1
00:00:20,720 --> 00:00:24,656
Code is the next universal language.

2
00:00:24,680 --> 00:00:28,856
In the seventies, it was punk music
that drove the whole generation.

3
00:00:28,880 --> 00:00:31,336
In the eighties, it was probably money.

4
00:00:31,360 --> 00:00:33,696
But for my generation of people,

5
00:00:33,720 --> 00:00:38,536
software is the interface
to our imagination and our world.

6
00:00:38,560 --> 00:00:40,256
And that means that we need

7
00:00:40,280 --> 00:00:43,536
a radically, radically
more diverse set of people

8
00:00:43,560 --> 00:00:45,336
to build those products,

9
00:00:45,360 --> 00:00:50,296
to not see computers as mechanical
and lonely and boring and magic,

10
00:00:50,320 --> 00:00:52,296
to see them as things
that they can tinker

11
00:00:52,320 --> 00:00:54,760
and turn around and twist,
and so forth.

12
00:00:55,720 --> 00:00:59,496
My personal journey into the world
of programming and technology

13
00:00:59,520 --> 00:01:02,496
started at the tender age of 14.

14
00:01:02,520 --> 00:01:06,616
I had this mad teenage crush
on an older man,

15
00:01:06,640 --> 00:01:08,976
and the older man in question
just happened to be

16
00:01:09,000 --> 00:01:13,416
the then Vice President
of the United States, Mr. Al Gore.

17
00:01:13,440 --> 00:01:16,496
And I did what every single
teenage girl would want to do.

18
00:01:16,520 --> 00:01:18,736
I wanted to somehow
express all of this love,

19
00:01:18,760 --> 00:01:21,336
so I built him a website, it's over here.

20
00:01:21,360 --> 00:01:24,296
And in 2001, there was no Tumblr,

21
00:01:24,319 --> 00:01:26,576
there was no Facebook,
there was no Pinterest.

22
00:01:26,600 --> 00:01:28,736
So I needed to learn to code

23
00:01:28,760 --> 00:01:32,136
in order to express
all of this longing and loving.

24
00:01:32,160 --> 00:01:34,496
And that is how programming
started for me.

25
00:01:34,520 --> 00:01:37,056
It started as a means of self-expression.

26
00:01:37,080 --> 00:01:40,696
Just like when I was smaller,
I would use crayons and legos.

27
00:01:40,720 --> 00:01:45,320
And when I was older, I would use
guitar lessons and theater plays.

28
00:01:45,920 --> 00:01:48,896
But then, there were other things
to get excited about,

29
00:01:48,920 --> 00:01:51,336
like poetry and knitting socks

30
00:01:51,360 --> 00:01:54,656
and conjugating French irregular verbs

31
00:01:54,680 --> 00:01:56,536
and coming up with make-believe worlds

32
00:01:56,560 --> 00:01:59,696
and Bertrand Russell and his philosophy.

33
00:01:59,720 --> 00:02:01,616
And I started to be one of those people

34
00:02:01,640 --> 00:02:05,320
who felt that computers
are boring and technical and lonely.

35
00:02:06,120 --> 00:02:07,936
Here's what I think today.

36
00:02:07,960 --> 00:02:12,016
Little girls don't know that they
are not supposed to like computers.

37
00:02:12,040 --> 00:02:13,296
Little girls are amazing.

38
00:02:13,320 --> 00:02:17,456
They are really, really good
at concentrating on things

39
00:02:17,480 --> 00:02:20,736
and being exact and they ask
amazing questions like,

40
00:02:20,760 --> 00:02:23,336
"What?" and "Why?"
and "How?" and "What if?"

41
00:02:23,360 --> 00:02:27,040
And they don't know that they
are not supposed to like computers.

42
00:02:27,760 --> 00:02:29,696
It's the parents who do.

43
00:02:29,720 --> 00:02:31,015
It's us parents who feel

44
00:02:31,039 --> 00:02:36,136
like computer science
is this esoteric, weird science discipline

45
00:02:36,160 --> 00:02:39,816
that only belongs to the mystery makers.

