Spragos

Spragos are a fictional class of programmable, modular nanomachines described in speculative fiction and theoretical discussions. They are imagined as swarm-capable agents that can connect, reconfigure, and coordinate to form tools, structures, or sensing networks without a central controller.

Etymology and naming: The term sprago is a coined neologism used by authors and designers. It does not have a stable, real-world linguistic origin, and its usage varies across works of fiction and academic speculation.

Concept and design: In most depictions, each sprago is a tiny, self-contained unit with sensing, computation, and actuation capabilities. When multiple units are nearby, they establish local communication, share objectives, and organize into larger assemblies. The behavior is typically described as emergent: complex, purposeful patterns arise from simple local rules and interactions.

Applications and roles: Spragos are used in stories to repair infrastructure, construct temporary shelters, perform dangerous environment exploration, or create adaptive devices on demand. In theoretical discussions, they serve as a framework to study swarm intelligence, programmable matter, and distributed control systems.

Ethical and practical considerations: Fiction often uses spragos to explore questions of governance, accountability, and safety in autonomous swarm technologies. Real-world analogs such as swarm robotics or programmable matter are cited as points of comparison, highlighting both potential and risk.
