It's not paradise, it's hell.
The book also addresses this by pointing out that most folks are happy with their overlord, some even worship it.
The point of the book is to prove it is hell.
"It's not paradise, it's hell."
This is an absolutely insane take.
Hell is what happens after they destroy Prime Intellect.
What's hell about the last chapter? (Other than the writing and the author's transparently obvious sexual preferences?)
Death? Hunger? Pain? That's small stuff. It is not Hell.
Hell is loathing your existence forever. The end point of every human is condemned to in that novel.
Let me ask you a question (my answers in parentheses):
Do you fear death (not Death itself, but yes I do)?
What about it (bring unprepared, the pain of the process, fear of cowardice)?
It is fine that the main character hated paradise because she was a selfish moron. But she destroyed paradise for everyone else making her one of the most evil and selfish characters in all of fiction.
