🪰 Does This Fly Prove We’re In a Simulation?
FlyWire is a Princeton-led international consortium that spent five years building the first complete wiring diagram of an adult fruit fly brain — 140,000 neurons and 50 million synaptic connections, mapped neuron by neuron using electron microscopy, AI, and thousands of volunteer gamers. The resulting open-access atlas, explorable at flywire.ai, became the foundational dataset that made Eon Systems' historic whole-brain emulation possible.
