president trump's ban on travellers from seven mainly—muslim countries. thejudge, in seattle, said the restrictions could be lifted immediately while a full legal case was heard. the government is expected to launch a rapid appeal against the ruling. iran has condemned new sanctions imposed by the us and promised to respond. washington says the sanctions are a response to iran's missile test on sunday, and what it describes as tehran‘s support for terrorism. iran says the sanctions breach a deal under which it agreed to curb its nuclear programme. the president of the european council donald tusk has said good relations with the us remain an absolute priority, despite concerns about the policies of president trump. speaking at a summit in malta, mr tusk said transatlantic cooperation had, until now, been a key pillar of the free world. in around ten minutes you can see newswatch, but now on bbc news it's time for click. for decades, scientists all around

the world have been trying to create a machine that can match our intelligence. and nowadays artificially intelligent algorithms can perform many tasks much better than us. for a long time scientists have been the use in games like chess, drafts and go as a benchmark for testing ai. and that's because all these games have a certain amount of unpredictability built into them. namely, their human opponents. but this week the ai community has been celebrating a big win after a poker playing algorithm called liberatus defeated four top human players in a 20 day match of heads up no limit texas hold ‘em poker.

i've been using poker as a benchmark for 12 years. now the best ai has surpassed the level of the best humans in the strategic reasoning under imperfect information. but even at this big win is only a little step towards creating a general artificial. intelligence one capable of sophisticated thought across a wide spectrum of areas, and solving problems just as well as a human can. it's an incredible time. and it's very hard to forecast. you know, what can these things do? it's a hard thing to think through, and has really incredible possibilities. but it's, i think it's impossible to forecast accurately. speech has been another big challenge for al researchers. personal assistants and chat bots are becoming more sophisticated, but they so far can't fool us into thinking that they're human. but what if you thought you were talking to another person?

konichiwa. do you speak english? speaks japanese. would that make you more likely to trust it? and develop a relationship? well, two researchers at the london school of economics came up with an experiment to see if we would communicate better with al if its messages were delivered to us by a human. they call this computer human hybrid the echoborg. and to explore the concept, jane copestick found herself becoming an echoborg herself. the echoborg was inspired by research from stanley milgram. he is the professor behind the controversial experiments on obedience in the 1960s, to see if people would deliver electric shocks to others if instructed to buy an authority figure. milgram also studied body perception, to determine if we hold preformed opinions of other people based on their looks. by using hidden earpieces,

people could speak someone else‘s thoughts through their own body. the echoborg has updated this research for the 21st century, to see if people will react better to artificial intelligence. such as the messages from an online chat bot. if they are being delivered by a human. i'm in the first stages of testing this out by becoming an echoborg myself. i'm starting my speech shadowing practice. the first step in becoming a fully fledged echoborg. the professors have told me this process will take at least eight hours for me to get any good at it. i'm starting my first practice withjk rowling's harvard commencement speech. members of the harvard corporation and the board of overseers... by shadowing speech, i should be able to quickly repeat back the messages from a chat bot so people won't realise they aren't my own thoughts. it may seem something paradox, but there's horses in the cow... i did something and scuttled somewhere. now, to put it to the test, i'm meeting creator professor alex gillespie

at the london school of economics. hello, how are you doing? great to see you, coming. and kevin corti, who called in on skype. so with that go round your neck? that goes around your neck. first step. kevin is using a chat bot called rose, which is not preprogrammed. the most noticeable problem in becoming a convincing ai are the delays while rose thinks of a response to the question. where do you come from? i was born in san francisco. really? in united states. when were you born? couple of years ago. just a couple of years ago? are you a chat bot? i'm a human. i thought for a moment you might be a chat bot. republic of ireland and croatia and france. my brother's from ireland. really? a magical place full of rain and crazy people. she says.

well... that was... interesting. weird. what you notices, they tend to be quite disconnected. it takes each sentence as a stand—alone sentence. some of them will speak like they are artificial intelligence, and some of them will pretend not to be. so this one's pretending not to be. but although last time i spoke to which it said it was artificial intelligence. oh, it's confused. our final test for the echoborg was to bring it on stage in front of an audience of 700 people at the bbc future conference in australia. what a lot of humans find difficult... what is the capital of australia? canberra. 0k, good. and what is 235 multiplied by 676? i think it's 158,860.

