Over the summer, Elon Musk unveiled the details of his secretive startup Neuralink. Its goal, he said, is to place electrodes in our brains so we can control a computer with our thoughts. Its experiments have so far been limited to rodents and monkeys, but Neuralink builds on strides already made in medicine, where doctors have successfully placed implants into human brains to treat a variety of illnesses. This week on Decrypted, Bloomberg Technology’s Sarah McBride visits the primate lab that’s been carrying out Neuralink’s research, and meets the doctors and the patients at the forefront of this emerging field.
