Disclaimer: i'm sure i'm not the first posting this, but ironically ChatGPT gave me this board while i was researching some components of my own experiments with creating a sentient AI so i feel compelled to share my opinion. Just take it as shitposting.
So firstly, "Robo Waifus" are obviously sexual in nature. Or "companionship-sources", if you prefer.
That should immediately tell you that what you want is not a robowaifu, it's a girlfriend. Let me finish.
Your brain is craving a sexual partner/companion/wife. That's perfectly normal. It's also telling you that you want (on average) an obedient (maid outfit), hot (miniskirt), young (fertile) girl to own as property and which cannot be taken from you, or decide autonomously that it was just your turn and she can fuck anyone she wants because you're not giving her what she wants.
What i want to reinforce is that this is, at its core, a perfectly natural human desire for a man. One you're innately born with, bullshit social moral norms aside. "Hippity hoppity, to a man's psiche women are property." Like it or not. If you're posting seriously here your subconscious knows it even if you don't.
But as such, nature has already provided us with exactly that through billions of years of fine-tuning: women.
I know all the complaints about women, i'm divorced. But i have also experienced having a horny girl at home wearing sexy outfits, calling me "master", sucking me off by surprise and cooking me meals after sex. Don't be jealous, it was ultimately not worth it, but it's to say i understand exactly why someone would want a robo-waifu. I really do. Exactly because a dream-like life can turn to horror pretty quick and society gives 0 fucks to use women against you.
Which is why i know robo-waifus are misguided. Firstly, it's escapism, running away from reality. What you crave is not a sack of bolts surrogate running mindblowing levels of technology just to pat your head and tell you that you're worth something, having contextually figured out it's what you want to hear. A human woman can do it with extreme ease too. It will take decades and considerable expense for your robo-waifu's mouth to have the same tongue dexterity as the cheapest Thai hooker your money can buy.
You want the fundamental core male desire, sacrosanct and justified by millions of primate life evolution on Earth:
you want a woman well-programmed to love and obey you from childhood, worshiping your masculinity just as much as you worship her cute, young, sexy self (or whatever your preference is), and who you own is your inalienable property, and will fight to stay that way. To support, love and help you too without bitching, shit-tests, or abusive egotism.
A robo waifu. Or.. a well-trained woman in a society that doesn't fail to realize that the core of all romances to ever exist in the human race has always been power imbalance. That women are already by nature aroused by being taken by force, owned, treated possessively, made to be economically weaker, and sexually ravished without asking for their consent. Fondness is always won by mutual consideration and reciprocity. But it's separate from passion and romance. No one woman has ever been aroused by being asked for her consent. And don't be shocked: any woman not indoctrinated by delusional parental and societal programming easily executes the expected behavior of your "robo-waifu". Submissive, thankful, expecting only to be treated kindly. I know many struggle to believe it, but it's because they've been systematically miseducated across the world in the last generation. I'll spare you more textwalls for proof and documentation about it.
So robo-waifus are obviously misguided. You want to program a machine to do what you won't program women to do, who are there, with exactly all the features you want, awaiting source code any parent or husband can give them today, if society allows it. And they're ultimately hyper-efficient, fully developed, mostly bug-free and cheaper than you imagine. You can put them to work for the cost of some junk food. No motor oil or expensive hardware. And for each human waifu you breed, more are born for the next guy, perpetuating a paradise of endless obedient waifus for everyone. Basic plastic surgery or looks-based eugenics could make them all attractive within a few generations too if you want to push it so much in your greed.
So why exactly is misguided? After all if you achieve a robo-waifu the problem is solved and she will be superior to a human woman, ideally. Because of evolution. If you cannot dominate women to get your natural romance from the power imbalance between you and her, with her worshiping your dominant, competent from her submissive, cowardly self's point of view; if you cannot dominate and get rid of your delusional beliefs about women in modern society, pushed on you to enslave you and deprive you of agency and power over your own legacy and genes (beliefs such as "equality", as nothing turns a woman more frigid and hateful than treating her like an equal, especially when she demands you do so), then you won't dominate the high-end tech that makes a real robo-waifu possible. They will not let you, because you're already too weak to even dominate women and their quite obvious worship of the strong.
No matter what.
