In 1951 author and cultural critic Philip Wylie published a novel called "The Disappearance."
According to the novel (which is science fiction/fantasy): Some unexplained cosmic "blink" splits all of humanity along gender lines and into two divergent timelines. As a result: (1) From the men's perspective, all women and girls have disappeared and (2) From the women's, all men and boys have disappeared.
Wylie images an all-male world as dystopic; an all-female world as liberated.
What is your sense of a suddenly all-male OR all-female world?
