00:06
Imagine that your life began roughly 300,000 years ago
0
6961
3962
想像你嘅人生 大概喺 30 萬年前開始
00:10
as one of the planet’s first humans.
1
10923
2128
係地球上最早嘅人類之一
00:13
At this time, you live in Africa near modern-day Morocco,
2
13342
3337
嗰個時候你生活喺非洲 而家嘅摩洛哥附近
00:16
and your life isn’t too different from that of your hominid parents.
3
16679
3420
你嘅生活方式 唔係同猩猩科父母好大分別
00:20
You make crude tools, hunt, and gather food and materials,
4
20099
4546
你係製造啲簡陋嘅工具 打獵同埋收集食物及物料
00:24
until, eventually, you perish.
5
24645
3003
直到終有一日你死咗
00:28
But this is only the beginning.
6
28274
2085
但係呢個只係開始
00:30
Because after dying, you travel back in time to be reincarnated
7
30485
4254
因為你死咗之後 會穿越時空嚟轉世
00:34
as the second human ever to live.
8
34864
2669
成為世上第二個人類
00:37
While you don't remember your former life,
9
37992
2461
雖然你忘記咗以前嘅人生
00:40
your previous actions affect you nonetheless.
10
40995
2795
然而過去嘅行為 仍然影響現在嘅你
00:45
And after dying once more, you return as the third person, then the fourth,
11
45291
4880
每次死亡,你又返返嚟 成為第三、第四
00:50
the fifth, and so on—
12
50171
1418
第五個人等等
00:51
living the lives of every single human that’s ever walked the Earth.
13
51589
4379
經歷世上每個人踏足喺地球上嘅生活
00:56
Strung end to end, these lives last almost 4 trillion years.
14
56636
4671
首尾相連,呢啲生命 大概四萬億年
01:01
Since you only recall the life you’re currently living,
15
61432
3504
由於你只係諗到而家嘅生活
01:04
your psyche doesn’t carry the entire weight of human history.
16
64936
3420
你心理上並冇孭起 成個嘅人類歷史
01:08
However, each of your lifetimes still has a profound impact on your future selves.
17
68648
5297
但係每個生命嘅體現 對未來嘅自己有深遠嘅影響
有時你對呢個世界 係有好明顯嘅影響
01:14
Sometimes your influence on the world is obvious,
18
74112
2711
01:16
but these major historical figures only account
19
76823
2502
但作為呢啲重要喺歷史人物
01:19
for a tiny fraction of your experience.
20
79325
2669
只算係罕有嘅經歷
01:22
Instead, your existence consists mostly of ordinary lives,
21
82286
4046
反而你大部分時間 喺好平凡嘅生活渡過
01:26
filled with everyday tasks like eating, laughing, working, and worrying.
22
86332
4755
充滿著每日嘅例行公事 譬如食嘢、歡笑、工作同埋焦慮
01:31
For approximately one tenth of your 4 trillion years,
23
91295
3504
大概四萬億年嘅十分之一
01:34
you’re a hunter-gatherer.
24
94799
1501
你係一位漁獵採集者
01:36
For 60%, you’re an agriculturalist, developing tools and techniques
25
96509
4546
有 60% 時間,你係農業家 喺度發展工具同技術
01:41
which you employ over roughly 800 billion years of working on farms.
26
101055
5130
作為約八千億年 應用喺農場度
01:46
Across your lifetimes, you spend 1.5 billion years having sex
27
106561
4629
總結你嘅生命 用咗 15 億年喺性愛度
01:51
and another 250 million years giving birth.
28
111190
3629
同埋另外 2.5 億年用嚟生細路
01:55
In total, 20% of your existence is spent raising children,
29
115194
4213
總體嚟講,有 20% 時間 用嚟教養細路
01:59
to whom you impart a variety of cultural values
30
119407
2627
傳授佢哋不同嘅價值文化
02:02
that influence the trajectory of generations.
31
122034
2795
影響咗唔同世代嘅發展軌跡
02:04
In some lives, you shatter those cultures through invasion and imperialism.
32
124996
4087
你某啲人生置身喺帝國主義同侵略 粉碎咗一啲地方文化
02:09
In others, you suffer as your lands and loved ones are taken away.
33
129500
3796
又有啲人生好痛苦 俾人攞走你嘅土地同所愛嘅人
02:13
In over 1% of lives, you’re afflicted with malaria or smallpox,
34
133713
4588
你有多過 1% 嘅生命 受到天花或瘧疾嘅折磨
02:18
while, in others, you treat these conditions—
35
138509
2294
其餘嘅時間 你醫治呢啲傳染病
02:20
saving countless versions of yourself.
36
140803
2836
拯救無數喺唔同時間嘅你自己
02:24
In humanity’s early days, the average lifespan is fairly short.
37
144515
4463
喺人類嘅早期 平均嘅壽命好短
02:28
There are fewer lives to live,
38
148978
1627
由於你生存年月少啲
02:30
and your influence is usually limited to people physically near you.
39
150605
3795
同時你嘅影響經常限制咗 喺附近嘅人類身上
02:34
But as humans survive longer on average and Earth's population grows,
40
154567
4171
但係隨著人均壽命延長 使到地球嘅人口增加
02:38
you start to spend more time reliving the same action-packed years.
41
158863
4463
你開始花更多時間去重溫 嗰啲充滿動感嘅歲月
02:43
A full third of your existence comes after 1200 CE,
42
163451
4004
喺公元 1200 年後 人類存在三分之一嘅時間
02:47
and a quarter of it takes place after 1750.
43
167455
3253
喺公元 1750 年後 開始咗人類後四分一時間
02:51
At this point, technology and society start changing faster than ever.
44
171125
4171
嗰陣時,科技同社會 開始咗歷來最快嘅轉變
02:55
You invent steam engines, configure factories, and generate electricity,
45
175546
4588
你發明咗蒸汽機 開始咗配置工廠同生產電力
03:00
which power the daily machinery of all of your later lives.
46
180134
3629
電力推動你將來 喺日常生活嘅機械運作
03:04
You live through revolutions in science, the deadliest wars in history,
47
184388
4380
你嘅生命穿越喺科學革命 歷史上最殘酷嘅戰爭
03:08
and dramatic environmental destruction.
48
188768
2377
同埋巨大嘅環境傷害時期
03:11
On average, each new life lasts longer,
49
191437
2753
普遍嚟講新生命 比之前都長命啲
03:14
but the pace of your existence keeps accelerating.
50
194190
2878
但係你生命嘅節奏不斷噉加速
03:17
Conversations that previously took months to unfold now happen in minutes.
51
197235

