Elon Musk’s Neuralink is a brain-computer interface (BCI) technology aiming to directly connect the human brain with external devices. The company’s high-speed interfaces could revolutionize how we interact with technology and treat neurological disorders. Musk has referred to this as being a “Fitbit in your skull”. Using Neuralink technology, paralyzed individuals can control devices using their thoughts, enhance cognitive abilities, and treat conditions like epilepsy and depression.
