Cortana 'used' to be a human.
Kind of...
Smart AI's are created after the brain pattern of humans, and usually, those are either already dead, or die after such operation.
I don't clearly remember why or how, but Dr. Halsey, or however you spell it, survived the operation... I'm probably mistaking, but I think they had 'cloned' her brain of something like that... I'd be able to tell you more if I had the first novel with me, but I'm at school at the moment.
This is all explained int he first one, if you want to check it out.
