In japan it is already happening with the virtual idol. As a introverted guy who doesn't get laid nearly as much as he likes to I will put this forth as guidance on my mind set and how similar ones may do the same. I will go for the average girl but going for the lower then average girl doesn't work for me because beauty is calculated into the equation always. This is beuaty independent of age and signs of it.
personally I will always strive for the real women over the personal automaton any day even if it's a little harder for me to find a date but I cannot speak for the next generation of introverts sadly and so you maybe right. This also brings up a sub market of mechanical Turks. Women (or men for that matter) who control droned robots to give them realistic responses while somone else (the client) interacts with them.
I can see it getting worse and worse and I'm not going to lie it is hard to get out there and meet attractive women. In some places in the United States I could easily go around and not really feel like there were hardly any attractive women living in that area. This could drive guys to just give up and also drive women to give up.
