The Guardian has an interesting article on sex robots. Doctor Aimee van Wynsberghe points out that sex robots both offers possibilities and risks: on one hand this emerging technology could help certain people (elderly or disabled people) to get sexual satisfaction, but on the other hand there is the risk of increased objectification of women.
The latter is reason for some the argue for a total ban on sex robots. But the proponents of sex robots usually responds with total denial of this risk. My problem with both positions (prohibition and unregulated legalization) is that those are primarily based on assumptions.
For instance there is the possibility that child-like robots will be available in the near future and those might be purchased by pedophiles. Some argue that this will prevent pedophiles from abusing actual children, others that it will lower the threshold to abuse children. I do not know which position is more accurate, but I would argue we should be very carefull with this.
Though child sex robots might be only a small part of the market for sex robots, the general issue of objectification of people should be taken seriously. However, I do not think (total) prohibition of sex robots is the solution, not in the least place I believe people will circumvent such ban anyway.
The problem of objectification is the attitude of people to their fellow people. What we need is to change the attitude of both men and women regarding intimate relations. We need, as a society, to give our children proper relationship education and to teach them to respect other people and their (sexual) wishes.
