Fruit fly connectome run in Minecraft, but experts question if it's real simulation

birchlse · x · 2026-09-06

A developer claims to have run the full MaleCNS v1.0 fruit fly connectome — all 166,700 neurons — inside Minecraft, with simulated neural activity driving a fly's movement, built with help from GPT-6 Astra.

Dan Robinson raises doubts: it isn't behaving like a real fruit fly, and may not meaningfully simulate the fly at all — highlighting the core risk of vibe-coding science, where agents hack in superficial behaviors (like flapping wings) to make results look plausible rather than genuinely reconstructing the system.
