So, there's about seven and a half billion of us.
0
12641
3287
00:16
The World Health Organization tells us that 300 million of us are depressed,
1
16635
3871
00:21
and about 800,000 people take their lives every year.
2
21214
2875
00:24
A tiny subset of them choose a profoundly nihilistic route,
3
24803
4074
00:28
which is they die in the act of killing as many people as possible.
4
28901
4215
00:33
These are some famous recent examples.
5
33140
2339
00:36
And here's a less famous one. It happened about nine weeks ago.
6
36019
3033
00:39
If you don't remember it,
7
39076
1192
00:40
it's because there's a lot of this going on.
8
40292
2082
00:42
Wikipedia just last year counted 323 mass shootings
9
42398
4681
00:47
in my home country, the United States.
10
47103
2981
00:50
Not all of those shooters were suicidal,
11
50108
2214
00:52
not all of them were maximizing their death tolls,
12
52346
2796
00:55
but many, many were.
13
55166
1230
00:56
An important question becomes: What limits do these people have?
14
56970
3574
01:00
Take the Vegas shooter.
15
60568
1506
01:02
He slaughtered 58 people.
16
62098
2878
01:05
Did he stop there because he'd had enough?
17
65342
2102
01:07
No, and we know this because he shot and injured another 422 people
18
67801
5644
01:13
who he surely would have preferred to kill.
19
73469
2294
01:16
We have no reason to think he would have stopped at 4,200.
20
76283
2740
01:19
In fact, with somebody this nihilistic, he may well have gladly killed us all.
21
79047
3958
01:23
We don't know.
22
83029
1192
01:24
What we do know is this:
23
84953
2047
01:27
when suicidal murderers really go all in,
24
87024
3419
01:30
technology is the force multiplier.
25
90467
2936
01:33
Here's an example.
26
93843
1410
01:35
Several years back, there was a rash of 10 mass school attacks in China
27
95277
4999
01:40
carried out with things like knives and hammers and cleavers,
28
100300
3702
01:44
because guns are really hard to get there.
29
104026
2047
01:46
By macabre coincidence, this last attack occurred
30
106097
3987
01:50
just hours before the massacre in Newtown, Connecticut.
31
110108
3893
01:54
But that one American attack killed roughly the same number of victims
32
114025
4382
01:58
as the 10 Chinese attacks combined.
33
118431
2921
02:01
So we can fairly say, knife: terrible; gun: way worse.
34
121376
5873
02:07
And airplane: massively worse,
35
127273
2713
02:10
as pilot Andreas Lubitz showed when he forced 149 people
36
130010
4207
02:14
to join him in his suicide,
37
134241
2016
02:16
smashing a plane into the French Alps.
38
136281
2338
02:19
And there are other examples of this.
39
139046
2786
02:21
And I'm afraid there are far more deadly weapons in our near future than airplanes,
40
141856
5048
02:26
ones not made of metal.
41
146928
1603
02:29
So let's consider the apocalyptic dynamics that will ensue
42
149125
5122
02:34
if suicidal mass murder hitches a ride on a rapidly advancing field
43
154271
4874
02:39
that for the most part holds boundless promise for society.
44
159169
3804
02:43
Somewhere out there in the world, there's a tiny group of people
45
163606
3060
02:46
who would attempt, however ineptly,
46
166690
2601
02:49
to kill us all if they could just figure out how.
47
169315
2778
02:52
The Vegas shooter may or may not have been one of them,
48
172736
2699
02:55
but with seven and a half billion of us,
49
175459
1957
02:57
this is a nonzero population.
50
177440
2434
02:59
There's plenty of suicidal nihilists out there.
51
179898
2244
03:02
We've already seen that.
52
182166
1195
03:03
There's people with severe mood disorders that they can't even control.
53
183385
3704
03:07
There are people who have just suffered deranging traumas, etc. etc.
54
187113
5368
03:12
As for the corollary group,
55
192993
1656
03:14
its size was simply zero forever until the Cold War,
56
194673
4702
03:19
when suddenly, the leaders of two global alliances
57
199399
2828
03:22
attained the ability to blow up the world.
58
202251
2546
03:26
The number of people with actual doomsday buttons
59
206043
3513
03:29
has stayed fairly stable since then.
