0:00:00.895,0:00:02.543
TED is 30.

0:00:02.543,0:00:05.181
The world wide web is celebrating this month

0:00:05.181,0:00:07.453
its 25th anniversary.

0:00:07.453,0:00:10.142
So I've got a question for you.

0:00:10.142,0:00:14.966
Let's talk about the journey, mainly about the future.

0:00:14.966,0:00:16.681
Let's talk about the state.

0:00:16.681,0:00:18.995
Let's talk about what sort of a web we want.

0:00:18.995,0:00:22.315
So 25 years ago, then, I was working at CERN.

0:00:22.315,0:00:24.665
I got permission in the end after about a year

0:00:24.665,0:00:27.297
to basically do it as a side project.

0:00:27.297,0:00:28.995
I wrote the code.

0:00:28.995,0:00:31.144
I was I suppose the first user.

0:00:31.144,0:00:33.687
There was a lot of concern

0:00:33.687,0:00:35.206
that people didn't want to pick it up

0:00:35.206,0:00:37.030
because it would be too complicated.

0:00:37.030,0:00:38.749
A lot of persuasion, a lot of wonderful

0:00:38.749,0:00:40.459
collaboration with other people,

0:00:40.459,0:00:42.888
and bit by bit, it worked.

0:00:42.888,0:00:44.531
It took off. It was pretty cool.

0:00:44.531,0:00:47.748
And in fact, a few years later in 2000,

0:00:47.748,0:00:51.950
five percent of the world population

0:00:51.950,0:00:53.769
were using the world wide web.

0:00:53.769,0:00:56.480
In 2007, seven years later, 17 percent.

0:00:56.480,0:00:59.820
In 2008, we formed the World Wide Web Foundation

0:00:59.820,0:01:01.394
partly to look at that

0:01:01.394,0:01:04.244
and worry about that figure.

0:01:04.244,0:01:06.303
And now here we are in 2014,

0:01:06.303,0:01:08.537
and 40 percent of the world

0:01:08.537,0:01:12.553
are using the world wide web, and counting.

0:01:12.553,0:01:14.555
Obviously it's increasing.

0:01:14.555,0:01:17.963
I want you to think about both sides of that.

0:01:17.963,0:01:20.180
Okay, obviously to anybody here at TED,

0:01:20.180,0:01:23.163
the first question you ask is, what can we do

0:01:23.163,0:01:25.219
to get the other 60 percent on board

0:01:25.219,0:01:26.539
as quickly as possible?

0:01:26.539,0:01:28.854
Lots of important things. Obviously[br]it's going to be around mobile.

0:01:28.854,0:01:30.834
But also, I want you to think about the 40 percent,

0:01:30.834,0:01:32.544
because if you're sitting there yourself

0:01:32.544,0:01:35.170
sort of with a web-enabled life,

0:01:35.170,0:01:36.466
you don't remember things anymore,

0:01:36.466,0:01:38.180
you just look them up,

0:01:38.180,0:01:42.263
then you may feel that it's been a success

0:01:42.263,0:01:44.243
and we can all sit back.

0:01:44.243,0:01:47.326
But in fact, yeah, it's been a success,

0:01:47.326,0:01:49.272
there's lots of things, Khan Academy

0:01:49.272,0:01:51.561
for crying out loud, there's Wikipedia,

0:01:51.561,0:01:53.378
there's a huge number of free e-books

0:01:53.378,0:01:54.784
that you can read online,

0:01:54.784,0:01:56.552
lots of wonderful things for education,

0:01:56.552,0:01:58.276
things in many areas.

0:01:58.276,0:02:00.678
Online commerce has in some cases

0:02:00.678,0:02:03.469
completely turned upside down the[br]way commerce works altogether,

0:02:03.469,0:02:05.024
made types of commerce available

0:02:05.024,0:02:07.350
which weren't available at all before.

0:02:07.350,0:02:10.732
Commerce has been almost universally affected.

0:02:10.732,0:02:12.999
Government, not universally affected,

0:02:12.999,0:02:15.112
but very affected, and on a good day,

0:02:15.112,0:02:18.080
lots of open data, lots of e-government,

0:02:18.080,0:02:20.783
so lots of things which are visible

0:02:20.783,0:02:22.411
happening on the web.

0:02:22.411,0:02:24.522
Also, lots of things which are less visible.

0:02:24.522,0:02:26.925
The healthcare, late at night when they're worried

0:02:26.925,0:02:28.636
about what sort of cancer

0:02:28.636,0:02:30.761
somebody they care about might have,

0:02:30.761,0:02:35.767
when they just talk across the Internet to somebody

0:02:35.767,0:02:40.276
who they care about very much in another country.

0:02:40.276,0:02:44.495
Those sorts of things are not, they're not out there,

0:02:44.495,0:02:47.715
and in fact they've acquired[br]a certain amount of privacy.

0:02:47.715,0:02:50.499
So we cannot assume that part of the web,

0:02:50.499,0:02:51.590
part of the deal with the web,

0:02:51.590,0:02:53.026
is when I use the web,

0:02:53.026,0:02:56.416
it's just a transparent, neutral medium.

0:02:56.416,0:02:58.952
I can talk to you over it without worrying

0:02:58.952,0:03:01.811
about what we in fact now know is happening,

0:03:01.811,0:03:04.261
without worrying about the fact

0:03:04.261,0:03:06.207
that not only will surveillance be happening

0:03:06.207,0:03:09.245
but it'll be done by people who may abuse the data.