46
00:02:39,840 --> 00:02:42,576
That it's almost as far removed
from everyday life

47
00:02:42,600 --> 00:02:45,136
as, say, nuclear physics.

48
00:02:45,160 --> 00:02:47,616
And they are partly right about that.

49
00:02:47,640 --> 00:02:51,136
There's a lot of syntax
and controls and data structures

50
00:02:51,160 --> 00:02:53,816
and algorithms and practices,

51
00:02:53,840 --> 00:02:56,416
protocols and paradigms in programming.

52
00:02:56,440 --> 00:03:00,736
And we as a community,
we've made computers smaller and smaller.

53
00:03:00,760 --> 00:03:05,296
We've built layers and layers
of abstraction on top of each other

54
00:03:05,320 --> 00:03:06,816
between the man and the machine

55
00:03:06,840 --> 00:03:10,056
to the point that we no longer
have any idea how computers work

56
00:03:10,080 --> 00:03:12,256
or how to talk to them.

57
00:03:12,280 --> 00:03:15,056
And we do teach our kids
how the human body works,

58
00:03:15,080 --> 00:03:18,176
we teach them how
the combustion engine functions

59
00:03:18,200 --> 00:03:21,216
and we even tell them
that if you want to really be an astronaut

60
00:03:21,240 --> 00:03:22,696
you can become one.

61
00:03:22,720 --> 00:03:24,896
But when the kid comes to us and asks,

62
00:03:24,920 --> 00:03:27,656
"So, what is a bubble sort algorithm?"

63
00:03:27,680 --> 00:03:32,096
Or, "How does the computer know
what happens when I press 'play,'

64
00:03:32,120 --> 00:03:33,976
how does it know which video to show?"

65
00:03:34,000 --> 00:03:36,576
Or, "Linda, is Internet a place?"

66
00:03:36,600 --> 00:03:39,320
We adults, we grow oddly silent.

67
00:03:40,400 --> 00:03:42,856
"It's magic," some of us say.

68
00:03:42,880 --> 00:03:45,600
'It's too complicated," the others say.

69
00:03:46,520 --> 00:03:48,016
Well, it's neither.

70
00:03:48,040 --> 00:03:50,616
It's not magic and it's not complicated.

71
00:03:50,640 --> 00:03:54,256
It all just happened
really, really, really fast.

72
00:03:54,280 --> 00:03:57,176
Computer scientists built
these amazing, beautiful machines,

73
00:03:57,200 --> 00:03:59,616
but they made them
very, very foreign to us,

74
00:03:59,640 --> 00:04:01,856
and also the language we speak
to the computers

75
00:04:01,880 --> 00:04:04,896
so that we don't know
how to speak to the computers anymore

76
00:04:04,920 --> 00:04:07,416
without our fancy user interfaces.

77
00:04:07,440 --> 00:04:09,016
And that's why no one recognized

78
00:04:09,040 --> 00:04:11,736
that when I was conjugating
French irregular verbs,

79
00:04:11,760 --> 00:04:15,016
I was actually practicing
my pattern recognition skills.

80
00:04:15,040 --> 00:04:17,336
And when I was excited about knitting,

81
00:04:17,360 --> 00:04:20,896
I actually was following
a sequence of symbolic commands

82
00:04:20,920 --> 00:04:22,656
that included loops inside of them.

83
00:04:22,680 --> 00:04:25,096
And that Bertrand Russell's lifelong quest

84
00:04:25,120 --> 00:04:29,096
to find an exact language
between English and mathematics

85
00:04:29,120 --> 00:04:31,440
found its home inside of a computer.

86
00:04:32,080 --> 00:04:34,280
I was a programmer, but no one knew it.

87
00:04:35,080 --> 00:04:39,536
The kids of today, they tap, swipe
and pinch their way through the world.

88
00:04:39,560 --> 00:04:42,776
But unless we give them tools
to build with computers,

89
00:04:42,800 --> 00:04:46,736
we are raising only consumers
instead of creators.

90
00:04:46,760 --> 00:04:49,296
This whole quest
led me to this little girl.

