We can't yet build software that ages well, remaining usable and secure decades after release.
open
Global / Unspecified, Global
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.

We don't have global, interoperable digital payment systems that work equally well in every country.
open
Global / Unspecified, Global
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.

We haven't found a way to stop password breaches from happening as regularly as they do.
open
Global / Unspecified, Global
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.

We can't build affordable robots capable of doing basic household chores reliably.
open
Global / Unspecified, Global
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.

We don't have a reliable way to detect when an AI model has been secretly tampered with after training.
open
Global / Unspecified, Global
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.

Global / Unspecified, Global
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.

We can't yet build 3D printers capable of reliably printing complex electronics, not just plastic shapes.
open
Global / Unspecified, Global
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.

We don't have a good way to archive websites and online content before they disappear forever.
open
Global / Unspecified, Global
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.

We haven't created affordable brain-computer interfaces that work reliably outside a laboratory.
open
Global / Unspecified, Global
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.

We can't build search engines that reliably separate high-quality information from convincing misinformation.
open
Global / Unspecified, Global
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.

We don't have programming languages that make large software systems provably free of certain bugs.
open
Global / Unspecified, Global
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.

We haven't solved how to give every person on Earth a verifiable digital identity without a central authority controlling it.
open
Global / Unspecified, Global
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.

We haven't figured out how to keep spacecraft electronics reliable during years-long deep space missions.
open
Global / Unspecified, Global
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.

We don't have a full model explaining why the early universe expanded so much faster than expected.
open
Global / Unspecified, Global
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.

We can't yet detect small, dangerous near-Earth asteroids far enough in advance.
open
Global / Unspecified, Global
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.

We haven't confirmed exactly how the Moon originally formed.
open
Global / Unspecified, Global
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.
