Disagree for dungeon crawler carl & any of the Bobiverse - while they're fine books, wouldn't class it in the category of interesting ideas, it's just pop fiction.

I'd look at the following:

Hyperion Book One (For the book style + ideas throughout the short stories - you only need to read book one)

Solaris, Lem (What would an alien intelligence truly look like, especially in planet size scales, really interesting theories)

House Of Leaves (Classic for exploration of horror - not sci-fi, but within the wheelhouse)

Maxwell's Demon (Hated the ending, but the first half of the book explores some interesting ideas)

Children of Time (Good sci-fi based book exploring morality + intelligence)

Annihilation (Sci-fi, no spoilers but great book)

Venemous Lumpsucker (near future sci-fi, fantastic as a set of vignettes within the story)

Closest to Antimemetics divison personally would be Maxwell's Demon + House of Leaves.

My hard disagree on the Bobiverse as well. Feels like the typical book I ought to like based on my interests and the other things I like, but the ideas somehow fall way, way short of qntm's writing.

And +1 on "Annihilation" – I started reading that to another recommendation for "books similar to TINAD" here and basically couldn't put it down. The similarity is purely based on mood, though – don't expect an actually similar novel in terms of ideas and presentation.
