Brain-on-a-Chip Learns Doom, Hinting at a New Bio-Computing Frontier
Australian researchers at Cortical Labs grew ~200,000 human brain cells on a CL1 chip, teaching them to play Doom via real-time electrical stimuli. After starting with Pong, the neurons learned to target enemies and perform goal-directed actions, demonstrating adaptive, real-time learning. The work hints at broader bio-computing applications—from drug screening to AI-like learning—though cells have about a six-month lifespan and are not intended to replace traditional AI. Power efficiency is highlighted as a potential advantage of this approach.
