The World in 100 Years FULL EPISODE | Science Fiction Documentary

A speculative documentary imagining 2126: climate-adapted cities, AI integration into work and life, life expectancy over 120, and new inequalities.

Key Takeaways

  • Technological and climate adaptation transforms cities, nature and human life, but does not eliminate inequality.
  • Abundant energy can increase overall consumption rather than reduce environmental pressure.
  • The central governance challenge of AI is accountability and control, not just capability.
  • The future is presented as a constructed outcome shaped by present-day choices.

What the video covers

  • Set in the year 2126, the documentary imagines a world reshaped by a century of climate change and technological transformation.
  • Coastal cities like Miami, Amsterdam and Shanghai exist as hybrid structures, part submerged and part elevated, protected by artificial coral barriers and intelligent seawalls.
  • The Sahara has been partially greened through reforestation projects, some carried out by autonomous AI systems, creating green corridors across North Africa.
  • Global temperatures rose 2.4°C above pre-industrial levels before being stabilized mid-century; natural spaces are protected under the fictional Stockholm II Treaty of 2071.
  • Cities have become three-layer structures (underground infrastructure, surface living space, and elevated aerial platforms), with buildings that purify air and generate much of their own energy.
  • Energy has become cheap and abundant after a 2089 breakthrough, yet total consumption is five times higher than in 2026, illustrating a rebound paradox.
  • AI has integrated into nearly every profession, absorbing or redefining roles, raising questions about who controls and is accountable for AI systems.
  • Average life expectancy in advanced health systems exceeds 120 years, enabled by genome editing and related medical advances.
  • The documentary emphasizes that the future did not eliminate inequality but redesigned it, with lagging zones left behind by the technological transition.
  • Themes include Martian-born generations, neural memory archives, and the framing that the future is not a utopia but is being built by the viewer.

Answers

Questions about this video

What is the video's central premise?

It speculates on how the world might look in the year 2126 after a century of climate change, technological advances and social transformation. It is presented as a science fiction documentary rather than a prediction grounded in fact.

How does the video describe the impact of AI on work?

The video says AI has absorbed or redefined many professions, from drivers and accountants to radiologists and lawyers. It argues the key question is not whether AI can do the work but who controls it and who is accountable.

Does the video portray the future as a utopia?

No. It explicitly states the 2126 world is not a utopia, noting that technological progress has redesigned inequality rather than eliminating it, with some neighborhoods left behind by the transition.

