A very interesting long article at Tyler Durden's Zero Hedge website, authored by Madge Waggy. It looks at how far androids have come since the early days of vaguely humanoid robots.
I have not read widely in the relevant literature, but I've had a notion that I've not seen elsewhere. It is that the real market for artificial women exists in China where the results of the one-child policy have created a decided scarcity of young women.
In a true market economy, that need would produce product innovation; China is not entirely a market-driven economy. China's government exhibits outbursts of prudishness which militate against this innovation.
In the US the market demand will be for live-in caregivers for the widowed or single elderly. A talented artificial companion would enable individuals to live at home for years longer. Why shouldn't these resemble an attractive young adult, with designed gender of your choice?
