It seems more and more plausible that one day in the future, we will be able to upload our brains to machines, and transcend our biological cocoons. When that time comes, your self will be entirely contained by data on a machine, which is to say ultimately a sequence of 0s and 1s. I've gotten ahead of technology and made this page, which contains every possible sequence of 0s and 1s. Your data file is already on there, so is the one from a child version of you, or the one from your distant ancestors. What, then, does it mean to live? Are we not all in a permanent state of "always will have been"?
