Can it play Doom? This biocomputer built on human brain cells just learned to shoot demons, but not everyone's convinced

• The CL1 'biological computer' has been shown playing Doom
• This is essentially 200,000 human neurons plopped on a microchip
• This brain soup has apparently learned to find and shoot enemies in the game, although skeptics are arguing about the definition of 'playing' here

Living human brain cells are capable of playing Doom, and by that, I mean a bunch of cells not inside a brain (of course, that wouldn't be much of a revelation), but in a lab — though there's still some debate about what the definition of actually 'playing' a game is here.

As posted on Reddit, this is the work of Cortical Labs, a firm that used a "multi-electrode array" to achieve this feat, which is essentially 200,000 human neurons plopped on a microchip.

This is otherwise known as the CL1 'biological computer', which is a "high-performance closed-loop system where ...
