london stadium this morning. totte n he m london stadium this morning. tottenham play west ham. he has made three changes to the team that good afternoon. played under the previous manager jeremy corbyn has defended his who was sacked this week. he cuts a decision to remain neutral in any future brexit referendum relaxed figure and says he won't be if labour wins power. making huge changes but will be he told last night's bbc expected to improve the fortunes of a clubfinding question time leaders' special expected to improve the fortunes of a club finding itself down in 14th he wouldn't campaign to leave place in the premier league table. or remain in the eu. the labour leader said it would allow him to "credibly" carry out what voters then decide. new zealand have taken control of the first test against england, asjoe root‘s side toiled in the field on day three. ben stokes will rue his dropped catch of watling, spurning the chance to remove the batsmen on 31. how costly that would prove. things were looking good for england when henry nicholls went in the morning, but that was one of only two wickets to fall today. as watling went on to hold the black caps innings together, unbeaten on 119 as new zealand closed on 394 for 6, a lead of 41 runs. jofra archer struggling for pace on a pitch offering england very little.

i think in hindsight he has been used in the wrong way. i think he is notjust someone who comes in and bowls low and bounces. i think he is better than that. he has a terrific delivery when he pitched the ball further up. there was a big appeal for lbw and as it happened the ball was going over the top of the stumps, but i want to see more balls at that length. the lta have given away almost a thousand tickets for great britain's davis cup semi—final against spain this evening. it's in madrid, so they were attempting to even up the crowd. they'll need cheering on, against rafa nadal‘s spain, that's for sure — but the big question is, will andy murray be playing today? here's our tennis correspondent russell fuller. great britain against spain in the traditional hostile davis cup environment for the british team but what an opportunity to reach the final. who is going to be on the great britain team sheet? a former

davis cup player for great britain, former coach of andy murray, the suggestion, miles, from captain leon smith yesterday was that dan evans and kyle edmund are a little bit ahead of andy murray writes now. he was indicating that we will see evans and edmund play singles again full somehow do you see at? i'm not sure. we have been discussing it all day and morning. it must be tough to leave murray out. having said that, what a victory for dan evans and kyle edmund. they did it in different fashions but they will be buzzing. evans had had three tough matches and will fatigue take control? do you want murray playing a semifinal? it will be a hostile crowd and you need someone who can handle it. it needs to be counted on to win that first game of the day. do you send dan evans out? for all of his excellence yesterday, could he bea of his excellence yesterday, could he be a sacrificial lamb against rafael nadal? who is best placed to

beat other plays in the first match? that is the first question. it will bea that is the first question. it will be a tough task to take on an adult. if murray is fit and ready to play, he is the first player on my sheet. the evans, with a sliced backhand, we have seen in the past that there is another right hander who has had troubles with his wrist in the past. he deals with that slice well. i can we question is that if murray is ready play, i would put him on there and to take on an adult, he can swing freely with that big forehand. it may all come down to the doubles, it will be very lively inside centre court and we will have commentary on bbc five live sports extra from liz30pm. what a match ahead for great britain. that's all the sport. now it's time for click. this week: could this be the future of gaming?

move over, vin diesel, we're about to get fast and furious. and are you ready for a debate with a robot? streaming services have changed the entertainment landscape. they're taking bigger and bigger chunks from the dvd market, they've completely revolutionised the music industry, and they've got terrestrial tv execs quaking in their expensive boots. but what about streaming video games? well, that's a lot harder, because you need to make the game responsive and playable.

so could streaming ever kill the games console? this week, tech giant google launched stadia, a brand—new games streaming platform. you would no longer need an expensive computer or the latest game console to play the best titles. in theory, you only need a good wi—fi connection. or at least, that's the idea. marc cieslak has been putting stadia through its paces to see if it lives up to the expectations. google stadia does away with one of these, a games console, and replaces it with one of these, a chromecast ultra. if you want to play a game on a tv, that is. stadia also allows you to play on a tablet, computer or phone. in theory, it's capable of producing 4k visuals. it plugs into the back of a tv and then connects to a router. this then makes the connection with a data centre. this controller communicates with the router via wi—fi

and allows me to actually play a game. streaming a game is more difficult than streaming video, because with video you have data travelling in one direction, from the server to the viewer. with a game, data travels both ways. the inputs i'm making to control the game travel to the server and the graphics displaying the effect of my input have to come back to me. this is where a potential problem could occur due to a thing called lag. if the inputs don't match up to the graphics, then the game becomes impossible to play. google claims its data centres use special tech which helps avoid this, as well as recommending that users are capable of receiving particular internet speeds. so the minimum spec required for stadia to actually work is an internet connection of iombps download and imbps upload speeds. i have everything connected via wi—fi. are we ready now to consign our consoles to the bin? um, initially, no.

