User blog comment:Ygrain/Revisited: EDI and her purpose in the story/@comment-5287758-20121215162931

What point exactly are you trying to make here? Does this provide a basis for an alternate fan ending? Because what could have happened and what did happen are very different things. All this speculation isn't doing anyone any good you know........

Just kidding. Its an interesting idea. The only problem being EDI is a young "naive" human AI while starbrat is billions of years old super advanced AI created by the "firstborn" apex race. Its very probable starbrat is capable of more than it is letting on. It can(and should) make EDI look like a simple computer program. Also, its not very wise to assume that EDI would willingly sacrifice herself to take the brat's place. EDI probably would be repelled by the very idea of controlling the Reapers as well. Lots of problems involved. I am sure there are lots of logistical problems as well.
