Dish of Neurons Plays Doom — Wetware Demo, Not AGI
Cortical Labs: ~200,000 human neurons on CL1 chip trained to play Doom via closed-loop electrical feedback — basic gameplay ~a week per reports. Spectacle for biological computing; power claims vs silicon are company/press. Companion to CL1 commercial launch — demo ≠ general intelligence.
“Brain cells play Doom” is irresistible copy. The proprietary discipline: treat it as a closed-loop plasticity demo on CL1, not evidence that wetware is about to eat GPUs — and keep ethics in the same paragraph as the high score.
Cortical Labs demonstrated ~200,000 human brain cells on a microchip (CL1) trained on classic Doom. Neurons from adult skin/blood samples on silicon with high-density electrodes; electrical stimulation encodes game state; spiking influences actions (move, turn, fire); closed-loop feedback drives learning — reportedly mastering basic gameplay in about a week. Power consumption described as dramatically lower than traditional AI hardware for similar tasks. Builds on DishBrain Pong work. Commercial path: shipping CL1 and Wetware as a Service via Cortical Cloud. Press: The Register (March 8), The Guardian (March 16) among others.
Claims vs checks
Demo existence and neuron count are company + press primary. “Mastering” Doom means basic gameplay competence as reported — not human-level FPS benchmarks. Efficiency comparisons are not independent METR-style evals.
Limits
- Narrow game MDP ≠ general reasoning.
- Living tissue computation raises ethical boundaries the demo does not resolve.
- Cross-read CL1 commercial file for product/pricing facts.
