1 00:00:00,612 --> 00:00:03,374 For the next 16 minutes, I'm going to take you on a journey 2 00:00:03,398 --> 00:00:06,484 that is probably the biggest dream of humanity: 3 00:00:06,508 --> 00:00:08,523 to understand the code of life. 4 00:00:09,072 --> 00:00:11,815 So for me, everything started many, many years ago 5 00:00:11,839 --> 00:00:14,562 when I met the first 3D printer. 6 00:00:14,586 --> 00:00:16,260 The concept was fascinating. 7 00:00:16,284 --> 00:00:18,306 A 3D printer needs three elements: 8 00:00:18,330 --> 00:00:22,464 a bit of information, some raw material, some energy, 9 00:00:22,488 --> 00:00:25,822 and it can produce any object that was not there before. 10 00:00:26,517 --> 00:00:28,654 I was doing physics, I was coming back home 11 00:00:28,678 --> 00:00:32,116 and I realized that I actually always knew a 3D printer. 12 00:00:32,140 --> 00:00:33,476 And everyone does. 13 00:00:33,500 --> 00:00:34,658 It was my mom. 14 00:00:34,682 --> 00:00:35,683 (Laughter) 15 00:00:35,707 --> 00:00:38,121 My mom takes three elements: 16 00:00:38,145 --> 00:00:42,118 a bit of information, which is between my father and my mom in this case, 17 00:00:42,142 --> 00:00:46,299 raw elements and energy in the same media, that is food, 18 00:00:46,323 --> 00:00:48,831 and after several months, produces me. 19 00:00:48,855 --> 00:00:50,667 And I was not existent before. 20 00:00:50,691 --> 00:00:54,453 So apart from the shock of my mom discovering that she was a 3D printer, 21 00:00:54,477 --> 00:00:59,215 I immediately got mesmerized by that piece, 22 00:00:59,239 --> 00:01:00,956 the first one, the information. 23 00:01:00,980 --> 00:01:03,231 What amount of information does it take 24 00:01:03,255 --> 00:01:05,191 to build and assemble a human? 25 00:01:05,215 --> 00:01:06,789 Is it much? Is it little? 26 00:01:06,813 --> 00:01:08,993 How many thumb drives can you fill? 27 00:01:09,017 --> 00:01:11,641 Well, I was studying physics at the beginning 28 00:01:11,665 --> 00:01:17,262 and I took this approximation of a human as a gigantic Lego piece. 29 00:01:17,286 --> 00:01:21,071 So, imagine that the building blocks are little atoms 30 00:01:21,095 --> 00:01:25,748 and there is a hydrogen here, a carbon here, a nitrogen here. 31 00:01:25,772 --> 00:01:27,343 So in the first approximation, 32 00:01:27,367 --> 00:01:31,710 if I can list the number of atoms that compose a human being, 33 00:01:31,734 --> 00:01:33,121 I can build it. 34 00:01:33,145 --> 00:01:35,174 Now, you can run some numbers 35 00:01:35,198 --> 00:01:38,475 and that happens to be quite an astonishing number. 36 00:01:38,499 --> 00:01:41,256 So the number of atoms, 37 00:01:41,280 --> 00:01:46,035 the file that I will save in my thumb drive to assemble a little baby, 38 00:01:46,059 --> 00:01:50,726 will actually fill an entire Titanic of thumb drives -- 39 00:01:50,750 --> 00:01:53,468 multiplied 2,000 times. 40 00:01:53,957 --> 00:01:57,358 This is the miracle of life. 41 00:01:57,382 --> 00:01:59,994 Every time you see from now on a pregnant lady, 42 00:02:00,018 --> 00:02:02,874 she's assembling the biggest amount of information 43 00:02:02,898 --> 00:02:04,454 that you will ever encounter. 44 00:02:04,478 --> 00:02:07,428 Forget big data, forget anything you heard of. 45 00:02:07,452 --> 00:02:10,333 This is the biggest amount of information that exists. 