Evolving AI: They Grew a Human Brain in a Dish - Then It Started Playing DOOM!

A company in Australia is selling a computer unlike anything sitting inside a normal data center. Instead of relying entirely on silicon, it contains living human neurons grown directly on an electrode array — and those cells can actually learn. Cortical Labs first demonstrated the idea with DishBrain, where roughly 800,000 living neurons learned to play Pong through electrical feedback. That experiment eventually evolved into the CL1, a $35,000 commercial biological computer designed to let researchers deploy code directly onto living neural cells while keeping them alive for months. In this video, we explore how the CL1 works, how human neurons communicate with silicon, why biological computing could consume dramatically less energy than conventional AI, and how researchers are using brain organoids to study neurological diseases that traditional animal models struggle to replicate. We also look at UC San Diego's brain organoids, experiments aboard the International Space Station, Johns Hopkins' work on “organoid intelligence,” multi-region organoids containing millions of neurons, and the uncomfortable question this technology eventually forces us to confront: How sophisticated can a living computer become before we have to start asking whether it can experience anything at all?
This isn't science fiction anymore. Biological computing has entered the laboratory, and now it's becoming a product.