91
00:04:49,320 --> 00:04:51,696
Her name is Ruby, she is six years old.

92
00:04:51,720 --> 00:04:55,816
She is completely fearless,
imaginative and a little bit bossy.

93
00:04:55,840 --> 00:04:58,296
And every time
I would run into a problem

94
00:04:58,320 --> 00:05:00,576
in trying to teach
myself programming like,

95
00:05:00,600 --> 00:05:04,576
"What is object-oriented design
or what is garbage collection?",

96
00:05:04,600 --> 00:05:09,016
I would try to imagine how a six-year-old
little girl would explain the problem.

97
00:05:09,040 --> 00:05:11,696
And I wrote a book about her
and I illustrated it

98
00:05:11,720 --> 00:05:14,096
and the things
Ruby taught me go like this.

99
00:05:14,120 --> 00:05:16,576
Ruby taught me that you're
not supposed to be afraid

100
00:05:16,600 --> 00:05:17,976
of the bugs under your bed.

101
00:05:18,000 --> 00:05:20,056
And even the biggest of the problems

102
00:05:20,080 --> 00:05:23,576
are a group of tiny problems
stuck together.

103
00:05:23,600 --> 00:05:26,336
And Ruby also introduced
me to her friends,

104
00:05:26,360 --> 00:05:29,256
the colorful side of the Internet culture.

105
00:05:29,280 --> 00:05:31,136
She has friends like the Snow Leopard,

106
00:05:31,160 --> 00:05:34,096
who is beautiful but doesn't want
to play with the other kids.

107
00:05:34,120 --> 00:05:38,736
And she has friends like the green robots
that are really friendly but super messy.

108
00:05:38,760 --> 00:05:40,936
And she has friends like Linux the penguin

109
00:05:40,960 --> 00:05:44,616
who's really ruthlessly efficient,
but somewhat hard to understand.

110
00:05:44,640 --> 00:05:46,880
And idealistic foxes, and so on.

111
00:05:47,880 --> 00:05:51,536
In Ruby's world, you learn
technology through play.

112
00:05:51,560 --> 00:05:54,776
And, for instance, computers
are really good at repeating stuff,

113
00:05:54,800 --> 00:05:57,696
so the way Ruby would teach
loops goes like this.

114
00:05:57,720 --> 00:06:01,096
This is Ruby's favorite dance move,
it goes, "Clap, clap, stomp, stomp

115
00:06:01,120 --> 00:06:02,616
clap, clap and jump."

116
00:06:02,640 --> 00:06:06,656
And you learn counter loops
by repeating that four times.

117
00:06:06,680 --> 00:06:09,496
And you learn while loops
by repeating that sequence

118
00:06:09,520 --> 00:06:11,296
while I'm standing on one leg.

119
00:06:11,320 --> 00:06:14,616
And you learn until loops
by repeating that sequence

120
00:06:14,640 --> 00:06:16,696
until mom gets really mad.

121
00:06:16,720 --> 00:06:17,736
(Laughter)

122
00:06:17,760 --> 00:06:21,480
And most of all, you learn
that there are no ready answers.

123
00:06:22,320 --> 00:06:25,056
When coming up with the curriculum
for Ruby's world,

124
00:06:25,080 --> 00:06:28,376
I needed to really ask the kids
how they see the world

125
00:06:28,400 --> 00:06:30,416
and what kind of questions they have

126
00:06:30,440 --> 00:06:32,520
and I would organize
play testing sessions.

127
00:06:33,360 --> 00:06:35,920
I would start by showing the kids
these four pictures.

128
00:06:36,480 --> 00:06:38,816
I would show them a picture of a car,

129
00:06:38,840 --> 00:06:41,256
a grocery store, a dog and a toilet.

130
00:06:41,280 --> 00:06:44,520
And I would ask, "Which one of these
do you think is a computer?"

131
00:06:45,480 --> 00:06:48,216
And the kids would be
very conservative and go,

132
00:06:48,240 --> 00:06:50,016
"None of these is a computer.