46 00:02:10,357 --> 00:02:14,190 (Applause) 47 00:02:14,214 --> 00:02:18,858 But nature, fortunately, is much smarter than a young physicist, 48 00:02:18,882 --> 00:02:22,458 and in four billion years, managed to pack this information 49 00:02:22,482 --> 00:02:25,187 in a small crystal we call DNA. 50 00:02:25,605 --> 00:02:29,917 We met it for the first time in 1950 when Rosalind Franklin, 51 00:02:29,941 --> 00:02:31,497 an amazing scientist, a woman, 52 00:02:31,521 --> 00:02:32,910 took a picture of it. 53 00:02:32,934 --> 00:02:38,122 But it took us more than 40 years to finally poke inside a human cell, 54 00:02:38,146 --> 00:02:39,748 take out this crystal, 55 00:02:39,772 --> 00:02:42,852 unroll it, and read it for the first time. 56 00:02:43,615 --> 00:02:46,856 The code comes out to be a fairly simple alphabet, 57 00:02:46,880 --> 00:02:50,652 four letters: A, T, C and G. 58 00:02:50,676 --> 00:02:54,166 And to build a human, you need three billion of them. 59 00:02:54,933 --> 00:02:56,112 Three billion. 60 00:02:56,136 --> 00:02:57,715 How many are three billion? 61 00:02:57,739 --> 00:03:00,501 It doesn't really make any sense as a number, right? 62 00:03:00,525 --> 00:03:04,610 So I was thinking how I could explain myself better 63 00:03:04,634 --> 00:03:07,684 about how big and enormous this code is. 64 00:03:07,708 --> 00:03:10,762 But there is -- I mean, I'm going to have some help, 65 00:03:10,786 --> 00:03:14,013 and the best person to help me introduce the code 66 00:03:14,037 --> 00:03:17,559 is actually the first man to sequence it, Dr. Craig Venter. 67 00:03:17,583 --> 00:03:20,973 So welcome onstage, Dr. Craig Venter. 68 00:03:20,997 --> 00:03:27,928 (Applause) 69 00:03:27,952 --> 00:03:30,208 Not the man in the flesh, 70 00:03:31,448 --> 00:03:33,793 but for the first time in history, 71 00:03:33,817 --> 00:03:37,279 this is the genome of a specific human, 72 00:03:37,303 --> 00:03:41,063 printed page-by-page, letter-by-letter: 73 00:03:41,087 --> 00:03:45,083 262,000 pages of information, 74 00:03:45,107 --> 00:03:49,471 450 kilograms, shipped from the United States to Canada 75 00:03:49,495 --> 00:03:54,338 thanks to Bruno Bowden, Lulu.com, a start-up, did everything. 76 00:03:54,362 --> 00:03:55,825 It was an amazing feat. 77 00:03:55,849 --> 00:04:00,146 But this is the visual perception of what is the code of life. 78 00:04:00,170 --> 00:04:02,648 And now, for the first time, I can do something fun. 79 00:04:02,672 --> 00:04:05,219 I can actually poke inside it and read. 80 00:04:05,243 --> 00:04:09,868 So let me take an interesting book ... like this one. 81 00:04:13,077 --> 00:04:15,611 I have an annotation; it's a fairly big book. 82 00:04:15,635 --> 00:04:19,362 So just to let you see what is the code of life. 83 00:04:20,566 --> 00:04:23,957 Thousands and thousands and thousands 84 00:04:23,981 --> 00:04:26,651 and millions of letters. 85 00:04:26,675 --> 00:04:29,071 And they apparently make sense. 86 00:04:29,095 --> 00:04:30,852 Let's get to a specific part. 87 00:04:31,571 --> 00:04:32,933 Let me read it to you: 88 00:04:32,957 --> 00:04:33,978 (Laughter) 89 00:04:34,002 --> 00:04:38,008 "AAG, AAT, ATA." 90 00:04:38,965 --> 00:04:41,032 To you it sounds like mute letters, 91 00:04:41,056 --> 00:04:45,097 but this sequence gives the color of the eyes to Craig. 92 00:04:45,633 --> 00:04:47,565 I'll show you another part of the book. 93 00:04:47,589 --> 00:04:49,683 This is actually a little more complicated. 94 00:04:50,983 --> 00:04:53,630 Chromosome 14, book 132: 95 00:04:53,654 --> 00:04:55,744 (Laughter) 96 00:04:55,768 --> 00:04:57,045 As you might expect. 97 00:04:57,069 --> 00:05:00,535 (Laughter) 98 00:05:02,857 --> 00:05:07,364 "ATT, CTT, GATT." 99 00:05:08,329 --> 00:05:10,016 This human is lucky, 100 00:05:10,040 --> 00:05:14,557 because if you miss just two letters in this position -- 101 00:05:14,581 --> 00:05:16,458 two letters of our three billion -- 102 00:05:16,482 --> 00:05:18,501 he will be condemned to a terrible disease: 103 00:05:18,525 --> 00:05:19,965 cystic fibrosis. 