Elon Musk: Humans could achieve semi-immortality by uploading consciousness into robots. Through brain-computer interfaces, we can create a mental snapshot containing memories and thought patterns, then upload it into humanoid robots. Musk believes that human death essentially stems from a pre-programmed biological process. The aging process of the human body is highly synchronized, with a unified life clock operating within. 'You won’t see your left arm aging while your right arm stays young. This high level of consistency suggests there’s a core program maintaining the synchronized operation of the whole body. If we can modify this program, humans could live much longer.'