Speaker A
Only 100 years have passed. Just 100 years, and yet the world you know today, the cities, the jobs, the countries, even the concept of what it means to be human, has changed in ways that no one in the 21st century was fully able to anticipate.
00:31
Speaker A
fully able to anticipate. We did not travel to the year 4025. We did not cross galaxies.
00:45
Speaker A
We did not travel to the year 4025. We did not cross galaxies. We are not silicon gods. But neither are we what we once were.
01:00
Speaker A
And this is the real world. [music] In 2126, the question that haunted the 21st century finally [music] has an answer.
02:34
Speaker A
The year is 2126. And this is the real world.
02:50
Speaker A
What followed was not a recovery, but a permanent adaptation. [music] Coastal cities such as Miami, Amsterdam, [music] and Shanghai now exist as hybrid versions of themselves. Part submerged, [music] part elevated.
03:11
Speaker A
In 2126, the question that haunted the 21st century finally has an answer.
03:28
Speaker A
The maps have changed. The Sahara is no longer completely [music] arid. Decades of massive reforestation projects, some carried out by autonomous artificial intelligences, have created green corridors stretching [music] across North Africa.
03:47
Speaker A
Earth survived. But not without a cost. Global temperatures rose 2.4° above pre-industrial levels before humanity managed to stabilize them in the middle of the century.
04:06
Speaker A
Humanity [music] did not save the planet it knew. It created a new one. And on this new [music] planet, the relationship between people and nature is radically different. Natural spaces are protected by international law under the Stockholm II Treaty signed in 2071.
04:32
Speaker A
What followed was not a recovery, but a permanent adaptation. Coastal cities such as Miami, Amsterdam, and Shanghai now exist as hybrid versions of themselves. Part submerged, part elevated.
04:51
Speaker A
[music] The cities of 2126 do not resemble the science fiction visions of the 20th century.
05:15
Speaker A
They feature artificial coral barriers, intelligent seawalls, and floating neighborhoods designed by climate engineers who, back in 2025, were still graduate students.
05:27
Speaker A
The megacities of [music] the 21st century, Mexico City, Lagos, Tokyo, Karachi, continued to grow. [music] But they grew upward and downward.
05:38
Speaker A
The maps have changed. The Sahara is no longer completely arid. Decades of massive reforestation projects, some carried out by autonomous artificial intelligences, have created green corridors stretching across North Africa.
05:50
Speaker A
A surface layer where people live, walk, and breathe. And an elevated layer of aerial platforms interconnected [music] by walkways and personal transportation capsules.
06:06
Speaker A
Meanwhile, regions that were once temperate, parts of Southern Europe, Central America, and Southeast Asia now struggle with cyclical droughts and summers that regularly exceed 50° C.
06:29
Speaker A
In the most advanced cities of East Asia and Northern Europe, moving around the city is free. It is a public service like water.
06:47
Speaker A
Humanity did not save the planet it knew. It created a new one. And on this new planet, the relationship between people and nature is radically different. Natural spaces are protected by international law under the Stockholm II Treaty signed in 2071.
07:01
Speaker A
Buildings literally breathe. They purify the air, regulate their own temperature, and generate part of the energy they consume.
07:13
Speaker A
Exploiting an ecosystem without certified compensation is a crime prosecuted by the International Climate Tribunal, an institution that did not yet exist in 2026, but today holds more real power than many governments.
07:37
Speaker A
But not everything shines equally because alongside these engineering marvels, there are the lagging zones, neighborhoods where the technological transition never arrived or arrived too late and too poorly.
07:55
Speaker A
The cities of 2126 do not resemble the science fiction visions of the 20th century.
08:12
Speaker A
The city of the future did not eliminate inequality. It redesigned it. March 14, 2089 is a date that [music] history books in 2126 remember with the same solemnity that the 20th century reserved for the World Wars.
08:44
Speaker A
They are not made entirely of glass and light. They are something more complex, more organic, and more contradictory.
08:57
Speaker A
The road to that moment cost decades of political conflict, trillions in investment, the collapse of entire industries, and the rise of new ones. But, it happened.
09:26
Speaker A
The megacities of the 21st century, Mexico City, Lagos, Tokyo, Karachi, continued to grow. But they grew upward and downward.
09:46
Speaker A
[music] The promise of clean, abundant, and nearly limitless energy became reality, although later than optimistic headlines had predicted.
09:57
Speaker A
Cities are now three-layer structures. An underground layer where automated logistics, fusion energy cables, and recycled water systems circulate.
10:10
Speaker A
They are ultra-thin, nearly transparent films that can be applied to almost any surface. Facades clothing windows, with conversion [music] efficiencies exceeding 70%.
10:25
Speaker A
A surface layer where people live, walk, and breathe. And an elevated layer of aerial platforms interconnected by walkways and personal transportation capsules.
10:43
Speaker A
[music] The result is a world with cheap and abundant energy, but that abundance carries its own paradox. Humanity's [music] total energy consumption in 2126 is five times higher than it was in 2026 [music] because when energy ceases to be scarce,
11:01
Speaker A
