Elon Musk’s newest venture, Neuralink, is attempting to wire brains directly to computers. The start-up’s vision is to insert thousands of tiny threads into the neurons of your brain. The other ends of the threads are attached to chips, embedded under the skin on your head and wirelessly connected to a detachable Bluetooth ‘pod’ behind your ear, enabling you to control a phone or another device with your thoughts. Sound far-fetched? The company has already successfully tested the technology in monkeys and aims to start testing it in humans later this year.
Neuralink’s brain-machine interface could potentially help people with brain and spinal cord injuries who have lost the ability to move or sense, as Musk highlighted at the company’s livestreamed launch event. Even more ambitiously, Musk said his long-term goal is “to achieve a sort of symbiosis with [artificial intelligence].” He wants to build what he calls a digital superintelligence layer to complement the parts of the brain responsible for thinking and planning (the cerebral cortex) and for emotions and memory (the limbic system). In fact, he said, “you already have this layer.” It is your phone and your laptop. But you are limited by how quickly you can process what you see, and how quickly you can type a response. The answer, Musk says, is to increase the band-width of the brain-machine interface.
Neuralink is just one of the organizations developing cutting-edge neurotechnology, although others like teams at Carnegie Mellon, Rice University, and Battelle, are not proposing drilling through people’s skulls and inserting microscopic threads into their brains, opting instead for electromagnetics, light beams, and acoustic waves.
