00:00:04Did of I do the right thing? Should I
00:00:07in go see doctor? What should I cook for
00:00:10dinner? People are turning to artificial intelligence as a
00:00:14constant companion, chatting with it almost like it's
00:00:17a close
00:00:19a friend. But what is AI actually good
00:00:23at? When should we trust it, and when should we be more
00:00:40career decisions, replacing psychotherapist or even a
00:00:43of friend,
00:00:43in whatever the problem, artificial intelligence always seems to have the
00:00:47right answer, but Hamburg-based AI researcher
00:00:51Maximilian Keeneer encourages his students to think critically about
00:00:54AI responses. Die wachsen jetzt in
00:00:58einer. machine instantly answers any
00:01:01question, that's Maximilian Keaner's avatar
00:01:05talking, the researcher programmed it himself, thereby making
00:01:08himself replaceable, at least according to the
00:01:11AI. I could handle your
00:01:14emails, your
00:01:16of reports, even this interview, and honestly I do a pretty good
00:01:18job, yeah, maybe emails, that's just
00:01:21optimization, but talking to students, interacting, showing
00:01:25empathy, taking
00:01:27of responsibility, you can't do that, you're
00:01:28of just imitating.
00:01:2930
00:01:45of
00:01:52of
00:02:05photos of
00:02:06every
00:02:11single cherry down to the smallest detail and that's no problem for
00:02:15AI, but cherries aren't
00:02:17people. what
00:02:20AI simply can't do is make value
00:02:23of judgements, which career path should I choose, the law, medicine,
00:02:27something
00:02:28of else? there isn't one correct answer. It's not a
00:02:30calculation, the problem we keep
00:02:33of running into is that we try to squeeze every complex problem into an AI
00:02:37format, das KI Format drücken
00:02:40wollen. In Keino's view, ethics doesn't slow down the development
00:02:44of AI. It's what makes AI genuinely useful for people in the first
00:02:48place. A team from the universities of Hornheim and
00:02:51Bamber has developed an AI that doesn't always have a quick answer.
00:02:55This socratic AI openly admits when it isn't entirely
00:02:59sure.
00:03:05a
00:03:14questions leads to
00:03:16Asking follow-up more balanced responses
00:03:17of and helps build trust, especially among professionals.
00:03:21A study found that doctors, for example, often remain cautious about
00:03:24AI. That's because experts can sometimes underestimate what
00:03:28the technology is actually.
00:03:34of
00:03:40AI of deep fakes like these have become very convincing in recent years and
00:03:44as computing power continues to grow they're getting even more
00:03:47realistic. the same goes for deep fakes circulating on the dark
00:03:51web, but is that really innovation? just because
00:03:55something's new doesn't make it innovation, there has to be value in
00:03:58it. for
00:03:59of example,
00:04:16of
00:04:30calculations, but Kina says humans still need to make the
00:04:33decisions. It's
00:04:37easy to forget what's really happening when we ask AI a
00:04:41question. Behind every answer is vast network of
00:04:44computers housed in
00:04:47of massive highly secure facilities protected from dust and
00:04:50heat, and nowhere has more
00:04:53of them than northern
00:04:54of Virginia in the US, just next to Washington
00:04:56DC. They take up enormous amount. of
00:05:00space consume huge amounts of electricity, and
00:05:04they're not just an isore, they're pretty noisy
00:05:07too.
00:05:12Pirio first stepped outside the home he just bought in 2012,
00:05:16he was surrounded by greenery, but where there was once a
00:05:20forest, there's now data
00:05:22center. It's really frustrating, we you
00:05:25know uh, how they how they could have voted to change the
00:05:29zoning to allow this so close to a neighborhood is beyond
00:05:33my comprehension. It's not just the view that's
00:05:37changed, the soundscape has
00:05:39too. just such
00:05:43annoying sound of angry
00:05:46because it will reduce the prop the
00:05:50value of our properties here, angry
00:05:53because it chase the wildlife away from
00:05:57us. the area in northern Virginia has become a
00:06:00global hub for data centers where the information that powers giant
00:06:04companies such as Uber, Netflix and Amazon as well as from AI
00:06:08applications is stored and processed.
00:06:12centers in particular require enormous amounts of
00:06:15electricity. these are data centers,
00:06:19look that direction, that direction behind us, all three
00:06:22sides. Elena Schlussberg is also
00:06:25frustrated. At Virginia's more than 600 data
00:06:28centers, 260 are concentrated in just two residential
00:06:32communities. In the 1990s, the area was home to
00:06:36AOL, America's first major internet service
00:06:39provider. Today it's at the heart the AI boom.
