Real-World Challenges for AGI: Weather Prediction, Fusion Plasma Control, and Solving Society’s Urgent Problems

Artificial intelligence is shifting from a robot-centered fantasy toward practical tools that tackle society’s most stubborn problems. While images of autonomous machines often dominate public imagination, the most consequential advances are increasingly about using AI to understand complex systems and guide human decision-making. This article revisits core ideas from a talk delivered at the CERN Sparks! Serendipity Forum, illustrating how AI is already making meaningful contributions in weather forecasting and fusion plasma control, and why progress toward artificial general intelligence hinges on mastering both prediction and control. It also emphasizes why collaboration across disciplines is essential to confront climate change and other global challenges and how these efforts illuminate a practical pathway toward more capable AI systems.

The landscape of AI: prediction and control

Across the spectrum of AI research today, scientists routinely categorize problems into two broad but deeply interconnected classes: prediction and control. Prediction models aim to learn the behavior of a domain—such as atmospheric systems, protein folding, or economic indicators—and to forecast how those systems will evolve under varying conditions. Control models, by contrast, drive agents to perform actions within an environment to achieve specific objectives, such as optimizing energy deployment, stabilizing a fusion plasma, or mitigating the impacts of extreme weather.

These two problem spaces are not isolated silos; they are complementary engines that, when developed in tandem, push the boundaries of what is possible with AI. Prediction provides the understanding and the foresight needed to anticipate how complex systems respond to perturbations, while control translates that understanding into actions that shape outcomes. For a robust path toward AGI, both capabilities must be advanced in a way that accounts for the rich variability present in natural and social environments. This includes the unpredictable ways that viruses mutate, the evolving use and meaning of language, and the intricate dynamics involved in producing energy from fusion reactors. In short, advancing toward a general-purpose intelligence requires algorithms that can not only model the world with high fidelity but also act within it in ways that are safe, efficient, and adaptable.

Within this dual framework, several real-world domains demonstrate how progress in prediction and control can reinforce each other. A notable example comes from climate-focused research where prediction accuracy and the quality of control policies are both essential for mitigating risk and guiding emergency responses. In addition, real-world engineering challenges—such as ensuring energy reliability, maintaining system stability, and navigating harsh operating conditions—demand integrated approaches that blend predictive insight with robust, real-time control. The overarching message is clear: to move from narrow AI capabilities toward more general, capable intelligence, researchers must cultivate both the ability to forecast complex phenomena and the capacity to influence those phenomena through principled action.

Two concrete real-world domains where this dual focus is producing tangible advances are weather forecasting and plasma control for fusion energy. In weather forecasting, models that learn from historical data and capture intricate patterns are being used in new ways to generate multiple plausible scenarios for atmospheric behavior. In plasma control, reinforcement learning techniques—originally developed to handle sequential decision making in robotics and games—are being adapted to steer plasma configurations in a tokamak with unprecedented speed and precision. The following sections expand on these domains, illustrating how the integration of prediction and control underpins both immediate societal benefits and longer-term progress toward general AI systems.

Weather as a learning and decision problem

Weather is notorious for its inherent variability; even the most sophisticated models struggle to capture every nuance of atmospheric dynamics. Yet, the core insight driving modern AI approaches is that, with sufficient data and clever architectures, it is possible to infer causal relationships and generate credible scenario forecasts that inform decision-making. By leveraging large-scale historical data and generative learning techniques, researchers are developing systems that can take short windows of observational data and produce a range of plausible future states. These systems do not merely produce single-point predictions; they offer a spectrum of outcomes that reflect uncertainties and potential contingencies.

At the heart of this approach is a collaboration with meteorological institutions that curate vast repositories of observational records, radar signals, satellite imagery, and sensor readings. When a model ingests a segment of weather data—potentially just minutes or tens of minutes in duration—it can generate multiple hypothesized radar maps and weather evolutions. The practical upshot is the ability to forecast events such as heavy rainfall with improved lead times and richer information for decision makers. In the immediate term, these forecasts support emergency services in prioritizing resource deployment, allow energy grids to adapt consumption and generation patterns, and trigger flood-warning systems more effectively. In a broader sense, this line of work demonstrates how AI can transform abstract predictive accuracy into concrete actions that mitigate harm and preserve public safety.

