Elon Musk believes there is a way to make humans live perpetually on earth. He said “Yes, we could download the things that we believe make ourselves so unique. Now, of course, if you’re not in that body anymore, that is definitely going to be a difference, but as far as preserving our memories, our personality, I think we could do that.” By Musk’s account, such technology will be a gradual evolution from today’s forms of computer memory.
