it’s crazy how many lineages are just gonna die in the coming century. it used to be that you could anticipate more grandchildren than children, but that expectation will soon invert. i’m one of 5 kids and it looks plausible that only 2 of us will ever have children. i have childless friends with multiple siblings who also don’t want kids. imagine having 3 kids and never getting a single grandchild. the stuff of nightmares.
