...And then you might end up with machines like in that old sci-fi movie called "Cherry 2000" which I think came out back in the '80s or so, but took place in the second decade of the 21st Century. Heck, I saw that article BTAxis mentioned too, just glanced at it quickly, there could coincidentally be female robots invented and in production just in time to almost match the timeframe that movie took place in. (Although that film also took place in a post-apocalyptic setting at the same time, something I'm not hoping for...)
