What fiction books would you recommend for programmers?

Three Body Problem by Cixin Liu, himself a programmer.

Library of Babel, Borges

Terry Pratchett's Going Postal seems particularly apropos these days as we have Reacher Gilts aplenty in the technology news headlines.

Obscure and a bit dated but Bruce Betkhe's Head Crash is hilarious if you've been deeply immersed in the software industry.

Cryptonomicon and Snow Crash, Neal Stephenson

The Vorkosigan Series, by Louise McMasters Bujold. She’s won six (!!!) Hugo awards for her writing, and as Anne McCaffery says, “Boy, can she write”.

Space opera with warfare, intrigue, politics, drama, and world building.

These are all entertaining:

Definitely the Wizardry series by Rick Cook

The internet and AI long before the internet and AI.

David Gerrold - When H.A.R.L.I.E. was One - and other tales involving Artificial Super Intelligence

William Gibson - Neuromancer and related - Cyberpunk series, the Difference Engine - a Steampunk technology tale.

'Stories of your Life and Others' and 'Exhalation' - by Ted Chiang. In his short stories, he introduces advanced concepts from mathematics, philosophy, and computer science in a way that’s subtly woven into captivating narratives.

"Frankenstein; or, the Modern Prometheus" by Mary Shelley. The themes in this book are more relevant now than at any time since publication in 1818, and to nobody more than ML coders.

Eon by Greg Bear.

A Deepness in the Sky by Vernor Vinge.

Laundry Files Series by Charles Stross Written by a ex-programmer, features a world where magic is a branch of mathematics, so you can for example write an app to summon demons, or accidentally turn yourself into a vampire by implementing a particularly extravagant algorithm.
