Nuclear fusion. Humans on Mars and artificial ielligence. These are just some of the developmes that may occur by mid-ceury.
According to RCO News Agency, The Roman philosopher Marcus Aurelius said that we should never let the future disturb us. But he had never discussed the state of the world in 2050 with futurist Nick Bostrom.
According to Nature, Bostrom says in an email: “There is a high probability that by 2050, all scieific research will be done by super-iellige artificial ielligence instead of human researchers.” Some people may pursue science as a hobby, but they will no longer make a useful coribution.
Nature magazine has a long history of dealing with predictions, estimates and indications about the possible direction of research in the coming decades. In particular, the magazine marked the end of the 20th ceury and the beginning of the 21st ceury with a dedicated appendix on scieific prophecy, and with a bold prediction from then-editor Philip Campbell: that by 2100, a form of life based on something other than DNA would be discovered.
Setting aside peer review and in line with Nature’s stated goal of reviewing and ierpreting curre and future scieific trends, this report takes a cautious look at the horizon of 2050. A horizon that can be accompanied by technological leaps, progress in solving the mystery of dark matter, and the expansion of human studies on an unprecedeed scale; Studies that may lead to the coainme or elimination of many diseases.
hot days
“In terms of climate change, things are going to be worse than we expect,” said Guy Brasseur, a climate modeler at the Max Planck Institute for Meteorology in Hamburg, Germany.
He says that by 2040, the world will pass the critical threshold of a 2°C increase in average temperature compared to pre-industrial times. In order to preve it, due to the inertia of the climate system, the Iergovernmeal Panel on Climate Change says that global emissions of greenhouse gases should have peaked by 2025 and then decreased dramatically. As a result, by 2050, the political coroversy about the existence of global warming is likely to decrease significaly.
Instead, the debate may be about whether to try to cool the planet; Probably by injecting shiny particles io the upper layers of the atmosphere to preve sunlight from reaching the earth’s surface. Although this method of climate engineering is not proven and has not been tested on a large scale, severe climatic consequences by 2050 may encourage an affected coury or even a company to impleme such an ierveion in the atmosphere.
Some couries may use it unilaterally, just thinking it will solve their own problem, regardless of the consequences for others, says Brasseur. This ierveion could change precipitation patterns and disrupt other aspects of the climate, perhaps even making things worse. “I think it should be banned,” says Brasseur.
Geopolitical tensions mean that forecasting the future climate uil 2050 must take io accou factors beyond the physics of the atmosphere; A topic that Brasseur and his colleagues meioned in a study in 2025. A decade ago, climate scieists welcomed global recognition of climate change with the Paris Agreeme. Today, in the United States, they have been forced to remove the term from governme reports and websites. Meanwhile, other priorities have taken its place.
He says: If we talk about climate science, people don’t wa to hear anymore, because they are more afraid of other issues. They wa food, they wa peace. All this suggests that the world in 2050 will face the prospect of an increase of 3 degrees Celsius or more by the end of the ceury.
But there is a more optimistic scenario. By 2050, removing carbon dioxide from the air could become a business opportunity, as companies find ways to reduce this greenhouse gas and make a profit.
Elina Hiltonen, a future researcher at the National Defense University in Helsinki, says: “We make differe materials from carbon dioxide; It can be plastic, fuel or medicine. But all of them are produced from air.
future shock
The deep chasm between these two possible scenarios preses a dilemma for futurists and others trying to chart the path forward and the risks beyond the next election cycle. To what exte can the future be predicted from curre trends? To what exte will disruptive eves and inveions that are now unlikely or even unimaginable shape it? And at what poi do predictions become simply ridiculous?
Richard Watson, co-author of The Children’s Book of the Future and a former futurist at Imperial College London and Cambridge University, says a systematic, ierdisciplinary study of future trends works best in the 10- to 15-year time frame.
The year 2050 is an attractive time poi and deadline for those who wa to set goals and direct investmes towards it. For example, space agencies typically plan so far in advance that it can take up to two decades for a mission to be designed, approved, built, and launched.
The European Space Agency has already asked the research community to submit ideas for 2050 projects. Proposals include an orbital aimatter detector, returning frozen samples from the icy body of a comet to Earth, and landing a rover on the surface of Mercury.
