"As an adult, you may think you've roughly mapped the continent of love and relationships. You've loved your parents, a few of your friends, eventually a significant other. You have some tentative cartography to work with from your explorations. You form ideas about what love is, its borders and boundaries. Then you have a child, look up to the sky, and suddenly understand that those bright dots in the sky are whole other galaxies."

So Jeff is implying that those who choose to never have children will never experience love, life, and the universe with the intensity and awe that parents do. Somehow I'm "missing out". Sorry, but no.