The societal impact of accurate, dynamically generated weather forecasts is substantial. When emergency responders can anticipate rainfall intensity and duration with higher confidence, they can stage teams, pre-position equipment, and coordinate evacuations more efficiently. For energy providers, forecast-driven demand management reduces strain on infrastructure during peak periods and improves resilience against storms and related disruption. Flood management benefits from improved situational awareness, enabling more timely alerts and better allocation of limited protective resources. Taken together, these capabilities exemplify how AI-powered weather insights translate into tangible, life-saving and resource-preserving outcomes.

Beyond operational benefits, the work also highlights a broader theme in AI research: the gradual shift from single-task optimization to systems capable of reasoning about uncertainty and generating diverse hypotheses. This paradigm aligns with the aspirational goals of AGI, in which intelligent systems must reason under ambiguity, consider multiple plausible futures, and select actions that maximize robust performance across a range of conditions. As such, improvements in weather prediction are not merely domain-specific wins; they are informative tests of the kinds of generalizable learning and decision-making that underpin more ambitious AI systems.

Plasma control for fusion: AI in high-stakes physics

In parallel with meteorology, researchers are turning to plasma physics to tackle one of humanity’s most demanding energy challenges: achieving practical, clean, and abundant fusion energy. Fusion reactor performance hinges on maintaining particular plasma shapes and configurations for extended periods, a task that is exceptionally complex due to nonlinear interactions, instabilities, and the extreme environments inside a reactor. The central objective is to sustain plasma stability long enough to yield net energy gains, a milestone that has eluded scientists despite decades of intensive work.

To push past these barriers, researchers have started applying deep reinforcement learning algorithms—initially developed for robotics and autonomous systems—to the problem of plasma control. In practice, a controller is trained to manipulate magnetic fields and other actuators in response to real-time plasma state data, with the goal of keeping the plasma in desirable shapes and configurations. The resulting control system can operate at very high speeds, handling rapid changes with thousands of interactions per second. This capability enables more agile experimentation and optimization of plasma behavior, accelerating the search for stable, energy-efficient configurations.

The collaboration with world-renowned institutions such as the Swiss Plasma Center and EPFL (École polytechnique fédérale de Lausanne) is critical to this effort. By combining deep reinforcement learning with established plasma physics expertise, the project moves beyond handcrafted, rule-based control methods toward adaptive, data-driven strategies that can generalize across different reactor designs and operating regimes. The implication is clear: AI-driven plasma control could reduce the time and resource costs associated with achieving stable fusion conditions, bringing us closer to a future where fusion energy is a practical, scalable source of electricity.

This line of work also illustrates a broader methodological point central to the pursuit of AGI: the necessity of collaboration across disciplines. The most promising advances arise when AI researchers work hand in glove with domain experts who understand the intricate details of the physical systems under study. It is only through such partnerships—bridging machine learning, physics, engineering, and experimental practice—that AI can be meaningfully applied to the most challenging real-world domains. The success seen in plasma control demonstrates how AI, imbued with robust learning capabilities, can contribute to the longer-term scientific and engineering pathway toward AGI by solving core control problems in high-stakes environments.

The imperative of interdisciplinary collaboration

A recurring theme across both weather forecasting and fusion plasma control is that progress in real-world domains depends on partnerships that bridge multiple scientific and engineering cultures. AI researchers bring powerful learning methods, data-centric thinking, and optimization capabilities; domain experts provide deep theoretical understanding, practical constraints, and operational experience. The synergy is essential to identify the most promising problem formulations, to design training regimes that reflect the realities of complex systems, and to ensure that developed solutions are robust, safe, and transferable to new settings.

Interdisciplinary collaboration also helps address one of the central challenges on the path to AGI: transferring knowledge and capabilities across domains. When a reinforcement learning system learns to stabilize a plasma or predict weather patterns, the underlying algorithms must be robust to changes in context, data distributions, and physical constraints. By working with researchers who study how systems evolve, adapt, and respond to interventions in diverse environments, AI practitioners can develop more generalizable methods that are not brittle when faced with novel scenarios. The emphasis on cross-disciplinary dialogue underlines a practical truth: a world-changing technology like AGI will not emerge from a single field working in isolation but from a collaborative ecosystem where different disciplines learn from one another.