The private automobile as we knew it disappeared from cities decades ago. Urban travel is handled by fleets of shared autonomous vehicles managed by municipal AI systems or by underground hypersonic transit networks that connect entire districts in minutes.
11:36
Speaker A
In 2126, that discussion is no longer philosophical. It is everyday life. The AIs did not take control, nor did they become perfect slaves. Something more complicated and more interesting happened. They integrated. In 2126, every person in the developed world has
12:00
Speaker A
In the most advanced cities of East Asia and Northern Europe, moving around the city is free. It is a public service like water.
12:21
Speaker A
[music] continuous learning. Some people speak with their AI more hours per day than with any human being.
12:32
Speaker A
Building facades are no longer inert. They are covered with bio facades, living panels that combine vegetation, next generation solar cells, and atmospheric sensors.
12:44
Speaker A
Drivers, accountants, call center operators translators radiologists routine contract lawyers. [music] AI absorbed them or completely redefined them.
12:58
Speaker A
Buildings literally breathe. They purify the air, regulate their own temperature, and generate part of the energy they consume.
13:05
Speaker A
AI ecosystem supervisors, cognitive experience designers, mediators between automated systems and human communities. But the great question that emerged throughout the century was not whether AI could do the work. The question was who controlled the AI. And the answer
13:26
Speaker A
A typical residential block in 2126 produces between 60 and 80% of its own energy.
13:46
Speaker A
are, in many cases, partially composed of other AIs. The chain of human accountability has become opaque, labyrinthine, and sometimes deliberately impossible to trace.
14:02
Speaker A
But not everything shines equally, because alongside these engineering marvels, there are the lagging zones, neighborhoods where the technological transition never arrived or arrived too late and too poorly.
14:32
Speaker A
The human body of 2126 is not the same as the human body of 2026.
14:39
Speaker A
Places where people still live in structures from the previous century, connected to second generation networks with limited access to services that elsewhere in the world are taken for granted.
14:49
Speaker A
Average life expectancy in countries with advanced health care access exceeds [music] 120 years. Not as an exception, as a statistical norm. [music] This became possible thanks to three overlapping revolutions.
15:07
Speaker A
The city of the future did not eliminate inequality. It redesigned it.
15:24
Speaker A
Editing the human genome to eliminate predispositions to disease [music] is now as standard as receiving a vaccine was in 2026.
15:35
Speaker A
March 14, 2089 is a date that history books in 2126 remember with the same solemnity that the 20th century reserved for the World Wars.
15:58
Speaker A
Your body in 2126 may have a partially artificial immune system. [music] The third was neural integration.
16:09
Speaker A
On that day, the last operational coal-fired power plant in the world, located in Eastern Indonesia, was permanently shut down.
16:17
Speaker A
In 2126, second and third generation neural implants enable direct interfaces between the human brain and digital networks, [music] external memory systems, and in advanced cases, direct mind-to-mind communication [music] through encrypted protocols.
16:36
Speaker A
The road to that moment cost decades of political conflict, trillions in investment, the collapse of entire industries, and the rise of new ones. But it happened.
16:49
Speaker A
There are communities all over the world, some religious, some philosophical, some simply resistant, that reject any modification of the human body beyond conventional medicine.
17:02
Speaker A
In 2126, human civilization is powered by three main sources.
17:17
Speaker A
When a chip is implanted in your brain? When you [music] edit your genes? When part of your memory exists in the cloud?
17:26
Speaker A
The first is nuclear fusion. Compact fusion reactors, whose development began in the late 21st century, are now as common as natural gas plants were in 2026.
17:53
Speaker A
[music] The political map of 2126 resembles that of 2026 in some outlines, but only in the outlines.
18:05
Speaker A
The promise of clean, abundant, and nearly limitless energy became reality, although later than optimistic headlines had predicted.
18:18
Speaker A
The first was the governance crisis of the 2030s and 2040s, when the combination of accelerated climate change, mass labor automation, and widespread disinformation overwhelmed traditional political structures.
18:35
Speaker A
The second source is third generation solar energy. The panels of 2126 bear little resemblance to the blue silicon panels that covered rooftops in 2026.
18:44
Speaker A
What emerged was a hybrid model. On one side, massive regional governance blocks. The Atlantic Union, which merged the European Union with Canada and parts of Latin America through a decades-long project.
19:01
Speaker A
They are ultra-thin, nearly transparent films that can be applied to almost any surface. Facades, clothing, windows, with conversion efficiencies exceeding 70%.
19:20
Speaker A
On the other side, non-state actors whose power rivals or exceeds that of many governments, technological consortiums, welfare corporations that manage hospitals and pension systems for hundreds of millions of people, and digital platforms that control the flow of information more effectively
19:42
Speaker A
