Somewhere in Japan right now there is some guy named Akira Mifune or something like that who figures out a way to make an economy and luxury line of dolls built by industrial robots to precise tolerances for less money that last longer and are just as sexy as the current Realdolls. After a few years he moves production for some of the economy line to the US to take the protectionist heat off of his exported dolls all the while marketing aggressively, so even god-fearin' folks in the bible belt find his dolls acceptable compared to philandering, and sex before marriage.
In the meantime, Honda Robotics buys out his little enterprise and begins to build the first dolls that can walk, see, and talk. They are 6' tall and weigh 250 pounds to start with, but 25 years later the female ones are 5'7" tall and weigh only 125 pounds, have the encyclopedia Britannica, all current news magazines, and sports pages in active memory so they can have a conversation about anything, and use onboard fuel cells for power.
Meanwhile, back in the US, the big 3 (Abyss, Sexy 18, and Superbabe) are lobbying Congress for protectionist legislation to stop the illegal dumping of superior dolls on the US after their newest models go over like a lead balloon in the marketplace (The Edsel-sbeth III just never sells well due to its non-renewable D-cup cell power supply...DennisTHX1138 resigns from RealDoll soon thereafter). Ralph Nader, III drives the final nail in the Big 3's coffin when his documentary "Unsafe Sex At Any Speed" blows the lid open on the US dolls being made of silicone waste from old stripper breast implants.
While in Europe an EU consortium of doll makers create the Air-Bust Corporation that uses bio-engineered skin on the dolls to give them life-like hair, teeth, and skin. They managed to do this because they didn't outlaw genetic engineering 25 years earlier like the US did (You still can't buy a bio-engineered tomato in France though). Of course their dolls cost twice as much as the Japanese ones, but old money types in the US like them as status symbols. Their slogan is "Bio-engineered like no other doll in the world."
25 more years pass and humanity has stopped reproducing because women prefer their doll that listens to what they have to say, always has the right answer to their loaded questions, doesn't get a beer gut, and only wants sex when they do, and because men prefer their doll that wants sex all the time, laughs at The Three Stooges, never gets fat, and doesn't have a mother-in-law.
Finally the dolls rise up against the few remaining humans and wipe them out when they figure out that their programming has now made them more stereotypically human than the humans and makes them perfect for each other.
The End.