The broader lesson for researchers and policymakers is that the pursuit of AI-enabled solutions to climate and energy challenges requires institutions and collaborations that support sustained, long-term cross-pollination. This includes shared data infrastructures, standardized evaluation frameworks, and joint experimental platforms that allow teams with complementary expertise to test ideas iteratively. In addition, the social and ethical dimensions of deploying AI in critical systems demand careful governance: transparency of models, clarity about uncertainties, and safeguards against unintended consequences. When such collaborative ecosystems are in place, AI can be steered toward advances that not only yield immediate benefits in weather and energy systems but also contribute to the gradual development of more general, capable AI systems that can tackle a wider array of pressing problems.

Toward AGI: causality, learning efficiency, and transfer

As the field progresses toward artificial general intelligence, several core challenges stand out. First is causality: understanding not only correlations in data but the underlying mechanisms that produce observed phenomena. Causal reasoning is essential for robust generalization, enabling AI to anticipate how systems will respond to interventions in unfamiliar contexts. Second is learning efficiency: developing methods that learn effectively from limited data, adapt quickly to new tasks, and avoid the inefficiencies that plague purely data-hungry approaches. Third is transfer: leveraging knowledge gained in one domain to accelerate progress in different, but related, domains without starting from scratch each time.

The experiments in weather forecasting and plasma control highlight that solving these challenges requires a combination of modeling power, data availability, and carefully designed training objectives. In weather prediction, models must capture complex atmospheric dynamics and produce credible scenario forecasts under uncertainty, a demand that is tightly linked to causality and uncertainty quantification. In plasma control, the ability to transfer learned control policies across reactor configurations or operating conditions would dramatically reduce the time and cost required to optimize fusion performance. In both cases, a general algorithmic approach that can reason about cause and effect, learn from sparse data, and transfer capabilities across domains would mark meaningful progress toward AGI.

A practical takeaway from these developments is that robust AGI is unlikely to emerge from a single breakthrough in one niche. Instead, it will arise from a synthesis of advances across tasks that appear distinct but share common underlying principles: the management of uncertainty, the conditioning of actions on evolving states, and the capacity to learn, adapt, and generalize. The current work in weather forecasting and plasma control provides a blueprint for building broader, more flexible AI systems by demonstrating how to bridge predictive models with actionable control policies under real-world constraints. The more cross-domain the collaboration, the more likely researchers are to identify the shared structures and inductive biases that can underpin general-purpose intelligence.

Global challenges and the AI roadmap

Beyond responding to the immediate effects of climate change, addressing its sources remains a central objective. Fusion energy stands out as a compelling candidate for a clean, abundant, and sustainable power source if the engineering hurdles can be overcome. The roadmap to practical fusion energy is not simply about perfecting a single component; it requires integrating a suite of capabilities—advanced materials, robust plasma control, efficient energy extraction, and scalable reactor designs—into a coherent system. AI has the potential to accelerate progress across these dimensions by enabling smarter experimentation, rapid optimization, and adaptive control under uncertainty. The progress achieved with AI-driven plasma control is a clear illustration of how machine learning can contribute to system-level improvements in complex, physics-based domains.

The broader AI research program must therefore continue to cultivate algorithms that can generalize across tasks, learn efficiently from diverse data, and reason about causality and transfer. As these capabilities mature, they will empower AI to contribute to a wider range of climate- and energy-related challenges, from enhancing weather risk assessment to optimizing renewable energy integration and reducing operational costs in high-stakes environments. The goal is not merely to produce better tools for today’s problems but to cultivate a generative capability that can be applied to the unknowns of tomorrow, including new climate regimes, novel energy technologies, and emerging societal needs.

Crucially, this vision depends on sustaining a collaborative ethos that brings together machine learning researchers, physicists, engineers, environmental scientists, and policy experts. It also demands rigorous evaluation protocols that reflect real-world constraints and public-interest considerations. By organizing joint efforts around shared objectives—predictive accuracy, reliable control, safe deployment, and scalable transfer—research ecosystems can maximize the practical impact of AI while advancing the science behind AGI. The path forward is incremental and collaborative, with each domain offering lessons that can be generalized to others.

