Neuralink: Can Musk’s brain technology change the world?

Elon Musk is no stranger to bold claims – from his plans to colonise Mars to his dreams of building transport links underneath our biggest cities. This week the world’s richest man said his Neuralink division had successfully implanted its first wireless brain chip into a human.

Sticking electrodes into brain tissue is really nothing new.

In the 1960s and 70s electrical stimulation was used to trigger or suppress aggressive behaviour in cats. By the early 2000s monkeys were being trained to move a cursor around a computer screen using just their thoughts.
