One thing that always bothered me was the fact that the writers never clarified how robot Moira has actual 'memories'. An A.I. can't truly have memories from before it gets programmed. I guess we don't really know about the process by which Arnab Chakladar (the tech bro from X Deaths of Wolverine) transferred her consciousness into a robot body.
Even if he transferred some form or algorithm of Moira into a robot shell, it should not have actual "memories" of her former lives. It doesn't really have an organic brain. The only thing I can think of is that maybe it works similar to Krakoan resurrection...where a person's entire brain mapping, including certain memories are stored in a crystal? But we never saw that, because...Ben Percy, but I think that could technically explain it.
Moira didn't have a Cerebro backup file stored anywhere, or at least we don't know if she did. During the time she was made "human" by the three dishrags (Emma, Destiny, and Mystique), I guess Cerebro could read and store her mind?
SPOILER FOR ROTPOX #3 & #4!!!
In Kieron Gillen's Rise of the Powers of X, we see that Moira opens a port to the Enigma, who then claims to have access to all her previous lives data...once again, this is impossible unless the Moira bot has a Shiar memory crystal with Moira's original brain imprint as a core. An A.I. begins building "memory" from the moment it is created, but can only build it from extrapolation of information after it's created. Nothing that came before it went online existed.
Was there anything throughout the Krakoan era that explains if Omega Moira is actually the real Moira, or just a faulty A.I.?
