166,700 fruit fly neurons are flying a drone around a bedroom right now.
One camera watches an open hand. That's the entire input. The panel in the middle is the brain itself, running live, 166,700 neurons and 25 million connections, the full reconstructed wiring of a fruit fly's head.
The camera reads the hand, the brain fires, the output becomes throttle. Open palm and it climbs. Fist and it holds. Drop the hand and it comes down.
Four propellers the size of a coin, hanging off a nervous system that used to belong to an insect.
Here's the honest part. This isn't a resurrected fly. It's a computational model built from real biological wiring, bridged to a drone the builder made themselves. What nobody wrote is the flight logic. No PID tuning, no gesture presets, no code telling it how to hold altitude. They gave the neurons somewhere to send a signal, and it found the ceiling on its own.
Eleven seconds in, it's holding altitude by itself.
The fly is dead. It's still flying.