60
209580
2644
03:32
But I'm afraid it's about to grow,
61
212248
2185
03:34
and not just to three.
62
214457
1598
03:36
This is going off the charts.
63
216079
1418
03:37
I mean, it's going to look like a tech business plan.
64
217521
2601
03:40
(Laughter)
65
220146
2152
03:44
And the reason is,
66
224264
1664
03:45
we're in the era of exponential technologies,
67
225952
2340
03:48
which routinely take eternal impossibilities
68
228316
4787
03:53
and make them the actual superpowers of one or two living geniuses
69
233127
5809
03:58
and -- this is the big part --
70
238960
1783
04:00
then diffuse those powers to more or less everybody.
71
240767
2658
04:03
Now, here's a benign example.
72
243853
1668
04:05
If you wanted to play checkers with a computer in 1952,
73
245545
4646
04:10
you literally had to be that guy,
74
250215
3483
04:13
then commandeer one of the world's 19 copies of that computer,
75
253722
4985
04:18
then used your Nobel-adjacent brain to teach it checkers.
76
258731
3626
04:22
That was the bar.
77
262381
1218
04:24
Today, you just need to know someone who knows someone who owns a telephone,
78
264869
4692
04:29
because computing is an exponential technology.
79
269585
3195
04:33
So is synthetic biology,
80
273243
2014
04:35
which I'll now refer to as "synbio."
81
275281
2108
04:38
And in 2011, a couple of researchers did something every bit as ingenious
82
278006
5690
04:43
and unprecedented as the checkers trick
83
283720
3106
04:46
with H5N1 flu.
84
286850
1791
04:49
This is a strain that kills up to 60 percent of the people it infects,
85
289435
4656
04:54
more than Ebola.
86
294115
1695
04:55
But it is so uncontagious
87
295834
2670
04:58
that it's killed fewer than 50 people since 2015.
88
298528
4020
05:02
So these researchers edited H5N1's genome
89
302572
4063
05:06
and made it every bit as deadly, but also wildly contagious.
90
306659
4592
05:11
The news arm of one of the world's top two scientific journals
91
311275
3349
05:14
said if this thing got out, it would likely cause a pandemic
92
314648
3817
05:18
with perhaps millions of deaths.
93
318489
2264
05:20
And Dr. Paul Keim said
94
320777
1869
05:22
he could not think of an organism as scary as this,
95
322670
3949
05:26
which is the last thing I personally want to hear
96
326643
3099
05:29
from the Chairman of the National Science Advisory Board on Biosecurity.
97
329766
4475
05:34
And by the way, Dr. Keim also said this --
98
334689
2894
05:37
["I don't think anthrax is scary at all compared to this."]
99
337607
2802
05:40
And he's also one of these.
100
340433
1305
05:41
[Anthrax expert] (Laughter)
101
341762
1330
05:43
Now, the good news about the 2011 biohack
102
343116
3601
05:46
is that the people who did it didn't mean us any harm.
103
346741
3063
05:49
They're virologists.
104
349828
1192
05:51
They believed they were advancing science.
105
351044
2167
05:53
The bad news is that technology does not freeze in place,
106
353235
3743
05:57
and over the next few decades,
107
357002
2028
05:59
their feat will become trivially easy.
108
359054
3078
06:02
In fact, it's already way easier, because as we learned yesterday morning,
109
362559
3840
06:06
just two years after they did their work,
110
366423
1954
06:08
the CRISPR system was harnessed for genome editing.
111
368401
3504
06:11
This was a radical breakthrough
112
371929
1904
06:13
that makes gene editing massively easier --
113
373857
3278
06:17
so easy that CRISPR is now taught in high schools.
114
377159
3154
06:20
And this stuff is moving quicker than computing.
115
380825
3300
06:24
That slow, stodgy white line up there?
116
384149
3111
06:27
That's Moore's law.
117
387284
2258
06:29
That shows us how quickly computing is getting cheaper.
118
389566
3780
06:33
That steep, crazy-fun green line,
119
393370
3033
06:36
that shows us how quickly genetic sequencing is getting cheaper.
120
396427
4064
06:40
Now, gene editing and synthesis and sequencing,
121
400515
3598
06:44
they're different disciplines, but they're tightly related.
