I've read they are making great strides on the sex bot and if you infuse it with enough AI, you'll find people willing to buy them for sure. I'd dig up the futurama link for why this is probably bad for the species but honestly, population reduction is probably a good idea anyway and what with the direction we are going as a society, I could hardly blame a person for having a sexbot/maid/AI all tied together for the house.
It's not my thing but I could see it becoming a thing, given our gradual breakdown of social abilities in this country.
It is a bad thing, for certain. To me, the big question is "why". An AI "doll" that you not only interact with but also have sex with is a phenomenon worth investigating.
And we're scary close. Boston Dynamics already has mobile robots, Realdoll has some really lifelike silicon dolls, and some interactive AI can make a pretty good approximation of a human female, and it's only getting better. Combine all of them eventually, and what you end up with is scary good.
You can spend a lot of money for the present offerings, but here's where the "why" comes in.
While there is nothing compared to the embrace of a loving woman (assuming CIS maledom) you can spend 30K on a robot and you will save money. The robot will not file for divorce, and take your children, you will not end up living in your car when the real ex gets the house on top of the 50/50 split. And you don't have alimony, or have to liquidate your retirement plan, pay half of it to her, and all you have left is the other half, plus whatever penalty you lose on killing the retirement plan.
Some women have even tried to ban such "sex dolls", but just for males who want female dolls. There are dolls for women that are met with enthusiasm, as well as minimalist versions. And there are quite a few ladies who are in the age range when reproductive urge hits hard, but they are in the geriatric pregnancy stage, and they are freaking out.
No, this is not a good social trend, but it is what we have. Many men have simply checked out of relationships. People can call them whatever names they like, it won't bring them back.