00:06:43Look, see another American flag. We're all a part of America when we're building
00:06:47out uh, the wealthiest industry in the world and paying for their
00:06:50infrastructure. Northern Virginia leads the world in data
00:06:54center concentration, accounting for 14% of all data
00:06:58centers globally. Running those facilities
00:07:02doesn't require many workers, but it does consume vast amounts of
00:07:06electricity, and that's having an impact on
00:07:09local residents. Communities are in direct. competition
00:07:13with industry that has an unprecedented
00:07:17need for power and water, and so those things that you normally rely on
00:07:21your affordable, clean energy is now being
00:07:25consumed by this one
00:07:27customer, and that's why you see your utility bills
00:07:31increasing. electricity prices here have risen by
00:07:3530% in just five years, the enormous demand for
00:07:38energy is one major downside the AI boom. so
00:07:42it looked as though it was matter of economic development and a good thing for
00:07:46the community, but they did not think through the
00:07:49implications for the ordinary rate payer. industry often
00:07:53needs a certain amount of power, but it tends to be
00:07:57distributed and the increases are predictable and
00:08:01measurable. there's almost nothing that compares to
00:08:04this in the past. but there are locals who are
00:08:08benefiting. some residents have joined forces to sell
00:08:11farmland for the... construction of data centers and power
00:08:14plants, mine has been a family
00:08:18farm for generations and
00:08:20unfortunately my kids and grandchildren have
00:08:24absolutely no interest in it, and we came up with a win win
00:08:28solution, the county is going to make money, the
00:08:32um, which helps them pay other people, all their
00:08:35employees more money, get better parks, get better schools for
00:08:38everyone, and yes we're going to make money.
00:08:42more than $1 billion tax revenue every year, and
00:08:46construction continues around the clock, but that growth comes a
00:08:49cost. Depending its capacity, a single AI data
00:08:53center can consume as much electricity as
00:08:56an entire
00:08:56city.
00:09:00Keeping buildings cool already accounts for
00:09:03more than 10% of global electricity consumption, and
00:09:07demand is only expected to rise. Researchers think they
00:09:11may have found a way to dramatically. reduce the energy needs for air
00:09:14conditioners. They're developing new cooling technology that
00:09:18uses special metals that heat up when stretched and cool down again
00:09:22when released. Only enough room
00:09:26for a single soda can, but this mini refrigerator is packed with
00:09:29innovative technology. Researchers at Zalland
00:09:33University in Southwest Germany have built it to demonstrate a new calling
00:09:37method that could be more energy efficient and
00:09:39climate-friendly.
00:09:44We need less energy for cooling, that means lower energy consumption
00:09:48overall, which ultimately means lower CO2 emissions
00:09:51globally. This cooling system uses
00:09:55very little electricity and doesn't require environmentally harmful or
00:09:59flammable refrigerants, but how? The key
00:10:03lies in bundles of fine wires, a bit like artificial muscles that
00:10:06rotate around the cooling chamber. They're made from a shape
00:10:10memory alloy. engineered to return to a preset
00:10:14shape after being deformed.
00:10:17is a professor of smart material systems at Zaland
00:10:20University. He uses an infrared camera to show us what's
00:10:24happening. The thermal image reveals the hidden superpower
00:10:28the nickel titanium wires under tension. It's the same
00:10:31phenomenon seen a balloon, a phase
00:10:34transformation. The atoms arrange themselves
00:10:37differently depending on the temperature and the mechanical stress in the
00:10:40material. So when I stretch this bundle of wires, I force it into
00:10:44different phase. The atoms reorganize
00:10:47themselves. That creates a different energy state, heat is
00:10:51released and the material warms up. When I release the tension.
00:10:55the atoms rearrange themselves again, we get different energy state,
00:10:59heat is absorbed and the bundle cools down again. this is known
00:11:03as an elastocaloric effect. it can create temperature differences
00:11:06of up to 40 degrees celsius within the material. the phenomenon
00:11:10is well known, but only recently have researchers tried to harness it for
00:11:14use in refrigerators and heat
00:11:16pumps.
00:11:21how do we transfer the heat and cold that we generate to where it's actually needed?
00:11:25In a fridge, we need to bring the cooling into the interior and release the heat
00:11:29into the surroundings. Here,
00:11:33circulating air passes over the cooled wires, then flows round the
00:11:36cooling chamber circled in blue, causing the contents inside to cool
00:11:40down too. The team from Zarbrucken demonstrates the
00:11:44technology with this mini refrigerator at trade shows and
00:11:47conferences. However, its compact design limits its cooling
00:11:51performance. Drinks inside can only be cooled to about 12 degrees.
