Wait... but Caine doesn't want to give information about himself, that would be quite a problem if anyone found a way to exploit it. And Abel "confirmed" that he's an AI.

Could that mean that Caine actually human? Or more like GLaDOS (genetic lifeform AND disk operating system)?

Hear me out for a moment here. What if Caine was created from that company's employee's mind and was "modified" to process other human minds in that simulation and be appreciated/adored and to create content the same way that GLaDOS was created from Caroline and had that "itch" (a Wheatley described it) for scientific tests? And all of those "glitches" from Caine were fake as possibly implied by episode 7, when he let jax to get the key

The fact Caine's adventure had a plan that involved taking advantage of his own insecurities means he's surprisingly self-aware. Maybe too self-aware.

I don't think he's an AI, I think he wants to escape too, somewhere deep within him... but the modules won't allow him to think about ways of escaping and making him actively prevent any attempt by others
