If you're talking about Sentience, I wouldn't rely too heavily on that theory. Sure, the official word is that he was promoted due to fulfilling his goals and yes, he was certainly more human in behavior than any of the others we've been in contact with so far but the timing is suspicious at best.
Think about it. Sentience imprisoned the Engineers because he believed they were guilty of a crime. They in turn oust him from power and put Acumen in his place. Then Sentience led the coup that changed the power over again, followed by his "promotion" that ultimately lead to us being transferred to a new prisons with an even higher security level in regards to the AI.
