Brain-computer interfaces are now being implanted in patients

Brain-computer interface (BCI) technology is advancing, with NeuroLink having implanted its first cortical device in a patient about a year ago. This marks a significant shift from previous science fiction concepts to real-world applications. Currently, estimates suggest that fewer than a few hundred people have received NeuroLink implants. These devices connect to the cerebral cortex, allowing for the reading of neural activity and communication with external devices via Bluetooth. Experts discuss potential uses for BCIs, including enhancing communication and filtering information. Applications may extend to medicine and improving quality of life, indicating a growing interest in the technology's benefits.
