This week, wall climbing graffiti bots. All aboard the holodeck. And
just watch out for the rodents. Oh, there is a mouth! -- mouse!
Data is all around us. We generate around 2.5 billion GB of it every
day. Think of it as, well, there is no other word for it, really.
Enormous. And we are finding lots of new ways of gathering even more of
it. Machines are now able to look at videos and interpret what is in the
image, and with the number of CCTV cameras around the town, imagine how
much more data we can collect. But the real intelligence is not in
capturing the data. It is in analysing it. And this is where
artificial intelligence might make a real difference, making connections
that we humans never would. Big data has accelerated our understanding of
medical science in unimaginable ways. It is now influencing how
hospitals treat patients, police forces manage crime, and city
officials run our towns. And it is inevitable, in the next 50 years,
that AI will play an even bigger role in our society, and influence
how we go about living. I recently met DJ Patil, President Barack
Obama's chief data scientist, who was in charge of shaping how big
data is used by the government to make big policy decisions, while
ensuring the AIA created by the tech companies treat everyone fairly and
make good decisions. That is where we have to start focusing more about
energy, is asking the question of how do we actually make sure that
these algorithms are going to work the way we want? People talk about
self driving cars. It is a self driving car going to see someone
with my skin tone, or someone with a darker skin tone? A person with a
wheelchair? Is that a person in the dataset? How do start saying... You
are suggesting whether a self driving car would recognise you as
something it should avoid. Yes, Boyd, because we have different skin
colour. Are people with your skin colour the only ones in the data
set, am I ignored? Is that an accident? But what about somebody
with a handicap? What about a kid on a tricycle? It is not sufficient to
say oops about the algorithm. We have to figure out a more robust
process as these things are becoming more integrated into our society.
And if we have learned anything from this week's Facebook story, it is
that tech companies are not the most transparent lunch. Facebook has been
around for more than a decade, and only now, by chance, have we got a
glimpse of how its moderators decide what we see on its platform. So how
do we make sure the AI built by the same tech companies are using our
data responsibly? So the first, it comes down to how are you trained?
In our training these days, we often have found that technologists are no
longer trained in humanities. One of the most critical components of
humanities is the notion of ethics, so what we have called for is that
every data scientist, every economist, anybody who works with
data, must have ethics integrated throughout their entire curriculum.
So you can start to have the conversation and dialogue about what
are the ethical implications of the choices you make second part of this
is how about security of the data? How do you make sure that you are
actually building the algorithms with security, the datasets with the
purity so people can't just break in. That has to no longer be elected
or something outside. That has to be part of the core training. Once you
have this component of our training, I think you are going to have a new
set of people who have the vocabulary to talk about it. But
that doesn't take into account the speed at which it is happening on
taking place today. So what we do then? Number one, transparency.
President Obama signed an executive order that said by default all data
the Federal Government on the US Federal Government, publishers, must
be open and machine-readable. And what that allows people to do is be
able to access the data, preparing, use it, and innovate with it --
compare it. And that is the problem, how do we strike the balance? We
need to know that a AI system is not biased as loan from a dataset which
includes all of us, and its decisions are fair, but we also
don't want to stifle its process will make progress, because when it
is used in the right way it really can change things for the better.
What we have found in one of the problems around a local jail system
is that there is a huge number of people who are just cycling in and
out of the system. I mean, the numbers are extraordinary. More than
11 million people through 3100 jails, they stay there on average 23
days. 95% never go to long-term prison. It turns out there are a lot
of mental health issues, a lot of drug addiction. So what happens to
those people? Where is the data going? It stays in silos. The
healthcare system has a silo, criminal justice. So what happens if
you just talk and share that information? Is said do you see
Sally and data set and say we saw Sally all the time? Well, why are we
sending her to jail, let's send her to the right intervention. So doing
that, how much can you save? What is the real impact? It costs 1.5
million to train of Ron on the right intervention and share the data, and
everything. The first year alone they saved more than $10 million,
but more importantly they were able to close a full jail. And later on
they close second jail because they are giving people the right care.
It was the week that Volvo announced it's working on an AI rubbish truck

The hope now is it will be used in medicine and science in the future.
More bad news for Uber this week, as it admitted it underpaid drivers
in New York for more than two and a half years.
Tens of thousands of drivers will now be paid about $900 each,
which will mean Uber paying out tens of millions of dollars.
And only one month into the release of Samsung's new Galaxy S8
smartphone virus scanner, and it's already been hacked.
German hackers fooled the scanner with only a paper printer
and a contact lens to make the fake eye.
And is RoboCop from the '80s becoming a reality?
Well, not quite, but Dubai police want these robots to make up 25%
They launched the unit on Wednesday, which can forward video

Graffiti art has been one of the hottest art movements over

In this case, the streets of Bristol.
And he has since grown into the artist that we see on the roof
Today, he's taking a break to do this for us.
But he's more known these days for these amazing natural scenes
which are exhibited and sold all over the world,
and which incorporate all of the graffiti techniques that