0:03:09.245,0:03:10.451
So in fact, something we realized,

0:03:10.451,0:03:11.860
we can't just use the web,

0:03:11.860,0:03:13.545
we have to worry about

0:03:13.545,0:03:17.119
what the underlying infrastructure of the whole thing,

0:03:17.119,0:03:21.315
is it in fact of a quality that we need?

0:03:21.315,0:03:26.264
We revel in the fact that we[br]have this wonderful free speech.

0:03:26.264,0:03:29.302
We can tweet, and oh, lots and lots of people

0:03:29.302,0:03:32.227
can see our tweets, except when they can't,

0:03:32.227,0:03:35.578
except when actually Twitter[br]is blocked from their country,

0:03:35.578,0:03:38.921
or in some way the way we try to express ourselves

0:03:38.921,0:03:41.856
has put some information[br]about the state of ourselves,

0:03:41.856,0:03:43.219
the state of the country we live in,

0:03:43.219,0:03:45.703
which isn't available to anybody else.

0:03:45.703,0:03:48.684
So we must protest and make sure

0:03:48.684,0:03:50.808
that censorship is cut down,

0:03:50.808,0:03:52.382
that the web is opened up

0:03:52.382,0:03:54.839
where there is censorship.

0:03:54.839,0:03:57.549
We love the fact that the web is open.

0:03:57.549,0:03:59.754
It allows us to talk. Anybody can talk to anybody.

0:03:59.754,0:04:01.592
It doesn't matter who we are.

0:04:01.592,0:04:02.929
And then we join these big

0:04:02.929,0:04:05.582
social networking companies

0:04:05.582,0:04:08.944
which are in fact effectively built as silos,

0:04:08.944,0:04:10.733
so that it's much easier to talk to somebody

0:04:10.733,0:04:12.567
in the same social network

0:04:12.567,0:04:14.890
than it is to talk to somebody in a different one,

0:04:14.890,0:04:19.264
so in fact we're sometimes limiting ourselves.

0:04:19.264,0:04:22.190
And we also have, if you've read[br]the book about the filter bubble,

0:04:22.190,0:04:24.158
the filter bubble phenomenon is that

0:04:24.158,0:04:25.960
we love to use machines

0:04:25.960,0:04:28.092
which help us find stuff we like.

0:04:28.092,0:04:30.434
So we love it when we're bathed in

0:04:30.434,0:04:32.166
what things we like to click on,

0:04:32.166,0:04:34.326
and so the machine automatically feeds us

0:04:34.326,0:04:35.810
the stuff that we like and we end up

0:04:35.810,0:04:40.071
with this rose-colored spectacles view of the world

0:04:40.071,0:04:42.260
called a filter bubble.

0:04:42.260,0:04:44.203
So here are some of the things which maybe

0:04:44.203,0:04:47.295
threaten the social web we have.

0:04:47.295,0:04:49.224
What sort of web do you want?

0:04:49.224,0:04:52.662
I want one which is not[br]fragmented into lots of pieces,

0:04:52.662,0:04:54.845
as some countries have been suggesting

0:04:54.845,0:04:57.945
they should do in reaction to recent surveillance.

0:04:57.945,0:05:01.628
I want a web which has got, for example,

0:05:01.628,0:05:04.588
is a really good basis for democracy.

0:05:04.588,0:05:09.165
I want a web where I can use healthcare

0:05:09.165,0:05:10.920
with privacy and where there's a lot

0:05:10.920,0:05:13.090
of health data, clinical data is available

0:05:13.090,0:05:15.020
to scientists to do research.

0:05:15.020,0:05:18.710
I want a web where the other 60 percent

0:05:18.710,0:05:21.050
get on board as fast as possible.

0:05:21.050,0:05:25.668
I want a web which is such[br]a powerful basis for innovation

0:05:25.668,0:05:27.051
that when something nasty happens,

0:05:27.051,0:05:29.380
some disaster strikes, that we can respond

0:05:29.380,0:05:33.160
by building stuff to respond to it very quickly.

0:05:33.160,0:05:36.090
So this is just some of the things that I want,

0:05:36.090,0:05:38.526
from a big list, obviously it's longer.

0:05:38.526,0:05:39.767
You have your list.

0:05:39.767,0:05:42.541
I want us to use this 25th anniversary

0:05:42.541,0:05:45.534
to think about what sort of a web we want.

0:05:45.534,0:05:47.233
You can go to webat25.org

0:05:47.233,0:05:48.236
and find some links.

0:05:48.236,0:05:49.292
There are lots of sites where people

0:05:49.292,0:05:52.004
have started to put together a Magna Carta,

0:05:52.004,0:05:53.530
a bill of rights for the web.

0:05:53.530,0:05:55.043
How about we do that?

0:05:55.043,0:05:59.670
How about we decide, these are, in a way,

0:05:59.670,0:06:03.330
becoming fundamental rights, the right[br]to communicate with whom I want.

0:06:03.330,0:06:05.288
What would be on your list for that Magna Carta?

0:06:05.288,0:06:08.156
Let's crowdsource a Magna Carta

0:06:08.156,0:06:10.398
for the web.

0:06:10.398,0:06:12.490
Let's do that this year.

0:06:12.490,0:06:15.797
Let's use the energy from the 25th anniversary

0:06:15.797,0:06:18.409
to crowdsource a Magna Carta

0:06:18.409,0:06:19.891
to the web. (Applause)

0:06:19.891,0:06:24.397
Thank you. And do me a favor, will you?

0:06:24.397,0:06:26.963
Fight for it for me. Okay? Thanks.

0:06:26.963,0:06:30.950
(Applause)
