So Carissa already knows herself well enough to know she'll want children. Well, she's had longer to figure it out than Keltham. Then again, some people younger than Keltham already seem to know...
...why is he thinking that he doesn't know if he wants children? He was going to become a billionaire and have lots of children.
It's pretty obvious on reflection that it's because these children will be real.
"I was born in Default, the city you're born in when you're not born anywhere particularly interesting, because your parents don't have any particular reason to be anywhere else and so they might as well live where everybody else lives; it's the largest dath ilani city in the world, and the center of Governance is there but not in the center. I got the usual education, but with fewer persistent friendships over time with other children, because my parents moved around a lot. Conventional wisdom is that more persistent friendships are better, in childhood, but my parents basically waved it off because they thought I'd be pretty much all right even if they didn't optimize every single aspect of my childhood as hard as possible. I agree with them about that, but one still gets the impression that all of their friends were horrified. In that dath ilani way where you're privately horrified but conceal the overt signs because, first of all, you don't think that exerting more social pressure will help, and second, they can guess perfectly well that you're horrified. We had a small house-module, maybe something like a tenth or twentieth the size of the villa that got burned down."
"I'm not sure at exactly what point it became clear to them that I was a little different than the other children, but it must have definitely been apparent at the point where I got - one of the elaborate tests that children get, in dath ilan, which aren't just there to measure us, but also to provide the results for the prediction markets that say what will happen in Civilization's future - anyways, I apparently ran across a lightly injured adult who needed me to get help, and I helped him, but I wanted to be paid for helping. I think that was when my parents decided that they'd made a mistake by assortatively mating with each other to select on the quality of reserving a little more of their life for themselves, and moving a lot if they wanted to do that, even if it meant their child's life was less than perfectly optimal; I was more selfish than either of them, which doesn't always happen, in a heritage-mating setup like that one, but happens sometimes. And dath ilan - when you're different, if it's something they can live with at all, they'll do what they can to make life in Civilization easier for you, despite you being different, because everyone is different, somehow, somewhere, everyone needs exceptions. My parents did the very correct thing, then, and sort of gently tried to offer me opportunities to be more Good, if I wanted to be, but without suggesting that I couldn't still just be Evil if I wanted. They argued with me about it, and tried to argue me into being Good, but only after I started it by trying to argue them into being more Evil."
"I left home as soon as I could pass the requisite financial maturity and self-governance tests, at thirteen. I set up in a part of Default distant enough that my parents wouldn't visit me often enough to be annoying. I got a very default job - doing a thing you don't have words for, setting up high-precision processes that do things, very mundane high-precision processes though, like some business wanted a tweak made to their high-precision process for selling things," this language really is not going to do 'computer programming' without a long digression, "and put all the money I could into the craziest investments I could find that basically seemed to me like they should work, some went up, some blew up, after five years of that I was ahead of the broader market but very barely. I was hoping to - teach myself, if I kept investing like that, that I'd get good at it."
"For socialization I had a circle of friends my age writing, a kind of stuff that doesn't exist here, though I did a lot more reading and only enough writing to count, but it meant that when everyone was sitting around in a circle eating whatever people had brought in and talking about everyone's work, that I could keep up and talk about it. I picked that writing circle because their themes were, not quite 'doompunk', not quite, Evil aesthetic, more like supervillainy, but not that really - the point was that they were people who could admire people who were selfish, so long as those people were clearly fictional and they weren't out there being selfish in real life. Which, you know, beats people not even appreciating the aesthetic as an aesthetic. I thought about trying to find a circle of other more selfish people, but always decided against it, because - I didn't want to take it from being my personal identity, to a group identity, it was mine and I didn't actually want to be around five other people doing it slightly differently and have debates about that."
"Civilization really does try hard to make it possible for people who are different to, just be like that and it's fine and their lives aren't about being different. But a lot of us who are different don't want that, either, we don't just want to pass through it all unnoticed, we feel like we have something to prove, not because Civilization is telling us to prove it, but because we want to prove it anyways. And if what you want is - to be acknowledged for it, to make people admit something, to excel so much that you're above average, Civilization isn't just going to hand that to you. Not everyone can have things that not everyone can have."
