This is pretty sparse on citations/evidence compared to the usual HN trending fare. Some commenters are suggesting TFA is equating declining birth rate to declining sex. I don't particularly see it, they seem to be suggesting both are declining (it doesn't typically take much unprotected sex to procreate, modulo fertility issues), but either way, that's still a veridical statement that deserves data.
