Dear everyone who keeps human larvae as pets,
I am sincerely happy if you've found a way to satisfy your central values and if your children make you happy. Honestly, there are central terms for the preferences and happiness of others in my utility function. So please only read the following in light of that. I am not criticizing you for choosing to spawn, and, indeed, your kids are adorable and I like watching videos on Facebook of them playing with puppies and eating cake with their entire faces, so keep it up.
Here's what's bothering me. When I look at the walls of my friends with children, almost every post involves the kid. This is perfectly understandable. I also post almost exclusively about the things that interest me most (namely rationality, dance, and math), and of course your kid is the most important thing in the entire world. If I had a kid, I'd almost certainly think the same thing about it. I would love it more than I knew I could love, and everything else would be at least second place.
And I find that ABSOLUTELY TERRIFYING. It means that there exists a parasite that can first implant itself in the lining of my uterus, with or without my consent, and use me as an incubator before torturing me for hours or days as it extricates itself from my body.
And that's not the scary part.
It can then begin to covertly re-write the foundations of my personality, undermining my adherence to beliefs about the significance of my own happiness, the happiness of my friends, self-optimization, world-optimization, and anything whatsoever not directly necessary for its own survival. In fact, it would make sure that I'd not even hesitate to die (or kill) protecting it, regardless of whether its continued existence would most likely help or hurt the other things I (used to) care about.
From my perspective, this strikes me as a completely insane thing to desire. It's like wanting to take a pill that won't satisfy your values, but will change your values such that current circumstances already satisfy them, never mind that it means replacing yourself with SOMEONE ELSE ENTIRELY.
How the hell do people just take that in stride???
