Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Researchers keep finding creative ways to bypass safety filters built into AI systems, and defenses often lag behind the newest bypass techniques. This cat-and-mouse dynamic remains unresolved despite constant patching.

The absence of robust, context-adapted solutions for education approaches that build the capacity of local institutions to manage climate risks creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Even advanced AI systems can confidently state things that violate obvious physical logic, like objects falling upward or liquids not filling containers. This gap shows current AI still lacks a genuine model of how the physical world works.

Modern AI models produce answers without a clear, checkable chain of reasoning, making it hard to know if a correct answer was reached for the right reasons. Verifiable reasoning is essential before AI can be trusted in high-stakes decisions.
