“We know if we put a chip in the brain and release electrical signals, that we can ameliorate symptoms of Parkinson's,” Johnson told The Verge in an interview late last year. (Johnson also confirmed Musk’s involvement with Neuralink.) “This has been done for spinal cord pain, obesity, anorexia… what hasn’t been done is the reading and writing of neural code.” Johnson says Kernel’s goal is to “work with the brain the same way we work with other complex biological systems like biology and genetics.”
Kernel, to its credit, is quite upfront about the years of medical research necessary to better understand the human brain and pioneer new surgery techniques, software methods, and implant devices that could make a consumer brain-computer interface a reality. The Wall Street Journal says Neuralink was founded as a medical research company in California last July, which bolsters the idea that Musk will follow a similar route as Johnson and Kernel.
To be fair, the hurdles involved in developing these devices are immense. Neuroscience researchers say we have very limited understanding about how the neurons in the human brain communicate, and our methods for collecting data on those neurons is rudimentary. Then there’s the idea of people volunteering to have electronics placed inside their heads.
“People are only going to be amenable to the idea [of an implant] if they have a very serious medical condition they might get help with,” Blake Richards, a neuroscientist and assistant professor at the University of Toronto, told The Verge in an interview earlier this year. “Most healthy individuals are uncomfortable with the idea of having a doctor crack open their skull.”
