I actually have a book called Better Never to Have Been, which I read years ago. I didn't realize there was an active movement within philosophy, though I do see it in real life very much, people opting not to have children.
Thanks for the interesting comment!
HA! The author of that book is the one being somewhat credited with starting the movement. It is really ancient, obviously, but academics like to give things new names all the time so they can feel relevant. Silly scholars.
