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 this is bbc news. with one of these, a games

the headlines: people in hong kong are voting console, and replaces in local elections for the first it with one of these, a chromecast ultra. time since pro—democracy protests began. turnout is estimated to be three times higher than the last vote, if you want to play four years ago, and there are long a game on a tv, that is. queues of people waiting to vote stadia also allows you to play at many polling stations. on a tablet, computer or phone. both houses of bolivia's parliament in theory it's capable have now approved a bill calling of producing 4k visuals. for a new general election. it plugs into the back of a tv no date for the poll was set. the interim president is meeting and then connects to a router. this then makes the connection opposition groups to try to end four weeks of violence that's with a data centre. followed the last election, which international this controller communicates with the router via wi—fi and allows me monitors said was fixed. to actually play a game. streaming a game is more difficult than president trump's lawyer and close streaming video, because with video ally, rudy giuliani, has said he's not afraid you have data travelling in one of being indicted in connection direction, from the with the impeachment inquiry. speaking on fox news, server to the viewer. he attacked those who've accused him of pressing ukraine to make with a game, data travels both ways. investigations into the family the inputs i'm making to control of presidential rivaljoe biden. 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. now on bbc news — click.

google claims its data centres use this week: could this be the future of gaming? special tech which helps avoid this, move over vin diesel, as well as recommending that users we're about to get fast and furious. 00:02:05,829 --> 2147483051:37:47,630 and are you ready for 2147483051:37:47,630 --> 4294966103:13:29,430 a debate with a robot? are capable of receiving particular internet speeds. so the minimum spec required for stadia to actually work is an internet connection of 10mbps 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 i. 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 avayas 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 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 —— so i didn't write the book for the gaming companies and social networks — they know 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. but 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. so today, it's social media. testerday, 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 or fom0 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.

and so, it is 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; time, 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 critical to teach our children to become indistractible. 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. now, every time that 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 that 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 in 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: but first, 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. the ai then generates a narrative from what it deems the most relevant information. and 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 that you have an ability to collect information or to perhaps get evidence and being confronted with the other side is taking things that humans already do as part of debating,

but it'sjust enhancing your abilities to do it 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. and 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 synergistical 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 that when you 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. hello. after a very wet day across parts of the uk on saturday, sunday promises to be a drier day, albeit with a lot of cloud and some misty, murky conditions.

but, briefly, we have a weak ridge of high pressure extending across the uk. still some rain to talk about at first on sunday, particularly for eastern scotland, still on the heavy side. slowly that heavy rain pushes its way across northern scotland, and eventually becomes confined to the northern isles through the day. quite wet and windy here. but elsewhere, turning dry across scotland, largely dry across northern ireland, england and wales, but with a lot of cloud and some mist, some patchy fog through the morning. that will be slow to clear, poor visibility in places, so any brightness really at a premium on sunday. but away from the northern isles, it's mainly dry, mild, 9—12 celsius the top temperature. and then our attention turns to the south—west, our next area of rain pushing into south—west england and south wales through the evening and overnight, not getting much further north and eastwards. quite a wet start to the week across south—west england and wales. further north and east, mainly dry, mild, temperatures not much lower than five or six celsius. but generally, the theme in the week ahead is for more rain. this is the set—up

as we go into monday. an area of low pressure, frontal systems pushing their way north and eastwards. looks like the heaviest of the rain on monday is probably going to be across england and wales. as it tracks its way north and eastwards through the day, it starts to become a little bit patchier. but there will be some outbreaks of rain into northern ireland. could pop up for a little bit across northern england for a time, into southern scotland. northern scotland probably escaping, mainly dry. some brightness and sunshine following on behind the rain across wales and south—west england, but also a few showers. but it is another mild day, 9—13 celsius. now, one area of low pressure pulls away into the north sea. here's our next one arriving as we go into tuesday. this has the remnants of what was tropical storm sebastien, so it's going to pep up the rain, strengthen the wind. the timings of this rain may well change as we go into tuesday, so keep an eye on the forecast if you can over the next 24—48 hours. but it looks like we'll see another spell of quite heavy rain at times, strong winds as well, particularly across wales and south—west england. some spells of sunshine

following on behind the rain, but also some heavy showers. so, all in all, it's a really unsettled and often quite windy day on tuesday. still mild, 10—13 celsius. bear in mind there are some warnings in place for the rain on both monday and tuesday. all the details are on the website. it looks like, as the week goes on, things do eventually turn drier, but also colder again. bye— bye.
