AI can help people make earlier health decisions, speed up science, support farmers and educators, improve transport and digital security, coordinate crisis aid, and make services easier to use. Those benefits are not automatic: they depend on reliable systems, fair access, privacy protections, and people who can review and challenge consequential decisions.
1. Earlier, better-informed health decisions
AI can help health professionals spot patterns in medical information, support diagnosis and care, and assist with disease surveillance and outbreak response. It can also help researchers and health systems manage information and identify where attention may be needed. The World Health Organization (WHO) describes these as current areas of use, not proof that every AI tool improves care.
The human benefit is the possibility of getting useful information to clinicians and public-health teams sooner, especially when they are managing large workloads. WHO Director-General Tedros Adhanom Ghebreyesus has emphasized that digital health advances should be made universally accessible rather than becoming another source of inequity.

What keeps it people-centered: Clinicians and public-health authorities remain accountable for decisions. AI output needs appropriate human review, and tools should be assessed for safety and performance in the settings and populations where they will be used. WHO’s 2026 policy paper frames AI as augmenting—not replacing—human judgment, and calls for risk-based regulation and multidisciplinary oversight.

2. Faster scientific discovery and medicine
Scientific research often involves large datasets, repeated analyses, and expensive experiments. The Organisation for Economic Co-operation and Development (OECD) says AI can help researchers process data, reproduce experiments, lower costs, and accelerate discovery. In healthcare, related uses include supporting treatment research and drug discovery.
These capabilities can help scientists explore possibilities more efficiently, but speed is not the same as a sound result. Findings still need validation, reproducibility, and appropriate clinical testing before they can support medical decisions.
What keeps it people-centered: Researchers should be able to explain how AI contributed to a result, examine errors or bias, and independently verify important findings. The benefit is stronger when AI helps people do better science, rather than making unreviewable conclusions the basis for treatment.

3. More resilient food and climate systems
AI can help monitor crops and soil, forecast environmental effects on yields, and provide farmers and planners with more timely information. The United Nations (UN) identifies crop monitoring and climate resilience as possible applications in agriculture; the OECD also describes crop- and soil-health monitoring and yield-related environmental prediction.
Rank #2
Better information may help people plan for changing conditions or identify problems earlier. It does not guarantee higher yields, prevent losses, or make farming resilient on its own. Results depend on the quality of local data, access to tools, and whether farmers can act on the recommendations.
What keeps it people-centered: Farmers and local experts need usable information and a meaningful role in decisions. Systems should be assessed for how well they work across different crops, regions, and farming conditions—not just where data is plentiful.
4. More accessible, personalized education
Digital tools and AI can broaden access to learning materials and help adapt explanations or practice to a learner’s needs. UNESCO identifies access and personalization as potential benefits, while stressing that technology should support inclusive, human-centered education rather than dictate it.
Access to the internet is a basic constraint: UNESCO reported that about 2.6 billion people—nearly one-third of the world’s population—lacked internet access in 2024. A learning tool cannot expand opportunity for a student who cannot reliably reach it.
What keeps it people-centered: Schools need to protect student data, make technology accessible, and ensure that teachers can guide learning and address errors. UNESCO highlights transparent governance, accountability, and inclusive access as necessary conditions, not optional additions.
5. Safer, more efficient movement and digital services
AI can help identify efficient routes, support traffic and transport planning, and contribute to autonomous-vehicle systems. The OECD describes potential gains in safety, quality of life, and environmental performance. It also identifies AI uses in detecting and responding to digital-security threats.
These are potential outcomes, not guaranteed results. A route that is efficient for one group may be inaccessible to another; an automated system may create new risks; and a security tool may miss threats or flag legitimate activity. The relevant question is whether a particular system improves a measurable human outcome in its actual operating environment.

What keeps it people-centered: Compare systems on reliability, accessibility, energy use, privacy, and the availability of a responsible person or organization when something goes wrong. People affected by a consequential automated decision should have a way to seek review.
6. Faster crisis response and humanitarian aid
AI can help map crises, organize information, and support the distribution of aid. The UN identifies these as humanitarian applications and says AI may help it respond to crises and climate-induced displacement. Timelier analysis can help responders understand changing needs and coordinate limited resources.
Maps and forecasts are only as useful as the information behind them. In a crisis, data may be incomplete, outdated, or unsafe to collect; a model’s output can also miss local knowledge or the needs of people who are less visible in the data.
What keeps it people-centered: Local responders and affected communities should inform how tools are used, and people should review high-stakes choices about assistance. Data collection and sharing must not expose vulnerable people to additional risk.
7. More inclusive participation and capability
AI systems can translate between languages, recognize speech or images, automate routine analysis, and provide adaptive interfaces. These capabilities may help more people participate in education, work, and public life, including people who encounter language or access barriers. The UN describes AI as a set of methods that can enhance human capabilities; UNESCO’s guidance places inclusion and human dignity at the center of responsible use.
Best Value
That potential is not the same as universal accessibility. A speech tool may not work well for every accent or disability, and a translated message may lose important context. Whether a system helps depends on who it was designed for and how it performs for them.
What keeps it people-centered: Involve the people who will use or be affected by a system in its design and evaluation. Offer alternatives when an automated interface does not work, and make it possible to correct errors without losing access to the service.

Rapid adoption is not evidence of public benefit. Stanford HAI’s 2026 reporting says generative AI reached 53% population adoption within three years, more than 80% of U.S. high-school and college students use AI for school-related tasks, and industry produced more than 90% of notable frontier models in 2025. These figures describe adoption and development, not whether AI has improved outcomes or distributed gains fairly.

For a specific system, ask:
- Outcome: What concrete human result is supposed to improve, and how will it be measured?
- Evidence: Has the system been evaluated in the setting where it will be used, and can the result be checked independently?
- Equity and access: Who can use it, who may be left out, and does it work for different groups?
- Privacy and security: What information is collected, how is it protected, and could its use put people at risk?
- Transparency and recourse: Can people understand the system’s role, challenge an error, or reach a human decision-maker?
- Environmental cost: Are energy and other resource demands proportionate to the benefit?
- Accountability: Which person or organization is responsible when the system fails or causes harm?
These questions reflect principles found in OECD guidance, including human agency and oversight, transparency, robustness, safety, and accountability. UNESCO’s Recommendation on the Ethics of AI centers human rights, dignity, justice, inclusion, well-being, and environmental protection; UNESCO says it applies to all 194 of its member states. The UN Secretary-General has warned that without adequate safeguards, AI could deepen inequalities and digital divides, especially for vulnerable people.
