I'll tell you something, if these robots end up being HALF as good as they are trying to design them to be... we are going to see a huge social structure change.
One day women are going to realize that a machine can probably do anything she can do, and probably better, and that advocating for useless, cherry-picking, social changes is just another way to get yourself stuck at home with a army of cats to keep you company. When these sex robots finally get made, you're gonna see a lot of single feminists walking around, trying to find rape victims to support when they suddenly drop off.
Meanwhile everyday men won't be prowling around as much looking for real girlfriends when they have a machine that can do exactly what you program it too. I don't think men are rapists by nature so much as some are rapists by choice. People choose to be terrible, not because the opportunity is there, but because they simply are terrible.
Luckily I'm sure they'll have a robotic man and woman for feminists too, which in truth is all they've really wanted to begin with.