03:22

52
202073

03:27
You enjoy luxuries you never could have sampled before,
53
207203
3128
你享受之前想像唔到
03:30
even in your past lives as kings and queens.
54
210331
3045
甚至比貴為皇帝同皇后 更奢華嘅生活
03:34
After living over 100 billion lives,
55
214669
3503
活過咗一千億次生命之後
03:38
you're finally reborn as the youngest person alive today.
56
218172
3545
你最終重生成為而家 最年青嘅一代
03:41
But despite living through 300,000 years of human history,
57
221884
3420
但係即使你經歷咗 三十萬年嘅人類歷史
03:45
your actions have more impact today than 99% of your past lives.
58
225513
5547
你而家嘅行為影響 遠遠超越過往 99% 人生

4505
喺最近嘅人生,你發明咗 能重寫生物基因嘅工具
04:11
permanently altering their future generations.
64
251414
2669
可永遠噉改變 生物嘅未來後代
04:14
And in this life, you might create even more technologies
65
254500
3003
喺呢次嘅人生 你可能創新更多科技
04:17
that make the world safer, kinder, and more equitable for countless future lives.
66
257503
4797
對世界無數嘅生命 更加安全、和善同埋平等
04:22

67
262967
4838
不過,一不小心,所發明嘅嘢 好容易就會釀成大災難
身處喺核武器 實驗室洩漏同氣候變化
04:28
Between nuclear weapons, lab leaks, climate change,
68

and other existential threats,

同其他生存嘅威脅

humanity's risk of inducing our own extinction has never been higher.
70
272810

04:37
In this fast-paced, interconnected world,
71
277398
2336
咁快嘅節奏 同互聯互通嘅世界
04:39
it’s frighteningly easy to undo all of humanity’s progress,
72
279859
3628
好令人恐慌嘅係 摧毀咗人類所有嘅進展
04:43
or potentially, cut short all your possible futures.
73
283487
3295
或者係潛在縮短咗 所有可能嘅未來