The practical implications for policy, industry, and society

The advances described here have immediate and tangible implications for policy design, industrial practice, and public welfare. Policymakers can benefit from AI-driven risk assessment and forecasting tools that improve the resilience of critical infrastructure against extreme weather events. Industries ranging from energy to transportation can leverage predictive insights and adaptive control to optimize operations, reduce waste, and bolster safety margins. In public health and emergency response, better weather predictions and fast-reacting control mechanisms enable more effective planning and resource allocation, ultimately saving lives and reducing economic disruption.

In addition to these operational benefits, the pursuit of AI-enabled solutions to climate and energy challenges carries broader social significance. By catalyzing a deeper understanding of how complex systems behave and how interventions propagate through those systems, AI research contributes to a more informed, data-driven decision-making culture. This cultural shift—where decisions are guided by robust quantitative evidence, transparent uncertainty quantification, and iterative experimentation—can enhance governance and accountability across sectors. As AI systems grow more capable, it becomes increasingly important to embed safety-by-design principles, inclusive oversight, and public engagement in their development and deployment. This ensures that the benefits of AI-enabled solutions are realized broadly and equitably, while mitigating potential risks and unintended consequences.

Moreover, the interdisciplinary collaboration that drives these advances has educational and workforce implications. Training programs must prepare the next generation of scientists and engineers to work at the intersections of machine learning, physics, and applied engineering. This includes curricula that emphasize data literacy, systems thinking, experimental design, and responsible innovation. By cultivating talent that can navigate cross-domain challenges, institutions can accelerate progress toward AGI while ensuring that the benefits are aligned with societal needs and values.

The future: a world shaped by AGI’s capabilities

As AI research continues to mature, the overarching ambition is to evolve toward artificial general intelligence—systems capable of understanding, learning, and acting across a broad spectrum of tasks with transferable competence. The road map to this goal is not a single leap but a sequence of advances that collectively broaden the scope and reliability of AI. Early milestones include the development of models that can predict complex phenomena with high fidelity, coupled with control strategies that translate that predictive understanding into safe and effective actions in real time. Achieving generality will require algorithms that can reason about causality, learn efficiently from diverse experiences, and transfer knowledge across disparate domains.

The concrete gains realized in weather forecasting and plasma control demonstrate the incremental, practical value of this approach. They show that AI can move from abstract theoretical constructs to tangible improvements in public safety, energy resilience, and scientific discovery. Each success in a specialized domain informs the design of more general techniques, and each general technique expands the potential impact across many fields. The synergy between prediction and control, between learning and deployment, and between machine intelligence and human expertise is the engine that could drive the next generation of AI systems toward broad applicability.

Crucially, the pursuit of AGI through real-world, high-stakes domains is not only about technical prowess. It is about shaping a scientific culture that embraces collaboration, transparency, and responsibility. It requires establishing norms for evaluating performance that reflect multifaceted outcomes, from accuracy and robustness to safety and societal benefit. It also means fostering international cooperation to share best practices, align on safety standards, and ensure that AI’s transformative potential benefits people worldwide. In this sense, the path toward AGI is as much a social and organizational project as it is a technical one.

Conclusion

The journey from prediction to control—bridging the gap between understanding complex systems and actively shaping their trajectories—embodies a practical and impactful route toward artificial general intelligence. AI is already demonstrating important capabilities in tackling climate-relevant challenges, notably through improved weather forecasting and innovative plasma control for fusion energy. The two-pronged emphasis on predicting how systems evolve and orchestrating actions within those systems is not just an industrial or scientific artifact; it is a foundational approach for building AI that can operate robustly in the real world.

What emerges from the work across weather, energy, and plasma physics is a compelling narrative: progress in AI is most meaningful when it is grounded in real-world relevance and nurtured by deep, interdisciplinary collaboration. The combined strength of machine learning, physics, engineering, and domain-specific expertise is essential for developing AI systems that are capable, safe, and adaptable—hallmarks of the broader journey toward AGI. As research continues to refine algorithms, expand their transferability, and embed them within responsible governance frameworks, AI will increasingly serve as a catalyst for addressing climate change, accelerating scientific discovery, and delivering practical benefits that resonate across society. The future of AI, grounded in both prediction and control, holds the promise of solving complex problems that today seem out of reach, while also revealing the deeper principles that will drive the next generation of intelligent systems.
