World Solve

3D printing excels at prototyping and small-batch production but still can't match the speed, precision, and cost-efficiency of traditional mass manufacturing for complex electronics. Closing this gap could transform how and where products are made.

Data centers placed in unconventional locations to save on cooling costs still face risks from environmental changes or accidents that traditional facilities don't. Making these systems fully resilient remains an unresolved engineering challenge.

Phone batteries degrade noticeably after a couple of years of daily charging cycles, contributing to both consumer frustration and electronic waste from early device replacement. A more durable battery technology remains commercially elusive.

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.

Drone delivery has been tested in various cities, but noise, safety concerns, and airspace regulation have kept it from becoming a mainstream, everyday urban service. Solving these combined challenges remains an ongoing barrier.

Defenses against these attacks, which flood a target with traffic to knock it offline, can sometimes inadvertently slow down real users as well while filtering out malicious requests. A cleaner separation between attack and legitimate traffic remains technically difficult.

Cameras and sensors used in security or autonomous systems still perform noticeably worse in poor visibility conditions than in daylight, creating real safety and reliability gaps. Closing this performance gap affordably remains unresolved.

Developers still occasionally and accidentally commit sensitive credentials directly into shared code repositories, creating avoidable security exposure. More robust default protections against this common mistake remain inconsistently adopted.

Laying physical fiber cable across mountains, deserts, or widely scattered rural populations is often prohibitively expensive relative to the number of people served. Finding cost-effective alternatives for these hard-to-reach areas remains unresolved.

GPS doesn't work well inside buildings, and alternative indoor positioning technologies haven't achieved the same reliability and ease of deployment needed for widespread augmented reality navigation use. Solving indoor positioning at scale remains unresolved.

Recycling facilities still rely heavily on human sorters because robotic systems struggle to reliably distinguish between similar-looking but differently recyclable materials. Improving this accuracy could significantly increase recycling efficiency worldwide.

Aircraft safety relies heavily on scheduled inspections rather than continuous, real-time structural monitoring, since affordable sensors capable of this level of detail remain limited. Expanding this kind of predictive monitoring remains an unresolved aviation challenge.

Computer memory still requires a tradeoff between speed, which loses data when powered off, and permanent storage, which is comparatively slower. A technology that fully combines both properties remains a long-sought but unresolved goal in computer engineering.

As electric vehicle adoption grows, local power grids in many areas aren't yet built to handle the sudden, concentrated demand spikes from many vehicles charging simultaneously. Upgrading this infrastructure fast enough remains an unresolved challenge.

Physical hardware used in sensitive systems can sometimes be tampered with before installation, and detecting this tampering reliably and affordably remains technically challenging. Closing this hardware security gap remains an unresolved priority.

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.

Many cities, especially in lower-income regions, lack dense, affordable air quality sensor networks capable of providing residents with accurate, real-time pollution information. Closing this monitoring gap remains an unresolved public health infrastructure challenge.

Networking equipment can potentially be intercepted and secretly modified during shipping before it ever reaches its intended destination, creating hidden long-term security risks. Building tamper-evident supply chains for this hardware remains incompletely adopted.

Fabricated recommendation letters that mimic a real professor's writing style could potentially deceive scholarship committees without direct verification. Establishing more reliable authentication remains an unresolved administrative challenge.

Fraudulent recall notices, generated to appear official, could mislead consumers into either unnecessary returns or ignoring genuine safety recalls entirely. Verifying the authenticity of recall communications quickly remains an unresolved consumer safety issue.
