Basically markov chains trained on Gibsons books. Programming something like that is starting to feel like the "hello world" of information theory.

Looks like somebody even made a cyberpunk style markov generator:

I think the next step up from a markov chain is throwing the results into https://github.com/languagetool-org/languagetool and checking for grammatical correctness, and retrying each sentence until valid.
