As an example, I love the Martian, and I think a lot of older books from authors like Asimov are heavily into engineering / competence porn. Other favs in this category include the standalone novel Rendezvous with Rama to leave you wishing for more, most of the Culture series for happy utopian vibes, Schlock Mercenary for humor, Dahak series for fun mindless popcorn.
Edit: I’m so happy to have found a replacement for r/books and the rest of them.
I’m on the third book now. It’s great nerd/competence porn. I set the 10 minute timer and put my ear buds in at night as I go to bed. I’ve usually drifted off by minute 9, but not because it’s boring or anything, it’s just good listening.
