"Sex and marriage with robots?"

After reading this article, I am very worried about our future. I can see human beings using robots as potential sex toys, but I think that having a significant relationship between a robot and a human is stepping over the line.

The article suggests humans are able to develop feelings towards computers through the example of students becoming attracted to Eliza. And, obviously, if robots are programmed and designed for humans to have the ability to interact with them, then there will be a strong potential for attraction. But a human must understand the key word "PROGRAMMED." A robot is programmed to share the same interests but does not have emotions and, therefore, cannot fall in love with it's apparent significant other. How are you supposed to marry someone to something that doesn't understand the concept of marriage on an emotional level? The robot may look and talk like it's in "love" with the human but it wouldn't have any emotional attachment to it's "significant other."

And what about reproduction?
