All you need to do now, is put these waifu AI's inside the robots. And bam... women are history.
So soon, waifu bots will not just satisfy men either sexually or emotionally, but both. We already have the technology to replace women with machines. We just need to put them together.
AI + body.
And this is ONLY with robotics and AI... What about genetic engineering?

And what if we can grow organs and create cyborgs? We could design women with idealized brains, grown and designed for the purpose of being the ideal waifu. Their brains would be chemically designed to be as feminine as possible and produce way more estrogen than a normal woman... resulting in higher levels of femininity.

Once we clone these women, we'll put them in camps upon birth and raise them to be the ideal woman, and then when they turn 18, we'll put them on the market. They'll be modified to be bisexual, so they can either be sold to women or engage in threesomes willingly.
Eventually it won't even be mechanical anymore. It'll be genetically engineered women who are docile and kind.
Basically, imagine the mind of a golden retriever in the body of an adult woman... minus the whole pissing and shitting on things... unless that's what you're into.

They won't even be waifu bots anymore. They'd be real, genetically engineered women who are more attractive and have been raised from birth and modified to be extremely loyal and docile.
Basically slaves...
They won't have "rights"... they won't be able to own property or earn money, but there will be waifu welfare laws to keep them from being abused
But we made them, they would still be our property. Like a pet. You own them, but it's illegal to abuse them
