Not the year to come, but the one that humans will experience in a quarter of a century. A risky exercisebut also very ironic which pushed the magazine Nature to take a leap to imagine the future: predictions are often wrong, but they help to understand the possible directions of change. Looking to 2050 it means going beyond the immediate political horizon and questioning how science, technology and society could transform in the coming decades. The answers are not univocal: the future appears divided between alarming scenarios and surprisingly optimistic possibilities. But in this framework, research may no longer be a human affair: “It’s time to reconsider your career options, Nature readers!” we read in the incipit of the article that opens the home page-
One of the most destabilizing elements concerns the role of artificial intelligence. According to some scholars, by 2050 the majority of scientific research could be carried out by superintelligent AI systems. Humans would continue to do science, but more like intellectual or creative activity than as the main driver of progress. Fully automated laboratories, running day and night without the presence of researchers, could greatly accelerate discoveries, especially in fields such as biotechnology. However, this prospect raises profound questions: who will control these machines? And how will the role of the scientist change?
At the same time, the climate change the great shadow remains over the future. Many models indicate that by 2040 the planet could surpass the critical threshold of 2 °C temperature increase average compared to the pre-industrial era. In 2050, therefore, the debate may no longer be about the reality of global warming, but about how to deal with its consequences. Among the most controversial options is geoengineering, such as injecting reflective particles into the atmosphere to reduce solar radiation. A solution, potentially destabilizing for climate systems and a source of geopolitical tensions, especially if adopted unilaterally by individual countries or companies.
However, there is also a more positive scenario: the possibility that the removal of carbon dioxide from the atmosphere become an economically profitable sector. Technologies capable of transforming CO₂ into fuels, materials or medicines could reduce greenhouse gases and at the same time create new industrial supply chains. In this case, the fight against climate change would not just be a cost, but an opportunity.
Looking beyond Earth, 2050 is also a key date forspace exploration. Space agencies plan missions decades in advance: we talk about robot on Mercuryio, of comet samples brought back to Earth and, of course, of Marte. However, the idea of a human mission to the red planet remains controversial. The biological risks associated with cosmic radiation and microgravity are still poorly understood and often underestimated by technological enthusiasm.
On the fundamental knowledge front, the prospects are fascinating. By 2050, new quantum technologies they could help solve cosmological puzzles such as the nature of dark matter and dark energy. Increasingly sensitive sensors, integrated into gravitational wave detectors, could open a window onto hitherto invisible objects in the Universe. Even nuclear fusion energy, promised for decades but never fully realized, could finally become an operational reality.
However, there is no shortage of external factors which – we read in the article – risk slowing down progress. The decline in public support for science, the growth of populism and the demand for immediate results could penalize basic research, which requires tempo e patience. Furthermore, data management emerges as one of the main bottlenecks: without adequate infrastructure and trust in information sharing, even the most advanced technologies risk not realizing their potential.
2050, therefore, is not a prophecy, but a mirror of present choices. Between climate crises, technological revolutions and new scientific discoveries, the future remains open. And precisely for this reason, imagining it today is a way to decide what direction we want to take.