because as you can see, performance is, well... it's a little bitjuddery, a little bit laggy, and nowhere near as smooth as you would expect from a console. and there we have "your game may stop because your connection isn't stable." i'm inside the bbc building using a router which should be more than capable as far as this is concerned. so what is stadia like out in the real world? so we take a quick trip across town to check. i've come to a flat in north london, and i've got stadia set up here. we've quite a good internet connection here, about 20mbps, well inside the specification that should work with this device. now, it's a little bit of a faff to get it set up, because each one of these things, the controller, the phone, and the chromecast ultra which is plugged in to the back of that screen, has to connect

to wi—fi individually. it's quite impressive. it's smooth, it works, we're playing the game. everything's working properly. but after a little bit of time playing, i've encountered quite a few issues with performance. we get graphics sticking... this is actually working quite well now, it's actually settled down quite a bit. i should point out i couldn't get stadia to work on any public wi—fi, though, the kind of stuff you find in cafes and bars. there are a number of videogame streaming services already available, but stadia is perhaps the most ambitious. so far it has a list of 22 titles at launch, but only one exclusive, and while games like tomb raider and destiny 2 are solid titles, they're not exactly brand—new games. we have work to do. but perhaps the biggest challenge to google comes from microsoft, with its games streaming offering, which was on show at a recent xbox event. microsoft's response to videogame

streaming is project xcloud. i'm playing halo: the master chief collection on a mobile phone over a wi—fi connection. the crucial difference, i suppose, between this service and google stadia, is that this is currently in its testing phase — microsoft taking a very cautious approach. my view is we're all in the testing phase. we're early in this technology. we view it will take many years before this technology becomes mainstream. the best place for you to play will be on your local device connected to your tv, and that'll be true for many years. the same thing for a gaming pc. the local compute capability that you have, you're not dealing with internet irregularities, you're dealing with a dedicated device which is meant to go play those games, connected to a display device that is probably the best display device in your house. when it does work it is a minor miracle. both of them are.

it's amazing when you can just switch devices on the go, jump from your tv to your tablet or to your laptop, you know, that barely runs, you know, microsoft word and then suddenly you're playing destiny 2 on it. that's amazing, when it works. but it is a little off in the distance before it's sort of universally accepted as the new way to play. there's been a lot of confusion about stadia's pricing, with lots of people thinking it's a "netflix for games." it's not. basically, the user pays a subscription to access the service. all the games must then be purchased in order to play them. it costs £8.99 a month for a stadia pro subscription. this allows players to use the service and play games in ak at 60 frames per second. there are a host of features for stadia which aren't ready at launch, like sharing clips to youtube. but on this evidence, videogame streaming is surely the future. the problem is, today's technology isn't quite up to the task. that was marc.

now, last month we spent a whole episode of click looking at all—electric cars, and as part of that, we showed you just how quick electric cars can be. this was lara in a tesla saloon car outgunning a lamborghini. but electric ambitions don't stop in supercar territory. no, several manufacturers are working on electric hypercars. this is tesla's vision, this $250 , 000 2020 roadster is due next year. and here is the rimac c two. it has the equivalent of 1,888 horsepower, and it has a claimed 0—62 time of 1.85 seconds. and a base price target of $2 million. but both of those cars could be outgunned by a british—designed hypercar like none other,

and it's even more expensive, too. dann simmons has been to hethel in norfolk for what's hoped to be the rebirth of a legendary sports car badge. newsreel: chapman built his first car for fun. it was an austin 7 special. no—one knows why, but he called it a lotus. since the ‘50s, lotus has been producing lightweight cars designed to thrill, from the classic ‘60s elan to formula 1. commentator: 23 speed aces are on the grid at brands hatch to start the european grand prix. lotus has been specialising in affordable sports cars, offering 200, 300 or even 400 horsepower. but now, with new investors, its first foray into electric is as eye—wateringly expensive as it is powerful. and no—one has seen

anything like it. this car is the first all—british electric hypercar. it will be the most powerful production car in existence when it goes into production next year. it's a huge statement of intent, announcing that lotus is back. so we have four ps motors to deliver 2000 ps in total. that's german for 1,973 horsepower. to do that in this packaging we've had to take existing technology and radically improve upon it. what our engineers and designers have achieved is something which looks beautiful, but have done it as a form through function. every part of that design has a use.

these are the first pictures of the evija in action on a test track. while it's still being tinkered with, it's in camouflage paint. but the new poster child for lotus is notjust a pretty picture. the evija will have some truly astonishing abilities under the hood. so, there's no gears. there is a single box which means we have completely linear acceleration, from 0 to over 225 miles an hour. what that does do, is it gives us unbelievable acceleration. so we can go from nought to 300 kilometres an hour in significantly less than nine seconds. the low seating position is afforded by placing the 600 kilograms of batteries in a pyramid formation behind the driver's seat. liken a mid—mounted engine. those batteries are special, too. after recharging 1,000 times with mixed driving modes, performance dropped just 10%.

