Incels need to form our own sexbot development company. One that explicitly caters to our needs as lonely men only. It should employ only blackpilled men and should probably be a workers coop too so we don't have to answer to shareholders.
Worth a try, but expect ZOG to shut you down if you do something that the gynocracy doesn't approve of.
At any rate, it seems to me that the real technical hurdles for a sexbot are the hardware. I mean, just to pick one problem (out of many) to use as an example, consider body heat. Current sex dolls are cold like a dead body. You might be thinking, "no problem, we'll install a small heater" but not so fast! It's really, really difficult to distribute temperature evenly. A real body is pretty much a marvel of nano-engineering, with microscopic capillaries to move blood around (and that also moves heat around) and even in a real body the extremities often get cold. We absolutely do not have the technology to duplicate the human circulatory system, and if you even tried, you'd be looking at a multi-million dollar sexbot.
Nobody who could afford one would actually need one.
So okay, you say, instead of generating heat and distributing it around the body, we'll just heat it externally. Like, it'll live in a heated closet and when you call for it, it comes out of the closet and the skin feels warm and real. That's a workable idea, you just have to be aware that it's a hack. You have to tell people, "if you want a sexbot, you can either buy the cold, dead, corpse version, or you can buy this extra heated closet thing for extra money, and if you buy that, it'll have a realistic body temp for around 30 minutes or so, then you have to put it back in the closet."
Do you see the point I'm getting at? Temperature seems like such a trivial feature and yet we can't solve it in a realistic way, and the workaround makes the bot very not-lifelike.
Every feature is going to be like that. You want it to move? Have you thought about the sounds it'll make as the motors and such inside it are whirring away? You want it to be self-lubricating like a real woman? Here again you have a problem that requires nano-scale capillaries that we don't have the tech to manufacture. You probably also want it to be self-cleaning, but the self-lubrication hardware will likely be damaged by whatever process you clean it with.
I could go on and on.
To be slightly less blackpilled though, there is one feature that I think they could add that would make a big difference - eye movements and eye tracking. If a doll's eyes would move and try to make eye contact with the user, that would greatly improve the experience. And I think that's doable, with existing tech.
