I think it's kind of ironic that half the time people on internet forums "get" the idea that there is more to a relationship than sex, and other times they seem to miss out on that point entirely.
As someone who grew up with stories by guys like Issac Asimov with people falling in love with robots or computer programs (in other fiction) the idea doesn't inherantly surprise me, assuming such programs are capable of providing a degree of companionship and company for the people involved.
Now, someone might wonder how a program like that can provide satisfying company. Having never "fallen" for a program I can honestly say I don't know, however I guess it doesn't surprise me given that we're arguably coming close to true AI or VI systems. Chess Masters have lost to computers finally, and I could have sworn I read some stuff a couple years ago in a similar vein to people producing programs that were capable of passing the "Touring Test".
The Touring Test is to put a person into a room with a computer and tell him he'll be communicating with another person via keyboard and monitor. The test is to see if the illusion can be maintained that the person is communicating with another person despite only talking to a program.
Years ago "virtual personality" programs were popular where you could have a conversation with a program called "Freud" or whatever, though most were not all that convincing. It was mostly fun to see if you could get the program to talk about itself (which it could not for all intents and purposes). Such programs came the closest to passing the test which is why they were "nerd chic" for a time. However assuming someone *HAS* created newer and more powerful versions that are capable of passing as people under a total blinder, intellectually I can see how someone could get a sense of companionship from such programs even if I don't feel it myself.
The idea doesn't specifically bother me to be honest, and I figure at some point we're going to get to the level where this becomes more than a fringe issue. Largely because speculative fiction writers saw this coming long ago.
As far as girls feeling inferior to the programs, I have to question that bit. I didn't hear how the questions were asked to know how accurate the response is. I would suppose that the real issue is that most girls simply can't be perfect all the time. Also such programs become an extension of the user, something that can be turned off or shut down at will. A real person can't compete with something like that, especially seeing as they have their own needs and desires.
In the end I can sort of see the "problem". If a computer can provide the companionship people want (though I imagine they will have to become much more powerful than they are now), the only benefit to real people of course becomes sex, and of course this comes down to body image and self confidence issues to begin with. People who realize they aren't attractive are of course going to rely on their personalities for close/romantic relationships and companionships, and if they can't compete with a computer that provides just as much in the end... well I see the issue.
Just file this away in your minds, we'll see where it goes down the road.
As a side note, humanity is already overpopulated. Anything that lowers the birth rate is arguably a good thing. Should someone come up with viable ways for dudes to get sexual satisfaction without women, that combined with the evolution of this technology will probably have a noteworthy effect on the population.
We are however a ways away from neural stimulation technology, or the affordable production of sex androids/robots.
