I think the best one of those I encountered was an SF story where the navigation for FTL was done with slide rules.

But demanding that fiction predict the future is unreasonable and will cause upset for you and the authors. Almost all speculative fiction is based on "what if": imagine if there was something different about the world or or our technological capabilities, what stories could we tell about them?

(That's not even counting the SFF that makes no claim to be about the future or reality, but simply brings in elements for dramatic effect. That's why you can hear things in film space battles, which tend to be organised like WW2 carrier/air battles. That's why Harry Potter books make no attempt at consistency.)

As in, you're impressed that someone writing in the 1950s predicted information warfare?

I can see what you're thinking, BSG passim, but no. They just hadn't predicted the miniature electronic computer.
