In 2026, the year 2126 is almost impossible to imagine. A hundred years separates us from a world that would be nearly unrecognizable to someone living in 1926.
Yet people in 2026 are constantly imagining what the next century might bring.
Some visions are optimistic. Some are frightening. Some are highly technical. Others are closer to science fiction.
This article is not an attempt to decide which vision is correct. It is a record of the ideas people are discussing and developing in 2026.
The sources below are included so that future readers can see the ideas, research, projects, and predictions that existed at the time.
1. Artificial Intelligence Becomes Part of Everything
Few technologies are shaping people's ideas about the future more strongly than artificial intelligence.
In 2026, AI is already being used for writing, programming, research, image generation, education, customer service, scientific work, and countless other tasks.
The major question is what happens if these systems continue becoming more capable.
One common vision is not simply "better chatbots." It is AI becoming a general layer of infrastructure used throughout society.
People imagine AI systems that can conduct scientific research, operate businesses, teach students individually, design products, manage complicated organizations, and perform many forms of intellectual work with little human supervision.
Predictions about the timing vary dramatically. Some researchers and futurists expect extremely capable systems within decades, while others are much more cautious.
The scale of adoption is already substantial. Stanford HAI's 2026 AI Index reported that 88% of surveyed organizations said they used AI in at least one business function in 2025, while generative AI was reported in 79%. These figures describe the state of AI adoption around the beginning of this future-looking conversation; they are not predictions about 2126.
By 2126, today's AI may look primitive. Or the development of AI may have taken a direction nobody in 2026 expected.
What matters for this archive is that people living in 2026 were already imagining a world where artificial intelligence could become one of the central technologies of civilization.
2. Humans Live Beyond Earth
Another major vision of 2126 is that Earth will no longer be the only place where humans permanently live and work.
This idea is unusual because parts of it are no longer purely speculative.
NASA's current Moon-to-Mars architecture is explicitly designed around developing the capabilities needed for long-term human exploration of the Moon, Mars, and beyond.
The envisioned lunar infrastructure is surprisingly concrete. NASA describes the need for reliable power, water, landing pads, roads, construction systems, and technologies capable of extracting useful materials from the lunar surface.
That includes extracting lunar resources to produce water and oxygen, autonomous construction equipment, and infrastructure built from lunar material.
By 2126, the more ambitious versions of this idea imagine permanent lunar settlements, industrial activity in space, and human settlements on Mars.
NASA's current architecture even includes specific planning for landing humans and equipment on Mars and eventually establishing a human presence there.
Space could become an industrial environment
The vision goes beyond simply putting people on another planet.
Some people imagine that resources from the Moon and asteroids will eventually be used to build things in space.
NASA is already researching technologies for extracting resources from lunar soil, including water and other materials that could support propulsion, energy production, and life support.
Asteroid mining is another long-running idea. Proposed systems involve using robots to locate and extract water, metals, and other resources from asteroids.
3. Cities Adapt to a Changing Planet
Another major vision of the future is less about leaving Earth and more about changing the places where humans already live.
Climate change is expected to affect cities through increasing heat, flooding, sea-level rise, water stress, and changes in extreme weather.
That creates a very concrete question: What does a city built for a warmer world actually look like?
Ideas being discussed today include redesigned urban infrastructure, cooler walking routes, expanded urban agriculture, more resilient electricity networks, and buildings and neighborhoods designed around extreme heat.
Other visions are much more dramatic.
Coastal cities could require enormous flood defenses. Some areas could be elevated or redesigned around water. Other locations could eventually become too expensive or difficult to protect.
Long-term sea-level projections demonstrate why this possibility appears in future thinking. The IPCC has assessed sea-level rise continuing for centuries and millennia, with substantially larger rises possible under higher-emissions scenarios.
The city of 2126 therefore might not simply be a more technologically advanced version of today's city. It could be physically redesigned around the environmental conditions of the century.
4. Humans Live Longer and Stay Healthier
A fourth major idea is that medicine could fundamentally change aging and the length of healthy human life.
This prediction exists in several different forms.
One version is relatively conservative: better prevention, personalized medicine, improved cancer treatments, replacement organs, and therapies that allow people to remain healthy for more of their existing lifespan.
A more ambitious version imagines directly targeting the biological mechanisms of aging.
