They already discussed that he isn't an AI. He's a real little boy. They used a real little boy and turned him into this
Oh for what I understand, they used the boy's body...but i think the brain is no longer of the boy's..hence it became a robot for sex purpose
The author has made it clear its still his brain and that he's a human. He is still human with a functioning, albeit reduced functioning, brain. He was either killed or suffered severe head trauma and they brought the body back to life, meaning all systems are go again-- the brain being part of that. So far it seems they took a corpse and reanimated it. If its alive again, its a little boy again. The only differences are that they genetically modified him (his spit and sex organs) and added a robotic prosthetic.
So the baby can have wet dreams too? Then they are not AI it's a fully functioning preteen lol
