I am re-reading Dune. This quote by the Reverend Mother Gaius Helen Mohiam is remarkable:

“Once, men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them.”

It's not about a Terminator-style AI-apocalypse where the machines want to kill us all dead. It's just an accurate prediction of what actually appears to be happening.
