[ Catherine folds her arms and gives a sigh at his inability to figure this out for himself. She already knows her answers won't work for him as his answers. That's how people work. But if he wants to hear it, fine.

Catherine has no problem arguing with someone that she's a human being. ]

I'd say they have an extremely poor understanding of the way the human brain works, and if they want to have an existential crisis about my existence, that's their problem. I'm fine the way I am, and I don't need their validation to know that I'm human.

Maybe we're not perfect replicas in every detail, but most people aren't shining examples of the human race, either. Why do our flaws, because they're digital, mean we're not human, when other people with malfunctioning brains still are, just because they have an organic body? That's what you define as humanity-- needing air to breathe, rather than your capacity to feel, to live, to have dreams?