and in this car, with a conventional 350 kilowatt charger, you can go to 80% in 12 minutes and 100% in about 16 minutes. we're working with partners to develop ultrafast chargers, which means we could charge this same car in less than nine minutes, up to 100%, and in about six minutes, up to about 80%. that would be truly world—class. that's all very well, dann, i hear you say. but where do i put my luggage? well, how about the carbon suitcase that you fit just here inside the driver's door? there's also one on the passenger side, so you're not fighting for space. the downforce on this car can be increased fourfold, with the rear wing and undercarriage adapting according to conditions.

at £2.2 million each, just 130 evijas will be made, starting next year. but the tech behind them will be around for a long time to come. hello. welcome to the week in tech. it was the week iran enforced a near—total internet blackout following protests against rising petrol prices, leaving almost 80 million people without online access. britain's conservative party came underfire for rebranding one of its twitter accounts as "fact check uk," a move the social networking site said was misleading. and heliogen, a bill gates—backed start—up, claimed a breakthrough in its solar energy technology which could one day cut fossil fuel use. using computer vision, it was able to concentrate solar energy at temperatures of over 1,832 degrees fahrenheit. south korea's lg is testing out 25 of its chloe robots with seoul's national university

hospital. lg says the robots will provide video support to young patients ahead of medical procedures. an aquatic rover is being rolled out under the ice in antarctica. nasa is working with the australian antarctic programme to test the metre—long robot. it may one day help spot signs of extraterrestrial life on europa, one ofjupiter‘s icy moons. and finally, google has built a room—sized egg to help solve one of the hardest parts of 3d modelling, lighting. this 3d camera setup is rigged with more than 300 led lights that can produce any colour and create human models that will blend into their virtual environments. but will this bright idea take off? we're hooked on apps that demand our repeated attention, and it's no secret that the tech companies have used particular techniques to make their products

and platforms habit—forming. those videos that just autoplay one after the other, those stats next to your posts hinting atjust how popular you are. that notification icon — it's red for a reason, you know. red is a trigger colour. even the act of swiping down to refresh your feed feels like you're playing a slot machine, and the fact that you don't exactly know what you'll get as a reward... well, that's addictive too. to be clear, we want that, right? to be very clear, that's what makes a product engaging and interesting. are we going to say, "netflix, please make your shows less interesting!" "apple, please make your devices less user—friendly!" of course not, we want them to be engaging. a few years ago, nir eyal wrote hooked, a book which detailed these techniques to make company products more habit—forming, although he says he hoped they would be used

to form good habits. tech companies have been using these techniques for a very, very long time. the idea behind hooked was to democratise those techniques — why shouldn't all sorts of tech companies use these same tactics to help people form healthy habits? so i didn't like these for the gaming companies and social networks, they've known them already. what i wanted to do was help companies like fitbod get people hooked to exercising in the gym, companies like kahoot to get kids hooked to in—classroom learning, so we can form these healthy habits using the exact same techniques. whether it's fitnees or facebook, many of us are feeling hooked and now al has written an antidote — indistractable, a book to help us break our smartphone habits. poacher turned gamekeeper? maybe. today it's social media, yesterday it was television, video games, the comic book — all of these things people said were melting our brains and addicting us, and, of course, none of that has really happened.

his book deals with suggestions on how to resist the internal triggers like boredom orfomo that cause us to reach for our phones. i think we all have to face up to the fact that these big corporate moneymaking corporations are going to want to use every means possible to make us use their products more. that's just right. incorrect. really? yes. they do not want to create addicts, they want to create lifelong users. so it's a competitive threat to these businesses if people say, "this product is hurting me," and that's what people do with time if a product hurts them. we're not stupid, we're not puppets on a string. people realise that if this product sucks, i'm going to find an alternative and stop using it. in ten years, where do you think we will be? if you think the world is distracting today, just wait a few years. and this is why i think it's so crucial to teach our children to become indestractible. that is the skill of the century.

