These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Horror: Nobody knows how long Sam's species lives, because nobody's ever lived long enough to die a natural death. Sam is already considered old by his species' standards, so he could die at any moment.
Genius Bonus: When Winston is talking about "dots," little mini-ecosystems with dead land between them, some of which die, and others of which will eventually cover the whole planet, common patterns from Conway's Game of Life are shown in the background. See here for details.
From an A.I.'s perspective, the Gardener in the Dark "upgrade".
From the perspective of any human in the setting who takes the time to contemplate how necessary functional A.I.s are to the comfort level of their society, the Gardener in the Dark "upgrade".
When Doctor Bowman realized his species (uplifted chimpanzee) was too aggressive to survive, he neutered himself. With a sharpened plastic spoon.
It's pretty unsettling how people like the Mayor and Varroa write Florence - an obviously sapient, active, emotionally engaged being - as nothing more than an AI, especially when they hijack her with direct orders and her remote.
Varroa: Don't be silly, AIs aren't people ... If they were people, we couldn't sell them.
Strawman Has a Point: Sam Starfall is, by Word of God, meant to be a comedic exaggeration of human laziness and kleptomania in support thereof(as in, his entire species considers theft and deceit virtues). Funny thing? He's never done anything any human in history has not. This means when someone actually asks him to unravel Kornada's plot, he cracks it in minutes. Though in the process he smashes the worldview of some verynice robots to pieces. And ultimately, it seems he's the one to finallyput the kibosh on the whole, "lobotomize all robots" thing... by pointing out that if humans don't act to preserve robot rights, they won't be the ones to profit from them - it will all go to the rich people instead.
Values Dissonance: According to Sam (and Word of God backs him up), his race evolved as scavengers so stealing and deception is in his genes. It's considered among his people a survival trait to be able to deny resources to competing tribes.
