The potential for untrustworthy conversational agents presents a significant threat for covert social manipulation. Taking inspiration from Frank Herbert's "Dune", where the Bene Gesserit Sisterhood uses the Voice for influence, manipulation, and control of people, we explore how generative AI provides a way to implement individualized influence at industrial scales. Already, these models can manipulate communication across text, image, speech, and most recently video. They are rapidly becoming affordable enough for any organization of even moderate means to train and deploy. If employed by malicious actors, they risk becoming powerful tools for shaping public opinion, sowing discord, and undermining organizations from companies to governments. As researchers and developers, it is crucial to recognize the potential for such weaponization and to explore strategies for prevention, detection, and defense against these emerging forms of sociotechnical manipulation.

I have questions about Denis Villeneuve's Dune: Part Two. If the Fremen have lasers, why don't they just shoot the sand harvesters and run away? Why don't they use their sandworms until the last battle? Wouldn't it make more sense to fight the other great houses on Arrakis itself, where they have sandworms, rather than board ships off-world to go off to war? If Paul (Timothée Chalamet) has to invade the galaxy at the end, why bother marrying the daughter of the emperor he just deposed?

Don't tell Frank Herbert (or the people at Thinx), but he actually came up with a pretty genius pair of menstrual underwear. Only, well, his was outerwear--and it did a lot more than collect blood and endometrial lining. Herbert's invention is, of course, the stillsuit. One of the iconic pieces of tech in his novel Dune--and an iconic piece of sci-fi tech, period--it's an invention born of necessity. Arrakis, where most of the novel takes place, is a desert; to survive, the planet's native Fremen construct form-fitting suits that collect all of their moist excretions--sweat, urine, feces, droplets from exhaled breath--and recycle them into potable water.
