Elon Musk recently unveils Neuralink a brain-computer interface which allow you to stream music directly to your brain, and much more interesting stuff. According to white paper credited to Musk & Neuralink the system would be use to control phones or computers, symbiosis with artificial intelligence, and allow paralyzed human to control phone. Moreover it can eliminate anxiety, anesthesia and other neurological disorder can control emotions. The Neuralink chip will be implanted into brain behind ear and can connect wirelessly to an external device, which will contain wirelessly chargeable battery with sufficient power backup capacity.
Neurosurgical Robot 
N1 sensor
As Elon musk emphasis the goal is to eventually implant device into paralyzed human, the device contain 96 threads which include 3072 electrodes per array and capable of transferring higher amount of data. The thread are 4 to 6nm in width which makes them considerably thinner than a human hair and much flexible that are less likely to damage the brain. Right now the team had developed a custom chip that is better able to read, clean up, and amplify signals from brain, which can only transmit data via a wired connection (USB-C) but ultimately the goal is to create a system that can work wirelessly that is N1 sensor. It may have a fewer neurons than current USB-based prototypes. In addition to development the threads, Nerualink’s have big advantage is machine that can automatically embeds them, scientists involved in the development mentioned in future laser beam shall be use to get through the skull, rather than drilling holes like just like lasik eye surgery. The company has also developed a neurosurgical robot to precisely implant threads, now capable of inserting six threads per minute
During Q &A at the end of presentation, Musk reveled a money has able to control a computer with its brain, He also added that ultimately he wants to achieve a symbiosis with AI as when AI get more mature human would be left behind. Hence he want to create technology that allows a merger with AI. Also some experts sees this as the development in the field of direct communication with animals
