The science fiction AI of my childhood was Cortana, who was a lot more cool than a relentlessly proactive token torcher which burned 12 bucks to fix some CSS.
Sorry, I should've been more specific; like jrflowers said: the Cortana I was referring to was the AI character from the Halo series. I did have a Windows Phone though and thought the Cortana assistant was one of the coolest things back then!
