E: sorry slight spoilers for old and popular science fiction series. (You'd think they would have picked some more positive but less well known transhumanist science fiction books with nice societies, or pick specifics they liked but nope).
The Foundation is a horrible place to live, it is a frontier city created under false pretenses where you live under constant threat of a crisis, manipulated from afar by the second foundation, while 'Rome' falls apart around them. Billions die.
Hyperion is a horrible place to live, the main hegemonic force is a hypercolonialist empire that destroys all variety, kills the dolphins, is secretly run by AIs who abuse humanity, power everything by destroying the energy that gives us love, and morph into a authoritarian theocracy secretly run by AIs who are now at war with the beings in the love dimension. Also, billions die when the first empire falls.
Ringworld is ... not a book series I remember much from, read it when I was young, might be ok might not be.
Also all these worlds also have a big magical element in it, dune with all the spice stuff, hyperion with the love dimension, foundation with the psi powers and magical prediction powers. And they are setups for the stories conflicts (and well, stories).
It is all a bit like saying you want Singularity skies Festival arrive without reading up on what happens afterwards. Helps if you actually read books not skim through them in 2 hours.
E: I need to make a confession, this guy changed my mind on agentic LLMs. They should use them, it will improve their reading comprehension. (they should also add pronouns, if they don't want to be called they)
