A Fruit Fly's Brain Learns to Pitch Stories—and Other Absurd AI Experiments
Open-source fruit fly connectome data has spawned a creative wave of humorous projects, from story generation to stock trading, raising questions about the limits of AI and what's actually possible with tiny brains.
WIRED — AI
A Drosophila brain map containing 166,000 neurons has become the foundation for an unexpected playground of creative—and sometimes pointless—AI experiments. WIRED contributor Will Knight recently unveiled PitchFly, a system that generates editorial pitches by feeding the virtual fruit fly brain popular headlines from the past year, demonstrating how biological neural maps can be repurposed for novelty applications.
How the Fruit Fly Brain Works as AI#
The connectome—a detailed wiring diagram of neural connections released by Google researchers and academic partners—maps how roughly 125 million synapses communicate. Rather than being a language model that understands words, the system learns to recognize patterns in successful stories, then remixes those patterns into novel combinations. The results range from plausible ("The Race to Reinvent Privacy Before Artificial Intelligence Breaks") to absurd ("Everyone Wants Cooking. Nobody Has Solved Donald Trump").
The approach sidesteps the scale limitations of mapping human neurology. With 86 billion neurons in the human brain, creating a complete connectome remains beyond current capabilities. Smaller organisms offer accessible alternatives for understanding biological intelligence.
A Wave of Quirky Projects#
Since the connectome became open-source in September, developers have trained the virtual fly on increasingly ridiculous tasks. Other creations include:
- A version that plays the VR rhythm game Beat Saber
- StonkFly, which makes stock trades (surprisingly profitable, despite its absurdity)
- Variants trained to play Doom, Minecraft, and Pong
- A neural model that solved Rubik's cubes and another managing virtual vehicle driving
Some projects appear to be spoofs or animations rather than genuine connectome implementations, though the genuine research tools—visualizations and neural circuit manipulation software—carry serious neuroscientific value.
Why This Matters Beyond the Joke#
The fruit fly experiments illustrate two important principles. First, specialized AI models tailored to specific tasks may prove more practical than massive language models from tech giants. Second, understanding how simpler brains encode behavior could illuminate how damage to neural circuits occurs and, eventually, how it might be repaired.
