What is the primary function of Neuralink's "Telepathy" brain implant?

In 2024, Neuralink, founded by Elon Musk, successfully implanted its brain-computer interface, "Telepathy", into human patients. The device allows individuals with paralysis to control computers and digital tools using only their thoughts.
The first user, Noland Arbaugh, a quadriplegic, was able to move a cursor and play chess mentally. According to Wikipedia and New York Post, later patients used the chip for gaming, 3D design, and even text communication through thought.
This marks a major step in restoring digital independence to people with severe disabilities — a future where the mind can replace the mouse.
