President Jahanian, members of the Board of Trustees,
2
faculty, distinguished guests, proud parents and families,
3
and above all, the Carnegie Mellon Class of 2026!
4
Thank you for this extraordinary honor.
5
It is deeply meaningful to be here with Carnegie Mellon,
6
one of the world's great universities and one of the rare places that invents the future.
7
Today is a day of pride and joy,
8
a dream come true for you but not only for you.
9
Your families, teachers, mentors and friends help carry you here.
10
Before we talk about the future, thank them.
11
This day belongs to them too.
12
Graduates, please stand up.
13
Stand with me.
14
Come on you guys.
15
Especially turn to your mothers and wish them a happy Mother's Day.
16
For you, this is another step in your life.
17
But for her, this is a dream come true.
18
Please sit down.
19
CMU students like robots take instructions one at a time.
20
To see her graduate, to see you.
21
Okay, everybody focus.
22
I have something important to tell you.
23
To see you graduate from one of the world's great institutions,
24
this is her moment too.
25
My mom and dad are deeply proud of me as well.
26
My journey is their journey.
27
I am their dream come true.
28
And their dream was the American dream.
29
Like many in this audience, I'm a first-generation immigrant.
30
Thank you.
31
My father had a dream to raise his family in America.
32
When I was nine years old,
33
he sent my older brother and me to the United States.
34
We ended up at a Baptist boarding school in Oneida, Kentucky.
35
Coal country.
36
A town of a few hundred people.
37
Two years later, my parents left everything behind to join us.
38
They came with little to nothing.
39
My father was a chemical engineer.
40
My mother worked as a maid at a Catholic school.
41
She woke me up at 4 a.m in the morning to deliver newspapers.
42
My older brother got me a job as a dishwasher at Denny's,
43
which at the time felt like a major career advancement.
44
That was my view of America.
45
Not easy, but full of opportunities.
46
Not a guarantee, but a chance.
47
My parents came here because they believed America could give their children a chance.
48
How can we not be romantic about America?
49
I went to Oregon State University.
50
I met my wife, Lori,
51
when I was 17 years old.
52
I was the youngest kid in school.
53
We were sophomore lab partners.
54
She was 19.
55
An older woman.
56
I beat out 250 other boys in class and won her heart.
57
We've now been married for 40 years.
58
We have two amazing children, both working at NVIDIA.
59
When I was 30, I started NVIDIA with Chris Malachowski and Curtis Primm,
60
two amazing computer scientists.
61
We wanted to build a new kind of computer,
62
one that could solve problems ordinary computers could not.
63
We had absolutely no idea how to build a company,
64
raise money, or run NVIDIA.
65
I just thought, how hard could it be?
66
It turns out, it is super hard.
67
Our first technology didn't even work.
68
We ran out of, we nearly ran out of money.
69
At one point, I had to fly to Japan
70
and explain to Sega's CEO that the technology they contracted us to build would not work.
71
Asked to be released from a contract we could not complete.
72
And then asked that they still pay us.
73
Without the money, NVIDIA would vaporize.
74
It was embarrassing, humiliating, and one of the hardest things I have ever done.
75
And Sega CEO, Irmajri San, said yes.
76
I learned early that being CEO is not about power,
77
but the responsibility that comes with keeping the company alive.
78
And that honesty and humility can be met with generosity and kindness, even in business.
79
We used the money to reset the company,
80
and out of desperation we invented new ways of designing chips and computers that we still use today.
81
For 33 years, NVIDIA had reinvented itself over and over again,
82
each time asking, how How hard can it be?
83
And each time learning, it's harder than we thought.
84
But through those experiences, we learn never to see failure as the opposite of success.
85
Each failure is just another learning moment,
86
a humility moment, a character strengthening moment.
87
The resilience forged through setbacks is what gives you the strength to go again.
88
Today, I am one of the longest serving CEOs in technology.
89
NVIDIA, the body of work I share with 45,000 extraordinary colleagues is my life's work.
90
Now it's your time to realize your dreams.