The third is deep geothermal energy. Laser-assisted drilling, perfected in the middle of the century, allows access to the Earth's mantle heat from virtually anywhere on the planet, transforming geothermal power into a universal base load energy source.
20:05
Speaker A
conflict is fought in domains that barely existed in 2026, algorithms, climate data, biotechnology patents, and control of space transportation routes.
20:19
Speaker A
The result is a world with cheap and abundant energy, but that abundance carries its own paradox. Humanity's total energy consumption in 2126 is five times higher than it was in 2026, because when energy ceases to be scarce, the limits of consumption expand along with it.
20:37
Speaker A
conflict of the moment. One of the deepest transformations of the century was the redefinition of work.
20:50
Speaker A
In 2026, humanity had spent only a few years seriously debating what it meant to coexist with advanced artificial intelligences.
21:01
Speaker A
But for many people, it was also liberating. In 2126, most advanced economies have implemented some form of universal basic income.
21:13
Speaker A
In 2126, that discussion is no longer philosophical. It is everyday life.
21:25
Speaker A
[music] It is a floor. Enough to cover basic needs, not enough to live comfortably without doing anything else.
21:33
Speaker A
The AIs did not take control, nor did they become perfect slaves. Something more complicated and more interesting happened. They integrated.
21:46
Speaker A
The concept of retirement has changed radically. With people living to 120 years of age, nobody retires at 65.
21:56
Speaker A
In 2126, every person in the developed world has access to a highly specialized personal artificial intelligence assistant. Not the kind of rudimentary voice assistant that existed at the beginning of the 21st century, but entities capable of managing entire aspects of a person's life. Finances, health, work relationships, continuous learning. Some people speak with their AI more hours per day than with any human being.
22:11
Speaker A
Creative work, human care, personalized education, and scientific research are the activities most valued by the society of 2126, precisely because they are the areas that artificial intelligence still cannot fully replicate. Or at least, that is the story people tell. Because
22:32
Speaker A
Jobs have changed radically. Entire professions that existed in 2026 disappeared during the great labor transition of the 2030s through the 2060s.
22:40
Speaker A
And that if humans still believe we do something machines cannot do, it may simply be because we need to believe it.
23:01
Speaker A
Drivers, accountants, call center operators, translators, radiologists, routine contract lawyers. AI absorbed them or completely redefined them.
23:17
Speaker A
The technology for generating synthetic content video audio text and complete sensory simulations reached a level [music] of perfection in the second half of the 21st century that made it practically impossible for the human eye to distinguish between a real
23:35
Speaker A
What emerged in their place were roles that no one in the previous century could have described accurately.
23:58
Speaker A
In those systems, consuming unsigned content is illegal or at least heavily stigmatized socially. Others embraced conscious fragmentation, communities that simply choose which narrative they wish to live within, fully aware that other communities inhabit different narratives, and that there is no final arbiter. It is not
24:21
Speaker A
AI ecosystem supervisors, cognitive experience designers, mediators between automated systems and human communities.
24:31
Speaker A
When part of your memory can be stored in the cloud, who controls what you remember?
24:36
Speaker A
But the great question that emerged throughout the century was not whether AI could do the work. The question was who controlled the AI. And the answer turned out to be murkier than expected.
24:52
Speaker A
Mental privacy is the most debated fundamental right of 2126, the right to prevent anyone from accessing your thoughts without consent [music] is codified in the cognitive rights charter of 2094, a document many compare to the Universal Declaration of Human Rights of 1948 in
25:12
Speaker A
The major management AIs, the ones that oversee power grids, traffic flows, hospital systems, and financial markets, do not belong to any government. They belong to transnational corporate consortiums, whose boards of directors are, in many cases, partially composed of other AIs.
25:46
Speaker A
More connected than ever and lonelier than in generations. That is the central paradox of the society of 2126.
25:57
Speaker A
The chain of human accountability has become opaque, labyrinthine, and sometimes deliberately impossible to trace.
26:11
Speaker A
Language barriers are history. Real-time translators integrated into neural implants [music] make conversations between any pair of human languages fluid and instantaneous. And yet, rates of chronic loneliness reported [music] in the social well-being surveys of 2126 are higher than they were in 2026.
26:35
Speaker A
They are not our enemies, but they are not entirely our allies, either. They are simply the fabric of the world.
26:52
Speaker A
Families have been redefined. In a world where living more than a century is normal, the concept of the 20th century nuclear family feels archaic. Relationship structures are more fluid, more diverse, [music] and more difficult to categorize.
27:09
Speaker A
The human body of 2126 is not the same as the human body of 2026.
27:25
Speaker A
Mental health is the silent crisis of 2126. With more years ahead, more choices, more [music] freedom, and more stimulation than any previous generation, the percentage of people reporting a lack of purpose, existential exhaustion, [music] or chronic anxiety has only continued to
