The genetic basis of sexual reproduction means that over a long enough time span the people who are happy not having kids become irrelevant because they no longer exist.
I find this hand-wavy "I am smart and you are dumb" argument to be lazy and too common on HN. What if I told you I've taken intro to evolution? What if I told you I'm an expert in human evolution? What would you have to say then?
I would be very surprised if a paleoanthropologist said that individual selection was the only thing that mattered. A geneticist maybe, but I'd look at them funny. The only ones I can imagine saying that earnestly are all like 60+ years old.
I'd say you should like a bullshit artist, because you are just making assertions rather than providing people with information that supports your assertions (based on this whole sub-thread).
So? They lived happy lives, that's all that matters. We're all irrelevant eventually due to death. Over a long enough time period, the Earth is cooked by the Sun and this all is gone. Enjoy the ride, in a century you'll be long forgotten.
