Neuralink, a neurotech startup founded by Elon Musk, is working on implanting its skull-embedded brain chip in humans.
Brain-computer interfaces (BCIs) are being developed to facilitate direct communication between human brains and external computers for medical use cases such as helping paralyzed people communicate.
BCIs are still in their infancy, and there are ethical concerns and potential negative effects to consider, such as dependency on the devices and changes to the sense of self.
BCIs have surpassed their early sci-fi depictions and are attracting significant private and military funding for medical and non-medical uses.
