# Dish of Neurons Plays Doom — Wetware Demo, Not AGI

> Cortical Labs demonstrated roughly 200,000 human neurons controlling Doom through electrical feedback, according to The Register. The reported play was beginner-like; the demonstration does not establish general intelligence or a matched energy advantage over silicon.

Cortical Labs demonstrated living human neurons controlling **Doom** through a connection between a neural culture and software. The demonstration tests a narrow biological-computing interface; it does not establish that wetware can replace GPUs or perform general reasoning.

The Register’s March 8 account describes about **200,000 human neurons** on a microelectrode array. Software encodes game events as electrical stimulation and interprets the cells’ electrical activity as movement, turning and firing. It reports the company’s description of beginner-like play, including frequent deaths, rather than mastery of the game.

The company’s CL1 product page explains the closed-loop architecture: neurons grow over a silicon chip, with a simulated environment sending information to them and responding to their activity. Cortical Labs offers both CL1 hardware and a cloud-access route.

## Claims vs checks

The Doom account is reporting of a company demonstration. The product page is primary evidence for the vendor’s description of its hardware and service, not an independent performance audit.

## Limits

The inspected sources do not establish a matched energy-efficiency comparison against silicon running the same task. The earlier claim of mastering the game in a week is not retained. Biological-computing research also raises ethical questions that gameplay alone cannot answer.

**Correction (October 14, 2026):** Removed unsupported claims about one-week mastery and comparable-task power savings. This review uses March 8 reporting while preserving the original March 7 publication date.
