I don't have kids, and I'm not certain I want them, but I've gotten to where I can understand that people would rather create people instead of ideas / impact / change. This is because, in some ways, nothing ever changes. Ideas will inevitably be remixes. Impact will just be percentages, non-unique contributions to systems. Change is reversible (see e.g. US Supreme Court). But having an important part in someone's life is non-fungible.
