Yeah in the books the universe life is kinda shitty for tens of thounsands of years because of the restrictions on "thinking machines". It is pretty much a blanket ban on much above a 80s level non networked pc. Anything that breaks it is pretty much black market good or used an excuse for military take over by a stronger feudal house. All automation pretty much requires a human in the loop. Also any machine a "in a image of a man is banned" also pretty much a prosthetics will get the owner killed. The Dune universe is a dystopic hell hole for anyone not a member a noble house or an administer for Chom mega-corp.