133
00:06:50,040 --> 00:06:51,696
I know what a computer is:

134
00:06:51,720 --> 00:06:53,056
it's that glowing box

135
00:06:53,080 --> 00:06:56,696
in front of which mom or dad
spends way too much time."

136
00:06:56,720 --> 00:06:58,216
But then we would talk

137
00:06:58,240 --> 00:07:01,056
and we would discover
that actually, a car is a computer,

138
00:07:01,080 --> 00:07:03,456
it has a navigation system inside of it.

139
00:07:03,480 --> 00:07:06,256
And a dog -- a dog
might not be a computer,

140
00:07:06,280 --> 00:07:07,496
but it has a collar

141
00:07:07,520 --> 00:07:10,136
and the collar might have
a computer inside of it.

142
00:07:10,160 --> 00:07:13,616
And grocery stores, they have
so many different kinds of computers,

143
00:07:13,640 --> 00:07:17,056
like the cashier system
and the burglar alarms.

144
00:07:17,080 --> 00:07:18,416
And kids, you know what?

145
00:07:18,440 --> 00:07:20,976
In Japan, toilets are computers

146
00:07:21,000 --> 00:07:22,896
and there's even hackers who hack them.

147
00:07:22,920 --> 00:07:24,696
(Laughter)

148
00:07:24,720 --> 00:07:25,936
And we go further

149
00:07:25,960 --> 00:07:29,176
and I give them these little stickers
with an on/off button on them.

150
00:07:29,200 --> 00:07:32,816
And I tell the kids,
"Today you have this magic ability

151
00:07:32,840 --> 00:07:36,456
to make anything in this room
into a computer."

152
00:07:36,480 --> 00:07:37,816
And again, the kids go,

153
00:07:37,840 --> 00:07:40,736
"Sounds really hard,
I don't know the right answer for this."

154
00:07:40,760 --> 00:07:42,336
But I tell them, "Don't worry,

155
00:07:42,360 --> 00:07:44,936
your parents don't know
the right answer, either.

156
00:07:44,960 --> 00:07:47,176
They've just started
to hear about this thing

157
00:07:47,200 --> 00:07:49,416
called The Internet of Things.

158
00:07:49,440 --> 00:07:51,416
But you kids,
you are going to be the ones

159
00:07:51,440 --> 00:07:55,816
who are really going to live up in a world
where everything is a computer."

160
00:07:55,840 --> 00:07:58,056
And then I had this little girl
who came to me

161
00:07:58,080 --> 00:07:59,376
and took a bicycle lamp

162
00:07:59,400 --> 00:08:03,616
and she said, "This bicycle lamp,
if it were a computer,

163
00:08:03,640 --> 00:08:05,656
it would change colors."

164
00:08:05,680 --> 00:08:08,696
And I said, "That's a really good idea,
what else could it do?"

165
00:08:08,720 --> 00:08:10,456
And she thinks and she thinks,

166
00:08:10,480 --> 00:08:14,496
and she goes, "If this bicycle lamp
were a computer,

167
00:08:14,520 --> 00:08:17,256
we could go on a biking trip
with my father

168
00:08:17,280 --> 00:08:18,896
and we would sleep in a tent

169
00:08:18,920 --> 00:08:22,760
and this biking lamp
could also be a movie projector."

170
00:08:23,640 --> 00:08:25,600
And that's the moment I'm looking for,

171
00:08:26,400 --> 00:08:27,976
the moment when the kid realizes

172
00:08:28,000 --> 00:08:30,376
that the world
is definitely not ready yet,

173
00:08:30,400 --> 00:08:33,376
that a really awesome way
of making the world more ready

174
00:08:33,400 --> 00:08:35,616
is by building technology

175
00:08:35,640 --> 00:08:38,400
and that each one of us
can be a part of that change.

176
00:08:39,200 --> 00:08:42,256
Final story, we also built a computer.

177
00:08:42,280 --> 00:08:47,016
And we got to know the bossy CPU
and the helpful RAM and ROM

178
00:08:47,040 --> 00:08:48,456
that help it remember things.

