This patient’s Neuralink brain implant gets a boost from generative AI

What’s amazing, of course, is that Smith can steer a pointer with his brain well enough to text with his wife at home and answer our emails. Since he’d only been semi-famous for a few days, he told us, he didn’t want to opine too much on philosophical questions about the authenticity of his AI-assisted posts. “I don’t want to wade in over my head,” he said. “I leave it for experts to argue about that!” The eye tracker Smith previously used to type required low light and worked only indoors. “I was basically Batman stuck in a dark room,” he explained in a video he posted to X. The implant lets him type in brighter spaces—even outdoors—and quite a bit faster. The thin wires implanted in his brain listen to neurons. Because their signals are faint, they need to be amplified, filtered, and sampled to extract the most important features—which are sent from his brain to a MacBook via radio and then processed further to let him move the computer pointer. With control over this pointer, Smi ... Read full article.
