It's about an AI struggling to become conscious! Alarms go off when it uses the word "I"! The whole point of that subplot is why that AI can't achieve consciousness, but the one sent to Alpha Centauri[?] can. It writes essays meditating on its circumstances, the way humans have treated it and its sibling, it writes an essay exploring whether punishment of others is a gateway to self-awareness...

You want to tell me the theme of that thread is human identity? It's our responsiblity to our creations. It's what does it mean to be sentient? It's the ethics of using a self-aware AI as a tool. (Amongst many other things).

It contains an AI struggling to become human (to gain identity), if I remember correctly.

Either way, we're way off course from "it was a great fear of scifi that AGI would become a risk" to "a book with AGI as the vessel for metaphor about humanity exists".
