World Solve

Much of humanity's cultural knowledge lives only in memory, passed down verbally, and disappears permanently when the last person who remembers it dies. Systematic preservation efforts remain underfunded and incomplete.

Artificial lighting confuses migration patterns, hunting behavior, and reproduction cycles in many nocturnal species, yet city lighting keeps expanding with growth. A widely adopted, wildlife-friendly lighting standard remains missing.

Hiring tools, loan approval systems, and other automated decisions can unintentionally replicate historical biases present in their training data. Fully eliminating this bias while keeping systems useful remains unresolved.

Cosmic radiation gradually damages electronics, and there's no way to send a repair technician to fix something millions of miles away. More radiation-hardy systems are essential for missions lasting a decade or more.

This difficulty is exactly what keeps most modern encryption secure, since multiplying primes together is easy but reversing the process is not. If an efficient method were found, it could upend the security of the internet as we know it.

Some fish populations have been fished to the point of collapse, and even with strict conservation measures, recovery can take decades longer than demand is willing to wait. Balancing recovery with continued food needs remains unresolved.

Sustainable aviation fuel exists but remains far more expensive and limited in supply than traditional jet fuel, keeping airline adoption slow. Scaling production to meet real demand remains an unresolved industry challenge.

Mangroves protect coastlines from storms and support rich ecosystems, but they continue to be cleared for development faster than restoration efforts can replace them. Speeding up restoration while slowing clearance remains unresolved.

Salt and chemicals used to keep roads safe in winter can wash into nearby streams and lakes, harming aquatic life over time. Finding equally effective but less harmful alternatives remains an underaddressed environmental challenge.

Biodegradable packaging alternatives exist but often don't yet match the protective qualities of traditional plastic needed to keep food safe and fresh for the same duration. Closing this performance gap remains an unresolved materials science challenge.

Current exoskeleton technology can help people regain some mobility, but cost and bulkiness keep it out of reach for most who could benefit. Making this technology both affordable and comfortable for daily use remains unresolved.

Migrating decades-old databases to modern systems carries real risk of subtle data corruption or loss, and fully automated, zero-risk migration tools remain unavailable for many complex legacy systems. This keeps organizations tied to outdated, harder-to-maintain infrastructure.

Advanced filtration technology exists, but cost and infrastructure requirements keep effective solutions out of reach for many communities facing the most severe water contamination issues. Solving this affordability and deployment challenge remains urgent.

A surprising number of published scientific results can't be reproduced when other researchers try the same experiment, undermining trust in published findings. Fixing this reproducibility gap is essential to keeping science reliable.

Historic sites are being lost to conflict, flooding, and neglect faster than preservation efforts can keep up, often permanently. Cheaper, faster preservation methods could save irreplaceable pieces of human history.

Advances in medicine keep pushing life expectancy higher, but there's no consensus on whether radically extending life is actually good for individuals or society. This question becomes more urgent as anti-aging research advances.

Despite regulation added after every major crash, financial systems keep finding new ways to become unstable. We still don't have a reliable way to prevent the next one before it happens.

Rising demand keeps pushing housing costs higher in growing cities, pricing out the very workers those cities depend on. Making urban growth compatible with affordability remains an unresolved policy challenge nearly everywhere.

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.

Once elected, officials often face little real consequence for broken promises until the next vote, years later. Stronger accountability tools could make representation meaningful beyond election day.
