Some Swedish feminists want
to ban
sex robots lest they influence men to want subservient females.
That would be a tyrannical thought-control regime.
I don't have a high opinion of hypothetical sex robots designed for
subservience. I do not want my lovers/sweethearts to be subservient;
if a robot is less than a person, it would hardly be a substitute for
a lover that is a person.
However, I can see one good use for a sex robot: to teach men how to
be good lovers and companions. This would mean programming the robot
for teaching, rather than for subservience. It could help
inexperienced men overcome their fear of making a horrible mistake and
being rejected for it, and learn to be considerate and pleasing to a
lover; also learn how to pick up on what a lover does or doesn't feel
and want.
After this education, they could have good relationships with human
women.