00:11:56The team has also developed more powerful prototypes with cooling
00:12:00capacities of up to 250 watts, roughly what an average fridge
00:12:04needs, but in computer simulations, electricity
00:12:07consumption is about half that of comparable conventional
00:12:10systems. The technology is slowly gaining
00:12:14momentum. Startups around the world are developing caloric heat
00:12:18pumps and refrigerators. Both the European Commission and the
00:12:21U.S. Department of Energy see enormous potential.
00:12:25air conditioners are becoming more common in households around the world, in India for
00:12:29example, and they consume huge amounts
00:12:33of energy. The world's roughly 1.6 billion air conditioning
00:12:37units account for around 30% of global electricity
00:12:40consumption, according to estimates from the international energy
00:12:43agency. That figure has at least tripled since
00:12:461990. Researchers at the center for
00:12:50mechatronics and automation technology in Zarbrucken are convinced will need
00:12:54innovative.
00:13:25But that goal
00:13:26is still a long way off. For now, the latest prototype is tackling
00:13:30different challenge. The nickel titanium wire bundles wear
00:13:34out over time. Depending on the alloy and the amount of force
00:13:37applied, they can withstand anywhere from tens of thousands to hundreds of
00:13:41thousands of cycles. The new replacement cartridge makes
00:13:45swapping them out relatively easy. In this case, just 28
00:13:49grams of nickel titanium wire provide roughly 100 watts of cooling
00:13:53power, more than enough for the small.
00:13:59The technology is very well suited to places that need to be clean, the
00:14:03air passes directly over the wires and releases into the room without causing
00:14:07any problems. The Zarbrukan team believes it
00:14:10cooling systems could find a market in niche applications such as lab
00:14:14equipment. They believe the technology could be ready within 2 to
00:14:183 years, but they estimate it will be at least another
00:14:22decade before consumers can start replacing. conventional
00:14:25refrigerators with elastocaloric
00:14:27systems. As
00:14:31temperatures rise around the world, so does the risk of
00:14:34wildfires? Particularly vulnerable are canniferous
00:14:37forests, dominated by a single species and trees the
00:14:41same age. One solution could be more resilient
00:14:45mixed forests, but choosing the right trees to plant for the
00:14:49future is a complex task. Forest owners have to
00:14:53think decades ahead. AI help them make those
00:14:56decisions?
00:15:02what i plan here today will be harvested by future generations and hope i make the
00:15:06right
00:15:06decisions.
00:15:11if the decision is wrong, i have to make expensive changes, rebuild and basically
00:15:15start all over again. to create the forest the
00:15:19future you first need a lot of information about its current
00:15:22condition. a research team. University of Applied
00:15:26Sciences in central Germany is developing an app that allows
00:15:29anyone walking in the woods to share their
00:15:31observations.
00:15:37smartphone horizontally, and then you take three
00:15:40photos. first,
00:15:42it says here, take a picture angled up into the tree
00:15:44canopy, then it tells me to take a second photo straight
00:15:48ahead into the forest, and a third one angled down towards the
00:15:52ground. after that, i can share my location and upload
00:15:56the images. photos taken by forest visitors are
00:16:00a real treasure trobe of data, say the researchers
00:16:02every measurement,
00:16:06every piece. information helps, they've discovered a
00:16:10medium-sized fallen deadwood log, heavily decomposed,
00:16:14even that will be recorded, the data is meant to
00:16:18provide the foundation for a completely new
00:16:20approach. we developing an AI
00:16:24model and investigating whether AI can assess the condition of a forest
00:16:28based on photographs. what
00:16:31special is that anyone can take part? as citizen
00:16:35scientists, volunteers the app to take photos on their
00:16:39walks. The project is called
00:16:43Minervalt Kai, meaning My Forest
00:16:45AI. The
00:16:49researchers trained the AI model behind the app, using more than
00:16:526,00 their own photos from two
00:16:55forests. The next step is to
00:16:59encourage enough citizen scientists to take
00:17:01part. The first version the free
00:17:05myforest AI app is already available. for android. It should
00:17:09provide invaluable insights about the forest's current
00:17:12conditions, but many forest owners need to make changes
00:17:15now, like here in Munich. They need to know which tree species can
00:17:19best withstand heat, drought, and pests, and these are big
00:17:23decisions. Replacing the ecological benefits of a single mature
00:17:26tree, like water storage and carbon capture, can require up to
00:17:30400 young trees a cost of up to €25,00 euros per
00:17:34hectare, and they're having to make these decisions.
