World Solve

Coding education often depends on expensive devices, reliable internet, and trained teachers, none of which are guaranteed in poorer school systems. Closing this gap could open technology careers to far more young people.

Faster memory tends to be far more expensive, forcing constant trade-offs in computer design between speed and cost. Solving this trade-off could make faster computing broadly accessible.

Even advanced AI systems sometimes generate plausible-sounding but incorrect answers, and users often can't tell the difference without checking elsewhere. A dependable way to prevent this remains unsolved.

Satellite internet can reach remote areas traditional cables can't, but current pricing puts it out of reach for many of the people who need it most. Bringing the cost down could close a major digital divide.

Personal information is scattered across emails, cloud drives, apps, and devices, with no single reliable way to search across all of it. A unified, private personal search tool remains unbuilt.

Modern prosthetic limbs can restore some movement, but most still can't let a person genuinely feel what they're touching. Restoring sensory feedback affordably remains a major unsolved bioengineering problem.

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.

Old software often becomes unusable as operating systems and hardware change around it, forcing costly rewrites or abandonment. Designing for genuine long-term durability is rarely prioritized.

Sending money internationally is often slow, expensive, or restricted depending on where you live, despite living in a supposedly connected digital economy. A truly borderless payment system remains unbuilt.

Data breaches exposing millions of passwords happen with striking regularity, despite widespread awareness of the problem. A more fundamentally secure approach to authentication is still needed.

Despite decades of robotics research, folding laundry or loading a dishwasher remains far harder for robots than tasks like chess or driving. Everyday physical tasks turn out to be a much harder problem than expected.

Once deployed, a model could be subtly altered or poisoned without obvious signs, potentially changing its behavior in harmful ways. There's no simple, universal way yet to verify a model is exactly as it was originally trained.

Many people experience nausea, eye strain, or discomfort after even short VR sessions, limiting its use for work or long entertainment sessions. A truly comfortable headset remains an unsolved hardware and software challenge.

3D printing has transformed prototyping, but printing functional circuits and electronics remains unreliable and limited. Solving this could make custom electronics production dramatically faster and cheaper.

Countless websites, articles, and pages vanish permanently when companies shut down or servers go offline. Without better and more complete web archiving, we risk losing large chunks of internet history.

Early brain-computer interfaces show promise for people with paralysis, but they remain expensive, invasive, or unreliable outside controlled lab settings. Making them practical for everyday use is still unsolved.

Search results are ranked mostly by popularity and relevance signals, not by actual accuracy, letting false but engaging content rise to the top. A better system needs to weigh truthfulness, not just engagement.

Even experienced teams regularly introduce bugs into complex software, some of which cause expensive failures. Languages or tools that can mathematically guarantee certain classes of bugs can't exist would be a major step forward.

Billions of people still lack any formal digital identity, cutting them off from banking, healthcare, and government services. A decentralized system could include everyone without handing control to one entity.

Scammers constantly find new ways around call-blocking systems, and phone networks still let large volumes of fraudulent calls through. A truly effective, adaptive solution remains elusive.
