for family. some hope for a traditional solution. in taiwan, the children are getting less and less, so we worry about that. so if we want to be a family, you want to find a boyfriend or a girlfriend and get married. this is city god temple, where we've got a famous guy, he's a matchmaking guy for love. so that's why so many young people come here and pray for a good marriage, happiness. every year, we got 6,000 couples, they success. others have turned to tech. the hugely successful singaporean dating app paktor has been going strong here. in taiwan, people have no time for their personal life, especially in the tech company. during work, they are not even to bring their phone

in their company, either. so it's really hard for them to have a normal social life. as i met some of those leading the way in taiwan's start—up scene, it became apparent that, especially in the hardware business, historically, expectations on staff have been high. any call you receive, you probably need to answer the call and go back to the fab. most of the time, you're working six days or six and the half day, and the others you still need to be on call, so it's more like 24 hours. but times are changing. the work—life balance is very, very important for this young generation. and international influence is often at loggerheads with maintaining taiwanese tradition. taiwanese people are humble at heart. it's built into our

confucius belief system. when you manage a us engineering team, what happens is usually yourjob as manager is to try to get everyone to argue and agree on something. in taiwan, the issue is trying to get people to argue in the first place, just because they don't want to offend people. they think that their boss should be smarter, more intelligent than they are. but that's just not the case. there have been many positive steps forward, though. the education rate is rising, especially for females. so females are more getting to theirjob, rather than family. we're starting to see this very interesting cultural shift where entrepreneurship, starting your own business, is actually a viable pathway to actually sustain a family here. but even for those who have made it, innovation still comes with its challenges.

the shared economy, when it first evolved in the bay area, you know, with airbnb and other types of businesses, it was more of a disruption kind of statement — you disrupt the kind of existing economy, or existing infrastructure. it's much more difficult to do that in taiwan because it's very frowned upon. because there's not a law for it. you don't try to disrupt the industry first. that's it from click in taiwan. it seems that exciting times could lie ahead, plus hopefully a solution to this pollution problem. throughout the week, you can keep up with the whole of the click team, wherever they are in the world, on instagram, facebook and twitter at @bbcclick. thanks for watching.

hello, we started the weekend off on a pretty wild note, severe gales across southern parts of britain, leaving disruption and some damage, also heavy rain, with fresh flood warnings enforced. today looks calmer, this area of low pressure will continue to thin and weaken. for the rest of the afternoon, dry for most, plenty of sunshine around, bit of rain across north—west england and towards eastern

scotland. the area of low pressure will begin to sweep in, bringing showers and long spells of rain across england and wales, some of it can be quite heavy, wind picking up across the south coast and through the channel, breezy, wet, for the east of scotland, in between, some dry spells, temperatures ranging from five to 9 degrees. starting the new working week with another area of low pressure, slap bang on top of us, and in strong winds to the north, strong winds to the south, lighter wind in the core, plenty of showers spiralling around. some of these could be heavy, helps even a rumble of thunder mixed in, frequent across the south coast. windy once again particularly in the south—west, windy and wet across

eastern scotland, rainfall total starting to mount up. best of the sunshine for western scotland, some shelter there, temperatures 11 to 13 degrees. 0n shelter there, temperatures 11 to 13 degrees. on tuesday, subtle changes, low pressure slipping away, taking showers with it, increasing amounts of sunshine. wind will be coming down from the north, allowing cooler airto move in. down from the north, allowing cooler air to move in. struggling to get above double figures. 11, 12s, 13s in the south. wednesday, blue colours migrating south across the uk. it will turn quite chilly for a mid for most of us. temperatures in single figures, showers, longer spells of rain at time as well. —— and longer spells of rain at times too.

good afternoon. the leader of the brexit party, nigel farage, has announced he will not be standing as a candidate in the coming general election. he said he'll focus instead on touring the country to support his party's candidates. it comes days after he offered to form an electoral alliance with the conservative party, an offer which was quickly rejected by the prime minister borisjohnson. here's our political correspondentjessica parker. walking into this election, nigel

farage
