I guess it comes down to that thread that was on hear the other day - can robots ever be human?
I guess if it was artificial intelligence, Battlestar Galactica style, then there would be no difference,
but with the current technologies whose to say we don't already have relationships with our computers (though not traditional as we would have with a potential paramour)
I mean, a relationship could possily be defined as thus: "A trading of services and needs until one comes to depend on each other"
Think about how depended we are on machines for emotional content, such as laughing at the latest Yatzhee vid, scorning republicans on newspaper websites, even though I don't there are a substaintial amount of people who depend on the internet for the weird affection provided through pornography.
I know I love my little computer, it always works super fast, got some great apps, never lets me down. If my computer was a person - well it would be something akin to a slave as all it does it what it tells me.
I don't know where I'm going with this, I just like the sound my keyboard makes when I type...
