By 2070, Earth will likely face significantly hotter temperatures, impacting agriculture and forcing mass migrations, with many cities experiencing extreme heat and new climate zones, while technologically, advancements in AI, robotics, clean energy (solar/wind), and medicine (cancer cures, genetic therapies) could transform urban life, automation, and human health, creating a mix of challenging climate impacts and potentially wondrous technological solutions, though access to these benefits may be unequal.
By 2070, we'll see **smart cities** where AI plays a big role in running everything. AI will control traffic lights to reduce jams, self-driving cars will move safely, and public transport will be super efficient. AI will also help with managing waste and using energy, making cities greener.
An analysis from the Wittgenstein Center predicts global population to peak in 2070 at 9.4 billion and then decline to 9.0 billion in 2100.
Some optimistically believe humans will eventually live to be 1,000 years old, and a team of Dutch researchers have suggested that by the year 2070, human lifespans could increase to 125 years. However, other researchers believe we've hit a limit of sorts when it comes to our natural lifespans.
And by the year 2075 the growth rate will reach almost 0%, meaning the human population will no longer expand any further. This will also lead to slowing economic growth as we approach 2075. This also indicates that we might see the world economy shrinking during the last few decades of this century.
China, India, and the United States will emerge as the world's three largest economies in 2050, with a total real U.S. dollar GDP of 70 percent more than the GDP of all the other G20 countries combined. In China and India alone, GDP is predicted to increase by nearly $60 trillion, the current size of the world economy.
Which jobs will disappear by 2040? The development of AI and robotics could lead to a decline in labor-intensive jobs by 2040, including machine assemblers, postal workers, and even agricultural laborers.
Potential anthropogenic causes of human extinction include global thermonuclear war, deployment of a highly effective biological weapon, ecological collapse, runaway artificial intelligence, runaway nanotechnology (such as a grey goo scenario), overpopulation and increased consumption causing resource depletion and a ...
However, Venki Ramakrishnan, author of Why We Die: The New Science of Aging and the Quest for Immortality, believes humans won't live much further than 110 and we've only got this far thanks to improvements in public health and medical advances in treating age-related conditions, rather than any advances in longevity.
No, no one has ever lived to be 200 years old with verified records; the oldest verified person was Jeanne Calment, who lived to 122 years and 164 days, but some scientists believe the first person to reach 200 may have already been born, given advancements in longevity research. Claims of much older ages, like Li Ching-yun (claimed 250+ years) or Peng Zu (claimed 800+ years), lack modern scientific verification.
But how long can humans last? Eventually humans will go extinct. According to the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
However, fans of Hulu will need to prepare to say goodbye to the app sometime in 2026. That's right, Disney officially acquired Hulu from Comcast in June 2025 and since then they've been slowly transferring Hulu's content over to the Disney+ app in preparation for the Hulu app to disappear entirely this year.
# 1: Coronal Mass Ejections
Yes, this can happen to humanity on Earth… it has happened before! The very source of life for humanity is, indeed, our greatest threat.
In 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
Here are some of the ways the world could be different in 2070: Artificial intelligence (AI) will be ubiquitous, playing a major role in everything from healthcare to transportation to manufacturing. AI-powered robots and machines will automate many tasks that are currently done by humans.
A landmark study shows the reversal of biological aging in humans. The researchers used oxygen therapy in a pressurized chamber to reverse aging in two key biological clocks. The study showed lengthening in the telomeres of chromosomes and a decrease in cells known to cause aging.
A powerful solar flare, solar superstorm or a solar micronova, which is a drastic and unusual decrease or increase in the Sun's power output, could have severe consequences for life on Earth. The Earth will naturally become uninhabitable due to the Sun's stellar evolution, within about a billion years.
Human history is filled with stories of people trying to cheat death. While no one has managed to defeat death yet (or if they have, they've yet to reveal themselves), people have gone to extraordinary lengths and deployed bizarre tactics to try and give themselves extra years of life or even immortality.
The direct death toll alone could amount to tens to hundreds of millions of people. Or maybe even billions. If, in an absolute worst case scenario, 99 percent of the world population would die, that would leave 80 million people alive. Meaning in terms of population we would be back to 2500 BC.
The Triassic Period (252-201 million years ago) began after Earth's worst-ever extinction event devastated life. The Permian-Triassic extinction event, also known as the Great Dying, took place roughly 252 million years ago and was one of the most significant events in the history of our planet.
Other global catastrophic risks include climate change, environmental degradation, extinction of species, famine as a result of non-equitable resource distribution, human overpopulation or underpopulation, crop failures, and non-sustainable agriculture.
There's no single #1 happiest job universally, but Firefighters consistently rank high for job satisfaction due to their sense of purpose, while Care Workers, Counsellors, Content Creators, and IT roles (Java Devs, Systems Analysts) also appear frequently on "happiest" lists for fulfillment, autonomy, or good pay/balance. Overall, jobs with meaning, helping others, nature connection, strong coworker bonds, or good work-life balance tend to be cited as happiest.
