World Solve

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.

Homes filled with gadgets from different brands often struggle to talk to each other properly, frustrating users and limiting real automation. A shared, open standard would fix this fragmentation.

Millions of applications depend on open-source code maintained by volunteers, and a single hidden change can spread unnoticed to countless systems. A trustworthy verification system remains a major unsolved need.

These particles carry more energy than anything we can produce on Earth, and we still don't know exactly what cosmic event launches them our way. Identifying the source could reveal entirely new astrophysical processes.

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 period, known as cosmic inflation, is widely accepted as a concept but the exact physical mechanism driving it remains unproven. Confirming it would close a major gap in our understanding of the universe's first moments.

Larger asteroids are easier to spot years ahead, but smaller ones capable of serious regional damage often go undetected until they're very close. Expanding detection capability remains a quiet but serious safety gap.

The leading theory involves a massive collision with early Earth, but several details still don't perfectly match the evidence we've collected from lunar samples. A fuller explanation would clarify Earth's own early history too.
