Dev Casts Doubt on Simulated Fly Brain: Likely 'Neurological Equivalent of a Fart,' Not Real Wiring

ShimazuSystems · x · 2026-09-06

Reacting to a model's reconstruction of a fly brain, ShimazuSystems suspects nothing is realistically wired up — the model likely made connections from measurements approximating repeated movement patterns, possibly the 'neurological equivalent of a fart.'

He argues a human could hardly decipher individual meanings without literally RL-training a fly, and that the model's thinking is probably 'fly moves left and right, so its brain must have a left/right movement.' His bar for changing his mind: native hand-rubbing behavior confirmed by visualization as real, not a hardcoded approximation.