91
And the timing could not be more perfect.
92
My career started at the beginning of the PC revolution.
93
Your career starts at the beginning of the AI revolution.
94
I cannot imagine a more exciting time to work,
95
to begin your life's work.
96
AI started right here at Carnegie Mellon.
97
I've heard countless AI jokes in the last 24 hours here at Carnegie Mellon.
98
Carnegie Mellon is one of the true birthplaces of artificial intelligence and robotics.
99
In the 1950s, researchers here created the logic theorist,
100
widely recognized and considered the first AI computer program.
101
In 1979, Carnegie Mellon founded the Robotics Institute.
102
This morning I visited with Robo Club,
103
the first academic institute devoted entirely to robotics.
104
Artificial intelligence has gone on now to reinvent computing completely.
105
I have lived through every major computing platform shift.
106
mainframes, PCs, the internet, mobile, and cloud.
107
Each wave built on the one before.
108
Each expanded access, each transformed industries and society,
109
but what is about to happen now is bigger than anything before.
110
Computing is undergoing a complete reset,
111
not since modern computing was first invented.
112
For 60 years, computing worked the same way.
113
Humans wrote software, computers executed instructions.
114
That paradigm is over.
115
Artificial intelligence has reinvented computing,
116
from human coding to machine learning,
117
from software running on CPUs to neural networks running on GPUs,
118
and from following instructions to understanding,
119
reasoning, planning, and using tools.
120
A new industry has emerged to manufacture intelligence at scale.
121
Because intelligence is foundational to every industry, every industry will change.
122
For many, AI creates uncertainty.
123
People see AI writing software,
124
generating images, driving cars, and naturally wonder what happens next.
125
Will jobs disappear?
126
Will people be left behind?
127
Will this technology become too powerful?
128
Every major technological revolution in history created fear alongside opportunity.
129
When society engages technology openly,
130
responsibly, and optimistically, we expand human potential.
131
far more than we diminish it.
132
So first and above all, we must be clear-eyed.
133
Artificial intelligence, the automation of understanding,
134
reasoning, and problem solving is one of the most powerful technologies humanity has ever created.
135
And like every transformative technology before it,
136
it will bring both great promise and real risks.
137
The responsibility of our generation is not only to advance AI,
138
but to advance it wisely.
139
Scientists and engineers have a profound responsibility to advance AI capabilities and AI safety together.
140
Policy makers,
141
Policy makers have a responsibility to create thoughtful guardrails that protect society while still allowing innovation,
142
discovery and progress to move forward.
143
History shows that societies that retreat from technology do not stop progress.
144
They only surrender the opportunity to shape it and to benefit from it.
145
So the answer is not to fear the future.
146
The answer is to guide it wisely,
147
build it responsibly, and ensure that it benefits reach as many people as possible.
148
We should not teach fear of the future.
149
We should engage it with optimism, responsibility, and ambition.
150
a fraction of the people in the world know how to write software.
151
Now anyone can ask AI to build something useful.
152
A shopkeeper can create a website and grow a business.
153
A carpenter can design a kitchen and offer new services to clients.
154
The AI writes the code.
155
Everyone is now a programmer.
156
For the first time, the power of computing and intelligence can truly reach everyone and close the technology divide the first time.
157
And like electricity and the internet before it,
158
AI will require trillions of dollars of infrastructure investment.
159
This is the largest technology infrastructure build out in human history and a once in a generation opportunity
160
to re-industrialize America and restore the nation's capacity to build.
161
To support AI, America will build chip factories,
162
computer factories, data centers, and advanced manufacturing facilities across the country.
163
AI gives America the opportunity to build again.
164
Electricians, plumbers, iron workers, technicians,
165
builders, this is your time.
166
AI is not just creating a new computing industry,
167
it is creating a new industrial era.
168
Powering this new infrastructure will require enormous amounts of energy.
169
But it is also driving one of the largest investments in energy infrastructure in generations.
170
the grid, expanding power generation, and accelerating sustainable energy.
171
And yes, AI will change every job.
