FFS, Mina. Dune is science fiction. Fiction, as in made-up stuff. It doesn’t claim to be a documentary.
The author also forgets that the novel is set in the year 10,191. A helluva lot of innovation can happen by that time.

I second your comment. Furthermore, in many examples, she says it's not possible with present technology. To that I say.... DUH
So many words, so much grunting and groaning for so little reason. The whole genre of science fiction rests on what we have always called
“the willful suspension of disbelief.”
