Dr. Matthew MacDougall, head neurosurgeon at Neuralink, has a small RFID tag implanted in his hand that once held a cryptocurrency private key worth a few thousand dollars. His wife has one too. He calls them their version of wedding rings. This is not science fiction—it is a demonstration of what happens when a neurosurgeon who routinely operates on the human brain decides to live inside the technology he helps build.
The Brain as a Collection of Modules
MacDougall describes the brain as "a collection of functional modules duct-taped together in a bone box attached to your head." This view comes from seeing what happens when specific parts fail. He recalls a young patient with bilateral frontal lobe damage from a car accident who, after surgery, had no impulse control left. The patient pointed at his elderly recovery room nurse and made an inappropriate advance—not because he was malicious, but because the frontal lobes that normally filter impulses were gone. "That person is never going to have reasonable human behavior again," MacDougall says.
