but one thing you can do at shows like this is take the temperature and spot the trends. what is everyone talking about this year? the new boss of the show was in no doubt about the big talking points for 2023. there's two themes that have completely blown everything else out of the water. they've almost kind of zoomed out of nowhere, if you like. ai. if we're being honest, nobody was talking about al a year ago. now everybody�*s grandmother is an expert. we're in the sustainability village, which is the physical embodiment, if you like, of the fact that everybody is talking about eco sustainability, energy uses on your washing machine, power. of course it's easy to say your green, but harder to live up to. of course it's easy to say your green, but harder to live up to that branding. we'll visit one of ifa's more sustainable stands later in the programme. but that other theme — ai is also something that seems to creep in to lots of product slogans. ai has been in a lot of stuff for a long time. yes. how is it manifesting itself here this year in a way it hasn't before? yeah, well, i would say potentially it hasn't yet. i think where it gets relevant probably for the next year or two and then going forward for our large clients, samsung's and bosch, siemens, miller and those people, when proper intelligence gets into your machines and they can really start to influence your life. and i think there's going to be some revolutions in the home that happen once the power and the capability of ai really guess understood of ai really gets understood and built into the software and then the hardware of some of our home appliances. and after spending a little while with desdemona here, i am actually starting to believe that smart appliances of the future really could add at least a little personality to our homes. what can you tell me about the presenter of bbc click? they say the presenter of bbc click is an expert on all things tech and ai related. i can only assume there must be a robot like me. now, as we said earlier, although white goods are ifa's big thing, one of its big themes is green. sustainability was a big theme last year. of course it's a big theme this year and it's only going to get bigger until we solve the problem. the question is, are we any closer to that? as we know, the whole purpose of tech fairs like ifa is for companies to sell brand—new products. it's an industry that is heavily led by new versions, new versions of phones, for instance. we are being made like made to feel very negatively about ourselves that we just don't belong and we're not as cool or as amazing if we don't have all these gadgets. and that is something that i really had to put to the managing director of this massive new tech trade show that we happen to be at. we can be very sustainable by not buying new stuff. and yet here we are at a trade show full of new stuff. so, yeah, how do we balance those two? we obviously have got customers spanning the whole gamut of, let's say, durability and reliability. a lot of our customers pride themselves in the fact that their products are going to last a long time. i think are more enlightened customers realise that they're not really in a battle about, is it? have we shifted 1.2 million units this year versus 1.1? they're really in a battle for brand love. if you've got somebody that's so in love with your product, they're willing to repair it and tie up with elastic bands and reuse it as much as possible, that's worth, rather than going looking on the market again and potentially going to a competitor that's worth just as much. so i think that kind of re—use and repair can have an impact. and so it was that in a tiny corner of ifa's so called sustainability village, a small group of volunteers were asked here to encourage visitors to make do and mend. it's working. it's working! ingo used to be an electrician and when he retired, he occupied himself by fixing everything at home. then he set up his own repair cafe where volunteers breathe new life into broken electronics. in germany, the awareness of longevity of articles is growing and of repairability. people want to repair. the younger generation is rather looking for latest technology, latest design and rather prefers to buy new. i'm not criticising that, but i'm saying in terms of interest in repairing something, it's more prone in the older generation. have you repaired many things while you've been here? actually, five or six only. who comes to an exhibition with a broken vacuum cleaner? there is a reason that the repair cafe is run by volunteers. the labour cost of repairing these small items means that operations like this aren't usually commercially viable. this is an item of e20. the phone is an item of e6—800. but they're difficult to repair. they are difficult to repair, but they're... if you then spend e30 to open the unit, you can say, yeah, this is worth it. i want to keep my phone. for this unit, it's not worth it because it's more than the new one. so we have we're in this niche where the professional shops cannot really help. but in the future, legislation could help make it easier and cheaper to fix our goods than it is to buy new ones. in