However, the brain is destroyed during the process, so all AIs have to be made from either flash-cloned brains (Cortana) or the brains of the recently deceased (Sif). It's why Cortana - modeled off a flash-clone of young Dr.Halsey - is essentially young Dr.Halsey.

So, technically, everyone's right ^^