speaking of those skills, i've been taking a look and some of the apps and functions within our phones to help encourage us to spend a little less time looking at these screens. so how about the idea of being rewarded for the time that you spend away from your device? now, i get the idea that an app to do that is kind of ironic because it's on the phone, but apps like forest aim to create the right feeling that makes you want to not use your phone. the aim here is to build a whole forest one tree at a time. so each time you want to take a break from your phone, you set how long that is for — could be half—an—hour, could be ten minutes — and then you tap on plant. so a tree is being planted as long as i spend that time away from my device. every time you're tempted to go back and check your social networks, tempted to go back and play that game that you're so addicted to,

well, you have to actively tap ‘give up‘ to do so, which psychologically does make you want to put the phone back down and carry on with what you're doing. the ultimate aim here is to create a whole forest and, at the same time, you can track your progress to see each day, each week, each month how long you managed to stay away from your phone each day. you can even set up group tree planting, where if one person falters — you all fail. another way that you can spend less time connected to the internet is actually reducing the amount of time you can connect to your wi—fi. think of it as like parental controls but for yourself, and this can be done at router level. this is what's known as a mesh wi—fi system. it allows you to upgrade your home internet function, including setting rules about the times you can connect phones, tablets or computers to the web. and then you connect

all of your gadgets to the device, so you can select various functions — you can add antivirus but you can also go in and change those all—important timings. of course, the one big problem with this is you could switch to using your mobile data, so to avoid that temptation, you can switch mobile data off in those apps that are going to tempt you the most. but for those moments when fiddling on your phone seems pretty unavoidable, or simply irresistible, then another option is to switch it to greyscale, as those apps are going to look a lot less appealing, so you're likely to want to spend less time using them. creating the iphone shortcut is easy, and once you have, triple—tapping the home button allows you to switch the function on or off. it's a little bit more complicated on the android device, though, as you do need to enter developer mode. realistically, all of these

options do require a little bit of willpower still, and if you had enough, i guess you wouldn't need them in the first place. but hopefully, they are some help. right now, i think i need to get back to checking my phone. keep scrolling, lara, keeps scrolling! now, computer scientists around the world are working on ways to make artificial intelligence indistinguishable from humans, with varying degrees of success, but one way this is being tested is in debates between humans and computers, and this week ibm's ai system was on stage at cambridge university, and jen copestake was in the audience to see the results. cambridge union is the world's oldest debating society. in the past, it has hosted winston churchill, the dalai lama and theodore roosevelt,

but tonight's star guests are not human but artificial intelligence. project debater: the next issue is bias... ibm's project debater is the first of its kind in the world. a machine that can debate humans on complex objects. and in another world —first, it is here tonight to help to humans debate the motion ai will do more harm than good. project debater, these take the floor. applause project debater: ai will not be able to make a decision that is the morally correct one. the two project debaters are present in this single avatar using a female voice. each team's debater presents the opening arguments for the debate, which has been determined from over 1,000 contributions, something ibm calls speech by crowd. project debater: we will demonstrate how ai will automate repetitive tasks and the next issue will show how ai will create newjobs. the system sorts the responses into meaningful groups and identifies central themes and the ai generates a narrative

from what it deems the most relevant information. then the human team members take over to continue the debate. they peer deeply into our soul because of the amount of data we trail on an everyday basis. whereas with al, it's absolutely crucial. why? because without data, there is no ai. the fact you have an ability to collect information or to perhaps get evidence and be confronted with the other side is taking things humans already do as part of debating, but it'sjust enhancing abilities to do things much better. some abilities are just going be able to be pushed much further with the technology of our system. project debater: greetings, harish... project debater first faced debate champion harish natarajan back in february in san francisco. project debater: isuspect you've never debated a machine. and while losing the debate, the audience felt they had learned more about the subject from the ai and from the human champion. i think when you have access to far more information, it changes the way in which you think about the topic.

humans augment that by being able to talk about some of the emotional and moral issues, and i think at least at this stage, artificial intelligence is behind. the future is in a synergistic collaboration between the system and humans, and not in replacing humans. so you never think it will be sophisticated as a human in developing arguments? i believe when you're actually trying to use this technology, you should do that in collaboration with humans. in the end, tonight's ai—assisted debate was a tight—run contest — 51% voted against the motion that al would do more harm than good, with 48% voting for and 1% abstaining. so an ever—so—slightly upbeat view on the future of ai and human interaction in cambridge. that wasjen in cambridge and that's it for this week. don't forget that we live on, altogether, youtube, facebook, instagram and twitter — yes, correct — @bbcclick. thanks for watching

and we will see you soon. but some of that rain falling on saturated ground there is room for travel disruption and possible flooding as well. especially for north—east england and north east scotla nd north—east england and north east scotland as well. we have rain walking northwards across england and wales pushing into the south—east of scotland. could be some showers in the south—east later on. we have already had over an inch of rain across the south—west of being. it is damp out there today.

into tonight, the rainfall becomes focused across north—eastern parts of scotla nd focused across north—eastern parts of scotland but elsewhere looks pretty dry and certainly male to start of the sunday morning. sunday, we should see less cloud and some bright intervals trying to break 00:29:16,885 --> 2147483051:51:27,215 through that crowd. —— mcleod. 2147483051:51:27,215 --> 4294966103:13:29,430 goodbye.
