On a slightly related note, I think Matt Damon wasn't really thinking things through with his blissful solitude. I can't imagine what is involved with raising dozens or even hundreds of fucking embryos to at least the age where they can take care of themselves, let alone adulthood. Unless they just grow to adulthood like clones in a vat, can you imagine the absolute fucking nightmare of changing all those (certainly not brought on the spaceship) diapers, the constant crying, puking, pooping, peeing, and snot? One or two babies is enough for most people, how the fuck do they think two people (one if he never survived and went back to join her) and a robot are supposed to raise a new civilization from scratch?
And that's not even counting all the food, water, and shelter related shit they'd have to be taking care of at the same time. Seriously, now that I think about it more, how was that ever going to work even with four people and two robots? It isn't like you'd want to wait too long to start popping out a couple of dozen embryos because the chances of something happening to the embryos or the people goes up the longer you wait, and you can't risk dooming the entire human race because you fucked up and died by accident.
