We haven't solved how to build robotics capable of sorting complex mixed recycling streams as accurately as trained humans.

open Global / Unspecified, Global

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.

We can't yet build computer memory technology that's both as fast as current RAM and as permanent as storage drives.

open Global / Unspecified, Global

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.