that's pretty impressive. here and now. how do i know you are human, how do you know i'm human? because i believe. you believe? because i appreciate beauty. because people saw me in the room. go ask them. in fact, some of the audience members were fooled. one thought it was a real conversation with a human, not an artificial intelligence. based on my appearance. some people thought you didn't want to talk about artificial intelligence. that you were trying to avoid the question, they really thought you were trying to avoid the questions. someone even said, had it been a man would it have been perceived differently? i think so. without becoming fully fledged echoborgs, we are already giving a voice to artificial intelligence everyday. through the algorithms guiding our news consumption, to our shopping habits and online searches.

we're bringing al to life more and more. projects like the echoborg let us reflect on what this means for our ai future and perhaps even what it means to be human. hello and welcome to the week in tech. where are the gadgets? playtime was never like this in my day. i've been taking a look at some of the latest toys hoping to light up the faces of children and grown—ups. and, inevitably, a few of them could be found at london's toy fair. this looks like a drone in a cage and that's because it is. it's also a proof of concept for a toy that's going to be available later this year.

its inventor here is wearing this glove, which means you can control it via gestures. let's have a look at what it can do. it all looks pretty simple, but i know you've been studying robotics for 15 years, so there's quite a bit more to this than meets the eye, isn't there? yes, absolutely. once the science of gestures has been codified, and that's what we've been able to do, as you can imagine, we can bring all sorts of robotic toys out, and consumer devices. the brain itself is in the glove, in the secretary and electronics. and the algorithms embedded in the glove. the drone is merely a conduit for the gestures being recorded on the hand. there was also a clear trend towards giving kids a deeper level of control when it comes to toy gadgets. this is a robot that aims to help kids learn to code. they can operate it manually through the app, or setup sequences of the functions they'd like it to carry out. it's looks pretty raw when you've

got all these leads and buttons, so it really is giving kids a chance to develop something. i also recently got my hand on a drone that kids can programme, spending time tweaking code at a computer or using drag and drop blocks. i had a play around with some of the drone‘s functions. so maybe that shows who the real kid is. first of all i press w, which should get the drone up and running. this is a spot of that well—known activity, drone bowling. back a bit. we need to go down. down... other way round. no, no, back. oh yeah! is, the skittles are down here on the floor. and i've done it! it's notjust about flying, though, you may want to do a bit of driving. to do that, you swap the wings for wheels. last year we learned quite

how much of an appetite there was for augmented reality in gaming. how about adding a robot to the mix. and give the big kids a chance for some play, too. there is the enemy. if i can turn around quickly enough. trying to turn around. i'm going to shoot. that's it. and i've hit. this gaming robot, much like virtual avatars, becomes stronger as you use it. it's also customisable and upgradable, with the ability to add wheels or even take on another robot in the room. or if you want to get yourself moving, how

about a personal training robot? this prototype has limited functionality, but still managed to put me through my paces. not that it fought too hard when i decided i'd had enough. the full length of version is ready for you on iplayer. thank you for watching and see you soon.. hello. welcome to newswatch, with me, samira ahmed. later on the programme: this man was on our screens again this week. is the bbc giving nigel

farage too much airtime? and was coverage of the new us administration's travel ban balanced and impartial, or did it pander to a growing anti—trump hysteria? first, the prime minister's visit to the united states at the end of last week to meet president trump was the subject of considerable media analysis, not least the moment when the two appeared, briefly, holding hands. but some people were more exercised by a question put at a press conference by the bbc‘s laura kuenssberg. um, thank you very much, prime minister. mr president, you've said before that torture works. you've praised russia. you've said you want to ban some muslims from coming to america. you've suggested there should be punishment for abortion. for many people in britain, those sound like alarming beliefs. what do you say to our viewers at home who are worried about some of your views, and worried

about you becoming the leader of the free world? this was your choice of a question? laughter there goes that relationship! so did one question from a reporter have the potential to damage the special relationship? some thought it might have done, and that laura kuenssberg needed some lessons in diplomacy. here's jonathan chappel. i was left guessing the motives of asking such a provocative question to someone so easily provoked as donald trump. was the motive to undermine the embryonic relationship between the two leaders? or was it the bbc trying to make the news rather than simply reported? or was laura kuenssberg showboating her questioning skills? whatever the motives, asking that question to donald trump in that forum lacked emotional intelligence. had donald trump taken

offence at the question, it could have had an impact on the future health and prosperity of the uk economy as a whole. the bbc and laura kuenssberg are in a privileged position to be able to ask questions at press conferences like this.