No, we don't have that kind of patience.
So could we pull off something similar to this by combining
technology with someone who has no creative talent whatsoever?
To find out, we sent Nick Kwek to Estonia...
Tartu, Estonia's second-largest city.
Like most cities, graffiti and street art provoke
It's also home to one of the biggest spray-painted pieces
But Albert's been painted dot by dot, and I've been promised I too
can achieve artistic genius with the right tools.
Believe it or not, these pictures have all been
They've been pieced together splodge by splodge
My daughter wanted a unicorn on her wall, but I couldn't draw.
So that pushed me towards creating this device.
To make these magical masterpieces you need the right kit -
a smartphone with the appropriate app installed, an external battery
pack to keep it fully juiced, a tripod to hold it steady,
some paint, and of course the SprayPrinter.
First you select an image and align it against
So the image is projected like a giant virtual sticker.
The phone's camera exposes for the LED on the device,
and when it illuminates it sends the can's location to the app.
The phone then tells the printer its coordinates
and the printer decides when to spray and when not to.
Once you get the knack of it, it's actually surprisingly simple to use.
You just have to make sure you go from left to right, or right to
left, very smoothly, in a straight line.
For all its geeky brilliance, it's a real labour of love.
Even the most simple of designs takes several

I developed this extra accessory for the SprayPrinter to
atomise the process, because for high scale
images the hand-held method takes too much time and
too, hopefully speeding things up a bit.
But does the printer help artistic expression, or
gives like guidelines of how to paint.
It's like sort of a colouring book, but

It started off only a few small dots.
You actually have to stand back a few feet to get the
full view, to get the right perspective on it.
So what would you like to see spray-painted next?
Well, the guys have been holding a competition
and this winning submission, just announced, will soon be painted on
a local giant abandoned power station
chimney for all to see, but painting on this
curved structure has posed new
problems, which Mihkel is determined to solve.

It definitely has its advantages, for
Well, in the meantime, this is beautiful.
Thanks so much for doing this for us.
We're going to stay on and art tip now.
Here at Photo London art takes many forms.
But the thing I've seen that I've grappled with the
most is the idea of a virtual reality gallery.
Is this really a way to fully experience art?
So what's going on in here, and in here?
Well, in the 1800s when people saw photography for the first time they
were absolutely wowed by it, but of course now
So what's happening is some of those initial images are being
brought back to life in virtual reality.
original original photographic images were shown has been recreated
Well, initially I wasn't sure that looking at these images in
virtual reality seemed like something that actually makes
sense, but apparently you can pick up the
images by holding your hand over it like that,
and then you can hold the image in your hand...
You can really see the texture of it as well.
This genuinely feels like I'm standing in
In fact, it actually feels quite hazardous
because you can see smoke coming off it and that is proper serious heat.
But whilst the juxtaposition between the origins of photography
and a new visual medium are deliberate, making sure it
provides a meaningful experience for those with a yearning for art
Nothing fills me with a greater melancholy than going
into an exhibition and seeing somebody with a virtual reality
headset on, and having to queue and wait for your turn on it -
So what I've tried to do in this installation is to make that part
of the actual experience, so when you're not in the room
you can look at people with their headsets
Watching the goings-on of people wandering around is quite strange
and surreal to look at, so hopefully it's still interesting
as an artwork even when you're not in the headset.
So I can hear some sound coming from over here.
That's because of the binaural sound that's built in,
and there seems to be something happening outside...
I believe this is the Chartists' revolt.
This is a lot of people objecting to photography.
This wasn't the only VR at the show, though.
One family of art collectors wanted to virtually take
You can have your art museum in your pocket.
I can have 200 metre museum just in my laptop.
That could be sharing a collection internationally, a trip to a
virtual art gallery for those who are housebound, or
introducing a new audience to art who might be more
The real-life version of this statue is
I will head towards it and have a closer look.
I can actually see the size of it by those
And in fact the size of that piece of art behind
it, the scale of all of this, is absolutely massive.
It would require such a large building to actually
Amidst the physical art were the latest
imaging, entire film is superimposed on
single images, and this Paris park scene.
So behind this photograph we are looking at here is actually a
massive plate of LED lights, all spread out with an inch between
them, so each time you can see a person crossing the screen it's
actually a combination of these lights being dimmed in that pattern,
and what the human eye fills an in between to make it
One thing that seemed clear by the end of the day,
though, was that VR can feel a natural part of an art show, and
that I'm never going to be an art expert.

this week Mark Cieslak became the captain of a starship!
He took some of the rest of the Click family
with him, to boldly go where no Mark has gone before.
These are the virtual voyages of the BBC Click
Our mission: To wear VR headsets and discover strange, new
technology, and boldly go where no TV reporter has gone before.
Virtual reality game Star Trek Bridge Crew
brings together up to four players, each

The beauty of going where no one has gone before
is that starship travel involves an awful lot of sitting down.
Sitting down is great for virtual reality
because the headsets have got these cables.
If you're moving around it easy to get caught up with them.
And where better to be sitting in the
Captain's chair of a Federation starship?
Headsets on, it's time for the Click team to become a starship
The early missions are all about orientating us with the bridge
As helmsman, you are the ship's navigator.
The headset shows us what the bridge looks like, but the
PlayStation motion controllers allow us to interact with the various
controls we have to master in order to fly the ship.
We don't have time for sight seeing, though, as we receive
a distress signal from a stricken vessel.
My vessel has lost all power and our life-support systems are

It's at this moment that the action takes
a turn which will appeal to Star Trek superfans.
OK, guys, this is the Kobayashi Maru scenario.
This is an impossible to win situation.

Line up the phasers, and torpedoes away.
Yeah, everybody, we just violated a peace treaty.
It's pretty warm work being in virtual reality.
It feels like it's social VR at its best, really.
If you don't have it you're not going to complete the mission.
I thought we actually had our lives on the
That ably demonstrates the power of teamwork.
It's really, really important that everybody plays their role on the
bridge, because if you don't then chaos ensues.
We had a couple of sticky moments there, but I think we
managed to pull it back and keep it together as a crew.
And the result was a successful mission.
