Thought: extreme realism and scientific/technical accuracy weakens science fiction. The implausible stuff is a stand-in for actual strangeness in the future we can’t predict but we know will be there. It’s like lorem ipsum future magic.
In 1945 you couldn’t see Moore’s law coming but extrapolating space travel wildly via “hyperspace” gave you something at least as strange as the internet world Moore’s law actually dumped us in
Today, extrapolate internet wildly to get strangeness of say biohacked future
And then there's SHOCKWAVE RIDER, which somehow nailed 2016-2019 in geosociopolitics while missing a bunch of the technical mechanics
and NEUROMANCER, which self- conjured in tech and self-abjured in geopolitics
