A lab in the Swiss town of Vevey is working on a research program that seems straight out of science fiction. Dishes no bigger than teacups hold tiny white balls of living human brain cells, called organoids. They may be the future of computing.

At FinalSpark, a company co-founded by software engineer Dr. Fred Jordan, researchers are creating what they call “wetware”—a new kind of computer made from living neurons. These “biocomputers” are grown from human stem cells and taught to respond to electric signals, much like neurons in our own brains.

“I’m going to use a neuron like a little machine,” said Jordan in an interview with the BBC. “It’s a different view of our own brain, and it makes you question what we are.”