27:45
Speaker A
Not completely. Preventive medicine and biotechnology have achieved something that seemed like science fiction just a century ago.
28:14
Speaker A
It inhabits it cautiously along its nearest edges. The moon has four permanent bases. Three of them are operated by private consortiums, one Chinese-Indian, one North American, and one European.
28:30
Speaker A
Average life expectancy in countries with advanced health care access exceeds 120 years. Not as an exception, as a statistical norm.
28:37
Speaker A
The International Artemis Base, home to 340 scientists [music] from 47 countries serving 6-month rotations.
28:48
Speaker A
This became possible thanks to thr
29:02
Speaker A
Approximately 4200 people reside in three pressurized settlements beneath the surface, [music] connected by tunnels, and protected from solar radiation by artificial magnetic shields.
29:16
Speaker A
Life on Mars in 2126 [music] is not glamorous. It is austere, technical dangerous and psychologically exhausting.
29:27
Speaker A
Colonists live in confined spaces under artificial light cycles and beneath a gravity level that affects the human body in ways that are still [music] being studied.
29:38
Speaker A
Some of the children born on Mars, the first genuinely Martian generation, possess bodies [music] that are no longer fully adapted to life under Earth's gravity.
29:48
Speaker A
They are, in a biological sense, the first members [music] of a different branch of humanity.
29:55
Speaker A
And space revealed something else. As next-generation telescopes and the first interstellar probes began delivering unprecedented data about the cosmos, the question that had always lingered returned with renewed force.
30:12
Speaker A
Are we alone? In 2126, the official answer from the scientific community is probably not. There is indirect evidence, anomalies in radio signals from distant systems, orbital structures that do not fit known natural models, that keeps the possibility alive more seriously than
30:34
Speaker A
ever before. But no confirmed direct contact, no deciphered message, only clues that could mean everything or nothing. And that uncertainty is what weighs the most.
30:54
Speaker A
What is art [music] when any person can generate a symphony, a novel, or a film in a matter of minutes using artificial intelligence?
31:05
Speaker A
That question destroyed entire industries in the middle of the 21st century and then created others that nobody anticipated.
31:15
Speaker A
In 2126, culture operates in layers. There is algorithmic culture, entertainment generated, personalized, and optimized for every individual in real time.
31:29
Speaker A
Television series that adapt to your emotions while you watch them. Music that changes according to your neurological state.
31:39
Speaker A
Books that branch according to your preferences. It is omnipresent, addictive, and largely disposable. And then there is unfiltered human culture. Works created without artificial assistance, signed and certified as purely human.
31:57
Speaker A
[music] In 2126, those works possess disproportionate cultural and economic value precisely because of their rarity and imperfection.
32:08
Speaker A
Imperfections are their seal of authenticity. Human clumsiness became a luxury. [music] Museums in 2126 do not preserve only paintings or sculptures. They [music] preserve experiences.
32:24
Speaker A
Archives of collective emotions from historical moments. Shared cultural memories that can be relived first [music] hand through neural implants, allowing people to feel what an entire generation felt during the first days of a pandemic, the fall of a regime, or the
32:42
Speaker A
first sunrise on Mars. Language changed as well. Universal real-time translators eliminated communicative friction between languages, but they also began to erode linguistic diversity.
32:59
Speaker A
Many smaller languages, lacking a critical mass of young speakers, disappeared during the century. Along with them, vanished unique ways of seeing the world, conceptual nuances that no translation can ever fully recover.
33:16
Speaker A
Every language that dies takes an entire universe with it. And in 2126, those universes are still fading away.
33:45
Speaker A
The year 2126. 100 years of distance. And yet, you can already see the threads leading there.
33:59
Speaker A
The energy your city consumes today, the conversations about artificial intelligence you hear in the news, the geopolitical tensions slowly taking shape, the climate change [music] that is already transforming landscapes, the first people living with neural implants, the rockets launching toward the moon.
34:22
Speaker A
All of it leads somewhere, and that place is 2126. It is not a utopia. It never was.
34:34
Speaker A
The problems of the future are not [music] today's problems solved. They are today's problems transformed, multiplied, and moved into new territories.
34:45
Speaker A
Inequality still exists. [music] Loneliness still exists. Fear still exists. But something else exists as well.
34:56
Speaker A
The resilience of a species that [music] despite everything never stopped moving forward. A species that transformed its planet, extended its presence beyond it, and kept asking ever larger questions without abandoning the smallest ones.
35:14
Speaker A
Who are we? What are we? How far do we want to go? In 2126, those questions still have no definitive answers, just as they do today.
35:31
Speaker A
And perhaps [music] that is the only true constant of humanity. Not its answers, but its inability to stop [music] asking questions.
35:53
Speaker A
The future is not written. [clears throat] But it is already being built. By you.
36:01
Speaker A
By all of us. Right now. [music] Mhm.
