The field of brain-computer interfaces is quickly advancing. Elon Musk’s brain implant company, Neuralink, received approval from the Food and Drug Administration last month to begin to test brain implants in humans. Its rival company, Paradromics, is even further along in the process. Neurotechnology could be revolutionary for people with severe paralysis, amyotrophic lateral sclerosis or other disabilities that affect communication. But Sara Goering, a philosophy professor at the University of Washington, says it comes with ethical concerns. Marketplace’s Meghan McCarty Carino spoke with Goering about those concerns, which include the potential monetization of information gleaned from a person’s cognitive core.
