Full Fruit Fly Connectome With 166,700 Neurons Runs Inside Minecraft, Driving a Fly's Movement

Developer @evnsnclr reports running the complete MaleCNS v1.0 fruit fly connectome — all 166,700 neurons — inside Minecraft, with its simulated neural activity driving a fly's in-game movement. V1 is in development, with code and mod to be released soon; the build was made with help from OpenAI tooling (citing GPT-6 Astra).

Quoting Dan Jeffries argues this line of work is how true AGI arrives: instead of reverse-engineering the brain, just simulate it.
