This article is a summary of a paper by two Russian dudes that starts with explaining the ideas of Russian cosmism. Fedorov came up with the idea that to fullfull the Christian prophesy scientists would figure out the way to ressurect everyone who's ever lived, but because that's a lot of people we also need to colonise other planets for them to live there. Fedorov was a mentor to Tsiolkovsky, got him interested in space travel and rockets.
Most people here are arguing whether a computer simulation can be you, but even if it can (the idea I'm partial to), how much "you" can you get just of of recordings left by you? Seems like too sparse of dataset even if you post a lot. There was a Black Mirror episode with this exact premise. "Be right back" or something.