122
404137
2803
06:46
And they're all moving in these headlong rates.
123
406964
2249
06:49
And the keys to the kingdom are these tiny, tiny data files.
124
409237
3727
06:52
That is an excerpt of H5N1's genome.
125
412988
3908
06:56
The whole thing can fit on just a few pages.
126
416920
2903
06:59
And yeah, don't worry, you can Google this as soon as you get home.
127
419847
3209
07:03
It's all over the internet, right?
128
423080
1734
07:04
And the part that made it contagious
129
424838
1934
07:06
could well fit on a single Post-it note.
130
426796
2334
07:09
And once a genius makes a data file,
131
429154
3997
07:13
any idiot can copy it,
132
433175
2327
07:15
distribute it worldwide
133
435526
2021
07:17
or print it.
134
437571
1636
07:19
And I don't just mean print it on this,
135
439231
2692
07:21
but soon enough, on this.
136
441947
2555
07:24
So let's imagine a scenario.
137
444993
1903
07:27
Let's say it's 2026, to pick an arbitrary year,
138
447287
3336
07:30
and a brilliant virologist, hoping to advance science
139
450647
2976
07:33
and better understand pandemics,
140
453647
2306
07:35
designs a new bug.
141
455977
1496
07:37
It's as contagious as chicken pox,
142
457957
2154
07:40
it's as deadly as Ebola,
143
460135
1920
07:42
and it incubates for months and months before causing an outbreak,
144
462079
4008
07:46
so the whole world can be infected before the first sign of trouble.
145
466111
4215
07:50
Then, her university gets hacked.
146
470707
2511
07:53
And of course, this is not science fiction.
147
473242
2422
07:55
In fact, just one recent US indictment
148
475688
2186
07:57
documents the hacking of over 300 universities.
149
477898
3370
08:01
So that file with the bug's genome on it spreads to the internet's dark corners.
150
481996
5521
08:07
And once a file is out there, it never comes back --
151
487541
3653
08:11
just ask anybody who runs a movie studio or a music label.
152
491218
4183
08:16
So now maybe in 2026,
153
496001
2972
08:18
it would take a true genius like our virologist
154
498997
2205
08:21
to make the actual living critter,
155
501226
2621
08:23
but 15 years later,
156
503871
1926
08:25
it may just take a DNA printer you can find at any high school.
157
505821
3593
08:29
And if not?
158
509883
1182
08:31
Give it a couple of decades.
159
511514
1948
08:34
So, a quick aside:
160
514248
2410
08:36
Remember this slide here?
161
516682
1242
08:37
Turn your attention to these two words.
162
517948
2319
08:40
If somebody tries this and is only 0.1 percent effective,
163
520840
6280
08:47
eight million people die.
164
527144
1803
08:48
That's 2,500 9/11s.
165
528971
3639
08:52
Civilization would survive,
166
532634
2406
08:55
but it would be permanently disfigured.
167
535064
2786
08:58
So this means we need to be concerned about anybody
168
538586
3150
09:01
who has the faintest shot on goal,
169
541760
2124
09:03
not just geniuses.
170
543908
1867
09:06
So today, there's a tiny handful of geniuses
171
546688
5047
09:11
who probably could make a doomsday bug
172
551759
2142
09:13
that's .1-percent effective and maybe even a little bit more.
173
553925
3119
09:17
They tend to be stable and successful and so not part of this group.
174
557068
5005
09:22
So I guess I'm sorta kinda barely OK-ish with that.
175
562097
3273
09:26
But what about after technology improves
176
566307
2872
09:29
and diffuses
177
569203
1580
09:30
and thousands of life science grad students are enabled?
178
570807
3327
09:34
Are every single one of them going to be perfectly stable?
179
574158
3548
09:37
Or how about a few years after that,
180
577730
1824
09:39
where every stress-ridden premed is fully enabled?
181
579578
3709
09:43
At some point in that time frame,
182
583311
1892
09:45
these circles are going to intersect,
183
585227
2321
09:47
because we're now starting to talk about hundreds of thousands of people
184
587572
3480
09:51
throughout the world.
185
591076
1159
09:52
And they recently included that guy who dressed up like the Joker
186
592259
4058
09:56
and shot 12 people to death at a Batman premiere.
