"Aha. So, on [Rock], species do breed themselves, probably because catfolk and werewolves, old and widespread species, have litters of several pups. If everyone did that, there wouldn't be food for them all, and eventually they'd starve or kill each other, so it's better to restrict reproduction beforehand.
Frogolds are kind of like that and kind of not. We have lots of eggs, but most of them don't hatch, and many of the taddies don't live to metamorphosize into adults. There are two problems with this.
First, well, people say that this breeds frogolds to be scheming and miserable, and this is not true, definitely not true of the frogolds I know - but I think there's a possibility that it could become true. Or we might accidentally breed ourselves for something else, like a specific artistic taste, and that would be fine! But I don't know in advance which way it will go. It might not even be predictable. We should at least come up with some standardized tests to track the things we care about. It's enough that it's possible that we could end up in a bad state, and I think we should take the idea seriously, even though the people saying it usually follow it up with 'and that's why all frogolds are thieves and miscreants'.
Second, we kill disappointing taddies without feeling bad about it because they're supposedly not people. But I remember being a taddie and I remember thinking, at the time, that I was clearly a person. Which is harder to believe: that I have an unusually good memory of that time, or that I have an unusually good memory and also that I was unusual in being a person but most taddies aren't? The fix for this is simple and we could do it right away without arguing about any details: just don't kill taddies, and eat a few more eggs instead. This would also address the concern about taddies knowing that their life depends on keeping an adult's protection, which is the main reason to worry about breeding ourselves to be manipulative in particular, rather than some other unhappy attractor.
Anyway, it seems like all four of us might tolerate, at least better than average, populating a planet in a way other than our usual sort of reproduction, and tolerate the absence of people of the same species and the other sex. So if there's a new kind of magic prepared for us, perhaps that's what it will do: make copies of people, or bud off children, or create whole new people somehow."
