It involves using an implant in the brain. When Blackrock co-founders Marcus Gerhardt and Florian Solzbacher were teenagers, they attended a private preparatory boarding school together in repurposed military housing in a castle near the ocean in Wales. One day teenage Gerhardt told teenage Solzbacher that he had no idea what he wanted to do with his life. Solzbacher responded with singular purpose that he knew exactly what he wanted to do. "'I want to create the connection between artificial and natural limb," he said. He went on to build his entire career around that vision, and many years later, Solzbacher contacted Gerhardt to help him start a company in Utah to do just that — create a brain-computer interface that would allow users to walk, talk, see, hear and feel again.