187
596341
3252
09:59
That was a neuroscience PhD student
188
599617
2147
10:01
with an NIH grant.
189
601788
1912
10:05
OK, plot twist:
190
605478
1526
10:07
I think we can actually survive this one if we start focusing on it now.
191
607028
4895
10:11
And I say this, having spent countless hours
192
611947
2970
10:14
interviewing global leaders in synbio
193
614941
2972
10:17
and also researching their work for science podcasts I create.
194
617937
4034
10:21
I have come to fear their work, in case I haven't gotten that out there yet --
195
621995
5138
10:27
(Laughter)
196
627157
1548
10:28
but more than that, to revere its potential.
197
628729
3348
10:32
This stuff will cure cancer, heal our environment
198
632101
3854
10:35
and stop our cruel treatment of other creatures.
199
635979
3301
10:39
So how do we get all this without, you know, annihilating ourselves?
200
639942
3670
10:44
First thing: like it or not, synbio is here,
201
644091
3831
10:47
so let's embrace the technology.
202
647946
1894
10:49
If we do a tech ban,
203
649864
1857
10:51
that would only hand the wheel to bad actors.
204
651745
3157
10:54
Unlike nuclear programs,
205
654926
2356
10:57
biology can be practiced invisibly.
206
657306
2456
10:59
Massive Soviet cheating on bioweapons treaties
207
659786
3357
11:03
made that very clear, as does every illegal drug lab in the world.
208
663167
4129
11:07
Secondly, enlist the experts.
209
667825
2224
11:10
Let's sign them up and make more of them.
210
670073
2008
11:12
For every million and one bioengineers we have,
211
672105
2618
11:14
at least a million of them are going to be on our side.
212
674747
3685
11:18
I mean, Al Capone would be on our side in this one.
213
678858
2821
11:21
The bar to being a good guy is just so low.
214
681703
2810
11:25
And massive numerical advantages do matter,
215
685386
3281
11:28
even when a single bad guy can inflict grievous harm,
216
688691
2889
11:31
because among many other things,
217
691604
1575
11:33
they allow us to exploit the hell out of this:
218
693203
2516
11:35
we have years and hopefully decades to prepare and prevent.
219
695743
5922
11:41
The first person to try something awful -- and there will be somebody --
220
701689
3488
11:45
may not even be born yet.
221
705201
1261
11:47
Next, this needs to be an effort that spans society,
222
707068
3525
11:50
and all of you need to be a part of it,
223
710617
2774
11:53
because we cannot ask a tiny group of experts
224
713415
4170
11:57
to be responsible for both containing and exploiting synthetic biology,
225
717609
5138
12:02
because we already tried that with the financial system,
226
722771
3122
12:05
and our stewards became massively corrupted
227
725917
3514
12:09
as they figured out how they could cut corners,
228
729455
2246
12:11
inflict massive, massive risks on the rest of us
229
731725
3011
12:14
and privatize the gains,
230
734760
1917
12:16
becoming repulsively wealthy
231
736701
2067
12:18
while they stuck us with the $22 trillion bill.
232
738792
2634
12:22
And more recently --
233
742723
1467
12:24
(Applause)
234
744214
2230
12:26
Are you the ones who have gotten the thank-you letters?
235
746468
2713
12:29
I'm still waiting for mine.
236
749205
1298
12:30
I just figured they were too busy to be grateful.
237
750527
2756
12:33
And much more recently,
238
753307
1936
12:36
online privacy started looming as a huge issue,
239
756291
3312
12:39
and we basically outsourced it.
240
759627
1946
12:41
And once again:
241
761597
1347
12:42
privatized gains, socialized losses.
242
762968
2558
12:45
Is anybody else sick of this pattern?
243
765550
2065
12:47
(Applause)
244
767639
4623
12:52
So we need a more inclusive way to safeguard our prosperity,
245
772286
5959
12:58
our privacy
246
778269
1157
12:59
and soon, our lives.
247
779450
1766
13:01
So how do we do all of this?
248
781240
2738
13:04
Well, when bodies fight pathogens,
249
784002
2668
13:06
they use ingenious immune systems,
250
786694
2398
13:09
which are very complex and multilayered.
251
789116
2045
13:11
Why don't we build one of these for the whole damn ecosystem?