00:18:07dedicated forester. That's why he founded a startup called
00:18:11Arbero. Using software and AI, he calculates which
00:18:15tree species can best survive in specific locations. To do
00:18:18that, he purchases data, including from the European space
00:18:22agency. The app
00:18:25combines factors from a wide range of data: how
00:18:29acidic is the soil, is location expected to receive lot
00:18:33of rainfall or very little. How much
00:18:37sun? shine and frost is there, how are temperatures
00:18:41changing, and is the terrain flat or
00:18:44mountainous? all of this is mapped with precision down to just
00:18:47few square meters, using data from the year 2000 up to
00:18:51now. die plattform, the the
00:18:54platform shows existing
00:18:54which tree species is most suitable, both today and in
00:18:58projections extending to the year 20100. i can also
00:19:02change the mix of tree species and see exactly which ones are best suited to
00:19:06that location. Today Sylvius is
00:19:10inspecting bark beetle damage with forester Thomas Venger whose
00:19:14experience helped with the development of our barrow.
00:19:17After the outbreak, many beetle infested trees had to be felled and removed,
00:19:21leaving large stretches almost empty of
00:19:24trees. The
00:19:27losses were substantial. In the future, the digital forester he
00:19:31created will hopefully reduce that risk, but these
00:19:35AI supported systems won't make
00:20:08Experts envision something like this: uniform
00:20:11monocultures such as spruce forests will be replaced by mixed
00:20:15forests made up of deciduous and canniferous trees of different ages
00:20:19and heights. This creates distinct forest layers: the
00:20:22canopy, middle layer and undergrowth; light and shade alternate
00:20:26across the forest floor, encouraging different layers of growth.
00:20:30Sustainability will also play a role. Only individual trees will
00:20:34be removed, a process known as group selection harvesting.
00:20:39the gaps allow the forest to regenerate without losing its cool,
00:20:43moist
00:20:43microclimate. it
00:20:47starts with a single decision, which tree and where? Which species am I
00:20:51putting my faith? It's difficult, but we have access to
00:20:55huge amount of data and we should make use of
00:20:57it. In the future,
00:21:01data will also come from citizen scientists, and everyone who
00:21:05contributes gets a little something in
00:21:07return.
00:21:14When someone uploads a contribution, they receive a thank you message, because we're
00:21:17grateful for every submission from the public. They also
00:21:21receive some information about the forests information.
00:21:25Building the forest the future means making decisions today that will affect
00:21:29generations to come. No one knows exactly what these forests
00:21:33will look like a hundred years, but the process of creating them
00:21:37has already
00:21:37begun.
00:21:47allows people who are deaf or hard of hearing. to feel
00:21:51music through their entire body and get out on the dance
00:21:54floor. now everyone's picking up good
00:21:57vibrations.
00:22:04young musicians are competing for recognition, prestige and
00:22:08prize money in one of Switzerland's biggest talent contests.
00:22:12the crowd is feeling the music, especially the people standing on these
00:22:16special platforms. they convert sound into vibrations.
00:22:20sending it directly through the
00:22:21body that makes the
00:22:25concerts a tangible experience even for people with hearing
00:22:29impairments.
00:22:33it makes a huge difference. when i go to a party, i
00:22:37can feel vibrations through my body, but i don't pick up the finer
00:22:41nuances the music. here with this platform, they really come
00:22:45through. wow, wow,
00:22:48incredible. This is the first time I've experienced anything like
00:22:52this, the platform, the music, it's
00:22:54fantastic. I want more of
00:22:58it, much more, a thousand times
00:23:01more. It's amazing. They should keep
00:23:04doing this.
00:23:08Until now, sign language interpreters could only convey song, lyrics and the
00:23:12mood the music. Now deaf concert goers are
00:23:16getting much more immersive, sensory experience.
00:23:20the vibration platform is being used at concerts for the first time and
00:23:24still requires close supervision from its
00:23:26inventorland.
00:23:32this is a live concert, not pre-recorded music. as soon as the
00:23:36band gets on stage, you have to be ready to make adjustments and bring out the
00:23:40frequencies that are best felt through the
00:23:42body.
00:23:46event technology specialist roland developed the platform largely from home.
00:23:53large coil that creates
00:23:55a
00:24:10This is the tactile transducer, inside there's
00:24:12a magnetic field from the signal we send to
00:24:14it.
00:24:23The vibration platform came about during preparations for the Eurovision
00:24:26song contest in Basel. Roland was part the
00:24:30communications team at Swiss Public Broadcaster
00:24:33SRG. The moto
00:24:37was united by music and we really wanted to embody that
00:24:40idea. The goal was to bring as many people together as
00:24:44possible, including those can't hear music and let them
00:24:47experience it.
00:25:20is connected to music, why should anyone be left
00:25:22out? as deaf community, we're often
00:25:26left out, a concert without a vibration platform isn't nearly as
00:25:30engaging, here we can take part on equal
00:25:32terms. the goal is to
00:25:36make live music more accessible and more inclusive so that more
00:25:40people can enjoy it together, sharing that extra
00:25:43buzz.
