I was thinking of the way technology changes even our intimate social lives - curiously through the mediation of industrial corporations. In some ways it has been at the expense of women's competitive advantage over men.
When sex was dangerous because of the risks of pregnancy and death during childbirth, and of incurable venereal diseases, women did not consent lightly. Which gave them enormous leverage in negotiating consent. Pharmaceutical corporations now provide products which abate those risks to nil. And women's corresponding leverage of refusing repeatedly without the swain soon seeking greener pastures has vanished. Women have become free, but at the cost of their leverage over men.
Women used also to bribe with prepared food. Now frozen food sellers and microwave manufacturers offer the same. Women are free from having to cook, but again at the cost of their leverage over men.
At the beginning of feminism there was the issue of competing with men, and whether women could or should. Little did they realize that in some ways their real competitors would be corporations. To whom they are losing badly.
