One of the most unexpected and fascinating outcomes of John Calhoun's experiments with rats is the separate class of "Beautiful Ones" which emerges as chaos and despair engulf an increasingly overcrowded rat colony that started as a utopia. These Beautiful Ones refrain from sex, and do not enter the fighting fray, instead retreating to immaculately groom themselves. The outlast the mobs, and their emergence in repeat studies is the pre-cursor to the population dwindling, eventually dying out altogether since the beautiful remaining rats never revert to fighting or reproduction.

This came immediately to mind when I read this story about the decline of sexual activity in Silicon Valley - who seem destined to form one of the last groups to be replaced by the powers of automation / globalisation.
