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.

When an individual’s voice can be licensed for insertion into third-party speech, identity and consent become commercial assets. The challenge is preventing unauthorised or harmful use while still allowing legitimate creative or accessibility applications.

When the first person to capture an image of a cloud asserts property rights, the atmosphere itself becomes a contested resource. The problem is keeping the sky as a shared commons while still recognising legitimate creative or scientific claims on specific observations.

Smart textiles that adapt to and then lock in a wearer’s patterns can limit self-expression and create unwanted permanence. The challenge is designing garments that learn usefully without removing the wearer’s ability to change appearance or discard unwanted adaptations.

Windows that show personalized or algorithmically chosen realities fracture the common visual environment. The problem is preserving enough shared external reference for coordination, safety, and social cohesion while still allowing beneficial personalization.

When collective memory of shared events is rewritten in real time by majority vote or algorithmic consensus, no stable historical baseline remains. The problem is creating durable, independently verifiable archives that coexist with participatory updating without being overwritten.

Constant algorithmic renaming of streets undermines maps, emergency response, local knowledge, and historical continuity. The challenge is allowing dynamic naming for cultural or commercial reasons while preserving reliable addressing and navigation for residents and services.

Interactive reconstructions of dead relatives may demand ongoing inclusion in gatherings, decisions, and emotional life. The problem is setting boundaries that respect both the living family’s autonomy and any residual rights or wishes of the deceased without forcing perpetual digital presence.

Residences that rearrange themselves overnight according to algorithmic mood forecasts may increase comfort for some while creating disorientation, loss of control, or surveillance concerns for others. The challenge is balancing adaptive environments with resident agency, privacy, and predictability.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

As digital navigation layers become permanent fixtures in daily life, physical landmarks lose meaning and people lose the ability to orient themselves without screens. The challenge is creating systems or practices that preserve spatial awareness and independent wayfinding while still allowing beneficial digital tools. Solutions must work across cultures, age groups, and infrastructure levels, avoid creating new dependencies, and remain usable when networks fail.

Autonomous spacecraft may make split-second avoidance decisions using imperfect data and proprietary software. The unresolved problem is assigning responsibility, proving fault, and compensating affected parties across jurisdictions. The design must remain functional when standards, trade routes, data access, and diplomatic cooperation are unreliable. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Autonomous spacecraft may make split-second avoidance decisions using imperfect data and proprietary software. The unresolved problem is assigning responsibility, proving fault, and compensating affected parties across jurisdictions. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Genomic medicine could improve treatment while enabling insurers, employers, states, or platforms to infer sensitive traits. The challenge is ensuring people benefit from precision medicine without losing control over biological information. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Historical records increasingly exist in fragile digital formats that may outlive current software, vendors, and hardware. The unresolved problem is preserving public memory across decades of technological change. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Transport systems may be increasingly optimized by private algorithms that control routing, pricing, access, and safety. The unresolved problem is ensuring these systems improve mobility for everyone rather than only for users who can pay most. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Large quantum computers may require specialized materials, cooling systems, and high-energy facilities. Their lifecycle impact, component reuse, and end-of-life management are not yet adequately designed. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.
