The following is the kind of proposal that reminds me how cool it can be to live in the 21st century.

Autonomous NanoTechnology Swarm (NASA)

The Autonomic NanoTechnology Swarm (ANTS) is a generic mission architecture consisting of miniaturized, autonomous, self-similar, reconfigurable, addressable components forming structures. The components/structures have wide spatial distribution and multi-level organization. This 'swarm' behavior is inspired by the success of social insect colonies where within their specialties, individuals outperform generalists and with sufficiently efficient social interaction and coordination, groups of specialists outperform groups of generalists.