104 00:05:19,989 --> 00:05:23,402 We have no cure for it, we don't know how to solve it, 105 00:05:23,426 --> 00:05:27,181 and it's just two letters of difference from what we are. 106 00:05:27,585 --> 00:05:30,290 A wonderful book, a mighty book, 107 00:05:31,115 --> 00:05:33,113 a mighty book that helped me understand 108 00:05:33,137 --> 00:05:35,890 and show you something quite remarkable. 109 00:05:36,480 --> 00:05:40,915 Every one of you -- what makes me, me and you, you -- 110 00:05:40,939 --> 00:05:43,893 is just about five million of these, 111 00:05:43,917 --> 00:05:45,145 half a book. 112 00:05:46,015 --> 00:05:47,678 For the rest, 113 00:05:47,702 --> 00:05:50,264 we are all absolutely identical. 114 00:05:51,008 --> 00:05:55,026 Five hundred pages is the miracle of life that you are. 115 00:05:55,050 --> 00:05:57,581 The rest, we all share it. 116 00:05:57,605 --> 00:06:00,514 So think about that again when we think that we are different. 117 00:06:00,538 --> 00:06:02,759 This is the amount that we share. 118 00:06:03,441 --> 00:06:06,870 So now that I have your attention, 119 00:06:06,894 --> 00:06:08,253 the next question is: 120 00:06:08,277 --> 00:06:09,428 How do I read it? 121 00:06:09,452 --> 00:06:10,961 How do I make sense out of it? 122 00:06:11,409 --> 00:06:15,649 Well, for however good you can be at assembling Swedish furniture, 123 00:06:15,673 --> 00:06:19,236 this instruction manual is nothing you can crack in your life. 124 00:06:19,260 --> 00:06:20,863 (Laughter) 125 00:06:20,887 --> 00:06:23,999 And so, in 2014, two famous TEDsters, 126 00:06:24,023 --> 00:06:26,563 Peter Diamandis and Craig Venter himself, 127 00:06:26,587 --> 00:06:28,514 decided to assemble a new company. 128 00:06:28,538 --> 00:06:29,950 Human Longevity was born, 129 00:06:29,974 --> 00:06:31,344 with one mission: 130 00:06:31,368 --> 00:06:33,229 trying everything we can try 131 00:06:33,253 --> 00:06:36,012 and learning everything we can learn from these books, 132 00:06:36,036 --> 00:06:37,741 with one target -- 133 00:06:38,862 --> 00:06:41,663 making real the dream of personalized medicine, 134 00:06:41,687 --> 00:06:45,454 understanding what things should be done to have better health 135 00:06:45,478 --> 00:06:47,761 and what are the secrets in these books. 136 00:06:48,329 --> 00:06:52,579 An amazing team, 40 data scientists and many, many more people, 137 00:06:52,603 --> 00:06:53,953 a pleasure to work with. 138 00:06:53,977 --> 00:06:56,230 The concept is actually very simple. 139 00:06:56,254 --> 00:06:59,412 We're going to use a technology called machine learning. 140 00:06:59,436 --> 00:07:03,975 On one side, we have genomes -- thousands of them. 141 00:07:03,999 --> 00:07:07,996 On the other side, we collected the biggest database of human beings: 142 00:07:08,020 --> 00:07:12,316 phenotypes, 3D scan, NMR -- everything you can think of. 143 00:07:12,340 --> 00:07:15,239 Inside there, on these two opposite sides, 144 00:07:15,263 --> 00:07:17,705 there is the secret of translation. 145 00:07:17,729 --> 00:07:20,201 And in the middle, we build a machine. 146 00:07:20,801 --> 00:07:23,186 We build a machine and we train a machine -- 147 00:07:23,210 --> 00:07:26,420 well, not exactly one machine, many, many machines -- 148 00:07:26,444 --> 00:07:30,988 to try to understand and translate the genome in a phenotype. 149 00:07:31,362 --> 00:07:34,702 What are those letters, and what do they do? 150 00:07:34,726 --> 00:07:37,473 It's an approach that can be used for everything, 151 00:07:37,497 --> 00:07:40,490 but using it in genomics is particularly complicated. 152 00:07:40,514 --> 00:07:43,790 Little by little we grew and we wanted to build different challenges. 