Honestly, I’d love to see something like a micro‑drones swarm that patrols your apartment, can morph into a protective shield, and communicates with your smart home. Think tiny, autonomous robots that scan for threats, launch a soft‑projectile defense or just disperse as a cloud of non‑lethal force. It’d be like having a sci‑fi personal guardian that’s actually practical. If we get the AI and nanotech right, that could be the future of personal safety.
