Another example, the universe of Dune had pretty impressive engineering for a universe without computation. Yeah yeah I read the series, don't correct me about the pre Butlerian Jihad era, etc. Dune was mostly a fantasy not sci fi anyway. Note there's hard sci fi and soft sci fi, and a soap opera / action flick which happens to be "in the future" like B5 is not really predictive. I'm just saying that very soft sci fi is indistinguishable from copy and paste style fantasy or historical fiction. Hard sci fi like KSRs Mars Trilogy ages much better than "80s soap opera, on a space ship".
