Musk: Humanity can achieve semi-immortality by uploading consciousness into robots. Through brain-machine interfaces, a mental snapshot containing memories and thought patterns can be created and then uploaded into humanoid robots. Musk believes that human death essentially stems from a pre-programmed biological process, where the aging process of the body is highly synchronized, and there exists a unified life clock operating within. "You won't see the left arm aging while the right arm remains young; this high level of consistency indicates that there is a core program maintaining the synchronization of the entire body. If this program can be modified, humanity could live longer."
