I don't know if it is morally acceptable. Besides, no matter what the algorithm, these things will never be human. I think the intimacy aspect of sex with your wife would be amazing. To have her respond emotionally, and to be able to genuinely love her. I feel like non sexual intimacy just being with someone, and responding to each other, and caring for each other would be beautiful. I know we can feel other people's emotions from up to 10 feet away because the nerve tissue in the heart broadcasts on an electromagnetic level. Same behind the gut feelings we have, we sense things because of nerve tissue down there. I suspect there is a quantum interface with nerve tissue, and that is how some of these things work. With a sex doll, you get a computer spitting out emulated noises. What is the point?
On the other hand, I think this highlights the consequences of promiscuity. All those roastie whores have had plenty of sex, but to get anything out of it they have to continually degrade themselves further. By the time they get to betacuxx, they have no capacity for intimacy, pair bonding or ability to enjoy sub 10" men, lol. Enjoy it girls.
