Its a familiar topic of discussion in SF, but one that bears at least an occasional visit. The prescience of Dune: Not just the role prescience plays in the novel, but the prescience of the novel itself.
This essay is short, but I highly recommend it. Do yourself a favor and check it out:

Some excerpts:
It is in reference to our looming fears about artificial intelligence and trepidation at growing inequality where the kind of mercantilism and feudalism depicted in Dune make the novel feel prescient even if accidentally so. There is an Empire in Dune, much as there is a global empire today in the form of the United States, but, just as in our case, it is a very weak empire riddled by divisions between corporate entities that control trade and rival families that compete to take center stage.
Then there is the predominance of religion. Many have been very surprised by la revanche de Dieu in the late 20th and early 21st century- the predominance of religious questions and conflicts at a time when many had predicted God’s death. Dune reminds us of our current time because it is seeping with religion. Religious terms – most tellingly jihad- are used throughout the novel. Characters understand themselves and are understood by others in religious terms. Paul (Muad’Dib), the protagonist of the novel, is understood in messianic terms. He is a figure prophesized to save the desert Fremen people of Arrakis and convert their world to a paradise.

It not just that in Dune we find much of the same, sometimes alien, religious language we’ve heard on the news since the start of the “Long War”, even the effectiveness of the Fremen insurgents of the deserts against crack imperial troops the Sardaukar feels too damned familiar. Though perhaps what Herbert had done was gave us a glimpse of what would be the future of the Middle East by looking at its past including figures such as Lawrence of Arabia off of whom the character of Paul Atreides appears to be based.

The interstellar civilization in Dune is addicted to the spice in the same way we are addicted to our fossil fuels and that addiction has turned the world of Arrakis into a desert- for the worms that produce the spice also make the world dry in the same way the carbon we are emitting is turning much of the North American continent into a desert.
As I was reading Dune the story of California’s historic drought was all over the news- especially the pictures. Our own Arrakis.