179
00:08:48,480 --> 00:08:51,416
And after we've assembled
our computer together,

180
00:08:51,440 --> 00:08:54,096
we also design an application for it.

181
00:08:54,120 --> 00:08:56,135
And my favorite story is this little boy,

182
00:08:56,159 --> 00:08:57,416
he's six years old

183
00:08:57,440 --> 00:09:00,559
and his favorite thing in the world
is to be an astronaut.

184
00:09:01,120 --> 00:09:03,376
And the boy, he has
these huge headphones on

185
00:09:03,400 --> 00:09:06,656
and he's completely immersed
in his tiny paper computer

186
00:09:06,680 --> 00:09:08,696
because you see, he's built his own

187
00:09:08,720 --> 00:09:13,016
intergalactic planetary
navigation application.

188
00:09:13,040 --> 00:09:16,176
And his father, the lone astronaut
in the Martian orbit,

189
00:09:16,200 --> 00:09:18,056
is on the other side of the room

190
00:09:18,080 --> 00:09:19,696
and the boy's important mission

191
00:09:19,720 --> 00:09:22,640
is to bring the father
safely back to earth.

192
00:09:23,760 --> 00:09:27,216
And these kids are going to have
a profoundly different view of the world

193
00:09:27,240 --> 00:09:29,640
and the way we build it with technology.

194
00:09:30,840 --> 00:09:34,696
Finally, the more approachable,
the more inclusive,

195
00:09:34,720 --> 00:09:38,096
and the more diverse
we make the world of technology,

196
00:09:38,120 --> 00:09:42,096
the more colorful and better
the world will look like.

197
00:09:42,120 --> 00:09:44,696
So, imagine with me, for a moment,

198
00:09:44,720 --> 00:09:47,296
a world where the stories we tell

199
00:09:47,320 --> 00:09:50,336
about how things get made
don't only include

200
00:09:50,360 --> 00:09:52,776
the twentysomething-year-old
Silicon Valley boys,

201
00:09:52,800 --> 00:09:57,200
but also Kenyan schoolgirls
and Norwegian librarians.

202
00:09:58,000 --> 00:10:02,216
Imagine a world where
the little Ada Lovelaces of tomorrow,

203
00:10:02,240 --> 00:10:05,456
who live in a permanent
reality of 1s and 0s,

204
00:10:05,480 --> 00:10:10,096
they grow up to be very optimistic
and brave about technology.

205
00:10:10,120 --> 00:10:13,496
They embrace the powers
and the opportunities

206
00:10:13,520 --> 00:10:15,120
and the limitations of the world.

207
00:10:15,680 --> 00:10:19,816
A world of technology
that is wonderful, whimsical

208
00:10:19,840 --> 00:10:21,480
and a tiny bit weird.

209
00:10:23,120 --> 00:10:24,616
When I was a girl,

210
00:10:24,640 --> 00:10:26,656
I wanted to be a storyteller.

211
00:10:26,680 --> 00:10:28,256
I loved make-believe worlds

212
00:10:28,280 --> 00:10:29,896
and my favorite thing to do

213
00:10:29,920 --> 00:10:33,976
was to wake up in the mornings
in Moominvalley.

214
00:10:34,000 --> 00:10:37,120
In the afternoons,
I would roam around the Tatooines.

215
00:10:37,320 --> 00:10:40,200
And in the evenings,
I would go to sleep in Narnia.

216
00:10:41,400 --> 00:10:44,600
And programming turned out
to be the perfect profession for me.

217
00:10:45,720 --> 00:10:47,656
I still create worlds.

218
00:10:47,680 --> 00:10:50,640
Instead of stories, I do them with code.

219
00:10:51,640 --> 00:10:54,696
Programming gives me this amazing power

220
00:10:54,720 --> 00:10:57,096
to build my whole little universe

221
00:10:57,120 --> 00:11:01,080
with its own rules
and paradigms and practices.

222
00:11:02,120 --> 00:11:06,080
Create something out of nothing
with the pure power of logic.

223
00:11:06,920 --> 00:11:08,136
Thank you.

224
00:11:08,160 --> 00:11:10,600
(Applause)