march this year, the eu proposed a law that requires more products to be more easily repairable even after their warranty has expired. and some european countries are already trying to encourage repair. france is leading the way quite a bit there. they have got this very interesting repairability index showing with a figure from 1 to 10 how repairable your product is. as a citizen, you can think, "do i want this because it's only a one? or "do i think i'm going to go for the other one that's a lot more repairable, which will make it last longer and be more worth my money." i think there's a lot that we can do ourselves to make choices that are actually more beneficial for ourselves, especially in times when life is just expensive. whether tech companies do give us more sustainable products may be a reflection on how much pressure we and governments put on them and given the importance of repair, i wonder if these guys will be given a bigger stall at ifa next year. and that is it for the short cut of click at ifa 2023. there's more in the long version that's waiting for you right now on iplayer and we will be back next year for this show�*s 100th anniversary. can't wait. thanks for watching. we'll see you soon. hello there. every day so far this week somewhere in the uk has seen a temperature above 30 celsius, an unprecedented run of hot september days. and if this 28 celsius recorded at castlederg on friday is confirmed, well, that would be northern ireland's hottest september day on record. but there is a change on the way this weekend. gradually, it will turn cooler. there will be some heavy downpours as that change takes place. and on the earlier satellite picture, you can seejust the first sign of a change. some areas of cloud pushing up from the south, also a frontal system sitting up to the north—west which will start to push towards the north—west of scotland as we go through the day on saturday. and those clumps of cloud pushing up from the south will provide some scattered showers, maybe the odd thunderstorm initially across western and northern parts. further south and east — look at that, 33 in london. it could actually be the hottest day of this spell. and then through saturday afternoon, we could well see some showers and thunderstorms popping up through east wales, the midlands to parts of northern england. there'll be quite well scattered, but if you do catch one you will know about it. a lot of rain in a short space of time and we'll see more showers and storms feeding up from the south—west as we head through saturday night and into sunday morning. so we could see some heavy thundery showers at the great north run. and i think the good news for those taking part is that it is not going to be as hot as it has been. so, yes, some scattered showers and thunderstorms as we go through the day on sunday. down towards the south—east corner, still some heat holding on. 30 degrees for london and for norwich, but more like 21 in belfast, 22 in glasgow. and that is a sign of things to come because as we head into the start of the new week, these very warm orange colours are replaced with yellow and blue colours on our airmass chart. something much, much cooler is heading our way now. as we head through monday, we will see a frontal system pushing southwards and eastwards some outbreaks of rain, some showers, some thunderstorms breaking out. quite a messy weather picture really on monday. but all the while, the warmth is going to be squeezed towards the south—east corner and further north and west, it will be turning cooler and fresher. so this cold front will be pushing its way south—eastwards through monday night and on into tuesday, taking showers or longer spells of rain with it. behind it, you can see the wind direction. the winds will be coming down from the north. could see some further very heavy rain actually feeding into northern parts of scotland. but even with some sunshine, a much cooler, fresherfeel, 15 degrees in aberdeen, 22 in london. so next week is going to be a very different week. the nights will be cooler as well. tuesday night into wednesday could bring temperatures down in to single digits, six degrees there. for example, in glasgow. a far cry from the very warm and humid nights we've been having of late and then into wednesday, well, actually, it's looking like a pretty decent day weather wise. some good spells of sunshine on next frontal system, perhaps just starting to push in from the west, but still with that much cooler feel, 13 to 20 degrees. these temperatures far closer to what we'd expect at this time of year. so wednesday's fine weather brought by this area of high pressure, but that's unlikely to last too long. it looks like further frontal systems will then push in from the atlantic. now, depending on the exact configuration of these weather systems, if you like, it may be that we continue to draw some relatively warm air into southern parts at times, but certainly nothing as hot as we've seen lately. and broadly speaking, through the end of next week, it looks much more unsettled. 0ur september heat—wave coming to an end. live from washington. this is bbc news. high—level arrivals in delhi. joe
