    It has been a while, but I’m pretty sure the bladed weapons are needed because the shields specifically block objects with high kinetic energy. I also recall one of the houses on arakis getting bombed, but only after they were able to turn off the protective barrier. I might be mixing up Sci fi books, though.

      You’re not - it’s pretty explicitly the point. The technological arms race has gotten so advanced that everyone has devolved into fighting with knives.

        And even then, the training focuses on slow, deliberate moves, as even a fast knife can be deflected.

        The shields don’t just protect against kinetic weapons, they also tend to cause energy weapons to blow up in a thermonuclear explosions iirc

          Specifically it causes the explosion at both ends, so firing a laser at something you aren’t 100% absolutely positively sure is unshielded is suicidal.

          Sounds like a drone dropping an energy weapon on a shield users head would do the trick then.

            iirc computing is pretty gimped in Dune as well because of previous issues with AI, humanity limited development on that front and focused on developing human capabilities instead, which is where spice came into play…it like super charged your cognition in order to navigating ships through space or something like that. Someone familiar with books please correct that I’m sure it’s not perfect.

              That’s right. There was a war called the Butlerian Jihad in which humanity wiped out anything close to AI. Since then it has been high-treason-level illegal to “make a machine in the image of the human mind”.

              That’s why they have “Mentats”.

              Also, the book was written in the 1960’s. At the time, you still communicated with a computer using a teletype because nobody had thought to put words on a screen yet. You can also see this in the original Star Trek - they never show a screen with text on it.

            There are cultural implications. For the same reason that thermonuclear warheads are stockpiled but not used these days, they avoid using lazguns because you simultaneously blow up more than you would need and turn everyone against you. There are laws in the empire that prevent a military power from intentionally triggering one of these reactions for obvious reasons.

            Usually whenever I ask myself “is it X or Dune?” I default to Dune, since it is just that old and has inspired so many things in sci fi.

      You are correct. But the movies did indeed make a poor introduction to the shield technology. I think it was just a short mention when Gurney is training Paul and is easily missed. They even have to train for a specific fencing style that involves slow movements as a fast swung blade can still be stopped by the shield. And I don’t remember them talking about the interaction between lasers and shields at all, which creates a huge explosion.

      My bigger issue with the movies was the typical hollywood charge. No tactics or strategy involved at all. Just screaming and running.

        The shield-based fighting style was also a small note that was missed in the duel between Paul and Jamis in the movie. Paul was missing what they thought were clear cuts and as a result they believed he was cruelly toying with Jamis, but it was because he was slowing his blade at the very last moment due to shield training.

        Also a slightly weird moment for me as a book fan was when the thopter Duncan escaped in clearly showed that it had shields with a rock crashing off of it, but then he was being chased by lasguns immediately after.

          Glad to know I wasn’t the only one who thought that was a bit off-putting. Same where the Sardaukar try to use a laser to get to Paul, nobility is almost guaranteed to wear a personal shield, so that felt like a very bad idea. Although you could argue that Sardaukar are fanatic enough to not care about getting wiped from existence in a nuclear explosion.

          From what I remember the movie ignores the lasgun and shield interaction completely, which I think is a reasonable tweak to keep things simple and allow them the to use the nice aesthetics of lasers.

        My biggest gripe with the movie currently is that when a Crysknife is drawn it must draw blood before being sheathed again. If you don’t use it on someone you must cut yourself. This is explained to the reader in the book, but in the movie it includes the scene where it would be explained but isn’t mentioned. It’s not a huge deal. They can just ignore it. However, at the end of the movie the Fremen have their knives drawn and it focuses on them cutting their hands to sheath them. I’m sure people who didn’t read the books before seeing the movie would think it’s really weird, especially for a culture so obsessed with water (although I don’t recall if they’ve discussed recovering water from blood yet).

      Yes it is because of shields. Laser fire on shields makes a nuclear explosion and I think most fast projectiles are reflected.

We could be onto something here… Let’s add an overarching father figure that turns out to be the bad guy in the end and some bullshit “ancient riddles” that a 10 year old could solve and are pointless to begin with and Bada bing bada boom, we’ve just written the next Dan Brown novel!

    The movie had its problems and I’ve never read the books but even I know the answer is because the shields don’t stop slow moving objects otherwise you wouldn’t be able to pick up a cup. It’s even explained in the film, admittedly very briefly.

    But then again that’s also how personal shields work in Stargate

      Also a laser hitting a shield causes a massive explosion, which could be at the shield or laser gun. Bullets get stopped and a laser would likely kill either user if many kilometers away, or both of closer.

          I’ve read a few of the books. I think for narrative balance purposes, a lasegun would need a certain amount of power before it would explode a shield. Like you can’t just put a miniaturized lasegun on a hunter seeker… laseguns need to be big.

    Laze guns interact with the sheilds causing basically the destructive power of Tsar Bomba+, but knives/swords (when used properly, as Gurney Halleck taught Paul to do) pierce the sheilds. Read the book nerd.

      It is kind of ridiculous that the Imperium turns entire goddamn planets into factories but still plays the “lost technology” card for things they have working examples of. I know they’re not a shining example of inquiry and skepticism in general, but you’d fucking figure the blow-shit-up department gets carte blanch. You have genius-level superhumans who are three centuries old and those guys are your soldiers. What the fuck is stopping the laser pewpew R&D effort?

        Yeah their final arguement is it’s too much sci-fantasy at it’s core for them and that is pretty accurate, everything serves the lore instead of the science being… anything reality based at all.

        Whats stopping Imperium R&D is a mix of multiple things ranging from Byzantine beurocracy so advanced the Romans are calling it inefficient to the fact that if you build the gun wrong it gets possessed by a literal Daemon. Also the space marines are generally getting the best shit, its the guardsmen who are getting the lower grade shit.

        Also the Mechanicus is building new tech its just slow as balls and usually objectively worse than golden age tech which is capable of fucking with time and using the anomolies to annihilate an enemy ship. And the ship that does that may not even be a military vessal by design.