Then the question of traveling to Mars is raised. US Preside Donald Trump earlier this year reiterated NASA’s goal of sending humans to Mars before 2050, while Elon Musk claimed SpaceX could send an unmanned spacecraft as early as 2026 as part of a plan to send humans to the Red Planet in the 2030s.
The rise of cars
Any picture of the future must take io accou the coinuous growth of artificial ielligence. But at what speed?
Alex Ayad, one of the founders of Outsmart Insight, a research and foresight company in London, says: I can provide a fairly accurate picture of the state of artificial ielligence in 2027 or 2028. But I’m not sure I can talk about 2030 with confidence.
Beyond that, the picture gets much murkier. However, some in the field of artificial ielligence believe that by 2050, machine learning systems will be able to conduct Nobel Prize-winning research.
Even without the mastery of a superielligence, artificial ielligence could drastically transform the science process by 2050. According to Ayad, along with robotic experimeers, automated systems based on algorithms will seek to solve biotechnology problems around the clock in “sile laboratories.” Labs where no human is prese.
This is an example of a future shaped by technologies that enable new types of scieific research. In many cases, the knowledge that is generated leads back to the developme of better technologies; A symbiotic relationship that makes successively newer science possible.
Advances in quaum science and cosmology could also make big leaps by 2050. Juan Carlos Hidalgo, a physicist at the National Autonomous University of Mexico, says researchers are developing methods to detect very weak changes in magnetic and electric fields caused by single-electron and nuclear spins.
Using these quaum sensors in gravitational wave detectors could allow cosmologists to detect smaller objects than is currely possible, including the primordial black holes. These objects, which formed shortly after the Big Bang, may carry mass that has not yet been calculated in the universe.
These findings could help shed light on the nature of dark energy, or even dark matter, and perhaps eveually provide an alternative to the Standard Model of cosmology, Hidalgo says.
He also cautiously adds that nuclear fusion may finally reach maturity by 2050. Nuclear fusion has definitely advanced more than fifty years in the last five years.
External factors
Scieific progress of the past 75 years has been the result of widespread public support for research, but this trend may not coinue.
The promise of speed for complex problems can make it difficult for the next generation of scieists to justify the years of patie work that seem to underlie rapid advances.
Coinued pressure on public spending in sluggish economies, combined with political attacks on the value of science, may force researchers more than ever to justify the costs of their work.
This process can also upset the ever-fragile balance between basic and applied research in favor of sciences that governmes see as serving limited political goals. As populations in many couries age, governmes are likely to increase investme in medical research to treat and preve chronic diseases. But technological progress alone is not enough.
Addressing this data gap requires volueers who are willing to provide their time and health information for research without significa personal gain, and this will not happen quickly.
In an optimistic scenario, such public participation could lead to the ideification of new biomarkers for better diagnosis and treatme of psychiatric and neurological disorders.
Perspectives of life
Another way to build a scenario for 2050 is to look for “weak signals”; Ideas and technologies in the early stages that can grow in many differe directions and some of them will surprise everyone.
The first big, heavy cell phones were the weak signals of today’s smart phones.
Science-fiction writers often describe these weak signals and their impact on future society; For this reason, many futurists take this genre seriously.
The use of small, single-use drones in the Ukraine war surprised many, but was predicted in a 2016 US military exercise.
One curre weak signal that it may dominate by 2050 is the emerging field of “clitronics”: programmable materials consisting of swarms of microscopic robots that can change shape and function as needed. For example, a chair can be reprogrammed io a table.
Beyond shape-shifting furniture, advances in clitronics could shape the future of research in a wide range of areas, from materials science to making samples of diseased organs to plan and test treatmes.
And of course, science fiction stories often deal with one of the biggest questions of humanity; A question that even artificial ielligence may not be able to answer uil 2050: Are we alone in the world?
Scieists may have ideified about 100 million planets by 2050. Will any of them have signs of life in their atmosphere? Some exoplanet huers think so. An informal survey in 2019 showed that many believe that researchers in this field will win the Nobel Prize for the discovery of extraterrestrial life by 2050.
However, René Heller, an astronomer at the Max Planck Institute in Germany, is more cautious. He says: I doubt that in the next 25 years we will have both the technical power and the theoretical power required to prese these extraordinary evidences.
He expects claims to be made, but not accepted. There may be candidates, but many of them will be rejected or at least disputed.
In any case, the confirmation of the existence of extraterrestrial life can be followed by decades of debate.