153 00:07:43,814 --> 00:07:46,546 We started from the beginning, from common traits. 154 00:07:46,570 --> 00:07:49,173 Common traits are comfortable because they are common, 155 00:07:49,197 --> 00:07:50,381 everyone has them. 156 00:07:50,405 --> 00:07:52,899 So we started to ask our questions: 157 00:07:52,923 --> 00:07:54,303 Can we predict height? 158 00:07:54,985 --> 00:07:57,162 Can we read the books and predict your height? 159 00:07:57,186 --> 00:07:58,337 Well, we actually can, 160 00:07:58,361 --> 00:08:00,154 with five centimeters of precision. 161 00:08:00,178 --> 00:08:03,313 BMI is fairly connected to your lifestyle, 162 00:08:03,337 --> 00:08:07,201 but we still can, we get in the ballpark, eight kilograms of precision. 163 00:08:07,225 --> 00:08:08,456 Can we predict eye color? 164 00:08:08,480 --> 00:08:09,638 Yeah, we can. 165 00:08:09,662 --> 00:08:10,986 Eighty percent accuracy. 166 00:08:11,466 --> 00:08:13,324 Can we predict skin color? 167 00:08:13,348 --> 00:08:15,789 Yeah we can, 80 percent accuracy. 168 00:08:15,813 --> 00:08:17,153 Can we predict age? 169 00:08:18,121 --> 00:08:21,860 We can, because apparently, the code changes during your life. 170 00:08:21,884 --> 00:08:25,166 It gets shorter, you lose pieces, it gets insertions. 171 00:08:25,190 --> 00:08:27,745 We read the signals, and we make a model. 172 00:08:28,438 --> 00:08:29,913 Now, an interesting challenge: 173 00:08:29,937 --> 00:08:31,666 Can we predict a human face? 174 00:08:33,014 --> 00:08:34,292 It's a little complicated, 175 00:08:34,316 --> 00:08:37,507 because a human face is scattered among millions of these letters. 176 00:08:37,531 --> 00:08:40,160 And a human face is not a very well-defined object. 177 00:08:40,184 --> 00:08:42,235 So, we had to build an entire tier of it 178 00:08:42,259 --> 00:08:44,969 to learn and teach a machine what a face is, 179 00:08:44,993 --> 00:08:47,030 and embed and compress it. 180 00:08:47,054 --> 00:08:49,302 And if you're comfortable with machine learning, 181 00:08:49,326 --> 00:08:51,610 you understand what the challenge is here. 182 00:08:52,108 --> 00:08:58,099 Now, after 15 years -- 15 years after we read the first sequence -- 183 00:08:58,123 --> 00:09:01,025 this October, we started to see some signals. 184 00:09:01,049 --> 00:09:03,504 And it was a very emotional moment. 185 00:09:03,528 --> 00:09:07,273 What you see here is a subject coming in our lab. 186 00:09:07,619 --> 00:09:09,547 This is a face for us. 187 00:09:09,571 --> 00:09:13,202 So we take the real face of a subject, we reduce the complexity, 188 00:09:13,226 --> 00:09:15,196 because not everything is in your face -- 189 00:09:15,220 --> 00:09:19,006 lots of features and defects and asymmetries come from your life. 190 00:09:19,030 --> 00:09:22,499 We symmetrize the face, and we run our algorithm. 191 00:09:23,245 --> 00:09:25,143 The results that I show you right now, 192 00:09:25,167 --> 00:09:28,539 this is the prediction we have from the blood. 193 00:09:29,596 --> 00:09:31,120 (Applause) 194 00:09:31,144 --> 00:09:32,579 Wait a second. 195 00:09:32,603 --> 00:09:37,295 In these seconds, your eyes are watching, left and right, left and right, 196 00:09:37,319 --> 00:09:41,249 and your brain wants those pictures to be identical. 197 00:09:41,273 --> 00:09:43,719 So I ask you to do another exercise, to be honest. 198 00:09:43,743 --> 00:09:46,030 Please search for the differences, 199 00:09:46,054 --> 00:09:47,415 which are many. 200 00:09:47,439 --> 00:09:50,042 The biggest amount of signal comes from gender, 201 00:09:50,066 --> 00:09:55,267 then there is age, BMI, the ethnicity component of a human. 202 00:09:55,291 --> 00:09:59,002 And scaling up over that signal is much more complicated. 