I'm not saying everyone, everywhere, wants to fuck their robot maid, I'm saying thousands of years of patriarchy, hundreds of years of popular culture, fetishization of domestic labor roles and simple human nature will have an influence on the adoption of humanoid domestic robots that companies ignore at their peril.
Some people are Honda Civic people, only concerned with utility - that's fine, I'm the same way. But the money comes from cars designed to evoke eroticism or animal aggression. The humanoid robot in the article is, aesthetically speaking, horrifying to most people. It doesn't even have a face, it doesn't look pleasant, it doesn't invite an emotional bond, it isn't friend shaped, and that isn't what most people will want, or would spend money on, regardless of how efficient it is.
Humanoid robots will have a context within the same gender and cultural dynamics as human beings, by virtue of looking and acting human enough. People already have relationships with AI, and that will only become more normalized over time. Most people will personify and anthropomorphize humanoid robots just as much as they do AI, and this will be necessary for their popular acceptance and adoption. And yes, many people will want to fuck them, or at the very least, want them to look fuckable.
