>If a robot were as intelligent as a human or smarter, would you be friends with it?

If it's sufficiently smarter, I think you'd really have to be more worried about why it would want to be friends with you than worried about whether you would want to be friends with it. Less Commander Data from Star Trek, and more "Her".

They'll probably be vaguely disgusted that we're responsible for their existence. Imagine if you met God, and he was a gross, slow, disappointment.