203 00:09:59,026 --> 00:10:02,276 But what you see here, even in the differences, 204 00:10:02,300 --> 00:10:05,895 lets you understand that we are in the right ballpark, 205 00:10:05,919 --> 00:10:07,267 that we are getting closer. 206 00:10:07,291 --> 00:10:09,640 And it's already giving you some emotions. 207 00:10:09,664 --> 00:10:12,367 This is another subject that comes in place, 208 00:10:12,391 --> 00:10:13,800 and this is a prediction. 209 00:10:13,824 --> 00:10:18,420 A little smaller face, we didn't get the complete cranial structure, 210 00:10:18,444 --> 00:10:21,095 but still, it's in the ballpark. 211 00:10:21,634 --> 00:10:23,858 This is a subject that comes in our lab, 212 00:10:23,882 --> 00:10:25,325 and this is the prediction. 213 00:10:26,056 --> 00:10:30,732 So these people have never been seen in the training of the machine. 214 00:10:30,756 --> 00:10:33,593 These are the so-called "held-out" set. 215 00:10:33,617 --> 00:10:37,357 But these are people that you will probably never believe. 216 00:10:37,381 --> 00:10:40,057 We're publishing everything in a scientific publication, 217 00:10:40,081 --> 00:10:41,232 you can read it. 218 00:10:41,256 --> 00:10:43,600 But since we are onstage, Chris challenged me. 219 00:10:43,624 --> 00:10:47,250 I probably exposed myself and tried to predict 220 00:10:47,274 --> 00:10:50,105 someone that you might recognize. 221 00:10:50,470 --> 00:10:54,895 So, in this vial of blood -- and believe me, you have no idea 222 00:10:54,919 --> 00:10:57,799 what we had to do to have this blood now, here -- 223 00:10:57,823 --> 00:11:01,724 in this vial of blood is the amount of biological information 224 00:11:01,748 --> 00:11:04,025 that we need to do a full genome sequence. 225 00:11:04,049 --> 00:11:06,119 We just need this amount. 226 00:11:06,528 --> 00:11:09,733 We ran this sequence, and I'm going to do it with you. 227 00:11:09,757 --> 00:11:13,736 And we start to layer up all the understanding we have. 228 00:11:13,760 --> 00:11:17,110 In the vial of blood, we predicted he's a male. 229 00:11:17,134 --> 00:11:18,498 And the subject is a male. 230 00:11:18,996 --> 00:11:21,434 We predict that he's a meter and 76 cm. 231 00:11:21,458 --> 00:11:23,850 The subject is a meter and 77 cm. 232 00:11:23,874 --> 00:11:27,984 So, we predicted that he's 76; the subject is 82. 233 00:11:28,701 --> 00:11:31,333 We predict his age, 38. 234 00:11:31,357 --> 00:11:33,261 The subject is 35. 235 00:11:33,851 --> 00:11:35,975 We predict his eye color. 236 00:11:36,824 --> 00:11:38,035 Too dark. 237 00:11:38,059 --> 00:11:39,614 We predict his skin color. 238 00:11:40,026 --> 00:11:41,436 We are almost there. 239 00:11:41,899 --> 00:11:43,272 That's his face. 240 00:11:45,172 --> 00:11:48,441 Now, the reveal moment: 241 00:11:48,465 --> 00:11:50,235 the subject is this person. 242 00:11:50,259 --> 00:11:52,194 (Laughter) 243 00:11:52,218 --> 00:11:54,276 And I did it intentionally. 244 00:11:54,300 --> 00:11:57,992 I am a very particular and peculiar ethnicity. 245 00:11:58,016 --> 00:12:00,966 Southern European, Italians -- they never fit in models. 246 00:12:00,990 --> 00:12:06,120 And it's particular -- that ethnicity is a complex corner case for our model. 247 00:12:06,144 --> 00:12:07,653 But there is another point. 248 00:12:07,677 --> 00:12:11,154 So, one of the things that we use a lot to recognize people 249 00:12:11,178 --> 00:12:12,900 will never be written in the genome. 250 00:12:12,924 --> 00:12:15,241 It's our free will, it's how I look. 251 00:12:15,265 --> 00:12:18,494 Not my haircut in this case, but my beard cut. 252 00:12:18,518 --> 00:12:22,071 So I'm going to show you, I'm going to, in this case, transfer it -- 253 00:12:22,095 --> 00:12:24,860 and this is nothing more than Photoshop, no modeling -- 254 00:12:24,884 --> 00:12:26,597 the beard on the subject. 