"Thou shalt not make a machine in the likeness of a human mind"
-Rayna Butler,as told to her by the spirit of Saint Serena
If I only got to take one Sci-Fi book with me to a desert island, Dune would be the book!
Frank Herbert understood people and he had a better than average understanding of what makes us Earthers tick.
Critics like to praise authors as "prophetic and visionary" I'll accept "visionary" for this one. Herbert created a very plausible far future.
