Feminists are responding precisely as expected to sex robots:
A campaign has been launched to try and ban the development of ultra-realistic sex robots.

Using sophisticated robotics to develop realistic human dolls capable of performing sex acts is "very disturbing indeed," said campaign leader Dr Kathleen Richardson. Dr Richardson believes humanoid sex robots reinforce traditional and damaging stereotypes of women.
More likely she's upset at the looming end of female influence over men. This isn't to say sex robots will have a positive effect on human society, indeed, those societies that don't ban them may well find themselves failing.
