World Solve

Modern hearing aids remain prohibitively expensive for a large share of the global population that could benefit from them, leaving hearing loss untreated in many communities. Making this technology genuinely affordable at scale remains unresolved.

Solar panel efficiency has improved significantly, but in regions with less sunlight or higher installation costs, achieving full cost competitiveness with traditional energy remains inconsistent. Closing this gap universally remains an unresolved technical and economic challenge.

Illegal wildlife trade pushes species toward extinction while operating largely undetected across international borders. A more coordinated global tracking system could catch this trade before, not after, populations collapse.

Many real-world systems, from weather to economics, are described by nonlinear equations that resist neat, general solutions. Better methods here would improve prediction across nearly every scientific field.

As AI systems increasingly influence what billions of people see, believe, and decide, someone is effectively choosing the values baked into those systems. There's no agreed process for who that someone should be, or how they should be held accountable.

Some countries and individuals consume vastly more resources than others, and there's no broadly accepted definition of what a fair share would even look like. This makes global cooperation on resource use difficult to justify to everyone involved.

Poorer countries often struggle with currency instability that makes trade, debt repayment, and planning far harder than for wealthier nations with stronger currencies. A more stable, fairer international monetary system remains unbuilt.

When automation replaces jobs, the resulting profits mostly go to business owners and shareholders, not the workers who lost their income. A fairer system for sharing these gains remains an unsolved economic and political question.

Because clean air and water aren't priced like other resources, they're often used or polluted without any real cost attached until the damage is severe. A better way to account for their true value could change how we protect them.

A single disruption, like a factory closure or a blocked shipping route, can ripple through global supply chains and cause shortages far from the original problem. Building more resilient systems remains a major unsolved challenge.

Millions of people now earn a living through app-based gig work without the healthcare, sick leave, or retirement benefits traditional jobs offer. Extending fair protections to this growing workforce remains largely unresolved.

Companies often move production to wherever labor is cheapest, making it hard for any single country to guarantee fair wages without losing jobs to competitors elsewhere. A coordinated approach across countries remains unresolved.

As automation and AI displace routine and increasingly cognitive labor, most economies still assume most people need traditional jobs to survive and find purpose. Without a credible alternative, mass automation risks instability rather than shared benefit.

Economic and political power increasingly concentrates in fewer hands, while regulation struggles to keep pace with how quickly this happens. Left unchecked, this threatens both economic fairness and democratic balance.

Sustainable aviation fuel and electric planes exist in early forms but remain far more expensive than traditional jet fuel. Making clean flying both effective and affordable is still an open engineering and economic problem.

Billions of people still lack reliable, affordable internet, cutting them off from education, healthcare information, and economic opportunity. Closing this gap remains a matter of infrastructure cost, not lack of demand.

Achieving protocols for equitable and rapid distribution of medical countermeasures in pandemics at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Achieving solutions for managing the growing burden of mental health conditions in young populations at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Despite recognition of its importance, reliable methods for methods for reducing the transmission of antimicrobial resistance through food and environmental pathways are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Students in low-connectivity regions of Global cannot benefit from most digital learning platforms, which assume continuous internet access unavailable in their communities.
