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.
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.
