A work of Speculative Fiction by Charles Stross. Can be read here.
This series provides examples of:
- A.I. Is a Crapshoot: in several manners of speaking.
- Apocalypse How: A variation on Stellar, in the sense that the solar system isn't destroyed per se, just converted from dumb mass to computronium by the Vile Offspring. The (trans)humans who weren't active (or involuntary) participants got the hell out while the getting was good.
- Augmented Reality: Pretty much everybody.
- Cats Are Snarkers / Cats Are Superior: Aineko lives for this.
- Deus Est Machina: Aineko, by the end of the book — and arguably a good bit earlier.
- Brain Uploading: A large part of Accelerando is from the viewpoint of characters who uploaded themselves as a way of saving space on an interstellar journey
- Fantastic Religious Weirdness
- Accelerando does strange things with the intersection between shari'a and corporate law.
- To say nothing of the difficulties inherent in facing Mecca to pray while you're in space.
- Generational Saga: Accelerando has three generations of protagonists.
- Invisible Aliens: In Accelerando, they built Matrioshka brains and subsequently vanished.
- Multiple-Choice Past: Sirhan has a real one, courtesy of his mother. That is to say, his personality is a merge of at least four different childhoods, grown in parallel.
- Non-Human Sidekick: Manfred's cat who is a combination of a Talking Animal and Robot Buddy and, it turns out, is behind almost everything
- Oh, Crap: When the protagonists realize why the Vile Offspring are resimulating individuals from human history.
- Patchwork Story: Accelerando started its life as nine short stories.
- The Singularity: The entire point of Accelerando. Glasshouse on the other hand stars the people who survived it and decided it had been a really bad idea for the most part.
- Space Elevator: Used by the Matrioshka brain in Accelerando to disassemble the inner solar system.
- Starfish Aliens: The extraterrestrial entities encountered by the passengers of the Field Circus are almost incomprehensibly different from humanity - one of them isn't even a "real" alien at all, but instead a corporate scam disguised as a digital upload of a naturally evolved organism. The only reason that Amber and Co. are able to communicate with them is because of the hyper-sophisticated translation software they have at their disposal - and even that sometimes fails to get the job done.
- Although not "aliens" per se, the Vile Offspring can also be said to qualify for this trope.
- Transhuman Treachery: The Vile Offspring became so technologically and neurologically divergent to humanity that the humans had to flee the solar system to avoid being being used as Matrioshka Brain feedstock — along with the planets of said system.
