Earlier quoted context omitted.
Agreed. Saying children are not worth it is an extreme position, but saying that life is pointless without children is perhaps even more extreme. It's like saying life is pointless without a wife, or without God.
The point of all life is to reproduce. It's one of the qualifications to be considered alive. So yeah, without children, life literally loses its meaning =)
I personally have never leaned towards having children, I have friends and family with young children and I see the benefit and joy they get, but for me its never been a personal goal or desire. Maybe one day it will be and my viewpoint will change.
I consider the fact that I travel the world and experience amazing things, have tried a startup and am socially active most evenings a pretty good testament to having 'lived' as you would call it.