172
But the task and the purpose of a job are not the same.
173
Many tasks will be automated.
174
Some jobs will disappear.
175
But many new jobs and entire new industries will be created.
176
coding tasks are increasingly automated.
177
But using AI, software engineers can expand the search for solutions,
178
allowing them to tackle far more ambitious challenges.
179
Analyzing radiology scans is increasingly automated.
180
But using AI, radiologists are elevated to better diagnose disease and care for patients.
181
AI does not replace human purpose.
182
It amplifies human capability.
183
That is why even as AI writes more code and analyzes more scans,
184
demand for software engineers and radiologists continue to grow.
185
AI is not likely to replace you.
186
But someone using AI better than you might.
187
So a good thought experiment is this.
188
Do we want our children to be supercharged by AI or be left behind by those who are?
189
No parent wants their child left behind.
190
So So let us build AI safely.
191
Let us also imagine an optimistic future,
192
one our children are excited to be part of, inspired to help build.
193
So we can and must do four things at once.
194
Advance safely, create thoughtful policies,
195
make AI broadly accessible, and encourage everyone to engage.
196
should have AI.
197
Opportunity should not belong only to the people who can code.
198
Class of 2026, you are entering the world at an extraordinary moment.
199
A new industry is being born.
200
A new era of science and discovery is beginning.
201
AI will accelerate the expansion of human knowledge and help solve problems once beyond our reach.
202
We have the opportunity to close the technology divide
203
and bring the power of computing and intelligence to billions of people for the very first time.
204
To re-industrialize America and restore our capacity to build and to help create a future more abundant,
205
more capable, and more hopeful than the world you inherited.
206
No generation has entered the world with more powerful tools or greater opportunities than you.
207
We are all standing at the same starting line.
208
This is your moment to help shape what comes next.
209
So run, don't walk.
210
Carnegie Mellon has a motto I love.
211
My heart is in the work.
212
So put your heart in the work,
213
build something worthy of your education,
214
your potential, and the people who believed in you long before the world did.
215
Congratulations Carnegie Mellon, Class of 2026!
216
Thank you.

このビデオで話す練習をする理由
このビデオは、カーネギーメロン大学の卒業式でのスピーチであり、英語を学ぶ上で非常に価値のあるリソースです。スピーカーであるジェンセン・ファン氏は、自身の移民としての経験を通じて、夢や希望について語りました。このようなテーマは、英語スピーキングにおいてよく使われる文脈です。特に、感謝の意を表す部分や、個人的なストーリーを語ることで、聞く側に感情を伝える技術は、実際の会話において非常に役立ちます。英語の発音を良くするためには、実際のスピーチを模倣することで、自然なリズムやイントネーションを学ぶことができます。
文法と表現の文脈
このスピーチには、いくつかの重要な文法構造と表現があります：
- 感謝を表現する: "Thank you for this extraordinary honor." これはフォーマルな場で使われる典型的な表現で、敬意を示します。
- 例を挙げる: "Like many in this audience, I'm a first-generation immigrant." 具体的な例を持ち出すことで、聴衆との共感を生む技術です。
- ストーリーテリング: "My journey is their journey." 自身の経験を通して、他者にメッセージを伝える表現方法です。
これらの構造を使用することで、IELTSスピーキング対策にも役立てることができます。スピーキングの実践を行う際には、これらの表現を積極的に取り入れましょう。
よくある発音の罠
このビデオには、発音を改善するためのヒントがいくつかあります。特に注意が必要な単語やフレーズは次の通りです：
- “Carnegie Mellon”: 正しく発音するには、何度も反復練習が必要です。
- “immigrant”: この単語は音節を強調しながら発音することが重要です。
- “opportunities”: アクセントが前半にくるため、初めて聞く英語学習者には挑戦的です。
これらの言葉をYouTubeで英語学習する際に、shadow speechの技術を用いて練習することで、発音力を向上させることができます。練習を重ねることで、自然な会話が可能になり、自信を持ってスピーキングできるようになるでしょう。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