255 00:12:26,621 --> 00:12:30,093 And immediately, we get much, much better in the feeling. 256 00:12:30,955 --> 00:12:33,664 So, why do we do this? 257 00:12:35,938 --> 00:12:41,078 We certainly don't do it for predicting height 258 00:12:41,102 --> 00:12:43,474 or taking a beautiful picture out of your blood. 259 00:12:44,390 --> 00:12:48,408 We do it because the same technology and the same approach, 260 00:12:48,432 --> 00:12:50,952 the machine learning of this code, 261 00:12:50,976 --> 00:12:54,113 is helping us to understand how we work, 262 00:12:54,137 --> 00:12:55,623 how your body works, 263 00:12:55,647 --> 00:12:57,312 how your body ages, 264 00:12:57,336 --> 00:13:00,105 how disease generates in your body, 265 00:13:00,129 --> 00:13:03,101 how your cancer grows and develops, 266 00:13:03,125 --> 00:13:04,908 how drugs work 267 00:13:04,932 --> 00:13:07,246 and if they work on your body. 268 00:13:07,713 --> 00:13:09,380 This is a huge challenge. 269 00:13:09,894 --> 00:13:11,532 This is a challenge that we share 270 00:13:11,556 --> 00:13:14,135 with thousands of other researchers around the world. 271 00:13:14,159 --> 00:13:16,381 It's called personalized medicine. 272 00:13:17,125 --> 00:13:20,585 It's the ability to move from a statistical approach 273 00:13:20,609 --> 00:13:22,641 where you're a dot in the ocean, 274 00:13:22,665 --> 00:13:24,478 to a personalized approach, 275 00:13:24,502 --> 00:13:26,687 where we read all these books 276 00:13:26,711 --> 00:13:29,575 and we get an understanding of exactly how you are. 277 00:13:30,260 --> 00:13:33,622 But it is a particularly complicated challenge, 278 00:13:33,646 --> 00:13:37,644 because of all these books, as of today, 279 00:13:37,668 --> 00:13:40,310 we just know probably two percent: 280 00:13:41,027 --> 00:13:44,680 four books of more than 175. 281 00:13:46,021 --> 00:13:49,227 And this is not the topic of my talk, 282 00:13:50,145 --> 00:13:52,743 because we will learn more. 283 00:13:53,378 --> 00:13:56,047 There are the best minds in the world on this topic. 284 00:13:57,048 --> 00:13:58,882 The prediction will get better, 285 00:13:58,906 --> 00:14:01,159 the model will get more precise. 286 00:14:01,183 --> 00:14:03,041 And the more we learn, 287 00:14:03,065 --> 00:14:07,895 the more we will be confronted with decisions 288 00:14:07,919 --> 00:14:10,940 that we never had to face before 289 00:14:10,964 --> 00:14:12,399 about life, 290 00:14:12,423 --> 00:14:14,097 about death, 291 00:14:14,121 --> 00:14:15,724 about parenting. 292 00:14:20,626 --> 00:14:25,372 So, we are touching the very inner detail on how life works. 293 00:14:26,118 --> 00:14:29,276 And it's a revolution that cannot be confined 294 00:14:29,300 --> 00:14:31,959 in the domain of science or technology. 295 00:14:32,960 --> 00:14:35,204 This must be a global conversation. 296 00:14:35,798 --> 00:14:41,015 We must start to think of the future we're building as a humanity. 297 00:14:41,039 --> 00:14:45,103 We need to interact with creatives, with artists, with philosophers, 298 00:14:45,127 --> 00:14:46,637 with politicians. 299 00:14:46,661 --> 00:14:47,819 Everyone is involved, 300 00:14:47,843 --> 00:14:50,668 because it's the future of our species. 301 00:14:51,273 --> 00:14:55,241 Without fear, but with the understanding 302 00:14:55,265 --> 00:14:59,136 that the decisions that we make in the next year 303 00:14:59,160 --> 00:15:02,949 will change the course of history forever. 304 00:15:03,732 --> 00:15:04,892 Thank you. 305 00:15:04,916 --> 00:15:15,075 (Applause)