Researchers are currently studying areas including cellular reprogramming, senolytics, biological age measurements, and other approaches intended to understand or alter the aging process.
But there is significant disagreement about how far this can go. Current scientific literature does not establish that humans will routinely live for centuries.
That uncertainty is itself part of the 2026 record.
The most extreme visions of 2126 therefore imagine humans living dramatically longer lives, while more cautious visions simply expect people to remain healthy much later into old age.
5. Humans and Machines Become More Closely Connected
Another major vision concerns the boundary between people and technology.
Today, most interaction with computers still happens through screens, keyboards, mice, microphones, cameras, and touchscreens.
Future visions imagine that boundary becoming much less noticeable.
Brain-computer interfaces could allow people to control computers using neural signals. Advanced prosthetics could restore or enhance physical abilities. Augmented reality could place digital information directly into a person's view of the physical world.
In some visions, computers would respond to human intentions without requiring traditional interfaces at all.
One expert in a 2026 WSJ discussion predicted that brain-computer interfaces could eventually become as common as smartphones. Other visions are less extreme: interfaces may simply become easier, more natural, and more integrated into everyday devices.
6. Robots Become Ordinary
The future of robotics is another major part of the 2126 imagination.
Instead of robots being unusual machines found mostly in factories, people imagine them becoming ordinary parts of homes, hospitals, farms, warehouses, construction sites, and public infrastructure.
The important shift is already beginning in 2026.
Autonomous robots are operating in manufacturing, logistics, healthcare, and other real-world environments, while researchers and companies are working toward machines capable of operating in less controlled environments.
By 2126, some visions imagine humanoid robots performing household tasks, caring for elderly people, constructing buildings, farming, repairing infrastructure, and working alongside humans.
Other Ideas People in 2026 Are Imagining
The ideas above are some of the biggest recurring visions of the future. But they are far from the only ones.
Across futurism, science, technology, entertainment, and everyday conversations, people are imagining many other possibilities for 2126.
Cities built upward into enormous multifunctional structures containing homes, workplaces, entertainment, transportation, and other services.
Floating or underwater communities designed to create additional living space or adapt to environmental change.
Large underground environments designed for protection from extreme temperatures, radiation, or other environmental pressures.
Commercial fusion reactors providing large amounts of low-carbon energy.
Electricity systems dominated by solar, wind, storage, nuclear, geothermal, and other low-carbon sources.
Large solar installations in space transmitting energy back to Earth or powering infrastructure in orbit.
Robotic systems extracting water and metals from asteroids for use in space.
Cars, buses, aircraft, ships, and delivery systems operating with little or no human control.
Movies, games, music, and interactive experiences generated specifically for individual people.
Persistent digital environments becoming major places for entertainment, education, social interaction, and work.
Robots and AI managing planting, harvesting, monitoring, and other agricultural tasks.
Cultivated meat and other laboratory-produced foods becoming normal parts of everyday diets.
Plants, animals, and microorganisms deliberately designed for specific purposes.
Genetic technologies being used not only to treat disease but potentially to alter human abilities.
Extremely detailed digital records of people's lives, memories, personalities, or communication styles.
Technologies allowing information to move between brains and computers, or potentially between people, without conventional speech or text.
Automation reducing the amount of time humans need to spend working.
Automation making many physical goods and services extremely inexpensive or abundant.
Robots and 3D-printing systems constructing homes, infrastructure, and eventually entire settlements.
Humans deliberately designing or rebuilding ecosystems to maintain biodiversity and environmental stability.
These are not predictions from 2126. They are predictions from 2026.
A Snapshot of 2026
The future imagined by people in 2026 is shaped by the technology, problems, discoveries, fears, and ambitions of the time.
We imagine AI becoming more capable because AI is rapidly becoming more capable around us.
We imagine cities adapting to climate change because climate change is already affecting the way cities are planned.
We imagine humans living in space because governments and private companies are actively working toward expanding human activity beyond Earth.
We imagine longer lives because scientists are studying aging.
We imagine robots everywhere because robots are already moving from controlled industrial environments into the physical world around us.
In 2126, some of these ideas may seem obvious. Others may seem completely strange. Some may have happened almost exactly as imagined. Others may have disappeared from human memory.
But that is not what this archive is trying to judge.
This is simply a record of what people in 2026 could imagine.
This is what we thought the future might look like.
