> An essential fact of the Dune universe — but one that goes unmentioned in the movie — is that there are no computers. Around 10,000 years before the events of Dune, a mass galactic revolt — the Butlerian Jihad — against “thinking machines” ended in a new commandment, adopted by the universe’s many religious sects: “Man may not be replaced.”

That part is very interesting, I wonder why it wasn't ever mentioned. It explains SO MANY things.
