While I've found an
AI inhabiting the Citadel in Mass Effect 1, and it's arguments are basically the same as Starchild's in Mass Effect 3, and it's motivations aren't really different (reach out to the geth and try to investigate the rumors of a
giant spaceship far more advanced than any other at the time), there's still a good chance it isn't EXACTLY connected to the ending in Mass Effect 3. Or maybe we all skipped the assignment to neutralize it in our playthroughs and that goddamned AI is the Starchild. Bazinga. Or not.
Yes, I am being silly. Or at least trying to.
What they dislike about the starchild is that, while we could ask Vigil for information on most stuff there, we can't get good/reasonable explanations from the child, specially in the hows or whys of the problem.
