I've also been thinking a lot about longtermism and its implication for fertility. dotsam has taken  longtermism's pro-natalist bent in a relatively happy direction, but it also has some very dark implications. Doesn't longermism imply a forced birth be a great outcome (think of those millions of future generations created!)? Doesn't it imply conservatives are right and abortion is an horrendous crime? There are real moral problems with valuing a potential life with the same amount of weight as as an actual life.
