What if the next great leap in computing wasn't made of silicon — but of living human brain cells? Reporter Greg Warner takes us inside the lab of Hon Weng Chong, an Australian computer engineer who has built a biological computer: a device that houses actual human neurons in a petri dish, teaches them to play Pong using reward and punishment, and is now being sold to medical researchers, crypto gamers, and roboticists with very big dreams. Along the way, Andy and Greg dig into what these cells might actually feel, why the path to artificial general intelligence might run through a robot's skin rather than its brain, and what it would mean to one day stick a chip of pre-programmed neurons back into a human head. It's weird, it's a little smelly, and it might be the future.
