Kara Swisher begins her new CNN series on longevity and health in a cemetery, reflecting on her father's death.

Elon Musk isn't content with electric cars, shooting people into orbit, populating Mars and building underground tunnels to solve traffic problems. His startup, Neuralink, wants to one day implant computer chips inside the human brain. In a video demonstration Friday explicitly aimed at recruiting new employees, Musk showed off a prototype of the device. Neuralink wants to build on those existing medical treatments as well as one day work on surgeries that could improve cognitive functioning, according to a Wall Street Journal article on the company's launch. That might be an easier sell than the Neuralink device, which would require recipients to agree to have the device implanted in their brain, possibly by a robot surgeon.
