Artist Matt McMullen was trying to make art when he created his first lifelike miniature doll. He posted pictures of the little lady on the Internet, and surprisingly, somebody asked if it was, you know, doable. McMullen got an idea, and the RealDoll was born -- an incredibly realistic-looking sex doll complete with orifices, real-to-the-touch skin and hair, and, more recently, moving parts and programmable personalities in some models.
So what's the problem?
Other than the fact that you can now get rich selling life-sized masturbation aids (and they cost up to $10,000,) you have to ask what's the purpose of a RealDoll beyond what could be accomplished with the much simpler and cheaper Fleshlight (Google it -- or you can just figure out what it is by the name). Does making her look like this ...
... create a more human connection? Because she ... what? Fools you into thinking she's a real girl?
