Putting a computer inside someone’s brain used to feel like the edge of science fiction. Today, it’s a reality. Academic and commercial groups are testing “brain-computer interface” devices to enable people with disabilities to function more independently.

In January 2024, Musk announced that Neuralink implanted its first chip in a human subject’s brain. The Conversation reached out to two scholars at the University of Washington School of Medicine — Nancy Jecker, a bioethicst, and Andrew Ko, a neurosurgeon who implants brain chip devices — for their thoughts on the ethics of this new horizon in neuroscience.