252
791185
2938
13:14
There's a year of TED Talks that could be given on this first critical layer.
253
794147
3668
13:17
So these are just a couple of many great ideas that are out there.
254
797839
3480
13:21
Some R and D muscle
255
801343
1986
13:23
could take the very primitive pathogen sensors that we currently have
256
803353
4935
13:28
and put them on a very steep price performance curve
257
808312
2823
13:31
that would quickly become ingenious
258
811159
2130
13:33
and networked
259
813313
1154
13:34
and gradually as widespread as smoke detectors and even smartphones.
260
814491
4328
13:38
On a very related note:
261
818843
1967
13:40
vaccines have all kinds of problems
262
820834
2627
13:43
when it comes to manufacturing and distribution,
263
823485
3021
13:46
and once they're made, they can't adapt to new threats or mutations.
264
826530
4555
13:51
We need an agile biomanufacturing base
265
831109
2819
13:53
extending into every single pharmacy and maybe even our homes.
266
833952
4090
13:58
Printer technology for vaccines and medicines is within reach
267
838066
3659
14:01
if we prioritize it.
268
841749
1983
14:03
Next, mental health.
269
843756
2070
14:05
Many people who commit suicidal mass murder
270
845850
2855
14:08
suffer from crippling, treatment-resistant depression or PTSD.
271
848729
4484
14:13
We need noble researchers like Rick Doblin working on this,
272
853237
4071
14:17
but we also need the selfish jerks who are way more numerous
273
857332
3938
14:21
to appreciate the fact that acute suffering will soon endanger all of us,
274
861294
6020
14:27
not just those afflicted.
275
867338
1730
14:29
Those jerks will then join us and Al Capone
276
869092
3450
14:32
in fighting this condition.
277
872566
2254
14:35
Third, each and every one of us can be and should be a white blood cell
278
875409
5618
14:41
in this immune system.
279
881051
1850
14:43
Suicidal mass murderers can be despicable, yes,
280
883280
3475
14:46
but they're also terribly broken and sad people,
281
886779
4109
14:50
and those of us who aren't need to do what we can
282
890912
2420
14:53
to make sure nobody goes unloved.
283
893356
2087
14:56
(Applause)
284
896573
4684
15:01
Next, we need to make fighting these dangers
285
901711
2569
15:04
core to the discipline of synthetic biology.
286
904304
2760
15:07
There are companies out there that at least claim
287
907088
2367
15:09
they let their engineers spend 20 percent of their time
288
909479
2902
15:12
doing whatever they want.
289
912405
1394
15:13
What if those who hire bioengineers
290
913823
2652
15:16
and become them
291
916499
1168
15:17
give 20 percent of their time to building defenses for the common good?
292
917691
3881
15:23
Not a bad idea, right?
293
923397
1371
15:24
(Applause)
294
924792
1218
15:26
Then, finally: this won't be any fun.
295
926034
2640
15:28
But we need to let our minds go to some very, very dark places,
296
928698
3947
15:32
and thank you for letting me take you there this evening.
297
932669
3412
15:36
We survived the Cold War
298
936105
2367
15:38
because every one of us understood and respected the danger,
299
938496
4353
15:42
in part, because we had spent decades
300
942873
2387
15:45
telling ourselves terrifying ghost stories
301
945284
2477
15:47
with names like "Dr. Strangelove"
302
947785
1960
15:49
and "War Games."
303
949769
1615
15:51
This is no time to remain calm.
304
951408
2296
15:53
This is one of those rare times when it's incredibly productive
305
953728
3068
15:56
to freak the hell out --
306
956820
2658
15:59
(Laughter)
307
959502
2769
16:02
to come up with some ghost stories
308
962295
2097
16:04
and use our fear as fuel to fight this danger.
309
964416
4865
16:09
Because, all these terrible scenarios I've painted --
310
969771
4054
16:13
they are not destiny.
311
973849
1909
16:16
They're optional.
312
976171
1357
16:18
The danger is still kind of distant.
313
978012
3607
16:22
And that means it will only befall us
314
982247
2763
16:25
if we allow it to.
315
985034
2188
16:27
Let's not.
316
987950
1194
16:29
Thank you very much for listening.
317
989168
1716
16:30
(Applause)
