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.

Voice and text-based interfaces for controlling software are improving, but ensuring they interpret complex commands accurately and safely, without unintended consequences, remains unresolved. This limits how much control can be safely handed over to natural language alone.

Many critical systems, including in banking and government, still run on decades-old code that few current developers understand, and automated modernization tools remain unreliable for anything but simple cases. This leaves critical infrastructure dependent on shrinking expertise.

As AI-generated faces and voices become more realistic, some biometric security systems can potentially be fooled by convincing synthetic versions of a real person's face or voice. Strengthening these systems against this emerging threat remains an active challenge.
