So either they were lying for job security, or Frank Herbert is one of those idiots who thinks that the human brain is a spectacularly powerful computational device whose capabilities have just "not been fully tapped". The Mentats would be intelligent if they were using computers secretly, while pretending to hate them. As it is, they're just part of a grand society of religious fanatic Luddites.Scorpius wrote:1. Mentats CLAIM their computational power far exceeds that of the computers of the past. They don't believe that they have a use for these "trifling machines." It could just be a form of job security but the novels state this opinion many times.
OK, let me clarify: the whole society of Dune is composed of morons, not just the Mentats.2. Anyone who attempts to subvert the Butlerian Jihad and the Great Convention would face the combined might of the Emporer and Great Houses (Leto II dared to use technology because his power was absolute.) That means that anyone (Mentats included) that used AI technology would be put to death instantly. Even if someone thought it was a good idea, they couldn't use it for fear of society's paranoia about AI's. That's why IX and the Bene Tleilax were considered outcasts: they were SUSPECTED of making machines that violated the rules; it just wasn't proven yet.
All of which would be far more efficient with the use of computers. Do you know how many computers are built into a typical modern automobile? Do you know how much of the fuel-efficiency and performance of that automobile is a direct result of these computers? And besides, who said they don't have tech? They just don't have computers, which severely limits the performance of their tech.3. To the commentary that they don't have tech: massive city-sized buildings, giant spice harvesting machinery, galactic trade, Lasguns, galactic spaceflight of massive quantities of people and materials anyone? Hello?
There are simpler ways of overcoming personal and emplacement shields. That was my point.4. Personal shields and emplacement shields have supposedly made many weapons obsolete. The Harkonnens won the first Dune battle because they found ways to nullify this advantage on Arrakis, both at the personal and emplacement level.
It's "playing dirty" to use artillery or napalm, but not playing dirty to launch sneak attacks?5. The government is fuedal in nature with wars being fought in specified ways: ie. War of Assassins, Kanly etc. They may be fighting the wars in these ways due to "codes of conduct" because of the fear of what everyone might do if they "played dirty." The winners would always have to worry about how the method of their victory was perceived politically by the rest of the Empire. They could win the battle, but lose an allies' support.
I said nothing about using nukes. You could easily overwhelm personal and emplacement shields through other means, such as napalm, heavy explosives, high-momentum impactors, etc.5. How big would the stakes have to be in order to violate the code of conduct and break out "really dirty" weapons? Muad'dib, who's playing for an Empire goes to great trouble to explain that he didn't violate the Great Convention by use of Atomics. He's still playing by the rules even though he brought the Empire to its knees...
The book is enjoyable if you can get over the sheer stupidity of the backstory. That a society should advance in any meaningful way while under the grip of such religious fanatical idiocy is one of its most bizarre implicit claims, particularly when this particular form of idiocy is overtly anti-technological.Stupid? Sure. But in the end I think Herbert was trying to show what happens when dogma and religion are intertwined with politics. He also wanted a Galactic Empire that still had a use for the romance/adventure a good swordfight provides. Maybe somebody should've handed him a lightsabre...
