At first I read this as "are you human enough" which got me thinking, maybe this was an analysis on metastability and what it means to be human, as well as questioning Wash's humanity due to Epsilon being implanted in his mind and then immediately trying to kill both of them. Or maybe it could just be about AI implantation in general, how you quite literally share your brainspace and neurons with an artificial being, via artificial connections fusing metal and flesh. What if having an AI does take away your humanity, even just a little bit? How does it change you, mold you, cause you to do things you never would've before? The only reason Maine became the Meta instead of North, Wyoming, or hell, even Tex is because Sigma was the only fragment who sought out metastability. If Theta had sought it out, could he have turned North into the Meta, stripping away his humanity in the process? And, what does it even mean to be human? In his first appearance, Church (as Alpha) had a human body, and saw himself as a human. Granted, the body was not his own, but the point still stands. Was the Meta human when it had all its AI? What about after the EMP destroyed them, was it still human? It had a human body, but not necessarily a human mind. What about Alpha when he was in a robot body, and viewed himself as a human ghost? We know he was an AI, but he didn't. He just thought he was a human. He almost certainly had not reached metastability, but because he was not aware he was an AI, he didn't have any baseline except for being human. And hell, on the metastability thread, it's arguable that Epsilon reached that stage, and that him killing himself inside of Wash's mind was the rest of the rampancy process. Could Sigma have achieved metastability the same way? Being human is an incredibly complex thing, much moreso than being an AI. Because Church is an AI, but any fan of the show would argue that he is human, either iteration of him. Is a human a naturally-formed mind inside of a body of Homo sapiens?
