The story of Dune takes place in the future of human beings, who have already left the earth and extended their activities to the whole universe. However, human beings seem to live in the Middle Ages, but they live on different planets with their families or surnames.

What caused this situation was a Butler jihad, a war between human beings and artificial intelligence.

At that time, the rapid development of AI technology not only possessed human thinking, but also became a necessity of human life. Finally, AI was occupied and enslaved, and then human beings restarted the road of evolution to find their own abilities.

After a long and bitter battle, human beings finally defeated artificial intelligence, but after this battle, human beings made two important decisions:

First, all machines similar to human thinking, including all forms of computer thinking machines and robots, are prohibited.

The second is the key skill point. Compared with science and technology, human beings are more inclined to develop spiritual strength, and then human beings resumed the fief system.
